The directors present their annual report and financial statements for the year ended 31 December 2025.
The principal activity of the company and group continued to be that of the
Going concern
During 2024, the Group’s shareholders were informed of an intention to seek further investment and an allotment of new shares to facilitate the ongoing trade and growth of the business up to the point of the business being self-sufficient. The first element of this investment was secured via an Advance Subscription Agreement (ASA) in H2 2024, which converted into equity in Q1 2025. Further investment was secured in December 2025 and April 2026, with the balance expected to be completed within Q2 2026.
The directors who held office during the year and up to the date of signature of the financial statements were as follows:
Azets Audit Services were appointed as auditor to the group and in accordance with section 485 of the Companies Act 2006, a resolution proposing that they be re-appointed will be put at a General Meeting.
This report has been prepared in accordance with the provisions applicable to companies entitled to the small companies exemption.
As permitted by s408 Companies Act 2006, the company has not presented its own profit and loss account and related notes. The company’s loss for the year was £2,230,020 (2024 - £1,991,129 loss).
Rheon Labs Ltd is a private company limited by shares incorporated in England and Wales. The registered office is 1 Broughton Street, Battersea, London, England, SW8 3QJ.
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 GB pounds, which is the functional currency of the company. Monetary amounts in these financial statements are rounded to the nearest GB pound.
The financial statements have been prepared under the historical cost convention. The principal accounting policies adopted are set out below.
The consolidated group financial statements consist of the financial statements of the parent company Rheon Labs Ltd together with all entities controlled by the parent company (its subsidiaries) and the group’s share of its interests in joint ventures and associates.
All financial statements are made up to 31 December 2025. Where necessary, adjustments are made to the financial statements of subsidiaries to bring the accounting policies used into line with those used by other members of the group.
All intra-group transactions, balances and unrealised gains on transactions between group companies are eliminated on consolidation. Unrealised losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred.
Rheon Labs Inc and Rheon Labs Shenzhen Trading Co. Ltd have been included in the group financial statements using the purchase method of accounting. Accordingly, the group profit and loss account and statement of cash flows include the results and cash flows of Rheon Labs Inc and Rheon Labs Shenzhen Trading Co. Ltd from their acquisition and incorporation respectively.
The Group made a loss before tax of £2,742,001 (2024: loss of £2,264,401).
During 2024, the Group’s shareholders were informed of an intention to seek further investment and an allotment of new shares to facilitate the ongoing trade and growth of the business up to the point of the business being self-sufficient. The first element of this investment was secured via an Advance Subscription Agreement (ASA) in H2 2024, which converted into equity in Q1 2025. Further investment was secured in December 2025 and April 2026, with the balance expected to be completed within Q2 2026.
The investment is expected to facilitate the ongoing trade and growth of the business up to the point of the business being self sufficient. On this basis, the directors consider it appropriate to prepare the accounts on the going concern basis, which assumes that the Group will continue in operational existence for the foreseeable future. Notwithstanding the confidence of the Directors, the ability of the Group to secure additional funding represents a material uncertainty that may cast significant doubt on the Group’s ability to continue as a going concern and, therefore, to continue realising its assets and discharging its liabilities in the normal course of business. These financial statements do not contain any adjustment that would arise if the financial statements were not drawn up 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 trade discounts, settlement discounts and volume rebates.
Product Revenue
Revenue generated from the sale of products is recognised when all the below is satisfied:
the company has transferred the significant risks and rewards of ownership to the buyer (usually on dispatch of the goods);
the amount of turnover can be measured reliably;
it is probably 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.
Non product revenue
Non product revenue is recognised when the amount of turnover can be measured reliably and it is probable that the company will receive the consideration due under the transaction.
Research expenditure is written off against profits in the year in which it is incurred.
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 recognised in the profit and loss account.
Equity investments are measured at fair value through profit or loss, except for those equity investments that are not publicly traded and whose fair value cannot otherwise be measured reliably, which are recognised at cost less impairment until a reliable measure of fair value becomes available.
In the parent company financial statements, investments in subsidiaries, associates and jointly controlled entities are initially measured at cost and subsequently measured at cost less any accumulated impairment losses.
A subsidiary is an entity controlled by the group. 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 group 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.
The carrying amount of the investments accounted for using the equity method is tested for impairment as a single asset. Any goodwill included in the carrying amount of the investment is not tested separately for impairment.
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.
The group 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 group's balance sheet when the group becomes party to the contractual provisions of the instrument.
Financial assets and liabilities are offset and 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.
Other financial assets, including investments in equity instruments which are not subsidiaries, associates or joint ventures, are initially measured at fair value, which is normally the transaction price. Such assets are subsequently carried at fair value and the changes in fair value are recognised in profit or loss, except that investments in equity instruments that are not publicly traded and whose fair values cannot be measured reliably are measured at cost less impairment.
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 assets are impaired where there is objective evidence that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows have been affected. If an asset is impaired, the impairment loss is the difference between the carrying amount and the present value of the estimated cash flows discounted at the asset’s original effective interest rate. The impairment loss is recognised in profit or loss.
If there is a decrease in the impairment loss arising from an event occurring after the impairment was recognised, the impairment is reversed. The reversal is such that the current carrying amount does not exceed what the carrying amount would have been, had the impairment not previously been recognised. The impairment reversal is recognised in profit or loss.
Financial assets are derecognised only when the contractual rights to the cash flows from the asset expire or are settled, or when the group transfers the financial asset and substantially all the risks and rewards of ownership to another entity, or if some significant risks and rewards of ownership are retained but control of the asset has transferred to another party that is able to sell the asset in its entirety to an unrelated third party.
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 group 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.
Derivatives, including interest rate swaps and forward foreign exchange contracts, are not basic financial instruments. Derivatives are initially recognised at fair value on the date a derivative contract is entered into and are subsequently re-measured at their fair value. Changes in the fair value of derivatives are recognised in profit or loss in finance costs or finance income as appropriate, unless hedge accounting is applied and the hedge is a cash flow hedge.
Debt instruments that do not meet the conditions in FRS 102 paragraph 11.9 are subsequently measured at fair value through profit or loss. Debt instruments may be designated as being measured at fair value through profit or loss to eliminate or reduce an accounting mismatch or if the instruments are measured and their performance evaluated on a fair value basis in accordance with a documented risk management or investment strategy.
Financial liabilities are derecognised when the group's contractual obligations expire or are discharged or cancelled.
The component parts of compound instruments issued by the group are classified separately as financial liabilities and equity in accordance with the substance of the contractual arrangement. At the date of issue, the fair value of the liability component is estimated using the prevailing market interest rate for a similar non-convertible instrument. This amount is recorded as a liability on an amortised cost basis using the effective interest method until extinguished upon conversion or at the instrument's maturity date. The equity component is determined by deducting the amount of the liability component from the fair value of the compound instrument as a whole. This is recognised and included in equity net of income tax effects and is not subsequently remeasured.
Equity instruments issued by the group 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 group.
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 group’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.
The carrying amount of deferred tax assets is reviewed at each reporting end date and reduced to the extent that it is no longer probable that sufficient taxable profits will be available to allow all or part of the asset to be recovered. 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 if, and only if, there is 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.
Equity-settled share-based payments are measured at fair value at the date of grant by reference to the fair value of the equity instruments granted using the Black Scholes model. The fair value determined at the grant date is expensed on a straight-line basis over the vesting period, based on the estimate of shares that will eventually vest. A corresponding adjustment is made to equity.
The expense in relation to options over the parent company's shares granted to employees of a subsidiary is recognised by the company as a capital contribution.
When the terms and conditions of equity-settled share-based payments at the time they were granted are subsequently modified, the fair value of the share-based payment under the original terms and conditions and under the modified terms and conditions are both determined at the date of the modification. Any excess of the modified fair value over the original fair value is recognised over the remaining vesting period in addition to the grant date fair value of the original share-based payment. The share-based payment expense is not adjusted if the modified fair value is less than the original fair value.
Cancellations or settlements (including those resulting from employee redundancies) are treated as an acceleration of vesting and the amount that would have been recognised over the remaining vesting period is recognised immediately.
For equity-settled share-based payment transactions the Group, in accordance with IFRS 2 'Share-Based Payments' measures their value and the corresponding increase in equity, indirectly, by reference to the fair value of the equity instrument granted. The fair value of those equity instruments is measured at the grant date using the black-scholes method. The expense is apportioned over the vesting period of the financial instrument and is based on the number which is expected to vest and the fair value of those financial instruments at the date of the grant. If the equity instruments granted vest immediately, the expense is recognised in full.
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 leased 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.
In the application of the group’s accounting policies, the directors are 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 following judgements (apart from those involving estimates) have had the most significant effect on amounts recognised in the financial statements.
Provisions have been made for expected credit losses and product warranties. These provisions are estimates and the actual costs and timing of the future cash flows are dependent on future events. Any differences between expectations and the actual future liability will be accounted for in the period when such determination is made.
The group recognises share based payments during the period and these estimates require certain judgements and estimates to be made. The Directors' believe that they have made judgements that are further explained in the notes and which are in accordance with UK Generally Accepted Accounting Practice.
The average monthly number of persons (including directors) employed by the group and company during the year was:
The number of directors for whom retirement benefits are accruing under defined contribution schemes amounted to 3 (2024 - 3).
Details of the company's subsidiaries at 31 December 2025 are as follows:
Work in progress represents compounded RHEON material.
Net proceeds of £163,797 were received in the year ended 31 December 2023 from the issue of convertible loan notes with a conversion date of 30 September 2025. These proceeds have been split between the financial liability element and an equity component, representing the fair value of the embedded option to convert the financial liability into equity. The liability portion of £147,610 was determined based on the discounted cashflows and the balance of £16,187 recognised as the equity element. These have been converted to shares in the year.
Net proceeds of £1,883,637 were received during the year ended 31 December 2024 in relation to an Advance Subscription Agreement for ordinary shares in the company. This liability has been settled in the year via the issue of a variable number of those shares.
Net proceeds of £41,255 were received during the year ended 31 December 2025 in relation to an Advance Subscription Agreement fo ordinary shares in the company. These proceeds have been recognised as a current liability at 31 December 2025 as the liability was to be settled via the issue of a variable number of those shares.
The liability component is measured at amortised cost, and the difference between the carrying amount of the liability at the date of issue and the amount reported in the Balance Sheet represents the effective interest rate less interest paid to that date.
The effective rate of interest is 4.25%.
The equity component of the convertible loan notes has been credited to the equity reserve.
A defined contribution pension scheme is operated for all qualifying employees. The assets of the scheme are held separately from those of the group in an independently administered fund.
