Chevron Triumphs Over Exxon, Wins 20-Month Battle to Buy Hess

Chevron Corp. has prevailed in a 20-month fight to buy Hess Corp. for $53 billion, overcoming a challenge by arch rival Exxon Mobil Corp. that was unprecedented in the modern history of Big Oil.

The ruling by an arbitration court allowing the deal to close is a major victory for Chevron, ending a period of strategic limbo that hurt its stock and prompted questions over the quality of the company’s due diligence when it agreed to buy Hess in October 2023. Chevron Chief Executive Officer Mike Wirth said he would walk away from the deal if they lost the case.
