what happened
Threadneedle Asset Management Holdings, a unit of Ameriprise Financial, filed disclosures under the Takeover Code via RNS, and Reuters reported the details. As of October 16, 2026, the firm held 13,843,211 Segro shares, or 1.02% of the capital: 13,409,748 shares (0.99%) and cash-settled derivatives covering 433,463 shares (0.03%). The same day it sold 2,205 shares at GBP 9.17. For Prologis, as of October 15, the position stood at 4,133,653 shares, or 0.43%. The 406-share change reflects a transfer out of a discretionary holding.
why it matters
For the market this is a routine filing: it shows that a large asset manager holds meaningful stakes in both companies, but it adds no new financial figures. Such notices matter to investors in UK and US REITs as a signal of how major holders are positioned during a possible transaction.
