GATX Corporation (NYSE:GATX) today reported 2023 third-quarter net income of $52.5 million, or $1.44 per diluted share, compared to net income of $29.1 million, or $0.81 per diluted share, in the third quarter of 2022. The 2022 third-quarter results include a net negative impact of $10.8 million, or $0.31 per diluted share, from Tax Adjustments and Other Items.

Net income for the first nine months of 2023 was $193.2 million, or $5.30 per diluted share, compared to $107.5 million, or $2.99 per diluted share, in the prior year period. The 2023 year-to-date results include a net negative impact of $1.1 million, or $0.03 per diluted share, from Tax Adjustments and Other Items. The 2022 year-to-date results include a net negative impact of $55.2 million, or $1.54 per diluted share, from Tax Adjustments and Other Items. Details related to these items are provided in the attached Supplemental Information under Impact of Tax Adjustments and Other Items.

"Consistent with our initial outlook, the railcar leasing environment in North America remains robust," said Robert C. Lyons, president and chief executive officer of GATX. "Rail North America's fleet utilization was 99.3% at the end of the third quarter and our renewal success rate was 83.6%. The renewal lease rate change of GATX's Lease Price Index was positive 33.4% for the quarter, with an average renewal term of 65 months, as we continue to lengthen lease terms on many car types, thereby locking in attractive long-term cash flow.

"Rail International produced solid operating results and added a combined total of over 1,400 newly built railcars to its fleets in Europe and India. In addition, Rail Europe continued to experience higher renewal lease rates compared to expiring rates for the majority of car types in its fleet. In Portfolio Management, results were driven by strong performance at the Rolls-Royce and Partners Finance affiliates, as demand for international air passenger travel continues to strengthen."

Mr. Lyons added, "We continued to execute our strategy of pursuing attractively priced growth opportunities across our global businesses. Investment volume was over $360 million in the quarter and over $1.2 billion year to date."

Mr. Lyons concluded, "Based on year-to-date performance and our outlook for the remainder of the year, we expect our 2023 full-year earnings to modestly exceed the high end of our previously announced guidance range of $6.50–$6.90 per diluted share. This guidance excludes any impact from Tax Adjustments and Other Items."

RAIL NORTH AMERICA

Rail North America reported segment profit of $66.1 million in the third quarter of 2023, compared to $64.3 million in the third quarter of 2022. Year-to-date 2023, Rail North America reported segment profit of $240.6 million, compared to $237.8 million for the same period of 2022. Higher 2023 third-quarter and year-to-date results were due to higher lease revenue and higher gains on asset dispositions, partially offset by higher interest and maintenance expenses.

At Sept. 30, 2023, Rail North America's wholly owned fleet was composed of approximately 109,700 railcars, including over 9,000 boxcars. The following fleet statistics and performance discussion exclude the boxcar fleet.

Fleet utilization was 99.3% at the end of the third quarter, compared to 99.3% at the end of the prior quarter and 99.6% at the end of the third quarter of 2022. During the third quarter, the renewal lease rate change of the GATX Lease Price Index (LPI) was positive 33.4%. This compares to positive 33.1% in the prior quarter and positive 18.8% in the third quarter of 2022. The average lease renewal term for all railcars included in the LPI during the third quarter was 65 months, compared to 61 months in the prior quarter and 52 months in the third quarter of 2022. The 2023 third-quarter renewal success rate was 83.6%, compared to 85.3% in the prior quarter and 87.2% in the third quarter of 2022. Rail North America's investment volume during the third quarter was $197.0 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 $28.2 million in the third quarter of 2023, compared to $14.5 million in the third quarter of 2022. Year-to-date 2023, Rail International reported segment profit of $79.0 million, compared to $67.7 million for the same period of 2022. The third-quarter and year-to-date 2022 segment results include a net negative impact of $10.8 million from Tax Adjustments and Other Items. Additional details are provided in the attached Supplemental Information under Impact of Tax Adjustments and Other Items.

2023 third-quarter results were driven by higher lease revenue, predominately due to more cars on lease. 2023 year-to-date results were favorably impacted by more railcars on lease and negatively impacted by changes in foreign currency exchange rates.

At Sept. 30, 2023, GATX Rail Europe's (GRE) fleet consisted of over 29,100 cars. Utilization was 96.0%, compared to 96.9% at the end of the prior quarter and 99.4% at the end of the third quarter of 2022. Additional fleet statistics for GRE and Rail India are provided in the attached Supplemental Information under Rail Europe and Rail India Statistics.

PORTFOLIO MANAGEMENT

Portfolio Management reported segment profit of $20.2 million in the third quarter of 2023, compared to $11.2 million in the third quarter of 2022. Year-to-date 2023, Portfolio Management reported segment profit of $75.1 million, compared to a segment loss of $8.4 million for the same period of 2022. 2023 and 2022 year-to-date results include net negative impacts of $1.4 million and $46.8 million, respectively, from Tax Adjustments and Other Items. Additional details are provided in the attached Supplemental Information under Impact of Tax Adjustments and Other Items.

Excluding these impacts, higher 2023 third-quarter and year-to-date results were driven by increased earnings from the Rolls-Royce and Partners Finance (RRPF) affiliates and GATX Engine Leasing, the Company's wholly owned engine portfolio. Higher affiliate earnings from RRPF was due to improved performance across the existing engine leasing portfolio and higher remarketing income.

__________
(1)	In addition to financial results reported in accordance with GAAP, we compute certain financial measures using non-GAAP components. Specifically, we exclude the effects of certain tax adjustments and other items for purposes of presenting net income and diluted earnings per share because we believe these items are not attributable to our business operations. Management utilizes net income, excluding tax adjustments and other items, when analyzing financial performance because such amounts reflect the underlying operating results that are within management's ability to influence. Accordingly, we believe presenting this information provides investors and other users of our financial statements with meaningful supplemental information for purposes of analyzing year-to-year financial performance on a comparable basis and assessing trends.
(2)	In the second quarter of 2022, we made the decision to sell the Specialized Gas Vessels. As a result, we recorded losses in 2022 associated with the impairments of these assets. In 2023, we recorded gains and losses associated with the impairments and subsequent sales of these assets.
(3)	In the third quarter of 2022, we made the decision to exit our rail business in Russia ("Rail Russia") and recorded losses in 2022 associated with the impairment of the net assets. In the first quarter of 2023, we sold Rail Russia and recorded a gain on the final sale of this business.
(4)	Reserve recorded as part of an executed agreement for anticipated remediation costs at a previously owned property, sold in 1974.
(5)	Deferred income tax adjustment due to an enacted corporate income tax rate reduction in Austria in 2022.
(6)	Impairment losses related to aircraft spare engines in Russia that RRPF does not expect to recover.

_________
(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 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.
	In the second quarter of 2023, we modified the methodology of the LPI calculation to more consistently reflect actual trends in renewal lease rates and renewal lease terms across the North American non-boxcar fleet. We believe this modification will provide investors and other constituents with a more complete representation of lease rate and term performance. The prior period LPI metrics presented above have been updated to reflect the change in calculation. For further details, please see the GATX press release dated July 6, 2023.
(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).
(7)	Not available, not published as of the date of this release.
