DOJ clears Transocean and Valaris merger after antitrust review

Transocean Ltd. and Valaris Limited received notice on September 30, 2026, that the U.S. Department of Justice Antitrust Division has concluded its review of their proposed merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976. The expiration of the statutory waiting period removes a key regulatory hurdle for the offshore drilling companies.

The two firms originally signed a Business Combination Agreement on February 9, 2026. Under the terms of that deal, Transocean will acquire all outstanding Valaris common shares in exchange for 15.235 Transocean shares for each Valaris share. This structure represents a major consolidation within the offshore energy services sector.

With the antitrust investigation now closed, Transocean and Valaris anticipate completing the business combination in the fourth quarter of 2026. This timeline remains conditional on meeting or waiving the other closing requirements specified in the agreement. The companies disclosed this regulatory milestone in a Form 8-K filed with the U.S. Securities and Exchange Commission.

The filing includes standard cautionary language regarding forward-looking statements associated with the proposed transaction. Management notes that various risks and uncertainties persist, which could cause actual results to differ from current expectations. These factors include potential litigation, operational disruptions during the pendency of the deal, and challenges in retaining key personnel and customers.

The companies also highlight risks related to integrating Valaris operations into Transocean without unexpected costs or delays. There is no assurance that anticipated synergies will be realized on the expected timeline or at all. The filing further notes that certain counterparties may hold rights to terminate or amend contracts upon a change of control, which could impact business performance during the transition.
