Connect 2 Cleanrooms Limited is a private company limited by shares incorporated in England and Wales. The registered office is Fifth Floor, 5 New Street Square, London, EC4A 3BF. The principal place of business is located at Riverside House, Forge Lane, Lancaster, LA2 6RH.

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, including the provisions of the Large and Medium- sized companies and Groups, (Accounts and Reports) Regulations 2008.

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 33 ‘Related Party Disclosures’: Compensation for key management personnel.

The company has taken advantage of the exemption under section 400 of the Companies Act 2006 not to prepare consolidated accounts. The financial statements present information about the company as an individual entity and not about its group.

Connect 2 Cleanrooms Limited is a wholly owned subsidiary of Angstrom Technology Limited and the results of Connect 2 Cleanrooms Limited are included in the consolidated financial statements of Angstrom Technology Limited which are available from Fifth Floor, 5 New Street Square, London, EC4A 3BF, and at Companies House.

The director hatrues concluded that it is appropriate to prepare the financial statements on a going concern basis as the company has adequate cash resources and financial projections indicate that the company will generate operating cashflows through its trade.

The director is taking all reasonable steps to efficiently manage cash flow, and to plan appropriate commercial actions to take during this period of instability across the UK economy. The company is reprioritising its strategies and the first step involved the closure of one business stream after the year end, as further disclosed within the ‘Post balance sheet events’ note to the financial statements. The company has received confirmation of ongoing financial support by a US based parent company and its fellow UK group members.

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

Turnover is recognised at the fair value of the 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. The fair value of consideration takes into account discounts.

Revenue from the sale of goods is recognised when the significant risks and rewards of ownership of the goods have passed to the buyer (usually on dispatch of the goods), the amount of revenue can be measured reliably, it is probable that the economic benefits associated with the transaction will flow to the entity and the costs incurred or to be incurred in respect of the transaction can be measured reliably.

Revenue from contracts to provide cleanrooms is recognised with reference to stage of completion of the contract activity at the reporting end date based on the percentage of costs incurred against total expected costs. When it is probable that total contract costs will exceed total contract turnover, the expected loss is recognised as an expense immediately. Where the outcome of a construction contract cannot be estimated reliably, contract revenue is recognised to the extend of contract costs incurred where it is probable that they will be recoverable.

Revenue from maintenance contracts is recognised on a straight line basis over the term of the contract. Any revenue received in advance is included in accruals and deferred income.

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.

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

Amortisation is recognised so as to write off the cost of assets less their residual values over their useful lives on the following bases:

Tangible fixed assets are initially measured at cost and subsequently measured at cost, net of depreciation.

Depreciation is recognised so as to write off the cost 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.

Interests in subsidiaries are initially measured at cost and subsequently measured at cost less any accumulated impairment losses. The investments are assessed for impairment at each reporting date and any impairment losses or reversals of impairment losses are recognised immediately in profit or loss.

A subsidiary is an entity controlled by the company. Control is the power to govern the financial and operating policies of the entity so as to obtain benefits from its activities.

At each reporting period end date, the company reviews the carrying amounts of 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). 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.

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.

Stocks are stated at the lower of standard cost and estimated selling price less costs to complete and sell.

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

Basic financial assets, which include trade and other debtors, amounts owed by group undertakings and cash and bank balances, are initially measured at transaction price including transaction costs.

All of the company's financial assets are basic financial instruments.

Financial assets, other than those held at fair value through profit and loss, are assessed for indicators of impairment at each reporting end date.

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 trade and other creditors and amounts due to group undertakings, are initially recognised at transaction price.

All of the company's financial liabilities are basic financial instruments.

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.

Deferred tax is calculated at the tax rates that are expected to apply in the period when the liability is settled or the asset is realised. Deferred tax is charged or credited in the profit and loss account, except when it relates to items charged or credited directly to equity, in which case the deferred tax is also dealt with in equity. Deferred tax assets and liabilities are offset when the company has a legally enforceable right to offset current tax assets and liabilities and the deferred tax assets and liabilities relate to taxes levied by the same tax authority.

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 leases asset are consumed.

Government grants are recognised at the fair value of the asset received or receivable when there is reasonable assurance that the grant conditions will be met and the grants will be received.

A grant that specifies performance conditions is recognised in income when the performance conditions are met. Where a grant does not specify performance conditions it is recognised in income when the proceeds are received or receivable. A grant received before the recognition criteria are satisfied is recognised as a liability.

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.

In the application of the company’s accounting policies, the director is required to make judgements, estimates and assumptions about the carrying amount of assets and liabilities that are not readily apparent from other sources. The estimates and associated assumptions are based on historical experience and other factors that are considered to be relevant. Actual results may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised where the revision affects only that period, or in the period of the revision and future periods where the revision affects both current and future periods.

The estimates and assumptions which have a significant risk of causing a material adjustment to the carrying amount of assets and liabilities are as follows.

In producing the financial statements. management have made estimates over the profitability of individual long term contracts. Costs are recognised as they are incurred and with contract income and therefore profits adjusted, based on the proportion of total projected contract costs incurred at the reporting date.

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

In addition to the above expenses, redundancy payments of £7,544 (2023: £71,750) were paid and are included in exceptional administrative costs.

Details of the company's subsidiaries at 31 December 2024 are as follows:

An impairment expense of £80,000 (2023: £19,000) was recognised in respect of stocks.

The company owes £1,930,000 to a fellow group company, which has confirmed it will not compel any repayments for a minimum of one year after the balance sheet date. The balance is also interest free.

Management have made certain assumptions surrounding a repayment profile and market cost of capital to compute the present value of this balance owed at the balance sheet date. In recognising the present value, a discount of £54,042 (2023: £126,349) was booked, with a consequential recognition of a non-distributable capital contribution reserve of the same amount, which is disclosed in the statement of changes in equity.

As the balance is repaid in future financial periods, this position will unwind to zero.

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

The deferred tax assets set out above are expected to be reversed within 12 months. The deferred tax liability set out above is expected to reverse over the life of the related assets.

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.

Included within other creditors are pension contributions outstanding totalling £9,692 (2023: £10,423).

On 14 January 2022, the company issued 35 'E' Ordinary shares of 10p each, with a nominal value of £3.50.

Following this, on 8 March 2022, all classes of shares were re-designated to 'Ordinary shares' and all share rights were aligned to have full voting, dividend and capital distribution rights.
