About KIRBY CORP

Kirby Corp. (NYSE: KEX), headquartered in Houston, Texas, in the United States, is a specialized industrial and logistics company whose business is built around U.S. marine transportation and technical distribution/services. Its corporate history dates back to 1921, when John Henry Kirby formed Kirby Petroleum Company. The company later went through major restructurings, began trading under the KEX ticker in 1976, and adopted the Kirby Corporation name in 1990. For international equity investors, Kirby is best understood as a domestic U.S. infrastructure and freight specialist with a meaningful aftermarket services arm. Kirby operates through two reportable segments. The first is Marine Transportation, the company’s core franchise. Kirby moves petrochemicals, refined products, black oil, agricultural chemicals and other liquid cargoes on the U.S. inland waterway system and along the country’s coastlines. Its fleet of tank barges and towboats operates under the U.S. flag and qualifies for Jones Act trade, which creates a meaningful regulatory moat. Kirby’s network spans the Mississippi River system, interconnected inland waterways and the Gulf Intracoastal Waterway, giving the company a large operating footprint in domestic bulk liquid logistics. Kirby describes itself as the largest domestic liquid tank barge operator in the United States, a position that supports scale, customer relationships and fleet utilization discipline. The second segment, Distribution and Services, is a diversified equipment and aftermarket business operated through Stewart & Stevenson, United Holdings and Kirby Engine Systems. This segment supplies and services power generation equipment, engines, transmissions, parts, industrial equipment and oilfield services equipment. End markets include power generation, commercial and industrial, marine repair, on-highway and oil and gas. In recent quarters, power generation has been an important growth driver, supported by demand for backup power, critical power applications and data-center related projects. From a competitive standpoint, Kirby benefits from a leading niche position, high asset intensity and strong entry barriers, particularly in the Jones Act-regulated marine market. The company’s recent results have shown resilience: it reported higher earnings and revenue in Q1 2026, following solid 2025 quarters, with favorable conditions in inland marine transportation and healthy demand in distribution and services. This combination gives Kirby a balanced profile: cyclical exposure to U.S. industrial activity, but also a structural position in essential domestic freight and equipment support services. Kirby is listed on the NYSE in the United States, and remains a notable name for investors seeking exposure to U.S. inland waterways, coastal freight, and industrial aftermarket services.
