• Advanced enrollment in the pivotal Phase 3 OPERA-02 trial and the Phase 1 study of OP-3136 as a monotherapy and in combination with fulvestrant and palazestrant in ER+/HER2- MBC. Anticipated Upcoming Events • Initiate enrollment in the Phase 1b/2 study evaluating OP-3136 in combination with darolutamide in mCRPC in collaboration with Bayer in the fourth quarter of 2026. • Report top-line data from the pivotal Phase 3 OPERA-01 trial in the first quarter of 2027. Second Quarter 2026 Financial Results Cash, cash equivalents, and marketable securities as of June 30, 2026, were $461.1 million. Net loss for the quarter ended June 30, 2026 was $63.2 million, as compared to $43.8 million for the quarter ended June 30, 2025. The increase in net loss for the second quarter was related to higher spending on clinical development and research and corporate-related activities related to late-stage clinical trials for palazestrant and the advancement of OP-3136. GAAP research and development (R&D) expenses were $57.8 million for the quarter ended June 30, 2026, as compared to $43.9 million for the quarter ended June 30, 2025. The increase in R&D expenses was primarily related to increased spending on clinical development-related activities as we continue to advance palazestrant through late-stage clinical trials and OP-3136 in early-stage clinical studies, and increased personnel-related costs to support expanding development activities, including an increase in non-cash stock-based compensation expense of $5.2 million, mainly due to higher grant prices in 2026 and higher headcount. These increases were partially offset by the $10.0 million milestone expense related to the Aurigene agreement that was recognized in the same period in 2025. Non-GAAP R&D expenses were $48.9 million for the quarter ended June 30, 2026, excluding $8.9 million non- cash stock-based compensation expense. Non-GAAP R&D expenses were $40.2 million for the quarter ended June 30, 2025, excluding $3.7 million non-cash stock-based compensation expense. A reconciliation of GAAP to non-GAAP financial measures used in this press release can be found at the end of this press release. GAAP G&A expenses were $9.4 million for the quarter ended June 30, 2026, as compared to $4.0 million for the quarter ended June 30, 2025. The increase in G&A expenses was primarily due to higher corporate-related costs that reflect continued investment in personnel and corporate infrastructure to support our expanding late-stage clinical development activities and anticipated future commercial operations, including an increase in non-cash stock-based compensation expense of $3.0 million, mainly due to higher grant prices in 2026, and an increase in professional fees of $1.8 million. Non-GAAP G&A expenses were $5.4 million for the quarter ended June 30, 2026, excluding $4.0 million non-cash stock-based compensation expense. Non-GAAP G&A expenses were $3.0 million for the quarter ended June 30, 2025, excluding $1.0 million non-cash stock-based compensation expense. A reconciliation of GAAP to non- GAAP financial measures used in this press release can be found at the end of this press release.

receptors, and mechanisms of acquired resistance. Our lead product candidate, palazestrant (OP-1250), is a proprietary, orally available complete estrogen receptor antagonist (CERAN) and a selective estrogen receptor degrader (SERD), currently in two Phase 3 clinical trials. In addition, Olema is developing OP-3136, a potent lysine acetyltransferase 6 (KAT6) inhibitor, now in a Phase 1 clinical study. Olema is headquartered in San Francisco and has operations in Cambridge, Massachusetts. For more information, please visit www.olema.com. About Palazestrant (OP-1250) Palazestrant (OP-1250) is a novel, orally available small molecule with dual activity as both a complete estrogen receptor antagonist (CERAN) and selective estrogen receptor degrader (SERD). It is currently being investigated in patients with recurrent, locally advanced or metastatic ER-positive (ER+), human epidermal growth factor receptor 2-negative (HER2-) breast cancer. In clinical studies, palazestrant completely blocks ER-driven transcriptional activity in both wild-type and mutant forms of metastatic ER+ breast cancer and has demonstrated anti-tumor efficacy along with attractive pharmacokinetics and exposure, favorable tolerability, central nervous system penetration, and combinability with cyclin-dependent kinase 4/6 (CDK4/6) inhibitors. Palazestrant has been granted U.S. Food and Drug Administration (FDA) Fast Track designation for the treatment of ER+/HER2- metastatic breast cancer that has progressed following one or more lines of endocrine therapy with at least one line given in combination with a CDK4/6 inhibitor. It is being evaluated as a single agent in the ongoing pivotal Phase 3 clinical trial, OPERA-01, and in combination with ribociclib in the ongoing pivotal Phase 3 clinical trial, OPERA-02. Palazestrant is also being evaluated in multiple Phase 1/2 studies in combination with ribociclib, palbociclib, alpelisib, everolimus, and atirmociclib. About OP-3136 OP-3136 is a novel, orally available small molecule that potently and selectively inhibits lysine acetyltransferase 6 (KAT6), an epigenetic target that is dysregulated in breast and other cancers. In preclinical studies, OP-3136 has demonstrated significant anti-proliferative activity in ER+ breast cancer models and is combinable and synergistic with endocrine therapies including palazestrant and cyclin-dependent kinase 4/6 (CDK4/6) inhibitors. The Investigational New Drug (IND) application for OP-3136 was cleared by the U.S. Food and Drug Administration (FDA) in December 2024 and patients are currently enrolling in the Phase 1 clinical study. Non-GAAP Financial Information The results presented in this press release include both GAAP information and non-GAAP information. As used in this release, non-GAAP R&D expense is defined by Olema as GAAP R&D expense excluding stock-based compensation expense, and non-GAAP G&A expense is defined by Olema as GAAP G&A expense excluding stock-based compensation expense. We use these non-GAAP financial measures to evaluate our ongoing operations and for internal planning and forecasting purposes. We believe that non-GAAP financial information, when taken collectively, may be helpful to investors because it provides consistency and comparability with past financial performance. However, non-GAAP financial information is presented for supplemental informational purposes only, has limitations as an analytical tool, and should not be considered in isolation or as a substitute for financial information presented in accordance with GAAP. Other companies, including companies in our industry, may calculate similarly titled non-GAAP measures differently or may use other measures to evaluate their performance, all of which could reduce the usefulness of our non-GAAP financial measures as tools for comparison. Investors are encouraged to review the related GAAP financial measures and the reconciliation of these non-GAAP financial measures to their most directly comparable GAAP financial measures and not rely on any single financial measure to evaluate our business.
