Houston, Texas and Tuebingen, Germany, May 12, 2026 – Immatics N.V. (NASDAQ:IMTX, "Immatics" or the "Company")), the global leader in precision targeting of PRAME with multiple clinical-stage programs spanning cell therapies and bispecifics, today provided a business update and reported financial results for the quarter ended March 31, 2026.

"Immatics is entering a pivotal period as we continue to progress toward the pre-specified interim and final analyses from the Phase 3 SUPRAME trial of anzu-cel and actively prepare for commercialization in 2027," said Harpreet Singh, Ph.D., Chief Executive Officer and Co-Founder of Immatics. "At the same time, we expect multiple meaningful clinical readouts across our PRAME franchise in 2026 that continue to validate PRAME as an important target across multiple solid cancers, extending well beyond melanoma, and across two different therapeutic modalities. Immatics today is a company defined not only by compelling science, but by a diversified late- and mid-stage clinical portfolio, growing commercial readiness, and a clear strategy to translate innovation into meaningful patient impact."

First Quarter 2026 and Subsequent Company Progress

PRAME Franchise – Cell Therapy

Anzu-cel (IMA203) PRAME Cell Therapy – First Market Entry in Advanced Melanoma

Anzu-cel (anzutresgene autoleucel), previously called IMA203, is Immatics' lead PRAME cell therapy and is expected to 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) advanced cutaneous melanoma, as well as metastatic uveal melanoma includes ~9,000 patients².

Anzu-cel received Orphan Drug Designation and RMAT designation³ from the U.S. Food and Drug Administration (FDA) for the treatment of both cutaneous and uveal melanoma.
Secondary analyses of Phase 1b clinical data on anzu-cel in advanced cutaneous and uveal melanoma will be presented during the Oral Abstract Session - Melanoma/Skin Cancers at the 2026 ASCO Annual Meeting, with a focus on characterizing response dynamics.

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 PD-1 immune checkpoint inhibitor.
SUPRAME is designed to be an adequate and well-controlled clinical trial intended to generate data to support regulatory approval of anzu-cel.
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 measuring quality of life.
Pre-specified interim and final data analyses are expected to be triggered in 2026 upon the occurrence of a defined number of events for PFS (progressive disease or death).
The Company continues to expect BLA submission in the first half of 2027 and commercial launch of anzu-cel in the second half of 2027.
Patient recruitment is currently ongoing in North America and Europe.

Phase 2 cohort for anzu-cel (IMA203) PRAME cell therapy in patients with metastatic uveal melanoma

A Phase 2 cohort to treat approximately 30 additional metastatic uveal melanoma patients is ongoing and being conducted at select centers in the U.S. and Germany with expertise in uveal melanoma.
Data from the ongoing single-arm Phase 1b trial as well as the Phase 2 cohort in metastatic uveal melanoma are intended to support a potential label expansion for anzu-cel following expected initial approval in cutaneous melanoma.

IMA203CD8 PRAME Cell Therapy (GEN2) – Expansion to all Advanced PRAME Cancers

IMA203CD8 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 (ovarian and uterine).

Updated Phase 1a dose-escalation and Phase 1b dose-expansion data in gynecologic cancers at clinically relevant dose levels will be presented during the Rapid Oral Abstract Session – Gynecological Cancer at the 2026 ASCO Annual Meeting.
The Company is on track to complete Phase 1a dose escalation and determine the recommended Phase 2 dose (RP2D) in 2026.

Further Updates on PRAME Cell Therapies

PRAME cell therapy beyond melanoma and gynecologic cancers: updated Phase 1 data on PRAME cell therapies (anzu-cel or IMA203CD8 GEN2) in synovial sarcoma, further demonstrating the potential to address diverse tumor types beyond melanoma and gynecologic cancers, will be presented during the Rapid Oral Abstract Session - Sarcoma at the 2026 ASCO Annual Meeting.
PRAME cell therapy using Immatics' TCR in a pediatric patient with cancer: a late-breaking poster on a PRAME-directed TCR T-cell therapy using Immatics' PRAME TCR administered under named-patient use in a heavily pretreated pediatric patient with extensive, multifocal nephroblastoma was presented at AACR Annual Meeting 2026. PRAME is expressed across multiple pediatric cancers, and these findings highlight the therapeutic potential of PRAME cell therapy in pediatric patients with solid tumors.

PRAME Franchise - Bispecifics

IMA402 PRAME Bispecific – Expansion to Earlier-Line PRAME Cancers

To expand our 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 PRAME bispecific with IMA401 MAGEA4/8 bispecific in squamous non-small cell lung cancer (sqNSCLC) and potentially other solid tumor indications.

IMA402 PRAME bispecific showed clinical proof-of-concept during the Phase 1a dose escalation trial in heavily pre-treated patients with solid tumors, including melanoma and ovarian cancer.
Immatics expects to determine the final RP2D and present a clinical data update from a larger patient population, with an initial focus on melanoma and gynecologic cancers treated with IMA402 monotherapy or combination with an immune checkpoint inhibitor, in the second half of 2026. As part of its strategy to maximize the IMA402 opportunity, the Company is in the process of opening additional Phase 1b cohorts in mid-2026 across both earlier and later treatment lines.
Based on the initial promising activity of IMA401 in head and neck cancer and sqNSCLC, Immatics believes it is uniquely 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. The Phase 1 trial evaluating the combination of IMA401/IMA402 in sqNSCLC is expected to commence mid-2026.

IMA401 MAGEA4/8 Bispecific – Maximizing the Potential of Bispecifics Combinations

Updated results for IMA401 targeting MAGEA4/8 across multiple cancers will be presented during the Developmental Therapeutics – Immunotherapy Oral Abstract Session at the 2026 ASCO Annual Meeting.
IMA401 clinical development will focus on a combination approach with the Company's PRAME bispecific, IMA402, to exploit synergistic potential and expanded patient reach.
The Phase 1 trial evaluating the combination of IMA401/IMA402 is expected to commence with sqNSCLC in mid-2026.

Corporate Development:

In collaboration, Moderna and Immatics developed a cancer antigen therapeutic candidate under the Database Program, incorporating targets identified using Immatics' XPRESIDENT® target discovery and validation platform and its bioinformatics and AI platform XCUBE®. The shared antigen therapeutic candidate owned by Moderna was submitted for IND, marking a key regulatory milestone under the Collaboration Agreement and triggering a milestone payment to Immatics.

First Quarter 2026 Financial Results

Cash Position: Cash and cash equivalents, as well as other financial assets, total $521.5 million¹ (€453.6 million) as of March 31, 2026, compared to $539.6 million¹(€469.3 million) as of December 31, 2025. The decrease is the result of ongoing research and development activities, partially offset by the net proceeds of an at-the-market offering of $24.4 million¹ net (€21.2 million) as well as changes in net working capital and foreign exchange rate differences.

Revenue: Total revenue, consisting of revenue from collaboration agreements, was $8.7 million¹(€7.6 million) for the three months ended March 31, 2026, compared to $21.4 million¹ (€18.6 million) for the three months ended March 31, 2025. The decrease is mainly due to a lower proportion of costs incurred relative to the overall project progress within the quarter.

Research and Development Expenses: R&D expenses were $68.1 million¹(€59.2 million) for the three months ended March 31, 2026, compared to $48.2 million¹(€41.9 million) for the three months ended March 31, 2025. The increase mainly resulted from costs associated with the advancement of the product candidates in clinical trials, particularly the SUPRAME clinical trial.

General and Administrative Expenses: G&A expenses were $16.7 million¹(€14.5 million) for the three months ended March 31, 2026, compared to $13.9 million¹(€12.1 million) for the three months ended March 31, 2025. 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 $66.5 million¹(€57.8 million) for the three months ended March 31, 2026, compared to a net profit of $45.9 million¹(€39.9 million) for the three months ended March 31, 2025. The decrease is driven by higher recognition of non-cash revenue in the three months ended March 31, 2025 compared to the three months ended March 31, 2026 and from higher costs associated with the planned advancement of the Company's PRAME franchise in clinical trials in the three months ended March 31, 2026.
