Here are 1-3 brief analogies to describe GATX:

• Hertz for freight trains
• Ryder for railcars
• United Rentals for industrial rail equipment

• Railcar Leasing: GATX provides operating leases for a diverse fleet of freight railcars, including tank cars, freight cars, and locomotives, to customers across various industries primarily in North America, Europe, and India.
• Marine Leasing: GATX offers operating leases for tankerman vessels, which are utilized for the transportation of petroleum products and chemicals, predominantly in North America.

GATX Corporation (NYSE: GATX) primarily sells its services (leasing of railcars, marine vessels, and other assets) to other companies.

According to its latest financial filings, GATX has a diverse customer base and does not have any single customer that accounts for a significant portion of its total revenues. The largest single customer represented less than 3% of total revenues in recent fiscal years. Therefore, it is not possible to list specific "major customer" companies by name.

Instead, GATX serves various categories of businesses across its operating segments:

• Railroads and Rail Transportation Providers: These include major freight railroads and other companies that provide rail transportation and logistics services, utilizing GATX's leased railcars for their operations or for their own customers.
• Industrial Companies and Shippers: A broad category encompassing businesses across various sectors such as chemical producers, petroleum companies, agricultural businesses, energy companies, and manufacturers. These companies lease railcars to transport their raw materials or finished products, or marine vessels for the bulk transportation of liquids like petroleum products and chemicals.

• The Greenbrier Companies (NYSE: GBX)

1. Decarbonization and Technological Shifts in Maritime and Rail Propulsion Systems

The global push for decarbonization and stringent environmental regulations are driving rapid technological advancements in both the maritime and rail sectors. For GATX's marine segment, there's an accelerating shift towards alternative fuels (e.g., LNG, methanol, ammonia, hydrogen) and hybrid-electric propulsion systems to meet evolving IMO targets and customer demands for greener shipping. This threatens to accelerate the obsolescence of GATX's existing conventional marine fleet and requires significant new capital investment in technologies with uncertain long-term viability and infrastructure.

Similarly, in the locomotive leasing business, major rail operators (e.g., Union Pacific, CN, BNSF) are actively piloting battery-electric and hydrogen fuel cell locomotives from suppliers like Wabtec and Progress Rail. Governments are also incentivizing cleaner transportation. If these alternative propulsion systems mature rapidly and gain widespread adoption, GATX's substantial fleet of diesel locomotives could face accelerated depreciation, reduced lease rates, or require costly conversions and new investments to remain competitive.

2. Advancements in Autonomous Long-Haul Trucking

The rapid development and increasing viability of autonomous long-haul trucking technology pose an emerging threat to the rail freight industry, and consequently, to railcar lessors like GATX. Companies such as Waymo Via, Aurora, and Kodiak Robotics, often in partnership with traditional trucking giants, are actively testing and deploying autonomous trucks in commercial pilot programs across various states. As this technology progresses towards widespread adoption and regulatory approval, it could offer a highly efficient, 24/7, and potentially lower-cost alternative for certain types of freight currently transported by rail, particularly intermodal and high-value goods where point-to-point delivery speed and flexibility are critical. This could divert freight volumes from rail to road, leading to reduced demand for railcars and downward pressure on lease rates for GATX.

1. Strategic Acquisitions: GATX anticipates revenue growth from the pending acquisitions of rail assets. Specifically, the acquisition of 105,000 railcars from Wells Fargo (via a joint venture) and 6,000 railcars from DB Cargo AG are expected to close in Q1 2026 and Q4 2025, respectively, and contribute to future financial performance.
2. Strength and Investment in Engine Leasing: The company's engine leasing business is a strong performer, with management anticipating continued robustness and plans to invest approximately $200 million in its engine portfolio. This segment has shown significant growth, with segment profit increasing to $60.4 million in Q3 2025 from $37.5 million in Q3 2024.
3. Increased Lease Rates and Extended Terms for Railcars: GATX has been experiencing stable demand for its North American railcar fleet, achieving strong renewal lease rate increases. The renewal lease rate change of the Lease Price Index (LPI) was positive 22.8% in Q3 2025, with an average renewal term of 60 months, indicating enhanced monetization of its existing fleet.
4. Robust Secondary Market for Asset Sales: The continued strength in the secondary market for asset sales, particularly in North America, and the resulting remarketing income, are expected to drive revenue. Management projects no material change in secondary market demand or remarketing income levels through 2027.
5. Placement of New Railcars from Supply Agreements: GATX continues to successfully place new railcars from its committed supply agreements with a diverse customer base. For instance, over 6,500 railcars have been placed from its 2022 Trinity supply agreement, with the earliest scheduled deliveries under this agreement extending into 2026.
