Form 8.3 - The Vanguard Group, Inc.: Prologis, Inc.

What happened

The Vanguard Group filed a Form 8.3 disclosure showing its interests in Prologis, Inc. securities as of 2 November 2026. The filing under the Takeover Code relates to Prologis and notes that Vanguard is also disclosing in respect of SEGRO plc.

Confirmed

Global impact / market context

A Form 8.3 is a public position disclosure required when someone holds 1% or more of relevant securities. It gives investors an early look at who owns a stake in Prologis and SEGRO during a possible takeover situation, which can help them judge ownership concentration.

Analyst inference

The filing links Vanguard, Prologis and SEGRO in a Takeover Code process, suggesting a possible offer across the two property companies. That can change ownership expectations, but the disclosure itself gives no deal terms, price or voting intention.

Analyst inference

What to watch

1. Watch for further Form 8.3 filings or amendments from Vanguard that update its disclosed position in Prologis and SEGRO. Confirmed
2. Company announcements may later set out offer terms or a firm intention, which would define the price and structure for both property companies. Proposed
3. A bid could change ownership of Prologis and SEGRO shares, affecting how investors position themselves and how takeover rules apply to holders. Analyst inference
