Form 8.3 - The Vanguard Group, Inc.: Intertek Group plc

What happened

The Vanguard Group, Inc. filed a Form 8.3 public opening position disclosure on 30 October 2026 for Intertek Group plc. The form states the position was held or the dealing undertaken on 29 October 2026, and that no disclosures were being made for any other party to the offer.

Confirmed

Global impact / market context

A Form 8.3 is a public disclosure under the Takeover Code, which is the rulebook for UK company takeovers. It shows that Vanguard holds a stake of 1% or more in Intertek, helping other investors see how a large holder is positioned while a takeover situation is live.

Analyst inference

The disclosure signals that Intertek is involved in an offer or possible offer, because Form 8.3 is filed by persons with interests in relevant securities of an offeror or offeree. It gives investors visibility on a large holder's position, which can matter for how the deal is assessed and for trading around it.

Analyst inference

What to watch

1. Watch for further Form 8.3 disclosures from Vanguard, because the form states a separate form is used for each offeror or offeree and positions can be updated. Confirmed
2. Watch for any formal offer document or scheme document for Intertek, which would set out the proposed terms and timetable for shareholders to consider. Proposed
3. Watch whether Vanguard's disclosed holding changes in later filings, since a larger or smaller stake could shift the balance of shareholder support for a deal. Analyst inference
