Saipem and Subsea7 merger faces EU Phase 2 test as €300m synergy case hangs on remedies

Saipem S.p.A. and Subsea7 S.A. are approaching another critical regulatory milestone in their planned merger after the European Commission’s Phase 2 antitrust review was paused in August while additional information was supplied. Subsea7 Chief Executive Officer Stuart Fitzgerald said on September 16 that the companies expected the Commission to clarify the next step shortly, potentially reopening the formal review timetable. The transaction would create Saipem7, a global offshore and energy-services group with roughly €20 billion of revenue, more than €2 billion of EBITDA and a combined backlog of around €43 billion based on the companies’ original transaction metrics. Saipem and Subsea7 shareholders are expected to own 50% each of the combined company, with Subsea7 investors receiving 6.688 new Saipem shares for every Subsea7 share held. The central tension is whether the industrial logic of combining two major offshore engineering platforms can survive European competition scrutiny without remedies that erode the €300 million of annual synergies expected from the merger.

Why has the European Commission moved the Saipem and Subsea7 merger into a Phase 2 investigation?

The European Commission opened a Phase 2 investigation in July after concluding that the proposed combination raised serious doubts about compatibility with the European Union’s internal market. A Phase 2 review is not a finding that the merger should be blocked, but it signals that the Commission believes a deeper investigation is required before it can determine whether competition would remain sufficient in the affected markets.

The review focuses on offshore engineering and construction activities, where both companies provide complex services across subsea infrastructure, field development and related energy projects. These markets can be concentrated because only a limited number of contractors possess the specialised vessels, engineering capacity, technical expertise and financial strength required to execute large offshore projects. A transaction that combines two of those operators therefore attracts greater scrutiny than a merger involving companies active in more fragmented service markets.

The Commission suspended the timetable on August 25 after seeking additional information from the parties. Saipem and Subsea7 have since submitted further material, and the immediate question is when the formal clock resumes and whether the Commission identifies specific competitive concerns requiring remedies. That timing matters because the companies originally targeted completion during the second half of 2026.

How is the Saipem and Subsea7 merger structured and who will control Saipem7?

The transaction is structured as a cross-border merger in which Subsea7 will merge into Saipem and the combined company will operate under the Saipem7 name. Subsea7 shareholders will receive 6.688 new Saipem shares for each Subsea7 share they hold, resulting in existing Saipem and Subsea7 shareholders each owning approximately 50% of the enlarged group.

Subsea7 shareholders are also entitled to an extraordinary dividend of €450 million immediately before completion. The companies previously authorised ordinary shareholder distributions ahead of the merger as long as agreed financial conditions were met, allowing both groups to continue returning capital while regulatory approvals were being pursued.

The combined company will remain incorporated in Italy and headquartered in Milan, while its shares are expected to trade in both Milan and Oslo. Reference shareholders Siem Industries, Eni and CDP Equity have supported the transaction, giving management a relatively stable ownership base as the regulatory process continues.

The structure is closer to a merger of equals than a conventional takeover. That matters because the integration challenge extends beyond buying and absorbing a smaller competitor. Saipem7 would need to combine two sizeable engineering organisations, vessel fleets, project-management systems and corporate cultures while preserving customer relationships across several continents.

Why do Saipem and Subsea7 believe a larger offshore engineering platform creates strategic value?

The strongest industrial argument is scale. Offshore developments are becoming larger, more technically complex and more capital intensive, particularly in deepwater oil and gas, subsea tiebacks and offshore energy infrastructure. Contractors capable of offering engineering, procurement, construction, installation and long-term project support can compete for larger project packages and potentially reduce interfaces for customers.

Saipem brings broad offshore and onshore engineering capabilities, drilling assets and a substantial presence across the Mediterranean, Middle East and other global markets. Subsea7 contributes a strong subsea engineering franchise, specialised vessel fleet and established relationships with major offshore operators. Combining those capabilities could allow Saipem7 to bid for projects that would otherwise require partnerships between several contractors.

Geographic diversification is another part of the rationale. The combined backlog was expected to have no single country contributing more than 15%, reducing dependence on any one national market. That diversification can improve revenue visibility, although it also increases exposure to different regulatory systems, labour markets and geopolitical conditions.

How important are the projected €300 million annual synergies to the merger economics?

Saipem and Subsea7 expect approximately €300 million of annual run-rate synergies by the third year after completion, with one-time implementation costs of around €270 million. Those savings are expected to come from overlapping corporate functions, procurement, vessel utilisation, operational coordination and broader cost efficiencies across the combined organisation.

The synergy target is strategically important because a 50-50 merger does not create value merely by increasing reported revenue and backlog. Shareholders need evidence that the combined company can generate higher margins, stronger free cash flow and better returns than the two businesses could have produced independently.

Vessel utilisation may be particularly significant. Offshore construction vessels are expensive assets, and profitability improves when fleets spend more time on productive work and less time repositioning or waiting between projects. A larger project portfolio can potentially allow management to allocate specialised vessels more efficiently across regions and customer programmes.

Regulatory remedies could reduce those benefits if the Commission requires assets, contracts or business units to be divested. The final value of the transaction therefore depends not only on securing approval but also on the conditions attached to that approval.

Why could the European Commission be concerned about competition in offshore engineering services?

Large subsea engineering projects are not markets where customers can easily replace one supplier with dozens of alternatives. Contractors need specialised ships, engineering teams, project-management capability and experience managing technical and safety risks across complex offshore environments. The number of credible bidders can therefore be limited on the largest projects.

A combined Saipem7 would have one of the industry’s broadest offshore fleets and engineering organisations. That scale can benefit customers through integrated execution and stronger financial capacity, but it can also reduce the number of independent contractors competing for specific categories of work. The Commission must determine whether customers would retain enough alternatives to preserve competitive pricing and innovation.

The regulatory analysis may differ by project type rather than treating offshore engineering as one market. Competition for subsea umbilicals, risers and flowlines can differ from competition in heavy lifting, conventional offshore construction, drilling or onshore engineering. Any remedies are therefore likely to depend on where the Commission identifies the strongest overlaps.

How would the merger change the competitive landscape for TechnipFMC and other offshore contractors?

A completed Saipem7 combination would create a larger rival to companies including TechnipFMC, Baker Hughes-linked subsea operations and other offshore engineering contractors. Greater scale could improve Saipem7’s ability to compete for integrated contracts covering engineering, subsea equipment installation and broader field development.

Customers could benefit from a larger contractor with more balance-sheet capacity to execute multi-billion-euro projects. Offshore developments can run for several years and expose contractors to engineering changes, weather disruption and cost inflation, making financial resilience an important selection criterion.

Competitors may respond by investing in fleets, forming alliances or pursuing acquisitions of specialised engineering and marine-services businesses. The merger could therefore contribute to wider consolidation across offshore services, particularly as energy companies sanction larger developments and demand greater execution certainty from contractors.

What do Saipem and Subsea7 share prices suggest while the regulatory process remains unresolved?

Subsea7 shares closed at NOK319.20 in Oslo on September 15, up about 2.7% during the session. The stock was approximately 2.5% lower than its September 9 close and around 8.2% below the August 17 level, while remaining within a 52-week range of roughly NOK180.10 to NOK358.20.

Saipem shares closed at €4.222 in Milan on September 15, gaining approximately 1.6% for the session. The shares were about 3.6% below the September 9 close and approximately 7.3% below the August 17 level, within a 52-week range of roughly €2.166 to €4.846.

The recent weakness in both stocks cannot be attributed solely to merger regulation because offshore energy shares have also been influenced by oil prices, project expectations and broader market volatility. However, regulatory timing has become increasingly relevant because investors originally expected completion during the second half of 2026.

The next Commission communication will therefore matter because it can reduce or extend uncertainty around the closing timetable. A reopened review with a defined deadline would at least restore visibility, while prolonged information requests or significant remedy discussions could push completion further out.

What would happen if the European Commission requires remedies before clearing Saipem7?

Remedies could take several forms depending on the Commission’s findings. The companies could offer to divest selected assets, contracts or activities where competition concerns are concentrated, or provide behavioural commitments designed to preserve customer access and competitive conditions.

The economic impact would depend on what is surrendered. Selling a peripheral asset may have little effect on the merger rationale, while divesting strategically important vessels or business units could reduce revenue, backlog and expected synergies. Investors would therefore need to evaluate clearance conditions rather than assuming that any approval produces the same transaction economics.

A more severe outcome would involve substantial structural remedies that make the 50-50 combination less attractive than originally planned. The companies would then need to decide whether the strategic benefits still justify completion. Nothing in the current process establishes that such an outcome will occur, but the Phase 2 review makes the quality of any eventual clearance as important as the fact of clearance itself.

What milestones will determine whether the Saipem and Subsea7 merger remains on track?

The immediate milestone is confirmation that the European Commission has resumed the Phase 2 review and publication of an updated decision timetable. That will determine whether completion can still occur close to the companies’ intended schedule or whether the merger moves further into the future.

The next issue is the scope of any remedy discussions. If regulators accept the companies’ arguments without requiring material asset sales, the original €300 million synergy case remains more intact. A significant remedy package would require investors to revisit the combined earnings and backlog assumptions.

Operational performance remains important while the process continues. Both companies need to protect project execution, margins and customer relationships during a prolonged pre-merger period. The strategic case strengthens if strong standalone results combine with regulatory progress and a clean integration plan. It weakens if delays extend materially, key assets must be sold or uncertainty begins to affect contract awards and management attention.
