Further, in our opinion, the Management's review gives a fair review of the development in the Company's activities and financial matters, of the results for the year and of the Company's financial position. We recommend that the annual report be approved at the annual general meeting. </sob:StatementByExecutiveAndSupervisoryBoards>

The financial statements are prepared in accordance with the Danish Financial Statements Act. In our opinion, the financial statements give a true and fair view of the Company's assets, liabilities,  and  financial  position  on  31 December  2023  and  of  the  results  of  the Company's  operations  for  the  financial  year  1 January  –  31 December  2023  in accordance with the Danish Financial Statements Act. </arr:OpinionOnAuditedFinancialStatements>
   <arr:DescriptionOfQualificationsOfAuditedFinancialStatements contextRef="ctx-1" id="pp-value-12-1" xml:lang="en">We conducted our audit in accordance with International Standards on Auditing (ISAs) and the additional requirements applicable in Denmark. Our responsibilities under those standards and requirements are further described in the "Auditor's responsibilities for the audit of the financial statements" section of our report. We  are  independent  of  the  Company  in  accordance  with  the  International  Ethics Standards  Board  for  Accountants'  International  Code  of  Ethics  for  Professional Accountants  (IESBA  Code)  and  the  additional  ethical  requirements  applicable  in Denmark,  and  we  have  fulfilled  our  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 for our opinion. </arr:DescriptionOfQualificationsOfAuditedFinancialStatements>
   <arr:StatementOfExecutiveAndSupervisoryBoardsResponsibilityForFinancialStatements contextRef="ctx-1" id="pp-value-13-1" xml:lang="en">Management is responsible for the preparation of financial statements that give a true and  fair  view  in  accordance  with  the  Danish  Financial  Statements  Act  and  for  such internal control that 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 Company's  ability  to  continue  as  a  going  concern,  disclosing,  as  applicable,  matters related to going concern and using the going concern basis of accounting in preparing the financial statements unless Management either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so. </arr:StatementOfExecutiveAndSupervisoryBoardsResponsibilityForFinancialStatements>
   <arr:StatementOfAuditorsResponsibilityForAuditAndAuditPerformed contextRef="ctx-1" id="pp-value-14-1" xml:lang="en">Our objectives are to obtain reasonable assurance as to 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 in Denmark will always detect a material misstatement when it  exists. Misstatements may  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 financial statement users made 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  company  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 Company'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 Company'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 Company to cease to continue as a going concern. —  evaluate the overall presentation, structure and contents of the financial statements, including  the  disclosures,  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>
   <arr:StatementOnManagementsReviewAuditorsReportOnAuditedFinancialStatements contextRef="ctx-1" id="pp-value-22-1" xml:lang="en">Management is responsible for the Management's review. Our opinion on the financial statements does not cover the Management's review, and we do not express any form of assurance conclusion thereon. In connection with our audit of the financial statements, our responsibility is to read the Management's review and, in doing so, consider whether the Management's review is materially inconsistent with the financial statements, or our knowledge obtained during the audit, or otherwise appears to be materially misstated. Moreover, it is our responsibility to consider whether the Management's review provides the information required under the Danish Financial Statements Act. Based on the work we have performed, we conclude that the Management's review is in accordance with the financial statements and has been prepared in accordance with the requirements of  the Danish  Financial Statement Act. We  did not  identify any  material misstatement of the Management's review. </arr:StatementOnManagementsReviewAuditorsReportOnAuditedFinancialStatements>

   <fsa:DisclosureOfAccountingPolicies contextRef="ctx-1" id="pp-value-41-1" xml:lang="en">The  annual  report  of  Hearts  &amp;  Science  is  included  in  the  consolidated  financial statements of Omnicom Media Group A/S. Basis of recognition and measurement Income is recognised in the income statement as earned, including value adjustments of financial  assets  and  liabilities.  All  expenses,  including  amortisation,  depreciation  and impairment losses, are also recognised in the income statement. Assets  are recognised in the  balance  sheet when  it  is  probable that future economic benefits will flow to the Company and the value of the asset can be measured reliably. Liabilities are recognised in the balance sheet when it is probable that future economic benefits  will  flow  from  the  Company  and  the  value  of  the  liability  can  be  measured reliably. On  initial  recognition,  assets  and  liabilities  are  measured  at  cost.  On  subsequent recognition, assets and liabilities are measured as described below for each individual accounting item. On recognition and measurement, allowance is made  for predictable losses and risks which  occur  before  the  annual  report  is  presented  and  which  confirm  or  invalidate matters existing at the balance sheet date. Income statement  Revenue Revenue consists of media revenue and revenue regarding consultancy services. Media  invoicing  to  customers  is  recognised  in  the  income  statement  provided  that delivery and transfer of risk to the buyer has taken place before year end and that the income  can  be  reliably  measured  and  is  expected  to  be  received.  Media  revenue  is measured ex. VAT, tax charged and rebates in connection with the sale. We act as an agent and revenue is recognised as invoicing to customers less media expenses. In our business we incur third‐party costs on behalf of clients. Third‐party direct costs include, among others: purchased media,  studio production services,  including  artists and  other  freelance  labour,  market  research  and  third‐party  data  and  other  related expenditures. The inclusion of billings related to third‐party direct costs in revenue depends on whether we  act  as  a  principal  or  as  an  agent  in  the  client  arrangement.  In  our  businesses, including advertising, which also includes studio production efforts and media planning and buying services, we act as an agent and arrange, at the client’s direction, for third parties to perform certain services. In these cases, we do not control the goods or services prior to the transfer to the client. As a result, revenue is recorded net of these costs, equal to the amount retained for our fee or commission. Contract  work  in progress  is recognised  as  revenue  as the production  is  carried  out. Accordingly, revenue corresponds to the selling price of work performed during the year (the percentage of completion method). Revenue is recognised when total income and expenses and the stage of completion of the contract at the balance sheet date can be reliably calculated and when it is probable that the economic benefits, including payment, will flow to the Group. Other external costs Other external costs comprise expenses for sale, advertising, administration, premises, etc. Staff costs Staff costs comprise salaries and wages, including holiday allowance, pension and other social security costs, etc., to the Company’s employees excluding refunds from public authorities. Financial income and expenses Financial income and expenses are recognised in the income statement at the amounts regarding the financial year. Financial income and expenses comprise interest income and  expense,  realised  and  unrealised  gains  and  losses  on  securities,  payables  and transactions denominated in foreign currencies as well as surcharges and refunds under the on-account tax scheme, etc. Tax on profit for the year Tax for the year comprises current tax and changes in deferred tax for the year. The tax expense relating to the profit/loss for the year is recognised in the income statement, and the tax expense relating to amounts directly recognised in equity is recognised directly in equity. The Company is jointly taxed with the other Omnicom companies in Denmark. The tax effect of the joint taxation is allocated in proportion to the taxable income (full absorption). Balance sheet Property, plant and equipment Fixtures and fittings and tools and equipment are measured at cost less accumulated depreciation and impairment. Cost comprises the purchase price and any costs directly attributable to the acquisition until the date when the asset is available for use. Depreciation is  provided on  a straight-line basis over the expected useful lives of  the assets. The expected useful lives are as follows: Fixtures and fittings, tools and equipment3-5yearsLeasehold improvements  During the lease periodProperty, plant and equipment are written down to the recoverable amount if this is lower than the carrying amount. Impairment tests are conducted of individual assets or groups of assets when there is an indication that they may be impaired. Gains and losses on the disposal of property, plant and equipment are determined as the difference between the sales price less disposal costs and the carrying amount at the  date of  disposal.  The  gains or  losses  are  recognised in  the income statement  as other operating income or other operating costs, respectively. Receivables Receivables are measured at amortised cost. Write-down is made for bad debt losses. Contract work in progress Contract  work  in  progress  is  measured  at  the  selling  price  of  the  work  performed calculated on the basis of the stage of completion. The stage of completion is measured by the proportion that the contract expenses incurred to date bear to the estimated total contract expenses. Where it  is  probable  that total contract expenses will exceed total revenues from a contract, the expected loss is recognised as an expense in the income statement. When the selling price of a construction contract cannot be measured reliably, the selling price is measured at the lower of costs incurred and net realisable value. Contract  work  in  progress  is  recognised  in  the  balance  sheet  under  receivables  or payables, depending on the net amount of the selling price less progress billings and prepayments. Selling  costs  and  costs  incurred  in  securing  contracts  are  recognised  in  the  income statement when incurred. Prepayments, assets Prepayments comprise costs incurred concerning subsequent financial years. Corporation tax and deferred tax Current tax payable and receivable is recognised on the balance sheet as tax computed on the taxable income for the year, adjusted for tax on the taxable income of prior years and for tax paid on account. Deferred  tax  is  measured  using  the  balance  sheet  liability  method  on  all  temporary differences between the carrying amount and the tax base of assets and liabilities. Where alternative tax rules can be applied to determine the tax base, deferred tax is measured based on the planned use of the asset or settlement of the liability, respectively. Liabilities Financial liabilities are recognised at the date of borrowing at the net proceeds received less transaction costs paid. In subsequent periods, the financial liabilities are measured at amortised cost, corresponding to the capitalised value using the effective interest rate. Accordingly, the difference between the proceeds and the nominal value is recognised in the income statement over the term of the loan together interest expenses. Trade payables and amounts owed to group entities are recognised at cost. Deferred income recognised as liabilities include incoming payments regarding income in following years. Other liabilities are measured at net realisable value. Foreign currency translation On initial recognition, transactions denominated in foreign currencies are translated at the  exchange  rates  at  the  transaction  date.  Foreign  exchange  differences  arising between  the  exchange  rates  at  the  transaction  date  and  at  the  date  of  payment  are recognised in the income statement as financial income or financial expenses. Receivables and payables and other monetary items denominated in foreign currencies are translated at the exchange rates at the balance sheet date. The difference between the exchange rates at the balance sheet date and at the date at which the receivable or payable arose or was recognised in the latest financial statements is recognised in the income statement as financial income or financial expenses. </fsa:DisclosureOfAccountingPolicies>
