One rejected approach, a threat of legal action from lenders and an administration. That’s what it took for BT to land TalkTalk this week.
In the end it bought the business and PlatformX debt-free, adding c.2.5m customers, and the CMA had an inquiry open within hours.
In this week’s editorial, we look at UK public M&A, where size is no longer a defence. Prologis’ £14.3bn bid for SEGRO is the largest deal since 2018, and SEGRO is the sixth FTSE 100 company to accept an offer this year. Yet bidders are aiming high without overpaying, with average premiums down to 36.93% from 51% in 2023.
In the Rumour Mill, Axis Capital has floated €3.20 a share for PTSB, above BAWAG’s agreed €2.97. Kenmare Resources shares jumped 29% after an approach from IRH.
The Deal Tracker features 38 transactions this week. Three stood out:
- Informa is buying Clarion Events from Blackstone for £2.24bn. That brings ICE Barcelona and DSEI into its portfolio while it lines up a separation of Taylor & Francis.
- Ithaca Energy is paying up to $1.11bn for Suncor’s Terra Nova and White Rose stakes offshore Canada.
- CareTrust REIT agreed a c.£1.1bn pipeline deal for 45 UK care homes from LNT.

Weekly summary | 09.10.2026
This week’s Deal Tracker captures 37 transactions. Business services was the busiest sector with seven deals, followed by energy and resources with five. The biggest ticket was the £6.7bn takeover of Boots by Canada’s Weston Family, alongside Fairfax Financial Holdings.
Healthcare brought the other large cheques. AstraZeneca completed its $2bn equity investment in Summit Therapeutics, and CareTrust REIT agreed a c.£1.1bn pipeline deal for 45 UK care homes from LNT. Nova Capital’s purchase of BMP Group and RB Medical and Welford’s acquisition of a Belper care home show how active the sector is in the mid-market too.
Technology deals were smaller but more frequent. Sage made two bolt-ons in France, buying AI studio WholeHelp and Moovin’Cloud’s cloud platform. Analysys Mason added Swedish AI consultancy Modulai, and Kortext bought StudyStash just a year after the platform launched.
In energy, Ithaca Energy is paying $860m plus up to $250m in contingent payments for Suncor’s Terra Nova and White Rose stakes offshore Canada. Actis added 244MW of battery storage in Poland. Not everything got over the line: Reabold’s offer for Union Jack Oil lapsed at 13.02% acceptances.
Finally, BT bought TalkTalk out of administration, adding c.2.5m customers. The CMA has already opened an inquiry, so this deal isn’t done with the regulators yet.
Size is no longer a takeover defence
For years, sheer size was the best defence a UK plc had. Big balance sheets put off bidders, as did big shareholder registers and big price tags. In 2026, that is no longer true.
The biggest names are now in play
Prologis’ £14.3bn offer for SEGRO is the largest Takeover Code deal since 2018, according to Gibson Dunn’s latest UK Public M&A: The Month in a Minute. SEGRO is also the sixth FTSE 100 company to accept an offer this year.
Bidders are not waiting to be invited, either. Harworth was the fifth hostile bid of 2026, more than in any full year of the last decade.
A summer surge

The pipeline backs this up:
- Eight firm offers in June and 9 in July, the busiest run since mid-2025
- July also brought seven possible offers, a sign of more approaches still to come
- August and early September were quieter, although September was only half over when the report was published
But nobody is overpaying
This is where it gets interesting. Bigger targets have not meant richer bids.

The average bid premium stands at 36.93% in 2026, down from a peak of 51% in 2023 and broadly flat on last year. Bidders are aiming higher but paying less to get there.
Why it matters
Two forces seem to be at work. UK valuations are still low enough that a modest premium can look generous to shareholders. Boards, meanwhile, know that a big market cap no longer guarantees independence and that hostile bids are now a realistic option.
For targets, being big is no longer a defence in itself. A credible standalone plan is what counts now. For bidders, the window is open, but discipline on price is clearly part of the playbook.
The question for Q4: will premiums climb as competition for large assets increases, or are lower premiums here to stay?
