Immatics N.V.

Phase 1a dose escalation is complete. Immatics is currently enrolling patients with uterine cancer at clinically relevant doses to further expand the clinical dataset in this indication. In addition, a Phase 1/2 investigator-initiated trial (“IIT”) in patients with PRAME-positive pediatric cancers is planned to start in 1H 2027. The clinical activity of IMA203CD8 observed across tumor types with distinct biology and differing levels of PRAME expression, including ovarian cancer, uterine cancer, melanoma and synovial sarcoma, supports the broad applicability of IMA203CD8 across PRAME-positive cancers. The development approach for IMA203CD8 will leverage targeted cohorts of selected tumor types, such as ovarian cancer, uterine cancer, rare cancers and pediatric cancers to build the clinical evidence base for broader, tumor-agnostic application.

Certain statements in this report may be considered forward-looking statements. Forward-looking statements generally relate to future events or the Company’s future financial or operating performance. For example, statements concerning timing of data read-outs for product candidates, the timing, outcome and design of clinical trials, the nature of clinical trials (including whether such clinical trials will be registration-enabling), the timing and outcomes of IND, CTA, BLA and other regulatory filings, or the timing of commercial launches, estimated market opportunities of product candidates, manufacturing timetables, capacity and success rates, the potential benefits of product candidates, the Company’s focus on partnerships to advance its intended strategy, and other metrics are forward-looking statements. In some cases, you can identify forward-looking statements by terminology such as “may”, “should”, “expect”, “plan”, “target”, “intend”, “will”, “estimate”, “anticipate”, “believe”, “predict”, “potential” or “continue”, or the negatives of these terms or variations of them or similar terminology. Such forward-looking statements are subject to risks, uncertainties, and other factors which could cause actual results to differ materially from those expressed or implied by such forward-looking statements. These forward-looking statements are based upon estimates and assumptions that, while considered reasonable by Immatics and its management, are inherently uncertain. New risks and uncertainties may emerge from time to time, and it is not possible to predict all risks and uncertainties. Factors that may cause actual results to differ materially from current expectations include, but are not limited to, various factors beyond management's control including general economic conditions and other risks, uncertainties and factors set forth in the Company’s Annual Report on Form 20-F and other filings with the Securities and Exchange Commission (SEC). Nothing in this report should be regarded as a representation by any person that the forward-looking statements set forth herein will be achieved or that any of the contemplated results of such forward-looking statements will be achieved. You should not place undue reliance on forward-looking statements, which speak only as of the date they are made. The Company undertakes no duty to update these forward-looking statements. All the scientific and clinical data presented within this report are – by definition prior to completion of the clinical trial and a clinical study report – preliminary in nature and subject to further quality checks including customary source data verification.

In connection with the foregoing, the Company made available a presentation, a copy of which is attached hereto as Exhibit 99.1.
