Cleveland Cliffs is a leading flat-rolled steel producer and supplier of iron ore pellets in North America. The company generates revenue primarily through the production and sale of steel products and iron ore to various industries, including automotive, infrastructure, and manufacturing. Founded in 1847, Cleveland Cliffs has a rich history in mining and steel production, having evolved from a mining company into a fully integrated steel producer. The acquisition of AK Steel in 2020 and ArcelorMittal USA in the same year significantly expanded its capabilities and market presence, making it a key player in the North American steel industry.
