Applicable risks and uncertainties include the risks and uncertainties, among other things, regarding: the success in the dev elo pment and potential commercialization of our product candidates, including avutometinib in combination with other compounds, including defactinib , LUMAKRAS and others; the uncertainties inherent in research and development, such as negative or unexpected results of clin ica l trials, the occurrence or timing of applications for our product candidates that may be filed with regulatory authorities in any jurisdictions; whether and when regulatory authorities in any jurisdictions may approve any such applicati ons that may be filed for our product candidates, and, if approved, whether our product candidates will be commercially successfu l in such jurisdictions; our ability to obtain, maintain and enforce patent and other intellectual property protection for our pro duc t candidates; the scope, timing, and outcome of any legal proceedings; decisions by regulatory authorities regarding trial de sig n, labeling and other matters that could affect the timing, availability or commercial potential of our product candidates; whet her preclinical testing of our product candidates and preliminary or interim data from clinical trials will be predictive of the re sults or success of ongoing or later clinical trials; that the timing, scope and rate of reimbursement for our product candidates is u nce rtain; that the market opportunities of our drug candidates are based on internal and third - party estimates which may prove to b e incorrect; that third - party payors (including government agencies) may not reimburse; that there may be competitive developments affecting our product candidates; that data may not be available when expected; that enrollment of clinical trials may take l on ger than expected, which may delay our development programs ;

The forward - looking statements in this presentation speak only as of the original date of this presentation, and we undertake n o obligation to update or revise any of these statements whether as a result of new information, future events or otherwise, except as required by law. Use of Non - GAAP Financial Measures This presentation contains references to our non - GAAP operating expense, a financial measure that is not calculated in accordanc e with generally accepted accounting principles in the US (GAAP). This non - GAAP financial measure excludes certain amounts or expenses from the corresponding financial measures determined in accordance with GAAP. Management believes this non - GAAP informa tion is useful for investors, taken in conjunction with the Company's GAAP financial statements, because it provides greater transparency and period - over - period comparability with respect to the Company's operating performance and can enhance in vestors' ability to identify operating trends in the Company's business. Management uses this measure, among other factors, to assess and analyze operational results and trends and to make financial and operational decisions. Non - GAAP information is no t prepared under a comprehensive set of accounting rules and should only be used to supplement an understanding of the Company's operating results as reported under GAAP, not in isolation or as a substitute for, or superior to, financial inform ati on prepared and presented in accordance with GAAP. In addition, this non - GAAP financial measure is unlikely to be comparable wit h non - GAAP information provided by other companies. The determination of the amounts that are excluded from non - GAAP financial mea sures is a matter of management judgment and depends upon, among other factors, the nature of the underlying expense or income amounts. Reconciliations between this non - GAAP financial measure and the most comparable GAAP financial measure are in cluded in the footnotes to the slides in this presentation on which such non - GAAP number appears. Third - Party Sources Certain information contained in this presentation, including industry and market data and other statistical information, rel ate s to or is based on studies, publications, surveys and other data obtained from third - party sources and the Company's own intern al estimates and research. While the Company believes these third - party sources to be reliable as of the date of this presentation, it has not independently verified, and makes no representation as to the adequacy, fairness, accuracy or completeness of, any information obtained from third - party sources. In addition, all of the market data included in this presentation involves a numb er of assumptions and limitations, and there can be no guarantee as to the accuracy or reliability of such assumptions Disclaimers

28 Adapted from Hofmann et al., Cancer Discovery 2022 • The only approved KRAS inhibitors target KRAS G12C, which is largely restricted to NSCLC • KRAS G12D accounts for 26% of all KRAS mutations • KRAS G12D mutations are especially prevalent in pancreatic and colorectal cancers • Targeting KRAS G12D has historically been challenging due to the shallow pocket for drug interaction and lack of a cysteine for covalent binding KRAS G12D is the Most Frequent KRAS Mutation in Human Cancers
