Inc., Icahn Enterprises Holdings L.P., IPH GP LLC, Icahn Capital LP, Icahn Onshore LP, Icahn Offshore LP and Beckton Corp (collectively, the “Icahn Group”) and Andrew J. Teno.

Pursuant to the Board Observer Agreement, Andrew J. Teno shall have the right to serve as a non-voting observer to the Board of Directors of the Company (the “Board”).

Pursuant to the Board Observer Agreement, the Icahn Group has agreed to certain customary standstill and mutual non-disparagement restrictions. The Board Observer Agreement may be terminated by either the Company or the Icahn Group at any time upon notice to the other party.

Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year

On December 2, 2025, the Board approved, effective July 1, 2026, a reduction in the number of active committees of the Board from seven to five by (i) eliminating the Finance Committee and distributing its responsibilities and duties between the full Board and the Audit Committee, and (ii) combining the Nominating and Governance Committee and the Human Resources Committee, and renaming the combined committee the Nomination, Governance & Compensation Committee.
