As permitted by section 408 of the 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 £19,868,842 (2024 - £11,181,807 loss).
Peptone Limited (“the company”) is a private limited company domiciled and incorporated in England. The registered office is Cromwell House, 68 West Gate, Mansfield, Nottinghamshire, NG18 1RR.
The group consists of Peptone Limited and all of its subsidiaries.
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 as applicable to companies subject to the small companies regime. 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 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, modified to include certain financial instruments at fair value. The principal accounting policies adopted are set out below.
The consolidated group financial statements consist of the financial statements of the parent company Peptone Limited 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.
Subsidiaries are consolidated in the group’s financial statements from the date that control commences until the date that control ceases.
Entities in which the group holds an interest and which are jointly controlled by the group and one or more other venturers under a contractual arrangement are treated as joint ventures. Entities other than subsidiary undertakings or joint ventures, in which the group has a participating interest and over whose operating and financial policies the group exercises a significant influence, are treated as associates.
Investments in joint ventures and associates are carried in the group balance sheet at cost plus post-acquisition changes in the group’s share of the net assets of the entity, less any impairment in value. The carrying values of investments in joint ventures and associates include acquired goodwill.
If the group’s share of losses in a joint venture or associate equals or exceeds its investment in the joint venture or associate, the group does not recognise further losses unless it has incurred obligations to do so or has made payments on behalf of the joint venture or associate.
Unrealised gains arising from transactions with joint ventures and associates are eliminated to the extent of the group’s interest in the entity.
The directors have considered the group’s cash flow forecasts for at least 12 months from the date of approval of these financial statements, including expected research and development expenditure, available cash resources, and funding available under the convertible loan note arrangements.
Further drawdowns of approximately £706k, £3.34m and £3.43m were received after the reporting date. Having assessed these forecasts and the availability of continued funding, the directors consider it appropriate to prepare the financial statements on the going concern basis.
Turnover comprises sales of goods or services provided to customers net of value added tax and other sales taxes, less an appropriate deduction for actual and expected returns and discounts. Turnover is recognised when performance obligations are satisfied and the control of goods or services is transferred to the buyer. Where the performance obligation is satisfied over time, revenue is recognised in accordance with its progress towards complete satisfaction of that performance obligation.
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.
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 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.
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.
Leases are classified as finance leases whenever the terms of the lease transfer substantially all the risks and rewards of ownership to the lessees. All other leases are classified as operating leases.
Assets held under finance leases are recognised as assets at the lower of the assets fair value at the date of inception and the present value of the minimum lease payments. The related liability is included in the balance sheet as a finance lease obligation. Lease payments are treated as consisting of capital and interest elements. The interest is charged to profit or loss so as to produce a constant periodic rate of interest on the remaining balance of the liability.
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.
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 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 average monthly number of persons (including directors) employed by the group and company during the year was:

The net proceeds received from the issue of the convertible loan notes 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 loan notes that are repayable by March 2027 have the following conversion rights:
Subject to at least $35,000,000 gross proceeds of equity financing being raised by March 2027, the outstanding loans automatically convert into such number of fully paid Conversion Shares at a price per share equal to 0.80 multiplied by the lowest issue price per Conversion Share.
If less than $35,000,000 gross proceeds of equity financing being raised by March 2027, loan holders have the option of converting the outstanding loans into such number of fully paid Conversion Shares at a price per share equal to 0.80 multiplied by the lowest issue price per Conversion Share.
If the loans have not been converted or repaid, the holders have the option of converting the outstanding loans into such number of fully paid Conversion Shares at a price per share equal to £147.02 per Conversion Share.
If the loans have not been converted or repaid by March 2027, at least three loan holders may request for the loans to be repaid in cash.
The loan notes that are repayable by December 2027 have the following conversion rights:
Subject to at least $25,000,000 gross proceeds of equity financing being raised by December 2027, the outstanding loans automatically convert into such number of fully paid Conversion Shares at a price per share ranging between 0.50 to 0.70 multiplied by the lowest issue price per Conversion Share.
If less than $25,000,000 gross proceeds of equity financing being raised by December 2027, loan holders have the option of converting the outstanding loans into such number of fully paid Conversion Shares at a price per share ranging between 0.50 to 0.70 multiplied by the lowest issue price per Conversion Share, subject to the approval of other lead investors.

Following default by Peptone Limited, loan holders may request for the loans to be repaid in cash, subject to approval of other lead investors.
If the loans have not been converted or repaid by December 2027, loan holders may request for the loans to be repaid in cash, subject to approval of other lead investors.
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 13.01 and 13.15% respectively.
The equity component of the convertible loan notes has been credited to the equity reserve.
