London Stock Exchange Group (LSEG) has announced plans to launch a £3bn share buyback scheme in 2026, after returning £2.1bn to shareholders through buybacks in 2025.

In its full-year results, the financial markets infrastructure provider recorded a 10.6% increase in earnings to £4.3bn, while its profit before tax jumped by 56% to just over £1.9bn.

Furthermore, its reported operating profit rose by 45.4% to £2.1bn.

Chief executive officer at LSEG, David Schwimmer, stated: "We have achieved another year of very strong financial performance, driving continued top line momentum through significant investment in our product right across the business, bold strategic choices and an enduring focus on partnership with our customers.

"Our unmatched combination of trusted data and infrastructure is translating into deep customer engagement: in Q4 alone, major financial institutions signed long-term contracts worth £1.9bn to access our leading data and workflow.

"With our LSEG Everywhere data strategy, we are positioning ourselves as the partner of choice for licensed, trusted data as the use of AI in decision-making scales - and we are seeing very positive signs of adoption. In Post Trade Solutions, we have aligned ourselves strategically with key customers through their investment in the business."

In its guidance for 2026, LSEG expects its organic constant currency growth in total income to be between 6.5% and 7.5%, while its earnings margin is set to jump by between 80 and 100 bps.

The group said it has "consistently met or exceeded" its medium-term guidance framework outlined in 2023, and therefore it has put in a new framework for between 2027 and 2029, reflecting its confidence in continued strong progress.

LSEG now expects mid-to-high digit organic constant currency growth in annual total income, with its earnings margin increasing by a cumulative 150 bps between 2027 and 2029.

Following the publication of its final 2025 results, shares in LSEG jumped by over 7%.

Senior equity analyst at Hargreaves Lansdown, Matt Britzman, said that while the firm has delivered profit and revenue in line with expectations, its positivity "sits firmly in the outlook rather than the rear-view mirror".

He concluded: "The 2026 revenue growth guide of 6.5–7.5% edges ahead of prior consensus and suggests modest upgrades are likely, reinforcing confidence in the durability of the growth profile. Under the bonnet, the message is one of continued operating leverage and disciplined execution, rather than any single blow out line item. In short, no fireworks in the numbers, but enough reassurance to keep the investment case on track."
