FTSE 100 movers: LSEG surges on acquisition, guidance upgrade; miners slump

(Sharecast News) - London's FTSE 100 was flat at 10,751.42 in afternoon trade on Thursday. London Stock Exchange Group surged as it announced the acquisition of credit specialist Octus from Permira for $3.5bn, and lifted its full-year guidance.

LSEG said the acquisition will transform its presence in credit and private market data, "creating a leading proposition in these high-growth areas".

Rentokil Initial rallied after a third-quarter update. Russ Mould, investment director at AJ Bell, said: "Signs Rentokil is starting to root out some of the bugs which have infested its North American business helped drive a major relief rally in the shares.

"After a major profit warning and the abandonment of profit margin targets for its business across the Atlantic earlier this year, investors welcomed signs of stabilisation in this business and news of a sizeable share buyback.

"The buyback is a show of confidence on the part of management. Despite today's upwards move, the shares are still down 20% so far in 2026 and investors will be looking for management to build on this improvement rather than resting on their laurels."

Precious metals miner Fresnillo lost its shine as gold prices fell, while miners Anglo American, Antofagasta, Rio Tinto and Glencore all declined in tandem with copper prices.
