Ms. Moore’s current term as a director is scheduled to expire on the date of the Annual Meeting. Ms. Moore’s decision to retire and not stand for re-election is not a result of any disagreement with ONEOK, including on any matter relating to its operation, policies or practices. ONEOK also announced on March 25, 2026, that Gerald B. Smith will not be standing for re-election to the Board due to the Company’s mandatory age retirement policy, which provides that a director will retire from the Board no later than immediately prior to the annual meeting of shareholders following a director’s 75th birthday. Mr. Smith’s current term is scheduled to expire on the date of the Annual Meeting. Mr. Smith’s decision to retire and not stand for re-election is not a result of any disagreement with ONEOK, including on any matter relating to its operation, policies or practices.
