Note 1 — Background and Basis of Presentation

NextDecade Corporation, a Delaware corporation, is a Houston-based energy company primarily engaged in construction and development activities related to the liquefaction of natural gas and sale of LNG. We are constructing and developing a natural gas liquefaction and export facility located in the Rio Grande Valley near Brownsville, Texas (the “Rio Grande LNG Facility”). Construction of Trains 1–3 (“Phase 1”) by Phase 1 LLC, Train 4 by Train 4 LLC, and Train 5 by Train 5 LLC commenced in July 2023, September 2025, and October 2025, respectively. We are also developing and advancing the permitting process for expansion Trains 6 through 8 at the Rio Grande LNG Facility.

Basis of Presentation

The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information and with Rule 10-01 of Regulation S-X. Accordingly, they do not include all the information and disclosures required by GAAP for complete financial statements and should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2025. In our opinion, all adjustments which are necessary to a fair presentation of the unaudited consolidated financial statements have been included, and all such adjustments are of a normal recurring nature. The results of operations for the three and six months ended June 30, 2026 are not necessarily indicative of the operating results for the full year.

Certain reclassifications have been made to prior period amounts to conform to the current presentation. The Company began presenting operating and maintenance expense, which primarily consists of costs associated with the Rio Grande LNG Facility and pre-operational readiness activities, as a separate line item on its Consolidated Statements of Operations. These reclassifications did not have a material effect on the Company’s financial position, results of operations, or cash flows.

Phase 1 LLC’s Credit Agreements

The total commitments under the CD Credit Agreement and TCF Credit Agreement (together, the “Phase 1 LLC Committed Credit Facilities”) are $7.5 billion and $0.7 billion, respectively.

The CD Credit Agreement includes an additional $250.0 million commitment (the “CD Senior Working Capital Facility”) that can be used to draw revolving loans or issue letters of credit.

The Phase 1 LLC Committed Credit Facilities are senior secured facilities that amortize quarterly beginning on or after 90 days following the completion of certain conditions including commencement of our long-term LNG Sale and Purchase Agreements (“SPAs”) for Train 3. The facilities have a final maturity in July 2030, bear interest at SOFR plus 2.25%, and accrue commitment fees of 0.68% on undrawn amounts.

Phase 1 LLC’s obligations under the Phase 1 LLC committed facilities rank pari passu with each of the Phase 1 LLC committed credit facilities, the Phase 1 Senior Secured Notes, and the Phase 1 Senior Secured Loans, and are secured by the same collateral package as the Phase 1 Senior Secured Notes and Phase 1 Senior Secured Loans.

In June 2026, Phase 1 LLC repaid approximately $904.0 million and $86.0 million of the amounts outstanding under the CD Credit Agreement and TCF Credit Agreement, respectively, resulting in a loss on debt extinguishment of approximately $32.5 million recorded during the three and six months ended June 30, 2026.

In June 2026, Phase 1 HoldCo Borrower entered into a credit agreement (the “Phase 1 HoldCo Borrower Term Loan”) providing for a term loan in an amount of $1.0 billion to (i) make an equity contribution to Phase 1 LLC, which Phase 1 LLC used to reduce outstanding borrowings under its credit facilities, (ii) pay certain fees and expenses associated with the Phase 1 HoldCo Borrower Term Loan and (iii) pay general and administrative expenses of Phase 1 HoldCo Borrower.

The Phase 1 HoldCo Borrower Term Loan matures on June 17, 2033. Interest is payable semi-annually in cash or paid-in-kind (“PIK”) at Phase 1 HoldCo Borrower’s election until the first interest payment date after June 2029 and in cash thereafter. The Phase 1 HoldCo Borrower Term Loan is secured by pledges of the equity interests in the Phase 1 HoldCo Borrower by its holding company and by a first-priority security interest in substantially all personal property of Phase 1 HoldCo Borrower, including its membership interests in Phase 1 LLC.

Train 4 LLC and Train 5 LLC Credit Agreements

In September 2025 and October 2025, Train 4 LLC and Train 5 LLC, respectively, entered into separate credit facilities of up to approximately $3.8 billion and $3.6 billion, respectively, to fund a portion of their respective project costs, related fees and expenses. Obligations under the credit agreements are secured on a first-priority basis by substantially all of the assets of Train 4 LLC and Train 5 LLC, respectively, as well as a pledge of the membership interest in the respective entities.

Borrowings on both credit facilities bear interest at SOFR plus 2.00% (or base rate plus 1.00%), with rating-based step-downs to SOFR +1.875% / base +0.875% upon “Baa2/BBB” and to SOFR +1.75% / base +0.75% upon “Baa1/BBB+.” Undrawn amounts accrue commitment fees at 30% of the applicable margin for SOFR loans. The Train 4 LLC and Train 5 LLC facilities amortize quarterly beginning on or after 90 days following the completion of certain conditions, including commencement of the SPAs for the respective trains, and mature in September 2032 and October 2032, respectively.

The remaining Train 5 Senior Secured Notes will be issued at par in installments through October 2026. Principal amortizes beginning in September 2031 with a final maturity in September 2050.

The Train 5 Senior Secured Notes are senior secured obligations of Train 5 LLC, ranking senior in right of payment to any and all of Train 5 LLC’s future indebtedness that is subordinated to the Train 5 Senior Secured Notes, and equal in right of payment with Train 5 LLC’s other existing and future indebtedness that is senior and secured by the same collateral securing the Train 5 Senior Secured Notes. The Train 5 Senior Secured Notes rank pari passu with the Train 5 LLC Credit Agreement and are secured on a first-priority basis by a security interest in the same collateral package.

Corporate Credit Agreement

In November 2025, Super Holdings, a wholly owned subsidiary of the Company, amended its Corporate Credit Agreement (the “A&R Corporate Credit Agreement”). The A&R Corporate Credit Agreement definestwo distinct tranches of indebtedness:

•Series A Loans: Consists of $100.0 million in aggregate principal that matures on November 17, 2030 and bears interest at 8.0% per annum that is payable quarterly, in cash or PIK, at Super Holding’s election. These loans include a make-whole premium if prepaid prior to November 17, 2028.

◦Exchange Option: The Series A Loans, including any PIK interest, are exchangeable into shares of common stock of the Company at the election of the lenders at an exchange price of $9.50 per share (the “Series A Exchange Option”). This option is available from the 180th day after November 17, 2025 through maturity. The Series A Exchange Option is accounted for as a derivative liability (see Note 6 — Derivatives).

•Series B Loans: Consists of the remaining principal that matures on October 16, 2030 and bears interest at 13.5% per annum. Prior to March 31, 2027, Super Holdings may elect to pay up to 100% of interest in cash or in kind and is required to pay 50% of interest in kind and 50% of interest in cash thereafter. These loans include a make-whole premium if prepaid prior to June 30, 2028, and a declining prepayment penalty structure thereafter.

Obligations under the A&R Corporate Credit Agreement are secured on a first-priority basis by all of the equity interest in Super Holdings and its direct subsidiaries.

Debt Covenants and Compliance

Each of the Company’s debt instruments contain customary negative covenants that, among other things, limit the ability of the borrower and its subsidiaries to incur additional indebtedness, create liens, make restricted payments (including dividends), make certain investments, and sell all or substantially all assets.

Certain of the Company’s credit agreements also include covenants that, among other things, require the borrower and its subsidiaries to maintain a specified minimum historical debt service coverage ratio as of a specified date in the respective agreement, and covenants that restrict the net assets of the respective subsidiaries from being distributed to NextDecade, unless certain conditions are met.

Fair Value Disclosures

The following table shows the carrying amount and estimated fair value of our debt (in thousands):

The fair value of the debt included in the table above was calculated using a lattice model and is classified as Level 2 in the fair value hierarchy.

The fair values of the CD Credit Agreement, TCF Credit Agreement, and Train 4 LLC Credit Agreement approximate their respective carrying amounts because their variable interest rates align to market interest rates. The fair value of the Phase 1 HoldCo Borrower Term Loan approximates its carrying amount because of the close proximity of the issuance of the debt to June 30, 2026.

Note 6 — Derivatives

To manage interest rate volatility, the Company has entered into interest rate swap agreements (the “Swaps”) to hedge a portion of the floating-rate interest payments associated with the credit agreements described in Note 5 — Debt. These include Swaps entered into by Phase 1 LLC in July 2023 and by Train 4 LLC, Train 5 LLC, and FinCo in the second half of 2025 for their respective debt obligations.

In June 2026, the Company reduced the notional amount of certain of the Phase 1 Swaps, resulting in an approximate $109.2 million receivable due to us based on the fair value of the notional reduction as of the transaction date less transaction costs of approximately $2.6 million. This receivable is classified within Prepaid expenses and other current assets within our Consolidated Balance Sheet. See Note 11 — Subsequent Events for additional information about the receivable.

As of June 30, 2026, the Company had the following Swaps outstanding (in thousands):

(1) Phase 1, Train 4, Train 5, and FinCo Swaps, have early mandatory termination dates in July 2030, September 2032, October 2032, and October 2031, respectively.

The Swaps are measured at fair value each reporting period using an income approach (Level 2) based on observable market inputs, including SOFR forward curves. Changes in fair value are recorded within our Consolidated Statement of Operations.

Series A Exchange Option

The Series A Exchange Option (see Note 5 — Debt) is measured at fair value each reporting period using a lattice model (Level 2), and changes in fair value are recorded within our Consolidated Statement of Operations.

Warrants

The Company issued approximately 9.2 million warrants (the “Warrants”) in connection with the A&R Corporate Credit Agreement that consist of approximately 3.6 million warrants with an exercise price of $7.15 per share and approximately 5.6 million warrants with an exercise price of $9.30 per share. Approximately 7.2 million of the Warrants mature in 2031 and the approximately 2.0 million remaining warrants mature in 2032. The Warrants may be exercised by the holder solely on a cashless exercise basis at any time prior to their expiration.

Subject to certain liquidity conditions, the Company may cause the cash exercise of approximately 3.6 million of these warrants if the 30-day volume weighted average price of the Company’s common stock and the closing price of the Company’s common stock immediately prior to the date of exercise equals or exceeds $13.50 per share or $15.00 per share during specified periods in 2026 and 2027, respectively.

The Warrants are accounted for as derivative liabilities and are remeasured each period using either a Black-Scholes model or Monte Carlo, depending on the terms of the instrument (Level 2). Changes in fair value are recorded within our Consolidated Statement of Operations.

Note 7 — Variable Interest Entities

Phase 1 Holdings, Train 4 Holdings, Train 5 Holdings, and their wholly owned subsidiaries were established to construct and operate Phase 1, Train 4, and Train 5 of the Rio Grande LNG Facility, respectively. The Company is not obligated to fund their losses.

The equity investors at risk, as a group, lack the characteristics of a controlling financial interest. Additionally, through agreements with NextDecade LLC, the Company holds decision-making rights over construction and key operational aspects of Phase 1 LLC, Train 4 LLC, and Train 5 LLC, which agreements can only be terminated by equity holders for cause. Based on these factors, the

Company holds a variable interest in Phase 1 Holdings, Train 4 Holdings, and Train 5 Holdings, and is their primary beneficiary, resulting in the consolidation of these entities in these Consolidated Financial Statements.

The following table presents the summarized combined assets and liabilities (in thousands) of Phase 1 Holdings, Train 4 Holdings, and Train 5 Holdings, which are included in the Company’s Consolidated Balance Sheets. The assets in the table below may only be used to settle the obligations of Phase 1 Holdings, Train 4 Holdings, and Train 5 Holdings, respectively. In addition, there is no recourse to NextDecade for the consolidated VIE’s liabilities. The assets and liabilities in the table below include only the assets and liabilities of Phase 1 Holdings, Train 4 Holdings, Train 5 Holdings, and their respective subsidiaries and exclude intercompany balances between Phase 1 Holdings, Train 4 Holdings, and Train 5 Holdings and NextDecade, which are eliminated in the Consolidated Financial Statements of NextDecade.

Related Party Transactions

TotalEnergies SE and its subsidiaries (together, “TotalEnergies”) are related parties under Accounting Standards Codification 850, Related Party Disclosures, due to TotalEnergies’s ownership of more than 10% of the Company’s common stock. The Company entered into commercial and financing arrangements with TotalEnergies as part of the final investment decisions for Phase 1 and Train 4, including long-term LNG sale and purchase agreements for Phase 1 and Train 4 and equity commitments to Phase 1 Holdings and Train 4 Holdings. TotalEnergies also provides contingent credit support for the TCF Credit Agreement.

For the three and six months ended June 30, 2026, TotalEnergies contributed approximately $329.1 million and $377.5 million under its equity commitments to Phase 1 Holdings, respectively.

Note 8 — Loss Per Share

The computation of basic and diluted loss per share is as follows (in thousands, except per share amounts):

Potentially dilutive shares related to unvested restricted stock and restricted stock units, outstanding stock options, and the Series A Exchange Option were excluded from the calculation of diluted loss per share for all periods presented because their effect would have been antidilutive. Potentially dilutive shares related to the Warrants were included from the calculation of diluted loss per share for the three months ended June 30, 2026, and excluded from the remaining periods presented because their effect would have been antidilutive. See Note 5 — Debt and Note 6 — Derivatives for additional information about the Series A Exchange Option and the Warrants, respectively.

Note 9 — Commitments and Contingencies

Legal Proceedings

From time to time the Company may be subject to various claims and legal actions that arise in the ordinary course of business. As of June 30, 2026, management is not aware of any claims or legal actions against the Company that, separately or in the aggregate, are likely to have a material adverse effect on the Company’s financial position, results of operations, or cash flows, although the Company cannot guarantee that a material adverse effect will not occur.
