FORWARD-LOOKING STATEMENTS

Statements in this report not based on historical facts are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995 and, accordingly, involve known and unknown risks and uncertainties that are difficult to predict and could cause our actual results, performance, or achievements to differ materially from those discussed. Forward-looking statements include statements as to our future expectations, beliefs, plans, strategies, objectives, events, conditions, financial performance, prospects, or future events. In some cases, forward-looking statements can be identified by the use of words such as "may," "could," "expect," "intend," "plan," "seek," "anticipate," "believe," "estimate," "predict," "potential," "outlook," "continue," "likely," "will," "would," and similar words and phrases. Forward-looking statements are necessarily based on estimates and assumptions that, while considered reasonable by us and our management, are inherently uncertain. Accordingly, you should not place undue reliance on forward-looking statements, which speak only as of the date they are made, and are not guarantees of future performance. We do not undertake any obligation to publicly update or revise these forward-looking statements.

The following factors, in addition to those discussed under "Risk Factors" and elsewhere in our filings with the U.S. Securities and Exchange Commission, including our Annual Report on Form 10-K for the year ended December 31, 2023 and any subsequent reports on Form 10-Q, could cause actual results to differ materially from our current expectations expressed in forward-looking statements:


•a significant decline in customer demand for our transportation assets or services, including as a result of: ◦prolonged inflation or deflation ◦high interest rates ◦weak macroeconomic conditions and world trade policies ◦weak market conditions in our customers' businesses ◦adverse changes in the price of, or demand for, commodities ◦changes in railroad operations, efficiency, pricing and service offerings, including those related to "precision scheduled railroading" or labor strikes or shortages ◦changes in, or disruptions to, supply chains ◦availability of pipelines, trucks, and other alternative modes of transportation ◦changes in conditions affecting the aviation industry, including global conflicts, geographic exposure and customer concentrations ◦customers' desire to buy, rather than lease, our transportation assets ◦other operational or commercial needs or decisions of our customers •inability to maintain our transportation assets on lease at satisfactory rates due to oversupply of assets in the market or other changes in supply and demand •competitive factors in our primary markets, including competitors with significantly lower costs of capital •higher costs associated with increased assignments of our transportation assets following non-renewal of leases, customer defaults, and compliance maintenance programs or other maintenance initiatives •events having an adverse impact on assets, customers, or regions where we have a concentrated investment exposure •financial and operational risks associated with long-term purchase commitments for transportation assets •reduced opportunities to generate asset remarketing income •inability to successfully consummate and manage ongoing acquisition and divestiture activities •reliance on Rolls-Royce in connection with our aircraft spare engine leasing businesses, and the risks that certain factors that adversely affect Rolls-Royce could have an adverse effect on our businesses •potential obsolescence of our assets						•risks related to our international operations and expansion into new geographic markets, including laws, regulations, tariffs, taxes, treaties or trade barriers affecting our activities in the countries where we do business •failure to successfully negotiate collective bargaining agreements with the unions representing a substantial portion of our employees •inability to attract, retain, and motivate qualified personnel, including key management personnel •inability to maintain and secure our information technology infrastructure from cybersecurity threats and related disruption of our business •exposure to damages, fines, criminal and civil penalties, and reputational harm arising from a negative outcome in litigation, including claims arising from an accident involving transportation assets •changes in, or failure to comply with, laws, rules, and regulations •environmental liabilities and remediation costs •operational, functional and regulatory risks associated with climate change, severe weather events and natural disasters, and other environmental, social and governance matters •U.S. and global political conditions and the impact of increased geopolitical tension and wars, including the ongoing war between Russia and Ukraine and resulting sanctions and countermeasures, on domestic and global economic conditions in general, including supply chain challenges and disruptions •prolonged inflation or deflation •fluctuations in foreign exchange rates •deterioration of conditions in the capital markets, reductions in our credit ratings, or increases in our financing costs •the emergence of new variants of COVID-19 or the occurrence of another widespread health crisis and the impact of measures taken in response •inability to obtain cost-effective insurance •changes in assumptions, increases in funding requirements or investment losses in our pension and post-retirement plans •inadequate allowances to cover credit losses in our portfolio •asset impairment charges we may be required to recognize •inability to maintain effective internal control over financial reporting and disclosure controls and procedures

GATX CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

NOTE 1. Description of Business

As used herein, "GATX," "we," "us," "our," and similar terms refer to GATX Corporation and its subsidiaries, unless indicated otherwise.

We lease, operate, manage, and remarket long-lived, widely used assets, primarily in the rail market. We report our financial results through three primary business segments: Rail North America, Rail International, and Engine Leasing (previously named Portfolio Management). Financial results for our tank container leasing business ("Trifleet") are reported in the Other segment.

In the first quarter of 2024, we changed the name of our Portfolio Management business segment to Engine Leasing to reflect the prospective operations of this business segment. Historically, this business segment included marine operations from our liquefied gas-carrying vessels (the "Specialized Gas Vessels"). As of December 31, 2023, we had sold all of our marine assets and no longer have any marine operations. The segment is now almost entirely composed of our engine leasing operations, which include our ownership interest in the RRPF affiliates, a group of joint ventures with Rolls-Royce plc (or affiliates thereof, collectively "Rolls-Royce") that lease aircraft spare engines, and GATX Engine Leasing ("GEL"), our business that directly owns aircraft spare engines that are leased to airline customers or employed in an engine capacity agreement.

NOTE 2. Basis of Presentation

We prepared the accompanying unaudited condensed consolidated financial statements in accordance with U.S. Generally Accepted Accounting Principles ("GAAP") for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, our unaudited condensed consolidated financial statements do not include all of the information and footnotes required for complete financial statements. We have included all of the normal recurring adjustments that we deemed necessary for a fair presentation.

Operating results for the nine months ended September 30, 2024 are not necessarily indicative of the results we may achieve for the entire year ending December 31, 2024. In particular, asset remarketing income does not occur evenly throughout the year. For more information, refer to the consolidated financial statements and footnotes in our Annual Report on Form 10-K for the year ended December 31, 2023.

New Accounting Pronouncements Not Yet Adopted


Standard/Description	Effective Date and Adoption Considerations	Effect on Financial Statements or Other Significant Matters
Segment Reporting In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, to improve reportable segment disclosure requirements, particularly around the disclosure of segment expenses that are regularly reported to the chief operating decision maker ("CODM") and included within each reported measure of segment profit.	The new guidance is effective for us beginning with our 2024 Form 10-K, with early adoption permitted. We plan to adopt this standard for our 2024 Form 10-K.	We have completed a preliminary assessment and do not anticipate any significant changes in our existing segment disclosures upon adoption.
Income Taxes In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to enhance disclosures for the effective rate reconciliation and income taxes paid.	The new guidance is effective for us beginning with our 2025 Form 10-K, with early adoption permitted.	We continue to assess the effect the new guidance will have on our disclosures. We expect the primary impact to be the level of disaggregation disclosed in the effective rate reconciliation table and the addition of income taxes paid by jurisdiction.

NOTE 3. Revenue

Revenue Recognition

Revenue is recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services.

We disaggregate revenue into four categories as presented on our statement of comprehensive income:

Lease Revenue

Lease revenue, which includes operating lease revenue and finance lease revenue, is our primary source of revenue.

Operating Lease Revenue

We lease railcars, locomotives, aircraft spare engines, and tank containers under full-service and net operating leases. We price full-service leases as an integrated service that includes amounts related to maintenance, insurance, and ad valorem taxes. We do not offer stand-alone maintenance service contracts. Operating lease revenue is within the scope of Accounting Standards Codification ("ASC") Topic 842 "Leases" ("Topic 842"), and we have elected not to separate non-lease components from the associated lease component for qualifying leases. Operating lease revenue is recognized on a straight-line basis over the term of the underlying lease. As a result, lease revenue may not be recognized in the same period as maintenance and other costs, which we expense as incurred. Variable rents are recognized when applicable contingencies are resolved. Revenue is not recognized if collectability is not reasonably assured. See "Note 5. Leases".

Finance Lease Revenue

In certain cases, we lease railcars and tank containers that, at lease inception, are classified as finance leases. In accordance with Topic 842, finance lease revenue is recognized using the effective interest method, using the interest rate implicit in the lease. See "Note 5. Leases".

Non-Dedicated Engine Revenue

Certain of our owned aircraft spare engines are part of a pool of non-dedicated spare engines managed under a capacity agreement with Rolls-Royce. Revenue is earned based on our continued ability to meet engine capacity requirements under the agreement, which requires us to enroll a minimum number of engines in a pool of non-dedicated spare engines for short-term lease to Rolls-Royce customers. We recognize revenue based on our right to receive a portion of the revenue earned by the pool, which is calculated based on the average engine flight hours reported for each type of engine enrolled into the pool.

Marine Operating Revenue

Historically, we generated marine operating revenue through shipping services completed by our marine vessels. For vessels that operated in a pooling arrangement, we recognized pool revenue based on the right to receive our portion of net distributions reported by the pool, with net distributions being the net voyage revenue of the pool after deduction of voyage expenses. For vessels that operated outside of a pooling arrangement, we recognized revenue over time as the performance obligation is satisfied, beginning when cargo is loaded through its delivery and discharge. As of the first quarter of 2024, we no longer have marine operating revenue, as all marine vessels were sold as of December 31, 2023.

Other Revenue

Other revenue is composed of customer liability repair revenue, termination fees, interest income, and other miscellaneous revenues. Select components of other revenue are within the scope of ASC Topic 606, "Revenue from Contracts with Customers". Revenue attributable to terms provided in our lease contracts are variable lease components that are recognized when earned, in accordance with Topic 842.

NOTE 4. Operating Assets and Facilities

The following table shows the components of our operating assets and facilities (in millions):

Total depreciation expense was $108.0 million and $311.5 million for the three and nine months ended September 30, 2024 and $100.0 million and $289.4 million for the three and nine months ended September 30, 2023.

NOTE 5. Leases

GATX as Lessor

We lease railcars, locomotives, aircraft spare engines, and tank containers under full-service and net operating leases. We price full-service leases as an integrated service that includes amounts related to maintenance, insurance, and ad valorem taxes. In accordance with applicable guidance, we do not separate lease and non-lease components when reporting revenue for our full-service operating leases. In some cases, we lease railcars and tank containers that, at commencement, are classified as finance leases. For certain operating leases, revenue is based on equipment usage and is recognized when earned. Typically, our leases do not provide customers with renewal options or options to purchase the asset. Our lease agreements do not generally have residual value guarantees. We collect reimbursements from customers for damage to our railcars, as well as additional rental payments for usage above specified levels, as provided in the lease agreements.

The following table shows the components of our lease revenue (in millions):


	Three Months Ended September 30				Nine Months Ended September 30
	2024		2023		2024		2023
Operating lease revenue:

NOTE 6. Fair Value

The assets and liabilities that GATX records at fair value on a recurring basis consisted entirely of derivatives at September 30, 2024 and December 31, 2023.

In addition, we review long-lived assets, such as operating assets and facilities, investments in affiliates, and goodwill, for impairment whenever circumstances indicate that the carrying amount of these assets may not be recoverable or when assets may be classified as held for sale. We determine the fair value of the respective assets using Level 3 inputs, including estimates of discounted future cash flows, independent appraisals, and market comparables, as applicable.

Derivative Instruments

Fair Value Hedges

We use interest rate swaps to manage the fixed-to-floating rate mix of our debt obligations by converting a portion of our fixed rate debt to floating rate debt. For fair value hedges, we recognize changes in fair value of both the derivative and the hedged item as interest expense. We had four instruments outstanding with an aggregate notional amount of $200.0 million as of September 30, 2024 with maturities ranging from 2025 to 2027 and four instruments outstanding with an aggregate notional amount of $200.0 million as of December 31, 2023 with maturities ranging from 2025 to 2027.

Cash Flow Hedges

We use Treasury rate locks and swap rate locks to hedge our exposure to interest rate risk on anticipated transactions. We also use currency swaps, forwards, and put/call options to hedge our exposure to fluctuations in the exchange rates of foreign currencies for certain loans and operating expenses denominated in non-functional currencies. We had three instruments outstanding with a notional amount of $6.6 million as of September 30, 2024 that mature in 2024 and one instrument outstanding with a notional amount of $131.0 million as of December 31, 2023 that matured in 2024. Within the next 12 months, we expect to reclassify $1.2 million ($0.9 million after-tax) of net losses on previously terminated derivatives from accumulated other comprehensive loss to interest expense. We reclassify these amounts when interest and operating lease expense on the related hedged transactions affect earnings.

Non-Designated Derivatives

We do not hold derivative financial instruments for purposes other than hedging, although certain of our derivatives are not designated as accounting hedges. We recognize changes in the fair value of these derivatives in other expense immediately.

Certain of our derivative instruments contain credit risk provisions that could require us to make immediate payment on net liability positions in the event that we default on certain outstanding debt obligations. The aggregate fair value of our derivative instruments with credit risk related contingent features that were in a liability position was $4.3 million as of September 30, 2024 and $8.0 million as of December 31, 2023. We are not required to post any collateral on our derivative instruments and do not expect the credit risk provisions to be triggered.

In the event that a counterparty fails to meet the terms of an interest rate swap agreement or a foreign exchange contract, our exposure is limited to the fair value of the swap, if in our favor. We manage the credit risk of counterparties by transacting with institutions that we consider financially sound and by avoiding concentrations of risk with a single counterparty. We believe that the risk of non-performance by any of our counterparties is remote.

Other Financial Instruments

Except for derivatives, as disclosed above, GATX has no other assets and liabilities measured at fair value on a recurring basis. The carrying amounts of cash and cash equivalents, restricted cash, rent and other receivables, accounts payable, and commercial paper and borrowings under bank credit facilities with maturities under one year approximate fair value due to the short maturity of those instruments.

We estimate the fair values of fixed and floating rate debt using discounted cash flow analyses that are based on interest rates currently offered for loans with similar terms to borrowers of similar credit quality. The inputs we use to estimate each of these values are classified in Level 2 of the fair value hierarchy because they are directly or indirectly observable inputs.

NOTE 8. Share-Based Compensation

During the nine months ended September 30, 2024, we granted 194,100 non-qualified employee stock options, 32,114 restricted stock units, 38,940 performance shares, and 12,712 restricted stock units awarded to non-employee directors. For the three and nine months ended September 30, 2024, total share-based compensation expense was $4.8 million and $15.6 million and the related tax benefits were $1.2 million and $3.7 million. For the three and nine months ended September 30, 2023, total share-based compensation expense was $2.8 million and $11.4 million and the related tax benefits were $0.7 million and $2.9 million.

The estimated fair value of our 2024 non-qualified employee stock option awards and related underlying assumptions are shown in the table below:


	2024
Weighted-average estimated fair value	$	45.22
Quarterly dividend rate	$	0.58
Expected term of stock options, in years	4.2
Risk-free interest rate	4.0		%
Dividend yield	1.8		%
Expected stock price volatility	34.7		%
Present value of dividends	$	8.87

NOTE 9. Income Taxes

The following table shows our effective income tax rate for the nine months ended September 30:


	2024		2023
Effective income tax rate	25.8	%	26.5	%

The decrease in the effective rate for the current year compared to the prior year was primarily due to an increase in the incremental benefits associated with equity awards vested or exercised during the current year, a release of a Canadian tax reserve, as well as the mix of pre-tax income among domestic and foreign jurisdictions, which are taxed at different rates.

NOTE 10. Commercial Commitments

We have entered into various commercial commitments, including standby letters of credit and performance bonds. These commercial commitments require us to fulfill specific obligations in the event of third-party demands. Similar to our balance sheet investments, these commitments expose us to credit, market, and equipment risk. Accordingly, we evaluate these commitments and other contingent obligations using techniques similar to those we use to evaluate funded transactions.

The following table shows our commercial commitments (in millions):


	September 30 2024		December 31 2023
Standby letters of credit and performance bonds	$	8.7	$	8.7
Total commercial commitments (1)	$	8.7	$	8.7

_________

(1) There were no liabilities recorded on the balance sheet for commercial commitments at September 30, 2024 and December 31, 2023. As of September 30, 2024, our outstanding commitments expire in 2024 through 2026. We are not aware of any event that would require us to satisfy any of our commitments.

We are parties to standby letters of credit and performance bonds, which primarily relate to contractual obligations and general liability insurance coverages. No material claims have been made against these obligations, and no material losses are anticipated.

NOTE 11. Earnings per Share

We compute basic and diluted earnings per share using the two-class method, which is an earnings allocation calculation that determines Earnings Per Share ("EPS") for each class of common stock and participating security. Our vested and exercisable stock options contain non-forfeitable rights to dividends or dividend equivalents and are classified as participating securities in the calculation of EPS. Our unvested stock options, restricted stock units, performance shares and non-employee director awards do not contain nonforfeitable rights to dividends or dividend equivalents and are therefore not classified as participating securities.

NOTE 13. Legal Proceedings and Other Contingencies

Various legal actions, claims, assessments and other contingencies arising in the ordinary course of business are pending against GATX and certain of our subsidiaries. These matters are subject to many uncertainties, and it is possible that some of these matters could ultimately be decided, resolved or settled adversely.

On June 30, 2023, a third-party complaint was filed by Norfolk Southern Railway Company and Norfolk Southern Corporation (collectively, “Norfolk Southern”) against GATX and several other parties in the Northern District of Ohio (Eastern Division) for contribution and recovery of environmental damages related to the derailment of a Norfolk Southern train in East Palestine, Ohio that included railcars owned by GATX Corporation. The Company filed a motion to dismiss Norfolk Southern's third-party complaint on September 15, 2023. On March 6, 2024, the Court granted GATX's and the other third-party defendants’ motions and dismissed all Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA") claims. The Court also dismissed all state law claims, declining to exercise supplemental jurisdiction over them in light of its dismissal of the CERCLA claims. On March 26, 2024, Norfolk Southern moved the Court for entry of partial final judgment as to the order dismissing the third-party complaint in order to appeal before final judgment the Court’s dismissal order as to GATX and the other third-party defendants. The Court has not yet ruled on Norfolk Southern’s motion. In the interim, on May 23, 2024, Norfolk Southern entered into a Consent Decree settling claims with the United States Department of Justice and Environmental Protection Agency (but not the State of Ohio) to which GATX is not a party.

GATX CORPORATION AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) (Continued)

On July 25, 2023, a separate third-party complaint was filed by Norfolk Southern against GATX and two other defendants in the Northern District of Ohio (Eastern Division) for contribution to personal injury and property damages class claims related to the derailment of the Norfolk Southern train in East Palestine, Ohio. The plaintiffs who had originally filed the complaint against Norfolk Southern ("Plaintiffs") themselves subsequently filed direct claims against GATX and the two other third-party defendants alleging many of the same facts as Norfolk Southern. On September 15, 2023, the Company filed a motion to dismiss Norfolk Southern's third-party complaint, and on September 26, 2023, filed a motion to dismiss the Plaintiffs' complaint. Briefing was completed on October 30, 2023, and the Court issued an order on March 13, 2024, denying in part, and granting in part, the Company’s motion against Norfolk Southern and Plaintiffs. The Court held that Norfolk Southern’s contribution action was premature and dismissed the claim without prejudice but otherwise allowed the remaining claims against GATX to proceed. The Court also dismissed Plaintiffs’ claim for medical monitoring but held that Plaintiffs could seek such damages through their other claims, which could proceed. The Court also consolidated an additional action filed against GATX and others titled Almasy, et al. v. Norfolk Southern Corp., et al. by over 40 individual residents, employees and property owners in East Palestine, Ohio. Plaintiffs and Norfolk Southern reached a settlement for $600 million to resolve the consolidated class action claims of those within a 20-mile radius from the derailment, and, for those residents who choose to participate, personal injury claims within a 10-mile radius from the derailment. On September 25, 2024, the Court held a final approval hearing and two days later issued its final approval order for the settlement. To date, a handful of appeals challenging the fairness, reasonableness and adequacy of the settlement have been filed with the Sixth Circuit Court of Appeals. On October 9, 2024, all parties to the litigation filed motions for summary judgment for the pending claims. Norfolk Southern has requested leave to reinstate its contribution claims against GATX and others. Trial is currently scheduled for March 31, 2025.

On December 8, 2023, GATX and three other defendants were named as additional defendants in a putative class action lawsuit originally filed in federal court in Pennsylvania against Norfolk Southern by four Pennsylvania school districts and their students. The allegations largely mirror those in the action filed in federal court in Ohio. The amended complaint seeks monetary damages for the Pennsylvania plaintiffs for personal injury and property damage allegedly related to the derailment. The Company and other defendants filed a motion to dismiss on February 23, 2024. Briefing has been completed and the motions remain pending and undecided. The Court has not set any further deadlines.

The Company is vigorously defending itself against each of these lawsuits. At this time, the Company cannot reasonably estimate the loss or range of loss, if any, that may ultimately be incurred in connection with any of these lawsuits and has not established any accruals for potential liability related to this incident.

For a full discussion of our other pending legal matters, please refer to "Note 23. Legal Proceedings and Other Contingencies" in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2023.

NOTE 14. Financial Data of Business Segments

The financial data presented below depicts the profitability, financial position, and capital expenditures of each of our business segments.

Rail North America is composed of our operations in the United States, Canada, and Mexico. Rail North America primarily provides railcars pursuant to full-service leases under which it maintains the railcars, pays ad valorem taxes and insurance, and provides other ancillary services.

Rail International is composed of our operations in Europe ("GATX Rail Europe" or "GRE"), India ("Rail India"), and until January 31, 2023, our rail business in Russia ("Rail Russia"). On January 31, 2023, we completed the sale of Rail Russia and recorded a gain of $0.3 million, which is presented in net gain on asset dispositions in the statements of comprehensive income. GRE primarily leases railcars to customers throughout Europe pursuant to full-service leases under which it maintains the railcars and provides value-added services according to customer requirements. Rail India primarily leases railcars to customers in India pursuant to net leases, under which the lessee assumes responsibility for maintenance of the railcars.

As previously disclosed, in the first quarter of 2024, we changed the name of our Portfolio Management business segment to Engine Leasing to reflect the prospective operations of the segment. Historically, this business segment included marine operations from our Specialized Gas Vessels. As of December 31, 2023, we had sold all of our marine assets and no longer have any marine operations.

Engine Leasing is now almost entirely composed of our engine leasing operations, which include our ownership interest in the RRPF affiliates, a group of joint ventures with Rolls-Royce that lease aircraft spare engines, and GEL, our business that directly owns aircraft spare engines that are leased to airline customers or employed in engine capacity agreements. The RRPF affiliates manage all of GEL's aircraft spare engines, for which we paid them a fee of $1.1 million and $2.9 million for the three and nine months ended September 30, 2024 and $0.9 million and $1.9 million for the three and nine months ended September 30, 2023.

Other includes Trifleet operations, as well as selling, general and administrative expenses, income taxes, and certain other amounts not allocated to the segments.

Segment profit is an internal performance measure used by the Chief Executive Officer to assess the profitability of each segment. Segment profit includes all revenues, expenses, pre-tax earnings from affiliates, and net gains on asset dispositions that are directly attributable to each segment. We allocate interest expense to the segments based on what we believe to be the appropriate risk-adjusted borrowing costs for each segment. Segment profit excludes selling, general and administrative expenses, income taxes, and certain other amounts not allocated to the segments.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes and other information included elsewhere in this Quarterly Report, Annual Report on Form 10-K for the year ended December 31, 2023, and in our other filings with the Securities and Exchange Commission ("SEC"). We based the discussion and analysis that follows on financial data we derived from the financial statements prepared in accordance with U.S. Generally Accepted Accounting Standards ("GAAP") and on certain other financial data that we prepared using non-GAAP components. For a reconciliation of these non-GAAP components to the most comparable GAAP components, see "Non-GAAP Financial Measures" at the end of this item. The discussion and analysis below includes forward-looking statements that are subject to risks, uncertainties and other factors described in the "Risk Factors" section of our Annual Report on Form 10-K for the year ended December 31, 2023 that could cause actual results to differ materially from such forward-looking statements. Additionally, our historical results are not necessarily indicative of the results that may be expected for any period in the future.

OVERVIEW

DISCUSSION OF OPERATING RESULTS

Net income for the nine months ended September 30, 2024 was $207.7 million, or $5.68 per diluted share, compared to $193.2 million, or $5.30 per diluted share, for the same period in 2023. Results for the nine months ended September 30, 2024 included a net negative impact of $9.9 million ($0.27 per diluted share) from tax adjustments and other items, compared to a net negative impact of $1.1 million ($0.03 per diluted share) from tax adjustments and other items for the nine months ended September 30, 2023. See "Non-GAAP Financial Measures" at the end of this item for further details. Excluding the impact of these items, net income increased $23.3 million compared to the prior year, largely due to higher revenue at Rail North America and Rail International, higher non-dedicated engine revenue at Engine Leasing, higher asset disposition gains at Rail North America, and higher share of affiliates' earnings at the RRPF affiliates, partially offset by higher maintenance and interest expense and the absence of the sale of natural gas holdings in the prior year.

Net income for the three months ended September 30, 2024 was $89.0 million, or $2.43 per diluted share, compared to $52.5 million, or $1.44 per diluted share, for the same period in 2023. Results for the three months ended September 30, 2024 included a net negative impact of $2.5 million ($0.07 per diluted share) from tax adjustments and other items. See "Non-GAAP Financial Measures" at the end of this item for further details. Excluding the impact of these items, net income increased $39.0 million compared to the prior year, largely due to higher revenue at Rail North America and Rail International, higher non-dedicated engine revenue at Engine Leasing, higher asset disposition gains at Rail North America, and higher share of affiliates' earnings at the RRPF affiliates, partially offset by higher maintenance and interest expense and the absence of the sale of natural gas holdings in the prior year.

Rail North America Fleet Data

The following table shows fleet activity and statistics for Rail North America railcars, excluding boxcars, for the quarter ended:


	September 30 2023		December 31 2023		March 31 2024		June 30 2024		September 30 2024

Average active railcars (4)	99,796		100,197		100,677		101,181		101,629

_________

(1) Utilization is calculated as the number of railcars on lease as a percentage of total railcars in the fleet.

(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) Active railcars refers to the number of railcars on lease to customers. Changes in railcars on lease compared to prior quarters are impacted by the utilization of new railcars purchased from builders or in the secondary market and the disposition of railcars that were sold or scrapped, as well as the fleet utilization rate.

(4) Average active railcars for the quarter is calculated using the number of active railcars at the end of each month.

As of September 30, 2024, leases for approximately 7,200 tank and freight cars and approximately 1,000 boxcars were scheduled to expire over the remainder of 2024. These amounts exclude railcars on leases expiring in 2024 that have already been renewed or assigned to a new lessee.

In 2022, we entered into a new long-term railcar supply agreement with a subsidiary of Trinity Industries, Inc. ("Trinity") to purchase 15,000 newly built railcars through 2028, with an option to order up to an additional 500 railcars each year from 2023 to 2028. The agreement enables us to order a broad mix of tank and freight cars. Trinity will deliver 6,000 tank cars (1,200 per year) from 2024 through 2028. The remaining 9,000 railcars, which can be a mix of freight and tank cars, are expected to be ordered at a rate of 1,500 railcars per order year from 2023 to 2028 and delivered under a schedule to be determined. At September 30, 2024, 5,014 railcars have been ordered pursuant to the terms of the agreement, of which 2,833 railcars have been delivered.

In 2018, we amended a long-term supply agreement with Trinity to extend the term to December 2023, and we agreed to purchase 4,800 tank cars (1,200 per year) beginning in January 2020 and continuing through 2023. As of June 30, 2024, all 4,800 railcars have been ordered and delivered.

In 2018, we entered into a multi-year railcar supply agreement with American Railcar Industries, Inc. ("ARI"), pursuant to which we agreed to purchase 7,650 newly built railcars. The order encompasses a mix of tank and freight cars to be delivered over a five-year period, beginning in April 2019 and ending in December 2023. ARI's railcar manufacturing business was acquired by a subsidiary of The Greenbrier Companies, Inc. on July 26, 2019, and such subsidiary assumed all of ARI's obligations under our long-term supply agreement. As of June 30, 2024, all 7,650 railcars have been ordered and delivered.

Lease Price Index

Our 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.

During the third quarter of 2024, the renewal rate change of the LPI was positive 26.6%, compared to positive 29.4% in the prior quarter, and positive 33.4% in the third quarter of 2023. Lease terms on renewals for railcars in the LPI averaged 59 months in the current quarter, compared to 61 months in the prior quarter, and 65 months in the third quarter of 2023.

The following table shows fleet activity and statistics for Rail North America boxcars for the quarter ended:


	September 30 2023		December 31 2023		March 31 2024		June 30 2024		September 30 2024

Average active railcars (3)	8,985		9,207		9,583		9,304		8,848

_________

(1) Utilization is calculated as the number of boxcars on lease as a percentage of total boxcars in the fleet.

(2) Active boxcars refers to the number boxcars on lease to customers. Changes in boxcars on lease compared to prior quarters are impacted by the utilization of new boxcars purchased from builders or in the secondary market and the disposition of boxcars that were sold or scrapped, as well as the fleet utilization rate.

(3) Average active boxcars is calculated using the number of active boxcars at the end of each month.

Comparison of Reported Results for the First Nine Months of 2024 to the First Nine Months of 2023

Segment Profit

In the nine months ended September 30, 2024, segment profit of $271.5 million increased 12.8% compared to $240.6 million for the same period in the prior year. The increase was primarily due to higher lease revenue and higher net gain on asset dispositions, partially offset by higher interest expense and higher maintenance expense. The amount and timing of disposition gains is dependent on a number of factors and may vary materially from period to period.

Revenues

In the nine months ended September 30, 2024, lease revenue increased $68.6 million, or 10.4%, driven by higher lease rates and more railcars on lease. Other revenue increased $18.1 million, primarily due to higher repair revenue.

Expenses

In the nine months ended September 30, 2024, maintenance expense increased $24.9 million, driven by higher costs of repairs, more regulatory compliance events, and more repairs performed by the railroads. Depreciation expense increased $2.6 million, due to the timing of new railcar investments and dispositions, partially offset by a change in the useful lives of certain railcars.

Other Income (Expense)

In the nine months ended September 30, 2024, net gain on asset dispositions increased $8.4 million, driven by higher net gains on railcars sold and higher net scrapping gains. The amount and timing of disposition gains is dependent on a number of factors and may vary materially from period to period. Net interest expense increased $36.5 million, due to a higher average interest rate and a higher average debt balance.

Investment Volume

During the nine months ended September 30, 2024, investment volume was $955.7 million compared to $654.8 million in the same period in 2023. We acquired 2,987 newly built railcars, purchased 2,005 railcars in the secondary market, and purchased 156 locomotives in the secondary market in the nine months ended September 30, 2024, compared to 2,506 newly built railcars, 1,266 railcars in the secondary market, and no locomotives in the same period in 2023.

Our investment volume is predominantly composed of acquired railcars, but also includes certain capitalized repairs and improvements to owned railcars and our maintenance facilities. As a result, the dollar value of investment volume does not necessarily correspond to the number of railcars acquired in any given period. In addition, the comparability of amounts invested and the number of railcars acquired in each period is impacted by the mix of railcars purchased, which may include tank cars and freight cars, as well as newly manufactured railcars or those purchased in the secondary market.

Comparison of Reported Results for the Third Quarter of 2024 to the Third Quarter of 2023

Segment Profit

In the three months ended September 30, 2024, segment profit of $102.4 million increased 54.9% compared to $66.1 million for the same period in the prior year. The increase was primarily due to higher net gain on asset dispositions and higher lease revenue, partially offset by higher interest and maintenance expense. The amount and timing of disposition gains is dependent on a number of factors and may vary materially from period to period.

Revenues

In the three months ended September 30, 2024, lease revenue increased $24.0 million, or 10.7%, driven by more railcars on lease and higher lease rates. Other revenue increased $6.6 million, primarily due to higher repair revenue.

Expenses

In the three months ended September 30, 2024, maintenance expense increased $8.3 million, driven by more repair events, including more repairs performed by the railroads, and higher costs of repairs. Depreciation expense increased $2.3 million, due to the timing of new railcar investments and dispositions, partially offset by a change in the useful lives of certain railcars.

Other Income (Expense)

In the three months ended September 30, 2024, net gain on asset dispositions increased $31.2 million, driven by higher net gains on railcars sold in the current year and higher net scrapping gains. The amount and timing of disposition gains is dependent on a number of factors and may vary materially from period to period. Net interest expense increased $13.6 million, due to a higher average debt balance and higher average interest rate.

RAIL INTERNATIONAL

Segment Summary

Rail International, composed primarily of GATX Rail Europe ("GRE"), produced solid operating results in the nine months of 2024 and continued to grow its fleet. GRE experienced renewal lease rate increases for a majority of railcar types in the period. Utilization was 95.9% at the end of the current quarter.

The fleet size of our rail business in India ("Rail India") surpassed 10,000 railcars during the current quarter, and Rail India continued to focus on investment opportunities, diversification of its fleet, and developing relationships with customers, suppliers and the Indian Railways. Demand for railcars in India remained robust, driven by continued growth in the economy and infrastructure development. Utilization was 100.0% at the end of the current quarter.

In the first quarter of 2023, we sold Rail Russia and recorded a gain of $0.3 million upon completion of the sale.

Comparison of Reported Results for the First Nine Months of 2024 to the First Nine Months of 2023

Foreign Currency

Rail International's reported results of operations are impacted by fluctuations in the exchange rates of the U.S. dollar against the foreign currencies in which it conducts business, primarily the euro. In the nine months ended September 30, 2024, fluctuations in the value of the euro, relative to the U.S. dollar, positively impacted lease revenue by approximately $1.1 million and negatively impacted segment profit, excluding other income (expense), by approximately $1.1 million compared to the same period in 2023.

Segment Profit

In the nine months ended September 30, 2024, segment profit of $89.2 million increased 12.9% compared to $79.0 million for the same period in the prior year. Segment profit in 2023 included a $0.3 million disposition gain recorded as a result of the decision to exit the Rail Russia business. Excluding this item, results for Rail International were $10.5 million higher compared to the same period in the prior year. The increase was primarily due to more railcars on lease and higher lease rates at both GRE and Rail India, partially offset by higher maintenance expense at GRE and higher interest expense.

Revenues

In the nine months ended September 30, 2024, lease revenue increased $29.8 million, or 13.6%, due to more railcars on lease and higher lease rates at GRE and Rail India and the impact of foreign exchange rates.

Expenses

In the nine months ended September 30, 2024, maintenance expense increased $5.1 million, primarily due to more repairs performed, higher costs for repairs, higher wheelset costs, and the impact of foreign exchange rates. Depreciation expense increased $8.8 million, due the impact of new railcars added to the fleet.

Other Income (Expense)

In the nine months ended September 30, 2024, net gain on asset dispositions increased $1.3 million, driven by more railcars sold and higher net scrapping gains due to more railcars scrapped at a higher scrap price per ton. Net interest expense increased $12.2 million, due to a higher average debt balance and a higher average interest rate. Other income (expense) was favorable by $7.8 million, driven by the positive impact of changes in foreign exchange rates, primarily euro-zloty fluctuations.

Investment Volume

During the nine months ended September 30, 2024, investment volume was $190.1 million compared to $288.0 million in the same period in 2023. In the nine months ended September 30, 2024, GRE acquired 1,120 newly built railcars compared to 1,324 newly built railcars for the same period in 2023, and Rail India acquired 1,561 newly built railcars in the current year compared to 2,012 newly built railcars for the same period in 2023.

Our investment volume is predominantly composed of acquired railcars, but also includes certain capitalized repairs and improvements to owned railcars. As a result, the dollar value of investment volume does not necessarily correspond to the number of railcars acquired in any given period. In addition, the comparability of amounts invested and the number of railcars acquired in each period is impacted by the mix of the various car types acquired, as well as fluctuations in the exchange rates of the foreign currencies in which Rail International conducts business.

Comparison of Reported Results for the Third Quarter of 2024 to the Third Quarter of 2023

Foreign Currency

Rail International's reported results of operations are impacted by fluctuations in the exchange rates of the U.S. dollar against the foreign currencies in which it conducts business, primarily the euro. In the three months ended September 30, 2024, fluctuations in the value of the euro, relative to the U.S. dollar, positively impacted lease revenue by approximately $0.8 million and had an immaterial impact on segment profit, excluding other income (expense), compared to the same period in 2023.

Segment Profit

In the three months ended September 30, 2024, segment profit of $33.9 million increased 20.2% compared to $28.2 million for the same period in the prior year. The increase was primarily due to more railcars on lease and higher lease rates at both GRE and Rail India, partially offset by higher interest and depreciation expense.

Revenues

In the three months ended September 30, 2024, lease revenue increased $10.7 million, or 14.2%, due to more railcars on lease and higher lease rates at GRE and Rail India and the impact of foreign exchange rates.

Expenses

In the three months ended September 30, 2024, maintenance expense was comparable to the same period in the prior year, as lower wheelset costs were offset by higher costs for repairs and the impact of foreign exchange rates. Depreciation expense increased $2.8 million, due the impact of new railcars added to the fleet.

Other Income (Expense)

In the three months ended September 30, 2024, net gain on asset dispositions increased $0.8 million, driven by more railcars sold, offset by lower net scrapping gains due to fewer railcars scrapped at a higher scrap price per ton. Net interest expense increased $4.0 million, due to a higher average interest rate and a higher average debt balance. Other income (expense) was favorable by $1.2 million, driven by the positive impact of changes in foreign exchange rates, primarily euro-zloty fluctuations.

ENGINE LEASING

Segment Summary

As disclosed previously, we had sold all of our marine assets as of December 31, 2023 and no longer have any marine operations. As a result, we have changed the name of this business segment from Portfolio Management to Engine Leasing to reflect the prospective operations of the segment.

Engine Leasing's segment profit is attributable primarily to income from the RRPF affiliates, a group of 50% owned domestic and foreign joint ventures with Rolls-Royce, a leading manufacturer of commercial aircraft jet engines. Segment profit included earnings from the RRPF affiliates of $75.8 million and $35.2 million for the nine months and three months ended September 30, 2024, compared to $66.3 million and $18.0 million for the same periods in 2023. The operating environment for the RRPF affiliates was robust, and demand for international air passenger travel remained strong.

Engine Leasing also includes GEL, our wholly owned entity that invests directly in aircraft spare engines. GEL acquired four aircraft spare engines for $94.8 million in the third quarter of 2024. As of September 30, 2024, GEL owned 36 aircraft spare engines, with 14 on long-term leases with airline customers and 22 that are employed in an engine capacity agreement with Rolls-Royce for use in its engine maintenance programs. All engines at GEL are managed by the RRPF affiliates, for which we paid them a fee of $2.9 million and $1.1 million for the nine months and three months ended September 30, 2024 and $1.9 million and $0.9 million for the same periods in 2023.

During the second quarter of 2023, we sold our natural gas holdings and recorded a gain of $5.7 million.

Comparison of Reported Results for the First Nine Months of 2024 to the First Nine Months of 2023

Segment Profit

In the nine months ended September 30, 2024, segment profit was $81.6 million, compared to segment profit of $75.1 million for the same period in the prior year. Segment profit included $0.6 million of gains in 2024 and $1.4 million of losses in 2023 associated with the Specialized Gas Vessels. Excluding the impact of these items, results for Engine Leasing were $4.5 million higher than 2023, driven by higher earnings at the RRPF affiliates and higher earnings from GEL operations, partially offset by the absence of the gain on the sale of natural gas holdings recorded in the prior year.

Revenues

In the nine months ended September 30, 2024, lease revenue was comparable to the same period in the prior year. Non-dedicated engine revenue increased $20.5 million, due to aircraft spare engines acquired in 2023 and 2024 and utilized in the engine capacity agreement with Rolls-Royce. Marine operating revenue decreased $6.1 million, driven by the final sales of the Specialized Gas Vessels in 2023.

Expenses

In the nine months ended September 30, 2024, marine operating expense decreased $5.4 million, due to the sale of the Specialized Gas Vessels in 2023. Depreciation expense increased $7.2 million, due to aircraft spare engines acquired in 2023 and 2024.

Other Income (Expense)

In the nine months ended September 30, 2024, net gain on asset dispositions decreased $4.1 million, driven by the absence of gains recorded in 2023 for the sale of natural gas holdings and gains on the sales of the Specialized Gas Vessels in 2023 and related post-closing adjustments recorded in both 2023 and 2024.

In the nine months ended September 30, 2024, income from our share of affiliates' earnings increased $9.5 million, driven by higher income from operations, partially offset by lower remarketing income. The amount and timing of remarketing income is dependent on a number of factors and may vary materially from period to period.

Investment Volume

In the nine months ended September 30, 2024, investment volume was $166.1 million, compared to $267.3 million in the same period in 2023. In the nine months ended September 30, 2024, GEL acquired seven aircraft spare engines compared to nine in the same period in 2023.

Comparison of Reported Results for the Third Quarter of 2024 to the Third Quarter of 2023

Segment Profit

In the three months ended September 30, 2024, segment profit was $37.5 million, compared to segment profit of $20.2 million for the same period in the prior year. The increase was driven by higher earnings at the RRPF affiliates.

Revenues

In the three months ended September 30, 2024, lease revenue was comparable to the same period in the prior year. Non-dedicated engine revenue increased $4.5 million, due to aircraft spare engines acquired in 2023 and 2024 and utilized in the engine capacity agreement with Rolls-Royce. Marine operating revenue decreased $0.6 million, driven by the final sales of the Specialized Gas Vessels in 2023.

Expenses

In the three months ended September 30, 2024, marine operating expense decreased $1.0 million, due to the sale of the Specialized Gas Vessels in 2023. Depreciation expense increased $1.7 million, due to aircraft spare engines acquired in 2023 and 2024.

Other Income (Expense)

In the three months ended September 30, 2024, income from our share of affiliates' earnings increased $17.2 million, driven by higher remarketing income and higher income from operations. The amount and timing of remarketing income is dependent on a number of factors and may vary materially from period to period.

OTHER

Other comprises our Trifleet business, as well as selling, general and administrative expenses ("SG&A"), unallocated interest expense, miscellaneous income and expense not directly associated with the reporting segments, and certain eliminations.

In the third quarter of 2024, GATX recorded settlement expenses of $3.3 million for litigation claims arising out of legacy business operations. In the second quarter of 2024, GATX recorded reserves of $10.7 million for its share of anticipated environmental remediation costs arising out of prior operations and legacy businesses. The majority of the recorded reserves relate to a previously owned facility that GATX sold in 1974, while the remainder of the amount relates to a landfill that GATX entities previously utilized, which was closed in 1986.

The following table shows components of Other (in millions):

Utilization rate at quarter-end (1)	89.6	%	87.3	%	85.5	%	86.0	%	85.6	%

_________

(1) Utilization is calculated as the number of tank containers on lease as a percentage of total tank containers in the fleet.

SG&A, Unallocated Interest and Other

SG&A increased $18.3 million for the nine months ended September 30, 2024 compared to the same period in the prior year. SG&A increased $6.2 million for the three months ended September 30, 2024 compared to the same period in the prior year. Both variances were driven by higher employee-related expenses, including higher share-based compensation expense, and higher information technology expense.

Unallocated interest income (the difference between external interest expense and interest expense allocated to the reporting segments) in any year is affected by our consolidated leverage position, the timing of debt issuances and investing activities, and intercompany allocations.

Other (expense) income, including eliminations was unfavorable by $10.9 million for the nine months ended September 30, 2024 compared to the same period in the prior year. The variance was driven by environmental reserves recorded and expenses related to litigation claims settlements, as noted above, partially offset by the absence of pension settlement charges recorded in the prior year. Other (expense) income, including eliminations was unfavorable by $2.3 million in the three months ended September 30, 2024 compared to the same period in the prior year. The variance was primarily a result of expenses related to the settlements of litigation claims noted above.

Consolidated Income Taxes

See "Note 9. Income Taxes" in Part I, Item 1 of this Quarterly Report on Form 10-Q.

CASH FLOW DISCUSSION

We generate a significant amount of cash from operating activities and investment portfolio proceeds. We also access domestic and international capital markets by issuing unsecured or secured debt and commercial paper. We use these resources, along with available cash balances, to fulfill our debt, lease, and dividend obligations, to support our share repurchase programs, and to fund portfolio investments and capital additions. We primarily use cash from operations to fund daily operations. The timing of asset dispositions and changes in working capital impact cash flows from portfolio proceeds and operations. As a result, these cash flow components may vary materially from quarter to quarter and year to year.

As of September 30, 2024, we had an unrestricted cash balance of $503.7 million. We also have a $600 million, 5-year unsecured revolving credit facility in the United States that matures in 2029 and a $350 million, 3-year unsecured revolving credit facility in the United States that matures in 2027, both of which were fully available as of September 30, 2024.

The following table shows our cash flows from operating, investing and financing activities for the nine months ended September 30 (in millions):


	2024		2023
Net cash provided by operating activities	$	396.1	$	400.1
Net cash used in investing activities	(1,131.4)		(860.6)
Net cash provided by financing activities	789.1		359.9
Effect of exchange rate changes on cash, cash equivalents, and restricted cash	(0.8)		(0.2)
Net increase (decrease) in cash, cash equivalents, and restricted cash during the period	$	53.0	$	(100.8)

Net Cash Provided by Operating Activities

Net cash provided by operating activities for the nine months ended September 30, 2024 decreased $4.0 million compared to the same period in 2023. Comparability among reporting periods is impacted by the timing of changes in working capital items. Specifically, higher payments for interest, income taxes, maintenance, and other operating expenses were partially offset by higher cash receipts from revenue and lower payments for operating leases.

Net Cash Used in Investing Activities

The following table shows our principal sources and uses of cash flows from investing activities for the nine months ended September 30 (in millions):


	2024		2023
Portfolio investments and capital additions (1)	$	(1,325.1)	$	(1,237.5)
Portfolio proceeds (2)	171.7		208.2
Proceeds from short-term investments (3)	—		150.0
Other investing activity	22.0		18.7
Net cash used in investing activities	$	(1,131.4)	$	(860.6)

_________

(1) Portfolio investments and capital additions primarily consist of purchases of operating assets and capitalized asset improvements. See the discussions of segment operating results sections in this Item for more detail.

(2) Portfolio proceeds primarily consist of proceeds from sales of operating assets.

(3) Short-term U.S. Treasury Obligations with an original maturity date of over 90 days.

The increase in portfolio investments and capital additions of $87.6 million for the nine months ended September 30, 2024 was primarily due to more railcars and locomotives acquired at Rail North America, partially offset by fewer aircraft spare engines acquired at GEL, fewer railcars acquired at GRE and Rail India, and fewer tank containers acquired at Trifleet. The timing of investments depends on purchase commitments, transaction opportunities, and market conditions.

Portfolio proceeds decreased by $36.5 million for the nine months ended September 30, 2024, resulting from the absence of proceeds from the sales of two Specialized Gas Vessels at Engine Leasing and the sale of Rail Russia at Rail International in the prior year.

Net Cash Provided by Financing Activities

The following table shows our principal sources and uses of cash flows from financing activities for the nine months ended September 30 (in millions):


	2024		2023
Net proceeds from issuance of debt (original maturities longer than 90 days)	$	1,297.0	$	909.2
Repayments of debt (original maturities longer than 90 days)	(413.5)		(500.0)
Net decrease in debt with original maturities of 90 days or less	—		(5.0)
Purchases of assets previously on finance leases (1)	(30.4)		—
Dividends	(63.9)		(60.7)
Stock repurchases (2)	(21.8)		—
Other	21.7		16.4
Net cash provided by financing activities	$	789.1	$	359.9

_________

(1) In the nine months ended September 30, 2024, we purchased 728 railcars that were previously leased, compared to none during the same period in 2023.

(2) In the nine months ended September 30, 2024, we repurchased 166,400 shares of common stock for $21.8 million. We did not repurchase any shares of common stock during the same period in 2023.

LIQUIDITY AND CAPITAL RESOURCES

General

We fund our investments and meet our debt, lease, and dividend obligations using our available cash balances, as well as cash generated from operating activities, sales of assets, commercial paper issuances, committed revolving credit facilities, distributions from affiliates, and issuances of secured and unsecured debt. We primarily use cash from operations to fund daily operations. We use both domestic and international capital markets and banks to meet our debt financing needs.

Material Cash Obligations

The following table shows our material cash obligations, including debt principal and related interest payments, lease payments, and purchase commitments at September 30, 2024 (in millions):


	Material Cash Obligations by Period
	Total		2024 (1)		2025		2026		2027		2028		Thereafter
Recourse debt	$	8,351.5	$	111.4	$	657.4	$	613.1	$	848.2	$	735.3	$	5,386.1

_________

(1) For the remainder of the year.

(2) For floating rate debt, future interest payments are based on the applicable interest rate as of September 30, 2024.

(3) Primarily railcar purchase commitments. The amounts shown for all years are based on management's estimates of the timing, anticipated railcar types, and related costs of railcars to be purchased under its agreements. For additional details on our purchase agreements, refer to the discussion of Rail North America operating results within this item.

Short-Term Borrowings and Credit Lines and Facilities

We primarily use short-term borrowings as a source of working capital and to temporarily fund differences between our operating cash flows and portfolio proceeds, and our capital investments and debt maturities. We do not maintain or target any particular level of short-term borrowings on a permanent basis. Rather, we will temporarily utilize short-term borrowings at levels we deem appropriate until we decide to pay down these balances.

During the second quarter of 2024, we entered into a new $600 million, 5-year unsecured revolving credit facility in the United States, expiring in May 2029. The new credit facility contains two one-year extension options. This replaced our prior $600 million, 5-year unsecured revolving credit facility, which was terminated upon our entry into the new credit facility. As of September 30, 2024, the full $600 million was available under this facility. We also entered into a new $350 million, 3-year unsecured revolving credit facility in the United States, expiring in May 2027. This facility also has two one-year extension options. This replaced our prior $250 million 3-year unsecured revolving credit facility, which was terminated upon entry into the new credit facility. As of September 30, 2024, the full $350 million was available under this facility.

Our European subsidiaries have unsecured credit facilities with an aggregate limit of €35.0 million. As of September 30, 2024, €25.0 million was available under these credit facilities. At September 30, 2024, we had $11.1 million of outstanding short-term borrowings under bank credit facilities at our European subsidiaries. The weighted average interest rate of these outstanding borrowings during the nine months ended September 30, 2024 was 4.4%.

Delayed Draw Term Loans

As of September 30, 2024, we had INR 2.0 billion ($23.9 million) available under an outstanding delayed draw term loan in India.

Restrictive Covenants

Our $600 million and $350 million revolving credit facilities contain various restrictive covenants, including requirements to maintain a fixed charge coverage ratio and an asset coverage test. Some of our bank term loans and other loan agreements have the same financial covenants as these facilities.

The indentures for our public debt also contain various restrictive covenants, including limitations on liens provisions that restrict the amount of additional secured indebtedness that we may incur. Additionally, certain exceptions to the covenants permit us to incur an unlimited amount of purchase money and nonrecourse indebtedness.

At September 30, 2024, our European rail subsidiaries had outstanding term loans, public debt, and private placement debt balances totaling €870.0 million, and Trifleet had an outstanding term loan of €121.0 million. The loans are guaranteed by GATX Corporation and are subject to similar restrictive covenants as the revolving credit facility noted above.

At September 30, 2024, we were in compliance with all covenants and conditions of all of our credit agreements. We do not anticipate any covenant violations nor do we expect that any of these covenants will restrict our operations or our ability to obtain additional financing.

Credit Ratings

The global capital market environment and outlook may affect our funding options and our financial performance. Our access to capital markets at competitive rates depends on our credit rating and rating outlook, as determined by rating agencies.

The following table shows our credit rating and rating outlook as of September 30, 2024:

GATX Common Stock Repurchases

On January 25, 2019, our board of directors approved a $300.0 million share repurchase program, pursuant to which we are authorized to purchase shares of our common stock in the open market, in privately negotiated transactions, or otherwise, including pursuant to Rule 10b5-1 plans. The share repurchase authorization does not have an expiration date, does not obligate the Company to repurchase any dollar amount or number of shares of common stock, and may be suspended or discontinued at any time. The timing of repurchases will be dependent on market conditions and other factors. During the nine months ended September 30, 2024, we repurchased 166,400 shares of common stock for $21.8 million, excluding commissions. No share repurchases were completed during the same period in 2023. As of September 30, 2024, $65.3 million remained available under the repurchase authorization.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

There have been no changes to our critical accounting policies during the nine months ended September 30, 2024. Refer to our Annual Report on Form 10-K for the year ended December 31, 2023, for a summary of our policies.

NON-GAAP FINANCIAL MEASURES

In addition to financial results reported in accordance with GAAP, we compute certain financial measures using non-GAAP components, as defined by the SEC. These measures are not in accordance with, or a substitute for, GAAP, and our financial measures may be different from non-GAAP financial measures used by other companies. We have provided a reconciliation of our non-GAAP components to the most directly comparable GAAP components.

Reconciliation of Non-GAAP Components Used in the Computation of Certain Financial Measures

We exclude the effects of certain tax adjustments and other items for purposes of presenting net income, diluted earnings per share, and return on equity 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.

The following tables show our net income and diluted earnings per share, excluding tax adjustments and other items (in millions, except per share data):

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	Description of Business As used herein, "GATX," "we," "us," "our," and similar terms refer to GATX Corporation and its subsidiaries, unless indicated otherwise. We lease, operate, manage, and remarket long-lived, widely used assets, primarily in the rail market. We report our financial results through three primary business segments: Rail North America, Rail International, and Engine Leasing (previously named Portfolio Management). Financial results for our tank container leasing business ("Trifleet") are reported in the Other segment. In the first quarter of 2024, we changed the name of our Portfolio Management business segment to Engine Leasing to reflect the prospective operations of this business segment. Historically, this business segment included marine operations from our liquefied gas-carrying vessels (the "Specialized Gas Vessels"). As of December 31, 2023, we had sold all of our marine assets and no longer have any marine operations. The segment is now almost entirely composed of our engine leasing operations, which include our ownership interest in the RRPF affiliates, a group of joint ventures with Rolls-Royce plc (or affiliates thereof, collectively "Rolls-Royce") that lease aircraft spare engines, and GATX Engine Leasing ("GEL"), our business that directly owns aircraft spare engines that are leased to airline customers or employed in an engine capacity agreement.

Accounting Changes and Error Corrections [Abstract]

Basis of Presentation

New Accounting Pronouncements Not Yet Adopted


Standard/Description	Effective Date and Adoption Considerations	Effect on Financial Statements or Other Significant Matters
Segment Reporting In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, to improve reportable segment disclosure requirements, particularly around the disclosure of segment expenses that are regularly reported to the chief operating decision maker ("CODM") and included within each reported measure of segment profit.	The new guidance is effective for us beginning with our 2024 Form 10-K, with early adoption permitted. We plan to adopt this standard for our 2024 Form 10-K.	We have completed a preliminary assessment and do not anticipate any significant changes in our existing segment disclosures upon adoption.
Income Taxes In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to enhance disclosures for the effective rate reconciliation and income taxes paid.	The new guidance is effective for us beginning with our 2025 Form 10-K, with early adoption permitted.	We continue to assess the effect the new guidance will have on our disclosures. We expect the primary impact to be the level of disaggregation disclosed in the effective rate reconciliation table and the addition of income taxes paid by jurisdiction.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Revenue Recognition Revenue is recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. We disaggregate revenue into four categories as presented on our statement of comprehensive income: Lease Revenue Lease revenue, which includes operating lease revenue and finance lease revenue, is our primary source of revenue. Operating Lease Revenue We lease railcars, locomotives, aircraft spare engines, and tank containers under full-service and net operating leases. We price full-service leases as an integrated service that includes amounts related to maintenance, insurance, and ad valorem taxes. We do not offer stand-alone maintenance service contracts. Operating lease revenue is within the scope of Accounting Standards Codification ("ASC") Topic 842 "Leases" ("Topic 842"), and we have elected not to separate non-lease components from the associated lease component for qualifying leases. Operating lease revenue is recognized on a straight-line basis over the term of the underlying lease. As a result, lease revenue may not be recognized in the same period as maintenance and other costs, which we expense as incurred. Variable rents are recognized when applicable contingencies are resolved. Revenue is not recognized if collectability is not reasonably assured. See "Note 5. Leases". Finance Lease Revenue In certain cases, we lease railcars and tank containers that, at lease inception, are classified as finance leases. In accordance with Topic 842, finance lease revenue is recognized using the effective interest method, using the interest rate implicit in the lease. See "Note 5. Leases". Non-Dedicated Engine Revenue Certain of our owned aircraft spare engines are part of a pool of non-dedicated spare engines managed under a capacity agreement with Rolls-Royce. Revenue is earned based on our continued ability to meet engine capacity requirements under the agreement, which requires us to enroll a minimum number of engines in a pool of non-dedicated spare engines for short-term lease to Rolls-Royce customers. We recognize revenue based on our right to receive a portion of the revenue earned by the pool, which is calculated based on the average engine flight hours reported for each type of engine enrolled into the pool. Marine Operating Revenue Historically, we generated marine operating revenue through shipping services completed by our marine vessels. For vessels that operated in a pooling arrangement, we recognized pool revenue based on the right to receive our portion of net distributions reported by the pool, with net distributions being the net voyage revenue of the pool after deduction of voyage expenses. For vessels that operated outside of a pooling arrangement, we recognized revenue over time as the performance obligation is satisfied, beginning when cargo is loaded through its delivery and discharge. As of the first quarter of 2024, we no longer have marine operating revenue, as all marine vessels were sold as of December 31, 2023. Other Revenue Other revenue is composed of customer liability repair revenue, termination fees, interest income, and other miscellaneous revenues. Select components of other revenue are within the scope of ASC Topic 606, "Revenue from Contracts with Customers". Revenue attributable to terms provided in our lease contracts are variable lease components that are recognized when earned, in accordance with Topic 842.

Leases [Abstract]

Leases

GATX as Lessor

We lease railcars, locomotives, aircraft spare engines, and tank containers under full-service and net operating leases. We price full-service leases as an integrated service that includes amounts related to maintenance, insurance, and ad valorem taxes. In accordance with applicable guidance, we do not separate lease and non-lease components when reporting revenue for our full-service operating leases. In some cases, we lease railcars and tank containers that, at commencement, are classified as finance leases. For certain operating leases, revenue is based on equipment usage and is recognized when earned. Typically, our leases do not provide customers with renewal options or options to purchase the asset. Our lease agreements do not generally have residual value guarantees. We collect reimbursements from customers for damage to our railcars, as well as additional rental payments for usage above specified levels, as provided in the lease agreements.

The following table shows the components of our lease revenue (in millions):


	Three Months Ended September 30				Nine Months Ended September 30

Legal Proceedings and Other Contingencies	Sep. 30, 2024
Commitments and Contingencies Disclosure [Abstract]
Legal Proceedings and Other Contingencies	Legal Proceedings and Other Contingencies Various legal actions, claims, assessments and other contingencies arising in the ordinary course of business are pending against GATX and certain of our subsidiaries. These matters are subject to many uncertainties, and it is possible that some of these matters could ultimately be decided, resolved or settled adversely. On June 30, 2023, a third-party complaint was filed by Norfolk Southern Railway Company and Norfolk Southern Corporation (collectively, “Norfolk Southern”) against GATX and several other parties in the Northern District of Ohio (Eastern Division) for contribution and recovery of environmental damages related to the derailment of a Norfolk Southern train in East Palestine, Ohio that included railcars owned by GATX Corporation. The Company filed a motion to dismiss Norfolk Southern's third-party complaint on September 15, 2023. On March 6, 2024, the Court granted GATX's and the other third-party defendants’ motions and dismissed all Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA") claims. The Court also dismissed all state law claims, declining to exercise supplemental jurisdiction over them in light of its dismissal of the CERCLA claims. On March 26, 2024, Norfolk Southern moved the Court for entry of partial final judgment as to the order dismissing the third-party complaint in order to appeal before final judgment the Court’s dismissal order as to GATX and the other third-party defendants. The Court has not yet ruled on Norfolk Southern’s motion. In the interim, on May 23, 2024, Norfolk Southern entered into a Consent Decree settling claims with the United States Department of Justice and Environmental Protection Agency (but not the State of Ohio) to which GATX is not a party. On July 25, 2023, a separate third-party complaint was filed by Norfolk Southern against GATX and two other defendants in the Northern District of Ohio (Eastern Division) for contribution to personal injury and property damages class claims related to the derailment of the Norfolk Southern train in East Palestine, Ohio. The plaintiffs who had originally filed the complaint against Norfolk Southern ("Plaintiffs") themselves subsequently filed direct claims against GATX and the two other third-party defendants alleging many of the same facts as Norfolk Southern. On September 15, 2023, the Company filed a motion to dismiss Norfolk Southern's third-party complaint, and on September 26, 2023, filed a motion to dismiss the Plaintiffs' complaint. Briefing was completed on October 30, 2023, and the Court issued an order on March 13, 2024, denying in part, and granting in part, the Company’s motion against Norfolk Southern and Plaintiffs. The Court held that Norfolk Southern’s contribution action was premature and dismissed the claim without prejudice but otherwise allowed the remaining claims against GATX to proceed. The Court also dismissed Plaintiffs’ claim for medical monitoring but held that Plaintiffs could seek such damages through their other claims, which could proceed. The Court also consolidated an additional action filed against GATX and others titled Almasy, et al. v. Norfolk Southern Corp., et al. by over 40 individual residents, employees and property owners in East Palestine, Ohio. Plaintiffs and Norfolk Southern reached a settlement for $600 million to resolve the consolidated class action claims of those within a 20-mile radius from the derailment, and, for those residents who choose to participate, personal injury claims within a 10-mile radius from the derailment. On September 25, 2024, the Court held a final approval hearing and two days later issued its final approval order for the settlement. To date, a handful of appeals challenging the fairness, reasonableness and adequacy of the settlement have been filed with the Sixth Circuit Court of Appeals. On October 9, 2024, all parties to the litigation filed motions for summary judgment for the pending claims. Norfolk Southern has requested leave to reinstate its contribution claims against GATX and others. Trial is currently scheduled for March 31, 2025. On December 8, 2023, GATX and three other defendants were named as additional defendants in a putative class action lawsuit originally filed in federal court in Pennsylvania against Norfolk Southern by four Pennsylvania school districts and their students. The allegations largely mirror those in the action filed in federal court in Ohio. The amended complaint seeks monetary damages for the Pennsylvania plaintiffs for personal injury and property damage allegedly related to the derailment. The Company and other defendants filed a motion to dismiss on February 23, 2024. Briefing has been completed and the motions remain pending and undecided. The Court has not set any further deadlines. The Company is vigorously defending itself against each of these lawsuits. At this time, the Company cannot reasonably estimate the loss or range of loss, if any, that may ultimately be incurred in connection with any of these lawsuits and has not established any accruals for potential liability related to this incident. For a full discussion of our other pending legal matters, please refer to "Note 23. Legal Proceedings and Other Contingencies" in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2023.
