Skanska AB is a global construction and project development firm that operates through four primary business segments: Construction, Residential Development, Commercial Property Development, and Investment Properties. The Construction segment is the company's core business, generating the vast majority of its revenue (typically over 90%) and operating income. This segment functions as a large-scale contractor, building non-residential and civil infrastructure such as schools, hospitals, mass transit systems, airports, highways, bridges, data centers, and commercial offices, alongside some residential multifamily buildings. The Residential Development segment focuses on developing and building single and multifamily homes for immediate sale, primarily in the Nordics and Central Europe. The Commercial Property Development segment initiates, develops, leases, and divests commercial properties, including office buildings, logistics centers, and life-science facilities. Finally, the Investment Properties segment actively manages a portfolio of high-quality office properties, primarily in Sweden, to generate stable cash flows. Geographically, Skanska's operations are concentrated in the Nordics (Sweden, Norway, Finland), other parts of Europe (including the UK, Poland, and the Czech Republic), and the United States, which represents its largest market by revenue. The company's competitive position is supported by its extensive expertise in complex public-private partnerships (PPPs) and large-scale civil engineering projects.
