Effective January 6, 2025, the Board of Directors of 2seventy bio, Inc. (the “Company”) appointed Jessica Snow to the position of Chief Operating Officer.

Ms. Snow previously served as the Company’s SVP of Quality from November 2021 to April 2024 and held Quality leadership roles at bluebird bio from 2018 to October 2021.

There are no arrangements or understandings between Ms. Snow and any other persons pursuant to which she was appointed as an executive officer of the Company.
