Transocean commits US$5.8Bn to acquire rival Valaris

Two of the world’s largest offshore drilling rig companies are set to join fleets in an all-stock deal that would see Transocean acquire Valaris.

Both of the companies have confirmed the signing of a definitive agreement to combine in an acquisition that is valued at US$5.8Bn.

When the deal is complete, Transocean will hold a marginal controlling share of the company of 53%, with Valaris retaining 47% of the combined company share.

The deal will create a fleet totalling 73 rigs, including 33 ultra-deepwater drill ships, nine semi-submersibles and 31 jack-up rigs. 

According to the two companies, the acquisition transaction "implies a combined enterprise value of approximately US$17.0Bn". The deal is expected to close in the second half of 2026, following the necessary approvals from regulators and shareholders. 

The newly merged Transocean entity’s senior management team will be led by chief executive Keelan Adamson, and Jeremy Thigpen will serve as executive chairman of the board. The board will be comprised of nine current Transocean directors and two current Valaris directors. Transocean will remain incorporated in Switzerland, with its primary administrative office in Houston, Texas, in the US. Both companies have significant administrative offices in Houston, with Valaris incorporated in Bermuda.

In terms of fleet structures, Valaris, the target of the acquisition by Transocean, has by far the larger of the two fleets of rigs, with a heavy majority being jack-ups. The company’s current rig roster, published on its website, shows 13 drill ships, two semi-submersibles, two managed platforms and 34 jack-up rigs.

Valaris chief executive Anton Dibowitz said, “We look forward to complementing Transocean’s high-specification deepwater assets with our own, while returning world-class jack-up 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.”

Transocean, by comparison, lists a fleet of 27 rigs, 20 ultra-deepwater rigs capable of working in water depths between 3,048-3,658 m, and seven harsh environment rigs.

Transocean president and chief executive Keelan Adamson said, “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. We have identified more than US$200M in cost synergies that will complement our ongoing efforts to safely lower costs." 

While the prediction of an emerging, multi-year upcycle does not guarantee continued favourable conditions for rig owners, M3 Marine Group chief executive Mike Meade told Riviera that "oil and gas is not going away". 

"Positive signs are emerging in several regions that will generate demand for OSVs and rigs. Saudi Aramco is calling back previously suspended jack-ups for work in the Middle East, and FPSO projects in West Africa," Mr Meade noted. Mr Meade’s outlook for 2026 can be described as bullish. “At some point between the middle of the year and the third quarter, it’s going to take off because there is not enough supply and demand is increasing.”

Transocean cited a US$10.0Bn contract backlog for its fleet and highlighted an ongoing cost-reduction effort that aims to cut more than US$250M in costs through the end of 2026, among the positive financial elements of its current and future positioning.

Commenting on the deal for Transocean to acquire Valaris, Wood Mackenzie Principal Analyst Leslie Cook said the move would allow Transocean to "solidify their market-leading position in the high spec ultra-deepwater rig market and become a top-five player in the high spec jack-up 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," Ms Cook said. "As the market moves closer to the duopoly conditions that other supply chain sectors exhibit, rig owners will gain pricing power. Short-term this supports prices. Longer-term, it positions Transocean to more efficiently capitalise on offshore upcycles."

In Westwood Global Energy Group’s most recent tally of offshore drilling operators, Valaris was the second-largest operator, behind China Oilfield Services’ 65-rig fleet, while Transocean’s 36 rigs put the company in sixth place.
