 summary of significant accounting policies. The financial statements are prepared in

​​In our opinion, the financial statements give a true and fair view of the Entity’s financial position at31.12.2025and of the results of its operations for the financial year 01.01.2025 - 31.12.2025  in accordance

​Accountants’ International Code of Ethics for Professional Accountants (IESBA Code) and the additional ethical 
​requirements applicable in Denmark, and we have fulfilled our other ethical responsibilities in accordance with 
​these requirements and the IESBA Code. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis

 with the Danish Financial Statements Act, and for such internal control as Management determines
​is necessary to enable the preparation of financial statements that are free from material misstatement,
​whether due to fraud or error.​​In preparing the financial statements, Management is responsible for assessing the Entity’s ability to continue
​as a going concern, for disclosing, as applicable, matters related to going concern, and for using the going
​concern basis of accounting in preparing the financial statements unless Management either intends to liquidate
​the Entity or to cease operations, or has no realistic alternative but to do so.</arr:StatementOfExecutiveAndSupervisoryBoardsResponsibilityForFinancialStatements>
   <arr:StatementOfAuditorsResponsibilityForAuditAndAuditPerformed contextRef="ctx-1" id="id-999gnxydhi8-1" xml:lang="en">Our objectives are to obtain reasonable assurance about whether the financial statements as a whole are
​free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes
​our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted
​in accordance with ISAs and the additional requirements applicable in Denmark will always detect a material
​misstatement when it exists. Misstatements can arise from fraud or error and are considered material if,
​individually or in the aggregate, they could reasonably be expected to influence the economic decisions of
​users taken on the basis of these financial statements.​​As part of an audit conducted in accordance with ISAs and the additional requirements applicable in Denmark,
​we exercise professional judgement and maintain professional scepticism throughout the audit. We also:Identify and assess the risks of material misstatement of the financial statements, whether due to
​fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence
​that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a
​material misstatement resulting from fraud is higher than for one resulting from error, as fraud may
​involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.​Obtain an understanding of internal control relevant to the audit in order to design audit procedures
​that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the
​effectiveness of the Entity’s internal control.​Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates
​and related disclosures made by Management.
​Conclude on the appropriateness of Management’s use of the going concern basis of accounting in
​preparing the financial statements, and, based on the audit evidence obtained, whether a material
​uncertainty exists related to events or conditions that may cast significant doubt on the Entity’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to
​draw attention in our auditor’s report to the related disclosures in the financial statements or, if such
​disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence
​obtained up to the date of our auditor’s report. However, future events or conditions may cause the
​Entity to cease to continue as a going concern.​Evaluate the overall presentation, structure and content of the financial statements, including the disclosures
​in the notes, and whether the financial statements represent the underlying transactions and
​events in a manner that gives a true and fair view.We communicate with those charged with governance regarding, among other matters, the planned scope
​and timing of the audit and significant audit findings, including any significant deficiencies in internal control
​that we identify during our audit.</arr:StatementOfAuditorsResponsibilityForAuditAndAuditPerformed>

 misstated.
​​Moreover, it is our responsibility to consider whether the management commentary provides the information
