REG - State Street Global SEGRO PLC Prologis, Inc. - Form 8.3 - Prologis, Inc.

What happened

State Street Global Advisors filed a Form 8.3 disclosure on 27 October 2026, showing a position in Prologis, Inc. held as of 26 October 2026. The filing states the discloser is also making disclosures in respect of SEGRO plc as another party to the offer.

Confirmed

Global impact / market context

Form 8.3 is a public filing required under the Takeover Code when someone holds 1% or more of a company involved in a potential takeover, which means the position can signal how investors are placed around a deal. It gives other investors a dated snapshot of holdings.

Analyst inference

The disclosure links Prologis and SEGRO plc through a possible offer situation, so the filing is about investor positioning rather than company operations. Such filings can draw attention to both companies because they reveal who holds stakes while a deal is under way.

Analyst inference

What to watch

1. State Street Global Advisors stated it is also making disclosures in respect of SEGRO plc, so further filings from the same discloser may follow. Confirmed
2. The disclosure does not set out any transaction terms or plans, so no action by Prologis or SEGRO should be assumed from this filing alone. Proposed
3. Watch for later Form 8.3 updates that show changed holdings in Prologis or SEGRO, which could indicate how investors are repositioning as the offer situation develops. Analyst inference
