Creating a global leader in energy services

Milan, Luxembourg, 24 July 2025 - Saipem and Subsea7 announce that they have entered into a binding merger agreement, on terms and conditions in line with what previously communicated at the time of the signing of the Memorandum of Understanding on 23 February 2025. The merger of Saipem and Subsea7 will create a global leader in energy services.

Highlights

• The company resulting from the merger¹ between Saipem and Subsea7 (the "Proposed Combination") will be renamed Saipem7 ("Saipem7"), will have revenue of approx. €21 billion², EBITDA in excess of €2 billion³, will generate more than €800 million of Free Cash Flow⁴ and will have a combined backlog of €43 billion⁵
• The highly complementary geographical footprints, competencies and capabilities, vessel fleets and technologies will benefit Saipem7's global portfolio of clients
• The diversification of the geographical footprint of Saipem and Subsea7 is reflected in the combined backlog, with no single country contributing more than 15% of total⁶
• On completion, Saipem and Subsea7 shareholders will own 50% each of the share capital of Saipem7
• Subsea7 shareholders participating to the Proposed Combination will receive 6.688 new Saipem shares for each Subsea7 share held
• Subsea7 will distribute an extraordinary dividend to its shareholders for an amount equal to €450 million immediately prior to completion of the Proposed Combination
• Annual synergies expected to be approximately €300 million on a run-rate basis, which will lead to material value creation for the shareholders of Saipem7
• Saipem7 will remain incorporated in Italy and headquartered in Milan, and will have its shares listed on both the Milan and Oslo stock exchanges
• Siem Industries, reference shareholder of Subsea7, and Eni and CDP Equity, reference shareholders of Saipem, have committed to vote in favour of the Proposed Combination
• Completion of the Proposed Combination anticipated to occur in the second half of 2026

The management of both Saipem and Subsea7 confirm the compelling strategic rationale in creating a global leader in energy services, particularly considering the growing size of clients' projects. The parties believe the Proposed Combination will enhance value for all shareholders and stakeholders, both in the current market and in the long term.

Eni, CDP Equity and Siem Industries fully support the Proposed Combination and have signed a Shareholders' Agreement confirming the undertaking to vote in favour of the Proposed Combination. As part of this, to ensure a balanced leadership and governance structure, Saipem7's CEO will be designated by Eni and CDP Equity and Saipem7's Chairman of the Board of Directors will be designated by Siem Industries.

It is currently envisaged that, upon completion of the Proposed Combination, Mr Kristian Siem will be appointed as Chairman of the Board of Directors of Saipem7⁷ and Mr Alessandro Puliti will be appointed as CEO of Saipem7⁸. In addition, Mr Alessandro Puliti and Mr John Evans will be appointed respectively as the Chairman and CEO of the company that will manage the Offshore Engineering & Construction business of Saipem7. Such company will be named Subsea7, branded as "Subsea7, a Saipem7 Company", and will comprise all of Subsea7's businesses and Saipem's Asset Based Services business (including Offshore Wind).

The by-laws of Saipem7 are expected to provide for loyalty shares (double votes), which will be available, upon request, to all shareholders of Saipem7.

Strategic rationale of the Proposed Combination

The Proposed Combination will be beneficial to the clients of both Saipem and Subsea7, bringing together the respective strengths of both companies:

• Global reach and comprehensive solutions for clients: global operations and projects in more than 60 countries and a highly complementary footprint between the two companies. A full spectrum of offshore and onshore services, from drilling, engineering and construction to life-of-field services and decommissioning, with an increased ability to optimise project scheduling for clients in oil, gas, carbon capture and renewable energy
• Diversified and complementary fleet: an expanded and diversified fleet of more than 60 construction vessels enhancing Saipem7's ability to undertake a wide range of projects, from shallow water to ultra-deepwater operations, utilising a full portfolio of heavy lift, high-end J-lay, S-lay and reel-lay rigid pipeline solutions, flexible pipe and umbilical lay services, as well as market-leading wind turbine, foundations and cable lay installation capabilities
• World-class expertise and experience: a specialised, global workforce of approximately 44,000 people, including more than 9,000 engineers and project managers contributing to delivering solutions that unlock value for clients
• Innovation and technology: the combined expertise to foster innovation in offshore technologies, ensuring cutting-edge solutions for complex projects

The transaction is expected to create significant shareholder value through:

• Synergies: annual cost and capital expenditure synergies expected to be approximately €300 million from the third year after completion of the Proposed Combination, driven by fleet optimisation (utilisation and geographical positioning of vessels and equipment), procurement (longer charter periods for leased vessels and improved terms with suppliers), sales and marketing (tendering rationalisation), and process efficiencies
• More efficient capital expenditure programme: optimised allocation of capital across a broader, complementary vessel fleet
• Attractive shareholder remuneration policy: Saipem7 is expected to distribute annually to its shareholders at least 40% of its Free Cash Flow after repayment of lease liabilities
• Enhanced capital structure: a solid balance sheet expected to support an investment grade credit rating
• Greater scale in both equity and debt capital markets: access to a wider investor base and to more diversified sources of capital

Transaction structure, ownership and terms

• Saipem7 will be created through an EU cross-border statutory merger, carried out by way of absorption of Subsea7 into Saipem, with the latter to be renamed Saipem7
• Saipem7 will remain incorporated in Italy and headquartered in Milan, and will have its shares listed on both the Milan and Oslo stock exchanges
• Siem Industries (currently the largest shareholder of Subsea7) will own approximately 11.8% of Saipem7's share capital, while Eni and CDP Equity (currently the largest shareholders of Saipem) will respectively own approximately 10.6% and 6.4% of Saipem7's share capital
• Subsea7 shareholders participating to the Proposed Combination will receive 6.688 new Saipem shares for each Subsea7 share held
• Assuming all Subsea7 shareholders participate in the merger, the share capital of Saipem7 will be held 50-50% by the current shareholders of Saipem and Subsea7 on completion
• Immediately prior to completion of the Proposed Combination, Subsea7 shareholders will receive an extraordinary cash dividend of €450 million⁹
• Shareholders of Subsea7 who vote against the approval of the Proposed Combination at the Subsea7 Extraordinary General Meeting will have the right to dispose of their shares in Subsea7 for an adequate cash compensation under the conditions set out under Luxembourg company law.¹⁰ The formula that will be used to determine the cash compensation will be made available on Subsea7's website and the amount of the cash compensation determined on the basis of such formula will be announced in advance of Subsea7's Extraordinary General Meeting

The company will represent approximately 84% of the combined group's EBITDA for the last 12 months as of 31 December 2024
• Subsea7 shall be incorporated in the UK and headquartered in London.
