Summary
- Prologis has disclosed an indicative all-share proposal for SEGRO, valuing the company at about £12.6bn.
- SEGRO rejected the approach, with Prologis required to make a firm offer or walk away by 22 July 2026.
- Prologis specifically highlighted SEGRO’s development, power, and data centre opportunities as part of the strategic rationale.
Prologis has disclosed an indicative all-share proposal for SEGRO, valuing the UK-listed industrial property group at approximately £12.6bn and pulling data centre pipeline value into a public takeover timetable.
The proposal was sent to SEGRO’s board on 16 June and rejected on 23 June. Under the terms set out by Prologis, SEGRO shareholders would receive 0.084 new Prologis shares for each SEGRO share. Based on Prologis’s share price and the relevant exchange rate at market close on 23 June, the proposal implied a value of 925p per SEGRO share.
Prologis said the approach represented a 24.6% premium to SEGRO’s closing share price on 23 June and valued the company in line with its last reported EPRA net tangible assets per share at 31 December 2025. SEGRO shareholders would own about 10.5% of the enlarged Prologis share capital if a deal completed.
The Rule 2.4 announcement gives Prologis until 5pm London time on 22 July 2026 to announce a firm intention to make an offer or state that it does not intend to do so, unless the Takeover Panel extends the deadline.
Land value now includes megawatts
Prologis and SEGRO are industrial real estate businesses, not data centre operators. Yet Prologis’s rationale explicitly refers to SEGRO’s development, power, and data centre opportunities. That framing shows how data centre demand is changing the valuation of industrial land and logistics estates.
Warehouses, business parks, and industrial estates close to major demand centres can carry hidden value if they also have access to power, fibre, planning precedent, and developable land. In older real estate models, a site might be assessed around logistics rent, location, and occupancy. In the AI infrastructure market, the same site may also be valued for the megawatts it can unlock.
SEGRO’s Slough Trading Estate sits at the centre of that shift. Slough is one of Europe’s most important data centre clusters, shaped by proximity to London, strong connectivity, and substantial electricity infrastructure. As AI and cloud demand increase, the estate’s power position becomes a strategic asset rather than a background utility detail.
Prologis argues that its global platform, balance sheet strength, and access to capital could accelerate delivery of SEGRO’s development and data centre pipeline. The logic is financial as much as operational. Data centre developments require large upfront capital, long delivery programmes, and confidence that power, planning, and customer commitments will arrive in the right sequence.
A pipeline still has to become capacity
The hard part is turning pipeline value into operational capacity. Land near a strong market is not enough. Developers need substations, connection agreements, planning consent, transformer supply, cooling design, construction labour, tenant demand, and finance that can withstand a long build cycle.
That is why data centre optionality is becoming harder to price. A site with a clear grid connection date, planning support, and a credible customer path is a different asset from land described as capable of future data centre use. The difference can decide whether a pipeline deserves a premium or a discount.
Prologis’s proposal also arrives in a UK market where listed real estate companies have often traded below reported asset value. The added data centre component gives investors another lens through which to view the gap between share price and underlying assets. If power-led land has not been fully priced, strategic buyers may try to capture that value before it becomes more visible.
SEGRO’s rejection keeps the process open. Shareholders now have a deadline, a disclosed premium, and a strategic argument built around scale, capital access, and data centre opportunity. Rival interest is possible, although no firm offer has yet been made.
For the data centre sector, the approach is a reminder that capacity growth can start long before a data hall is designed. Control of the estate, the grid route, and the capital stack can determine where the next campus is built. In Slough and other constrained European markets, the landowner with power may hold the most valuable part of the chain.
