The scale of the departure from the London Stock Exchange was laid bare on the first trading day back from the summer break, as three listed companies simultaneously unveiled plans to exit the market.

FTSE 250 members Bodycote and Gamma Communications, together with energy firm Capricorn, each announced fresh offers to be taken private, with a combined takeover value exceeding £3bn. All three deals would see long-standing London constituents absorbed by private equity firms or overseas-listed rivals, the two categories of buyer behind most of the exodus this year.

Macclesfield-based Bodycote, the largest of the three and a constituent of the London Stock Exchange since 1972, said it had reached an agreement to be acquired by US private equity firm Veritas Capital in a deal valuing the company at £1.9bn. The offer of 932p per share represents a 41.4 per cent premium over the average price of 659.5p per share for the twelve months to May. The announcement follows the metallurgy business having rebuffed earlier approaches from Veritas and CVC. Bodycote provides thermal processing and testing services used across aerospace, automotive and energy supply chains, a stable, cash-generative industrial profile of the kind buyout firms have repeatedly targeted in the UK, where share valuations have traded at a persistent discount to US peers.

Fresh pressure on the London Stock Exchange

Gamma Communications has recommended a £1.1bn offer from UK private equity firm Epiris, just days after confirming it was in talks with European buyout firm Waterland over a possible takeover. Gamma supplies internet, phone and mobile services to UK small and medium-sized businesses.

Epiris said on Tuesday it had made an all-cash bid for the FTSE 250 telecoms provider, at a 53 per cent premium to its share price before takeover speculation first emerged several months ago.

Waterland, an Irish-based dealmaking firm, had planned to gatecrash the sale of Gamma to Epiris before offloading much of the business to Giacom, a telecoms firm chaired by Matthew Riley. Its interest had raised the prospect of another bidding war for a London Stock Exchange firm, just weeks after Apollo saw off fierce competition from US buyout firm Castlelake to complete its acquisition.

Epiris's formal offer, arriving just a day before a Takeover Panel deadline, is likely to end months of speculation over Gamma's future. The telecoms company first told shareholders it was in talks with Epiris in May, since when it has also seen off interest from Providence Equity Partners and Oakley Capital.

Separately, Capricorn Energy has signed an agreement with Norwegian rival DNO for $396m (£292m), a deal that will end Capricorn's 38-year stint on the London Stock Exchange. The Scottish energy firm switched its recommended offer from Genel Energy to DNO after the Scandinavian bidder tabled an offer $36m higher than Genel's. DNO already holds production assets across the North Sea and the wider region, and the combination would consolidate Capricorn's portfolio under an Oslo-listed operator.

This trio of takeovers will pile further pressure on the leadership of the London Stock Exchange, which has been losing constituents at a record pace this year. More than 50 companies have now either accepted offers or are subject to interest from firms that are either private or listed abroad. London-listed mainstays including Schroders, Beazley and Intertek have all quit the market in 2026, just as the bourse has struggled to attract fresh listings to replace them. The shrinkage matters beyond the exchange itself: fewer listed companies reduce the pool of UK equities available to British pension funds and retail investors, and chip away at the fee income and advisory work that underpin the City of London's position as a financial centre. Regulators and the government have responded with reforms aimed at making London more competitive, including overhauled listing rules designed to make the bourse more attractive to companies raising capital, though the measures have yet to stem the outflow.

"Any hope that the steady leak of FTSE companies to overseas buyers has stopped will have been dashed by this morning's trio of announcements," said Chris Beauchamp, chief market analyst at IG. "Barely a month after the deal to take Easyjet private, yet more firms are being bought up, with London remaining a bargain bucket worth investigating by others. While not of Easyjet's size or reputation, the news is another blow to the efforts of the London Stock Exchange, the City of London and the government to maintain the importance of London's financial markets."

What happens next rests on shareholder votes and, for the private buyers, the usual closing conditions: each deal requires approval by Gamma's, Bodycote's and Capricorn's investors before the delistings can proceed, while further approaches for London-listed firms cannot be ruled out in a market where more than 50 names are already in play.
