STRATEGIC REPORT
FOR THE YEAR ENDED 31 DECEMBER 2025

Introduction
 
The director presents their strategic report for the year ended 31 December 2025.

Principal activities and review of the business
 
Portman Square US Holdings Limited ("the Company") is a wholly-owned subsidiary of Dentsu International Limited (the "Group") and is part of the Group's global corporate operations. The principal activity of the Company is to hold investments and to facilitate financing for the Group and it will continue to be so for the foreseeable future.

Dentsu International Limited manages its operations on a divisional basis. For this reason, the Company's director   believes that further key performance indicators for the Company are not necessary or appropriate for an understanding of the development, performance or position of the business. The performance of the Group's media operations, which includes the Company, is discussed in the Group's Annual Report which does not form part of this Report.

Principal risks and uncertainties
 
The components of financial risk are interest rate risk, credit risk, liquidity risk and cash flow risk. Due to the nature of the Company's business and the assets and liabilities contained within the Company's balance sheet, the director considers interest rate risk to be applicable due to changes in US Federal rate which have a direct impact on the Company's profit. The other risks are not considered significant to the Company.


This report was approved by the board and signed on its behalf.

INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF PORTMAN SQUARE US HOLDINGS LIMITED

Opinion


We have audited the financial statements of Portman Square US Holdings Limited (the 'Company') for the year ended 31 December 2025, which comprise the Statement of comprehensive income, the Balance sheet, the Statement of changes in equity and the related notes, including a summary of significant accounting policiesThe financial reporting framework that has been applied in their preparation is applicable law and United Kingdom Accounting Standards, including Financial Reporting Standard 101 ‘Reduced Disclosure Framework’ (United Kingdom Generally Accepted Accounting Practice).


In our opinion the financial statements:


give a true and fair view of the state of the Company's affairs as at 31 December 2025 and of its result for the year then ended;
have been properly prepared in accordance with United Kingdom Generally Accepted Accounting Practice; and
have been prepared in accordance with the requirements of the Companies Act 2006.


Basis for opinion


We conducted our audit in accordance with International Standards on Auditing (UK) (ISAs (UK)) and applicable law. Our responsibilities under those standards 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 ethical requirements that are relevant to our audit of the financial statements in the United Kingdom, including the Financial Reporting Council's Ethical Standard and we have fulfilled our other ethical responsibilities in accordance with these requirements. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.


Conclusions relating to going concern


In auditing the financial statements, we have concluded that the director's use of the going concern basis of accounting in the preparation of the financial statements is appropriate.


Based on the work we have performed, we have not identified any material uncertainties relating to events or conditions that, individually or collectively, may cast significant doubt on the Company's ability to continue as a going concern for a period of at least twelve months from when the financial statements are authorised for issue.


Our responsibilities and the responsibilities of the director with respect to going concern are described in the relevant sections of this report.


Other information


The other information comprises the information included in the Annual Report other than the financial statements and our Auditor's report thereon. The director is responsible for the other information contained within the Annual ReportOur opinion on the financial statements does not cover the other information and, except to the extent otherwise explicitly stated in our report, we do not express any form of assurance conclusion thereon. Our responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the financial statements or our knowledge obtained in the course of the audit, or otherwise appears to be materially misstated. If we identify such material inconsistencies or apparent material misstatements, we are required to determine whether this gives rise to a material misstatement in the financial statements themselves. If, based on the work we have performed, we conclude that there is a material misstatement of this other information, we are required to report that fact.


We have nothing to report in this regard.

INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF PORTMAN SQUARE US HOLDINGS LIMITED (CONTINUED)

Opinion on other matters prescribed by the Companies Act 2006
 

In our opinion, based on the work undertaken in the course of the audit:


the information given in the Strategic report and the Director's report for the financial year for which the financial statements are prepared is consistent with the financial statements; and
the Strategic report and the Director's report have been prepared in accordance with applicable legal requirements.


Matters on which we are required to report by exception
 

In the light of the knowledge and understanding of the Company and its environment obtained in the course of the audit, we have not identified material misstatements in the Strategic report or the Director's report.


We have nothing to report in respect of the following matters in relation to which the Companies Act 2006 requires us to report to you if, in our opinion:


adequate accounting records have not been kept, or returns adequate for our audit have not been received from branches not visited by us; or
the financial statements are not in agreement with the accounting records and returns; or
certain disclosures of director's remuneration specified by law are not made; or
we have not received all the information and explanations we require for our audit.


Responsibilities of directors
 

As explained more fully in the Director's responsibilities statement set out on page 2, the director is responsible for the preparation of the financial statements and for being satisfied that they give a true and fair view, and for such internal control as the director 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, the director 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 unless the director either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

INDEPENDENT AUDITOR'S REPORT TO THE MEMBERS OF PORTMAN SQUARE US HOLDINGS LIMITED (CONTINUED)

Auditor's responsibilities for the audit of the financial statements
 

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 (UK) 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.


Irregularities, including fraud, are instances of non-compliance with laws and regulations. We design procedures in line with our responsibilities, outlined above, to detect material misstatements in respect of irregularities, including fraud. The extent to which our procedures are capable of detecting irregularities, including fraud is detailed below:

The Company is subject to laws and regulations that directly affect the financial statements including financial reporting legislation. We determined that the following laws and regulations were most significant including UK Companies Act, employment law, health and safety, pensions legislation and tax legislation.

We understood how the Company is complying withthose legal and regulatory frameworks by making inquiries to management and those responsible for legal and compliance procedures. We assessed the extent of compliance    with these legal and compliance procedures as part of our procedures on the related financial statement items.

The engagement partner assessed whether the engagement team collectively had the appropriate competence and capabilities to identify or recognize non-compliance with laws and regulations. The assessment did not identify any issues in this area.

We assessed the susceptibility of the Company’s financial statements to material misstatement, including how fraud might occur. We identified the risk of override of controls as the area where the financial statements were most susceptible to material misstatement due to fraud. Audit procedures performed by the engagement team included:

°Identifying and assessing the design effectiveness of controls management has in place to prevent and detect fraud;
°Understanding how those charged with governance considered and addressed the potential for override of  controls or other in appropriate influence over the financial reporting process;
°Challenging assumptions and judgments made by management in its significant accounting estimates; and
°Identifying and testing journal entries, in particular any journal entries posted with unusual account combinations.

As a result of the above procedures, we considered the opportunities and incentives that may exist within the
organisation for fraud and identified the greatest potential for fraud in the following areas:

°The application of inappropriate judgements or estimation to manipulate the Company’s financial position;
°Posting of unusual journals and complex transactions; and
°The use of management override of controls to manipulate results, or to cause the Company to enter into transactions not in its best interests.

Because of the inherent limitations of an audit, there is a risk that we will not detect all irregularities, including those leading to a material misstatement in the financial statements or non-compliance with regulation. This risk increases the more that compliance with a law or regulation is removed from the events and transactions reflected in the financial statements, as we will be less likely to become aware of instances of non-compliance. The risk is also greater regarding irregularities occurring due to fraud rather than error, as fraud involves intentional concealment, forgery, collusion, omission or misrepresentation.


A further description of our responsibilities for the audit of the financial statements is located on the Financial Reporting Council's website at: www.frc.org.uk/auditorsresponsibilities. This description forms part of our Auditor's report.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2025

General information

Portman Square US Holdings Limited (the “Company”) is a private company incorporated, domiciled and registered in England in the UK. The registered number is 05996404 and the registered address is 10 Triton Street, Regent's Place, London, NW1 3BF. 

The financial statements of Portman Square US Holdings Limited (the “Company”) for the year ended 31 December 2025 were prepared in accordance with Financial Reporting Standard 101 ‘Reduced Disclosure Framework’ (FRS 101), Companies Act 2006 and applicable accounting standards. The financial statements are prepared under the historical cost convention, modified to include the revaluation of financial instruments.

The Company has taken advantage of the exemption under s400 of the Companies Act 2006 not to prepare group accounts as it is a wholly owned subsidiary of Dentsu Group Inc., a company incorporated under the laws of Japan. The results of Portman Square US Holdings Limited are included in the consolidated financial statements of    Dentsu Group Inc. which can be obtained from: The Secretary, Dentsu Group Inc., 1-8-1 Higashi-shimbashi,   Minato-ku, Tokyo 105-7050.

The financial statements are prepared in US Dollars (USD) and are rounded to the nearest thousand dollars (USD ‘000). The majority of the Company’s business is conducted in US Dollars and accordingly this is considered the Company’s functional currency.

2.Accounting policies

 
2.1

Basis of preparation

The Company has taken advantage of the following disclosure exemptions under FRS 101:
the requirements of paragraphs 62, B64(d), B64(e), B64(g), B64(h), B64(j) to B64(m), B64(n)(ii), B64(o)(ii), B64(p), B64(q)(ii), B66 and B67 of IFRS 3 Business Combinations;

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2025

2.Accounting policies (continued)

 
2.2

Going concern

The Company’s business activities, together with factors likely to affect its future development, performance and financial position and commentary on the Company’s financial results, its liquidity requirements and borrowing facilities are set out in the Strategic Report and in the accompanying Financial Statements.

In determining whether it is appropriate to continue to adopt the going concern basis in preparing the financial statements for 2025, the Board has considered the following factors:

The Company’s balance sheet position;
The maturity profile of the Company’s borrowings, its plans for refinancing and the Company’s access to credit facilities; and
Funding and support provided by the Company’s parent company.

Notwithstanding net current liabilities of $nil as at 31 December 2025 and with no profit or loss reported for the year, the financial statements have been prepared on a going concern basis which the Board considers to be appropriate. This is because the Company relies on Dentsu International Limited to provide such financial support as is required to meet its day to day financing requirements either directly or indirectly. The Director has considered the ability of Dentsu International Limited to provide such financial support as might be  required by the Company and accordingly has prepared the financial statements on a going concern basis.
 
As with any company placing reliance on other Group entities for financial support, the Board acknowledges that there can be no certainty that this support will continue although, at the date of approval of these financial statements, they have no reason to believe that this support will not continue.

Consequently, the Board is confident that the Company will have sufficient funds to continue to meet its liabilities as they fall due for at least 12 months from the date of approval of the financial statements and therefore have prepared the financial statements on a going concern basis.

  
2.3

Foreign currencies

The Company’s functional currency and presentation currency is US Dollars. Transactions in foreign  currencies are initially recorded in the functional currency by applying the spot exchange rate ruling at the date of the transaction. Monetary assets and liabilities denominated in foreign currencies are retranslated at the functional currency rate of exchange ruling at the balance sheet date. All differences are taken to the profit and loss for the financial year. Non-monetary items that are measured in terms of historical cost in a foreign currency are not retranslated.

  
2.4

Income taxes

Current tax is provided at amounts expected to be paid (or recovered) using the tax rates and laws that have been enacted or substantively enacted by the balance sheet date.

 
2.5

Investments

Investments in associates and subsidiary undertakings are stated at cost, less  impairment losses.

Investments are assessed at each reporting date to determine whether there is objective evidence that they  are impaired. An investment is impaired if objective evidence indicates that a loss event has occurred after the initial recognition of the investment, and that the loss event had a negative effect on the expected future cash flows of the investment. An impairment loss is calculated as the difference between its carrying amount and  the discounted value of the expected future cash flows.

NOTES TO THE FINANCIAL STATEMENTS
FOR THE YEAR ENDED 31 DECEMBER 2025

2.Accounting policies (continued)

  
2.6

Interest receivable and interest payable

Interest payable and similar expenses include interest payable and net foreign exchange losses that are recognised in the profit and loss account (see foreign currency accounting policy).

Interest income and interest payable is recognised in profit or loss as it accrues, using the effective interest method. Foreign currency gains and losses are reported on a net basis.

  
2.7

Financial instruments

(i) Recognition and initial measurement

Trade receivables are initially recognised when they are originated. All other financial assets and financial liabilities are initially recognised when the company becomes a party to the contractual provisions of the instrument.

A financial asset (unless it is a trade receivable without a significant financing component) or financial liability  is initially measured at fair value plus, for an item not at fair value through profit or loss (FVPL), transaction costs that are directly attributable to its acquisition or issue. A trade receivable without a significant financing component is initially measured at the transaction price.

(ii) Financial assets

Classification and measurement of financial assets

Management determines the classification and subsequent measurement of the financial asset based on the contractual terms at the initial recognition date and is not subsequently reclassified unless the Company changes its business model for managing financial assets. The classifications and subsequent measurement include the following:

Classification as trade receivables

Trade receivables are amounts due from customers for goods sold or services performed in the ordinary course of business. Trade receivables are initially recognised at fair value and subsequently measured at amortised cost using the effective interest method. Current trade receivables do not carry any interest charge. Interest may be charged on overdue balances.

Financial assets at amortised cost

The Company classifies its financial assets as measured at amortised cost only if both of the following criteria are met:

the asset is held within a business model whose objective is to collect the contractual cash flows, and
the contractual terms give rise to cash flows that are solely payments of principal and interest.

FOR THE YEAR ENDED 31 DECEMBER 2025

2.Accounting policies (continued)

2.7 Financial instruments (continued)

(ii) Financial assets (continued)

All receivables are categorised as amortised cost. The amortised cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognised in profit or loss. Any gain or loss on derecognition is recognised in profit or loss.

Financial assets at fair value through other comprehensive income

Financial assets at fair value through other comprehensive income (FVOCI) are initially measured at fair value, and subsequently measured at fair value with movements in fair value recorded in other comprehensive income. FVOCI comprise:

Equity securities which are not held for trading, and which the Company has irrevocably elected at initial recognition to recognise in this category. These are strategic investments and the group considers this classification to be more relevant. Dividends are recognised as income in profit or loss unless the dividend clearly represents a recovery of part of the cost of the investment. Other net gains and losses are being recognised in OCI and are never reclassified to profit and loss.

Debt securities where the contractual cash flows are solely principal and interest on specified dates, and the objective of the group’s business model is achieved both by collecting contractual cash flows and selling financial assets. Interest income calculated using the effective interest method, foreign exchange gains and losses and impairment are recognised in profit or loss. Other net gains and losses are recognised in OCI. On derecognition, gains and losses accumulated in OCI are reclassified to profit or loss.

Financial assets at fair value through profit or loss

The Company classifies the following financial assets and derivative financial assets at fair value through profit or loss (FVPL):

debt investments that do not qualify for measurement at either amortised cost or FVOCI
equity investments that are held for trading, and
equity investments for which the entity has not elected to recognise fair value gains and losses through OCI.

Financial assets carried at FVPL are initially recorded at fair value. Net gains and losses, including any interest or dividend income, are recognised in profit or loss.

Impairment of financial assets

The Company considers evidence of impairment for these assets at both an individual asset and a collective level at each reporting date. All individually significant assets are individually assessed for impairment. Those found not to be impaired are then collectively assessed for any impairment that has been incurred but not yet individually identified.

The Company applies the simplified approach to measuring expected credit losses which uses a lifetime expected loss allowance for all trade and other receivables. The Company uses the simplified provision matrix approach to calculate its expected credit losses taking into account various factors including the ageing of receivables, the credit rating of customers, market risk and any relevant credit enhancements.

(ii) Financial assets (continued)

Offsetting of balances within financial assets

If the Company has a legally enforceable right, and there is an intention to settle on a net basis, through signed legal agreements, to offset cash deposits and overdrafts that are in cash-pool arrangements with relationship banks. The Company does not offset other financial assets and liabilities where there is no legally enforceable right to do so.

(iii) Financial liabilities and equity

Classification and measurement

Management determines the classification of its financial liabilities as either debt or equity at initial recognition according to the substance of the contractual arrangements entered into. All financial liabilities are measured subsequently at amortised cost using the effective interest method or at FVPL. The classifications include the following:

Financial liabilities at fair value through profit or loss

Financial liabilities at fair value through profit or loss (FVPL) are either designated in this category; or they are held for trading, such as an obligation for securities borrowed in a short sale which are required to be returned in the future. Derivatives are also categorised as ‘held for trading’ unless they are designated as hedges. Subsequent to initial recognition, financial liabilities at fair value through profit or loss measured at fair value and net gains and losses, including any interest expense, are recognised in profit or loss.

Other financial liabilities measured at amortised cost using the effective interest method

Other financial liabilities measured at amortised cost using the effective interest method are non-derivative financial liabilities which are not designated on initial recognition as liabilities at fair value through profit or loss. Any subsequent interest expense and foreign exchange gains and losses are recognised in profit or loss. Any gain or loss on derecognition is also recognised in profit or loss.

Equity instruments

An equity instrument is any contract that evidences a residual interest in the assets of an entity after deducting all of its liabilities. Ordinary shares are classified as equity instruments. Equity instruments issued by the Company are recorded at the value of proceeds received, net of direct issue costs.

Intra-group financial instruments

Where the Company enters into financial guarantee contracts to guarantee the indebtedness of other companies within its group, the Company considers these to be insurance arrangements and accounts for  them as such. In this respect, the Company treats the guarantee contract as a contingent liability until such  time as it becomes probable that the Company will be required to make a payment under the guarantee.
