**PRESS RELEASE**

**Whitehawk Therapeutics Reports Third Quarter 2025 Financial Results and Recent Highlights**

MORRISTOWN, NJ, November 6, 2025 /PRNewswire/ -- Whitehawk Therapeutics, Inc. (Nasdaq: WHWK), an oncology therapeutics company applying advanced technologies to established tumor biology to efficiently deliver improved antibody drug conjugate (ADC) cancer treatments, today announced financial results for the third quarter ended September 30, 2025, and provided recent corporate progress.

"The third quarter was marked by executional focus, and we remain on track with our planned IND filings for HWK-007 and HWK-016 by the end of the year. We continue to deploy capital efficiently, maintaining strong financial discipline as we prepare to enter the clinic and deliver potentially value-creating milestones," said Dave Lennon, PhD, President and CEO of Whitehawk Therapeutics. "I'm proud of our role in adding to the scientific understanding of PTK7 with the data we presented at AACR-NCI-EORTC. Confirming PTK7 as the third most highly expressed tumor marker among clinically validated and emerging ADC targets, these data underscore the tremendous opportunity we have with our first ADC candidate, HWK-007, to make a difference for the nearly 750,000 patients in the US with PTK7-expressing cancers."

**Recent Operational Highlights:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Presented real-world analysis at AACR-NCI-EORTC** confirming PTK7 as a broadly expressed, clinically relevant target across solid tumors. The analysis was part of a collaboration between Whitehawk and Tempus AI.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**On track to bring all three assets to IND by mid-2026.** IND submissions are planned by year-end 2025 for HWK-007 and HWK-016. An IND for HWK-206 is expected by mid-2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•**Focused execution and capital efficiency support anticipated runway into 2028.** Based on current plans, cash position enables initial clinical data readouts across the portfolio.

**Third Quarter 2025 Financial Results:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Cash, cash equivalents and short-term investments as of September 30, 2025, were $162.6 million as compared to $47.2 million as of December 31, 2024. Cash is anticipated to fund operations into 2028 based on current plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Net loss for the three months ended September 30, 2025, was $17.7 million as compared to $12.5 million for the three months ended September 30, 2024.
