Item 8. Financial Statements and Supplementary Data   Index to Consolidated Financial Statements   NextDecade Corporation and Subsidiaries     Page Report of Independent Registered Public Accounting Firm 29 Consolidated Balance Sheets 31 Consolidated Statements of Operations 32 Consolidated Statements of Stockholders’ Equity, Series A and Series B Convertible Preferred Stock 33 Consolidated Statements of Cash Flows 34 Notes to Consolidated Financial Statements 35 Supplemental Information to Consolidated Financial Statements – Summarized Quarterly Financial Data 47   28 Table of Contents   REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM     Board of Directors and Stockholders NextDecade Corporation   Opinion on the financial statements We have audited the accompanying consolidated balance sheets of NextDecade Corporation (a Delaware corporation) and subsidiaries (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of operations, stockholders’ equity, series A and series B convertible preferred stock, and cash flows for the years then ended, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.   Basis for opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.   We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.   Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.   Critical audit matters The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.   Valuation of common stock warrant liabilities   As described further in Note 10 to the financial statements, the Company had $4.2 million of common stock warrant liabilities as of December 31, 2020. At each balance sheet date, management determines the estimated fair value of common stock warrant liabilities using a Monte Carlo valuation method. The following qualitative information is used by management to determine the fair value measurement of the common stock warrant liabilities: stock price, exercise price, risk-free rate, volatility, and the warrants term in years, among other inputs. We identified the valuation of common stock warrant liabilities as a critical audit matter.   The principal considerations for our determination that the valuation of common stock warrant liabilities is a critical audit matter are that (i) there was significant judgment by management when determining the estimated volatility, risk-free interest rate, and the expected life of the common stock warrants, and (ii) the audit effort involved the use of professionals with specialized skill and knowledge to assist in performing procedures and evaluating the audit evidence obtained from these procedures.   Our audit procedures related to the valuation of common stock warrant liabilities included the following, among others.     ● We tested the design of controls over the valuation of common stock warrant liabilities and gained an understanding of the valuation credentials and industry expertise of the third-party valuation group and valuation methodologies used.     ● We tested the schedule of fully dilutive shares used to value common stock warrants by confirming outstanding common stock with the third-party transfer agent and testing the conversion value of preferred stock and dividend issuances.     ● With the assistance of Grant Thornton internal valuation specialists, we tested management’s and the third-party’s process for determining the fair value of common stock warrants, including evaluating significant assumptions used, testing supporting documents, and assessing reasonableness by comparing to historical trends and industry expectations. Certain key inputs/assumptions tested by us included the following:   o Volatility   o Risk-free interest rate   o Warrant terms   29     Sale of Rio Bravo accounting treatment   As described further in Note 5 to the financial statements, on March 2, 2020, the Company completed the sale of Rio Bravo Pipeline Company, LLC (“Rio Bravo”) to Spectra Energy Transmission II, LLC, a wholly owned subsidiary of Enbridge, Inc ("Enbridge"). In connection with the closing of the sale, the Company entered into a precedent agreement where Rio Bravo agreed to provide the Company with firm natural gas transportation services on the proposed interstate natural gas pipeline in a quantity sufficient to match the full operational capacity of each proposed liquefaction train of the liquefied natural gas terminal. Additionally, if the Company fails to issue a full notice to proceed to the terminal contractor on or prior to December 31, 2023, Enbridge has the right to sell the equity interests back to the Company, and the Company has the right to repurchase the equity interests from Enbridge. Due to the aforementioned terms of the agreement, the proceeds from the sale of the equity interests and additional costs incurred by Enbridge are presented as a non-current liability and the assets of Rio Bravo have not been de-recognized in the consolidated balance sheet at December 31, 2020. We identified the sale of Rio Bravo accounting treatment as a critical audit matter.   The principal considerations for our determination that the sale of Rio Bravo accounting treatment is a critical audit matter are (i) the complexity of the terms of the sale agreement, (ii) the complexity and judgment involved in the determination of the applicable accounting authoritative guidance, and (iii) the audit effort involved the use of professionals with specialized skill and knowledge to assist in performing procedures and evaluating the audit evidence obtained from these procedures.   Our audit procedures related to the sale of Rio Bravo accounting treatment included the following, among others.     ● We read the sale agreement.     ● We tested management’s process for concluding on the accounting treatment of the sale of the equity interest in Rio Bravo, including management’s assumptions used to determine the accounting treatment in accordance with the sale agreement.     ● We used our firm specialist resources to assist in auditing management’s conclusions through an accounting consultation.   /s/ GRANT THORNTON LLP   We have served as the Company’s auditor since 2018.

Consolidated Financial Statements     Note  1  — Background and Basis of Presentation   NextDecade Corporation engages in development activities related to the liquefaction and sale of liquefied natural gas (“LNG”). We have focused and continue to focus our development activities on the Rio Grande LNG terminal facility at the Port of Brownsville in southern Texas (the “Terminal”).    Our Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All intercompany accounts and transactions have been eliminated in consolidation.     Note 2 — Summary of Significant Accounting Policies   Use of Estimates   The preparation of Consolidated Financial Statements in conformity with GAAP requires management to make certain estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and the accompanying notes. Management evaluates its estimates and related assumptions regularly, including those related to the value of property, plant and equipment, income taxes including valuation allowances for net deferred tax assets, share-based compensation and fair value measurements. Changes in facts and circumstances or additional information may result in revised estimates, and actual results may differ from these estimates.   Concentrations of Credit Risk   Financial instruments that potentially subject us to a concentration of credit risk consist principally of cash and cash equivalents. We maintain cash balances with a single financial institution, which may at times be in excess of federally insured levels. We have not incurred losses related to these cash and cash equivalent balances to date.   35 Table of Contents   Cash Equivalents   We consider all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents.     Investment Securities   We define investment securities as investments in marketable securities that can be readily converted to cash. We determine the appropriate classification of investment securities at the time of purchase and reevaluate such classification at each balance sheet date. Investment securities are initially recorded at cost and remeasured to fair value, with changes presented in other income in our Consolidated Statements of Operations.   Property, Plant and Equipment   Generally, we begin to capitalize the costs of our development projects once construction of the individual project is probable. This assessment includes the following criteria:     • funding for design and permitting has been identified and is expected in the near-term;     • key vendors for development activities have been identified, and we expect to engage them at commercially reasonable terms;     • we have committed to commencing development activities;     • regulatory approval is probable;     • construction financing is expected to be available at the time of a final investment decision (“FID”);     • prospective customers have been identified and the FID is probable; and     • receipt of customary local tax incentives, as needed for project viability, is probable.   Prior to meeting the criteria above, costs associated with a project are expensed as incurred. Expenditures for normal repairs and maintenance are expensed as incurred.   When assets are retired or disposed, the cost and accumulated depreciation are eliminated from the accounts and any gain or loss is reflected in our Consolidated Statements of Operations.   Property, plant and equipment is carried at historical cost and depreciated using the straight-line method over their estimated useful lives.   Leasehold improvements are depreciated over the lesser of the economic life of the leasehold improvement or the term of the lease, without regard to extension/renewal rights.   Management tests property, plant and equipment for impairment whenever events or changes in circumstances have indicated that the carrying amount of property, plant and equipment might not be recoverable. Assets are grouped at the lowest level for which there are identifiable cash flows that are largely independent of the cash flows of other groups of assets for purposes of assessing recoverability. Recoverability generally is determined by comparing the carrying value of the asset to the expected undiscounted future cash flows of the asset. If the carrying value of the asset is not recoverable, the amount of impairment loss is measured as the excess, if any, of the carrying value of the asset over its estimated fair value.   Warrants   The Company determines the accounting classification of warrants that are issued, as either liability or equity, by first assessing whether the warrants meet liability classification in accordance with Accounting Standards Codification (“ASC”) 480 Distinguishing Liabilities from Equity (“ASC 480” ), and then in accordance with ASC 815 - 40, Accounting for Derivative Financial Instruments Indexed to, and Potentially Settled in, a Company’s Own Stock (“ASC 815 - 40” ). Under ASC 480, warrants are considered liability classified if the warrants are mandatorily redeemable, obligate the issuer to settle the warrants or the underlying shares by paying cash or other assets, or warrants that must or may require settlement by issuing a variable number of shares.   If warrants do not meet liability classification under ASC 480, the Company assesses the requirements under ASC 815 - 40, which states that contracts that require or may require the issuer to settle the contract for cash or a variable number of shares are liabilities recorded at fair value, irrespective of the likelihood of the transaction occurring that triggers the net cash settlement feature. If the warrants do not require liability classification under ASC 815 - 40, in order to conclude equity classification, the Company assesses whether the warrants are indexed to our common stock and whether the warrants are classified as equity under ASC 815 - 40 or other applicable GAAP. After all relevant assessments are made, the Company concludes whether the warrants are classified as liability or equity. Liability classified warrants are required to be accounted for at fair value both on the date of issuance and on subsequent accounting period ending dates, with all changes in fair value after the issuance date recorded in the statements of operations as a gain or loss. Equity classified warrants are accounted for at fair value on the issuance date with no changes in fair value recognized after the issuance date.   36 Table of Contents   Fair Value of Financial Instruments   Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. Hierarchy Levels 1, 2 and 3 are terms for the priority of inputs to valuation techniques used to measure fair value. Hierarchy Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Hierarchy Level 2 inputs are inputs other than quoted prices included within Level 1 that are directly or indirectly observable for the asset or liability. Hierarchy Level 3 inputs are inputs that are not observable in the market. In determining fair value, we use observable market data when available, or models that incorporate observable market data. In addition to market information, we incorporate transaction-specific details that, in management’s judgment, market participants would take into account in measuring fair value. We maximize the use of observable inputs and minimize our use of unobservable inputs in arriving at fair value estimates. Recurring fair-value measurements are performed for investment securities as disclosed in Note 4 – Investment Securities and for Common Stock Warrant liabilities as disclosed in Note 10   – Preferred Stock and Common Stock Warrants . The carrying amount of cash and cash equivalents and accounts payable reported on the Consolidated Balance Sheets approximates fair value due to their short-term maturities.   Treasury Stock   Treasury stock is recorded at cost. Issuance of treasury stock is accounted for on a weighted average cost basis. Differences between the cost of treasury stock and the re-issuance proceeds are charged to additional paid-in capital.   Net Loss Per Share   Net loss per share (“EPS”) is computed in accordance with GAAP. Basic EPS excludes dilution and is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted EPS reflects potential dilution and is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period increased by the number of additional common shares that would have been outstanding if the potential common shares had been issued and were dilutive. The dilutive effect of unvested stock and warrants is calculated using the treasury-stock method and the dilutive effect of convertible securities is calculated using the if-converted method. Basic and diluted EPS for all periods presented are the same since the effect of our potentially dilutive securities are anti-dilutive to our net loss per share, as disclosed in Note 11  – Net Loss Per Share Attributable to Common Stockholders .   Share-based Compensation   We recognize share-based compensation at fair value on the date of grant. The fair value is recognized as expense (net of any capitalization) over the requisite service period. For equity-classified share-based compensation awards, compensation cost is recognized based on the grant-date fair value using the quoted market price of our common stock and not subsequently remeasured. The fair value is recognized as expense, net of any capitalization, using the straight-line basis for awards that vest based on service conditions and using the graded-vesting attribution method for awards that vest based on performance conditions. We estimate the service periods for performance awards utilizing a probability assessment based on when we expect to achieve the performance conditions. For liability classified share-based compensation awards, compensation cost is initially recognized on the grant date using estimated payout levels. Compensation cost is subsequently adjusted quarterly to reflect the updated estimated payout levels based on the changes in our stock price. We account for forfeitures as they occur.   Income Taxes   Provisions for income taxes are based on taxes payable or refundable for the current year and deferred taxes on temporary differences between the tax basis of assets and liabilities and their reported amounts in the Consolidated Financial Statements. Deferred tax assets and liabilities are included in the Consolidated Financial Statements at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized or settled. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the current period’s provision for income taxes. A valuation allowance is recorded to reduce the carrying value of our net deferred tax assets when it is more likely than not that a portion or all of the deferred tax assets will expire before realization of the benefit or future deductibility is not probable. We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the tax position.   Smaller Reporting Company   Under Rule 12b - 2 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Company qualifies as a “smaller reporting company” because the value of its common stock held by non-affiliates as of the end of its most recently completed second fiscal quarter was less than $250 million. For as long as the Company remains a smaller reporting company, it may take advantage of certain exemptions from the SEC’s reporting requirements that are otherwise applicable to public companies that are not smaller reporting companies.   37 Table of Contents     Note 3 — Prepaid Expenses and Other Current Assets   Prepaid expenses and other current assets consisted of the following (in thousands):       December 31,     December 31,       2020     2019   Prepaid subscriptions   $ 29     $ 161   Prepaid insurance     314       292   Prepaid marketing and sponsorships     60       25   Other     267       381   Total prepaid expenses and other current assets   $ 670     $ 859         Note 4 — Investment Securities   We previously invested in Class L shares of the JPMorgan Managed Income Fund.

(“Buyer”), pursuant to which NextDecade LLC sold one hundred percent of the equity interests (the “Equity Interests”) in Rio Bravo Pipeline Company, LLC (“Rio Bravo”) to Buyer for consideration of approximately $ 19.4 million. Buyer paid $ 15.0 million of the purchase price to NextDecade LLC at the Closing and the remainder will be paid within five business days after the date that Rio Grande has received, after a final positive investment decision, the initial funding of financing for the development, construction and operation of the Terminal. In connection with the Closing, Rio Grande LNG Gas Supply LLC, an indirect wholly-owned subsidiary of the Company (“Rio Grande Gas Supply”), entered into (i) a Precedent Agreement for Firm Natural Gas Transportation Service for the Rio Bravo Pipeline (the “RBPL Precedent Agreement”) with Rio Bravo and (ii) a Precedent Agreement for Natural Gas Transportation Service (the “VCP Precedent Agreement”) with Valley Crossing Pipeline, LLC (“VCP”). VCP and, as of the Closing, Rio Bravo are wholly owned subsidiaries of Enbridge Inc. The Valley Crossing Pipeline is owned and operated by VCP.   Pursuant to the RBPL Precedent Agreement, Rio Bravo agreed to provide Rio Grande Gas Supply with firm natural gas transportation services on the Pipeline in a quantity sufficient to match the full operational capacity of each proposed liquefaction train of the Terminal. Rio Bravo’s obligation to construct, install, own, operate and maintain the Pipeline is conditioned on its receipt, no later than December 31, 2023, of notice that Rio Grande Gas Supply or its affiliate has issued a full notice to proceed to the engineering, procurement and construction contractor (the “EPC Contractor”) for the construction of the Terminal. Under the RBPL Precedent Agreement, in consideration for the provision of such firm transportation services, Rio Bravo will be remunerated on a dollar-per-dekatherm, take-or-pay basis, subject to certain adjustments, over a term of at least twenty years, all in compliance with the federal and state authorizations associated with the Pipeline.   Pursuant to the VCP Precedent Agreement, VCP agreed to provide Rio Grande Gas Supply with natural gas transportation services on the Valley Crossing Pipeline in a quantity sufficient to match the commissioning requirements of each proposed liquefaction train of the Terminal. VCP’s obligation to construct, install, own, operate and maintain the necessary interconnection to the Terminal and the Pipeline is conditioned on its receipt, no later than December 31, 2023, of notice that Rio Grande Gas Supply or its affiliate has issued a full notice to proceed to the EPC Contractor for the construction of the Terminal. VCP will be responsible, at its sole cost and expense, to construct, install, own, operate and maintain the tap, riser and valve facilities (the “VCP Transporter Facilities”), which shall connect to Rio Grande Gas Supply’s custody transfer meter and such other facilities as necessary in order for the Terminal to receive gas from the VCP Transporter Facilities (the “Rio Grande Gas Supply Facilities”). Rio Grande Gas Supply will be responsible, at its sole cost and expense, to construct, install, own, operate and maintain the Rio Grande Gas Supply Facilities. Under the VCP Precedent Agreement, in consideration for the provision of the commissioning transportation services, VCP will be remunerated on the same dollar-per-dekatherm, take-or-pay basis as set forth in the RBPL Precedent Agreement for the duration of such commissioning services, all in compliance with the federal and state authorizations associated with the Valley Crossing Pipeline.   If Rio Grande or its affiliate fail to issue a full notice to proceed to the EPC Contractor on or prior to December 31, 2023, Buyer has the right to sell the Equity Interests back to NextDecade LLC and NextDecade LLC has the right to repurchase the Equity Interests from Buyer, in each case at a price not to exceed $ 23 million. Accordingly, the proceeds from the sale of the Equity Interests and additional costs incurred by Buyer are presented as a non-current liability and the assets of Rio Bravo have not been de-recognized in the consolidated balance sheet at December 31, 2020.   38 Table of Contents     Note 6 — Property, Plant and Equipment   Property, plant and equipment consisted of the following (in thousands):       December 31,     December 31,       2020     2019   Fixed Assets                 Computers   $ 487     $ 487   Furniture, fixtures, and equipment     464       471   Leasehold improvements     101       547   Total fixed assets     1,052       1,505   Less: accumulated depreciation     ( 660 )     ( 793 ) Total fixed assets, net     392       712   Terminal and Pipeline Assets (not placed in service)                 Terminal     140,253       121,081   Pipeline     21,017       12,798   Total Terminal and Pipeline assets     161,270       133,879   Total property, plant and equipment, net   $ 161,662     $ 134,591     Depreciation expense for the years ended  December 31, 2020 and 2019 was $ 196 thousand and $ 251 thousand, respectively.     Note 7  — Leases   We currently lease approximately 25,600 square feet of office space for general and administrative purposes in Houston, Texas under a lease agreement that expires on September 30, 2021.   On March 6, 2019, Rio Grande entered into a lease agreement (the “Rio Grande Site Lease”) with the Brownsville Navigation District of Cameron County, Texas (“BND”) pursuant to which it has agreed to lease approximately 984 acres of land situated in Brownsville, Cameron County, Texas for the purposes of constructing, operating, and maintaining the Terminal and gas treatment and gas pipeline facilities.   The initial term of the Rio Grande Site Lease is for 30 years (the “Primary Term”), which will commence on the date specified in a written notice by Rio Grande to BND (the “Effective Date Notice”), if given, confirming that Rio Grande or a Rio Grande affiliate has made a positive FID for the first phase of the Terminal. Under the Rio Grande Site Lease, the Effective Date Notice was to be delivered no later than November 6, 2019 ( the “Outside Effective Date”) unless Rio Grande was unable to deliver the Effective Date Notice prior to the Outside Effective Date due to reasons unrelated to its own acts or omissions or its inability to secure one or more of the required permits for the Terminal. In such a case, the Outside Effective Date would be automatically extended on a month-to-month basis (the “Effective Date Notice Extension Period”). Rio Grande has the option to renew and extend the term of the Rio Grande Site Lease beyond the Primary Term for up to two consecutive renewal periods of ten years each provided that Rio Grande has not caused an event of default under the Rio Grande Site Lease.    On April 30, 2020, Rio Grande and the BND amended the Rio Grande Site Lease (the “Rio Grande Site Lease Amendment”) to extend the effective date for commencing the Rio Grande Site Lease to May 6, 2021 ( the “Effective Date”). The Rio Grande Site Lease Amendment further provides that Rio Grande has the right, exercisable in its sole discretion, to extend the Effective Date to May 6, 2022 by providing the BND with written notice of its election no later than the close of business on the Effective Date.   In January 2017, NextDecade LLC executed surface lease agreements with the City of Texas City and the State of Texas for a 994 -acre site for a potential second U.S. LNG project (collectively, the “Galveston Bay Leases”). The term of the Galveston Bay Leases is 36 months with an option to extend for an additional 12 months.  Such option was included in the measurement of Operating lease right-of-use assets and Operating lease liabilities and was exercised in the fourth quarter of 2019. The Galveston Bay Leases were not renewed upon expiration on December 31, 2020.   In adopting Topic 842, the Company has elected the “package of practical expedients,” which permits it not to reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. The Company also elected the use-of-hindsight and the practical expedient pertaining to land easements. The Company elected not to apply Topic 842 to arrangements with original lease terms of 12 months or less. At lease commencement date, the Company estimated the lease liability and the right-of-use assets at present value, at inception, of $ 2.3 million. On January 1, 2019, upon adoption of Topic 842, the Company recorded right-of-use assets of $ 1.6 million, lease liabilities of $ 1.9 million, eliminated deferred rent of $ 0.1 million and recorded a cumulative-effect adjustment of $ 0.2 million.   The Company determines if a contractual arrangement represents or contains a lease at inception. Operating leases with lease terms greater than twelve months are included in Operating lease right-of-use assets and Operating lease liabilities in the Consolidated Balance Sheets.    Operating lease right-of-use assets and lease liabilities are recognized at the commencement date based on the present value of the future lease payments over the lease term. The Company utilizes its incremental borrowing rate in determining the present value of the future lease payments. The incremental borrowing rate is derived from information available at the lease commencement date and represents the rate of interest that the Company would have to pay to borrow on a collateralized basis over a similar term and amount equal to the lease payments in a similar economic environment. The right-of-use assets and lease liabilities may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The Company has lease arrangements that include both lease and non-lease components. The Company accounts for non-lease components separately from the lease component.   39 Table of Contents   Operating lease right-of-use assets are as follows (in thousands):         December 31,       December 31,         2020       2019   Office leases   $ 429     $ 610   Land leases     —       444   Total operating lease right-of-use assets, net   $ 429     $ 1,054     Operating lease liabilities are as follows (in thousands):         December 31,       December 31,         2020       2019   Office leases   $ 432     $ 698   Land leases     —       —   Total current lease liabilities     432       698   Non-current office leases     —       3   Non-current land leases     —       —   Total lease liabilities   $ 432     $ 701     Operating lease expense is as follows (in thousands):         December 31,       December 31,         2020       2019   Office leases   $ 829     $ 719   Land leases     446       456   Total operating lease expense     1,275       1,175   Short-term lease expense     319       321   Land option expense     9       543   Total land option and lease expense   $ 1,603     $ 2,039     Maturity of operating lease liabilities as of  December 31, 2020 are as follows (in thousands):   2021   $ 452   2022     —   2023     —   2024     —   2025     —   Thereafter     —   Total undiscounted lease payments     452   Discount to present value     ( 20 ) Present value of lease liabilities   $ 432     Other information related to our operating leases as of  December 31, 2020 is as follows (in thousands):         December 31,       December 31,         2020       2019   Cash paid for amounts included in the measurement of operating lease liabilities:                 Cash flows from operating activities   $ 1,004     $ 1,844   Noncash right-of-use assets recorded for operating lease liabilities:                 Adoption of Topic 842     —       1,562   In exchange for new operating lease liabilities during the period     605       443       Note 8  — Other Non-Current Assets   Other non-current assets consisted of the following (in thousands):   December 31,     December 31,       2020     2019   Permitting costs (1)   $ 7,385     $ 2,637   Enterprise resource planning system, net     1,805       3,165   Rio Grande Site Lease initial direct costs     7,109       946   Total other non-current assets, net   $ 16,299     $ 6,748     ( 1 ) Permitting costs primarily represent costs incurred in connection with our permit applications to the United States Army Corps of Engineers and the U.S. Fish and Wildlife Service for wetlands and habitat mitigation measures for potential impacts to wetlands and habitat that may be caused by the construction of the Terminal.   40 Table of Contents     Note 9  — Accrued Liabilities and Other Current Liabilities   Accrued expenses and other current liabilities consisted of the following (in thousands):       December 31,     December 31,       2020     2019   Employee compensation expense   $ 14     $ 4,221   Terminal and Pipeline asset costs     650       2,503   Accrued legal services     5       1,060   Other accrued liabilities     363       967   Total accrued liabilities and other current liabilities   $ 1,032     $ 8,751       Note  10  — Preferred Stock and Common Stock Warrants   Preferred Stock   In August 2018, the Company sold an aggregate of 50,000 shares of Series A Convertible Preferred Stock, par value $ 0.0001 per share (the “Series A Preferred Stock), at $ 1,000  per share for an aggregate purchase price of $ 50 million and issued an additional 1,000 shares of Series A Preferred Stock in aggregate as origination fees to (i) York Capital Management Global Advisors, LLC, severally on behalf of certain funds or accounts managed by it or its affiliates (“York”), (ii) Valinor Management, L.P., severally on behalf of certain funds or accounts for which it is investment manager (“Valinor”), (iii) Bardin Hill Investment Partners LP (formerly known as Halcyon Capital Management LP), severally on behalf of certain funds or accounts managed by it or its affiliates (“Bardin Hill,” and together with York and Valinor, the “Fund Purchasers”) and (iv) HGC NEXT INV LLC (“HGC” and, together with the Fund Purchasers, the “Series A Preferred Stock Purchasers”). Warrants were issued together with the shares of Series A Preferred Stock (the “Series A Warrants”).    In connection with the issuance of Series A Preferred Stock and pursuant to backstop commitment agreements with the Fund Purchasers dated April 11, 2018, as subsequently amended on August 3, 2018 ( as amended, the “Backstop Agreements”), the Company also issued a total of 413,658 shares of Company common stock as fees to the Fund Purchasers.  Each Fund Purchaser is a Company stockholder and, pursuant to that certain Agreement and Plan of Merger, dated as of April 17, 2017, by and among the Company, each Fund Purchaser and/or one or more of its affiliates, and the other parties named therein, three individuals, two individuals, and one individual from York, Valinor, and Bardin Hill, respectively, were appointed to the Company’s board of directors.    In September 2018, the Company sold an aggregate of 29,055 shares of Series B Convertible Preferred Stock, par value $ 0.0001 per share (the “Series B Preferred Stock” and, together with the Series A Preferred Stock, the “Convertible Preferred Stock”), at $ 1,000 per share for an aggregate purchase price of $ 29.055 million and the Company issued an additional 581 shares of Series B Preferred Stock in aggregate as origination fees to certain funds managed by BlackRock, Inc. (“BlackRock”).     In May 2019, the Company sold an aggregate of 20,945 shares of Series B Preferred Stock, at $ 1,000 per share for an aggregate purchase price of $ 20.945 million and we issued an additional 418 shares of Series B Preferred Stock in aggregate as origination fees to York Tactical Energy Fund, L.P. and York Tactical Energy Fund PIV-AN, L.P. (the “York Tactical Funds” and, together with BlackRock, Bardin Hill, Valinor and HGC, the “Series B Preferred Stock Purchasers”), (ii) Bardin Hill, (iii) Valinor and (iv) HGC. Warrants were issued together with the shares of Series B Preferred Stock (the “Series B Warrants” and, together with the Series A Warrants, the “Common Stock Warrants”).   The Company has the option to convert all, but not less than all, of the Convertible Preferred Stock into shares of Company common stock at a strike price of $ 7.34 per share of Company common stock (the “Conversion Price”) on any date on which the volume weighted average trading price of shares of Company common stock for each trading day during any 60 of the prior 90 trading days is equal to or greater than 175 % of the Conversion Price, in each case subject to certain terms and conditions. Furthermore, the Company must convert all of the Convertible Preferred Stock into shares of Company common stock at the Conversion Price on the earlier of (i) ten ( 10 ) business days following a FID Event (as defined in the certificates of designations of the Convertible Preferred Stock) and (ii) the date that is the tenth ( 10th ) anniversary of the closings of the issuances of the Convertible Preferred Stock, as applicable.   The shares of Convertible Preferred Stock bear dividends at a rate of 12 % per annum, which are cumulative and accrue daily from the date of issuance on the $ 1,000 stated value. Such dividends are payable quarterly and may be paid in cash or in-kind. During the  twelve months ended December 31, 2020 and 2019  the Company paid-in-kind $ 14.3 million and $ 11.2  million of dividends, respectively, to holders of the Convertible Preferred Stock. On January 12, 2021, the Company declared dividends to holders of the Convertible Preferred Stock as of the close of business on December 15, 2020. On January 15, 2021, the Company paid-in-kind $ 3.9 million of dividends to holders of the Convertible Preferred Stock.   The holders of Convertible Preferred Stock vote on an “as-converted” basis with the holders of the Company common stock on all matters brought before the holders of Company common stock. In addition, the holders of Convertible Preferred Stock have separate class voting rights with respect to certain matters affecting their rights.   The Convertible Preferred Stock do not qualify as liability instruments under ASC 480, because they are not mandatorily redeemable. However, as SEC Regulation S- X, Rule 5 - 02 - 27 does not permit a probability assessment for a change of control provision, the Convertible Preferred Stock must be presented as mezzanine equity between liabilities and stockholders’ equity in our Consolidated Balance Sheets because a change of control event, could force the Company to redeem the Convertible Preferred Stock for cash or assets of the Company. At each balance sheet date, we must re-evaluate whether the Convertible Preferred Stock continue to qualify for equity classification.   41 Table of Contents   Common Stock Warrants   The Series A Warrants issued to the Series A Preferred Stock Purchasers represent the right to acquire in the aggregate a number of shares of common stock equal to approximately 71 basis points ( 0.71 %) of all outstanding shares of Company common stock, measured on a fully-diluted basis, on the exercise date with a strike price of $ 0.01 per share. The Series B Warrants issued to the Series B Preferred Stock Purchasers represent the right to acquire in the aggregate a number of shares of common stock equal to approximately 71 basis points ( 0.71 %) of all outstanding shares of Company common stock, measured on a fully diluted basis on the exercise date with a strike price of $ 0.01 per share.   The Common Stock Warrants have a fixed three -year term that commenced on the closings of the issuances of the associated Convertible Preferred Stock. The Common Stock Warrants may only be exercised by holders of the Common Stock Warrants at the expiration of such three -year term, except that the Company can force the exercise of the Common Stock Warrants prior to expiration of such term if the volume weighted average trading price of shares of Common Stock for each trading day during any 60 of the prior 90 trading days is equal to or greater than 175% of the of the applicable Convertible Preferred Stock conversion price and, with respect to the Series B Warrants, the Company simultaneously elects to force a mandatory exercise of all other warrants then outstanding and un-exercised and held by any holder of parity stock. Pursuant to ASC 815 - 40 , the fair value of the Common Stock Warrants was recorded as a non-current liability on our Consolidated Balance Sheet on the issuance dates. The Company revalues the Common Stock Warrants at each balance sheet date and recognized a gain of $ 7.9 million and a loss of $ 2.7 million as of December 31, 2020 and 2019 , respectively. The Common Stock Warrant liabilities are included in Level 3 of the fair value hierarchy.   The assumptions used in the Monte Carlo simulation to estimate the fair value of the Common Stock Warrants as of  December 31, 2020 are as follows:       December 31,     December 31,       2020     2019   Stock price   $ 2.09     $ 6.14   Exercise price   $ 0.01     $ 0.01   Risk-free rate     0.1 %     1.6 % Volatility     58.6 %     27.6 % Term (years)     0.8       1.8     Initial Fair Value Allocation   Net proceeds in 2019 were allocated on a fair value basis to the Series B Warrants and on a relative fair value basis to the Series B Preferred Stock.  The allocation of net cash proceeds from the sale of Series B Preferred Stock in 2019  is as follows (in thousands):               Year Ended December 31, 2019                       Series B               Series B     Convertible               Warrants     Preferred   Gross proceeds   $ 20,945                   Equity issuance costs     —                   Net proceeds - Initial Fair Value Allocation   $ 20,945     $ 1,936     $ 19,009   Per balance sheet upon issuance           $ 1,936     $ 19,009     Beneficial Conversion Feature   ASC 470 - 20 - 20 – Debt – Debt with conversion and Other Options (“ASC 470 - 20” ) defines a BCF as a nondetachable conversion feature that is in the money at the issuance date. The Company was required by ASC 470 - 20 to allocate a portion of the proceeds from the Series A Preferred Stock equal to the intrinsic value of the BCF to additional paid-in capital. The intrinsic value of the BCF is calculated at the issuance date as the difference between the “accounting conversion price” and the market price of shares of Company common stock multiplied by the number of shares of Company common stock into which the Series A Preferred Stock is convertible. The accounting conversion prices of $ 5.58 per share and $ 6.24 per share for the Fund Purchasers and HGC, respectively, is different than the initial conversion price of $ 7.50 per share. The “accounting conversion price” is derived by dividing the proceeds allocated to the Series A Preferred Stock by the number of shares of Company common stock into which the Series A Preferred Stock is convertible. We are recording the accretion of the $ 2.5 million Series A Preferred Stock discount attributable to the BCF as a deemed dividend using the effective yield method over the period prior to the expected conversion date.   42 Table of Contents     Note  11  — Net Loss Per Share Attributable to Common Stockholders   The following table (in thousands, except for loss per share) reconciles basic and diluted weighted average common shares outstanding for the years ended December 31, 2020 and 2019 :       Year Ended       December 31,       2020     2019   Weighted average common shares outstanding:                 Basic     117,524       109,057   Dilutive unvested stock, convertible preferred stock, Common Stock Warrants and IPO Warrants     —       —   Diluted     117,524       109,057                     Basic and diluted net loss per share attributable to common stockholders   $ ( 0.24 )   $ ( 0.45 )   Potentially dilutive securities that were not included in the diluted net loss per share computations because their effect would have been anti-dilutive were as follows (in thousands):       Year Ended       December 31,       2020     2019   Unvested stock (1)     916       861   Convertible preferred stock     16,635       13,697   Common Stock Warrants     1,976       1,662   IPO Warrants (2)     12,082       12,082   Total potentially dilutive common shares     31,609       28,302       ( 1 ) Does not include 2.1 million shares and 3.6 million shares of unvested stock for the year ended  December 31, 2020 and 2019 because the performance conditions had not yet been satisfied as of   December 31, 2020 and 2019 , respectively.   ( 2 ) The IPO Warrants were issued in connection with our initial public offering and are exercisable at a price of $ 11.50 per share and expire July 24, 2022. The Company may redeem the Warrants at a price of $ 0.01 per IPO Warrant upon 30 days’ notice only if the last sale price of our common stock is at least $ 17.50 per share for any 20 trading days within a 30 -trading day period. If the Company redeems the IPO Warrants in this manner, the Company will have the option to do so on a cashless basis with the issuance of an economically equivalent number of shares of Company common stock.   43 Table of Contents         Note 12 — Share-based Compensation   We have granted shares of Company common stock and restricted stock to employees, consultants and non-employee directors under our 2017 Omnibus Incentive Plan (the “2017 Plan”) and in connection with the special meeting of stockholders on July 24, 2017.   Total share-based compensation consisted of the following (in thousands):       Year Ended       December 31,       2020     2019   Share-based compensation:                 Equity awards   $ ( 155 )   $ ( 8,525 ) Liability awards     —       —   Total share-based compensation     ( 155 )     ( 8,525 ) Capitalized share-based compensation     ( 186 )     ( 1,121 ) Total share-based compensation expense   $ ( 341 )   $ ( 9,646 )   On January 1, 2019, we adopted Accounting Standards Update (“ASU”) 2018 - 07, Compensation-Stock Compensation (“ASU 2018 - 07” ). This standard simplifies aspects of share-based compensation issued to non-employees by making the guidance consistent with accounting for employee share-based compensation. Upon adoption of this standard, we reclassified $ 2.1 million from Share-based compensation liability to Additional paid-in-capital in our Consolidated Balance Sheets.   Certain employee contracts provided for cash bonuses upon a positive FID in the Terminal (the “FID Bonus”). In January 2018, the Compensation Committee (formerly the Nominating, Corporate Governance and Compensation Committee) of the board of directors approved, and certain employees party to such contracts accepted, an amendment to such contracts whereby the FID Bonuses would be settled in shares of Company common stock equal to 110 % of the FID Bonus. The associated liability for FID Bonuses to be settled in shares of Company common stock of $ 0.2  million is included in share-based compensation liability in our Consolidated Balance Sheets at each of  December 31, 2020 and 2019 .   The total unrecognized compensation costs at  December 31, 2020 relating to equity-classified awards were $ 3.1 million, which is expected to be recognized over a weighted average period of 1.0 years.   Restricted stock awards are awards of Company common stock that are subject to restrictions on transfer and to a risk of forfeiture if the recipient’s employment with the Company is terminated prior to the lapse of the restrictions. Restricted stock awards vest based on service conditions and/or performance conditions. The amortization of the value of restricted stock grants is accounted for as a charge to compensation expense, or capitalized, depending on the nature of the services provided by the employee, with a corresponding increase to additional-paid-in-capital over the requisite service period.   Grants of restricted stock to employees, non-employees and non-employee directors that vest based on service and/or performance conditions are measured at the closing quoted market price of our common stock on the grant date.    The table below provides a summary of our restricted stock outstanding as of  December 31, 2020 and changes during the year ended  December 31, 2020 (in thousands, except for per share information):       Shares     Weighted Average Grant Date Fair Value Per Share   Non-vested at January 1, 2020     4,772     $ 7.95   Granted     225       3.02   Vested     ( 612 )     5.38   Forfeited     ( 874 )     8.08   Non-vested at December 31, 2020     3,511     $ 8.05     44 Table of Contents     Note  13  — Income Taxes   The reconciliation of the federal statutory income tax rate to our effective income tax rate is as follows:       Year Ended       December 31,       2020     2019   U.S. federal statutory rate, beginning of year     21 %     21 % Officers' compensation     2       7   Other     ( 3 )     ( 2 ) Valuation allowance     ( 20 )     ( 26 ) Effective tax rate as reported     — %     — %   Significant components of our deferred tax assets and liabilities at  December 31, 2020 and 2019 are as follows (in thousands):       Year Ended       December 31,       2020     2019   Deferred tax assets                 Net operating loss carryforwards and credits   $ 20,698     $ 15,064   Share-based compensation expense     3,813       3,441   Property, plant and equipment     725       1,025   Common stock warrant liabilities     —       524   Operating lease liabilities     91       147   Other     54       21   Less: valuation allowance     ( 22,669 )     ( 19,802 ) Total deferred tax assets     2,712       420                     Deferred tax liabilities                 Common stock warrant liabilities     ( 1,129 )     —   Operating lease Right-of-use assets     ( 1,583 )     ( 420 ) Total deferred tax liabilities     ( 2,712 )     ( 420 )                   Net deferred tax assets (liabilities)   $ —     $ —     The federal deferred tax assets presented above do not include the state tax benefits as our net deferred state tax assets are offset with a full valuation allowance.   At December 31, 2020 , we had federal net operating loss (“NOL”) carryforwards of approximately $ 98.6  million. Approximately $ 26.1 million of these NOL carryforwards will expire between 2034 and 2038.   Due to our history of NOLs, current year NOLs and significant risk factors related to our ability to generate taxable income, we have established a valuation allowance to offset our deferred tax assets as of December 31, 2020 and 2019 . We will continue to evaluate our ability to release the valuation allowance in the future. Due to our full valuation allowance, we have not recorded a provision for federal or state income taxes during the years ended  December 31, 2020 or 2019 .  Deferred tax assets and deferred tax liabilities are classified as non-current in our Consolidated Balance Sheets.   The Tax Reform Act of 1986 (as amended) contains provisions that limit the utilization of NOL and tax credit carryforwards if there has been a change in ownership as described in Section  382 of the Internal Revenue Code (“Section 382” ).  Substantial changes in the Company's ownership have occurred that may limit or reduce the amount of NOL carryforwards that the Company could utilize in the future to offset taxable income. The Company has not completed a detailed Section  382 study at this time to determine what impact, if any, that ownership changes may have had on its NOL carryforwards.  In each period since its inception, the Company has recorded a valuation allowance for the full amount of its deferred tax assets, as the realization of the deferred tax asset is uncertain. As a result, the Company has not recognized any federal or state income tax benefit in its Consolidated Statement of Operations.   We remain subject to periodic audits and reviews by taxing authorities; however, we did not have any open income tax audits as of December 31, 2020. The federal tax returns for the years beginning 2015 remain open for examination.   In response to the global pandemic related to COVID- 19, the President signed into law the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) on March 27, 2020 and the Consolidated Appropriations Act, 2021 (the “CAA”) on December 27, 2020.  The CARES Act and the CAA provide numerous relief provisions for corporate taxpayers, including modification of the utilization limitations on NOLs, favorable expansions of the deduction for business interest expense under Internal Revenue Code Section 163 (j), and the ability to accelerate timing of refundable alternative minimum tax credits.  For the year ended December 31, 2020, there were no material tax impacts to our consolidated financial statements from the CARES Act, the CAA or other COVID- 19 measures.  The Company continues to monitor additional guidance issued by the U.S. Treasury Department, the Internal Revenue Service and others.   45 Table of Contents     Note  14  — Commitments and Contingencies   Other Commitments   On March 6, 2019, Rio Grande entered into a lease agreement (the “Rio Grande Site Lease”) with the Brownsville Navigation District of Cameron County, Texas (“BND”) for the lease by Rio Grande of approximately 984 acres of land situated in Brownsville, Cameron County, Texas for the purposes of constructing, operating, and maintaining (i) a liquefied natural gas facility and export terminal and (ii) gas treatment and gas pipeline facilities. On April 30, 2020, Rio Grande and the BND amended the Rio Grande Site Lease (the “Rio Grande Site Lease Amendment”) to extend the effective date for commencing the Rio Grande Site Lease to May 6, 2021 ( the “Effective Date”). The Rio Grande Site Lease Amendment further provides that Rio Grande has the right, exercisable in its sole discretion, to extend the Effective Date to May 6, 2022 by providing the BND with written notice of its election no later than the close of business on the Effective Date.   In connection with the Rio Grande Site Lease Amendment, Rio Grande is committed to pay approximately $ 1.5 million per quarter to the BND through the earlier of the Effective Date and lease commencement.   Obligation under LNG Sale and Purchase Agreement   In March 2019, we entered into a 20 -year sale and purchase agreement (the “SPA”) with Shell NA LNG LLC (“Shell”) for the supply of approximately two million tonnes per annum of liquefied natural gas from the Terminal. Pursuant to the SPA, Shell will purchase LNG on a free-on-board (“FOB”) basis starting from the date the first liquefaction train of the Terminal that is commercially operable, with approximately three -quarters of the purchased LNG volume indexed to Brent and the remaining volume indexed to domestic United States gas indices, including Henry Hub.   In the first quarter of 2020, pursuant to the terms of the SPA, the SPA became effective upon the conditions precedent in the SPA being satisfied or waived. The SPA obligates Rio Grande to deliver the contracted volumes of LNG to Shell at the FOB delivery point, subject to the first liquefaction train at the Terminal being commercially operable.   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. We regularly analyze current information and, as necessary, provide accruals for liabilities we deem probable and estimable.   As of December 31, 2020 , management was not aware of any claims or legal actions 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 event will not occur.     Note 15 — Recent Accounting Pronouncements    The following table provides a brief description of recent accounting standards that have not been adopted by the Company during the reporting period:   Standard   Description   Date of Adoption   Effect on our Consolidated Financial Statements or Other Significant Matters ASU 2020 - 06,   Accounting for Convertible Instruments and Contracts in Entity's Own Equity (Subtopic 815 - 40 )   This standard requires entities to provide expanded disclosures about the terms and features of convertible instruments. For convertible instruments, the instruments primarily affected are those issued with beneficial conversion features or cash conversion features because the accounting models for those specific features are removed.   January 1, 2022   We are currently evaluating the effect of this standard on our Consolidated Financial Statements.     Note 16  — Subsequent Events   On March 17, 2021, the Company entered into a Series C Convertible Preferred Stock Purchase Agreement (collectively, the “Series C Stock Purchase Agreements”) with each of (i) York Capital Management, L.P. and certain of its affiliates (“York”), (ii) certain affiliates of Bardin Hill Investment Partners LP (“Bardin Hill”), and (iii) Avenue Energy Opportunities Fund II, L.P (“Avenue” and together with York and Bardin Hill, the “Purchasers”) pursuant to which the Company agreed to sell, and the Purchasers agreed to purchase shares of the Company’s Series C Convertible Preferred Stock, par value $ 0.0001 per share (the “Series C Preferred Stock”), together with associated warrants, for an aggregate purchase price of $ 24.5  million.  The consummation of the transactions contemplated by the Series C Stock Purchase Agreements occurred at multiple closings on or prior to March 22, 2021.   We have evaluated subsequent events through March 25, 2021, the date the financial statements were issued.  Any material subsequent events that occurred during this time have been properly recognized and/or disclosed in these financial statements.   46 Table of Contents       NextDecade Corporation and Subsidiaries Supplemental Information to Consolidated Financial Statements Summarized Quarterly Financial Data (unaudited)   Summarized Quarterly Financial Data – (in thousands, except per share amounts)       First     Second     Third     Fourth       Quarter     Quarter     Quarter     Quarter   Year ended December 31, 2020:                                 Revenues   $ —     $ —     $ —     $ —   Total operating loss     (7,241 )     (5,211 )     (5,557 )     (4,003 ) Net loss attributable to common stockholders     (2,617 )     (9,304 )     (10,807 )     (6,056 ) Basic and diluted loss per share (1)     (0.02 )     (0.08 )     (0.09 )     (0.05 )                                   Year ended December 31, 2019:                                 Revenues   $ —     $ —     $ —     $ —   Total operating loss     (12,488 )     (5,582 )     (4,412 )     (12,519 ) Net loss attributable to common stockholders     (17,566 )     (7,207 )     (6,362 )     (17,417 ) Basic and diluted loss per share (1)     (0.16 )     (0.07 )     (0.06 )     (0.16 )     (1) The sum of the quarterly basic and diluted loss per share may not equal the full year amount as the computation of the weighted average common shares outstanding for basic and diluted shares outstanding for each quarter and the full year are performed independently.   47 Table of Contents     Item 9. Changes in and Disagreements with Accountants   None.   Item 9A. Controls and Procedures   Evaluation of Disclosure Controls and Procedures   Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures.   Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of “our disclosure controls and procedures,” as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the fiscal year ended December 31, 2020. Based on this evaluation, our principal executive officer and principal financial officer have concluded that, as of December 31, 2020, our disclosure controls and procedures were effective.   Management’s Report on Internal Controls Over Financial Reporting   As management, we are responsible for establishing and maintaining adequate internal control over financial reporting for the Company. In order to evaluate the effectiveness of internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act of 2002, we have conducted an assessment, including testing using the criteria in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). The Company’s system of internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements and, even when determined to be effective, can only provide reasonable assurance with respect to financial statement preparation and presentation.   Based on our assessment, we have concluded that the Company maintained effective internal control over financial reporting as of December 31, 2020, based on criteria in Internal Control—Integrated Framework (2013) issued by the COSO.   The Company is neither an accelerated filer nor a large accelerated filer, as defined in Rule 12b-2 under the Exchange Act and, therefore, this Annual Report on Form 10-K does not include an audit report on internal control over financial reporting by the Company’s registered public accounting firm. Management’s report on internal control over financial reporting for the year ended December 31, 2020 was not required to be attested by the Company’s registered public accounting firm pursuant to Item 308(b) of Regulation S-K.   Changes in Internal Control over Financial Reporting   During the most recent fiscal quarter, there were no changes in internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.   Item 9B.     Other Information   None.   48 Table of Contents     Part III   Pursuant to paragraph 3 of General Instruction G to Form 10-K, the information required by Items 10 through 14 of Part III of this Report is incorporated by reference from NextDecade’s definitive proxy statement, which is to be filed pursuant to Regulation 14A of the Exchange Act within 120 days after the end of NextDecade’s fiscal year ended December 31, 2020.   49 Table of Contents     Part IV   Item 15.     Exhibit and Financial Statement Schedules   (a) Financial Statements, Schedules and Exhibits     (1) Financial Statements – NextDecade Corporation and Subsidiaries:   Report of Independent Registered Public Accounting Firm 29 Consolidated Balance Sheets 31 Consolidated Statements of Operations  32 Consolidated Statements of Stockholders’ Equity 33 Consolidated Statements of Cash Flows 34 Notes to Consolidated Financial Statements 35 Supplemental Information to Consolidated Financial Statements – Summarized Quarterly Financial Data 47     (2) Financial Statement Schedules:   All schedules are omitted because they are not applicable or the required information is shown in the financial statements or the notes thereto.     (3) Exhibits:   Exhibit No.      Description 3.1 (1)   Second Amended and Restated Certificate of Incorporation of NextDecade Corporation, dated July 24, 2017 3.2 (2)   Amended and Restated Bylaws of NextDecade Corporation, dated July 24, 2017 3.3 (3)   Certificate of Designations of Series A Convertible Preferred Stock, dated August 9, 2018 3.4 (4)   Certificate of Designations of Series B Convertible Preferred Stock, dated September 28, 2018 3.5 (5)   Certificate of Designations of Series C Convertible Preferred Stock dated March 17, 2021 3.6 (6)   Certificate of Amendment to Certificate of Designations of Series A Convertible Preferred Stock, dated July 12, 2019 3.7 (7)   Certificate of Amendment to Certificate of Designations of Series B Convertible Preferred Stock, dated July 12, 2019 3.8 (8)   Certificate of Increase to Certificate of Designations of Series A Convertible Preferred Stock of NextDecade Corporation, dated July 15, 2019 3.9 (9)   Certificate of Increase to Certificate of Designations of Series B Convertible Preferred Stock of NextDecade Corporation, dated July 15, 2019 3.10 (10)   Amendment No. 1 to the Amended and Restated Bylaws of NextDecade Corporation 4.1 (11)   Specimen Common Share Certificate 4.2 (12)   Specimen  IPO Warrant Certificate 4.3 (13)   Form of Warrant Agreement between Harmony Merger Corp. and Continental Stock Transfer & Trust Company 4.4 (14)   Form of Warrant Agreement for the Series A Warrants 4.5 (15)   Form of Warrant Agreement for the Series B Warrants 4.6 (16)   Form of Warrant Agreement for the Series C Warrants 4.7 (17)   Description of Common Stock of NextDecade Corporation Registered Pursuant to Section 12 of the Securities Exchange Act of 1934   50 Table of Contents   10.1 (18)†   Employment Agreement, dated September 8, 2017, between NextDecade Corporation and Matthew K.
