Shift4 Payments said Executive Chairman Jared Isaacman resigned from the board after being sworn in as NASA Administrator on December 18, 2025, and Taylor Lauber was appointed Chairman. Isaacman's agreement with the U.S. Office of Government Ethics also calls for him to vote about 25% of his affiliated voting power under a letter agreement, and he plans to collapse the company's Up-C structure within 60 days, which would end the company's status as a controlled company under NYSE rules.
