FTSE 100 movers: Rightmove rallies on results; IAG flies lower

(Sharecast News) - London's FTSE 100 was 0.3% higher at 10,881.46 in afternoon trade on Friday. Rightmove was the standout gainer on the index as it posted a 9% jump in full-year underlying operating profit and revenue, and announced a £90m share buyback.

Russ Mould, investment director at AJ Bell, said: "Rightmove regained its poise after a wobbly period and topped the FTSE 100 risers' list. A resilient set of earnings, a new share buyback programme, and plans to launch an app inside ChatGPT have helped to calm investors' nerves.

"Rightmove spooked the market last year with plans to spend on AI-related services, and now it is under pressure to justify this expenditure and say how it will fight off competition from generative AI platforms."

LSEG was also in the black, a day after it unveiled plans to return £3bn to shareholders alongside a rise in annual earnings.

Melrose Industries slumped even as the aerospace and defence firm reported a 21% increase in profits last year as global tensions and conflicts sparked a "significant" increase in military spending.

Flutter Entertainment was under pressure as the Paddy Power owner's fourth-quarter results fell short of expectations.

IAG flew lower. The BA and Iberia owner said it had delivered another "record" financial performance in 2025 and that it would be returning €1.5bn of excess capital in the next 12 months, but shares fell, with analysts pointing to potential disappointment around guidance.
