Strategic Report

for the Year Ended 31 December 2025

The directors present their strategic report for the year ended 31 December 2025.

REVIEW OF BUSINESS AND OUTLOOK

Sirius Engineering Group is a design and build enabling works specialist delivering integrated consultancy, ground engineering and contracting services to the land development sector. Operating across the United Kingdom from regional offices in Durham, Leeds, Warrington and Llanelli, the Group provides services including demolition, earthworks, remediation, drilling and civil engineering, supported by a specialist plant and technologies division. The Group also provides geotechnical, environmental and planning consultancy services.

The Group's competitive advantage lies in its ability to provide a single integrated solution from initial investigation through to development readiness, often on a design and build basis. This enables clients to de-risk complex brownfield and greenfield sites and progress technically challenging developments with confidence.

Operating since 2003, Sirius has developed a stable repeat-business client base across several principal sectors including residential, commercial and retail development, waste management and renewable energy. In 2023, coinciding with its 20th anniversary, the Group transitioned to employee ownership, supporting long-term succession and aligning the future success of the business with the people who have helped to build it.

Sirius Civil Engineering Limited is a specialist civil engineering contractor operating within the Sirius Engineering Group. The Company specialises in the provision of primary infrastructure to new development sites, principally within the residential and commercial development sectors. This typically includes the installation of roads and sewers to adoptable standards, associated drainage infrastructure and the construction of retaining structures.

The ability to deliver primary infrastructure in combination with initial earthworks, remediation and wider enabling works is a key differentiator for the business, particularly when delivered alongside other Sirius Group companies. This integrated approach can assist clients in achieving cost and programme efficiencies, reducing interface risk and progressing sites from initial enabling works through to development-ready infrastructure.

The Company operates principally within the residential land development sector, whilst also supporting commercial, industrial and infrastructure-related projects. The Company continues to benefit from the wider Group's long-standing customer relationships, technical reputation and integrated design and build capability.

The results for the year and the financial position of the Company are set out on pages 9 to 18.

Strategic Report

for the Year Ended 31 December 2025

Financial Performance

The directors report a satisfactory financial performance for the year ended 31 December 2025. The Company delivered substantial growth in turnover and increased profitability, although margins continued to be affected by inflationary cost pressures and a competitive pricing environment across the sector.

Turnover increased to £29.1 million from £19.8 million in 2024, reflecting a significant uplift in roads, sewers, drainage and associated infrastructure works delivered during the year, across both residential and commercial sectors. Gross profit increased to £3.4 million, although gross margin reduced to approximately 11.9% compared with 13.0% in the prior year. Despite these margin pressures, profit before taxation increased to £1.0 million compared with £0.5 million in 2024.

As reported by the wider Group, improving market confidence during late 2024 contributed to a stronger operational pipeline heading into 2025. This momentum continued during the year and supported increased activity levels across the Company. The gradual reduction in interest rates during 2025 helped improve confidence across parts of the residential development sector, supporting housing market activity and encouraging some developers to progress projects that had previously been delayed or deferred.

The Company's performance also reflects the benefit of operating within the wider Sirius Engineering Group, where civil engineering services can be delivered alongside remediation, earthworks, geotechnical and environmental expertise. This integrated delivery model remains an important differentiator and supports the Company's ability to provide clients with practical, coordinated and commercially efficient solutions.

Whilst residential land development remains the Company's principal market, the Company continued to secure opportunities across adjacent sectors including commercial, industrial and infrastructure-related projects. This has provided additional diversification whilst remaining complementary to the Company's core civil engineering activities.

Market Outlook

The Company's principal market remains linked to residential land development and wider construction activity. Notwithstanding wider economic challenges, underlying demand for new housing across the UK continues to exceed supply. The UK Government's stated objective to deliver 1.5 million new homes over the current Parliament provides favourable medium and long-term market fundamentals for infrastructure, roads, sewers, drainage and enabling works services.

Civil engineering works are often required once land has been remediated, engineered and prepared for development. As a result, the Company is well positioned to benefit from the wider Group's ability to support clients through the full development process, from site investigation and remediation through to primary infrastructure delivery.

Since the year end, geopolitical developments have increased uncertainty within both the UK and global economy. Ongoing international tensions have contributed to volatility in energy markets, higher fuel prices and inflationary pressures across parts of the construction supply chain. In addition, uncertainty regarding economic growth, interest rates and consumer confidence has led to more cautious investment and development decisions within certain sectors.

As a result, the directors anticipate that trading conditions during the first half of 2026 may be more challenging than those experienced during the strong performance achieved in 2025. However, the Company enters the new financial year with an experienced workforce, established client relationships and the continued support of Sirius Engineering Group Limited.

Despite these short-term headwinds, the directors remain confident in the Company's long-term outlook. The continued need for new housing, infrastructure and development-ready land supports demand for high-quality civil engineering services. The Company is well positioned to benefit from these opportunities through its technical capability, operational experience and ability to deliver coordinated infrastructure solutions alongside other Sirius Group companies.

Strategic Report

for the Year Ended 31 December 2025

PRINCIPAL RISKS AND UNCERTAINTIES

The principal risks and uncertainties facing the Company and how they may affect its performance, position or future prospects are set out below:

Health, safety and environmental

The Company is subject to health, safety and environmental risks inherent in civil engineering and infrastructure works. These risks are particularly relevant given the nature of work undertaken on live construction sites, including roads, sewers, drainage, excavations, retaining structures and associated site infrastructure. The Board and business unit leads promote a strong health and safety culture supported by procedures that are continually assessed to ensure best practice. Ongoing health and safety training is provided to employees, with specialist support provided internally and through external consultants where required.

Financial risk management

The Company seeks to minimise financial risk through the preparation of budgets and forecasts, regular monitoring of actual performance against those forecasts and maintaining appropriate financial resources to meet the requirements of the business. The Company's principal financial instruments comprise bank balances, trade and subcontract creditors and trade debtors arising from its operations.

Credit risk

Amounts receivable relate largely to applications on contracts across the Company's customer base. The Company has policies concerning credit offered to customers and regularly monitors amounts outstanding by both ageing and credit limit.

Liquidity risk

The Company manages working capital and cash availability through negotiation with clients and suppliers and regular cash flow forecasting to ensure that sufficient funds are available to meet amounts due. The Company also has the support of Sirius Engineering Group Limited, which is expected to continue for at least the next 12 months.

Recruitment and retention of skilled employees

The civil engineering and construction sectors continue to experience challenges in recruiting and retaining skilled employees. The Company mitigates this risk through investment in training and development, access to Group-wide apprenticeship and progression initiatives, competitive employee benefits and the provision of a safe and positive working environment. The Company employed an average of 43 employees during the year, compared with 35 in 2024, reflecting increased activity levels and the continued development of its workforce.

Fuel and supply chain inflation

The Company is exposed to fluctuations in fuel prices and wider supply chain cost inflation, including plant, materials, haulage, subcontractor and direct site costs. These pressures may impact project margins. This risk is mitigated through proactive procurement, strategic supplier relationships, disciplined contract pricing, regular review of project profitability and continued focus on operational efficiency.

Market conditions and client investment

The Company's principal market remains linked to residential land development and wider construction activity. A reduction in developer confidence, planning delays or funding constraints may affect the timing of project commencements. The Company mitigates this risk through strong client relationships, a healthy operational pipeline, the wider Group's integrated offering and continued diversification into adjacent commercial, industrial and infrastructure-related sectors.

STATEMENT OF DIRECTORS' RESPONSIBILITIES

The directors are responsible for preparing the Strategic Report, the Report of the Directors 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 United Kingdom Generally Accepted Accounting Practice (United Kingdom Accounting Standards and applicable law). 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 judgements and accounting estimates that are reasonable and prudent;

- | 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 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.

STATEMENT AS TO DISCLOSURE OF INFORMATION TO AUDITORS

So far as the directors are aware, there is no relevant audit information (as defined by Section 418 of the Companies Act 2006) of which the company's auditors are unaware, and each director has taken all the steps that he or she ought to have taken as a director in order to make himself or herself aware of any relevant audit information and to establish that the company's auditors are aware of that information.

AUDITORS

The auditors, Anderson Barrowcliff Limited, will be proposed for re-appointment at the forthcoming Annual General Meeting.

ON BEHALF OF THE BOARD:

S Robinson - Director

Report of the Independent Auditors to the Members of

Sirius Civil Engineering Limited

Opinion

We have audited the financial statements of Sirius Civil Engineering Limited (the 'company') for the year ended 31 December 2025 which comprise the Statement of Comprehensive Income, Balance Sheet, Statement of Changes in Equity and Notes to the Financial Statements, 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 102 'The Financial Reporting Standard applicable in the UK and Republic of Ireland' (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 UK, including the FRC'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 directors are responsible for the other information. The other information comprises the information in the Strategic Report and the Report of the Directors, but does not include the financial statements and our Report of the Auditors thereon.

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.

In connection with our audit of the financial statements, 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 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.

Opinions 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 Report of the Directors for the financial year for which the financial statements are prepared is consistent with the financial statements; and

- | the Strategic Report and the Report of the Directors 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 Report of the Directors.

We have nothing to report in respect of the following matters where 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.

Report of the Independent Auditors to the Members of

Sirius Civil Engineering Limited

Responsibilities of directors

As explained more fully in the Statement of Directors' Responsibilities set out on page five, 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 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.

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 a Report of the Auditors 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.

Based on our understanding of the industry, we have considered applicable laws and regulations which may be fundamental to the company's ability to operate or to avoid a material penalty, and we considered the extent to which non-compliance might have a material effect on the financial statements. We considered management's incentives and opportunities for fraudulent manipulation of the financial statements (including the risk of override of controls), and determined that the principal risks were related to the posting of inappropriate manual journal entries to manipulate financial performance, management bias in significant accounting estimates and any significant one-off or unusual transactions.

We discussed among the audit engagement team the opportunities and incentives that may exist within the organisation for fraud and how and where fraud might occur in the financial statements.

Auditors' responsibilities for the audit of the financial statements (continued)

Audit procedures performed by the engagement team included:

- |  | Enquiry of management, those charged with governance and the entity's solicitors around actual and potential litigation and claims. |

- |  | Enquiry of entity staff to identify any instances of non-compliance with laws and regulations. |

- |  | Reviewing financial statement disclosures and testing to supporting documentation to assess compliance with applicable laws and regulations. |

- |  | Auditing the risk of management override of controls, including through testing journal entries and other adjustments for appropriateness, and evaluating the business rationale of significant transactions outside the normal course of business. |

- |  | Challenging estimates and judgements made by management in their significant accounting estimates. |

- |  | Revenue recognition; agreeing a sample of revenue transactions to gain assurance over the occurrence and accuracy of revenue and also to ensure revenue has been recognised in the correct period. |

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. The 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 Report of the Auditors.

Report of the Independent Auditors to the Members of

Sirius Civil Engineering Limited

Our audit work has been undertaken so that we might state to the company's members those matters we are required to state to them in a Report of the Auditors and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the company and the company's members as a body, for our audit work, for this report, or for the opinions we have formed.

Notes to the Financial Statements

for the Year Ended 31 December 2025

1. | STATUTORY INFORMATION

| Sirius Civil Engineering Limited is a private company, limited by shares, registered in England and Wales. The company's registered number and registered office address can be found on the Company Information page.

| The financial statements are presented in sterling which is the functional currency of the company and rounded to the nearest £.

2. | ACCOUNTING POLICIES

| Basis of preparing the financial statements

| These financial statements have been prepared in accordance with Financial Reporting Standard 102 "The Financial Reporting Standard applicable in the UK and Republic of Ireland" and the Companies Act 2006. The financial statements have been prepared under the historical cost convention.

| Financial Reporting Standard 102 - reduced disclosure exemptions

| The company has taken advantage of the following disclosure exemptions in preparing these financial statements, as permitted by FRS 102 "The Financial Reporting Standard applicable in the UK and Republic of Ireland":

| • | the requirements of Section 7 Statement of Cash Flows;

| • | the requirement of paragraph 3.17(d).

| Critical accounting judgements and key sources of estimation uncertainty

| In the application of the companies accounting policies, which are described below, the directors are required to make judgements, estimates and assumptions about the carrying amounts of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

| The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods.

| The judgement (apart from those involving estimations) that management has made in the process of applying the entity's accounting policies and that has the most significant effect on the amounts recognised in the financial statements is the stage of completion of contracts and revenue recognition.

| The company undertakes a number of long term construction contracts. Accounting for these contracts requires a number of assumptions and estimates to be made in relation to the stage of completion and expected outcome of the contract. Each contract has an expected value and is costed appropriately to give an expected margin. Any future changes to estimates of contract revenue or contract costs resulting in a change to the estimated loss or profit of the contract is regularly reviewed by management to ensure accurate reporting of revenue recognition.

| Turnover

| Turnover is stated net of VAT and is recognised when the significant risks and rewards are considered to have been transferred to the buyer. Turnover for the supply of services represents the value of services provided under contracts to the extent that there is a right to consideration and is recorded at the fair value of the consideration received or receivable. Where a contract has only been partially completed at the balance sheet date turnover represents the fair value of the service provided to date based on the stage of completion of the contract activity at the balance sheet date.

| Construction contracts

| Where the outcome of a construction contract can be estimated reliably, revenue and costs are recognised by reference to the stage of completion of the contract activity at the balance sheet date. Stage of completion is measured by reference to the right to consideration in respect of performance of contractual obligations.

| Where the outcome of a construction contract cannot be estimated reliably, contract revenue is recognised to the extent of contract costs incurred where it is probable that they will be recoverable. Contract costs are recognised as expenses in the period in which they are incurred.

| When it is probable that total contract costs will exceed total contract revenue, the expected loss is recognised as an expense immediately.

2. | ACCOUNTING POLICIES - continued

| Tangible fixed assets

| Depreciation is provided at the following annual rates in order to write off the cost less estimated residual value of each asset over its estimated useful life.

| Plant and machinery | - | 33% on cost

| Computer equipment | - | 33% on cost

| Tangible fixed assets are stated at cost (or deemed cost) less accumulated depreciation and accumulated

| impairment losses. Cost includes costs directly attributable to making the asset capable of operating as intended.

| Impairment

| Assets not measured at fair value are reviewed for any indication that the asset may be impaired at each balance sheet date. If such indication exists, the recoverable amount of the asset, or the asset's cash generating unit, is estimated and compared to the carrying amount. Where the carrying amount exceeds its recoverable amount, an impairment loss is recognised in profit or loss unless the asset is carried at a revalued amount where the impairment loss is a revaluation decrease.

| Stocks

| Stocks are stated at the lower of cost and estimated selling price less costs to complete and sell. Cost includes all costs of purchase, costs of conversion and other costs incurred in bringing stock to its present location and condition. Provision is made for damaged, obsolete and slow-moving stock where appropriate.

| Tax

| Current tax represents the amount of tax payable or receivable in respect of the taxable profit (or loss) for the current or past reporting periods. It is measured at the amount expected to be paid or recovered using the tax rates and laws that have been enacted or substantively enacted by the balance sheet date.

| Deferred tax represents the future tax consequences of transactions and events recognised in the financial statements of current and previous periods. It is recognised in respect of all timing differences, with certain exceptions. Timing differences are differences between taxable profits and total comprehensive income as stated in the financial statements that arise from the inclusion of income and expense in tax assessments in periods different from those in which they are recognised in the financial statements. Unrelieved tax losses and other deferred tax assets are recognised only to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits.

| Deferred tax is measured using the tax rates and laws that have been enacted or substantively enacted by the balance sheet date that are expected to apply to the reversal of timing differences.

| Research and development

| Expenditure on research and development is written off in the year in which it is incurred.

| Pension costs and other post-retirement benefits

| The company operates a defined contribution pension scheme. Contributions payable to the company's pension scheme are charged to profit or loss in the period to which they relate.

| Amounts recoverable on contracts

| Amounts recoverable on contracts are stated at cost plus attributable profit to the extent that such profit is reasonably certain and after making provision for any foreseeable losses in completing contracts, less payments on account received.

| Debtors & creditors receivable/payable

| Debtors and creditors with no stated interest rate and receivable or payable are recorded at transaction price. Any losses arising from impairment are recognised in the income statement in other administrative expenses.
