Chevron Corporation has named seasoned business leader Thomas W. Horton as an independent member of its board, the U.S. energy company announced Tuesday. Horton’s appointment takes effect immediately and also includes a seat on Chevron’s audit committee.

Horton, 64, brings a wide range of corporate leadership and governance experience to the boardroom. He is currently a partner at Global Infrastructure Partners, a firm focused on global infrastructure investment, and has previously held roles advising private-equity firm Warburg Pincus. Before moving into investment and advisory work, Horton led American Airlines—serving as its chairman, president and chief executive officer. He also held senior leadership positions at companies such as AT&T Corporation earlier in his career.

In addition to his executive background, Horton has been a board director for major corporations, including Walmart and General Electric Company (now GE Aerospace), giving him broad exposure to governance across different industries.

Chevron’s CEO, Mike Wirth, has said he is in discussions with the board about the timing of his departure from the company, a topic of interest for investors and industry watchers as Chevron navigates changes in its leadership and strategy.

Horton’s appointment comes as the company looks to strengthen oversight of financial reporting and governance, with his audit committee role underscoring that focus.
