Halliburton Company (NYSE: HAL), a global leader in energy services, has appointed Timothy A. Leach to its board of directors, effective December 2, 2025.
The move expands the board to 12 members, with Leach slated for shareholder election at the 2026 annual meeting.
Announced on December 2 amid steady oil market conditions, the appointment underscores Halliburton’s focus on upstream expertise as it navigates demand for innovative drilling solutions.
Halliburton Chairman, President, and CEO Jeff Miller praised the addition, stating: “On behalf of the board, I am pleased to welcome Tim to Halliburton.
“Tim is a widely respected leader in the oil and gas business.
“He brings decades of leadership in the oil and gas industry and deep expertise in upstream operations, strategic planning, and corporate governance.”
Miller noted that Leach’s extensive experience managing oil and gas ventures from startups to major enterprises, along with steering their expansion, will prove essential.
This expertise supports Halliburton’s core commitment to partnering with clients, developing innovative solutions that optimise asset performance, and generating sustained value for shareholders.
Leach retired in August 2025 from ConocoPhillips after a 40-year career, where he served on the board, as executive vice president for Lower 48 operations, and as advisor to the CEO.
Previously, he chaired and led Concho Resources Inc. from its 2006 founding until its US$13.3 billion all-stock acquisition by ConocoPhillips in January 2021, growing it into a Permian Basin powerhouse with over 550,000 net acres.
His earlier roles included executive positions at Concho Oil & Gas Corp. and Parker & Parsley, sharpening his skills in shale development and operational scaling.
