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

SEM is operating as an intergroup manufacturing company and focuses on the intercompany business.

The year 2025 continued with its consolidation and a tendency towards the new series of permanent magnet synchronous servo motors. The product orders continued at a comparable level to the year before but with larger peaks and higher requirement of flexibility.

The material availability in the supply chain correspondingly continued to settle and there was less variation in material prices compared to recent years. Few key materials require higher effort and time to precure. The global political uncertainty is an increasing threat to potential future market restrictions implied by our intercompany business.

The new series of synchronous servo motors could be completed, and the last motor been launched into the market. The volume production of the new series of synchronous servo motors continued to steadily grow with some peak demands during the ramp-up.

KPIs continue to be the driving factor to further improve and optimise the operational performance and achieving SEM Limited’s business targets.

SEM is continuing to invest in its structured performance development process for all staff, raising and developing employees’ competencies and ensuring adequate succession planning.

With the continuing ramp-up of the new synchronous servo motors processes are required to be optimized and fine-tuned. It is planned to introduce the environmental system based on ISO 14001 during 2026 with set targets for reduction of energy usage by 2030.

Outlook and business strategy

Increasing resilience, high level of flexibility was and still is SEM’s focus to improve robustness for the continuing market volatility. The newly introduced compact servo motor range continues to be distributed in higher competitive markets. Involving its highly motivated staff on all levels into the structured policy-deployment is further increasing the ability to react to the increasing complexity of changing markets and continues to be part of this journey to contribute to the group’s future success.

On behalf of the board

The Directors present their report and financial statements for the year ended 31 December 2025. Reference should also be made to the Strategic report.

The principal activity of the company continued to be that of the design and manufacture of electric synchronous and asynchronous motors and associated equipment.

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

The directors do not recommend payment of an ordinary dividend.

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

The company's research and development team continue to contribute to group led projects on motor performance.

As SEM Limited continues to operate as an intercompany manufacturing company, the sales made are wholly within the group. There is regular communication as to the volume and type of products required for the intercompany business. Good supplier relationships are fostered by the directors and management and it is ensured that suppliers are paid within their terms.

The auditor, Friend-James Limited, is deemed to be reappointed under section 487(2) of the Companies Act 2006.

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 company’s auditor 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 company’s auditor is aware of that information.

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

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 company and of the profit or loss of the company 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; and

• prepare the financial statements on the going concern basis unless it is inappropriate to presume that the company will continue in business.

The directors are responsible for keeping adequate accounting records that are sufficient to show and explain the company’s transactions and disclose with reasonable accuracy at any time the financial position of the 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 company and hence for taking reasonable steps for the prevention and detection of fraud and other irregularities.

We have audited the financial statements of SEM Limited (the 'company') for the year ended 31 December 2025 which comprise the statement of comprehensive income, the statement of financial position, the statement of changes in equity, the 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 company's affairs as at 31 December 2025 and of its 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 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 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 company and its 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, or returns adequate for our audit have not been received from branches not visited by us; or

• the 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 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 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.

Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below:

Our approach to identifying and assessing the risks of material misstatement in respect of irregularities, including fraud and non-compliance with laws and regulations, was as follows:

•the engagement partner ensured that the engagement team collectively had the appropriate competence, capabilities and skills to identify or recognise non-compliance with applicable laws and regulations;

•we identified the laws and regulations applicable to the company through discussions with directors and other management, and from our commercial knowledge and experience of the sector in which the company operates;

•we focused on specific laws and regulations which we considered may have a direct material effect on the financial statements or the operations of the company, including the Companies Act 2006, relevant UK taxation legislation, the Data Protection Act, the Bribery Act 2010, relevant employment laws and environmental and health and safety legislation;

•we assessed the extent of compliance with the laws and regulations identified above through making enquiries of management and inspecting legal correspondence; and

•identified laws and regulations were communicated within the audit team regularly and the team remained alert to instances of non-compliance throughout the audit.

We assessed the susceptibility of the company’s financial statements to material misstatement, including obtaining an understanding of how fraud might occur, by:

•making enquiries of management as to where they considered there was susceptibility to fraud, their knowledge of actual, suspected and alleged fraud;

•considering the internal controls in place to mitigate risks of fraud and non-compliance with laws and regulations.

To address the risk of fraud through management bias and override of controls, we:

• performed analytical procedures to identify any unusual or unexpected relationships;

• tested journal entries to identify unusual transactions;

• assessed whether judgements and assumptions made in determining the accounting estimates set out in Note 3 were indicative of potential bias;

• investigated the rationale behind significant or unusual transactions; and

In response to the risk of irregularities and non-compliance with laws and regulations, we designed procedures which included, but were not limited to:

• agreeing financial statement disclosures to underlying supporting documentation;

• reading the minutes of meetings of those charged with governance;

• enquiring of management as to actual and potential litigation and claims;

• reviewing correspondence with HMRC and the company’s legal advisors.

There are inherent limitations in our audit procedures described above. The more removed that laws and regulations are from financial transactions, the less likely it is that we would become aware of non-compliance. Auditing standards also limit the audit procedures required to identify non-compliance with laws and regulations to enquiry of the directors and other management and the inspection of regulatory and legal correspondence, if any.

Material misstatements that arise due to fraud can be harder to detect than those that arise from error as they may involve deliberate concealment or collusion.

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 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 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 company and the company's members as a body, for our audit work, for this report, or for the opinions we have formed.

The income statement has been prepared on the basis that all operations are continuing operations.

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

SEM Limited is a private company limited by shares incorporated in England and Wales. The registered office is One Hundred House, Brunel Way, Dartford, DA1 5TH.

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.

Atruet 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. Thus the directors continue to adopt the going concern basis of accounting in preparing the financial statements.

Turnover is recognised at the fair value of the consideration received or receivable for goods provided in the normal course of business, and is shown net of VAT and other sales related taxes.

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.

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 credited or charged to profit or loss.

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.

Investment in unlisted company shares, which have been classified as fixed asset investments as the company intends to hold them on a continual basis, are remeasured at market value at each balance sheet date. Gains and losses on remeasurement are recognised in the profit and loss account for the period.

An associate is an entity, being neither a subsidiary nor a joint venture, in which the company holds a long-term interest and where the company has significant influence. The company considers that it has significant influence where it has the power to participate in the financial and operating decisions of the associate.

At each reporting period end date, the company reviews the carrying amounts of its tangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists, the recoverable amount of the asset is estimated in order to determine the extent of the impairment loss (if any). Where it is not possible to estimate the recoverable amount of an individual asset, the company estimates the recoverable amount of the cash-generating unit to which the asset belongs.

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.

Cost is calculated using the weighted moving average price method for purchased items and 'standard price' for manufactured items.

At each reporting date, inventories are assessed for impairment and a stock provision is applied based on a ten year scappage model, with the impairment loss recognised immediately in the profit and loss account.

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 company 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 company's statement of financial position 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.

Other financial assets, including investments in equity instruments which are not subsidiaries, associates or joint ventures, are initially measured at fair value, which is normally the transaction price. Such assets are subsequently carried at fair value and the changes in fair value are recognised in profit or loss, except that investments in equity instruments that are not publicly traded and whose fair values cannot be measured reliably are measured at cost less impairment.

Trade debtors, loans and other receivables that have fixed or determinable payments that are not quoted in an active market are classified as 'loans and receivables'. Loans and receivables are measured at amortised cost using the effective interest method, less any impairment.

Financial assets, other than those held at fair value through profit and loss, are assessed for indicators of impairment at each reporting end date.

Financial assets are impaired where there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows have been affected. If an asset is impaired, the impairment loss is the difference between the carrying amount and the present value of the estimated cash flows discounted at the asset’s original effective interest rate. The impairment loss is recognised in profit or loss.

Financial assets are derecognised only when the contractual rights to the cash flows from the asset expire or are settled, or when the company transfers the financial asset and substantially all the risks and rewards of ownership to another entity, or if some significant risks and rewards of ownership are retained but control of the asset has transferred to another party that is able to sell the asset in its entirety to an unrelated third party.

Basic financial liabilities 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 receipts discounted at a market rate of interest. Financial liabilities classified as payable within one year are not amortised.

Derivatives at group level, including interest rate swaps and forward foreign exchange contracts, are not basic financial instruments. Derivatives are initially recognised at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value. Changes in the fair value of derivatives are recognised in profit or loss in finance costs or finance income as appropriate, unless hedge accounting is applied and the hedge is a cash flow hedge.

Debt instruments that do not meet the conditions in FRS 102 paragraph 11.9 are subsequently measured at fair value through profit or loss. Debt instruments may be designated as being measured at fair value through profit or loss to eliminate or reduce an accounting mismatch or if the instruments are measured and their performance evaluated on a fair value basis in accordance with a documented risk management or investment strategy.

Financial liabilities are derecognised when the company’s contractual obligations expire or are discharged or cancelled.

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.

Changes in the fair value of derivatives that are designated and qualify as fair value hedges are recognised in profit or loss immediately, together with any changes in the fair value of the hedged asset or liability that are attributable to the hedged risk.

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 income statement 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 company’s liability for current tax is calculated using tax rates that have been enacted or substantively enacted by the reporting end date.

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.

Monetary assets and liabilities denominated in foreign currencies are translated into sterling at the rates of exchange ruling at the statement of financial position date. Transactions in foreign currencies are recorded at the rate ruling at the date of the transaction. All realised gains and losses, along with unrealised losses, are taken to the statement of comprehensive income.

In the application of the company’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.

The estimates and assumptions which have a significant risk of causing a material adjustment to the carrying amount of assets and liabilities are as follows:

A stock provision is applied based on a ten year scrappage model.

An analysis of the company's turnover is as follows:

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

Their aggregate remuneration comprised:

Investment income includes the following:

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:

The carrying value of land is:

An impairment decrease of £78.068 (2024: £360,659) was recognised in cost of sales during the year, due to a reduction in the level of slow moving and obsolete stock.

Deferred tax assets and liabilities are offset where the company has a legally enforceable right to do so. The following is the analysis of the deferred tax balances (after offset) for financial reporting purposes:

The deferred tax liability set out above is expected to reverse within 12 months and relates to accelerated capital allowances that are expected to mature within the same period.

The company operates a defined contribution pension scheme for all qualifying employees. The assets of the scheme are held separately from those of the company in an independently administered fund.

Ordinary shares are entitled to vote, receive dividends and distributions under all circumstances.

Amounts contracted for but not provided in the financial statements:

During the year the company entered into the following transactions with related parties:

The immediate parent company is Westec Holding Company Limited, a company registered in England and Wales, which is ultimately owned by Dr Johannes Heidenhain - Stiftung GmbH, a company registered in Germany.
