Forward - Looking Statements . Certain statements in this presentation 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 clinical trial application for IMA 204 , IMA 301 , IMA 401 , the Company’s focus on partnerships to advance its strategy, projections of future cash on hand and other metrics are forward - looking statements . In some cases, you can identify forward - looking statements by terminology such as “may”, “should”, “expect”, “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 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 filings with the Securities and Exchange Commission (SEC) . Nothing in this presentation 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 .

In addition, all of the market data included in this presentation involves a number of assumptions and limitations, and there can be no guarantee as to the accuracy or reliability of such assumptions . Finally, while the Company believes its internal research is reliable, such research has not been verified by any independent source . Clinical study results and associated biomarker studies presented within this presentation are by definition prior to completion of the clinical trial and a clinical study report and, are therefore, preliminary in nature and subject to further quality checks including customary source data verification . This meeting and any information communicated at this meeting are strictly confidential and should not be discussed outside your organization .
