Headquartered in Houston, Texas, Kirby Corporation operates through two primary business segments: Marine Transportation and Distribution and Services. The Marine Transportation segment, which accounts for the majority of its revenue, operates over 1,000 inland tank barges and a fleet of coastal vessels, moving essential liquid cargoes for major petrochemical and refining customers. The Distribution and Services segment serves as a distributor and aftermarket service provider for medium- and high-speed diesel engines, reduction gears, and ancillary products. This segment also manufactures and remanufactures oilfield service equipment, including pressure pumping units, and provides power generation equipment and energy storage systems. By combining its dominant position in U.S. inland marine transport with a diversified industrial services business, Kirby maintains a critical role in the domestic supply chain for energy and chemical products.
