EL SEGUNDO, Calif. — Beyond Meat, Inc. has entered strategic partnerships with McDonald’s Corp., Chicago, and Yum! Brands, Inc., Louisville, Ky., two of the largest fast-food companies. The agreements will make Beyond Meat a partner with both companies to co-develop plant-based menu items. The McDonald’s agreement goes a step further and names Beyond Meat as McDonald’s “preferred supplier” for the patty in the McPlant sandwich, a plant-based item currently in test markets. The partnership with Yum! Brands is an expansion of the companies’ earlier collaborations. . . .
