Chevron Corporation emerged victorious in its high-stakes arbitration battle with Exxon Mobil, finally clearing the path for its $53 billion acquisition of Hess Corp. The decision ends more than 20 months of legal limbo that has weighed on both companies’ stock prices and strategic planning.

The arbitration victory represents a major win for Chevron CEO Mike Wirth, who had publicly stated he would walk away from the deal if the company lost the case. The uncertainty surrounding the acquisition had been a “material contributor” to Chevron’s stock underperformance compared to its rivals, according to Wirth’s November comments.
Hess shares jumped as much as 8.8% in pre-market trading following the announcement, while Chevron stock rose 3.9%. The market reaction reflects investor relief that the long-delayed deal can finally proceed without further legal challenges.
Strategic Value of Guyana Assets
The acquisition centers on Hess’s 30% stake in Guyana’s offshore Stabroek Block, one of the world’s most prolific oil discoveries in recent years. Exxon operates the block and owns a 45% stake, making it a direct competitor to Chevron in the region.
Fernando Valle from Hedgeye Risk Management called the Guyana assets “critical for Chevron” because the company’s growth portfolio outside the Permian Basin was previously limited. The deal helps narrow the gap between Chevron and Exxon in terms of high-quality oil assets.
The legal dispute arose from Exxon’s claim that it had a right of first refusal over any disposition of Hess’s Guyana stake. However, Chevron and Hess successfully argued that this right didn’t apply because their transaction was structured as a corporate merger rather than an asset sale.
The clash between North America’s biggest energy producers was unprecedented in the modern history of Big Oil. Companies in this industry typically partner with each other to minimize project risk and share costs, making the public legal battle unusual.
Both sides had expressed extreme confidence in their legal positions throughout the process. Exxon CEO Darren Woods said in December that his company “wrote these documents” and understood their intent, giving them confidence in their position.
Regulatory Approval and Board Changes
The Federal Trade Commission added another layer of complexity to the deal by initially barring John Hess from joining Chevron’s board. The FTC had accused him of colluding with OPEC, but dropped this order on Thursday.
A Chevron spokesman welcomed the regulatory change, stating that “Mr. Hess is a highly respected industry leader, and our board would benefit from his global experience, relationships and expertise.”
The deal’s completion will benefit arbitrage traders who bet on the spread between Hess’s share price and the exchange ratio agreed with Chevron. Major hedge funds including Millennium Management, Pentwater Capital Management and HBK Investments had staked billions of dollars on the deal closing.
Chevron’s stock has shown recent strength, with shares closing at $151.38, up 0.97% for the day. After-hours trading saw the stock rise to $157.20, reflecting a 3.84% gain above the closing value.
The company’s market capitalization stands at approximately $264.37 billion, with a trailing twelve-month dividend yield of 4.41%. Chevron has been expanding into lower-carbon energy projects, including a proposed blue ammonia plant in Texas.
Chevron will announce its Q2 2025 earnings on August 1, which may provide additional insights into the company’s performance and strategic outlook following the arbitration victory.
