(NASDAQ: FATE), a clinical-stage biopharmaceutical company dedicated to bringing a transformative pipeline of induced pluripotent stem cell (iPSC)-derived off-the-shelf cellular immunotherapies to patients for broad accessibility, today reported financial results for the fourth quarter and full year ended December 31, 2025, and provided a business update. “I am extremely proud of the progress the Fate team delivered in 2025, including bringing to fruition the treatment of FT819 off-the-shelf CAR T cells as outpatient therapy, eliminating the need for extended hospital stay requirements seen today with other CAR T-cell programs, which now uniquely expands autoimmune patient access, including in underserved regions, while significantly improving health system economics,” said Bob Valamehr, M.B.A., Ph.D., President and Chief Executive Officer of Fate Therapeutics. “I’m also pleased to note that we are continuing to progress towards the commencement of our first planned Phase 2 clinical trial in lupus nephritis, and we are actively recruiting patients in the Phase 1 basket study of FT819 across the U.S., U.K. and E.U., with the ultimate goal to advance FT819 to commercialization in various autoimmune diseases. Last year’s accomplishments are further highlighted by strong fourth-quarter clinical site activation, accelerated patient enrollment, expansion of FT819 into additional autoimmune diseases, the advancement of our next generation CAR T-cell programs, and continuation of our scientific leadership through quality conference presentations and manuscript publications. Importantly, additional clinical signals across autoimmune disease and in oncology without the use of conditioning chemotherapy are further validating the breadth of our platform. We have a well-capitalized balance sheet ensuring runway through 2027 and believe we are uniquely positioned to drive long-term value creation.” Clinical Development & Program Updates FT819 Off-the-Shelf CAR T-cell Program in Autoimmune Disease for Broad Patient Accessibility FT819 is an off-the-shelf CD19-targeting chimeric antigen receptor (CAR) T-cell product engineered to improve safety and efficacy. Analogous to master cell banks used to mass produce biopharmaceutical drug products such as monoclonal antibodies, a precisely engineered clonal master induced pluripotent stem cell (iPSC) bank serves as the starting cell source to manufacture FT819, overcoming numerous limitations associated with patient- and donor-sourced CAR T-cell therapies. FT819 is well-defined and uniform in composition, produced at a low cost of goods, and can be stored in inventory for off-the-shelf, on-demand availability to enable access for a broad patient population. FT819-102 Phase 1 clinical trial now enrolling in 16 clinical sites across the U.S., U.K. and E.U. The Company’s ongoing multi-center, Phase 1 clinical trial of FT819 (NCT06308978) is designed to evaluate the safety, pharmacokinetics, and efficacy of a single dose of FT819 following either i) Regimen A, a fludarabine (flu)-free less-intensive conditioning regimen, consisting of either bendamustine alone or cyclophosphamide alone, or ii) Regimen B, added to maintenance therapy without the use of conditioning chemotherapy. The disease indications in the basket study include systemic lupus erythematosus (SLE), anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV), idiopathic inflammatory myositis (IIM), and systemic sclerosis (SSc). Fifteen SLE patients across the two regimens have been treated, as of February 25 th ; Four SSc patients have also been treated in the two regimens as of February 25 th , with the first SSc patient treated with FT819 and less-intensive conditioning chemotherapy (Regimen A) exhibiting improvements in health assessment questionnaire (HAQ), clinician global assessment (CGA), patient global assessment (PtGA) and modified Rodnan skin score (mRSS) at the 3-month follow-up, as of February 9 th data cut off; and One IIM patient has also been treated, as of February 25 th . Clinical site expansion and enrollment across the study indications continue to accelerate with a focus on bringing on-demand accessibility of FT819 and outpatient treatment to community hospitals and infusion centers. The Company expects to provide clinical, regulatory, and operational updates in the second half of 2026. Successfully treated patients in FT819-102 clinical trial as outpatient treatment. This achievement represents a major clinical milestone: the successful dosing of autoimmune patients with FT819 off-the-shelf CAR T-cell therapy in an outpatient setting, without the need for extended hospitalization and observation. By eliminating the need for extended hospitalization and reducing or eliminating the use of conditioning chemotherapy, FT819 removes key logistical and clinical barriers that have limited autoimmune patient access to CAR T-cell therapies, facilitating broad patient access to such potentially transformative medicine. This unique ability for outpatient treatment of CAR T cells in autoimmune disease reflects meaningful clinical progress. Enabling a feasible treatment option in community hospital-based settings and plans for treatment in infusion centers has the potential to expand access to FT819 off-the-shelf CAR T cells to a broader patient population, facilitate service to underserved regions, reduce burden on healthcare infrastructure, and improve the scalability and practical delivery of CAR T-cell therapy. Data presented at the American Society of Hematology (ASH) Annual Meeting demonstrate meaningful and durable clinical responses, broad accessibility, and favorable safety pro FT819 in SLE. At the 2025 ASH Annual Meeting, the Company reported that 12 patients had been treated in the FT819-101 Phase 1 study, and provided clinical data for 10 patients with greater than 1 month follow-up as of a data cut off date of October 22, 2025, showing progressive and durable reductions in disease activity, including mean SLEDAI-2K score reductions of up to 78% by six months from the dose level 2 (DL2) cohort, complete renal responses in lupus nephritis, and sustained B-cell depletion with immune cell remodeling. FT819 was well tolerated with no dose limiting toxicities, no immune effector cell-associated neurotoxicity syndrome (ICANS) or graft-versus-host disease (GvHD), and only low-grade incidences of cytokine release syndrome (CRS), supporting outpatient, on-demand treatment. Next-generation off-the-Shelf CAR T-cell Program with Novel Sword & Shield™ Technology Designed to Eliminate the Need for Conditioning Chemotherapy Preclinical data demonstrates potent activity and functional persistence of FT836 across a broad array of cancers. FT836 is the Company’s multipoint-edited CAR T-cell product candidate uniquely targeting major histocompatibility complex (MHC) proteins A (MICA) and B (MICB). The expression of MICA/B cell-surface proteins is induced by cellular stress or malignant transformation and is detectable across many types of cancer cells with limited expression on healthy tissue. At the Society for Immunotherapy of Cancer (SITC) 40th Annual meeting held in November 2025, the Company presented preclinical data showing FT836 exhibited potent and durable CAR-dependent antigen-driven proliferation with robust activity across diverse solid tumors and that FT836 can be combined with standard of care chemotherapy to induce MICA/B surface expression for enhanced target recognition and additive antitumor activity. In addition, the Company presented immunohistochemistry analysis showing that MICA/B is expressed throughout tumor tissue in biopsy samples obtained from patients with various cancers, including colorectal cancer. FT836 is also the Company’s first product candidate to incorporate the novel Sword & Shield TM technology, which utilizes the Company’s novel alloimmune defense receptor (ADR) alongside CD58 knockout (KO), to both target and evade host alloreactive immune cells for a comprehensive strategy to avoid the need for conditioning chemotherapy. In January 2025, the Company secured a $4 million award from the California Institute of Regenerative Medicine (CIRM) to support IND-enabling activities for FT836. FT836 demonstrates clinical activity in CRC without the use of conditioning chemotherapy. In July, the FDA allowed the Company’s investigational new drug (IND) application to initiate Phase 1 clinical testing of FT836 off-the-shelf CAR T cells. The Phase 1 study is designed to assess the safety and activity of FT836 as monotherapy and in combination with standard of care therapies without administration of conditioning chemotherapy for the treatment of advanced solid tumors. The Company has now treated three colorectal cancer (CRC) patients with FT836 at DL1 of 300 million cells, given on Days 1 and 15, with the first dose requiring 24-hour hospitalization and the second dose being given as outpatient. FT836 was well-tolerated with no ICANS, GvHD, CRS or dose-limiting toxicities reported at DL1, supporting its potential as a broadly accessible treatment with a favorable safety profile. As of the January 23 rd 2026 data cut off, one of the three CRC patients treated in combination with cetuximab at DL1, a heavily pretreated 45 year old male who was refractory to cetuximab and had received 7 prior lines of therapy, demonstrated early evidence of anti-tumor activity, including a greater than 50% reduction in carcinoembryonic antigen (CEA) levels and significant reduction in lactate dehydrogenase (LDH) levels at Day 29 post treatment, with tumor reduction seen across all target lesions of approximately 20% decrease in the sum of diameters at the 46-day evaluation scan. Notably, these observations were achieved without conditioning chemotherapy, a capability of FT836 attributed to its Sword and Shield TM Technology. The clinical response is assessed on Day 56 and the patient is under consideration for a second treatment cycle. The ongoing clinical protocol trial is open to enrollment for treatment of patients with breast, colorectal, ovarian, head and neck, endometrial, gastric/gastroesophageal junction, and non-small cell lung cancers. The Company expects to provide additional clinical data updates in the second half of 2026. FT839 preclinical data presented at 2025 ASH Annual Meeting demonstrates broad targeting capacity across autoimmune diseases and hematologic malignancies without the need for conditioning chemotherapy. FT839 is the Company’s first multi-antigen dual-CAR T-cell product candidate that is designed to express two unique CARs: a first CAR targeting the B-cell lineage marker CD19 and the second CAR targeting the immune activation marker CD38, which is often found on aberrant T, NK and B cells. FT839 is the second program to contain the Company’s Sword and Shield TM technology. At the 2025 ASH Annual Meeting, the Company presented preclinical data demonstrating the ability of FT839, with its dual-CAR mechanism and unique ability to synergize with monoclonal antibodies and T-cell engagers through its incorporated hnCD16 Fc receptor and CD3 fusion receptor, respectively, to specifically eliminate a variety of pathogenic immune cell types without requiring conditioning chemotherapy, suggesting its potential to broadly treat complex autoimmune diseases and hematologic malignancies. The Company has created the FT839 master cell bank and is completing IND-enabling activities to support initial clinical investigation of FT839 for the treatment of autoimmune diseases and hematologic malignancies in 2026.

At the 2025 ASH Annual Meeting, the Company presented preclinical data demonstrating the ability of FT839, with its dual-CAR mechanism and unique ability to synergize with monoclonal antibodies and T-cell engagers through its incorporated hnCD16 Fc receptor and CD3 fusion receptor, respectively, to specifically eliminate a variety of pathogenic immune cell types without requiring conditioning chemotherapy, suggesting its potential to broadly treat complex autoimmune diseases and hematologic malignancies. The Company has created the FT839 master cell bank and is completing IND-enabling activities to support initial clinical investigation of FT839 for the treatment of autoimmune diseases and hematologic malignancies in 2026.

About Fate Therapeutics’ iPSC Product Platform Human induced pluripotent stem cells (iPSCs) possess the unique dual properties of unlimited self-renewal and differentiation potential into all cell types of the body. The Company’s proprietary iPSC product platform combines multiplexed-engineering of human iPSCs with single-cell selection to create clonal master iPSC lines. Analogous to master cell lines used to mass produce biopharmaceutical drug products such as monoclonal antibodies, the Company utilizes its clonal master iPSC lines as a starting cell source to manufacture engineered cell products which are well-defined and uniform in composition, can be stored in inventory for off-the-shelf availability, can be administered in combination with other therapies, and can potentially reach a broad patient population. As a result, the Company’s platform is uniquely designed to overcome numerous limitations associated with patient- and donor-sourced cell therapies. Fate Therapeutics’ iPSC product platform is supported by an intellectual property portfolio of over 500 issued patents and 500 pending patent applications. About Fate Therapeutics, Inc.
