The company's registration number is 03069609.

The registered office is located at Millweye Court, 73 Southern Road, Thame, Oxfordshire, OX9 2ED.

2.Accounting policies

 
2.1

Basis of preparation of financial statements

The financial statements have been prepared under the historical cost convention unless otherwise specified within these accounting policies and in accordance with FRS 102 'The Financial Reporting Standard applicable in the UK and the Republic of Ireland' and the requirements of the Companies Act 2006.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 MARCH 2025

2.Accounting policies (continued)

 
2.3

Foreign currency translation

Functional and presentation currency

The Company's functional and presentational currency is GBP.

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 except when deferred in other comprehensive income as qualifying cash flow hedges.

Foreign exchange gains and losses that relate to borrowings and cash and cash equivalents are presented in the Statement of Income and Retained Earnings within 'finance income or costs'. All other foreign exchange gains and losses are presented in profit or loss within 'other operating income'.

FOR THE YEAR ENDED 31 MARCH 2025

2.Accounting policies (continued)

 
2.4

Revenue

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. The following criteria must also be met before turnover is recognised:

Sale of goods

Turnover from the sale of goods is recognised when all of the following conditions are satisfied:
the Company has transferred the significant risks and rewards of ownership to the buyer;
the Company retains neither continuing managerial involvement to the degree usually associated with ownership nor effective control over the goods sold;
the amount of turnover can be measured reliably;
it is probable that the Company will receive the consideration due under the transaction; and
the costs incurred or to be incurred in respect of the transaction can be measured reliably.

Rendering of services

Turnover from a contract to provide services is 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 turnover 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.

 
2.5

Operating leases: the Company as lessee

Rentals paid under operating leases are charged to profit or loss on a straight-line basis over the lease term.

 
2.6

Research and development

In the research phase of an internal project it is not possible to demonstrate that the project will generate future economic benefits and hence all expenditure on research shall be recognised as an expense when it is incurred. Intangible assets are recognised from the development phase of a project if and only if certain specific criteria are met in order to demonstrate the asset will generate probable future economic benefits and that its cost can be reliably measured. 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.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 MARCH 2025

2.Accounting policies (continued)

 
2.7

Finance costs

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. Issue costs are initially recognised as a reduction in the proceeds of the associated capital instrument.

 
2.8

Borrowing costs

All borrowing costs are recognised in profit or loss in the year in which they are incurred.

 
2.9

Pensions

Defined contribution pension plan

The Company contributes into 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 plan are held separately from the Company in independently administered funds.

 
2.10

Current and deferred taxation

The tax expense for the year comprises current and deferred tax. Tax is recognised in profit or loss 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.

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.


 
2.11

Intangible assets

Intangible assets are initially recognised at cost. After recognition, under the cost model, intangible assets are measured at cost less any accumulated amortisation and any accumulated impairment losses.

All intangible assets are considered to have a finite useful life. If a reliable estimate of the useful life cannot be made, the useful life shall not exceed ten years.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 MARCH 2025

2.Accounting policies (continued)

 
2.12

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:

Motor vehicles
-
25%
Fixtures and fittings
-
25%
Computer equipment
-
25%
Other fixed assets
-
50%

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.

 
2.13

Impairment of fixed assets and goodwill

Assets that are subject to depreciation or amortisation are assessed at each balance sheet date to determine whether there is any indication that the assets are impaired. Where there is any indication that an asset may be impaired, the carrying value of the asset (or cash-generating unit to which the asset has been allocated) is tested for impairment. An impairment loss is recognised for the amount by which the asset's carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset's (or CGU's) fair value less costs to sell and value in use. For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (CGUs). Non-financial assets that have been previously impaired are reviewed at each balance sheet date to assess whether there is any indication that the impairment losses recognised in prior periods may no longer exist or may have decreased.

 
2.14

Valuation of investments

Investments in subsidiaries are measured at cost less accumulated impairment.

 
2.15

Stocks and work in progress

Stocks are stated at the lower of cost and net realisable value, being the estimated selling price less costs to complete and sell. Cost is based on the cost of purchase on a first in, first out basis. Work in progress and finished goods include labour and attributable overheads.

At each balance sheet date, stocks are assessed for impairment. If stock is impaired, the carrying amount is reduced to its selling price less costs to complete and sell. The impairment loss is recognised immediately in profit or loss.

FOR THE YEAR ENDED 31 MARCH 2025

2.Accounting policies (continued)

 
2.16

Debtors

Short-term debtors are measured at transaction price, less any impairment. 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.

 
2.17

Cash and cash equivalents

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.

 
2.18

Creditors

Short-term creditors are measured at the transaction price. Other financial liabilities, including bank loans, are measured initially at fair value, net of transaction costs, and are measured subsequently at amortised cost using the effective interest method.

 
2.19

Provisions for liabilities

Provisions are recognised when an event has taken place that gives rise to a legal or constructive obligation, a transfer of economic benefits is probable and a reliable estimate can be made.

Provisions are measured as the best estimate of the amount required to settle the obligation, taking into account the related risks and uncertainties.
 
Increases in provisions are generally charged as an expense to profit or loss.

Details of security provided:

During the year ended 31 March 2019, the company issued £3,300,000 convertible loan notes that were repayable on 31 March 2021; these have since been rolled over for a further 12 months and repayments will commence in the 31 March 2025 financial year. Interest is charged on the notes at 6%.

The convertible loan notes are non-basic financial instruments. The loan notes were initially and subsequently measured at fair value through profit and loss, using the Black Scholes model. Significant assumptions in the valuation included the share price, expected annual volatility and expected option life. Movements are recorded as finance income or expenses in the profit and loss. The difference between the fair value at grant date and the monies received represents a capital contribution by shareholders.

Share-based payments

In 2023 the company granted options under an approved EMI option plan 'The Wirth Resarch Limited EMI Share Option Scheme' (the agreement) These options were granted on 7 November 2022. All options granted have performance conditions relating to the relevant employee remaining an employee. The options can be exercised from the earlier of an exit event or 31 March 2025. 

The Black-Scholes option pricing model was used to value the share-based payment awards as it was considered  that  this  approach  would  result  in  materially  accurate  estimate  of  the  fair  value  options granted.

The table below sets out the number of options granted during the year and oustanding at the end of fthe year; and is reflective of the directors' best estimate of the number of options anticipated to be exercised in accordance with the terms and conditions of each share option agreement.
