F rancisco Jose Riberas Mera is a Spanish industrial billionaire who, along with his brother Jon, controls one of the world's leading automotive components manufacturers, Gestamp. The business was founded by their late father, who started a steel trading company. The brothers inherited the business and transformed it into a global industrial powerhouse. Francisco serves as the Executive Chairman of Gestamp.

Gestamp specializes in the design and manufacturing of metal automotive components, particularly in body-in-white and chassis systems, which are critical for the structure and safety of vehicles. Francisco has been the driving force behind Gestamp's massive global expansion, building a network of factories around the world to serve major automakers like Volkswagen and Renault directly in their key markets. He took the company public in a major IPO on the Madrid stock exchange in 2017. While he leads Gestamp, his brother Jon runs the family's other industrial holdings through their investment arm, Acek.
