BASIS OF PREPARATION AND SIGNIFICANT ACCOUNTING POLICIES |
Exchange rates | Exchange rates The Group operates in many countries and earns revenues and incurs costs in many currencies. The results of the Group, as reported in Sterling, are affected by movements in exchange rates between Sterling and other currencies. Average exchange rates prevailing during the period, as modified by specific transaction rates for large transactions, are used to translate the results and cash flows of overseas subsidiaries into Sterling. Period-end rates are used to translate the net assets of those entities. The principal currencies and relevant exchange rates in the key markets where the Group operates are shown below. ​
​ | ​ | ​ | ​ | ​
​ | Average rates | Period-end rates
​ | Six months ended 30 June 2026 | Six months ended 30 June 2025 | As at 30 June 2026 | As at 30 June 2025
US$/£ | 1.34 | 1.30 | 1.32 | 1.37
Euro/£ | 1.15 | 1.19 | 1.16 | 1.17
CNY/£ | 9.24 | 9.42 | 8.98 | 9.82
​ In addition, the Group is exposed to currency fluctuations across a broad-based global footprint of emerging markets which, when combined, represent a significant part of the Group’s revenue.
Accounting for Argentina and Turkey as Hyperinflationary economies | Accounting for Argentina and Turkey as hyperinflationary economies ​ The Argentinian and Turkish economies are designated as hyperinflationary for accounting purposes. The Group has monitored the impact of inflation on its subsidiaries in these countries and does not believe that inflation had a material impact on the group over the past years. As a result, application of IAS 29 ‘Financial Reporting in Hyperinflationary Economies’ has been applied to Haleon entities whose functional currency is the Argentinian Peso or Turkish Lira effective 1 January 2024. ​ The application of IAS 29 includes:
• | Adjusting historical cost non-monetary assets and liabilities for the change in purchasing power caused by inflation from the date of initial recognition to the balance sheet date.
● | Adjusting the income statement for inflation during the reporting period.
● | Translating the income statement at the period end foreign exchange rate instead of an average rate.
● | Adjusting the income statement to reflect the impact of inflation and exchange rate movement on holding monetary assets and liabilities in local currency.
​ The main effects of applying IAS 29 on the Group’s condensed consolidated interim financial statements are:
● | Revenue and operating profit, for the period increased by £7 m and £2 m respectively;
● | A net monetary gain arising from hyperinflationary economies of £3 m was recorded in the income statement reflecting the impact on non-monetary assets and liabilities of hyperinflation from 1 January 2026 to 30 June 2026.
Going concern | Going concern The Directors have reviewed the Group’s cash flow forecasts, financial position and exposure to principal risks and have formed the view that the Group will generate sufficient cash to meet its ongoing requirements for at least 12 months from the date the condensed consolidated interim financial statements have been authorised. At 30 June 2026, the Group had cash and cash equivalents, net of bank overdrafts, of £805m and undrawn credit facility of £1,750m with maturity dates of August 2029. In addition, the Group has commercial paper programmes (with maximum aggregate amounts of €2bn and $10bn) pursuant to which members of the Group may issue commercial paper from time to time. As a result, the Directors believe that it is appropriate to adopt the going concern basis of accounting in preparing the Group’s condensed consolidated interim financial statements.
Judgements and estimates | Judgements and estimates In preparing the condensed consolidated interim financial statements, management is required to make judgements about when or how items should be recognised in the condensed consolidated interim financial statements and estimates and assumptions that affect the amounts of assets and liabilities, income and expenses reported in the condensed consolidated interim financial statements. Actual amounts and results could differ from these estimates. The critical areas of accounting estimates and judgements are the same as those disclosed in the published Group consolidated financial statements and related notes as at and for the year ended 31 December 2025.
Recent accounting developments | Recent accounting developments IFRS 18 ‘Presentation and Disclosure in Financial Statements’ will replace IAS 1 ‘ Presentation of Financial Statements’ and applies for annual and interim reporting periods beginning on or after 1 January 2027. As described in the Annual Report and Form 20-F 2025, the Group continues to assess the impact of IFRS 18, with initial system and process changes underway, while further work to finalise the financial statement presentation and disclosure is ongoing. All new accounting standards, amendments to accounting standards and interpretations that have been published by the IASB and are not effective for 30 June 2026 reporting period, have not been early adopted by the Group. Other than IFRS 18, these standards, amendments or interpretations are not expected to have a material impact on the entity in the current or future reporting periods.
