Profit
Underlying growth in adjusted operating profit was 16%, with growth in each of Risk, STM and Legal in line with or ahead of revenue growth, and the improvement in profitability in Exhibitions reflecting the increased activity levels and a lower cost structure.
Acquisitions and disposals combined had a small negative impact on adjusted operating profit growth, giving growth at constant currency of 15%. Currency effects increased adjusted operating profit by 5%. Total adjusted operating profit, including the impact of acquisitions and disposals and currency effects, was £1,486m (2022: £1,239m).
The overall adjusted operating margin was 33.0% (2022: 31.2%). On an underlying basis, including cycling effects, the margin improved by 2.1 percentage points with portfolio changes reducing margin by 0.3 percentage points and currency being neutral on margin.
Reported operating profit was £1,308m (2022: £1,081m) up 21%, primarily reflecting the increase in adjusted operating profit.
Adjusted net interest expense was £136m (2022: £76m), with the increase reflecting higher average interest rates and currency translation effects.
Adjusted profit before tax was £1,350m (2022: £1,163m), up 16%. Reported profit before tax was £1,137m (2022: £998m) up 14%, reflecting the improvement in reported operating profit, the higher interest expense and an impairment charge for some assets held for sale.
The amortisation charge in respect of acquired intangible assets, including the share of amortisation in joint ventures, was £143m (2022: £143m).
Acquisition-related costs were £28m (2022: £14m), higher than the prior period due to timing of integration activity.
The adjusted tax charge was £284m (2022: £255m). The adjusted effective tax rate was 21.0% (2022: 21.9%), benefitting from non-recurring tax credits arising from the resolution of certain historical tax matters.
The adjusted tax charge excludes movements in deferred taxation assets and liabilities related to goodwill and acquired intangible assets but includes the benefit of tax amortisation where available on those items. Adjusted operating profits and taxation are grossed up for the equity share of taxes in joint ventures.
The application of tax law and practice is subject to some uncertainty and amounts are provided in respect of this. Discussions with tax authorities relating to cross-border transactions and other matters are ongoing. Although the outcome of open items cannot be predicted, no significant impact on profitability is expected.
The reported tax charge was £264m (2022: £238m), including tax associated with the amortisation of acquired intangible assets, disposals and other non-operating items.
