CMA begins formal Phase 1 inquiry into McCormick and Unilever merger
The UK CMA has started a Phase 1 inquiry into McCormick & Co's $44B acquisition of Unilever's food business, which includes brands like Marmite and Horlicks. The deal, announced in March 2026, aims to streamline Unilever's portfolio. Unilever is also selling Colman's mustard to address competition concerns, as McCormick owns French's mustard.
