Mexico’s Comisión Nacional Antimonopolios (CNA) accepted remedies proposed by GRUMA in a long-running corn masa flour competition case, El Economista reported Jan. 24, closing the proceeding without ordering plant divestitures that investigators had earlier floated.
Under the deal, GRUMA will modify current and future contracts to eliminate exclusivity and minimum-purchase obligations (and related penalties) imposed on tortillería customers, and will cede associated tortilla machines and mixers (tortilladoras and batidoras) at no extra charge via lease, financing, or support structures.
The case traced to a 2022 Cofece inquiry; a 2024 preliminary opinion had cited high regional masa-flour shares and proposed selling several of GRUMA’s Mexican plants. GRUMA argued for contract-focused alternatives instead. Implementation documentation was to be set with CNA on a 90- to 180-day clock.
U.S. plant managers should treat this as a Mexico competition and capacity signal — not a U.S. antitrust ruling — while watching any knock-on effects on masa pricing and cross-border flour flows.
