How the Company Makes MoneyKirby Corporation generates revenue primarily through two main segments: Marine Transportation and Diesel Engine Services. The Marine Transportation segment is the largest contributor, where Kirby operates a fleet of inland and coastal tank barges and towing vessels, generating income by providing transportation services for a variety of liquid cargoes. The Diesel Engine Services segment earns revenue by providing overhaul and repair services for engines, sales of engine parts, and field services. Kirby's earnings are significantly influenced by the demand in the petrochemical and refining industries, changes in oil prices, and the overall economic climate affecting its key markets.
