Gränges AB (publ) (GRNG.ST) Stock Analysis & Winston Score

Gränges AB is a Swedish company that makes rolled aluminum — thin, flat sheets of aluminum used in products like car radiators, heat exchangers, and packaging. Its main customers are automakers and industrial manufacturers who need lightweight, heat-resistant metal parts. Gränges is one of the largest producers of rolled aluminum products in the world, with a strong focus on thermal management applications. The company earns money by selling aluminum sheet products, with revenue tied closely to the volume of metal it processes and the premium it charges for specialized alloys and coatings. Gränges operates globally, with manufacturing facilities in Europe, Asia, and the Americas, and generates several billion Swedish kronor in annual revenue. Its competitive edge comes from deep technical expertise in aluminum alloys and long-term supply relationships with major automotive customers. The key growth driver is the shift toward electric vehicles, which require more advanced thermal management systems — but the business also faces risk from slowing auto production and volatile aluminum input costs.
