What to watch

1. Threadneedle's Form 8.3 was dated 23 October 2026 and published by RNS on 26 October 2026, naming Prologis, Inc. as the offeror or offeree and SEGRO PLC as another party. Confirmed
2. The article text cuts off before the positions section, so details of Threadneedle's actual holdings, short positions, and any dealings are not shown and would need to be read in the full form. Proposed
3. Investors could watch for further Rule 8.3 filings from Threadneedle or other holders of 1% or more, because changing stakes may signal how the offer for Prologis develops. Analyst inference
