Key takeaways

  • UK-listed companies have faced a sustained wave of takeover approaches, with 2024 seeing a sharp jump in the value of recommended bids and overseas buyers dominating deal flow.
  • London-listed shares trade at a wide valuation discount to Wall Street, with the FTSE All Share on a far lower forward earnings multiple than US benchmarks.
  • Years of outflows from UK equity funds and a retreat by domestic pension schemes have thinned out the natural buyers who once supported London valuations.
  • Reforms are under way, including the FCA’s 2024 listing-rule overhaul and the 2025 Mansion House Accord on pension investment, but their effects will take years to show.
  • Foreign investment is not inherently negative, yet the loss of headquarters, listings and decision-making from the UK carries real economic and strategic questions.

Britain’s public companies have rarely been so easy to buy. From cyber-security groups to housebuilders, drinks makers to postal operators, a steady procession of London-listed businesses has changed hands or fielded approaches over the past two years, very often from overseas trade buyers or private equity houses. In July 2026, according to reporting in the Financial Times, the paper’s editorial board (the FT View) argued that the UK’s business case needs strengthening to arrest what risks becoming a self-reinforcing “great British corporate sell-off” and an exodus of London-listed companies into foreign hands.

That framing captures a debate that has been building for years. The question is not whether individual deals make sense; many do, and shareholders are frequently paid handsome premiums. The question is what it means for the country when its stock market shrinks, its most recognisable names disappear into private ownership or foreign parents, and the pool of new listings fails to replenish the losses. This article sets out the evidence behind the trend, why UK companies look cheap, who is buying, and how to weigh the opportunities against the risks. It is general information only and not financial advice.

The trend: a sustained wave of UK takeovers

The scale of the buying is best seen in the flow of firm, recommended offers. Analysis by AJ Bell found that UK takeover activity surged in 2024, with around £49 billion of recommended bids for London-listed companies, up sharply from £17.2 billion the year before. Five FTSE 100 constituents and 19 FTSE 250 companies received bids during the year, and the average deal value climbed to roughly £1.07 billion, close to three times the 2023 figure. Crucially, the majority of offers were all-cash, and the average bid premium was around 45%, which AJ Bell characterised as handing shareholders the equivalent of several years of UK stock-market returns upfront.

The roll-call of targets reads like a tour of corporate Britain. In the FTSE 100, the cyber-security group Darktrace was acquired by the US private equity firm Thoma Bravo, packaging giant DS Smith was absorbed into a transatlantic combination, and the investment platform Hargreaves Lansdown agreed a take-private led by a private equity consortium. Mining major Anglo American fended off an approach from Australia’s BHP, while the property portal Rightmove rebuffed repeated advances from Australia’s REA Group. Further down the market, Britvic was bought by Denmark’s Carlsberg, insurer Direct Line was acquired by Aviva in a domestic deal, and names such as Redrow, Wincanton, TI Fluid Systems, Virgin Money and Centamin all left the market through mergers or takeovers.

Behind the headline deals lies a broader tilt toward overseas acquirers. Market data compiled from adviser sources indicated that in the first half of 2024, around 72% of UK deal value involved overseas buyers, the highest such share in three years, with US-headquartered firms alone accounting for hundreds of UK acquisitions. The Office for National Statistics, which publishes quarterly figures on mergers and acquisitions involving UK companies, has tracked elevated inward activity through 2024 and 2025. The direction of travel is clear even as individual quarters wobble: the UK has become an unusually active market for inbound deals relative to its size, and foreign buyers have supplied a disproportionate share of the firepower.

The valuation gap: cheap by almost any measure

The single most important reason foreign buyers keep circling is price. UK equities have spent years trading at a discount to global peers, and the gap versus the United States in particular has become striking. According to data from LSEG published in mid-2025, the FTSE All Share traded on a forward price-to-earnings multiple of about 12.7 times, against roughly 22.5 times for the US Russell 1000 index (around 20.2 times even if the dominant “Magnificent Seven” technology stocks are stripped out). On that basis, American shares were changing hands at close to 1.74 times the UK’s earnings multiple.

Income tells a similar story. The same LSEG analysis put the UK dividend yield at around 3.3%, against roughly 1.2% for US equities. UK companies also return large sums through share buybacks, so the total yield on offer to a would-be acquirer is meaningful. For a strategic buyer able to fund a deal cheaply, or a private equity firm confident it can improve margins and eventually re-sell or re-list, a business generating steady cash flow at a low multiple is an obvious target. LSEG’s own relative-value scoring placed the FTSE 100 well above the Russell 1000 on measures designed to flag undervaluation against fundamentals, reinforcing the perception that London is where the bargains sit.

Currency has periodically sharpened the appeal. When sterling has been soft against the dollar, a UK company priced in pounds becomes cheaper still for a buyer earning in dollars, effectively layering a currency discount on top of the valuation discount. That dynamic was widely cited during earlier waves of US buying. The picture is not static, however: at times the pound has strengthened as the dollar weakened, which erodes part of that advantage. Currency is therefore a swing factor rather than the core driver, but at the margin it has helped tip deals over the line.

Why London is cheap: de-equitisation and the retreat of domestic buyers

Cheapness is not an accident of sentiment alone; it reflects a structural shift in who owns UK shares. Over two decades, domestic institutions have steadily reduced their exposure to their home market. LSEG data show that UK equities made up around 78% of a combined UK, US and global equity holding measure in 2004, but had fallen to roughly 27.3% by 2024. Fund-flow figures are equally stark: UK equity fund classifications saw cumulative outflows of nearly £102 billion over that period, with the bulk, more than £95 billion, withdrawn from 2021 onwards. Money that left the UK did not vanish; it largely flowed into global and US funds instead.

The pension system sits at the heart of this. British defined-benefit schemes, as they matured and de-risked, shifted heavily out of equities and into bonds, while many defined-contribution default funds allocate only a small slice to UK-listed shares. The result is a market with fewer committed domestic owners to bid up prices or defend companies against opportunistic offers. Analysts describe this process as “de-equitisation”: the shrinking of the listed equity base as takeovers, buybacks and delistings remove companies faster than new flotations replace them.

The listings side of the ledger has been weak for years. The UK Listing Review noted that the number of listed companies had fallen by around 40% from a 2008 peak, and that the UK accounted for only a small fraction of global IPO activity in the years to 2020. When a company is taken over and delisted, it is not being offset by a healthy pipeline of new arrivals; several high-profile firms have also chosen to move their primary listing abroad, most often to New York, in search of higher valuations and deeper capital pools. Each departure narrows the market a little further, which can depress valuations for those that remain and, in turn, make them more vulnerable to the next bid. That is precisely the self-reinforcing loop the FT View warned about.

The case that it matters

Does it matter if a British company ends up owned in Chicago, Copenhagen or by a buyout fund in London’s Mayfair? There are reasons to think it can.

First, listings and headquarters carry an ecosystem with them. A UK-listed company supports domestic advisers, auditors, brokers, lawyers and fund managers, and its presence in an index draws passive and active investment into the country. As the listed pool shrinks, that ecosystem thins, and the City’s role as a global capital-raising centre is gradually eroded.

Second, ownership can influence where decisions are made and where value accrues. Foreign parents may, over time, relocate senior functions, research and development, or profit centres closer to their own base. Private equity ownership can bring welcome investment and discipline, but also higher leverage and a focus on eventual exit rather than long-term stewardship. Neither outcome is inevitable, yet the loss of home-grown decision-making is a legitimate concern for a country that wants to retain strategic industries.

Third, there is a national-capability dimension. In sensitive sectors such as defence, critical infrastructure, advanced technology and life sciences, the ownership of key firms has security as well as economic implications. The UK’s National Security and Investment regime exists precisely to screen deals in these areas, a recognition that not all acquisitions are equal.

The counter-case: foreign investment can be a good thing

It would be a mistake to treat every takeover as a loss. Inward investment has long been a strength of the UK economy, and there are solid arguments on the other side.

Selling shareholders, including UK pension savers and retail investors, are frequently paid substantial premiums, often 30% to 50% above the pre-bid price. That is real value crystallised for domestic savers, and the cash can be recycled into other investments. A market that is “too cheap” is, from this angle, simply correcting: buyers are doing the work that reluctant domestic investors would not.

Foreign owners can also bring capital, expertise, access to larger markets and long-term commitment that a stretched public company might struggle to fund alone. Many overseas-owned businesses in Britain invest heavily, create jobs and expand. The UK’s openness to capital is part of what has made it an attractive place to do business, and a reflex against all foreign ownership would risk deterring the investment the economy needs. The honest position is that the quality and terms of a deal matter more than the nationality of the buyer.

Impact on investors, the economy and jobs

For investors, the takeover wave has been a double-edged sword. Holders of acquired companies have banked premiums, but they then face the problem of reinvesting in a shrinking market, often at the cost of losing exposure to a quality business they wanted to own for the long term. A run of bids can flatter short-term returns while quietly hollowing out the opportunity set. It has also drawn attention back to UK valuations, with some commentators arguing the discount itself is the opportunity; this article takes no view on any individual security.

For the wider economy, the effects are mixed and play out slowly. Deal activity generates fees and, where premiums are reinvested domestically, can support other businesses. But a persistently undervalued, shrinking equity market makes it harder and costlier for UK companies to raise growth capital at home, which matters for productivity and for scaling the next generation of firms.

On jobs, the evidence is genuinely case-by-case. Some acquisitions preserve and expand employment; others bring restructuring, cost-cutting and the loss of head-office roles. Private equity ownership in particular can go either way depending on the strategy and the debt load involved. Blanket claims in either direction should be treated with caution.

Opportunities, challenges and material risks

The opportunities are real. A cheap market with strong dividend yields and cash-generative companies is attractive to long-term buyers, and continued bid activity can act as a floor under valuations. Policy reform, if sustained, could gradually rebuild the domestic investor base and narrow the discount.

The challenges are equally clear. Reversing years of outflows and rebuilding a listings pipeline is a long game, and confidence is fragile. Global capital will keep gravitating to the highest-returning markets, and the US has been a powerful magnet.

Several material risks deserve emphasis. Valuation gaps can persist for far longer than expected, so “cheap” is not the same as “about to re-rate”. Takeover premiums, while attractive, remove companies permanently from the market. Higher interest rates raise the cost of the leverage that private equity relies on, which can slow deal flow. Currency swings can quickly change the maths for overseas buyers in either direction. And policy is uncertain: reforms may under-deliver, or well-intentioned rules could have unintended consequences. None of this constitutes a recommendation to buy or sell any investment.

What happens next

Policymakers are not standing still. In July 2024 the Financial Conduct Authority implemented the biggest overhaul of the UK listing rules in more than three decades, replacing the old two-tier structure with a single listing category and removing some of the mandatory shareholder votes and other frictions that had deterred companies from choosing London. The FCA framed the changes as accepting more risk in order to support growth; the regulator’s Sarah Pritchard said a thriving capital market was “vital in delivering investment to growing companies plus returns and choice to investors”. The reforms took effect on 29 July 2024, though their impact on new listings will take years to judge.

On the demand side, attention has turned to pensions. The Mansion House Accord, published on 13 May 2025, saw 17 of the UK’s largest workplace pension providers voluntarily commit to investing at least 10% of their main default funds in private markets by 2030, with half of that earmarked for UK assets, a step expected to channel around £50 billion toward domestic private and growth investments. It significantly expands the earlier 2023 Mansion House Compact, which set a 5% target with no domestic requirement. Ministers have signalled they will monitor progress and have reserved powers to compel allocations if voluntary efforts fall short. The accord is weighted toward private markets rather than listed shares, but it is part of a wider push to get more British capital working in British companies.

The open questions are whether these measures, together with the introduction of intermittent private-share trading venues such as PISCES and continued lobbying for higher UK equity allocations in defined-contribution defaults, can rebuild a self-sustaining domestic market. If they succeed, the valuation gap could narrow and the flow of takeovers ease as prices rise. If they do not, the FT View’s warning about a self-reinforcing sell-off will remain live. Either way, expect the debate over London’s competitiveness, and the steady drumbeat of bid speculation around undervalued FTSE names, to continue through 2026.

Conclusion

The “great British corporate sell-off” is not a single event but a slow-moving structural story. UK-listed companies look cheap relative to global peers, domestic investors have spent years pulling back, the listings pipeline has thinned, and into that vacuum have stepped foreign trade buyers and private equity firms willing to pay premiums for quality assets on the cheap. Some of that activity is healthy, crystallising value for savers and bringing in investment; some of it raises harder questions about where Britain’s biggest companies are owned, listed and run. Reforms to listing rules and pension allocation may, in time, rebuild the domestic foundations of the market. Until they do, the incentives that keep foreign buyers targeting UK companies will remain firmly in place.
