**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, except to the extent required by applicable law.

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, 2025, could cause actual results to differ materially from our current expectations expressed in forward-looking statements:

**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. Financial results for our tank container leasing business ("Trifleet") are reported in the Other segment.

On January 1, 2026, GATX acquired approximately 101,000 railcars for $4.2 billion from Wells Fargo Bank, N.A. ("Wells Fargo") through a newly formed joint venture ("GABX" or the "GABX joint venture") with Brookfield Infrastructure Partners L.P. and its institutional partners (collectively, "Brookfield"). Initially, GATX's ownership share of GABX is 30% with Brookfield's share at 70%. GATX will have the option to acquire up to 100% of GABX's equity over time. See "Note 15. Non-Controlling Interest" for further information about the options to acquire GABX's equity. The transaction was funded through a $2.96 billion term loan executed by GABX, which is guaranteed by GATX, and equity contributions of $385.3 million from GATX and $899.0 million from Brookfield. As of March 31, 2026, GABX is a consolidated variable interest entity and is reported in the Rail North America segment. See "Note 3. Asset Acquisition" and "Note 7. Variable Interest Entities" for further information about the transaction and GABX consolidation.

On the same date, GATX directly purchased 200 locomotives from Wells Fargo for approximately $30.4 million, and Brookfield directly acquired Wells Fargo's rail finance lease portfolio, consisting of approximately 22,000 railcars and approximately 400 locomotives. GATX serves as manager of the railcars in GABX as well as the finance lease portfolio directly owned by Brookfield and earns management fees for such services.

**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 three months ended March 31, 2026 are not necessarily indicative of the results we may achieve for the entire year ending December 31, 2026. 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, 2025.

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

**NOTE 3. Asset Acquisition**

On January 1, 2026, GATX acquired approximately 101,000 railcars for $4.2 billion from Wells Fargo through the newly formed GABX joint venture with Brookfield. Initially, GATX's ownership share of GABX is 30% with Brookfield's share at 70%. GATX will have the option to acquire up to 100% of GABX's equity through a series of annual call options that allow GATX to purchase a percentage of Brookfield's equity every year for up to 25 years, beginning in June 2026. The transaction was funded through a $2.96 billion term loan executed by GABX, which is guaranteed by GATX, and equity contributions of $385.3 million from GATX and $899.0 million from Brookfield. As of March 31, 2026, GABX is a consolidated variable interest entity and is reported in the Rail North America segment. See "Note 7. Variable Interest Entities" for further information.

We determined the acquisition of Wells Fargo's rail assets represented an asset acquisition in accordance with Accounting Standards Codification ("ASC") Topic 805, *Business Combinations*, as the fair value of substantially all of the assets acquired were concentrated in a group of similar assets. The cost of the asset acquisition was allocated to the assets on a relative fair value basis. We determined fair value of the assets using estimates of discounted future cash flows, independent appraisals, and market comparables. Transaction costs incurred to acquire the assets were capitalized and included in the cost basis of the acquired assets.

On the same date, GATX directly purchased 200 locomotives from Wells Fargo for approximately $30.4 million, and Brookfield directly acquired Wells Fargo's rail finance lease portfolio, consisting of approximately 22,000 railcars and approximately 400 locomotives. GATX serves as manager of the railcars in GABX as well as the finance lease portfolio directly owned by Brookfield and earns management fees for such services.

**NOTE 4. 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 three categories as presented on our statement of income:

*Lease Revenue*

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

------

**GATX CORPORATION AND SUBSIDIARIES**

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

*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 generally offer stand-alone maintenance service contracts. Operating lease revenue is within the scope of 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 probable. See "Note 6. Leases".

*Finance Lease Revenue*

In certain cases, we lease railcars and tank containers that, at lease inception or upon modification, 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 6. 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 plc and its affiliates (collectively "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.

*Other Revenue*

Other revenue is composed of customer liability repair revenue, management fees, 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 variable lease components is recognized when earned, in accordance with Topic 842. Management fees consist of fees GATX earns as manager of the railcars in GABX as well as the finance lease portfolio directly owned by Brookfield. Management fees earned from GABX are eliminated in consolidation but are reflected in net income attributable to GATX.

**NOTE 5. Operating Assets and Facilities**

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

---

| | | |
|:---|:---|:---|
| | **March 31<br>2026** | **December 31<br>2025** |
| Railcars and locomotives | $17880.1 | $13802.1 |
| Aircraft spare engines | 1177.7 | 1177.5 |
| Tank containers | 277.3 | 278.0 |
| Buildings, leasehold improvements, and other equipment | 322.8 | 318.5 |
| Other | 123.0 | 86.5 |
|  | $19780.9 | $15662.6 |
| Less: allowance for depreciation | (4328.3) | (4251.7) |
| Net operating assets and facilities | $15452.6 | $11410.9 |

---

Total depreciation expense was $174.6 million for the three months ended March 31, 2026 and $108.4 million for the three months ended March 31, 2025.

**GATX CORPORATION AND SUBSIDIARIES**

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

**NOTE 6. 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<br>March 31** | **Three Months Ended<br>March 31** |
| | **2026** | **2025** |
| Operating lease revenue: |  |  |
| &nbsp;&nbsp;&nbsp;Fixed lease revenue | $484.4 | $330.8 |
| &nbsp;&nbsp;&nbsp;Variable lease revenue | 30.2 | 25.6 |
| Total operating lease revenue | $514.6 | $356.4 |
| Finance lease revenue | 4.1 | 3.2 |
| Total lease revenue | $518.7 | $359.6 |

---

In accordance with the terms of our leases with customers, we may earn additional revenue, primarily for customer repairs. This additional revenue is reported in other revenue in the condensed statements of income and was $34.6 million for the three months ended March 31, 2026 and $33.9 million for the three months ended March 31, 2025.

We recorded gains on finance leases of $4.9 million for the three months ended March 31, 2026 and $3.5 million for the three months ended March 31, 2025. The gains are reported in net gain on asset dispositions in the condensed statements of income.

**NOTE 7. Variable Interest Entities**

We evaluate our interests in other entities to determine whether those entities are variable interest entities ("VIEs") and whether we are the primary beneficiary of any such VIE in accordance with ASC Topic 810, *Consolidation*.

To determine if we are the primary beneficiary of a VIE, we assess whether we have the power to direct the activities that most significantly impact the economic performance of the entity as well as the obligation to absorb losses or the right to receive benefits that may be significant to the entity. These determinations are both qualitative and quantitative, and they require us to make judgments and assumptions about the entity's forecasted financial performance and the volatility inherent in those forecasted results. If we determine we are the primary beneficiary of the VIE, we consolidate the entity in our financial statements. We evaluate new investments at inception and regularly review all existing entities for events that may affect our determination of whether an entity is a VIE and, if so, whether we are the primary beneficiary.

***GABX***

In 2025, GABX was formed by GATX and Brookfield with the objective to acquire the Wells Fargo railcar fleet. In December 2025, GABX was funded with equity contributions of $385.3 million and $899.0 million from GATX and Brookfield, respectively, and GABX executed a $2.96 billion term loan, guaranteed by GATX, in anticipation of closing the Wells Fargo transaction. On January 1, 2026, GABX acquired approximately 101,000 railcars for $4.2 billion from Wells Fargo, and GATX began serving as manager of the railcars for GABX. As of March 31, 2026, GATX ownership in GABX was 30%.

We evaluated our interests in GABX and determined that GABX is a VIE. We concluded that we are the primary beneficiary of GABX as we have the power to direct the activities that most significantly impact the economic performance of GABX over the course of the expected life of the entity, primarily through the management services agreement. As a result, we consolidate GABX in our financial statements.

------

**GATX CORPORATION AND SUBSIDIARIES**

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

GABX owns and leases railcars and, therefore, the activities and risks at GABX are similar to those of our wholly owned railcar leasing activities.

---

_________

(1)&nbsp;&nbsp;&nbsp;&nbsp;Amount includes $12.5 million of management fees paid to GATX in the three months ended March 31, 2026. Management fees are primarily based on the number of railcars under management and are consistent with market rates.

(2)&nbsp;&nbsp;&nbsp;&nbsp;Represents income taxes directly attributable to GABX. Certain of GABX's jurisdictions are disregarded jurisdictions for income tax purposes and, as a result, income taxes are incurred at the shareholder level.

In the three months ended March 31, 2026, significant cash flow items at GABX included $4,230.8 million of cash paid for the acquisition of operating assets, $992.0 million of net proceeds from the issuance of debt, and $992.0 million of cash paid for the repayment of debt.

**GATX CORPORATION AND SUBSIDIARIES**

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

**NOTE 8. Fair Value** 

The assets and liabilities that GATX records at fair value on a recurring basis consisted entirely of derivatives at March 31, 2026 and December 31, 2025.

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 one instrument outstanding with an aggregate notional amount of $50.0 million as of March 31, 2026 that matures in 2027 and one instrument outstanding with an aggregate notional amount of $50.0 million as of December 31, 2025 that matures in 2027.

*Cash Flow Hedges*

We use U.S. Treasury rate locks, swap rate locks, and interest rate swaps 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 fifteen instruments outstanding with a notional amount of $1,763.0 million as of March 31, 2026 that mature in 2026 to 2030 and three instruments outstanding with a notional amount of $2,370.6 million as of December 31, 2025 that each mature in 2031. Within the next 12 months, we expect to reclassify $5.3 million ($4.8 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 income (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 $11.2 million as of March 31, 2026 and $28.5 million as of December 31, 2025. 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 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.

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

The service cost component of net periodic cost was $1.5 million for three months ended March 31, 2026 and $1.4 million for the three months ended March 31, 2025 and is reported in selling, general and administrative expense.

The non-service components totaled income of $0.9 million for the three months ended March 31, 2026 and $1.1 million for the three months ended March 31, 2025 and are reported in other income (expense) in the statements of income.

**NOTE 10. Share-Based Compensation** 

During the three months ended March 31, 2026, we granted 195,800 non-qualified employee stock options, 25,514 restricted stock units, 31,380 performance shares, and 1,125 restricted stock units awarded to non-employee directors. For the three months ended March 31, 2026, total share-based compensation expense was $5.8 million and the related tax benefits were $1.4 million. For the three months ended March 31, 2025, total share-based compensation expense was $6.1 million and the related tax benefits were $1.5 million.

The estimated fair value of our 2026 non-qualified employee stock option awards and related underlying assumptions are shown in the table below:

---

| | |
|:---|:---|
| | **2026** |
| Weighted-average estimated fair value | $54.92 |
| Quarterly dividend rate | $0.66 |
| Expected term of stock options, in years | 4.2 |
| Risk-free interest rate | 3.5% |
| Dividend yield | 1.3% |
| Expected stock price volatility | 24.9% |
| Present value of dividends | $10.32 |

**NOTE 11. Income Taxes** 

The following table shows our effective income tax rate for the three months ended March 31:

---

| | | |
|:---|:---|:---|
| | **2026** | **2025** |
| &nbsp;&nbsp;Effective income tax rate | 26.7% | 23.6% |

---

The increase in the effective tax rate for the three months ended March 31, 2026 compared to the three months ended March 31, 2025 was primarily due to the impact of the structure of our ownership interest in the GABX joint venture and the mix of income between jurisdictions where it is taxed at 100% and jurisdictions where it is disregarded for income tax purposes and only taxed at the shareholder ownership percentage. The rate in both periods included incremental benefits associated with equity awards vested or exercised and a mix of pre-tax income among domestic and foreign jurisdictions, which are taxed at different rates.

**NOTE 12. 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.

As of March 31, 2026 and December 31, 2025, we had commercial commitments of $9.8 million and $9.9 million, respectively, consisting of standby letters of credit and performance bonds. There were no liabilities recorded on the balance sheet for commercial commitments at March 31, 2026 and December 31, 2025. As of March 31, 2026, our outstanding commitments expire in 2026 through 2028. 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 13. 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 non-forfeitable rights to dividends or dividend equivalents and are therefore not classified as participating securities.

The following table shows the computation of our basic and diluted earnings per common share (in millions, except per share amounts):

**NOTE 15. Non-Controlling Interest**

Non-controlling interest represents the portion of our consolidated net assets that are not wholly owned and therefore not attributable to GATX. Non-controlling interest was established in December 2025 as a result of the creation and funding of the GABX joint venture. In 2025, Brookfield contributed $899.0 million of equity to GABX for its share of ownership. On January 1, 2026, GABX acquired approximately 101,000 railcars for $4.2 billion from Wells Fargo. As of March 31, 2026, the non-controlling interest represents Brookfield's 70% ownership in GABX.

GATX has the right to acquire up to 100% of GABX through a series of annual call options that allow GATX to purchase a percentage of Brookfield's equity every year for up to 25 years, beginning in June 2026. The value of the call options is embedded within the non-controlling interest, rather than bifurcated and accounted for separately, as we have determined that the call options are clearly and closely related to the non-controlling interest.

The following table shows the change in non-controlling interest (in millions):

|:---|:---|:---|
| | **Three Months Ended<br>March 31** | **Three Months Ended<br>March 31** |

**NOTE 16. 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. For a full discussion of our pending legal matters, please refer to "Note 24. Legal Proceedings and Other Contingencies" included with our consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2025.

**NOTE 17. Financial Data of Business Segments** 

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

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. Financial results for Trifleet are reported in the Other segment.

The Rail North America reportable segment 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 provides other ancillary services. As of December 31, 2025, GABX is consolidated in the Rail North America operating segment and, for 2025, is primarily composed of the equity contributions from GATX and Brookfield, as well as the debt undertaken, in anticipation of the closing of the transaction and purchase of railcars from Wells Fargo. GABX's operations are reflected within that segment beginning on January 1, 2026 upon closing of the transaction. GATX serves as manager of the finance lease portfolio directly owned by Brookfield for which we earned $2.8 million in management fees in the three months ended March 31, 2026.

Rail International is an aggregation of our operating segments in Europe ("GATX Rail Europe" or "GRE") and India ("Rail India"). 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.

Engine Leasing is composed of our engine leasing operations, which include our ownership interest in the Rolls-Royce & Partners Finance joint ventures (collectively, the "RRPF affiliates"), a group of joint ventures with Rolls-Royce that lease aircraft spare engines, and GATX Engine Leasing ("GEL"), our wholly owned business that directly owns aircraft spare engines that are leased to airline customers or employed in engine capacity agreements. All engines owned by GEL are managed by the RRPF affiliates, for

which we paid them a fee of $1.5 million in the three months ended March 31, 2026 and $1.4 million in the three months ended March 31, 2025.

Other includes Trifleet operations and certain other amounts not allocated to the segments. Selling, general, and administrative expenses and income taxes are reported on a consolidated basis.

Segment profit is an internal performance measure reported to GATX's President and Chief Executive Officer, our chief operating decision maker ("CODM"), for purposes of assessing performance and allocating capital and resources to 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. We have disclosed in each segment the significant expense categories that are reviewed by the CODM, and there are no additional significant expenses within the expense categories presented in the segment tables. The CODM uses segment profit during the annual budget and forecasting processes and considers comparisons of actual segment profit against budget, forecast, and prior periods to assess current period performance and when making decisions about allocating capital and resources to each segment.

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

The following discussion and analysis of the financial condition and results of operations of GATX Corporation ("GATX", the "Company," "we," "us," "our," and similar terms) should be read in conjunction with our consolidated financial statements and related notes and other information included elsewhere in this Quarterly Report, our Annual Report on Form 10-K for the year ended December 31, 2025, 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 principles ("GAAP") and on certain other financial data that we prepared using non-GAAP components. For a reconciliation of these non-GAAP measures to the most comparable GAAP measures, 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, 2025 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** 

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. Financial results for our tank container leasing business ("Trifleet") are reported in the Other segment.

Operating results for the three months ended March 31, 2026 are not necessarily indicative of the results we may achieve for the entire year ending December 31, 2026. 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, 2025.

On January 1, 2026, GATX acquired approximately 101,000 railcars for $4.2 billion from Wells Fargo Bank, N.A. ("Wells Fargo") through a newly formed joint venture ("GABX" or the "GABX joint venture") with Brookfield Infrastructure Partners L.P. and its institutional partners (collectively, "Brookfield"). Initially, GATX's ownership share of GABX is 30% with Brookfield's share at 70%. GATX will have the option to acquire up to 100% of GABX's equity over time. See "Note 15. Non-Controlling Interest" in Part I, Item 1 of this Quarterly Report on Form 10-Q for further information about the options to acquire GABX's equity. The transaction was partially funded through a $2.96 billion term loan executed by GABX, which is guaranteed by GATX. As of March 31, 2026, GABX is consolidated and is reported in the Rail North America segment. GATX also directly purchased approximately 200 locomotives from Wells Fargo for approximately $30.4 million, and Brookfield directly acquired Wells Fargo's rail finance lease portfolio, consisting of approximately 22,000 railcars and approximately 400 locomotives. GATX serves as manager of the railcars in GABX as well as the finance lease portfolio directly owned by Brookfield and earns management fees for such services. See "Note 1. Description of Business" in Part I, Item 1 of this Quarterly Report on Form 10-Q for further information.

**Economic Conditions**

GATX, and markets more broadly, are facing heightened uncertainty related to trade policy, geopolitical tensions, and overall economic conditions. These conditions did not have a significant impact on our business and financial results during the first three months of 2026. However, recent developments, including newly announced tariffs and the ongoing conflict with Iran, have increased economic uncertainty and could have a more significant impact on GATX's financial results in the future. For example, geopolitical tensions in the Middle East could increase energy prices, disrupt supply chains, reduce global air travel, and negatively impact our customers. A sustained economic slowdown resulting from these or other factors could impact GATX directly and indirectly, including through higher costs for new railcars or other assets or softening demand for our products and services. Management continues to monitor the macroeconomic and geopolitical environment closely to identify potential risks and to manage our business accordingly. However, we believe we are in a strong position to manage these risks due to our diverse fleet, broad global customer base, long-term lease portfolio, strong balance sheet, and access to capital.

**DISCUSSION OF OPERATING RESULTS**

Net income attributable to GATX for the three months ended March 31, 2026 was $85.5 million, or $2.35 per diluted share, compared to $78.6 million, or $2.15 per diluted share, for the same period in 2025. Net income attributable to GATX increased $6.9 million compared to the prior year and was impacted by the Wells Fargo rail assets acquisition. The variance was largely due to higher revenue at Rail North America and Rail International and higher net gain on asset dispositions at Rail North America, partially offset by higher maintenance expense and depreciation expense at Rail North America, higher interest expense, and lower earnings at the Rolls-Royce & Partners Finance joint ventures (collectively, the "RRPF affiliates").

**Segment Operations**

Segment profit is an internal performance measure reported to GATX's President and Chief Executive Officer for purposes of assessing performance and allocating capital and resources to 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.

***RAIL NORTH AMERICA***

**Segment Summary** 

On January 1, 2026, GATX acquired approximately 101,000 railcars for $4.2 billion from Wells Fargo through the GABX joint venture. GABX is consolidated within the Rail North America segment. See "Note 7. Variable Interest Entities" in Part I, Item 1 of this Quarterly Report on Form 10-Q for quantification of the impacts of this acquisition. On the same date, GATX directly purchased 200 locomotives from Wells Fargo for approximately $30.4 million.

GATX serves as manager of the railcars in GABX as well as the finance lease portfolio directly owned by Brookfield and earns management fees for such services. In the three months ended March 31, 2026, GABX paid GATX $12.5 million and Brookfield paid GATX $2.8 million in management fees for these services. GABX management fees earned by GATX are eliminated in consolidation and not shown on the face of the consolidated income statement. However, the impact of fees earned are included in net income attributable to GATX. Management fees earned by GATX for managing the finance lease portfolio directly owned by Brookfield are reported in other revenue.

Demand for most railcars was stable, despite ongoing macroeconomic uncertainty and the impacts of the geopolitical environment in the Middle East, and the renewal success rate remained strong. Utilization was 98.1% at the end of the current quarter.

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

(2)&nbsp;&nbsp;&nbsp;&nbsp;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)&nbsp;&nbsp;&nbsp;&nbsp;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 newly built railcars, railcars purchased in the secondary market, and the disposition of railcars that were sold or scrapped, as well as the fleet utilization rate.

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

As of March 31, 2026, leases for 29,052 tank and freight cars and 1,289 boxcars are scheduled to expire over the remainder of 2026. These amounts exclude railcars on leases expiring in 2026 that have already been renewed or assigned to a new lessee.

In 2022, we entered into a 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 March 31, 2026, 8,437 railcars have been ordered pursuant to the terms of the agreement, of which 6,745 railcars have been delivered.

![2467](gmt-20260331_g2.jpg)

**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 first quarter of 2026, the renewal rate change of the LPI was positive 22.3%, compared to positive 21.9% in the prior quarter, and positive 24.5% in the first quarter of 2025. Lease terms on renewals for railcars in the LPI averaged 56 months in the current quarter, compared to 58 months in the prior quarter, and 61 months in the first quarter of 2025.

***Comparison of Reported Results for the First Quarter of 2026 to the First Quarter of 2025***

**Segment Profit**

In the three months ended March 31, 2026, segment profit of $103.9 million increased 17.0% compared to $88.8 million for the same period in the prior year. Segment profit in 2026 was impacted by the acquisition of railcars from Wells Fargo. Aside from the impact of the acquisition, segment profit increased $22.1 million, driven by higher net gains on asset dispositions and higher revenue from the legacy fleet, partially offset by higher maintenance and interest expense.

**Revenues**

In the three months ended March 31, 2026, lease revenue increased $140.7 million, or 54.1%. The acquisition of railcars from Wells Fargo led to an increase in lease revenue of $132.8 million. In addition to the impact of the acquisition, lease revenue increased $7.9 million, primarily driven by more railcars on lease and higher lease rates. Other revenue increased $2.7 million, driven by management fee revenue from the finance lease portfolio owned by Brookfield and managed by GATX.

**Expenses**

In the three months ended March 31, 2026, maintenance expense increased $36.9 million. The acquisition of railcars from Wells Fargo led to an increase of $26.5 million. In addition to this impact, maintenance expense increased $10.4 million, driven by more repairs performed by the railroads, more repair events and a mix of repairs that resulted in higher costs per repair. Depreciation expense increased $56.3 million, primarily due to the impact of the railcars acquired from Wells Fargo.

**Other Income (Expense)**

In the three months ended March 31, 2026, net gain on asset dispositions increased $17.7 million, driven by higher net gains on asset dispositions and railcars converted to finance leases 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 $49.3 million, due to a higher average debt balance, resulting from debt incurred for the acquisition of railcars from Wells Fargo, and a higher average interest rate.

**Investment Volume**

During the three months ended March 31, 2026, investment volume was $4,464.2 million (including approximately $4.2 billion for the acquisition of railcars and locomotives from Wells Fargo) compared to $227.7 million in the same period in 2025. We acquired 1,064 newly built railcars, 100,920 railcars in the secondary market (including 100,870 railcars acquired at GABX from Wells Fargo) and 200 locomotives from Wells Fargo in the three months ended March 31, 2026, compared to 642 newly built railcars, 627 railcars in the secondary market, and zero locomotives in the same period in 2025.

Our investment volume is predominantly composed of acquired railcars, but also includes the acquisition of locomotives and 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.

***RAIL INTERNATIONAL***

**Segment Summary** 

Rail International, composed primarily of GATX Rail Europe ("GRE"), experienced a challenging railcar leasing market as GRE faced ongoing macroeconomic headwinds, including weak GDP results, and uncertainty due to the geopolitical environment in the Middle East and Ukraine, which weighed on customers' fleet planning activities. Despite pressure on utilization, GRE experienced renewal lease rate increases for the majority of railcar types in the period. Utilization was 94.7% at the end of the current quarter.

The fleet size of our rail business in India ("Rail India") continued to grow during the current quarter, as 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 strong, driven by continued growth in the economy and infrastructure development. Utilization was 100.0% at the end of the current quarter.

***Comparison of Reported Results for the First Quarter of 2026 to the First Quarter of 2025***

**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 March 31, 2026, fluctuations in the value of the euro, relative to the U.S. dollar, positively impacted lease revenue by approximately $8.6 million and positively impacted segment profit, excluding other income (expense), by approximately $4.4 million compared to the same period in 2025.

------

**Segment Profit** 

In the three months ended March 31, 2026, segment profit of $31.6 million increased 23.0% compared to $25.7 million for the same period in the prior year. The increase was primarily due to higher lease revenue and changes in foreign currency exchange rates, partially offset by higher depreciation and interest expense.

**Revenues**

In the three months ended March 31, 2026, lease revenue increased $16.8 million, or 20.1%, driven by more railcars on lease at GRE and Rail India, as well as the impact of foreign exchange rates.

**Expenses**

In the three months ended March 31, 2026, maintenance expense increased $0.6 million, primarily due to the impact of foreign exchange rates, partially offset by fewer repair events, the mix of repairs performed, and fewer regulatory compliance events. Depreciation expense increased $7.7 million, due to the impact of new railcars added to the fleet, including the railcars acquired from DB Cargo AG primarily in 2025.

**Other Income (Expense)**

In the three months ended March 31, 2026, net interest expense increased $5.9 million, due to a higher average debt balance and a higher average interest rate. Other income (expense) was favorable by $4.3 million, driven by the positive impact of changes in foreign exchange rates, primarily euro-zloty fluctuations, and lower litigation costs.

**Investment Volume**

During the three months ended March 31, 2026, investment volume was $47.4 million compared to $62.7 million in the same period in 2025. In the three months ended March 31, 2026, GRE acquired 355 newly built railcars compared to 446 newly built railcars for the same period in 2025, and Rail India acquired 343 newly built railcars compared to 312 newly built railcars for the same period in 2025.

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 railcar types acquired, as well as fluctuations in the exchange rates of the foreign currencies in which Rail International conducts business.

***ENGINE LEASING***

**Segment Summary** 

Engine Leasing includes the RRPF affiliates, a group of 50% owned domestic and foreign joint ventures with Rolls-Royce plc (or affiliates thereof, collectively "Rolls-Royce"), a leading manufacturer of commercial aircraft jet engines. Segment profit included earnings from the RRPF affiliates of $27.6 million for the three months ended March 31, 2026, compared to $33.4 million for the same period in 2025. The change was driven by the timing of remarketing income.

Engine Leasing also includes GATX Engine Leasing ("GEL"), our wholly owned business that invests directly in aircraft spare engines. As of March 31, 2026, GEL owned 46 aircraft spare engines, with 21 on long-term leases with airline customers and 25 that are employed in an engine capacity agreement with Rolls-Royce for use in its engine maintenance programs. All engines owned by GEL are managed by the RRPF affiliates, for which we paid them a fee of $1.5 million for the three months ended March 31, 2026 and $1.4 million for the same period in 2025.

The operating environment for the RRPF affiliates and GEL continued to be favorable in the first quarter of 2026 as robust global passenger air travel continued to drive strong demand for aircraft spare engines. However, uncertainty exists due to the geopolitical environment in the Middle East.

***Comparison of Reported Results for the First Quarter of 2026 to the First Quarter of 2025***

**Segment Profit**

In the three months ended March 31, 2026, segment profit of $35.3 million decreased $3.3 million compared to segment profit of $38.6 million for the same period in the prior year. The decrease was driven by lower earnings at the RRPF affiliates, primarily due to the timing of remarketing events, partially offset by higher earnings at GEL.

**Revenues**

In the three months ended March 31, 2026, lease revenue increased $1.4 million, driven by aircraft spare engines acquired and placed on leases directly with airline customers. Non-dedicated engine revenue increased $0.6 million, due to higher annuity receipts resulting from higher average engine flying hours for aircraft spare engines utilized in the engine capacity agreement with Rolls-Royce.

**Expenses**

&nbsp;&nbsp;&nbsp;&nbsp;

In the three months ended March 31, 2026, depreciation expense increased $1.2 million, due to aircraft spare engines acquired in 2025.

------

**Other Income (Expense)**

In the three months ended March 31, 2026, income from our share of affiliates' earnings decreased $5.8 million, driven by the timing of remarketing income. Higher income from operations was primarily due to more aircraft spare engines in the fleet, partially offset by higher interest expense. 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 three months ended March 31, 2026, investment volume was $0.2 million, compared to zero in the same period in 2025. Investment volume in 2026 consisted of the purchase of engine stands.

***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.

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

---

| | | |

---

_________

(1)&nbsp;&nbsp;&nbsp;&nbsp;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 $14.7 million in the three months ended March 31, 2026 compared to the same period in the prior year. The variance was primarily due to higher employee-related expenses, including the impact of higher headcount resulting from the Wells Fargo rail assets acquisition, and higher information technology expenses.

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.

**Consolidated Income Taxes**

See "Note 11. 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 debt. 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 March 31, 2026, we had an unrestricted cash balance of $740.9 million. We also have a $632 million, 5-year unsecured revolving credit facility in the United States that matures in 2030 and a $368 million, 3-year unsecured revolving credit facility in the United States that matures in 2028, both of which were fully available as of March 31, 2026. In addition, we have a €250 million, 3-year unsecured revolving credit facility in Europe that matures in 2027, of which €210 million was available as of March 31, 2026. At GABX, we have a $250 million 5-year unsecured revolving credit facility in the United States that matures in 2030, all of which was fully available as of March 31, 2026.

The following table shows our cash flows from operating, investing, and financing activities for the three months ended March 31 (in millions):

---

| | | |
|:---|:---|:---|
| | **2026** | **2025** |
| Net cash provided by operating activities | $199.1 | $124.2 |
| Net cash used in investing activities | (4358.7) | (234.7) |
| Net cash (used in) provided by financing activities | (82.6) | 461.6 |
| Effect of exchange rate changes on cash, cash equivalents, and restricted cash | (1.7) | 4.7 |
| Net (decrease) increase in cash, cash equivalents, and restricted cash during the period | $(4243.9) | $355.8 |

---

***Net Cash Provided by Operating Activities***

Net cash provided by operating activities for the three months ended March 31, 2026 increased $74.9 million compared to the same period in 2025. Comparability among reporting periods is impacted by the timing of changes in working capital items. Specifically, higher cash receipts from revenue and lower payments for operating leases were partially offset by higher payments for interest, income taxes, maintenance, and other operating expenses.

------

***Net Cash Used in Investing Activities***

The following table shows our principal sources and uses of cash flows from investing activities for the three months ended March 31 (in millions):

---

| | | |
|:---|:---|:---|
| | **2026** | **2025** |
| Portfolio investments and capital additions (1) | $(4520.0) | $(296.3) |
| Portfolio proceeds (2) | 152.4 | 68.3 |
| Purchases of assets previously leased (3) | (3.8) | (15.0) |
| Proceeds from sales of other assets (4) | 11.5 | 7.1 |
| Other investing activity | 1.2 | 1.2 |
| Net cash used in investing activities | $(4358.7) | $(234.7) |

---

_________

(1)&nbsp;&nbsp;&nbsp;&nbsp;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)&nbsp;&nbsp;&nbsp;&nbsp;Portfolio proceeds primarily consist of proceeds from sales of operating assets.

(3)&nbsp;&nbsp;&nbsp;&nbsp;In 2026, we purchased 187 railcars that were previously on operating leases, compared to 802 railcars in 2025.

(4)&nbsp;&nbsp;&nbsp;&nbsp;Proceeds from sales of other assets were primarily related to railcar scrapping.

The increase in portfolio investments and capital additions of $4,223.7 million for the three months ended March 31, 2026 was primarily due to the acquisition of railcars and locomotives from Wells Fargo and the cost of other railcars acquired at Rail North America, partially offset by fewer railcars acquired at GRE. The timing of investments depends on purchase commitments, transaction opportunities, and market conditions.

Portfolio proceeds increased by $84.1 million for the three months ended March 31, 2026, primarily due to more railcars sold at Rail North America.

**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, distributions from affiliates, issuances of debt, commercial paper issuances, and committed revolving credit facilities.

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 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.

We have a $632 million 5-year unsecured revolving credit facility in the United States that matures in May 2030. This facility contains a one-year extension option. As of March 31, 2026, the full $632 million was available under this facility. Additionally, we have a $368 million 3-year unsecured revolving credit facility in the United States that matures in May 2028. This facility contains a one-year extension option. As of March 31, 2026, the full $368 million was available under this facility.

GABX has a $250 million 5-year unsecured revolving credit facility in the United States that matures in 2030. As of March 31, 2026, the full $250 million was available under this facility.

In Europe, we have a €250 million, 3-year unsecured revolving credit facility that matures in December 2027. As of March 31, 2026, €210 million was available under this credit facility. In addition, our European subsidiaries have smaller unsecured credit facilities with an aggregate limit of €25.0 million. As of March 31, 2026, €22.0 million was available under these credit facilities, as €3.0 million ($3.5 million) was drawn. The weighted average interest rate of these outstanding borrowings during the three months ended March 31, 2026 was 3.0%.

***Delayed Draw Term Loans***

As of March 31, 2026, we had INR 2.0 billion ($21.1 million) available under an outstanding delayed draw term loan in India.

------

***Restrictive Covenants***

Our $632 million and $368 million revolving credit facilities in the United States, and our €250 million revolving credit facility in Europe, 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. Certain exceptions to the covenants permit us to incur an unlimited amount of purchase money and nonrecourse indebtedness.

The GABX term loan and $250 million revolving credit facility contain various restrictive covenants, including a requirement to maintain an asset coverage ratio.

At March 31, 2026, our European rail subsidiaries had outstanding term loans, public debt, and private placement debt balances totaling €1,065.0 million, and Trifleet had an outstanding term loan of €113.0 million. The loans are guaranteed by GATX Corporation and are subject to similar restrictive covenants as the GATX and GRE revolving credit facilities noted above. In addition, Rail India had outstanding term loans of INR 12.4 billion ($130.8 million) that are subject to certain restrictive covenants.

At March 31, 2026, we were in compliance with all covenants and conditions of all of our credit agreements, indentures, and loans. 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 March 31, 2026:

***GATX Common Stock Repurchases***

On January 25, 2019, our Board of Directors approved a $300.0 million share repurchase program (the "Prior Repurchase Program"), pursuant to which we were 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. On February 18, 2026, the Board terminated the Prior Repurchase Program and approved a new $300.0 million share repurchase program (the "New 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 New Repurchase Program 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 share repurchases will be dependent on market conditions and other factors.

During the three months ended March 31, 2026, we repurchased 21,587 shares of common stock for $3.8 million, excluding commissions, under the New Repurchase Program compared to 12,046 shares of common stock for $1.9 million during the same period in 2025 under the Prior Repurchase Program. As of March 31, 2026, $296.2 million remained available under the New Repurchase Program authorization.

**CRITICAL ACCOUNTING POLICIES AND ESTIMATES**

There have been no changes to our critical accounting policies during the three months ended March 31, 2026. Refer to our Annual Report on Form 10-K for the year ended December 31, 2025 for a summary of our policies.

**NON-GAAP FINANCIAL MEASURES**

**&nbsp;&nbsp;&nbsp;&nbsp;**

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 measures to the most directly comparable GAAP measures.

**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 attributable to GATX, diluted earnings per share, and return on equity attributable to GATX because we believe these items are not attributable to our business operations. Management utilizes net income attributable to GATX, 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.

There were no tax adjustments and other items impacting net income or diluted earnings per share for either the first quarter of 2026 or 2025. However, we did have tax adjustments and other items impacting net income in other periods used in the calculation of the applicable measures for the trailing 12 months ended March 31, 2026 and 2025.

------

The following tables show our net income and return on equity, excluding tax adjustments and other items, for the trailing 12 months ended March 31 (in millions):

On February 18, 2026, the Board terminated the Prior Repurchase Program and approved a new $300.0 million share repurchase program (the "New 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.

During the first quarter of 2026, we repurchased 21,587 shares of common stock for $3.8 million under the New Repurchase Program, compared to 12,046 share repurchases for $1.9 million completed during the first quarter of 2025 under the Prior Repurchase Program.
