Segro Rejects £12.6bn Prologis Takeover Approach as US Rival Bid Stalls for FTSE Warehouse Firm

Segro (LSE: SGRO) rejected a £12.6 billion all-share takeover approach from US logistics giant Prologis (NYSE: PLD) on June 23, 2026. The proposal submitted on June 16 offered 0.084 new Prologis shares per Segro share, valuing the FTSE 100 firm at 925p per share, a 24.6% premium to Segro’s closing price of 742p. Prologis went public with the rejected bid on June 24, appealing directly to Segro shareholders. The UK warehouse sector is now firmly in the global M&A spotlight.

The Bid Details and Why Segro Said No

Segro’s board “unequivocally” rejected the proposal on June 23, with Prologis now going public to convince shareholders to back the deal. If completed, Segro shareholders would have owned approximately 10.5% of the enlarged combined group. The 925p offer also matches Segro’s last reported EPRA net tangible assets per share at the end of 2025, giving the board grounds to call it undervalued.

Prologis’s Case for the Deal

Prologis cited a stronger balance sheet, with net debt to enterprise value of 22% compared with 37% for Segro, arguing the UK firm’s growth has been constrained by its capital structure. Prologis also argued that Segro has traded at an average discount to net tangible assets of 19% and 17% over the past two and three years, respectively, and claimed a combined group could better unlock Segro’s data centre development pipeline.

Market Context: London’s Takeover Wave

Segro’s rejection lands in the middle of an accelerating trend of overseas bids for UK-listed firms. easyJet on Monday rebuffed US fund Castlelake’s £4.74 billion approach, while Intertek last week agreed a £9.5 billion takeover by Swedish investor EQT. The combined value of firms now poised to leave Britain’s stock market has reached £43 billion in 2026 alone. Segro sits at the centre of this contested landscape.

What Happens Next for Segro

Under UK City takeover rules, Prologis has until 5 pm on July 22, 2026 to make a firm bid for Segro or walk away for at least six months. Prologis holds a $140.9 billion market capitalization as the world’s largest logistics real estate investment trust, giving it considerable financial firepower if it chooses to return with a revised or formal offer before that deadline

Segro’s Standalone Position and Valuation

Segro has delivered muted returns in recent years, impacted by significant yield expansion following the 2022 interest rate spike, though analysts note its data centre pipeline adds latent long-term value. Prologis’s net debt-to-enterprise ratio of 22% versus Segro’s 37% remains the sharpest financial contrast between the two. For now, Segro’s board has chosen independence, but July 22 sets the clock.

Conclusion

Segro’s rejection of Prologis’s £12.6bn approach is one of the most significant M&A moments in UK real estate in 2026. With a firm bid deadline of July 22, a 24.6% premium on the table, and Prologis appealing directly to shareholders, the story is far from over. All eyes are now on whether Segro’s board can independently justify the premium it believes the company deserves.
