STRATEGIC REPORT FOR THE YEAR ENDED 31 DECEMBER 2025
Introduction
The directors present their Strategic Report for the year ended 31 December 2025.
Business review
Turnover has decreased by £6,209,000 to £66,929,000 (2024 - £73,138,000) during the year due to the decrease in demand for crewing services provided by the Company to its related parties. The Company has an operating profit of £361,000 for the year (2024 - £695,000). The decrease is due to reduced group vessel utilisation. No dividends have been paid and shareholder’s funds have increased by £273,000 (2024 - £533,000). The key financial and other performance indicators during the year are presented below:

STRATEGIC REPORT (CONTINUED) FOR THE YEAR ENDED 31 DECEMBER 2025
Principal risks and uncertainties
As a subsidiary company the principal risks and uncertainties of the Company are those that the parent undertaking is exposed to. The parent undertaking undertakes an annual management review of its performance and identifies those risks and issues that require to be mitigated and resolved to meet or exceed the Company’s year end qualitative and quantitative targets. The review sets performance indicators and objectives for the following year to mitigate risks that have threatened or have affected the Company performance across the previous year. The parent undertaking categorises risks into four main areas – Commercial, Technical, Contract and Financial. Commercial risk Commercial risk is loss of reputation from contract performance failure or negative publicity. These are documented within the parent undertaking management systems, and are updated as new risks are identified or market factors enable risks to be mitigated further. Technical risk Technical risk is probability of loss incurred through the execution of a technical process in which the outcome is uncertain. These are identified and assessed through a rigorous management programme and control measures are applied to reduce those risks to as low a level as reasonably practicable. The parent undertaking continually reviews standards, policies and operating practices to reduce risks further. Contract risk Contract risk is the probability of loss from contract performance, either by cancellation or substandard performance. This is mitigated through negotiation against standards for risk levels which are defined from industry best practice and many years of contracting experience. A formal internal process exists where only the senior management in the parent group has the right to authorise a departure from those standards. Financial risk Financial risk is the probability of loss through credit, liquidity and currency risks. Financial risk is monitored through comprehensive accounting practices and cash management, and through implementation of a structured empowerment matrix detailing the levels of authority within the tiers of the group organisation. Energy use and greenhouse gas emissions The company did not consume more than 40,000 kilowatt hours (kWh) of energy in the financial reporting year; and therefore it has not met the criteria to disclose information related to Energy use and Greenhouse gas emissions.

Directors' statement of compliance with duty to promote the success of the Company
The Directors recognise their duty to act in a way which they consider, in good faith, would be most likely to promote the success of the Company for the benefit of its members as a whole in accordance with section 172 of the UK Companies Act 2006. The Directors’ section 172 duties are part of Board discussions. The Directors continue to have regard to the interest of the Company’s key stakeholders and, throughout the year, the Board and management engage with key stakeholders on items relevant to them. We set out below our key stakeholder groups, their material issues and how the Company engages with and considers the interest of each stakeholder group. Investors and lenders The key areas of focus with regards to this stakeholder group is financial performance, strategy and capital allocation. Helix Offshore Crewing Services Limited commits to maximising long term shareholder value through clearly identifying risks, thorough planning and having effective internal controls in place. It is imperative that risks are understood and effectively managed to ensure that objectives are achieved. Although the Company has no external shareholders, the financial results are consolidated in the group results of the ultimate parent Company, Helix Energy Solutions Group, Inc. The group results are disclosed quarterly to the wider investor market, followed by a conference call with representatives from institutional shareholders to discuss group financial performance and strategy. Changes to the Company’s capital structure in order to optimise group liquidity or capital is ratified by the Company’s board of directors. Employees The key areas of focus with regards to this stakeholder group is engagement and work culture, training and development, diversity and inclusion and remuneration. The Company holds employee forums to communicate Company policy and initiatives. This provides an opportunity for senior management to engage with employees and answer questions that employees may have. The Company distributes employee satisfaction surveys and conducts exit interviews of employees leaving the organisation, all to gather feedback to further engagement with employees on work culture. The Company provides competitive compensation and benefit packages in addition to offering developmental opportunities based on individual performance and identified potential. The Company promotes a ‘speak up’ culture in the event ethical dilemmas arise. The Company has a zero tolerance policy for retaliation against employees who raise such concerns to senior management. Annual compliance training with regards to the UK Bribery Act (2010) and the US Foreign and Corrupt Practices Act (FCPA) is a mandatory requirement. The Company actively seeks to promote diversity and inclusion throughout its workforce. Page 3
HELIX OFFSHORE CREWING SERVICES LIMITED
STRATEGIC REPORT (CONTINUED) FOR THE YEAR ENDED 31 DECEMBER 2025 Suppliers The key areas of focus with regards to this stakeholder group is efficiency, expertise and enhancing relationships. The material element of cost of sales relates to employee’s who provide offshore services for the group companies, Helix Well Ops (U.K.) Limited and Helix Robotics Solutions Limited. External suppliers are used for the provision of logistical services, albeit an immaterial element of cost of sales. In accordance with the group anti corruption compliance policy, the Company embraces the highest standards of honesty, ethics and integrity as core business values, and will do business only by lawful and ethical means. We carefully select our external business partners through the application of rigorous due diligence processes, ensuring such business partners share our values and our commitment to safety and integrity. The Company strives to comply with its external supplier contracts, which in turn helps us create and maintain long term supplier relationships. Customers The key areas of focus with regards to this stakeholder group is efficiency, expertise and responsiveness. Customers are limited to internal group companies only, being Helix Well Ops (U.K.) Limited and Helix Robotics Solutions Limited. As there is no external customer base, there is no requirement for performance metrics to be reported regularly to the senior management and the Board. In addition, there is no requirement to conduct an extensive financial review on new clients. This report was approved by the board and signed on its behalf.

DIRECTORS' RESPONSIBILITIES STATEMENT FOR THE YEAR ENDED 31 DECEMBER 2025 The directors are responsible for preparing the Strategic Report, the Directors' Report and the financial statements in accordance with applicable law and regulations. Company law requires the directors to prepare financial statements for each financial year. Under that law the directors have elected to prepare the financial statements in accordance with applicable law and United Kingdom Accounting Standards (United Kingdom Generally Accepted Accounting Practice), including Financial Reporting Standard 101 ‘Reduced Disclosure Framework’. Under company law the directors must not approve the financial statements unless they are satisfied that they give a true and fair view of the state of affairs of the Company and of the profit or loss of the Company for that period. In preparing these financial statements, the directors are required to: ∙select suitable accounting policies and then apply them consistently; ∙make judgments and accounting estimates that are reasonable and prudent; ∙state whether applicable UK Accounting Standards have been followed, subject to any material departures disclosed and explained in the financial statements; ∙prepare the financial statements on the going concern basis unless it is inappropriate to presume that the Company will continue in business. The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the Company's transactions and disclose with reasonable accuracy at any time the financial position of the Company and to enable them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the Company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities. Page 6

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF HELIX OFFSHORE CREWING SERVICES LIMITED
Opinion
We have audited the financial statements of Helix Offshore Crewing Services Limited (the 'Company') for the year ended 31 December 2025, which comprise the Statement of Comprehensive Income, the Statement of Financial Position, the Statement of Changes in Equity and the related notes, including a summary of significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 101 ‘Reduced Disclosure Framework’ (United Kingdom Generally Accepted Accounting Practice). In our opinion the financial statements: ∙give a true and fair view of the state of the Company's affairs as at 31 December 2025 and of its profit for the year then ended; ∙have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and ∙have been prepared in accordance with the requirements of the Companies Act 2006.
Basis for opinion
We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards are further described in the Auditors' responsibilities for the audit of the financial statements section of our report. We are independent of the Company in accordance with the ethical requirements that are relevant to our audit of the financial statements in the United Kingdom, including the Financial Reporting Council's Ethical Standard and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.
Conclusions relating to going concern
In auditing the financial statements, we have concluded that the directors' use of the going concern basis of accounting in the preparation of the financial statements is appropriate. Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the Company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue. Our responsibilities and the responsibilities of the directors with respect to going concern are described in the relevant sections of this report.
Other information
The other information comprises the information included in the Annual Report other than the financial statements and our Auditors' Report thereon. The directors are responsible for the other information contained within the Annual Report. Our opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon. Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact. We have nothing to report in this regard.

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF HELIX OFFSHORE CREWING SERVICES LIMITED (CONTINUED)
Opinion on other matters prescribed by the Companies Act 2006
In our opinion, based on the work undertaken in the course of the audit: ∙the information given in the Strategic Report and the Directors' Report for the financial year for which the financial statements are prepared is consistent with the financial statements; and ∙the Strategic Report and the Directors' Report have been prepared in accordance with applicable legal requirements.
Matters on which we are required to report by exception
In the light of the knowledge and understanding of the Company and its environment obtained in the course of the audit, we have not identified material misstatements in the Strategic Report or the Directors' Report. We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion: ∙adequate accounting records have not been kept, or returns adequate for our audit have not been received from branches not visited by us; or ∙the financial statements are not in agreement with the accounting records and returns; or ∙certain disclosures of directors' remuneration specified by law are not made; or ∙we have not received all the information and explanations we require for our audit.
Responsibilities of directors
As explained more fully in the Directors' Responsibilities Statement set out on page 6, the directors are responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the directors determine is necessary to enable the preparation of financial statements that are free from material misstatement, whether due to fraud or error. In preparing the financial statements, the directors are responsible for assessing the Company's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the Company or to cease operations, or have no realistic alternative but to do so.

HELIX OFFSHORE CREWING SERVICES LIMITED
INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF HELIX OFFSHORE CREWING SERVICES LIMITED (CONTINUED)
Auditors' responsibilities for the audit of the financial statements
Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an Auditors' Report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with ISAs (UK) will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these financial statements. Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below: We considered the opportunities and incentives that may exist within the organisation for fraud and identified the greatest potential for fraud in the following areas: ∙timing and completeness of revenue recognition; ∙completeness and accuracy of payroll costs; ∙compliance with relevant laws and regulations which may impact on the financial statements and those that the company needs to comply with for the purpose of trading; ∙management judgements applied in calculating provisions; and ∙management override of controls to manipulate the Company's key performance indicators to meet targets. We discussed these risks with client management, designed audit procedures to address these risks including: ∙testing a sample of sales transactions to source documents and vouching recognition is in the correct period; ∙testing a sample of employee costs to source documentation and verifying existence of employees; ∙reviewed internal documentation and correspondence with regulators for evidence or irregularities; ∙consideration of the assumptions applied whether the judgements applied in calculation of provisions were appropriate; ∙reviewed areas of judgement and tested a sample of journal entries for indicators of management bias; and ∙performed analytical procedures to identify any unusual or unexpected relationships which may be an indication of material misstatement due to fraud. Because of the inherent limitations of an audit, there is a risk that we will not detect all irregularities, including those leading to a material misstatement in the financial statements or non-compliance with regulation. This risk increases the more that compliance with a law or regulation is removed from the events and transactions reflected in the financial statements, as we will be less likely to become aware of instances of non-compliance. The risk is also greater regarding irregularities occurring due to fraud rather than error, as fraud involves intentional concealment, forgery, collusion, omission or misrepresentation. A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council's website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our Auditors' Report. Page 9

NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 31 DECEMBER 2025
1. | General information
Helix Offshore Crewing Services Limited (the “Company”) is a private company incorporated, domiciled and registered in Scotland in the UK. The registered number is SC266314 and the registered address is 13 Queen's Road, Aberdeen, AB15 4YL. The financial statements are presented in Sterling, which is the functional currency, and are rounded to the nearest thousand pounds (£'000). 2.Accounting policies
| 2.1 | Basis of preparation of financial statements
The financial statements have been prepared under the historical cost convention unless otherwise specified within these accounting policies and in accordance with Financial Reporting Standard 101 'Reduced Disclosure Framework' and the Companies Act 2006. The preparation of financial statements in compliance with FRS 101 requires the use of certain critical accounting estimates. It also requires management to exercise judgment in applying the Company's accounting policies (see note 3). The following principal accounting policies have been applied:
| 2.2 | Financial Reporting Standard 101 - reduced disclosure exemptions
The Company has taken advantage of the following disclosure exemptions under FRS 101: ∙the requirements of IFRS 7 Financial Instruments: Disclosures ∙the requirements of IAS 7 Statement of Cash Flows ∙the requirements of paragraph 17 and 18A of IAS 24 Related Party Disclosures ∙the requirements of paragraphs 130(f)(ii), 130(f)(iii), 134(d)-134(f) and 135(c)-135(e) of IAS 36 Impairment of Assets.

HELIX OFFSHORE CREWING SERVICES LIMITED
NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 31 DECEMBER 2025 2.Accounting policies (continued)
| 2.3 | Going concern
The financial statements have been prepared on a going concern basis which the Directors consider to be appropriate for the following reasons. At the financial year end, the Company had net current assets of £1,596,000 (2024 - £1,323,000), cash balance of £849,000 (2024 - £819,000) and profit for the year then ended of £273,000 (2024 - £533,000). The Company has no external borrowings. The Company’s only customers are fellow group companies and it has, throughout this period, continued to offer HR, logistics and personnel services in line with its service agreements. As a result, the directors consider that the significant factor affecting their going concern assessment is that the Company does not have any external customers and it is dependent on the trading of its immediate parent company, Helix Well Ops (U.K.) Limited, and other fellow group subsidiaries within the Helix Energy Solutions Group, Inc ("the group"). These group subsidiaries trade with third party customers. The directors have considered the group subsidiaries' forecasts and projections for a period of at least 12 months from the date of these financial statements. These forecasts include severe but plausible downsides, in which revenues are restricted through lower levels of asset utilisation throughout the forecasted period. This assessment is dependent on the Company’s parent, Helix Energy Solutions Group Inc and its other subsidiary entities not seeking repayment of the amounts currently due to the group, which at 31 December 2025 amounted to £271,983. Helix Energy Solutions Group Inc has indicated that it does not intend to seek repayment of the amounts due at the balance sheet date, for the period covered by the forecasts. The directors have considered the financial position of the group and parent company, and they have considered that the parent company has the ability and intent to continue with this support. Consequently, the directors are confident that the Company will have sufficient funds to continue to meet its liabilities as they fall due for at least twelve months from the date of approval of the financial statements and therefore have prepared the financial statements on a going concern basis.
| 2.4 | Foreign currency translation
Functional and presentation currency The Company's functional and presentational currency is GBP. Transactions and balances Foreign currency transactions are translated into the functional currency using the spot exchange rates at the dates of the transactions. At each period end foreign currency monetary items are translated using the closing rate. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction and non-monetary items measured at fair value are measured using the exchange rate when fair value was determined.

| 2.5 | Revenue
Revenue is recognised to the extent that it is probable that the economic benefits will flow to the Company and the revenue can be reliably measured. Revenue is measured as the fair value of the consideration received or receivable, excluding discounts, rebates, value added tax and other sales taxes. The following criteria must also be met before revenue is recognised: Revenue from contracts with customers Revenue is recognised at an amount that reflects the consideration to which the Company is expected to be entitled in exchange for transferring goods or services to a customer. For each contract with a customer, the Company: ∙Identifies the contract with the customer ∙Identifies the separable performance obligations in the contract ∙Determines the overall transaction (contract) price, allowing for estimates of variable consideration and the time value of money ∙Allocates the transaction price across the separable performance obligations on the basis of the relative stand-alone selling prices of each distinct good or service to be delivered, applying any overall discounts across the entire contract (or on specific performance obligations if more appropriate). ∙Recognises revenue when, or as, each performance obligation is satisfied in a manner that reflects the transfer of control of the goods or services promised to the customer. The variable consideration within the transaction price, if any, reflects concessions provided to the customer such as discounts, rebates and refunds and any other contingent events. Such estimates are determined using the expected value method and are only recognised when they are highly probable. If any uncertainty exists with respect to a potential refund of the variable consideration received, this consideration is recognised as deferred revenue until the uncertainty is resolved. (i) Rendering of services The Company recognises revenue for service performance obligations over time as those services are fulfilled. The revenue will be based either on a fixed price or an hourly/day rate.
| 2.6 | Interest income
Interest income is recognised in profit or loss using the effective interest method.
| 2.7 | Finance costs
Finance costs are charged to profit or loss over the term of the debt using the effective interest method so that the amount charged is at a constant rate on the carrying amount. Issue costs are initially recognised as a reduction in the proceeds of the associated capital instrument. Page 16

| 2.8 | Pensions
Defined contribution pension plan The Company operates a defined contribution plan for its employees. A defined contribution plan is a pension plan under which the Company pays fixed contributions into a separate entity. Once the contributions have been paid the Company has no further payment obligations. The contributions are recognised as an expense in profit or loss when they fall due. Amounts not paid are shown in accruals as a liability in the Statement of Financial Position. The assets of the plan are held separately from the Company in independently administered funds.
| 2.9 | Current and deferred taxation
The tax expense for the year comprises current and deferred tax. Tax is recognised in profit or loss except that a charge attributable to an item of income and expense recognised as other comprehensive income or to an item recognised directly in equity is also recognised in other comprehensive income or directly in equity respectively. The current income tax charge is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the reporting date in the countries where the Company operates and generates income. Deferred tax balances are recognised in respect of all timing differences that have originated but not reversed by the reporting date, except that: ∙The recognition of deferred tax assets is limited to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits; and ∙Any deferred tax balances are reversed if and when all conditions for retaining associated tax allowances have been met. Deferred tax balances are not recognised in respect of permanent differences except in respect of business combinations, when deferred tax is recognised on the differences between the fair values of assets acquired and the future tax deductions available for them and the differences between the fair values of liabilities acquired and the amount that will be assessed for tax. Deferred tax is determined using tax rates and laws that have been enacted or substantively enacted by the reporting date.
| 2.10 | Debtors
Short-term debtors are measured at transaction price, less any impairment. Loans receivable are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method, less any impairment.
| 2.11 | Cash and cash equivalents
Cash is represented by cash in hand and deposits with financial institutions repayable without penalty on notice of not more than 24 hours. Cash equivalents are highly liquid investments that mature in no more than three months from the date of acquisition and that are readily convertible to known amounts of cash with insignificant risk of change in value.

| 2.12 | Creditors
Creditors are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Creditors are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method.
| 2.13 | Financial instruments
The Company recognises financial instruments when it becomes a party to the contractual arrangements of the instrument. Financial instruments are de-recognised when they are discharged or when the contractual terms expire. The Company's accounting policies in respect of financial instruments transactions are explained below: Financial assets and financial liabilities are initially measured at fair value. Financial assets All recognised financial assets are subsequently measured in their entirety at either fair value or amortised cost, depending on the classification of the financial assets. Fair value through profit or loss All of the Company's financial assets are subsequently measured at fair value at the end of each reporting period, with any fair value gains or losses being recognised in profit or loss to the extent they are not part of a designated hedging relationship. The net gain or loss recognised in profit or loss includes any dividend or interest earned on the financial asset. Impairment of financial assets The Company always recognises lifetime ECL for trade receivables and amounts due on contracts with customers. The expected credit losses on these financial assets are estimated based on the Company's historical credit loss experience, adjusted for factors that are specific to the debtors, general economic conditions and an assessment of both the current as well as the forecast direction of conditions at the reporting date, including time value of money where appropriate. Lifetime ECL represents the expected credit losses that will result from all possible default events over the expected life of a financial instrument. Financial liabilities Fair value through profit or loss Financial liabilities are classified as at fair value through profit or loss, when the financial liability is held for trading, or is designated as at fair value through profit or loss. This designation may be made if such designation eliminates or significantly reduces a measurement or recognition inconsistency that would otherwise arise, or the financial liability forms part of a group of financial instruments which is managed and its performance is evaluated on a fair value basis, or the financial liability forms part of a contract containing one or more embedded derivatives, and IFRS 9 permits the entire combined contract to be designated as at fair value through profit or loss. Any gains or losses arising on changes in fair value are recognised in profit or loss to the extent that they are not part of a designated hedging relationship. Page 18

| 2.13 | Financial instruments (continued)
At amortised cost Financial liabilities which are neither contingent consideration of an acquirer in a business combination, held for trading, nor designated as at fair value through profit or loss are subsequently measured at amortised cost using the effective interest method. This is a method of calculating the amortised cost of a financial liability and of allocating interest expense over the relevant period. The effective interest rate is the rate that exactly discounts estimated future cash payments through the expected life of the financial liability, or where appropriate a shorter period, to the amortised cost of a financial liability.
3. | Judgments in applying accounting policies and key sources of estimation uncertainty
The preparation of financial statements requires management to make judgements, estimates and assumptions that affect the amounts reported for assets and liabilities as at the balance sheet date and the amounts reported for revenues and expenses during the year. However, the nature of estimation means that actual outcomes could differ from those estimates. The following judgements apart from those involving estimates have had the most significant effect on amounts recognised in the financial statements: Recognition of service being rendered As described in the revenue recognition accounting policy, revenue is recognised when the significant risks and rewards of ownership have been transferred to the customer, it is probable that the economic benefits associated with a transaction will flow to the Company and the amount of revenue can be measured reliably. Informed judgement is required as and when logistical services take place, thus the timing of services being rendered.
4. | Turnover
The whole of the turnover is attributable to the rendering of services.
| Timing of revenue recognition:
|  |  |  | 2025 | 2024
|  |  |  | £000 | £000
| Rendering of services | 66,929 | 73,138
|  | 66,929 | 73,138
| Revenue refers entirely to Human Resource (HR), logistical support and provision of crewing personnel.
