John Evans, Chief Executive Officer, said: In my final quarterly report as CEO, I am pleased to share another strong financial and operational performance that serves as a solid foundation for growth in the year ahead. Adjusted EBITDA in the first quarter of 2026 was $385 million, up more than 60% year-on-year and equating to a margin of 21%, from 15% in the prior year period. Both our Subsea and Conventional and Renewables business units delivered robust results. The Group remained focused on optimising cash generation, resulting in an increase in net cash to $198 million, including lease liabilities of $337 million.

During my six-year tenure, the Group has executed a differentiated strategy across the energy landscape - one that has driven our backlog to all?time highs, strengthened returns and enabled significant capital distributions to shareholders. Despite the geopolitical and macroeconomic uncertainty facing the world today, the outlook for Subsea7 - and, in future, Saipem7 - remains positive, supported by the attractive attributes of offshore energy. As I transition from my role as CEO and join the Board of Directors of Subsea 7 S.A., I do so with great confidence in the leadership team and in the Group's ability to seize the opportunities that lie ahead.

First quarter 2026 operational review In the first quarter, our fleet achieved 78% utilisation of Subsea and Conventional vessels and 81% utilisation of vessels within Renewables. Seven Vega and Seven Seas were active in Türkiye installing pipelines and umbilicals at the Sakarya Phase 2 project, while Seven Oceans worked in Brazil at Mero 4 and Búzios 8. Seven Arctic, Seven Atlantic and Seven Falcon were active on the Yggdrasil project in Norway, while Seven Navica prepared for pipelay at Bestla. Seven Borealis and Seven Pegasus completed the Vito waterflood project. In Renewables, Seaway Ventus installed foundations at East Anglia THREE, while Seaway Aimery and Seaway Moxie continued cable pull-in work. Seaway Strashnov, Seaway Phoenix and Seaway Alfa Lift underwent planned maintenance. Elsewhere, at Búzios 9 in Brazil, progress was made in the fabrication of rigid pipelines, while procurement continued for Búzios 11. In Türkiye, work started on engineering and procurement for the Goktepe extension to Sakarya Phase 3.

First quarter 2026 financial review Revenue was $1.8 billion, up 17% when compared with the prior year period. Adjusted EBITDA of $385 million equated to a margin of 21%, up from 15% in Q1 2025. After depreciation and amortisation of $174 million, net operating income was $210 million, equating to 12% of revenue, up from 5% in the prior year period. After net foreign exchange losses of $67 million, net finance costs of $7 million and an effective tax rate of 28%, net income was $97 million.

Net cash generated from operating activities was $256 million, including an expected $54 million unfavourable movement in net working capital. Net cash used in investing activities was $31 million and mainly related to purchases of property, plant and equipment, while net cash used in financing activities was $128 million including lease payments of $64 million. Cash and cash equivalents increased by $104 million to $1,074 million and, at 31 March 2026, net cash was $198 million, including lease liabilities of $337 million.

First quarter order intake was $1.4 billion comprising new awards of $0.9 billion (including Aseng) and escalations of $0.5 billion (including Goktepe) resulting in a book-to-bill ratio of 0.8 times. Backlog at the end of March was $13.5 billion, of which $5.5 billion is expected to be executed in the remainder of 2026, $5.0 billion in 2027 and $3.0 billion in 2028 and beyond.

Annual General Meeting As previously announced, at the Annual General Meeting on 12 May 2026, the Board of Directors will propose a dividend of NOK 13.00 per share, equating to approximately $400 million, payable on 28 May 2026.

Full year 2026 guidance With a backlog of $5.5 billion for execution in 2026, we have high visibility on anticipated revenue this year which is expected to be between $7.4 and 7.8 billion (previously between $7.0 and $7.4 billion).   We anticipate an Adjusted EBITDA margin of approximately 23% (previously approximately 22%). Although we continue to expect a modest working capital outflow in the year, plans for capital expenditure remain unchanged at $350 to 380 million, supporting an outlook for strong cash generation.

While world economies are adjusting to the uncertain implications of the current geopolitical volatility, the conflict has refocused attention on the need for energy security. This, combined with our focus on the most economically advantaged sectors of the energy industry, support a positive long term dynamic within our markets. In the near term, our exposure to regional disruption is low, accounting for less than 10% of backlog in the Middle East with associated current activities focused on the engineering and procurement phases.

At a Group level, the outlook for Subsea7 remains robust supported by a high backlog and active tendering. Overall, we are confident that the fundamentals of the energy market, combined with our differentiated offering and our strong track record of delivery, continue to position Subsea7 for success.
