RNS Number : 5625TGulf Marine Services PLC07 September 2026 Gulf Marine Services PLC ('Gulf Marine Services', 'GMS', 'the Company' or 'the Group') Interim results for the six-month period ended 30 June 2026 GMS, a leading provider of self-propelled, self-elevating support vessels to the offshore industry, is pleased to announce its interim results for the six-month period ended 30 June 2026 (H1 2026). Overview H1 2024 H1 2025 H1 2026 H1 2026 versus US$ m US$ m US$ m H1 2025 change Adjusted revenue1 80.7 87.1 84.1 -3% Adjusted EBITDA1 47.7 50.8 43.8 -14% Gross profit 38.8 35.9 2.0 -94% Net profit/(loss) 7.4 3.9 (14.8) -479% Adjusted net profit1 7.4 14.1 6.9 -51% Net leverage ratio 2.62:1 1.73:1 1.75:1 +1% Net bank debt 238.5 179.4 185.4 +3% 1 This represents an Alternative Performance Measure (APM) as defined in the Glossary which is included in Note 5 to the interim consolidated Financial Statements. H1 Financial and Operational Highlights: · Adjusted revenue decreased by 3% to US$ 84.1 million (H1 2025: US$ 87.1 million), mainly due to the impact of the conflict in the Gulf. As announced in early March 2026, four vessels were temporarily evacuated in a Gulf country as a precautionary measure. All these vessels were back to hire on the same contracts by middle of June 2026. The estimated loss of revenue due to war was US$ 11.6 million while the impact on adjusted EBITDA and net profit amounted to US$ 12.8 million. Management is engaged in active discussions with clients to recover the revenue loss. · Gross profit decreased to US$ 2.0 million (H1 2025: US$ 35.9 million), mainly resulted from the recognition of impairment loss on property and equipment and impact of regional conflict. · Average fleet utilisation declined to 75% (H1 2025: 87%). Apart from the impact of the conflict in the Gulf, utilisation was also affected by the planned preparation of a large vessel in Europe during the first quarter of 2026, ahead of its new contract. · Average day rates improved by 7% to US$ 37.4k (H1 2025: US$ 35.1k), due to new contracts at better rates. · Adjusted EBITDA declined by 14% to US$ 43.8 million (H1 2025: US$ 50.8 million) driven mainly by the impact of the conflict in the Gulf. · GMS acquired a brand-new mid-class vessel in January 2026, bringing the total fleet being operated by GMS to 15 vessels. This acquisition has been partially financed through a US$ 37.4 million bridge loan, which was merged into the existing bank facilities subsequent to the reporting period. As a result, net leverage ratio at 30 June 2026 increased to 1.75x (31 December 2025: 1.39x). This ratio is still below the Group's 2.0x target. · In early May 2026, GMS announced its entry into new markets, namely Latin America and Africa. GMS was able to secure contracts for the new mid-class vessel in Latin America. The entry into Africa represents a new revenue
Page 2
stream, a third-party vessel management service. The financial impact of these new contracts will be visible in H2 2026. · Impairment loss recognised on property and equipment during the period was US$ 22.7 million (H1 2025: nil), primarily due to the ongoing geopolitical situation in the Gulf region. · Group incurred a net loss of US$ 14.8 million (H1 2025: net profit of US$ 3.9 million) primarily due to the recognition of an impairment loss and lower EBITDA, partially offset by a lower tax expense and the impact of change in the fair value of derivatives. On an adjusted basis (after excluding the impact of impairment and other adjusting items), adjusted net profit decreased to US$ 6.9 million (H1 2025: US$ 14.1 million) predominantly due to reduced adjusted EBITDA. · Adjusted basic earnings per share for the period were US$ 0.60 (H1 2025: US$ 1.26), while the diluted earnings per share declined to US$ 0.59 (H1 2025: US$ 1.23), due to lower adjusted net profit. · Until there is greater clarity on the geopolitical risks impacting the Gulf, the implementation of the GMS shareholder distribution policy continues to be deferred. Outlook: · Despite the impact of the conflict in the Gulf during H1 2026, adjusted EBITDA in the range of US$ 105-115 million continues to be targeted for 2026. This target assumes the situation will not return to active military actions. · Expected earnings recovery in H2 2026 will be driven by the expansion into Latin America as well as the full operational impact of redeployment of an E-class vessel in Europe which started in April 2026. · Secured backlog was US$ 659 million on 17 August 2026 (31 December 2025: US$ 606 million), which reflects the additional contract awards and extensions announced over the last 6 months, offset by the revenue recognised. This underscores the ongoing strength in demand for our vessels across the various markets in which we operate. Mansour Al Alami, Executive Chairman, GMS said: "The first half of the year was significantly impacted by disruptions resulting from the war in the Gulf, but our core businessremains strong with improved average day rates and higher backlogs. Supported by expansion in Latin America alongsidefully operational assets deployed in Europe, performance is expected to rebound in the second half of 2026. This expectationassumes that the Gulf region will not return to active military actions." Enquiries: Gulf Marine Services PLC Mansour Al Alami Executive Chairman Alex Aclimandos Chief Financial Officer Tel: +44 (0)20 7603 1515 Celicourt Communications Philip Dennis Mark Antelme Kristine Qevani Tel: +44 (0) 20 7770 6424 Chairman's Review Group performance In the first half of 2026, the Group's adjusted revenue decreased by 3% to US$ 84.1 million (H1 2025: US$ 87.1 million), mainly due to the impact of the war in the Gulf (see below) which resulted in an estimated loss of revenue amounting to US$ 11.6 million. Further, a large vessel was under preparation for its contract in Europe during the first three months of the year and only commenced its charter operations on 1 April 2026. The same vessel was fully operational on the same period last year. As a result of these events, the average fleet utilisation declined to 75% (H1 2025: 87%). The loss of revenue, together with the incremental operational costs of US$ 1.2 million, due to the war in the Gulf, resulted in a decrease in adjusted EBITDA of US$ 43.8 million, compared to US$ 50.8 million reported in H1 2025. Management is engaged in active discussions with clients to recover the revenue loss. Conflict in the Gulf During early March, we were instructed to evacuate the Group's four vessels in one of the countries affected by the conflict, as a precautionary measure. All these vessels gradually returned to work on the same contracts by the middle of June 2026. As the geopolitical risks are still high, Management continues to monitor the situation closely. Growth and Business Development

GMS invested and acquired a brand-new mid-class vessel to support the Group's growth ambitions. This was partially financed through a US$ 37.4 million bridge loan, which was merged into the existing bank facilities subsequent to the reporting period. As a result, the net leverage ratio at 30 June 2026 increased to 1.75x (31 December 2025: 1.39x). This ratio remains below the Group's 2.0x target. In early May 2026, GMS announced its entry into two new markets: Latin America, via a contract for the brand-new mid-class vessel, and Africa, through a third-party vessel management agreement, which represents a new revenue stream. The financial impact of these expansions will be visible in H2 2026. The contract awards and extensions across the Group during the period have a combined total charter period of 12.3 years (H1 2025: 8.1 years), resulting in an increased backlog of US$ 628 million as at 30 June 2026 (31 December 2025: US$ 606 million). Further, average day rates improved to US$ 37.4k (H1 2025: US$ 35.1k). Governance There were no changes in the composition of the Board during the period. During the Annual General Meeting held on 18 June 2026, all the Directors received overwhelming support from the shareholders for re-appointment. Outlook GMS reaffirms its FY2026 adjusted EBITDA guidance of US$ 105-115 million. Despite H1 2026 operational disruptions, resulting from the conflict in the Gulf, performance is expected to rebound in H2 2026, assuming no return to active military actions. This recovery will be driven by earnings contributions from the Group's expansion into Latin America, and the full- year operational impact of the additional large vessel deployed in Europe from 1 April 2026. Until we have a greater clarity on the geopolitical risks, we continue to defer the implementation of our shareholder distribution policy. Mansour Al Alami Executive Chairman 04 September 2026 Notes to Editors: Gulf Marine Services PLC, a company listed on the London Stock Exchange, was founded in Abu Dhabi in 1977 and hasbecome a world-leading provider of advanced self-propelled self-elevating support vessels (SESVs). The fleet serves theoffshore energy industries from its offices in the United Arab Emirates, Saudi Arabia, Qatar and the United Kingdom. TheGroup's assets are capable of serving clients' requirements across the globe, including those in the Middle East, South EastAsia, West Africa, North and South America, the Gulf of Mexico, and Europe. The GMS fleet of 15 SESVs is amongst the youngest in the industry. The vessels support GMS's clients in a broad range ofoffshore platform refurbishment and maintenance activities, well intervention work, and offshore wind turbine maintenancework (which are opex-led activities), as well as offshore platform installation and decommissioning and offshore wind turbineinstallation (which are capex-led activities). The SESVs are categorised by size - K-Class (Small), S-Class (Mid), and E-Class (Large) - with these capable of operating in water depths of 45m to 80m depending on leg length. The vessels are four-legged and are self-propelled, which means they do not require tugs or similar support vessels for moves between locations in the field; this makes them significantly more cost-effective and time-efficient than conventional offshore support vessels without self-propulsion. They have a large deck space, crane capacity, and accommodation facilities (for up to 300 people) that can be adapted to the requirements of the Group's clients.

Net leverage ratio 2.62:1 1.73:1 1.75:1 +1% Net bank debt 238.5 179.4 185.4 +3% 1 This represents an Alternative Performance Measure (APM) as defined in the Glossary which is included in Note 5 to the interim consolidated Financial Statements. Revenue and segment information The Group reported a 3% decline in adjusted revenue to US$ 84.1 million (H1 2025: US$ 87.1 million), primarily due to impact of the conflict in the Gulf, where four of the Group's vessels were instructed to evacuate as a precautionary measure. Although all these vessels were back on hire on the same contract by the middle of June 2026, conflict in the Gulf region resulted to an estimated loss of revenue amounting to US$ 11.6 million during H1 2026. The conflict in the Gulf resulted in a decline in average fleet utilisation to 75% (H1 2025: 87%). Average fleet utilisation was also impacted by the planned mobilisation work to prepare a large vessel ahead of its charter in Europe, which started on 1 April 2026. This vessel remained off hire for the entire first quarter of 2026, compared to Q1 2025 where it was fully operational. GMS started to operate a leased large vessel in Q2 2025. This vessel was operational for five months in H1 2026 versus twomonths in the prior period, delivering an incremental adjusted revenue of US$ 4.1 million. Further, average day ratesimproved by 7% to US$ 37.4k (H1 2025: US$ 35.1k) during the period ended 30 June 2026. The table below shows the revenue contributions per geographical region: Geographical region H1 2026 H1 2025 Adjusted revenue US$ m % Adjusted revenue US$ m % Middle East 66.9 80% 77.9 89% Others 17.2 20% 9.2 11% Total 84.1 100% 87.1 100% The reduction in adjusted revenue contribution from the Middle East is mainly the result of the war in the Gulf as well as the transfer of a large vessel to Europe. The transfer of a large vessel to Europe enhances the Group's presence in the renewables sector. GMS broadened its geographical footprint in the second half of 2026 as its newly acquired mid-class vessel is on hire in LatinAmerica. The table below shows the contribution to revenue and segment gross profit made by each vessel class during the period: (US$'000) Vessel class Adjusted revenue Adjusted gross profit before depreciation, amortisation and impairment charges H1 2026 H1 2025 H1 2026 H1 2025 K-Class vessels 20,920 26,109 8,801 14,167 S-Class vessels 21,786 22,755 15,925 16,973 E-Class vessels 41,350 38,202 26,791 26,462 Total 84,056 87,066 51,517 57,602 Cost of sales and general & administrative expenses Underlying cost of sales1 (which excludes depreciation, amortisation and impairments) increased to US$ 32.5 million (H1 2025: US$ 29.5 million) mainly due to five months of operation of a leased large vessel as compared to two months in the same period last year, redeployment of a large vessel in Europe in April 2026 and the incremental operational costs due to the conflict in the Gulf. As a percentage of adjusted revenue, underlying cost of sales increased to 39% (H1 2025: 34%). Depreciation, amortisation and impairments charged to cost of sales increased to US$ 44.9 million (H1 2025: US$ 22.1 million). This was driven mainly by recognition of an impairment loss during the period amounting to US$ 22.7 million (H1 2025: nil). The impairment loss resulted primarily from the ongoing geopolitical situation in the Gulf region. Underlying general and administrative expenses1 (which excludes depreciation and amortisation) increased to 9.1% (H1 2025: 8.2%) as a percentage of adjusted revenue. 1Represents costs excluding depreciation, amortisation, impairments and other exceptional costs. A reconciliation of this measure is provided in Note 5 tothe condensed consolidated interim financial statements.

Finance expenses Finance expenses decreased by 6% to US$ 7.6 million (H1 2025: US$ 8.1 million), with GMS benefiting from an improvement of its net leverage ratio, resulting from the bank margin being reduced by 50 bps starting Q2 2025, and slightly lower market interest rates compared to the prior period. Considering the new bridge loan amounting to US$ 37.4 million, which was used to partially finance the acquisition of a brand-new mid-class vessel, gross debt increased to US$ 201.8 million (31 December 2025: US$ 184.4 million). The portion of gross debt hedged by interest rate swaps rose to US$ 82.9 million (31 December 2025: US$ 32.7 million), as a result of a new interest rate swap contract entered during the current period. Fair value of derivatives During the period, the fair value gains on derivatives was US$ 0.3 million, as compared to US$ 4.2 million fair value loss from the same period last year. In the previous period, the derivative is attributable to the warrants which were concluded on 30 June 2025. In the current period, derivatives pertain to interest rate swaps and forward foreign exchange contracts to mitigate the risks of adverse fluctuations in interest and currency exposures of the term loan. For further details, please refer to the derivative financial instruments' disclosure in Note 18 to the condensed consolidatedinterim financial statements. Tax expenses Tax expense was US$ 2.6 million (H1 2025: US$ 12.9 million). In the prior period, the Group recorded a charge related to one- time impact of a tax ruling received in certain jurisdictions as announced on 14 May 2025. Earnings The Group incurred a net loss of US$ 14.8 million (H1 2025: net profit of US$ 3.9 million), primarily due to the recognition of an impairment loss during the period ended 30 June 2026, amounting US$ 22.7 million, and lower EBITDA (as discussed above), offset by lower tax expenses and the impact of change in the fair value of derivatives. On an adjusted basis (after excluding the impact of impairment and other adjusting items), net profit was US$ 6.9 million (H1 2025: US$ 14.1 million). Cash flow and liquidity The Group generated operating cash flows of US$ 44.9 million (H1 2025: US$ 41.2 million) during the period, spent US$ 57.8 million (H1 2025: US$ 12.9 million) on its investing activities, while the net cash inflow from financing activities was US$ 1.6 million (H1 2025: net outflow of US$ 53.3 million). Capital expenditure increased to US$ 58.8 million (H1 2025: US$ 12.9 million), primarily due to the acquisition of a brand- new mid-class vessel, necessary spending for vessel improvements and upgrades, and drydocking activities. The acquisition of a new vessel was partially financed by US$ 37.4 million bridge loan, which was merged into the existing syndicated bank facilities, subsequent to the reporting period ended 30 June 2026. The Group has available working capital facility of US$ 21.8 million (31 December 2025: US$ 22.7 million). Subsequent to the period ended 30 June 2026, the total working capital facility increased by US$ 7.5 million. Balance sheet Total assets at 30 June 2026 increased to US$ 708.7 million (31 December 2025: US$ 699.9 million). Net additions to property and equipment as well as on drydocking expenditure amounted to US$ 13.8 million, after the acquisition of a brand-new mid-class vessel, depreciation and amortisation of US$ 18.0 million (H1 2025: US$ 17.3 million) and impairment charges of US$ 22.7 million (H1 2025: nil). Prepayments increased to US$ 14.4 million (31 December 2025: US$ 4.5 million) due to the mobilisation costs spending related to the new contracts, and reduction in cash and cash equivalents to US$ 16.4 million (31 December 2025: US$ 27.8 million). Total liabilities increased to US$ 300.8 million (31 December 2025: US$ 277.7 million). This was mainly due to the net increase in bank borrowings, by US$ 17.2 million, as a result of the bridge loan obtained to finance the acquisition of a brand-new mid-class vessel, an increase in trade and other payables by US$ 9.2 million for the higher contract liabilities that will be recognised as revenue in future over the term of the contract with the customers, offset by a reduction of lease liabilities by US$ 3.9 million. Total equity decreased to US$ 407.9 million (31 December 2025: US$ 422.3 million), primarily due to the net loss incurred during the period of US$ 14.8 million (H1 2025: net profit of US$ 3.9 million). Net Bank Debt and Borrowings In January 2026, GMS obtained a bridge loan amounting to US$ 37.4 million to partially finance the acquisition of a brand-new mid-class vessel. Subsequent to reporting period ended 30 June 2026, this bridge loan was merged into the existingbank facilities and will be settled in 20 quarterly instalments over five years starting September 2026. Further, the totalworking capital facility increased by US$ 7.5 million as a result of this latter transaction.
Page 6
During the period ended 30 June 2026, total repayment on bank borrowings amounted to US$ 20.0 million (H1 2025: US$ 46.8 million). Net bank debt increased to US$ 185.4 million (31 December 2025: US$ 156.6 million), while the net leverage ratio increased to 1.75x (31 December 2025: 1.39x). The net leverage ratio is still below the Group's 2.0x target. Going concern Over the years, the Group was able to reduce the net leverage ratio to 1.75x as at 30 June 2026 (from as high as 8.06x as at 31 December 2020), below the 2.0x target. This situation strengthens its agility and resilience. The Group's forecasts indicate that it will have sufficient liquidity to meet its obligations for at least the next 12 months. Accordingly, the condensed consolidated interim financial statements of the Group for the current period have been prepared on the Going Concern basis. For further details please refer the going concern disclosure in Note 2 to the condensed consolidated interim financial statements. Risks and uncertainties Several risks and uncertainties could significantly influence the Group's performance for the rest of 2026. The Directorsbelieve that the principal risks and uncertainties have remained consistent since the release of the Annual Report for theyear ended 31 December 2025. For a comprehensive analysis of these risks and the Group's mitigation strategies, pleaserefer to pages 23 to 28 of the 2025 Annual Report, available at www.gmsplc.com. · Utilisation - Utilisation levels might decline due to several factors: regional conflicts that may disrupt offshoreoperations, restrict access or cause project delays; dependence on a small number of major customers; the cyclicalnature of the industry; additional tonnage expected to enter the market during the remainder of 2026 and into2027, the risk that our K-Class vessels become less competitive against a growing number of larger new-buildvessels; and increased standard specifications required by customers, which could necessitate costly upgrades toremain compliant. · Middle East local content requirements - National Oil Companies (NOCs) in the Middle East maintain local contentrequirements in their tender processes, favouring suppliers that enhance local investment and spending. This couldlimit GMS's ability to secure new contracts or result in reduced profit margins on existing contracts, affectingoperating cash flows and net profitability. · Inability to deliver safe and reliable operations - Geopolitical events may affect vessel operations by restrictingcrew travel or access to certain regions. A serious environmental or safety incident involving our employees,visitors or contractors could harm both our commercial interests and our reputation. Inadequate preparation forcritical situations, including equipment failure, unmet client requirements or unpredictable weather, couldnegatively affect business performance, and insufficient insurance coverage may expose the Group to significantfinancial loss. · Liquidity and covenant compliance - The Group faces short-term liquidity risks arising from timing mismatchesbetween cash inflows and outflows, delayed or slow-paying clients, and unexpected expenses. Bank covenants areclosely monitored given the Group's sensitivity to factors such as vessel utilisation, operational downtime andinterest rates. Any breach of these covenants could trigger an event of default, allowing lenders to accelerate loanrepayments and potentially exercise security over the Group's assets. · People - Attracting, retaining, recruiting and developing a skilled workforce remains important. Losing skills orfailing to attract new talent has the potential to undermine performance. · Legal, economic and political conditions - Political instability in the regions in which the Group operates couldaffect its operations. In particular, the ongoing conflict and heightened geopolitical tensions in the Gulf regioncould disrupt vessel movements, restrict access to certain areas, affect crew travel and deployment, and result indelays or interruptions to customer projects and offshore operations. As many key crew members are sourced fromEastern Europe and Southeast Asia, such instability may disrupt recruitment, retention and deployment ofpersonnel. High interest rates and inflation may continue to affect the Group's liquidity and profitability. · Compliance and regulation - Non-compliance with anti-bribery, corruption, tax, financial reporting and otherregulatory requirements could harm the Group's reputation, stakeholder relationships and financial position.Operating across multiple jurisdictions exposes the Group to a complex web of international, federal and local lawsand regulations, including on health, safety and the environment, compliance with which is becoming more costlyand complex. Failure to adhere to these requirements, or to provide timely and accurate financial reporting or taxcompliance (including transfer pricing), could result in regulatory investigations or significant penalties. · Cybercrime - security and integrity - The Group's reliance on technology infrastructure and digital systems,including exposure to phishing and other cyber incidents, could result in system outages, data breaches orinappropriate transactions. This exposes GMS to the risk of financial loss, compliance challenges and reputationaldamage. · Climate change - Climate change presents both transition and physical risks to the Group. Transition risks arisefrom the global shift toward a lower-carbon economy, which may influence investor sentiment and clientpreferences. Physical risks, including rising temperatures and sea levels, may affect working hours, operatingconditions and vessel deployment. Increasing regulatory requirements could also require enhanced reporting orthe adoption of lower-emission technologies. RESPONSIBILITY STATEMENT

We confirm to the best of our knowledge: a) the condensed set of financial statements, which have been prepared in accordance with the applicable accounting standards, gives a true and fair view of the assets, liabilities, financial position and profit or loss of Gulf Marine Services plc and its undertakings, included in the consolidation as a whole as required by DTR 4.2.4R; b) the interim management report includes a fair review of the information required by DTR 4.2.7R; and c) the interim management report includes a fair review of the information required by DTR 4.2.8R. By order of the Board Mansour Al Alami Executive Chairman 04 September 2026 Alex Aclimandos Chief Financial Officer 04 September 2026 INDEPENDENT REVIEW REPORT TO GULF MARINE SERVICES PLC (THE "ENTITY") Conclusion We have been engaged by the Entity to review the Entity's condensed set of consolidated financial statements inthe half-yearly financial report for the six months ended 30 June 2026 which comprises the condensedconsolidated statement of comprehensive income, the condensed consolidated statement of financial position, thecondensed consolidated statement of changes in equity, the condensed consolidated statement of cash flows, asummary of material accounting policies and other explanatory notes. Based on our review, nothing has come to our attention that causes us to believe that the condensed set ofconsolidated financial statements in the half-yearly financial report for the six months ended 30 June 2026 is notprepared, in all material respects in accordance with International Accounting Standard 34 Interim FinancialReporting ("IAS 34") as adopted for use in the UK and the Disclosure Guidance and Transparency Rules ("theDTR") of the UK's Financial Conduct Authority ("the UK FCA"). Basis for conclusion We conducted our review in accordance with International Standard on Review Engagements (UK) 2410 Reviewof Interim Financial Information Performed by the Independent Auditor of the Entity ("ISRE (UK) 2410") issued foruse in the UK. A review of interim financial information consists of making enquiries, primarily of personsresponsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards onAuditing (UK) and consequently does not enable us to obtain assurance that we would become aware of allsignificant matters that might be identified in an audit. Accordingly, we do not express an audit opinion. Emphasis of Matter - Geopolitical developments in the Middle East and Gulf region We draw attention to Note 2 to the condensed consolidated financial statements, which sets out the Directors'evaluation of the potential impact of ongoing regional conflict developments in the Middle East on the Group'soperations and financial position. As described in that note, the geopolitical situation in the Gulf has led tooperational disruptions, including the suspension of certain vessel activities and increased uncertainty in utilisationlevels. While the situation continues to evolve and may create uncertainty in regional economic and operatingconditions, management has assessed the Group's liquidity, forecast cash flows, and the mitigating actionsavailable should conditions worsen. Based on this assessment, the Directors have concluded that no materialuncertainty exists that may cast significant doubt on the Group's ability to continue as a going concern. Ourconclusion is not modified in respect of this matter. Conclusions relating to going concern Based on our review procedures, which are less extensive than those performed in an audit as described in theBasis for conclusion section of this report, nothing has come to our attention that causes us to believe that thedirectors have inappropriately adopted the going concern basis of accounting, or that the directors have identifiedmaterial uncertainties relating to going concern that have not been appropriately disclosed.

GULF MARINE SERVICES PLC Notes to the Condensed Consolidated Interim Financial Statements for the period ended 30 June 2026 1 Corporate information Gulf Marine Services PLC ("GMS" or the "Company") is a Company which is registered and was incorporated in England and Wales on 24 January 2014. The Company is a public limited liability company with operations mainly in the Gulf Cooperation Council (GCC) and Europe. The address of the registered office of the Company is Ground Floor Heritage House 2-14 Shortlands London, W6 8DJ. The registered number of the Company is 08860816. The principal activities of GMS and its subsidiaries (together referred to as the "Group") are chartering and operating a fleet of specially designed and built vessels. All information in the notes relate to the Group, not the Company unless otherwise stated. The Group is engaged in providing self-propelled, self-elevating support vessels (SESVs) that present a stable platform for delivery of a wide range of services throughout the total lifecycle of offshore oil, gas and renewable energy activities, and which are capable of operations in the GCC and other regions. The condensed consolidated interim financial statements of the Group for the six-month period ended 30 June 2026 were authorised for issue on 04 September 2026. The condensed consolidated interim financial statements do not comprise statutory accounts within the meaning of Section 434 of the Companies Act 2006. The condensed consolidated interim financial statements have been reviewed, not audited. The Group issued statutory consolidated financial statements for the year ended 31 December 2025, which were prepared in accordance with UK-adopted International Accounting Standards in conformity with the requirements of the Companies Act 2006. Those consolidated financial statements were approved by the Board of Directors on 13 April 2026. The auditor's report on those consolidated financial statements was unqualified and included an Emphasis of Matter paragraph drawing attention to the Directors' assessment of the potential impact of ongoing regional conflict developments in the Middle East on the Group's operations, financial position and going concern assessment. The auditor's report did not contain a statement under section 498(2) or section 498(3) of the Companies Act 2006. A copy of the statutory consolidated financial statements for the year ended 31 December 2025 has been delivered to the Registrar of Companies. 2 Material accounting policies The accounting policies and methods of computation adopted in the preparation of these condensed consolidated interim financial statements are consistent with those followed in the preparation of the Group's annual consolidated financial statements for the year ended 31 December 2025 as disclosed in the Annual Report, except as described below and for the adoption of new standards and interpretations effective as of 01 January 2026, which are described in more details below. The condensed consolidated interim financial statements have been prepared on the historical cost basis, except forderivative financial instruments that are measured at fair values at the end of each reporting period. Historical cost isgenerally based on the fair value of the consideration given in exchange for assets. The Group as a lessor At inception or on modification of a contract that contains a lease component, the Group allocates the consideration in thecontract to each lease component on the basis of their relative standalone prices. When the Group acts as a lessor, it determines at lease inception whether each lease is a finance lease or an operating lease. To classify each lease, the Group makes an overall assessment of whether the lease transfers substantially all of therisks and rewards incidental to ownership of the underlying asset. If this is the case, then the lease is a finance lease;if not, then it is an operating lease. As part of this assessment, the Group considers certain indicators such as whetherthe lease is for the major part of the economic life of the asset. When the Group is an intermediate lessor, it accounts for its interests in the head lease and the sub‑lease separately.It assesses the lease classification of a sub‑lease with reference to the right‑of‑use asset arising from the head lease,not with reference to the underlying asset. If a head lease is a short‑term lease to which the Group applies the exemption described above, then it classifies the sub‑lease as an operating lease.
Page 13
The Group's contracts with clients contain an underlying lease component separate to the service element. Where alease is classified as an operating lease, the related lease income is recognised on a straight-line basis over the leaseterm. Where a lease is classified as a finance lease, the present value of the lease payments receivable is recognisedas a net investment in the lease within the consolidated condensed statement of financial position, and the relatedfinance income is recognised over the lease term in the consolidated condensed statement of comprehensiveincome. The Group applies the derecognition and impairment requirements in IFRS 9 to the net investment in thelease receivables. The Group applies IFRS 15 to allocate consideration under each component based on its standalone selling price. Thestandalone selling price of the lease component is estimated using a market assessment approach by taking themarket rate, being the contract day rate and deducting all other identifiable components, creating a residual amountdeemed to be the lease element. Adjusting items Adjusting items are significant items of income or expense in revenue, cost of sales, general and administrativeexpenses, other income, finance income and taxation, which individually or, if of a similar type, in aggregate, arerelevant to an understanding of the Group's underlying financial performance because of their size, nature orincidence. Adjusting items together with an explanation as to why management consider them appropriate to adjustare disclosed separately in Note 5. The Group believes that these items are useful to users of the Group's condensedconsolidated interim financial statements in helping them to understand the underlying business performancethrough Alternative Performance Measures that are used to derive the Group's principal non-GAAP measures ofadjusted Revenue, adjusted Earnings Before Interest, Taxes, Depreciation, and Amortisation ("EBITDA"), adjustedEBITDA margin, adjusted gross profit/(loss), adjusted operating profit/(loss), adjusted net profit/(loss) and adjusteddiluted earnings/(loss) per share, all of which are before the impact of adjusting items and which are reconciled fromoperating profit/(loss), profit/(loss) before taxation, net profit/(loss) and diluted earnings/(loss) per share. Adjustingitems include but are not limited to reversal of impairment / (impairment charges), impact of finance leaseaccounting related to a leased vessel, exceptional legal and tax costs, and non-operational finance-related costs. Basis of preparation The annual consolidated financial statements of the Group will be prepared in accordance with UK adoptedInternational Accounting Standards in conformity with requirements of the Companies Act 2006. The interim set ofcondensed consolidated financial statements included in this half-yearly financial report has been prepared inaccordance with the Disclosure Guidance and Transparency Rules of the Financial Conduct Authority and withInternational Accounting Standard (IAS) 34 Interim Financial Reporting as adopted by the United Kingdom. The condensed consolidated interim financial statements do not include all the information required for full annual consolidated financial statements and should be read in conjunction with the Group's audited consolidated financial statements for the year ended 31 December 2025. In addition, results for the six-month period ended 30 June 2026 are not necessarily indicative of the results that may be expected for the financial year ending 31 December 2026. The condensed consolidated statement of comprehensive income for the six-month period ended 30 June 2026 is not affected significantly by seasonality of results. Going concern The Directors have assessed the Group's financial position through to December 2027 and hold a reasonable expectation of its ability to continue as a going concern for the foreseeable future. The Group has a US$ 300.0 million loan facility (comprising a US$ 250.0 million term loan amortised over five years and a US$ 50.0 million working capital facility), denominated in United Arab Emirates Dirhams (AED) with a syndicate of three banks. The working capital facility includes a cash commitment of US$ 20.0 million, but if no cash is drawn, the full facility remains available for performance bonds and guarantees. The working capital facility expires alongside the main debt facility in December 2029. The three banks have an equal participation in the term loan and in the working capital facility. Entire cash commitment under the working capital facility remains unutilised. The interest rate is based on EIBOR plus a margin, which is determined by a ratchet depending on leverage levels. During the period, the Group obtained an additional US$ 37.4 million interim loan facility, to partially finance the acquisition of a new mid-class vessel, provided by a bank that is part of the Company's existing lending syndicate. Following the period end, the interim loan facility was included within the Company's existing lending arrangements, with the same syndicate of lenders and on the same commercial terms. The additional facility will be settled in 20 quarterly instalments over five years starting September 2026. Further, to support its growing operations, the Group also secured an additional AED ‐ equivalent US$ 7.5 million working capital facility from one of the banks in its lending syndicate. The working capital facility includes a cash commitment of US$ 3.0 million, but if no cash is drawn, the full facility remains available for performance bonds and guarantees. Entire working capital facility remains unutilised at the period end. Refer note 17 for outstanding term loan. The ongoing geopolitical situation in the Gulf region has continued to evolve and impact global energy markets during the reporting period. While diplomatic efforts have resulted in periods of reduced tensions, the situation remains fragile and unpredictable, with further episodes of escalation during and after the reporting period, and repeated disruption to shipping through the Strait of Hormuz resulting in continued volatility in oil and gas markets and further disruption to the Group's offshore operations. During early March, management was instructed to evacuate four vessels in one of the countries affected by the war in the Gulf, as a precautionary measure. All these vessels were back on hire on the same contracts by middle of June.
Page 14
As the geopolitical risks are still on-going, management continues to closely monitor developments, with a focus on safety of assets (including human capital), maintaining operational continuity, cost discipline and client engagement to mitigate potential disruptions. Proactive measures implemented since the previous reporting date continue to be applied to address any immediate effects, while contingency plans continue to be developed and refined to respond to more prolonged or renewed escalation scenarios, should the conflict persist or reignite. In the event of a sustained or further escalating situation, management will continue to reassess the potential implications and implement appropriate mitigating actions, including but not limited to engagement with lenders, where necessary. While elevated oil and gas prices driven by the ongoing geopolitical situation are expected to support continued focus on production resilience and capacity maintenance, operational disruptions during the period have weighed on activity levels and utilisation. Accordingly, the overall impact remains dependent on the timing of the resolution of the ongoing conflict. The management's forecast reflects key assumptions including those around vessel utilisation and day rates, on a vessel-by-vessel basis in light of the ongoing geopolitical situation in the Gulf region. Specifically, these assumptions are: - Two of the small class vessels remaining off hire until the end of 2026. - The utilisation for the 18-month assessment period to 31 Dec 2027 is forecasted at 91%. - Pipeline of tenders and opportunities for new contracts that would commence during the forecast period, subject to the timing of resolution of the ongoing geopolitical situation. A downside case was prepared using the following assumptions: - The geopolitical situation is assumed to escalate, resulting in operational disruption from 01 October 2026 to until 31 December 2026 and affecting all vessels operating across the Gulf region. - The forecast utilisation for the 18-month assessment period to 31 Dec 2027 falls to 80%, compared to a fleet average of 91% assumed in the base case cash flow forecasts for this period. The downside case is considered to be severe, but it would still leave the Group with sufficient liquidity and in compliance with the covenants under the Group's banking facilities throughout the assessment period. In addition to the above downside sensitivity, a reverse stress test is also performed by incorporating additional stress to the downside case above demonstrating a scenario to identify how much revenue and EBITDA reduction would result in a breach of covenants. The additional stress assumes a further extension of the operational disruption affecting the Group's vessels in the Gulf region from 1 January 2027 to 28 February 2027, resulting in an aggregate five-month off-hire period for all vessels operating in the Gulf region. This reduces utilisation for the 18-month assessment period to 72%, compared with 91% in the base case. Under this scenario, liquidity headroom is expected to reduce significantly in March 2027, followed by a liquidity shortfall in April 2027. The Group acknowledges the uncertainties stemming from the duration and the severity of the geopolitical situation and its impact on the Group's operations, as described above. Under certain circumstances they could result in the Group being in the above reverse stress tested scenario. After careful consideration of all the factors available to the Group at this time, including information from its clients and their plans, and having regard to developments during the period and up to the date of approval of these condensed consolidated interim financial statements, the Directors have concluded that the likelihood of the reverse stress scenario remains sufficiently low to not result in a material uncertainty that may cast significant doubt on the Group's ability to continue as a going concern. Should circumstances arise that differ from the Group's projections, the Directors believe that a number of mitigating actions can be successfully executed in the necessary timeframe to meet debt repayment obligations as they become due and in order to maintain liquidity. Potential mitigating actions include vessels off hire for prolonged periods being cold stacked to minimise the operating costs on these vessels, reduction in overhead costs, seeking relaxation/waiver from covenant compliance and rescheduling of repayments with lenders. The Directors continue to monitor, and where necessary refine, these mitigating actions in light of developments in the geopolitical situation described above and their evolving impact on the Group's operations and cash flows. After considering reasonable risks and potential downsides in light of the ongoing geopolitical situation in the Gulf region, including the developments during the period and up to the date of approval of these condensed consolidated interim financial statements, the Group's forecasts suggest that its bank facilities, combined with secured backlog and a pipeline of near-term opportunities for additional work, will provide sufficient liquidity to meet its needs in the foreseeable future, subject to the timing of resolution of the geopolitical situation. Accordingly, the condensed consolidated interim financial statements of the Group for the six-month period ended 30 June 2026 have been prepared on a going concern basis. New and amended standards adopted by the Group The following new and revised IFRSs have been adopted in these condensed consolidated interim financial statements.

Page 15
Amendments IFRS 9 and IFRS 7 regarding the contracts referencing nature-dependent electricity 1 January 2026 Annual Improvements to IFRS Accounting Standards - Volume 11 1 January 2026 The application of these new and revised IFRSs has not had any material impact on the amounts reported for the current and prior periods and did not require any retrospective adjustments but may affect the accounting for future transactions or arrangements. The full revised accounting policies applicable from 1 January 2026 will be provided in the Group's annual consolidated financial statements for the year ending 31 December 2026. At the date of the condensed consolidated interim financial statements, the following other standards, amendments and Interpretations have not been effective and have not been early adopted by the Group: New accounting standards or amendments Effective date - IFRS 18 Presentation and Disclosures in Financial Statements IFRS 18 will replace IAS 1 for reporting periods commencing on or after 1 January 2027. The following key changes will apply; · All income and expenses in the statement of profit or loss will be presented under five categories, namely operating, investing, financing, discontinued operations and income tax categories. · Operating profit will be defined as a residual capturing all income and expenses not classified as investing or financing items. · The operating profit line will be the start of the cash flow statement. · Additional disclosures will be included in the accounts on management defined performance measures. · Enhanced guidance is provided on how to group items in the primary financial statements and the notes. The Group is still assessing the impact of the new standard with respect to the structure of the income statement and how information is grouped in the financial statements including items labelled as other. 1 January 2027 - IFRS 19 Subsidiaries without Public Accountability: Disclosures 1 January 2027 - Amendments to IFRS 10 and IAS 28 Sale or Contribution of Assets between an Investor and its Associate or Joint Venture Available for optional adoption / effective date deferred indefinitely Management anticipates that these new standards, interpretations and amendments will be adopted in the Group's condensed consolidated interim financial statements as and when they are applicable and the impact of adoption of these new standards, interpretations and amendments is currently being assessed on the condensed consolidated interim financial statements of the Group before the period of initial application. 3 Key sources of Estimation Uncertainty and Critical Accounting Judgements In preparing these condensed consolidated interim financial statements, management has made judgements andestimates that affect the application of accounting policies and the reported amounts of assets and liabilities, incomeand expense. Actual results may differ from these estimates. The significant judgements made by management in applying the Group's accounting policies and the key sources ofestimation uncertainty include the impairment and reversal of previous impairment of property and equipment, taxprovision and impairment of financial assets as described in the last annual consolidated financial statements. Thelevel of uncertainty in the key estimates and judgment for recoverable amount for vessels has increased due to thecurrent regional geopolitical instability refer note 10. 4 Segment reporting The segment information provided to the chief operating decision makers for the operating and reportable segments for the period include the following: Revenue Gross profit before adjustments for depreciation, amortisation and impairment charges 6 months ended 30 June 6 months ended 30 June 2026 2025 2026 2025 US$'000 US$'000 US$'000 US$'000 K-Class vessels 20,920 26,109 8,801 14,167 S-Class vessels 21,786 22,755 15,925 16,973 E-Class vessels 36,778 38,202 22,219 26,462 Total 79,484 87,066 46,945 57,602 Less: Depreciation charged to cost of sales (17,906) (18,404) Amortisation charged to cost of sales (4,216) (3,680) Expected credit losses - net of recoveries (58) 343 Adjusted gross profit 24,765 35,861 Impairment loss on non-financial assets (22,741) -

Tax is calculated at the rates prevailing in the respective jurisdictions in which the Group operates. The overall effective rate is the aggregate of taxes paid in jurisdictions where income is subject to tax (being principally Qatar, the United Kingdom, Saudi Arabia and United Arab Emirates), divided by the Group's profit. 30 June 2026US$'000 30 June 2025US$'000 (Loss) / profit from operations before tax (12,273) 16,802 Tax at the UK corporation tax rate of 25% (2025: 25%) (3,068) 4,201 Effect of different tax rates in overseas jurisdictions 1,805 (579) Expense not deductible for tax purposes 228 (199) Overseas taxes 1,288 400 Increase in unrecognised deferred tax 412 1,484 Change in estimates of tax provisions 1,044 11,528 Loss / (income) not taxable for tax purposes 843 (3,978) Total tax charge 2,552 12,857 The Group's effective tax rate was (20.8%) for the period ended June 2026 (Six months ended June 2025: 76.5%). The current tax charge of US$ 2.6 million (six-month period ended June 2025: US$ 12.9 million) included withholding tax amounting to US$ 1.2 million (six-month period ended June 2025: US$ 0.7 million) and US$ 1.0 million (six-month period ended June 2025: US$ 11.5 million) related to change in estimates for prior years. On 9 December 2022, the UAE Ministry of Finance released Federal Decree-Law No. 47 of 2022 on the Taxation of Corporations and Businesses (Corporate Tax Law or the Law) to enact a Federal Corporate Tax regime in the UAE. This Law has become effective for accounting periods beginning on or after 1 June 2023. The Group's UAE operations is subject to a 9% corporation tax rate with effect from 01 January 2024. A rate of 0% apply to taxable income not exceeding AED 375,000. GMS has considered deferred tax implications in the preparation of these condensed consolidated interim financial statements in respect of property and equipment and potential timing differences that could give rise to a deferred tax liability. There are currently no UAE tax laws that would impact treatment of depreciation and amortization of property and equipment, that would result in such a timing difference. Hence, management has concluded that no adjustments to these condensed consolidated interim financial statements are necessary. 7 (Loss) / earnings per share 6 months ended 30 June 2026 6 months ended 30 June 2025 (Loss) / earnings for the purpose of calculating the basic and diluted (loss) / earnings per share being (loss) / profit for the period attributable to Owners of the Company (US$'000) (14,854) 3,849 Earnings for the purpose of calculating the adjusted basic and diluted profit per share (US$'000) (Note 5) 6,874 13,984 Weighted average number of shares ('000) 1,152,166 1,110,462 Weighted average diluted number of shares ('000) 1,161,044 1,140,943 Basic (loss) / earnings per share (cents) (1.29) 0.35 Diluted (loss) / earnings per share (cents) (1.29) 0.34 Adjusted earnings per share1 (cents) 0.60 1.26 Adjusted diluted earnings per share1 (cents) 0.59 1.23 Basic (loss) / earnings per share is calculated by dividing the (loss) / earnings attributable to equity holders of the Company for the period (as disclosed in the condensed consolidated statement of comprehensive income) by the weighted average number of ordinary shares in issue during the period. Adjusted earnings per share is calculated on the same basis as basic earnings but uses the adjusted profit attributable to equity holders of the Company for the period (refer Note 5). The adjusted earnings per share is presented as the Directors consider it provides an additional indication of the underlying performance of the Group. Diluted (loss) / earnings per share is calculated by dividing the (loss) / earnings attributable to owners of the Company for the period by the weighted average number of ordinary shares in issue during the period adjusted for the weighted average effect of warrants, long term incentive plan and deferred share bonus plan outstanding during the period. As at 30 June 2026, the effect of these adjustments are anti-dilutive, therefore, both basic and dilutive loss per share is same. Adjusted diluted earnings per share is calculated on the same basis but uses adjusted profit (refer Note 5) attributable to the equity shareholders of the Company.

Such indicators can befrom either internal or external sources. In circumstances in which any indicators of impairment or impairmentreversal are identified, the Group performs a formal impairment assessment to evaluate the carrying amounts of theGroup's vessels and their related assets, by comparing against the recoverable amount to identify any impairments orreversals. The recoverable amount is the higher of the vessels and related assets' fair value less costs to sell and valuein use. The Group's fleet was subject to impairment assessments during fiscal years 2019 to 2025. Based on the impairmentassessment reviews conducted in previous years, the Group recognised impairment losses and partial reversal ofthose impairment losses. As at 30 June 2026, and in line with IAS 36 requirements, management concluded that a formal impairmentassessment was required. Factors considered by management included increase in discount rate and ongoinggeopolitical conflict in the Gulf region. The conflict has resulted in short-term disruption and changes in deploymentplans. The impairment assessment as at 31 December 2025 had been conducted without incorporating the impact ofthe ongoing geopolitical situation in the Gulf region, as it was treated as a non-adjusting subsequent event for 2025consolidated financial statements. At each yearend, the Group obtains an independent valuation of its vessels for the purpose of its banking covenantcompliance requirements. However, consistent with prior years, management does not consider these valuations torepresent a reliable estimate of the fair value for the purpose of assessing the recoverable value of the Group'svessels, noting that there have been limited, if any, "willing buyer and willing seller" transactions of similar vessels inthe current offshore vessel market on which such values could reliably be based. Due to these inherent limitations,management has again concluded that recoverable amount should be based on value in use. The impairment review was performed for each cash-generating unit, by identifying the value in use of each vesseland of spares fittings, capitalised dry-docking expenditure, capital work in progress and right-of-use assets relating tooperating equipment used on the fleet, based on management's projections of future utilisation, day rates andassociated cash flows. The projection of cash flows related to vessels and their related assets is complex and requires the use of a numberof estimates, the primary ones being future day rates, vessel utilisation and discount rate. In estimating the value in use, management estimated the future cash inflows and outflows to be derived fromcontinuing use of each vessel and its related assets for the next three and half years based on its latest forecasts. Theterminal value cash flows (i.e., those beyond the 3.5-year period) were estimated based on historic mid-cycle dayrates and utilisation levels calculated by looking back as far as 2014, when the market was at the top of the cyclethrough to 2022 levels as the industry starts to emerge out of the bottom of the cycle, adjusted for anomalies. Theterminal value cash flow assumptions are applied until the end of the estimated useful economic life of each vessel,which is consistent with the prior year. Such long-term forecasts also take account of the outlook for each vessel
Page 20
having regard to their specifications relative to expected customer requirements and about broader long-term trendsincluding climate change. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-taxdiscount rate. The discount rate of 11.06% (31 December 2025: 10.85%) is computed on the basis of the Group'sweighted average cost of capital. The cost of equity incorporated in the computation of the discount rate is based onthe industry sector average betas, risk-free rate of return as well as Group specific risk premium reflecting anyadditional risk factors relevant to the Group. The cost of debt is based on the Group's actual cost of debt and theeffective cost of debt reported by the peer group as at 30 June 2026. The weighted average is computed based on theindustry capital structure. The impairment review led to the recognition of impairment of US$ 22.7 million (31 December 2025: net impairmentof US$ 7.5 million). The key reason for the impairment reflects a combination of a decrease in projected future cashflows operational disruptions due to the geopolitical conflict in the Gulf region, and increase in the discount rate from10.85% to 11.06%, predominantly driven by increase in both cost of debt and equity of the Group. In accordance with the Companies Act 2006, section 841(4), the following has been considered: a) the Directors have considered the value of some/all of the fixed assets of the Group without revaluing them;and b) the Directors are satisfied that the aggregate value of those assets are not less than the aggregate amount atwhich they were stated in the Group's accounts.

When reviewing the longer-term assumptions,the Group has continued to assume a lower day rate and utilisation for terminal values to reflect higher competitionin the market for smaller vessels. Key assumption sensitivities
Page 21
The Group has conducted an analysis of the sensitivity of the impairment test to reasonable possible changes in thekey assumptions (long-term day rates, utilisation and pre-tax discount rates) used to determine the recoverableamount for each vessel as follows: Day rates Day rates higher by 10% Day rates lower by 10% Vessels class Impact (in US$ million) Number of vessels impacted Impact (in US$ million) Number of vessels impacted (Impairment)/ impairment reversal of* (Impairment)/ impairment reversal of* E-Class CGUs 11.9 1.0 (25.0) 4.0 S-Class CGUs - - (4.4) 1.0 K-Class CGUs (2.7) 5.0 (47.3) 6.0 Total fleet 9.1 6.0 (76.7) 11.0 *This reversal of impairment / (impairment charge) is calculated on carrying values before the adjustment for impairment in 2026. There would be incremental impairment reversal of US$ 31.9 million and impairment charge of US$ 53.9 million forthe 10% increase and decrease in day rates assumption respectively. There would be no additional effect ofimpairment charge on corporate assets under the day rates sensitivity. The total recoverable amounts of the Group's vessels as at 30 June 2026 would have been US$ 840.3 million underthe increased day rates sensitivity and US$ 584.4 million for the reduced day rate sensitivity. Utilisation Utilisation higher by 10% Utilisation lower by 10% Vessels class Impact (in US$ million) Number of vessels impacted Impact (in US$ million) Number of vessels impacted (Impairment)/ impairment reversal of* (Impairment)/ impairment reversal of* E-Class CGUs 7.6 1.0 (25.0) 4.0 S-Class CGUs - - (4.4) 1.0 K-Class CGUs (3.8) 5.0 (47.3) 6.0 Total fleet 3.8 6.0 (76.7) 11.0 *This reversal of impairment / (impairment charge) is calculated on carrying values before the adjustment for impairment in 2026. There would be incremental impairment reversal of US$ 26.6 million and impairment charge of US$ 53.9 million forthe 10% increase and decrease in utilisation assumption respectively. There would be no additional effect ofimpairment charge on corporate assets under the utilisation sensitivity. The total recoverable amounts of the Group's vessels as at 30 June 2026 would have been US$ 798.5 million underthe increased utilisation sensitivity and US$ 584.4 million for the reduced utilisation sensitivity. Management would not expect an assumption change of more than 10% across all vessels within the next financialyear, and accordingly, believes that a 10% sensitivity to day rates and utilisation is appropriate. Discount rate An additional sensitivity analysis was conducted by adjusting the pre-tax discount rate upwards and downwards by100 basis points (1%). Given that the change in the discount rate from the previous year is less than 100 basis points,such sensitivity was deemed appropriate for this analysis. Discount rate higher by 1% Discount rate lower by 1% Vessels class Impact (in US$ million) Number of vessels impacted Impact (in US$ million) Number of vessels impacted (Impairment)/ impairment reversal of* (Impairment)/ impairment reversal of* E-Class CGUs (5.4) 1.0 2.8 1.0 S-Class CGUs - - - - K-Class CGUs (25.9) 6.0 (18.9) 5.0 Total fleet (31.3) 7.0 (16.1) 6.0 *This (impairment charge) / impairment reversal is calculated on carrying values before the adjustment for impairment in 2026. There would be incremental impairment charge of US$ 8.6 million and impairment reversal of US$ 6.7 million for the10% increase and decrease in pre-tax discount rate assumption respectively. The total recoverable amounts of the vessels as at 30 June 2026 would have been US$ 762.7 million under thereduced discount rate sensitivity and US$ 667.7 million for the increased discount rate sensitivity.

The previously recognised share capital balance relating to the old 10p ordinary shares was allocated pro rata to the new subdivided 2p ordinary shares and 8p deferred shares. The deferred shares had no voting rights and no right to the profits generated by the Group. On winding-up or other return of capital, the holders of deferred shares had extremely limited rights, if any. The Group had the right but not the obligation to buyback all of the deferred shares for an amount not exceeding £1.00 in aggregate, which with the shareholders approval, was completed on 30 June 2022. Accordingly, 350,487,787 deferred shares were cancelled. Following the cancellation of the Deferred shares on 30 June 2022, a transfer of $46.4 million was made from Share capital - Deferred to a Capital redemption reserve. There was no dilution to the shares ownership as a result of the share reorganisation. Under the Companies Act, a share buy‑back by a public company can only be financed through distributable reserves or the proceeds of a fresh issue of shares made for the purpose of financing a share buyback. The Company had sufficient reserves to purchase the Deferred shares for £1.00. 16 Capital redemption reserve The capital redemption reserve with a value of US$ 46.4 million was created on 30 June 2022 when the Company purchased and then cancelled 350,487,787 deferred ordinary shares (refer Note 15). The capital redemption reserve is not distributable. 17 Bank borrowings Secured borrowings at amortised cost are as follows: 30 June 2026 US$'000 31 December 2025 US$'000 Term loans 164,351 184,351 Bridge facility 37,400 - Less: Unamortised issue costs (4,374) (4,130) 197,377 180,221 30 June 2026 US$'000 31 December 2025 US$'000 At 1 January 184,351 241,189 Repayment of bank borrowings (20,000) (56,838) Additional bank borrowings 37,400 - Unamortised issue costs incurred (5,090) (5,167) Amortisation of issue costs 716 1,037 At period / year end 197,377 180,221 Bank borrowings are presented in the condensed consolidated interim financial position as follows: 30 June 2026 US$'000 31 December 2025 US$'000 Non-current Bank borrowings 121,804 142,224

Current Bank borrowings - scheduled repayments within one year 75,573 37,997 197,377 180,221 On 30 December 2024, the Group completed the refinancing of its existing bank borrowings. The purpose of therefinancing was primarily to settle in full all the amounts outstanding under the previous debt facility (which was scheduled to mature on 30 June 2025) as well as to fund the fees and expenses in relation to this transaction. The principal terms of the outstanding facility are as follows: · The facility is denominated in UAE Dirhams (AED) and consist of a term loan of AED 924.0 million (US$ 250.0 million) and working capital facility of AED 177.5 million (US$ 50.0 million). · The term loan will have a tenor of five years, where 80% of the term loan is payable in 19 equal quarterly instalments and the remaining 20% is payable on maturity. · The term loan carries floating rate linked to Emirates Interbank Offered Rate (EIBOR) plus a margin based on a ratchet depending on the Group's leverage level. · The working capital facility includes a cash commitment of US$ 20.0 million, but if no cash is drawn, the full facility remains available for performance bonds and guarantees. The working capital facility expires alongside the main debt facility in December 2029. · The facility is secured by mortgage of 13 vessels owned by the Group with a net book value of US$ 547.6 million, including the assignment of trade receivables amounting to US$ 31.6 million, bank balance amounting to US$ 16.4 million and insurance proceeds. · The facility is subject to certain financial covenants such as Interest Cover, Debt Service Cover, Gearing Ratio and Senior Net Leverage which are to be tested every six months. The financial covenant related to Security Cover is tested annually. All applicable financial covenants under the Group's debt facility were met as of 30 June 2026 and are expected to be compliant in the next 12 months from the approval of these condensed consolidated interim financial statements. During the period, the Group obtained US$ 37.4 million interim loan facility, to partially finance the acquisition of a newmid-class vessel, provided by a bank that is part of the Group's existing lending syndicate. Following the period end, the interim loan facility is converted within the Company's existing lending arrangements, withthe same syndicate of lenders and on the same commercial terms. The additional facility will be settled in 20 quarterly instalments over five years starting September 2026. Further, to support its growing operations, the Group also secured an additional AED ‐ equivalent US$7.5 million working capital facility from one of the banks in its lending syndicate. The working capital facility includes a cash commitment ofUS$ 3.0 million, but if no cash is drawn, the full facility remains available for performance bonds and guarantees. The Group is exposed to cash flow interest rate risk on its bank borrowings. The Group enters into floating interest rateinstruments for the same. Further, the Group has entered into an IRS to partially hedge its exposure. The IRS hedges therisk of variability in interest payments by converting a floating rate liability to a fixed rate liability. Refer Note 18 for more details. If interest rates had been 100 basis points higher/lower and all other variables were held constant, the profit for the period ended 30 June 2026 would decrease/increase by US$ 1.0 million (six-month period ended June 2025: US$ 1.1 million). This is mainly attributable to the Group's exposure to interest rates on its variable rate borrowings. Carrying amount of borrowings approximates their fair value at the period end. 18 Derivative financial instruments Warrants Under the terms of the Group's old loan facility, the Group was required to issue warrants to its lenders as GMS hadnot raised US$ 50.0 million of equity by 31 December 2022. On 2 January 2023, as the US$ 50.0 million equity raise did not take place, therefore 87,621,947 warrants wereissued to the lenders. Based on the final report prepared by a Calculation Agent, the warrants give right to theirholders to acquire 137,075,773 shares at an exercise price of 5.75 pence per share for a total consideration of GBP£7.9 million. Warrant holders had the right to exercise their warrants up to the end of the term of the loan facility,being 30 June 2025. During 2025, 52,556,697 warrants were exercised by the holders resulting in issuance of 82,219,697 new ordinaryshares with a nominal value of 2p per share and share premium of 3.75p per share. The fair value of the warrantsthat were exercised was recalculated at the time of exercise. The fair value of warrant exercised was calculated at
Page 25
US$ 13.3 million. This fair value is added to the actual cash raised of US$ 6.1 million, in line with Companies Act2006 to give a total increase in share capital and share premium of US$ 19.4 million. No issue cost paid. Sharesissued as a result of the exercise of warrants were ordinary shares with identical rights and privileges as the existingshares of the Group. On the expiry date of the warrants, i.e. 30 June 2025, 846,550 warrants remained unexercised. These were derecognised and the related fair value of US$ 0.1 million was recognised in profit or loss during that year. Interest Rate Swap (IRS) The Group entered into an IRS during 2025 to partially hedge its variable interest risk exposure. The notional amountunder the IRS is AED 106.9 million (US$ 29.2 million) (31 December 2025: AED 120.0 million (US$ 32.7 million))reducing over the term of the IRS on a quarterly basis, maturing on 31 December 2027. Further, during the year theGroup entered into another IRS to further hedge its variable interest risk exposure. The notional amount under thenew IRS is AED 208.8 million (US$ 57.0 million) reducing over the term of the IRS on a quarterly basis, maturing on23 March 2028. As at 30 June 2026, the notional amount of this IRS is AED 196.7 million (US$ 53.7 million). The fairvalue of the IRS contracts as at 30 June 2026 was an asset of US$ 0.2 million (31 December 2025: liability of US$ 0.1million). The unrealised gain for the period is US$ 0.3 million (2025: unrealised loss US$ 0.1 million) accordingly,recognised in the consolidated statement of profit or loss and other comprehensive income. Forward Foreign Exchange Contracts (FX contracts) The Group entered into FX contracts during 2025 to hedge its exposure for USD to AED fluctuations for therepayment of its Dirham-based term loan. The notional amount of FX contracts is AED 607.2 million (US$ 165.9million) (31 December 2025: AED 681.8 million (US$ 186.3 million)) reducing on a quarterly basis in line with thequarterly principal repayments due on the term loan, maturing on 31 December 2029. The fair value of the contractas at 30 June 2026 was a liability of US$ 0.5 million (31 December 2025: US$ 0.5 million). The unrealised gain for theperiod is US$ 0.1 million (2025: unrealised loss US$ 0.5 million) accordingly, recognised in the consolidatedstatement of profit or loss and other comprehensive income.

The Group has IRS and FX contracts as financial instruments that are classified as Level 2 in the fair value hierarchy.The fair value of the Group's derivatives as at 30 June 2026 and 31 December 2025 has been arrived at on the basisof a valuation carried out by independent counterparty banks. Favourable and unfavourable changes in the value offinancial instruments are determined on the basis of changes in the value of the instruments as a result of varyingthe levels of the unobservable parameters, quantification of which is judgemental. There have been no transfersbetween Level 2 and Level 3 during the period ended 30 June 2026 and 31 December 2025. There are no non-recurring fair value measurements. 19 Contingent liabilities As at 30 June 2026, the banks acting for Gulf Marine Services FZE, one of the subsidiaries of the Group, had issuedperformance bonds amounting to US$ 26.6 million (31 December 2025: US$ 25.7 million), all of which werecounter-indemnified by other subsidiaries of the Group. 20 Capital commitments 30 June 2026 31 December 2025 US$'000 US$'000 Contractual capital commitments 5,093 16,043 Capital commitments comprise mainly capital expenditure, which has been contractually agreed with suppliers for future periods for equipment or the refurbishment of existing vessels. 21 Long term incentive plans Long term incentive plans (LTIPs) On 11 June 2025 and 15 May 2026, the Group has granted LTIPs to senior management. The LTIP awards will generally vest three years from the grant date, subject to the achievement of market vesting conditions aligned with shareholder interests. The maximum number of Company's shares under these LTIPs is 14,042,857. LTIP awards are not subject to a post-vesting holding period, except for those granted to the Executive Chairman, which have a two-year post-vesting holding period. Equity-settled share-based payments were measured at fair value at the date of grant. The fair value was determined, using the Monte Carlo simulation method, at the grant date of equity-settled share-based payments, is expensed on a straight-line basis over the vesting period, based on an estimate of the number of shares that will ultimately vest. The fair value of each award was determined by taking into account the performance conditions, the term of the award, the share price at grant date, the expected price volatility of the underlying share, post-vesting period and the risk-free interest rate for the term of the award. Deferred share bonus plan (DSBP) On the same dates LTIPs were awarded to senior management, the Group also granted its Executive Chairman DSBP awards. These awards, which are equivalent to a total of 569,135 shares of the Company, pertain to the relevant proportion of the Executive Chairman's previous years' annual bonuses deferred under the terms of the shareholder- approved Directors' Remuneration Policy. These shares will generally vest after two years from 1 January 2025 and 1 January 2026, respectively. The DSBP award is not subject to any market-based performance or service conditions, the fair value of the award is considered to be the closing share price as at the date of grant. The number of share awards granted by the Group during the period/year is given in the table below: 30 June 2026 31 December 2025 No. of LTIPs No. of DSBP No. of LTIPs No. of DSBP At beginning of the year 6,595,292 271,403 - - Granted during the period 7,447,565 297,732 6,595,292 271,403 At the end of the period 14,042,857 569,135 6,595,292 271,403 The total expense recognised during the period with respect to LTIPs and DSBP amounted to US$ 372k (30 June 2025: US$ 88k).

A 10% discount for lack of marketability was applied to reflect lower liquidity compared to if the awards were not subject to a holding period. 22 Related party transactions Transactions with related parties during the period were as follows: 30 June 2026 US$'000 30 June 2025 US$'000 Emirates Insurance Company 1 24 Catering services for vessel Pepper from National Catering Company Limited WLL 10 - Laboratory services from Aman Integrated Solutions LLC 2 5 Related party balances included in trade and other payables are as follows: 30 June 2026 US$'000 31 December 2025 US$'000 Sigma Enterprise Company LLC 851 775 Aman Integrated Solutions LLC 7 4 Emirates Insurance Company 3 - National Catering Company Limited WLL 10 5 23 Events after the reporting period Subsequent to the period end, the Group: - Has converted its interim loan facility used to acquire a new vessel into a long ‐ term term loan within the Group's existing lending arrangements (Refer Note 17). - Has secured an additional AED ‐ equivalent US$ 7.5 million working capital facility, from one of the banks in its lending syndicate, to support its growing operations (Refer Note 17). 24 Glossary Alternative Performance Measure (APMs) - An APM is a financial measure of historical or future financial performance, financial position, or cash flows, other than a financial measure defined or specified in the applicable financial reporting framework. APMs are non-GAAP measures that are presented to provide readers with additional financial information that is regularly reviewed by management, and the Directors consider that they provide a useful indicator of underlying performance. Adjusted results are also an important measure providing useful information as they form the basis of calculations required for the Group's covenants. However, this additional information presented is not uniformly defined by all companies including those in the Group's industry. Accordingly, it may not be comparable with similarly titled measures and disclosures by other companies. Additionally, certain information presented is derived from amounts calculated in accordance with IFRS but is not itself an expressly permitted GAAP measure. Such measures should not be viewed in isolation or as an alternative to the equivalent GAAP measure. In response to the Guidelines on APMs issued by the European Securities and Markets Authority (ESMA), we have provided additional information on the APMs used by the Group. Adjusted earnings per share - represents the adjusted earnings attributable to equity holders of the Company for the period divided by the weighted average number of ordinary shares in issue during

the period. The adjusted earnings attributable to equity shareholders of the Company is used for the purpose of basic gain per share adjusted for any exceptional items. Adjusted diluted earnings per share - represents the adjusted earnings attributable to equity holders of the Company for the period divided by the weighted average number of ordinary shares in issue during the period, adjusted for the weighted average effect of share options outstanding during the period. The adjusted earnings attributable to equity shareholders of the Company is used for the purpose of basic gain per share adjusted by adding back impairment charges or writeback of impairment loss, and costs to acquire new bank facilities. This measure provides additional information regarding earnings per share attributable to the underlying activities of the business. A reconciliation of this measure is provided in Note 5 and 7. Adjusted revenue - represents revenue after removing the impact of finance lease accounting relating to a leased vessel.
