The directors present their annual report and financial statements for the year ended 31 December 2024.

At 31 December 2024, Owen Oil Tools (U.K.) Limited (also referred to as the "company") is one of the entities within the "Core Laboratories Group". In this context the term "Core Laboratories Group" and "Companies of the Core Laboratories Group" or "Group companies" means companies in which Core Laboratories Inc, either directly or indirectly, has control either through a majority of the voting rights or the right to exercise a controlling influence or to obtain the majority of the benefits and be exposed to the majority of the risks.

The company is principally engaged in the supply and support of ballistic and perforating products to the oil and gas industry. These products are used in all aspects of the life of a well from recovering stuck pipe to completion perforating for effective communication from Wellbore to surface. We provide solutions for multiple well problems where standard non-explosive options are ineffective.

The development and position of the company, is discussed in the Group’s annual report and Form 10-K of its ultimate parent, Core Laboratories Inc.

The results for the company show a loss before taxation of £884,052 (2023: £653,011) and turnover of £7,331,996 (2023: £9,755,029). The company had cash at bank and in hand of £9,899 (2023: £2,136) at 31 December 2024.

The loss for the financial year amounted to £884,052 (2023: £653.011) and was transferred to profit and loss account.

The financial position of the company is set out on page 9.

The directors do not propose payment of a dividend (2023: nil).

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

At the financial year-end, the Company had net current assets of £2,706,199, net assets of £2,758,226, cash balance of £9,899 and loss for the year then ended of £884,052. The Company has no external borrowings. However the financial statements have been prepared on a going concern basis which the Directors consider to be appropriate for the following reasons.

At the date of signing these financial statements, the Company has continued to trade without interruption despite ongoing global conflcits impacting economies around the world. The director believes a long period of sustained higher oil prices may negatively affect demand for some of the Company’s services. The nature of the Company’s business is such that there is reasonable visibility as to order books in the next 12 months. Beyond this, there is expected to be greater unpredictable variation in the value and timing of cash inflows from customers.

As a result, the directors have prepared projected cash flow information for the twelve months from the date of approval of these financial statements. This includes an additional severe but reasonably plausible downside scenario in which revenues are restricted through lower demand for services throughout the forecasted period. It also includes a reduction of the scale of the Company via reduction in costs should this be required.

The company’s operations are primarily in the UK which exposes the company to financial risks that include foreign exchange risk, credit risk and interest rate risk.

(a)    Foreign exchange risk

The company is exposed to foreign currency risk on transactions where sales, purchases and borrowings which are in currencies other than the company’s functional currency. Inventory products are purchased from an affiliated manufacturing company in Godley, Texas. These transactions along with other intercompany balances are considered the main foreign exchange risk as they are maintained in currencies other than the company’s functional currency - primarily US Dollar balances. Management believe that the company’s exposure to foreign exchange risk is manageable and therefore it does not enter into forward exchange contracts.

(b)    Credit risk

The company has no significant concentrations of credit risk. The company has implemented policies that require appropriate credit checks on potential customers before sales commence. The company has implemented policies which require only minimum balances to be held locally in cash and deposits with financial institutions.

(c)    Interest rate risk

The company had interest bearing assets and liabilities during the year. Interest rate risk arises from the fluctuations in market rates, which may have a negative effect on current and future developments of the company. Management believe that the company’s exposure to interest rate risk is minimal and therefore it does not enter into hedging arrangements.

All directors of the company are covered under our directors and officers insurance policy which is a qualifying third party indemnity provision. This provision was in force during the financial year and also at the date of approval of the financial statements.

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.

Pursuant to section 487 of the Companies Act 2006, the auditor will be deemed to be reappointed and Azets Audit Services will therefore continue in office.

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;

• 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 Owen Oil Tools (U.K.) Limited (the 'company') for the year ended 31 December 2024 which comprise the statement of comprehensive income, the statement of financial position, the statement of changes in equity 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 2024 and of its loss 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 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.

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' exemption in preparing the directors' report and from the requirement to prepare a strategic report.

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.

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.

Extent to which 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 and on the Financial Reporting Council’s website, to detect material misstatements in respect of irregularities, including fraud.

We obtain and update our understanding of the entity, its activities, its control environment, and likely future developments, including in relation to the legal and regulatory framework applicable and how the entity is complying with that framework.  Based on this understanding, we identify and assess the risks of material misstatement of the financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion.  This includes consideration of the risk of acts by the entity that were contrary to applicable laws and regulations, including fraud.

In response to the risk of irregularities and non-compliance with laws and regulations, including fraud, we designed procedures which included:

• Enquiry of management and those charged with governance around actual and potential litigation and claims as well as actual, suspected and alleged fraud; 

• Reviewing minutes of meetings of those charged with governance;

• Assessing the extent of compliance with the laws and regulations considered to have a direct material effect on the financial statements or the operations of the company through enquiry and inspection; 

• Reviewing financial statement disclosures and testing to supporting documentation to assess compliance with applicable laws and regulations;

• Performing audit work over the risk of management bias and override of controls, including testing of journal entries and other adjustments for appropriateness, evaluating the business rationale of significant transactions outside the normal course of business and reviewing accounting estimates for indicators of potential bias. 

Because of the inherent limitations of an audit, there is a risk that we will not detect all irregularities, including those leading to a material misstatement in the financial statements or non-compliance with regulation.  This risk increases the more that compliance with a law or regulation is removed from the events and transactions reflected in the financial statements, as we will be less likely to become aware of instances of non-compliance.  The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

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 statement of comprehensive income 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.

Owen Oil Tools (U.K.) Limited (“the company”) is principally engaged in the supply, support and manufacture of ballistic and perforating products to the oil and gas industry. The company is a private company limited by shares and is incorporated and domiciled in England. The registered number is 03691954 and the registered address is 13th Floor, One Angel Court, London, EC2R 7HJ.

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.

This 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:

• 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.

The financial statements of the company are consolidated in the financial statements of Core Laboratories Inc. These consolidated financial statements are available from its registered office, 6316 Windfern Road, Houston, TX 77040, United States.

At the financial year-end, the Company had net current assets of £2,706,199, net assets of £2,758,226, cash balance of £9,899 and loss for the year then ended of £884,052. The Company has no external borrowings. However the financial statements have been prepared on a going concern basis which the Directors consider to be appropriate for the following reasons.true

At the date of signing these financial statements, the Company has continued to trade without interruption despite ongoing global conflcits impacting economies around the world. The director believes a long period of sustained higher oil prices may negatively affect demand for some of the Company’s services. The nature of the Company’s business is such that there is reasonable visibility as to order books in the next 12 months. Beyond this, there is expected to be greater unpredictable variation in the value and timing of cash inflows from customers.

As a result, the directors have prepared projected cash flow information for the twelve months from the date of approval of these financial statements. This includes an additional severe but reasonably plausible downside scenario in which revenues are restricted through lower demand for services throughout the forecasted period. It also includes a reduction of the scale of the Company via reduction in costs should this be required.

This assessment is dependent on the Company’s ultimate parent, Core Laboratories Inc not seeking repayment of the amounts currently due to the group, which at 31 December 2024 amounted to £1,773,510. Core Laboratories Inc has indicated its intention to continue to make available such funds as are needed by the Company, and that it does not intend to seek repayment of the amounts due at the balance sheet date, for the period covered by the forecasts. The directors have considered the financial position of the group, and they have considered that the ultimate parent company has the ability to continue with this support.

As with any company placing reliance on other group entities for financial support, the directors acknowledge that there can be no certainty that this support will continue although, at the date of approval of these financial statements, they have no reason to believe that it will not do so.

Consequently, the directors are confident that the Company will have sufficient funds to continue to meet its liabilities as they fall due for at least twelve months from the date of approval of the financial statements and therefore have prepared the financial statements on a going concern basis.

Turnover represents the value of goods and services stated net of value added tax and trade discounts.

The company recognises revenue when (a) the significant risks and rewards of ownership have been transferred to the customer, including where they are based on contractual rates; (b) the company retains no continuing involvement or control over the goods; (c) the amount of revenue can be measured reliably; and (d) it is probable that future economic benefit will flow to the entity.

Rental income from operating leases (net of any incentives given to the lessees) is recognised on a straight-line basis over the term of the lease.

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). 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.

Recoverable amount is the higher of fair value less costs to sell and value in use. In assessing value in use, the estimated future cash flows are discounted to their present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the asset for which the estimates of future cash flows have not been adjusted.

If the recoverable amount of an asset (or cash-generating unit) is estimated to be less than its carrying amount, the carrying amount of the asset (or cash-generating unit) is reduced to its recoverable amount. An impairment loss is recognised immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the impairment loss is treated as a revaluation decrease.

Recognised impairment losses are reversed if, and only if, the reasons for the impairment loss have ceased to apply. Where an impairment loss subsequently reverses, the carrying amount of the asset (or cash-generating unit) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognised for the asset (or cash-generating unit) in prior years. A reversal of an impairment loss is recognised immediately in profit or loss, unless the relevant asset is carried at a revalued amount, in which case the reversal of the impairment loss is treated as a revaluation increase.

Stocks are stated at the lower of cost and estimated selling price less costs to complete and sell. Cost is based on the first-in first out principle and includes expenditure incurred in acquiring the stocks, production or conversion costs and other costs in bringing them to their existing location and condition. In the case of manufactured stocks and work in progress, cost includes an appropriate share of overheads based on normal operating capacity.

Stock in transit is recognised at the point of shipping as this is when the risks and rewards of inventory pass to the company from its fellow group entity which provides all stock.

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 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.

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, 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.

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.

Current tax is the amount of income tax payable in respect of taxable profit for the year or prior years. Tax is calculated on the basis of tax rates and laws that have been enacted or substantively enacted by the period end.

Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulation is subject to interpretation. It establishes provision where appropriate on the basis of amounts expected to be paid to the tax authorities.

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 financial statements.

Deferred tax is recognised on all timing differences at the reporting date except for certain exceptions. Unrelieved tax losses and other deferred tax assets are only recognised when it is probable that they will be recovered against the reversal of deferred tax liabilities or future taxable profits.

Deferred tax is measured using tax rates and laws that have been enacted or substantively enacted by the period end and that are expected to apply to the reversal of the timing difference.

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.

The company provides pensions to all employees through a defined contribution pension scheme. The assets of the scheme are held separately from those of the company. Contributions are charged to the profit and loss account as they become due and payable.

Core Laboratories Inc grants restricted share awards under a share incentive plan, the 2007 Long-Term Incentive Plan (the "Plan"). Awards under the Plan have been made through a compensation program, the Restricted Share Award Program ("RSAP").

Core Laboratories Inc issues shares from either treasury stock or authorized shares upon the lapsing of vesting restrictions on restricted stock awards. All restricted share awards are equity settled.

Under the RSAP certain Owen Oil Tools (U.K.) Limited employees and directors were awarded grants. Each of these grants has a vesting period of principally five years and vest on an annual basis. There are no performance accelerators for early vesting for these awards. Awards under the RSAP are classified as an equity award and recorded at the grant-date fair value and the compensation expense is being recognized over the expected life of the award. A charge is booked to the income statement as an employee benefit expense for the fair value of share awards expected to vest, accrued over the vesting period. The corresponding credit is initially taken to retained earnings, which is subsequently reversed on the recognition of the group recharge in respect of the share-based payment expense. All share awards are at a £nil exercise price and the fair value of the share awards is the grant-date market value on the date of the award.

Rentals relating to assets held under operating leases are charged to the profit and loss account as incurred.

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.

Interest payable and similar expense

Interest payable and similar expenses include interest payable on loan notes and net foreign losses. Interest payable is recognised in profit or loss as they accrue, using the effective interest method.

Interest receivable and similar income

Interest receivable and similar income includes interest receivable on funds invested, intercompany loans and net foreign exchange gains. Interest income is recognised in profit or loss as it accrues, using the effective interest method.

Estimates and judgements are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. The company makes an estimate when assessing stock provision, useful economic lives of tangible fixed assets and recoverability of debtors. There are no material judgements.

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

Their aggregate remuneration comprised:

The directors did not receive nor waive any emoluments in respect of their services to the company during the current or prior year.

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

The main rate of corporation tax increased from 19% to 25% on 1 April 2023. This increase in rate will have an impact on the company’s future tax charges. The company’s deferred tax balances as at 31 December 2023 and 2024 have been calculated based on the rate of 25%, however there is no deferred tax balance recognised in 2023 or 2024 (see note 14).

Raw materials, consumables and changes in finished goods and work in progress recognised as cost of sales in the year amounted to £6,474,729 (2023: £8,674,616).

Amounts owed by group undertakings are interest free, unsecured and repayable on demand.

Amounts owed to group undertakings are unsecured and repayable on demand. Amounts are interest free with the exception of the amounts owed to Core Laboratories Inc. which bear an interest rate based on SOFR. The amount subject to interest was £1,773,510 at 31 December 2024 (2023: £4,645,193).

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

There are unrecognised deferred tax assets of £3,665 (2023: £3,970) in respect of fixed asset timing differences as it is not probable that they will be recovered against the reversal of deferred tax liabilities or future taxable profits.

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. There are no oustanding premiums at the year end (2023: £nil)

Certain Owen Oil Tools (U.K.) Limited employees and directors hold share awards in the ultimate parent company at 31 December 2024, Core Laboratories Inc.

Awards have been made through a compensation program, the Restricted Share Award Program ("RSAP"). The charge in the profit and loss account for this program is £340 (2023: £4,490). All long-term incentive compensation is exclusively in the form of restricted share awards and no share options were granted during 2024 (2023: nil).

The terms and conditions of the grants are as follows:

The non-vested restricted share awards outstanding as of 31 December 2024 and changes during the year were as follows:

(a) Each of the RSAP grants has a vesting period of principally five years and vest on an annual basis. There are no performance accelerators for early vesting for these awards. Awards under the RSAP are classified as an equity award and recorded at the grant-date fair value and the compensation expense is being recognized over the expected life of the award. All share awards are at a £nil exercise price and the fair value of the share awards is the grant-date market value on the date of the award.

There is a single class of ordinary shares. There are no restrictions on the distribution of dividends and the repayment of capital.

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

The company had no other off-balance sheet arrangements.

The company has taken advantage of the exemption available under FRS 102 ‘Related party’ disclosure not to disclose transactions with other group companies being a wholly owned subsidiary of Core Laboratories Inc. Related party disclosures are included in the financial statements for that group.

The immediate parent undertaking is Core Laboratories (U.K.) Limited. The registered address of Core Laboratories (U.K.) Limited is 13th Floor, One Angel Court, London, United Kngdom, EC3R 7HJ.

On 1 May 2023, the group under went a redomestication process with the aim of simplifying the group structure. The former ultimate parent company, Core Laboratories N.V., merged with Core Laboratories Luxembourg S.A (another group company). Subsequently, Core Laboratories Luxembourg S.A was redomesticated into Delaware, USA. This company then changed name to become Core Laboratories Inc. and therefore the new ultimate parent undertaking and controlling party.

At 31 December 2024 the ultimate parent undertaking and controlling party is Core Laboratories Inc., a company incorporated in The United States of America.

Core Laboratories Inc. is the parent undertaking of the largest and smallest group in which the results of the company are consolidated. The consolidated financial statements of Core Laboratories Inc. are available from 6316 Windfern Road, Houston, TX 77040, United States.
