Chevron announced its roughly $53 billion Hess acquisition with total confidence in October 2023, then spent 13 months stuck in a legal fight with ExxonMobil and CNOOC over a right-of-first-refusal clause it had no control over — before winning arbitration in July 2025 and closing a deal management says "has only gotten better" since it was announced.
The story
October 2023: total confidence
Chevron announced it would acquire Hess Corporation in an all-stock deal worth about $53 billion — including Hess's stake in the giant Stabroek block offshore Guyana. On the Q3 2023 call, management said it expected to close "in the first half of 2024." The Q4 2023 call went further: the company was "excited about the pending Hess acquisition."
An unexpected snag
The problem came from an unexpected direction. Hess's Stabroek operating agreement carried a right-of-first-refusal clause, and existing partners ExxonMobil and China's CNOOC claimed they had the right to buy first. What the FY2023 10-K described as "discussions" escalated, by the FY2024 10-K, into "arbitration" — and the closing target kept slipping. On the Q2 2024 call, CEO Michael Wirth himself called this stretch "this period of limbo around Hess," admitting it would take longer than expected. By Q3 2024, an analyst directly challenged management: "hasn't the Hess uncertainty effectively erased Hess's value" from the stock? The CEO defended the deal — "we're confident this will conclude successfully" — but the market wasn't fully convinced.
Holding the line
Chevron's response was to hold steady rather than change its story. Buybacks were restricted under SEC rules while the deal was pending, but the company kept buying Hess stock on the open market instead — about 5% of Hess by Q1 2025 — continuing to bet on the deal closing. The FY2024 10-K gave the first concrete timeline: an arbitration hearing scheduled for May 2025, with a decision expected roughly three months later.
The reversal
In August 2025, the wait ended. Chevron won the arbitration and closed the Hess merger, and analysts congratulated the win on the same call. The FY2025 10-K doesn't mention "arbitration" a single time — once the risk resolved, it was quietly removed from the risk-factor list entirely, replaced with the completed-tense line: Chevron had secured its 30% Stabroek stake.
Guidance scorecard
| Promise | Actual result | Result |
|---|---|---|
| Hess acquisition close — "first half of 2024" (Q4 FY2023 call) | Closed Jul 18, 2025 (13-month delay) | Missed |
| Hess shareholder vote — "late May" (Q1 FY2024 call) | Approved May 28, 2024 | Met |
| Arbitration decision — "hearing May, decision ~3 months later" (FY2024 10-K) | Won and closed Jul 18 (~2.5 months after hearing) | Largely met |
| 2025 structural cost savings — "$1.5-2B annualized" (Q2 FY2025 call) | $1.5B realized, $2B annualized run-rate reached | Met |
| Buyback pace — "~$17.5B annual" (Q1 FY2024 call) | Actual 2024 buybacks $15.0B (restricted-period impact) | Partially met |
| 2025 production growth — "ex-Hess, upper end of 6-8%" (Q2 FY2025 call) | Reached the upper end, ex-Hess (Q4 FY2025 call) | Met |
| Dividend — consecutive annual increases | 38 consecutive years through 2025 | Fully met |
5 of 7 fully met, 1 largely met, 1 clearly missed. The one clear miss — acquisition closing timing — was the single promise genuinely outside Chevron's control. Everything the company could directly execute (cost savings, dividends, shareholder votes) was kept almost without exception.

Our read
The clearest lesson from these 21 months is the importance of separating what a company controls from what it doesn't. Chevron's execution on everything within its own authority — cost savings, shareholder votes, dividend continuity — was essentially flawless. The one genuine miss, the acquisition's closing timeline, was hostage to a third-party arbitration process Chevron had no ability to accelerate. Separately, walking back the 2050 net-zero target in the same filing suggests the company's priorities are shifting toward near-term execution over long-term climate commitments.
What we still don't know
- Exactly how much incremental free cash flow the Guyana and Bakken (Hess) assets will generate over the coming years isn't confirmable without a full FY2026 fiscal year behind it.
- Whether Chevron will introduce a new long-term climate target to replace the walked-back 2050 net-zero goal isn't knowable from this data — the next Investor Day or FY2026 10-K would clarify.
- Whether the 21% year-over-year drop in 2025 buybacks is a temporary, debt-driven pause or a new capital-allocation pattern needs another quarter or two to confirm.
Frequently asked questions
Why was the Chevron-Hess deal stuck in arbitration?
ExxonMobil and CNOOC argued a right-of-first-refusal clause in an existing joint venture with Hess gave them a say over the roughly $53 billion Chevron-Hess deal — a dispute Chevron had no control over and that took 13 months to resolve.
Did Chevron win the Hess arbitration?
Yes — Chevron won arbitration in July 2025 and closed the deal, with management saying it "has only gotten better" since it was originally announced in October 2023.
