London Stock Exchange Group plc

Interim results for six months ended 30 June 2025

Strong growth and margin progression, AEPS +20%, significant shareholder returns. 2025 margin guidance improved, new £1 billion share buyback in H2

David Schwimmer, CEO said:

"We have continued our strong and consistent growth track record, with a good performance from our subscription businesses enhanced by our leading markets platforms, which drove upside from increased volatility in the period. At the same time, we have improved our margins strongly as we realise the benefits of our ongoing transformation and deliver attractive operating leverage.

"We have built a business which is strategically aligned to a number of powerful growth drivers: the long-term growth in demand for data to feed and drive the modern economy, including for AI models, the digitisation of financial markets and the increasing demands of regulatory, financial and reputational risk management. We continue to make significant investments in product innovation for our customers, to generate growth over the long term. The first half was marked by a consistent cadence of new product launches, which we expect to continue in H2.

"Our strong cash generation supports significant shareholder returns: after the £500 million buyback in H1, we intend to execute up to a further £1 billion in buybacks over the coming months and have raised the interim dividend 15%. We also continue to evaluate inorganic growth opportunities. Given the substantial improvement in profitability year-on-year, we are also upgrading our margin guidance for 2025 to +75-100 bps from +50-100 bps."

Constant currency variances are calculated on the basis of consistent FX rates applied across the current and prior year period (GBP:USD 1.278 GBP:EUR 1.181). Organic growth is calculated on a constant currency basis, adjusting the results to remove disposals from the entirety of the current and prior year periods, and by including acquisitions from the date of acquisition with a comparable adjustment to the prior year.  Within the financial information and tables presented, certain columns and rows may not add due to the use of rounded numbers for disclosure purposes.
