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

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

Cytosorbents Medical UK Limited is a private company limited by shares incorporated in England and Wales. The registered office is The Courtyard, 69 High Street, Ascot SL5 7HP.

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 financial statements have been prepared on a going concern basis, notwithstanding that the company is dependent on income from CytoSorbents Europe GmbH. The ultimate parent company of the group, CytoSorbents Corporation, has raised a going concern risk in its quarterly report pursuant to section 13 or 15(d) of the Securities Exchange Act 1934 for the period ended 30 June 2025. This is related to the Group requiring further capital in order to continue trading for a period of 12 months from 30 June 2025. true

The directors have concluded that the circumstances of the mentioned above represent a material uncertainty which may cast significant doubt over the company's ability to continue as a going concern. Nevertheless, after considering the uncertainties described above, the directors have a reasonable expectation that the company will have adequate resources available, following successful fund raising, to continue to meet their obligations as they fall due and continue in operational existence for a period of at least 12 months from the date of signing these financial statements. For these reasons the directors continue to adopt the going concern basis of accounting in preparing these annual financial statements.

Turnover is recognised to the extent that it is probable that the economic benefits will flow to the company

and the revenue can be reliably measured. Revenue is measured as the fair value of the consideration

received or receivable, excluding discounts, rebates, value added tax and other sales taxes. The following

criteria must also be met before revenue is recognised:

Sale of goods

Revenue from the sale of goods is recognised when all of the following conditions are satisfied:

• The company has transferred the significant risks and rewards of ownership to the buyer;

• The company retains neither continuing managerial involvement to the degree usually associated with ownership nor effective control over the goods sold;

• The amount of revenue can be measured reliably;

• It is probable that the company will receive the consideration due under the transaction; and

• The costs incurred or to be incurred in respect of the transaction can be measured reliably.

Rendering of services

Revenue from a contract to provide services is recognised in the period in which the services are provided in

accordance with the stage of completion of the contract when all of the following conditions are satisfied:

• The amount of revenue can be measured reliably;

• It is probable that the company will receive the consideration due under the contract;

• The stage of completion of the contract at the end of the reporting period can be measured reliably; and

• The costs incurred and the costs to complete the contract can be measured reliably.

Intangible assets are initially recognised at cost. After recognition, under the cost model, intangible assets are

measured at cost less any accumulated amortisation and any accumulated impairment losses.

All intangible assets are considered to have a finite useful life.

Sales data is considered to have a finite useful life and is amortised on a systematic basis over its expected life, which is 5 years.

Stocks are stated at the lower of cost and estimated selling price less costs to complete and sell. Cost comprises direct materials and, where applicable, direct labour costs and those overheads that have been incurred in bringing the stocks to their present location and condition.

Stocks held for distribution at no or nominal consideration are measured at the lower of cost and replacement cost, adjusted where applicable for any loss of service potential.

At each reporting date, an assessment is made for impairment. Any excess of the carrying amount of stocks over its estimated selling price less costs to complete and sell is recognised as an impairment loss in profit or loss. Reversals of impairment losses are also recognised in profit or loss.

Cash and cash equivalents are basic financial assets and include cash in hand, deposits held at call with banks, other short-term liquid investments with original maturities of three months or less, and bank overdrafts. Bank overdrafts are shown within borrowings in current liabilities.

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.

The costs of short-term employee benefits are recognised as a liability and an expense, unless those costs are required to be recognised as part of the cost of stock or fixed assets.

The cost of any unused holiday entitlement is recognised in the period in which the employee’s services are received.

Termination benefits are recognised immediately as an expense when the company is demonstrably committed to terminate the employment of an employee or to provide termination benefits.

Payments to defined contribution retirement benefit schemes are charged as an expense as they fall due.

Where share options are awarded to employees, the fair value of the options at the date of grant is charged to profit or loss over the vesting period. Non-market vesting conditions are taken into account by adjusting the number of equity instruments expected to vest at each reporting date so that, ultimately, the cumulative amount recognised over the vesting period is based on the number of options that eventually vest. Market vesting conditions are factored into the fair value of the options granted. The cumulative expense is not adjusted for failure to achieve a market vesting condition.

The fair value of the award also takes into account non-vesting conditions. These are either factors beyond the control of either party (such as a target based on an index) or factors which are within the control of one or other of the parties (such as the company keeping the scheme open or the employee maintaining any contributions required by the scheme).

Where the terms and conditions of options are modified before they vest, the increase in the fair value of the options, measured immediately before and after the modification, is also charged to profit or loss over the remaining vesting period.

Where equity instruments are granted to persons other than employees, profit or loss is charged with fair value of goods and services received.

The average monthly number of persons (including directors) employed by the company during the year was:

Basis for qualified opinion

We were not appointed as auditor of the company until after 31 December 2023 and thus did not observe the counting of physical inventories at the end of that year. We were unable to satisfy ourselves by alternative means concerning the inventory quantities of £51,570 held on 31 December 2023 by using other audit procedures. Consequently, we were unable to determine whether any adjustment to this amount at 31 December 2023 was necessary or whether there was any consequential effect on the cost of sales for the year ended 31 December 2024.

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 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 qualified opinion.
