NEWS RELEASE

FOR IMMEDIATE RELEASE

GATX CORPORATION REPORTS 2026 SECOND-QUARTER RESULTS

•Company raises 2026 full-year earnings guidance to $9.90–$10.30 per diluted share

•Rail North America's utilization for the combined fleet remains high at 98.0% at quarter end

•Demand for aircraft spare engines remains strong

•Investment volume was $200.5 million in the second quarter and totaled $4.7 billion year to date

CHICAGO, July 30, 2026—GATX Corporation (NYSE: GATX) today reported 2026 second-quarter net income attributable to GATX of $103.4 million, or $2.84 per diluted share, compared to net income attributable to GATX of $75.5 million, or $2.06 per diluted share, in the second quarter of 2025.

Net income attributable to GATX for the first six months of 2026 was $188.9 million, or $5.19 per diluted share, compared to $154.1 million, or $4.21 per diluted share, in the prior year period.

"GATX delivered strong second-quarter results," said Robert C. Lyons, president and chief executive officer of GATX. "At Rail North America, fleet demand remained stable for most car types. Utilization of the combined fleet remained high at 98.0% at quarter end, while the renewal lease rate change of GATX’s Lease Price Index was 16.8% with an average renewal term of 54 months. Also, our second-quarter renewal success rate was strong at 82.6%. Our team has done an outstanding job integrating the Wells Fargo Rail fleet, and we are seeing incremental benefits related to the acquisition, both commercially and operationally. We did experience an abnormally high volume of railcar renewals in sand service during the quarter, including some carried over from the period immediately following the acquisition, which placed pressure on second-quarter LPI. Demand for railcars in the secondary market was very strong, as we continue to see robust interest in GATX assets from a broad and deep buyer universe. We generated $67.7 million of gains on asset dispositions in the quarter, bringing our year-to-date total to $117.5 million.

"At Rail International, GATX Rail Europe's fleet utilization was 95.3% at quarter end, a modest increase from the previous quarter and a very positive outcome given the generally tepid economic conditions across Europe. GATX Rail India's fleet remains fully utilized, reflecting robust demand for railcars in India."

Mr. Lyons added, "Engine Leasing performed well as demand for aircraft spare engines remains strong. Global air passenger traffic trends have remained healthy year to date despite the ongoing conflict in the Middle East. We continue to

identify attractive aircraft engine investment opportunities, with the RRPF affiliates investing over $660 million year to date."

Mr. Lyons concluded, "We are increasing our 2026 full-year earnings estimate to be in the range of $9.90 – $10.30 per diluted share. This increase reflects several positive factors: strong operating performance and contributions from each of our segments year to date, favorable supply-demand dynamics that are driving the North American rail market, the pace of integration and positive impacts generated by the Wells Fargo Rail acquisition, and the expectation that our teams across GATX will continue executing at a high level. Combined with disciplined investment in our core markets, we believe we are well-positioned to continue generating attractive growth and returns for our shareholders."

RAIL NORTH AMERICA

Rail North America reported segment profit of $118.5 million in the second quarter of 2026, compared to $96.6 million in the second quarter of 2025. Year to date 2026, Rail North America reported segment profit of $222.4 million, compared to $185.4 million in the same period of 2025. Higher 2026 second-quarter and year-to-date results were driven by higher revenues and higher gains on asset dispositions, partly offset by higher interest, depreciation and maintenance expenses.

As of June 30, 2026, Rail North America’s fleet totaled approximately 201,800 cars, including over 9,100 boxcars. The following fleet statistics and performance discussion exclude the boxcar fleet.

Fleet utilization was 98.0% at the end of the second quarter of 2026, compared to 98.1% at the end of the prior quarter, driven by the acquisition of the Wells Fargo Rail's fleet, and 99.2% at the end of the second quarter of 2025. During the second quarter of 2026, the renewal lease rate change of the Lease Price Index (LPI) was positive 16.8%, compared to 22.3% in the prior quarter and 24.2% in the second quarter of 2025. The average lease renewal term for all cars included in the LPI during the second quarter of 2026 was 54 months, compared to 56 months in the prior quarter and 60 months in the second quarter of 2025. The 2026 second-quarter renewal success rate was 82.6%, compared to 79.1% in the prior quarter and 84.2% in the second quarter of 2025. Rail North America’s investment volume during the second quarter of 2026 was $147.1 million.

Additional fleet statistics, including information on the boxcar fleet, and macroeconomic data related to Rail North America’s business are provided in the attached Supplemental Information under Rail North America Statistics.

RAIL INTERNATIONAL

Rail International’s segment profit was $31.6 million in the second quarter of 2026, compared to $32.2 million in the second quarter of 2025. Year to date 2026, Rail International reported segment profit of $63.2 million, compared to $57.9 million in the same period of 2025. 2026 second-quarter and year-to-date results were favorably impacted by more railcars on lease, including railcars acquired from DB Cargo in a sale-leaseback transaction, and negatively impacted by higher depreciation and interest expenses.

As of June 30, 2026, GATX Rail Europe’s (GRE) fleet consisted of approximately 36,700 cars. Fleet utilization was 95.3%, compared to 94.7% at the end of the prior quarter and 93.3% at the end of the second quarter of 2025.

As of June 30, 2026, Rail India's fleet consisted of over 12,800 railcars. Fleet utilization was 100.0%, compared to 100.0% at the end of the prior quarter and 99.6% at the end of the second quarter of 2025.

Rail International’s investment volume during the second quarter of 2026 was $45.6 million.

Additional fleet statistics for GRE and Rail India are provided on the last page of this press release.

ENGINE LEASING

Engine Leasing reported segment profit of $66.4 million in the second quarter of 2026, compared to segment profit of $27.3 million in the second quarter of 2025. Year to date 2026, segment profit was $101.7 million, compared to segment profit of $65.9 million in the same period of 2025.

Higher 2026 second-quarter and year-to-date results were primarily driven by strong performance at the Rolls-Royce and Partners Finance (RRPF) affiliates. In the second quarter of 2026, both operating and remarketing income at RRPF were higher compared with the same period in 2025.

As of June 30, 2026, RRPF's portfolio, 50% of which is owned by GATX, consisted of 468 aircraft engines.

As of June 30, 2026, GATX Engine Leasing, the Company’s wholly owned engine portfolio, consisted of 46 aircraft engines.

_________

(1) GATX's Lease Price Index (LPI) is an internally-generated business indicator that measures renewal activity for our North American railcar fleet, excluding boxcars. The LPI calculation includes all renewal activity based on a 12-month trailing average, and the renewals are weighted by the count of all renewals over the 12-month period. The average renewal lease rate change is reported as the percentage change between the average renewal lease rate and the average expiring lease rate. The average renewal lease term is reported in months and reflects the average renewal lease term in the LPI.

(2) The renewal success rate represents the percentage of railcars on expiring leases that were renewed with the existing lessee. The renewal success rate is an important metric because railcars returned by our customers may remain idle or incur additional maintenance and freight costs prior to being leased to new customers.

(3) Excludes boxcar fleet.

(4) As reported and revised by the Federal Reserve.

(5) As reported by the Association of American Railroads (AAR).

(6) As reported by the Railway Supply Institute (RSI).
