As previously disclosed, Fidji Simo, Chair of the Board of Directors (the “Board”) of Maplebear Inc. (the “Company”) continued to serve as Chair following her resignation as Chief Executive Officer and President of the Company in order to ensure a smooth transition. Following the completion of the transition, on November 21, 2025, Ms. Simo informed the Company of her decision to resign as Chair and as a member of the Board, effective immediately upon the appointment by the Board of a new Chair. Ms. Simo’s resignation is not due to any disagreement with the Company or any matter relating to the Company’s operations, policies, or practices.

On November 24, 2025, the Board appointed Chris Rogers to succeed Ms. Simo as Chair. In connection with Ms. Simo’s resignation, the size of the Board was reduced from ten directors to nine directors.

“I’m incredibly grateful to have served as Chair of Instacart’s Board of Directors, and am stepping down following Chris Rogers’ successful transition to CEO. The Company’s momentum is clear, and it’s operating from a position of strength thanks to the leadership of Chris and his outstanding management team. As Instacart executes against its strategy, there’s tremendous opportunity for the Company to help redefine what’s possible across the grocery industry in partnership with its retail and brand partners,” said Fidji Simo, Chief Executive Officer, Applications, OpenAI.
