The clear emerging threat for Kirby (KEX) is the rapid technological shift towards alternative propulsion and power generation technologies across the marine, industrial, and oil & gas sectors. This includes the increasing adoption of electrification, hydrogen, ammonia, methanol, and LNG-fueled powertrains. Kirby's Distribution and Services segment primarily focuses on the sale and servicing of traditional internal combustion engines and related equipment. Should these industries transition away from conventional fossil fuel engines at an accelerating pace, demand for Kirby's core offerings in this segment could significantly diminish, mirroring the disruption seen with older technologies displaced by newer, more advanced alternatives.

Kirby Corporation (KEX) operates primarily in two main segments: Marine Transportation and Distribution and Services. The addressable market sizes for their main products and services, with regional clarification, are as follows:

• Marine Transportation (Inland): The addressable market for Inland Water Transportation in the United States is estimated at $9.5 billion in 2025. This segment includes the transport of liquid bulk cargoes such as petrochemicals, refined petroleum products, and agricultural chemicals across major U.S. waterways like the Mississippi River System and the Gulf Intracoastal Waterway.
• Marine Transportation (Coastal): null
• Distribution and Services (Oil & Gas Field Services): The addressable market for the Oil & Gas Field Services industry in the United States is $109.8 billion in 2025. This segment provides essential aftermarket support, including diesel engine services and parts for the oilfield services sector.
• Distribution and Services (Other Industrial, Marine, and Power Generation Diesel Engine Services): null

Here are 3-5 expected drivers of future revenue growth for Kirby (KEX) over the next 2-3 years:

1. Robust Demand and Pricing in Coastal Marine Transportation: Kirby anticipates continued strong market fundamentals in its Coastal Marine segment, characterized by consistent customer demand and high barge utilization rates, projected to be in the mid-90% range. This favorable supply-demand dynamic, coupled with limited new vessel construction in the industry, is expected to support ongoing pricing gains and drive revenue growth, with full-year revenues for coastal marine expected to increase by high single to low double digits year-over-year in 2025.
2. Strong Growth in Power Generation for Data Centers and Industrial Customers: The Distribution and Services segment is experiencing significant revenue growth driven by robust demand for power generation and backup power installations, particularly from data centers and other industrial customers. This demand has led to a healthy backlog of power generation projects, with revenues in this area increasing 56% year-over-year in Q3 2025. This trend is expected to continue with strong order growth.
3. Improving Pricing and Utilization in Inland Marine Transportation: While facing some near-term softness in spot pricing during Q3 2025, Kirby expects the inland marine market to firm up, with positive momentum in pricing anticipated in the coming quarters. Customer activity remains steady, and the company benefits from disciplined pricing strategies and operational focus.
4. Favorable Industry Supply Dynamics: Across its marine transportation segments, limited new barge construction in the industry plays a crucial role in supporting demand for Kirby's existing transportation services. This constrained supply helps maintain high utilization rates and contributes to the company's ability to achieve pricing gains.
