Saipem, Subsea7 clear US antitrust hurdle as Saipem7 merger heads for H2 2026 close

Saipem S.p.A. (BIT: SPM) and Subsea 7 S.A. (OSE: SUBC) confirmed on Jul 31, 2026 that all applicable waiting periods under the U.S. Hart-Scott-Rodino Antitrust Improvements Act have expired for the proposed cross-border merger that would create Saipem7, an offshore engineering and construction group with approximately €21 billion of pro-forma revenue, more than €2 billion of adjusted EBITDA and a €43 billion combined backlog. The clearance permits the parties to close the transaction in the United States, though Saipem stressed the merger remains subject to certain regulatory approvals outside the U.S. The announcement lifts one of the more procedurally sensitive antitrust gates but leaves the two decisive reviews, the European Commission’s Phase II investigation and Australia’s in-depth review, unresolved. The central tension for investors is that the machinery of the deal is on track, with 8 of the 16 antitrust authorities that must scrutinise the combination now having cleared it per Alessandro Puliti’s Jul 28 remarks, yet the second-half 2026 closing timeline still turns on Brussels and Canberra rather than Washington.

What did the U.S. Hart-Scott-Rodino clearance actually resolve for the proposed Saipem-Subsea7 merger and what does it leave unresolved

The Hart-Scott-Rodino Antitrust Improvements Act of 1976 requires parties to a large merger notifiable in the United States to observe a statutory waiting period during which the Federal Trade Commission and the Department of Justice review the transaction. The expiration of that waiting period without action means neither U.S. authority has decided to challenge the combination or to impose remedies as a condition of its progress in the United States. For a transaction of Saipem’s and Subsea7’s scale, particularly one involving global offshore engineering, procurement, construction and installation services with United States customer exposure, that is a meaningful procedural step. It removes one credible source of last-minute execution risk from the closing timetable.

However, Hart-Scott-Rodino clearance does not amount to the merger being cleared. Saipem’s own statement made the scope explicit: the transaction remains subject to certain regulatory approvals outside the United States. What that carve-out actually covers is far more consequential. The European Commission moved the transaction into a Phase II investigation around Jul 22, 2026, having concluded that its initial review left material competition questions unresolved. The Australian Competition and Consumer Commission also opened its own in-depth probe. Both reviews are focused on similar concerns: whether combining two of the largest global providers of offshore engineering, subsea installation and related energy services would concentrate pricing power in offshore oil, gas and offshore wind markets. Investors treating Jul 31 as a signal that the deal is nearly done should read the Saipem announcement more literally. The remaining approvals are the ones that decide whether Saipem7 becomes a listed entity in the second half of 2026 or slips into 2027.

How does the Saipem7 combination reshape the offshore engineering and construction landscape at a €21 billion revenue base

The proposed transaction has been unusually explicit about the pro-forma economics of the combined company from the start. Saipem and Subsea7 signed a memorandum of understanding in February 2025 and a binding merger agreement on Jul 24, 2025. Under the terms of that agreement, Subsea 7 S.A. would be merged into Saipem through an EU cross-border statutory process, with the enlarged company renamed Saipem7. It would remain incorporated in Italy, would be headquartered in Milan and would list its shares on both the Milan and Oslo stock exchanges. Subsea7 shareholders participating in the combination would receive 6.688 new Saipem shares for each Subsea7 share they hold, resulting in Saipem and Subsea7 shareholders each owning approximately 50 percent of Saipem7. Immediately prior to completion, Subsea7 would distribute an extraordinary cash dividend of €450 million to its shareholders, alongside a further €105 million dividend tied to a permitted business divestment.

The industrial profile of the combined group is what the deal was designed to deliver. Saipem7 would have combined revenue of approximately €21 billion, adjusted EBITDA in excess of €2 billion, free cash flow of more than €800 million and a backlog of around €43 billion, with no single country contributing more than 15 percent of that backlog. The Offshore Engineering and Construction business, retaining the Subsea7 brand and to be headquartered in London, would consolidate all of Subsea7’s activities together with Saipem’s Asset-Based Services business. Around 83 percent of the combined group’s trailing 12-month EBITDA sits in that Offshore E&C unit. The remaining three businesses, Onshore E&C, Sustainable Infrastructures and Offshore Drilling, would sit alongside it. Management identified annual run-rate synergies of approximately €300 million and reference shareholders Siem Industries, Eni and CDP Equity would together hold roughly 28.9 percent of the combined equity, with Siem Industries the largest single holder at about 11.9 percent.

Why do the European Commission’s Phase II probe and the Australian in-depth review now dominate the near-term timeline for closing

The Phase II designation is significant because it signals the European Commission has not been satisfied that the transaction can be cleared unconditionally on the initial review timetable. In practice, Phase II adds a further statutory review window and typically ends either with an unconditional decision, a decision conditional on remedies such as asset divestitures, or a prohibition. The concerns that led Brussels to escalate are aligned with those raised by opposing oil majors in earlier jurisdictions: whether a combined Saipem and Subsea7 would meaningfully reduce competition in offshore subsea construction, engineering and offshore installation services, and whether the resulting concentration would leave key customers with too few credible bidders on large offshore projects.

Brazil’s antitrust authority CADE cleared the transaction unconditionally on Jun 23, 2026, an outcome that was itself notable given that Exxon Mobil, Petrobras and TotalEnergies had filed formally against the combination on customer-concentration grounds. That approval remains subject to appeal by opposing parties. Australia’s in-depth review runs in parallel with the European process and is grounded in similar concerns about competition in offshore energy services. Puliti told analysts on the Jul 28 Saipem earnings call that in-depth probes were “perfectly understandable” given the scale of the transaction and the business. The neutral read on that comment is that management continues to guide to a second-half 2026 close but is preparing the ground for the possibility that closing conditions in one or more jurisdictions may require carefully calibrated commitments. Saipem and Subsea7 have not publicly proposed remedies, and both companies continue to describe the timeline as second half of 2026 subject to regulatory approvals.

What does the 6.688 exchange ratio and the €450 million Subsea7 extraordinary dividend imply for pro-forma shareholder value

The exchange ratio is fixed and the extraordinary dividends attach only to Subsea7 shareholders, which means the arithmetic of the deal has become progressively more sensitive to the underlying Saipem share price as the review process has extended. Saipem shares were trading in the €3.90 to €4.10 range on Borsa Italiana around the Jul 28 to Jul 31 window, with the stock closing at €3.977 on Jul 28 after the Q2 print, a same-session move of about minus 8.74 percent. The 52-week range on the Borsa Italiana listing runs from €2.166 to €4.846, with the €4.846 peak reached on Jun 15, 2026. Investing.com’s aggregated 12-month consensus price target of €5.00 across 13 buy and 1 sell ratings implies roughly 13.6 percent upside from prevailing levels, though such targets are subject to revision post-Q2. Subsea7 was trading around $305.40 on Oslo Børs into the Q2 print, near the upper end of its 52-week range of $180.50 to $358.40.

At a Saipem share price near €4, the 6.688 exchange ratio implies a stock consideration of approximately €26.75 per Subsea7 share before the €450 million extraordinary dividend. The dividend equates to a further several euros per Subsea7 share depending on precise share count timing. What that means in practice is that any material further re-rating of Saipem, positive or negative, before completion directly changes the value Subsea7 shareholders receive at close, while Saipem shareholders bear the corresponding dilution or accretion in reverse. The narrowing arbitrage between Subsea7’s Oslo price and the implied Saipem package indicates the market is now pricing the deal at high probability of completion but has not yet fully absorbed the timing risk introduced by the EU Phase II process.

How did the divergent Q2 2026 prints from Saipem and Subsea7 reshape the operating baseline heading into the merger close

The Q2 prints reported by the two companies in the week before the Hart-Scott-Rodino clearance were unusually divergent. Subsea7 reported Q2 2026 revenue of $1.9 billion, up 10 percent year on year, with adjusted EBITDA of $471 million, up 31 percent, and an adjusted EBITDA margin of 24.4 percent against 20.5 percent in the prior-year quarter. Order intake of $2.1 billion equated to a book-to-bill of 1.1 times in the quarter and 0.9 times in the first half. Backlog stood at $13.6 billion, including $3.9 billion scheduled for execution in 2026 and $5.6 billion for 2027. Management raised its full-year adjusted EBITDA margin guidance to approximately 24 percent from around 23 percent. Subsea7 shares held above $305 into the print.

Saipem’s H1 2026 print was more mixed. First-half revenue rose 1.9 percent year on year to €7.35 billion, with adjusted EBITDA up 9.4 percent to €836 million and adjusted net profit of €131 million. Free cash flow after lease repayments reached €388 million, and net cash pre-IFRS 16 stood at €1.08 billion. Q2 revenue rose 3.4 percent to €3.82 billion, though Q2 adjusted EBITDA slipped 2.7 percent to €402 million and Q2 net income fell to €18 million from €63 million in the year-ago quarter. Order intake of €5.7 billion in H1, plus a further €2.3 billion in July, lifted backlog to €29.9 billion at Jun 30. Management absorbed roughly €70 million of costs in H1 tied to Middle East logistics and safety measures and assumed a similar drag in H2, prompting a downward revision of full-year adjusted EBITDA guidance to €1.75 billion. Saipem shares fell about 8.74 percent on Jul 28.

The practical read for Saipem7 is that Subsea7 enters the merger with visibly stronger operating momentum than the Saipem stand-alone base, particularly on offshore margin. Given that around 83 percent of Saipem7’s trailing 12-month EBITDA will sit inside the Subsea7-branded Offshore E&C unit, that operational asymmetry actually reinforces the industrial logic Puliti has argued from the start. It also raises the stakes for management on delivery of the €300 million of run-rate synergies.

Why does the Stuart Fitzgerald leadership transition at Subsea7 matter for offshore engineering execution inside Saipem7

Subsea 7 S.A. confirmed on Jul 1, 2026 that Stuart Fitzgerald had succeeded John Evans as chief executive of Subsea7 with effect from that date. Evans, who joined Subsea7 in its predecessor forms 40 years ago and had led the company since 2020, was proposed for continued service on the Subsea 7 S.A. board as a non-executive director. Fitzgerald previously ran Seaway7, the Subsea7 Group offshore wind installation business, from 2022 and has held senior commercial and strategy roles across the group since joining in 1998. He is also proposed as chief executive of the Subsea7 operating business inside Saipem7 upon completion of the merger. Alessandro Puliti remains chief executive of Saipem and is proposed as chief executive of Saipem7.

The transition timing matters. Fitzgerald’s stepping into the CEO seat at Subsea7 four weeks before the Hart-Scott-Rodino expiry means he has already begun to represent Subsea7 in the closing phase of the regulatory process, in Q2 results communication and in customer conversations that would carry into Saipem7 on day one. His stated Q2 remarks emphasised continuity of strategy in subsea and renewables while progressing toward the creation of a stronger global competitor in energy services. For institutional investors, the practical implication is that the operational leader who would run the largest earnings pool inside Saipem7 has now had a full quarter of engagement in the CEO chair before the deal actually closes, which reduces one strand of integration risk that would otherwise land on day one.

Where does the deal leave institutional expectations against the current Saipem share price and Subsea7 backlog visibility

For Saipem’s share price to be sustained above €4, and for a further move toward the €5 consensus target, three tests will have to be passed in reasonable sequence. The European Commission’s Phase II probe will need to conclude with either an unconditional clearance or a manageable remedies package that does not materially impair the combined Offshore E&C business or dilute the €300 million synergy target. The Australian in-depth review will need to run to a comparable outcome. And Saipem’s own H2 execution will need to arrest the trajectory implied by the €1.75 billion adjusted EBITDA guide, particularly on Middle East corridors where the €70 million disruption drag has now been assumed twice.

If Saipem7 does close in H2 2026, the pro-forma combined entity would enter 2027 with a backlog approaching €43 billion, more than €2 billion of adjusted EBITDA, more than €800 million of free cash flow, dual listing across Milan and Oslo, and a governance structure that puts operational leadership of the largest business inside London under Fitzgerald and group leadership under Puliti in Milan. The base case remains that the combination proceeds; the case for caution is that Brussels can still shape the terms.

What should investors track as Saipem, Subsea7 progress toward the Saipem7 close through the second half of 2026

• Saipem S.p.A. and Subsea 7 S.A. confirmed on Jul 31 2026 that all applicable waiting periods under the U.S. Hart-Scott-Rodino Antitrust Improvements Act had expired, permitting closing of the merger in the United States and lifting one procedural gate on the H2 2026 timetable.
• The transaction remains subject to certain regulatory approvals outside the U.S., with the European Commission’s Phase II investigation opened around Jul 22 2026 and Australia’s in-depth review the two most consequential outstanding gates for actual closing.
• Alessandro Puliti told analysts on the Jul 28 Saipem Q2 earnings call that 8 of the 16 antitrust authorities scrutinising the transaction have now cleared it, with in-depth probes on the remainder characterised by management as understandable given the scale of the business.
• Brazil’s antitrust authority CADE cleared the transaction unconditionally on Jun 23 2026 despite formal opposition filings from Exxon Mobil, Petrobras and TotalEnergies; that decision remains subject to appeal but preserves the Latin American path.
• The exchange ratio is fixed at 6.688 new Saipem shares per Subsea7 share, with Subsea7 shareholders also entitled to a €450 million extraordinary dividend immediately prior to completion plus a €105 million dividend tied to a permitted business divestment.
• Saipem shares were trading in the €3.90 to €4.10 range on Borsa Italiana around Jul 28 to Jul 31, closing at €3.977 on Jul 28 after a Q2 print that saw the stock fall about 8.74 percent on a cut to full-year adjusted EBITDA guidance of €1.75 billion, against a 52-week range of €2.166 to €4.846.
• Subsea7 reported Q2 2026 revenue of $1.9 billion, adjusted EBITDA of $471 million, an adjusted EBITDA margin of 24.4 percent and backlog of $13.6 billion, and raised its full-year adjusted EBITDA margin guidance to approximately 24 percent, entering the merger with visibly stronger operating momentum than Saipem stand-alone.
• Stuart Fitzgerald succeeded John Evans as chief executive of Subsea7 on Jul 1 2026 and is proposed as chief executive of the Subsea7 operating business inside Saipem7, giving Fitzgerald a full quarter of CEO tenure before the merger closes and reducing one strand of day-one integration risk.
• Saipem7 pro-forma economics remain €21 billion of revenue, more than €2 billion of adjusted EBITDA, more than €800 million of free cash flow, €43 billion of backlog with no country above 15 percent, and €300 million of annual run-rate synergies with Milan and Oslo dual listing.
• The next measurable proof points are the European Commission Phase II timetable and any signal on remedies, the Australian regulator’s decision, resolution of any Brazilian appeals against the CADE clearance, and Saipem H2 execution against the reduced €1.75 billion adjusted EBITDA guide.
