HIGH SPEED RAIL FINANCE PLC STRATEGIC REPORT FOR THE YEAR ENDED 31 MARCH 2026 The Directors present their Annual Report on the affairs of High Speed Rail Finance plc (the 'Company') together with the audited financial statements for the year ended 31 March 2026. The Directors in preparing this strategic report have complied with section 414C of the Companies Act 2006.
Principal activities
High Speed Rail Finance plc (the “Company”) is a wholly owned subsidiary of Helix Acquisition Limited, a company incorporated and registered in the United Kingdom. The Company’s main purpose is to administer and manage an element of the debt raising strategy for the Helix Acquisition Limited group (the “Group”) of companies. The Company issued US private placement notes (“USPP notes”) to institutional investors. The Directors do not anticipate any changes to the activities of the Company in the foreseeable future.
Review of the business
The Company made a profit of £3,750 during the year (2025: £5,000). The Company's net assets have increased to £118,750 (2025: £115,000). During the year, the Company recognised a provision of £2.8m in respect of interest on unpaid withholding tax, this will be recharged in full to HS1 Limited and as such there is no impact on the profit for the year for the Company. No dividends have been paid or proposed for the current year (2025: nil). The Directors believe that an understanding of the company’s performance and financial position is more meaningful when assessed on a group-wide basis. Accordingly, reference should be made to the key performance indicators presented in the Annual Report of Helix Acquisition Limited, as referred to in note 18 to these financial statements. Future Developments The Directors consider that reference to the accounts of HS1 Limited provides the most appropriate basis for understanding future developments, as HS1 Limited is the principal trading company of the Group, while High Speed Rail Finance PLC exists to administer the Group’s debt-raising strategy. Key performance indicators The performance of the Company is reflected in the consolidated financial statements of Betjeman Holdings JvCo Limited (the “Group”). The Directors of the Group manage the business on a divisional basis and monitor performance against the Group’s strategy using a range of key performance indicators (“KPIs”). Accordingly, the Company’s Directors consider that a separate analysis of KPIs at Company level is neither necessary nor appropriate for an understanding of the development, performance and position of the Company’s business. A discussion of the Group’s KPIs is included in the Group’s Annual Report and Financial Statements for the year ended 31 March 2026, which do not form part of this report. The Group’s Annual Report is available at the address detailed in note 18 to these financial statements. Page 2
HIGH SPEED RAIL FINANCE PLC STRATEGIC REPORT (CONTINUED) FOR THE YEAR ENDED 31 MARCH 2026
Principal risks and uncertainties
The Company has in place a formal risk management process that enables the organisation to systematically identify, assess, manage and monitor business and financial risks. The principal risks and uncertainties faced are interest rate risk, currency risk, liquidity risk, credit risk and economic risk. The Board of Directors regularly reviews these risks. More information on the management of risks and uncertainties is provided in the financial statements of the intermediary parent company noted above. Interest rate risk Interest rate risk is the risk that fluctuations in interest rates could result in volatility in interest payable and receivable. The Company’s exposure to interest rate risk is low because the interest payments relating to the USPP notes are equally matched by the interest income on the loans to Group undertakings. £58m of the Company's £643.8m of external debt is index-linked, with the remainder being on fixed interest rates. The Company therefore does not choose to hedge the index-linked debt, as it represents a relatively small part of the portfolio. Currency risk The Company is exposed to foreign currency exchange rate risk on the US Dollar (“USD”) element of the USPP notes and the USD element of loans to fellow Group undertakings. Foreign currency exchange rate risk is low as the terms on the USD USPP notes are equally matched by the terms on the USD loans to Group undertakings. Liquidity risk Liquidity risk is the risk that the Company will not be able to meet its financial obligations as they fall due. The Company’s exposure to liquidity risk is low as: • The Company’s financial obligations relating to the USPP notes are equally matched by the receipts on the loans to the Group undertakings; • The Group continues to provide financial support to the Company; and • The Group has adequate resources to meet its financial obligations as they fall due. Credit risk Credit risk is the risk of financial loss to the Company if a counterparty to a financial instrument fails to meet contractual obligations. All loans are to Group undertakings. Management have assessed the qualitative factors under IFRS 9 and have determined that the credit risk is low. Economy Economic risk could include failure to adapt to structural change. The Group monitors potential long-term shifts in the economy that could impact the business, such as travel, commuting, home working and internet shopping. Economic risk could also include passenger flow disruption from new border control requirements. Changes in immigration rules, increased public health measures, or EU border arrangements could negatively impact passenger experience or discourage international travel. Most of the train paths that run on the infrastructure are domestic, which helps to insulate the Group from these risks. Furthermore, juxtaposed border controls, which removes the requirement for passport control at onboarding, is a key competitive advantage over air for international travel. The Group continues to have conversations with customers, suppliers, the regulators, and government to mitigate any risks. Page 3
HIGH SPEED RAIL FINANCE PLC STRATEGIC REPORT (CONTINUED) FOR THE YEAR ENDED 31 MARCH 2026 The Company continues to monitor the ongoing conflict in Iran, noting the longer-term impact this may have on energy prices beyond the end of the current price hedging periods, and will take action accordingly to manage any potential risks arising. Going Concern The Company has prepared these financial statements on a going concern basis, as set out in the Directors' Report.
Approval
This report was approved by the Board and signed on its behalf.

HIGH SPEED RAIL FINANCE PLC DIRECTORS' RESPONSIBILITIES STATEMENT FOR THE YEAR ENDED 31 MARCH 2026 The directors are responsible for preparing the annual 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 judgements 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. The directors are responsible for the maintenance and integrity of the corporate and financial information included on the Company's website. Legislation in the United Kingdom governing the preparation and dissemination of financial statements and other information included in the Directors' Report may differ from legislation in other jurisdictions. ................................................

HIGH SPEED RAIL FINANCE PLC INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF HIGH SPEED RAIL FINANCE PLC Report on the audit of the financial statements 1.Opinion In our opinion the financial statements of High Speed Rail Finance plc (the ‘company’): ∙give a true and fair view of the state of the company’s affairs as at 31 March 2026 and of its profit for the year then ended; ∙have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice, including Financial Reporting Standard 101 “Reduced Disclosure Framework”; and ∙have been prepared in accordance with the requirements of the Companies Act 2006. We have audited the financial statements which comprise: ∙the statement of comprehensive income; ∙the balance sheet; ∙the statement of changes in equity; and ∙the related notes 1 to 20. 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). 2.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 auditor’s 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 Financial Reporting Council’s (the ‘FRC’s’) Ethical Standard as applied to listed entities, 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. 3.Summary of our audit approach
Key audit matters | The key audit matters that we identified in the current year are: ∙Provision for withholding tax (‘WHT’); and ∙Impairment of debtors (valuation of expected credit loss (‘ECL’)). Within this report, the key audit matters are identified as follows: (!) - Newly identified (<>) Similar level of risk
Materiality | The materiality that we used in the current year was £3.2 million. This was based on 0.5% of total assets.
Scoping | Audit work to respond to the risks of material misstatement was performed directly by the audit engagement team.
Significant changes in our approach | A new key audit matter has been identified in the year in relation to withholding tax (“WHT”) for which a £2.8 million provision has been recognised for the first time.
4.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. Our evaluation of the directors’ assessment of the company’s ability to continue to adopt the going concern basis of accounting included: ∙obtaining an understanding of relevant controls around the going concern assessment, including management review controls; ∙assessing the key assumptions made by the directors to capture potential downside risks, including the associated macro-economic assumptions, with a particular focus on the headroom available for debt Page 8
HIGH SPEED RAIL FINANCE PLC INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF HIGH SPEED RAIL FINANCE PLC covenants servicing and the wider Betjeman Holdings Limited group’s (“the group”) cash resources, under severe but plausible stress scenarios; ∙assessing the group’s lending facilities, their availability and compliance with covenants; ∙considering how climate change risks would impact the key assumptions used in the going concern assessment, and ∙evaluating the appropriateness of the financial statement disclosures in respect of going concern. 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. 5.Key audit matters Key audit matters are those matters that, in our professional judgement, were of most significance in our audit of the financial statements of the current period and include the most significant assessed risks of material misstatement (whether or not due to fraud) that we identified. These matters included those which had the greatest effect on: the overall audit strategy; the allocation of resources in the audit; and directing the efforts of the engagement team. These matters were addressed in the context of our audit of the financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters. 5.1 Provision for withholding tax (“WHT”) (!)
Key audit matter description | During the year, management performed a review of the historical debt arrangement records and identified a potential absence of documentation evidencing compliance with UK WHT requirements with respect to payments of interest to overseas lenders. Interest has historically been paid gross of WHT in accordance with applicable double taxation treaties; however, management has identified that the required documentation in order to comply with the relevant HMRC regulations and support this treatment has not been retained. As a result, management has concluded that there is a potential exposure to both WHT and associated interest charges. A provision for £2.8m for the potential interest charge has been recognised and a contingent liability of up to £29.9m for possible payment of WHT and £3.1m additional interest has been disclosed in note. We considered this a key audit matter due to the magnitude of the potential exposure and the level of judgement required in determining the appropriate accounting treatment between a provision and a contingent liability. Further details are included in note 14 and note 20 to the financial statements.
How the scope of our audit responded to the key audit matter | Our procedures in respect of this matter included: ∙Evaluating, working with our taxation specialists, management’s assessment of the potential exposure to withholding tax and associated interest; ∙Assessing the calculation of the exposure, including mechanical accuracy of the calculation and benchmarking to agreed HMRC rates; ∙Inspecting documentation in respect of this matter, including internal correspondence and correspondence with HMRC; and ∙Evaluating the adequacy of disclosures in the financial statements.
Key observations | We are satisfied that the accounting treatment for the provision and contingent liability and related financial statement disclosures are appropriate.
5.2 Impairment of debtors (valuation of expected credit loss (‘ECL’) (<>) Page 9
HIGH SPEED RAIL FINANCE PLC INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF HIGH SPEED RAIL FINANCE PLC
Key audit matter description | Debtors from group undertakings are stated in the balance sheet at £646.7 million, including £544.2 million in debtors falling due in more than one year (note 12) and £102.5million in debtors falling due within one year (note 11) (2025: £729.7 million, including £646.8 million in debtors falling due in more than one year (note 12) and £82.9 million in debtors falling due within one year (note 11)) and these represent 100% (2025: 100%) of the total assets of the company. No ECL provision has been recorded against these assets in either the current or prior year. We consider impairment of debtors a key audit matter due to the material level of intercompany debtors held on the company’s balance sheet and significant judgements used in valuation of ECL. The valuation of an ECL provision depends on a variety of factors including credit default rates and the probability of default, which are the focus of this key audit matter. Further details are included within the accounting policy judgements (note 3) and notes 11 and 12 to the financial statements.
How the scope of our audit responded to the key audit matter | We obtained an understanding of relevant controls related to the valuation of the ECL provision. We challenged management’s valuation of the ECL provision by assessing the key assumptions used in the valuation of the ECL including assessing the credit default rates and the probability of default to external benchmarks. We also evaluated the appropriateness of the financial statement disclosures in respect of ECL.
Key observations | Based on the work performed we concluded that the ECL provision is appropriately stated.
6.Our application of materiality 6.1 Materiality We define materiality as the magnitude of misstatement in the financial statements that makes it probable that the economic decisions of a reasonably knowledgeable person would be changed or influenced. We use materiality both in planning the scope of our audit work and in evaluating the results of our work. Based on our professional judgement, we determined materiality for the financial statements as a whole as follows:
Materiality | £3.2 million
Basis for determining materiality | 0.5% of total assets
Rationale for the benchmark applied | We determined materiality based on total assets as this is the key metric used by management, investors, analysts and lenders, with shareholder value being driven by total asset value.
6.2 Performance materiality We set performance materiality at a level lower than materiality to reduce the probability that, in aggregate, uncorrected and undetected misstatements exceed the materiality for the financial statements as a whole. Performance materiality was set at 70% of materiality for the 2026 audit. In determining performance materiality, we considered the following factors: our risk assessment, including our assessment of the company's overall control environment, and our past experience of the audit, which has indicated a low number of corrected and uncorrected misstatements in prior periods. Our audit procedures were performed to a lower performance materiality of £1.85 million (equivalent to 58% of company materiality) as a result of the company being a component of the Helix Acquisitions Limited group audit. Page 10
HIGH SPEED RAIL FINANCE PLC INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF HIGH SPEED RAIL FINANCE PLC 6.3 Error reporting threshold We agreed with the Audit and Finance Committee (“the Committee”) that we would report to the Committee all audit differences in excess of £160,500, as well as differences below that threshold that, in our view, warranted reporting on qualitative grounds. We also report to the Committee on disclosure matters that we identify when assessing the overall presentation of the financial statements. 7.An overview of the scope of our audit 7.1 Scoping Our audit was scoped by obtaining an understanding of the entity and its environment, including internal control, and assessing the risks of material misstatement. Audit work to respond to the risks of material misstatement was performed directly by the audit engagement team. 7.2 Our consideration of the control environment We have obtained an understanding of the relevant controls such as those relating to the financial reporting cycle and those in relation to our key audit matter. We did not rely on controls for the company audit as the control environment is predominantly manual in nature. 7.3 Our consideration of climate-related risks In planning our audit, we made enquiries of management to understand the extent of the potential impact of climate change risk on the company’s financial statements. We considered how climate change risks would impact the assumptions made in the going concern assessment. The directors have assessed that there is currently no material impact arising from climate change on the judgements and estimates. This is disclosed in note 2.2 to the financial statements. 8.Other information The other information comprises the information included in the annual report, other than the financial statements and our auditor’s 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. 9.Responsibilities of directors As explained more fully in the directors’ responsibilities statement, 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. 10.Auditor’s 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 auditor’s 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. Page 11
HIGH SPEED RAIL FINANCE PLC INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF HIGH SPEED RAIL FINANCE PLC A further description of our responsibilities for the audit of the financial statements is located on the FRC’s website at: . This description forms part of our auditor’s report. 11.Extent to which the audit was considered capable of detecting irregularities, including fraud 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. 11.1 Identifying and assessing potential risks related to irregularities In identifying and assessing risks of material misstatement in respect of irregularities, including fraud and non-compliance with laws and regulations, we considered the following: ∙the nature of the industry and sector, control environment and business performance including the design of the company’s remuneration policies, key drivers for directors’ remuneration, bonus levels and performance targets; ∙results of our enquiries of management, the directors and the Audit and Finance Committee about their own identification and assessment of the risks of irregularities, including those that are specific to the company’s sector; ∙any matters we identified having obtained and reviewed the company’s documentation of their policies and procedures relating to: ∙identifying, evaluating and complying with laws and regulations and whether they were aware of any instances of non-compliance; ∙detecting and responding to the risks of fraud and whether they have knowledge of any actual, suspected or alleged fraud; ∙the internal controls established to mitigate risks of fraud or non-compliance with laws and regulations; the matters discussed among the audit engagement team including tax specialists regarding how and where fraud might occur in the financial statements and any potential indicators of fraud. As a result of these procedures, we considered the opportunities and incentives that may exist within the organisation for fraud. In common with all audits under ISAs (UK), we are also required to perform specific procedures to respond to the risk of management override. We also obtained an understanding of the legal and regulatory framework that the company operates in, focusing on provisions of those laws and regulations that had a direct effect on the determination of material amounts and disclosures in the financial statements. The key laws and regulations we considered in this context included the UK Companies Act and tax legislation. In addition, we considered provisions of other laws and regulations that do not have a direct effect on the financial statements but compliance with which may be fundamental to the company’s ability to operate or to avoid a material penalty. 11.2 Audit response to risks identified As a result of performing the above, we identified “Provision for withholding tax” as a key audit matter related to the potential risk of non-compliance with laws and regulations. The key audit matters section of our report explains the matter in more detail and also describes the specific procedures we performed in response to that key audit matter. We did not identify any key audit matters related to the potential risk of fraud. Our procedures to respond to risks identified included the following: ∙reviewing the financial statement disclosures and testing to supporting documentation to assess compliance with provisions of relevant laws and regulations described as having a direct effect on the financial statements; ∙enquiring of management, the Audit and Finance Committee and in-house legal counsel concerning actual and potential litigation and claims; ∙performing analytical procedures to identify any unusual or unexpected relationships that may indicate risks of material misstatement due to fraud; ∙reading minutes of meetings of those charged with governance, reviewing internal audit reports and reviewing correspondence with HMRC; and Page 12
HIGH SPEED RAIL FINANCE PLC INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF HIGH SPEED RAIL FINANCE PLC ∙in addressing the risk of fraud through management override of controls, testing the appropriateness of journal entries and other adjustments; assessing whether the judgements made in making accounting estimates are indicative of a potential bias; and evaluating the business rationale of any significant transactions that are unusual or outside the normal course of business.

HIGH SPEED RAIL FINANCE PLC NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 31 MARCH 2026
1. | General information
High Speed Rail Finance plc (the “Company”) is a public company limited by shares, incorporated under Companies Act 2006, and domiciled in the United Kingdom and registered in England and Wales. The financial statements were prepared in accordance with Financial Reporting Standard 101 Reduced Disclosure Framework (FRS 101) and in accordance with applicable accounting standards. The Company’s financial statements are presented in Pound Sterling, which is the currency of the principal economic environment in which the Company operates. All values are rounded to the nearest million pounds except when otherwise indicated. The nature of the Company's operations and its principal activities are set out in the strategic report on page 2. The material accounting policies adopted by the Company are set out below. Unless otherwise stated, these have been applied consistently to all periods presented on these financial statements. 2.Accounting policies
| 2.1 | Basis of preparation

and ultimately, the Betjeman Holdings JvCo Limited group. The main trading company of the Betjeman Holdings JvCo Limited group is HS1 Limited, a company that holds the concession to operate, maintain and renew the high speed rail line connecting London’s St Pancras International Station to Europe via the Channel Tunnel. At 31 March 2026, the Company was in a net current assets position, however it is dependent on the performance of HS1 Limited to repay its liabilities as they fall due. The Group has prepared a range of forecast scenarios to reflect the impact of the economic uncertainty. The Directors have reviewed business forecasts against the cashflow, and covenant requirements of the Group and concluded the Group is able to meet its obligations as they fall due. Under all the cases the Company can meet its covenants, has sufficient liquidity, and is able to pay its scheduled borrowing repayments as they fall due. The Directors have also reviewed the plans to protect the Group’s liquidity, including working capital and cost reduction options. These forecasts also benefit from the security of revenue reflecting the UK Government underpinning arrangements. The Group also performed analysis of downside scenarios, with limited growth in train paths, noting that in these scenarios the Group would be able to meet covenant requirements and have sufficient liquidity to operate. The financial statements have accordingly been prepared on a going concern basis. The Company also considers climate change in its going concern analysis. The Company does not consider this to be material to the Company, including during the going concern assessment period, i.e. 12 months following the signing of the financial statements. Having due regard to the performance of HS1 Limited, the availability of working capital and the facilities under the loan agreement with the parent undertaking, the Directors believe that the Company has sufficient resources to meet its liabilities. The financial statements have accordingly been prepared on a going concern basis.
| 2.3 | Financial instruments
A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity. a. Financial assets and financial liabilities Initial recognition and measurement The Company recognises financial assets and financial liabilities when it becomes a party to the contractual provisions of the instrument. Regular way purchases and sales of financial assets are recognised on the trade-date, which is the date on which the Company has committed to purchase or sell the instrument in question. Classification and measurement of financial assets and financial liabilities On initial recognition financial assets are classified and measured at amortised cost, fair value through other comprehensive income (“FVOCI”) or fair value through profit or loss (“FVTPL”). The classification depends on both the business model for managing the financial assets and their contractual cash flow characteristics. The Company has applied the practical expedient, the Company initially measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss, transaction costs. Page 18
HIGH SPEED RAIL FINANCE PLC NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 31 MARCH 2026 2.Accounting policies (continued) In order for a financial asset to be classified and measured at amortised cost or fair value through OCI, it needs to give rise to cash flows that are ‘solely payments of principal and interest (“SPPI”)’ on the principal amount outstanding. This assessment is referred to as the SPPI test and is performed at an instrument level. The Company’s business model for managing financial assets refers to how it manages its financial assets to generate cash flows. The business model determines whether cash flows will result from collecting contractual cash flows, selling the financial assets, or both. On initial recognition, financial liabilities are classified as measured at either amortised cost or FVTPL. The Company’s financial liabilities include loans and borrowing. Subsequent measurement - Financial assets at amortised cost The Company measures financial assets at amortised cost if both of the following conditions are met: • The financial asset is held within a business model with the objective to hold financial assets in order to collect contractual cash flows and, • The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding. Financial assets at amortised cost are subsequently measured using the effective interest rate (EIR) method and are subject to impairment. Gains and losses are recognised in profit or loss when the asset is derecognised, modified or impaired. Derecognition A financial asset is primarily derecognised when: • The rights to receive cash flows from the asset have expired or • The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a ‘passthrough’ arrangement; and either (a) the Company has transferred substantially all the risks and rewards of the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset, but has transferred control of the asset. Impairment of financial assets The Company recognises an allowance for expected credit losses (ECLs) for all debt instruments not held at fair value through profit or loss. ECLs are recognised in two stages. For credit exposures for which there has not been a significant increase in credit risk since initial recognition, ECLs are provided for credit losses based on probability of default within the next 12-months (a 12-month ECL). For those credit exposures for which there has been a significant increase in credit risk since initial recognition, a loss allowance is required for credit losses expected over the remaining life of the exposure, irrespective of the timing of the default (a lifetime ECL). When assessing whether there has been a significant increase in credit risk management have used qualitative elements such as changes to the economy, late payment of interest, whether interest has been waived and whether there has been evidence from internal reporting to indicate economic performance would be worse than expected. Page 19
HIGH SPEED RAIL FINANCE PLC NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 31 MARCH 2026 2.Accounting policies (continued) No adjustment was required to the Company’s financial statements for ECL in the year. Subsequent measurement - financial liabilities Financial liabilities at fair value through profit or loss include financial liabilities held for trading. Gains or losses on liabilities held for trading are recognised in the statement of profit or loss. This category is the most relevant to the Company. After initial recognition, interest-bearing loans and borrowings are subsequently measured at amortised cost using the EIR method. Gains and losses are recognised in profit or loss when the liabilities are derecognised as well as through the EIR amortisation process. Derecognition A financial liability is derecognised when the obligation under the liability is discharged or cancelled or expires.
| 2.4 | Trade debtors and creditors
Trade debtors and creditors, which generally have 30-90 day payment terms are recognised and carried at the lower of their original invoiced value and recoverable amount. Provision for impairment of receivables is made through profit or loss when there is objective evidence that the Company will not be able to recover balances in full. Balances are written off when the probability of recovery is assessed as being remote.
| 2.5 | Cash at bank and in hand
Cash and short term deposits in the balance sheet comprise cash at banks and in hand and short term deposits with an original maturity of three months or less.
| 2.6 | Interest receivable and interest payable
Other interest receivable comprises interest receivable from loans to fellow Group undertakings. Interest receivable and payable is recognised in the profit and loss account as it accrues using the effective interest rate method. Finance charges, including premiums payable on settlement or redemptions and direct issue costs are accounted for on an accruals basis and taken to the profit and loss account using the effective interest rate method and are added to the carrying value of the instrument to the extent that they are not settled in the period in which they arise. Page 20
HIGH SPEED RAIL FINANCE PLC NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 31 MARCH 2026 2.Accounting policies (continued)
| 2.7 | Taxation
Tax on the profit or loss for the year comprises only current tax. Tax is recognised in the profit and loss account except to the extent that it relates to items recognised directly in equity or other comprehensive income, in which case it is recognised directly in equity or other comprehensive income. Current tax is the expected tax payable or receivable on the taxable income or loss for the year, using tax rates enacted or substantively enacted at the balance sheet date, and any adjustment to tax payable in respect of previous years.
3. | Judgements 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. Provision for expected credit losses of intercompany receivables The Company recognises an allowance for ECLs for all debt instruments not held at fair value through profit or loss. As explained in note 2.3, ECL are measured as an allowance equal to 12-month ECL for stage 1 assets, or lifetime ECL for stage 2 or stage 3 assets. An asset moves to stage 2 when its credit risk has increased significantly since initial recognition. IFRS 9 does not define what constitutes a significant increase in credit risk. In assessing whether the credit risk of an asset has significantly increased the Company takes into account qualitative and quantitative reasonable and supportable forward-looking information. In calculating an ECL on intercompany balances management have determined whether the default risk on the loan has increased and consequently if there has been a significant increase in credit risk. This evaluation of the default rate is open to significant judgements, estimates and assumptions. Management have also assessed the qualitative factors under IFRS 9. The Company did not recognise any ECLs at the year end as the estimated ECL is not material, with a value of £0.2m (2025: £0.3m). A 0.2% increase in the default would result in an ECL of £1.0m. Critical judgements in applying the Company’s accounting policies The Directors do not consider there to be any critical judgments involved in the application of the accounting policies for the preparation of the financial statements.

The other income of £2.8m relates to unpaid witholding tax interest. The Company has recognised a £2.8m provision in the year (note 14) related to unpaid withholding tax interest. This amount has been recharged in full to HS1 Limited, and is included within other income. Additionally, the Company received other income of £3,200 (2025: £4,450) related to admin expenses incurred by the Company during the year which are recharged in full to HS1 Limited.

HIGH SPEED RAIL FINANCE PLC NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 31 MARCH 2026
20. | Contingent liability
During the year ended 31 March 2026, a review of Company’s historical debt arrangement records identified a potential absence of documentation evidencing compliance with UK withholding tax (‘WHT’) requirements on payments of interest to overseas lenders. Following the advice received from our legal and tax advisers it was concluded that it is probable late paid interest will be due to HMRC of £2.8m, which has been recognised as a provision (note 14) and that it is possible that WHT may be payable to HMRC. The potential maximum WHT payment is £29.9m. Accordingly, the Company recognises a contingent liability for this amount. It is possible that a proportion of this liability may be recoverable through the repayment claim mechanism. The Company also notes that it is possible additional interest of £3.1m accrued on the WHT may become payable, for the period between 2017 and 2022. The Company is working with HMRC to rectify this matter. The Company notes that any required payments would be recharged in full to HS1 Limited.
