Black Diamond Therapeutics Reports First Quarter 2026 Financial Results and Provides Corporate Update

•Oral presentation of silevertinib Phase 2 data in frontline EGFRm NSCLC patients, including preliminary DOR and PFS data, to take place at the 2026 ASCO Annual Meeting

•First patient dosed in the Phase 2 trial of silevertinib in patients with newly diagnosed EGFRvIII+ GBM

•Cash, cash equivalents, and investments of $118.3 million as of March 31, 2026, expected to be sufficient to fund operations into 2H of 2028

CAMBRIDGE, MA, May 7, 2026 (GLOBE NEWSWIRE) – Black Diamond Therapeutics, Inc. (Nasdaq: BDTX), a clinical-stage oncology company developing MasterKey therapies that target families of oncogenic mutations in patients with cancer, today reported financial results for the first quarter ended March 31, 2026, and provided a corporate update.

“We remain focused on advancing silevertinib into pivotal development and are looking forward to the 2026 ASCO Annual Meeting later this month where an oral presentation of Phase 2 data will highlight silevertinib’s potential to benefit frontline EGFRm NSCLC patients,” said Mark Velleca, M.D., Ph.D., President and Chief Executive Officer of Black Diamond Therapeutics. “Our randomized Phase 2 trial in newly diagnosed EGFRvIII+ GBM also initiated this month with the dosing of our first patient.”

Recent Developments & Upcoming Milestones:

•In April 2026, Black Diamond announced the following presentations at the upcoming 2026 American Society of Clinical Oncology (ASCO) Annual Meeting from May 29 – June 2, 2026, in Chicago:

◦May 30, 2026, 1:15 PM-2:45 PM CDT: Oral presentation on updated clinical data from the Phase 2 trial in patients with non-classical EGFRm NSCLC in the frontline setting, including preliminary duration of response (DOR) and progression-free survival (PFS) data (Abstract: 8519).

◦May 31, 2026, 9:00 AM-12:00 PM CDT: Poster presentation on the Phase 2 data of silevertinib in recurrent EGFRm NSCLC patients (Abstract: 8620).

◦June 1, 2026, 1:30 PM-4:30 PM CDT: Trial-in-progress poster on the randomized Phase 2 trial of silevertinib in patients with newly diagnosed EGFRvIII-positive GBM (Abstract: TPS2098).

•In May 2026, the first patient was dosed with silevertinib in combination with temozolomide (TMZ) in the safety lead-in portion of the randomized Phase 2 trial in patients with newly diagnosed EGFRvIII+ GBM (NCT07326566).

Financial Highlights

•Cash Position: Black Diamond ended the first quarter of 2026 with approximately $118.3 million in cash, cash equivalents, and investments compared to $128.7 million as of December 31, 2025. Net cash used in operations was $10.2 million for the first quarter of 2026 compared to net cash provided by operations of $53.4 million for the first quarter of 2025.

•Research and Development Expenses: Research and development (R&D) expenses were $7.0 million for the first quarter of 2026, compared to $10.5 million for the same period in 2025. The decrease in R&D expenses was primarily due to the progression of our Phase 2 clinical trial for silevertinib in NSCLC and outlicensing of BDTX-4933 to increase focus on the development of silevertinib.

•General and Administrative Expenses: General and administrative (G&A) expenses were $4.3 million for the first quarter of 2026, compared to $5.0 million for the same period in 2025. The decrease in G&A expenses was primarily due to the realization of continued operational efficiencies.

•Net Loss: Net loss for the first quarter of 2026 was $9.0 million, as compared to net income of $56.5 million for the same period in 2025.

Financial Guidance

•Black Diamond ended the first quarter of 2026 with approximately $118.3 million in cash, cash equivalents and investments which the Company believes is sufficient to fund its anticipated operating expenses and capital expenditure requirements into the second half of 2028.
