Key Takeaways
- • London's takeover premiums have surged to an average of 45 percent in 2026, with foreign buyers accounting for 86 percent of total deal value and US acquirers representing half of all overseas bids, reflecting widespread strategic interest in undervalued UK assets.
- • Private equity and strategic buyers have launched 154 bids for UK companies valued above £100m since 2023, erasing £165bn in stock market capitalization, while London has attracted only 11 major listings totaling £6bn in the same period—a stark imbalance exposing the market's structural weakness.
- • High-profile rejected and accepted offers illustrate the valuation disconnect: Segro rejected a £12.6bn Prologis bid as "opportunistically timed," while Intertek accepted a £10.6bn offer from Swedish firm EQT after rejecting three prior bids, and budget airline Easyjet agreed to a £5.7bn Apollo takeover at an 81 percent premium.
- • Fund managers attribute the acquisition wave to buyers exploiting a significant valuation gap between UK equities and global competitors, with strategic rather than opportunistic activity driving deal flow according to Morningstar's chief European equity analyst Michael Field.
Summary
London's equity market faces a critical inflection point as private equity firms and strategic buyers aggressively pursue UK-listed companies at elevated premiums, exploiting what investors increasingly view as a valuation chasm between British assets and their global peers. The average takeover premium across 22 publicly disclosed deals has reached 45 percent in 2026, according to AJ Bell, signaling sustained acquirer appetite despite elevated offer prices.
The composition of bidders reveals a pronounced foreign appetite for UK assets. Overseas buyers account for 86 percent of total deal value, with US acquirers representing approximately half of all cross-border approaches. This geographic concentration underscores the perception among international capital allocators that UK equities remain undervalued relative to comparable assets in developed markets, particularly in North America.
The structural deterioration of London's market has accelerated markedly since 2023. According to Peel Hunt data, 154 acquisition bids targeting UK companies with market values exceeding £100m have been launched over the past three years, resulting in £165bn of equity market capitalization being withdrawn from public markets. This erosion contrasts sharply with London's anaemic IPO activity: only 11 listings by companies exceeding £100m have been completed, bringing total capital raised to just £6bn—a ratio that underscores the market's struggle to attract new public company formation.
High-profile transactions exemplify the dynamic. Budget airline Easyjet, a FTSE 250 constituent, agreed in principle to a £5.7bn takeover bid from Apollo at an 81 percent premium, exemplifying the premiums required to move deals forward. Intertek's acceptance of a £10.6bn offer from Swedish firm EQT followed three prior rejections, while real estate company Segro explicitly rejected a £12.6bn Prologis bid as "opportunistically timed," suggesting boards are increasingly attuned to valuation arbitrage motivating foreign bids. Michael Field, chief European equity analyst at Morningstar, characterized the activity as "very strategic and very specific" rather than indiscriminate, indicating that acquirers are targeting particular businesses rather than opportunistically pursuing broad market dislocations, though the sustained premium levels and deal frequency suggest structural undervaluation remains the dominant driver.
