(WO) – Halliburton has appointed veteran oil and gas executive Timothy A. Leach to its board of directors, effective Dec. 2, 2025, adding one of the U.S. shale sector’s most recognizable leaders to the company’s governance team. Leach will stand for election at Halliburton’s 2026 annual shareholders meeting.
Leach retired earlier this year after a 40-year career that included senior leadership roles at ConocoPhillips and, notably, his long tenure as chairman and CEO of Concho Resources, which he led from its formation in 2006 through its 2021 acquisition by ConocoPhillips. He later served as ConocoPhillips’ executive vice president for the Lower 48 before taking on an advisory role to the CEO.
Halliburton Chairman, President and CEO Jeff Miller said Leach’s experience across U.S. unconventionals, strategic planning and corporate governance will support the company’s long-term goals. “Tim is a widely respected leader in the oil and gas business,” Miller said. “He brings decades of upstream experience—from building startups to guiding large independent operators. His expertise will be invaluable as Halliburton continues to engineer solutions that maximize asset value for our customers.”
Leach holds a petroleum engineering degree from Texas A&M University and an MBA from the University of Texas of the Permian Basin. He continues to serve on ConocoPhillips’ board and remains active in several regional and industry organizations, including the Permian Strategic Partnership, MD Anderson Cancer Center Board of Visitors and the Caesar Kleberg Wildlife Research Institute advisory board.
