PERIMETER SOLUTIONS LIMITED NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 SEPTEMBER 2025
1. | General information
The Company is a private company limited by share capital and incorporated in England and Wales (registered number (07723309) under the Companies Act. The address of the principal place of business is Apollo House, Orbital One, Dartford DA1 1QG. 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 Financial Reporting Standard 102, the Financial Reporting Standard applicable in the UK and the Republic of Ireland and the requirements and the Companies Act 2006. 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 following principal accounting policies have been applied:
| 2.2 | Exemption from preparing consolidated financial statements
The Company is a parent company that is also a subsidiary included in the consolidated financial statements of a larger group by a parent undertaking established under the law of any part of the United Kingdom and is therefore exempt from the requirement to prepare consolidated financial statements under section 400 of the Companies Act 2006.
| 2.3 | Going concern
Company law requires the directors to consider the appropriateness of the going concern basis when preparing the financial statements. After reviewing the Company forecasts and projections, the directors have a reasonable expectation that the Company have adequate resources to continue in operational existence for the foreseeable future. Key to this assumption is the ongoing support from the ultimate parent company, Cedrus Topco Limited. The Company therefore continues to adopt the going concern basis in preparing its financial statements. Page 4
PERIMETER SOLUTIONS LIMITED NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 SEPTEMBER 2025 2.Accounting policies (continued)
| 2.4 | Revenue
Revenue is recognised to the extent that it is probable that the economic benefits will flow to the Company and the revenue can be reliably measured. Revenue 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 revenue is recognised: Sale of goods Revenue 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 revenue 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 Revenue 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 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.
| 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 | Interest income
Interest income is recognised in profit or loss using the effective interest method.
| 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. Page 5
PERIMETER SOLUTIONS LIMITED NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 SEPTEMBER 2025 2.Accounting policies (continued)
| 2.8 | Pensions
Defined contribution pension plan The Company operates 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.
| 2.9 | 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. Deferred tax balances are recognised in respect of all timing differences that have originated but not reversed by the balance sheet date, except that: ∙The recognition of deferred tax assets is limited to the extent that it is probable that they will be recovered against the reversal of deferred tax liabilities or other future taxable profits; and ∙Any deferred tax balances are reversed if and when all conditions for retaining associated tax allowances have been met. Deferred tax balances are not recognised in respect of permanent differences except in respect of business combinations, when deferred tax is recognised on the differences between the fair values of assets acquired and the future tax deductions available for them and the differences between the fair values of liabilities acquired and the amount that will be assessed for tax. Deferred tax is determined using tax rates and laws that have been enacted or substantively enacted by the balance sheet date. Page 6
PERIMETER SOLUTIONS LIMITED NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 SEPTEMBER 2025 2.Accounting policies (continued)
| 2.10 | 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, on a reducing balance basis. Depreciation is provided on the following basis:
|  |  |  | Plant and machinery | - |  | 5/6 years straight line
|  |  |  | Motor vehicles | - |  | 25% reducing balance
|  |  |  | Fixtures and fittings | - |  | 15% reducing balance
|  |  |  | Computer equipment | - |  | 15% reducing balance/3 year straight line
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.
| 2.11 | Valuation of investments
Investments in subsidiaries are measured at cost less accumulated impairment.
| 2.12 | Stocks
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.
| 2.13 | 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.
| 2.14 | 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.
| 2.15 | 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. Page 7
PERIMETER SOLUTIONS LIMITED NOTES TO THE FINANCIAL STATEMENTS FOR THE YEAR ENDED 30 SEPTEMBER 2025 2.Accounting policies (continued)
| 2.16 | 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.
| 2.17 | Dividends
Equity dividends are recognised when they become legally payable. Interim equity dividends are recognised when paid. Final equity dividends are recognised when approved by the shareholders at an annual general meeting.
3. | Employees
| The average monthly number of employees, including directors, during the year was 21 (2024 - 19).
