**Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant**

On April 17, 2026, 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 (i) an aggregate principal amount of $447,439,000 of TRL-2025's Series 2026-1 Class A Secured Green Standard Railcar Notes (the "Class A Notes") and (ii) an aggregate principal amount of $33,360,000 of TRL-2025's Series 2026-1 Class B Secured Green Standard Railcar 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 2026-1 Supplement dated April 17, 2026 (the "Indenture Supplement").

The Class A Notes bear interest at a fixed rate of 5.35%, are payable monthly, and have a stated final maturity date of April 19, 2056. The Class B Notes bear interest at a fixed rate of 5.56%, are payable monthly, and have a stated final maturity date of April 19, 2056.

TRL-2025 previously issued (i) an aggregate principal amount of $498,580,000 of its Series 2025-1 Class A Secured Green Standard Railcar Equipment Notes (the "2025 Class A Notes") and (ii) an aggregate principal amount of $36,660,000 of its Series 2025-1 Class B Secured Green Standard Railcar Equipment Notes (the "2025 Class B Notes") (the 2025 Class A Notes and the 2025 Class B Notes are, collectively, the "Existing Notes") under the Indenture.

The Notes are obligations of TRL-2025 only. The Notes and the Existing Notes are secured by a portfolio of railcars and operating leases 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 April 6, 2026.

While the stated final maturity of the Notes is April 19, 2056, cash flow 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 together with the Existing 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 together with the Existing Notes.

TRL-2025 purchased the Railcar Portfolio directly, in multiple tranches, from TILC and from TILC's affiliates, Trinity Rail Leasing Warehouse Trust, Trinity Rail Leasing 2010 LLC, and Trinity Rail Leasing 2019 LLC ("TRL-2019"). Net proceeds received from the railcars acquired in connection with the issuance of the Notes will be used (i) to redeem an aggregate principal amount of $377,100,000 of TRL-2019's Series 2019-1 Secured Railcar Equipment Notes, and (ii) 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 Indenture was filed as Exhibit 10.1 to the Company's Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2025, and is incorporated by reference. A copy of the Indenture Supplement is attached as Exhibit 10.1 hereto and is incorporated by reference. The description of the Indenture and the Indenture Supplement contained herein does not purport to be complete and is qualified in its entirety by the full text of the relevant exhibit.

*Forward-Looking Statements*

*Some statements in this Current Report on Form 8-K, which are not historical facts, are "forward-looking statements" as defined by the Private Securities Litigation Reform Act of 1995. Forward-looking statements include statements about the Company's estimates, expectations, beliefs, intentions or strategies for the future, including the anticipated repayment of the Notes. The assumptions underlying these forward-looking statements include, but are not limited to, future financial and operating performance, future opportunities and any other statements regarding events or developments that the Company believes or anticipates will or may occur in the future. Forward-looking statements speak only as of the date hereof, and the Company expressly disclaims any obligation or undertaking to disseminate any updates or revisions to any forward-looking statement contained herein to reflect any change in the Company's expectations with regard thereto or any change in events, conditions or circumstances on which any such statement is based, except as required by federal securities laws. Forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from historical experience or our present expectations, including but not limited to risks and uncertainties regarding economic, competitive, governmental, and technological factors affecting the Company's operations, markets, products, services and prices, and such forward-looking statements are not guarantees of future performance. In particular, the repayment of the Notes is subject to general market and other conditions, which in turn are subject to a broad range of risks and uncertainties that could affect the Company, and there are no assurances that the Notes will be repaid when expected or at all. For a discussion of such risks and uncertainties, which could cause actual results to differ from those contained in the forward-looking statements, see "Risk Factors" and "Forward-Looking Statements" in the Company's Annual Report on Form 10-K for the most recent fiscal year, as may be revised and updated by the Company's Quarterly Reports on Form 10-Q, and the Company's Current Reports on Form 8-K.*

Any Class A Notes or Class B Notes of the Series 2026-1 Notes sold in reliance on Regulation S shall initially be represented by a Regulation S Temporary Book-Entry Note and shall be exchangeable for interests in the related Unrestricted Book-Entry Note.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp;The Series 2026-1 Notes shall be executed by manual or facsimile signature on behalf of the Issuer by a Responsible Officer and shall be substantially in the form of Exhibit A and Exhibit B, as the case may be, with the appropriate legend required by Section 2.02 of the Master Indenture inscribed on the face thereof.

**Section 2.04.** <u>Interest Payments on the Series 2026-1 Notes; Additional Interest</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;Interest on the Outstanding Principal Balance of each Series 2026-1 Note shall accrue during each Interest Accrual Period (i) at the Class A Note Interest Rate, in the case of the Class A Notes and (ii) at the Class B Note Interest Rate, in the case of the Class B Notes, and, in each case, will be calculated on the basis of a 360-day year consisting of twelve 30-day months and be due and payable in arrears on each Payment Date. Notwithstanding anything to the contrary in the Master Indenture or this Series 2026-1 Supplement, the initial Interest Accrual Period for the Series 2026-1 Notes shall begin on the Closing Date and end on (but exclude) May 19, 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;If any interest payment on any Class of the Series 2026-1 Notes is not timely paid in full when due, such overdue interest will bear interest at the applicable Stated Rate, payable as Additional Interest to the extent permitted by applicable law at the times and subject to the priorities set forth in the Flow of Funds. If a Rapid Amortization Event occurs with respect to a Class of Series 2026-1 Notes, the Issuer will also be required to pay the Noteholders of such Class of Series 2026-1 Notes, as part of, Additional Interest, interest on each Payment Date occurring on and after the Rapid Amortization Date in an amount equal to the Rapid Amortization Additional Interest Rate multiplied by the Outstanding Principal Balance of such Class of Series 2026-1 Notes (after giving effect to all payments on the relevant Class of Series 2026-1 Notes made on such day) (such interest, the "**Marginal Interest**") to the extent permitted by applicable law at the times and subject to the priorities set forth in the Flow of Funds. Such Marginal Interest due (if any) shall be (i) calculated on the basis of a 360-day year consisting of twelve 30-day months and (ii) due and payable in arrears on each Payment Date on or after the Rapid Amortization Date.

**Section 2.05.** <u>Principal Payments on the Series 2026-1 Notes</u>.

At any time that an Early Amortization Event or an Event of Default is then continuing, or if a Rapid Amortization Event with respect to the Series 2026-1 Notes has occurred, then, in addition to the foregoing, the Outstanding Principal Balance of the Series 2026-1 Notes shall be payable on each Payment

Date to the extent that amounts are available for such purpose in accordance with the Flow of Funds and Section 3.02 hereof.

**Section 2.06.** <u>Prepayment of Principal on the Series 2026-1 Notes</u>. (a) No Class A Optional Redemption may occur prior to the first anniversary of the Closing Date; provided, however, redemptions made in connection with any Involuntary Railcar Dispositions, Scrap Value Dispositions, Purchase Option Dispositions or Permitted Discretionary Sales in accordance with the terms of the Master Indenture will be permitted. Subject to the restrictions in Sections 3.12 and 3.13 of the Master Indenture, the Issuer will have the option to prepay, in an Optional Redemption on any Business Day occurring on or after the first anniversary of the Closing Date (each such date, a "**Class A Optional Redemption Date**"), all or a portion of the Outstanding Principal Balance of the Class A Notes (such redemption, a "**Class A Optional Redemption**"), for a Redemption Price equal to the sum of (i) the amount of the Outstanding Principal Balance of the Class A Notes being redeemed on such Class A Optional Redemption Date, plus (ii) accrued and unpaid interest (including Additional Interest, if any) thereon to the Class A Optional Redemption Date, plus (iii) if occurring prior to the October 2028 Payment Date, a redemption premium (the "**Class A Redemption Premium**") calculated as follows:

The Class A Redemption Premium will be an amount equal to the product of (x) a fraction (expressed as a percentage), the numerator of which is the amount of the Outstanding Principal Balance of the Class A Notes being redeemed and the denominator of which is the Outstanding Principal Balance of all Class A Notes immediately prior to such redemption and (y) the excess, if any, of (i) the sum of the present values of all the scheduled payments of principal and interest based upon Scheduled Principal Payment Amounts of the Class A Notes from the Class A Optional Redemption Date to and including the October 2028 Payment Date (assuming full prepayment on such date) discounted monthly to the Class A Optional Redemption Date at a rate equal to the Treasury Rate plus three-quarters of one percent (0.75%), based on a 360-day year of twelve 30-day months, over (ii) the Outstanding Principal Balance of the Class A Notes, plus any accrued but unpaid interest thereon.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;No Class B Optional Redemption may occur prior to the first anniversary of the Closing Date (provided, however, redemptions made in connection with any Involuntary Dispositions, Scrap Value Dispositions, Purchase Option Dispositions or Permitted Discretionary Sales in accordance with the terms of the Indenture will be permitted) or while any Class A Notes are Outstanding unless the same are concurrently redeemed in full (or, if no Early Amortization Event has occurred and is continuing, a partial Optional Redemption of the Class B Notes may be effected if the Issuer concurrently effects an Optional Redemption in part of the Class A Notes within such Series in the same proportion as the Optional Redemption in part of the Class B Notes). Subject to the restrictions in Sections 3.12 and 3.13 of the Master Indenture, the Issuer will have the option to prepay, in an Optional Redemption on any on any Business Day occurring on or after the first anniversary of the Closing Date (each such date, a "**Class B Optional Redemption Date**"), all or a portion of the Outstanding Principal Balance of the Class B Notes (any such redemption, a "**Class B Optional Redemption**"), for a Redemption Price

equal to the sum of (i) the amount of the Outstanding Principal Balance of the Class B Notes being redeemed on such Class B Optional Redemption Date, plus (ii) accrued and unpaid interest (including Additional Interest, if any) thereon to the Class B Optional Redemption Date, plus (iii) if occurring prior to the October 2028 Payment Date, a redemption premium (the "**Class B Redemption Premium**") calculated as follows:

The Class B Redemption Premium will be an amount equal to the product of (x) a fraction (expressed as a percentage), the numerator of which is the amount of the Outstanding Principal Balance of the Class B Notes being redeemed and the denominator of which is the Outstanding Principal Balance of all Class B Notes immediately prior to such redemption and (y) the excess, if any, of (i) the sum of the present values of all the scheduled payments of principal and interest based upon Scheduled Principal Payment Amounts of the Class B Notes from the Class B Optional Redemption Date to and including the October 2028 Payment Date (assuming full prepayment on such date), discounted monthly to the Class B Optional Redemption Date at a rate equal to the Treasury Rate plus three-quarters of one percent (0.75%), based on a 360-day year of twelve 30-day months; over (ii) the aggregate Outstanding Principal Balance of the Class B Notes plus any accrued but unpaid interest thereon.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c)&nbsp;&nbsp;&nbsp;&nbsp;For purposes of calculating the applicable Redemption Premium, the term "**Treasury Rate**" means, with respect to each applicable Series 2026-1 Note, a per annum rate (expressed as a monthly equivalent and as a decimal and, in the case of United States Treasury bills, converted to a bond equivalent yield), determined to be the per annum rate equal to the monthly yield to maturity for United States Treasury securities maturing on the Average Life Date of such applicable Series 2026-1 Note as determined by interpolation between the most recent weekly average yields to maturity for two series of United States Treasury securities, (i) one maturing as close as possible to, but earlier than, the Average Life Date of such Series 2026-1 Note and (ii) the other maturing as close as possible to, but later than, the Average Life Date of such Series 2026-1 Note, in each case, as published in the most recent H.15(519) (or, if a weekly average yield to maturity of United States Treasury securities maturing on the Average Life Date of such Series 2026-1 Note is reported in the most recent H.15(519), as published in H.15(519)). "**H.15(519)**" means "Statistical Release H.15(519), Selected Interest Rates," or any successor publication published by the Board of Governors of the Federal Reserve System. The most recent H.15(519) means the latest H.15(519) which is published prior to the close of business on the third (3rd) Business Day preceding the scheduled prepayment date.

The term "**Average Life Date**" of each applicable Series 2026-1 Note means the date which follows the prepayment date by a period equal to the Remaining Weighted Average Life of such Series 2026-1 Note. The "**Remaining Weighted Average Life**" of a Series 2026-1 Note at the prepayment or determination date of such Series 2026-1 Note shall be the number of days equal to the quotient obtained by dividing (a) the sum of the products obtained by multiplying (i) the Scheduled Principal Payment Amount for each remaining Payment Date (from the applicable Optional Redemption Date to the October 2028 Payment Date, in the case of the Class A Notes and the Class B Notes, in each case, assuming full prepayment on such Payment Date, as applicable) by (ii) the number of days from and including the prepayment or

determination date to but excluding the scheduled payment date of such principal payment, by (b) the Outstanding Principal Balance of the applicable Series 2026-1 Notes on such date of prepayment or determination. The Issuer will calculate (or cause to be calculated) the applicable Redemption Price and Redemption Premium (if any) and deliver such information in writing to the Indenture Trustee at the time that it gives notice of an Optional Redemption pursuant to Sections 3.12 and 3.13 of the Master Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp;Subject to the restrictions in Sections 3.12 and 3.13 of the Master Indenture, the Issuer will have the option to prepay, in an Optional Redemption on any Business Day occurring on or after the October 2028 Payment Date (each such Payment Date, a "**Series 2026-1 Optional Redemption Date**"), all of the Outstanding Principal Balance of the Series 2026-1 Notes, for the Redemption Price equal to the Outstanding Principal Balance of the Series 2026-1 Notes, plus accrued and unpaid interest thereon (including Additional Interest, if any) to the Series 2026-1 Optional Redemption Date; provided, however, that such Redemption Price shall not include any Redemption Premium.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;&nbsp;Any Optional Redemption may be funded with funds in the Collections Account, with the proceeds of Additional Notes or cash Capital Contributions or with any other funds of the Issuer.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)&nbsp;&nbsp;&nbsp;&nbsp;Notwithstanding anything herein to the contrary, no Redemption Premium will be due as a result of (i) any Permitted Discretionary Sales which, in the aggregate, (a) if occurring prior to the first anniversary of the Closing Date, are less than 25% of the sum of (x) the Adjusted Value of the Portfolio Railcars owned by the Issuer on the Closing Date calculated as of the Closing Date and (y) the Adjusted Value of the Portfolio Railcars acquired by the Issuer after the Closing Date (if any) calculated as of the relevant Delivery Date and (b) if occurring on or after the first anniversary of the Closing Date, which in the aggregate are less than 30% of the sum of (x) the Adjusted Value of the Railcars owned by the Issuer on the Closing Date calculated as of the Closing Date and (y) the Adjusted Value of the Railcars contributed on any Delivery Date after the Closing Date calculated as of such Delivery Date, (ii) any Involuntary Railcar Dispositions, Purchase Option Dispositions or Scrap Value Disposition, (iii) in respect of, or during, an Early Amortization Event or if an Event of Default shall have occurred and is continuing, or (iv) a redemption of the Series 2026-1 Notes occurring on or after the October 2028 Payment Date.

**Section 2.07.** <u>Manner of Payment</u>. Except as otherwise provided in Section 2.05 of the Master Indenture, all payments on the Series 2026-1 Notes payable on each Payment Date shall be paid to the Series 2026-1 Noteholders reflected in the Register as of the related Record Date by wire transfer of immediately available funds for receipt prior to 2:00 p.m. (New York time) on such Payment Date.
