Prologis Makes $16.6B Hostile Bid for UK's SEGRO After Rejection

Warehouse giant goes hostile after SEGRO board rejects £12.6bn approach

Prologis, the world's largest industrial REIT with a $140.9 billion market capitalisation, went public on June 24 with an unsolicited all-share proposal to acquire UK-listed SEGRO after the British warehouse landlord's board "unequivocally" rejected the offer just one day earlierprnewswire +1. The bid values SEGRO at approximately £12.6 billion — roughly $16.6 billion — or 925 pence per share, a 24.6 per cent premium to SEGRO's closing price of 742 pence on June 23ir +1. SEGRO shares surged nearly 19 per cent on the news, lifting a broad swath of UK real estate stocks in sympathyquoteddata +1.

Terms of the all-share proposal and board pushback

Under the structure Prologis proposed, each SEGRO shareholder would receive 0.084 new Prologis shares — an exchange ratio implying the 925p per share price based on a GBP/USD rate of 1.32ir. Following completion, SEGRO shareholders would hold roughly 10.5 per cent of the enlarged group's issued share capitalprnewswire. The SEGRO board unanimously rejected the approach on June 23, calling it "opportunistically timed" and arguing the offer sought to exploit "clear dislocation" between its share price and the underlying value of its assets and development pipelinedatacenterdynamics +1. With the rejection made public, Prologis is now appealing directly to SEGRO shareholders — urging them to pressure the board to engage before a UK Takeover Code deadline of July 22, 2026ir.

Data centres and balance-sheet strength drive the strategic case

Prologis framed the combination as the only realistic route to unlocking SEGRO's data centre ambitions. SEGRO has operated powered-shell facilities in Slough — west of London — for around two decades, counting Amazon, Equinix, CyrusOne, and Iron Mountain among its tenantsdatacenterdynamics. The company says its portfolio contains more than 2.5 gigawatts of further data centre potential across the UK and continental Europe, with 1.1GW available to pre-let by end of 2028datacenterdynamics. Prologis, which itself has 5.6GW of power committed or in advanced negotiations and is targeting up to 10GW over ten years, argued it has the balance-sheet capacity and capital access to fund that pipeline — pointing to its own net debt-to-enterprise value of 22 per cent versus SEGRO's 37 per centir +1.

Wider implications for UK deal-making and logistics consolidation

The bid is the latest in a series of US corporate approaches to FTSE-listed companies, reflecting trans-Atlantic M&A momentum as dollar strength and UK equity discounts attract overseas buyerswsj +1. For the logistics real estate sector, the move signals that AI-driven data centre demand is reshaping deal logic: warehouse scale is increasingly less important than power procurement and digital infrastructure pipelinesdatacenterdynamics. Prologis has also outperformed SEGRO on total shareholder return by 37 percentage points over three years and 39 percentage points over fiveir. Whether that track record is enough to sway SEGRO investors — and force the board back to the table — will become clear before the July 22 deadlineir +1.
