DIRECTORS' RESPONSIBILITIES STATEMENT
FOR THE YEAR ENDED 31 DECEMBER 2025

The directors are responsible for preparing the Directors' 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 applicable law and United Kingdom Accounting Standards (United Kingdom Generally Accepted Accounting Practice), including Financial Reporting Standard 101 ‘Reduced Disclosure Framework’ ("FRS 101"). 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 in accordance with FRS 101 and then apply them consistently;

make judgments and accounting estimates that are reasonable and prudent;

state whether applicable UK Accounting Standards, including FRS 101, have been followed, subject to any material departures disclosed and explained in the financial statements;
present information, including accounting policies, in a manner that provides relevant, reliable, comparable and understandable information;
provide additional disclosures when compliance with the specific requirements in FRS 101 are insufficient to enable users to understand the impact of particular transactions, other events and conditions on the Company financial position and financial performance;

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 to enable them to ensure that the financial statements  comply with the Companies Act 2006They 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.

Under applicable law and regulations, the directors are also responsible for preparing a Directors' Report that comply with that law and those regulations.

The directors are responsible for the maintenance and integrity of the corporate and financial information included on the Company's website. Legislation in the United Kingdom governing the preparation and dissemination of and other information included in Directors' Reports may differ from legislation in other jurisdictions.

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF WIND RIVER UK LIMITED
FOR THE YEAR ENDED 31 DECEMBER 2025

Opinion


We have audited the financial statements of Wind River UK Limited (the 'Company') for the year ended 31 December 2025, which comprise the Profit and Loss Account, the Balance Sheet, the Statement of Changes in Equity and the related notes, including a summary of significant accounting policiesThe financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 101 ‘Reduced Disclosure Framework’ (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 Auditors' 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 United Kingdom, including the Financial Reporting Council'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 Auditors' Report thereon. The directors are responsible for the other information contained within the Annual ReportOur 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.

WIND RIVER UK LIMITED

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF WIND RIVER UK LIMITED (CONTINUED)
FOR THE YEAR ENDED 31 DECEMBER 2025

Opinion on other matters prescribed by the Companies Act 2006
 

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


the information given in the Directors' Report for the financial year for which the financial statements are prepared is consistent with the financial statements; and
the Directors' Report has been prepared in accordance with applicable legal requirements.


Matters on which we are required to report by exception
 

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 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; or
the directors were not entitled to prepare the financial statements in accordance with the small companies regime and take advantage of the small companies' exemptions in preparing the Directors' Report and from the requirement to prepare a Strategic Report.


Responsibilities of directors
 

As explained more fully in the Directors' Responsibilities Statement set out on page 3, 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.

WIND RIVER UK LIMITED

INDEPENDENT AUDITORS' REPORT TO THE MEMBERS OF WIND RIVER UK LIMITED (CONTINUED)
FOR THE YEAR ENDED 31 DECEMBER 2025

Auditors' responsibilities for the audit of the financial statements
 

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 Auditors' 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.

Explanation as to what extent the audit was considered capable of detecting irregularities, including fraud.

Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect irregularities, including fraud. The risk of not detecting a material misstatement due to fraud is higher than the risk of not detecting one resulting from error, as fraud may involve deliberate concealment by, for example, forgery or intentional misrepresentations, or through collusion. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below. However, the primary responsibility for the prevention and detection of fraud rests with both those charged with governance of the entity and management.

Our approach was as follows:

We obtained an understanding of the legal and regulatory frameworks that are applicable to the company and determined that the most significant are FRS 101, Companies Act 2006, and United Kingdom direct and indirect tax regulations. In addition, the company must comply with operational and employment laws and regulations including health and safety regulations, environmental regulations and GDPR. 
We understood how the company is complying with those frameworks by making enquiries of management and senior finance personnel and gaining an understanding of the entity level controls of the company in respect of these areas and the controls in place to reduce opportunity for fraudulent transactions. 
We assessed the susceptibility of the company’s financial statements to material misstatement, including how fraud might occur through inquiry of management and senior finance personnel to understand where they considered there was susceptibility to fraud. We considered the procedures and controls that the Company has established to address risks identified, or that otherwise prevent, deter and detect fraud and gained an understanding as to how those procedures and controls are implemented and monitored. 
Where available we read minutes of meetings of those charged with governance.
We read financial statements disclosures and tested to supporting documentation to assess compliance with applicable laws and regulations. 
We audited the risk of management override of controls, including through testing journal entries and other adjustments for appropriateness. We also audited the risk of improper revenue recognition through performing audit procedures around revenue cut-off.
We challenged judgements made by management. This included corroborating the inputs and considering contradictory evidence.
Based on this understanding we designed our audit procedures to identify non-compliance with such laws and regulations. Our procedures involved reading board minutes to identify any non-compliance with laws and regulations and enquiries of management.


A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council's website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our Auditors' Report.

2.4

Foreign currency translation

Functional and presentation currency

The Company's functional and presentational currency is Sterling (£).

Transactions and balances

Foreign currency transactions are translated into the functional currency using the spot exchange rates at the dates of the transactions.

At each period-end foreign currency monetary items are translated using the closing rate. Non-monetary items measured at historical cost are translated using the exchange rate at the date of the transaction and non-monetary items measured at fair value are measured using the exchange rate when fair value was determined.

Foreign exchange gains and losses resulting from the settlement of transactions and from the translation at period-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in profit or loss.

Foreign exchange gains and losses that relate to borrowings and cash and cash equivalents are presented in the Profit and Loss Account within 'administrative expenses'.

 
2.5

Revenue

Revenue 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.

Revenue from products (perpetual software licences, time-based software licences and fees for standalone software) and production licences is generally recognised at a point in time when made available to the customer. 

Revenue from subscriptions to software licences (including post-contract support) and maintenance for software contracts are recognised on a rateable basis over the contract term. 

Revenue allocated to professional services and training services is recognised as the services are delivered to the customer. Professional services include design, consulting and deployment services. 

Revenue from fixed-price professional service contracts is recognized over time as performance obligations are satisfied. Progress is measured using an input method, and revenue is recognized on a percentage of completion basis reflecting the stage of completion at the reporting date.

Where a customer contract contains more than one performance obligation, the consideration is allocated between the different elements on a relative fair value basis based on the Standalone Selling Price of each obligation. The revenue allocated to each element is recognised as outlined above.

2.Material accounting policy information (continued)


2.5
Revenue (continued)

From time to time, the Company enters into pricing agreements with its customers that provide for price reductions. In these instances, revenue is recognised based on the agreed-upon price at the time of delivery.

The Company is reimbursed for certain costs incurred in connection with the above services and for support to the group's delivery of the above services. The Company is reimbursed including a commission, and intercompany revenue is recognised as the costs are incurred.

The Company does not expect to have any contracts where the period between the transfer of the promised goods or services to the customer and payment by the customer exceeds one year. As a consequence, the Company does not adjust any of the transaction prices for the time value of money.

Contract assets are primarily comprised of unbilled receivables, which consist of amounts related to the company’s unconditional right to consideration for completed performance obligations that have not been invoiced.
 
 
2.6

Interest receivable and similar income

Interest income is recognised in profit or loss using the effective interest method.

 
2.7

Interest payable and similar expenses

Finance costs are charged to profit or loss over the term of the debt using the effective interest method so that the amount charged is at a constant rate on the carrying amount.

 
2.8

Pensions

Defined contribution pension plan

The Company operates a defined contribution plan for its employees. A defined contribution plan is a pension plan under which the Company pays fixed contributions into a separate entity. Once the contributions have been paid the Company has no further payment obligations.

The contributions are recognised as an expense in profit or loss when they fall due. Amounts not paid are shown in accruals as a liability in the Balance Sheet. The assets of the scheme are held separately from those of the Company in independently administered fund.

2.9

Tangible fixed assets

Tangible fixed assets under the cost model are stated at historical cost less accumulated depreciation and any accumulated impairment losses. Historical cost includes expenditure that is directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management.

Depreciation is charged so as to allocate the cost of assets less their residual value over their estimated useful lives, using the straight-line method.

Depreciation is provided on the following basis:

Plant and machinery
-
5 - 7 years
Fixtures and fittings
-
5 - 7 years
Computer equipment
-
2 - 3 years

The assets' residual values, useful lives and depreciation methods are reviewed, and adjusted prospectively if appropriate, or if there is an indication of a significant change since the last reporting date.

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognised in profit or loss.

Where there are indicators of impairment of individual assets, the company performs impairment tests based on fair value less costs to sell or a value in use calculation. The fair value less costs to sell calculation is based on available data from binding sales transactions in an arm’s length transaction on similar assets or observable market prices less incremental costs for disposing of the asset. The value in use calculation is based on a discounted cash flow model.

Subsequent to initial recognition, tangible fixed assets are stated at cost less accumulated depreciation and accumulated impairment.

 
2.10

Debtors

Short-term debtors are measured at transaction price, less any impairment under the expected credit loss model. Loans receivable are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method, less any impairment.

 
2.11

Creditors

Creditors are obligations to pay for goods or services that have been acquired in the ordinary course of business from suppliers.

Creditors are recognised initially at fair value and subsequently measured at amortised cost using the effective interest method.

2.12

Taxation

The tax expense for the year comprises current and deferred tax. Tax is recognised in the profit and loss account, except that a charge attributable to an item of income and expense recognised as other comprehensive income or to an item recognised directly in equity is also recognised in other comprehensive income or directly in equity respectively.

Current tax is the amount of income tax payable in respect of taxable profit for the year or prior years.

The current income tax charge is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the balance sheet date in the countries where the Company operates and generates income.

Deferred tax arises from timing differences that are differences between taxable profits and total comprehensive income as stated in the financial statements. These timing differences arise from the inclusion of income and expenses in tax assessments in periods different from those in which they are recognised in the financial statements.

Deferred tax balances are recognised in respect of all timing differences that have originated but not reversed by the balance sheet date, except that:
 
The recognition of deferred tax assets is limited to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits; and
Any deferred tax balances are reversed if and when all conditions for retaining associated tax allowances have been met.

Deferred tax balances are not recognised in respect of permanent differences except in respect of business combinations, when deferred tax is recognised on the differences between the fair values of assets acquired and the future tax deductions available for them and the differences between the fair values of liabilities acquired and the amount that will be assessed for tax. Deferred tax is determined using tax rates and laws that have been enacted or substantively enacted by the balance sheet date.

Judgments in applying accounting policies and key sources of estimation uncertainty

The preparation of the financial statements requires management to make judgements, estimates and assumptions that affect the reported amounts in the financial statements. Management continually evaluates its judgements and estimates in relation to assets, liabilities, contingent liabilities, revenue and expenses. Management bases its judgements, estimates and assumptions on historical experience and on other various factors, including expectations of future events, that management believes to be reasonable under the circumstances. The judgements, estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are discussed below:

Revenue recognition

Contracts with customers often include promises to transfer multiple products and services to a customer. Determining whether products and services are considered distinct performance obligations that should be accounted for separately or together may require significant judgement. Judgement is required to determine whether a software licence is considered distinct and accounted for separately, or not distinct and accounted for together with the services and recognised over time.

Judgement is required to determine the Standalone Selling Price ("SSP") for each distinct performance obligation. The Company uses a range of amounts to estimate the SSP for items that are not sold separately. In instances where the SSP is not directly observable, the Company determines the SSP using information that may include other observable inputs or the residual approach. The Company typically has more than one SSP for individual products and services due to the stratification of those products and services by customer classes and circumstances. In these instances, the Company may use information such as the size and type of customer in determining the SSP.
