Communication on the acquisition by CA Indosuez of shares issued by Banque Degroof Petercam SA/NV and on the tender offer that will follow the closing of this acquisition

We refer to the communications published on 4 August 2023, which are attached to this letter, announcing that CA Indosuez Wealth (Europe) has entered into an agreement with certain reference shareholders of BDP (the "Agreement"). This agreement will allow CA Indosuez Wealth (Europe) or any related company that replaces it to hold a majority stake in BDP at the closing of the transaction (the "Closing"). By a letter dated 7 November 2023, CA Indosuez Wealth (Europe) assigned all of its rights and obligations under the Agreement to CA Indosuez, a limited liability company incorporated under the laws of France, having its registered office at rue du Docteur Lancereaux 17, 75008 Paris, registered with the Register of commerce and companies under number 572 171 635 (hereinafter the "Purchaser").

Within 15 business days following Closing, which is expected to occur in the second quarter of 2024, the Purchaser will submit a formal notification to the Financial Services and Markets Authority (FSMA), in order to launch, as soon as possible and at the latest within six months of Closing¹, a voluntary public tender offer on all shares issued by BDP and that are not already held by the Purchaser or CLdN Finance S.A. (which will keep a participation in BDP) (the "Offer"). This Offer will be unconditional and will take place on the same terms and conditions as those of the Agreement, in order to ensure equal treatment between all shareholders, subject only to objectively required differences based on their respective structure.

As a shareholder of BDP, the above mentioned Offer will be directed to you. After Closing, the Purchaser and BDP will contact you in this respect.

In accordance with the applicable regulation, the Purchaser will publish a prospectus that will include the terms of the Offer and contain information that is necessary for you to be able to make an informed judgment on the Offer, taking into account the characteristics of the transaction and BDP. BDP will also publish a response memorandum in accordance with the applicable regulation, which shall include BDP's reasoned opinion on the Offer. The prospectus and the response memorandum must be approved by the FSMA beforehand. Details of how these documents will be made available will be published in due course after Closing and we will keep you informed of such publication.

We invite you to consult BDP’s website (https://www.degroofpetercam.com/fr-be) and the Purchaser’s website (https://ca-indosuez.com/fr), where you will find a list of questions and answers.

This communication is for information purposes only and does not constitute an offer to purchase or invitation to sell securities of BDP, nor a solicitation by anyone in any jurisdiction in respect of such securities.
