NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEAR ENDED 31ST DECEMBER 2024

1. | STATUTORY INFORMATION

| Eleusis Therapeutics Ltd 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.

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" including the provisions of Section 1A "Small Entities" and the Companies Act 2006. The financial statements have been prepared under the historical cost convention.

| Going concern

| At the time of approving the financial statements, the directors have a reasonable expectation that the company has adequate resources to continue in operational existence for the foreseeable future. The company has obtained confirmations and assurances from its group undertakings that they will continue to support the company for at least twelve months from the signing of these financial statements and meet all third party liabilities as they become due. Thus the directors continue to adopt the going concern basis of accounting in preparing the financial statements.

| Financial instruments

| The company has elected to apply the provisions of Section 11 ‘Basic Financial Instruments’ of FRS 102 to all of its financial instruments.

| Financial instruments are recognised when the company becomes party to the contractual provisions of the instrument.

| Financial assets and liabilities are offset, with the net amounts presented in the financial statements, when there is a legally enforceable right to set off the recognised amounts and there is an intention to settle on a net basis or to realise the asset and settle the liability simultaneously.

| Taxation

| Taxation for the year comprises current and deferred tax. Tax is recognised in the Profit and Loss Account, except to the extent that it relates to items recognised in other comprehensive income or directly in equity.

| Current or deferred taxation assets and liabilities are not discounted.

| Current tax is recognised at the amount of tax payable using the tax rates and laws that have been enacted or substantively enacted by the balance sheet date.

| Deferred tax

| Deferred tax is recognised in respect of all timing differences that have originated but not reversed at the balance sheet date.

| Timing differences arise from the inclusion of income and expenses in tax assessments in periods different from those in which they are recognised in financial statements. Deferred tax is measured using tax rates and laws that have been enacted or substantively enacted by the year end and that are expected to apply to the reversal of the timing difference.

| 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.

FOR THE YEAR ENDED 31ST DECEMBER 2024

2. | ACCOUNTING POLICIES - continued

| Research and development

| Research expenditure is written off against profits in the year in which it is incurred. Identifiable development expenditure is capitalised to the extent that the technical, commercial and financial feasibility can be demonstrated.

| Foreign currencies

| Assets and liabilities in foreign currencies are translated into sterling at the rates of exchange ruling at the balance sheet date. Transactions in foreign currencies are translated into sterling at the rate of exchange ruling at the date of transaction. Exchange differences are taken into account in arriving at the operating result.

| 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.

| Research and development tax credits

| The company may be entitled to claim special tax allowances in relation to qualifying research and development expenditure (e.g. R&D tax credits). The company accounts for such allowances as tax credits, which means that they are recognised when it is probable that benefit will flow to the company and that benefit can be reliably measured. As there is no guarantee that a claim will be approved, the credit will be recognised on the cash receipt basis, and any prior tax allowances are amended accordingly.

| As a company that carries out extensive research and development activities, the company benefits from the UK research and development tax credit regime under the scheme for small or medium-sized enterprises. Under the SME regime, the company is able to surrender some of its trading losses that arise from qualifying research and development activities for a cash rebate applicable to such qualifying gross research and development expenditure. A large portion of costs relating to research and development, clinical trials and manufacturing activities are eligible for inclusion within these tax credit cash rebate claims.

| The UK research and development tax credit is fully refundable to the company and is not dependent on current or future taxable income. The company has recorded the entire benefit from the UK research and development tax credit as a benefit which is included in the company taxes line and accordingly, reflected as part of the company tax provision.
