Exxon and CNOOC Ltd (0883.HK), opens new tab filed arbitration claims claiming a pre-emption right to any sale of Hess’ lucrative stake in a Guyana oil-producing joint venture. The challenge threatens to block Chevron’s biggest deal since its 2001 acquisition of Texaco for $36 billion.
Exxon and CNOOC have argued Chevron's bid for Hess triggered a right of first refusal clause in their Guyana joint operating agreement. Chevron and Hess dispute that claim.
The all-stock sale, announced last October, has been stalled by a second request for information by antitrust regulator, the U.S. Federal Trade Commission. Its review should be completed this quarter, a spokesman for Hess said.
