Prologis Wins Segro Board Backing for £14 Billion 'Best and Final' Takeover

Timeline: From Initial Approach to the Takeover Panel Deadline

• June 16, 2026 — Prologis delivers an indicative all-share proposal to Segro's board at 0.084 new Prologis shares per Segro share, valuing Segro at roughly £12.6 billion ($16.6 billion), or 925 pence per share .
• June 23, 2026 — Segro's board "unanimously and unequivocally" rejects the initial proposal, calling it opportunistic and saying it "significantly undervalues" Segro .
• June 24, 2026 — Prologis takes its bid public, going directly to Segro's shareholders. The UK Takeover Panel imposes a "put up or shut up" (PUSU) deadline of July 22, 2026, by which Prologis must either announce a firm intention to make an offer or withdraw .
• July 16, 2026 — Prologis submits a third, sweetened proposal (second revision) at 0.0890 new shares per Segro share, plus a new £2.7 billion partial cash alternative (20% of consideration), valuing Segro at approximately £13.5 billion ($18.2 billion), or 993 pence per share .
• July 17, 2026 — Segro's board rejects the third proposal as well .
• July 19–20, 2026 — Prologis senior executives meet Segro management in London over the weekend to negotiate further .
• July 22, 2026 — Prologis submits its fourth and "best and final" proposal at 0.0920 shares plus up to £3.5 billion in cash, valuing Segro at £14 billion (~$18.8 billion), meeting the Takeover Panel's PUSU deadline .
• July 22, 2026 (same day) — Segro's board issues a statement saying it is "minded to recommend" the revised proposal, a dramatic U-turn from its prior rejections .
• August 12, 2026 — The Segro board extended the PUSU deadline to no later than 5:00 pm BST on this date to allow final due diligence and documentation .

Segro Board's 'Minded to Recommend' Stance

After rejecting three earlier proposals outright, the Segro board on July 22 said it would be willing to recommend the fourth offer to shareholders, provided that confirmatory due diligence is completed and definitive transaction terms are agreed . The board stated it had engaged with Prologis over the preceding weekend and had been clear it would reconsider on a revised proposal . This shift represents a major breakthrough after weeks of public deadlock.

Conditions Still Required for a Formal Deal

A formal firm offer has not yet been made. The following steps remain before a binding transaction is in place:

• Confirmatory due diligence: Segro's board has agreed to open its books to allow Prologis to complete confirmatory due diligence .
• Final terms and documentation: The boards must agree on definitive deal terms and a formal scheme of arrangement or takeover offer document .
• Shareholder and regulatory approvals: The deal would require approval from Segro shareholders and clearance from relevant competition and regulatory authorities.

Prologis has stated this is its final proposal and will not be increased further .

Potential Impact: Creating the World's Largest Logistics Real Estate Group

• Scale: The combined entity would be the world's largest owner and operator of logistics and industrial real estate, with a portfolio spanning North America, Europe, and Asia .
• Combined market capitalization: Prologis (already the largest industrial REIT globally) plus Segro (the UK's largest listed property company and Europe's biggest logistics landlord) would form a dominant global logistics property group .
• Strategic rationale: The deal would give Prologis a deep portfolio in UK and Continental European logistics assets, data centers, and urban warehouses, with significant scale in key markets like London, Paris, Frankfurt, and across the UK "Golden Triangle" .
• UK listing impact: The secondary LSE listing commitment is seen as a significant concession, partly aimed at softening political and market concerns about the loss of another major UK-listed company to a foreign acquirer . Some analysts have expressed skepticism that secondary listings tend not to last, as trading gravitates to the US .
• Market reaction: Segro shares rose more than 4% on the day of the announcement, and the deal is viewed as one of the largest foreign takeovers of a UK-listed company in recent years .

Bottom line: The deal is the most likely outcome now that Segro's board has signaled support, but it remains conditional on confirmatory due diligence, final terms, and shareholder votes. If completed, it would reshape the global logistics real estate landscape.
