Notes to Consolidated Financial Statements
(Unaudited)
Note 1. Summary of Significant Accounting Policies
Basis of Presentation
The foregoing Consolidated Financial Statements are unaudited and have been prepared from the books and records of Trinity Industries, Inc. and Subsidiaries (“Trinity,” “Company,” “we,” “our,” or "us"), which include the accounts of our wholly-owned subsidiaries and partially-owned subsidiaries, TRIP Rail Holdings LLC (“TRIP Holdings”), RIV 2013 Rail Holdings LLC ("RIV 2013"), and Trinity Global Ventures Limited ("Trinity Global Ventures"), in which we have a controlling interest. In our opinion, all normal and recurring adjustments necessary for a fair presentation of our financial position as of September 30, 2025, the results of operations for the three and nine months ended September 30, 2025 and 2024, and cash flows for the nine months ended September 30, 2025 and 2024 have been made in conformity with generally accepted accounting principles. All significant intercompany accounts and transactions have been eliminated. Certain prior year balances have been reclassified to conform to the 2025 presentation.
Due to seasonal and other factors, the results of operations for the nine months ended September 30, 2025 may not be indicative of expected results of operations for the year ending December 31, 2025. These interim financial statements and notes are condensed as permitted by the instructions to Form 10-Q and should be read in conjunction with our audited Consolidated Financial Statements included in our Form 10-K for the year ended December 31, 2024.
Revenue Recognition
Revenue associated with our railcar lease contracts is recognized in accordance with Accounting Standards Codification ("ASC") 842, Leases. Revenue associated with our railcar manufacturing, maintenance services, and digital and logistics services businesses, as well as certain servicing, maintenance, and management agreements, is recognized in accordance with ASC 606, Revenue from Contracts with Customers.
Revenue is measured based on the allocation of the transaction price in a contract to satisfied performance obligations. The transaction price does not include any amounts collected on behalf of third parties. We recognize revenue when we satisfy a performance obligation by transferring control over a product or service to a customer. For all contracts with customers, we evaluate whether we are the principal (i.e., report revenues on a gross basis) or agent (i.e., report revenues on a net basis). Generally, we are the principal in our contracts with customers and report revenues on a gross basis as we control the product or service before it is transferred to a customer. We act as an agent for a small number of service contracts and report those revenues on a net basis as we do not control the services before they are provided to the customer. Payments for our products and services are generally due within normal commercial terms.
The following is a description of principal activities from which we generate our revenue, separated by reportable segments. See Note 4 for a further discussion regarding our reportable segments.
Railcar Leasing and Services Group
In our Railcar Leasing and Services Group ("Leasing Group"), revenue from rentals and operating leases, including contracts that contain non-level fixed lease payments, is recognized monthly on a straight-line basis. When certain criteria are met, leases not classified as operating leases are generally classified as sales-type leases.
We review our operating lease receivables for collectibility on a regular basis, taking into consideration changes in factors such as the lessee’s payment history, the financial condition of the lessee, and business and economic conditions in the industry in which the lessee operates. In the event that the collectibility of a receivable with respect to any lessee is no longer probable, we derecognize the revenue and related receivable and recognize future revenue only when the lessee makes a rental payment. Contingent rents are recognized when the contingency is resolved.
Selling profit or loss associated with sales-type leases is recognized upon lease commencement, and a net investment in the sales-type lease is recorded in the Consolidated Balance Sheets. Interest income related to sales-type leases is recognized over the lease term using the effective interest method. Selling profit or loss associated with sales-type leases is presented in the gains on dispositions of other property line in our Consolidated Statements of Operations. See "Lease Accounting" below for additional information regarding sales-type leases.

Table of Contents
We report all sales of railcars from the lease fleet as a net gain or loss from the disposal of a long-term asset in accordance with ASC 610-20, Gains and losses from the derecognition of non-financial assets. Sales of railcars from the lease fleet are presented in the Lease portfolio sales line in our Consolidated Statements of Operations.
Our maintenance services business is primarily dedicated to servicing our lease fleet. Revenues related to maintenance services performed on Company-owned railcars under full-service lease agreements are eliminated within the Railcar Leasing and Services Group. Services that are not included in the full-service lease agreement, such as repairs of railcar damage or other customer-specific requirements, as well as maintenance and repair activities on railcars owned by third parties, including our investor-owned fleet, are reflected in the Leasing Group's revenues and are not eliminated in consolidation.
Within maintenance services, revenue is recognized over time as repair and maintenance projects are completed, using an input approach based on the costs incurred relative to the total estimated costs of performing the project. We recorded contract assets of $10.5 million and $9.6 million as of September 30, 2025 and December 31, 2024, respectively, related to unbilled revenues recognized on repair and maintenance activities that have been performed, but for which the entire project has not yet been completed, and the railcar has not yet been shipped to the customer. These contract assets are included within the Receivables, net of allowance line in our Consolidated Balance Sheets.
Rail Products Group
Our railcar manufacturing business recognizes revenue related to new railcars at a point in time when the customer has submitted its certificate of acceptance and legal title of the railcar has passed to the customer. Certain contracts for the sales of railcars include price adjustments based on changes to input costs; this amount represents variable consideration for which we are generally unable to estimate the final consideration until the railcar is delivered.
Revenue related to sustainable railcar conversions is recognized over time as sustainable railcar conversions are completed, using an input approach based on the costs incurred relative to the total estimated costs of performing the project. Revenue related to certain support services is recognized over time based on our stand-ready obligation to provide such services. We recorded contract assets of $4.6 million and $3.4 million as of September 30, 2025 and December 31, 2024, respectively. These contract assets are included within the Receivables, net of allowance line in our Consolidated Balance Sheets.
We account for shipping and handling costs as activities to fulfill the promise to transfer the good; as such, these fees are recorded in revenue. The fees and costs of shipping and handling activities are accrued when the related performance obligation has been satisfied.
Unsatisfied Performance Obligations
The following table includes estimated revenue expected to be recognized in future periods related to performance obligations that are unsatisfied or partially satisfied as of September 30, 2025 and the percentage of the outstanding performance obligations as of September 30, 2025 expected to be delivered during the remainder of 2025:

| Unsatisfied performance obligations at September 30, 2025

Table of Contents
The remainder of the unsatisfied performance obligations for the Rail Products Group is expected to be delivered through 2028. The orders in the Rail Products Group's backlog from the Leasing Group are fully supported by lease commitments with external customers. The final amount of backlog attributable to the Leasing Group may vary by the time of delivery as customers may elect to modify their procurement decision.
Unsatisfied performance obligations for the Railcar Leasing and Services Group are related to servicing, maintenance, and management agreements and are expected to be performed through 2029.
Lease Accounting
Lessor
Our Leasing Group enters into railcar operating leases with third parties with terms generally ranging between one year and ten years. The majority of our fleet operates on full-service leases that earn fixed monthly lease payments. Generally, lease payments are due at the beginning of the applicable month. A portion of our fleet operates on per diem leases that earn usage-based variable lease payments. Some of our leases include options to extend the leases for up to five years, and a small percentage of our leases include early termination options with certain notice requirements and early termination penalties. As of September 30, 2025, non-lease fleet operating leases in which we are the lessor were not significant, and we had no direct finance leases.
We manage risks associated with residual values of leased railcars by investing across a diverse portfolio of railcar types, staggering lease maturities within any given railcar type, avoiding concentration of railcar type and industry, and actively participating in secondary markets. Additionally, our lease agreements contain normal wear and tear return condition provisions and high mileage thresholds designed to protect the value of our residual assets. Our lease agreements do not contain any material residual value guarantees or restrictive covenants.
The following table summarizes the impact of our leases on our Consolidated Statements of Operations:

Financial Instruments
We consider all highly liquid debt instruments to be either cash and cash equivalents if purchased with a maturity of three months or less, or short-term marketable securities if purchased with a maturity of more than three months and less than one year.
Financial instruments that potentially subject us to a concentration of credit risk are primarily cash investments, including restricted cash and receivables. We place our cash investments in bank deposits, investment grade short-term debt instruments, highly-rated money market funds, and highly-rated commercial paper. We limit the amount of credit exposure to any one commercial issuer. The carrying values of cash, receivables, and accounts payable are considered to be representative of their respective fair values.
Concentrations of credit risk with respect to receivables are limited due to control procedures that monitor the credit worthiness of customers, the large number of customers in our customer base, and their dispersion across different end markets and geographic areas. Receivables are generally evaluated at a portfolio level based on these characteristics. As receivables are generally unsecured, we maintain an allowance for credit losses using a forward-looking approach based on historical losses and consideration of current and expected future economic conditions. Historically, we have observed that the likelihood of loss increases when receivables have aged beyond 180 days. When a receivable is deemed uncollectible, the write-off is recorded as a reduction to the allowance for credit losses. During the nine months ended September 30, 2025, we recognized approximately $3.4 million of credit loss expense and wrote off $0.8 million related to our trade receivables that are in the scope of ASC 326, Financial Instruments – Credit Losses, bringing the allowance for credit losses balance from $14.3 million at December 31, 2024 to $16.9 million at September 30, 2025. This balance excludes the general reserve for operating lease receivables that is permitted under ASC 450, Contingencies.
Supply Chain Finance Program
In cooperation with a participating financial institution, we facilitate a voluntary supply chain finance ("SCF") program for several of our suppliers. We negotiate payment terms with suppliers that are in line with average industry terms. We have not pledged any assets as security or provided other forms of guarantees to the financial institution. Under the SCF program, participating suppliers may choose to sell, at a discounted price, receivables due from us to the financial institution, at the sole discretion of both the suppliers and the financial institution, prior to the invoices’ scheduled due dates. The payment terms that we negotiate with all suppliers are consistent regardless of whether the supplier chooses to participate in the SCF program for a particular invoice. The SCF program is administered by a third-party financial institution, and our responsibility is limited to making payments based on the terms originally negotiated with participating suppliers, regardless of whether such suppliers sell receivables to the financial institution.
Amounts due to our participating suppliers in the SCF program totaled $32.8 million and $8.2 million as of September 30, 2025 and December 31, 2024, respectively, and are included in accounts payable in our Consolidated Balance Sheets. Payments made under the SCF program are reflected in net cash provided by operating activities from continuing operations in our Consolidated Statements of Cash Flows.

Recent Accounting Pronouncements
Not Yet Adopted
ASU 2023-09 – In December 2023, the FASB issued ASU No. 2023-09, "Improvements to Income Tax Disclosures," which enhances transparency and decision usefulness of income tax disclosures. ASU 2023-09 requires, on an annual basis, a tabular disclosure using specific categories in the rate reconciliation and providing additional information for reconciling items that meet a quantitative threshold, as well as the disaggregation of income taxes paid by federal, state, and foreign jurisdictions. ASU 2023-09 is effective for public companies during annual reporting periods beginning after December 15, 2024 on a prospective basis, with an option for retrospective application. We are currently evaluating the impact ASU 2023-09 will have on our income tax disclosures.
ASU 2024-03 – In November 2024, the FASB issued ASU No. 2024-03, "Disaggregation of Income Statement Expenses," which improves financial reporting and responds to investor input by requiring public companies to disclose additional information about certain expenses in the notes to the consolidated financial statements. ASU 2024-03 requires disclosures, on an annual and interim basis, of the amounts of purchases of inventory, employee compensation, depreciation, and intangible asset amortization included in each relevant expense category; a qualitative description of amounts remaining that are not separately disaggregated quantitatively; and the amount of selling expenses and, in annual reporting periods, the definition of selling expenses. ASU 2024-03 is effective for public companies during annual reporting periods beginning after December 15, 2026 on a prospective basis, with an option for retrospective application. Early adoption is permitted. We are currently evaluating the impact ASU 2024-03 will have on our financial statement disclosures.
Note 2. Acquisitions and Discontinued Operations
Acquisitions
Acquisition of Holden America
In December 2022, we acquired Holden America, a manufacturer of market-leading multi-level vehicle securement and protection systems, gravity-outlet gates, and gate accessories for freight rail in North America. The purchase agreement included minimum additional consideration of $10.0 million, which was payable in installments of $5.0 million per year in each of 2024 and 2025. The purchase agreement also contained a provision whereby additional consideration could become payable based on the achievement of certain revenue targets, up to a maximum payout of $10.0 million. The first installment of the additional consideration, totaling $10.0 million, was paid during the nine months ended September 30, 2024.
During the nine months ended September 30, 2025, the second and final installment of the additional consideration, totaling $10.0 million, was paid. This payment is reflected in our Consolidated Statements of Cash Flows, of which $8.0 million related to the initial estimated fair value is included in financing activities, and $2.0 million related to the remeasurement of the initial estimated fair value is included in operating activities.
Discontinued Operations
In the fourth quarter of 2021, we completed the sale of Trinity Highway Products, LLC (“THP”). Upon completion of the sale, the accounting requirements for reporting THP as a discontinued operation were met. In connection with the sale, the Company agreed to indemnify the buyer for certain liabilities related to the highway products business, including certain liabilities resulting from or arising out of the ET-Plus® System, a highway guardrail end-terminal system (the “ET Plus”). Consequently, results from discontinued operations include certain legal expenses that are directly attributable to the highway products business. Similar expenses related to these retained obligations that may be incurred in the future will likewise be reported in discontinued operations. For the three and nine months ended September 30, 2025, we recorded expenses related to these obligations of $2.2 million ($1.1 million, net of income taxes) and $7.1 million ($4.9 million, net of income taxes), respectively. For the three and nine months ended September 30, 2024, we recorded expenses related to these obligations of $7.0 million ($5.3 million, net of income taxes) and $14.8 million ($11.3 million, net of income taxes), respectively. These expenses are included in loss from discontinued operations, net of income taxes in our Consolidated Statements of Operations. See Note 15 of our Annual Report on Form 10-K for further information regarding obligations retained in connection with the THP sale.

Note 3. Derivative Instruments and Fair Value Measurements
Derivative Instruments
We use derivative instruments to mitigate interest rate risk, including risks associated with the impact of changes in interest rates in anticipation of future debt issuances and to offset interest rate variability of certain floating rate debt issuances outstanding. We also use derivative instruments to mitigate the impact of changes in foreign currency exchange rates. Derivative instruments that are designated and qualify as cash flow hedges are accounted for by recording the effective portion of the gain or loss on the derivative instrument in accumulated other comprehensive income or loss ("AOCI") as a separate component of stockholders' equity. These accumulated gains or losses are reclassified into earnings in the periods during which the hedged transactions affect earnings. Derivative instruments that are not designated as hedges are accounted for by recording the realized and unrealized gains or losses on the derivative instrument in other, net (income) expense in our Consolidated Statements of Operations. We continuously monitor our derivative positions and the credit ratings of our counterparties and do not anticipate losses due to non-performance. See Note 8 for a description of our debt instruments.

See Note 8 for further information. The swaps had a $6.7 million derivative liability fair value upon termination. In lieu of cash settlement, we incorporated the $6.7 million derivative liability into the terms of the new interest rate swaps, as described in the footnote below, resulting in off-market terms.
(3) In April 2025, we entered into interest rate swaps associated with the amended and restated TRL-2023 term loan agreement. The swaps had a $6.7 million derivative liability fair value at inception, representing the off-market component of the swaps. The off-market value is being ratably amortized into interest expense through the maturity date of the swaps related to the amended and restated TRL-2023 term loan.
(4) We entered into a forward starting interest rate swap to hedge a portion of the risk of potential interest rate increases in anticipation of a debt issuance, which was completed in October 2025. See Note 8 for further information.

Fair Value Measurements
Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for that asset or liability in an orderly transaction between market participants on the measurement date. An entity is required to establish a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. The three levels of inputs that may be used to measure fair value are listed below.
Level 1 – This level is defined as quoted prices in active markets for identical assets or liabilities. Our cash equivalents and restricted cash are instruments of the U.S. Treasury or highly-rated money market mutual funds. The assets measured on a recurring basis as Level 1 in the fair value hierarchy are summarized below:

| Level 1
| September 30, 2025 |  | December 31, 2024
| (in millions)
Assets: |  |  |
Cash equivalents | $ | 43.2 |  |  | $ | 209.6 |
Restricted cash | 172.4 |  |  | 146.2 |
Total assets | $ | 215.6 |  |  | $ | 355.8 |

Level 2 – This level is defined as observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Interest rate swaps and interest rate caps are valued at exit prices obtained from each counterparty. Foreign currency hedges are valued at exit prices obtained from each counterparty, which are based on currency spot and forward rates and forward points. The assets and liabilities measured on a recurring basis as Level 2 in the fair value hierarchy are summarized below:

| Level 2 |

Total liabilities | $ | 17.8 |  |  | $ | 32.8 |  |

(1) Included in other assets in our Consolidated Balance Sheets.
(2) Included in accrued liabilities in our Consolidated Balance Sheets.
Level 3 – This level is defined as unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. As of September 30, 2025 and December 31, 2024, we have no assets or liabilities measured on a recurring basis as Level 3 in the fair value hierarchy.
See Note 8 for the estimated fair values of our debt instruments. The fair values of all other financial instruments are estimated to approximate carrying value.

Note 4. Segment Information
We report our operating results in two reportable segments: (1) the Railcar Leasing and Services Group, which owns and operates a fleet of railcars and provides third-party fleet leasing, management, and administrative services; railcar maintenance and modification services; and other railcar logistics products and services; and (2) the Rail Products Group, which manufactures and sells railcars and related parts and components.
Our Chief Operating Decision Maker ("CODM") is our Chief Executive Officer. Operating profit is the primary measure our CODM uses to assess performance and allocate resources to each of our reportable segments. Gains and losses from the sale of property, plant, and equipment are included in the operating profit of each respective segment.
Sales and related net profits ("deferred profit") from the Rail Products Group to the Leasing Group are recorded in the Rail Products Group and eliminated in consolidation. Sales between these groups are recorded at prices comparable to those charged to external customers, taking into consideration quantity, features, and production demand. Amortization of deferred profit on railcars sold to the Leasing Group is included in the operating profit of the Leasing Group, resulting in the recognition of depreciation expense based on our original manufacturing cost of the railcars. Lease portfolio sales are included in the Leasing Group, with related gains and losses computed based on the net book value of the original manufacturing cost of the railcars.
The financial information for these segments is shown in the tables below (in millions). We operate principally in North America.

Note 5. Partially-Owned Subsidiaries
Investments in Leasing Subsidiaries
Through our wholly-owned subsidiary, TILC, we formed two subsidiaries, TRIP Holdings and RIV 2013, for the purpose of providing railcar leasing services in North America for institutional investors. Each of TRIP Holdings and RIV 2013 are direct, partially-owned subsidiaries of TILC in which we have a controlling interest. Each is governed by a seven-member board of representatives, two of whom are designated by TILC. TILC is the agent of each of TRIP Holdings and RIV 2013 and, as such, has been delegated the authority, power, and discretion to take certain actions on behalf of the respective companies.
At September 30, 2025, the carrying value of our investments in TRIP Holdings and RIV 2013 totaled $131.4 million. Our ownership interests in TRIP Holdings and RIV 2013 are 42.6% and 30.5%, respectively, with the remaining interests owned by third-party, investor-owned funds. These investments in our partially-owned leasing subsidiaries are eliminated in consolidation.
Each of TRIP Holdings and RIV 2013 has wholly-owned subsidiaries that are the owners of railcars acquired from our Rail Products and Leasing Groups. TRIP Holdings has wholly-owned subsidiaries known as Triumph Rail LLC ("Triumph Rail") and Tribute Rail LLC ("Tribute Rail"). RIV 2013 has a wholly-owned subsidiary known as TRP 2021 LLC ("TRP-2021"). TILC is the contractual servicer for Triumph Rail, Tribute Rail, and TRP-2021, with the authority to manage and service each entity's owned railcars. Our controlling interest in each of TRIP Holdings and RIV 2013 results from our combined role as both equity member and agent/servicer. The noncontrolling interest included in the accompanying Consolidated Balance Sheets primarily represents the non-Trinity equity interest in these partially-owned subsidiaries.
19

Table of Contents
Trinity has no obligation to guarantee performance under any of our partially-owned subsidiaries' (or their respective subsidiaries') debt agreements, guarantee any railcar residual values, shield any parties from losses or guarantee minimum yields.
The assets of each of Triumph Rail, Tribute Rail, and TRP-2021 may only be used to satisfy the particular subsidiary's liabilities, and the creditors of each of Triumph Rail, Tribute Rail, and TRP-2021 have recourse only to the particular subsidiary's assets. Each of TILC and the third-party equity investors receive distributions from TRIP Holdings and RIV 2013, when available, in proportion to its respective equity interests, and has an interest in the net assets of the partially-owned subsidiaries upon a liquidation event in the same proportion. TILC is paid fees for the services it provides to Triumph Rail, Tribute Rail, and TRP-2021 and has the potential to earn certain incentive fees. There are no remaining equity commitments with respect to TRIP Holdings or RIV 2013.
See Note 8 for additional information regarding the debt of TRIP Holdings and RIV 2013 and their respective subsidiaries.
Other Investment in Consolidated Affiliate
In 2023, the Company and a third party formed Trinity Global Ventures to deliver railcars and provide warranty support services in Saudi Arabia. Trinity Global Ventures is owned 51.0% by Trinity Rail Group, LLC ("Trinity Rail Group"), a wholly-owned subsidiary of the Company, and 49.0% by the third party. Upon consideration under the variable interest entity (“VIE”) model of ASC 810, Consolidation, Trinity has concluded that Trinity Global Ventures meets the definition of a VIE. Trinity Rail Group has a variable interest in Trinity Global Ventures arising from its 51.0% equity ownership position. We determined that Trinity is the primary beneficiary and therefore consolidates this entity as we have the power to direct the activities of the entity that most significantly impact its economic performance. At September 30, 2025, the carrying value of our investment in Trinity Global Ventures totaled $2.7 million, which is eliminated in consolidation.
Investment in Unconsolidated Affiliate
In 2021, the Company and Wafra, Inc. (“Wafra”), a global alternative investment manager, entered into a railcar investment vehicle program between Trinity and certain funds managed by Wafra (“Wafra Funds”). As part of this program, a joint venture was formed, Signal Rail Holdings LLC (“Signal Rail”), which is currently owned 87.4% by Wafra Funds and 12.6% by TILC. TILC services all railcars owned by Signal Rail.
Upon consideration under the VIE model of ASC 810, Consolidation, Trinity has concluded that Signal Rail meets the definition of a VIE. TILC has variable interests in Signal Rail arising from its 12.6% equity ownership position and its role as a service provider. We determined that Trinity is not the primary beneficiary and therefore does not consolidate this entity as we do not have the power to direct the activities of the entity that most significantly impact its economic performance. We will absorb portions of Signal Rail’s expected losses and/or receive portions of expected residual returns commensurate with our 12.6% equity interest in Signal Rail.
Our investment in Signal Rail is being accounted for under the equity method of accounting. At September 30, 2025, the carrying value of TILC’s equity investment in Signal Rail was $20.1 million, which is included in other assets in our Consolidated Balance Sheets. The carrying value of this investment represents our maximum exposure in Signal Rail.

Estimated Fair Value of Debt – The estimated fair value of our 7.75% senior notes due 2028 ("Senior Notes due 2028") is based on a quoted market price in a market with little activity (Level 2 input). The estimated fair values of our secured railcar equipment notes are based on our estimate of their fair value using unobservable input values provided by a third party (Level 3 inputs). The respective carrying values of our revolving credit facility, 2017 promissory notes, TRL-2023 term loan, and TILC warehouse facility approximate fair value because the interest rate adjusts to the market interest rate. As of September 30, 2025, we evaluated the fair value of the other equipment financing liability using Level 3 inputs and determined that the carrying value approximates fair value. The estimated fair values of our debt are as follows:

| September 30, 2025 |  | December 31, 2024
| (in millions)
Level 2 | $ | 621.6 |  |  | $ | 623.2 |
Level 3 | $ | 3,352.3 |  |  | $ | 3,430.5 |

Revolving Credit Facility – We have a $600.0 million unsecured corporate revolving credit facility. During the nine months ended September 30, 2025, there were total borrowings of $230.0 million and total repayments of $140.0 million under the revolving credit facility. Additionally, we had outstanding letters of credit issued in an aggregate amount of $7.3 million, leaving $502.7 million available for borrowing as of September 30, 2025. Our outstanding letters of credit as of September 30, 2025 support performance bonds related to certain railcar orders. The revolving credit facility bears interest at a variable rate of SOFR plus (1) a benchmark adjustment of 10 basis points and (2) a facility margin of 1.50%, for an all-in interest rate of 5.78% as of September 30, 2025. A commitment fee accrues on the average daily unused portion of the revolving credit facility at the rate of 0.175% to 0.40% (0.20% as of September 30, 2025).

Table of Contents
The revolving credit facility requires the maintenance of ratios related to minimum interest coverage for the leasing and manufacturing operations and maximum leverage. As of September 30, 2025, we were in compliance with all such financial covenants.
TILC Warehouse Loan Facility – TILC has a $800.0 million warehouse loan facility to finance railcars owned by TILC. During the nine months ended September 30, 2025, we had total borrowings of $329.5 million and total repayments of $116.5 million under the TILC warehouse loan facility. The entire unused facility amount of $2.4 million was available as of September 30, 2025 based on the amount of warehouse-eligible, unpledged equipment. Advances under the facility bear interest at one-month term SOFR plus a facility margin of 1.75%, for an all-in interest rate of 6.03% at September 30, 2025.
TRL-2023 Term Loan – In April 2025, TRL-2023, a limited purpose, indirect wholly-owned subsidiary of the Company owned through TILC, entered into an amended and restated term loan agreement (the “TRL-2023 term loan agreement”) to (i) increase the aggregate amount of the term loan from $320.7 million as of March 31, 2025 to $1.05 billion; (ii) extend the maturity date to April 30, 2030; and (iii) reduce the applicable interest rate to daily simple SOFR plus a facility margin of 1.50%. We incurred $5.6 million in debt issuance costs, which will be amortized to interest expense over the term of the TRL-2023 term loan. The TRL-2023 term loan is an obligation of TRL-2023 and is non-recourse to Trinity. The obligation is secured by a portfolio of railcars and operating leases thereon, certain cash reserves, and other assets owned by TRL-2023. Net proceeds received from the transaction were used to redeem in full the outstanding borrowings of approximately $616.0 million under TRL-2017, as described below; to repay approximately $75.8 million of borrowings under TILC's warehouse loan facility; and for general corporate purposes.
Redemption of TRL-2017 Promissory Notes – In April 2025, with the net proceeds of the TRL-2023 term loan agreement described above, we redeemed in full the TRL-2017 promissory notes (the "2017 Promissory Notes"), of which $616.0 million was outstanding at the redemption date. The interest rate for the 2017 Promissory Notes was at one-month term SOFR plus (1) a benchmark adjustment of 11 basis points and (2) a facility margin of 1.50%. In connection with the redemption of the 2017 Promissory Notes, during the nine months ended September 30, 2025, we recognized a loss on extinguishment of debt of $0.8 million, which included the write-off of unamortized debt issuance costs and other direct costs associated with the extinguishment. This charge is reflected in the interest expense, net line of our Consolidated Statements of Operations.
Subsequent Events
TRL-2025 Secured Railcar Equipment Notes – On October 28, 2025, Trinity Rail Leasing 2025 LLC, a Delaware limited liability company ("TRL-2025") and a limited purpose, indirect wholly-owned subsidiary of the Company owned through TILC, issued an aggregate principal amount of (i) $498.6 million of its Series 2025-1 Class A Green Secured Railcar Equipment Notes (the "TRL-2025 Class A Notes"), and (ii) $36.6 million of its Series 2025-1 Class B Green Secured Railcar Equipment Notes (the "TRL-2025 Class B Notes") (the TRL-2025 Class A Notes and the TRL-2025 Class B Notes are, collectively, the “TRL-2025 Notes”). The TRL-2025 Class A Notes bear interest at a fixed rate of 5.09%, and the TRL-2025 Class B Notes bear interest at a fixed rate of 5.30%. The TRL-2025 Notes are payable monthly, and have a stated final maturity date of October 19, 2055. The TRL-2025 Notes are obligations of TRL-2025 and are non-recourse to Trinity. The obligations are secured by a portfolio of railcars and operating leases thereon, certain cash reserves, and other assets acquired and owned by TRL-2025. TRL-2025 purchased a portfolio of railcars directly from TILC and from TILC's affiliates, Trinity Rail Leasing Warehouse Trust, and Trinity Rail Leasing 2010 LLC ("TRL-2010"). Net proceeds received from the railcars acquired in connection with the issuance of the TRL-2025 Notes were used to repay approximately $259.0 million of borrowings under TILC's warehouse loan facility; to redeem the outstanding debt of TRL-2010, as described below; and for general corporate purposes.
Redemption of TRL-2010 Secured Railcar Equipment Notes – On October 28, 2025, with the net proceeds of the TRL-2025 Notes described above, we redeemed in full the TRL-2010 secured railcar equipment notes (the "TRL-2010 Notes"), of which $133.8 million was outstanding at the redemption date. The all-in interest rate for the TRL-2010 Notes was 5.19% per annum.
Terms and conditions of our other debt, including recourse and non-recourse provisions and scheduled maturities, are described in Note 9 of our 2024 Annual Report on Form 10-K.

Note 9. Income Taxes
The effective tax rate from continuing operations for the three months ended September 30, 2025 was an expense of 23.0%, which differs from the U.S. statutory rate of 21.0% primarily due to state income taxes, foreign income taxes, and other permanent differences, partially offset by the benefit of noncontrolling interest for which we do not provide income taxes.
The effective tax rate from continuing operations for the nine months ended September 30, 2025 was an expense of 20.4%, which differs from the U.S. statutory rate of 21.0% primarily due to the benefit of noncontrolling interest for which we do not provide income taxes and the benefit of tax credits purchased at a discount, partially offset by state income taxes, foreign income taxes, and other permanent differences.
The effective tax rates from continuing operations for the three and nine months ended September 30, 2024 were expenses of 27.7% and 25.1%, respectively, which differ from the U.S. statutory rate of 21.0% primarily due to state income taxes, foreign income taxes, non-deductible executive compensation, and return to provision adjustments, partially offset by the benefit of noncontrolling interest for which we do not provide income taxes, excess tax benefits associated with equity-based compensation, and changes in state tax laws.
Deferred income taxes related to railcars in our lease fleet were $1.2 billion and $1.1 billion as of September 30, 2025 and December 31, 2024, respectively.
The Inflation Reduction Act of 2022 allows a company to purchase transferable tax credits. During the nine months ended September 30, 2025, we purchased $40.0 million in tax credits for approximately $38.4 million in cash. These credits were used to offset the Company’s federal income tax liability for 2024, which resulted in the recognition of a tax benefit of $1.6 million for the nine months ended September 30, 2025.
On July 4, 2025, the One Big Beautiful Bill Act (the "Act") was enacted. The Act includes multiple business tax provisions, including the reinstatement of 100% bonus depreciation and a change in the calculation of deductible interest expense. These changes were incorporated into our provision for income taxes for the three and nine months ended September 30, 2025, resulting in an increase to our deferred tax expense, offset by a corresponding decrease to our current tax expense. The Act did not have a material impact on our total income tax expense or our effective tax rates for the three and nine months ended September 30, 2025.
Note 10. Accumulated Other Comprehensive Income (Loss)
Changes in AOCI for the nine months ended September 30, 2025 are as follows:

| Unrealized gains/(losses) on derivative financial instruments |  | Net actuarial gains/(losses) of defined benefit plans |  | Accumulated other comprehensive income (loss)
Balances at December 31, 2024 | $ | (3.0) |  |  | $ | (1.2) |  |  | $ | (4.2) |
Other comprehensive income, net of tax, before reclassifications | 1.7 |  |  | — |  |  | 1.7 |
Amounts reclassified from AOCI, net of tax expense of $0.5, $—, and $0.5 | (1.3) |  |  | 0.1 |  |  | (1.2) |
Less: noncontrolling interest | (0.2) |  |  | — |  |  | (0.2) |
Other comprehensive income | 0.2 |  |  | 0.1 |  |  | 0.3 |
Balances at September 30, 2025 | $ | (2.8) |  |  | $ | (1.1) |  |  | $ | (3.9) |

See Note 3 for additional information on the reclassification of amounts in AOCI into earnings. Reclassifications of unrealized before-tax gains and losses on derivative financial instruments are included in interest expense, net for our interest rate hedges and in cost of revenues for our foreign currency hedges in our Consolidated Statements of Operations. Reclassifications of before-tax net actuarial gains/(losses) of defined benefit plans are included in other, net (income) expense in our Consolidated Statements of Operations.

Note 11. Stock-Based Compensation
Stock-based compensation expense totaled approximately $5.9 million and $16.6 million for the three and nine months ended September 30, 2025, respectively. Stock-based compensation expense totaled approximately $6.7 million and $17.3 million for the three and nine months ended September 30, 2024, respectively. The Company's annual grants of share-based awards generally occur in the first and second quarters under our Fifth Amended and Restated Stock Option and Incentive Plan.
The following table summarizes stock-based compensation awards granted during the nine months ended September 30, 2025:

| Number of Shares Granted |  | Weighted Average Grant-Date Fair Value per Award
Restricted stock units | 456,552 |  |  | $ | 26.96 |
Restricted stock awards | 28,388 |  |  | $ | 26.95 |
Performance units | 225,192 |  |  | $ | 32.73 |

The fair value of restricted stock units and restricted stock awards ("RSAs") granted is based on the Company's closing stock price on the date of grant. For the performance units granted during the nine months ended September 30, 2025 for which the payout is based on relative total shareholder return, the fair value was estimated at the date of grant using a Monte Carlo simulation with assumptions that reflect market conditions at the date of grant, including stock price, risk-free interest rate, expected term, expected volatility, and dividend yield. For the performance units granted during the nine months ended September 30, 2025 for which the payout is based on return on equity, the fair value is based on the Company's closing stock price on the date of grant, adjusted to exclude the cumulative value of dividends over the three-year vesting period as these units do not earn dividend equivalents.

Note 12. Earnings Per Common Share
Basic net income attributable to Trinity Industries, Inc. per common share ("EPS") is computed by dividing net income attributable to Trinity by the weighted average number of basic common shares outstanding for the period. Except when the effect would be antidilutive, the calculation of diluted EPS includes the net impact of potentially dilutive common shares. The Company has certain unvested RSAs that participate in dividends on a nonforfeitable basis and are therefore considered to be participating securities. Consequently, diluted net income attributable to Trinity Industries, Inc. per common share is calculated under both the two-class method and the treasury stock method, and the more dilutive of the two calculations is presented.
The following table sets forth the computation of basic and diluted net income attributable to Trinity Industries, Inc.:

Note 13. Contingencies
East Palestine, OH Train Derailment
As previously disclosed, on February 3, 2023, a Norfolk Southern Railway freight train derailed 38 railcars in East Palestine, Ohio. TILC has been named in various actions associated with this incident, including Gregory Taylor, et al. v. Norfolk Southern Railway Co., et al., Case No. 2025 CV 00434, in the Court of Common Pleas, Columbiana County, Ohio; Josh Hickman, et al. v. Norfolk Southern Railway Co., et al., Case No. 2025 CV 00434, in the Court of Common Pleas, Columbiana County, Ohio; and Richard Tsai, et al. v. Norfolk Southern Corporation, et al., Case No. 250200415, in the Court of Common Pleas, Philadelphia County, Pennsylvania. TILC was the owner of one tank car cited in these actions, which was leased to a third party, who is also a defendant in these matters. There have been no significant developments in such proceedings since the filing of our Quarterly Report on Form 10-Q filed July 31, 2025.
The Company believes it has substantial defenses and intends to vigorously defend itself against all allegations in the third-party and direct claims asserted against TILC. The Company or its subsidiaries could be named in similar litigation involving other plaintiffs, but the ultimate number of claims and the jurisdiction(s) in which such claims, if any, may be filed may vary. We do not believe at this time that a loss is probable in these matters, nor can a range of possible losses be determined. Accordingly, no accrual or range of loss has been included in the accompanying Consolidated Financial Statements. The Company maintains liability insurance coverage and commercial contractual indemnity rights to protect the Company’s assets from losses arising from these types of litigation claims.
Highway products litigation
Pursuant to the purchase and sale agreement related to the sale of THP, the Company agreed to indemnify the buyer for certain liabilities related to the highway products business, including those liabilities resulting from or arising out of ET Plus systems or specified ET Plus component parts that are both (i) manufactured prior to December 31, 2021, and (ii) sold in the United States on or prior to April 30, 2022, or related warranty obligations with respect thereto. There have been no significant developments in such proceedings since those previously described in Note 15 of our 2024 Annual Report on Form 10-K.
Other matters
The Company is involved in claims and lawsuits incidental to our business arising from various matters, including product warranty, personal injury, environmental issues, workplace laws, and various governmental regulations. The Company evaluates its exposure to such claims and suits periodically and establishes accruals for these contingencies when a range of loss can be reasonably estimated. The range of reasonably possible losses for such matters is $7.4 million to $18.7 million. At September 30, 2025, total accruals of $8.8 million, including environmental and workplace matters described below, are included in accrued liabilities in the accompanying Consolidated Balance Sheets. The Company believes any additional liability would not be material to its financial position or results of operations.
Trinity is subject to remedial orders and federal, state, local, and foreign laws and regulations relating to the environment and the workplace. The Company has reserved $1.1 million to cover our probable and estimable liabilities with respect to the investigations, assessments, and remedial responses to such matters, taking into account currently available information and our contractual rights to indemnification and recourse to third parties. However, estimates of liability arising from future proceedings, assessments, or remediation are inherently imprecise. Accordingly, there can be no assurance that we will not become involved in future litigation or other proceedings involving the environment and the workplace or, if we are found to be responsible or liable in any such litigation or proceeding, that such costs would not be material to the Company. We believe that we are currently in substantial compliance with environmental and workplace laws and regulations.

Company Overview
Trinity Industries, Inc. and its consolidated subsidiaries own businesses that are leading providers of railcar products and services in North America. We market our railcar products and services under the trade name TrinityRail®. Our platform also includes the brands of RSI Logistics, a provider of software and logistics solutions, and Holden America, a supplier of railcar parts and components. Our platform provides railcar leasing and management services; railcar manufacturing; railcar maintenance and modifications; and other railcar logistics products and services.
We report our operating results in two reportable segments: (1) the Railcar Leasing and Services Group (the "Leasing Group"), which owns and operates a fleet of railcars and provides third-party fleet leasing, management, and administrative services; railcar maintenance and modification services; and other railcar logistics products and services; and (2) the Rail Products Group, which manufactures and sells railcars and related parts and components.
Executive Summary
Cyclical, Seasonal and Other Trends Impacting Our Business
General Business Trends
Demand for many of our railcar products and services is correlated to changes in North American industrial production and international trade. We continue to actively monitor evolving tariff and trade developments and the potential impacts to our business. Uncertainty in these areas and in the macroeconomic environment, including the administration of trade policy, is negatively impacting and could continue to negatively impact our results of operations and demand for new railcars. We remain focused on mitigating impacts to our business resulting from these evolving developments.
The industries in which our customers operate are cyclical in nature. Although lease rates and lease fleet utilization remain strong, weaknesses in certain sectors of the North American and global economy may make it more difficult to sell or lease certain types of railcars. Additionally, changes in certain commodity prices, or changes in demand for certain commodities, could impact customer demand for various types of railcars. Further, disruptions in the global supply chain have impacted demand for, and the costs of, certain of our products and services.
We continuously assess demand for our products and services and take steps to rationalize and diversify our leased railcar portfolio and align our operating capacity appropriately. We evaluate the creditworthiness of our customers and monitor performance of relevant market sectors; however, weaknesses in any of these market sectors could affect the financial viability of our customers, which could negatively impact our revenues, credit loss expense, and operating profits. We continue to believe that our rail platform is able to respond to cyclical changes in demand and perform throughout the railcar cycle.
We believe that our leasing business provides a natural hedge against inflation and changes in interest rates; however, like many leasing companies, the debt component of our capital structure exposes us to changes in the interest rate environment. A significant portion of the earnings from our leasing business is derived from multi-year full-service leases. We consider changes in interest rates, inflation, and other relevant factors in the pricing of new and renewing leases; however, only a portion of our leased railcar portfolio is repriced each year. Consequently, our earnings could be impacted by timing differences between when interest rate changes and changes in the inflationary environment occur and when we are able to factor these changes into our lease rates.
Due to their transactional nature, lease portfolio sales are the primary driver of fluctuations in results in the Leasing Group.
Input Costs
We periodically experience volatility in the costs of steel, components, and certain other inputs that represent a substantial portion of our cost of revenues. We typically use contract-specific purchasing practices, existing supplier commitments, contractual price escalation provisions, and other arrangements with our customers to reduce the impact of the volatility of certain input costs on our operating profit. Further, the cost and volume of lease fleet maintenance and compliance events remain elevated, which we expect to continue in the near term. We continually assess the impact of input costs on our operational efficiency, margins, and overall profitability.

Table of Contents
Supply Chain and Transportation Network Disruptions
As a result of disruptions in the global supply chain, we have, from time to time, experienced shortages of materials used to manufacture or repair certain railcar types. We are also subject to disruptions in the rail transportation network, including potential rail traffic closures or congestion in Eagle Pass, Texas, the primary border crossing used for railcar deliveries from our manufacturing facilities in Mexico. We continuously monitor rail and truck traffic at the U.S.-Mexico border and continue to evaluate available alternatives for rail and truck transportation between Mexico and the U.S. Additionally, we actively monitor our supply chain and take appropriate steps within our control to mitigate the potential impacts on our production schedules and delivery timelines. However, challenges related to supply chain and transportation network disruptions could negatively impact our operations or our ability to timely deliver railcars to our customers.

Capital Structure Updates
TRL-2023 Term Loan – In April 2025, Trinity Rail Leasing 2023 LLC (“TRL-2023”), a limited purpose, indirect wholly-owned subsidiary of the Company owned through Trinity Industries Leasing Company (“TILC”), entered into an amended and restated term loan agreement to (i) increase the aggregate amount of the term loan from $320.7 million as of March 31, 2025 to $1.05 billion; (ii) extend the maturity date to April 30, 2030; and (iii) reduce the applicable interest rate to daily simple SOFR plus a facility margin of 1.50%. Net proceeds received from the transaction were used to redeem in full the outstanding borrowings of approximately $616.0 million under Trinity Rail Leasing 2017, LLC (“TRL-2017”); to repay approximately $75.8 million of borrowings under TILC's warehouse loan facility; and for general corporate purposes. The interest rate for the TRL-2017 promissory notes was at one-month term SOFR plus (1) a benchmark adjustment of 11 basis points and (2) a facility margin of 1.50%.
See Note 8 of the Consolidated Financial Statements for additional information regarding these debt transactions.

Subsequent Events
On October 28, 2025, Trinity Rail Leasing 2025 LLC, a Delaware limited liability company ("TRL-2025") and a limited purpose, indirect wholly-owned subsidiary of the Company owned through TILC, issued an aggregate principal amount of $535.2 million of its Series 2025-1 Green Secured Railcar Equipment Notes (the "TRL-2025 Notes"). The TRL-2025 Notes bear interest at an all-in interest rate of 5.11%, are payable monthly, and have a stated final maturity date of October 19, 2055. TRL-2025 purchased a portfolio of railcars directly from TILC and from TILC's affiliates, Trinity Rail Leasing Warehouse Trust, and Trinity Rail Leasing 2010 LLC ("TRL-2010"). Net proceeds received from the railcars acquired in connection with the issuance of the TRL-2025 Notes were used to repay approximately $259.0 million of borrowings under TILC's warehouse loan facility; to redeem the outstanding debt of TRL-2010; and for general corporate purposes. The all-in interest rate for the TRL-2010 secured railcar equipment notes was 5.19% per annum.

Income taxes – The effective tax rate from continuing operations for the three months ended September 30, 2025 was an expense of 23.0%, which differs from the U.S. statutory rate of 21.0% primarily due to state income taxes, foreign income taxes, and other permanent differences, partially offset by the benefit of noncontrolling interest for which we do not provide income taxes.
The effective tax rate from continuing operations for the nine months ended September 30, 2025 was an expense of 20.4%, which differs from the U.S. statutory rate of 21.0% primarily due to the benefit of noncontrolling interest for which we do not provide income taxes and the benefit of tax credits purchased at a discount, partially offset by state income taxes, foreign income taxes, and other permanent differences.

* Not meaningful
Selling, engineering, and administrative expenses for the three and nine months ended September 30, 2025 decreased by 29.0% and 17.6%, respectively, when compared to the prior year periods primarily from lower employee-related costs, including incentive-based compensation, and lower consulting costs. The decrease in selling, engineering, and administrative expenses for the nine months ended September 30, 2025 was partially offset by costs associated with workforce reductions. Total operating costs during the nine months ended September 30, 2025 were favorably impacted by gains associated with the disposition of non-operating facilities.

Liquidity and Capital Resources
Overview
We expect to finance future operating requirements with cash, cash equivalents, and short-term marketable securities; cash flows from operations; and short-term debt, long-term debt, and equity. Debt instruments that we have utilized include the TILC warehouse loan facility, senior notes, convertible subordinated notes, non-recourse asset-backed securities, non-recourse promissory notes and term loans, and our revolving credit facility.
As of September 30, 2025, we have total committed liquidity of $571.4 million. Our total available liquidity includes: $66.3 million of unrestricted cash and cash equivalents; $502.7 million unused and available under our revolving credit facility; and $2.4 million unused and available under the TILC warehouse loan facility based on the amount of warehouse-eligible, unpledged equipment. We believe we have access to adequate capital resources to fund operating requirements and are an active participant in the capital markets.
On July 4, 2025, the One Big Beautiful Bill Act (the "Act") was enacted. The Act includes multiple business tax provisions, including the reinstatement of 100% bonus depreciation and a change in the calculation of deductible interest expense. We expect a positive impact on our operating cash flows as a result of the expected refund of estimated tax payments previously made, as well as lower cash tax outlays in both the current and future years.
Liquidity Highlights
TRL-2023 Term Loan – In April 2025, TRL-2023 entered into an amended and restated term loan agreement to (i) increase the aggregate amount of the term loan from $320.7 million as of March 31, 2025 to $1.05 billion; (ii) extend the maturity date to April 30, 2030; and (iii) reduce the applicable interest rate to daily simple SOFR plus a facility margin of 1.50%. Net proceeds received from the transaction were used to redeem the outstanding borrowings of TRL-2017, to repay borrowings under TILC's warehouse loan facility, and for general corporate purposes.
Redemption of TRL-2017 Promissory Notes – In April 2025, we redeemed in full the TRL-2017 promissory notes, of which $616.0 million was outstanding at the redemption date. The interest rate for the TRL-2017 promissory notes was at one-month term SOFR plus (1) a benchmark adjustment of 11 basis points and (2) a facility margin of 1.50%.
See Note 8 of the Consolidated Financial Statements for additional information regarding these debt transactions.

Operating Activities. Net cash provided by operating activities from continuing operations for the nine months ended September 30, 2025 was $187.2 million compared to net cash provided by operating activities from continuing operations of $383.5 million for the nine months ended September 30, 2024. The changes in our operating assets and liabilities are as follows:

| Nine Months Ended September 30,
| 2025 |  | 2024
| (in millions)
(Increase) decrease in receivables, inventories, and other assets | $ | (14.9) |  |  | $ | 81.5 |

Changes in operating assets and liabilities | $ | (125.6) |  |  | $ | 49.9 |

The changes in our operating assets and liabilities resulted in a net use of $125.6 million for the nine months ended September 30, 2025, as compared to a net source of $49.9 million for the nine months ended September 30, 2024. The changes in operating assets and liabilities were impacted primarily by higher inventory balances and the purchase of tax credits for $38.4 million in the current year period, as well as payments of incentive-based compensation during the nine months ended September 30, 2025 that were accrued as of December 31, 2024.
Investing Activities. Net cash used in investing activities for the nine months ended September 30, 2025 was $398.4 million compared to $105.2 million of net cash used in investing activities for the nine months ended September 30, 2024. Significant investing activities are as follows:
•We made a net fleet investment of $387.4 million during the nine months ended September 30, 2025, compared to $86.5 million in the prior year period primarily due to the timing of lease portfolio sales and fleet additions. Our investment in the lease fleet primarily includes new railcar additions, sustainable railcar conversions, railcar modifications, and other betterments, net of deferred profit, as well as secondary market purchases; and is net of proceeds from lease portfolio sales.
Financing Activities. Net cash provided by financing activities during the nine months ended September 30, 2025 was $80.4 million compared to $169.7 million of net cash used in financing activities for the nine months ended September 30, 2024. Significant financing activities are as follows:
•During the nine months ended September 30, 2025, we had total borrowings of $1,284.1 million and total debt repayments of $1,039.2 million, for net proceeds of $244.9 million, to support our investment in the lease fleet and for general corporate purposes. During the nine months ended September 30, 2024, we had total repayments of $1,831.0 million and total borrowings of $1,762.4 million, for net repayments of $68.6 million, primarily from the redemption of corporate debt, partially offset by debt proceeds to support our investment in the lease fleet and for general corporate purposes.
•We paid $74.6 million and $70.1 million in dividends to our common stockholders during the nine months ended September 30, 2025 and 2024, respectively.
•During the nine months ended September 30, 2025, we repurchased common stock totaling $58.9 million, resulting in a remaining authorization to repurchase up to $169.8 million of our common stock under the share repurchase program as of September 30, 2025. Certain shares of stock repurchased during September 2025, totaling $0.3 million, were cash settled in October 2025 in accordance with normal settlement practices. During the nine months ended September 30, 2024, we repurchased common stock totaling $6.9 million under the share repurchase program.

Current Debt Obligations
The revolving credit facility contains several financial covenants that require the maintenance of ratios related to minimum interest coverage for the leasing and manufacturing operations and maximum leverage. A summary of our financial covenants is detailed below:

Ratio |  | Covenant |  | Actual at September 30, 2025
Maximum leverage (1) |  | No greater than 3.75 to 1.00 |  | 2.19
Minimum interest coverage (2) |  | No less than 2.25 to 1.00 |  | 5.77

(1) Defined as the ratio of consolidated total indebtedness to consolidated earnings before interest, taxes, depreciation and amortization ("EBITDA") for the Borrower and its restricted subsidiaries for the period of four consecutive quarters ending with September 30, 2025.
(2) Defined as the ratio of the difference of (A) consolidated EBITDA less (B) consolidated capital expenditures – operating and administrative to consolidated interest expense to the extent paid in cash, in each case for the Borrower and its restricted subsidiaries for the period of four consecutive quarters ending with September 30, 2025.
As of September 30, 2025, we were in compliance with all such financial covenants. Please refer to Note 8 of the Consolidated Financial Statements for a description of our current debt obligations.
Capital Expenditures
For the full year 2025, we anticipate a net fleet investment of between $250 million and $350 million. Capital expenditures related to operating and administrative activities, including supporting automation, technology, and modernization of our facilities and processes, are projected to range between $45 million and $55 million for the full year 2025.
Off Balance Sheet Arrangements
As of September 30, 2025, we had outstanding letters of credit issued under our revolving credit facility in an aggregate amount of $7.3 million, which support performance bonds related to certain railcar orders. See Note 8 of the Consolidated Financial Statements for further information about our corporate revolving credit facility. Additionally, we had a letter of credit issued outside our revolving credit facility for $8.5 million to satisfy a liquidity reserve requirement associated with our TILC warehouse loan facility, which renews by its terms each year.
Derivative Instruments
We use derivative instruments to mitigate interest rate risk, including risks associated with the impact of changes in interest rates in anticipation of future debt issuances and to offset interest rate variability of certain floating rate debt issuances outstanding. We also use derivative instruments to mitigate the impact of changes in foreign currency exchange rates. Derivative instruments are accounted for in accordance with applicable accounting standards. See Note 3 of the Consolidated Financial Statements for discussion of how we utilize our derivative instruments.

Non-GAAP Financial Measures
We have included financial measures compiled in accordance with GAAP and certain non-GAAP measures in this Quarterly Report on Form 10-Q to provide management and investors with additional information regarding our financial results. Non-GAAP measures should not be considered in isolation or as a substitute for our reported results prepared in accordance with GAAP and, as calculated, may not be comparable to other similarly titled measures for other companies. For each non-GAAP financial measure, we provide a reconciliation to the most comparable GAAP measure.
Cash Flow from Operations with Net Gains on Lease Portfolio Sales
Cash flow from operations with net gains on lease portfolio sales is a non-GAAP financial measure. We believe this measure is useful to both management and investors as it provides a relevant measure of liquidity and a useful basis for assessing the breadth of the cash flow generation capabilities across our operating platform, as well as our ability to fund our operations and repay our debt. This measure is defined as net cash provided by operating activities from continuing operations as computed in accordance with GAAP, plus net gains on lease portfolio sales and is reconciled to net cash provided by operating activities from continuing operations, the most directly comparable GAAP financial measure, in the following table.

| Nine Months Ended September 30,
| 2025 |  | 2024
| (in millions)
Net cash provided by operating activities – continuing operations | $ | 187.2 |  |  | $ | 383.5 |
Net gains on lease portfolio sales | 35.4 |  |  | 36.2 |
Cash flow from operations with net gains on lease portfolio sales | $ | 222.6 |  |  | $ | 419.7 |

Item 5. Other Information
TRL-2025 Secured Railcar Equipment Notes
On October 28, 2025, Trinity Rail Leasing 2025 LLC, a Delaware limited liability company (“TRL-2025”) and a limited purpose, indirect wholly-owned subsidiary of Trinity Industries, Inc. (the “Company”), owned by the Company through the Company's direct wholly-owned subsidiary Trinity Industries Leasing Company (“TILC”), issued an aggregate principal amount of $498,580,000 of TRL-2025’s Series 2025-1 Class A Secured Green Standard Railcar Equipment Notes (the “Class A Notes”) and an aggregate principal amount of $36,660,000 of TRL-2025’s Series 2025-1 Class B Secured Green Standard Railcar Equipment Notes (the “Class B Notes” and together with the Class A Notes, the ”Notes”). The Notes were issued pursuant to a Master Indenture, dated October 28, 2025 (the “Indenture”) among TRL-2025, U.S. Bank Trust Company, National Association, as indenture trustee, and U.S. Bank National Association, as securities intermediary. The Indenture is supplemented by a Series 2025-1 Supplement dated October 28, 2025 (the “Indenture Supplement”). The Class A Notes bear interest at a fixed rate of 5.09%, are payable monthly, and have a stated final maturity date of October 19, 2055. The Class B Notes bear interest at a fixed rate of 5.30%, are payable monthly, and have a stated final maturity date of October 19, 2055.
The Notes are obligations of TRL-2025 only. The Notes are secured by a portfolio of railcars and operating leases thereon acquired and owned by TRL-2025 (the “Railcar Portfolio”) and other assets of TRL-2025. The Notes were offered and sold in a private placement solely to qualified institutional buyers in reliance on Rule 144A of the Securities Act of 1933, as amended (the “Securities Act”), and to persons who are not U.S. persons in offers and sales that occur outside the United States in reliance on Regulation S under the Securities Act, pursuant to a note purchase agreement as described in the Company's Form 8-K filed October 20, 2025.
While the stated final maturity of the Notes is October 19, 2055, the cash flows from TRL-2025's assets will be applied, pursuant to the payment priorities of the Indenture, so as to amortize the Notes to achieve monthly targeted principal balances. If the cash flow assumptions used in determining the targeted balances are met, it is anticipated that the Notes will be repaid well in advance of their stated final maturity date. There can be no assurance, however, that such cash flow assumptions will be realized. In addition, the Notes may be subject to acceleration upon the occurrence of certain events of default under the Indenture, including a failure to pay interest on the Notes, and a failure of the Notes to amortize to the extent that, over time, the outstanding principal balance of the Notes were to eventually exceed the sum of the depreciated value of the Railcar Portfolio and the amounts on deposit in certain accounts of TRL-2025. The decision whether to accelerate or exercise other remedies against TRL-2025 and its assets will be under the control of holders representing a majority of the senior class of the outstanding principal balance of the Notes.
TRL-2025 purchased the Railcar Portfolio directly from TILC and from TILC’s affiliates, Trinity Rail Leasing Warehouse Trust (“TRLWT”) and Trinity Rail Leasing 2010 LLC (“TRL-2010”). Net proceeds received from the railcars acquired in connection with the issuance of the Notes will be used (i) to repay approximately $259.0 million of borrowings under TRLWT’s secured warehouse credit facility, (ii) to redeem an aggregate principal amount of $133.8 million of TRL-2010’s Secured Railcar Equipment Notes, Series 2010-1, and (iii) for general corporate purposes.
As noted above, the Notes are solely the obligations of TRL-2025. TILC has, however, entered into certain agreements relating to the transfer of the Railcar Portfolio to TRL-2025 and the management and servicing of TRL-2025's assets. These agreements contain certain representations, undertakings and indemnities customary for asset sellers and service providers in transactions of this type.
The foregoing description of the Indenture and the Indenture Supplement is a summary and is qualified in its entirety by the terms of the Indenture and the Indenture Supplement, copies of which are filed as Exhibit 10.1 and Exhibit 10.2, respectively, to this Quarterly Report on Form 10-Q and incorporated by reference herein.
Stock Trading Plan
During the three months ended September 30, 2025, none of our directors or executive officers informed the Company of the adoption or termination of a "Rule 10b5-1 trading arrangement" or a "non-Rule 10b5-1 trading arrangement", as those terms are defined in Item 408 of SEC Regulation S-K.
