JCDecaux SE is a global leader in the out-of-home advertising industry, operating across more than 80 countries. The company's business is structured into three primary segments: Street Furniture, Transport, and Billboard advertising. Its Street Furniture division, the largest revenue contributor, involves installing and maintaining public amenities such as bus shelters, automated toilets, and self-service bicycle networks in exchange for advertising rights. The Transport segment manages advertising concessions in airports, train stations, and metro systems worldwide. Additionally, the Billboard segment offers large-format traditional and illuminated advertising on private properties. In recent years, JCDecaux has increasingly focused on digital out-of-home (DOOH) and programmatic advertising to drive growth and enhance its urban infrastructure offerings.
