Saipem and Subsea7 removed a major U.S. condition for their planned merger after all applicable waiting periods under the Hart-Scott-Rodino antitrust law expired. The companies may now complete the transaction in the United States, but the announcement does not mean the cross-border merger itself has closed.
Regulatory approvals outside the United States remain outstanding. That distinction is material because the companies operate global fleets and engineering businesses serving offshore energy projects, and competition authorities in several markets can assess the effect of combining their vessel capacity, contracting expertise and customer relationships.
The transaction is structured as a merger of equals in which Subsea7 is merged into Saipem and the combined company is renamed Saipem7. Participating Subsea7 shareholders are to receive 6.688 new Saipem shares for each share, producing approximately equal ownership, and a €450 million extraordinary dividend is planned before the merger becomes effective.
Saipem7 is expected to remain incorporated in Italy, headquartered in Milan and listed in both Milan and Oslo. The dual-market structure preserves access to the shareholder bases of the two legacy companies while placing the operating group under a single corporate platform.
Management has projected about €21 billion of revenue, more than €2 billion of EBITDA and over €800 million of free cash flow for the combined business, based on historical pro forma figures. It has also identified a backlog of roughly €43 billion and annual run-rate synergies of €300 million; these are transaction forecasts, not guaranteed post-merger results.
The industrial case rests on complementary vessel fleets, technologies and geographic exposure across subsea engineering, construction and offshore services. A larger platform could bid for complex projects and allocate specialized assets across regions, but it also creates execution risk in fleet integration, project controls, workforce organization and the delivery of promised savings.
The U.S. milestone narrows one source of uncertainty without resolving the wider competition process. Expiry of a statutory waiting period is not the same as a global unconditional clearance, and the companies must still satisfy every remaining condition before shares, governance and operations can be combined.
Investors will now focus on the timetable and substance of the outstanding decisions. Until those approvals arrive and the legal merger becomes effective, Saipem and Subsea7 remain separate companies and Saipem7’s scale, synergies and financial targets remain forward-looking elements of the deal thesis.
