***RG5 Financing Documents***

On October 16, 2025 (the "FID Date"), Rio Grande LNG Train 5, LLC, a Delaware limited liability company ("RG5") and an indirect subsidiary of NextDecade Corporation ("NextDecade" or the "Company"), entered into the T5 Common Terms Agreement, the T5 Equity Contribution Agreement, the T5 Collateral and Intercreditor Agreement, the T5 Credit Agreement, the Indenture and the Note Purchase Agreement, each as further described below (each, as defined below, and collectively, together with each agreement governing future Train 5 Senior Secured Debt, the "T5 Senior Secured Debt Instruments"). RG5 also entered into other related security documents described below. The Train 5 Senior Secured Debt Instruments and certain secured hedge agreements rank pari passu in respect of the collateral and in right of payments, as further described below. "T5 Senior Secured Debt" as used herein shall mean all: (a) senior loans and indebtedness incurred under the T5 Credit Agreement and the Notes issued pursuant to the Indenture and the Note Purchase Agreement; (b) Working Capital Debt; (c) Replacement Debt; (d) Relevering Debt; and (e) Supplemental Debt, each as defined and further described below. The "T5 Senior Secured Debt Holder Representatives" shall mean (and will include) the T5 Administrative Agent under the T5 Credit Agreement, the Trustee under the Indenture and any relevant representative of the holders of such T5 Senior Secured Debt under any future Senior Secured Debt Instrument.

*T5 Common Terms Agreement*

On the FID Date, RG5 entered into a Common Terms Agreement (the "T5 Common Terms Agreement") with MUFG Bank, Ltd., as the T5 intercreditor agent (in such capacity, the "T5 Intercreditor Agent"). The T5 Common Terms Agreement sets out certain provisions regarding, among other things: (a) common representations and warranties of RG5; (b) common covenants of RG5; and (c) common events of default under the T5 Senior Secured Debt Instruments. Any T5 Senior Secured Debt Holder Representative will be required to accede to the T5 Common Terms Agreement.

The T5 Common Terms Agreement also provides restrictions and requirements for RG5's incurrence of additional Train 5 Senior Secured Debt, and allows for (subject to any additional requirements under other T5 Senior Secured Debt Instruments) the incurrence of (a) working capital debt, the proceeds of which shall be permitted to be used solely for working capital purposes related to the Train 5 Project (as defined below) (the "Working Capital Debt"), (b) replacement debt, the proceeds of which, among other things, may be used to refinance the funded or unfunded commitments of existing T5 Senior Secured Debt (other than Working Capital Debt) (the "Replacement Debt"), (c) relevering debt, the proceeds of which, among other things, may be used to fund project costs, fund any reserves and to the extent outstanding, fund distributions to the T5 Pledgor (as defined below) (the "Relevering Debt"), and (d) supplemental debt, the proceeds of which, among other things, may be used to finance project costs and permitted capital improvements and for other purposes further specified in the T5 Common Terms Agreement (the "Supplemental Debt").

*T5 Collateral and Intercreditor Agreement*

On the FID Date, RG5 entered into a Collateral and Intercreditor Agreement (the "T5 Collateral and Intercreditor Agreement") with the T5 Intercreditor Agent and Mizuho Bank (USA), as the T5 collateral agent (the "T5 Collateral Agent"). The T5 Collateral and Intercreditor Agreement sets forth the intercreditor arrangements that govern the relationships among the holders of the various classes of T5 Senior Secured Debt. In addition, each class of T5 Senior Secured Debt Holders generally is subject to voting arrangements with respect to amendments, supplements, and waivers by such class. The T5 Collateral and Intercreditor Agreement also includes various provisions regarding the collateral granted to all holders of T5 Senior Secured Debt and the application of proceeds thereof prior to and upon the exercise of remedies by the holders of Senior Secured Debt. Any future Senior Secured Debt Holder Representative will be required to accede to the T5 Collateral and Intercreditor Agreement.

*T5 Security Documents*

Under the T5 Pledge Agreement dated as of the FID Date, between Rio Grande LNG Train 5 Holdings, LLC, a Delaware limited liability company (the "T5 Pledgor"), and the T5 Collateral Agent, the T5 Pledgor has granted a security interest in favor of the T5 Collateral Agent for the benefit of the holders of the T5 Senior Secured Debt in the limited liability company interest in RG5 held by the T5 Pledgor.

On the FID Date, RG5 also granted a security interest in favor of the T5 Collateral Agent for the benefit of the holders of the T5 Senior Secured Debt, in substantially all of RG5's real and personal property, including RG5's proportionate equity interests in the subsidiaries of Rio Grande LNG, LLC ("RGLNG") that RG5 will acquire at the project completion date of the Train 5 Project, pursuant to a security agreement and a deed of trust.

------

*T5 Accounts Agreement*

On the FID Date, RG5 entered into an Accounts Agreement (the "T5 Accounts Agreement") with the T5 Collateral Agent, and JPMorgan Chase Bank, N.A., as the T5 accounts bank. Prior to the project completion date, the T5 Accounts Agreement provides for the funding of engineering, procurement and construction ("EPC") and other costs in respect of the fifth liquefaction train and related common facilities (the "Train 5 Project") of the multi-plant integrated natural gas and liquefaction and liquefied natural gas ("LNG") export terminal facility located at the Port of Brownsville in southern Texas (the "Rio Grande Facility") through a customary construction account. Following the project completion date, RG5's revenues will be applied according to a customary waterfall under the T5 Accounts Agreement.

*T5 Credit Agreement*

On the FID Date, RG5 entered into a Credit Agreement (the "T5 Credit Agreement") by and among RG5, as borrower, MUFG Bank, Ltd., as the administrative agent (in such capacity, the "T5 Administrative Agent"), the T5 Collateral Agent, in its capacity as the collateral agent, and the senior lenders party thereto. The T5 Credit Agreement provides for a construction/term loan facility (the "T5 Construction/Term Loans") in an amount up to $3.589 billion available to RG5 solely to partially finance the design, engineering, development, procurement, construction, installation, testing, completion, ownership, operation and maintenance of the Train 5 Project and to pay certain fees and expenses associated with the T5 Credit Agreement and the loans made thereunder.

The principal of the T5 Construction/Term Loans is repayable in quarterly installments payable each March 31, June 30, September 30, and December 31, beginning on the first such quarterly payment date to occur on or after the date that is ninety days following the project completion date (the "Initial Principal Payment Date"). RG5 may make borrowings based on SOFR plus the applicable margin (2.00%) or the base rate plus the applicable margin (1.00%); provided, that, such applicable margin will be decreased to (a) 1.875% for SOFR and 0.875% for base rate during any period when the T5 Construction/Term Loan is rated "Baa2" by Moody's or "BBB" by S&P or Fitch, and (b) 1.75% for SOFR and 0.75% for base rate during any period when the T5 Construction/Term Loan is rated "Baa1" by Moody's or "BBB+" by S&P or Fitch. RG5 is also required to pay commitment fees on the undrawn amounts of the T5 Construction/Term Loans.

The T5 Credit Agreement includes certain covenants and events of default that are supplemental to the covenants and events of default set forth in the T5 Common Terms Agreement and that are customary for project financing facilities of this type. The T5 Credit Agreement includes a requirement that interest rates for a minimum of 75% of the projected principal amount of T5 Senior Secured Debt outstanding and a maximum of 110% of the projected principal amount of T5 Senior Secured Debt be hedged or have fixed interest rates. In addition, certain covenants and events of default in the T5 Credit Agreement are more restrictive than the corresponding covenants and events of default in the T5 Common Terms Agreement, including covenants limiting RG5's ability to incur additional indebtedness, make certain investments or pay dividends (which are subject to customary conditions set out in the T5 Credit Agreement and certain related financing documents) or distributions on equity interests or subordinated indebtedness or purchase, redeem, or retire equity interests, sell or transfer assets, incur liens, dissolve, liquidate, consolidate, merge, sell, or lease all or substantially all of RG5's assets or enter into certain LNG sales contracts. The T5 Credit Agreement includes a requirement for RG5 to maintain a historical debt service coverage ratio of at least 1.10:1.00 at the end of each fiscal quarter starting from the Initial Principal Payment Date, a default of which may, in certain circumstances, be cured with equity contributions.

The T5 Credit Agreement provides for mandatory prepayments under customary circumstances, including mandatory prepayments with the proceeds of certain insurance payments and condemnation awards, upon receipt of certain proceeds from asset sales, upon receipt of performance liquidated damages under certain construction contracts, or upon termination of certain LNG sale and purchase agreements.

Upon an event of default under the T5 Credit Agreement (and after all applicable cure periods have elapsed), the T5 Administrative Agent may, or upon the direction of the required lenders will, accelerate all or any portion of the senior loans and other obligations due and payable under the T5 Credit Agreement or terminate all outstanding loan commitments under the T5 Credit Agreement, and, with respect to letters of credit outstanding at the time of such event of default, require RG5 to cash collateralize such letters of credit. Such acceleration or termination is automatic following an event of default under the T5 Credit Agreement relating to bankruptcy or insolvency.

*T5 Indenture*

On the FID Date, RG5 entered into a Note Purchase Agreement (the "Note Purchase Agreement") with the purchasers named therein (the "Purchasers"), to issue and sell to the Purchasers $500 million aggregate principal amount of its 6.56% Senior Secured Notes due 2050 (the "Notes"). The Notes will be issued at par and will be issued on an installment basis on each of December 28, 2025, April 1, 2026, July 1, 2026 and October 1, 2026 (each, an "Issuance

------

Date"). The Notes will be issued pursuant to the indenture, dated as of the FID Date (the "Indenture"), between RG5 and Wilmington Trust, National Association, as Trustee under the Indenture (the "Trustee").

The sale of the Notes was not registered under the Securities Act of 1933 (the "Securities Act"), and the Notes were sold in a private placement in reliance on Section 4(a)(2) of the Securities Act. The Notes have not been and will not be registered under the Securities Act or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the Securities Act and applicable state laws.

Under the terms of the Indenture, the Notes will be amortized over a period of 20 years beginning September 30, 3031, with a final maturity on September 30, 2050. The Notes will accrue interest from their respective Issuance Date at a rate equal to 6.56% per annum on the outstanding principal amount, with such interest payable semi-annually, in cash in arrears, on March 30 and September 30 of each year, beginning on March 30, 2026 (or the next succeeding business day) with respect to the first tranche of Notes.

The Notes are senior secured obligations of RG5 and rank senior in right of payment to any and all of RG5's future indebtedness that is subordinated in right of payment to the Notes and pari passu with all of RG5's existing and future indebtedness (including all obligations under the other T5 Senior Secured Debt Instruments) that is senior and secured by the same collateral securing the Notes. The Notes are effectively senior to all of RG5's senior indebtedness that is unsecured to the extent of the value of the assets constituting the collateral securing the Notes.

At any time or from time to time prior to June 30, 2050, RG5 may redeem all or a part of the Notes, at a redemption price equal to the "make-whole" price set forth in the Indenture, plus accrued and unpaid interest, if any, to, but excluding, the date of redemption. RG5 also may, at any time on or after June 30, 2050, redeem the Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the date of redemption.

The Indenture also contains customary terms and events of default and certain covenants that, among other things, limit RG5's ability to incur additional indebtedness, make certain investments or pay dividends or distributions on equity interests or subordinated indebtedness or purchase, redeem, or retire equity interests, sell or transfer assets, incur liens, dissolve, liquidate, consolidate, merge, or sell or lease all or substantially all of RG5's assets. The Indenture further requires RG5 to submit certain reports and information to the Trustee and holders of the Notes, maintain certain LNG offtake agreements, and maintain a debt service coverage ratio of at least 1.10:1.00 at the end of each fiscal quarter starting from the Initial Principal Payment Date. With respect to certain events, including a change of control event and receipt of certain proceeds from asset sales, events of loss or liquidated damages, the Indenture requires RG5 to make an offer to repurchase the Notes at 101% (with respect to a change of control event) or par (with respect to each other event), in each case on the terms specified in the Indenture. The Indenture covenants are subject to a number of important limitations and exceptions, including the terms and covenants contained in the T5 Common Terms Agreement.

***FinCo and Super FinCo Facilities***

*FinCo Credit Agreement*

On the FID Date, Rio Grande LNG Phase 1 FinCo, LLC ("Phase 1 FinCo") and Rio Grande LNG Phase 2 FinCo, LLC ("Phase 2 FinCo" and together with Phase 1 FinCo, the "FinCo Borrowers"), each a Delaware limited liability company and an indirect subsidiary of the Company, entered into an Amended and Restated Credit Agreement (the "A&R FinCo Credit Agreement") by and among the FinCo Borrowers, as borrowers, MUFG Bank, Ltd., as the administrative agent (in such capacity, the "FinCo Administrative Agent"), HSBC USA Bank, N.A., as the collateral agent (the "FinCo Collateral Agent"), and the senior lenders party thereto. As amended and restated, the A&R FinCo Credit Agreement provides for a loan and letter of credit facility (the "FinCo Facility") in an amount up to $1.463 billion available to the FinCo Borrowers, with a letter of credit sublimit of approximately $1.192 billion, to be used to fund equity contributions by the ND Member (as defined below) to the T4 JVCo and the T5 JVCo for further contribution to RG4 and RG5, respectively, to finance interest during construction and certain fees and expenses associated with the FinCo Credit Agreement and the loans made and letters of credit issued thereunder, and to fund the debt service reserve account relating thereto, up to an amount equal to six months of scheduled debt service. Letters of credit may be issued under the FinCo Facility for the purpose of supporting ND Member's obligations to make equity contributions to T4 JVCo and T5 JVCo.

Phase 1 FinCo indirectly owns the membership interests in Rio Grande LNG Intermediate Super Holdings, LLC (the "ND Phase 1 Member"), which holds NextDecade's equity interests in the joint venture entity that owns the first three trains of the Rio Grande Facility ("Phase 1 JVCo"). Phase 2 FinCo owns the membership interests in Rio Grande LNG Phase 2 Intermediate Super Holdings, LLC (the "ND Member"), which holds NextDecade's retained equity interests in (i) Rio Grande LNG Train 4 Intermediate Holdings, LLC ("T4 JVCo"), the joint venture entity that indirectly wholly owns RG4, which will own the fourth liquefaction train of the Rio Grande Facility, and (ii) Rio Grande LNG Train 5

------

Intermediate Holdings, LLC ("T5 JVCo"), the joint venture entity that indirectly wholly owns RG5, which will own the fifth liquefaction train of the Rio Grande Facility.

The FinCo Facility will be available to the FinCo Borrowers for loans and letters of credit on and after the date on which the FinCo Borrowers deliver notice to the FinCo Intercreditor Agent confirming the issuance by FERC of a remand order maintaining the Section 3 authorization of the Rio Grande Facility and the earliest to occur of (a) expiration of the 30-day rehearing period with FERC without any requests for rehearing, (b) denial of any rehearing requests by operation of law, which occurs automatically if FERC does not respond to a request for rehearing within 30 days of such request for rehearing, or (c) issuance of an order from FERC denying any rehearing request (such earliest date, the "Remand Satisfaction Date"). The remand order was issued by FERC on August 29, 2025, and thereafter petitioners made a request for rehearing on September 29, 2025. We currently expect the Remand Satisfaction Date to occur, and the FinCo Facility to be initially available to the FinCo Borrowers, on or around October 29, 2025.

The FinCo Facility will mature on the fifth anniversary of the FID Date; provided, that the FinCo Borrowers may elect to extend the maturity date by a year at any time within the 90-day period prior to the fifth anniversary of the FID Date. The FinCo Borrowers may make borrowings based on SOFR plus the applicable margin (3.50%) or the base rate plus the applicable margin (2.50%). The FinCo Borrower are also required to pay commitment fees on the undrawn amounts of the FinCo Facility and letter of credit fees on outstanding, undrawn letters of credit.

The A&R FinCo Credit Agreement includes certain covenants and events of default that are customary for financing facilities of this type, including a requirement that interest rates for a minimum of 90% of the projected principal amount of the FinCo Facility outstanding and a maximum of 100% of the projected principal amount of the FinCo Facility be hedged or have fixed interest rates. In addition, the A&R FinCo Credit Agreement contains covenants limiting the ability of the FinCo Borrowers to incur additional indebtedness, make certain investments or pay dividends (which are subject to customary conditions set out in the A&R FinCo Credit Agreement and certain related financing documents) or distributions on equity interests or subordinated indebtedness or purchase, redeem, or retire equity interests, sell or transfer assets, incur liens, dissolve, liquidate, consolidate, merge, sell, or lease all or substantially all of the assets of the FinCo Borrowers. The A&R FinCo Credit Agreement includes a requirement for the FinCo Borrowers to maintain a stand-alone debt service coverage ratio of at least 1.10:1.00 at the end of each fiscal quarter starting from the first quarterly payment date to occur on or after the date that is ninety days following the Train 5 project completion date, a default of which may, in certain circumstances, be cured with equity contributions.

The A&R FinCo Credit Agreement provides for mandatory prepayments with the proceeds of certain asset sales and sales of membership interests owned by subsidiaries of the FinCo Borrowers in the Phase 1 JVCo, T4 JVCo or T5 JVCo. In addition, the A&R FinCo Credit Agreement contains a quarterly excess cash flow sweep equal to (i) 100% of excess cash flow until prepayments or cancellation of commitments equal 25% of the FinCo Facility principal amount, (ii) 75% of excess cash flow until prepayments or cancellation of commitments equal 50% of the FinCo Facility principal amount, and (iii) 50% of excess cash flow thereafter.

In connection with entering into the A&R FinCo Credit Agreement, under an amended and restated pledge agreement dated as of the FID Date, by and among Rio Grande LNG Phase 1 FinCo Holdings, LLC, a Delaware limited liability company (the "Phase 1 FinCo Pledgor"), Rio Grande LNG Phase 2 FinCo Holdings, LLC, a Delaware limited liability company (the "Phase 2 FinCo Pledgor" and together with the Phase 1 FinCo Pledgor, the "FinCo Pledgors") and the FinCo Collateral Agent, the FinCo Pledgors granted a security interest in favor of the FinCo Collateral Agent for the benefit of the lenders of the FinCo Facility in the limited liability company interests in the FinCo Borrowers held by the respective FinCo Pledgor.

On the FID Date, the FinCo Borrowers also granted a security interest in favor of the FinCo Collateral Agent, for the benefit of the lenders of the FinCo Facility, in substantially all of the FinCo Borrowers' real and personal property, including their respective equity interests in the ND Phase 1 Member and the ND Member, pursuant to an amended and restated security agreement and deed of trust.

*Super FinCo Credit Agreement*

On the FID Date, Rio Grande LNG Phase 1 Super FinCo, LLC ("Phase 1 Super FinCo") and Rio Grande LNG Phase 2 Super FinCo, LLC ("Phase 2 Super FinCo" and together with Phase 1 Super FinCo, the "SF Borrowers"), each a Delaware limited liability company and an indirect subsidiary of the Company, entered into an amendment (the "SF Amendment") to that certain Credit Agreement (such Credit Agreement, as amended, the "SF Credit Agreement"), dated as of September 9, 2025 (the "Train 4 FID Date"), by and among the SF Borrowers, as borrowers, Global Loan Agency Services, as the administrative agent and collateral agent (the "SF Administrative Agent" or "SF Collateral Agent", as applicable) and the financial institutions party thereto, including an affiliate of Global Infrastructure Partners, as lenders (the "SF Lenders"). The SF Borrowers are the respective direct parents of the FinCo Pledgors.

------

The Series B Loan and the original $600 million term loan extended on September 9, 2025 (the "Series A Loan") are pari passu and will be consolidated into a single tranche of loans, with an aggregate original principal amount of $1,200 million, on October 31, 2025 (the "SF Loan").

The SF Loan matures on the earlier of (a) September 9, 2033, which is the eighth anniversary of the Train 4 FID Date and (b) the 85<sup>th</sup> day prior to the maturity date of the FinCo Facility, as extended or refinanced. Interest will accrue on the SF Loan from the FID Date at a fixed rate of 13.0% per annum, and will be paid quarterly on each April 30, July 31, October 31, and January 31. The Super FinCo Borrowers may elect to fully pay interest in kind until the first anniversary of the completion of the fourth liquefaction train and related common facilities (the "Train 4 Project") and thereafter may elect to pay interest in kind with respect to up to 50% of each such interest payment date thereafter.

Prior to the fifth anniversary of the Train 4 FID Date, the Super FinCo Borrowers may prepay the SF Loan at a redemption price equal to 100% of the principal amount plus an applicable make whole premium and accrued and unpaid interest to the prepayment date. On and after the fifth anniversary of the Train 4 FID Date, the Super FinCo Borrowers may prepay the SF Loan at par, plus accrued and unpaid interest to the prepayment date. The SF Credit Agreement provides for mandatory prepayments with the proceeds of certain insurance payments and condemnation awards, asset sales, performance liquidated damages under certain construction contracts, termination of certain LNG sale and purchase agreements and the proceeds of certain distributions received by the SF Borrowers from their subsidiaries.

The SF Credit Agreement includes covenants that, among other things, limit the ability of the Super FinCo Borrowers to incur additional indebtedness, make certain investments or pay dividends or distributions on equity interests or subordinated indebtedness or purchase, redeem, or retire equity interests, sell or transfer assets, incur liens or dissolve, liquidate, consolidate, merge.

*Train 5 fully funded with no material impact to NextDecade common shares outstanding*

HOUSTON--(BUSINESS WIRE)—October 16, 2025--NextDecade Corporation (NextDecade or the Company) (NASDAQ: NEXT) announced today that it has made a positive final investment decision (FID) on Train 5 at Rio Grande LNG, closed financial transactions to fully fund Train 5 and related infrastructure, and issued full notice to proceed to Bechtel Energy Inc. (Bechtel) for Train 5.

"Today, we are excited to announce that we have made a positive FID on Train 5, marking the second FID for NextDecade in just over a month," said Matt Schatzman, NextDecade's Chairman and Chief Executive Officer. "This achievement is the result of tireless effort by our team and our partners, and I would like to thank the entire NextDecade team, our equity partners, our Train 5 LNG customers, Bechtel, our financing partners, and our local stakeholders for helping bring Train 5 FID to fruition."

**Positive FID Achieved on Train 5**

On October 16, 2025, NextDecade made a positive FID and issued full notice to proceed to Bechtel under the Company's lump-sum, turnkey engineering, procurement, and construction (EPC) contract for Train 5 and related infrastructure. Train 5 has expected LNG production capacity of approximately 6 million tonnes per annum (MTPA), bringing the total expected LNG production capacity under construction at Rio Grande LNG to approximately 30 MTPA.

Train 5 is commercially supported by 4.5 MTPA of 20-year LNG Sale and Purchase Agreements (SPAs) with JERA, EQT Corporation, and ConocoPhillips. The guaranteed substantial completion date for Train 5, as well as the date of first commercial delivery (DFCD) under the Train 5 LNG SPAs, is anticipated in the first half of 2031.

Project costs for Train 5 and related infrastructure are expected to total approximately $6.7 billion, including EPC costs, owner's costs, contingencies, financing fees and interest during construction, and other costs<sup>1</sup>.

To fully fund the expected costs for Train 5 and related infrastructure, the Company successfully closed on approximately $6.7 billion in committed financing, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $3.59 billion term loan facility at Rio Grande LNG Train 5, LLC;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $0.50 billion private placement notes at Rio Grande LNG Train 5, LLC;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $1.29 billion in equity commitments from NextDecade; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• $1.29 billion in equity commitments from partners Global Infrastructure Partners, a part of BlackRock (GIP), GIC, Mubadala Investment Company (together, the Financial Investors).

NextDecade received $117 million at financial close from Rio Grande LNG Train 5, LLC for development costs and management services.

------

NextDecade has an initial economic interest of 50% in Train 5, which will increase to 70% after the Financial Investors achieve certain returns on their investments in Train 5.

**NextDecade Train 5 Equity Commitment Financed with No Material Impact to Common Shares Outstanding**

NextDecade used $233 million of cash on hand and entered into a total of $1.33 billion in term loans to finance its portion of Train 5 equity funding commitments without a material impact to NextDecade common shares outstanding.

The FinCo Loan is a $729 million delayed draw bank facility that bears interest at SOFR plus 350 basis points. Commitments under the FinCo Loan are cancellable and can be prepaid without penalty.

The SuperFinCo Loan is a $600 million term loan, with net proceeds disbursed at financial close. The SuperFinCo loan bears interest at 13%, with interest payable in kind until one year after Train 5 completion, and is callable at par beginning in September 2030.

**Investor Presentation and Webcast**

NextDecade will host a conference call and webcast to discuss today's announcements on October 17, 2025, at 10:00am Central Time. The webcast and accompanying presentation may be accessed through the Company's website at https://investors.next-decade.com. A replay will also be available after the webcast concludes.

<sup>1</sup> Each expansion train will be obligated to make a payment, at its applicable start-up date, to the trains in commercial operation at such date for such expansion train's proportionate share of the capital costs of the common facilities that such expansion train will access, net of the capital cost of any common facilities constructed under the EPC agreement for the applicable expansion train project, if any.
