The directors present the strategic report for the year ended 31 December 2025.

The principal activity of the group continued to be that of development, production, procurement and supply of a range of silicon and non-silicone based speciality chemicals and intermediates to agreed specifications and to regulated markets including pharmaceuticals, food and cosmetics.

Momentive Performance Materials Holdings UK Limited is a group holding company that owns shares in a subsidiary. At present, the company holds 100% of the shares in Basildon Chemical Co. Limited.

In September 2018, MPM Holdings Inc., a global silicones and advanced materials company, together with SJL Partners LLC, KCC Corporation, and Wonik QnC Corporation (collectively referred to as the Investor Group), entered into a definitive merger agreement under which the Investor Group would acquire Momentive. The transaction was valued at approximately $3.1 billion, inclusive of net debt, pension, and OPEB liabilities.

On 6 January 2021, KCC Corp sold its silicone division—including its entire shareholding in Basildon Chemical Co. Limited—to MPM Holdings Inc.. Subsequently, the company was acquired by Momentive Performance Materials Holdings UK Limited.

During the year, the group’s principal activity remained the development, production, procurement, and supply of a range of silicone and non-silicone-based speciality chemicals and intermediates. These products are manufactured to agreed specifications and supplied to regulated markets, including pharmaceuticals, food, and cosmetics.

The group recorded an increase in sales in 2025 compared to 2024, primarily driven by strong demand from customers in the Middle East and Europe, offset by a decline in North and South America. The growth in demand during 2025 reflected a stable market environment and continued share expansion.

The group continues to manufacture both silicone and non-silicone-based speciality chemicals and has entered into a tolling services agreement with GmbH. Under this arrangement, the group provides manufacturing services to GmbH and receives compensation on a cost-plus fee basis.

In addition, the group continues to recognise revenue from its customers, with charges from GmbH relating to the finished products associated with these sales.

The results for the 12-month period and the financial position of the company and its subsidiary are presented in the accompanying financial statements. These results reflect the operational and market factors outlined above.

The subsidiary is exposed to low levels of price, credit, liquidity, and cash flow risk. These risks are managed through retained profits and access to the financial support of its parent group, should the need arise.

Management’s objectives are to maintain adequate liquidity to meet day-to-day trading requirements, minimise exposure to fluctuations in customer cash flows, and manage future cash flows arising from trading activities.

The subsidiary makes limited use of financial instruments, other than an operational bank account. Consequently, its exposure to price, credit, liquidity, and cash flow risk is not considered material in assessing its assets, liabilities, financial position, or profit and loss.

The group continues to strengthen its product portfolio through the utilisation of internal technical resources, the acquisition of complementary products targeted at key markets, and the significant research and development capabilities within the Momentive group, providing access to innovative and advanced technology.

Momentive Performance Materials Limited has further enhanced Basildon Chemical Co. Limited’s position through expanded geographic coverage and strengthened relationships with key customers. An improvement in global economic conditions anticipated in 2026 is expected to drive increased orders and sales across target markets.

In September 2018, MPM Holdings Inc., a global silicones and advanced materials company, together with SJL Partners LLC, KCC Corporation, and Wonik QnC Corporation (collectively, the Investor Group), entered into a definitive merger agreement under which the Investor Group acquired Momentive in a transaction valued at approximately $3.1 billion, including the assumption of net debt, pension, and OPEB liabilities.

In January 2021, KCC Corp sold its silicone division, including 100% of the shares in Basildon Chemical Co. Limited, to MPM Holdings Inc.. Subsequently, the company was acquired by Momentive Performance Materials Holdings UK Limited. The expected strategic synergies, combined with planned system and business integration and ongoing development of technology platforms, are anticipated to support continued business growth and improved earnings in the years ahead.

The subsidiary company employs a range of performance measures to effectively monitor and manage its operations. These include both financial and non-financial indicators, with the most significant being the key performance indicators (KPIs). The KPIs for the year ended 31 December 2025, together with comparative figures for prior years, are summarised below.

On behalf of the board

The directors present their annual report and financial statements for the year ended 31 December 2025.

The results for the year are set out on page 8.

No ordinary dividends were paid. The directors do not recommend payment of a further dividend.

The directors who held office during the year and up to the date of signature of the financial statements were as follows:

The group manages its cash and borrowing requirements in order to maximise interest income and minimise interest expense, whilst ensuring the group has sufficient liquid resources to meet the operating needs of the business.

The group’s principal foreign currency exposures arise from trading with overseas companies. Group policy permits but does not demand that these exposures may be hedged in order to fix the cost in sterling.

Trade debtors are monitored on an ongoing basis and provision is made for doubtful debts where necessary.

Price risk relates to the Group's ability to purchase commodities at a competitive and profitable rate.

The group develops specialist silicone and natural oil-based chemicals used in small but critical quantities across a wide range of applications. Its experienced R&D team supports both established products and the development and scale-up of new, high-value solutions, helping the company compete in niche markets and serve major global customers. Since its acquisition by Momentive Performance Materials in 2021, R&D activities have accelerated, leveraging the company’s unique expertise within a larger international group.

In accordance with the company's articles, a resolution proposing that Xeinadin Audit Limited be reappointed as auditor of the group will be put at a General Meeting.

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 United Kingdom Generally Accepted Accounting Practice (United Kingdom Accounting Standards and applicable law). 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 group and company, and of the profit or loss of the group 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 group and company will continue in business.

The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the group’s and company’s transactions and disclose with reasonable accuracy at any time the financial position of the group and company and enable them to ensure that the financial statements comply with the Companies Act 2006. They are also responsible for safeguarding the assets of the group and company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

The company has chosen in accordance with Companies Act 2006, s. 414C(11) to set out in the company's strategic report information required by Large and Medium-sized Companies and Groups (Accounts and Reports) Regulations 2008, Sch. 7 to be contained in the directors' report. It has done so in respect of the following matters:true

• Principal activities of the company

• Business review including principal risks and uncertainties

• Strategy for Growth

So far as each person who was a director at the date of approving this report is aware, there is no relevant audit information of which the auditor of the company is unaware. Additionally, the directors individually have taken all the necessary steps that they ought to have taken as directors in order to make themselves aware of all relevant audit information and to establish that the auditor of the company is aware of that information.

This report has been prepared in accordance with the provisions applicable to companies entitled to the medium-sized companies exemption.

We have audited the financial statements of Momentive Performance Materials Holdings UK Limited (the 'parent company') and its subsidiaries (the 'group') for the year ended 31 December 2025 which comprise the group statement of comprehensive income, the group balance sheet, the company balance sheet, the group statement of changes in equity, the company statement of changes in equity, the group statement of cash flows and notes to the financial statements, including significant accounting policies. The financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 102 The Financial Reporting Standard applicable in the UK and Republic of Ireland (United Kingdom Generally Accepted Accounting Practice).

In our opinion the financial statements:

• give a true and fair view of the state of the group's and the parent company's affairs as at 31 December 2025 and of the group's profit for the year 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.

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 group and parent 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 opinion.

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.

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 group's and parent 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.

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.

Opinions on other matters prescribed by the Companies Act 2006

In our opinion, based on the work undertaken in the course of our audit:

• The information given in the strategic report and the directors' report for the financial year for which the financial statements are prepared is consistent with the financial statements; and

• The strategic report and the directors' report have been prepared in accordance with applicable legal requirements.

In the light of the knowledge and understanding of the group and the parent company and their environment obtained in the course of the audit, we have not identified material misstatements in the strategic report or the directors' report.

We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion:

• adequate accounting records have not been kept by the parent company, or returns adequate for our audit have not been received from branches not visited by us; or

• the parent company financial statements are not in agreement with the accounting records and returns; or

• certain disclosures of directors' remuneration specified by law are not made; or

• we have not received all the information and explanations we require for our audit.

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 parent 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 parent company or to cease operations, or have no realistic alternative but to do so.

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.

The extent to which our procedures are capable of detecting irregularities, including fraud, is detailed below.

In identifying and assessing risks of material misstatement in respect of irregularities including fraud and non-compliance with laws and regulations we have considered the following:

• The nature of the industry and sector, control environment and business performance including the company’s performance targets.

• Results of the enquiries of management about their own identification and assessment of the risks of irregularities.

• Any matters we have 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 regarding how and where fraud might occur in the financial statements and any potential indicators of fraud.

As a result of these procedures, we consider the opportunities and incentives that may exist within the organisation for fraud and identified the greatest potential for fraud in the following areas: timing of recognition of income. 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 frameworks 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 UK Companies Act, health and safety and tax legislation.

In addition, we considered the provisions for 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 material penalty.

Audit response to risks identified

Our procedures to respond to risks identified include the following:

• reviewing the financial statement disclosures and testing to supporting documentation to assess compliance with provision of relevant laws and regulations described as having a direct effect on the financial statements;

• enquiring of management 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;

• reviewing correspondence with HMRC; and

• in addressing the risk of fraud through management override of controls, testing the appropriateness of journal entries and other adjustments; assessing whether the judgements 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.

We also communicated relevant identified laws and regulations and potential fraud risks to all engagement team members including internal specialists and, remained alert to any indications of fraud or non-compliance with laws and regulations throughout the audit.

No instances of material non-compliance were identified. However, the likelihood of detecting irregularities, including fraud, is limited by the inherent difficulty in detecting irregularities, the effectiveness of the entity’s controls, and the nature, timing and extent of the audit procedures performed. Irregularities that result from fraud might be inherently more difficult to detect that irregularities that result from error.

As explained above, there is an unavoidable risk that material misstatements may not be detected, even though the audit has been planned and performed in accordance with ISAs (UK).

A further description of our responsibilities is available on the Financial Reporting Council’s website at: https://www.frc.org.uk/auditorsresponsibilities. This description forms part of our auditor's report.

Use of our report

This report is made solely to the parent company’s members, as a body, in accordance with Chapter 3 of Part 16 of the Companies Act 2006. Our audit work has been undertaken so that we might state to the parent company’s members those matters we are required to state to them in an auditor's report and for no other purpose. To the fullest extent permitted by law, we do not accept or assume responsibility to anyone other than the parent company and the parent company’s members as a body, for our audit work, for this report, or for the opinions we have formed.

These financial statements have been prepared in accordance with the provisions relating to medium-sized groups.

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

Momentive Performance Materials Holdings UK Limited (“the company”) is a private limited company domiciled and incorporated in England and Wales. The registered office is 5 Cranfield Road, Lostock Industrial Estate, Bolton, Lancashire, UK, BL6 4QD.

The group consists of Momentive Performance Materials Holdings UK Limited and all of its subsidiaries.

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.

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 is a qualifying entity for the purposes of FRS 102, being a member of a group where the parent of that group prepares publicly available consolidated financial statements, including this company, which are intended to give a true and fair view of the assets, liabilities, financial position and profit or loss of the group. The company has therefore taken advantage of exemptions from the following disclosure requirements for parent company information presented within the consolidated financial statements:

• Section 7 ‘Statement of Cash Flows’: Presentation of a statement of cash flow and related notes and disclosures;

• Section 11 ‘Basic Financial Instruments’ and Section 12 ‘Other Financial Instrument Issues: Interest income/expense and net gains/losses for financial instruments not measured at fair value; basis of determining fair values; details of collateral, loan defaults or breaches, details of hedges, hedging fair value changes recognised in profit or loss and in other comprehensive income;

• Section 26 ‘Share based Payment’: Share-based payment expense charged to profit or loss, reconciliation of opening and closing number and weighted average exercise price of share options, how the fair value of options granted was measured, measurement and carrying amount of liabilities for cash-settled share-based payments, explanation of modifications to arrangements;

• Section 33 ‘Related Party Disclosures’: Compensation for key management personnel.

In the parent company financial statements, the cost of a business combination is the fair value at the acquisition date of the assets given, equity instruments issued and liabilities incurred or assumed, plus costs directly attributable to the business combination. The excess of the cost of a business combination over the fair value of the identifiable assets, liabilities and contingent liabilities acquired is recognised as goodwill. The cost of the combination includes the estimated amount of contingent consideration that is probable and can be measured reliably, and is adjusted for changes in contingent consideration after the acquisition date. Provisional fair values recognised for business combinations in previous periods are adjusted retrospectively for final fair values determined in the 12 months following the acquisition date. Investments in subsidiaries, joint ventures and associates are accounted for at cost less impairment.

Deferred tax is recognised on differences between the value of assets (other than goodwill) and liabilities recognised in a business combination accounted for using the purchase method and the amounts that can be deducted or assessed for tax, considering the manner in which the carrying amount of the asset or liability is expected to be recovered or settled. The deferred tax recognised is adjusted against goodwill or negative goodwill.

The consolidated group financial statements consist of the financial statements of the parent company Momentive Performance Materials Holdings UK Limited together with all entities controlled by the parent company (its subsidiaries) and the group’s share of its interests in joint ventures and associates.

All financial statements are made up to 31 December 2025. Where necessary, adjustments are made to the financial statements of subsidiaries to bring the accounting policies used into line with those used by other members of the group.

All intra-group transactions, balances and unrealised gains on transactions between group companies are eliminated on consolidation. Unrealised losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred.

Subsidiaries are consolidated in the group’s financial statements from the date that control commences until the date that control ceases.

At the time of approving the financial statements, the directors have a reasonable expectation that the group has adequate resources to continue in operational existence for the foreseeable future. Thus the directors continue to adopt the going concern basis of accounting in preparing the financial statements.

Turnover represents the value of goods and services supplied to customers in the ordinary course of business, net of value added tax, trade discounts, rebates and returns.

Revenue from the sale of manufactured chemical products is recognised at the point in time when control passes to the customer, which is generally on dispatch of the goods or, where contractually agreed, when the goods are made available for collection or delivered.

Revenue from services and ancillary activities is recognised over time as the services are performed, where the outcome can be estimated reliably, by reference to the stage of completion. Where the outcome cannot be estimated reliably, revenue is recognised only to the extent that costs incurred are expected to be recoverable.

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.

Goodwill represents the excess of the cost of acquisition of a business over the fair value of net assets acquired. It is initially recognised as an asset at cost and is subsequently measured at cost less accumulated amortisation and accumulated impairment losses. Goodwill is considered to have a finite useful life and is amortised on a systematic basis over its expected life, which is 10 years.

For the purposes of impairment testing, goodwill is allocated to the cash-generating units expected to benefit from the acquisition. Cash-generating units to which goodwill has been allocated are tested for impairment at least annually, or more frequently when there is an indication that the unit may be impaired. If the recoverable amount of the cash-generating unit is less than the carrying amount of the unit, the impairment loss is allocated first to reduce the carrying amount of any goodwill allocated to the unit and then to the other assets of the unit pro-rata on the basis of the carrying amount of each asset in the unit.

Intangible assets acquired separately from a business are recognised at cost and are subsequently measured at cost less accumulated amortisation and accumulated impairment losses.

Intangible assets acquired on business combinations are recognised separately from goodwill at the acquisition date where it is probable that the expected future economic benefits that are attributable to the asset will flow to the entity and the fair value of the asset can be measured reliably; the intangible asset arises from contractual or other legal rights; and the intangible asset is separable from the entity.

Amortisation is recognised so as to write off the cost or valuation of assets less their residual values over their useful lives on the following bases:

Tangible fixed assets are initially measured at cost and subsequently measured at cost or valuation, net of depreciation and any impairment losses.

Depreciation is recognised so as to write off the cost or valuation of assets less their residual values over their useful lives on the following bases:

The gain or loss arising on the disposal of an asset is determined as the difference between the sale proceeds and the carrying value of the asset, and is recognised in the profit and loss account.

Equity investments are measured at fair value through profit or loss, except for those equity investments that are not publicly traded and whose fair value cannot otherwise be measured reliably, which are recognised at cost less impairment until a reliable measure of fair value becomes available.

In the parent company financial statements, investments in subsidiaries, associates and jointly controlled entities are initially measured at cost and subsequently measured at cost less any accumulated impairment losses.

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

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.

The company values all stock at average cost. More complex products have an overhead added to them using a standard basis of calculation. the more complex the product is to manufacture, the higher the overhead rate attributed.

Full provision is made for obsolete and slow moving items.

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.

The group has elected to apply the provisions of Section 11 ‘Basic Financial Instruments’ and Section 12 ‘Other Financial Instruments Issues’ of FRS 102 to all of its financial instruments.

Financial instruments are recognised in the group's balance sheet when the group becomes party to the contractual provisions of the instrument.

Financial assets and liabilities are offset and 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.

Financial liabilities and equity instruments are classified according to the substance of the contractual arrangements entered into. An equity instrument is any contract that evidences a residual interest in the assets of the group after deducting all of its liabilities.

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.

The tax expense represents the sum of the tax currently payable and deferred tax.

The tax currently payable is based on taxable profit for the year. Taxable profit differs from net profit as reported in the profit and loss account because it excludes items of income or expense that are taxable or deductible in other years and it further excludes items that are never taxable or deductible. The group’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the reporting end date.

Deferred tax liabilities are generally recognised for all timing differences and deferred tax assets are recognised to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits. Such assets and liabilities are not recognised if the timing difference arises from goodwill or from the initial recognition of other assets and liabilities in a transaction that affects neither the tax profit nor the accounting profit.

The carrying amount of deferred tax assets is reviewed at each reporting end date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset is realised. Deferred tax is charged or credited in the profit and loss account, except when it relates to items charged or credited directly to equity, in which case the deferred tax is also dealt with in equity. Deferred tax assets and liabilities are offset if, and only if, there is a legally enforceable right to offset current tax assets and liabilities and the deferred tax assets and liabilities relate to taxes levied by the same tax authority.

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.

Rentals payable under operating leases, including any lease incentives received, are charged to profit or loss on a straight line basis over the term of the relevant lease except where another more systematic basis is more representative of the time pattern in which economic benefits from the leased asset are consumed.

Transactions in currencies other than pounds sterling are recorded at the rates of exchange prevailing at the dates of the transactions. At each reporting end date, monetary assets and liabilities that are denominated in foreign currencies are retranslated at the rates prevailing on the reporting end date. Gains and losses arising on translation in the period are included in profit or loss.

In the application of the group’s accounting policies, the directors are required to make judgements, estimates and assumptions about the carrying amount of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised where the revision affects only that period, or in the period of the revision and future periods where the revision affects both current and future periods.

The following judgements (apart from those involving estimates) have had the most significant effect on amounts recognised in the financial statements.

The useful economic life of assets is kept under annual review. Amendment is made if the estimate of useful life requires change as a result of technological change or the economic use or physical condition of the assets.

The useful life of goodwill is assessed annually to ensure that the estimation of the future productive economic life of the trading assets and liabilities which the goodwill is derived will continue to be deliverable.

Is estimated based upon a calculation of tax timing difference that are likely to arise.

The directors annually calculate on a consistent basis any provisions that may be required in connection with bad debts or stocks that require a reduction in value.

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

Their aggregate remuneration comprised:

The number of directors for whom retirement benefits are accruing under defined contribution schemes amounted to 1 (2024 - 1).

The actual charge for the year can be reconciled to the expected charge for the year based on the profit or loss and the standard rate of tax as follows:

Details of the company's subsidiaries at 31 December 2025 are as follows:

Included within amounts owed to group undertakings is a loan to a fellow subsidiary of £15,081,062 (2024: £7,828,093). The loan is repayable on demand. Interest is charged at the 3m Euribor rate plus a margin of 1.5%.

There is an amount owed to group undertakings of £10,781,625 included in other loans. This is owed under an unsecured Promissory note in favour of Momentive Performance Materials Inc. The full amount is repayable on or before 6 January 2029 and interest accrues at an annual rate of 4.5%

The following are the major deferred tax liabilities and assets recognised by the group and company, and movements thereon:

The deferred tax liability set out above is expected to reverse and relates to accelerated capital allowances that are expected to mature over the life of the assets.

A defined contribution pension scheme is operated for all qualifying employees. The assets of the scheme are held separately from those of the group in an independently administered fund.

Pension contributions outstanding and due at the year-end amounted to £27,342 (2024: £24,517).

At the reporting end date the group had outstanding commitments for future minimum lease payments under non-cancellable operating leases, which fall due as follows:
