Transocean Acquires Valaris for $5.8 Billion

Transocean Ltd. has signed a definitive agreement to acquire Valaris Limited in an all-stock transaction valued at approximately $5.8 billion. This merger will combine two of the industry's most modern offshore rig fleets, creating a global operator with an estimated enterprise value of $17 billion and a market capitalization of $12.3 billion. Valaris shareholders will receive 15.235 shares of Transocean for each Valaris share, resulting in Transocean shareholders owning approximately 53% and Valaris shareholders 47% of the combined company. The merged entity will operate a fleet of 73 rigs, including ultra-deepwater drillships, semisubmersibles, and modern jackups, expanding its reach across major offshore basins. Transocean expects to achieve over $200 million in cost synergies, in addition to existing cost-reduction programs. The transaction, unanimously approved by both boards, is expected to close in the second half of 2026, subject to regulatory and shareholder approvals. Keelan Adamson will lead the combined company as CEO, with Jeremy Thigpen serving as Executive Chairman.
