(“PMV Pharma” or the “Company”; Nasdaq: PMVP), a precision oncology company pioneering the discovery and development of small molecule therapies targeting p53, today reported financial results for the third quarter ended September 30, 2025, and provided a corporate update. “I am incredibly proud of our team and their commitment to rapidly and efficiently advancing the PYNNACLE study,” said David Mack, Ph.D., President and Chief Executive Officer of PMV Pharma. “We are excited by the data emerging from this study and look forward to submitting an NDA in the first quarter of 2027 for platinum- resistant/refractory ovarian cancer.” Corporate Highlights • Updated clinical results from the Phase 2 pivotal portion of the PYNNACLE study evaluating rezatapopt were featured in late-breaking oral and poster presentations at the 2025 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics on October 24, 2025. o Confirmed responses were observed in patients whose tumors were TP53 Y220C mutated and KRAS wild-type in eight tumor types including ovarian, lung, breast, endometrial, head and neck, colorectal, gallbladder cancers, and ampullary carcinoma. o Overall response rate (ORR) of 34% (35/103 patients) per investigator assessment according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, including confirmed and unconfirmed responses. The cohort-specific ORRs were as follows: § Ovarian cancer: 46% ORR (22/48 patients, including one confirmed complete response, 18 confirmed partial responses, and three unconfirmed partial responses [uPR]) § Breast cancer: 17% ORR (2/12 patients) § Endometrial cancer: 60% ORR (3/5 patients, including one uPR) § Lung cancer: 21% ORR (4/19 patients, including one uPR) § Other solid tumors: 21% ORR (4/19 patients) o Across all cohorts, the median time to response was 1.3 months and the median duration of response was 7.6 months. In the ovarian cancer cohort, the median

time to response was 1.3 months and median duration of response was 8.0 months. o Post the September 4, 2025 data cutoff date, four uPRs were confirmed and one uPR (ovarian cancer) remains on treatment. o A poster entitled “Natural history and prognostic value of TP53 Y220C mutation in advanced solid tumors: A real-world study,” was also presented at the 2025 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics which concluded that patients with TP53 Y220C-mutated solid tumors had poor prognoses and reduced overall survival compared to patients without a TP53 Y220C mutation. Third Quarter 2025 Financial Results PMV Pharma ended the third quarter with $129.3 million in cash, cash equivalents, and marketable securities, compared to $148.3 million as of June 30, 2025. Net cash used in operations was $56.4 million for the nine months ended September 30, 2025, compared to $34.6 million for the nine months ended September 30, 2024. • Net loss for the quarter ended September 30, 2025, was $21.1 million compared to $19.2 million for the quarter ended September 30, 2024. The net loss increase was primarily due to increased research and development (R&D) costs. • R&D expenses were $18.2 million for the quarter ended September 30, 2025, compared to $16.9 million for the quarter ended September 30, 2024. The increase in R&D expenses was primarily due to increased contractual research organization costs for the advancement of the rezatapopt program. • General and administrative (G&A) expenses were $4.3 million for the quarter ended September 30, 2025, compared to $4.9 million for the quarter ended September 30, 2024. The decrease in G&A expenses was primarily due to reduced spend for stock-based compensation and facility and operational expenses. About Rezatapopt Rezatapopt (PC14586) is a first-in-class, small molecule, p53 reactivator designed to selectively bind to the pocket in the p53 Y220C mutant protein, restoring the wild-type tumor-suppressor function. The U.S. Food and Drug Administration granted Fast Track designation to rezatapopt for the treatment of patients with locally advanced or metastatic solid tumors with a p53 Y220C mutation. About the PYNNACLE Clinical Trial The ongoing Phase 1/2 PYNNACLE clinical trial is evaluating rezatapopt in patients with advanced solid tumors harboring a TP53 Y220C mutation. The primary objective of the Phase 1 portion of the clinical trial was to determine the maximum tolerated dose and recommended Phase 2 dose (RP2D) of rezatapopt when administered orally to patients. Safety, tolerability, pharmacokinetics and effects on biomarkers were also assessed. The Phase 2 portion is a registrational, single arm, expansion basket clinical trial comprising five cohorts (ovarian, lung, breast, and endometrial cancers, and other solid tumors) with the primary objective of evaluating the efficacy of rezatapopt at the RP2D in patients with TP53 Y220C and KRAS wild-type advanced solid tumors. For more information about the Phase 1/2 PYNNACLE clinical trial, refer to www.clinicaltrials.gov (NCT trial identifier NCT04585750).
