These financial statements have been prepared and delivered in accordance with the provisions applicable to companies subject to the small companies regime.

The directors of the company have elected not to include a copy of the profit and loss account within the financial statements.true

STS Medical Ltd is a private company limited by shares incorporated in England and Wales. The registered office is Lanesborough House, The Laurels Business Park, Heol Y Rhosog, Cardiff, United Kingdom, CF3 2EW.

The financial statements cover the period from 30 March 2024 (date of incorporation) to 31 March 2025. This is the first period of account for the company.

As this is the first set of financial statements prepared by the company, no comparative figures are presented. Consequently, the amounts presented in these financial statements are not directly comparable with any previous period.

These financial statements have been prepared in accordance with FRS 102 “The Financial Reporting Standard applicable in the UK and Republic of Ireland” (“FRS 102”) and the requirements of the Companies Act 2006 as applicable to companies subject to the small companies regime. The disclosure requirements of section 1A of FRS 102 have been applied other than where additional disclosure is required to show a true and fair view.

The financial statements are prepared in sterling, which is the functional currency of the company. Monetary amounts in these financial statements are rounded to the nearest £.

The financial statements have been prepared under the historical cost convention. The principal accounting policies adopted are set out below.

The company has taken advantage of the exemption under section 399 of the Companies Act 2006 not to prepare consolidated accounts, on the basis that the group of which this is the parent qualifies as a small group. The financial statements present information about the company as an individual entity and not about its group.

The company is dependant upon the support of its parent companytrue, Surface Technology Services B.V., and expects this support to continue. On this basis, the directors consider it appropriate to prepare the financial statements on the going concern basis. The financial statements do not include any adjustments that would result from a withdrawal of support from its parent company.

Interests in subsidiaries, associates and jointly controlled entities are initially measured at cost and subsequently measured at cost less any accumulated impairment losses. The investments are assessed for impairment at each reporting date and any impairment losses or reversals of impairment losses are recognised immediately in profit or loss.

A subsidiary is an entity controlled by the company. Control is the power to govern the financial and operating policies of the entity so as to obtain benefits from its activities.

Financial instruments are recognised in the company's balance sheet 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.

Basic financial assets, which include debtors and cash and bank balances, are initially measured at transaction price including transaction costs and are subsequently carried at amortised cost using the effective interest method unless the arrangement constitutes a financing transaction, where the transaction is measured at the present value of the future receipts discounted at a market rate of interest. Financial assets classified as receivable within one year are not amortised.

These financial statements have been prepared in accordance with FRS 102 “The Financial Reporting Standard applicable in the UK and Republic of Ireland” (“FRS 102”) and the requirements of the Companies Act 2006 as applicable to companies subject to the small companies regime. The disclosure requirements of section 1A of FRS 102 have been applied other than where additional disclosure is required to show a true and fair view.

Basic financial liabilities, including creditors, bank loans, loans from fellow group companies and preference shares that are classified as debt, are initially recognised at transaction price unless the arrangement constitutes a financing transaction, where the debt instrument is measured at the present value of the future payments discounted at a market rate of interest. Financial liabilities classified as payable within one year are not amortised.

Debt instruments are subsequently carried at amortised cost, using the effective interest rate method.

Trade creditors are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers. Amounts payable are classified as current liabilities if payment is due within one year or less. If not, they are presented as non-current liabilities. Trade creditors are recognised initially at transaction price and subsequently measured at amortised cost using the effective interest method.

Equity instruments issued by the company are recorded at the proceeds received, net of transaction costs. Dividends payable on equity instruments are recognised as liabilities once they are no longer at the discretion of the company.

Where shares are deemed to be debt instruments in line with the commercial substance of the arrangements, amounts are recognised as financial liabilities. Preference shares have therefore been recognised within liabilities.

As the income statement has been omitted from the filing copy of the financial statements, the following information in relation to the audit report on the statutory financial statements is provided in accordance with s444(5B) of the Companies Act 2006.

The auditor's report is unqualified and includes the following:

In our opinion the financial statements:

• give a true and fair view of the state of the company's affairs as at 31 March 2025 and of its loss for the period 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.

As at 31 March 2025, the company had no commitments or guarantees. The company has entered into a share purchase agreement during the year which includes warranties, indemnities and a tax covenant. The directors do not consider it probable that a liability will arise and therefore no provision has been recognised. Any contingent consideration payable under this agreement is not expected to be material.
