   <fsa:DisclosureOfAccountingPolicies contextRef="ctx-1" id="pp-value-20-1" xml:lang="en">As a result of the de-merger transaction carried out in 2023, de-merged activities are treated as discontinued operations and presented in a separate line item in the income statement.The Annual Report is presented in DKK 1,000.Intra-group business combinationsThe book value method is applied to de-mergers in which entities controlled by the parent company are involved, without any restatement of comparative figures. Differences between the agreed consideration and the carrying amount of the divested net assets, adjusted for tax on patents and know-how are recognised directly in equity.Translation of foreign currenciesOn initial recognition, transactions in foreign currencies are translated at the exchange rate at the transaction date. Receivables and payables and other monetary items in foreign currencies are translated at the exchange rate at the balance sheet date. All exchange rate adjustments are recognised in the income statement.Public grantsPublic grants to cover expenses are recognised in discontinued operations as other operating income when it is deemed likely that all grant criteria have been met. Grants which must be repaid under certain circumstances are recognised only where they are not expected to be repaid.Income StatementAdministrative costsAdministrative costs comprise costs incurred in the year for the administration of the company, e.g. audit fees and other administrative costs.Other operating incomeOther operating income comprise items of a secondary nature relative to the company's core activities, including gains of the sale of intangible assets.Financial income and expeses Financial income and expenses include interest income and expenses, e.g. from affiliated companies, bank charges, and fair value adjustments of conversion/repayment options. Financial income and expenses are recognised by the amounts pertaining to the financial year.TaxTax for the year includes current tax on the year's expected taxable income and the year's deferred tax adjustments. The portion of the tax for the year that relates to the profit/loss for the year is recognised in the income statement, whereas the portion that relates to transactions taken to equity is recognised in equity.Tax payable/receivable includes tax payable computed on the basis of the expected taxable income for the year and any adjustments of taxes payable for previous years and tax paid on account.The company is jointly taxed with the Danish companies in the Novo Holdings A/S Group. The tax effect of the joint taxation with the parent company and other subsidiaries is allocated to the companies in proportion to their taxable incomes (full allocation). The current tax in the joint taxation is paid by the ultimate parent company, Novo Holdings A/S, which functions as the tax administration company. The jointly taxed Danish enterprises have adopted the on-account taxation scheme.Discontinued operationsDiscontinued operations comprise the activities disposed of upon the de-merger that was executed in 2023. The profit/loss from discontinued operations after tax is presented in a separate line item in the income statement. Other operating income, expenses, financial expenses, and tax relating to discontinued operations are disclosed in the notes. Balance SheetAmounts owed by affiliated companiesAmounts owed by affiliated companies are stated at amortised cost less write-downs for potential losses on doubtful debts. Any write-downs are based on an individual assessment of each debtor.Other receivablesOther receivables are stated at amortised cost less write-downs for potential losses on doubtful debts. Any write-downs are based on an individual assessment of each debtor.Cash at bankCash at bank is valued at nominal value.EquityPurchase and sale of treasury shares are taken directly to equity under retained earnings.Proposed dividends (not yet declared) for the accounting period are recognised in the equity as proposed dividends.Capital contributions received from a parent company are recognised under retained earnings in equity.Other liabilitiesOther liabilities are measured at amortised cost.Convertible loansConvertible debt are initially separated into a debt component and a conversion option. The debt component is measured at amortized cost and the conversion option is measured at fair value through profit or loss.On initial recognition, the difference between the fair value of the liability component and the total proceeds is allocated to the conversion option. The conversion option is classified as a derivative liability, as it is not convertible into a fixed number of shares for a fixed amount of cash. Subsequent to initial recognition, the conversion option is accounted for as a derivative and thus, it is measured at fair value through profit or loss. Any gains or losses on the conversion option is recognized as part of financial items. The transaction costs are allocated to each component of the loan.Fair valueThe fair value measurement is based on the principal market. If no principal market exists, the measurement is based on the most advantageous market, i.e. the market that maximises the price of the asset or liability less transaction and/or transport costs.All assets and liabilities which are measured at fair value, or whose fair value is disclosed, are classified based on the fair value hierarchy, Level 1: Value in an active market for similar assets/liabilitiesLevel 2: Value based on recognised valuation methods on the basis of observable market informationLevel 3: Value based on recognised valuation methods and reasonable estimates (non-observable market information).If a reliable fair value cannot be stated according to the above levels, the asset or liability is measured at cost.</fsa:DisclosureOfAccountingPolicies>

   <fsa:DisclosureOfContingentLiabilities contextRef="ctx-1" id="pp-value-29-1" xml:lang="en">8 - ContingenciesThe company is jointly taxed with the Danish companies in the Novo Holdings A/S Group. The joint taxation also covers withholding taxes in the form of dividend tax, royalty tax and interest tax. The Danish companies are jointly and individually liable for the joint taxation. Any subsequent adjustments to income taxes and withholding taxes may lead to a larger liability. The tax for the individual companies is allocated in full on the basis of the expected taxable income.As a consequence of the de-merger of the company in 2023, the company has a contingent liability for any obligation that existed at the time of the de-merger, in the event that a creditor of a capital company that participated in the de-merger is not fully satisfied. Hence, the company may be jointly and severally liable up to the maximum amount of the net assets value contributed or remaining at the time of the de-merger. At the date of these financial statements, there are no known liabilities relating to the de-merger that could impact the company in the future.</fsa:DisclosureOfContingentLiabilities>
