NOTES TO THE FINANCIAL STATEMENTS

FOR THE YEAR ENDED 31 DECEMBER 2025

1. | STATUTORY INFORMATION

| Stem CellX 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 pound.

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.

| Preparation of consolidated financial statements

| The financial statements contain information about Stem CellX Limited as an individual company and do not contain consolidated financial information as the parent of a group. The company is exempt under Section 399(2A) of the Companies Act 2006 from the requirements to prepare consolidated financial statements.

| Significant judgements and estimates

| No judgements have been made in the process of applying the below accounting policies that have had the most significant effect on amounts recognised in the financial statements.

| There are no key assumptions concerning the future and other key sources of estimation uncertainty at the reporting date that have a significant risk of causing material adjustment to the carrying amounts of assets and liabilities within the next financial year.

| Turnover

| Turnover is measured at the fair value of the consideration received or receivable net of VAT.

| Turnover from the sale of goods is recognised when significant risks and rewards of ownership of the goods have transferred to the buyer, the amount of turnover can be measured reliably, it is probable that the economic benefits associated with the transaction will flow to the company and the costs incurred or to be incurred in respect of the transaction can be measured reliably. This is usually on completion of the sale.

| Intangible assets

| Intangible assets are initially measured at cost. After initial recognition, intangible assets are measured at cost less any accumulated amortisation and any accumulated impairment losses.

| Intellectual property is being amortised evenly over its estimated useful life of five years.

2. | ACCOUNTING POLICIES - continued

| Tangible fixed assets

| Tangible fixed assets are stated at cost (or deemed cost) or valuation less accumulated depreciation and accumulated impairment losses. Cost includes costs directly attributable to making the asset capable of operating as intended.

| Depreciation is provided on all tangible fixed assets, at rates calculated to write off the cost, less estimated residual value, of each asset on a systematic basis over its expected useful life as follows:

| Computer equipment |  | 33% straight line |  |

| Plant and Machinery |  | 25% reducing balance |  |

| Investments in subsidiaries

| Investments in subsidiary undertakings are recognised at cost.

| Taxation

| Taxation for the year comprises current and deferred tax. Tax is recognised in the Income Statement, 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.

| Research and development

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

| 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.

| Investments

| Unlisted investments are initially recognised at cost. Provision is made for any permanent diminution in value of unlisted investments.
