Oilfield services firm Transocean has acquired peer Valaris in an all-stock deal valued at US$5.8 billion, creating the world’s highest-specification offshore drilling fleet and one of the largest global offshore contractors.
Under the terms of the transaction. Valaris shareholders will receive 15.235 Transocean shares for each common share of Valaris.
Upon closing, Transocean shareholders will own approximately 53 per cent of the combined company, with Valaris shareholders owning the remaining 47 per cent.
The transaction is expected to close in the second half of 2026, subject to regulatory approvals.
The combined company will have an implied enterprise value of US$17 billion and a pro-forma market capitalisation of US$12.3 billion.
The merger brings together two complementary, premium offshore assets. The merged company will own 73 rigs, including 33 ultra-deepwater drillships, nine semisubmersibles and 31 modern jackups, to meet emerging growth opportunities.
Keelan Adamson, Transocean CEO said: “This transaction creates a very attractive investment in the offshore drilling industry, differentiated by the best fleet, proven people, leading technologies, and unequalled customer service.
“The powerful combination is well-timed to capitalise on an emerging, multi-year offshore drilling upcycle.
“Investors and our global customers will benefit from our expanded fleet of best-in-class, high-specification rigs.”
The merger is expected to unlock more than US$200 million in annual cost synergies, in addition to Transocean’s ongoing cost savings initiative, which is expected to reduce costs by more than US$250 million through 2026.
Valaris CEO Anton Dibowitz said: “By combining with Transocean, we will create a new industry leader for the benefit of our shareholders, customers and employees.
“We look forward to complementing Transocean’s high-specification deepwater assets with our own, while returning world class jackup expertise to Transocean’s business, creating a combined company that is capable of operating any rig at any water depth in any offshore environment around the world.”
Wood Mackenzie analysts view the merger as a significant step toward market consolidation in the offshore drilling sector.
Leslie Cook, Principal Analyst, Upstream Supply Chain for Wood Mackenzie, said the merger will solidify Transocean’s leading market position in the high-spec ultra-deepwater rig market.
“We are in a highly consolidated market with little room for organic growth. As a result, we did expect to see more consolidation this year and acquiring new backlog makes sense for Transocean,” Cook said.
The merger will also create increased financial flexibility for Transocean, allowing it to more efficiently capitalise on offshore upcycles.
“We have been signalling that the Upstream sector is continuing to consolidate,” said Cook.
“This deal further supports our bullish view on M&A as a strategic growth lever for offshore rig companies.”
