NOTES TO THE FINANCIAL STATEMENTS

FOR THE FINANCIAL YEAR ENDED 31 DECEMBER 2024
1. Accounting policies

The principal accounting policies are summarised below. They have all been applied consistently throughout the financial year and to the preceding financial year, unless otherwise stated.

General information and basis of accounting

SPEX Corporate Holdings Limited (the Company) is a private company, limited by shares, incorporated in the United Kingdom under the Companies Act 2006 and is registered in Scotland. The address of the Company's registered office is Blackwood House, Union Grove Lane, Aberdeen, AB10 6XU, Scotland, United Kingdom. The trading address is First Floor, Unit 2, Dunnottar House, Howe Moss Drive, Kirkhill Industrial Estate, Aberdeen, AB21 0FN.

The financial statements have been prepared under the historical cost convention, and in accordance with Section 1A of Financial Reporting Standard 102 (FRS 102) ‘The Financial Reporting Standard applicable in the UK and Republic of Ireland’ issued by the Financial Reporting Council and the requirements of the Companies Act 2006 as applicable to companies subject to the small companies regime.

The financial statements are presented in pounds sterling which is the functional currency of the Company and rounded to the nearest £.

Going concern

On 30th June 2025 the entire share capital of the Company’s parent company Spex Group Holdings was purchased by Halliburton Global Holdings Limited “Halliburton”.

Since the date of acquisition, Halliburton have provided funding to the business and they have confirmed their willingness to continue to provide ongoing financial support to the group and its subsidiaries for at least the next 12 months from the date of approval of these financial statements.

In relation to ongoing litigation previously disclosed, the Scottish Court case has exhausted the appeals process by the third party and is considered closed, with awards to the Spex Group Companies. The Directors do not believe any liability to the Spex Group Companies remains pertaining to this matter.

With regards to the ongoing US Civil Case alleging the breach of a license agreement, the US Federal District Court has lifted the stay and allowed a 5th amended complaint to be filled by the Plaintiff. The Defendants have filed a Motion to Dismiss and the parties await the Court’s ruling on the motion. The Company has not made a provision in the accounts for any related liability, as it does not believe any liability exists.

At the time of approving the financial statements, the Directors have reviewed trading and cashflow forecasts for the next 12 months through to December 2026 and are satisfied that the Company will have sufficient financial resources to continue in operational existence for the foreseeable future.

On this basis, the Directors consider it appropriate to prepare the financial statements on a going concern basis.

Foreign currency

Transactions in foreign currencies are recorded at the rate of exchange at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies at the Balance Sheet date are reported at the rates of exchange prevailing at that date.

Exchange differences are recognised in the Profit and Loss Account in the period in which they arise except for exchange differences arising on gains or losses on non-monetary items which are recognised in the Statement of Comprehensive Income.

Turnover

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

Employee benefits

Short term benefits
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 as an expense when the Company is demonstrably committed to terminate the employment of an employee or to provide termination benefits.

Defined contribution schemes
Payments to defined contribution retirement benefit schemes are charged as an expense as they fall due.

Taxation

Current tax
Current tax is provided at amounts expected to be paid (or recoverable) using the tax rates and laws that have been enacted or substantively enacted at the Balance Sheet date.

Intangible assets

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

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

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

Development costs are amortised over 5 years.

Development costs 5 years straight line
Trademarks, patents and licences 5 years straight line
Research and development

Research expenditure is written off as incurred. Identifiable expenditure is capitalised to the extent that the technical, commercial and financial feasibility can be demonstrated.

Tangible fixed assets

Tangible fixed assets are stated at cost or valuation, net of depreciation and any provision for impairment. Depreciation is provided on all tangible fixed assets, at rates calculated to write off the cost or valuation, less estimated residual value, of each asset on a straight-line or reducing balance basis over its expected useful life, as follows:

Plant and machinery 4 years straight line
Computer equipment 4 years straight line

Residual value represents the estimated amount which would currently be obtained from disposal of an asset, after deducting estimated costs of disposal, if the asset were already of the age and in the condition expected at the end of its useful life.

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.

Impairment of assets

Assets, other than those measured at fair value, are assessed for indicators of impairment at each Balance Sheet date. If there is objective evidence of impairment, an impairment loss is recognised in the Profit and Loss Account as described below.

Non-financial assets
At each balance sheet date, the company reviews its tangible and intangible 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). The recoverable amount of an asset is the higher of its fair value less costs to sell and its 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.

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. 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.

Cash and cash equivalents

Cash and cash equivalents are basic financial assets and include deposits held at call with banks with original maturities of three months or less.

Financial instruments

Financial assets and financial liabilities are recognised when the Company becomes a party to the contractual provisions of the instrument.

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.

Financial assets and liabilities are only offset in the Balance Sheet when, and only when there exists a legally enforceable right to set off the recognised amounts and the Company intends either to settle on a net basis, or to realise the asset and settle the liability simultaneously.

Basic financial assets
Basic financial assets, which include debtors and bank balances, are measured at transaction price including transaction costs.

Basic financial liabilities
Basic financial liabilities, including creditors and loans from fellow group companies that are classified as debt, are recognised at transaction price.

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.

Equity instruments
Equity instruments issued by the Company are recorded at the fair value of cash or other resources received or receivable, net of direct issue costs. If payment is deferred and the time value of money is material, the initial measurement is on a present value basis. Dividends payable on equity instruments are recognised as liabilities once they are no longer at the discretion of the Company.

Government grants

Government grants are recognised based on the accrual model and are measured at the fair value of the asset received or receivable. Grants relating to assets are recognised over the expected useful life of the asset. Where part of a grant relating to an asset is deferred, it is recognised as deferred income.

2. Critical accounting judgements and key sources of estimation uncertainty

In the application of the Company’s accounting policies, the directors are required to make judgements that have a significant impact on the amounts recognised. The following are the critical judgements that the directors have made in the process of applying the Company’s accounting policies and that have the most significant effect on the amounts recognised in the financial statements.

Recoverability of group receivables:
The company makes an assessment of the recoverable value of amounts due from fellow group undertakings. When assessing the recoverability of these amounts owed, management considers factors such as expected future trading performance of the group.

Carrying value of intangible assets:
The recoverable value of development costs is a judgement exercised by management, with reference to the underlying economic and feasibility of each development project.

Going concern:
The going concern assumption is a judgement exercised by management (see note 1.2).
