ConocoPhillips CFO O'Brien to Become CEO as Lance Retires

ConocoPhillips CFO Andy O'Brien will take over as president and chief executive on Sept. 1, succeeding Ryan Lance, who is retiring from the top role after 14 years. Lance will become executive chair of the board.

The announcement came alongside a second-quarter profit of $3.9 billion, up from $2 billion a year earlier, boosted by high oil prices. ConocoPhillips, the largest independent U.S. oil and gas producer by market cap at about $140 billion, spun off from Phillips 66 in 2012, when Lance became CEO.

O'Brien joined ConocoPhillips in 1997 as a financial analyst in England. Over nearly three decades he has held more than a dozen roles across finance, strategy, and operations, including controller in Alaska and senior vice president of global operations. He has been on the executive leadership team since 2022.

"All of this is a strong recipe for a successful CFO-to-CEO transition," said Scott Simmons, co-managing partner at executive search firm Crist Kolder Associates. Simmons noted O'Brien's experience outside finance, including global operations and commercial roles, built credibility with the board on intangibles such as leadership ability and investor relationships.

Crist Kolder reported that 10.26% of sitting CEOs at Fortune 500 and S&P 500 firms in 2025 came directly from the CFO role, up from 7.1% in 2024 and 6.5% in 2015. The trend is continuing in 2026, with O'Brien the latest example.

Konnie Haynes-Welsh, currently vice president of finance and controller, was promoted to senior vice president and CFO. She has nearly 15 years at ConocoPhillips, holding roles from manager of SEC compliance to chief accounting officer to vice president and treasurer.

The leadership change comes at a time of strong financial performance but also geopolitical risk. The Iran war has kept oil prices elevated, boosting profits. ConocoPhillips carries an Alpha Score of 56, rated Moderate, reflecting its stable but not high-growth profile. Its stock page is /stocks/cop.

The transition appears orderly, with O'Brien having been groomed for the role. The board's decision to promote an insider with deep operational and financial experience suggests continuity in strategy. Lance's move to executive chair provides a bridge.

What would undermine the transition is a sharp drop in oil prices or an operational misstep. What would reinforce it is continued strong cash flow and successful execution of the company's capital return program. The next quarterly earnings in October will offer the first look under O'Brien's leadership.
