About this update from Lyell Immunopharma, Inc.
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 unaudited Condensed Consolidated Financial Statements and the related notes included elsewhere in this Quarterly Report on Form 10-Q, and our audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2025 and the related Management's Discussion and Analysis of Financial Condition and Results of Operations, both of which are contained in our 2025 Annual Report on Form 10-K for the year ended December 31, 2025, filed with the Securities and Exchange Commission (SEC) on March 12, 2026 (the 2025 Annual Report). This discussion and analysis and other parts of this Quarterly Report on Form 10-Q contain forward-looking statements based upon current beliefs, plans and expectations related to future events and our future financial performance that involve risks, uncertainties and assumptions, such as statements regarding our intentions, plans, objectives and expectations for our business. Our actual results and the timing of selected events could differ materially from those described in or implied by these forward-looking statements as a result of several factors, including those set forth in the section titled "Risk Factors" in Part II, Item 1A of this Quarterly Report on Form 10-Q. See also the section titled "Special Note Regarding Forward-Looking Statements." Overview We are a late-stage clinical cell therapy company advancing a pipeline of proprietary next-generation autologous CAR T-cell product candidates for patients with cancer. Our goal is to fully realize the curative potential of cell therapy for patients with hematologic malignancies and solid tumors. To achieve this, we are pioneering novel approaches designed to generate T-cell therapies that drive long-lasting clinical responses. Our investigational CAR T-cell therapies start with the identification of promising cancer targets. We then engineer the patient's own living immune cells and arm them with our innovative enhancements, including CAR constructs, technologies or manufacturing protocols that are designed to endow T cells with more potent cancer cell killing capabilities. In hematologic malignancies, we are focused on delivering to patients meaningfully improved outcomes over currently approved, first-generation CD19 CAR T-cell products. Our lead product candidate, rondecabtagene autoleucel, or ronde-cel, is a dual-targeting CD19/CD20 CAR T-cell product candidate designed to increase complete response rates and prolong the duration of response as compared to the approved CD19-targeted CAR T-cell therapies. Ronde-cel is designed with a true 'OR' logic gate to target B cells that express either CD19 or CD20 with full potency at either target and is manufactured with a process that enriches for CD62L-positive cells to generate more naïve and central memory CAR T cells with enhanced stemlike features and antitumor activity. We are currently conducting two pivotal trials with ronde-cel. The first, PiNACLE, is a single-arm clinical trial that is a seamless expansion of the third- or later line (3L+) cohort in the Phase 1/2 trial. This trial is expected to report additional data in the second half of 2026 and pivotal data in mid-2027, with submission of a Biologics License Application (BLA) expected to follow in 2027. The PiNACLE trial is evaluating ronde-cel in patients with relapsed/refractory (R/R) LBCL receiving treatment in the 3L+ setting. We commenced dosing in the first-of-its-kind Phase 3 head-to-head CAR T-cell therapy randomized controlled trial, PiNACLE-H2H, for patients with LBCL receiving treatment in the second-line (2L) setting. Patients are randomized to either ronde-cel or investigator's choice of axicabtagene ciloleucel (axi-cel) or lisocabtagene maraleucel (liso-cel). To realize the potential of cell therapy for solid tumors, we acquired an exclusive global license for LYL273 (excluding mainland China, Hong Kong, Macau and Taiwan), a guanylyl cyclase C (GCC)-targeted CAR T-cell product candidate, from Innovative Cellular Therapeutics Holdings Limited and Innovative Cellular Therapeutics (collectively, ICT) in November 2025. A 67% overall response rate and an 83% disease control rate with a manageable safety profile have been reported at the highest dose level tested in patients with 3L+ R/R mCRC in a U.S. Phase 1 clinical trial as of the data cutoff date of October 28, 2025. In June 2026, updated safety data from the ongoing trial were shared. The protocol was recently amended to a Phase 1/2 design to enable seamless expansion into a potential pivotal single-arm Phase 2 trial, pending regulatory alignment, and adds new cohorts, including a 2L cohort and a cohort evaluating a combination strategy with radiotherapy. LYL273 is enhanced with CD19 CAR expression and controlled cytokine release designed to improve CAR T-cell expansion, immune cell infiltration and cancer cell killing in the hostile tumor microenvironment. Clinical proof-of-concept for this program was initially demonstrated in 15 patients with mCRC in an investigator-sponsored clinical trial conducted in China and published in JAMA Oncology (September 2024). We were incorporated in June 2018. We wholly own and operate the LyFE Manufacturing Center TM (LyFE) capable of providing clinical trial material for our ongoing clinical trials, as well as for commercial launch. We expect LyFE to have the capacity to manufacture more than 1,200 CAR T-cell doses/year. Our primary activities to date have included clinical development of investigational T-cell therapies, conducting research and development, building and operating LyFE, acquiring technology, entering into strategic collaboration and license agreements, enabling and executing manufacturing activities in support of our product candidate development efforts, executing clinical trials, organizing and staffing the company, business planning, establishing and maintaining our intellectual property portfolio, regulatory submissions and other preparations to initiate and execute clinical trials, raising capital and providing general and administrative support for these activities. Our pipeline of next-generation CAR T-cell product candidates target cancers with large unmet need and is summarized in Table 1 below: Table 1 : Lyell's Pipeline 2L, second line; 3L+, third- or later-line; BLA, Biologics License Application; CAR, chimeric antigen receptor; CD62L+, CD62L or L-selectin positive T cells; CRC, colorectal cancer; EOP1, End-of-Phase 1; GCC, guanylyl cyclase C; LBCL, large B-cell lymphoma. Our Pipeline Programs Rondecabtagene Autoleucel (ronde-cel): A next-generation dual-targeting CD19/CD20 CAR T-cell product candidate designed to increase complete response rates and prolong the duration of responses as compared to the approved CD19-targeted CAR T-cell therapies for the treatment of large B-cell lymphoma. Our lead program, ronde-cel, is targeting patients with aggressive R/R large B-cell non-Hodgkin lymphoma (NHL), more commonly referred to as LBCL. Lymphoma is a blood cancer that begins in lymphocytes and spreads primarily in lymph nodes, but can also metastasize to the liver, kidney, brain and other organs. NHL is the more common form of lymphoma, representing approximately 90% of all lymphomas. We are initially focused on developing ronde-cel for the treatment of patients with NHL subtypes representing approximately 35% of the over 80,000 patients estimated to be diagnosed with NHL in the United States in 2025 and 545,000 patients worldwide. The NHL subtypes we are currently pursuing include diffuse large B-cell lymphoma (DLBCL), high grade B-cell lymphoma (HGBCL), primary mediastinal large B-cell lymphoma (PMBCL), transformed follicular lymphoma (tFL), transformed marginal zone B-cell lymphoma (tMZBCL), transformed mantle cell lymphoma (tMCL) and Grade 3B follicular lymphoma (FL3B). DLBCL represents approximately 31% of patients diagnosed with NHL each year (of which approximately 5% are HGBCL). PMBCL represents approximately 3% and FL3B and the transformed lymphomas represent approximately 1 to 2% of patients diagnosed with NHL each year. We may choose to further expand development to include additional NHL subtypes in the future. The worldwide sales for currently approved CD19 CAR T-cell products are expected to exceed $5 billion by 2030 (Figure 1). Of the approximately 30,000 patients in the U.S. with LBCL, 40% to 50% are refractory to, or relapse following, first-line treatment and we estimate approximately 12,000 to 15,000 patients in the United States with LBCL progress to 2L treatment. We estimate the 3L+ patient population to be approximately 6,000 to 7,000 patients. This estimate reflects findings from a retrospective analysis presented by investigators from Memorial Sloan Kettering Cancer Center that up to 50% of patients with LBCL who progress on first-line therapy received a second regimen of chemotherapy prior to undergoing leukapheresis for CAR T-cell therapy. In a separate Medicare fee-for-service claims analysis, a similar percentage (57%) of patients with LBCL classified as receiving CAR T-cell therapy in the 2L been administered a second chemotherapy regimen prior to CAR while awaiting referral and/or scheduling for leukapheresis (Figure 2).

While the first generation of CD19 CAR T-cell therapies delivered a major advance in treatment for patients with B-cell lymphoma, there remains a need for therapies that deliver more complete and durable responses. More than 40% of patients with aggressive LBCL treated in the 3L+ setting with a CD19 CAR T-cell therapy are not disease-free after treatment and 30% of patients do not respond at all. Of these patients treated with an approved CD19 CAR T-cell therapy, approximately 50% of patients progress or die within six months, and the overall survival at one year for patients treated with a CD19 CAR T-cell therapy is only 50% to 60%. The median progression-free survival for the approved CD19 CAR T-cell therapies for patients in the 3L+-setting is 6 to 7 months. The ZUMA-7 randomized controlled trial of axi-cel versus standard of care chemoimmunotherapy in the 2L setting demonstrated a complete response rate of 65% and a median progression-free survival in all enrolled patients of 14.7 months. For those patients with primary refractory disease, the median progression-free survival was only 7 months as reported in an abstract. The complete response rate for patients with primary refractory disease was not reported. The median event-free survival in all patients was 8.3 months. Importantly, this study did not allow patients to receive bridging therapy other than steroids between leukapheresis and CAR T-cell therapy infusion, potentially excluding patients who were progressing too rapidly to wait for CAR T-cell therapy. Liso-cel was evaluated in two pivotal trials conducted in the 2L setting. The first pivotal trial was a randomized controlled trial of liso-cel versus standard-of-care chemoimmunotherapy (TRANSFORM), which did not enroll patients over the age of 75 but did allow bridging therapy with chemotherapy. The complete response rate was 66% and the median progression-free survival was 14.8 months, and the median event-free survival was 10.1 months in the liso-cel arm. Data for patients with primary refractory disease in the 2L were not published from this trial; however, a poster presentation suggested these younger patients (median age of 61 years) with low disease volume (9% of patients with a Sum of Product Diameter > 50 cm 2 ) had similar clinical outcomes between primary refractory and relapsed subgroups. The second pivotal single-arm trial conducted for liso-cel (PILOT), did allow patients over the age of 75 to enroll and included patients ineligible for transplant with primary refractory disease, relapse before 12 months or relapse after 12 months. The complete response rate in the overall patient population was 54% and was 42% in the primary refractory patient population. The package insert for YESCARTA ® lists the rate of Grade 3 or higher cytokine release syndrome (CRS) as 9% and the rate of Grade 3 or higher neurotoxicity as 31%. The package insert for BREYANZI ® lists the rate of Grade 3 or higher CRS as 3% and the rate of Grade 3 or higher neurotoxicity as 10%. Ronde-cel is an autologous dual-targeting CD19/CD20 CAR T-cell therapy designed to kill B cells expressing CD19 and/or CD20 antigens for the treatment of patients with aggressive B-cell malignancies. We acquired this product candidate through our acquisition of ImmPACT Bio USA Inc. (ImmPACT) in October 2024. A dual-targeting, or bispecific, tandem CAR recognizes two targets with a single construct. Ronde-cel is rationally designed with a true CD19/CD20 "OR" logic-gated CAR targeting either CD19 or CD20 with full potency at either target, and the cell therapy product is enriched for naïve and central memory T cells. Together, this novel construct and the cell enrichment for naïve and central memory T cells are designed to provide multiple clinical benefits over CD19 CAR T-cell therapies, including: • Ability to target lower or heterogeneous CD19 antigen density and result in a higher percentage of complete responses than with a single-targeting CAR construct; • Increase in the duration of responses by preventing relapse due to CD19 antigen escape; and • Better cell expansion, persistence and reduced exhaustion to provide longer duration of responses. Ronde-cel consists of autologous T cells that are genetically modified through transduction with a lentiviral vector expressing a tandem CAR construct composed of anti-CD19 and anti-CD20 single-chain variable fragments (scFvs) in tandem and an intracellular portion that contains the T-cell signaling zeta chain (CD3-ζ) and the 4-1BB co-stimulatory domain (Figure 3). This differentiates ronde-cel from cell therapies and other therapeutic modalities that singularly target CD19, CD20 or CD22. Figure 3 : Ronde-cel contains separate, tandem scFv antibody domains designed to target both CD19 and CD20 and is manufactured using a CAR construct that contains a 4-1BB costimulatory domain and is manufactured with a process to enrich for CD62-positive naïve and central memory T cells. Antigen heterogeneity, which refers to variation in the expression levels of tumor antigens across cancer cells, can limit the effectiveness of targeted therapies, including CD19 CAR T-cell therapy. Nonclinical data demonstrated that ronde-cel's optimized tandem CAR design is capable of killing target cells that express CD19 only, CD20 only or both antigens with full potency, thus it has the potential to achieve a higher percentage of complete responses than a single-targeting agent, particularly in those patients with malignant B cells with a lower or heterogeneous CD19 antigen density. CD19 antigen escape, a mechanism by which tumor cells evade the host immune system or targeted therapy through loss, downregulation or modification of target antigens, is a known mechanism contributing to disease relapse. Ronde-cel's dual-targeting of both CD19 and CD20 was designed to overcome CD19 antigen escape and potentially prolong the duration of responses, as well as to target malignant B cells with limited or no expression of CD19 to achieve a higher overall response rate. In a nonclinical xenograft model of mixed tumor cells (75% CD19-positive/CD20-positive, 25% CD19-negative/CD20-positive), mice treated with CAR T cells that targeted CD19 and CD20 in this manner eliminated tumors and overcame a subsequent tumor re-challenge, whereas CD19 CAR T-cell treatment failed to control the tumors. Additionally, ronde-cel is manufactured to produce a CAR T-cell product with higher proportions of naïve and central memory T cells through a process that enriches for CD62L-expressing cells. CD62L is a surface protein that acts as a homing beacon, guiding white blood cells to sites of inflammation. CD62L enrichment in ronde-cel's manufacturing process substitutes for the CD4/CD8 enrichment step in traditional CAR T-cell manufacturing, and generates cell products that are comprised of more than 95% naïve or central memory T cells. This manufacturing process is designed to generate CAR T cells with enhanced antitumor activity, which we believe could result in both increased complete response rates and more durable responses. Naïve T cells are mature T lymphocytes that have differentiated in the bone marrow and undergone central tolerance selection in the thymus, but have not interacted with their antigen. CAR T cells generated from these CD62L-positive less differentiated T cells have been associated with better cell expansion, improved persistence, reduced exhaustion and lower adverse cytokine production compared to CAR T cells generated from traditional processes. The enrichment of CD62L-expressing T cells does not increase the manufacturing time, which is similar to that of the approved CD19 CAR T-cell therapies with a median vein to site time of 16 days. Data from the ZUMA-7 pivotal trial of axi-cel in patients with R/R LBCL demonstrated an improved overall survival in those patients with a higher median percentage of T cells with a naïve/stem memory phenotype in the administered cell product. Translational analyses were presented at the European Hematology Association Annual Congress in June 2026 (EHA 2026), providing a biological basis for ronde-cel's durable responses, including enhanced memory potential of cytotoxic effector cells from CD62L+ enrichment and CD19/CD20 dual-targeting to overcome low antigen expression. Ronde-cel Clinical Development Our ongoing Phase 1/2 trial of ronde-cel is a multi-cohort, multi-center, open-label dose-escalation and dose-expansion clinical trial designed to evaluate the safety and clinical benefit of ronde-cel (NCT05826535). We presented positive data, detailed below, from the 3L+ and 2L cohorts from the ongoing Phase 1/2 trial during an oral presentation at the American Society of Hematology Annual Meeting and Exhibition in December 2025 (ASH 2025). Based on these data, as well as our End-of-Phase 1 meetings with the U.S. Food and Drug Administration (FDA), we announced the initiation of two pivotal trials of ronde-cel: PiNACLE and PiNACLE-H2H. The PiNACLE trial, which is underway and enrolling patients, is a seamless expansion of the 3L+ cohort of our Phase 1/2 trial. PiNACLE is a single-arm trial evaluating ronde-cel at a dose of 100 x 10 6 CAR T cells in patients with LBCL treated in the 3L+ setting. The trial is expected to treat approximately 100 patients with R/R DLBCL, PMBCL, FL3B or tFL who have received two or more prior lines of therapy and have not received CAR T-cell therapy. Patients may be treated with ronde-cel in the inpatient or outpatient setting, with observation near the site limited to 14 days. There is no upper age limit for eligibility, which broadens the addressable patient population. The primary endpoint of the trial is the best overall response rate, including an evaluation of duration of response. More information about the PiNACLE trial can be found on clinicaltrials.gov (NCT05826535). Additional data from the PiNACLE trial are expected to be reported in the second half of 2026. Pivotal data from the PiNACLE trial are expected in mid-2027, with a BLA submission expected to follow in the second half of 2027. The PiNACLE-H2H trial is a first-of-its-kind Phase 3 head-to-head CAR T-cell therapy randomized controlled trial evaluating ronde-cel versus investigator's choice of approved CD19 CAR T-cell therapies (axi-cel or liso-cel) in patients with R/R LBCL receiving treatment in the 2L setting. Patients randomized to ronde-cel will be treated with a dose of 100 x 10 6 CAR T cells. The primary endpoint of the trial is event-free survival. The trial is expected to enroll approximately 400 patients with R/R LBCL (200 per arm), including DLBCL, PMBCL, HGBCL, FL3B, tFL, tMCL or tMZBCL who have not previously received CAR T-cell therapy. Patients may be treated with ronde-cel in either the inpatient or outpatient setting. Patient dosing commenced in February 2026, and clinical site activation is ongoing in the United States, Canada and Australia. More information about the PiNACLE-H2H trial can be found on clinicaltrials.gov (NCT07188558). A progress update from the PiNACLE-H2H trial is expected in the second half of 2026. Now that the PiNACLE-H2H trial is enrolling patients, the 2L cohort in our Phase 1/2 multi-cohort trial is no longer recruiting patients. In the future, we may expand into other types of B-cell NHL. Ronde-cel: Clinical Data We presented new clinical and translational data from our ongoing Phase 1/2 clinical trial of ronde-cel in patients with LBCL at ASH 2025. The trial is a multi-cohort, multi-center, dose-escalation, dose-expansion trial. Patients had not previously received CAR T-cell therapy and there was no upper age limit nor requirement for CD19/CD20 screening prior to enrollment. Data were presented from the 3L+ and 2L cohorts. Bridging therapy was optional and lymphodepletion included fludarabine, 30 mg/m 2 , and cyclophosphamide, 500 mg/m 2 , each for three days. The cell manufacturing median vein to site time was 16 days and the recommended Phase 2 dose was established at 100 x 10 6 CAR T cells. Two patients were treated at Dose Level 2 (300 x 10 6 CAR T cells). Imaging response assessments were conducted locally at Day 28, Month 3 and every three months for 24 months. The trial objectives were safety and tolerability, best overall response rate and complete response rate, duration of response, selection of the recommended Phase 2 dose and cell expansion pharmacokinetics. Sixty-nine patients with R/R LBCL received ronde-cel as of September 5, 2025 (the data cutoff date for the presentation at ASH 2025). Patient demographics and baseline disease characteristics were consistent with a high-risk, heavily pre-treated patient population, particularly as compared to historical trials of CD19 CAR T-cell products: median ages of 64 and 65 years with 16% (6/37) and 21% (5/24) of patients being 75 years or older in the 3L+ and 2L settings, respectively; and primary refractory disease in 43% (16/37) and 92% (22/24) of patients in the 3L+ and 2L settings, respectively. The efficacy evaluable population, defined as those patients with Day 84 assessments or prior disease progression or death, consisted of 47 patients (29 in the 3L+ setting and 18 in the 2L setting). Patients Treated with Ronde-Cel in the 3L+ Setting There were 29 efficacy-evaluable 3L+ patients with R/R LBCL (DLBCL, PMBCL, 3BFL or tFL) with a median follow-up time of 12 months as of the data cutoff date. The data are presented in Figure 4 and summarized here: • The best overall response rate was 93% (27/29 patients), with 76% (22/29) of patients achieving a complete response • 72% (13/18) of patients with complete response remained in complete response at 6 months or longer • Median progression-free survival was 18 months The PiNACLE single-arm pivotal trial is a seamless expansion of this 3L+ cohort and is ongoing. Patients with HGBCL are no longer included in the PiNACLE single-arm trial to focus the trial on those patients most likely to achieve high durable response rates. The response rate and duration of response in patients enrolled with HGBCL (N = 8) was shorter than that observed for patients with other histologies. Figure 4 : High rates of durable complete responses were observed in patients treated with ronde-cel in the 3L+ setting. 3L+, third- or later-line setting, LBCL, large B-cell lymphoma. Patients Treated with Ronde-Cel in the 2L Setting There were 18 efficacy-evaluable patients enrolled in the 2L setting with a median follow-up time of 9 months as of the data cutoff date. Of these efficacy-evaluable patients, 94% had primary refractory disease. Data from these patients are presented in Figure 5 and summarized here: • The overall response rate was 83% (15/18 patients), with 61% (11/18) achieving a complete response • 70% (7/10) of patients with complete response remained in complete response at ≥ 6 months • The median duration of complete response was not reached Figure 5 : High rates of durable complete responses were observed in patients treated with ronde-cel in the 2L setting. 2L, second-line setting, LBCL, large B-cell lymphoma. Safety Data Updated safety data from the Phase 1/2 trial were presented at EHA 2026. One hundred and eight patients with R/R LBCL received ronde-cel as of the EHA 2026 data cutoff date of May 5, 2026. In 108 patients, including patients from both the 3L+ and the 2L cohorts, a manageable safety profile potentially appropriate for outpatient administration was observed. Sixty-four of the 108 patients (59%) received dexamethasone prophylaxis (10 mg/day for 3 days). No Grade 3 or higher CRS was reported in any patient. Five cases (8%) of Grade 3 or higher immune effector cell-associated neurotoxicity syndrome (ICANS) were reported in patients receiving dexamethasone prophylaxis. The median time to onset of CRS was 6 days and of ICANS was 7 days in those patients receiving prophylaxis. The median time to resolution of CRS or of ICANS was 3 days. Data are presented in Figure 6. Figure 6 : Adverse events of interest with and without dexamethasone prophylaxis for patients in both the 3L+ and 2L settings. CRS, cytokine release syndrome; HGBCL, high grade B-cell lymphoma; ICANS, immune effector cell-associated neurotoxicity; IEC-HS, immune effector cell-associated hemophagocytic lymphohistiocytosis-like syndrome; HLH, hemophagocytic lymphohistiocytosis; IV, intravenous; LDH, lactate dehydrogenase; PO, per os (oral). Ronde-cel demonstrated robust cell expansion with or without dexamethasone prophylaxis with no significant differences observed in peak CAR T-cell expansion (C max ) or overall exposure (AUC) between patients who received dexamethasone (N = 25) and those who did not (N = 42). Ronde-cel has received Regenerative Medicine Advanced Therapy (RMAT) designation as well as Fast Track designation from the FDA for the treatment of adults with R/R DLBCL in the 3L+ setting and has also received RMAT designation for the treatment of LBCL in the 2L setting. The FDA has also granted ronde-cel Orphan Drug Designation for the treatment of DLBCL/HGBCL with MYC and BCL2 rearrangements. LYL273: GCC-targeted CAR T-cell product candidate for the treatment of R/R mCRC and other GCC-expressing cancers In November 2025, we acquired an exclusive global license, outside of mainland China, Hong Kong, Macau and Taiwan, from ICT for a next-generation GCC-targeted CAR T-cell product candidate (LYL273) with promising dose-dependent clinical activity in patients with R/R mCRC in a Phase 1 trial conducted in the U.S. LYL273 is a GCC-targeted CAR T-cell product candidate enhanced with CD19 CAR expression and controlled cytokine release designed to improve CAR T-cell expansion, immune cell infiltration and cancer cell killing in the hostile solid tumor microenvironment. LYL273 was granted Fast Track designation for the treatment of mCRC by the FDA. Clinical proof-of-concept was initially demonstrated in an investigator-sponsored clinical trial conducted in China prior to the submission to the FDA of an Investigational New Drug Application. Data from this single-center clinical trial in 15 patients with mCRC conducted in China were published in JAMA Oncology (September 2024). In the ongoing U.S. Phase 1 clinical trial, as of the data cutoff date of October 28, 2025, the overall response rate was 50% (6 of 12 patients) and the disease control rate was 83% across both dose levels. At Dose Level 2, the highest dose tested, the overall response rate was 67%, including one patient with a pathological complete response, one patient with complete reduction in tumor volume of the target lesions (100% partial response) and two additional patients with confirmed partial responses (Figure 7). For patients treated at Dose Level 2, the disease control rate was 83%, and the median progression-free survival was 7.8 months. Additional data from patients treated in the 3L+ setting of the U.S. Phase 1 trial, and an End-of-Phase 1 FDA meeting, are expected in the second half of 2026. Figure 7 : Data shown are from 12 patients enrolled in the U.S. Phase 1 clinical trial, six at Dose Level 1 and six at Dose Level 2. The left panel depicts target tumor volume change from baseline (%) and the right panel depicts the best overall response and survival after CAR T-cell administration. We provided a safety update in June 2026 (data cutoff date of May 5, 2026) from the U.S. Phase 1 trial following the implementation of gastrointestinal (GI) prophylaxis and a new safety management plan because of previously reported dose-limiting toxicities in one patient at Dose Level 2, including Grade 3 diarrhea, Grade 4 enterocolitis and death from fungal sepsis 48 days post-infusion. Gastrointestinal prophylaxis consisted of infliximab, vedolizumab and budesonide after infusion and prior to symptom onset. Safety data from patients enrolled at Dose Levels 1 and 2 included data from 9 patients who did not receive GI prophylaxis and 10 patients who did receive prophylaxis. The median age of the patients enrolled was 52 years (range, 39 to 74), the patients had received a median of 4 prior lines of therapy for mCRC (range, 2 to 7) and all patients had microsatellite stable disease. No difference in patient demographics and disease characteristics were observed between the two groups. No Grade ≥ 3 or higher CRS, ICANS or diarrhea/colitis was reported in any patient receiving GI prophylaxis, across Dose Levels 1 and 2. Reports of Grade ≥ 2 or higher diarrhea/colitis decreased from 55% to 10% with GI prophylaxis. Grade 3 or higher diarrhea/colitis occurred in 22% (2/9) of patients who did not receive GI prophylaxis. Evaluation of GCC-CAR cell expansion kinetic data revealed that both peak GCC CAR T-cell expansion and overall exposure are similar with and without GI prophylaxis at Dose Levels 1 and 2. Based on the new safety data and cell expansion kinetics, we amended the Phase 1 U.S. trial to enable seamless expansion into a pivotal single-arm Phase 1/2 trial, pending FDA agreement. New centers are being activated to support trial expansion and new cohorts to explore LYL273 in patients with 2L mCRC and in combination with radiotherapy were also added. Colorectal cancer is the second leading cause of cancer deaths worldwide, and the incidence of colorectal cancer is rising in people younger than 55 years old. In the United States, there were estimated to be 154,000 total new colorectal cancer diagnoses and about 1 in 5 of these diagnoses will occur in people younger than 55 years old. Approximately 53,000 people were estimated to have died from CRC in the U.S. in 2025. Approximately 25% of patients have metastatic disease at the time of diagnosis and up to 60% of patients diagnosed with colorectal cancer will develop distant metastases at some point during their disease journey. Despite the remaining tremendous unmet medical need for new effective therapies for mCRC, the worldwide net sales for currently approved CRC products are expected to reach $12 billion by 2032 (Figure 8). However, the benefit of approved therapies for mCRC in the 3L+ setting is limited. With the approved products, only 6% or less of patients achieve a partial or complete response to their next line of therapy, the median progression-free survival is 6 months or less and the median overall survival is 11 months or less (Figure 8). Figure 8 : The worldwide market for therapies approved for colorectal cancer is six billion dollars and growing. However, currently approved standard-of-care therapies in the 3L+ setting do not achieve meaningful response rates and provide limited survival benefit. Our Nonclinical Programs Cell therapy has demonstrated profound results in some patients suffering from hematologic malignancies, but there remains a need for therapies that deliver more complete and durable responses. Solid tumors are even more complex and have evolved multiple mechanisms to evade and ultimately resist clearance by the immune system. This has limited the use of cell therapy in solid tumors, which account for 90% of cancer deaths. And while there has been recent progress with new cell therapies approved for solid tumors, overall response rates and the duration of response remain low. We continue to invest in earlier stage cell therapy research and development utilizing our proprietary technologies. We are advancing a fully-armed solid tumor CAR T-cell product candidate with an undisclosed target, with the CAR T cells enhanced by multiple technologies, each designed to address different barriers to effective cell therapies, including T-cell exhaustion, lack of durable stemness, as well as immune suppression within the hostile tumor microenvironment. Macroeconomic Environment Our business and operations may be affected by worldwide economic conditions, which may continue to be impacted by global macroeconomic challenges such as the effects of disruption between the U.S. and its trading partners due to tariffs or other policies, ongoing geopolitical conflicts (including military conflicts, threatened hostilities and conflicts or heightened tension in geopolitical relations) and related U.S. involvement, inflationary pressures, fluctuations in the interest rate environment, instability in the banking industry, supply constraints and overall market volatility. Economic uncertainty may persist throughout the remainder of 2026, and the market dynamics and potential business disruptions discussed above and similar adverse conditions may negatively impact our business. For a further discussion of trends, uncertainties and other factors that could impact our operating results, see the section entitled "Risk Factors" in Part II, Item 1A of this Quarterly Report on Form 10-Q. Components of Results of Operations Revenue We have no products approved for sale and have never generated any revenue from product sales. In the future, we may generate additional revenue from collaborations, strategic alliances, licensing agreements, product sales, or a combination of these. Operating Expenses Research and Development To date, research and development expenses consist of costs incurred by us for the discovery and development of our technology platforms and product candidates and include costs incurred in connection with conducting and completing current and planned clinical trials, strategic collaborations, costs to license technology, personnel-related costs, stock-based compensation expense, facility and technology related costs, research and laboratory expenses and other expenses, including consulting fees and other costs. Upfront payments and milestones paid to third parties in connection with technology platforms that have not reached technological feasibility and do not have an alternative future use are expensed as incurred. We deploy our employee and infrastructure resources across multiple research and development programs for identifying and developing product candidates and establishing manufacturing capabilities. These include costs for personnel, laboratory and other indirect facility and operating costs. Research and development activities account for a significant portion of our operating expenses. We anticipate that our research and development expenses will increase over the foreseeable future as we expand our research and development efforts including completing nonclinical studies, commencing planned clinical trials, conducting and completing current and planned clinical trials, seeking regulatory approvals of our product candidates, identifying new product candidates and incurring costs to acquire and license technology platforms. A change in the outcome of any of these variables could mean a significant change in the costs and timing associated with the development of our product candidates. Because we are early in our research and clinical development efforts of our product candidates, and the outcome of these efforts is uncertain, we cannot estimate the actual amounts necessary to successfully complete the nonclinical development, clinical development and commercialization of product candidates or whether, or when, we may achieve profitability. Our research and development expenses may vary significantly based on factors such as: • the number and scope of nonclinical and IND-enabling studies; • per patient trial costs; • the number of trials required for approval; • the number of sites included in the trials; • the countries in which the trials are conducted; • the length of time required to enroll eligible patients; • the number of patients that participate in the trials; • the drop-out or discontinuation rates of patients in the trials; • potential additional safety monitoring requested by regulatory agencies; • the duration of patient participation in the trials and follow-up; • the cost and timing of manufacturing our product candidates; • the phase of development of our product candidates; • the efficacy and safety profile of our product candidates; • the extent to which we establish additional collaboration or license agreements; and • whether we choose to partner any of our product candidates and the terms of any such partnership. A change in the outcome of any of these variables with respect to the development of any of our product candidates could significantly change the costs and timing associated with the development of that product candidate. We may never succeed in obtaining regulatory approval for any of our product candidates. We may obtain unexpected results from our nonclinical studies and clinical trials. General and Administrative General and administrative costs include personnel-related expenses, including stock-based compensation expense for personnel in executive, legal, finance and other administrative functions, legal costs, transaction costs related to licensing and collaboration agreements, as well as fees paid for accounting and tax services, consulting fees and facilities costs not otherwise included in research and development expenses. Legal costs include those related to corporate, dispute and patent matters. We anticipate that our general and administrative expenses will increase over the foreseeable future to support our continued research and development activities, operations generally, future business development opportunities, consulting fees, as well as the costs of operating as a public company such as costs related to accounting, audit, legal, regulatory and tax-related services associated with maintaining compliance with exchange listing and SEC requirements, director and officer insurance costs and investor and public relations costs. Other Operating (Income) Loss, Net Other operating (income) loss, net consists primarily of service and occupancy fees received associated with subleases as well as losses on the retirement of property and equipment. Impairment of Long-Lived Assets Impairment of long-lived assets consists of the expense associated with our 2025 impairment of our West Hills, Los Angeles lease right-of-use asset. The impairment loss is measured as the amount by which the carrying value of the asset group exceeded its fair value. Interest Income, Net Interest income, net consists primarily of interest earned on our cash, cash equivalents and marketable securities balances. Other Income, Net Other income, net consists primarily of the changes in fair value of our success payment liabilities for the three months ended June 30, 2026, and the changes in fair value of our success payment liabilities and SPA put/call (defined below) for the six months ended June 30, 2026. Other income, net consists primarily of the changes in fair value associated with our contingent consideration payable related to the ImmPACT acquisition and success payment liabilities for the three and six months ended June 30, 2025. The SPA put/call refers to a combined financial instrument arising from the Securities Purchase Agreement (SPA) we entered into in July 2025. It represented (i) our right to require certain investors to purchase additional shares of common stock upon the achievement of specified milestones and (ii) the investors' reciprocal right to purchase additional shares. Because these rights were mutually exclusive, they were accounted for as a single financial instrument (SPA put/call). The SPA put/call was settled in March 2026 upon the Milestone Closing and, accordingly, no changes in its fair value were recognized subsequent to settlement. See Note 7, Fair Value Measurements , in the accompanying notes to our unaudited condensed consolidated financial statements included in Part I, Item 1, of this Form 10-Q for additional information. See Note 3, Asset Acquisitions and Contingent Consideration regarding contingent consideration payable, Note 4, License, Collaboration and Success Payment Agreements regarding our success payment liabilities and associated expenses and Note 7, Fair Value Measurements regarding our SPA put/call in the accompanying notes to our unaudited condensed consolidated financial statements included in Part I, Item 1 of this Form 10-Q for additional information.

The $4.7 million increase was due primarily to a $8.8 million increase in research activities, collaborations and outside services due to increased clinical trial activity, partially offset by a $1.6 million decrease in personnel-related expenses and a $2.6 million reduction in facilities, technology and depreciation expenses primarily due to lower headcount associated with the successful technology transfer of ronde-cel to LyFE in 2025 and reduced depreciation expenses. Research and development expenses were $76.1 million and $78.3 million for the six months ended June 30, 2026 and 2025, respectively. The $2.2 million decrease was due primarily to a decrease of $9.1 million in personnel expenses and $5.3 million in facilities, technology and depreciation costs primarily due to lower headcount associated with the successful technology transfer of ronde-cel to LyFE in 2025 and reduced depreciation expenses, partially offset by a $12.2 million increase in research activities, collaborations and outside services due primarily to increased clinical trials activity. General and Administrative Expenses General and administrative expenses were $9.6 million and $9.8 million for the three months ended June 30, 2026 and 2025, respectively. The $0.2 million decrease was primarily due to a decrease in professional and outside services expenses. General and administrative expenses were $19.1 million and $23.8 million for the six months ended June 30, 2026 and 2025, respectively. The $4.7 million decrease was primarily due to a $3.8 million reduction in personnel costs, including a $1.9 million decrease in stock-based compensation expense, primarily due to decreased headcount from the successful technology transfer of ronde-cel in 2025, in addition to a decrease in professional and outside services expenses. Other Operating (Income) Loss, Net Other operating (income) loss, net was $(1.8) million and $1.1 million for the three months ended June 30, 2026 and 2025, respectively, and $(3.7) million and $0.9 million for the six months ended June 30, 2026 and 2025, respectively. The changes of $2.8 million and $4.6 million for the three and six months ended June 30, 2026, respectively, were primarily due to increased sublease income and reduced losses on disposals of property and equipment; we recognized $2.5 million and $3.8 million of such losses for the three and six months ended June 30, 2025, respectively, primarily in connection with the closure of the West Hills facility in 2025 following the technology transfer of ronde-cel. Impairment of Long-lived Assets Impairment of long-lived assets was $1.4 million for the three and six months ended June 30, 2025, consisting of the impairment of our West Hills, Los Angeles right-of-use lease asset resulting from the closure of the facility subsequent to the successful transition of the manufacturing of ronde-cel to our LyFE Manufacturing Center TM . No impairment was recognized for the three and six months ended June 30, 2026. Interest Income, Net Interest income, net was $2.2 million and $3.3 million for the three months ended June 30, 2026 and 2025, respectively, and $4.4 million and $7.1 million for the six months ended June 30, 2026 and 2025, respectively. The decrease in interest income, net for the three and six months ended June 30, 2026 was primarily driven by decreased interest rates in 2026 coupled with lower cash equivalent and marketable securities balances. Other Income, Net Other income, net was $0.4 million and $1.2 million for the three months ended June 30, 2026 and 2025, respectively. The decrease of $0.8 million was primarily due to a $0.9 million gain recognized in the prior year period from the change in fair value of our contingent consideration payable related to the ImmPACT acquisition that did not recur. Other income, net was approximately $18.3 million and $2.5 million for the six months ended June 30, 2026 and 2025, respectively. The increase of $15.8 million was primarily driven by a $17.6 million gain from the change in fair value of our SPA put/call, which was settled in the first quarter of 2026 upon the Milestone Closing, partially offset by a $2.1 million gain recognized in the prior year period from the change in fair value of our contingent consideration payable that did not recur. Liquidity and Capital Resources Sources of Liquidity Since our inception, we have funded our operations primarily through the sale and issuance of convertible preferred stock, business development activities and the sale of common stock in connection with our IPO, in a private placement financing and pursuant to an at-the-market offering program discussed below. As of June 30, 2026, we had $228.0 million in cash, cash equivalents and marketable securities excluding restricted cash. Since our inception, we have incurred significant operating losses. We have not yet commercialized any product candidates, and we do not expect to generate revenue from sales of any product candidates for a few years, if ever. We had an accumulated deficit of $1.7 billion as of June 30, 2026. From June 29, 2018 (inception) through June 30, 2026, we raised an aggregate of $1.5 billion in gross proceeds primarily from the sales of our convertible preferred stock, our IPO and private placements in July 2025 and March 2026 of our common stock pursuant to the SPA. In February 2024, we entered into a sales agreement (Sales Agreement) with TD Securities (USA) LLC (formerly known as Cowen and Company, LLC) (TD Cowen) as our sales agent with respect to an at-the-market offering program. In accordance with the terms of the Sales Agreement, we may offer and sell from time to time through TD Cowen shares of our common stock having an aggregate offering amount of up to $150.0 million (the Placement Shares). Sales of the Placement Shares are made at prevailing market prices on Nasdaq at the time of sale, or as otherwise agreed with the Agent, by any method permitted by law deemed to be an "at-the-market offering" as defined in Rule 415 of the Securities Act of 1933, as amended (the Securities Act). We pay commissions to TD Cowen of up to 3% of the gross proceeds of the sale of the Placement Shares sold under the Sales Agreement and reimburse TD Cowen for certain expenses. Neither us nor TD Cowen is obligated to sell any shares. During the six months ended June 30, 2026, we sold 65,092 shares of our common stock under the Sales Agreement for net proceeds of approximately $1.7 million. No shares were sold during the three months ended June 30, 2026 or the three and six months ended June 30, 2025. Securities Purchase Agreement On July 25, 2025, we issued 3,753,752 shares of common stock at a purchase price of $13.32 per share at an initial closing pursuant to the SPA for gross proceeds of approximately $50.0 million. On March 6, 2026, we issued 1,952,360 shares of common stock at a purchase price of $25.61 per share at a subsequent closing pursuant to the SPA for gross proceeds of approximately $50.0 million. Future Funding Requirements We expect to incur additional losses in the foreseeable future as we conduct and expand our research and development efforts, including conducting nonclinical studies and clinical trials, developing new product candidates, establishing, improving and maintaining internal manufacturing capabilities and funding our operations generally. Based on our current operating plan, we believe that our existing cash, cash equivalents and marketable securities will be sufficient to meet our working capital and capital expenditure needs for at least the next 12 months. However, we anticipate that we will need to raise additional capital in the future to fund our operations, including further development of our product candidates and the commercialization of any approved product candidates. In addition, we regularly consider fund-raising opportunities and may decide, from time to time, to raise additional capital, including pursuant to the Sales Agreement, based on various factors, including market conditions and our plans of operation. We are subject to the risks typically related to the development of new products, and we may encounter unforeseen expenses, difficulties, complications, delays and other unknown factors that may adversely affect our business. Our future capital requirements will depend on many factors, including: • the scope, timing, progress, costs and results of discovery, nonclinical development and clinical trials for our current and future product candidates and any additional nonclinical studies; • the number of clinical trials required for regulatory approval of our current and future product candidates; • the costs, timing and outcome of regulatory review of any of our current and future product candidates; • the cost of manufacturing clinical and commercial supplies of our current and future product candidates, including increases in these costs as a result of tariffs; • the costs and timing of future commercialization activities, including manufacturing, marketing, sales and distribution, for any of our product candidates for which we receive marketing approval; • further investment to build additional manufacturing facilities or expand the capacity of our existing ones; • the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims; • our ability to maintain existing, and establish new, collaborations, licenses, product acquisitions or other strategic transactions and the fulfillment of our financial obligations under any such agreements, including the timing and amount of any success payment, future contingent payments, milestone, royalty or other payments due under any such agreement; • the revenue, if any, received from commercial sales of our product candidates for which we receive marketing approval; • expenses to attract, hire and retain skilled personnel; • the costs of operating as a public company, including legal, accounting and other related expenses as well as costs relating to maintaining or expanding our operational, financial and management systems; • addressing or responding to any potential disputes or litigation; • the extent to which we acquire or invest in businesses, products and technologies; and • integration of any new businesses, products and technologies, such as LYL273, into our business. Until such time as we complete nonclinical and clinical development and receive regulatory approval of our product candidates and can generate significant revenue from product sales, if ever, we expect to finance our operations from the sale of additional equity or debt financings, or other capital that comes in the form of strategic collaborations, licensing, or other arrangements. In the event that additional capital is required, we may not be able to raise it on terms acceptable to us, or at all. If we raise additional funds through the issuance of equity or convertible debt securities, including pursuant to the Sales Agreement, it may result in dilution to our existing stockholders. Debt financing or preferred equity financing, if available, may result in increased fixed payment obligations, and the existence of securities with rights that may be senior to those of our common stock. If we incur indebtedness, we could become subject to covenants that may restrict our operations. If we raise funds through strategic collaboration, licensing or other arrangements, we may relinquish significant rights or grant licenses on terms that are not favorable to us. Our ability to raise additional funds may be adversely impacted by potential worsening global economic conditions and disruptions to, and volatility in, the credit and financial markets in the United States and worldwide resulting from tariffs, actual or perceived changes in interest rates and economic inflation, and otherwise. If we are unable to raise additional capital when desired, our business, results of operations and financial condition would be adversely affected. Material Cash Requirements We continually evaluate our liquidity and capital resources to ensure that we can adequately and efficiently finance our operations. As of June 30, 2026, our material cash requirements consisted primarily of paying salaries and benefits, administering clinical trials, conducting research, improving our manufacturing capabilities, providing the technology and facilities necessary to support our operations, funding operating lease obligations and other payments related to our license and collaboration agreements and the acquisitions of ImmPACT and our LYL273 license. See Note 3, Asset Acquisitions and Contingent Consideration , Note 4, License, Collaboration and Success Payment Agreements , and Note 8, Leases , in the accompanying notes to the unaudited condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q, for additional information. Cash Flows The following table summarizes our cash flows for the periods indicated (in thousands): Six Months Ended June 30, 2026 2025 Net cash (used in) provided by: Operating activities $ (72,432) $ (89,196) Investing activities 32,994 82,113 Financing activities 52,244 184 Net increase (decrease) in cash, cash equivalents and restricted cash $ 12,806 $ (6,899) Operating Activities During the six months ended June 30, 2026, net cash used in operating activities was $72.4 million, reflecting our net loss of $68.9 million, in addition to non-cash items primarily related to the gain on the SPA put/call of $17.6 million and non-cash lease income of $2.3 million, partially offset by stock-based compensation expense of $8.8 million and depreciation and amortization expense of $4.6 million. Additionally, changes in net operating assets and liabilities of $5.3 million partially offset the net cash used in operating activities. During the six months ended June 30, 2025, net cash used in operating activities was $89.2 million, reflecting our net loss of $94.9 million, partially offset by $16.1 million of non-cash items primarily related to stock-based compensation expense of $11.0 million, depreciation and amortization expense of $6.6 million and losses on property and equipment disposals of $3.8 million, partially offset by net amortization and accretion on marketable securities of $2.9 million and the change in the fair value of our contingent consideration payable of $2.1 million. Additionally, net operating assets and liabilities decreased $10.4 million primarily driven by a $13.1 million decrease in accrued liabilities and other current liabilities, partially offset by a $4.8 million increase in prepaid expenses, other current assets and other assets, which also contributed to the net cash used in operating activities. Investing Activities During the six months ended June 30, 2026 and June 30, 2025, cash provided by investing activities was $33.0 million and $82.1 million, respectively, consisting primarily of net maturities and purchases of marketable securities. Financing Activities During the six months ended June 30, 2026, cash provided by financing activities was $52.2 million, consisting primarily of $50.0 million of proceeds from the issuance of common stock under the SPA and $1.7 million from our at-the-market equity financing. During the six months ended June 30, 2025, cash provided by financing activities was approximately $0.2 million, consisting of proceeds from the employee stock purchase plan. Critical Accounting Policies and Estimates Our unaudited condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (GAAP). The preparation of these unaudited condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities at the date of the unaudited condensed consolidated financial statements, as well as the reported revenue and expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. There have been no material changes to our critical accounting policies and estimates as compared to those described in our 2025 Annual Report.
