The director presents his annual report and financial statements for the year ended 31 December 2025.

The principal activities of the company are design and development of computer controlled data acquisition and measurement systems for use in the oil seismic industry.

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

The auditor, Thomson Cooper, is deemed to be reappointed under section 487(2) of the Companies Act 2006.

The director is responsible for preparing the annual report and the financial statements in accordance with applicable law and regulations.

Company law requires the director to prepare financial statements for each financial year. Under that law the director has 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 director must not approve the financial statements unless he is 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 director is 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 director is 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. He is 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.

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.

We have audited the financial statements of Inova Geophysical (UK) Limited (the 'company') for the year ended 31 December 2025 which comprise the profit and loss account, the balance sheet 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 director's 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 director 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 director is 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 director's report for the financial year for which the financial statements are prepared is consistent with the financial statements; and

• the director's report has 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 director's 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 director's remuneration specified by law are not made; or

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

• the director was not entitled to prepare the financial statements in accordance with the small companies regime and take advantage of the small companies' exemption in preparing the director's report and from the requirement to prepare a strategic report.

As explained more fully in the director's responsibilities statement, the director is 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 director determines 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 director is 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 director either intends to liquidate the company or to cease operations, or has 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.

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.

We considered the opportunities and incentives that may exist within the organisation for fraud and identified the greatest potential for fraud in the following areas: posting of manual journal entries to manipulate financial performance, significant one-off or unusual transactions, and non-compliance with laws and regulations. We discussed these risks with management, gained an understanding of internal controls established to mitigate risks related to fraud, and performed journal entry testing to address the risk of fraud through management override of controls.

We identified areas of laws and regulations that could reasonably be expected to have a material effect on the financial statements from our sector experience through discussion with the officers and other management (as required by the auditing standards).

We reviewed the laws and regulations in areas that directly affect the financial statements including applicable company law and considered the extent of compliance with those laws and regulations as part of our procedures on the related financial statement items.

With the exception of any known or possible non-compliance with relevant and significant laws and regulations, and as required by the auditing standards, our work in respect of these was limited to enquiry of the officers and management of the company.

We communicated identified laws and regulations and potential fraud risks throughout our team and remained alert to any indications of non-compliance or fraud throughout the audit. However the primary responsibility for the prevention and detection of fraud rests with the director.

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 profit and loss account has been prepared on the basis that all operations are continuing operations.

These financial statements have been prepared in accordance with the provisions applicable to companies subject to the small companies regime and in accordance with the provisions of FRS 102 Section 1A - small entities.

Inova Geophysical (UK) Limited is a private company limited by shares incorporated in Scotland. The registered office is 80/2a Commercial Street, Edinburgh, United Kingdom, EH6 6LX.

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

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

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

The company provides R&D services for other group entities, and therefore is closely linked to the Group. There has been no significant impact on the activities of other group companies, and accordingly on this company. We acknowledge that due to the nature of operations no detailed budgets or cash flow forecasts are prepared as a part of management's processes. However, the Group continues to be in strong financial position and the Director believes that the company will be able to continue its activities for the foreseeable future with no changes to the current service agreement in place.true

Based on the above, the Director believes that it is appropriate to prepare the accounts on a going concern basis.

Turnover is recognised to the extent that it is probable that the economic benefits will flow to the company and the turnover can be reliably measured. Turnover is measured as the fair value of the consideration received or receivable, excluding discounts, rebates, value added tax and other sales taxes.

Rendering of services

Turnover from a contract to provide services is in relation to design, development and manufacture of controlled data acquisitions and measurement systems for use in the oil and land seismic industries, recognised in the period in which the services are provided in accordance with the stage of completion of the contract when all of the following conditions are satisfied:

-    the amount of revenue can be measured reliably;

-    it is probable that the company will receive the consideration due under the contract;

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

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

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. The capitalised development costs are subsequently amortised on a straight-line basis over their useful economic lives, which range from 3 to 6 years.

If it is not possible to distinguish between the research phase and the development phase of an internal project, the expenditure is treated as if it were all incurred in the research phase only.

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.

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).

Cash is represented by cash in hand and deposits with financial institutions repayable without penalty on notice of not more than 24 hours. Cash equivalents are highly liquid investments that mature in no more than three months from the date of acquisition and that are readily convertible to known amounts of cash with insignificant risk of change in value.

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 balance sheet when the company becomes party to the contractual provisions of the instrument.

Financial assets and liabilities are offset, with the net amounts presented in the financial statements, when there is a legally enforceable right to set off the recognised amounts and there is an intention to settle on a net basis or to realise the asset and settle the liability simultaneously.

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

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 company after deducting all of its liabilities.

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

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

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

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

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 company’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 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.

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

The actual charge/(credit) 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 company has an unrecognised deferred tax asset of £nil (2024 - £4,734).

Other operating income represents the value of the Research and Development Expenditure Credit (RDEC) claimed in the year.

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

At 31 December 2025 the company was a wholly owned subsidiary of INOVA Geophysical Equipment Limited and so it is exempt from the requirements of FRS102 1A to disclose transactions with other subsidiaries headed by INOVA Geophysical Equipment Limited.

The ultimate controlling party is China National Petroleum Corporation (CNPC) by virtue of its shareholding in BGP Inc. CNPC is a large state-owned enterprise managed by the investment organs authorised by the state and State-owned Assets Supervision and Administration Commission.

The company's immediate parent undertaking is INOVA Geophysical Equipment Limited, a company registered in China. Corporate headquarters: Room 506/5B CNPC Tianjin Tower, No. 83, Second Avenue, TEDA, Tianjin, 300457, P.R. of China.

On 24 October 2023, BGP Inc acquired the minority share and became the sole shareholder of INOVA Geophysical Equipment Limited.
