(NASDAQ: IMTX, “Immatics” or the “Company”), a clinical-stage biopharmaceutical company and the global leader in precision targeting of PRAME, today provided a business update and reported financial results for the quarter ended September 30, 2025. “In the last months, we have achieved significant clinical milestones and solidified Immatics’ position as the PRAME leader across two modalities, cell therapies and bispecifics,” said Harpreet Singh, Ph.D., Chief Executive Officer and Co-Founder of Immatics. “With the recent data update and clinical proof-of-concept for our TCR Bispecifics pipeline, we’re entering the next exciting phase of bispecifics development while continuing to advance anzu-cel, our PRAME cell therapy, towards commercialization. At Immatics, our priority is the patients we serve, and every advancement in our clinical pipeline brings us closer to delivering meaningful and durable benefits to them through our innovative TCR-based therapeutics.” Third Quarter 2025 and Subsequent Company Progress PRAME Franchise – Cell Therapy Anzu-cel (IMA203) PRAME Cell Therapy – First Market Entry in Advanced MelanomaAnzu-cel (anzutresgene autoleucel), previously called IMA203, is Immatics’ lead PRAME cell therapy and will be the Company’s first PRAME therapy to enter the market in advanced melanoma. The current addressable patient population for anzu-cel’s first target indications, second-line or later (2L) cutaneous melanoma, as well as metastatic uveal melanoma, includes ~9,000 patients2. Phase 3 trial, SUPRAME, for anzu-cel (IMA203) in previously treated, advanced cutaneous melanoma Immatics’ global, randomized, controlled, multi-center Phase 3 clinical trial, SUPRAME, is currently ongoing to evaluate the efficacy, safety and tolerability of anzu-cel PRAME cell therapy as monotherapy vs. investigator's choice in patients with unresectable or metastatic cutaneous melanoma who have received prior treatment with a checkpoint inhibitor.SUPRAME is designed as a well-controlled clinical trial evaluating anzu-cel as a monotherapy in a late-stage cutaneous melanoma patient population and is intended to generate robust data to support regulatory approval of anzu-cel as Immatics advances this PRAME cell therapy towards the market.Primary endpoint for seeking full approval is blinded independent central review (“BICR”)-assessed (RECIST v1.1) progression-free survival (PFS). Secondary endpoints include overall survival (OS), objective response rate (ORR), safety and patient-reported outcomes about quality of life.Pre-specified interim and final data analyses will be triggered upon the occurrence of a defined number of events for PFS (progressive disease or death). Data from the interim analysis is not intended to be published to protect the integrity of the ongoing clinical trial.The Company remains on track for planned BLA submission in 1H 2027 and launch of anzu-cel in 2H 2027. Given the event-driven nature of the clinical trial design and based on the clinical site activation timelines, the target number of clinical trial sites and the current strong enrollment rate, Immatics estimates that the interim and final analyses will occur in 2026. Patient recruitment is currently ongoing in the US and Germany. The SUPRAME trial is planned to be conducted in more than 65 sites across North America and Europe, including the US, Germany, France, the Netherlands, the UK and Canada. Phase 1b trial for anzu-cel (IMA203) PRAME cell therapy in patients with metastatic melanoma A one-time infusion of anzu-cel PRAME cell therapy in all melanoma patients demonstrated favorable tolerability and promising clinical activity (Wermke et al., ASCO 2025): cORR of 56%; mDOR of 12.1 months at mFU of 13.4 months; mPFS of 6.1 months; mOS of 15.9 months Cutaneous melanoma subgroup, all post-checkpoint inhibitor, showed cORR of 50%, mDOR not reached at mFU of 16.7 months; mPFS of 6.0 monthsUveal melanoma subgroup, majority post-tebentafusp and checkpoint inhibitor, showed cORR of 67%, mDOR of 11.0 months at mFU of 13.4 months; mPFS of 8.5 months Phase 1/2 trial for anzu-cel (IMA203) PRAME cell therapy in patients with uveal melanoma On October 20, 2025, updated data from the Phase 1b trial of anzu-cel in a subgroup of 16 patients with metastatic uveal melanoma were presented by Sapna Patel, MD, at an oral presentation at the Presidential Symposium III at ESMO 2025. A one-time infusion of anzu-cel PRAME cell therapy in the 16 patients with uveal metastatic melanoma demonstrated favorable tolerability and continued strong anti-tumor activity and durability: cORR of 67%, mDOR of 11.0 months, mPFS of 8.5 months and mOS not reached at 14.3 months mFU.Based on the promising clinical data in patients with metastatic uveal melanoma, Immatics has initiated a Phase 2 cohort to treat approximately 30 uveal melanoma patients. The cohort is being conducted at select centers in the U.S. and Germany with deep expertise in uveal melanoma. The consistent favorable tolerability, anti-tumor activity and pharmacokinetic profile of anzu-cel across both cutaneous and uveal melanoma provide a strong rationale for pursuing a parallel late-stage development strategy to serve both patient populations.Anzu-cel has recently received Orphan Drug Designation (ODD) from the U.S. FDA for the treatment of uveal melanoma. Data on anzu-cel in advanced melanoma further substantiates Immatics’ global leadership in precision targeting of PRAME and the potential of anzu-cel to be the Company’s first PRAME product to enter the market. IMA203CD8 PRAME Cell Therapy (GEN2) – Expansion to all Advanced PRAME CancersIMA203CD8 is the Company’s second-generation PRAME cell therapy product candidate being developed with the goal of expanding into all advanced PRAME cancers. Given its enhanced pharmacology profile, once the target dose is reached, the Company intends to pursue the clinical development of this product candidate with a tumor-agnostic approach, starting with gynecologic cancers. Phase 1a dose escalation in solid tumors is ongoing to evaluate higher doses of IMA203CD8 with and without IL-2. The next clinical trial update, which will report on the continued dose escalation in multiple PRAME cancers, including ovarian cancer, melanoma and synovial sarcoma treated at relevant doses, will be presented on December 11, 2025, by Antonia Busse, M.D., Charité-CBF, at the ESMO Immuno-Oncology Congress 2025 during a mini oral presentation. PRAME Franchise - TCR Bispecifics IMA402 PRAME Bispecific – Expansion to Earlier-Line PRAME Cancers To expand the PRAME opportunity to earlier-line PRAME cancers, the Company is developing its off-the-shelf, next-generation, half-life extended TCR Bispecific, IMA402, as a monotherapy or in combination with standard of care, with a focus on melanoma and gynecologic cancers. In addition, Immatics is exploring the potential combination of IMA402 with IMA401 MAGEA4/8 Bispecific in squamous non-small cell lung cancer (sqNSCLC) and potentially other solid tumor indications. On November 12, 2025, Immatics announced updated data from the Phase 1a dose escalation clinical trial evaluating IMA402 in heavily pre-treated patients with solid tumors.The data showed clinical proof-of-concept of IMA402 with favorable tolerability across all doses, as well as deep and durable responses and early, promising PFS/iPFS and OS in patients treated within the RP2D range.Across all indications at RP2D range a 30% (6/20) cORR was observed, including 29% cORR (4/14) in melanoma and 2/3 confirmed responses in ovarian carcinoma.Based on the promising Phase 1a dose escalation data, Immatics is advancing its IMA402 PRAME Bispecific into Phase 1b dose expansion at two distinct doses to determine the final RP2D, both as a monotherapy and in combination with an immune checkpoint inhibitor with a focus on melanoma and gynecologic cancers in 2026.Depending on the outcomes of these Phase 1b cohorts, the Company would seek to convert existing Phase 1b cohorts into Phase 2 trials, which have the potential to become registration-directed.As part of its strategy to maximize the IMA402 opportunity, the Company is also exploring the option to initiate additional Phase 1b cohorts in 2026 to determine the monotherapy and combination potential of IMA402 with immune checkpoint inhibitors and standard of care in late as well as earlier treatment lines.As an additional opportunity, the Company is exploring the potential combination of IMA402 with IMA401 MAGEA4/8 in squamous non-small cell lung cancer (sqNSCLC) and potentially other solid tumor indications. IMA401 MAGEA4/8 Bispecific – Maximizing the Potential of Bispecifics CombinationsIMA401 is the Company’s off-the-shelf, next-generation, half-life extended TCR Bispecific targeting MAGEA4/8. Consistent with Immatics’ focus on advancing its PRAME Franchise, the Company is exploring IMA401 in combination with IMA402, starting with squamous non-small cell lung cancer (sqNSCLC). This opportunity with potentially synergistic clinical activity has the potential to address >90% of patients with sqNSCLC. On November 12, 2025, Immatics announced updated dose escalation data from the Phase 1a clinical trial evaluating IMA401 with or without an immune checkpoint inhibitor (pembrolizumab) in heavily pre-treated patients with solid tumors. The data showed clinical proof-of-concept with favorable tolerability at RP2D as well as promising clinical activity in patients in three focus indications treated with ≥1 mg: 25% cORR (2/8) in head and neck cancer, 29% cORR (2/7) in melanoma and promising clinical activity in sqNSCLC.Based on the clinical proof-of-concept of both bispecific candidates, including the initial promising activity of IMA401 in head and neck cancer and sqNSCLC, Immatics is well-positioned to assess the synergistic potential of combining two different bispecifics, IMA402 targeting PRAME and IMA401 targeting MAGEA4/8, with and without a checkpoint inhibitor. As over 90% of patients with sqNSCLC are positive for PRAME and/or MAGEA4/8, a potential IMA402 and IMA401 combination treatment could provide broad treatment coverage for this patient population. Approximately 60% of patients with sqNSCLC are positive for both targets, which could boost anti-tumor activity and counteract potential tumor escape mechanisms. The current addressable patient population for metastatic sqNSCLC in the United States and EU5 is an estimated 40,000 patients per year.

Third Quarter 2025 Financial Results Cash Position: Cash and cash equivalents as well as other financial assets total $505.8 million1 (€430.8 million) as of September 30, 2025, compared to $709.7 million1 (€604.5 million) as of December 31, 2024. The decrease is mainly due to ongoing research and development activities that is driven by $162.4 (€138.3) operational cash burn as well as unrealized foreign exchange translational losses of $41.6 million1 (€35.4 million), which do not impact the expected cash reach. Revenue: Total revenue, consisting of revenue from collaboration agreements, was $6.1 million1 (€5.2 million) for the three months ended September 30, 2025, compared to $59.4 million1 (€50.6 million) for the three months ended September 30, 2024. The decrease is mainly the result of a one-time revenue associated with the termination of the IMA401 collaboration by Bristol Myers Squibb during the three months ended September 30, 2024. Research and Development Expenses: R&D expenses were $55.4 million1 (€47.2 million) for the three months ended September 30, 2025, compared to $45.7 million1 (€38.9 million) for the three months ended September 30, 2024. The increase mainly resulted from costs associated with the advancement of the product candidates in clinical trials. General and Administrative Expenses: G&A expenses were $14.9 million1 (€12.7 million) for the three months ended September 30, 2025, compared to $13.1 million1 (€11.2 million) for the three months ended September 30, 2024. The increase is driven by costs associated with early commercial activities supporting the planned market launch of anzu-cel (IMA203). Net Profit and Loss: Net loss was $59.3 million1 (€50.5 million) for the three months ended September 30, 2025, compared to a net loss of $6.2 million1 (€5.3 million) for the three months ended September 30, 2024. The increase mainly resulted from lower revenue recognized from previous collaboration agreements and higher costs associated with the advancement of the product candidates in clinical trials.
