 Brazilian supermarket group Grupo Pão de Açúcar SA has signed a deal with drugstore chain RD SA to create a loyalty program joint venture expected to start in the second half of 2020, both companies said on Wednesday. Under the terms of the agreement, which is still subject to approval by local antitrust regulator Cade, GPA, the local subsidiary of Frances Casino Guichard Perrachon SA, will have a 66.7 stake in the joint venture and RD the remaining 33.7, they said in a securities filing. Called Stix Fidelidade, the new loyalty program is a push to broaden their customer base, as well as shopping frequency for both companies, GPAs Chief Executive Peter Estermann told journalists on Wednesday.
