## Questions

### What is BridgeBio Oncology Therapeutics' relationship to BridgeBio Pharma?

It operates as a majority-owned subsidiary within BridgeBio Pharma's decentralized R&D structure. This hub-and-spoke model lets the oncology team focus exclusively on its pipeline while relying on the parent for shared services like regulatory affairs, toxicology, and financial controls. BridgeBio Pharma has used similar structures for other programs, including its cardiorenal and gene therapy affiliates.

### Which specific cancer targets does the firm's pipeline address?

The pipeline centers on tumors driven by mutations in KRAS, including a G12C dual inhibitor designed to combat resistance and a pan-KRAS program targeting active GTP-bound KRAS across multiple mutation types. A third program inhibits PI3Kα, a lipid kinase frequently mutated in breast and other solid tumors, with a design that spares normal PI3K activity to limit side effects.

### How does the firm fund its drug development work?

In March 2024, BridgeBio Pharma announced a deal to sell a partial equity stake in the oncology subsidiary to a consortium of life sciences investors. This external financing round was structured to provide dedicated capital for oncology programs while BridgeBio retained majority ownership. The transaction echoes maneuvers the parent has used to fund other subsidiaries, creating separate capital pools for distinct therapeutic areas.

### Who chairs BridgeBio Oncology Therapeutics?

Frank McCormick, a molecular biologist who co-led the team that established the mechanistic link between RAS mutations and human cancer at Cetus Corporation in the 1980s, serves as chairman. He currently holds the David A. Wood Chair of Tumor Biology at the UCSF Helen Diller Family Comprehensive Cancer Center and previously directed the university's cancer center.

### Does the firm operate as a venture-stage asset manager or a drug developer?

It is a clinical-stage drug developer, not an investment vehicle. All capital — whether from the parent balance sheet or external investors — funds internal drug programs advancing toward IND filings and clinical trials. It does not make fund commitments, co-investments, or secondary market purchases.
