Signed an agreement to sell the 2014-built OSCV Sea1 Spearfish to an independent third party. The sale will result in a gain of approximately USD 40 million. Existing debt of USD 39 million will be repaid following the transaction. The transaction is subject to customary closing conditions and closing is expected to take place in May 2025.
Forecasts for the global economy and oil demand are positive for 2025 and 2026, however the recent and rapid shifts in trade-related policies between key economies have introduced further uncertainty. For the rig market, one of the leading indicators for the offshore support vessel markets, the global utilization and total backlog have been on a slightly decreasing trend in the last months. This has put pressure on dayrates for the near term. The expected uptick in rig contracting activity and utilization may be postponed due to the ongoing mixed economic signals and trade tensions.
Recently for the Construction Support Vessel market, a handful of long-term tenders and requirements have been launched by the engineering, procurement and construction (EPC) companies for commencement in 2026 and 2027. The market is still very tight with only 2-3 larger vessels having availability during 2025. Following an expectation for a long-term demand for CSV vessels, additional newbuilding contracts for delivery in 2027 have been placed by market participants.
The North Sea AHTS market was slow at the start of the quarter as the winter season normally has low activity and also an influx of vessels returning from other regions and projects. Monthly average rates were on par with last year for January, lower in February and higher in March. At the end of March, the AHTS market was nearly sold out and rates increased sharply. Vessels moving between regions are expected to reduce the North Sea region's supply of vessels in the coming months. On the demand side the UK sector floater rig count is a cause of concern. However the positive trend on the Norwegian side may replace the decline in UK activity. Project activity remains good for the season and the AHTS market is expected to gain momentum over the next months, however, with high volatility in the spot market.
The semi-rig activity in Australia will see a temporary decrease in 2025, which may result in more available support vessels in the region, or migration of vessels to other regions. This could, in the short term, lead to regional pressure on rates and utilization before we see new rig activity, which is expected in 2026.
The strongest drilling unit demand is anticipated in South America, Africa and Middle East. South America is likely to drive floating drilling unit demand, while the Middle East will lead the jack-up demand. FPSO installations are

also a significant demand driver for all vessel segments, where South America (Brazil) is the region with highest planned activity for the coming years.
Moderate further growth in the OSV market is expected for the rest of the year. A tight supply side in the Subsea vessel segment is expected to continue as there is a limited number of newbuilds to be delivered in the short term.
Operating revenues were USD 68.5 million (2024: USD 83.2 million). EBITDA was USD 40.3 million (2024: USD 32.9 million). The decrease in revenues from 1Q 2024 of USD 14.6 million is mainly explained by the sale of 9 vessels in July 2024 (USD 23.3 million in revenue for the sold vessels in 1Q 2024), in addition to Joides Resolution entering lay-up in October 2024 (USD 8.5 million in revenue in Q1 2024). The decrease was partly offset by uplift in charter rates, particularly in the AHTS-segment, and mobilization revenues related to the Rig Consortium Contract in Australia. The operating expenses decreased from 1Q 2024 by USD 22.2 million mainly due to the sale of 9 vessels in July 2024 (USD 15.9 million in operating cost for the sold vessels in 1Q 2024) and Joides Resolution being in lay-up (USD 3.6 million in operating cost in Q1 2024). In addition, operating expenses were reduced due to receival of final payment of USD 3.2 million from a claim related to a previous charter contract. The amount was recorded as a realized loss in 2016 and the received payment is reported as negative operating expenses. The decrease in operating expenses was partly offset by increased cost for AHTS vessels mobilizing for the Rig Consortium Contract. Administrative expenses were USD 5.8 million (2024: USD 5.6 million).
Operating profit/(loss) was USD 27.0 million (2024: USD 14.7 million) after depreciation and amortization expenses of USD 13.5 million (2024: USD 18.2 million). Reduction of depreciation and amortization is mainly explained by fewer owned vessels in the quarter, following the sale of nine vessels in July 2024. Other gain/(loss) mainly relates to a profit-sharing agreement in relation to the sale of the AHTS-vessels in July 2024.
Net financial items were USD -4.0 million (2024: USD -3.0 million) and include a net revaluation gain/(loss) of currency items of USD 4.9 million (2024: USD 3.3 million), of which USD 7.0 million was unrealized (2024: USD 4.5 million).
The net profit/(loss) attributable to shareholders was USD 22.2 million (2024: USD 11.8 million), representing USD 0.14 per share (2024: USD 0.05 per share).
Shareholders' equity was USD 332.6 million on 31 March 2025 equivalent to USD 2.17 per share. Total book equity ratio was 41.7 %.
The gross interest-bearing debt was equivalent to USD 395.9 million. In the first three months of 2025, the Company made principal repayments of USD 107.9 million. In the same period, the Company made interest payments of USD 3.4 million. The weighted average cost of debt for the Company was approximately 7.0% p.a. on 31 March 2025 (31 March 2024: 7.2%). 25% of interest-bearing debt has a fixed interest rate. On 31 March 2025 USD 65 million of the interest-bearing debt was classified as current debt.

On 31 March 2025 the share capital was USD 153.544 million, representing a total of 153,543,734 shares with a nominal value of USD 1.00 per share. Major shareholder Kistefos AS owns 79,585,160 shares, equal to 51.8%. Kistefos is represented at the Board of Directors by Chairman Christen Sveaas.
Net cash flow from operating activities for the first three months of 2025 was USD 34.3 million and the cash position on 31 March 2025 was USD 52.6 million. Cash flow from investing activities was USD -12.6 million. Cash flow from financing activities was USD -37.3 million.
On 31 March 2025, the owned fleet totaled 17 vessels plus 4 vessels under construction (2024: 26 vessels, including partly owned vessels). One vessel was in lay-up at the end of the quarter (2024: nil). In addition to the owned fleet, the Company performs ship management services for 8 vessels. The management for 2 of these vessels will be transferred to a new manager during the period from April-June 2025. 6 vessels are owned by Viking Supply Ships. The overall fleet utilization in the quarter was 88% (2024: 89% for the Sea1 fleet), excluding vessels in lay-up.
Vessel availability (excluding firm backlog and options) for the owned fleet per 31 March 2025 is as presented below. Note that the laid-up scientific core-drilling vessel "Joides Resolution" is included in the Subsea segment.
| 2025 | 2026 | 2027 | |
|---|---|---|---|
| PSV | 0% | 0% | 30% |
| Subsea | 20% | 37% | 54% |
| AHTS | 34% | 58% | 67% |
| FC&OSRV | 0% | 24% | 25% |
Note that the operating revenue and operating cost for the nine vessels sold has been moved from its original segment and is now presented under the "Other" segment also for the comparable figures for 2024.
The Company had 2 PSVs in the fleet at the end of the quarter (2024: 2, excluding the 4 PSV vessels sold to Siem). The PSVs recorded operating revenues of USD 5.8 million and had close to 100% utilization (2024: USD 3.9 million and close to 100%). The operating margin before administrative expenses for the PSVs was USD 3.6 million (2024: USD 1.3 million).
The Company had 2 Offshore Subsea Construction Vessels (OSCVs), 2 Well-Intervention Vessels (WIVs) and 1 Scientific Core-drilling vessel at the end of the quarter (2024: 2 OSCVs, excluding the 2 OSCV vessels sold to Siem, 2 WIVs and 1 Scientific core-drilling vessel). The Subsea vessels earned operating revenues of USD 33.1 million and had 100% utilization excluding vessel in lay-up (2024: USD 33.7 million and 87%). The operating margin before administrative expenses was USD 28.5 million (2024: USD 21.6 million). The revenues decreased from 2024 despite higher rates for the OSCV's, as the Scientific Core-drilling vessel did not generate revenues in 1Q 2025. The operating margins increased from 2024, mainly due to higher rates and a one-off payment of USD 3.2 million as

the final settlement from a claim related to a previous charter contract. This was partly offset by the Scientific coredrilling vessel that was in lay-up in 1Q 2025.
The Company had 5 large AHTS vessels and 1 medium-sized AHTS vessel at the end of the quarter (2024: 5, excluding the 3 AHTS vessels sold to Siem + 1 medium-sized AHTS). The AHTS fleet earned operating revenues of USD 24.1 million and had 69% utilization (2024: USD 18.1 million and 80%). The operating margin before administrative expenses was USD 10.5 million (2024: USD 6.7 million). The revenues and operating margin increased from 2024 mainly due to increased charter rates and invoice of mobilization- and demobilization fees.
The Company had a fleet of 4 smaller Fast Crew & Oil Spill Recovery Vessels at the end of the quarter (2024: 4). No vessels were in lay-up at the end of the quarter (2024: nil). Two vessels are on bareboat contracts to clients. The fleet earned operating revenues of USD 3.6 million and had 100% utilization (2024: USD 3.8 million and 99%). The operating margin before administrative expenses for the fleet was USD 1.6 million (2024: USD 1.1 million).
The Company has a continuous focus on safe and sustainable operations.
During 1Q 2025, Sea1 Offshore have operated diligently towards ESG goals, KPI's and strategy by means of several points of impact, such as:

For fleet emissions, the Company reports on the Carbon Intensity Indicator (CII), a proxy that measures grams CO2 total tailpipe emission per hour in operation. The CII was at the end of 4Q 2024 at 148.7g/kWh, and as per 31 March 2025 at 162g/kWh. The increase is mainly due to change in fleet mix. The Company proceeds with strenuous efforts to reduce emissions. The Company's goal of 50% reduction in 2030 compared to 2008 levels is in line with recommendations given by the Norwegian Shipowners Association.
In 1Q 2025, there was one minor oil spill to sea, no other environmental incidents.
The Company's main KPI on safety, Total Recordable Injury Frequency (TRIF), was 1.03 for the quarter (excl four vessels in Brazil), positively below our target of 1.95.
In the quarter there was zero Lost Time Incidents (LTI), giving a rolling 12month average of 0.66.
At end of the quarter, the relative share of female staff was 40% onshore and 7% offshore.
As per our Human Rights policy, Sea1 Offshore is committed to the principles of non-discrimination and equal opportunity, regardless of gender, nationality, beliefs, or other factors.
Business Compliance, Anti-Corruption, sanctions, and Due Diligence of partners has high focus.

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 31 March 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.
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.
The Company is exposed to financial, commercial and operational risks that affect the financial position, earnings and cash flow of the Company.
The Company is exposed to changes in interest rates as approximately 75% of the long-term interest-bearing debt was subject to floating interest rates at the end of March 2025. The remaining portion of the debt is subject to fixed interest rates.
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.
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, servicepersonnel and logistics within the shipping industry are further exposed to inflation.

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 31 March 2025 USD 65 million of the interest-bearing debt was classified as current debt.
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 has been moved from its original segment and is now presented under the "Other" segment.

The Company is subject to taxes in several jurisdictions where significant judgement is required in calculating the tax provision for the Company. There are several transactions for which the ultimate tax cost is uncertain and for which the Company makes provisions based on internal estimates, tax treaties and tax regulations in countries of operation and appropriate external advice. Where the final tax outcome of these matters is different from the amounts that were initially recorded, such difference will impact the tax charge in the period in which the outcome is determined. The Company holds a significant balance of losses carried forward and other tax positions that may be offset against future tax positions, provided that the Company earns taxable profits and that current tax regulations are maintained. As the timing and valuation of the tax positions are uncertain, the Company has included only a minor share of its potential deferred tax asset in the Balance sheet.

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. The interest rates in the calculation of net present values are in the range of 9%-13% depending on the base currency, the nature of the lease and the length of the leasing agreement.

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.

Equity Ratio – Total Equity (including Non-controlling interest) relative to Total Equity and Liabilities.
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.
