MBX Biosciences appoints Steve Hoerter as chairperson

In November 2025, the Company’s board of directors appointed Steve Hoerter to serve as executive chairperson, to support the Company’s executive team with his perspective and commercialization experience, as the Company prepares for the start of a Phase 3 trial and begins pre-commercial activities. Mr. Hoerter joined the Company’s board of directors earlier this year, bringing more than 30 years of pharmaceutical commercialization and executive leadership experience, most recently as President and Chief Executive Officer of Deciphera Pharmaceuticals until its $2.4 billion acquisition by Ono Pharmaceutical in 2024. Jim Cornelius also retired from the board as of October 31, 2025, after more than five years of valuable service.
