Messrs. Ford and Lamouche will serve until the 2026 Annual Meeting of Stockholders and thereafter until their respective successors are duly elected and qualified. Each of Messrs. Ford and Lamouche will participate in the Company’s standard non-employeedirector compensation arrangements.

For a director to be considered independent, the Board must determine that the director does not have any direct or indirect material relationship with the Company.

In accordance with these guidelines, the Board has determined that each of Messrs. Ford and Lamouche are independent. Neither Mr. Ford nor Mr. Lamouche is a party to any transaction, or series of transactions, required to be disclosed pursuant to Item 404(a) of Regulation S-K.
