Dimensional Fund Advisors LP Reaches 5.001007% Stake in TP ICAP on 5 November 2026

According to the TR-1 notification, Dimensional Fund Advisors LP held 36,225,288 voting rights in TP ICAP Group plc as of 5 November 2026, representing 5.001007% of total voting rights. All of these rights are attached directly to ordinary shares under ISIN JE00BMDZN391, with zero voting rights held through financial instruments. The threshold was crossed or reached on 5 November 2026, and TP ICAP was formally notified on 9 November 2026, in accordance with standard regulatory timelines under the Disclosure Guidance and Transparency Rules.

Shares Held Across Segregated Accounts Managed by Dimensional's Global Subsidiaries

The announcement states that the ordinary shares are held in segregated accounts and funds managed on a discretionary basis by Dimensional Fund Advisors LP and five subsidiary undertakings: Dimensional Fund Advisors Ltd., DFA Australia Limited, Dimensional Ireland Limited, Dimensional Fund Advisors Canada ULC, and Dimensional Fund Advisors Pte. Ltd. Dimensional Fund Advisors LP is controlled by its general partner, Dimensional Holdings Inc. The notification further discloses that Dimensional expressly disclaims beneficial ownership of the shares held within these accounts, a standard clarification for discretionary asset managers operating across multiple jurisdictions.

Additional 101,268 Shares Under Dimensional's Investment Discretion but Outside Its Voting Control

The announcement also notes that as of 5 November 2026, Dimensional Fund Advisors LP had investment management discretion over an additional 101,268 shares held within the same accounts, where the voting rights are not controlled by Dimensional or its subsidiaries. This distinction is relevant because these shares are excluded from the 5.001007% voting rights figure disclosed in the notification. The separation between investment discretion and voting control is a common structural feature of large institutional managers operating pooled and segregated mandates across multiple entities globally.
