HIGHLIGHTS FOR THE THIRD QUARTER
  • Appointment of Mr. Otto Moltke-Hansen and Mr. Rune Magnus Lundetræ as new Directors of the Company, replacing resigned Directors.

  • An Extraordinary General Meeting of Sea1 Offshore Inc. was held on 26 September 2025 approving an application for the delisting of the company's shares from Euronext Oslo Børs. The application is on condition that the company's application for a transfer to Euronext Growth Oslo is approved.

    SUBSEQUENT EVENTS
  • Awarded a new contract for the Platform Supply Vessel Sea1 Atlas in Brazil with a duration of 3 years plus a 6-month option at market terms. Commencement will be in Q1 2026.

MARKET AND OUTLOOK

For the Construction Support Vessel market, long-term demand fundamentals remain strong; subsea backlogs from conventional EPCs are at record levels and continued to grow through the quarter. In the short term, however, we observe decreased activity in several key areas. The oil price's downward trajectory over the quarter is expected to continue into early 2026 and may contribute to the deferral of investments and spending. The subsea vessel market shows some availability after a long period of nearly or completely sold-out market.

For the rig market, one of the leading indicators for the offshore support vessel markets, global utilization increased marginally during the quarter. In the core regions (North Sea, South America, APAC) the utilization trend was opposite with a decrease of 1,3%. Rig backlog declined each month of Q3 due to limited fixing volumes. Semi-sub rig utilization bottomed out at the end of Q3 and is projected to increase over the coming 18 months.

The North Sea AHTS market was weak through most of the third quarter as some planned projects were delayed and some semi-sub rigs on the UK side came off contracts earlier than expected. Monthly average rates were significantly lower than the previous two years for both July and August. In September the market gained momentum, mainly due to vessels leaving the region and thus improving the market balance by reduced supply side. Low activity, especially on the UK sector, remains a concern for the coming months, before an expected increase in active rigs from early next year.

The semi-sub rig activity in Australia decreased as expected which will continue through next quarter. In the short term, we expect more available vessels in the region, putting pressure on rates and utilization, and potentially migration of vessels to other regions. Rig activity in the region is expected to grow again during 2nd half of next year. For the Company, the outlook is good in this region due to solid contract coverage through next year on a majority of the vessels currently operating in the region.

For South-America, market outlook is also softening in the short term on the basis of lower oil price. Petrobras, directly or indirectly contributing around 40% of global offshore services demand, has communicated intentions to reduce costs and revising their business plan. Some delays in spending and contract renegotiations are expected. The Company's outlook and contract coverage in the region is good.

RESULTS AND FINANCE Income Statements (3Q 2025 over 3Q 2024)

Operating revenues were USD 63.4 million (2024: USD 81.6 million). EBITDA was USD 34.2 million (2024: USD 45.1 million). The decrease in revenues from 3Q 2024 of USD 18.2 million is mainly explained by revenue in 3Q 2024 related to sold vessels or vessels in lay-up in 3Q 2025 (USD 17.8 million). The AHTS-fleet generated lower revenues based on a weaker spot market, this is offset by higher revenue for the Subsea and PSV vessels. The operating expenses decreased from 3Q 2024 by USD 8.0 million mainly explained by operating expenses in 3Q 2024 related to sold vessels or vessels in lay-up in 3Q 2025 (USD 4.8 million). Administrative expenses were USD

6.4 million (2024: USD 5.7 million).

Results for the Third Quarter 2025 Subsea Vessels

The Company had 1 Offshore Subsea Construction Vessel (OSCV), 2 Well-Intervention Vessels (WIVs) operating in Brazil and 1 Scientific Core-drilling vessel (SCDV)at the end of the quarter (2024: 2 OSCVs, 2 WIVs and 1 SCDV). The Subsea vessels earned operating revenues of USD 27.7 million and had 100% utilization excluding vessel in lay-up (2024: USD 37.8 million and 100%). The operating margin before administrative expenses was USD

20.2 million (2024: USD 26.1 million). The revenues and margin decreased from 2024 due to no revenues in 3Q 2025 from the sold vessel Sea1 Spearfish and due to the SCDV being in lay-up the current year.

Our new-building program of 4 new vessels continues according to plan. In September CEO Bernt Omdal attended the steel cutting ceremony for the first newbuild at the shipyard, which was an important milestone for the Company and the yard. The names of the four new buildings are Sea1 Diamond, Sea1 Citrine, Sea1 Peridot and Sea1 Coral, inspired by gemstones. As per 30 September 2025, yard instalments amounting to USD 37.9 million has been paid, USD 9.5 million has been paid in October 2025. USD 85.3 million is expected to be paid in 2026.

Anchor-Handling Tug Supply (AHTS) Vessels

The Company had 5 large AHTS vessels operating in the Asia Pacific and the North Sea and 1 medium-sized AHTS vessel at the end of the quarter (2024: 5 + 1 medium-sized AHTS). The AHTS fleet earned operating revenues of USD 22.7 million and had 88% utilization (2024: USD 28.3 million and 86%). The operating margin before administrative expenses was USD 10.9 million (2024: USD 18.1 million). The revenues and operating margin decreased from 2024 mainly due to a weaker spot market.

Platform Supply Vessels (PSVs)

The Company had 2 PSVs operating in Brazil in the fleet at the end of the quarter (2024: 2). The PSVs recorded operating revenues of USD 7.2 million and had 100% utilization (2024: USD 5.6 million and 97% utilization). The operating margin before administrative expenses for the PSVs was USD 6.0 million (2024: USD 3.1 million). The revenues and operating margin increased from 2024 mainly due to increased charter rates and increased utilization.

Other Vessels

The Company had a fleet of 4 smaller Fast Crew & Oil Spill Recovery Vessels operating in Brazil at the end of the quarter (2024: 4). Two vessels are on bareboat contracts to clients. The fleet earned operating revenues of USD 3.4 million and had 91% utilization (2024: USD 2.1 million and 83%). The operating margin before administrative expenses for the fleet was USD 2.0 million (2024: USD -0.3 million).

Note 1 - Basis of Preparation

The financial statements have been prepared under the assumption that the Company and the Parent are going concerns. The assumption is based on the terms of the financing facilities, contract backlog, Company's strong equity position, cash position and forecasted cash flows.

The consolidated financial information for the period 1 January to 30 September 2025 has been prepared in accordance with IAS 34, 'Interim financial reporting'. The consolidated interim financial information should be read in conjunction with the audited annual financial statements for the year ended 31 December 2024, which have been prepared in accordance with IFRS standards.

Note 2 - Accounting Policies

The accounting policies applied are consistent with those of the audited annual financial statements for the year ended 31 December 2024 and with new standards, amendments to standards and interpretations that have become effective in 2025.

Note 3 -Key Risks

The Company is exposed to financial, commercial and operational risks that affect the financial position, earnings and cash flow of the Company.

  1. Interest Risk

    The Company is exposed to changes in interest rates as approximately 71% of the long-term interest-bearing debt was subject to floating interest rates at the end of September 2025. The remaining portion of the debt is subject to fixed interest rates.

  2. Currency Risk

    The Company is exposed to currency risk as revenues and costs are denominated in various currencies. The Company is also exposed to currency risk on long-term debt and cash position held in non-USD currencies. See Note 6 for details.

  3. Inflation Risk

    The Company is exposed to inflation risk. The revenues may not be inflated at levels that could compensate for inflated operating cost. In addition to general inflation rates, the operating expenses related to spare parts, service-personnel and logistics within the shipping industry are further exposed to inflation.

  4. Liquidity Risk

    In January 2025 the Company refinanced debt related to its two well intervention vessels. New credit facilities from commercial banks in a total amount of USD 250 million were entered into, divided between a USD 150 million term loan and a USD 100 million revolving credit facility. Existing debt in a total amount of USD 102 million was repaid. On 30 September 2025 USD 62 million of the interest-bearing debt was classified as current debt.

  5. Commercial and operational risk

The Company is exposed to commercial risk as it operates in the cyclical oil and gas service markets and in the offshore renewables market with significant volatility in charter rates. Operational risk is related to the availability of experienced crew and technical incidents with vessels and equipment. The Company is exposed to credit risk related to counter parties' ability to meet their financial obligations.

Note that the operating revenue and operating cost for the nine vessels sold in 2024 is presented under the "Other"

segment.

1) As of the second quarter of 2025, Sea1 Offshore Inc has entered into a revenue-sharing agreement with Viking Supply Ships covering all of the large AHTS vessels owned by the parties. The vessels will be included in the revenue-sharing agreement as their pre-existing charter contracts expire.

The revenue sharing is calculated by aggregating the vessels' revenues and operating costs, which are then allocated to the vessel owners based on the number of available days for each participating vessel. This ensures that the effects from cost-efficient fleet distribution on margin allocation are balanced out.

Note 8 - Leases

The Company has entered into various operating leases for office premises, office machines and communication satellite equipment for the vessels. The lease period for the lease agreements varies and most of the leases contain an option for extension.

ALTERNATIVE PERFORMANCE MEASUREMENT (APM)

The Company has identified several APMs that are consistently applied for the reporting periods. The APMs are supplementary to the Financial Statements that are disclosed in compliance with IFRS. The APMs are disclosed to give a broader understanding of the operations, financial position, and associated risk of the Company.

EBITDA - EBITDA (Earnings before interest, taxes, depreciation and amortization, previously referred to as operating margin) is the net of operating revenue and operating and administrative expenses. For 2024 operating revenues USD 340.8 million less operating and administrative expenses at totally USD 175.1 million equals EBITDA at USD 165.7 million. The Company considers the EBITDA to be a key number when analyzing the fleets operating performance and the margin that can be applied to the finance of capital expenditures, debt service and other cash disbursements. EBITDA percentage - EBITDA, % is the nominal EBITDA calculated as a percentage of operating revenue. For 2024 the EBITDA at USD 165.7 million equals 49% of the operating revenue at USD 340.8 million. The EBITDA percentage is used to compare, period by period, the development in relative EBITDA from operations. The EBITDA-% is also used for comparing segments' relative performance. Operating Margin - Operating margin is the EBITDA before administrative expenses. For 2024 EBITDA USD

165.7 million adjusted for General administration expenses at USD 24.3 million equals operating margin at USD

190.0 million. The Company considers the Operating margin to be a key number when analyzing the fleets operating performance and the margin that can be applied to the finance of capital expenditures, debt service and other cash disbursements.

Equity Ratio - Total Equity (including Non-controlling interest) relative to Total Equity and Liabilities. OTHER DEFINITIONS Contract backlog - Firm backlog is the total, nominal value of future revenues from firm contracts, excluding optional periods. The contract backlog is categorized per year, and reflects the coming years' operating revenues that are considered firm following contracts agreed with clients. Optional backlog is the total, nominal value of future revenues from optional contract periods. Utilization - vessels' effective time on hire relative to total time available in the reporting period, excluding vessels in lay-up. The relative utilization is reflecting the time that a vessel or the fleet has been on hire with clients. Zero utilization is reported when a vessel is off-hire caused by technical issues or when idle, awaiting employment. Capital expenditure - gross capital expenditure related to tangible assets at acquisitions, upgrades, class renewals (Dry-docking) and major periodic maintenance. Earnings per share - Earnings attributable to the shareholders in the parent divided by weighted average outstanding number of shares. Comprehensive income per share - Comprehensive income for the period for the Group divided by weighted average outstanding number of shares at the end of the reporting period. Interest-bearing debt - Current and long-term debt to commercial banks and credit institutions. Net interest-bearing debt - Interest-bearing debt less cash and cash equivalents. Vessel availability - Available days are defined as the percentage of days not included in a firm contract period or option period.
