PART I

ITEM 1. Business

Overview

We are a clinical-stage biopharmaceutical company dedicated to bringing a first-in-class pipeline of programmed cellular immunotherapies to patients with cancer and autoimmune diseases. Our development of programmed cellular immunotherapies is based on a simple notion: we believe that better cell therapies start with better cells.

To create better cell therapies, we have pioneered a therapeutic approach that we generally refer to as cell programming: we create and engineer human induced pluripotent stem cells (iPSCs) to incorporate novel synthetic controls of cell function; we generate a clonal master iPSC line for use as a renewable source of cell manufacture; and we direct the fate of the clonal master iPSC line to produce our cell therapy product candidate. Analogous to master cell lines used to manufacture biopharmaceutical drug products such as monoclonal antibodies, we believe clonal master iPSC lines can be used to mass produce multiplexed-engineered, cellular immunotherapies which are well-defined and uniform in composition, can be stored in inventory for off-the-shelf availability, can be combined and administered with standard-of-care therapies, and can have significant patient reach.

Utilizing our proprietary iPSC product platform, we are advancing off-the-shelf, multiplexed-engineered natural killer (NK) cell and T-cell product candidates which are selectively designed, incorporate novel synthetic controls of cell function, and are intended to deliver multiple therapeutic mechanisms to patients for the treatment of cancer and autoimmune disease. We have a deep pipeline of iPSC-derived, chimeric antigen receptor (CAR)-targeted NK cell and T-cell product candidates currently under development with multiple clinical trials ongoing:

Our Approach

The use of human cells as therapeutic entities has disease-transforming potential, and compelling evidence of medical benefit for cell therapy exists across a broad spectrum of severe, life-threatening diseases. Clinical investigation of cellular immunotherapy has been rapidly expanding. One particular form of cell-based cancer immunotherapy, CAR T-cell therapy, has emerged as a revolutionary and potentially curative treatment for patients with certain hematologic malignancies. In fact, multiple CAR T-cell therapies have now been approved by the United States Food and Drug Administration (FDA) for the treatment of relapsed / refractory B-cell malignancies and relapsed / refractory multiple myeloma.

Cell-based cancer immunotherapies undergoing clinical investigation today most often rely on the use of autologous, or a patient’s own, cells. The requirement to source, engineer, expand and deliver cells patient-by-patient is logistically complex, resource intensive and expensive, and can result in significant batch-to-batch variability in product identity, purity and potency as well as in manufacturing failures. Significant hurdles remain to ensure that cell-based cancer immunotherapies can be consistently manufactured and reliably delivered in a cost-effective manner and at the scale necessary to support broad patient access and widespread commercialization.

Human iPSCs possess the unique dual properties of unlimited self-renewal and differentiation potential into all cell types of the body. Our proprietary iPSC product platform combines multiplexed-engineering of human iPSCs with single-cell selection to create clonal master iPSC lines. Rather than rely on the use of donor cells, or a patient’s own cells, we seek to use clonal master iPSC lines to manufacture, develop and commercialize CAR NK cell and CAR T-cell product candidates which are selectively designed, incorporate novel synthetic controls of cell function, can be mass produced at significant scale in a cost-effective manner, are well-defined and uniform in composition, and can be stored in inventory and delivered off-the-shelf to maximize patient reach. We believe our therapeutic approach is uniquely designed to overcome numerous limitations associated with the production of cell therapies using patient- or donor-sourced cells. Our proprietary iPSC product platform is supported by an intellectual property portfolio of over 500 issued patents and 500 pending patent applications.

Our Strategy

Our mission is to bring off-the-shelf, iPSC-derived cellular immunotherapies with disease-transforming potential to patients with cancer and autoimmune diseases. The key pillars of our strategy include:

We have established a proprietary iPSC product platform and have amassed significant internal expertise in the production of off-the-shelf, multiplexed-engineered, iPSC-derived NK and T-cell product candidates for therapeutic use. Our proprietary iPSC product platform includes: generating, engineering, isolating and characterizing single-cell iPSC clones; creating, qualifying, and cryopreserving clonal master iPSC lines; differentiating clonal master cell iPSC lines to produce NK cells and T-cells at scale; cryopreserving and storing iPSC-derived NK cells and T-cells under conditions that support multi-year stability; applying our regulatory experience and quality expertise to enable clinical investigation of off-the-shelf, multiplexed-engineered, iPSC-derived cellular immunotherapy candidates. We have established and operate our own fully-integrated Good Manufacturing Practice (GMP) facility for scaled manufacture of iPSC-derived NK cells and T-cells, which is intended to support all phases of clinical development as well as initial commercialization.

We believe there is significant opportunity for the development of iPSC-derived, cell-based cancer immunotherapies which have the potential to be selectively designed to incorporate multiple therapeutic mechanisms of action, stored in inventory for off-the-shelf availability, and combined and administered with standard-of-care, outpatient treatment regimens to increase patient reach. We are currently advancing multiple off-the-shelf, multiplexed-engineered, iPSC-derived CAR NK cell and CAR T-cell cancer immunotherapy candidates in first-in-human clinical studies. In conducting these studies of our product candidates, we seek to treat patients with cancer who are relapsed or refractory to FDA-approved therapies where the unmet need is high. We also seek to mount a multi-antigen attack against cancer by combining our product candidates with standard-of-care therapies, such as monoclonal antibody therapy. To this end, we have incorporated a proprietary high-affinity, non-cleavable CD16 (hnCD16) Fc receptor into several of our CAR-targeted cell product candidates, which receptor has two unique features designed to augment antibody-dependent cellular

cytotoxicity (ADCC): a high-affinity homozygous 158V variant to promote binding to the Fc domain of IgG antibodies, and a modification to block its cleavage and down-regulation upon receptor activation. As a result, certain of our CAR NK cell and CAR T-cell product candidates target more than one antigen expressed on tumor cells in combination with monoclonal antibody therapy, which may lead to deeper and more durable responses in cancer patients. Additionally, in the setting of solid tumors, we also seek to overcome certain of the key limitations that have stifled anti-tumor activity of autologous CAR T-cell therapy by incorporating novel synthetic receptors into our cell product candidates including, for example, a novel synthetic CXCR2 receptor to promote effector cell trafficking to the tumor site and a novel synthetic TGFβ receptor to resist immunosuppressive signals in the tumor microenvironment.

In a ground-breaking academic clinical study published in Nature Medicine in September 2022, an investigational autologous CD19-targeted CAR T-cell therapy was administered to five patients with systemic lupus erythematosus (SLE). Rapid B-cell depletion and elimination of auto-antibody production was observed following infusion of therapy, and all patients achieved clinical remission with significant improvement in Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) score. Given that the targeting and rapid depletion of B cells are common mechanisms of action for the successful treatment of B-cell malignancies and certain autoimmune diseases, we believe that our off-the-shelf CAR NK cell and CAR T-cell product candidates may be uniquely suited to address a broad range of autoimmune diseases through the potential reset of the CD19+ B-cell lineage. We are currently conducting study start-up of a multi-center, Phase 1 clinical trial of our FT819 CAR T-cell program for the treatment of patients with moderate to severe SLE, including those with active lupus nephritis or with active extrarenal lupus. In addition, we are currently assessing the potential to expand our FT522 and FT576 CAR NK programs beyond oncology into autoimmunity, including each program’s potential to treat certain autoimmune diseases by more broadly targeting autoantibody-producing lineages.

FT522 is our first iPSC-derived cell product candidate to incorporate our novel alloimmune defense receptor (ADR) technology, which is designed to reduce or eliminate the need for administration of intense conditioning chemotherapy to patients receiving cellular immunotherapy. FT522 incorporates a synthetic ADR receptor that targets the cell surface receptor 4-1BB (CD137), a member of the tumor necrosis factor receptor superfamily that is upregulated on activated CD4+, CD8+, and regulatory T-cells as well as activated NK cells of the host immune system. The ADR receptor is designed to (a) selectively recognize and destroy alloreactive host immune cells that would otherwise be capable of rejecting the product candidate, (b) maintain other components of the host immune system to preserve hematopoietic cell function, and (c) activate the product candidate to enhance its potency and persistence. Published preclinical studies have shown that ADR-armed allogeneic cells are protected from both T- and NK-cell mediated rejection (Mo et al. Nature Biotechnology, 39, 56–63 (2021)), providing proof-of-concept that ADR-armed allogeneic cells can persist and function in immunocompetent patients. We believe we have the opportunity to establish clinical proof-of-concept for our ADR technology early in dose escalation of our ongoing multi-center, Phase 1 study for FT522 in B-cell lymphoma. In addition, we are preclinically assessing the potential to expand our FT522 program into autoimmune diseases.

Our Off-the-shelf, Multiplexed-engineered, iPSC-derived Cellular Immunotherapy Pipeline

Utilizing our proprietary iPSC product platform, we are developing off-the-shelf, multiplexed-engineered CAR NK cell and CAR T-cell product candidates for the treatment of cancer and autoimmune diseases. Our iPSC-derived cell product candidates are selectively designed to incorporate novel synthetic controls of cell function, can be mass produced at significant scale in a cost-effective manner, are well-defined and uniform in composition, and can be stored in inventory and delivered off-the-shelf to maximize patient reach. We believe our therapeutic approach is uniquely designed to overcome numerous limitations associated with the production of cell therapies using patient- or donor-sourced cells.

FT819: CAR T-cell Program

FT819 is our first iPSC-derived CAR T-cell product candidate and, to our knowledge, is the first-ever iPSC-derived CAR T-cell product candidate to undergo clinical investigation in the world. FT819 was developed under an ongoing sponsored research collaboration with MSKCC that is being led by Michel Sadelain, M.D., Ph.D., Director of the Center for Cell Engineering and the Stephen and Barbara Friedman Chair at MSKCC. Dr. Sadelain was awarded the 2024 Breakthrough Prize in Life Sciences for trailblazing the development of CAR T-cell immunotherapy.

We have exclusively licensed from MSKCC foundational intellectual property covering iPSC-derived cellular immunotherapy, including T-cells and NK cells derived from iPSCs engineered with CARs, for human therapeutic use. We have also licensed from MSKCC intellectual property covering compositions of novel CAR constructs, including the use of a novel 1XX co-stimulatory domain, and of genetically engineered CAR T-cells, including methods of making these cells using CRISPR for certain targeted gene modifications. Embodiments of this additional intellectual property include preclinical data published by Dr. Sadelain demonstrating that directing a CD19-specific CAR to the T-cell receptor alpha chain (TRAC) locus resulted in uniform CAR expression in human peripheral blood T-cells, enhanced T-cell potency, and delayed effector T-cell differentiation and exhaustion (Eyquem et al. Nature. 543, 113–117, 2017), and that CAR T-cells utilizing a novel 1XX CAR signaling domain exhibited enhanced antitumor activity, persistence and long-term cytotoxicity as well as a decrease in T-cell exhaustion (Feucht et al. Nature Medicine. 25, 82–88, 2019).

FT819 incorporates two novel synthetic controls of cell function: a novel 1XX CAR construct inserted directly into the TRAC locus that targets CD19; and the complete disruption of TCR expression for the prevention of graft-versus-host disease (GvHD), a potentially life-threatening complication associated with allogeneic T-cell therapy. Together, these features of FT819 are designed to induce antigen-specific cytotoxicity, enhance CAR activity through TRAC-regulated expression, and mitigate risk of GvHD. In preclinical studies, we have shown that iPSC-derived TCR-CAR+ CAR T-cells targeting CD19:

Additional preclinical data published in August 2022 showed the generation of iPSC-derived TCR-CAR+ CD8αβ T-cells, which were able to repeatedly lyse tumor cells in vitro and durably control leukemia in vivo, with persistence in the bone marrow, spleen, and blood, in a systemic NALM6 leukemia model (Sjoukje et al. Nature Biomedical Engineering. 6, 1284–1297, 2022).

We are currently evaluating FT819 in an ongoing, multi-center, Phase 1 clinical trial to assess its safety, pharmacokinetics, clinical activity, and to determine the recommended Phase 2 dose, in patients with relapsed / refractory B-cell malignancies, including B-cell lymphoma (BCL). In addition, we have expanded our clinical investigation into autoimmune diseases. In July 2023, the FDA allowed our Investigational New Drug (IND) application for the conduct of a multi-center, Phase 1 clinical trial of FT819 to assess its safety and clinical activity, and to determine the recommended Phase 2 dose, in patients with moderate to severe SLE, including those with active lupus nephritis or active extrarenal lupus.

B-cell Malignancies

At the 2022 American Society of Hematology (ASH) Annual Meeting, we presented interim clinical data for 8 patients with aggressive large B-cell lymphoma (LBCL) treated with a single dose of FT819 in our ongoing Phase 1 study (see table below). Patients were heavily pre-treated having received a median of 4.5 prior lines of therapy (range 3-7), including 6 of 8 patients (75%) having previously received autologous CD19-targeted CAR T-cell therapy. Each of the 8 patients received standard conditioning chemotherapy consisting of cyclophosphamide (Cy) at 500 mg/m2 and fludarabine (Flu) at 30 mg/m2 for three days followed by a single dose of FT819 ranging from 90 million cells to 360 million cells. As of a September 8, 2022 data cutoff date:

We amended the FT819 clinical protocol to allow for the use of bendamustine at 90 mg/m2 for two days as an alternative to Cy / Flu conditioning chemotherapy. Dose escalation in the multi-center, Phase 1 clinical trial of FT819 is currently ongoing at a single dose of FT819 at 1.08 billion cells for BCL. We currently do not plan to assess FT819 at a dose level above 1.08 billion cells, and any further clinical development of FT819 in patients with relapsed / refractory B-cell malignancies will be determined upon completion of the dose escalation at this current dose level.

Autoimmune Diseases

Autoimmune diseases affect organs throughout the body and are often characterized by the presence of auto-antibodies, which are produced by aberrant B cells and can attack healthy cells and tissues. In a ground-breaking academic clinical study published in Nature Medicine in September 2022, an investigational autologous CD19-targeted CAR T-cell therapy was administered to five patients with SLE. Rapid B-cell depletion and elimination of auto-antibody production was observed following infusion of therapy, and all patients achieved clinical remission with significant improvement in SLEDAI-2K score. Naïve B-cell reconstitution occurred after an average time of 110 days of CAR T-cell infusion.

Given that the targeting and rapid depletion of B cells is a common mechanism of action for the successful treatment of B-cell malignancies and certain autoimmune diseases, we are expanding our clinical investigation of FT819 to autoimmune diseases. We are currently conducting study start-up of a multi-center, Phase 1 clinical trial of FT819 for the treatment of patients with moderate to severe SLE, including those with active lupus nephritis or with active extrarenal lupus. We intend to treat patients with standard conditioning chemotherapy followed by a single dose of FT819, with dose escalation initiating at 360 million cells. Primary endpoints include the incidence of adverse events and the frequency of dose-limiting toxicities, and secondary endpoints include characterizing pharmacokinetics and pharmacodynamics, assessing disease-related biomarkers, and evaluating efficacy.

We believe FT819 has potential applicability across multiple autoimmune diseases.

FT825: CAR T-cell Program

FT825 is our first iPSC-derived CAR T-cell product candidate for the treatment of solid tumors being developed in collaboration with Ono Pharmaceutical. The use of autologous CAR T-cell therapies for the treatment of solid tumors has been hampered by tumor-associated antigen heterogeneity, inefficient CAR T-cell trafficking to the tumor, immunosuppression inherent to the tumor microenvironment, and differentiating tumor-associated antigen expression between tumor and normal tissue. To date there are no FDA-approved CAR T-cell therapies for the treatment of solid tumors. FT825 is specifically designed to overcome these challenges in treating solid tumors, and incorporates seven novel synthetic controls of cell function: a 1XX CAR construct inserted directly into the TRAC locus that is armed with a novel human epidermal growth factor receptor 2 (HER2) binding domain designed to preferentially target tumor cells; a novel high-affinity 158V, non-cleavable CD16 (hnCD16) Fc receptor that has been modified to prevent its down-regulation and to enhance ADCC; a synthetic IL-7/IL-7 receptor fusion (IL-7RF), a potent cytokine complex that is intended to promote T-cell stemness; a synthetic CXCR2 receptor to promote cell trafficking; a synthetic TGFβ receptor to redirect immunosuppressive signals in the tumor microenvironment; the complete elimination of CD38 expression to promote persistence and function in high oxidative stress environments; and the complete disruption of TCR expression for the prevention of GvHD.

In preclinical studies of FT825 presented at the 2023 Society for Immunotherapy of Cancer (SITC) Annual Meeting, the product candidate’s HER2 binding domain (H2CasMab-2) exhibited robust, dose-dependent cytolytic activity in vitro against both HER2-high and HER2-low cell lines from multiple tumor types, and showed a highly selective and differentiated targeting profile in vitro against HER2-expressing cancer cell lines from healthy tissue in comparison to other HER2-directed agents such as trastuzumab (see figure below). FT825 also exhibited enhanced trafficking and resistance to TGFβ-induced suppression in vitro (see figure below). In addition to its CAR-mediated anti-tumor activity against HER2, co-activation of the product candidate’s hnCD16 Fc receptor through combination with monoclonal antibody therapy showed enhanced anti-tumor activity.

In January 2024, and alongside our collaborator Ono Pharmaceutical (see “Our Partnership with Ono Pharmaceutical”), we announced the initiation of enrollment of a multi-center, Phase 1 clinical trial of FT825 for the treatment of advanced solid tumors. The Phase 1 study is designed to evaluate the safety and activity of a single dose of FT825 as monotherapy or in combination with monoclonal antibody therapy. The dose escalation and dose expansion portions of the Phase 1 study will evaluate safety, tolerability, and pharmacokinetics as well as anti-tumor activity by overall response rate, duration of response and disease control rate.

FT522: CAR NK Cell Program

FT522 is our first iPSC-derived CAR NK cell product candidate that incorporates our novel Alloimmune Defense Receptor (ADR) technology, which is designed to reduce or eliminate the need for administration of intense conditioning chemotherapy to

patients receiving cellular immunotherapy. While approved autologous CAR T-cell therapies have demonstrated compelling efficacy in treating patients with relapsed / refractory hematologic malignancies, several key challenges limit its adoption and patient reach including the need to co-administer conditioning chemotherapy to patients. Conditioning chemotherapy induces toxicities, necessitates administration in large hospitals and treatment centers with intensive care units, and prevents effective combination with standard-of-care treatment regimens widely used in the community setting. Its use has also been associated with treatment-emergent secondary malignancies, such as myelodysplastic syndrome. In addition, the FDA recently announced an investigation into reports of secondary T-cell malignancies among patients receiving autologous CAR T-cell therapies and, as part of such investigation, the FDA is requiring that all commercially-approved BCMA-directed or CD19-directed autologous CAR T-cell therapies include a black box warning describing the risk of T-cell malignancies on each product’s label.

FT522 incorporates five novel synthetic controls of cell function: a proprietary CAR that targets CD19; a novel high-affinity 158V, non-cleavable CD16 (hnCD16) Fc receptor that has been modified to prevent its down-regulation and to enhance ADCC in combination with a monoclonal antibody; an IL-15/IL-15 receptor fusion (IL-15RF), a potent cytokine complex that is intended to augment NK cell activity; the complete elimination of CD38 expression to promote persistence and function in high oxidative stress environments; and a novel synthetic ADR targeting the cell surface receptor 4-1BB (CD137), a member of the tumor necrosis factor receptor superfamily that is upregulated on activated CD4+, CD8+, and regulatory T-cells as well as activated NK cells of the host immune system. In combination with monoclonal antibody therapy, these features of FT522 are designed to reduce or eliminate the need for administration of intense conditioning chemotherapy to patients, enable dual-antigen targeting of antigens expressed on B cells, and extend the functional persistence of FT522.

In preclinical studies, we showed that ADR-armed CAR NK cells selectively targeted and eliminated alloreactive immune cells in an in vitro co-culture assay with allogeneic peripheral blood mononuclear cells (see figure below); targeted and eliminated activated T-regulatory cells, overcoming a major suppressive mechanism associated with poor anti-tumor activity; and were potentiated through 4-1BB engagement, promoting NK cell expansion and persistence. In addition, in a disseminated Nalm6 leukemia model comprised of alloreactive T-cells and CD19+ tumor cells resistant to T-cell killing (MHC class 1-null), ADR-armed, CD19-targeted, iPSC-derived CAR NK cells exhibited uncompromised effector function in vivo compared to ADR-null, CD19-targeted, iPSC-derived CAR NK cells, suggesting that ADR-armed NK cells functionally persist, proliferate, and kill tumor cells while resisting rejection by alloreactive T-cells. These preclinical data suggest that FT522 has the potential to robustly deplete CD19+ B cells, evade host immune cell rejection, and drive clinical responses without administration of intense conditioning chemotherapy to patients.

B-cell Lymphoma

We are currently conducting a multi-center, Phase 1 clinical trial of FT522 to assess its safety, pharmacokinetics, and clinical activity in patients with relapsed / refractory BCL. The Phase 1 study includes two regimens: Regimen A, or the “conditioning” arm, which consists of 3 days of standard conditioning chemotherapy; 1 dose of rituximab; and 3 doses of FT522; and Regimen B, or the “no conditioning” arm, which consists of 1 dose of rituximab and 3 doses of FT522 without conditioning chemotherapy. Enrollment into Regimen A is ongoing at the first dose level of 300 million cells per dose and, upon clearance of dose-limiting toxicities at this first dose level, we intend to initiate enrollment into Regimen B at the first dose level of 300 million cells per dose. Each regimen may proceed with dose escalation independently. We believe we have the opportunity to establish clinical proof-of-concept for our ADR technology, and for our FT522 program without conditioning chemotherapy, early in dose escalation.

Autoimmune Diseases

We are also assessing the potential to expand our FT522 program into autoimmune diseases. While therapeutic strategies designed to deplete B cells, including treatment with CD20-targeted monoclonal antibody therapy, have been shown effective for

induction and maintenance of remission in certain patients with autoimmune diseases, aberrant production of auto-antibodies by plasma cells is also an inherent characteristic of autoimmune diseases. Notably, recent findings suggest that long-lived plasma cells often accumulate later in the course of disease and are refractory to immunosuppressants and B-cell depletion therapies, leading to the persistent secretion of auto-antibodies despite B-cell targeted intervention strategies. We believe our FT522 program in combination with CD38-targeted monoclonal antibody therapy may be uniquely suited to address a broad range of autoimmune diseases through the potential reset of both CD19+ B-cell and CD38+ plasma-cell autoantibody-producing lineages.

FT576: CAR NK Cell Program

FT576 is our iPSC-derived CAR NK cell product candidate that is designed to target B-cell maturation antigen (BCMA) expressed on plasma cells, a type of immune cell that is found mainly in the bone marrow and is responsible for making and secreting antibodies to fight infection. Several drugs that target plasma cells, including CD38-targeted monoclonal antibody therapy, have been approved for the treatment of multiple myeloma, a deadly form of blood cancer that is characterized by uncontrolled growth of abnormal plasma cells in the bone marrow. In addition, autologous CAR T-cell therapies have shown significant efficacy in multiple myeloma, and two autologous CAR T-cell therapies targeting BCMA have been approved by the FDA. Despite these advancements, multiple myeloma is rarely cured, creating a high unmet need for patients with relapsed / refractory disease.

We entered into a license agreement with the Max Delbrück Center for Molecular Medicine (MDC) under which we were granted certain exclusive rights to intellectual property covering novel humanized CAR constructs that uniquely and specifically bind BCMA. In data published by MDC scientists, BCMA-targeted CAR T-cells armed with its unique humanized extracellular antigen-binding domains showed higher affinity and greater specificity than other BCMA-targeted antigen-binding domains. These differentiated properties conveyed both greater selectivity in recognizing plasma cells and more robust killing of plasma cells in vitro, including malignant plasma cells with low expression levels of BCMA. Additionally, in in vivo proof-of-concept studies, MDC scientists demonstrated that BCMA-targeted CAR T-cells mediated anti-tumor activity in xenotransplant mouse models of B-cell lymphoma, where BCMA surface expression is typically up to 4-fold lower as compared to mouse models of multiple myeloma.

FT576 incorporates four novel synthetic controls of cell function: a proprietary CAR that targets BCMA; a novel high-affinity 158V, non-cleavable CD16 (hnCD16) Fc receptor that has been modified to prevent its down-regulation and to enhance ADCC; an IL-15/IL-15 receptor fusion (IL-15RF), a potent cytokine complex that is intended to augment NK cell activity; and the complete elimination of CD38 expression to promote persistence and function in high oxidative stress environments. In combination with CD38-targeted monoclonal antibody therapy, these features of FT576 are designed to avoid NK cell fratricide, enable dual-antigen targeting of BCMA and CD38 antigens expressed on plasma cells, and extend functional persistence. In preclinical studies, FT576 demonstrated that the high-avidity binding of its BCMA-targeted CAR construct enabled sustained tumor control against various multiple myeloma cell lines, including in long-term in vivo xenograft mouse models.

Multiple Myeloma

We are currently evaluating FT576 in an ongoing, multi-center, Phase 1 clinical trial to assess its safety, pharmacokinetics, and clinical activity in patients with relapsed / refractory multiple myeloma, and to determine the recommended Phase 2 dose and schedule, as monotherapy (Regimen A) and in combination with CD38-targeted monoclonal antibody therapy (Regimen B). At the 2022 ASH Annual Meeting, we presented interim clinical data for 9 patients with relapsed / refractory multiple myeloma treated with a single dose of FT576, including six patients in Regimen A and three patients in Regimen B treated in our ongoing Phase 1 study. Patients were heavily pre-treated having received a median of 5 prior lines of therapy (range 3-10), including 6 of 9 patients (67%) that were refractory to last therapy. Each of the 9 patients received standard conditioning chemotherapy consisting of cyclophosphamide (Cy) at 300 mg/m2 and fludarabine (Flu) at 30 mg/m2 for three days followed by a single dose of FT576 ranging from 100 million cells to 300 million cells. As of an October 7, 2022 data cutoff date:

We amended the FT576 study protocol to allow for the use of bendamustine at 90 mg/m2 for two days as an alternative to Cy / Flu conditioning chemotherapy. Dose escalation in the multi-center, Phase 1 clinical trial of FT576 is currently ongoing, with three-dose cohorts being assessed in both Regimens A and B at up to 2.5 billion cells per dose. We currently do not plan to assess FT576 at a dose level above 2.5 billion cells per dose, and any further clinical development of FT576 in patients with relapsed / refractory multiple myeloma will be determined upon completion of the dose escalation at this current dose level.

Autoimmune Diseases

We are also assessing the potential to expand our FT576 program into autoimmunity. Auto-antibody-secreting plasma cells are increasingly recognized as essential drivers of pathophysiology in certain autoimmune diseases, such as myasthenia gravis. Existing myasthenia gravis therapies do not adequately or specifically target long-lived plasma cells that reside in dedicated survival niches in the bone marrow or inflamed tissue. These long-lived plasma cells are unresponsive to immunosuppressive and B-cell therapies. We believe our FT576 program, which has the potential to target BCMA expressed on the surface of long-lived plasma cells, may represent an innovative therapeutic strategy for the treatment of certain autoimmune diseases.

Discontinued Product Candidates

Janssen Collaboration. During 2022, Janssen Biotech, Inc. (Janssen) exercised a commercial option for two collaboration candidates: an iPSC-derived CAR NK cell product candidate for the treatment of B-cell lymphoma, for which the FDA allowed an IND application in December 2022; and an iPSC-derived CAR NK cell product candidate for the treatment of multiple myeloma, for which the companies were preparing to submit an IND application to the FDA in early 2023. In addition, the companies were researching and preclinically developing two iPSC-derived CAR T-cell programs for the treatment of solid tumors. On January 3, 2023, we received notice of termination from Janssen of our collaboration and option agreement dated April 2, 2020 by and between the parties (the Janssen Agreement), pursuant to which the companies had agreed to collaborate to develop iPSC-derived CAR NK cell and CAR T-cell product candidates for the treatment of cancer. The termination was finalized on April 3, 2023 and, during the first quarter of 2023, we completed wind down our activities with Janssen, including discontinuing development of all collaboration products.

Internal Programs. On January 5, 2023, we announced the completion of a strategic review of our NK cell programs and our election to focus on advancing our most innovative and differentiated product candidates, which have a multiplexed-engineered cellular framework of novel synthetic controls designed to promote multi-antigen targeting, increase potency, extend functional persistence, and enable patient dosing with reduced conditioning chemotherapy. As a result of our NK cell program prioritization, our FT516, FT596, FT538, and FT536 NK cell programs were discontinued.

Workforce Reduction. As a result of the termination of the Janssen collaboration and the NK cell program prioritization, during the first quarter of 2023 we reduced our workforce to approximately 220 employees. We incurred charges of $12.9 million for severance and other employee termination-related costs during the year ended December 31, 2023.

Our Partnership with Ono Pharmaceutical

Under a collaboration and option agreement with Ono Pharmaceutical Co. Ltd. (Ono) entered into in September 2018 and amended in June 2022 (the Ono Agreement), we are conducting research and preclinical development of iPSC-derived CAR NK cell and CAR T-cell product candidates for the treatment of solid tumors.

In November 2022, we announced that Ono had exercised its preclinical option to FT825 / ONO-8250, an off-the-shelf, multiplexed-engineered, iPSC-derived CAR T-cell product candidate targeting HER2-expressing solid tumors (also referred to as Candidate 2 below), and that we exercised our preclinical option to co-develop and co-commercialize FT825 / ONO-8250 in the United States and Europe under a joint arrangement with Ono. As a result, we received an option exercise fee of $12.5 million from

Ono. In January 2024, we announced the initiation of enrollment of a Phase 1 clinical trial of FT825 / ONO-8250 for the treatment of advanced solid tumors.

The companies are also currently conducting preclinical development of a second iPSC-derived CAR-targeted effector cell product candidate for the treatment of solid tumors (referred to as Candidate 3 below) under the Ono Agreement.

Under the original Ono Agreement entered into in September 2018, we and Ono intended to research and preclinically develop two iPSC-derived CAR T-cell product candidates, one of which was designated to target an antigen expressed on certain lymphoblastic leukemias (Candidate 1) and the second of which was designated to target an antigen expressed on certain solid tumors (Candidate 2) (each a Candidate and, collectively, the Candidates). We granted to Ono, during a specified period of time, a preclinical option to obtain an exclusive license under certain intellectual property rights to develop and commercialize: (a) Candidate 1 in Asia, where we retained rights for development and commercialization in all other territories of the world; and (b) Candidate 2 in all territories of the world, where we retained rights to co-develop and co-commercialize Candidate 2 in the United States and Europe under a joint arrangement with Ono under which we are eligible to share at least 50% of the profits and losses. We maintained worldwide rights of manufacture for each Candidate. For each Candidate, the preclinical option expired upon the earliest of: (a) the achievement of the pre-defined preclinical milestone under the joint development plan; (b) termination by Ono of research and development activities for the Candidate; and (c) the date that is the later of (i) four years after the effective date, and (ii) completion of all applicable activities contemplated under the joint development plan. Ono paid us an upfront, non-refundable and non-creditable payment of $10.0 million in connection with entering into the Ono Agreement. Additionally, as consideration for our conduct of research and preclinical development under a joint development plan, Ono agreed to pay us annual research and development fees set forth in the annual budget included in the joint development plan, which fees were estimated to be $20.0 million in aggregate over the course of the joint development plan.

In December 2020, we entered into a letter agreement with Ono pursuant to which Ono delivered to us proprietary antigen binding domains targeting an antigen expressed on certain solid tumors for incorporation into Candidate 2 and paid us a milestone fee of $10.0 million for further research and development of Candidate 2. In addition, Ono terminated all further research and development with respect to Candidate 1, and we retained all rights to research, develop and commercialize Candidate 1 throughout the world without any obligation to Ono.

In June 2022, we entered into an amendment with Ono to the Ono Agreement (the 2022 Ono Amendment). Pursuant to the 2022 Ono Amendment, the companies agreed to designate an additional antigen expressed on certain solid tumors for research and preclinical development, and Ono agreed to contribute to us proprietary antigen binding domains targeting such additional solid tumor antigen (Candidate 3). In addition, for both Candidate 2 and Candidate 3, the companies expanded the scope of the collaboration to include the research and development of iPSC-derived CAR NK cell product candidates (in addition to iPSC-derived CAR T-cell product candidates) targeting the designated solid tumor antigens. Similar to Candidate 2, we granted to Ono, during a specified period of time, a preclinical option to obtain an exclusive license under certain intellectual property rights, subject to payment of an option exercise fee to us by Ono, to develop and commercialize Candidate 3 in all territories of the world, where we retained rights to co-develop and co-commercialize Candidate 3 in the United States and Europe under a joint arrangement with Ono under which we are eligible to share at least 50% of the profits and losses. We maintained worldwide rights of manufacture for Candidate 3. The preclinical option expires upon the earlier of: (a) September 30, 2024, or (b) the achievement of the pre-defined preclinical milestone under the joint development plan for Candidate 3. Subject to payment to us of an extension fee by Ono, Ono may choose to defer its decision to exercise the preclinical option until no later than June 2026. Ono agreed to pay us annual research and development fees set forth in the annual budget included in the joint development plan for Candidate 3.

Under the terms of the Ono Agreement (as amended by the 2022 Ono Amendment), for Candidate 2 and for Candidate 3 (subject to exercise by Ono of its preclinical option to Candidate 3), we are eligible to receive additional payments upon the achievement of certain clinical, regulatory and commercial milestones (the Ono Milestones) with respect to each Candidate in an amount up to $843.0 million in aggregate, with the applicable milestone payments for the United States and Europe subject to reduction by 50% if we elect to co-develop and co-commercialize the Candidate in the United States and Europe as described above. In addition, in those territories where Ono has exclusive rights of commercialization, we are eligible to receive tiered royalties (Royalties) ranging from the mid-single digits to the low-double digits based on annual net sales by Ono for each Candidate in such territories, with the Royalties subject to certain reductions.

On November 30, 2023, we entered into an amendment with Ono to the Ono Agreement (the 2023 Ono Amendment). Under the 2023 Ono Amendment, aggregate estimated research and development fees have been increased by approximately $1.4 million, for a total estimated $30.7 million in aggregate research and development fees over the course of the joint development plan.

The Ono Agreement will terminate with respect to a Candidate if Ono does not exercise its option for a Candidate within the option period, or in its entirety if Ono does not exercise any of its options for the Candidates within their respective option periods. In addition, either party may terminate the Ono Agreement in the event of breach, insolvency or patent challenges by the other party; provided, that Ono may terminate the Ono Agreement in its sole discretion (x) on a Candidate-by-Candidate basis at any time after the second anniversary of the effective date of the Ono Agreement or (y) on a Candidate-by-Candidate or country-by-country basis at any

time after the expiration of the option period, subject to certain limitations. The Ono Agreement will expire on a Candidate-by-Candidate and country-by-country basis upon the expiration of the applicable royalty term, or in its entirety upon the expiration of all applicable payment obligations under the agreement.

Our Intellectual Property

Overview

We seek to protect our product candidates and our cell programming technology through a variety of methods, including seeking and maintaining patents intended to cover our products and compositions, their methods of use and processes for their manufacture, our platform technologies and any other inventions that are commercially important to the development of our business. We seek to obtain domestic and international patent protection and, in addition to filing and prosecuting patent applications in the United States, we typically file counterpart patent applications in additional countries where we believe such foreign filing is likely to be beneficial, including Europe, Japan, Canada, Australia and China. We continually assess and refine our intellectual property strategy in order to best fortify our position, and file additional patent applications when our intellectual property strategy warrants such filings. We also rely on know-how, continuing technological innovation and in-licensing opportunities to develop and maintain our proprietary position. We have entered into exclusive license agreements with various academic and research institutions to obtain the rights to use certain patents for the development and commercialization of our product candidates.

As of February 15, 2024, our intellectual property portfolio is composed of over 450 issued patents and 150 patent applications that we license from academic and research institutions, and over 450 issued patents or pending patent applications that we own. These patents and patent applications generally provide us with the rights to develop our product candidates in the United States and worldwide. This portfolio covers compositions of programmed cellular immunotherapies, our cell programming approach for enhancing the therapeutic function of cells ex vivo, and our platform for industrial-scale iPSC generation and engineering. We believe that we have a significant intellectual property position and substantial know-how relating to the programming of hematopoietic and immune cells and to the derivation, genetic engineering, and differentiation of iPSCs.

We cannot be sure that patents will be granted with respect to any of our owned or licensed pending patent applications or with respect to any patent applications we may own or license in the future, nor can we be sure that any of our existing patents or any patents we may own or license in the future will be useful in protecting our technology. Please see “Risk Factors—Risks Related to Our Intellectual Property” for additional information on the risks associated with our intellectual property strategy and portfolio.

Intellectual Property Relating to iPSC Technology and Platform

As of February 15, 2024, we own over 25 patent families directed to programming the fate of somatic cells ex vivo, including patent applications pending in the U.S. and internationally related to our platform for industrial-scale iPSC generation and applications related to differentiation of iPSCs into specialized cells with therapeutic potential. These patent applications cover our proprietary small molecule-enhanced iPSC platform, including novel reprogramming factors and methods of reprogramming to obtain iPSCs. Our intellectual property portfolio also includes gene editing compositions and methods of genetic engineering, as well as methods of directing the fate of cells to obtain homogenous cell populations in the hematopoietic lineage, including CD34+ cells, T-cells and NK cells. Our proprietary intellectual property enables highly-efficient iPSC derivation, selection, engineering, and clonal expansion while maintaining genomic stability. Any U.S. patents issued from these patent applications are expected to have statutory expiration dates ranging from 2031 to 2043.

Additionally, we have licensed from the Whitehead Institute for Biomedical Research a portfolio of four patent families including issued patents and pending applications broadly applicable to the reprogramming of somatic cells. Our license is exclusive in commercial fields, including for drug discovery and therapeutic purposes. This portfolio covers the generation of human iPSCs from somatic cells and, as of February 15, 2024, includes 21 issued U.S. patents (including U.S. Patents 8,071,369, 7,682,828 and 9,497,943) claiming compositions used in the reprogramming of mammalian somatic cells to a less differentiated state (including to a pluripotent state), and methods of making a cell more susceptible to reprogramming. Specifically, the portfolio includes a composition of matter patent issued in the United States covering a cellular composition comprising a somatic cell having an exogenous nucleic acid that encodes an OCT4 protein. OCT4 is the key pluripotency gene most commonly required for the generation of iPSCs. These issued patents and any U.S. patents that may issue from these pending patent applications are expected to have statutory expiration dates ranging from 2024 to 2029.

We also have exclusive licenses from The Scripps Research Institute to a portfolio of seven patent families relating to compositions and methods for reprogramming mammalian somatic cells, which covers non-genetic and viral-free reprogramming mechanisms, including the use of various small molecule classes and compounds and the introduction of cell-penetrating proteins to reprogram mammalian somatic cells. This portfolio includes issued U.S. patents (including U.S. Patents 8,044,201 and 8,691,573) that provide composition of matter protection for a class of small molecules, including thiazovivin, that is critical for inducing the generation, and maintaining the pluripotency, of iPSCs, and compositions and methods of using the small molecule. Any issued U.S.

patents and any U.S. patents that may issue from patent applications pending in this portfolio are expected to have statutory expiration dates ranging from 2026 to 2031.

We also have exclusively licensed from the J. David Gladstone Institutes (Gladstone) intellectual property covering the generation of iPSCs using CRISPR-mediated gene activation. This approach for inducing pluripotency uses CRISPR to directly target a specific location of the genome and activate endogenous gene expression, and does not rely on established methods of cellular reprogramming that require the transduction of multiple transcription factors. Any U.S. patents that may issue from patent applications pending in the U.S. and internationally in this portfolio are expected to have a statutory expiration date in 2038.

We also have licensed exclusive rights to five families of patent applications from the University of Minnesota. As of February 15, 2024 this portfolio includes over 80 issued patents or pending patent applications in the United States and foreign jurisdictions directed to compositions of NK cells, including adaptive memory NK cells and genetically-engineered NK cells, and therapeutic strategies for the treatment of cancer using these NK cells. These applications also describe methods of enhancing NK cell cytotoxicity by genetically engineering the CD16 Fc receptor in immune cells, including iPSC-derived NK cells, and describe methods of increasing NK cell tumor specificity and cytotoxicity by incorporating CARs on NK cells. Any U.S. patents that may issue from patent applications pending in this portfolio are expected to have statutory expiration dates between 2035 and 2038.

Collectively, this portfolio covers compositions of CAR constructs, compositions of T-cells and NK cells derived from pluripotent cells which are engineered with CARs, methods of engineering pluripotent cell lines, methods of deriving CAR T-cells from CAR expressing pluripotent stem cells, and methods of using CRISPR for producing off-the-shelf T-cell immunotherapies. Any U.S. patents that may issue from patent applications pending in this portfolio are expected to have statutory expiration dates between 2034 and 2038.

In addition, we have licensed exclusive rights from the Max Delbruck Center for Molecular Medicine to intellectual property directed to novel humanized antibody fragments, antigen-binding domains and CAR constructs that uniquely target and specifically bind BCMA. Under the license agreement, we are granted an exclusive license for use in allogeneic engineered pluripotent stem cells. Any patents issuing from patent applications pending in the U.S. and internationally in this portfolio are expected to have statutory expiration dates between 2033 and 2037.

We have also licensed exclusive rights from the Dana-Farber Cancer Institute (DFCI) to certain intellectual property covering novel antibody fragments that uniquely and specifically bind the alpha-3 domain of MICA/B. We are granted exclusive worldwide rights for use in iPSC-derived cellular therapeutics for the treatment of human disease under the license agreement. Any patents that may issue from patent applications pending in this portfolio are expected to have statutory expiration dates in 2038.

Additionally, we have licensed exclusive rights from BCM to intellectual property covering the composition and use of a novel ADR that selectively targets activated T-cells to protect engineered allogeneic cell products expressing the ADR from elimination in the host immune system. Under the license agreement with BCM, we are granted exclusive worldwide rights to use ADR in the field of iPSC-derived cell products, including T-cells and NK cells derived from iPSCs engineered with ADRs. As of February 15, 2024, the portfolio includes one issued patent and 14 pending applications broadly applicable to making and using ADR-expressing effector cells, including T-cells and NK cells differentiated from iPSCs engineered with ADRs. We expect U.S. patents related to this technology to have statutory expiration dates starting in 2039.

Intellectual Property Relating to CRISPR Engineering

In August 2019, we entered into a license agreement with Inscripta, Inc. Under the license agreement, we obtained a royalty-free, irrevocable license to a patent portfolio covering the composition, production and use of MAD7, a novel gene-editing CRISPR endonuclease from the Eubacterium rectale genome. The intellectual property includes issued patents and pending applications broadly applicable to MAD7 and the editing of mammalian cells. Our license covers the making and using of MAD7 for editing iPSCs, making master engineered iPSC lines and using master engineered iPSC lines to manufacture human therapeutic products. We expect U.S. patents related to this work to have statutory expiration dates starting in 2037.

Intellectual Property Relating to the Programming of Hematopoietic Cells

As of February 15, 2024, we own 16 families of U.S. and foreign patents and pending patent applications covering our cell programming technology and compositions of programmed cellular immunotherapies. This portfolio includes over 150 issued patents or pending patent applications relating to methods of programming the biological properties and therapeutic function of cells ex vivo, and the resulting therapeutic compositions of hematopoietic and immune cells. Patents and patent applications in this portfolio include claims covering (i) therapeutic compositions of hematopoietic and immune cells, including T-cells, NK cells, and CD34+ cells, that

have been programmed ex vivo with one or more agents to optimize their therapeutic function for application in oncology and immune diseases and (ii) methods of programming cells including by the activation or inhibition of therapeutically-relevant genes and cell-surface proteins, such as those involved in the homing, proliferation and survival of hematopoietic cells or those involved in the persistence, proliferation and reactivity of immune cells. Any U.S. patents within this portfolio that have issued or may yet issue from pending patent applications will have statutory expiration dates between 2032 and 2044.

Additionally, upon the achievement of specific regulatory and commercial milestones, we are required to make payments to TSRI of up to approximately $1.8 million under each of the TSRI License Agreements. We will also be required to pay TSRI royalties at percentage rates ranging in the low- to mid-single digits on net sales of licensed products. In the event that we sublicense the patent rights, TSRI is also entitled to receive a percentage of the sublicensing income received by us.

Under the TSRI License Agreements, we are obligated to use commercially reasonable efforts to meet the development benchmarks set out in development plans under each of the TSRI License Agreements, or otherwise expend a minimum specified amount per year for product development. TSRI has the right to terminate any TSRI License Agreement if we fail to perform our obligations under the applicable agreement, including failure to meet any development benchmark or to use commercially reasonable efforts and due diligence to develop a licensed product, or if we otherwise breach the agreement, challenge the licensed patent rights, are convicted of a felony involving the development or commercialization of a licensed product or process, or become insolvent. We may terminate any of our TSRI License Agreements by providing ninety days’ written notice to TSRI. Each TSRI License Agreement otherwise terminates upon the termination of royalty obligations under such agreement.

Dana-Farber Cancer Institute (DFCI)

In April 2020, we entered into a license agreement with the DFCI for rights relating to novel antibody fragments that uniquely and specifically bind the alpha-3 domain of MICA/B. Under our license agreement with DFCI, we acquired an exclusive royalty-bearing, sublicensable, worldwide license to make, use and sell products covered by the licensed patent rights in the field of iPSC-derived cellular therapeutics for the treatment of human disease, and a non-exclusive royalty-bearing, sublicensable, worldwide license to make, use and sell products covered by the licensed patent rights in the field of cellular therapeutics for the treatment of human disease. DFCI retains the right to practice and to license to other academic, government and non-profit institutes to practice the patent rights for research, teaching and education purposes, as well as to license third parties to practice the patents rights to make or sell research reagents or other research tools solely for use in research. Our licenses are also subject to pre-existing rights of the U.S. government.

Under the terms of the license agreement, we are required to make minimum annual payments to DFCI throughout the term of the agreement. We also are required to make development, commercialization and sales milestones payments to DFCI of up to $25 million per licensed product. If commercial sales of a licensed product commence, we will pay DFCI royalties at percentage rates

ranging in the low single digits on net sales of licensed products in countries where such product is protected by licensed patent rights. Our obligation to pay royalties continues on a country-by-country basis until the expiration of all licensed patent rights covering licensed products in such country, and our royalty payments will be reduced by other payments we are required to make to third parties in certain circumstances until a minimum royalty percentage has been reached. In the event that we sublicense the patent rights, DFCI is also entitled to receive a percentage of the sublicensing income received by us.

Under our agreement with DFCI, we are obligated to use reasonable efforts to develop and bring one or more licensed products to the marketplace through a program of development, production and distribution, including by meeting certain diligence benchmarks with respect to exclusively licensed products.

The agreement will continue until the expiration of the last to expire licensed patent. DFCI may terminate the agreement for cause, including if we default in the performance of any of our obligations and fail to cure the default within a specified grace period, if an officer of ours (or of an affiliate or sublicensee) is convicted of a felony related to the manufacture, use, sale or important or a licensed product, if we cease to carry out our business or become bankrupt or insolvent, and if we institute a proceeding to challenge the patent rights. DFCI may also terminate our exclusive license if we fail to materially comply with our diligence obligations. We may terminate the agreement for any reason in its entirety or on a product-by-product or country-by-country basis upon prior written notice to DFCI and payment of all amounts due to DFCI through the date of termination.

Baylor College of Medicine (BCM)

In April 2020, we entered into a license agreement with BCM for rights pertaining to a novel ADR that selectively targets activated T-cells to protect engineered allogeneic effector cells expressing the ADR from elimination in the host immune system. Under our agreement, we obtained an exclusive royalty-bearing, sublicensable, worldwide license to make, use and sell products covered by the licensed patent rights in the field of iPSC-derived cell products, including T-cells and NK cells derived from iPSCs engineered with ADRs. BCM retains the right to practice and license to other academic, government and research institutes for non-commercial research purposes. Our licenses are also subject to pre-existing rights of the U.S. government.

Under the terms of the license agreement, we are obligated to make a minimum annual royalty payment to BCM starting in 2024. We are also required to make development and regulatory milestone payments to BCM for the first three (3) distinct licensed products, where the milestone payments total up to $7 million for the first licensed product, and are reduced by fifty percent (50%) for each of the second and third licensed products. If commercial sales of a licensed product commence, we will pay BCM a low single-digit percentage royalty on net sales of licensed products in countries where the product is protected by licensed patent rights. Our obligation to pay royalties continues on a country-by-country basis until the expiration of all licensed patent rights in that country, with possible reductions for payments that we are required to make to third parties. In the event that we sublicense the patent rights, BCM is entitled to receive a percentage of our sublicensing income.

Under the license agreement, we are obligated to use reasonable efforts to develop and introduce licensed products to the commercial market including by meeting certain diligence timelines. These timelines are extendable by us for one year upon a one-time payment, subject to BCM’s discretion for further extensions.

The license agreement remains in effect until the expiration of the last to expire licensed patent. BCM has the right to terminate the agreement if we materially default in the performance of any terms and fail to correct the default within a specified grace period after BCM’s written notice. Termination by BCM is also possible if we are subject to insolvency or similar proceedings, assignment of all or substantially all of our assets for the benefit of creditors, or the appointment of a trustee, in each case that are not dismissed, stayed or suspended within thirty (30) days following such events. We retain the right to terminate the agreement for any cause, upon prior written notice to BCM and payment of all amounts due to BCM under the agreement.

Manufacturing

Off-the-shelf, Multiplexed-engineered, iPSC-derived Cellular Immunotherapies

The manufacture of our off-the-shelf, multiplexed-engineered, iPSC-derived CAR NK cell and CAR T-cell product candidates involves a three-stage process:

As part of our manufacturing process, we endeavor to utilize current Good Manufacturing Process (cGMP) grade materials and reagents, if commercially available; however, certain critical materials and reagents are currently qualified for research use only. Additionally, we obtain key components required for the manufacture of our iPSC-derived cell product candidates from third-party manufacturers and suppliers, which include, in some instances, sole source manufacturers and suppliers. We do not currently have long-term commitments or supply agreements in place to obtain certain key components used in the manufacture of our iPSC-derived cell product candidates.

We currently manufacture our iPSC-derived cell product candidates for use in research, preclinical development, and clinical development. We operate two cGMP-compliant manufacturing facilities for the clinical production of our iPSC-derived cell product candidates. Both of our manufacturing facilities are located in San Diego, California, and are custom designed for the production of off-the-shelf cell product candidates using clonal master iPSC lines as the starting cell source. Each of these state-of-the-art facilities have been commissioned and qualified, and we have been issued drug manufacturing licenses for each facility by the State of California, Department of Health Services, Food and Drug Branch. With the extension of manufacturing to our corporate headquarters in 2022, we are positioned to support manufacturing and production of our product candidates for all phases of clinical development as well as initial commercialization.

We also contract with third parties, including medical center cell therapy facilities and contract manufacturing organizations (CMOs), for the conduct of some of the activities required to manufacture our iPSC-derived cell product candidates for use in clinical investigation. We expect that we will continue to contract with third parties, including medical center cell therapy facilities and CMOs, for the conduct of certain of the activities required to manufacture our iPSC-derived cell product candidates.

Marketing, Market Access and Sales

We currently intend to commercialize any products that we may successfully develop. We currently have no experience in marketing, market access or selling therapeutic products. We may need to further evaluate and generate evidence beyond what is generated in our clinical programs that would satisfy the needs of payers and healthcare technology assessment (HTA) bodies. To market any of our products independently would also require us to develop a sales force with technical expertise along with establishing commercial infrastructure and capabilities. Our commercial strategy for marketing our product candidates also may include the use of strategic partners, distributors, a contract sales force or the establishment of our own commercial infrastructure. We plan to further evaluate these alternatives as we approach approval for the first of our product candidates.

Government Regulation

In the United States, the FDA regulates biological products under the Federal Food, Drug, and Cosmetic Act (the FDCA) and the Public Health Service Act (the PHS Act) and related regulations. Biological products are also subject to other federal, state, local, and foreign statutes and regulations. The FDA and comparable regulatory agencies in state and local jurisdictions and in foreign countries impose substantial requirements upon the clinical development, manufacture and marketing of biological products. These agencies and other federal, state, local, and foreign entities regulate research and development activities and the testing, manufacture, quality control, safety, effectiveness, packaging, labeling, storage, distribution, record keeping, reporting, approval or licensing, advertising and promotion, and import and export of our products. Failure to comply with the applicable U.S. regulatory requirements at any time during the product development process or after approval may subject an applicant to administrative or judicial sanctions. FDA sanctions include refusal to approve pending applications, withdrawal of an approval or suspension or revocation of a license, clinical hold, warning or untitled letters, voluntary or mandatory product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, refusals of government contracts, mandated corrective advertising or communications with doctors, debarment, restitution, disgorgement of profits, or civil or criminal penalties. In addition, government regulation may delay or prevent marketing of product candidates for a considerable period of time and impose costly procedures upon our activities.

Marketing Approval

The process required by the FDA before biological products may be marketed in the United States generally involves the following:

U.S. Biological Products and Drug Development Process

Before testing any biological product candidate in humans, nonclinical tests, including laboratory evaluations and animal studies to assess the potential safety and activity of the product candidate, are conducted. The conduct of the nonclinical tests must comply with federal regulations and requirements including GLPs.

Prior to commencing the first clinical trial, the trial sponsor must submit the results of the nonclinical tests, together with manufacturing information, analytical data, any available clinical data or literature and a proposed clinical protocol, to the FDA as part of an initial IND application. Some nonclinical testing may continue even after the IND application is submitted. The IND application automatically becomes effective 30 days after receipt by the FDA unless the FDA, within the 30-day time period, raises concerns or questions about the conduct of the clinical trial and places the trial on a clinical hold. In such case, the sponsor of the IND application must resolve any outstanding concerns with the FDA before the clinical trial may begin. The FDA also may impose a clinical hold on ongoing clinical trials due to safety concerns or non-compliance. If a clinical hold is imposed, a trial may not recommence without FDA authorization and then only under terms authorized by the FDA. A clinical hold may either be a full clinical hold or a partial clinical hold that would limit a trial, for example, to certain doses or for a certain length of time or to a certain number of subjects. Further, an independent IRB for each site proposing to conduct the clinical trial must review and approve the plan for any clinical trial before it commences at that site. An IRB is charged with protecting the welfare and rights of study subjects and considers such items as whether the risks to individuals participating in the clinical trials are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the form and content of the informed consent that must be signed by each clinical trial subject or his or her legal representative and must monitor the clinical trial until completed. Some trials are overseen by an independent group of qualified experts organized by the trial sponsor, known as a data safety monitoring board or committee. This group provides authorization as to whether or not a trial may move forward at designated check points based on access that only the group maintains to available data from the trial and may recommend halting the clinical trial if it determines that there is an unacceptable safety risk for subjects or other grounds, such as no demonstration of efficacy.

Clinical trials involve the administration of the product candidate to healthy volunteers or patients under the supervision of qualified investigators, generally physicians not employed by or under the trial sponsor’s control. Clinical trials are conducted under protocols detailing, among other things, the objectives of the clinical trial, dosing procedures, subject selection and exclusion criteria, and the parameters to be used to monitor subject safety, including rules that assure a clinical trial will be stopped if certain adverse events occur. Each protocol and any amendments to the protocol must be submitted to the FDA and to the IRB. Information about

certain clinical studies must be submitted with specific timeframes to the National Institutes of Health for public dissemination at www.clinicaltrials.gov.

For purposes of BLA approval, human clinical trials are typically conducted in three sequential phases that may overlap:

During all phases of clinical development, regulatory agencies require extensive monitoring and auditing of all clinical activities, clinical data, and clinical trial investigators. Annual progress reports detailing the results of the clinical trials must be submitted to the FDA. Within 15 calendar days after the sponsor determines that the information qualifies for reporting, written IND safety reports must be submitted to the FDA and the investigators for serious and unexpected adverse events; any findings from other studies, tests in laboratory animals or in vitro testing that suggest a significant risk for human subjects; or any clinically important increase in the rate of a serious suspected adverse reaction over that listed in the protocol or investigator brochure. The sponsor also must notify the FDA of any unexpected fatal or life-threatening suspected adverse reaction within seven calendar days after the sponsor’s initial receipt of the information.

Regulatory authorities, a data safety monitoring board or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the participants are being exposed to an unacceptable health risk. Similarly, an IRB can suspend or terminate approval of a clinical trial at its institution if the trial is not being conducted in accordance with the IRB’s requirements or if the investigated product has been associated with unexpected serious harm to patients, and the trial may not recommence without the IRB’s authorization.

Typically, if a product is intended to treat a chronic disease, safety and efficacy data must be gathered over an extended period of time, which can range from six months to three years or more.

Concurrently with clinical trials, companies usually complete additional animal studies and must also develop additional information about the physical characteristics of the investigational product and finalize a process for manufacturing the product in commercial quantities in accordance with cGMP requirements. To help reduce the risk of the introduction of adventitious agents with the use of biological products, the PHS Act emphasizes the importance of manufacturing control for products whose attributes cannot be precisely defined. The manufacturing process must be capable of consistently producing quality batches of the product candidate and, among other things, the sponsor must develop methods for testing the identity, strength, quality, potency, and purity of the final biological product. Additionally, appropriate packaging must be selected and tested and stability studies must be conducted to demonstrate that the biological product candidate does not undergo unacceptable deterioration over its shelf life.

A drug being studied in clinical trials may be made available to individual patients in certain circumstances. Pursuant to the 21st Century Cures Act (the Cures Act), as amended, the manufacturer of an investigational drug for a serious disease or condition is required to make available, such as by posting on its website, its policy on evaluating and responding to requests for individual patient access to such investigational drug. This requirement applies on the earlier of the first initiation of a Phase 2 or Phase 3 trial of the investigational drug, or as applicable, 15 days after the drug receives a designation as a breakthrough therapy, fast track product, or RMAT. Further, the Right to Try Act of 2017 among other things, provides a federal framework for certain patients to request access to certain IND products that have completed a Phase 1 clinical trial and that are undergoing investigation for FDA approval. There is no obligation for a pharmaceutical manufacturer to make its drug products available to eligible patients as a result of the Right to Try

Act. We review each individual request for access through the Cures Act, the Right to Try Act and similar state laws, and may or may not provide access depending upon the facts of each request.

U.S. Review and Approval Processes

In order to obtain approval to market a biological product in the United States, a BLA must be submitted to the FDA that provides data establishing to the FDA’s satisfaction the safety, purity and potency of the investigational product for the proposed indication. A BLA includes all data available from nonclinical studies and clinical trials, together with detailed information relating to the product’s manufacture and composition, and proposed labeling.

Under the Prescription Drug User Fee Act (PDUFA), as amended, each BLA must be accompanied by a user fee. PDUFA also imposes an annual prescription drug product program fee for biologics and drugs. The FDA adjusts the PDUFA user fees on an annual basis. Fee waivers or reductions are available in certain circumstances, including a waiver of the application fee for the first application filed by a small business having fewer than 500 employees. Additionally, no user fees are assessed on BLAs for products designated as orphan drugs, unless the product also includes a non-orphan indication.

The FDA has 60 days from its receipt of a BLA to determine whether the application will be accepted for filing based on the agency’s threshold determination that the application is sufficiently complete to permit substantive review. The FDA may refuse to file any BLA that it deems incomplete or not properly reviewable at the time of submission and may request additional information. In this event, the BLA must be resubmitted with the additional information. The resubmitted application also is subject to review before the FDA accepts it for filing. After the BLA submission is accepted for filing, the FDA reviews the BLA to determine, among other things, whether the proposed product is safe and effective for its intended use, and has an acceptable purity profile, and whether the product is being manufactured in accordance with cGMPs to assure and preserve the product’s identity, safety, strength, quality, potency, and purity, and for a biological product, whether it meets the biological product standards. The FDA may refer applications for novel products or products that present difficult questions of safety or efficacy to an advisory committee, typically comprised of clinicians and other experts, for evaluation and a recommendation as to whether the application should be approved and, if so, under what conditions. The FDA is not bound by the recommendations of an advisory committee, but it considers such recommendations carefully when making decisions.

Before approving a BLA, the FDA will inspect the facilities at which the product is manufactured. The FDA will not approve the product unless it determines that the manufacturing processes and facilities are in compliance with cGMP requirements and adequate to assure consistent production of the product within required specifications. For a human cellular or tissue product, the FDA also will not approve the product if the manufacturer is not in compliance with cGTPs. FDA regulations also require tissue establishments to register and list their human cells, tissues, and cellular and tissue based products (HCT/Ps) with the FDA and, when applicable, to evaluate donors through screening and testing. Additionally, before approving a BLA, the FDA may inspect clinical sites to assure that the clinical trials were conducted in compliance with IND study requirements and GCPs. If the FDA determines the manufacturing process or manufacturing facilities are not acceptable, it typically will outline the deficiencies and often will require the facility to take corrective action and provide documentation evidencing the implementation of such corrective action, which may delay further review of the application. If the FDA finds that a clinical site did not conduct the clinical trial in accordance with GCPs, the FDA may determine the data generated by the site should be excluded from the primary efficacy analyses provided in the BLA, and request additional testing or data. Additionally, the FDA ultimately may still decide that the application does not satisfy the regulatory criteria for approval.

The FDA also has authority to require a Risk Evaluation and Mitigation Strategy (REMS) from manufacturers to ensure that the benefits of a biological product outweigh its risks. A sponsor may also voluntarily propose a REMS as part of the BLA submission. The need for a REMS is determined as part of the review of the BLA. Based on statutory standards, elements of a REMS may include “dear doctor letters,” a medication guide, more elaborate targeted educational programs, and in some cases restrictions on distribution. These elements are negotiated as part of the BLA approval, and in some cases may delay the approval date. Once adopted, REMS are subject to periodic assessment and modification.

After the FDA completes its initial review of a BLA, it will communicate to the sponsor that the biological product will either be approved, or it will issue a complete response letter to communicate that the BLA will not be approved in its current form. The complete response letter usually describes all of the specific deficiencies in the BLA identified by the FDA. The deficiencies identified may be minor, for example, requiring labeling changes, or major, for example, requiring additional clinical trials. Additionally, the complete response letter may include recommended actions that the applicant might take to place the application in a condition for approval. If a complete response letter is issued, the applicant may either resubmit the BLA to address all of the deficiencies identified in the letter, or withdraw the application, or request a hearing.

One of the performance goals of the FDA under PDUFA is to review 90% of standard BLAs in 10 months and 90% of priority BLAs in six months, whereupon a review decision is to be made. The FDA does not always meet its PDUFA goal dates for standard and priority BLAs and its review goals are subject to change from time to time. The review process and the PDUFA goal data may be extended by three months if the FDA requests or the BLA applicant otherwise provides additional information or clarification regarding information already provided in the submission within the last three months before the PDUFA goal date.

Even if a product candidate receives regulatory approval, the approval may be limited to specific disease states, patient populations and dosages, or the indications for use may otherwise be limited. Further, the FDA may require that certain contraindications, warnings, or precautions be included in the product labeling. The FDA may impose restrictions and conditions on product distribution, prescribing, or dispensing in the form of a risk management plan, or otherwise limit the scope of any approval. In addition, the FDA may require Phase 4 post-marketing clinical trials and testing and surveillance programs to monitor the safety of approved products that have been commercialized. Further, even after regulatory approval is obtained, later discovery of previously unknown problems with a product may result in the imposition of new restrictions on the product or complete withdrawal of the product from the market.

Post-Approval Requirements

Products manufactured or distributed pursuant to FDA approvals are subject to continuing regulation by the FDA, including, among other things, requirements relating to monitoring, record-keeping, advertising and promotion, reporting of adverse experiences, and limitations on industry-sponsored scientific and educational activities. Further, if there are any modifications to the drug or biologic, including changes in indications, labeling or manufacturing processes or facilities, the applicant may be required to submit and obtain FDA approval of a new BLA or a BLA supplement, which may require the development of additional data or preclinical studies and clinical trials.

FDA regulations require that approved products be manufactured in specific approved facilities and in accordance with cGMP regulations which require, among other things, quality control and quality assurance, the maintenance of records and documentation, and the obligation to investigate and correct any deviations from cGMP. Manufacturers and other entities involved in the manufacture and distribution of approved drugs or biologics, and those supplying products, ingredients, and components of them, are required to register their establishments with the FDA and certain state agencies, and are subject to periodic announced and unannounced inspections by the FDA and certain state agencies for compliance with cGMP requirements and other regulatory requirements. Accordingly, manufacturers must continue to expend time, money and effort in the area of production and quality control to maintain cGMP compliance. The discovery of violative conditions, including failure to conform to cGMP regulations, could result in enforcement actions.

The FDA strictly regulates marketing, labeling, advertising and promotion of products that are placed on the market. Drugs may be promoted only for the approved indications and in accordance with the provisions of the approved label. The FDA does not regulate behavior of physicians in their choice of treatments and physicians may legally prescribe available products for uses that are not described in the product’s labeling and that differ from those approved by the FDA. However, the FDA does restrict an applicant’s communications on the subject of off-label use of their products. The FDA and other agencies actively enforce the laws prohibiting the marketing and promotion of off-label uses, and a company that is found to have improperly marketed or promoted off-label use may be subject to significant liability, including criminal and civil penalties under the FDCA and False Claims Act, exclusion from participation in federal healthcare programs, and mandatory compliance programs.

The FDA also may require post-marketing testing, known as Phase 4 testing, and surveillance to monitor the effects of an approved product. Discovery of previously unknown problems with a product or the failure to comply with applicable FDA requirements can have negative consequences, including adverse publicity, restrictions on a product, and judicial or administrative enforcement.

Expedited Development and Review Programs

The FDA is authorized to designate certain products for expedited review if they demonstrate the potential to address an unmet medical need in the treatment of a serious or life-threatening disease or condition for which there is no effective treatment. These programs are referred to as fast track designation, priority review, accelerated approval, breakthrough therapy designation, and regenerative advanced therapy designation.

Fast Track Designation. The FDA may grant “fast track” status to product candidates that are intended to treat serious or life-threatening diseases or conditions and demonstrate the potential to address an unmet medical need for the condition. Fast track is a process designed to facilitate the development and expedite the review of such product candidates by providing, among other things, more frequent meetings with the FDA to discuss the product candidate’s development plan and rolling review, which allows submission of individually completed sections of an BLA for FDA review before the entire submission is completed. Fast track designation applies to the combination of the product and the specific indication for which it is being studied. The sponsor of a product candidate may request the FDA to designate the product as a fast track product at any time during clinical development. Fast track status does not ensure that a product will be developed more quickly or receive FDA approval. In addition, the fast track designation may be withdrawn by the FDA if the FDA believes that the designation is no longer supported by data emerging in the clinical trial process, or if the designated drug development program is no longer being pursued.

Priority Review. The FDA may give a priority review designation to a product candidate if it has the potential to provide safe and effective therapy where no satisfactory alternative therapy exists or to provide a significant improvement in the treatment, diagnosis or prevention of a disease compared to marketed products. Priority review is intended to reduce the time it takes for the FDA to review a BLA, with the goal to take action on the application within six months from when the application is filed, compared to ten months for a standard review. The FDA will attempt to direct additional resources to the evaluation of an application for a biological product or drug designated for priority review in an effort to facilitate the review.

Accelerated Approval. Additionally, a product may be eligible for accelerated approval. Drug or biological products studied for their safety and effectiveness in treating serious or life-threatening illnesses and that provide meaningful therapeutic benefit over existing treatments may receive accelerated approval, which means that they may be approved on the basis of adequate and well-controlled clinical trials establishing that the product has an effect on a surrogate endpoint that is reasonably likely to predict a clinical benefit, or on the basis of an effect on a clinical endpoint that can be measured earlier than irreversible morbidity or mortality, that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit, taking into account the severity, rarity or prevalence of the condition and the availability or lack of alternative treatments. As a condition of approval, the FDA may require that a sponsor of a biological product or drug receiving accelerated approval perform adequate and well-controlled post-marketing clinical trials with due diligence and, under the Food and Drug Omnibus Reform Act of 2022 (FDORA), the FDA is now permitted to require, as appropriate, that such trials be underway prior to approval or within a specific time period after the date of approval for a product granted accelerated approval. In addition, the FDA currently requires, unless otherwise informed by the agency, pre-approval of promotional materials for products being considered for accelerated approval. Under FDORA, the FDA has increased authority for expedited procedures to withdraw approval of a drug or indication approved under accelerated approval if, for example, the confirmatory trial fails to verify the predicted clinical benefit of the product.

Breakthrough Therapy Designation. A product candidate intended to treat a serious or life-threatening disease or condition may also be eligible for breakthrough therapy designation if preliminary clinical evidence indicates that it may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints. If so designated, the FDA will expedite the development and review of the product candidate’s marketing application, including by meeting with, and providing advice to, the sponsor throughout the product candidate’s development, and taking steps to facilitate an efficient review of the development program and to ensure that the design of the clinical trials is as efficient as practicable.

RMAT Designation. As part of the Cures Act, Congress amended the FDCA to create an accelerated approval program for regenerative advanced therapies. To qualify for this program, and be granted regenerative advanced medicine therapy (RMAT) designation, a product must be a cell therapy, therapeutic tissue engineering product, human cell and tissue product, or a combination of such products, and not a product solely regulated as a human cell and tissue product. This program is intended to facilitate efficient development and expedite review of regenerative advanced therapies, which are intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition and preliminary clinical evidence must indicate that the product candidate has the potential to address an unmet need for such disease or condition. A BLA for a product candidate that has received RMAT designation may be eligible for priority review or accelerated approval through (1) surrogate or intermediate endpoints reasonably likely to predict long-term clinical benefit or (2) reliance upon data obtained from a meaningful number of sites. Benefits of such designation also include early interactions with FDA to discuss any potential surrogate or intermediate endpoint to be used to support accelerated approval. A designated RMAT product candidate that is granted accelerated approval and is subject to post approval requirements may fulfill such requirements through the submission of clinical evidence, clinical studies, patient registries, or other sources of real world evidence, such as electronic health records; the collection of larger confirmatory data sets; or post approval monitoring of all patients treated with such therapy prior to its approval.

Designated Platform Technology Status. Under FDORA, a platform technology incorporated within or utilized by a drug or biological product is eligible for designation as a designated platform technology if (1) the platform technology is incorporated in, or utilized by, a drug approved under a BLA or NDA; (2) preliminary evidence submitted by the sponsor of the approved or licensed drug, or a sponsor that has been granted a right of reference to data submitted in the application for such drug, demonstrates that the platform technology has the potential to be incorporated in, or utilized by, more than one drug without an adverse effect on quality, manufacturing, or safety; and (3) data or information submitted by the applicable person indicates that incorporation or utilization of the platform technology has a reasonable likelihood to bring significant efficiencies to the drug development or manufacturing process and to the review process. A sponsor may request the FDA to designate a platform technology as a designated platform technology concurrently with, or at any time after, submission of an IND application for a drug that incorporates or utilizes the platform technology that is the subject of the request. If so designated, the FDA may expedite the development and review of any subsequent original BLA for a drug that uses or incorporates the platform technology. Designated platform technology status does not ensure that a drug will be developed more quickly or receive FDA approval. In addition, the FDA may revoke a designation if the FDA determines that a designated platform technology no longer meets the criteria for such designation.

RTOR. The FDA may review applications for oncology products under Real-Time Oncology Review (RTOR) established by the FDA’s Oncology Center of Excellence. RTOR, which allows an applicant to pre-submit components of the application to allow the FDA to review clinical data before the complete filing is submitted, aims to explore a more efficient review process to ensure that safe

and effective treatments are available to patients as early as possible, while maintaining and improving review quality. Products considered for review under RTOR must, among other things, be likely to demonstrate substantial improvements on a clinically relevant endpoint(s) over available therapy, and must have easily interpreted endpoints. In addition, no aspect of the application should be likely to require a longer review time, such as, for example, a requirement for a REMS. To determine eligibility for RTOR, the FDA requires top-line efficacy and safety results from an applicant’s pivotal clinical trial(s), as well as completion of database lock for the clinical trial(s). The FDA will generally make a decision regarding acceptance into RTOR within twenty (20) business days of receipt of the request from the applicant. If an applicant is not accepted into RTOR, the applicant will follow routine application submission procedures.

Fast Track designation, priority review, accelerated approval, breakthrough therapy designation, RMAT designation, designated platform technology status, and RTOR do not change the standards for approval but may expedite the development or approval process. Moreover, even if a product candidate or platform technology qualifies for one or more of these programs, the FDA may later decide that the product candidate or platform technology no longer meets the conditions for qualification or decide that the time period for FDA review or approval will not be shortened.

U.S. Patent Term Restoration and Marketing Exclusivity

Under certain circumstances, U.S. patents may be eligible for limited patent term extension under the Drug Price Competition and Patent Term Restoration Act of 1984, commonly referred to as the Hatch-Waxman Amendments. Patent term restoration can compensate for time lost during product development and the regulatory review process by returning up to five years of patent life for a patent that covers a new product or its use. However, patent term restoration cannot extend the remaining term of a patent beyond a total of 14 years from the product’s approval date. The period of patent term restoration is generally one-half the time between the effective date of an IND application (falling after issuance of the patent) and the submission date of a BLA, plus the time between the submission date of the BLA and the approval of that application, provided the sponsor acted with diligence. Only one patent applicable to an approved product is eligible for the extension and the application for the extension must be submitted prior to the expiration of the patent. The application for patent term extension is subject to approval by the U.S. Patent and Trademark Office in consultation with the FDA. A patent term extension is only available when the FDA approves a biological product or drug for the first time.

With the Hatch-Waxman Amendments, Congress authorized the FDA to approve generic drugs that are the same as drugs previously approved by the FDA under the NDA provisions of the FDCA. To obtain approval of a generic drug, an applicant must submit to the agency an abbreviated new drug application (ANDA) which relies on the preclinical and clinical testing previously conducted for a drug approved under an NDA, known as the reference listed drug (RLD). For the ANDA to be approved, the FDA must find that the generic version is identical to the RLD with respect to the active ingredients, the route of administration, the dosage form, and the strength of the drug. The FDA must also determine that the generic drug is bioequivalent to the innovator drug.

An abbreviated approval pathway for biological products shown to be biosimilar to, or interchangeable with, an FDA-licensed reference biological product was created by the Biologics Price Competition and Innovation Act of 2009, which was part of the Patient Protection and Affordable Care Act of 2010 (ACA). This amendment to the PHS Act attempts to minimize duplicative testing. Biosimilarity, which requires that there be no clinically meaningful differences between the biological product and the reference product in terms of safety, purity, and potency, can be shown through analytical studies, animal studies, and a clinical trial or trials. Interchangeability requires that a biological product is biosimilar to the reference biological product and the product must demonstrate that it can be expected to produce the same clinical results as the reference product and, for products administered multiple times, the product and the reference product may be switched after one has been previously administered without increasing safety risks or risks of diminished efficacy relative to exclusive use of the reference biological product.

A reference biological product is granted twelve years of exclusivity from the time of first licensure of the reference product. The first biological product submitted under the abbreviated approval pathway that is determined to be interchangeable with the reference product has exclusivity against other biologics submitting under the abbreviated approval pathway for the lesser of (i) one year after the first commercial marketing, (ii) 18 months after approval if there is no legal challenge, (iii) 18 months after the resolution in the applicant’s favor of a lawsuit challenging the biologic’s patents if an application has been submitted, or (iv) 42 months after the application has been approved if a lawsuit is ongoing within the 42-month period.

A biological product or drug can obtain pediatric market exclusivity in the United States. Pediatric exclusivity, if granted, adds six months to existing exclusivity periods for all formulations, dosage forms, and indications of the active moiety or the biological period and, for drugs, patent terms. This six-month exclusivity, which runs from the end of other exclusivity protection or, for drugs, patent term, may be granted based on the voluntary completion of a pediatric study in accordance with an FDA-issued “Written Request” for such a study provided that at the time pediatric exclusivity is granted there is not less than nine months of term remaining.

Orphan Drug Designation and Exclusivity

Under the Orphan Drug Act, the FDA may grant orphan drug designation to biological products and drugs intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States, or more than 200,000 individuals in the United States and for which there is no reasonable expectation that the cost of developing and making a biological product or drug in the United States for this type of disease or condition will be recovered from sales of the product. Orphan drug designation must be requested before submitting a BLA. After the FDA grants orphan drug designation, the identity of the applicant, the name of the therapeutic agent and its designated orphan use are disclosed publicly by the FDA. Orphan drug designation does not convey any advantage in, or shorten the duration of, the regulatory review and approval process.

If a biological product or drug that receives orphan drug designation is the first such product approved by FDA for the orphan indication, it receives orphan product exclusivity, which for seven years prohibits the FDA from approving another application to market the same product for the same indication. Orphan product exclusivity will not bar approval of another product under certain circumstances, including if the new product is shown to be clinically superior to the approved product on the basis of greater efficacy or safety or a demonstration that the new product otherwise makes a major contribution to patient care. More than one product may also be approved by the FDA for the same orphan indication or disease as long as the products are different. If a biological product or drug designated as an orphan product receives marketing approval for an indication broader than what is designated, it may not be entitled to orphan product exclusivity. Orphan drug status in the European Union has similar, but not identical, benefits.

Pediatric Research Equity Act

Under the Pediatric Research Equity Act (PREA), as amended, a BLA or supplement must contain data to assess the safety and effectiveness of the biological product or drug for the claimed indications in all relevant pediatric subpopulations and to support dosing and administration for each pediatric subpopulation for which the product is safe and effective. The intent of the PREA is to compel sponsors whose products have pediatric applicability to study those products in pediatric populations. The FDCA requires manufacturers of biological products and drugs that include a new active ingredient, new indication, new dosage form, new dosing regimen or new route of administration to submit a pediatric study plan to the FDA as part of the IND application. The plan must be submitted not later than 60 days after the end-of-Phase 2 meeting with the FDA; or if there is no such meeting, before the initiation of any Phase 3 trials or a combined Phase 2 and Phase 3 trial; or if no such trial will be conducted, no later than 210 days before submitting a marketing application or supplement. The FDA may grant deferrals for submission of data or full or partial waivers. Generally, the PREA does not apply to any biological product or drug for an indication for which orphan designation has been granted.

Coverage and Reimbursement

Sales of our products, when and if approved, will depend, in part, on the extent to which our products will be covered by third-party payors, such as government health programs, commercial insurance and managed healthcare organizations. In the United States, no uniform policy of coverage and reimbursement for drug or biological products exists. Accordingly, decisions regarding the extent of coverage and amount of reimbursement to be provided for any of our products will be made on a payor-by-payor basis. Additionally, coverage determinations often require generating additional evidence related, for example, to the relative costs and benefits of new therapies versus standard of care – which goes beyond the data able to be generated within our clinical programs. Patients are unlikely to use our products unless coverage is provided and reimbursement is adequate to cover a significant portion of their cost.

In the United States, for example, principal decisions about reimbursement for new products are typically made by the Centers for Medicare & Medicaid Services (CMS), which decides whether and to what extent a new product will be covered and reimbursed under Medicare. Private third-party payors often follow CMS’s decisions regarding coverage and reimbursement to a substantial

degree. However, one third-party payor’s determination to provide coverage for a product candidate does not assure that other payors will also provide coverage for the product candidate. Further, no uniform policy for coverage and reimbursement exists in the United States, and coverage and reimbursement can differ significantly from payor to payor. As a result, coverage determination is often a time-consuming and costly process that will require us to provide scientific and clinical support for the use of our products to each payor separately, with no assurance that coverage and adequate reimbursement will be obtained. Further, coverage policies and third-party payor reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained, less favorable coverage policies and reimbursement rates may be implemented in the future.

The U.S. government, state legislatures and foreign governments have shown significant interest in implementing cost containment programs to limit the growth of government-paid health care costs, including price-controls, restrictions on reimbursement and requirements for substitution of biosimilars for branded prescription drugs. Net prices for drugs may be reduced by mandatory discounts or rebates required by government healthcare programs or private payors and by any future relaxation of laws that presently restrict imports of drugs from countries where they may be sold at lower prices than in the United States. In addition, many pharmaceutical manufacturers must calculate and report certain price reporting metrics to the government, such as average sales price and best price. Penalties may apply in some cases when such metrics are not submitted accurately and timely. Increasingly, third-party payors are also requiring that drug companies provide them with predetermined discounts from list prices and are challenging the prices charged for medical products. We cannot be sure that reimbursement will be available for any product candidate that we commercialize and, if reimbursement is available, the level of reimbursement.

In some foreign countries, the proposed pricing for a drug must be approved before it may be lawfully marketed. The requirements governing drug pricing vary widely from country to country. For example, the European Union provides options for its Member States to restrict the range of medicinal products for which their national health insurance systems provide reimbursement and to control the prices of medicinal products for human use. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost effectiveness of a particular product candidate to currently available therapies. A Member State may approve a specific price for the medicinal product or it may instead adopt a system of direct or indirect controls on the profitability of the company placing the medicinal product on the market. There can be no assurance that any country that has price controls or reimbursement limitations for pharmaceutical products will allow favorable reimbursement and pricing arrangements for any of our product candidates. Historically, products launched in the European Union do not follow price structures of the United States and generally prices tend to be significantly lower.

Healthcare Reform and Other Regulatory Changes

In the United States and some foreign jurisdictions, there have been, and likely will continue to be, a number of legislative and regulatory changes and proposed changes regarding the healthcare system directed at broadening the availability of healthcare, improving the quality of healthcare, and containing or lowering the cost of healthcare.

For example, in 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act, each as amended, collectively known as the ACA was enacted in the United States. The ACA includes measures that have significantly changed, and are expected to continue to significantly change, the way healthcare is financed by both governmental and private insurers. The ACA contained a number of provisions, including those governing enrollment in federal healthcare programs, reimbursement adjustments and changes to fraud and abuse laws. Among the provisions of the ACA of greatest importance to the pharmaceutical industry are that the ACA:

Other legislative changes have been proposed and adopted in the United States since the Affordable Care Act was enacted include the following:

The costs of prescription pharmaceuticals have also been the subject of considerable discussion in the United States. To date, there have been several recent U.S. congressional inquiries, as well as proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, reduce the costs of drugs under Medicare and reform government program reimbursement methodologies for drug products. President Biden has issued multiple executive orders that have sought to reduce prescription drug costs. In February 2023, HHS also issued a proposal in response to an October 2022 executive order from President Biden that includes a proposed prescription drug pricing model that will test whether targeted Medicare payment adjustments will sufficiently incentivize manufacturers to complete confirmatory trials for drugs approved through FDA’s accelerated approval pathway. Although a number of these and other proposed measures may require authorization through additional legislation to become effective, and the Biden administration may reverse or otherwise change these measures, both the Biden administration and Congress have indicated that they will continue to seek new legislative measures to control drug costs.

At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the ultimate demand for our drugs or put pressure on our drug pricing, which could negatively affect our business, financial condition, results of operations and prospects.

Other Healthcare Laws and Compliance Requirements

Pharmaceutical companies are subject to additional healthcare regulation and enforcement by the federal government and by authorities in the states and foreign jurisdictions in which they conduct their business that may constrain the financial arrangements and relationships through which we research, as well as sell, market and distribute any products for which we obtain marketing authorization. Arrangements with third-party payors and customers can expose pharmaceutical manufactures to broadly applicable fraud and abuse and other healthcare laws and regulations, including, without limitation, the federal Anti-Kickback Statute and the federal False Claims Act (FCA) which may constrain the business or financial arrangements and relationships through which companies research, sell, market and distribute pharmaceutical products. In addition, transparency laws and patient privacy laws can apply to the activities of pharmaceutical manufactures. The applicable federal, state and foreign healthcare laws and regulations that can affect a pharmaceutical company’s operations include without limitation:

The scope and enforcement of each of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulations with respect to certain laws. Federal and state enforcement bodies have recently increased their scrutiny of interactions between healthcare companies and healthcare providers, which has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Prohibitions or restrictions on sales or withdrawal of future marketed products could materially affect our business in an adverse way. Changes in regulations, statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example: (i) changes to our manufacturing arrangements; (ii) additions or modifications to product labeling; (iii) the recall or discontinuation of our products; or (iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect the operation of our business. Ensuring our business arrangements comply with applicable healthcare laws, as well as responding to possible investigations by government authorities, can be time- and resource-consuming and can divert a company’s attention from the business.

The failure to comply with any of these laws or regulatory requirements subjects companies to possible legal or regulatory action. Depending on the circumstances, failure to meet applicable regulatory requirements can result in significant penalties, including civil, criminal and administrative penalties, damages, fines, disgorgement, imprisonment, possible exclusion from participation in federal and state funded healthcare programs, contractual damages and the curtailment or restricting of our operations, as well as additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws. Any action for violation of these laws, even if successfully defended, could cause a pharmaceutical company to incur significant legal expenses and divert management’s attention from the operation of the business.

Regulations Governing Data Collection and the Use, Processing and Cross-Border Transfer of Personal Information

We also may be or may become subject to various state and foreign laws governing the privacy and security of health information, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.

For example, the California Consumer Privacy Act (CCPA), created individual privacy rights for California consumers (as defined in the law) and requires compliance with privacy and security obligations for entities handling personal data of consumers or households. The CCPA requires covered companies to provide certain disclosures to consumers about its data collection, use and sharing practices, and to provide affected California residents with ways to opt out of certain sales or transfers of personal information. The California Privacy Rights Act (CPRA) amended the CCPA and expands consumer privacy rights in California, including by expanding consumers’ rights with respect to certain sensitive personal information and by establishing a state agency vested with the authority to enforce the CCPA. The CPRA also applies to personal information collected about employees, applicants and retirees, as well as that which is collected in a business-to-business capacity. While there is currently an exception in the CCPA for protected health information that is subject to HIPAA, the CCPA may nevertheless impact our business activities. Several other U.S. states have passed or enacted legislation similar to the CCPA, but contain key differences in the scope, application, and enforcement which may complicate compliance efforts.

In addition the EU General Data Protection Regulation (EU GDPR), as well as other national data protection legislation in force in relevant European Economic Area (EEA) Member States, and the UK equivalent of the same (UK GDPR) (collectively referred to as the GDPR in this Annual Report), and UK Data Protection Act 2018 regulates the collection and processing of personal data in the EEA and the United Kingdom (UK). The GDPR covers any business, regardless of its location, that provides goods or services to individuals in the EU/UK or monitors their behavior in the EEA/UK, and, thus, could incorporate any activities we undertake in EEA/UK. The GDPR imposes strict requirements on controllers and processors of personal data, including special protections for “sensitive information,” which includes health and genetic information, obtaining consent of the individuals to whom the personal data relates, having legal bases for processing personal data, providing transparency information to individuals, implementing safeguards to protect the security and confidentiality of personal data, having data processing agreements with third parties who process personal data, responding to individuals’ requests to exercise their data protection rights, reporting personal data breaches to the competent national data protection authority and affected individuals, appointing data protection officers, ensuring certain accountability measures are in place and record keeping. Failure to comply with the requirements of the GDPR and the related national data protection laws of the EEA Member States and the UK, which may deviate slightly from the GDPR, may result in warning letters, mandatory audits and financial penalties, including fines of up to 4% of global revenues, or €20,000,000, (£17.5 million for the UK GDPR), whichever is greater. The GDPR also confers a private right of action on data subjects and consumer associations to lodge complaints with supervisory authorities, seek judicial remedies, and obtain compensation for damages resulting from violations of the GDPR.

The UK’s data protection regime is independent from but currently still aligned to the EU’s data protection regime. However, the UK has announced plans to reform the country’s data protection legal framework in its Data Reform Bill, which will introduce significant changes from the EU GDPR. This may lead to additional compliance costs and could increase our overall risk exposure as we may no longer be able to take a unified approach across the EEA and the UK, and we will need to amend our processes and procedures to align with the new framework.

The GDPR also impose restrictions in relation to the international transfer of personal data from the EEA and UK to other countries in respect of which the European Commission or the UK government has not issued a so-called “adequacy decision” or “ adequacy regulation”, including the US in certain circumstances, unless the parties to the transfer have implemented specific safeguards to protect the transferred personal data, such as the European Commission’s Standard Contractual Clauses for transfers outside of the EEA (SCCs) and a similar transfer mechanism for transfers of personal data outside of the UK, the International Data Transfer Agreement or Addendum (IDTA). Where relying on the SCCs or IDTA for data transfers, exporters are also required to carry out transfer impact assessments to assess the risk of the data transfer on a case-by-case basis, including an analysis of the laws in the destination country. Although the UK is regarded as a third country under the EU’s GDPR, the European Commission (EC) has issued a decision recognizing the UK as providing adequate protection under the EU GDPR and, therefore, transfers of personal data originating in the EEA to the UK remain unrestricted.

In July 2023, the European Commission adopted its adequacy decision for the EU-U.S. Data Privacy Framework (Framework), the successor of the EU-U.S. Privacy Shield framework, which the Court of Justice of the European Union invalidated in 2020. On the basis of the new adequacy decision, personal data can flow safely from the EU to U.S. companies participating in the Framework, without having to put in place additional data protection safeguards. However, the Framework’s validity has already been challenged in court.

Implementing mechanisms to endeavor to ensure compliance with the GDPR and relevant local legislation in EEA Member States and the UK may be onerous and may interrupt or delay our development activities, and adversely affect our business, financial condition, results of operations, and prospects. In addition to the foregoing, a breach of the CCPA, GDPR or other applicable privacy and data protection laws and regulations could result in regulatory investigations, reputational damage, and orders to cease/change our use of data, enforcement notices, or potential civil claims including class action-type litigation.

Other Regulations

We are also subject to numerous federal, state and local laws relating to such matters as safe working conditions, manufacturing practices, environmental protection, fire hazard control, and disposal of hazardous or potentially hazardous substances. We may incur significant costs to comply with such laws and regulations now or in the future.

Competition

The biotechnology and pharmaceutical industries are characterized by rapid innovation, intense and dynamic competition and a strong emphasis on proprietary products. While we believe that our proprietary iPSC product platform, scientific knowledge and experience in the field of cellular immunotherapy provide us with competitive advantages, we face potential competition from many different sources, including major pharmaceutical, specialty pharmaceutical and biotechnology companies, academic institutions and governmental agencies and public and private research institutions, as well as standard-of-care treatments, new products undergoing development and combinations of existing and new therapies. Any product candidates that we successfully develop and commercialize will compete with existing therapies and new therapies, including antibody-based therapies such as bi-specific antibodies, and combinations thereof, that may become available in the future.

Cellular immunotherapies for the treatment of cancer and autoimmune diseases have recently been an area of significant research and development by academic institutions and biopharmaceutical companies. Six autologous CAR T-cell therapies have been approved by the FDA for the treatment of relapsed / refractory hematologic malignancies: Kymriah (Novartis AG) for B-cell acute lymphoblastic leukemia (ALL) and for diffuse large B-cell lymphoma (DLBCL); Yescarta (Kite Pharma) for aggressive large B-cell lymphoma (LBCL); Tecartus (Kite Pharma) for mantle cell lymphoma or B-cell ALL; Breyanzi (Bristol-Myers Squibb Company) for aggressive LBCL; Abecma (Bristol-Myers Squibb Company) for multiple myeloma; and Carvykti (Janssen Biotech) for multiple myeloma.

We are developing our iPSC-derived CAR NK cell and CAR T-cell product candidates for the treatment of cancer and autoimmune diseases. While we believe our proprietary iPSC product platform and our off-the-shelf, multiplexed-engineered, iPSC-derived cell product candidates are highly differentiated, a number of clinical-stage companies are currently focused on the development of cellular immunotherapies for the treatment of cancer and autoimmune diseases. These competitive companies include, among others, Allogene Therapeutics, Inc., Arcellx, Inc., AstraZeneca plc, Autolus Therapeutics plc, Bristol-Myers Squibb Company, Cabaletta Bio, Inc., CARGO Therapeutics, Inc., Caribou Biosciences, Inc., Cartesian Therapeutics, Inc., Cellectis SA, Century Therapeutics, Inc., CRISPR Therapeutics AG, Galapagos NV, ImmunityBio, Inc., Janssen Biotech (Johnson & Johnson), Legend

Biotech Corporation, Kite Pharma (Gilead Sciences, Inc.), Kyverna Therapeutics, Inc., Nkarta, Inc., Novartis AG, Poseida Therapeutics, Inc., Sana Biotechnology, Inc. and Takeda Pharmaceutical Company Limited. Preclinical-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies.

We compete against our competitors in recruiting and retaining qualified scientific and management personnel and establishing clinical study sites and subject enrollment for clinical studies, as well as in acquiring technologies complementary to, or necessary for, our programs. Many of our competitors, either alone or with their collaboration partners, have substantially greater financial, technical and human resources than we do and significantly greater experience in the discovery and development of product candidates, obtaining FDA and other regulatory approvals of treatments and commercializing those treatments. Accordingly, our competitors may be more successful than us in obtaining approval for treatments and achieving widespread market acceptance.

We anticipate that we will face intense and increasing competition as new products enter the market and advanced technologies become available. We expect any treatments that we develop and commercialize to compete on the basis of, among other things, efficacy, safety, convenience of administration and delivery, price, the level of generic competition and the availability of reimbursement from government and other third-party payers. Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient or are less expensive than any products that we may develop. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours, which could result in our competitors establishing a strong market position before we are able to enter the market.

Insurance

We maintain product liability insurance for our clinical trials. We intend to expand our insurance coverage to include the sale of commercial products if marketing approval is obtained for products in development. However, insurance coverage is becoming increasingly expensive, and we may not be able to maintain insurance coverage at a reasonable cost or in sufficient amounts to protect us against losses due to liability. In addition, we may not be able to obtain commercially reasonable product liability insurance for any products approved for marketing.

Human Capital

Our success as a company depends upon the innovation, drive, and dedication of our employees, and we seek to attract, incentivize, and reward creative and performance-driven employees. We believe our commitment to our human capital resources is an important component of our business that enables us to deliver superior performance in our industry.

We focus on identifying, recruiting, developing and retaining a team of highly talented and motivated employees. As of December 31, 2023, we employed 181 employees, all of whom are full-time employees, including 82 in research and development, 49 in clinical development, manufacturing and regulatory affairs and 50 in general and administrative. We have never had a work stoppage, and none of our employees is represented by a labor organization or under any collective bargaining arrangements. We believe that our relationship with our employees is good, and we provide all employees with the opportunity to share their opinions in open dialogues with our human resources department and senior management.

Equity, Diversity, and Inclusion

We believe that an equitable, diverse, and inclusive workforce is a necessary foundation for innovation and dedication of our employees. Accordingly, we strive to promote diversity, inclusion and equal opportunity across the organization. We are committed to actively seeking out highly qualified women and minority candidates, as well as candidates with diverse backgrounds, skills and experiences. As of December 31, 2023, women made up 55% of our workforce and represented 50% of leadership positions at the director-level and above.

In addition, as of December 31, 2023, ethnic or racial minorities made up 54% of all of our employees, with 32% Asian, 12% Hispanic, 4% Black, 2% Native Hawaiian or other Pacific Islander and 4% of two or more races. Ethnic or racial minorities made up 43% of our director-level and above employees, with 35% Asian, 3% Hispanic, 3% Black, and 2% of two or more races. The age breakdown of our employee workforce consisted of 49% of employees between the ages of 25 – 39 years old, 45% of employees between the ages of 40 – 50 years old, and 6% of employees 55 and older.

Health and Safety

The success of our business is fundamentally connected to the well-being, health and safety of our employees, and we are committed to providing a safe, healthy and secure workplace for our employees. We have an environmental, health and safety program and several cross-functional committees to support our environmental, health and safety program. We routinely train and

educate our employees on workplace safety and security and maintain various compliance programs to support this commitment. We continue to monitor and adjust our safety training and protocols as needed to ensure the safety and wellbeing of our workforce.

Compensation and Benefits

We offer competitive pay, with performance-based bonuses and equity awards. The principal purposes of our equity and cash incentive plans are to attract, retain and reward personnel through the granting of stock-based and cash-based compensation awards in order to increase stockholder value and the success of our company by motivating such individuals to perform to the best of their abilities and achieve our objectives. We have a comprehensive benefits program offering flexibility for our employees’ individual needs and requirements. Our benefits program includes a choice of medical plans, vision and dental coverage, flexible spending accounts for health and dependent day care needs, and income protection through life, AD&D, short term and long term disability coverage, sick leave, paid family leave, and generous paid time off. We offer a 401(k) retirement plan with company matching a percentage of employee contributions, an employee assistance program, and onsite fitness centers at no cost to our employees.

Employee Development and Engagement

We are focused on attracting and retaining a team of highly talented and motivated employees. We invest in and develop all levels of employees by engaging in ongoing career pathing and professional development conversations throughout an employee’s tenure. In addition, we provide targeted leadership development programs for frontline leaders through executive leadership programs and offer a number of professional, management and leadership development training programs to help our employees develop cross-functional skills and tools to grow their careers.

Employees are incentivized for key contributions through awards programs that recognize their commitment and dedication by demonstrating our Fate Pathways to Success.

We focus on identifying, recruiting, developing and retaining a team of highly talented and motivated employees. We believe that our relationship with our employees is good. We believe our commitment to our human capital resources is an important component of our business that enables us to deliver superior performance in our industry. We provide all employees with the opportunity to share their opinions in open dialogues with our human resources department and senior management. We provide all employees a wide range of professional development experiences, both formal and informal. The safety and wellbeing of our employees is a paramount value for us. Further, the health and wellness of our employees are critical to our success. We provide our employees with access to a variety of flexible and convenient health and wellness programs. Such programs are designed to support employees’ physical and mental health by providing tools and resources to help them improve or maintain their health status and encourage engagement in healthy behaviors. Additionally, we provide competitive compensation and benefits. In addition to salaries, these programs can include annual bonuses, stock-based compensation awards, a 401(k) plan with employee matching opportunities, healthcare and insurance benefits, health savings and flexible spending accounts, paid time off, family leave, and family care resources.

Environmental Sustainability

We recognize the importance of the environment to a healthy, sustainable future for our business, our patients, and communities. Our headquarters located in San Diego, California was designed to be energy efficient through the use of LED lighting, energy efficient air handling units, a fully integrated building management system, and other tools. Our facilities are also outfitted with smart building solutions, such as occupancy sensors and air conditioning units reducing airflow based on occupancy. Water-saving bathroom faucets and toilets are installed throughout the building to help reduce water consumption. The exterior of our building is made up of draught tolerant landscaping to reduce the volume of water needed to maintain plant life around the building. Employees are also provided free access to electric vehicle charging stations. Our commitment to environmental sustainability is ongoing and we continue to be mindful of how we can minimize our environmental footprint as a company.

Item 1A. Risk Factors

You should carefully consider the following risk factors, as well as the other information in this Annual Report on Form 10-K, and in our other public filings. The occurrence of any of these risks could harm our business, financial condition, results of operations and/or growth prospects or cause our actual results to differ materially from those contained in forward-looking statements we have made in this report and those we may make from time to time. You should consider all of the risk factors described in our public filings when evaluating our business.

Risks Related to Our Financial Condition

Our ongoing and planned operations, including the development of our product candidates, will require substantial additional funding, without which we will be unable to complete preclinical or clinical development of, or obtain regulatory approval for, or commercialization of our product candidates.

We are currently advancing multiple product candidates through clinical development, and conducting preclinical research and development activities in other programs. Drug development is expensive, and we expect our research and development expenses to remain significant in connection with our ongoing activities, particularly as we advance our current product candidates in clinical trials and seek to initiate clinical development for additional product candidates.

As of December 31, 2023, our cash and cash equivalents and investments were $316.2 million. We intend to use our cash and cash equivalents and investments primarily to fund the advancement and clinical development of our current product candidates and our ongoing preclinical, discovery and research programs, and for working capital and general corporate purposes. However, our operating plan may change as a result of many factors currently unknown to us, and we may need to seek additional funds sooner than planned, through public or private equity or debt financings, government or other third-party funding, marketing and distribution arrangements and other collaborations, strategic and licensing arrangements or a combination of these approaches. In any event, we will require additional capital to obtain regulatory approval for, and to commercialize our existing product candidates and any other product candidates we may identify and develop. Even if we believe we have sufficient funds for our current or future operating plans, we may seek additional capital if market conditions are favorable or if we have specific strategic considerations. Our future capital requirements will depend on many factors, including, but not limited to:

Any additional fundraising efforts may divert our management from their day-to-day activities, which may adversely affect our ability to develop and commercialize our product candidates. In addition, we cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to us, if at all. Moreover, the terms of any financing may adversely affect the holdings or the rights of our stockholders and the issuance of additional securities, whether equity or debt, by us, or the possibility of such issuance, may cause the market price of our shares to decline. The sale of additional equity or convertible securities would dilute all of our stockholders. The incurrence of indebtedness would result in increased fixed payment and interest obligations and we may be required to agree to certain restrictive covenants, such as limitations on our ability to incur additional debt, limitations on our ability to acquire, sell or license intellectual property rights and other operating restrictions that could adversely impact our ability to conduct our business. We could also be required to seek funds through arrangements with collaborative partners or otherwise at a different stage than otherwise would be desirable and we may be required to relinquish rights to some of our technologies or product candidates or otherwise agree to terms unfavorable to us, any of which may have a material adverse effect on our business, operating results and prospects. In addition, while the overall impacts of the ongoing wars between Russia and Ukraine and between Israel and Hamas on the global economy remain unknown and difficult to predict, these events caused significant disruptions and created uncertainties in the global financial markets, and the economic impacts of these and other similar global events could materially and adversely affect our ability to raise capital through equity or debt financings in the future.

If we cannot raise additional capital or obtain adequate funds, we may be required to curtail significantly our research and clinical programs or may not be able to continue our research or clinical development of our product candidates. Our failure to raise additional capital, or obtain adequate funds, will have a material adverse effect on our business, prospects, financial condition, results of operations, and market price of shares of our common stock.

We have a limited operating history, have incurred significant losses since our inception, and anticipate that we will continue to incur significant losses for the foreseeable future.

We are a clinical-stage biopharmaceutical company formed in 2007 with a limited operating history. We have not yet obtained regulatory approval for any of our product candidates or generated any revenues from therapeutic product sales. Since inception, we have incurred significant net losses in each year and, as of December 31, 2023, we had an accumulated deficit of $1.2 billion. We expect to continue to incur losses for the foreseeable future as we continue to fund our ongoing and planned clinical trials of our product candidates, and our other ongoing and planned research and development activities. We also expect to incur significant operating and capital expenditures as we continue our research and development of, and seek regulatory approval for, our product candidates, in-license or acquire new product candidates for development, implement additional infrastructure and internal systems, and hire additional scientific, clinical, and administrative personnel. We anticipate that our net losses for the next several years could be significant as we conduct our planned operations.

Because of the numerous risks and uncertainties associated with pharmaceutical, biological, and cell therapy product development, we are unable to accurately predict the timing or amount of increased expenses or when, or if, we will be able to achieve profitability. In addition, our expenses could increase if we are required by the FDA, or comparable foreign regulatory authorities, to perform studies or trials in addition to those currently expected, or if there are any delays in completing our clinical trials, preclinical studies, process development, manufacturing activities, or the research and development of any of our product candidates. The amount of our future net losses will depend, in part, on the rate of increase in our expenses, our ability to generate revenues and our ability to raise additional capital. These net losses have had, and will continue to have, an adverse effect on our stockholders’ equity and working capital.

We have broad discretion over the use of our cash, cash equivalents, and investments and may not use them effectively.

Our management has broad discretion to use our cash, cash equivalents, investments and any additional funds that we may raise to fund our operations and could spend these funds in ways that do not improve our results of operations or enhance the value of our common stock. The failure by our management to apply these funds effectively could result in financial losses that could have a material adverse effect on our business, cause the price of our common stock to decline or delay the development of our product candidates. We may invest our cash and cash equivalents in a manner that does not produce income or that loses value.

Risks Related to the Discovery, Development and Regulation of Our Product Candidates

If we fail to complete the preclinical or clinical development of, or to obtain regulatory approval for, our product candidates, our business would be significantly harmed.

All of our product candidates are currently in research or early clinical development. We have not completed clinical development of or obtained regulatory approval for any of our product candidates. Only a small percentage of research and development programs ultimately result in commercially successful products, and we cannot assure you that any of our product candidates will demonstrate the safety, purity and potency, or efficacy profiles necessary to support further preclinical study, clinical development or regulatory approval.

We may experience delays in, or cancel our ongoing and planned clinical development activities or research and development activities for any of our product candidates for a variety of reasons, including:

For example, in January 2023, we announced the discontinuation of our FT516, FT596, FT538, and FT536 NK cell programs to focus our resources on advancing our most innovative and differentiated programs. We also announced the termination of our Collaboration and Option Agreement with Janssen, which took effect on April 3, 2023. As a result of the termination, we performed wind-down activities for the collaboration in the first quarter of 2023, including winding down the development of two product candidates that had been expected to enter the clinic in 2023.

Additionally, we will only be able to obtain regulatory approval to market a product candidate if we can demonstrate, to the satisfaction of the FDA or comparable foreign regulatory authorities, in well-designed and conducted clinical trials that such product candidate is manufactured in accordance with applicable regulatory requirements, is safe, pure and potent, or effective, and otherwise meets the appropriate standards required for approval for a particular indication. Our ability to obtain regulatory approval of our product candidates depends on, among other things, completion of additional preclinical studies, process development and manufacturing activities, and clinical trials, whether our clinical trials demonstrate statistically significant efficacy with safety profiles that do not potentially outweigh the therapeutic benefit, and whether regulatory agencies agree that the data from our clinical trials and our manufacturing operations are sufficient to support approval. In addition, the approval by the FDA of new products in the same indications that we are studying may change the standard of care, and this may result in the FDA or other regulatory agencies requesting that we conduct additional studies to show that our product candidate is superior to the new standard of care. Securing regulatory approval also requires the submission of information about product manufacturing operations to, and inspection of manufacturing facilities by, the relevant regulatory authority. The results of our current and future clinical trials may not meet the FDA’s or other regulatory agencies’ requirements to approve a product candidate for marketing, and the regulatory agencies may otherwise determine that our manufacturing operations are insufficient to support approval. We may need to conduct preclinical studies and clinical trials that we currently do not anticipate, including as a result of changes in the standard of care. If we fail to complete preclinical or clinical development of, or obtain regulatory approval for, our product candidates, we will not be able to generate any revenues from product sales and our ability to receive milestone or other payments under any collaboration agreements may be impaired, which will harm our business, prospects, financial condition and results of operations.

We may face delays in initiating, conducting or completing our clinical trials, and we may not be able to initiate, conduct or complete them at all.

We are heavily dependent on our ability to complete the clinical development of, and obtain regulatory approval for, our product candidates. We have not completed the clinical trials necessary to support an application for approval to market any of our product candidates. We, or any investigators who initiate or conduct clinical trials of our product candidates, may experience delays in our current or future clinical trials, and we do not know whether we or our investigators will be able to initiate, enroll patients in, or complete, clinical trials of our product candidates on time, if at all. Current and future clinical trials of our product candidates may be delayed, unsuccessful or terminated, or not initiated at all, as a result of many factors, including factors related to:

If there are delays in initiating or conducting any clinical trials of our product candidates or any of these clinical trials are terminated before completion, the commercial prospects of our product candidates will be harmed. In addition, any delays in initiating, conducting or completing our clinical trials or adjustments to certain of our study protocols and procedures, including as a result of any shortage of materials or agents necessary to conduct our studies or as a result of any future public health crisis or other public health concerns or other factors, will increase our costs, slow down our product candidate development and regulatory approval process, and jeopardize our ability to gain regulatory approval, commence product sales and generate revenues. Furthermore, many of the factors that cause, or lead to, a delay in the initiation, conduct or completion of clinical trials may also ultimately lead to the denial of regulatory approval of our product candidates. Any of these occurrences would significantly harm our business, prospects, financial condition, results of operations, and market price of shares of our common stock.

The manufacture and distribution of our cell product candidates, particularly our iPSC-derived cell product candidates, is complex and subject to a multitude of risks. These risks could substantially increase our costs and limit the clinical and commercial supply of our product candidates, and the development and commercialization of our product candidates could be substantially delayed or restricted if the FDA or other regulatory authorities impose additional requirements on our manufacturing operations or if we are required to change our manufacturing operations to comply with regulatory requirements.

The manufacture and supply of our cell product candidates involves novel processes that are more complex than those required for most small molecule drugs and other cellular immunotherapies, and accordingly present significant challenges and are subject to multiple risks. For our iPSC-derived product candidates, these complex processes include reprogramming human fibroblasts to obtain iPSCs, in some cases genetically engineering these iPSCs, and differentiating the iPSCs to obtain the desired cell product candidate. As a result of the complexities in manufacturing biologics and distributing cell therapies, the cost to manufacture and distribute biologics and cell therapies in general, and our cell product candidates in particular, is generally higher than for traditional small molecule chemical compounds. In addition, our cost of goods development is at an early stage. The actual cost to manufacture and process our product candidates could be greater than we expect and could materially and adversely affect the commercial viability of our product candidates.

We have limited experience in the manufacture of cell-based therapies. We are still developing optimized and reproducible manufacturing processes for clinical and commercial-scale manufacturing of our product candidates, and none of our manufacturing processes have been validated for commercial production of our product candidates. We may face multiple challenges as we scale our manufacturing for large-scale clinical trials or commercial-scale including, among others, cost overruns, potential problems with process scale-up, process reproducibility, stability issues, compliance with good manufacturing practices, lot consistency and timely availability of raw materials. In addition, we are continuing to optimize our protocols for the supply and transport of our product candidates for distribution to clinical trial sites. Although we are working to develop reproducible and commercially viable manufacturing processes for our product candidates, and effective protocols for the supply and transport of our product candidates, doing so is a difficult and uncertain task.

We may make changes or be required by the FDA to make changes to our manufacturing processes, including materials and equipment used in manufacturing our product candidates, as we continue to develop and refine the manufacturing and distribution processes for our product candidates for advanced clinical trials and commercialization, and we cannot be sure that even minor changes in these processes, materials, and equipment will not cause our product candidates to perform differently and affect the results of our ongoing and planned clinical trials or the performance of the product once commercialized. In some circumstances, changes in our manufacturing operations, including to our protocols, processes, materials or facilities used, may require us to perform additional preclinical or comparability studies, or to collect additional clinical data from patients prior to undertaking additional clinical studies or filing for regulatory approval for a product candidate. These requirements may lead to delays in our clinical development and commercialization plans for our product candidates, and may increase our development costs substantially.

The manufacturing processes for any products that we may develop are subject to FDA and foreign regulatory authority approval requirements, and we and any contract manufacturing organizations (CMOs) or other third party manufacturers that we may engage for manufacturing our product candidates, will need to meet, all applicable FDA and foreign regulatory authority requirements on an ongoing basis. Our existing product candidates are currently manufactured by us and our current manufacturing operations, including protocols, processes, materials, and facilities, may not support regulatory approval of our existing product candidates. We may be required to identify alternative protocols, processes, materials or facilities for the manufacture of any of these product candidates in compliance with applicable regulatory requirements. In addition, we may be required to make changes to our protocols for the supply and transport of our product candidates to enable effective distribution of our product candidates. Any modifications to our manufacturing and supply protocols, processes, materials or facilities, and any delays in, or inability to, establish acceptable manufacturing and supply operations for our product candidates could require us to incur additional development costs or result in delays to our clinical development. If we or any CMOs or other third-party manufacturers that we may engage for manufacturing our product candidates are unable to reliably produce products to specifications acceptable to the FDA or other regulatory authorities, we may not obtain or maintain the regulatory approvals we need to commercialize such products. Even if we obtain regulatory approval for any of our product candidates, there is no assurance that either we or any CMOs or other third-party manufacturers will be able to manufacture the approved product to specifications acceptable to the FDA or other regulatory authorities, to produce it in sufficient quantities and on the requisite timelines to meet the requirements for the potential launch of the product, or to meet potential future demand. Additionally, changes in regulatory requirements may require us or any third-party manufacturers to perform additional studies or to modify protocols, processes, materials or facilities for the manufacture of our product candidates or any components thereof. Any of these challenges could delay initiation or completion of clinical trials, require bridging clinical trials or the repetition of one or more clinical trials, increase clinical trial costs, delay approval of our product candidates, impair commercialization efforts, increase our cost of goods, and have an adverse effect on our business, financial condition, results of operations and prospects.

A disruption to our manufacturing operations, or the inability by us or our third-party suppliers or manufacturers to manufacture sufficient quantities of our product candidates at acceptable quality levels or costs, or at all, would materially and adversely affect our business.

Developing manufacturing processes to support clinical studies and commercialization requirements is a difficult and uncertain task, and there are risks associated with scaling to the level required for clinical trials or commercialization, including, among others, cost overruns, potential problems with process scale-out, process reproducibility, stability and purity issues, lot consistency, and timely availability of acceptable reagents and raw materials. If we are unable to scale to the level required for the conduct of clinical trials or commercialization, we may not be able to produce our product candidates in a sufficient quantity to conduct our ongoing and planned clinical trials, or to meet demand if any product candidates are approved for commercialization. We have not yet caused any of our product candidates to be manufactured or processed on a commercial scale and may not be able to do so for any of our product candidates.

We are substantially dependent on our own internal manufacturing facilities in San Diego, California for the production of our product candidates, and we rely, and may continue to rely, on third parties for the manufacture of certain components to manufacture our product candidates for use in conducting clinical trials. The facilities used to manufacture our product candidates, including our own facilities, must be evaluated by the FDA or other foreign regulatory agencies pursuant to inspections that will be conducted after we submit an application to the FDA or other foreign regulatory agencies. If the FDA or a comparable foreign regulatory authority finds deficiencies with or does not approve these facilities for the manufacture of our product candidates or if it later finds deficiencies or withdraws any such approval in the future, we may not be able to locate additional or replacement facilities to produce such product candidates or materials in a timely manner and on commercially reasonable terms, or at all. This would significantly impact our ability to develop, obtain regulatory approval for or market our product candidates, if approved.

Because we rely on our own manufacturing facilities to produce our product candidates and on third parties for the manufacture of certain components, we are required to transfer certain manufacturing process know-how and certain intermediates to third parties, including larger-scale facilities operated by a CMO or by us, to facilitate manufacture of our product candidates for clinical trials and commercialization. Transferring manufacturing testing and processes and know-how is complex and involves review and incorporation of both documented and undocumented processes that may have evolved over time. In addition, transferring production to different facilities may require utilization of new or different processes to meet the specific requirements of a given facility. We and any CMOs or third parties that we engage to manufacture our product candidates will need to conduct significant development work to transfer these processes and manufacture each of our product candidates for clinical trials and commercialization. In addition, we may be required to demonstrate the comparability of material generated by any CMO or third parties that we engage for manufacturing our product candidates with material previously produced and used in testing. Any inability to manufacture comparable drug product by us or any CMOs or third parties that we engage to manufacture our product candidates could delay the continued development of our product candidates.

In addition to relying on third parties for the manufacture of certain components for the manufacture of our product candidates, we manufacture our product candidates ourselves, and intend to manufacture some or all of the clinical supply of our iPSC-derived NK-cell and T-cell product candidates for our ongoing and planned clinical trials. To do so, we will need to scale up our own manufacturing operations, as we do not currently have the infrastructure or capability internally to manufacture sufficient quantities of each of our product candidates to support the conduct of each of our clinical trials or commercialization of each of our product candidates, if approved. Accordingly, we will be required to make significant investments to maintain and expand our existing Good Manufacturing Practice (GMP) manufacturing capabilities and facilities, establish additional GMP manufacturing facilities, conduct GMP production, and process and scale up development and technology transfer activities for the manufacture of our product candidates, and our efforts to scale our own manufacturing operations may not succeed.

Even if we are successful in developing manufacturing capabilities sufficient for clinical and commercial supply, problems with our manufacturing operations or those of the third-party manufacturers upon which we rely, including difficulties with production costs and yields, quality control, stability of the product, quality assurance testing, operator error, shortages of qualified personnel, shortages of materials and supplies, facility shutdowns, global pandemics or other public health concerns, war or armed conflicts such as the ongoing wars between Russia and Ukraine and between Israel and Hamas, natural disasters (including due to the effects of climate change) or other reasons, as well as compliance with strictly enforced federal, state and foreign regulations, could result in product defects or manufacturing failures that result in lot failures, product recalls, product liability claims or insufficient supplies of our product candidates for our ongoing and planned clinical trials or eventual commercialization. Further, delays in regulatory inspections, commissioning and receiving regulatory approvals for our manufacturing capabilities or facilities, including any new facilities could delay our development plans, including the initiation and conduct of our ongoing and planned clinical trials. In addition, we and our third-party manufacturers may have limited manufacturing capacity for certain product candidates or components used in manufacturing our product candidates, and we may fail to locate suitable additional or replacement manufacturing capacity, including for the manufacture of our product candidates in compliance with current GMP (cGMP) or current Good Tissue Practice (cGTP), on a reasonable basis or at all. Any such failure could be the basis for the FDA to issue a warning letter, withdraw approvals for product candidates previously granted to us, or take other regulatory or legal action, including recall or seizure of outside supplies of the product candidate, total or partial suspension of production, suspension of ongoing clinical trials, refusal to approve pending

applications or supplemental applications, detention of product, refusal to permit the import or export of products, injunction or imposing civil and criminal penalties.

Furthermore, certain of the components currently used in manufacturing our product candidates are research-grade only, and we may encounter problems obtaining or achieving adequate quantities and quality of clinical grade materials that meet FDA, European Medicines Agency, or other applicable standards or specifications with consistent and acceptable production yields and costs. In addition, if contaminants are discovered in our supply of product candidates or in our manufacturing facilities or those of our third-party suppliers and manufacturers, such manufacturing facilities may be closed for an extended period of time to investigate and remedy the contamination. Any such events could delay or prevent our ability to obtain regulatory approval for or commercialize our product candidates, which would adversely affect our business, prospects, financial condition and results of operations.

Because our approach to the development of product candidates is based on novel and unproven technologies, it is subject to a substantial degree of technological uncertainty and we may not succeed in developing any of our product candidates.

All of our current product candidates are based on our novel iPSC platform, and some of our product candidates utilize novel genome editing technologies. To date, no iPSC-derived therapeutic product candidates have been approved in the United States or worldwide, and there have been only a limited number of regulatory approvals of genome edited therapeutics, and similarly a limited number of clinical trials involving the use of a therapeutic product candidate manufactured using a master iPSC line or genome edited cells. The development of such complex cell therapies is a relatively new and emerging field, and the scientific research that forms the basis of our efforts to discover and develop iPSC-derived and genome edited cellular immunotherapies is ongoing. We may determine to incorporate information learned from this research into the design of our ongoing Phase 1 clinical trials of our iPSC product candidates, as well as our planned future clinical trials, which could delay or impair our clinical development activities. We may ultimately discover that our product candidates do not possess certain properties required for therapeutic effectiveness or protection from toxicity in our target patient populations, or they may exhibit undesirable side effects as more patient data become available. In addition, our product candidates may demonstrate different chemical and pharmacological properties in patients than they do in laboratory studies. It may take many years before we develop a full understanding of the pharmacological properties of our product candidates, and we may never know precisely how they function in vivo. As with any new biologic or product developed using novel technologies, our product candidates have an unknown immunogenicity profile. As a result, our cellular immunotherapy product candidates may trigger immune responses that inhibit their therapeutic effects or cause adverse side effects. In addition, one or more of our product candidates may:

Any such problems that affect one of our product candidates may have an unfavorable impact on all of our product candidates. As a result, we may never succeed in developing a marketable product and we may never become profitable, which would have an adverse effect on our business, prospects, financial condition, results of operations, and market price of shares of our common stock.

We anticipate that our current product candidates and any future product candidates may be used in combination with third-party drugs or biologics, some of which may still be in development, and we have limited or no control over the supply, regulatory status, or regulatory approval of such drugs or biologics.

Certain of our product candidates are being developed for use in combination with one or more other cancer therapies, such as monoclonal antibodies, and other current or future product candidates may be used in combination with other biologics or drugs, both approved and unapproved, such as fludarabine. Our ability to develop and ultimately commercialize our current product candidates and any future product candidates used in combination with another drug or biologic will depend on our ability, or the ability of third-party clinical trial sites on which we rely, to access such drugs or biologics on commercially reasonable terms for the clinical trials and their availability for use with the commercialized product, if approved. We cannot be certain that we, or third-party clinical trial sites on which we rely, will be able to secure a steady supply of such drugs or biologics on commercially reasonable terms or at all.

Any failure by us, or by third-party clinical trial sites on which we rely, to secure a steady supply of such drugs or biologics may delay our development timelines, increase our costs and jeopardize our ability to develop our current product candidates and any future product candidates as commercially viable therapies. If any of these occur, our business, financial condition, results of operations, stock price and prospects may be materially harmed.

Moreover, the development of product candidates for use in combination with another product or product candidate may present challenges that are not faced for single agent product candidates. For example, the FDA or comparable foreign regulatory authorities may require us to use more complex clinical trial designs in order to evaluate the contribution of each product and product candidate to any observed effects. It is possible that the results of such trials could show that any positive previous trial results are attributable to the combination therapy and not our current product candidates and any future product candidates. Moreover, following product approval, the FDA or comparable foreign regulatory authorities may require that products used in conjunction with each other be cross labeled for combined use. To the extent that we do not have rights to the other product, this may require us to work with a third party to satisfy such a requirement. Moreover, developments related to the other product may impact our clinical trials for the combination as well as our commercial prospects should we receive marketing approval. Such developments may include changes to the other product’s safety or efficacy profile, changes to the availability of the approved product, quality, manufacturing and supply issues, and changes to the standard of care.

In the event that any collaborator or supplier cannot continue to supply their products on commercially reasonable terms, we would need to identify alternatives for accessing such products. Additionally, should the supply of products from any collaborator or supplier be interrupted, delayed or otherwise be unavailable, our clinical trials may be delayed. In the event we are unable to source an alternative supply or are unable to do so on commercially reasonable terms, our business, financial condition, results of operations, stock price and prospects may be materially harmed.

In addition, to the extent a third-party clinical trial site on which we rely sources a combination therapy itself and does not submit the costs of such therapy to government programs or patients’ insurance, the costs of such therapy may be passed on to us, which could harm our business, financial condition, results of operations, stock price and prospects.

If we encounter difficulties enrolling patients in our clinical trials, including as a result of competition for patients, our clinical development activities could be delayed or otherwise adversely affected.

We are required to identify and enroll a sufficient number of patients with the disease under investigation for each of our ongoing and planned clinical trials of our product candidates, and we may not be able to identify and enroll a sufficient number of patients, or those with required or desired characteristics and who meet certain criteria, in a timely manner. In addition, we will be competing with other clinical trials of product candidates being developed by our competitors in the same therapeutic areas, and potential patients who might be eligible for enrollment in one of our clinical trials may instead choose to enroll in a trial being conducted by one of our competitors.

Our ability, and the ability of investigators, to enroll patients in our ongoing and planned clinical trials of our product candidates is affected by factors including:

Moreover, development of certain of our product candidates as treatment for autoimmune diseases represents a novel approach where B cells may play a role in initiating or maintaining disease treatment, and potential patients and their doctors may choose to use conventional therapies, such as corticosteroids or systemic immunosuppressive medications, rather than enroll patients in our clinical trials.

In addition, certain of our clinical trial sites at times have delayed or paused patient enrollment in clinical trials as a result of the COVID-19 pandemic and supply chain shortages, and may do so again in the future for a variety of reasons. The extent and duration of such delays and disruptions, and the overall impact on the timing and conduct of our clinical trials, are uncertain. If we have difficulty enrolling a sufficient number of patients to conduct our clinical trials as planned, we may need to delay or terminate ongoing or planned clinical trials, either of which would have an adverse effect on our business, prospects, financial condition, results of operations, and market price of shares of our common stock.

The clinical development of our product candidates could be substantially delayed if we are required to conduct unanticipated studies, including preclinical studies or clinical trials, or if the FDA imposes other requirements or restrictions including on the manufacture, of our product candidates.

The FDA may require us to generate additional preclinical, product, manufacturing, or clinical data as a condition to continuing our current clinical trials, or initiating and conducting any future clinical trials of our current product candidates or other cell product candidates that we may identify. Additionally, the FDA may in the future have comments, or impose requirements, on the conduct of our clinical trials or the initiation of clinical trials or any of our other iPSC-derived cell product candidates, including the protocols, processes, materials and facilities we use to manufacture our product candidates and potential future product candidates in support of clinical trials. Any requirements to generate additional data, or redesign or modify our protocols, processes, materials or facilities, or other additional comments, requirements or impositions by the FDA, may cause delays in the initiation or conduct of the current or future clinical trials for our product candidates and subsequent development activities for our product candidates, and could require us to incur additional development or manufacturing costs and resources, seek funding for these increased costs or resources or delay our timeline for, or cease, our preclinical or clinical development activities for our product candidates, or could create uncertainty and additional complexity in our ability to obtain regulatory approval for our product candidates.

Further, if the results of our clinical trials are inconclusive, or if there are safety concerns or adverse events associated with our existing product candidates or any other product candidates we may identify, we may:

Even if our current and planned clinical trials are successful, we will need to conduct additional clinical trials, which may include registrational trials, trials in additional patient populations or under different treatment conditions, and trials using different manufacturing protocols, processes, materials or facilities or under different manufacturing conditions, before we are able to seek approvals for our product candidates from the FDA and regulatory authorities outside the United States to market and sell these product candidates. If we fail to meet the requirements to support continued clinical development, our clinical development activities for any of our product candidates are delayed or suspended, or we fail to obtain or maintain regulatory approvals with an acceptable scope, our business, prospects, financial condition and results of operations will be harmed.

We are pursuing multiple programs and product candidates in our novel cell therapy development pipeline using an approach that is designed to enable rapid incorporation of new product features. If we elect to incorporate these new features into next-generation product candidates, this may render our existing product candidates obsolete, and we may devote our limited resources in pursuit of a particular program for which there is a greater potential for success and fail to capitalize on development opportunities or product candidates including those which may be more advanced in development.

We focus on the development of programmed cellular immunotherapies for patients with cancer and autoimmune diseases, including off-the-shelf NK- and T-cell product candidates derived from clonal master engineered iPSC lines. Because our iPSC product platform is designed to enable rapid incorporation of novel functional product features in an evolving clinical setting, we may elect to incorporate these discoveries into next-generation product candidates that render our existing product candidates, including product candidates under clinical development, obsolete. Additionally, because we have limited financial and personnel resources, we may elect or be required to abandon or delay the pursuit of opportunities with existing or future product candidates, including those that may be more advanced in development than those we ultimately elect to pursue. For example, in January 2023, we announced the discontinuation of our FT516, FT596, FT538, and FT536 NK cell programs to focus our resources on advancing our most innovative and differentiated programs. We are also expanding our research and development efforts into areas outside of oncology, such as autoimmune diseases, where we have limited or no experience. Due to these factors, our spending on current and future research and development programs and product candidates and the scientific innovation arising from these expenditures, may not yield commercially viable product candidates.

Our product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit their commercial potential or result in significant negative consequences following any potential marketing approval.

During the conduct of clinical trials, patients may report changes in their health, including illnesses, injuries and discomforts, to their doctor. Often, it is not possible to determine whether or not the product candidate being studied caused these conditions. Regulatory authorities may draw different conclusions and may require us to pause our clinical trials or require additional testing to confirm these determinations, if they occur.

In addition, it is possible that as we test our product candidates in larger, longer and more extensive clinical trials, or as use of these product candidates becomes more widespread if they receive regulatory approval, illnesses, injuries, discomforts and other adverse events that were not observed in earlier trials, as well as conditions that did not occur or went undetected in previous trials, may be reported by subjects or patients. Many times, drug-related side effects are only detectable after investigational products are tested in large-scale pivotal trials or, in some cases, after they are made available to patients on a commercial scale after approval. If additional clinical experience indicates that any of our product candidates have side effects or cause serious or life-threatening side effects, the development of the product candidate may fail or be delayed, or, if the product candidate receives regulatory approval, such approval may be revoked, which would harm our business, financial condition, results of operations and prospects.

Drug-related side effects could also affect subject recruitment or the ability of enrolled subjects to complete the trial or result in potential product liability claims. Any of these occurrences may harm our business prospects significantly.

We study our product candidates in patient populations with significant comorbidities that may result in deaths or serious adverse events or unacceptable side effects and require us to abandon or limit our clinical development activities.

Patients treated with our current product candidates may also receive chemotherapy, radiation, and/or other high dose or myeloablative treatments in the course of treatment of their disease, and may therefore experience side effects or adverse events, including death, that are unrelated to our product candidates. While these side effects or adverse events may be unrelated to our product candidates, they may still affect the success of our clinical studies. The inclusion of critically ill patients in our clinical studies may result in deaths or other adverse medical events due to underlying disease or to other therapies or medications that such patients may receive. Any of these events could prevent us from advancing our product candidates through clinical development, and from obtaining regulatory approval, and would impair our ability to commercialize our product candidates. Any inability to advance our existing product candidates or any other product candidate through clinical development would have a material adverse effect on our business, and the value of our common stock would decline.

Because our product candidates are based on novel technologies, it is difficult to predict the regulatory approval process and the time, the cost and our ability to successfully initiate, conduct and complete clinical development, and obtain the necessary regulatory and reimbursement approvals, required for commercialization of our product candidates, if approved.

Our cell programming technology and platform for generating cell therapy products using iPSCs represent novel therapeutic approaches, and to our knowledge there are currently no iPSC-derived cell products approved anywhere in the world for commercial sale. As such, it is difficult to accurately predict the type and scope of challenges we may incur during development of our product

candidates, and we face uncertainties associated with the preclinical and clinical development, manufacture and regulatory requirements for the initiation and conduct of clinical trials, regulatory approval, and reimbursement required for successful commercialization of these product candidates. In addition, because our iPSC-derived cell product candidates are all in the early clinical or preclinical stage, we are currently assessing safety in humans and have not yet been able to assess the long-term effects of treatment. Animal models and assays may not accurately predict the safety and efficacy of our product candidates in our target patient populations, and appropriate models and assays may not exist for demonstrating the safety and purity of our product candidates, as required by the FDA and other regulatory authorities for ongoing clinical development and regulatory approval.

The preclinical and clinical development, manufacture, and regulatory requirements for approval of novel product candidates such as ours can be more expensive and take longer than for other more well-known or extensively studied pharmaceutical or biopharmaceutical product candidates due to a lack of prior experiences on the side of both developers and regulatory agencies. Additionally, due to the uncertainties associated with the preclinical and clinical development, manufacture, and regulatory requirements for approval of our product candidates, we may be required to modify or change our preclinical and clinical development plans or our manufacturing activities and plans, or be required to meet stricter regulatory requirements for approval. Any such modifications or changes could delay or prevent our ability to develop, manufacture, obtain regulatory approval or commercialize our product candidates, which would adversely affect our business, financial condition and results of operations.

Cellular immunotherapies, and iPSC-derived cell therapies in particular, represent relatively new therapeutic areas, and the FDA has cautioned consumers about potential safety risks associated with cell therapies. For example, in November 2023, the FDA announced that it would be conducting an investigation into reports of T-cell malignancies following BCMA-directed or CD19-directed autologous CAR T-cell immunotherapies following reports of T-cell lymphoma in patients receiving these therapies. In January 2024, the FDA determined that new safety information related to T-cell malignancies should be included in the labeling with boxed warning language on these malignancies for all BCMA- and CD19-directed genetically modified autologous T-cell immunotherapies. To date, there are relatively few approved cell therapies, and the development of any cell therapy may be placed on hold by the FDA upon the detection of any unexpected safety event to evaluate the potential relevance of such novel technology to the occurrence of such safety event, highlighting the technical and regulatory risk of working with new technology. As a result, the regulatory approval process for product candidates such as ours is uncertain and may be more expensive and take longer than the approval process for cell therapy product candidates based on other, better known or more extensively studied technologies and therapeutic approaches.

Regulatory requirements in the United States and in other countries governing the development of cell therapy products and therapeutic products created with gene editing technology have changed frequently and the FDA or other regulatory bodies may change the requirements, or identify different regulatory pathways, for approval for any of our product candidates. The FDA previously established the Office of Tissues and Advanced Therapies (OTAT) within the Center for Biologics Evaluation and Research (CBER) to consolidate the review of cell therapy and related products, and to advise CBER on its review. In September 2022, the FDA announced retitling of OTAT to the Office of Therapeutic Products (OTP) and elevation of OTP to a “Super Office” to meet its growing cell and gene therapy workload and new commitments under the Prescription Drug User Fee Act agreement for fiscal years 2023-2027. It is possible that over time new or different divisions may be established or be granted the responsibility for regulating cell and/or gene therapy products, including iPSC-derived cell products made with gene editing technology, such as ours. The regulatory review divisions and committees, and any new guidelines they promulgate, may lengthen the regulatory review process, require us to perform additional studies or clinical trials, and delay or prevent development, approval, and commercialization of our product candidates. As a result, we may be required to change our regulatory strategy or to modify our applications for regulatory approval, which could delay and impair our ability to complete the preclinical and clinical development and manufacture of, and obtain regulatory approval for, our product candidates. Changes in regulatory authorities and advisory groups, or any new requirements or guidelines they promulgate, may lengthen the regulatory review process, require us to perform additional studies, increase our development and manufacturing costs, lead to changes in regulatory pathways, positions and interpretations, delay or prevent approval and commercialization of our product candidates or lead to significant post-approval limitations or restrictions. As we advance our product candidates, we will be required to consult with the FDA and other regulatory authorities, and our product candidates will likely be reviewed by an FDA advisory committee. We also must comply with applicable requirements, and if we fail to do so, we may be required to delay or discontinue development of our product candidates. Delays or unexpected costs in obtaining, or the failure to obtain, the regulatory approval necessary to bring a potential product to market could impair our ability to generate sufficient product revenues to maintain our business.

Preliminary data and interim results we disclose may change as more patient data becomes available or as we make changes to our protocols or manufacturing processes, and such interim results and results from earlier studies may not be predictive of the final results, or of later studies or future clinical trials.

We may from time to time disclose results from preclinical testing or preliminary data or interim results from clinical studies of our product candidates. Such results from preclinical testing, process development and manufacturing activities, and clinical studies,

including interim clinical trial results as of specified data cutoff dates and results of earlier clinical studies with similar product candidates, are not necessarily predictive of future results, including later clinical trial results.

The results of our current and future clinical trials may differ from results achieved in earlier preclinical and clinical studies for a variety of reasons, including:

Additionally, some clinical trials of our product candidates performed to date were generated from open-label studies and are being conducted at a limited number of clinical sites on a limited number of patients. An “open-label” clinical trial is one where both the patient and investigator know whether the patient is receiving the investigational product candidate or either an existing approved drug or placebo. Most typically, open-label clinical trials test only the investigational product candidate and sometimes may do so at different dose levels. Open-label clinical trials are subject to various limitations that may exaggerate any therapeutic effect as patients in open-label clinical trials are aware when they are receiving treatment. Open-label clinical trials may be subject to a “patient bias” where patients perceive their symptoms to have improved merely due to their awareness of receiving an experimental treatment. In addition, open-label clinical trials may be subject to an “investigator bias” where those assessing and reviewing the physiological outcomes of the clinical trials are aware of which treatment regimen patients have received and may interpret the information of the treated group more favorably given this knowledge. Accordingly, the preliminary data from our Phase 1 clinical trials of certain of our product candidates may not be predictive of future clinical trial results for these or other product candidates when studied in a controlled environment or larger patient populations.

From time to time, we also publish interim, “top-line,” or preliminary data from our clinical studies based on a preliminary analysis of then-available data. Preliminary or interim data from clinical trials that we are conducting are subject to the risk that one or more of the clinical outcomes may materially change as patient enrollment continues, the duration of treatment increases and more patient data become available. For example, although we have, from time to time, reported positive interim clinical data for certain of our clinical programs, we may encounter dose-limiting toxicities or unacceptable side effects for these product candidates as dose escalation and expansion progresses in our clinical trials and additional patient data become available. Our preliminary or interim results and related conclusions also are subject to change following a more comprehensive review of the data related to the particular study or trial. Preliminary or “top-line” data also remain subject to audit and verification procedures that may result in the final data being materially different from the preliminary data we previously published. As a result, interim and preliminary data should be viewed with caution until the final data are available. Material adverse changes between preliminary, “top-line,” or interim data and final data could significantly harm our business prospects, financial condition and results of operations.

Results of clinical testing of any of our existing or future product candidates may fail to show the necessary safety and efficacy required for regulatory approval.

Before obtaining marketing approval from regulatory authorities for the sale of any of our product candidates, we must complete preclinical development and then conduct extensive clinical trials to demonstrate the safety and efficacy in humans of any such product candidates. Clinical testing is expensive, difficult to design and implement, can take many years to complete, and is uncertain as to outcome. A failure of one or more clinical trials can occur at any stage of testing. The outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. Our product candidates have a limited history of being evaluated in human clinical trials. Any of our product candidates may fail to show the desired safety and efficacy in later stages of clinical development despite having successfully advanced through initial clinical trials.

There is a high failure rate for drugs and biologics proceeding through clinical trials. A number of companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in later stage clinical trials even after achieving promising results in earlier stage clinical trials. Data obtained from preclinical and clinical activities are subject to varying interpretations, which may delay, limit, or prevent regulatory approval. In addition, regulatory delays or rejections may be encountered as a result of many factors, including changes in regulatory policy during the period of product development.

If our product candidates are ultimately not approved for any reason, our business, prospects, results of operations and financial condition would be adversely affected. In addition, the standard of care may change with the approval of new products for the same indications that we are studying.

Even if we obtain regulatory approval for a product candidate, our products will remain subject to regulatory scrutiny.

Any product candidate for which we obtain marketing approval, along with the manufacturing protocols, processes, materials and facilities, qualification testing, post-approval clinical data, labeling and promotional activities for such product, will be subject to continual and additional requirements of the FDA and other regulatory authorities. These requirements include submissions of safety and other post-marketing information, reports, registration and listing requirements, requirements relating to cGMP, applicable product tracking and tracing requirements, quality control, quality assurance and corresponding maintenance of records and documents, and recordkeeping. Even if marketing approval of a product candidate is granted, the approval may be subject to limitations on the indicated uses for which the product may be marketed or to conditions of approval, or contain requirements for costly post-marketing testing and surveillance to monitor the safety or efficacy of the product. Additionally, under the Food and Drug Omnibus Reform Act of 2022 (FDORA), sponsors of approved drugs and biologics must provide 6 months’ notice to the FDA of any changes in marketing status, such as the withdrawal of a drug, and failure to do so could result in the FDA placing the product on a list of discontinued products, which would revoke the product’s ability to be marketed. The FDA closely regulates the post-approval marketing and promotion of pharmaceutical and biological products to ensure such products are marketed only for the approved indications and in accordance with the provisions of the approved labeling. Later discovery of previously unknown problems with our product candidates, manufacturing operations, or failure to comply with regulatory requirements, may lead to various adverse conditions, including significant delays in bringing our product candidates to market and/or being precluded from manufacturing or selling our product candidates, any of which could significantly harm our business.

We may seek regenerative medicine advanced therapy (RMAT) designation for certain of our product candidates, but such designation may not actually lead to a faster development or regulatory review or approval process and we may be unable to obtain or maintain the benefits associated with such designation.

We may seek RMAT designation from the FDA for certain of our product candidates. A product candidate is eligible for RMAT designation if: (1) it is a cell therapy, therapeutic tissue engineering product, human cell or tissue product, or a combination product using any such therapies or products; (2) it is intended to treat, modify, reverse, or cure a serious or life-threatening disease or condition; and (3) there is preliminary clinical evidence that indicates that the product candidate has the potential to address unmet medical needs for such disease or condition. This program is intended to facilitate efficient development and expedite review of RMATs. A Biologics License Application (BLA) for a product candidate with RMAT designation may be eligible for priority review or accelerated approval through (1) surrogate or intermediate endpoints reasonably likely to predict long-term clinical benefit or (2) reliance upon data obtained from a meaningful number of sites. Benefits of such designation also include early interactions with the FDA to discuss any potential surrogate or intermediate endpoint to be used to support accelerated approval. A product candidate that has RMAT designation and is subsequently granted accelerated approval and is subject to post-approval requirements may fulfill such requirements through the submission of clinical evidence, clinical studies, patient registries, or other sources of real-world evidence, such as electronic health records; the collection of larger confirmatory data sets; or post-approval monitoring of all patients treated with such therapy prior to its approval. RMAT designation is within the discretion of the FDA. Accordingly, even if we believe one of our product candidates meets the criteria for RMAT designation, the FDA may disagree and instead determine not to grant such designation. In any event, the receipt of RMAT designation for a product candidate may not result in a faster development process, review or approval compared to product candidates considered for approval under conventional FDA procedures and does not assure ultimate approval by the FDA. In addition, even if one or more of our product candidates qualifies for RMAT designation, the FDA may later decide that the product candidate no longer meets the conditions for qualification.

We may rely on orphan drug status to develop and commercialize certain of our product candidates, but orphan drug designations may not confer marketing exclusivity or other expected commercial benefits and we may not be able to obtain orphan drug designations for our other product candidates.

We may rely on orphan drug exclusivity for product candidates that we may develop. Orphan drug status confers seven years of marketing exclusivity in the United States under the Federal Food Drug, and Cosmetic Act, and up to ten years of marketing exclusivity in Europe for a particular product in a specified indication, subject to certain conditions. However, we may be unable to obtain orphan drug designations for any of our product candidates that we are currently developing or may pursue. Even if we do obtain orphan drug designations and are the first to obtain marketing approval of our product candidates for the applicable indications, we will not be able to rely on these designations to exclude other companies from manufacturing or selling biological products using the same principal molecular structural features for the same indication beyond these timeframes. Furthermore, any marketing

exclusivity in Europe can be reduced from ten years to six years if the initial designation criteria have significantly changed since the market authorization of the orphan product.

For any product candidate for which we may be granted orphan drug designation in a particular indication, it is possible that another company also holding orphan drug designation for the same product candidate will receive marketing approval for the same indication before we do. If that were to happen, our applications for that indication may not be approved until the competing company’s period of exclusivity expires. Even if we are the first to obtain marketing authorization for an orphan drug indication in the United States, there are circumstances under which a competing product may be approved for the same indication during the seven-year period of marketing exclusivity, such as if the later product is shown to be clinically superior to our orphan product, or if the later product is deemed a different product than ours. Further, the seven-year marketing exclusivity would not prevent competitors from obtaining approval of the same product candidate as ours for indications other than those in which we have been granted orphan drug designation, or for the use of other types of products in the same indications as our orphan product.

We may seek designation for our cell programming technology as a designated platform technology, but we might not receive such designation, and even if we do, such designation may not lead to a faster development or regulatory review or approval process.

We may seek designation for our cell programming technology as designated platform technology. Under FDORA, a platform technology incorporated within or utilized by a drug or biological product is eligible for designation as a designated platform technology if (1) the platform technology is incorporated in, or utilized by, a drug approved under a BLA or NDA; (2) preliminary evidence submitted by the sponsor of the approved or licensed drug, or a sponsor that has been granted a right of reference to data submitted in the application for such drug, demonstrates that the platform technology has the potential to be incorporated in, or utilized by, more than one drug without an adverse effect on quality, manufacturing, or safety; and (3) data or information submitted by the applicable person indicates that incorporation or utilization of the platform technology has a reasonable likelihood to bring significant efficiencies to the drug development or manufacturing process and to the review process. A sponsor may request the FDA to designate a platform technology as a designated platform technology concurrently with, or at any time after, submission of an IND application for a drug that incorporates or utilizes the platform technology that is the subject of the request. If so designated, the FDA may expedite the development and review of any subsequent original BLA or NDA for a drug that uses or incorporates the platform technology. Even if we believe our cell programming technology meets the criteria for such designation, the FDA may disagree and instead determine not to grant such designation. In addition, the receipt of such designation for a platform technology does not ensure that a drug will be developed more quickly or lead to a faster FDA review or approval process and does not assure ultimate FDA approval of a drug. Moreover, the FDA may revoke a designation if the FDA determines that a designated platform technology no longer meets the criteria for such designation.

We may seek approval of our product candidate into RTOR. This program may not lead to a faster regulatory review or approval process and does not increase the likelihood that our product candidate(s) will receive marketing approval.

Participation in RTOR is voluntary. Our acceptance into RTOR does not guarantee or influence approval of our application, which is subject to the same statutory and regulatory requirements for approval as applications that are not included in RTOR. Although early approvals have occurred with applications selected for RTOR, this may not be the case for our application even if it is selected for RTOR. If at any time the FDA determines our participation in RTOR, if selected, is no longer appropriate, the FDA may rescind our acceptance and instruct us to follow routine submission procedures for marketing approval.

We may be subject to certain regulations, including federal and state healthcare fraud and abuse laws, physician payment transparency laws, anti-bribery and anti-corruption laws and health information privacy and security laws. Any actual or perceived failure to comply with these regulations could have a material adverse effect on our business and financial condition.

If we obtain FDA approval for any of our product candidates and begin commercializing those products in the United States, our operations may be subject to various federal and state healthcare laws, including, without limitation, fraud and abuse laws, false claims laws, data privacy and security laws, as well as transparency laws regarding payments or other items of value provided to healthcare providers. These laws may impact, among other things, our proposed sales, marketing and education programs. Additionally, we may be subject to state and foreign equivalents of such healthcare laws and regulations, some of which may be broader in scope and may apply regardless of the payor, as well as patient privacy regulation by both the federal government and the states in which we conduct our business. Because of the breadth of these laws and the narrowness of the statutory exceptions and safe harbors available, it is possible that some of our business activities could be subject to challenge and may not comply under one or more of such laws, regulations, and guidance. Law enforcement authorities are increasingly focused on enforcing fraud and abuse laws, and it is possible that some of our practices may be challenged under these laws. Efforts to ensure that our current and future business arrangements with third parties, and our business generally, will comply with applicable healthcare laws and regulations will involve substantial costs. If our operations, including our arrangements with physicians and other healthcare providers are found to be in violation of any of such laws or any other governmental regulations that apply to us, we may be subject to penalties, including,

without limitation, administrative, civil and criminal penalties, damages, fines, disgorgement, contractual damages, reputational harm, diminished profits and future earnings, the curtailment or restructuring of our operations, exclusion from participation in federal and state healthcare programs (such as Medicare and Medicaid), and imprisonment, as well as additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, any of which could adversely affect our ability to operate our business and our financial results. For more information regarding the risks related to such laws and regulations please see “Business – Government Regulation – Other Healthcare Laws and Compliance Requirements.”

The scope and enforcement of these laws is uncertain and subject to rapid change in the current environment of healthcare reform, especially in light of the lack of applicable precedent and regulations. Federal and state enforcement has led to a number of investigations, prosecutions, convictions and settlements in the healthcare industry. Ensuring that our internal operations and future business arrangements with third parties comply with applicable healthcare laws and regulations will involve substantial costs. It is possible that governmental authorities will conclude that our business practices do not comply with current or future statutes, regulations, agency guidance or case law involving applicable fraud and abuse or other healthcare laws and regulations.

The provision of benefits or advantages to physicians to induce or encourage the prescription, recommendation, endorsement, purchase, supply, order or use of medicinal products is prohibited in the European Union. The provision of benefits or advantages to physicians is also governed by the national anti-bribery laws of European Union Member States, such as the UK Bribery Act 2010. Infringement of these laws could result in substantial fines and individual imprisonment.

Payments made to physicians in certain European Union Member States must be publicly disclosed. Moreover, agreements with physicians often must be the subject of prior notification and approval by the physician’s employer, his or her competent professional organization and/or the regulatory authorities of the individual European Union Member States. These requirements are provided in the national laws, industry codes or professional codes of conduct, applicable in the European Union Member States. Failure to comply with these requirements could result in reputational risk, public reprimands, administrative penalties, fines or individual imprisonment.

A variety of risks associated with conducting research and clinical trials abroad and marketing our product candidates internationally could materially adversely affect our business.

We plan to develop and potentially commercialize our product candidates worldwide. Accordingly, we expect that we will be subject to additional risks related to operating in foreign countries, including:

These and other risks associated with our potential international operations may materially adversely affect our ability to attain or maintain profitable operations, which could have a material adverse effect on our business and results of operations.

We may decide to conduct clinical trials for our product candidates outside the United States, and the FDA may not accept data from trials conducted in such locations.

To date, we have only conducted clinical trials in the United States. However, we may in the future choose to conduct one or more of our clinical trials or include sites in current or future clinical trials outside the United States.

Although the FDA may accept data from sites or clinical trials outside the United States, acceptance of these data is subject to conditions imposed by the FDA. The FDA will generally not consider the data from a foreign clinical trial not conducted under an IND unless (i) the trial was well-designed and well-conducted in accordance with Good Clinical Practice (GCP) requirements, including requirements for the design, conduct, performance, monitoring, auditing, recording, analysis, and reporting of clinical trials in a way that provides assurance that the data and reported results are credible and accurate and that the rights, safety, and well-being of trial subjects are protected, and (ii) the FDA is able to validate the data from the trial through an onsite inspection, if necessary. In cases where data from foreign clinical trials are intended to serve as the sole basis for marketing approval in the U.S., the FDA will generally not approve the application on the basis of foreign data alone unless (i) the data are applicable to the U.S. population and U.S. medical practice; (ii) the trials were performed by clinical investigators of recognized competence; and (iii) the data may be considered valid without the need for an on-site inspection by the FDA or, if the FDA considers such as inspection to be necessary, the FDA is able to validate the data through an on-site inspection or other appropriate means. Additionally, the FDA’s clinical trial requirements, including sufficient size of patient populations and statistical powering must be met. Many foreign regulatory authorities have similar approval requirements. In addition, while these clinical trials or trial sites are subject to the applicable local laws where the trials are conducted, FDA acceptance of the data will depend on its determination that the trials or trial sites also complied with all applicable U.S. laws and regulations. There can be no assurance that the FDA will accept data from trials conducted outside the United States. If the FDA does not accept the data from any trial or trial site outside the United States, it would likely result in the need for additional trials, which would be costly and time-consuming and would delay or halt our development of the applicable product candidates.

Risks Related to Our Reliance on Third Parties

We are, and expect to continue to be, dependent on third parties to conduct some or all aspects of manufacturing of our product candidates for use in clinical trials and for commercial sale, if approved. Our business could be harmed if those third parties fail to perform satisfactorily.

While we currently manufacture clinical supplies of our iPSC-derived cell product candidates at our cGMP facilities located in San Diego, California, we also rely on third parties to manufacture certain components required for the manufacture of our product candidates, and we may rely on third parties to conduct some or all aspects of manufacturing of our product candidates for use in conducting later stage clinical trials and for commercial sale upon approval of any of our product candidates.

Reliance on third parties for manufacture of our product candidates and components utilized in manufacturing our product candidates entails certain risks, including reliance on the third party for regulatory compliance and quality assurance, the possibility that the third-party manufacturer does not maintain the financial, personnel or other resources to meet its obligations, the possibility that the third party fails to manufacture such components, or our product candidates or any products we may eventually commercialize, in accordance with our specifications, misappropriation of our proprietary information, including our trade secrets and know-how, and the possibility of termination of our manufacturing relationship by the third party, based on its own business priorities, at a time that is costly or damaging to us. In addition, the FDA and other regulatory authorities require that our product candidates and any products that we may eventually commercialize be manufactured according to cGMP, cGTP and similar jurisdictional standards. These requirements include, among other things, quality control, quality assurance and the maintenance of records and documentation. The FDA or similar foreign regulatory agencies may also implement new standards at any time, or change their interpretations and enforcement of existing standards for manufacture, packaging or testing of products. We have little control over our manufacturers’ compliance with these regulations and standards.

In some cases, the technical skills required to manufacture our product candidates may be unique or proprietary to a particular CMO, and we may have difficulty, or there may be contractual restrictions prohibiting us from, transferring such skills to a back-up or alternate supplier if needed, or we may be unable to transfer such skills at all. In addition, if we are required to change contract manufacturers for any reason, we will be required to verify that the new CMO maintains facilities and procedures that comply with quality standards and with all applicable regulations. We will also need to verify, such as through a manufacturing comparability study, that any new manufacturing process will produce our product candidate according to the specifications previously submitted to

the FDA or another regulatory authority. The delays associated with the verification of a new CMO could negatively affect our ability to develop product candidates or commercialize our products in a timely manner or within budget. In addition, changes in manufacturers often involve changes in manufacturing procedures and processes, which could require that we conduct bridging studies between our prior clinical supply used in our clinical trials and that of any new manufacturer. We may be unsuccessful in demonstrating the comparability of clinical supplies produced by different manufacturers, which could require the conduct of additional clinical trials.

Further, we depend in some instances on third party suppliers, including sole source suppliers, for the provision of reagents, materials, devices and equipment that are used by us and our third-party contract manufacturers in the production of our product candidates, including certain of our iPSC-derived cell therapy product candidates. Any disruption to or loss of supply from any of these suppliers could delay our clinical development and commercialization efforts, which would adversely affect our business, prospects, results of operations and financial condition.

We depend on strategic partnerships and collaboration arrangements for the development and commercialization of certain of our product candidates in certain indications or geographic territories, and if these arrangements are terminated or are unsuccessful, this could result in delays and other obstacles in the development, manufacture or commercialization of any of our product candidates and materially harm our results of operations.

Our strategy for fully developing and commercializing our product candidates is dependent upon maintaining our current arrangements and establishing new arrangements with research collaborators, corporate collaborators and other third parties. We currently have a corporate collaboration agreement with Ono; our collaboration with Janssen terminated effective April 2023. Our collaboration agreement with Ono provides for, among other things, research funding and significant future payments should certain development, regulatory and commercial milestones be achieved. Under our arrangement with Ono and any future corporate arrangements that we may form, our corporate collaborators may be responsible for:

As a result, we may not be able to conduct such corporate collaborations in the manner or on the time schedule we currently contemplate, which may negatively impact our business operations.

Our lack of control over the research funding for, and the development and commercialization of, certain of our product candidates being developed under the Ono Agreement and any other product candidates that we may develop under a future arrangement could cause delays or other difficulties in the development and commercialization of any of our product candidates, which may prevent completion of research and development activities and intended regulatory filings in a timely fashion, if at all. Because we expect to continue to rely on our current collaborator and to enter into new collaborations in the future, the development and commercialization of any of our product candidates could be substantially delayed, and our ability to receive future funding could be substantially impaired, if one or more of our current or future collaborators:

In addition, the termination of the Ono Agreement or any future strategic partnership or collaboration arrangement that we enter into may prevent us from receiving any milestone, royalty payment, sharing of profits, and other benefits under such agreement. Furthermore, disagreements with these parties could require or result in litigation or arbitration, which would be time-consuming and expensive. Any of these events could have a material adverse effect on our ability to develop and commercialize any of our product candidates and may adversely impact our business, prospects, financial condition, and results of operations.

Cell-based therapies depend on the availability of reagents and specialized materials and equipment which in each case are required to be acceptable to the FDA and foreign regulatory agencies, and such reagents, materials, and equipment may not be available to us on acceptable terms or at all. We rely on third-party suppliers for various components, materials and equipment required for the conduct of our clinical trials and the manufacture of our product candidates and do not have supply arrangements for certain of these components.

The development and manufacturing of our product candidates requires many reagents and other specialty materials and equipment, some of which are manufactured or supplied by small companies with limited resources and experience to support commercial biologics production. To date, we and our CMOs have purchased equipment, materials and disposables used for the manufacture of our existing product candidates from third-party suppliers. Some of these suppliers may not have the capacity to support commercial products manufactured under cGMP by biopharmaceutical firms or may otherwise be ill-equipped to support our needs. Reagents and other key materials from these suppliers may have inconsistent attributes and introduce variability into our manufactured product candidates, which may contribute to variable patient outcomes and possible adverse events. We rely on the general commercial availability of materials and equipment required for the manufacture of our product candidates, and do not have supply contracts with many of these suppliers and may not be able to obtain supply contracts with them on acceptable terms or at all. Even if we are able to enter into such contracts, we may be limited to a sole third-party for the supply of certain required components and equipment.

In addition, the clinical development of our product candidates depends on the availability of certain materials and agents used in our clinical trials. For example, we intend to develop certain of our product candidates as a combination therapy with other cancer therapies, such as monoclonal antibodies, requiring availability and use of these monoclonal antibodies in certain of our clinical trial protocols. Any failure or delays by us or by our clinical sites to obtain sufficient quantities of materials and agents required under our protocols, or other components and agents necessary for the conduct of our clinical trials, may delay our ability to enroll and treat patients in, or complete, our current or future clinical trials of our product candidates on time, if at all.

As a result of any public health crises, the business and operations of our suppliers and other third parties which produce agents and materials used in our clinical trials or manufacturing of our product candidates may be disrupted or delayed, and we in turn may experience disruptions or delays in our supply chain. A delay or inability to continue to source product or materials from any of these suppliers or third parties, which could be due to the impacts of any public health crises, natural disasters (including due to the effects of climate change), ongoing wars, including the wars between Russia and Ukraine and between Israel and Hamas, regulatory actions or requirements affecting the supplier, adverse financial or other strategic developments experienced by a supplier, labor disputes or shortages, unexpected demands, or quality issues, could adversely affect our ability to manufacture our product candidates and our ability to conduct clinical trials, which could significantly harm our business.

If we are required to change suppliers, or modify the components, equipment, materials or disposables used for the manufacture of our product candidates, we may be required to change our manufacturing operations or clinical trial protocols or to provide additional data to regulatory authorities in order to use any alternative components, equipment, materials or disposables, any of which could set back, delay, or increase the costs required to complete our clinical development and commercialization of our product candidates. Additionally, any such change or modification may adversely affect the safety, efficacy, stability, or potency of our product candidates, and could adversely affect our clinical development of our product candidates and harm our business.

We currently rely on third parties to conduct certain research and development activities and clinical trials of our product candidates. If these third parties do not successfully carry out their contractual duties or meet expected deadlines, we may not be able to timely develop, manufacture, obtain regulatory approval for or commercialize our product candidates and our business could be substantially harmed.

We rely upon third parties, including medical institutions, clinical investigators, and clinical research organizations (CROs) for the conduct of certain research and preclinical development activities, process development and manufacturing activities, and for the conduct, management, and supervision of clinical trials of our product candidates. We do not have direct control over the activities of these third parties, and may have limited influence over their actual performance. Our reliance on these third parties and CROs does not relieve us of our responsibilities to ensure that our clinical studies are conducted in accordance with the applicable protocol, legal and regulatory requirements and scientific standards.

We are responsible for complying, and we are responsible for ensuring that our third-party service providers and CROs comply, with applicable GCP for conducting activities for all of our product candidates in clinical development, including conducting our clinical trials, and recording and reporting data from these trials. Regulatory authorities enforce these regulations through periodic inspections of trial sponsors, principal investigators and trial sites. We cannot assure that upon inspection by a given regulatory authority, such regulatory authority will determine that any of our clinical trials comply with applicable GCP requirements. In addition, our registrational clinical trials must be conducted with product produced under applicable regulatory requirements.

If these third parties and CROs do not successfully carry out their contractual duties or obligations, meet expected deadlines or successfully complete activities as planned, or if the quality or accuracy of the research, preclinical development, process development, manufacturing, or clinical data they obtain is compromised due to the failure to adhere to applicable regulatory and manufacturing requirements or for other reasons, our research, preclinical development, process development and manufacturing activities, and clinical trials, and the development of our product candidates, may be extended, delayed or terminated, and we may not be able to obtain regulatory approval for or successfully commercialize our product candidates. Further, if our agreements with third parties or CROs are terminated for any reason, the development of our product candidates may be delayed or impaired, and we may be unable to advance our product candidates. As a result, our results of operations and the commercial prospects for our product candidates would be harmed, our costs could increase and our ability to generate revenues could be delayed or impaired.

If conflicts arise between us and our collaborators or strategic partners, these parties may act in a manner adverse to us and could limit our ability to implement our strategies.

If conflicts arise between our corporate or academic collaborators or strategic partners and us, the other party may act in a manner adverse to us and could limit our ability to implement our strategies. Some of our academic collaborators and strategic partners are conducting multiple product development efforts within each area that is the subject of the collaboration with us. Our collaborators or strategic partners, however, may develop, either alone or with others, products in related fields that are competitive with the products or potential products that are the subject of these collaborations. Competing products, either developed by the collaborators or strategic partners or to which the collaborators or strategic partners have rights, may result in the withdrawal of our collaborators’ or partners’ support for our product candidates.

Some of our collaborators or strategic partners could also become our competitors in the future. Our collaborators or strategic partners could develop competing products, preclude us from entering into collaborations with their competitors, fail to obtain timely regulatory approvals, terminate their agreements with us prematurely, or fail to devote sufficient resources to the development and commercialization of our product candidates. Any of these developments could harm our product development efforts.

Risks Related to Our Intellectual Property

If we are unable to protect our intellectual property, or obtain and maintain patent protection for our technology and product candidates, other companies could develop products based on our discoveries, which may reduce demand for our products and harm our business.

Our commercial success will depend in part on our ability to obtain and maintain intellectual property protection for our product candidates, the operations used to manufacture them and the methods for using them, and also for our cell programming technology in order to prevent third parties from making, using, selling, offering to sell or importing our product candidates or otherwise exploiting our cell programming approach. The scope of patent protection in the biotechnology and pharmaceutical field involves complex legal and scientific questions and can be uncertain. One aspect of the determination of patentability of our inventions depends on the scope and content of the “prior art,” information that was or is deemed available to a person of skill in the relevant art prior to the priority date of the claimed invention. There may be prior art of which we are not aware that may affect the patentability of our patent claims or, if issued, affect the validity or enforceability of a patent claim. Further, we may not be aware of all third-party intellectual property rights potentially relating to our product candidates or their intended uses, and as a result the impact of such third-party intellectual property rights upon the patentability of our own patents and patent applications, as well as the impact of such third-party intellectual

property upon our freedom to operate, is highly uncertain. Because patent applications in the United States and most other countries are confidential for typically a period of 18 months after filing, or may not be published at all, we cannot be certain that we were the first to file any patent application related to our product candidates. As a result, the issuance, scope, validity, enforceability, and commercial value of our patent rights are uncertain. We own and have exclusive licenses to patent portfolios for our product candidates and cell programming technology, although we cannot be certain that our existing patents and patent applications provide adequate protection or that any additional patents will issue to us with claims that provide adequate protection of our other product candidates. Further, we cannot predict the breadth of claims that may be enforced in our patents if we attempt to enforce them or if they are challenged in court or in other proceedings. If we are unable to secure and maintain protection for our product candidates and cell programming technology, or if any patents we obtain or license are deemed invalid and unenforceable, our ability to commercialize or license our technology could be adversely affected.

Others have filed, and in the future are likely to file, patent applications covering products and technologies that are similar, identical or competitive to ours or important to our business. Since patent applications in the United States and most other countries are confidential for a period of time after filing, and some remain so until issued, we cannot be certain that any patent application owned by a third party will not have priority over patent applications filed or in-licensed by us, or that we or our licensors will not be involved in interference, opposition, reexamination, review, reissue, post grant review or invalidity proceedings before U.S. or non-U.S. patent offices. The scope, validity or enforceability of our patents or the patents of our licensors may be challenged in such proceedings in either the courts or patent offices in the United States and abroad, and our business may be harmed if the coverage of our patents or the patents of our licensors is narrowed, or if a patent of ours or our licensors is judged invalid or unenforceable, in any such proceedings.

Furthermore, our intellectual property rights may be subject to a reservation of rights by one or more third parties. For example, the research resulting in certain of the patent rights and technology that we own or have licensed was funded in part by the U.S. government. As a result, the government has certain rights, including march-in rights, to such patent rights and technology. When new technologies are developed with government funding, the government generally obtains certain rights in any resulting patents, including a non-exclusive license authorizing the government to use the invention or to have others use the invention on its behalf. These rights may permit the government to disclose our information to third parties and to exercise march-in rights to use or allow third parties to use our technology. The government can exercise its march-in rights if it determines that action is necessary because we fail to achieve practical application of the government-funded technology, because action is necessary to alleviate health or safety needs, to meet requirements of federal regulations, or to give preference to U.S. industry. In addition, our rights in such inventions may be subject to certain requirements to manufacture products embodying such inventions in the United States. Any exercise by the government of such rights or by any third party of its reserved rights could harm our competitive position, business, financial condition, results of operations, and prospects.

We depend on our licensors to prosecute and maintain patents and patent applications that are material to our business. Any failure by our licensors to effectively protect these intellectual property rights could adversely affect our business and operations.

Certain rights to our key technologies and product candidates, including intellectual property relating to our iPSC technology, are licensed from third parties. As a licensee of third-party intellectual property, we rely on our licensors to file and prosecute patent applications and maintain patents, and otherwise protect the licensed intellectual property under some of our license agreements. We have not had and do not have primary control over these activities for certain of our licensed patents, patent applications and other intellectual property rights, and we cannot be certain that such activities will result in valid and enforceable patents and other intellectual property rights. Additionally, our licensors may have the right to control enforcement of our licensed patents or defense of any claims asserting the invalidity of these patents and we cannot be certain that our licensors will allocate sufficient resources or prioritize enforcement of such patents or defense of such claims to protect our interests in the licensed patents. Even if we are not a party to these legal actions, an adverse outcome could harm our business because it might prevent us from continuing to license intellectual property that we may need to operate our business.

If we fail to comply with our obligations under our license agreements, we could lose rights to our product candidates or key technologies.

We have obtained rights to develop, market and sell some of our product candidates through intellectual property license agreements with third parties. These license agreements impose various diligence, milestone payment, royalty and other obligations on us. In particular, under our Amended and Restated Exclusive License Agreement dated May 15, 2018 (Amended MSKCC License) with MSKCC, in the event a licensed product achieves a specified clinical milestone, MSKCC is eligible to receive from us certain milestone payments totaling up to $75.0 million based on the price of our common stock, where the amount of such payments owed to MSKCC is contingent upon certain increases in the price of our common stock following the date of achievement of such clinical milestone. If we fail to comply with our obligations under our license agreements, including any payment obligations, we could lose some or all of our rights to develop, market and sell products covered by these licenses, and our ability to form collaborations or

partnerships may be impaired. In addition, disputes may arise under our license agreements with third parties, which could prevent or impair our ability to maintain our current licensing arrangements on acceptable terms and to develop and commercialize the affected product candidates.

We are and may become involved in litigation or other proceedings from time to time relating to the enforcement or defense of patent and other intellectual property rights, which could cause us to divert our resources and could put our intellectual property at risk.

To prevent infringement or unauthorized use of our intellectual property, we have in the past, and may in the future, need to file infringement claims. For example, in May 2022, we filed a patent infringement lawsuit in the Southern District of California against Shoreline Biosciences, Inc. (see “Item 3. Legal Proceedings” for a more detailed description of this matter). When we pursue litigation to stop another party from using the inventions claimed in any patents we own or control, that party has the right to ask the court to rule that such patents are invalid or should not be enforced against that third party. In addition to patent infringement lawsuits, we may decide to file interferences, oppositions, ex parte reexaminations, post-grant review, or inter partes review proceedings before the U.S. Patent and Trademark Office (the USPTO) and corresponding foreign patent offices. Litigation and other proceedings relating to intellectual property are unpredictable and expensive and may consume time and resources and divert the attention of managerial and scientific personnel. Such litigations and proceedings could substantially increase our operating losses and reduce the resources available for research, development, and other activities. We may not have sufficient financial or other resources to adequately conduct such litigation or proceedings or may be required to divert such resources from our ongoing and planned research and development activities. Some of our competitors may be able to sustain the costs of such litigation or proceedings more effectively than we can because of their greater financial resources. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing or misappropriating or successfully challenging our intellectual property rights. Uncertainties resulting from the initiation and continuation of patent litigation or other proceedings could have a material adverse effect on our ability to compete in the marketplace.

There also is a risk that a court or patent office in such proceeding will decide that our patents or the patents of our licensors are not valid or are not enforceable, and that we do not have the right to stop the other party from using the inventions. Additionally, even if the validity of such patents is upheld, the court may refuse to stop the other party on the ground that such other party’s activities do not infringe our rights to such patents. If we are not successful in enforcing or defending our intellectual property, our competitors could develop and market products based on our discoveries and technologies, which may reduce the commercial viability of, and demand for, our product candidates and any future products.

We or our strategic partners may infringe the intellectual property rights of others, which may prevent or delay our product development efforts and stop us from commercializing, or increase the costs of commercializing, our product candidates.

Our success will depend, in part, on our ability to operate without infringing the proprietary rights of third parties. There is a substantial amount of litigation, both within and outside the United States, involving patent and other intellectual property rights in the biotechnology and pharmaceutical industries, including patent infringement lawsuits, interferences, oppositions, ex parte reexaminations, post-grant review, and inter partes review proceedings before the USPTO and corresponding foreign patent offices. Numerous U.S. and foreign issued patents and pending patent applications, which are owned by third parties, exist in the fields in which we are developing product candidates. As the biotechnology and pharmaceutical industries expand and more patents are issued, the risk increases that our product candidates may be subject to claims of infringement of the patent rights or misappropriation of other intellectual property rights of third parties.

We cannot be certain that any of our patent searches or analyses, including the identification of relevant patents, the scope of patent claims or the expiration of relevant patents, are complete or thorough, nor can we be certain that we have identified each and every third-party patent and pending application in the United States and abroad that is relevant to or necessary for the commercialization of our product candidates in any jurisdiction. The scope of a patent claim is determined by an interpretation of the law, the written disclosure in a patent and the patent’s prosecution history. Our interpretation of the relevance or the scope of a patent or a pending application may be incorrect, which may negatively impact our ability to market our products. We may incorrectly determine that our products are not covered by a third-party patent or intellectual property rights or may incorrectly predict whether a third-party’s pending application will issue with claims of relevant scope. Our determination of the expiration date of any patent in the United States or abroad that we consider relevant may be incorrect, which may negatively impact our ability to develop and market our product candidates. Our failure to identify and correctly interpret relevant patents may negatively impact our ability to develop and market our products.

We cannot guarantee that the manufacture, use or marketing of our existing product candidates or any other product candidates that we develop, or the use of our cell programming technology, will not infringe third-party patents. There may be third-party patents or patent applications with claims to materials, cell compositions, methods of manufacture or methods for treatment related to the use or manufacture of our product candidates. Our competitors may have filed, and may in the future file, patent applications covering

products and technologies similar to ours. Because patent applications can take many years to issue, there may be currently pending patent applications which may later result in issued patents that our product candidates may infringe. In addition, third parties may obtain patents in the future and claim that use of our technologies infringes upon these patents.

Third parties asserting their patent or other intellectual property rights against us may seek and obtain injunctive or other equitable relief, which could effectively block our ability to further develop and commercialize our product candidates or force us to cease some of our business operations. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of management and other employee resources from our business, cause development delays, and may impact our reputation. In the event of a successful claim of infringement against us, we may have to pay substantial damages, including treble damages and attorneys’ fees for willful infringement, obtain one or more licenses from third parties, pay royalties, or redesign our infringing products, which may be impossible on a cost-effective basis or require substantial time and monetary expenditure. In that event, we would be unable to further develop and commercialize our product candidates, which could harm our business significantly. Claims that we have misappropriated the confidential information or trade secrets of third parties could have a similar negative impact on our business.

We may not be successful in obtaining or maintaining necessary rights to product components and processes for development or manufacture of our product candidates which may cause us to operate our business in a more costly or otherwise adverse manner that was not anticipated.

We own or license from third parties certain intellectual property rights necessary to develop and manufacture our product candidates. The growth of our business will likely depend in part on our ability to acquire or in-license additional proprietary rights, including to advance our research or allow commercialization of our product candidates. In that event, we may be required to expend considerable time and resources to develop or license replacement technology. For example, our programs may involve additional technologies or product candidates that may require the use of additional proprietary rights held by third parties. Furthermore, other pharmaceutical or biotechnology companies and academic institutions may also have filed or are planning to file patent applications potentially relevant to our business. From time to time, in order to avoid infringing these third-party patents, we may be required to license technology from additional third parties to further develop or commercialize our product candidates. We may be unable to acquire or in-license any relevant third-party intellectual property rights, including any such intellectual property rights required to manufacture, use or sell our product candidates, that we identify as necessary or important to our business operations. We may fail to obtain any of these licenses at a reasonable cost or on reasonable terms, if at all, and as a result we may be unable to develop or commercialize the affected product candidates, which would harm our business. We may need to cease use of the compositions or methods covered by such third-party intellectual property rights, and may need to seek to develop alternative approaches or technology that do not infringe on such intellectual property rights which may entail additional costs and development delays, even if we were able to develop such alternatives, which may not be feasible. Even if we are able to obtain a license under such intellectual property rights, any such license may be non-exclusive, which may allow our competitors’ access to the same technologies licensed to us.

Additionally, we sometimes collaborate with academic institutions to accelerate our preclinical research or development under written agreements with these institutions. Typically, these institutions provide us with an option to negotiate a license to any of the institution’s rights in technology resulting from the collaboration. Regardless of such option, we may be unable to negotiate a license within the specified timeframe or under terms that are acceptable to us. If we are unable to do so, the institution may offer the intellectual property rights to other parties, potentially blocking our ability to pursue our program. If we are unable to successfully obtain rights to required third-party intellectual property or to maintain the existing intellectual property rights we have, we may have to abandon development of such program and our business and financial condition could suffer.

The licensing and acquisition of third-party intellectual property rights is a competitive practice, and companies that may be more established, or have greater resources than we do, may also be pursuing strategies to license or acquire third-party intellectual property rights that we may consider necessary or attractive in order to commercialize our product candidates. More established companies may have a competitive advantage over us due to their larger size and cash resources or greater clinical development and commercialization capabilities. In addition, it may be more costly for us to secure and maintain the necessary patent protection to block third parties from using our technology than to negotiate out-licenses or similar agreements with these parties to provide them with limited rights to use our technology. There can be no assurance that we will be able to successfully complete any such negotiations and ultimately acquire or maintain, on commercially viable terms, the rights to the intellectual property required for the successful development and commercialization of our product candidates.

Intellectual property rights do not necessarily address all potential threats to our competitive advantage.

The degree of future protection afforded by our intellectual property rights is uncertain because intellectual property rights have limitations and may not adequately protect our business or permit us to maintain our competitive advantage. For example:

Should any of these events occur, they could significantly harm our business, results of operations and prospects.

We may be subject to claims that our employees, consultants or independent contractors have wrongfully used or disclosed alleged trade secrets.

In conducting our business operations, we have obtained confidential and proprietary information from third parties. In addition, we employ individuals who were previously employed at other biotechnology or pharmaceutical companies, including our competitors or potential competitors. Although we try to ensure that our employees, consultants and independent contractors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or our employees, consultants or independent contractors have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of their former employers or other parties. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we could lose valuable intellectual property rights or personnel, which could adversely affect our business. Even if we are successful in defending against these claims, litigation could result in substantial costs and be a distraction to management.

We may be subject to claims challenging the inventorship of our patents and other intellectual property.

We may be subject to claims that former employees, collaborators, or other third parties have an interest in our patents or other intellectual property as an inventor or co-inventor. If we fail in defending any such claims, we may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, valuable intellectual property. We may also be subject to monetary damages, and any of these outcomes could have a material adverse impact on our business.

Proprietary information and invention assignment agreements with our employees and third parties may not prevent unauthorized disclosure of our trade secrets and other proprietary information.

In addition to the protection afforded by patents, we also rely upon unpatented trade secrets and improvements, proprietary know-how, and continuing technological innovation to develop and maintain our competitive position, which we seek to protect, in part, through confidentiality agreements with our collaborators, employees and consultants. We also have invention or patent assignment agreements with our employees and some, but not all, of our collaborators and consultants. Because we expect to rely on third parties in the development and manufacture of our product candidates, we must, at times, share trade secrets with them, which increases the possibility that a competitor will discover them or that our trade secrets will be misappropriated or disclosed.

Trade secrets, however, may be difficult to protect, and any disclosure, either intentional or unintentional, by our employees or third-party consultants and vendors that we engage to perform research, clinical trials or manufacturing activities, or misappropriation by third parties (such as through a cybersecurity breach) of our trade secrets or proprietary information could enable competitors to duplicate or surpass our technological achievements, thus eroding our competitive position in our market. Although we use reasonable efforts to protect our trade secrets, our employees or former employees, consultants, outside scientific advisors, contractors, and collaborators might intentionally or inadvertently disclose our trade secret information to competitors. In addition, competitors may otherwise gain access to our trade secrets or independently develop substantially equivalent information and techniques. Despite these efforts, any of these parties may breach the agreements and disclose our proprietary information, including our trade secrets, and we may not be able to obtain adequate remedies for such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor or other third-party, we would have no right to prevent them from using that technology or information to compete with us. Furthermore, the laws of some foreign countries do not protect proprietary rights to the same extent or in the same manner as the laws of the United States. As a result, we may encounter significant problems in protecting and defending our intellectual property both in the United States and abroad. If we are unable to prevent unauthorized material disclosure of our intellectual property to third parties, or misappropriation of our intellectual property by third parties, we will not be able to establish or maintain a competitive advantage in our market, which could materially adversely affect our business, operating results, and financial condition.

We may not be able to protect our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on our product candidates in all countries throughout the world would be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or importing products made using our inventions in and into the United States or other jurisdictions. Competitors may use our technologies in jurisdictions where we have not obtained patent protection to develop their own products and may also export infringing products to territories where we have patent protection, but enforcement is not as strong as that in the United States. These products may compete with any products that we may develop and commercialize, and our patents or other intellectual property rights may not be effective or sufficient to prevent them from competing.

Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets, and other intellectual property protection, particularly those relating to biotechnology and pharmaceutical products, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Proceedings to enforce our patent rights in foreign jurisdictions, whether or not successful, could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.

Changes in the patent law in the United States could diminish the value of patents in general, thereby impairing our ability to protect our product candidates and technology.

As is the case with other biotechnology companies, our success is heavily dependent on intellectual property rights, particularly patents. Obtaining and enforcing patents in the biotechnology industry involve both technological and legal complexity, and is therefore obtaining and enforcing biotechnology patents is costly, time-consuming and inherently uncertain. In addition, the United States has recently enacted and is currently implementing wide-ranging patent reform legislation. Recent U.S. Supreme Court rulings have narrowed the scope of patent protection available in certain circumstances and weakened the rights of patent owners in certain situations. In addition to increasing uncertainty with regard to our ability to obtain patents in the future, this combination of events has

created uncertainty with respect to the value of patents, once obtained. Depending on decisions by the U.S. Congress, the federal courts, and the USPTO, the laws and regulations governing patents could change in unpredictable ways that would weaken our ability to obtain new patents or to enforce our existing patents and patents that we might obtain in the future.

The term of our patents may not be sufficient to effectively protect our market position and products.

Patents have a limited lifespan. In the United States, the natural expiration of a patent is generally 20 years after it is filed. Various extensions may be available; however, the life of a patent, and the protection it affords, is limited. Even if we obtain patents covering our product candidates, once the patent life has expired for a product, we may be open to competition from other products. If the lives of our patents are not sufficient to effectively protect our products and business, our business and results of operations will be adversely affected.

Risks Related to the Commercialization of Our Product Candidates

We do not have experience marketing any product candidates and do not have a sales force or distribution capabilities, and if our products are approved, we may be unable to commercialize them successfully.

We currently have no experience in marketing and selling therapeutic products, including obtaining and maintaining adequate pricing and reimbursements. If any of our product candidates are approved for marketing, we intend to establish marketing and sales capabilities internally or we may selectively seek to enter into partnerships with other entities to utilize their marketing and distribution capabilities. If we are unable to develop adequate marketing and sales capabilities on our own or effectively partner with third parties, our ability to generate product revenues will suffer.

The commercial success of our product candidates will depend upon the degree of market acceptance by physicians, patients, third-party payers and others in the medical community.

The commercial success of our products, if approved for marketing, will depend in part on the medical community, patients and third-party payers accepting our product candidates as effective and safe. If these products do not achieve an adequate level of acceptance, we may not generate significant product revenue and may not become profitable. For example, in November 2023, the FDA announced that it would be conducting an investigation into reports of T-cell malignancies following BCMA-directed or CD19-directed autologous CAR T-cell immunotherapies following reports of T-cell lymphoma in patients receiving these therapies. In January 2024, the FDA determined that new safety information related to T-cell malignancies should be included in the labeling with boxed warning language on these malignancies for all BCMA- and CD19-directed genetically modified autologous T-cell immunotherapies. FDA’s investigation into CAR T-cell therapies and other similar actions could result in increased government regulation, unfavorable public perception and publicity, stricter labeling requirements for those product candidates that are approved, and a decrease in demand for any such product candidates. The degree of market acceptance of our products, if approved for marketing, will depend on a number of factors, including:

The patient populations targeted by our autoimmune product candidates are also typically not at risk of near-term death, even if they may suffer life-threatening symptoms, so those patients will need to deem the benefits of cell therapy to be worth the risk of unknown potential adverse side effects. Our success in this space will depend upon physicians who specialize in the treatment of

autoimmune diseases targeted by our product candidates prescribing treatments that involve the use of our product candidates in lieu of, or in addition to, existing treatments with which they are more familiar and for which greater clinical data may be available.

Even if a potential product displays a favorable efficacy and safety profile in preclinical studies and clinical trials, market acceptance of the product will not be known until after it is launched. Any failure to achieve market acceptance for our product candidates will harm our business, results and financial condition.

We expect to face uncertainty regarding the pricing of our existing product candidates and any other product candidates that we may develop. If pricing policies for our product candidates are unfavorable, our commercial success will be impaired.

Due to the novel nature of our cellular immunotherapy product candidates, we face significant uncertainty as to the pricing of any such products for which we may receive marketing approval. While we anticipate that pricing for any cellular immunotherapy product candidates that we develop will be relatively high due to their anticipated use in the prevention or treatment of life-threatening diseases where therapeutic options are limited, the biopharmaceutical industry has recently experienced significant pricing pressures. In particular, drug pricing and other healthcare costs continue to be subject to intense political and societal pressures, which we anticipate will continue and escalate on a global basis. These pressures may result in harm to our business and reputation, cause our stock price to decline or experience periods of volatility and adversely affect results of operations and our ability to raise funds.

The insurance coverage and reimbursement status of newly-approved products is uncertain. Failure to obtain or maintain adequate coverage and reimbursement for our product candidates could limit our product revenues.

Our ability to commercialize any of our product candidates successfully will depend in part on the availability of coverage and reimbursement for these products from third-party payors, including government health administration authorities, private health insurers, and other managed care organizations. The availability and extent of reimbursement by governmental and private payors is essential for most patients who generally rely on third-party payors to reimburse all or part of the costs of their care, including treatments such as cellular immunotherapy. Because our product candidates represent new approaches to the treatment of cancer, there is significant uncertainty as to the insurance coverage and reimbursement status of any product candidates for which we may receive regulatory approval. In the United States, the principal decisions about reimbursement for new medicines are typically made by the Centers for Medicare & Medicaid Services (CMS), an agency within the U.S. Department of Health and Human Services. CMS decides whether and to what extent a new medicine will be covered and reimbursed under Medicare, and private payors tend to follow CMS determinations to a substantial degree. If reimbursement or insurance coverage is not available for our product candidates, or is available only to limited levels, we may not be able to successfully commercialize our product candidates. Even if coverage is provided, the approved reimbursement amount may not be sufficient to allow us to establish or maintain pricing to generate income. Factors payors consider in determining reimbursement are based on whether the product is: (i) a covered benefit under its health plan; (ii) safe, effective and medically necessary; (iii) appropriate for the specific patient; (iv) cost-effective; and (v) neither experimental nor investigational. For more information regarding the risks related to insurance coverage and reimbursement, see “Business - Government Regulation - Coverage and Reimbursement.”

In addition, reimbursement agencies in foreign jurisdictions may be more conservative than those in the United States. Accordingly, in markets outside the United States, the reimbursement for our products may be reduced compared with the United States and may be insufficient to generate commercially reasonable revenues and profits. Moreover, increasing efforts by governmental and third-party payors, in the United States and abroad, to cap or reduce healthcare costs may cause such organizations to limit both coverage and level of reimbursement for new products approved and, as a result, they may not cover or provide adequate payment for our product candidates. Failure to obtain or maintain adequate reimbursement for any products for which we receive marketing approval will adversely affect our ability to achieve commercial success, and could have a material adverse effect on our operating results, our ability to raise capital needed to commercialize products, and our overall financial condition.

If the market opportunities for our product candidates are restricted or smaller than we believe they are, our revenues may be adversely affected and our business may suffer. Because the target patient populations of our product candidates may be small and variable, we must be able to successfully identify patients and capture a significant market share to achieve and maintain profitability.

We focus our research and development on product candidates for rare diseases, including cancer and autoimmune diseases. The FDA often approves new therapies initially for use in patients with relapsed or refractory disease. We expect to initially seek approval of our product candidates in these settings. Subsequently, for those products that prove to be sufficiently beneficial, if any, we would expect to seek approval in earlier lines of treatment. There is no guarantee that our product candidates, even if approved, would be approved for earlier lines of therapy, and, prior to any such approvals, we will have to conduct additional clinical trials, including potentially comparative trials against approved therapies. Certain of our product candidates also target similar patient populations as autologous cell therapy product candidates, including approved autologous CAR T products. Our therapies may not be as safe and

effective as approved autologous CAR T therapies and as a result, such product candidates may only be approved for patients who are ineligible for autologous CAR T therapy.

Our projections of the number of people who have or will have the diseases we may be targeting, as well as the subset of patients with these cancers in a position to receive second or later lines of therapy and who have the potential to benefit from treatment with our product candidates, may prove to be incorrect. Further, new studies may change the estimated incidence or prevalence of these diseases. The number of patients in the United States, Europe and elsewhere may turn out to be lower than expected, or the potentially addressable patient population for our product candidates may be limited or may not be amenable to treatment with our product candidates, all of which would adversely affect our results of operations and our business. Additionally, because our target patient populations may be small and variable, we may never achieve profitability without capturing a significant market share or obtaining regulatory approval for additional indications for our products.

Healthcare legislative or regulatory reform measures may have a negative impact on our business and results of operations.

In the United States and some foreign jurisdictions, there have been, and continue to be, several legislative and regulatory changes and proposed changes regarding the healthcare system that could prevent or delay marketing approval of product candidates, restrict or regulate post-approval activities, and affect our ability to profitably sell any product candidates for which we obtain marketing approval. Payors, whether domestic or foreign, or governmental or private, are developing increasingly sophisticated methods of controlling healthcare costs. In both the United States and certain foreign jurisdictions, there have been a number of legislative and regulatory changes to the health care system that could impact our ability to sell our products profitably. Additional changes that may affect our business include those governing enrollment in federal healthcare programs, reimbursement changes, rules regarding prescription drug benefits under the health insurance exchanges and fraud and abuse and enforcement. Continued implementation of the Affordable Care Act (ACA) and the passage of additional laws and regulations may result in the expansion of new programs such as Medicare payment for performance initiatives, and may impact existing government healthcare programs, such as by improving the physician quality reporting system and feedback program. For more information regarding the risks related to such recently enacted and future legislation please see “Business – Government Regulation – Healthcare Reform and Other Regulatory Changes.”

There has been increasing legislative and enforcement interest in the United States with respect to drug pricing practices.  Specifically, there has been heightened governmental scrutiny over the manner in which manufacturers set prices for their marketed products, which has resulted in several U.S. Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription drugs under Medicare, and review the relationship between pricing and manufacturer patient programs.

The continuing efforts of the government, insurance companies, managed care organizations and other payers of healthcare services to contain or reduce costs of healthcare may adversely affect:

We expect that additional U.S. federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that the U.S. federal government will pay for healthcare drugs and services, which could result in reduced demand for our drug candidates or additional pricing pressures. Individual states in the United States have also become increasingly active in passing legislation and implementing regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain drug access and marketing cost disclosure and transparency measures, and designed to encourage importation from other countries and bulk purchasing. Legally mandated price controls on payment amounts by third-party payors or other restrictions could harm our business, financial condition, results of operations and prospects. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs. This could reduce the ultimate demand for our drugs or put pressure on our drug pricing, which could negatively affect our business, financial condition, results of operations and prospects.

Risks Related to Our Business and Industry

The success of our existing product candidates is substantially dependent on developments within the field of cellular immunotherapy, and specifically developments relating to the use of pluripotent or genome edited cells for the manufacture of cellular therapeutics, the majority of which are beyond our control.

Our product candidates are designed and are being developed as therapeutic entities for use as cellular immunotherapies, and all of our current product candidates are based on our novel iPSC product platform. Additionally, some of our product candidates utilize novel genome editing technologies. To date, there is limited clinical trial experience testing iPSC-derived therapeutic product candidates using genome edited cells. The fields of cellular and genome edited therapies are evolving, and as more therapeutic product candidates derived from pluripotent and genome edited cells are reviewed by regulatory authorities, regulatory authorities may impose additional requirements for approval that were not previously anticipated. There have also been several significant adverse events from gene therapy treatments in the past, including reported cases of leukemia and death. Additionally, in November 2023, the FDA announced that it would be conducting an investigation into reports of T-cell malignancies following BCMA-directed or CD19-directed autologous CAR T-cell immunotherapies following reports of T-cell lymphoma in patients receiving these therapies. In January 2024, the FDA determined that new safety information related to T-cell malignancies should be included in the labeling with boxed warning language on these malignancies for all BCMA- and CD19-directed genetically modified autologous T-cell immunotherapies. There can be no assurance that any product candidates developed from or related to our iPSC product platform or any of our research programs will not cause severe or undesirable side effects or result in significant delays or unanticipated costs, or that such development problems can be solved. Any adverse developments in the fields of cellular immunotherapy or genome edited therapy, such as FDA’s investigation into CAR T-cell therapies and other similar actions could negatively affect our ability to develop and commercialize our product candidates.

We face intense competition in an environment of rapid technological and scientific progress from other biotechnology and pharmaceutical companies that are commercializing, have developed or may develop product candidates for the treatment of the diseases that we may target, including companies developing novel therapies and platform technologies. If these companies develop product candidates or platform technologies more rapidly than we do, if their commercialized products or product candidates are more effective, more cost effective, or have fewer side effects, or if they compete in various other aspects of our business, our ability to develop and successfully commercialize product candidates and to execute on our business plans will be adversely affected.

The biotechnology and pharmaceutical industries are intensely competitive and characterized by rapid and significant innovation, particularly in the areas of immune-oncology and the development and commercialization of cell therapies. We compete with a variety of large pharmaceutical companies, multinational biopharmaceutical companies, other biopharmaceutical companies and specialized biotechnology companies, as well as technology and/or therapeutics being developed at universities and other research institutions. Many of our competitors have greater financial and other resources, such as larger research and development staff, more experienced manufacturing organizations and facilities and greater sales and marketing organizations. Third parties are commercializing, have developed, are developing or may develop product candidates, platform technologies and processes that compete with ours. Competitive therapeutic treatments include those that have already been approved and accepted by the medical community, as well as novel treatments that are currently in preclinical or clinical development or may otherwise enter the market. We believe that a significant number of product candidates are currently under development, including various cellular immunotherapies as well as multifunctional targeted antibodies, such as bi-specific and tri-specific T-cell engagers, which may become commercially available in the future for the treatment of indications, including a variety of cancers, for which we are developing or may try to develop our product candidates. Should one or more of these competing product candidates or other competing product candidates of which we are not aware receive regulatory approval or otherwise achieve clinical or commercial success, our regulatory strategy could be impaired, our ability to obtain regulatory approval could be delayed or prevented, or the market for our products may be reduced or eliminated, thereby harming or preventing our commercial success.

Even if we successfully obtain approval for any product candidate, we will face competition based on many different factors, including the relative safety and efficacy of our product candidates, the actual or perceived quality of patient life while undergoing treatment with our product candidates, the ease with which our product candidates can be administered, the timing and scope of regulatory approvals for these product candidates, the availability and cost of manufacturing, marketing and sales capabilities, pricing, reimbursement coverage and patent positions, and the relative prioritization of our product candidates by physicians and healthcare providers among available therapies. Competing products and product candidates could present superior treatment alternatives, including by being more effective, safer, less expensive or marketed and sold more effectively than any products we may develop. Competitive products and product candidates may also make any product we develop obsolete or noncompetitive before we recover the expense of developing and commercializing such product. We could also face competition from other companies for collaboration partners, employees, advisors and service providers, which could negatively impact our ability to execute our business plans.

Mergers and acquisitions in the pharmaceutical and biotechnology industries may result in even more resources being concentrated among a smaller number of our competitors. Smaller or early-stage companies may also prove to be significant competitors, particularly through collaborative arrangements with large and established companies. These competitors also compete with us in recruiting and retaining qualified scientific and management personnel and establishing clinical trial sites and patient registration for clinical trials, as well as in acquiring technologies complementary to, or necessary for, our programs. Our commercial opportunity could be reduced or eliminated if our competitors develop and commercialize products that are safer, more effective, have fewer or less severe side effects, are more convenient, or are less expensive or more commercially viable than any products that we may develop. Furthermore, currently approved products could be discovered to have application for treatment of our targeted disease indications or similar indications, which could give such products significant regulatory and market timing advantages over our product candidates. Our competitors also may obtain FDA or other regulatory approval for their products more rapidly than we may obtain approval for ours and may obtain orphan product exclusivity from the FDA for indications that we are targeting, which could result in our competitors establishing a strong market position before we are able to enter the market. Additionally, products or technologies developed by our competitors may render our product candidates uneconomical or obsolete and we may not be successful in marketing those product candidates, once approved, against competitors.

Our ability to compete effectively with other biotechnology and pharmaceutical companies depends on our ability to distinguish our company and our product candidates from our competitors and their product candidates.

Some of our competitors may have, or new competitors or alliances may emerge that have, greater name and brand recognition, greater market share, a larger customer base, more widely adopted proprietary technologies, greater marketing expertise, larger sales forces, or significantly greater resources than we do and may be able to offer solutions competitive with ours at a more attractive price than we can. Further, our current or potential competitors may be acquired by third parties with greater available resources. As a result, our competitors may be able to respond more quickly and effectively than we can to new or changing opportunities, technologies, standards or customer requirements and may have the ability to initiate or withstand substantial price competition. In addition, our competitors may in the future establish cooperative relationships with vendors of complementary products, technologies or services to increase the availability of their solutions in the marketplace. Our competitors could also be better positioned to serve certain segments of our market, which could create additional price pressure. In light of these factors, even if any products that we may develop are more effective than those of our competitors, current or potential customers may accept competitive products in lieu of purchasing our products. If we are unable to successfully compete, our business, financial condition, and results of operations could be materially and adversely affected.

The loss of any member of our senior management team or our inability to attract and retain key personnel and consultants could adversely affect our business.

We may not be able to retain or attract qualified management, finance, scientific and clinical personnel and consultants due to the intense competition for a limited number of qualified personnel and consultants among biotechnology, pharmaceutical and other businesses. The loss of any members of our senior management team could adversely impact our operations if we experience difficulties in recruiting and hiring qualified successors. We may also experience difficulties in attracting or retaining personnel with sufficient experience and skills in the complex and emerging field of cellular therapeutic development and manufacture to support our ongoing and planned clinical development activities. We currently rely, and for the foreseeable future will continue to rely, in substantial part on certain independent organizations, advisors and consultants. There can be no assurance that the services of independent organizations, advisors and consultants will continue to be available to us on a timely basis when needed, or that we can find qualified replacements. We may also be subject to penalties or other liabilities if we misclassify employees as consultants. In addition, if we are unable to effectively manage our outsourced activities or if the quality or accuracy of the services provided by consultants is compromised for any reason, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval of our product candidates or otherwise advance our business. There can be no assurance that we will be able to manage our existing consultants or find other competent outside contractors and consultants on economically reasonable terms, or at all.

Many of the biotechnology and pharmaceutical companies that we compete against for qualified personnel have greater financial and other resources and different risk profiles than we do. We may be required to provide compensation in excess of historical levels in order to recruit and retain personnel in the current market. If we are not able to retain and attract necessary personnel and consultants to perform the requisite operational roles and accomplish our business objectives, we may experience constraints that will significantly impede the achievement of our development objectives, our ability to raise additional capital and our ability to implement our business strategy.

If we engage in an acquisition, reorganization or business combination, we will incur a variety of risks that could adversely affect our business operations or our stockholders.

From time to time, we have considered, and we will consider in the future, strategic business initiatives intended to further the expansion and development of our business. These initiatives may include acquiring businesses, technologies or products or entering into business combinations with other companies. If we pursue such a strategy, we could, among other things:

Although we intend to evaluate and consider acquisitions, reorganizations and business combinations in the future, we have no agreements or understandings with respect to any acquisition, reorganization or business combination at this time.

We face potential product liability exposure far in excess of our limited insurance coverage.

The use of our product candidates in clinical trials, and the sale of any products for which we obtain marketing approval, exposes us to the risk of product liability claims. Product liability claims might be brought against us by participants in clinical trials, hospitals, medical centers, healthcare providers, pharmaceutical companies, and consumers, or by others selling, manufacturing or otherwise coming into contact with our product candidates. We carry product liability insurance and we believe our product liability insurance coverage is sufficient in light of our current clinical programs. In addition, if and when we obtain marketing approval for product candidates, we intend to expand our insurance coverage to include the sale of commercial products; however, we may be unable to obtain insurance coverage for any approved products on commercially reasonable terms or in sufficient amounts to protect us against losses due to liability.

On occasion, large judgments have been awarded in class action lawsuits based on drugs or medical treatments that had unanticipated adverse effects. In addition, under some of our agreements with clinical trial sites, we are required to indemnify the sites and their personnel against product liability and other claims. A successful product liability claim, or a series of claims, brought against us or any third parties whom we are required to indemnify could cause our stock price to decline and, if judgments exceed our insurance coverage, could adversely affect our results of operations and business.

Patients with the diseases targeted by our product candidates are often already in severe and advanced stages of disease and have both known and unknown significant pre-existing and potentially life-threatening health risks. During the course of treatment, patients may suffer adverse events, including death, for a variety of reasons. Such events, whether or not resulting from our product candidates, could subject us to costly litigation, require us to pay substantial amounts of money to injured patients, delay, negatively affect or end our opportunity to receive or maintain regulatory approval to market our products, or require us to suspend or abandon our commercialization efforts. Even in a circumstance in which we do not believe that an adverse event is related to our products, the investigation into the circumstance may be time-consuming or inconclusive. These investigations may interrupt our development and commercialization efforts, delay our regulatory approval process, or impact and limit the type of regulatory approvals our product candidates receive or maintain. As a result of these factors, a product liability claim, even if successfully defended, could have a material adverse effect on our business, financial condition or results of operations.

Our insurance policies are expensive and protect us from only some risks, which leaves us exposed to significant uninsured liabilities.

We do not carry insurance for all categories of risk to which our business is or may be exposed. Some of the policies we maintain include general liability, product liability, property, employee benefits liability, employment practices, workers’ compensation, cybersecurity, directors’ and officers’ insurance, and umbrella. We do not know, however, if we will be able to maintain insurance coverage at a reasonable cost or in sufficient amounts or scope to protect us against losses. Even if we obtain insurance, a claim could exceed the amount of our insurance coverage or it may be excluded from coverage under the terms of the policy. Any significant uninsured liability may require us to pay substantial amounts, which would adversely affect our cash position and results of operations.

Our employees or third party service providers may engage in misconduct or other improper activities, including noncompliance with regulatory standards and requirements and insider trading.

We are exposed to the risk of employee or third party service provider fraud or other misconduct. Misconduct by employees or third party service providers could include intentional failures to comply with the regulations of the FDA or foreign regulators, to provide accurate information to the FDA or foreign regulators, to comply with healthcare fraud and abuse laws and regulations in the United States and abroad, to report financial information or data accurately or to disclose unauthorized activities to us. In particular, sales, marketing and business arrangements in the healthcare industry are subject to extensive laws and regulations intended to prevent fraud, misconduct, kickbacks, self-dealing and other abusive practices. Employee or third party service provider misconduct could also involve the improper use of information obtained in the course of clinical trials, which could result in regulatory sanctions and cause serious harm to our reputation. If any actions alleging such conduct are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant effect on our business, including the imposition of significant fines or other sanctions.

Our business could be negatively affected by cyberattacks or a deficiency in our cybersecurity.

A cyberattack or similar incident could occur and result in information theft, data corruption, operational disruption, damage to our reputation, or financial loss. We are increasingly dependent on information technology systems and infrastructure, including mobile technologies, to operate our business. Our technologies, systems, networks, or other proprietary information, and those of our vendors, suppliers and other business partners, may become the target of cyberattacks or information security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss, or destruction of proprietary and other information, or could otherwise lead to the disruption of our business operations. The risk of a security breach or disruption, particularly through cyberattacks or cyber intrusion, including by computer hackers, foreign governments, and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. Moreover, certain cyber incidents, such as surveillance, may remain undetected for an extended period and could lead to disruptions in critical systems or the unauthorized release of confidential or otherwise protected information. These events could lead to financial loss due to remedial actions, loss of business, disruption of operations, damage to our reputation, or potential liability. Our systems and insurance coverage for protecting against cybersecurity risks may not be sufficient. Furthermore, as cyberattacks continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our protective measures or to investigate and remediate any vulnerability to cyberattacks.

We face risks of potential liability related to the privacy of personal information, including health information we utilize in the development of our products, as well as information we obtain from clinical trials sponsored by us from research institutions and directly from individuals.

We and our partners and vendors may be subject to various federal, state, and foreign data protection laws and regulations (i.e., laws and regulations that address privacy and data security). In the United States, numerous federal and state laws and regulations, including federal health information privacy laws, state data breach notification laws, state health information privacy laws, and federal and state consumer protection laws (e.g., Section 5 of the Federal Trade Commission Act), that govern the collection, use, disclosure and protection of health-related and other personal information could apply to our operations or the operations of our collaborators, including the federal Health Insurance Portability and Accountability Act of 1996 (HIPAA) and privacy and security requirements under HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 (HITECH). Depending on the facts and circumstances, we could be subject to civil, criminal, and administrative penalties if we knowingly obtain, use, or disclose individually identifiable health information maintained by a HIPAA-covered entity in a manner that is not authorized or permitted by HIPAA. There is no certainty that all of our employees, agents, suppliers, manufacturers, contractors, or collaborators, or those of our affiliates, will comply with all applicable laws and regulations, particularly given the high level of complexity of these laws. Even when HIPAA does not apply, failing to take appropriate steps to keep consumers’ personal information secure may constitute a violation of the Federal Trade Commission Act. In addition, certain of the materials we use as starting material in our iPSC-derived product candidates are derived from human sources, which potentially contain sensitive identifiable personal information regarding the donor. In addition, in conducting our clinical trials, we may maintain sensitive identifiable personal information, including health information, that we receive throughout the clinical trial process, in the course of our research collaborations, and directly from individuals (or their healthcare providers) who enroll in our clinical trials. As such, we may become subject to further obligations under HIPAA. Our collection of personal information generally (e.g., of employees currently and/or of patients in the future) may subject us to state data privacy laws governing the processing of personal information and requiring notification of affected individuals and state regulators in the event of a breach of such personal information. These state laws include the California Consumer Privacy Act , as amended by the California Privacy Rights Act (the CCPA), which establish data privacy rights for residents of the State of California, with corresponding obligations on businesses related to transparency, deletion rights, and opt-out of the selling or sharing of personal information, and grants a private right of action for individuals in the event of certain security breaches. Similar laws relating to data privacy and security have passed in several other states, which may

have potentially conflicting requirements that would make compliance challenging, require us to expend significant resources to come into compliance, and restrict our ability to process certain personal information.

Certain state laws may be more stringent or broader in scope than the CCPA, or offer greater individual rights, with respect to confidential, sensitive and personal information than federal, international or other state laws, and such laws may differ from each other, which may complicate compliance efforts.

An increasing number of foreign data protection laws, regulations and industry standards may also apply to personal information we obtain from individuals outside of the United States. For example, the GDPR, imposes strict requirements for processing the personal data of individuals within the EEA and UK, including health-related data, and on the transfer of personal data out of the EEA and UK to non-adequate territories such as the United States; any inability to transfer personal data from the EEA and UK to the United States in compliance with data protection laws may impede our ability to conduct trials and may adversely affect our business and financial position. Failure to comply with the requirements of the GDPR may result in potential fines for companies of up to the greater of €20 million (£17.5 million for the UK GDPR) or 4% of annual global revenue and other administrative penalties. In addition, under the GDPR, companies may face private litigation related to processing of personal data brought by classes of data subjects or consumer protection organizations authorized at law to protect their interests. Although the EU GDPR and the UK GDPR currently impose substantially similar obligations, it is possible that over time the UK GDPR could become less aligned with the EU GDPR, particularly with the introduction of the new Data Reform Bill into the UK legislative process. In addition, EEA Member States have adopted national laws to supplement the EU GDPR, which may partially deviate from the EU GDPR, and the competent authorities in the EEA Member States may interpret EU GDPR obligations slightly differently from country to country, such that we do not expect to operate in a uniform legal landscape in the EEA and UK with respect to data protection regulations. The potential of the respective provisions and enforcement of the EU GDPR and UK GDPR further diverging in the future creates additional regulatory challenges and uncertainties for us. The lack of clarity on future UK laws and regulations and their interaction with EU laws and regulations could add legal risk, uncertainty, complexity and compliance cost to the handling of European personal data and our privacy and data security compliance, and could require us to amend our processes and procedures to implement different compliance measures for the UK and the EEA.

We are likely to be required to expend significant capital and other resources to ensure ongoing compliance with applicable data privacy and security laws. Claims that we have violated individuals’ privacy rights or breached our contractual obligations, even if we are not found liable, could be expensive and time-consuming to defend, and could result in adverse publicity that could harm our business. Moreover, even if we take all necessary action to comply with legal and regulatory requirements, we could be subject to a data breach or other unauthorized access of personal information, which could subject us to fines and penalties, as well as litigation and reputational damage. If we fail to keep apprised of and comply with applicable international, federal, state, or local regulatory requirements, we could be subject to a range of regulatory actions that could affect our or any collaborators’ ability to seek to commercialize our clinical candidates. Any threatened or actual government enforcement action or litigation could also generate adverse publicity, damage our reputation, result in liabilities, fines and loss of business, and require that we devote substantial resources that could otherwise be used in other aspects of our business.

We make public statements about our use and disclosure of personal information through our privacy policy information provided on our internet platform and press statements. Although we endeavor to comply with our public statements and documentation, we may at times fail to do so or be alleged to have failed to do so. Moreover, despite our efforts, we may not be successful in achieving compliance if our employees or contractual partners fail to comply with our published policies, certifications and documentation. The publication of our privacy policy and other statements that provide promises and assurances about data privacy and security can subject us to potential government or legal action if they are found to be deceptive, unfair or misrepresentative of our actual practices. Any failure, real or perceived, by us to comply with our posted privacy policies or with any legal or regulatory requirements, standards, certifications or orders or other privacy or consumer protection-related laws and regulations applicable to us could cause our customers to reduce their use of our products and services and could materially and adversely affect our business, financial condition and results of operations. In many jurisdictions, enforcement actions and consequences for non-compliance can be significant and are rising. In addition, from time to time, concerns may be expressed about whether our products, services or processes compromise the privacy of customers and others. Concerns about our practices with regard to the collection, use, retention, security, disclosure, transfer and other processing of personal information or other privacy-related matters, even if unfounded, could damage our reputation and materially and adversely affect our business, financial condition and results of operations.

Many statutory requirements, both in the United States and abroad, include obligations for companies to notify individuals of security breaches involving certain personal information, which could result from breaches experienced by us or our third-party service providers. For example, laws in all 50 U.S. states and the District of Columbia require businesses to provide notice to consumers whose personal information has been disclosed as a result of a data breach. These laws are not consistent, and compliance in the event of a widespread data breach is difficult and may be costly. We also may be contractually required to notify customers or other counterparties of a security breach. Although we may have contractual protections with our third-party service providers, contractors and consultants, any actual or perceived security breach could harm our reputation and brand, expose us to potential

liability or require us to expend significant resources on data security and in responding to any such actual or perceived breach or security incident. Any contractual protections we may have from our third-party service providers, contractors or consultants may not be sufficient to adequately protect us from any such liabilities and losses, and we may be unable to enforce any such contractual protections.

In addition to the possibility of fines, lawsuits, regulatory investigations, public censure, other claims and penalties, and significant costs for remediation and damage to our reputation, we could be materially and adversely affected if legislation or regulations are expanded in a manner that requires changes in our data processing practices and policies or if governing jurisdictions interpret or implement their legislation or regulations in ways that negatively impact our business. Complying with these various laws could cause us to incur substantial costs or require us to change our business practices and compliance procedures in a manner adverse to our business. Any inability to adequately address data privacy or security-related concerns, even if unfounded, or to comply with applicable laws, regulations, standards and other obligations relating to data privacy and security, could result in additional cost and liability to us, harm our reputation and brand, damage our relationships with contract partners and the physician and patient community and have a material and adverse impact on our business.

Our internal computer systems, or those used by our third-party research institution collaborators, CROs or other contractors or consultants, may fail or suffer security breaches.

Despite the implementation of security measures, our internal computer systems and those of our CROs and other contractors, vendors, and consultants may be vulnerable to damage from cybersecurity risks, including attempts to gain unauthorized access to and to harm sensitive or confidential information and networks, insider threats, and ransomware. These vulnerabilities may be heightened as a result of flexible work arrangements, including hybrid or remote work policies implemented by us and our third-party contractors, that were first adopted in response to the COVID-19 pandemic and have continued by many businesses in an effort to attract and retain talent.

We have from time to time experienced, and may continue to experience in the future, cyber-attacks on our information technology systems despite our best efforts to prevent them. Although such incidents have been immaterial to our business to date, investigations into and remedial efforts in connection with any security incidents, even those with immaterial impact, can be costly and time-consuming, and any future incidents could be material, or cause significant disruption, to our business. For example, the loss of clinical trial data from completed, ongoing or future clinical trials could result in delays in our regulatory approval efforts and significantly increase our costs to recover or reproduce the data. Likewise, we rely on third parties for research and development, the manufacture and supply of drug product and drug substance and to conduct clinical trials. We depend on these third parties to implement adequate controls and safeguards to protect against and report cybersecurity incidents. If they fail to do so, we may suffer financial and other harm, including to our information, operations, performance, and reputation. To the extent that any disruption or security breach were to result in a loss of, or damage to, our data or systems, or inappropriate disclosure of confidential or proprietary information, we could incur liability and the further development and commercialization of our product candidates could be delayed.

Cybersecurity threats, both on premises and in the cloud, are evolving and include, but are not limited to: malicious software, destructive malware, ransomware, attempts to gain unauthorized access to systems or data, disruption to operations, critical systems or denial of service attacks; unauthorized release of confidential, personal or otherwise protected information; corruption of data, networks or systems; harm to individuals; and loss of assets. In addition, we could be impacted by cybersecurity threats or other disruptions or vulnerabilities found in products or services we use that are provided to us by third-parties. The techniques used by criminal elements to attack computer systems are sophisticated, change frequently and may originate from less regulated and remote areas of the world. As a result, we may not be able to address these techniques proactively or implement adequate preventative measures. These events, if not prevented or effectively mitigated, could damage our reputation, require remedial actions and lead to loss of business, regulatory actions, potential liability and other financial losses.

Certain data breaches must also be reported to affected individuals and various government and/or regulatory agencies, and in some cases to the media, under provisions of HIPAA, as amended by HITECH, other U.S. federal and state law, and requirements of non-U.S. jurisdictions, including the European Union Data Protection Directive, and financial penalties may also apply.

Our insurance policies may not be adequate to compensate us for the potential losses arising from breaches, failures or disruptions of our infrastructure, catastrophic events and disasters or otherwise. In addition, such insurance may not be available to us in the future on economically reasonable terms, or at all. Further, our insurance may not cover all claims made against us and defending a suit, regardless of its merit, could be costly and divert management’s attention.

Inadequate funding for the FDA, the SEC and other government agencies, including from government shut downs, or other disruptions to these agencies’ operations, could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing normal business functions on which the operation of our business may rely, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, ability to hire and retain key personnel and accept the payment of user fees, and statutory, regulatory and policy changes. Average review times at the agency have fluctuated in recent years as a result of these factors. Disruptions at the FDA and other agencies may also slow the time necessary for new product candidates to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. In addition, government funding of the SEC and other government agencies on which our operations may rely, including those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable.

Disruptions at the FDA and other agencies may also slow the time necessary for new product candidates to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

Risks Related to the Ownership of Our Common Stock

Our stock price is subject to fluctuation based on a variety of factors.

The market price of shares of our common stock could be subject to wide fluctuations as a result of many risks listed in this section, and other risks beyond our control, including:

These and other market and industry factors, including the effects of any future public health crises or other public health concerns, wars or armed conflicts, including the ongoing wars between Russia and Ukraine and between Israel and Hamas, the upcoming presidential election in the U.S. or similar events, and global economic conditions, may cause the market price and demand for our common stock to fluctuate substantially regardless of our actual operating performance, which may limit or prevent investors from readily selling their shares of common stock and may otherwise negatively affect the liquidity of our common stock.

Changes in our stock price may also trigger financial obligations under our licensing arrangements. For example, pursuant to the terms of the Amended MSKCC License, MSKCC is eligible to receive from us certain milestone payments totaling up to $75.0 million based on the price of our common stock, where the amount of such payments owed to MSKCC is contingent upon certain increases in the price of our common stock following the date of achievement of a specified clinical milestone. In July 2021, we achieved the specified clinical milestone for a licensed product under the Amended MSKCC License and our ten-trading day trailing average common stock price exceeded the first, pre-specified threshold. Accordingly, MSKCC received the first milestone payment of $20.0 million in November 2021; however, uncertainty of the price of our common stock results in an inability to ascertain the precise timing of any remaining future milestone payments in advance.

Additionally, a decrease in our stock price may cause our common stock to no longer satisfy the continued listing standards of Nasdaq. If we are not able to maintain the requirements for listing on Nasdaq, our common stock could be delisted, which could have a materially adverse effect on our ability to raise additional funds as well as the price and liquidity of our common stock.

Our principal stockholders and management own a significant percentage of our stock and may be able to exercise significant control over our company.

As of February 20, 2024, our executive officers, directors and entities affiliated with our five percent stockholders beneficially own, in the aggregate, shares representing approximately 54.8% of our outstanding voting stock. If, in accordance with the CoD (as such term is defined in Note 9 of the notes to the consolidated financial statements herewith) relating to the Class A Convertible Preferred Stock, Redmile (as such term is defined in Note 9 of the notes to the consolidated financial statements herewith) elects to remove certain limitations on the percentage of the our outstanding common stock that it may own such that the 2,761,108 shares of Class A Convertible Preferred Stock currently held by Redmile become fully convertible at Redmile’s option into 13,805,540 shares of common stock, the beneficial ownership of our executive officers, directors and entities affiliated with our five percent stockholders would increase to 59.4%. Although we are not aware of any voting arrangements in place among these stockholders, if these stockholders were to choose to act together, as a result of their stock ownership, they would be able to influence our management and affairs and control all matters submitted to our stockholders for approval, including the election of directors and approval of any merger, consolidation or sale of all or substantially all of our assets. This concentration of ownership may have the effect of delaying or preventing a change in control of our company that our other stockholders may believe are in their best interests, or adversely affecting the liquidity, volatility, and market price of our common stock. For example, if any of our directors, executive officers or other entities affiliated with our five percent stockholders elect to sell, transfer or otherwise dispose of a significant amount of shares of our common stock, this could result in a decrease in our stock price. Furthermore, any transferees or successors of all or a significant portion of our existing stockholders’ ownership in us will be able to exert a similar amount of control over us through their ownership position.

We may sell additional equity or debt securities or enter into other arrangements to fund our operations, which may result in dilution to our stockholders and impose restrictions or limitations on our business.

We expect that significant additional capital will be needed in the future to continue our planned operations, and we may seek additional funding through a combination of equity offerings, debt financings, state or government grants, strategic alliances, licensing and collaboration arrangements, or other third-party business arrangements. These financing activities may have an adverse effect on our stockholders’ rights, the market price of our common stock and on our operations and may require us to relinquish rights to some of our technologies, intellectual property or product candidates, issue additional equity or debt securities, or otherwise agree to terms unfavorable to us. Further, in November 2023, we filed a registration statement on Form S-3 pursuant to which we may issue and sell up to $300.0 million in common stock, preferred stock, debt securities, warrants and/or units, in one or more series or classes, including up to $100.0 million in shares of common stock that may be issued in sales deemed to be an “at the market offering” as defined by the Securities Act of 1933, as amended (the Securities Act). Any sale or issuance of securities pursuant to a registration statement or otherwise may result in dilution to our stockholders and may cause the market price of our stock to decline, and new investors could gain rights superior to our existing stockholders. In addition, any debt financings that we may enter into in the future may subject us to unfavorable repayment terms, including increased interest rates, impose restrictive covenants or otherwise adversely affect the holdings or the rights of our stockholders, and any additional equity financings will be dilutive to our stockholders. Furthermore, additional equity or debt financing might not be available to us on reasonable terms, if at all.

A significant portion of our total outstanding shares may be sold into the market in the near future, which could cause the market price of our common stock to drop significantly.

Sales of a substantial number of shares of our common stock in the public market could occur at any time. A significant portion of our outstanding shares of common stock are held by a small number of stockholders, including our directors, officers and significant stockholders. Sales by our stockholders of a substantial number of shares, or the expectation that such sales may occur, could significantly reduce the market price of our common stock.

For example, we registered all of the 5,250,000 shares of common stock issued by us in our August 2016 private placement transaction for resale on a Form S-3, which was declared effective by the SEC in September 2016. We also registered all of the 6,766,915 shares of common stock issued by us and all 14,097,745 shares of common stock issuable upon the conversion of an aggregate of 2,819,549 shares of Class A Convertible Preferred Stock issued by us in our November 2016 private placement transaction for resale on a Form S-3, which was declared effective by the SEC in January 2017. Additionally, we have registered the shares of common stock issued to Johnson & Johnson Innovation – JJDC, Inc. under the stock purchase agreement entered into in June 2020 in connection with the Janssen Agreement pursuant to a registration statement on Form S-3. Moreover, we registered all of the 5,380,117 shares of common stock issued by us and all of the 257,310 prefunded warrants to purchase common stock in our public offering in January 2021.

We have also registered or intend to register all shares of our common stock subject to options, restricted stock units or other equity awards issued or reserved for future issuance under our equity incentive plans. As a result, these shares will be available for sale in the public market subject to vesting arrangements and exercise of options, and restrictions under applicable securities laws. In addition, certain of our executive officers, employees and affiliates have established and may in the future establish programmed selling plans under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, for the purpose of effecting sales of our common stock. If any of these events cause a large number of our shares to be sold in the public market, the sales could reduce the trading price of our common stock and impede our ability to raise future capital.

Provisions of Delaware law or our charter documents could delay or prevent an acquisition of our company, and could make it more difficult for you to change management.

Provisions of Delaware law, our amended and restated certificate of incorporation, and our amended and restated bylaws may discourage, delay or prevent a merger, acquisition or other change in control that stockholders may consider favorable, including transactions in which stockholders might otherwise receive a premium for their shares. These provisions may also prevent or delay attempts by stockholders to replace or remove our current management or members of our board of directors. These provisions include:

In addition, because we are incorporated in Delaware, we are governed by the provisions of Section 203 of the Delaware General Corporation Law, which limits the ability of stockholders owning in excess of 15% of our outstanding voting stock to merge or combine with us. Any provision of our amended and restated certificate of incorporation or amended and restated bylaws or Delaware law that has the effect of delaying or discouraging a potential acquisition proposal or tender offer could limit the opportunity for our stockholders to achieve liquidity for their shares of our common stock, even if the acquisition proposal or tender offer is at a premium over the then-current market price for our common stock, and could also affect the price that some investors are willing to pay for our common stock.

Our amended and restated bylaws designate the Court of Chancery of the State of Delaware and the U.S. federal district courts as the exclusive forum for certain litigation that may be initiated by our stockholders, which could limit our stockholders’ ability to litigate disputes with us in a different judicial forum.

Pursuant to our amended and restated bylaws, unless we consent in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware will be the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf; (ii) any action asserting a claim of breach of a fiduciary duty or other wrongdoing by any of our directors, officers, or employees to us or our stockholders; (iii) any action asserting a claim against us arising pursuant to any provision of the General Corporation Law of the State of Delaware, our

amended and restated certificate of incorporation or our amended and restated bylaws; or (iv) any action asserting a claim governed by the internal affairs doctrine. This exclusive forum provision will not apply to any causes of action arising under the Securities Act. Unless we consent in writing to the selection of an alternate forum, the U.S. federal district courts shall be the sole and exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act. The forum selection clause in our amended and restated bylaws may limit our stockholders’ ability to litigate disputes with us in a different judicial forum.

Our ability to use our net operating loss carryforwards and certain other tax benefits may be limited and, as a result, our future tax liability may increase.

As of December 31, 2023, we had federal and California net operating loss carryforwards of $526.4 million and $522.1 million, respectively, some of which begin to expire in various amounts in 2027 and 2028, respectively. As of December 31, 2023, we also had federal and California research and development tax credit carryforwards of $40.3 million and $34.7 million, respectively. The federal research and development tax credit carryforwards will begin to expire in 2035 unless previously utilized, while the California carryforwards will carry forward indefinitely. These net operating loss and tax credit carryforwards could expire unused and be unavailable to offset future income tax liabilities. In addition, in general, under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended, a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its pre-change net operating losses (NOLs) or tax credits, or NOLs or credits, to offset future taxable income or taxes. Generally, a change of more than 50 percentage points in the ownership of a corporation’s stock, by value, over a three-year period constitutes an ownership change for U.S. federal income tax purposes. We have determined that we triggered an ownership change limitation in November 2009 and again in May 2015. We have determined that we do not believe there were any ownership changes from May 2015 through December 2023. We have not analyzed periods subsequent to December 2023. We may experience additional ownership changes as a result of shifts in our stock ownership in the future. Limits on our ability to use our pre-change NOLs or credits to offset U.S. federal taxable income could potentially result in increased future tax liability to us if we earn net taxable income in the future. The amount of NOLs generated in taxable periods beginning after December 31, 2023, that we are permitted to deduct in any taxable year is limited to 80% of our taxable income in such year, where taxable income is determined without regard to the NOL deduction itself. U.S. federal and certain state NOLs generated in taxable years beginning after December 31, 2017 are not subject to expiration.

General Risk Factors

We are and could be further subject to securities class action litigation and other types of stockholder litigation.

The stock market in general, and the Nasdaq Global Market and biotechnology companies in particular, have experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of these companies. Securities class action litigation has often been instituted against companies following periods of volatility in the market price of a company’s securities. For example, in January 2023, a purported stockholder filed a lawsuit against us and certain of our officers captioned Hadian v. Fate Therapeutics, Inc. et al. in the U.S. District Court for the Southern District of California and in June 2023, a derivative action was filed in the same court (see "Item 3. Legal Proceedings" for a more detailed description of this matter). We could also be subject to other types of litigation, which may involve claims of breach of fiduciary duties by our directors or officers for misuse/mismanagement of company assets/resources or conflicts of interest. Any such litigation, if instituted, could result in substantial costs and a diversion of management’s attention and resources, which would harm our business, operating results, or financial condition. Additionally, the dramatic increase in the cost of directors’ and officers’ liability insurance may cause us to opt for lower overall policy limits or to forgo insurance that we may otherwise rely on to cover significant defense costs, settlements, and damages awarded to plaintiffs.

Our business operations may subject us to disputes, claims and lawsuits, which may be costly and time-consuming and could materially and adversely impact our financial position and results of operations.

From time to time, we may become involved in disputes, claims and lawsuits relating to our business operations. For example, we have in the past and we may, from time to time, face or initiate claims related to intellectual property matters, employment matters, or commercial disputes. Any dispute, claim or lawsuit may divert management’s attention away from our business, we may incur significant expenses in addressing or defending any dispute, claim or lawsuit, and we may be required to pay damage awards or settlements or become subject to equitable remedies that could adversely affect our operations and financial results. Litigation related to these disputes may be costly and time-consuming and could materially and adversely impact our financial position and results of operations if resolved against us. In addition, the uncertainty associated with litigation could lead to increased volatility in our stock price.

Unfavorable global economic conditions could adversely affect our business, financial condition or results of operations.

Our ability to invest in and expand our business and meet our financial obligations, to attract and retain third-party contractors and collaboration partners and to raise additional capital depends on our operating and financial performance, which, in turn, is subject to numerous factors, including the prevailing economic and political conditions and financial, business, regulatory and other factors beyond our control, such as the rate of unemployment, rate of inflation, the number of uninsured persons in the United States, political influences and inflationary pressures, and fluctuations in costs, particularly due to changes in labor costs and material costs. For example, an overall decrease in or loss of insurance coverage among individuals in the United States due to high levels of unemployment, underemployment or the repeal of certain provisions of the ACA may decrease the demand for healthcare services and pharmaceuticals. If fewer patients are seeking medical care because they do not have insurance coverage or are unable to obtain medical care for their conditions due to resource constraints on the healthcare system, we may experience difficulties in any eventual commercialization of our product candidates and our business, results of operations, financial condition and cash flows could be adversely affected. In addition, if we are unable to manage cost fluctuations and inflationary pressures, including prices of materials, costs of labor, it may adversely impact our operating performance, expenses and results.

In addition, our results of operations could be adversely affected by general conditions in the global economy and in the global financial markets upon which pharmaceutical and biopharmaceutical companies such as us are dependent for sources of capital. In the past, global financial crises have caused extreme volatility and disruptions in the capital and credit markets. A severe or prolonged economic downturn, wars or armed conflicts, including the ongoing wars between Russia and Ukraine and between Israel and Hamas, interest rate fluctuations, rising inflations or recession, could result in a variety of risks to our business, including a reduced ability to raise additional capital when needed on acceptable terms, if at all, and weakened demand for our product candidates. A weak or declining economy, and rising inflation could also strain our suppliers, possibly resulting in supply disruption. Additionally, the upcoming 2024 U.S. Presidential election could cause additional legal, political and economic uncertainty. Any of the foregoing could harm our business and we cannot anticipate all of the ways in which ongoing wars and conflicts, current economic climate and financial market conditions could adversely impact our business.

Volatility in capital markets and lower market prices for our securities may affect our ability to access new capital through sales of shares of our common stock or issuance of indebtedness, which may harm our liquidity, limit our ability to grow our business, pursue acquisitions or improve our operating infrastructure and restrict our ability to compete in our markets.

Our operations consume substantial amounts of cash, and we intend to continue to make significant investments to support our business growth, respond to business challenges or opportunities, develop new product candidates, retain or expand our current levels of personnel, improve our existing products, enhance our operating infrastructure, and potentially acquire complementary businesses and technologies. Our future capital requirements may be significantly different from our current estimates and will depend on many factors, including the need to:

Accordingly, we may need to pursue equity or debt financings to meet our capital needs. With uncertainty in the capital markets and other factors, such financing may not be available on terms favorable to us or at all. If we raise additional funds through further issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences, and privileges superior to those of holders of our common stock. Any debt financing secured by us in the future could involve additional restrictive covenants relating to our capital-raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. If we are unable to obtain adequate financing or financing on terms satisfactory to us, we could face significant limitations on our ability to invest in our operations and otherwise suffer harm to our business.

Recent increases in interest rates could affect our ability to obtain working capital through borrowings such as bank credit lines and public or private sales of debt securities, which may result in lower liquidity, reduced working capital and other adverse impacts on our business.

To meet our liquidity needs, we have previously relied, in part, on borrowed funds, and may do so again in the future. Continued increases in interest rates will increase the cost of new indebtedness and could materially and adversely affect our results of operations, financial condition, liquidity and cash flows.

Increasing scrutiny and changing expectations from governments and third-parties relating to environmental, social and governance (ESG) policies and practices may cause us to incur additional costs or expose us to additional risks.

In recent years, there has been increasing public focus and scrutiny from certain investors, employees and other stakeholders concerning corporate responsibility, specifically related to ESG factors. Third-party providers of ESG ratings and reports on companies have increased in number, resulting in varied and, in some cases, inconsistent standards and frameworks. Topics taken into account in such assessments include, among others, our efforts and impacts with respect to climate change and the role of our board of directors in supervising various sustainability issues.

Some investors may use third-party ESG ratings and reports to guide their investment strategies and, in some cases, may choose not to invest in us if they believe our ESG practices are inadequate. At the same time, anti-ESG sentiment has gained some momentum across the United States, with several states having enacted or proposed “anti-ESG” policies or legislation, which may conflict with other laws or regulations. The criteria by which companies’ ESG practices are assessed are evolving, which could result in greater expectations of us and cause us to undertake costly initiatives to satisfy such new criteria. Alternatively, if we elect not to or are unable to satisfy new criteria or do not meet the criteria of a specific third-party provider, some investors may conclude that our policies with respect to ESG are inadequate and choose not to invest in us.

If our ESG practices do not meet evolving investor, government agency or other stakeholder expectations and standards, then our reputation, our ability to attract or retain employees and the market price of our securities could be negatively impacted. New governmental regulations could result in new directives and new or more stringent forms of ESG oversight and disclosures which may lead to increased expenditures for sustainability initiatives, which in turn could have a material adverse effect on our business, financial condition, cash flows and results of operations and could cause the market value of our common stock to decline.

Adverse developments affecting the financial services industry, such as actual events or concerns involving liquidity, defaults, or non-performance by financial institutions or transactional counterparties, could adversely affect our current and projected business operations and its financial condition and results of operations.

Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, Silicon Valley Bank (SVB) was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation (FDIC) as receiver. Similarly, on March 12, 2023, Signature Bank and Silvergate Capital Corp. were each swept into receivership. In these cases borrowers under credit agreements, letters of credit and certain other financial instruments with SVB, Signature Bank or any other financial institution that is placed into receivership by the FDIC may be unable to access undrawn amounts thereunder. We currently use deposit accounts to fund our operations and other financial instruments such as cash-collateralized letters of credit associated with our facilities leases. Our excess cash is invested according to a restrictive investment policy within custodial accounts at various financial institutions. If any of the financial institutions that hold our deposit accounts were to be placed into receivership, we may be unable to access the funds in those accounts, which could result in liquidity constraints or failures. In addition, if any of our collaboration partners, suppliers or other parties with whom we conduct business are unable to access funds pursuant to such instruments or lending arrangements with such a financial institution, such parties’ ability to pay their obligations to us or to enter into new commercial arrangements requiring additional payments to us could be adversely affected. In this regard, counterparties to SVB credit agreements and arrangements, and third parties such as beneficiaries of letters of credit (among others), may experience direct impacts from the closure of SVB, or the sale of its assets, and uncertainty remains over liquidity concerns in the broader financial services industry. Similar impacts have occurred in the past, such as during the 2008-2010 financial crisis.

Inflation and rapid increases in interest rates have led to a decline in the trading value of previously issued government securities. Although the U.S. Department of Treasury, FDIC and Federal Reserve Board have announced a program to provide up to $25 billion of loans to financial institutions secured by certain of such government securities held by financial institutions to mitigate the risk of potential losses on the sale of such instruments, widespread demands for customer withdrawals or other liquidity needs of financial institutions for immediately liquidity may exceed the capacity of such program. Additionally, there is no guarantee that the U.S. Department of Treasury, FDIC and Federal Reserve Board will provide access to uninsured funds in the future in the event of the closure of other banks or financial institutions, or that they would do so in a timely fashion.

Although we assess our banking and other business relationships as we believe necessary or appropriate, our access to funding sources and other credit arrangements in amounts adequate to finance or capitalize our current and projected future business operations could be significantly impaired by factors that affect us, the financial institutions with which we have credit agreements or arrangements directly, or the financial services industry or economy in general. These factors could include, among others, events such as liquidity constraints or failures, the ability to perform obligations under various types of financial, credit or liquidity agreements or arrangements, disruptions or instability in the financial services industry or financial markets or concerns or negative expectations about the prospects for companies in the financial services industry. These factors could involve financial institutions

with which we have financial or business relationships but could also include factors involving financial markets or the financial services industry generally.

The results of events or concerns that involve one or more of these factors could include a variety of material and adverse impacts on our current and projected business operations and our financial condition and results of operations. These could include, but may not be limited to, the following:

In addition, investor concerns regarding the U.S. or international financial systems could result in less favorable commercial financing terms, including higher interest rates or costs and tighter financial and operating covenants, or systemic limitations on access to credit and liquidity sources, thereby making it more difficult for us to acquire financing on acceptable terms or at all. Any decline in available funding or access to our cash and liquidity resources could, among other risks, adversely impact our ability to meet our operating expenses, financial obligations or fulfill our other obligations, result in breaches of our financial and/or contractual obligations or result in violations of federal or state wage and hour laws.

Any of these impacts, or any other impacts resulting from the factors described above or other related or similar factors not described above, could have material adverse impacts on our liquidity and our current and/or projected business operations and financial condition and results of operations.

In addition, any further deterioration in the macroeconomic economy or financial services industry could lead to losses or defaults by our collaboration partners, suppliers or other parties with whom we do business, which in turn, could have a material adverse effect on our current and/or projected business operations and results of operations and financial condition. Any bankruptcy or insolvency of a collaboration partner, supplier or other party with whom we do business, or the failure of any such party to make payments when due, or any breach or default by any such party, or the loss of any significant commercial relationships, could result in material losses to us and may have a material adverse impact on our business.

Geopolitical risks associated with ongoing wars and conflicts, including the ongoing wars between Russia and Ukraine and between Israel and Hamas, could have an adverse impact on our business, financial condition and results of operations, including our clinical trials.

There are ongoing conflicts, including the wars between Russia and Ukraine and between Israel and Hamas, and although the conflicts have had little direct impact on our business to date, the uncertainty and ripple effects created by these conflicts may have unknown indirect impacts. For instance, the ongoing conflicts have resulted in significant volatility in certain equity, debt and currency markets, material increases in certain commodity prices, and economic uncertainty. It is not possible to predict the broader or longer-term consequences of these conflicts, although a prolonged conflict may result in adverse effects on microeconomic conditions including inflation; disruptions to our global technology infrastructure, including through cyberattack, ransom attack, or cybersecurity-intrusion; adverse changes in international trade policies and relations; disruptions in global supply chains; our exposure to foreign currency fluctuations; and constraints, volatility, or disruption in the capital markets, any of which could negatively impact our business, financial performance and financial condition. Sanctions imposed by the United States, Canada, EU, and other countries in response to the ongoing conflicts and the potential response to such sanctions may also have an adverse impact our business, including our clinical trials, the financial markets and the global economy.

We continue to monitor any adverse impact that the outbreak of war and the subsequent institution of sanctions by the United States and other countries may have on the global economy in general, on our business and operations and on the businesses and operations of our suppliers and third parties with whom we conduct business.

We or the third parties upon whom we depend may be adversely affected by earthquakes, fires, or other natural disasters, including public health crises, and our business continuity and disaster recovery plans may not adequately protect us from a serious disaster.

Earthquakes, fires, or other natural disasters (including due to the effects of climate change or any public health crises) could severely disrupt our operations, and have a material adverse effect on our business, results of operations, financial condition and prospects. If a natural disaster, power outage or other event occurred that prevented us from using all or a significant portion of our headquarters, that damaged critical infrastructure, such as our manufacturing facilities or those of our CMOs, or that otherwise disrupted operations, it may be difficult or, in certain cases, impossible for us to continue our business for a substantial period of time. Further, any measures taken by governmental authorities or businesses in response to any public health crisis, such as quarantines, stay-at-home orders or travel restrictions, could adversely affect our business, operations, financial condition, prospects or results of operations by restricting our ability to conduct our clinical trials and research and development activities, and limiting our and our third-party manufacturers’ ability to manufacture product and forcing temporary closure of our facilities and facilities that we rely

upon. The disaster recovery and business continuity plans we have in place currently are limited and may not prove adequate for protecting and continuing our business in the event that our business is disrupted as a result of a public health crisis or other serious disaster or similar event. We may incur substantial expenses as a result of the limited nature of our disaster recovery and business continuity plans, which, when taken together with our lack of earthquake insurance, could have a material adverse effect on our business.

If we fail to maintain an effective system of disclosure controls and procedures and internal controls, our ability to produce accurate financial statements or comply with applicable regulations could be impaired.

As a public company, we are required to comply with the Sarbanes-Oxley Act of 2002, as amended (the Sarbanes-Oxley Act), and the related rules and regulations of the SEC, expanded disclosure requirements, accelerated reporting requirements and more complex accounting rules. Company responsibilities required by the Sarbanes-Oxley Act include establishing and maintaining corporate oversight and adequate internal control over financial reporting and disclosure controls and procedures. Effective internal controls are necessary for us to produce reliable financial reports and are important to help prevent financial fraud.

We cannot assure that we will not have material weaknesses or significant deficiencies in our internal control over financial reporting. If we are unable to successfully remediate any material weakness or significant deficiency in our internal control over financial reporting, or identify any material weaknesses or significant deficiencies that may exist, the accuracy and timing of our financial reporting may be adversely affected, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, and our stock price may decline materially as a result.

If we fail to comply with environmental, health, and safety laws and regulations, including regulations governing the handling, storage or disposal of hazardous materials, we could become subject to fines or penalties or incur costs that could harm our business.

We are subject to numerous environmental, health, and safety laws and regulations, including those governing laboratory procedures and the handling, use, storage, treatment, and disposal of hazardous materials and wastes. Our operations involve the use of hazardous materials, including chemicals, biological materials and infectious agents. Our operations also may produce hazardous waste products. We generally contract with third parties for the disposal of these materials and wastes. We will not be able to eliminate the risk of contamination or injury from these materials. In the event of contamination or injury resulting from any use by us of hazardous materials, we could be held liable for any resulting damages, and any liability could exceed our resources. We also could incur significant costs associated with civil or criminal fines and penalties for failure to comply with such laws and regulations.

Although we maintain workers’ compensation insurance to cover us for costs and expenses we may incur due to injuries to our employees resulting from the use of hazardous materials, this insurance may not provide adequate coverage against potential liabilities. We do not maintain insurance for environmental liability or toxic tort claims that may be asserted against us in connection with our storage or disposal of biological or hazardous materials.

In addition, we may incur substantial costs in order to comply with current or future environmental, health, and safety laws and regulations. These current or future laws and regulations may impair our research, development, or production efforts. Our failure to comply with these laws and regulations also may result in substantial fines, penalties or other sanctions.

Changes in tax law may adversely affect us or our investors.

The rules dealing with U.S. federal, state and local income taxation are constantly under review by persons involved in the legislative process and by the Internal Revenue Service (IRS) and the U.S. Treasury Department. Changes to tax laws (which changes may have retroactive application) could adversely affect us or holders of our common stock. In recent years, many such changes have been made and changes are likely to continue to occur in the future. For example, the Tax Cuts and Jobs Act was enacted in 2017 and made significant changes to corporate taxation, including the reduction of the corporate tax rate from a top marginal rate of 35% to a flat rate of 21%, the limitation of the tax deduction for net interest expense to 30% of adjusted taxable income (except for certain small businesses), the limitation of the deduction for net operating losses to 80% of current year taxable income and the elimination of net operating loss carrybacks (though any such net operating losses may be carried forward indefinitely), and the modification or repeal of many business deductions and credits. In addition, under Section 174 of the Internal Revenue Code of 1986, as amended, in taxable years beginning after December 31, 2021, expenses that are incurred for research and development in the U.S. will be capitalized and amortized, which may have an adverse effect on our cash flow. It cannot be predicted whether, when, in what form, or with what effective dates, tax laws, regulations and rulings may be enacted, promulgated or issued, which could result in an increase in our or our stockholders’ tax liability or require changes in the manner in which we operate in order to minimize or mitigate any adverse effects of changes in tax law.

ITEM 1B. Unresolved Staff Comments

Not Applicable.

ITEM 1C. Cybersecurity

We have implemented and maintain a cybersecurity risk management program that includes processes for the identification, assessment, and mitigation of cybersecurity risks. We conduct annual cybersecurity training for all of our employees and periodically engage third-party consultants to conduct penetrating testing and vulnerability assessments. Additionally, we use automated tools designed to monitor, identify, and address cybersecurity risks. Further, we have a process to evaluate and review the cybersecurity practices of our key vendors prior to onboarding, including through a general security assessment and contractual requirements, as appropriate.

We face a number of cybersecurity risks in connection with our business. Although such risks have not materially affected us, including our business strategy, results of operations or financial condition, to date, we have, from time to time, experienced threats to and breaches of our data and systems, including malware and computer virus attacks. For more information about the cybersecurity risks we face, see the risk factor entitled “Our internal computer systems, or those used by our third-party research institution collaborators, CROs or other contractors or consultants, may fail or suffer security breaches” in Item 1A- Risk Factors.

Governance Related To Cybersecurity Risks

Our cybersecurity process is overseen by our Information Technology department, which is managed by our Head of IT. The Head of IT role is currently held by an individual who has approximately two decades of professional IT management experience. In addition, our Security Leadership Team (SLT), which is comprised of the Head of IT as well as leaders from our operations, finance, and legal departments, is responsible for documenting, reviewing, and assessing our cybersecurity processes, monitoring for cybersecurity incidents, and periodically reporting on cybersecurity risks and risk management to a committee of our executive team (Executive Committee). The Executive Committee, which is led by our Chief Financial Officer, undertakes reviews of our cybersecurity program and assesses any security incident updates from the SLT on a quarterly basis.

The Executive Committee meets with the Audit Committee of our Board of Directors on a quarterly basis to report on and discuss material updates to our cybersecurity program. The Audit Committee provides oversight of our cybersecurity program as part of its periodic review of enterprise risk management and provides regular reports to our Board of Directors regarding our cybersecurity processes, including updates on the status of ongoing cybersecurity projects, the results of cybersecurity risk assessments, and the emerging cybersecurity threat landscape. Additionally, the Board of Directors reviews the enterprise risk management program on at least an annual basis.

ITEM 2. Properties

Facilities

As of December 31, 2023, we occupied approximately 200,000 square feet of office, laboratory and Good Manufacturing Practice (GMP) manufacturing space in San Diego, California under a non-cancelable operating lease through May 2036. In addition, we have additional operating leases for office and laboratory space in San Diego, California. We believe that these facilities are adequate for our current needs.

ITEM 3. Legal Proceedings

We are currently pursuing claims in two lawsuits that we filed in 2022 against Shoreline Biosciences, Inc. (Shoreline) and certain of its founders and officers (collectively, the Shoreline litigations). The first suit, filed on May 13, 2022, is pending in San Diego Superior Court against Shoreline and four of its founders, Drs. Dan S. Kaufman (Kaufman), Kleanthis G. Xanthopoulos, Steven Holtzman, and William Sandborn. Our claims stem from Kaufman’s founding of and participation in Shoreline’s business, in breach of his exclusivity obligations to us as our scientific advisor pursuant to a Scientific Advisor Agreement between Kaufman and the Company. Our claims include actions for breach of contract, breach of implied covenant of good faith and fair dealing, fraud and deceit, tortious interference, restitution and unfair competition. Fact and expert discovery is ongoing, and we are seeking monetary damages. Trial is presently scheduled to begin on July 19, 2024.

In the second of the Shoreline litigations, also filed on May 13, 2022, we and Whitehead Institute for Biomedical Research (Whitehead) filed a lawsuit in the U.S. District Court for the Southern District of California against Shoreline and Kaufman seeking monetary damages for the defendants’ infringement of U.S. Patent Nos. 8,071,369, 8,932,856, 8,951,797, 8,940,536, 9,169,490, 10,457,917, and 10,017,744 (the Whitehead Patents). The Whitehead Patents, which we exclusively license from Whitehead, relate to key compositions and methods for reprogramming human somatic cells to a pluripotent state in the generation of iPSCs. On June 7,

2023, we and Whitehead filed a motion to dismiss our patent infringement claims against Kaufman in his personal capacity; that motion was granted on June 9, 2023. On July 14, 2023 each party filed motions for summary judgment. On August 30, 2023, the court granted Shoreline’s motion for summary judgment and denied our motion for partial summary judgment as moot. Judgment in favor of Shoreline was entered on August 31, 2023. On October 16, 2023, the district court denied Shoreline’s motion for an award of costs and attorney’s fees. On September 27, 2023, we and Whitehead filed a Notice of Appeal with the Court of Appeals for the Federal Circuit challenging the trial court’s claim construction and grant of summary judgment in favor of the defendants; the defendants cross-appealed challenging the district court’s earlier denial of a motion to dismiss and partial motion for summary judgment on other grounds. The Federal Circuit docketed the case on October 5, 2023. There can be no assurance that we will prevail on any such appeal. We filed our opening appeal brief on February 2, 2024.

On January 20, 2023, a purported stockholder of the Company filed a securities class action lawsuit against the Company and certain of its officers captioned Hadian v. Fate Therapeutics, Inc. et al. in the U.S. District Court for the Southern District of California (the Securities Action). On May 4, 2023, the court appointed a different purported stockholder of the Company to serve as lead plaintiff in the Securities Action. On July 24, 2023, the lead plaintiff filed an amended complaint. The amended complaint alleges that the Company violated the federal securities laws by making allegedly false and/or misleading statements and/or omissions in its public disclosures dating back to August 2020 relating to our collaboration agreement with Janssen Biotech, Inc. (the Janssen Agreement), potential product candidates subject to the Janssen Agreement, and the termination of the Janssen Agreement. On September 22, 2023, we filed a motion to dismiss the amended complaint in its entirety. Briefing on our motion to dismiss was completed on December 6, 2023. The court may, in its discretion, either hold oral argument on the motion to dismiss or issue a ruling on the motion based upon the parties’ briefing. We intend to continue to vigorously defend against this action.

On June 2, 2023, a derivative complaint, captioned Guarino v. Wolchko, et al., was filed by a purported stockholder of the Company in the U.S. District Court for the Southern District of California. The derivative lawsuit names members of our board of directors and certain officers as defendants. The Company is named as a nominal defendant. The plaintiff asserts derivative claims arising out of substantially the same alleged facts and circumstances as the Securities Action. The complaint asserts claims for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, waste of corporate assets, and violation of federal securities laws. On August 14, 2023, the court stayed the derivative lawsuit pending the court’s decision on our motion to dismiss in the Securities Action filed September 22, 2023. We intend to vigorously defend against this action.

From time to time, we may be subject to various other legal proceedings and claims that arise in the ordinary course of our business activities.

ITEM 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

You should read the following discussion and analysis of our financial condition and results of operations together with our consolidated financial statements and related notes included under Item 8 of this Annual Report on Form 10-K. The following discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those expressed or implied in any forward-looking statements as a result of various factors, including those set forth under the caption “Item 1A. Risk Factors.”

Overview

We are a clinical-stage biopharmaceutical company dedicated to bringing a first-in-class pipeline of programmed cellular immunotherapies to patients with cancer and autoimmune diseases. Our development of programmed cellular immunotherapies is based on a simple notion: we believe that better cell therapies start with better cells.

To create better cell therapies, we have pioneered a therapeutic approach that we generally refer to as cell programming: we create and engineer human induced pluripotent stem cells (iPSCs) to incorporate novel synthetic controls of cell function; we generate a clonal master iPSC line for use as a renewable source of cell manufacture; and we direct the fate of the clonal master iPSC line to produce our cell therapy product candidate. Analogous to master cell lines used to manufacture biopharmaceutical drug products such as monoclonal antibodies, we believe clonal master iPSC lines can be used to mass produce multiplexed-engineered cellular immunotherapies which are well-defined and uniform in composition, can be stored in inventory for off-the-shelf availability, can be combined and administered with other therapies, and can have broader patient reach.

Utilizing our proprietary iPSC product platform, we are advancing off-the-shelf, multiplexed-engineered natural killer (NK) and T-cell product candidates which are selectively designed to incorporate novel synthetic controls of cell function, and are intended to deliver multiple therapeutic mechanisms to patients for the treatment of cancer and autoimmune diseases. We have a deep pipeline of iPSC-derived, chimeric antigen receptor (CAR)-targeted NK and T-cell product candidates currently under development with multiple clinical trials ongoing. In addition, we have entered into research collaborations and license agreements with academic institutes to support the development of our iPSC product platform and our off-the-shelf product candidates, including, among others, the Regents of the University of Minnesota and Memorial Sloan Kettering Cancer Center (MSKCC).

We have also entered into collaborations with pharmaceutical companies to research, develop and commercialize off-the-shelf, multiplexed-engineered, iPSC-derived NK and T-cell product candidates for the treatment of cancer. In September 2018, we entered into a collaboration and option agreement (Ono Agreement) with Ono Pharmaceutical Co., Ltd. (Ono), under which we are currently researching and developing iPSC-derived CAR NK and CAR T-cell product candidates for the treatment of solid tumors. In April 2020, we entered into a collaboration and option agreement (Janssen Agreement) with Janssen Biotech, Inc. (Janssen), part of the Janssen Pharmaceutical Companies of Johnson & Johnson, for the research, development and commercialization of iPSC-derived CAR NK and CAR T-cell product candidates for the treatment of cancer. On January 3, 2023, we received notice of termination of the Janssen Agreement from Janssen, which took effect on April 3, 2023.

We were incorporated in Delaware in 2007 and are headquartered in San Diego, California. Since our inception in 2007, we have devoted substantially all of our resources to our cell programming approach and the research and development of our product candidates, the creation, licensing and protection of related intellectual property, and the provision of general and administrative support for these activities. To date, we have funded our operations primarily through the public and private sale of common stock, the private placement of preferred stock and convertible notes, commercial bank debt and revenues from collaboration activities and grants.

We have never been profitable and have incurred net losses in each year since inception. Substantially all of our net losses resulted from costs incurred in connection with our research and development programs and from general and administrative costs associated with our operations. We expect to continue to incur operating losses for at least the foreseeable future. Our net losses may fluctuate significantly from quarter to quarter and year to year. We expect our expenses will remain significant in connection with our ongoing and planned activities as we:

We do not expect to generate any meaningful revenues from product sales, royalties, or sales milestones unless and until we successfully complete development and obtain regulatory approval for one or more of our product candidates, which we expect will take a number of years. If we obtain regulatory approval for any of our product candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing and distribution. Accordingly, we will seek to fund our operations through public or private equity or debt financings, collaboration arrangements, or other sources. However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at all. Our failure to raise capital or enter into such other arrangements when needed would have a negative effect on our financial condition and ability to develop our product candidates.

Financial Operations Overview

Collaboration Revenue

To date, we have not generated any revenues from therapeutic product sales or royalties. Our revenues have been derived from collaboration agreements and government grants.

Agreement with Ono Pharmaceutical Co., Ltd.

On September 14, 2018, we entered into the Ono Agreement for the joint development and commercialization of two iPSC-derived CAR T-cell product candidates (Candidate 1 and Candidate 2). Pursuant to the terms of the Ono Agreement, we received an upfront, non-refundable and non-creditable payment of $10.0 million. Additionally, we are entitled to receive fees for the conduct of research and development under a joint development plan, which fees were estimated to be $20.0 million in aggregate.

In December 2020, we entered into a letter agreement with Ono pursuant to which Ono delivered proprietary antigen binding domains targeting an antigen expressed on certain solid tumors for incorporation into Candidate 2 and paid the Company a milestone fee of $10.0 million for further research and development of Candidate 2. In addition, Ono terminated all further research and development with respect to Candidate 1, and we retained all rights to research, develop and commercialize Candidate 1 throughout the world without any obligation to Ono.

In June 2022, we entered into the 2022 Ono Amendment. Pursuant to the 2022 Ono Amendment, the companies agreed to designate an additional antigen expressed on certain solid tumors for research and preclinical development, and Ono agreed to contribute proprietary antigen binding domains targeting such additional solid tumor antigen (Candidate 3). In addition, for both Candidate 2 and Candidate 3, the companies expanded the scope of the collaboration to include the research and development of iPSC-derived CAR NK cell product candidates (in addition to iPSC-derived CAR T-cell product candidates) targeting the designated solid tumor antigens. Similar to Candidate 2, we granted to Ono, during a specified period of time, a preclinical option to obtain an exclusive license under certain intellectual property rights, subject to payment of an option exercise fee to us by Ono, to develop and commercialize Candidate 3 in all territories of the world, where we retain rights to co-develop and co-commercialize Candidate 3 in the United States and Europe under a joint arrangement with Ono under which we are eligible to share at least 50% of the profits and losses. We maintained worldwide rights of manufacture for Candidate 3. The preclinical option expires upon the earlier of: (a) September 30, 2024, or (b) the achievement of the pre-defined preclinical milestone under the joint development plan for Candidate 3. Subject to payment of an extension fee by Ono, Ono may choose to defer its decision to exercise the preclinical option until no later than June 2026. Under the 2022 Ono Amendment, aggregate estimated research and development fees have been increased by approximately $9.3 million, for a total estimated $29.3 million in aggregate research and development fees over the course of the joint development plan.

In November 2022, Ono exercised its preclinical option to Candidate 2, and we exercised our preclinical option to co-develop and co-commercialize (CDCC Option) in the United States and Europe under a joint arrangement with Ono. As a result, we recognized an option exercise fee of $12.5 million from Ono during the year ended December 31, 2022. We received the option exercise fee payment during the year ended December 31, 2023.

On November 30, 2023, we entered into the 2023 Ono Amendment. Under the 2023 Ono Amendment, aggregate estimated research and development fees have been increased by approximately $1.4 million, for a total estimated $30.7 million in aggregate research and development fees over the course of the joint development plan.

We account for the Ono Agreement as a revenue contract under ASC 606. The initial transaction price as amended under the 2023 Ono Amendment was determined to be $40.7 million, consisting of the upfront, non-refundable and non-creditable payment of $10.0 million and the aggregate estimated research and development fees of $30.7 million. We identified our promised goods and services under the Ono Agreement to include our grant to Ono of a license to certain of our intellectual property subject to certain conditions, our conduct of research services, and our participation in a joint steering committee. We determined that the promised goods and services should be accounted for as one combined performance obligation. We recognize revenue for the combined performance obligation over time as the research services are performed.

During the years ended December 31, 2023 and 2022, we recognized $11.2 million and $16.6 million, respectively, of collaboration revenue under the Ono Agreement. As of December 31, 2023, aggregate deferred revenue related to the Ono Agreement, Ono Letter Agreement, and Ono Amendments was $0.7 million.

Agreement with Janssen Biotech, Inc.

On April 2, 2020, we entered into the Janssen Agreement as well as a Stock Purchase Agreement (the Stock Purchase Agreement) with Johnson & Johnson Innovation - JJDC, Inc. (JJDC). On January 3, 2023, we received notice of termination from Janssen of the Janssen Agreement. The termination took effect on April 3, 2023, and during the three months ending March 31, 2023, we performed wind down activities, including discontinuing development of all collaboration product candidates under the Janssen Agreement. We were reimbursed for all wind down activities associated with the termination of the Janssen Agreement during the second quarter of this year.

Under the terms of the Janssen Agreement and the Stock Purchase Agreement taken together, we received $100.0 million, of which $50.0 million was an upfront cash payment and $50.0 million was in the form of an equity investment by JJDC. We determined the common stock purchase by JJDC represented a premium of $9.93 per share, or $16.0 million in aggregate (the Equity Premium), and the remaining $34.0 million was recorded as issuance of common stock in shareholders’ equity.

Additionally, prior to termination of the Janssen Agreement, we received fees from Janssen for the conduct of all research, preclinical development and IND-enabling activities performed by us under the Janssen Agreement. In addition, Janssen had exercised a commercial option for two collaboration candidates: an iPSC-derived, CAR NK cell product candidate for the treatment of B-cell lymphoma, for which the U.S. Food and Drug Administration (FDA) allowed an Investigational New Drug (IND) application in December 2022; and an iPSC-derived, CAR NK cell product candidate for the treatment of multiple myeloma, for which the companies were preparing to submit an IND application to the FDA in early 2023.

Research and Development Expenses

Research and development expenses consist of costs associated with the research, preclinical development, process and scale-up development, manufacture and clinical development of our product candidates, the research and development of our cell programming technology including our iPSC product platform, and the performance of research and development activities under our collaboration agreements. These costs are expensed as incurred and include:

We plan to continue to significantly invest in our current level of research and development activities for the foreseeable future as we continue the clinical and preclinical development and manufacture of our product candidates, research and develop our iPSC product platform, and perform our obligations under collaboration agreements including under our agreements with Ono, University of Minnesota and MSKCC. Our current planned research and development activities over the next twelve months consist primarily of the following:

Due to the inherently unpredictable nature of preclinical and clinical development and manufacture, and given our novel therapeutic approach and the current stage of development of our product candidates, we cannot determine and are unable to estimate with certainty the timelines we will require and the costs we will incur for the development and manufacture of our product candidates. Clinical and preclinical development and manufacturing timelines and costs, and the potential of development and manufacturing success, can differ materially from expectations. In addition, we cannot forecast which product candidates may be subject to future collaborations, when such arrangements will be secured, if at all, and to what degree such arrangements would affect our development and manufacturing plans and capital requirements. We cannot predict the effects of the impact of global economic and market conditions, a continued and prolonged public health emergency such as the COVID-19 pandemic, and wars and other armed conflicts, such as the ongoing wars between Russia and Ukraine and between Israel and Hamas, on our business and operations, and our expenditures may be increased by delays or disruptions due to these or other factors, including as a result of actions we take in the near term to ensure business continuity and protect against possible supply chain shortages.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and employee-related costs, including stock-based compensation, for our employees in executive, operational, finance and human resource functions; professional fees for accounting, legal and tax services; costs for obtaining, prosecuting, maintaining, and enforcing our intellectual property; and other costs and fees, including director and officer insurance premiums, to support our operations as a public company. We anticipate that our general and administrative expenses will remain significant in the future as we maintain our focus on innovation, and research and development activities, maintain compliance with exchange listing and SEC requirements, protect and enforce our intellectual property, and continue to operate as a public company.

Other Income (Expense)

Other income (expense) consists of changes in the fair value of stock price appreciation milestones associated with the Amended and Restated Exclusive License Agreement dated May 15, 2018 (Amended MSKCC License) with MSKCC, interest income earned on cash and cash equivalents and interest income from investments (including the amortization of discounts and premiums).

California Institute for Regenerative Medicine Award

On April 5, 2018, we executed an award agreement with the California Institute for Regenerative Medicine (CIRM) pursuant to which CIRM awarded us $4.0 million to advance our FT516 product candidate into a first-in-human clinical trial (the Award). In November 2019, we submitted an IND application for FT516 in advanced solid tumors.

Pursuant to the terms of the Award, we, in our sole discretion, have the option to treat the Award either as a loan or as a grant. During the first quarter of 2023, we elected to treat the Award as a grant and derecognized the liability associated with the Award and recorded such amount in other income during the year ended December 31, 2023.

Employee Retention Credit

The Coronavirus Aid, Relief and Economic Security (CARES) Act provides an employee retention credit (ERC), which is a refundable tax credit against certain employment taxes of up to $5,000 per employee for eligible employers. The tax credit is equal to 50% of qualified wages paid to employees during a quarter, capped at $10,000 of qualified wages per employee through December 31, 2020. Additional relief provisions were passed by the United States government, which extend and slightly expand the qualified wage caps on these credits through December 31, 2021. Based on these additional provisions, the tax credit is now equal to 70% of qualified wages paid to employees during a quarter, and the limit on qualified wages per employee has been increased to $10,000 of qualified wages per quarter. In connection with the CARES Act, we adopted a policy to recognize an ERC when it is reasonably assumed we will comply with the conditions and the grant will be received and include in other income in the statement of operations. The Company received a cash payment and recorded $5.1 million and $0.5 million of other income during the years ended December 31, 2023 and 2022, respectively.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with United States generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses and the disclosure of contingent assets and liabilities in our financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to the fair value of the stock price appreciation milestones for the Amended MSKCC License, contracts containing leases, accrued expenses, stock-based compensation, and the estimated total costs expected to be incurred under our collaboration agreements. We base our estimates on historical experience, known trends and events, financial models, and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in the notes to our financial statements appearing elsewhere in this Annual Report on Form 10-K, we believe that the following critical accounting policies reflect the more significant procedures, estimates and assumptions used in the preparation of our consolidated financial statements.

Collaborative Arrangements

We analyze our collaboration arrangements to assess whether they are within the scope of ASC Topic 808, Collaborative Arrangements (ASC 808), to determine whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards that are dependent on the commercial success of such activities. To the extent the arrangement is within the scope of ASC 808, we assess whether aspects of the arrangement between us and our collaboration partner are within the scope of other accounting literature, including ASC Topic 606, Revenue from Contracts with Customers (ASC 606). If it is concluded that some or all aspects of the arrangement represent a transaction with a customer, we will account for those aspects of the arrangement within the scope of ASC 606.

ASC 808 provides guidance for the presentation and disclosure of transactions in collaborative arrangements, but it does not provide recognition or measurement guidance. Therefore, if we conclude a counterparty to a transaction is not a customer or otherwise not within the scope of ASC 606, we consider the guidance in other accounting literature as applicable or by analogy to account for such transaction. The classification of transactions under our arrangements is determined based on the nature and contractual terms of the arrangement along with the nature of the operations of the participants.

Revenue Recognition

We recognize revenue in a manner that depicts the transfer of control of a product or a service to a customer and reflects the amount of the consideration we are entitled to receive in exchange for such product or service. In doing so, we follow a five-step approach: (i) identify the contract with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations, and (v) recognize revenue when (or as) the customer obtains control of the product or service. We consider the terms of a contract and all relevant facts and circumstances when applying the revenue recognition standard. We apply the revenue recognition standard, including the use of any practical expedients, consistently to contracts with similar characteristics and in similar circumstances.

A performance obligation is defined as a promise to transfer a product or a service to a customer. If a promise to transfer a product or a service is not separately identifiable from other promises in the contract, such promises should be combined into a single performance obligation. We determined that the promised goods and services for our collaboration agreements should be accounted

for as one combined performance obligation. We recognize revenue for the combined performance obligation over time as the research services are performed.

The transaction price is the amount of consideration we are entitled to receive in exchange for the transfer of control of a product or a service to a customer. To determine the transaction price, we consider the existence of any significant financing component, the effects of any variable elements, noncash considerations and consideration payable to the customer. For our collaboration agreements, we calculate the transaction price as an estimate of the total research and development plan reimbursement.

We expense incremental costs of obtaining and fulfilling a contract as and when incurred if the expected amortization period of the asset that would be recognized is one year or less, or if the amount of the asset is immaterial. Otherwise, such costs are capitalized as contract assets if they are incremental to the contract and amortized to expense proportionate to revenue recognition of the underlying contract.

Stock Price Appreciation Milestones

We estimate the fair value of the stock price appreciation milestones under the Amended MSKCC License using a Monte Carlo simulation model, which relies on our current stock price at the end of each quarter as well as significant estimates and assumptions to determine the estimated liability associated with the contingent milestone payments. We account for the fair value of the stock price appreciation milestones in accordance with ASC 815, Derivatives and Hedging, with fair value marked to market. The assumptions used to calculate the fair value of the stock price appreciation milestones are subject to a significant amount of judgment including the assessment of achieving a specified clinical milestone, the expected volatility of our common stock, the risk-free interest rate and the estimated term, which is based in part on the last valid patent claim date. We achieved the specified clinical milestone in July 2021 and met the first milestone during fiscal 2021. Accordingly, we remitted a payment to MSKCC of $20.0 million in the year ended December 31, 2021. We remeasure the fair value of the remaining stock price appreciation milestones at each balance sheet date, with changes in fair value recorded in earnings as a non-operating income or expense.

Accrued Research and Development Expenses

As part of the process of preparing our financial statements, we are required to estimate our accrued expenses. This process involves reviewing open contracts and purchase orders, communicating with our personnel to identify services that have been performed on our behalf and estimating the level of service performed and the associated cost incurred for the service when we have not yet been invoiced or otherwise notified of the actual cost. The majority of our service providers invoice us monthly in arrears for services performed or when contractual milestones are met. We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known to us at that time. We periodically confirm the accuracy of our estimates with the service providers and make adjustments if necessary. Examples of accrued research and development expenses include amounts owed to clinical research organizations, to investigative sites in connection with clinical trials, to sponsored research organizations, to service providers in connection with preclinical development activities and to service providers related to product manufacturing, development and distribution of clinical supplies.

We base our accrued expenses related to clinical trials on our estimates of the services performed and efforts expended pursuant to our contractual arrangements, including those with clinical research organizations. The financial terms of these agreements are sometimes subject to negotiation, vary from contract to contract and may result in uneven payment flows. There may be instances in which payments made to our service providers will exceed the level of services performed and result in a prepayment of the clinical expense. Payments under some of these contracts depend on factors such as the successful enrollment of patients and the completion of clinical milestones. In accruing service fees, we estimate the time period over which services will be performed and the level of effort to be expended in each period. If the actual timing of the performance of services or the level of effort varies from our estimate, we adjust the accrual or prepaid accordingly.

Although we do not expect our estimates to be materially different from expenses actually incurred, if our estimates of the status and timing of services performed differs from the actual status and timing of services performed, we may report amounts that are too high or too low in any particular period. To date, there have been no material differences from our estimates to the amounts actually incurred.

Stock-Based Compensation

Stock-based compensation expense represents the grant date fair value of employee stock option and restricted stock unit grants recognized over the requisite service period of the awards (usually the vesting period) on a straight-line basis. Performance-based stock units/awards represent a right to receive a certain number of shares of common stock based on the achievement of corporate performance goals and continued employment during the vesting period. At each reporting period, and to the extent achievement of one or any of the performance conditions is probable, we reassess the probability of the achievement of such corporate performance goals and any increase or decrease in share-based compensation expense resulting from an adjustment in the estimated shares to be released is treated as a cumulative catch-up in the period of adjustment.

We estimate the fair value of stock option grants using the Black-Scholes option pricing model, with the exception of option grants with both performance-based milestones and market conditions, which are valued using a lattice-based model. These models require the use of highly subjective and complex assumptions which determine the fair value of stock-based awards, (a) the risk-free interest rate, (b) the expected volatility of our stock, (c) the expected term of the award and (d) the expected dividend yield. The expected volatility is based on the historical volatility of our common stock over the most recent period commensurate with the estimated expected term of our stock options which is derived from historical experience and anticipated future exercise behavior. The risk-free interest rates for periods within the expected life of the option are based on the yields of zero-coupon U.S. Treasury securities. See Note 9 of the notes to the consolidated financial statements for additional information.

The fair value of our restricted stock units, including performance-based restricted stock units, is based on the closing price of our common stock as reported on The NASDAQ Global Market on the date of grant.

Results of Operations

Comparison of Years Ended December 31, 2023 and 2022

The following table summarizes the results of our operations for the years ended December 31, 2023 and 2022:

Revenue. During the year ended December 31, 2023, we recognized revenue of $63.5 million under our collaboration agreements with Janssen and Ono. During the year ended December 31, 2022, we recognized revenue of $96.3 million under our collaboration agreements with Janssen and Ono. The decrease in revenue was attributable primarily to the termination of our collaboration with Janssen in April 2023. The following table summarizes the revenue recognized with respect to each collaboration partner for the years ended December 31, 2023 and 2022:

Research and development expenses. Research and development expenses were $172.6 million for the year ended December 31, 2023, compared to $320.5 million for the year ended December 31, 2022. The decrease in research and development expenses includes the impact of the termination of our collaboration with Janssen in April 2023 and was attributable primarily to the following:

General and administrative expenses. General and administrative expenses were $81.4 million for the year ended December 31, 2023, compared to $84.2 million for the year ended December 31, 2022. The decrease in general and administrative expenses was attributable primarily to the following:

Other income. Other income was $29.6 million and $26.7 million for the years ended December 31, 2023 and 2022, respectively. During the year ended December 31, 2023, we recorded $4.0 million in income attributable to the CIRM Award, $5.1 million in income attributable to the ERC, and $2.5 million in other income attributable to the change in fair value of the stock price appreciation milestone under the Amended MSKCC License. Other income for the year ended December 31, 2023 also consisted of $17.2 million interest income earned on cash and cash equivalents and interest income from investments (including the amortization of discounts and premiums). During the year ended December 31, 2022, we recorded $20.3 million in other income attributable to the fair value of the stock price appreciation milestones under the Amended MSKCC License. Other income for the year ended December 31, 2022 also consisted of interest income earned on cash and cash equivalents and interest income from investments (including the amortization of discounts and premiums).

Liquidity and Capital Resources

We have incurred losses and negative cash flows from operations since inception. As of December 31, 2023, we had an accumulated deficit of $1.2 billion and anticipate that we will continue to incur net losses for the foreseeable future.

The following table sets forth a summary of the net cash flow activity for each of the years ended December 31:

Operating Activities

Cash used in operating activities decreased from $248.2 million for the year ended December 31, 2022 to $132.3 million for the year ended December 31, 2023. The primary drivers of this change in cash used in operating activities was our decrease of $120.8 million in net loss primarily due to the termination of the Janssen agreement, restructuring activities and discontinuation of programs implemented in January 2023.

Investing Activities

During the years ended December 31, 2023 and 2022, investing activities provided cash of $112.7 million and $166.8 million, respectively. During the year ended December 31, 2023 we purchased $358.8 million of investments, which were partially offset by $477.6 million in maturities of investments. During the year ended December 31, 2022 we purchased $404.8 million of investments, which were partially offset by $607.1 million in maturities of investments. The remaining investing activities for the periods presented were primarily attributable to the purchase of property and equipment.

Financing Activities

Financing activities provided cash of $0.1 million for the year ended December 31, 2023, which consisted of $0.1 million received from the issuance of common stock from equity incentive plans pursuant to the exercise of employee stock options.

Financing activities provided cash of $9.2 million for the year ended December 31, 2022, which consisted of $9.2 million received from the issuance of common stock from equity incentive plans pursuant to the exercise of employee stock options.

From our inception through December 31, 2023 we have funded our consolidated operations primarily through the public and private sale of common stock, the private placement of preferred stock and convertible notes, commercial bank debt and revenues from collaboration activities and grants. As of December 31, 2023, we had aggregate cash and cash equivalents and investments of $316.2 million.

Registration Statements on Form S-3

In November 2023, the SEC declared effective a shelf registration statement on Form S-3 filed by us in November 2023 (File No. 333-275402). The shelf registration statement allows us to issue certain securities, including shares of our common stock, from time to time. The specific terms of any offering under the shelf registration statement would be established at the time of such offering. We are eligible to issue an aggregate of $300.0 million in securities under the shelf registration statement. Additionally, we entered into a sales agreement with Jefferies Group LLC (Jefferies) with respect to an at-the-market offering program, under which we may offer and sell, from time to time at our sole discretion, shares of our common stock having an aggregate offering price of up to $100.0 million (which is included in the $300.0 million registered under the shelf registration statement) through Jefferies as the sales agent. To date, we have not sold any securities pursuant to the sales agreement with Jefferies or the shelf registration statement.

Operating Capital Requirements

We anticipate that we will continue to incur losses for the foreseeable future, and we expect the losses to remain significant as we continue the research, manufacture and development of, and seek regulatory approvals for, our product candidates and conduct additional research, manufacturing and development activities pursuant to our collaboration agreement with Ono. Our product candidates have not yet achieved regulatory approval and we may not be successful in achieving commercialization of our product candidates.

We are also subject to all the risks and uncertainties incident in the research, manufacture and development of therapeutic products, and cell therapy product candidates in particular. For example, the FDA or other regulatory authorities may require us to generate additional data or conduct additional preclinical studies, manufacturing activities, or clinical trials, or may impose other requirements beyond those that we currently anticipate. Additionally, it is possible for a product candidate to show promising results in preclinical studies or in clinical trials, but fail to establish sufficient safety and efficacy data necessary to obtain regulatory approvals. As a result of these and other risks and uncertainties and the probability of success, the duration and the cost of our research, manufacturing and development activities required to advance a product candidate cannot be accurately estimated and are subject to considerable variation. We may encounter difficulties, complications, delays and other unknown factors and unforeseen expenses in the course of our research, manufacturing and development activities, any of which may significantly increase our capital requirements and could adversely affect our liquidity.

We will require additional capital for the research, manufacture and development of our product candidates and to perform our obligations under our collaboration agreements, and we may need to seek additional funds sooner than expected due to any changes in our business, operations, financial condition or prospects, including any impacts of inflation rates and global economic conditions, and wars or other armed conflicts. We expect to finance our capital requirements in the foreseeable future through the sale of public or private equity, debt securities, or through existing or future potential collaborations. However, additional capital may not be available to us on reasonable terms, if at all. If we are unable to raise additional capital in sufficient amounts or on terms acceptable to us, we may have to significantly delay, scale back or discontinue the research, manufacture or development of one or more of our product candidates. If we do raise additional funds through the issuance of additional equity or debt securities, it could result in dilution to our existing stockholders, increased fixed payment obligations and the existence of securities with rights that may be senior to those of our common stock. Additionally, if we incur indebtedness, we may become subject to financial or other covenants that could adversely restrict, impair or affect our ability to conduct our business, such as requiring us to relinquish rights to certain of our product candidates or technologies or limiting our ability to acquire, sell or license intellectual property rights or incur additional debt. Any of these events could significantly harm our business, operations, financial condition and prospects. In addition, the full impact of inflation rates, global political and economic instability, a continued and prolonged public health emergency such as the COVID-19 pandemic, and wars and other armed conflicts, on our business, operations, financial condition and prospects, and on the global economy, are currently unknown and difficult to predict, and these events could materially and adversely affect our ability to raise capital through equity or debt financings in the future.

Our forecast of the period of time through which our existing cash and cash equivalents and investments will be adequate to support our operations is a forward-looking statement and involves significant risks and uncertainties. We have based this forecast on assumptions that may prove to be wrong, and actual results could vary materially from our expectations, which may adversely affect our capital resources and liquidity. We could utilize our available capital resources sooner than we currently expect. The amount and timing of future funding requirements, both near- and long-term, will depend on many factors, including, but not limited to:

In addition, we are closely monitoring inflation rates and global political and economic conditions, including the ongoing wars between Russia and Ukraine and between Israel and Hamas, and evaluating adjustments to our business and operations, which may negatively impact our financial condition and prospects and our operating results. We will continue to assess our operating capital requirements and may make adjustments to our business and operations if circumstances warrant. If we cannot continue or expand our research, manufacturing and development operations, or otherwise capitalize on our business opportunities, because we lack sufficient capital, our business, operations, financial condition and prospects could be materially adversely affected.

Contractual Obligations and Commitments

We lease certain office, laboratory, and manufacturing space under non-cancelable operating leases. In addition to rent, our leases are subject to certain fixed amenities fees. These leases are also subject to additional variable charges for common area maintenance, property taxes, property insurance and other variable costs. See Note 8 of the consolidated financial statements for additional detail.

Total undiscounted aggregate future operating lease obligations under all of our operating leases as of December 31, 2023 are $162.9 million.

On May 15, 2018, we entered into the Amended MSKCC License with MSKCC. In the event a licensed product achieves a specified clinical milestone, MSKCC is then eligible to receive certain milestone payments totaling up to $75.0 million based on the price of our common stock, where the amount of such payments owed to MSKCC is contingent upon certain increases in the price of our common stock following the date of achievement of such clinical milestone. See Note 2 of the consolidated financial statements for additional detail.

As of December 31, 2023, we recorded a liability of $1.3 million associated with the remaining stock price appreciation milestones for the Amended MSKCC License.

We have no material contractual obligations not fully recorded on our consolidated balance sheets or fully disclosed in the notes to the financial statements.

We have obligations under various license agreements to make future payments to third parties that become due and payable on the achievement of certain development, regulatory and commercial milestones (such as the start of a clinical trial, filing for product approval with the FDA or other regulatory agencies, product approval by the FDA or other regulatory agencies, product launch or product sales) or on the sublicense of our rights to another party. We have not included these commitments on our balance sheet because the achievement and timing of these events is not fixed and determinable. Certain milestones are in advance of receipt of revenue from the sale of products and, therefore, we may require additional debt or equity capital to make such payments. These commitments include:

We enter into contracts in the normal course of business, including with clinical sites, CROs, and other professional service providers for the conduct of clinical trials, contract manufacturers for the production of our product candidates, contract research service providers for preclinical research studies, professional consultants for expert advice and vendors for the sourcing of clinical and laboratory supplies and materials. These contracts generally provide for termination on notice, and therefore are cancelable contracts and not included in the table of contractual obligations and commitments.

Inflation

Inflation has increased during the periods covered by this Annual Report on Form 10-K, and may continue to increase or remain elevated for the near future. Inflationary factors, such as increases in the prices of material, interest rates and cost of labor may adversely affect our operating results. Although we do not believe that inflation has had a material impact on our financial position or results of operations to date, we may experience some effect in the near future, especially if inflation rates continue to rise.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Fate Therapeutics, Inc. as of December 31, 2023 and 2022, the related consolidated statements of operations and comprehensive loss, convertible preferred stock and stockholders’ equity and cash flows for each of the two years in the period ended December 31, 2023, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
