Rule 2.4 of the City Code on Takeovers and Mergers is the disclosure mechanism that forces companies into the open before any formal offer is made. Under it, parties to a possible deal must acknowledge discussions publicly once those discussions cross a threshold the Takeover Panel considers material. SEGRO and Prologis have now filed under that rule, issuing a further announcement that a possible combination between the two companies is under consideration.
The Rule 2.4 mechanism
Filing under Rule 2.4 does not confirm a transaction. It confirms that discussions have reached a stage where the Code demands transparency. The "further announcement" label in the filing title signals that at least one prior public disclosure in this sequence already exists, placing this release inside an ongoing disclosure track rather than at the beginning of one.
The Takeover Panel's City Code operates on firm timeline logic: once a party files under Rule 2.4, the clock runs toward either a firm offer announcement or a public statement that no offer will be made. Neither outcome is disclosed here.
What the announcement does not say
No financial terms appear. No consideration, no exchange structure, no valuation, no indicative timeline. The announcement carries a jurisdictional distribution restriction, the standard City Code caveat covering regions where publication would breach local law.
A possible combination between two companies of this profile warrants attention. A filing with no price discovery, no structure, and no disclosed timeline warrants equal skepticism. The announcement is, at present, exactly what Rule 2.4 is designed to produce: confirmation that something is being discussed, nothing more.
