REG - Northern Trust Corp SEGRO PLC - Form 8.3 - Prologis, Inc

What happened

Northern Trust Corporation filed a public opening position disclosure under Rule 8.3 of the Takeover Code on 27 October 2026, relating to Prologis, Inc. The relevant position or dealing was dated 26 October 2026, and Northern Trust also stated it is making disclosures for SEGRO plc.

Confirmed

Global impact / market context

The filing shows Northern Trust holds or controls relevant Prologis securities representing 1% or more, so its position must be disclosed under the Takeover Code. Because Northern Trust also discloses for SEGRO plc, investors can see it is connected to both sides of a possible deal, which may affect how they view trading interest.

Analyst inference

Rule 8.3 disclosures give a public view of large holders' positions and dealings during a takeover situation. The link between Prologis and SEGRO plc suggests a possible offer involving the two property companies, so investors may focus on their shares for signs of deal progress or shifting ownership.

Analyst inference

What to watch

1. Any further Rule 8.3 filings by Northern Trust Corporation in relation to Prologis, Inc. or SEGRO plc, because each new disclosure would show changes in its disclosed position or dealings. Confirmed
2. Whether Prologis, Inc. and SEGRO plc confirm a firm offer or a possible cash offer, which would move the situation beyond a disclosure and give shareholders clearer terms to assess. Proposed
3. The size and direction of Northern Trust's disclosed holdings, since a rising or falling stake in either company could signal changing investor positioning around the possible deal. Analyst inference
