What happened

Threadneedle Asset Management Holdings Ltd filed a Form 8.3 opening-position disclosure concerning Prologis, Inc., with SEGRO Plc also named as another party to the offer. The disclosure says the position was held on 30 October 2026 and identifies Ameriprise Financial, Inc. as Threadneedle’s ultimate parent.

Confirmed

Global impact / market context

The filing signals that Threadneedle, a fund and portfolio management business, has a reportable interest connected with Prologis. Such disclosures can give investors visibility into institutional positioning during an offer process, but the supplied text does not state the size or direction of the position.

Analyst inference

The document is an opening-position disclosure under Rule 8.3 of the Takeover Code, a rule requiring disclosure of interests in relevant securities of 1% or more. It names Prologis and SEGRO, but provides no transaction terms or position details in the supplied excerpt.

Confirmed

What to watch

1. Check the complete filing for the number and type of Prologis securities disclosed; the excerpt ends before the positions section and does not reveal whether the interest is shares or another instrument. Analyst inference
2. Look for subsequent dealing disclosures from Threadneedle, which would report changes in its interests and help show whether its disclosed position grows, falls, or changes form. Analyst inference
3. The filing identifies 30 October 2026 as the position date and names SEGRO as another offer party; the excerpt gives no offer terms or outcome. Confirmed
