REG - UBS Asset Management Prologis, Inc. - Form 8.3 - PROLOGIS INC

What happened

UBS Asset Management filed a Form 8.3 opening position disclosure concerning Prologis Inc., dated 4 November 2026. It states that the position date was 3 November and that UBS was also making disclosures in respect of SEGRO plc.

Confirmed

Global impact / market context

The filing links UBS’s disclosed position reporting to both Prologis and SEGRO, but the supplied text does not show the position amounts or whether UBS bought or sold shares. Without those details, investors cannot judge the size or direction of any potential effect on share demand.

Analyst inference

This is a takeover-related disclosure under Rule 8.3, which covers relevant securities positions or dealings by a person with interests representing at least 1%. The excerpt identifies the companies and disclosure dates but omits the detailed positions, so it does not establish a transaction or change in ownership.

Confirmed

What to watch

1. Check the remainder of the filing for the number and type of Prologis securities reported; those details would show the scale of UBS’s disclosed position. Analyst inference
2. Review the SEGRO disclosure details and any later filings for changes in positions or dealings, which could clarify UBS’s involvement in the offer-related process. Analyst inference
3. The supplied excerpt confirms UBS named SEGRO plc as another party covered by its disclosure, but provides no specific SEGRO holding or dealing details. Confirmed
