After a quiet spring, UK deal-makers roared back this week as buyers targeted everything from 5G networks to precision instruments. Five transactions worth a combined £24 billion show overseas strategics and private-equity giants still view London-listed companies as bargains.
Telecoms led the headlines with the formal birth of VodafoneThree, while rival bidders tussled for healthcare landlord Assura. Further down the market-cap scale, engineering names Spectris and Ricardo attracted international interest, and Qualcomm opened its chequebook for fast-growing chip IP group Alphawave.
Together, the deals underline the twin dynamics of sterling weakness and sector-specific growth stories that continue to pull global capital into the UK.
VodafoneThree is born
The long-trailed £16.5 billion merger officially closed on 31 May, but the newly branded VodafoneThree laid out its first post-deal roadmap this week. The combined operator now counts 27 million mobile customers and has pledged to invest £11 billion over the next decade to blanket 99 percent of the country with 5G. While some of the duo’s 640 high-street stores will consolidate, the JV says it will add about 400 UK-based customer-service roles and 9,000 network-build jobs annually during peak rollout years. Analysts see the tie-up as a scale play that could pressure BT and Virgin Media O2 if integration costs stay on track.
The Competition and Markets Authority cleared the deal in May, subject to a series of commitments — including £11 billion of network investment over the next decade. VodafoneThree will operate independently of its parent companies, with a remit to accelerate 5G rollout and improve service coverage nationally. The merger is expected to reshape the competitive dynamics of the UK mobile market.

Qualcomm buys Alphawave for $2.4 bn
San Diego-based Qualcomm agreed to pay $2.4 billion for London-listed Alphawave, a designer of high-speed chip-connect IP essential to AI data-centre processors. The offer — 96 percent above Alphawave’s pre-rumour price — allows shareholders to choose cash, Qualcomm stock or exchangeable notes, letting founders roll over equity.
At more than 50× forecast 2025 EBITDA the valuation looks rich, but Qualcomm is betting the technology will help it diversify away from smartphones as Apple internalises more silicon. UK officials welcomed the deal as evidence of the country’s strength in semiconductor design, though another flagship listing will disappear.
Spectris warms to Advent’s £3.73bn approach

British precision-measurement specialist Spectris surprised the market this week by agreeing in principle to a £3.73 billion ($5.06 billion) cash proposal from US buy-out house Advent at 37.63 pence per share — an 85 percent premium that sent the shares up 70 percent. The board had rebuffed earlier overtures, but protracted US-China tariff woes and a sluggish order book evidently tipped sentiment.
Advent now has until 7 July to go firm; if it does, Spectris would become the largest UK industrial to exit the LSE this year, feeding the narrative that London’s valuations are too cheap to ignore.
KKR / Stonepeak lift bid for Assura to £1.7 bn
The week’s fiercest bidding war played out in primary-care real estate. Private-equity duo KKR and Stonepeak raised their “best and final” cash offer for Assura to 52.1 pence per share, valuing the NHS-focused landlord at almost £1.7 billion and eclipsing a rival cash-and-stock pitch from Primary Health Properties. Assura’s board now backs the PE consortium, calling the bid lower-risk and free of disposals.
At a 39 percent premium to Assura’s undisturbed price, the move highlights how international funds are hunting stable, inflation-linked UK assets amid volatile global rates.
WSP Global picks up Ricardo for £363 m
Canada’s WSP Global continued its UK shopping spree, agreeing on Wednesday to acquire 104-year-old engineering and environmental consultancy Ricardo for 430 pence a share—about £363 million including debt, a 28 percent premium. Activist investor Science Group, which held 22 percent, immediately agreed to sell most of its stake. For WSP the deal bolsters expertise in sustainable transport and clean-energy advisory, complementing 2023’s swoop on RPS Group. For Ricardo it ends months of strategic uncertainty and delivers shareholders a cash exit at a price last seen in early 2023.
This week’s deals offer a sharp snapshot of where global buyers see lasting UK value. The VodafoneThree creation may grab the attention, but it’s the sheer breadth of transactions — spanning telecoms, chip design, healthcare property, and precision engineering — that marks a decisive shift in sentiment.
Crucially, foreign capital is again leading the charge: US, Canadian and European buyers accounted for every major acquisition, reinforcing the idea that UK assets remain attractive not despite recent economic uncertainty, but because of it.
The return of big premiums, particularly in the Spectris and Alphawave deals, also suggests buyers are willing to pay for strategic fit and IP-rich capabilities. Meanwhile, the Assura bidding war signals renewed appetite for dependable income-linked assets in a high-rate world. Taken together, this week points to a more selective but increasingly assertive M&A environment that is driven less by opportunism and more by long-term alignment, technical value, and international confidence in the UK’s listed market.
