This document provides an overview of Kirby Corporation, one of the largest inland barge operators in the United States. Kirby operates over 900 tank barges and 240 towboats, moving over 17 million barrels of petroleum and other liquid products annually. It has been in business since 1921 and dominates the liquid inland marine transportation industry, with a consistent record of stock growth and awards for safety and environmental protection. Some opportunities for Kirby include acquiring other barge companies, replacing older barges, and reducing emissions. Threats include hurricanes, slowdowns at refineries, and damage to infrastructure.
