Prologis, Inc. disclosed on June 24 an unsolicited all-share proposal valuing UK REIT SEGRO plc at £12.6 billion, after SEGRO’s board rejected the approach on June 23. The UK Takeover Panel has set a deadline of July 22 for Prologis to announce a firm offer or withdraw.
Offer Terms and Strategic Rationale
Prologis sent an unsolicited all-share proposal to SEGRO’s board on June 16, offering 0.084 new Prologis shares for each SEGRO share. This exchange ratio implied a price of 925 pence per SEGRO share and would leave SEGRO shareholders with about 10.5% of Prologis’ enlarged share capital. The bidder based its valuation on Prologis’ closing price of $145.30 and a GBP:USD rate of 1.32 on June 23. The proposal represented a 24.6% premium to SEGRO’s closing price that day and larger premiums to its one-month and three-month volume-weighted averages. The implied price matched SEGRO’s last reported net tangible asset value (NTA) per share as of December 31, 2025.
Prologis framed the combination as a way to give SEGRO investors access to the world’s largest logistics real estate investment trust (REIT) and its global platform. It argued that its stronger balance sheet and diversified capital resources could unlock embedded value in SEGRO’s development and data-centre pipeline. Prologis cited its market capitalization at about $140.9 billion.
Rejection and Next Steps
SEGRO’s board unanimously rejected the proposal on June 23, calling it “opportunistically timed” and saying it “falls a long way short of SEGRO’s own views on value.” The board said the approach appeared aimed at exploiting a disconnect between the company’s share price and its underlying prospects.
Prologis is urging SEGRO shareholders to encourage the board to engage and said it would consider a binding offer if granted access. The company cautioned there is no certainty a formal bid will be made. Neither company adjusted previously issued earnings or dividend guidance. No firm offer, detailed term sheet, break fee, or minimum-acceptance condition has been announced, and no formal merger-control filings have been disclosed.
Under the UK Takeover Code, Prologis must announce a firm intention to make an offer or confirm it will not proceed by 5 p.m. BST on July 22, the “put up or shut up” deadline. Market observers note room for a higher bid given the gap between the implied price and the board’s valuation, but Prologis has not indicated plans to increase the exchange ratio or price.
“The proposal falls a long way short of SEGRO’s own views on value,” the SEGRO board said, describing the timing as opportunistic and aimed at exploiting the “clear dislocation between SEGRO’s current share price and its highly attractive underlying business and strong prospects.”[16]
