NYAB AB operates as a pan-Nordic engineering, procurement, and construction (EPC) specialist, with a strong focus on sustainable infrastructure and renewable energy projects. The company's business segments encompass civil engineering, consulting, and specialized construction services tailored for heavy industry and energy networks. NYAB's geographic footprint is concentrated in Sweden and Finland, where it handles complex projects such as wind and solar power installations, power grid expansions, and traditional infrastructure like roads and bridges. The firm's competitive position is bolstered by its expertise in subarctic logistics and its ability to manage complex permitting processes for large-scale renewable initiatives. Originally founded in 1990 and significantly expanded through a 2022 merger with the Finnish Skarta Group, NYAB re-domiciled to Sweden in 2024 to further consolidate its market presence in the Nordic industrial transition.
