ConocoPhillips has appointed Andy O'Brien as president and chief executive officer, elevating the company's finance chief to the top job in a planned succession that the Houston-based energy producer announced on 6 August 2026. O'Brien assumes the role on 1 September 2026 and joins the board of directors.
O'Brien had served as executive vice president and chief financial officer, with responsibility for strategy and commercial activity. He joined the predecessor company, Conoco, in 1997 and has spent nearly three decades across finance, planning, strategy and international operations, including the group's liquefied natural gas business.
Ryan Lance, who led ConocoPhillips as chairman and chief executive for 14 years, moves to the role of executive chairman in a transitional capacity, preserving continuity as the new leadership settles in. The orderly handover reflects a board that has prepared for the change over an extended period rather than reacting to a sudden departure.
The reshuffle extends to the finance function. Konnie Haynes-Welsh, previously vice president of finance and controller, has been promoted to senior vice president and chief financial officer, stepping into the seat O'Brien vacates.
ConocoPhillips is one of the largest independent exploration and production companies in the world, with operations spanning North America, Europe, Asia Pacific and the Middle East. The company has expanded significantly in recent years, including its enlarged position in the Permian Basin and its growing LNG portfolio, moves that have increased the demand on senior leadership to combine operational discipline with commercial ambition.
The appointment fits a wider pattern across the energy sector and corporate America, where finance chiefs are increasingly winning the chief executive role. A background in capital allocation, portfolio strategy and disciplined spending has become prized at a moment when oil and gas producers are balancing shareholder returns against the cost of sustaining production and funding lower carbon investment. O'Brien's LNG and international experience is particularly relevant as the company continues to build out its global gas positions.
For investors, the transition signals continuity rather than a change of direction. Lance's move to executive chairman keeps institutional knowledge close to the boardroom during the first year of the new tenure, while O'Brien's long internal record lowers the execution risk that often accompanies a leadership change at a company of this scale. The elevation of Haynes-Welsh from within the finance organisation reinforces the message that the company is promoting a tested internal bench rather than importing outside leadership.
Lance oversaw a period in which ConocoPhillips reshaped itself around low cost, high return assets and returned substantial capital to shareholders. Handing the chief executive role to the architect of much of that financial and commercial strategy suggests the board wants the next phase to build on the same framework. O'Brien inherits a balance sheet and a portfolio widely regarded as among the strongest in the sector, along with the expectation that he will sustain returns discipline through the commodity cycle.
