Announcement by Castel Group of the acquisition of Diageo’s stake in Guinness Ghana Breweries Plc (a company listed on the Ghana Stock Exchange)

7 July 2025, Luxembourg - Further to Castel group’s announcement dated 28 February 2025 on its intention to acquire Diageo Holdings Netherlands B.V.’s (“Diageo”) 80.4% stake in Guinness Ghana Breweries PLC (“Guinness Ghana”), Castel group hereby informs the market that it has received approval from the ECOWAS Regional Competition Authority to proceed with the acquisition.

Accordingly, pursuant to a share purchase agreement signed on 28 January 2025, Castel group has acquired Diageo’s 247,291,361 ordinary shares in Guinness Ghana at a price of GHS 5.15 per share.

The acquisition triggers the mandatory takeover requirements under the Securities and Exchange
Commission’s Code on Takeovers and Mergers, 2008.

However, based on the strategic plans that Castel group has for the growth of Guinness Ghana, Castel has requested an exemption from the mandatory takeover requirements, which has been granted by the Securities and Exchange Commission (SEC) on 3 July 2025. Accordingly, Castel group will not be making an offer to acquire the shares of the remaining shareholders of Guinness Ghana.
