In addition to the solicitation of proxies by use of the Proxy Statement, the Company’s directors, officers and employees may solicit the return of proxies by mail, personal interview, or the Internet. Such directors, officers and employees will not receive additional compensation for their solicitation efforts, but they will be reimbursed for any out-of-pocket expenses incurred.

PROXY STATEMENT

April 25, 2024

General Information

This Proxy Statement is furnished in connection with the solicitation of proxies by the board of directors (the “Board”) of NextDecade Corporation (the “Company”) for the Annual Meeting of Stockholders to be held on June 3, 2024 at 9:00 a.m. Central Time and any postponement(s) or adjournment(s) thereof (the “Annual Meeting”). The Annual Meeting is a virtual meeting at www.proxydocs.com/NEXT. This Proxy Statement and the accompanying Notice of Annual Meeting and proxy card are first being sent to stockholders on or about May 3, 2024.

Virtual Annual Meeting

The Annual Meeting will be a completely virtual meeting. There will be no physical meeting location. The Annual Meeting will only be conducted via live webcast.

In order to attend the Annual Meeting, you must register in advance at www.proxydocs.com/NEXT prior to the deadline of May 30, 2024 at 4:00 p.m. Central Time. Upon completing your registration, you will receive further instructions via email, including your unique link that will allow you access to the Annual Meeting and you will have the ability to submit questions. Please be sure to follow instructions found on your proxy card and subsequent instructions that will be delivered to you via email.

Record Date and Voting Securities

Holders of record of common stock, par value $0.0001 per share (the “Common Stock”), as of the close of business on April 18, 2024 (the “Record Date”), are entitled to receive notice of and to vote at the Annual Meeting. As of the Record Date, there were 257,904,371 shares of Common Stock issued and outstanding and entitled to vote at the Annual Meeting. Holders of record of shares of Common Stock are entitled to one vote for each share of Common Stock owned by them as of the Record Date.

Stockholders that are entitled to vote at the Annual Meeting may do so electronically at the Annual Meeting or by proxy submitted by mail or Internet as described on the proxy card accompanying this Proxy Statement. Stockholders may also submit their voting instructions by telephone as described on the proxy card.

Abstentions and broker non-votes are counted for purposes of determining the presence or absence of a quorum for the transaction of business. Broker non-votes occur when a broker or other nominee does not have discretionary authority to vote the shares with respect to a particular matter and has not received voting instructions from the beneficial owner with respect to that matter.

The affirmative majority of the votes cast in person or by proxy at the Annual Meeting is required for the election of directors, which means that the number of votes cast “For” a director’s election must exceed the number of votes cast “Against” such director's election. Thus, broker non-votes and abstentions will have no effect on the election of directors.

The proposal related to the amendment of the Company’s 2017 Omnibus Incentive Plan, as amended (“Proposal 2”), the proposal regarding the advisory vote on compensation paid to the Company’s named executive officers (“Proposal 3”) and the proposal seeking ratification of the appointment of KPMG LLP as the Company’s independent registered public accountants and auditors for 2024 (“Proposal 4”) each requires the affirmative vote of a majority of the shares of Common Stock present in person or by proxy at the Annual Meeting and entitled to vote thereon.

Abstentions will have the same effect as a vote against Proposal 2, Proposal 3 and Proposal 4. Broker non-votes will have no effect on Proposal 2 or Proposal 3. The Company expects no broker non-votes on Proposal 4.

1

There are no cumulative voting rights in the election of directors or any other matter being voted upon and appraisal rights are not applicable to the matters being voted upon.

Attendance

Only stockholders of record or beneficial owners of Common Stock as of the Record Date may attend the Annual Meeting. Even if you plan to attend the Annual Meeting, the Company recommends that you also submit your voting instructions by proxy as described in this Proxy Statement so that your vote will be counted if you later decide not to attend the Annual Meeting.

Quorum

Except as may be otherwise required by law, the Certificate of Incorporation or the Company’s Amended and Restated Bylaws, as amended (the “Bylaws”), the holders of a majority of the shares of Common Stock issued and outstanding and entitled to vote and present at the Annual Meeting or represented by proxy shall constitute a quorum at a meeting of the stockholders. The person or persons whom the Company appoints to act as inspector(s) of election will determine whether a quorum exists. Shares of Common Stock represented by properly executed and returned proxies will be treated as present. Shares of Common Stock present or represented at the Annual Meeting that abstain from voting or that are the subject of broker non-votes will be counted as present for purposes of determining a quorum.

How Your Proxy Will be Voted on Actions to be Taken

The Board is soliciting a proxy in the enclosed form to provide you with an opportunity to vote on matters scheduled to come before the Annual Meeting whether or not you attend the Annual Meeting.

Granting Your Proxy

If you properly execute and return a proxy in the enclosed form, your shares of Common Stock will be voted as you specify. If you make no specifications, your proxy representing shares of Common Stock will be voted:

•“FOR” each of the proposed director nominees;

•“FOR” adoption of the amendment to the Company’s 2017 Omnibus Incentive Plan, as amended (the “2017 Equity Plan”);

•“FOR” approval, on a non-binding, advisory basis, of the compensation of the Company’s named executive officers; and

•“FOR” the ratification of the reappointment of independent registered public accountants and auditors.

The Company expects no matters to be presented for action at the Annual Meeting other than the items described in this Proxy Statement. By signing and returning the proxy, however, you will give to the persons named as proxies therein discretionary voting authority with respect to any other matter that may properly come before the Annual Meeting, and they intend to vote on any such other matter in accordance with their best judgment.

Revoking Your Proxy

If you submit a proxy, you may subsequently revoke it or submit a revised proxy at any time before it is voted. You may also attend the Annual Meeting and vote electronically at the Annual Meeting, which would cancel any proxy that you previously submitted. If you wish to vote at the Annual Meeting but hold your shares of Common Stock in street name (that is, in the name of a broker, bank or other institution), then you must have a proxy from the broker, bank or institution in order to vote at the Annual Meeting.

Proxy Solicitation

The Company will pay all expenses of soliciting proxies for the Annual Meeting. In addition to solicitations by mail, arrangements have been made for brokers and nominees to send proxy materials to their principals, and the Company will reimburse them for their reasonable expenses. The Company may have its employees or other representatives (who will receive no additional compensation for their services) solicit proxies by telephone, telecopy, personal interview or other means. The Company may choose to engage a paid proxy solicitor to solicit proxies for the Annual Meeting but have not yet done so.

Stockholder Proposals

If you want to nominate a director or present a proposal or other business before the Annual Meeting, you must deliver notice to the Company’s Corporate Secretary at NextDecade Corporation, 1000 Louisiana Street, Suite 3300, Houston, Texas 77002 no later than the close of business on the tenth (10th) day following the date of this Proxy Statement in accordance with the Bylaws. The notice must comply in all respects with the Bylaws, as amended, which were previously filed as Exhibit 3.2 to the Company's Annual Report on Form 10-K for the year ended December 31, 2023.

If you want the Company to consider including a proposal or nominee in next year’s proxy statement, you must deliver it in writing to the Corporate Secretary, NextDecade Corporation, 1000 Louisiana Street, Suite 3300, Houston, Texas 77002, no later than January 4, 2025.

If you want to present a proposal or other business at next year’s Annual Meeting of Stockholders in person, you must submit it in writing to the Corporate Secretary, at the above address, no later than the close of business on the tenth (10th) day following the date of the proxy statement for next year’s Annual Meeting of Stockholders to be considered timely, in accordance with the specific procedural requirements set forth in the Bylaws. If you would like to review the procedural and timing requirements relating to stockholder proposals, please contact the Corporate Secretary for a copy of the Bylaws or view them on the SEC's website at www.sec.gov.

In addition to satisfying the foregoing requirements under the Bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) no later than April 4, 2025.

Pursuant to the rules of the Exchange Act, the designated proxies may use discretionary authority to vote with respect to stockholder proposals presented in person at the Annual Meeting if the stockholder making the proposal has not given the Company timely notice of such proposal.

Delivery of One Proxy Statement and Annual Report to a Single Household to Reduce Duplicate Mailings

The Company is required to send to each stockholder of record a proxy statement and to arrange for a proxy statement to be provided to each beneficial stockholder whose shares of Common Stock are held by or in the name of a broker, bank, trust or other nominee. Because some stockholders hold shares of Common Stock in multiple accounts, this process results in duplicate mailings of proxy statements to stockholders who share the same address. Stockholders may avoid receiving duplicate mailings and save the Company the cost of producing and mailing duplicate documents as follows:

Stockholders of Record

If your shares of Common Stock are registered in your own name and you are interested in consenting to the delivery of a single proxy statement, you may contact the Company by mail at 1000 Louisiana Street, Suite 3300, Houston, Texas 77002, by telephone at (713) 574-1880 or by e-mail at corporatesecretary@next-decade.com.

Beneficial Stockholders

If your shares of Common Stock are not registered in your own name, your broker, bank, trust or other nominee that holds your shares of Common Stock may have asked you to consent to the delivery of a single proxy statement if there are other Company stockholders who share an address with you. If you currently receive more than one proxy statement at your household and would like to receive only one copy of each in the future, you should contact your nominee.

Right to Request Separate Copies

If you consent to the delivery of a single proxy statement but later decide that you would prefer to receive a separate copy of the proxy statement for each stockholder sharing your address, then please notify the Company or your nominee, as applicable, and the Company or they will promptly deliver such additional proxy statements. If you wish to receive a separate copy of the proxy statement for each stockholder sharing your address in the future, you may contact the Company by mail at 1000 Louisiana Street, Suite 3300, Houston, Texas 77002, by telephone at (713) 574-1880 or by e-mail at corporatesecretary@next-decade.com.

PROPOSAL NO. 1 – ELECTION OF DIRECTORS

Currently, the Board consists of ten members. The Certificate of Incorporation and the Bylaws provide that the Board be classified into three classes. These classes are designated as Class A directors, Class B directors and Class C directors, with members of each class holding office for staggered three-year terms. Newly created directorships or vacancies on the Board resulting from death, resignation, disqualification, removal or other causes may be filled by the affirmative vote of a majority of the remaining directors then in office, even if less than a quorum of the Board is present, or by a sole remaining director. Each such director so chosen shall hold office until the Company’s next annual meeting of stockholders or until such director’s successor is duly elected and qualified or until such director’s earlier death, resignation or removal in accordance with the Bylaws.

There are currently four Class A directors, three Class B directors and three Class C directors. Each of the Class A directors has a term that expires at the Annual Meeting. Additionally, Timothy Wyatt, a Class B director, has a term that expires at the Annual Meeting because he was appointed to the Board on January 25, 2024 and pursuant to the Bylaws, directors appointed to fill vacancies shall hold office until the Company's next annual meeting of stockholders, which, in his case, is the Annual Meeting. If Mr. Wyatt is elected by the stockholders at the Annual Meeting, Mr. Wyatt will serve the remainder of his term as a Class B director until the 2025 Annual Meeting of Stockholders or until his successor is duly elected and qualified or until his earlier death, resignation or removal in accordance with the Bylaws.

Director Nominees and Terms

The Board has nominated for election Matthew Schatzman, Thibaud de Préval, Avinash Kripalani and William Vrattos, each a Class A director, and Timothy Wyatt, a Class B director. Each of the director nominees is currently on the Board and has indicated his willingness to serve, if elected, but if any should be unable or unwilling to serve, proxies may be voted for a substitute nominee designated by the Board. If elected at the Annual Meeting, (i) each of Messrs. Schatzman, de Préval, Kripalani and Vrattos will serve as a Class A director until the 2027 Annual Meeting of Stockholders, subject to the election and qualification of their successors and to their earlier death, resignation or removal in accordance with the Bylaws, and (ii) Mr. Wyatt will serve as a Class B director until the 2025 Annual Meeting of Stockholders or until his successor is duly elected and qualified or until his earlier death, resignation or removal in accordance with the Bylaws.

See “Director Nomination Process” below for additional information on the nomination of directors.

If any nominee should be unavailable for election as a result of an unexpected occurrence, the Board’s proxies shall vote such shares for the election of such substitute nominee as the Board may propose. It is not anticipated that any nominee will be unable or unwilling to serve as a director if elected.

The names, ages as of April 18, 2024, principal occupations, and other information highlighting the particular experience, qualifications, attributes and skills that support the recommendation of the Nominating and Corporate Governance Committee (the “NCG Committee”) that each of the director nominees be nominated for election at the Annual Meeting are set forth below.

Matthew K. Schatzman, 58, is the Company’s Chief Executive Officer and has served in such position since February 2018. Mr. Schatzman has served as a member of the Board since September 2017 and, in June 2019, Mr. Schatzman was appointed Chairman of the Board. From September 2017 until his appointment as Chairman of the Board, Mr. Schatzman served as the Company’s President. Prior to joining the Company, Mr. Schatzman served as President at MKS Energy, LLC, an advisory and consulting firm focused on LNG, natural gas and crude oil markets, logistics and risk management from March 2017 until September 2017. He was previously Executive Vice President, Global Energy Marketing and Shipping at BG Group, plc (“BG Group”), a British multinational oil and gas company, from January 2012 until May 2014 and served as Senior Vice President, Energy Marketing from March 2007 until December 2011.

The Board believes Mr. Schatzman’s marketing, logistics, risk management and operational leadership experience of over three decades with companies in the LNG, natural gas, oil and power generation industries, including BG Group and Dynegy, make him well-qualified to serve as the Company’s Chairman and Chief Executive Officer.

Vote Required for Approval

The affirmative vote of a majority of the votes cast at the Annual Meeting in person or by proxy is required for the election of directors, which means that the number of votes cast “For” a director’s election must exceed the number of votes cast “Against” such director's election.

The Board unanimously recommends that the stockholders vote “FOR” the election of each of the Class Adirector nominees and the Class B director nominee.

Incumbent Class BDirectors

Corporate Governance

Role of the Board

The Board oversees the Chief Executive Officer and other members of senior management in the management of the Company’s business and affairs. The Company’s key governance documents, including the Company’s Second Amended and Restated Corporate Governance Guidelines (the “Corporate Governance Guidelines”), may be found on

7

the “Corporate Governance” page under the “Investors” section of our corporate website, www.next-decade.com. The governance structure is designed to foster principled actions, effective decision-making, and appropriate monitoring of compliance and performance. The Board met 14 times during 2023.

Each of our directors attended or participated in at least 75% of the meetings of the Board and the respective committees on which he is a member held during the period such director was a director during the fiscal year ended December 31, 2023.

Although we do not have a formal policy regarding attendance by members of the Board at annual meetings of stockholders, we encourage, but do not require, our directors to attend. Four of the Company’s directors attended our last annual meeting of stockholders.

Board Leadership Structure

The Board does not have a policy requiring the combination or separation of leadership positions and the Company’s governing documents do not mandate a particular structure. This provides the Board with the flexibility to select its leadership structure, from time to time, based on the criteria that it deems in the best interests of the Company and its stockholders. The Board recognizes that the leadership structure and the combination or separation of the Chief Executive Officer and the Chairman positions are driven by the Company’s needs at any point in time.

Currently, the Chief Executive Officer and Chairman positions are held by Mr. Schatzman. The Company also has a Lead Independent Director, William Vrattos, who was appointed by the Board as Lead Independent Director in April 2020. The Lead Independent Director has broad responsibility and authority, including to:

•preside at all meetings of the Board at which the Chairman is not present, including executive sessions of the independent directors;

•call meetings of independent directors;

•serve as the principal liaison between the Chairman and the independent directors;

•approve all information sent to the Board, including the quality, quantity, appropriateness and timeliness of such information;

•retain outside advisors and consultants who report directly to the Board on Board-wide issues;

•on an annual basis, review his responsibility and authority and recommend to the Board for approval any modifications or changes; and

•perform such other duties as the Board may delegate from time to time.

The Board has determined that its current structure, with combined Chief Executive Officer and Chairman roles and a Lead Independent Director, is in the best interests of the Company and its stockholders at this time. A number of factors support a combined Chief Executive Officer and Chairman role, counterbalanced by a Lead Independent Director, including, among others:

•the Chief Executive Officer has extensive knowledge of all aspects of the Company and its business and risks, its industry and its customers;

•the Chief Executive Officer is intimately involved in the day-to-day operations of the Company and is best positioned to elevate the most critical business issues for consideration by the Board;

•the Board believes the Chief Executive Officer serving in both capacities allows him to more effectively execute the Company’s strategic initiatives and business plans and confront its challenges;

•a combined Chief Executive Officer and Chairman role provides the Company with decisive and effective leadership with clearer accountability to the Company’s stockholders;

•the combined role is both counterbalanced and enhanced by the effective oversight and independence of the Board and the leadership provided by the Lead Independent Director and committee chairs;

8

•the Board believes that the appointment of a strong Lead Independent Director and the use of regular executive sessions of the non-management directors, along with all directors being independent except for the Chief Executive Officer, allow it to maintain effective oversight of management; and

•in the Board’s view, splitting the Chief Executive Officer and Chairman roles could potentially make our management and governance processes less effective through undesirable duplication of work and possibly lead to a blurring of clear lines of accountability and responsibility.

The Board periodically reviews the leadership structure to determine whether it continues to best serve the Company and its stockholders.

Board Role in Risk Oversight

Risk is inherent in any business, and the Company’s management is responsible for the day-to-day management of risks that the Company faces. The Board, on the other hand, has responsibility for the oversight of risk management. In its risk oversight role, the Board has the responsibility to evaluate the risk management process to ensure its adequacy and that it is implemented properly by management.

The Board believes that full and open communication between management and the Board is essential for effective risk management and oversight. The Board meets regularly with senior management, including the executive officers, to discuss strategy and risks facing the Company. Senior management attends the quarterly meetings of the Board, as well as certain committee meetings, in order to address any questions or concerns raised by directors on risk management and any other matters. Each quarter, or more frequently if the business requires, the Board receives presentations from senior management on business operations, financial results and strategic issues.

The Board is also assisted by committees in fulfilling its oversight responsibilities in certain areas of risk, as described further under the section below titled “Committees of the Board.” All of the committees report back to the full Board as to the committees’ activities and matters discussed and reviewed at the committees’ meetings.

Independence of Directors

The Company adheres to the Nasdaq listing rules in determining whether a director is independent. The Board consults with its counsel to ensure that the Board’s determinations are consistent with such rules and all relevant securities and other laws and regulations regarding the independence of directors. The Nasdaq listing rules generally define an “independent director” as a person, other than an executive officer of a company or any other individual having a relationship which, in the opinion of the Board, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

The Board undertook a review of the independence of our directors and considered whether any director has a material relationship with us that could compromise his ability to exercise independent judgment in carrying out his responsibilities. The Board considered the relationships that each director has with us and all other facts and circumstances the Board deemed relevant in determining his independence. Based upon information requested from and provided by each director concerning his background, employment, affiliations and stock ownership, the Board has determined that each of Sir Frank and Messrs. Belke, de Préval, Kripalani, Oddo, Scoggins, Vrattos, Wells and Wyatt is independent under the Nasdaq listing rules.

Mr. Schatzman is not an independent director under the Nasdaq listing rules because he currently serves as the Chief Executive Officer of the Company.

Board Observers

Pursuant to that certain Purchaser Rights Agreement between the Company and certain funds managed by BlackRock Inc. (the “Purchasers”), dated September 28, 2018, the holders of a majority of the shares of Common Stock issued upon conversion of the Series B Preferred Stock that are held by BlackRock Financial Management Inc., BlackRock Inc., a Purchaser or any of their respective affiliates (collectively, the “BlackRock Parties”) have the collective right to designate in writing a representative to attend all meetings of the Board and any committee thereof in a nonvoting observer capacity (the “BlackRock Observer”). The BlackRock Observer will serve until such person is replaced by a subsequent representative designated in writing by the BlackRock Parties or until the BlackRock Parties, by notice to the Company, relinquish their collective right to designate a person to serve as the BlackRock Observer.

9

In July 2020, upon his resignation from the Board, Eric S. Rosenfeld was designated as a Board observer who serves at the pleasure of the Board.

Pursuant to letter agreements executed in connection with the final investment decision (“FID”) on our Rio Grande LNG export facility (the “Rio Grande LNG Facility”), each of Global Infrastructure Partners and GIC have the right to designate a representative to attend all meetings of the Board and any committee thereof in a nonvoting observer capacity.

Director Nomination Process

Each year, the Board proposes a slate of director nominees to stockholders for election at the annual meeting of stockholders. Stockholders may also recommend candidates for election to the Board, as described below. The Board has delegated the process of screening potential director candidates to the NCG Committee. The NCG Committee is responsible for reviewing with the Board the appropriate criteria that directors are required to fulfill (including experience, qualifications, attributes, skills and other characteristics) in the context of the current make-up of the Board and the needs of the Board given the circumstances of the Company. In identifying and screening director candidates, the NCG Committee considers whether the candidates fulfill the criteria for directors approved by the Board. Such criteria include integrity, objectivity, independence, sound judgment, leadership, courage, and diversity of experience. While the NCG Committee does not have a formal policy concerning the diversity of the Board, the NCG Committee considers diversity of race, ethnicity, gender, age, cultural background and professional experience in evaluating candidates for Board membership.

Diversity is one of NextDecade’s core values. We believe it takes people with different strengths, ideas and cultural backgrounds to make our company succeed. The achievement of FID on the Rio Grande LNG Facility was a transformative event for our company in many respects. Thereafter, the NCG Committee initiated a process to identify the optimal qualifications, attributes, skills and other characteristics, including race, ethnicity, gender and cultural backgrounds, that our Board would optimally include and does not currently possess. Our current Board includes one individual of Asian ethnicity and does not include a female director, but we are optimistic that the completion of this process and a corresponding director search will result in a Board with both broader expertise and enhanced demographic and gender diversity.

The following matrix displays the demographic and gender diversity characteristics of our Board, including the director nominees:

Board Diversity Matrix (As of April 18, 2024)
Total Number of Directors		10
	Female		Male
Part I: Gender Identity
Directors	0		10
Part II: Demographic Background
Asian	0		1
White	0		9

The NCG Committee values the input of stockholders in identifying director candidates. Accordingly, although the NCG Committee does not have a specific policy with regard to the consideration of candidates recommended by stockholders, the NCG Committee considers recommendations for Board candidates submitted by stockholders using substantially the same criteria it applies to recommendations from the NCG Committee, directors and members of management. Any such nominations should be submitted to the NCG Committee by mail in care of the Company’s Corporate Secretary, at 1000 Louisiana Street, Suite 3300, Houston, Texas 77002 and be accompanied by information required by the Bylaws and, if applicable, by Rule 14a-19 under the Exchange Act. The written recommendation should be submitted within the timeframe described in the Bylaws or as required by Rule 14a-19, as described under the caption “Stockholder Proposals” above, and comply with other specific procedural requirements set forth in the Bylaws and Rule 14a-19, as applicable. If you would like to review the procedural and timing requirements relating to director nominations, please contact the Corporate Secretary for a copy of the Bylaws or view them on the SEC's website at www.sec.gov.

The NCG Committee is currently comprised of Sir Frank and Messrs. Oddo, Scoggins, Vrattos, and Wells. The NCG Committee operates under a written charter adopted by the Board.

The Board has determined each director currently serving on the NCG Committee qualifies as an independent director under the Nasdaq listing rules. The NCG Committee met once in 2023.

•Performance-based: tied to the execution of the strategic plan and achievement of key development milestones.

•Stockholder-aligned: compensation outcomes aligned with stockholders’ experience and value creation.

•Retentive: support the retention and engagement of top leadership talent.

16

•Competitive: total compensation opportunities that attract and retain top talent in a highly competitive market.

•Flexible: allow for flexibility given the Company’s development phase and needs.

•Clear: transparent with respect to compensation levels, opportunities and structure.

•Compliant: compensation supports efficient cost management (accounting, cash flow, share usage), adheres to regulatory requirements and governance standards and is tied to credible metrics and goals.

During 2023, no material changes were implemented to the annual target compensation of NEOs, but some business event related payments were made. Key compensation decisions for 2023 are summarized below:

•Cash target compensation was not increased from the levels established as of September 1, 2022.

•Awarded an FID cash bonus in recognition of the achievement of a critical business milestone.

•The annual long-term incentive stock grant kept the 2022 design. Absolute and relative total shareholder return (“TSR”) metrics were kept in the 2023 performance-based long-term incentive awards to keep incentivizing stockholder value creation and enhancing NEOs’ alignment with stockholders’ interests.

•Granted long-term performance awards to our NEOs designed to promote retention for project delivery and business continuity post-FID of an additional train.

•Awarded annual bonus payouts in accordance with the overall organization’s achievements in 2023. In determining the 2023 annual bonus payout, the Compensation Committee considered the following business priorities and achievements: the FID on Trains 1-3 of the Rio Grande LNG Facility and related commercialization and project financing; the successful launch and execution of the Rio Grande LNG Facility construction within established scheduled and cost structure; the continuous evolution of the Carbon Solutions business; and the progress toward successful approval of Train 4 of the Rio Grande LNG Facility.

2023 Equity Compensation

During 2023, our named executive officers were granted three types of restricted stock units under the 2017 Equity Plan, each of which entitles the recipient to receive one share of the Company’s common stock upon satisfaction of the relevant conditions established pursuant to the applicable award.

Project-Based Incentive Awards

To incentivize delivery of a critical milestone in development strategy, NEOs received performance-based restricted stock units (“T4 PSUs”), which will become earned upon achievement of a positive final investment decision for a fourth liquefaction train of RGLNG (the “T4 FID Milestone”). 50% of the T4 PSUs will vest upon the T4 FID Milestone, with the remaining 50% of the T4 PSUs vesting ratably on the first and second anniversaries of the T4 FID Milestone.

Annual Equity Awards

As part of the evolution of our compensation programs, we adopted an annual cadence and design for our annual equity awards to better reflect our anticipated transition to the operating phase of our strategy. The annual equity awards are intended to maintain alignment between NEO compensation and stockholders’ interests and deliver competitive total compensation opportunities for our NEOs. The 2023 annual equity awards were comprised of:

•time-based restricted stock units (“RSUs”), which vest ratably over a three-year period, with one third of the RSUs granted to an individual vesting on the successive anniversaries of the grant date, and

•TSR-based restricted stock units (the “TSR PSUs”), which will become earned and vest based on achievement of TSR criteria over the period beginning on September 1, 2023 and ending August 31, 2026 (the “Performance Period”). The maximum payout for the TSR PSUs granted in 2023 is capped at 100% of target.

17

75% of each NEO’s TSR PSUs are subject to achievement of an absolute stock price factor, to be calculated using the volume weighted average trading price per share of the Company’s common stock for the final twenty trading days of the Performance Period as follows, with the vesting percentage determined based on linear interpolation if the ending stock price falls between two thresholds:

Ending Stock Price	Vesting Percentage
$20.00	100%
$17.00	75%
$13.50	50%
$11.00	25%
Less than $11.00	0%

The remaining 25% of each NEO’s TSR PSUs are subject to achievement of a relative total shareholder return factor over the Performance Period compared to a peer group (the “Performance Peer Group”). Under such awards, total shareholder return will be calculated as the ratio of (i) the ending stock price, plus any dividends or distributions on a per share basis, to (ii) the beginning stock price, with the ending stock price and beginning stock price each calculated based on the volume-weighted average trading price for the twenty trading days immediately preceding the relevant measurement date. The Performance Peer Group was selected by the Compensation Committee based in part on analysis by the Company’s independent compensation consultant, Meridian Compensation Partners, LLC, and consists of Antero Midstream Corporation, Cheniere Energy, Inc., DT Midstream, Inc., Enlink Midstream, LLC, Equitrans Midstream Corporation, Excelerate Energy, Inc., Genesis Energy, L.P., New Fortress Energy, Inc., Tellurian Inc. and Western Midstream Partners, LP. The portion of the TSR PSUs subject to relative total shareholder return criteria will vest as follows:

Relative Total Shareholder Return Percentile	Vesting Percentage
50% Percentile or above	100%
25% Percentile or above	50%
Below 25% Percentile	0%

The following table provides the aggregate equity awards granted to our NEOs during 2023:

Name	T4 PSUs	RSUs	TSR PSUs
Matthew Schatzman	707,325	370,675	370,675
Brent Wahl *	235,775	123,558	123,558
Vera de Gyarfas	157,183	82,372	82,372

*Mr. Wahl also received a grant of 35,007 RSUs on July 12, 2023 which were immediately vested. This grant was made pursuant to performance objectives established at his date of hire in 2019, which was to be settled after a positive FID.

The Company expects to continue to utilize restricted stock units as a key, long-term component of executive compensation going forward, in amounts and subject to the conditions to be established by the Compensation Committee. The Company may also, from time to time, grant additional, similar time-based or performance-based awards to its employees, which may include its executive officers, with different vesting schedules or performance criteria, as appropriate, in any given year based on performance, retention needs or other factors that the Compensation Committee deems relevant.

Overview of Compensation for Matthew K. Schatzman, Chairman of the Board and Chief Executive Officer

Mr. Schatzman has served as Chief Executive Officer of the Company since February 2018. In June 2019, Mr. Schatzman was appointed Chairman of the Board. From September 2017 until his appointment as Chairman of the Board, Mr. Schatzman served as the Company’s President. The Employment Agreement, initially dated as of September 18, 2017 and as amended, by and between the Company and Mr. Schatzman (as amended, the “Schatzman Employment Agreement”) provided for a term through June 30, 2022 and will be automatically extended for additional one-year periods unless and until the Company or Mr. Schatzman gives to the other written notice at least one-hundred and eighty (180) days prior to the applicable renewal date of a decision not to renew for an additional year. As of the

18

date of this proxy statement, the term of the Schatzman Employment Agreement is currently extended through June 30, 2025.

Effective September 1, 2022, the Board approved an increase in Mr. Schatzman’s annual base salary from $650,000 to $750,000 and an increase in his target annual bonus from 110% of annual base salary to 120% of annual base salary to position Mr. Schatzman's total compensation closer to market. There was no change to Mr. Schatzman's base salary or target compensation during 2023.

The Schatzman Employment Agreement also provides that if the Company at any time terminates Mr. Schatzman’s employment without Cause (as defined in the Schatzman Employment Agreement), or elects not to renew the Schatzman Employment Agreement by providing timely notice, or if Mr. Schatzman voluntarily terminates his employment with Good Reason (as defined in the Schatzman Employment Agreement), Mr. Schatzman will be entitled to (i) a lump sum cash payment equal to 12 months of his then current base salary and (ii) a pro-rata portion of his annual bonus for the fiscal year in which the termination occurs (based on an amount equal to his then applicable annual bonus target percentage multiplied by his then applicable base salary, prorated for his service prior to termination).

The Schatzman Employment Agreement also provides that Mr. Schatzman is eligible for health insurance and disability insurance and other customary employee benefits. The Schatzman Employment Agreement also contains customary non-competition and non-solicitation covenants and covenants regarding the treatment of confidential information.

Termination and Change in Control

The Schatzman Employment Agreement provides for the payment of certain severance benefits upon termination. The award agreements governing restricted stock units granted to our NEOs generally provide that such restricted stock will fully vest upon a change of control of the Company only if either (i) the award recipient's employment is terminated as a result of such change of control or (ii) the applicable award is not assumed, or replaced with an award of substantially equivalent value, by the acquirer.

Pension/Retirement Benefits

The Company does not provide a qualified defined benefit pension plan or any non-qualified supplemental executive retirement benefits to any of its executive officers or directors. However, eligible executive officers and directors participate in a defined contribution retirement plan (the “401(k) Plan”) which allows them to contribute up to 100% of their compensation up to the maximum permitted by the Internal Revenue Code. In 2023, following FID, the Company began matching employee contributions, with matching contributions in respect of 2023 employee contributions first made in 2024. None of the NEOs received a match during 2023. The 401(k) Plan is sponsored and maintained by the Company.

Additional Benefit Programs

Certain officers and directors, including the NEOs, are entitled to the following benefits: parking, health insurance, life insurance and accidental death and dismemberment.

(1)The PEO for 2023, 2022 and 2021 is Matthew K. Schatzman. The non-PEO named executive officers for 2023 and 2022 are Brent E. Wahl and Vera de Gyarfas. The non-PEO named executive officers for 2021 are Brent E. Wahl and Ivan Van der Walt, our former Chief Operating Officer.

(2)The amounts shown as Compensation Actually Paid have been calculated in accordance with Item 402(v) of Regulation S-K and do not reflect compensation actually realized or received by the Company’s named executive officers. These amounts reflect total compensation as set forth in the Summary Compensation Table for each year, adjusted as described in footnote 3 below and averaged for the non-PEO named executive officers.

(3)Compensation Actually Paid reflects the exclusions and inclusions for the PEO and, on average, the non-PEO named executive officers set forth below. Amounts excluded, which are set forth in the “Minus Stock Awards from Summary Compensation Table” columns below, represent the Stock Awards reported in the “Stock Awards” column of the Summary Compensation Table for each applicable year. Amounts added back to determine Compensation Actually Paid are made up of the following components which are set forth in the table below, as applicable: (i) the fair value as of the end of the fiscal year of outstanding and unvested equity awards granted in that year; (ii) the change in fair value during the year of equity awards granted in prior years that remained outstanding and unvested at the end of the year; (iii) the fair value as of the vesting date of equity awards that were granted and vested in that year; and (iv) the change in fair value during the year through the vesting date of equity awards granted in prior years that vested during that year. The fair value at the end of the prior year of awards granted in any prior year that failed to meet applicable vesting conditions during the covered year are subtracted, although there were no such awards for the PEO or the non-PEO named executive officers in 2021, 2022 or 2023. The dollar value of any dividends or other earnings paid on stock awards in a covered fiscal year prior to the vesting date that are not otherwise included in the total compensation for the covered fiscal year are added, although there were no such payments for the PEO or the non-PEO named executive officers in 2021, 2022 or 2023. Equity values are calculated in accordance with ASC Topic 718.

Description of the Information Presented in the Pay Versus Performance Table

As described in greater detail above in this proxy statement, the Company’s executive compensation program reflects a pay-for-performance philosophy. While the Company aligns executive compensation with Company performance by providing for compensation outcomes aligned with significant value creation events, not all of such events are measures presented in the Pay Versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align Company performance measures with compensation that is actually paid (as computed in accordance with Item 402(v) of Regulation S-K) for a particular fiscal year. Compensation actually paid is influenced by numerous factors, including but not limited to the timing of new grant issuances and outstanding grant vesting, share price volatility during the fiscal year, and many other factors. In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions for the relationships between information represented in the Pay Versus Performance table.

Description of Relationship Between Named Executive Officer Compensation Actually Paid and Company Total Shareholder Return

The following chart sets forth the relationship between Compensation Actually Paid to our PEO, the average of Compensation Paid to our Non-PEO named executive officers, and the Company’s TSR over the fiscal three-year period from 2021 through 2023.

Description of Relationship Between Named Executive Officer Compensation Actually Paid and Net Loss

The following chart sets forth the relationship between Compensation Actually Paid to our PEO, the average of Compensation Actually Paid to our non-PEO named executive officers, and the Company’s net loss over the fiscal three-year period from 2021 through 2023.

2017 Equity Plan

On December 15, 2017, the Company’s stockholders approved the 2017 Equity Plan and the 2017 Equity Plan became effective by its terms on such date. On June 15, 2020, the Company’s stockholders approved an amendment to the 2017 Equity Plan to increase the amount of awards thereunder that can be granted to the Company’s non-employee directors in any calendar year. On June 15, 2021, the Company's stockholders approved an amendment to the 2017 Equity Plan to increase the maximum number of shares available thereunder and remove certain individual limits on shares issuable under such plan during a calendar year. On June 22, 2022 and June 1, 2023, the Company’s stockholders approved amendments to increase the maximum number of shares of Common Stock that may be delivered pursuant to awards granted under the 2017 Equity Plan.

The purpose of the 2017 Equity Plan is to further align the interests of eligible participants with those of the Company’s stockholders by providing long-term incentive compensation opportunities tied to the performance of the Company and its Common Stock. Persons eligible to receive awards under the 2017 Equity Plan include our employees, non-employee members of the Board, consultants, or other personal service providers of the Company or any of its subsidiaries. Currently, the 2017 Equity Plan authorizes the issuance of up to 24,262,461 shares of Common Stock, subject to certain adjustments under the 2017 Equity Plan. Awards covering 5,786,917 shares of Common Stock were granted under the 2017 Equity Plan during the fiscal year 2023.

Narrative Discussion

In 2019, the Board, following its review of an analysis performed by the Company’s independent compensation consultant, Meridian Compensation Partners, LLC, on the recommendation of the Compensation Committee, adopted a director compensation policy (the “Director Compensation Policy”) designed to provide a total compensation package that enables the Company to attract and retain, on a long-term basis, highly qualified At-large Directors.

Under the Director Compensation Policy, during 2023, each At-large Director was paid an annual cash retainer of $80,000 (the “Annual Board Cash Retainer”), which At-large Directors may elect to receive in the form of shares of restricted stock in lieu of cash, and an annual cash retainer of $15,000 for each committee of the Board of which such director serves as the chairperson, except that the chairperson of the Audit Committee is entitled to receive an annual cash retainer of $20,000. Mr. Belke and Mr. Scoggins elected to receive stock in lieu of the annual cash

26

retainer in respect of 2023 compensation. The annual cash retainers are prorated for partial years of service. In addition, under the Director Compensation Policy, each At-large Director was granted, in one or more installments, a number of shares of Common Stock equal to $120,000 divided by the closing price of the Common Stock on Nasdaq on the date of such grant (the “Annual Board Grant”) or, if such grant date was not a trading day, then the last trading day occurring prior to such grant date. The awards of shares of restricted Common Stock to be issued will be prorated based on the actual days of service on the Board and the terms and conditions of such awards, including vesting terms and transferability, will be as set forth in the Company’s standard award agreement, in the form adopted from time to time by the Board or the Compensation Committee, provided, that all such awards shall vest during the year in which they are granted. The shares of Common Stock issued under the Director Compensation Policy are issued under and subject to the 2017 Equity Plan or any successor plan. There are no per meeting attendance fees for At-large Directors for attending Board meetings. Each director of the Company, including Board observers, are entitled to receive reimbursement of all reasonable out-of-pocket expenses incurred in connection with attending meetings of the Board. Such reimbursement is in addition to the compensation provided for the Director Compensation Policy.

Effective January 1, 2024, the Board, following a recommendation from the Compensation Committee and after analysis of a selected group of energy and general industry companies’ director compensation programs performed by the Company’s independent compensation consultant, Meridian Compensation Partners, LLC, amended the Director Compensation Policy to (i) increase the Annual Board Cash Retainer from $80,000 to $100,000, (ii) increase the value of the Annual Board Grant from $120,000 to $125,000 and (iii) cause the Annual Board Grant to vest on the first anniversary of grant date.

The Company adopted a stock ownership policy for At-large Directors in December 2019. Pursuant to such policy, At-large Directors are expected to own a number of shares of Common Stock equal to five times the Annual Board Cash Retainer divided by the closing price of the Common Stock on Nasdaq on the date of calculation. The number of shares of Common Stock to be held by At-large Directors will be calculated on the first trading day of each calendar year based on such shares’ fair market value. Each At-large Director is expected to satisfy the stock ownership requirement within three years of the date such individual became subject to the policy or the date of any increase in the Annual Board Cash Retainer. Effective January 1, 2024, the Board amended the stock ownership policy to extend the time period an individual has to satisfy the stock ownership requirement from three years to five years.

PROPOSAL NO. 2 – APPROVAL OF AN AMENDMENTTO THE 2017 EQUITY PLAN

The Board is asking you to approve an amendment to the 2017 Equity Plan (the “Equity Plan Amendment”) to increase the maximum number of shares of Common Stock that may be delivered pursuant to awards granted under the 2017 Equity Plan from 24,262,461 to 29,262,461 (all of which may be granted as incentive stock options). On December 15, 2017, the Company’s stockholders approved the 2017 Equity Plan, and the 2017 Equity Plan became effective by its terms on such date. On June 15, 2020, the Company’s stockholders approved an amendment to the 2017 Equity Plan to increase the amount of awards thereunder that can be granted to the Company’s non-employee directors in any calendar year. On June 15, 2021, the Company’s stockholders approved an amendment to the 2017 Equity Plan to increase the maximum number of shares of Common Stock that may be delivered pursuant to awards granted under the 2017 Equity Plan and to remove a provision limiting the number of shares of Common Stock subject to certain types of awards issued to any one participant during a calendar year. On June 22, 2022 and June 1, 2023, the Company’s stockholders approved amendments to increase the maximum number of shares of Common Stock that may be delivered pursuant to awards granted under the 2017 Equity Plan.

On April 16, 2024, the Board approved the Equity Plan Amendment, subject to approval by the Company’s stockholders. A copy of the Equity Plan Amendment has been included as Appendix A to this Proxy Statement, which was also filed electronically with the SEC and can be reviewed on the SEC’s website at www.sec.gov.

As of April 18, 2024, 2,861,866 shares remain available for future issuance under the 2017 Equity Plan. The Company believes long-term equity compensation furthers its compensation objectives of aligning the interests of its officers, directors and employees with those of its stockholders, encouraging long-term performance and rewarding award recipients for creating stockholder value. Accordingly, the Board has approved and is asking you to approve the Equity Plan Amendment to increase the maximum number of shares of Common Stock that may be delivered pursuant to awards granted under the 2017 Equity Plan from 24,262,461 to 29,262,461 (all of which may be granted as incentive stock options). If stockholders do not approve the Equity Plan Amendment, our ability to recruit, retain and incentivize the highly skilled talent (including continuing employees and non-employee members of our Board) critical to successfully compete and grow our business could be seriously and negatively impacted. In addition, we would have to consider other compensation alternatives, which may not as effectively align the interests of our employees with those of our stockholders, and would be a distraction from our management team’s focus on execution of our business strategy. For example, we would have to consider increasing cash compensation, which could adversely affect our business, results of operations, financial condition and cash flows.

Key Plan Attributes

The 2017 Equity Plan contains, and after the Equity Plan Amendment will continue to contain, several features designed to protect shareholder interests and to reflect our compensation principles and practices, including:

•Sets a fixed number of shares authorized for issuance, requiring stockholder approval for any increases;

•No “evergreen” share provisions;

•No granting of discounted options or stock appreciation rights ("SARs") (except for substitute awards granted in connection with acquisitions);

•No repricing of a stock option or stock appreciation right without prior stockholder approval;

•No liberal share counting or “recycling” of shares that have been used to cover taxes or the purchase price of shares related to an award;

•No excise tax-gross ups on change in control;

•Broad discretion to determine the treatment of awards on a change in control; and

•Permits clawback of benefits upon certain events, including restatements and bad acts during and after service.

Material Terms of the 2017 Equity Plan (including after the Equity Plan Amendment)

The material terms of the 2017 Equity Plan, including the proposed amendments described above, are summarized below. This summary of the 2017 Equity Plan is not intended to be a complete description of the 2017 Equity Plan and is qualified in its entirety by the actual text of the 2017 Equity Plan (previously filed as Exhibit 10.2 to the Company’s Annual Report on Form 10-K for the year ended December 31, 2023).

Eligible Persons

Persons eligible to receive awards under the 2017 Equity Plan include our employees, non-employee members of the Board, consultants, or other personal service providers of the Company or any of its subsidiaries. The Administrator (as defined below) determines from time to time the participants to whom awards will be granted. As of December 31, 2023, approximately 142 employees, four At-large Directors, and seven consultants and other personal service providers of the Company and its subsidiaries were eligible to participate in the 2017 Equity Plan on the basis that, if granted awards under the 2017 Equity Plan, their interests would be further aligned with those of the Company’s stockholders.

Administration

The Board or one or more committees appointed by the Board administer the 2017 Equity Plan. For this purpose, the Board has delegated general administrative authority for the 2017 Equity Plan to the Compensation Committee. The Compensation Committee may delegate certain limited award grant authority to one or more officers of the Company, subject to the requirements of Section 157(c) of the Delaware General Corporation Law (or any successor provision). The appropriate acting body, be it the Board, a committee within its delegated authority, or an officer within his or her delegated authority, is referred to in this summary as the “Administrator.” The Administrator determines the number of shares of Common Stock that are subject to awards and the terms and conditions of such awards, including the price (if any) to be paid for the shares of Common Stock or the award. Along with other authority granted to the Administrator under the 2017 Equity Plan, the Administrator may (i) determine the recipients of awards, (ii) prescribe the restrictions, terms and conditions of all awards, (iii) interpret the 2017 Equity Plan and terms of the awards, (iv) adopt rules for the administration, interpretation and application of the 2017 Equity Plan as are consistent therewith, and interpret, amend or revoke any such rules, (v) make all determinations with respect to a participant’s service and the termination of such service for purposes of any award, (vi) correct any defect(s) or omission(s) or reconcile any ambiguity(ies) or inconsistency(ies) in the 2017 Equity Plan or any award thereunder, (vii) make all determinations it deems advisable for the administration of the 2017 Equity Plan, (viii) decide all disputes arising in connection with the 2017 Equity Plan and to otherwise supervise the administration of the 2017 Equity Plan, (ix) subject to the terms of the 2017 Equity Plan, amend the terms of an award in any manner that is not inconsistent with the 2017 Equity Plan, (x) accelerate the vesting or, to the extent applicable, exercisability of any award at any time (including, but not limited to, upon a change of control or upon termination of service under certain circumstances, as set forth in the award agreement or otherwise), and (xi) adopt such procedures, modifications or subplans as are necessary or appropriate to permit participation in the 2017 Equity Plan by eligible persons who are foreign nationals or employed outside of the United States.

Incentive Awards

The 2017 Equity Plan authorizes stock options, stock appreciation rights, restricted stock, restricted stock units, cash performance awards as well as other awards (described in the 2017 Equity Plan) that are responsive to changing developments in management compensation. The 2017 Equity Plan retains the flexibility to offer competitive incentives and to tailor benefits to specific needs and circumstances. An option or SAR will expire no later than ten years from the date of grant. Awards will vest in accordance with the schedule set forth in the applicable award agreement.

Stock Option. A stock option is the right to purchase shares of Common Stock at a future date at a specified price per share at least equal to the fair market value of a share of Common Stock on the date of grant (except for substitute awards granted in connection with acquisitions). An option may either be an Incentive Stock Option (“ISO”) or a nonstatutory stock option (“NSO”). ISO benefits are taxed differently from NSOs, as described under “Material U.S. Federal Income Tax Consequences,” below. ISOs also are subject to more restrictive terms and are limited in amount by the Code, and the 2017 Equity Plan. Full payment for shares of Common Stock purchased on the exercise of any option must be made at the time of such exercise in a manner approved by the Administrator. Payment of the exercise price may be made: (i) in cash or by cash equivalent acceptable to the Administrator, or, (ii) to the extent permitted by the Administrator in its sole discretion in an award agreement or otherwise (A) in shares of Common

29

Stock valued at the fair market value of such shares on the date of exercise, (B) through an open-market, broker-assisted sales transaction pursuant to which the Company is promptly delivered the amount of proceeds necessary to satisfy the exercise price, (C) by reducing the number of shares of Common Stock otherwise deliverable upon the exercise of the stock option by the number of shares of Common Stock having a fair market value on the date of exercise equal to the exercise price, (D) by a combination of the methods described above or (E) by such other method as may be approved by the Administrator and set forth in the award agreement. The Administrator will, in its discretion, prescribe in an award agreement the time or times at which or the conditions upon which, a stock option or portion thereof will become vested and/or exercisable. The requirements for vesting and exercisability of a stock option may be based on the continued service of the participant with the Company or a subsidiary for a specified time period (or periods) and/or on such other terms and conditions as approved by the Administrator in its discretion. If the vesting requirements of a stock option are not satisfied, then the unvested portion of the award will be forfeited. Subject to the anti-dilution adjustment provisions contained in the 2017 Equity Plan, without the prior approval of the Company’s stockholders, neither the Administrator nor the Board may cancel a stock option when the exercise price per share exceeds the fair market value of one share of Common Stock in exchange for cash or another award (other than in connection with a change of control (as defined in the 2017 Equity Plan) or cause the cancellation, substitution or amendment of a stock option that would have the effect of reducing the exercise price of such a stock option previously granted under the 2017 Equity Plan or otherwise approve any modification to such a stock option, that would be treated as a “repricing” under the then applicable rules, regulations or listing requirements adopted by the Nasdaq or other principal exchange on which the Common Stock is then listed. Dividend equivalent rights may be granted with respect to the shares of Common Stock subject to a stock option to the extent permitted by the Administrator and set forth in the award agreement.

SARs. A SAR is the right to receive payment of an amount equal to the excess of the fair market value of a share of Common Stock on the date of exercise of the SAR over the base price of the SAR. The base price will be established by the Administrator at the time of grant of the SAR but will not be less than the fair market value of a share of Common Stock on the date of grant (except for substitute awards granted in connection with acquisitions). SARs may be granted in connection with other awards or independently. The Administrator will in its discretion provide in an award agreement the time or times at which or the conditions upon which a SAR or portion thereof will become vested and/or exercisable. The requirements for vesting and exercisability of a SAR may be based on the continued service of a participant with the Company or a subsidiary for a specified time period (or periods) and/or on such other terms and conditions as approved by the Administrator in its discretion. If the vesting requirements of a SAR are not satisfied, then the unvested portion of the award will be forfeited. Subject to the anti-dilution adjustment provisions contained in the 2017 Equity Plan, without the prior approval of the Company’s stockholders, neither the Administrator nor the Board will cancel a SAR when the base price per share exceeds the fair market value of one share of Common Stock in exchange for cash or another award (other than in connection with a change of control) or cause the cancellation, substitution or amendment of a SAR that would have the effect of reducing the base price of such a SAR previously granted under the 2017 Equity Plan or otherwise approve any modification to such SAR that would be treated as a “repricing” under the then applicable rules, regulations or listing requirements adopted by the Nasdaq or other principal exchange on which the Common Stock is then listed. Dividend equivalent rights may be granted with respect to the shares of Common Stock subject to a SAR to the extent permitted by the Administrator and set forth in the award agreement.

Restricted Stock. A restricted stock award is typically for a fixed number of shares of Common Stock subject to restrictions. The Administrator specifies the price, if any, the participant must pay for such shares and the restrictions (which may include, for example, continued service and/or performance standards) imposed on such shares. The number of shares awarded in connection with a restricted stock award shall be determined by the Administrator. The requirements for vesting of a restricted stock award may be based on the continued service of the participant with the Company or a subsidiary for a specified time period (or periods) and/or on such other terms and conditions as approved by the Administrator in its discretion. If the vesting requirements of a restricted stock award are not satisfied, then the unvested portion of the award will generally be forfeited and the shares of Common Stock subject to the award will be returned to the Company. Subject to the provisions on restricted stock awards set forth in the 2017 Equity Plan and the applicable award agreement, the participant will have all rights of a stockholder with respect to the shares granted to the participant under a restricted stock award unless the Administrator determines otherwise. The Administrator has discretion to determine the timing of payment of dividends and distributions to the participant.

Restricted Stock Units. A restricted stock unit is a contractual right representing notional unit interests equal in value to a share of Common Stock to be paid or distributed at such times, and subject to such conditions, as determined by the Administrator. The value of each restricted stock unit is equal to the fair market value of a share of Common Stock on the applicable date or time period of determination, as specified by the Administrator. Restricted stock units will be subject to such restrictions and conditions as the Administrator will determine. The requirements for vesting of a restricted stock unit may be based on the continued service of the participant with the Company or a subsidiary for a

30

specified time period (or periods) and/or on such other terms and conditions as approved by the Administrator in its discretion. If the vesting requirements of a restricted stock unit award are not satisfied, then the unvested portion of the award will be forfeited. Restricted stock units will become payable to a participant at the time or times determined by the Administrator and set forth in the award agreement, which may be upon or following the vesting of the award. Payment of a restricted stock unit may be made, as approved by the Administrator and set forth in the award agreement, in cash or in shares of Common Stock or in a combination thereof. Restricted stock units may be granted together with a dividend equivalent right with respect to the shares of Common Stock subject to the restricted stock unit. Generally, any payments made pursuant to dividend equivalent rights will be paid at such times as determined by the Administrator in its discretion.

Cash Performance Awards. A cash performance award means an award that is denominated by a cash amount to a participant and payable based on or conditioned upon the attainment of pre-established business and/or individual performance goals over a specified performance period. A cash performance award may be granted to any participant selected by the Administrator. The requirements for payment may be also based upon the continued service of the participant with the Company or a subsidiary during the respective performance period and on such other conditions as determined by the Administrator and set forth in the award agreement.

Stock Awards. The Administrator may grant other stock awards, which may be granted for past services, in lieu of bonus or other cash compensation, as directors’ compensation or for any other valid purpose as determined by the Administrator. Subject to the 2017 Equity Plan and the applicable award agreement, upon the issuance of shares of Common Stock under a stock award, the participant will have all rights of a stockholder with respect to the shares of Common Stock.

Authorized Shares; Lapsed Awards;Substitute Awards

A total of 24,262,461 shares of Common Stock have been authorized by the stockholders for issuance under the 2017 Equity Plan. A description of the remaining shares of Common Stock available for award under the 2017 Equity Plan is contained in the section above titled “Executive Compensation—Equity Compensation Plan Information.” If the Equity Plan Amendment is approved by the stockholders, an additional 5,000,000 shares of Common Stock will be authorized for issuance under the 2017 Equity Plan, all of which may be granted as ISOs. If any outstanding award under the 2017 Equity Plan is canceled, expired, forfeited, surrendered, terminated or settled by delivery of fewer shares of Common Stock than the number underlying an applicable award, the shares of Common Stock subject to the cancelled, expired, forfeited, surrendered, terminated, or settled without payment portion of the award will be added to the maximum number of shares of Common Stock authorized under the 2017 Equity Plan. Notwithstanding the foregoing, shares of Common Stock that are (i) withheld from an award in payment of the exercise, base or purchase price or taxes relating to such an award, or (ii) not issued or delivered as a result of the net settlement of an outstanding stock option or SAR under the 2017 Equity Plan, as applicable, will not be available for future awards under the 2017 Equity Plan. The last reported trading price per share of the Common Stock on the Nasdaq Capital Market on April 22, 2024 was $6.20. The 2017 Equity Plan provides that no non-employee director may be granted, during any calendar year, awards having a fair value (determined on the date of grant) that exceeds $300,000 when added to all cash compensation paid to the non-employee director during the same calendar year. Nothing contained in the 2017 Equity Plan will be construed to limit the right of the Administrator to grant awards under the 2017 Equity Plan in connection with the acquisition, whether by purchase, merger, consolidation or other corporate transaction, of the business or assets of any corporation or other entity. Without limiting the foregoing, the Administrator may grant awards under the 2017 Equity Plan to an employee or director of another corporation who becomes eligible to participate in the 2017 Equity Plan by reason of any such corporate transaction in substitution for awards previously granted by such corporation or entity to such person (“substitute awards”). The terms and conditions of the substitute awards may vary from the terms and conditions that would otherwise be required by the 2017 Equity Plan solely to the extent the Administrator deems necessary for such purpose. Any such substitute awards will not reduce the share reserve; provided, however, that such treatment is permitted by applicable law and the listing requirements of the Nasdaq or other exchange or securities market on which the Common Stock is listed.

Adjustments or Changes in Capitalization

In the event of any change in the outstanding shares of Common Stock by reason of a recapitalization, reclassification, stock dividend, extraordinary dividend, stock split, reverse stock split or other distribution, merger, reorganization, consolidation, combination, spin-off or other similar corporate change or any other change that affects our Common Stock, the aggregate number of shares of Common Stock available under the 2017 Equity Plan or subject to outstanding awards (including the exercise price of any awards) will be adjusted as the Administrator deems appropriate or equitable.

31

Termination of or Changes to the 2017 Equity Plan

The Board may amend, modify, suspend or terminate the 2017 Equity Plan at any time and in any manner. Unless required by applicable law or a listing agency rule, stockholder approval for any amendment, modification, suspension or termination of the 2017 Equity Plan by the Board is generally not required. Unless previously terminated by the Board, the 2017 Equity Plan will terminate on December 15, 2027. Generally speaking, the Compensation Committee may amend outstanding awards in a manner consistent with the 2017 Equity Plan, subject, however, to the consent of the holder if the amendment materially and adversely affects such holder.

Acceleration of Awards; Possible Early Termination of Awards

Upon a change of control of the Company, unless otherwise provided in an award agreement, the Administrator is authorized, but not obligated, to make adjustments in the terms and conditions of the outstanding awards, including, among others, (i) continuing or assuming such outstanding awards, (ii) substituting such outstanding awards for awards with substantially the same terms, (iii) accelerating the exercisability, vesting and/or payment under such outstanding awards, (iv) upon written notice, provide that any outstanding stock option and stock appreciation right is exercisable during a reasonable period of time immediately prior to the scheduled consummation of the event or such other reasonable period as determined by the Administrator followed by the termination of any unexercised portion of such stock option or stock appreciation right within the relevant period, or (v) cancelling all or any portion of such outstanding awards for fair value (in the form of cash, shares of Common Stock, other property or any combination thereof) as determined in the sole discretion of the Administrator. For this purpose, a “change of control” is defined to include (i) the acquisition by certain persons that results in such persons becoming the beneficial ownership of more than 50% of the voting power of the then outstanding voting securities of the Company, (ii) certain changes in the majority of the Board, (iii) the sale of all or substantially all of the Company’s assets, and (iv) the consummation of certain reorganizations, mergers or consolidations.

Transfer Restrictions

Subject to certain exceptions, awards under the 2017 Equity Plan are not assignable or transferable by the recipient and shall not be subject in any manner to assignment, alienation, pledge, encumbrance or charge.

Forfeiture Events

The Administrator may specify in an award agreement at the time of the award that the participant’s rights, payments and benefits with respect to an award are subject to reduction, cancellation, forfeiture or recoupment upon the occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of an award. Such events may include, without limitation, termination of service for cause (as defined in and determined in accordance with the 2017 Equity Plan), violation of material Company policies, breach of noncompetition, non-solicitation, confidentiality or other restrictive covenants that may apply to the participant or other conduct by the participant that is detrimental to the business or reputation of the Company. Under certain circumstances specified in the 2017 Equity Plan, any gain realized by the participant from the exercise, vesting, payment or other realization of income by the participant in connection with an award must be paid back by the participant to the Company. In addition, under certain circumstances, if a participant receives compensation pursuant to an award under the 2017 Equity Plan (whether a stock option, cash performance award or otherwise) based on financial statements that are subsequently required to be restated in a way that would decrease the value of such compensation, the participant will, to the extent not otherwise prohibited by law, upon the written request of the Company, forfeit and repay to the Company the difference between what the participant received and what the participant should have received based on the accounting restatement.

New Plan Benefits

The specific individuals who will be granted awards under the 2017 Equity Plan and the type and amount of such awards will be determined by the Administrator. The number, value and type of awards to be granted to such individuals under the 2017 Equity Plan in the future is undeterminable. If the Equity Plan Amendment is approved by our stockholders, we expect to grant annual stock awards to At-large Directors under the Director Compensation Policy, as described above.

32

Material U.S. Federal Income Tax Consequences

The following summary briefly describes current U.S. federal income tax consequences of rights under the 2017 Equity Plan. The summary is not a detailed or complete description of all U.S. federal tax laws or regulations that may apply, however, and does not address any local, state or other country laws. Therefore, no one should rely on this summary for individual tax compliance, planning or decisions. Participants in the 2017 Equity Plan are encouraged to consult their own professional tax advisors concerning tax aspects of rights under the 2017 Equity Plan and should be aware that tax laws may change at any time.

Stock Options. A participant to whom an incentive stock option, within the meaning of Section 422 of the Code, is granted generally will not recognize income at the time of grant or exercise of such option (although special alternative minimum tax rules may apply to the participant upon option exercise). No federal income tax deduction will be allowable to the Company upon the grant or exercise of such incentive stock option.

When the participant sells shares of Common Stock acquired through the exercise of an incentive stock option more than one year after the date of transfer of such shares and more than two years after the date of grant of such incentive stock option, the participant will normally recognize a long-term capital gain or loss equal to the difference, if any, between the sale prices of such shares and the option price, for which the Company is not entitled to a federal income tax deduction. If the participant does not hold such shares for this period, the sale will constitute a “disqualifying disposition,” and the participant generally will recognize taxable ordinary income in the year of disposition equal to the excess of the fair market value of the shares on the date of exercise over the exercise price of the stock option (or, if less, the excess of the amount realized on the disposition of the shares over the exercise price of the stock option). Subject to applicable limits of the Code and regulations thereunder, the Company will generally be entitled to a federal income tax deduction in the amount of such ordinary income. The balance of the participant’s gain on a disqualifying disposition, if any, will be taxed as short-term or long-term capital gain, as the case may be.

A participant to whom a nonqualified stock option is granted will not recognize income at the time of grant of such option. When such participant exercises a nonqualified stock option, the participant will recognize ordinary income equal to the excess, if any, of the fair market value as of the date of a nonqualified stock option exercise of the shares of Common Stock that the participant receives, over the option exercise price. The tax basis of such shares will be equal to the exercise price paid plus the amount includable in the participant’s gross income, and the participant’s holding period for such shares will commence on the day after which the participant recognized taxable income in respect of such shares. Subject to applicable limits of the Code and regulations thereunder, the Company will generally be entitled to a federal income tax deduction in respect of the exercise of nonqualified options in an amount equal to the ordinary income recognized by the participant. Any gain or loss recognized upon a subsequent sale or exchange of the Common Stock is treated as capital gain or loss for which the Company is not entitled to a deduction.

33

Stock Appreciation Rights. When a stock appreciation right is granted, there are no income tax consequences for the participant or the Company. When a stock appreciation right is exercised, the participant recognizes compensation equal to the cash and/or the fair market value of the shares received upon exercise. Subject to applicable limits of the Code and regulations thereunder, the Company is entitled to a deduction equal to the compensation recognized by the participant.

Restricted Stock. Unless an election is made by the participant under Section 83(b) of the Code, the grant of an award of restricted stock will have no immediate tax consequences to the participant, and the Company will not be allowed a tax deduction at the time the restricted stock are granted. Generally, upon the lapse of restrictions (as determined by the applicable restricted stock agreement between the participant and the Company), a participant will recognize ordinary income in an amount equal to the fair market value of the shares of Common Stock for which the restrictions lapse, less any amount paid, and the Company will be allowed a corresponding tax deduction at that time, subject to applicable limits of the Code and regulations thereunder. The participant’s tax basis will be equal to the sum of the amount of ordinary income recognized upon the lapse of restrictions and any amount paid for such restricted stock. The participant’s holding period for tax purposes will commence on the date on which the restrictions lapse.

A participant may make an election under Section 83(b) of the Code within 30 days after the date of grant of an award of restricted stock to recognize ordinary income on the date of award based on the fair market value of shares of Common Stock on such date, less any amount the participant paid for such Common Stock, and the Company will be allowed a corresponding tax deduction at that time, subject to applicable limits of the Code and regulations thereunder. A participant making such an election will have a tax basis in the restricted stock equal to the sum of the amount the participant recognizes as ordinary income and any amount paid for such restricted stock, and the participant’s holding period for such restricted stock for tax purposes will commence on the grant date. Any future appreciation in the Common Stock will be taxable to the participant at capital gains rates. However, if the restricted stock award is later forfeited, the participant will not be able to recover the tax previously paid pursuant to the participant’s Section 83(b) election.

With respect to restricted stock upon which restrictions have lapsed, when the participant sells such shares, the participant will recognize capital gain or loss consistent with the treatment of the sale of shares received upon the exercise of non-qualified options.

Restricted Stock Units. A participant to whom a restricted stock unit is granted generally will not recognize income at the time of grant. Upon delivery of shares of Common Stock or cash in respect of an restricted stock unit, a participant will recognize ordinary income in an amount equal to the amount of cash or the fair market value of the shares of common stock for which the restrictions lapse, less any amount paid (although the participant may become subject to employment taxes when the right to receive shares becomes “vested” due to retirement eligibility or otherwise), and the Company will be allowed a corresponding tax deduction at that time, subject to applicable limits of the Code and regulations thereunder. Any gain or loss recognized upon a subsequent sale or exchange of the stock (if settled in stock) is treated as capital gain or loss for which the Company is not entitled to a deduction.

Stock Awards and Cash Performance Awards. With respect to cash performance awards and stock awards paid in cash or shares of Common Stock, participants will generally recognize ordinary income equal to the fair market value of the shares of Common Stock or the amount of cash paid on the date on which delivery of shares or payment in cash is made to the participant and the Company will generally be allowed a corresponding tax deduction at that time, subject to applicable limits of the Code and regulations thereunder.

Tax Obligations. Each participant under the 2017 Equity Plan will be responsible for payment of any taxes or similar charges required by law to be paid or withheld with respect to any award. Any required withholdings must be paid by participants on or prior to the payment or other event that results in taxable income with respect to an award. The award agreement may specify the manner in which the withholding obligation shall be satisfied with respect to the particular type of Award, which may include permitting participants to elect to satisfy the withholding obligation by tendering shares of common stock of the Company to the Company or having the Company withhold a number of shares of common stock having a value equal to the minimum statutory tax or similar charge required to be paid or withheld.

Section 409A of the Code. If an award is treated as “nonqualified deferred compensation” and the award does not comply with or is not exempt from Section 409A of the Code, Section 409A of the Code may impose additional taxes, interest and penalties on recipients of awards under the 2017 Equity Plan. All grants made under the 2017 Equity Plan are designed and intended to either be exempt from or comply with Section 409A of the Code to avoid such additional taxes, interest and penalties. However, in the event that the Administrator determines that the awards are

34

subject to Section 409A of the Code, the Administrator shall have the authority to take such actions and to make such changes to the 2017 Equity Plan or an award agreement as the Administrator deems necessary to comply with such requirements; provided, that no such action shall materially and adversely affect any outstanding award without the consent of the affected participant. Neither the Administrator nor the Company is obligated to ensure that awards comply with Section 409A of the Code or to take any actions to ensure such compliance.

Company Deduction and Section 162(m). The Company generally will be entitled to a tax deduction in connection with the vesting, settlement or exercise of an award under the 2017 Equity Plan in an amount equal to the ordinary income realized by a participant at the time the participant recognizes such income. However, Section 162(m) of the Code places a limit of $1 million on the amount of compensation that we may deduct as a business expense in any year with respect to certain of our executive officers. While the Administrator considers the deductibility of compensation as one factor in determining executive compensation, the Administrator retains the discretion to award and pay compensation that is not deductible as it believes that it is in the best interests of our shareholders to maintain flexibility in our approach to executive compensation and to structure a program that we consider to be the most effective in attracting, motivating and retaining key employees.

PROPOSAL NO. 4 – SELECTION AND RATIFICATION OF THE INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS AND AUDITORS

The Audit Committee and the Board seek stockholder ratification of the appointment of KPMG LLP (“KPMG”) to act as the independent registered public accountants and auditors of our consolidated financial statements for the 2024 fiscal year. If the stockholders do not ratify the appointment of KPMG, the Audit Committee will reconsider this appointment.

On March 20, 2024, the Audit Committee of the Board appointed KPMG LLP (“KPMG”) as the Company’s independent registered public accounting firm for the Company’s fiscal year ending December 31, 2024, and on the same day voted to approve the dismissal of Grant Thornton LLP (“Grant Thornton”) as its independent registered public accounting firm. Grant Thornton served as the Company’s independent registered public accounting firm since 2018.

Grant Thornton’s audit reports on the Company’s consolidated financial statements for the fiscal years ended December 31, 2023 and 2022 did not contain an adverse opinion or a disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope or accounting principles, except that each report on the Company’s consolidated financial statements contained an explanatory paragraph regarding the Company’s ability to continue as a going concern based on the Company’s recurring losses from operations and negative cash flows from operating activities as of December 31, 2023 and 2022.

During the Company’s two most recent fiscal years ended December 31, 2023 and 2022, and during the subsequent interim period through March 20, 2024, there were (i) no disagreements within the meaning of Item 304(a)(1)(iv) of Regulation S-K with Grant Thornton on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures, which, if not resolved to Grant Thornton’s satisfaction, would have caused Grant Thornton to make reference to the subject matter of the disagreements in its reports on the Company’s consolidated financial statements for such years, and (ii) no “reportable events” as defined in Item 304(a)(1)(v) of Regulation S-K.

During the Company’s two most recent fiscal years ended December 31, 2023 and 2022, and during the subsequent interim period through March 20, 2024, neither the Company nor anyone acting on its behalf has consulted with KPMG, regarding either: (i) the application of accounting principles to a specific transaction, completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements, and neither a written report nor oral advice was provided to the Company that KPMG concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing, or financial reporting issue, or (ii) any matter that was either the subject of a “disagreement” (as defined in Item 304(a)(1)(iv) of Regulation S-K) or a “reportable event” (as described in Item 304(a)(1)(v) of Regulation S-K).

Representatives of KPMG and Grant Thornton are expected to be present at the Annual Meeting to respond to appropriate questions, and those representatives will also have an opportunity to make a statement if they desire to do so.

Vote Required for Approval

The affirmative vote of a majority in voting power of the Common Stock present in person or by proxy at the Annual Meeting and entitled to vote on Proposal 4 is required to ratify the selection of the independent auditors.

The Board unanimously recommends that the stockholders vote “FOR” the ratification of the appointment of KPMG as the Company’s independent registered public accountants and auditors for fiscal year 2024.

CERTAIN RELATIONSHIPS AND RELATED PERSON TRANSACTIONS

The Board adopted a written Related Person Transaction Policy in October 2017, which addresses the reporting, review and approval or ratification of transactions with related persons. Although related person transactions can involve potential or actual conflicts of interest, the Company recognizes that such transactions may occur in the normal course of business or provide an opportunity that is in the best interests of the Company. The Related Person Transaction Policy is not designed to prohibit related person transactions; rather, it is to provide for timely internal review of prospective transactions, approval or ratification of transactions and appropriate oversight and public disclosure of transactions.

Pursuant to the Related Person Transaction Policy, any transaction or arrangement or series of transactions or arrangements between the Company, any subsidiary of the Company or any other company controlled by the Company participates, whether or not the Company is a party, and a “related person” in which such person will have a material direct or indirect interest must be submitted to the disinterested members of the Board for review, approval or ratification. A “related person” means any director, director nominee or executive officer of the Company, any holder of more than 5% of the outstanding voting securities of the Company, or any immediate family member of the foregoing persons.

The disinterested members of the Board will consider all relevant factors when determining whether to approve or ratify a related person transaction, including whether such transaction is in, or not inconsistent with, the best interests of the Company, and whether such transaction is comparable to a transaction that could be available on an arms-length basis or is on terms that the Company offers generally to persons who are not related persons and whether such transaction. Specific types of transactions are excluded from the Related Person Transaction Policy, such as, for example, transactions in which the related person’s interest arises solely from his or her service as a director of, or direct or indirect ownership of less than a ten percent (10%) equity interest in, another entity that is a party to the transaction.

In addition to the Related Person Transaction Policy, the Code of Conduct requires that conflicts of interests involving persons other than directors, director nominees and executive officers must be approved by the Operations Committee.

The following is a discussion of transactions since January 1, 2022 between the Company and its directors, director nominees, executive officers, any holder of more than 5% of any class of the Company’s voting securities, or any immediate family member of the foregoing persons:

Series C Preferred Stock Offerings

In February 2022, the Company entered into a Series C Preferred Stock Purchase Agreement with TEP Next Decade, LLC ("TEP NextDecade"), pursuant to which the Company sold an aggregate of 5,000 shares of Series C Preferred Stock at $1,000.00 per share for an aggregate purchase price of $5.0 million, issued Series C Warrants and issued an additional 100 shares of Series C Preferred Stock in aggregate as origination fees to TEP Next Decade.

In addition, the Audit Committee has discussed with the Company’s independent auditors the matters required to be discussed under applicable Public Company Accounting Oversight Board (the “PCAOB”) rules. The Audit Committee has received the written disclosures and the letter from the independent auditors required by the PCAOB regarding the independent auditor’s communication with the Audit Committee concerning independence, has discussed with the independent auditor all relationships between the auditors and the Company that may bear on the auditor’s independence and any relationships that may impact their objectivity and independence and has satisfied itself as to the auditor’s independence.

Based on the Audit Committee’s discussions with management and the independent auditors, the Audit Committee’s review of the audited financial statements as of and for the year ended December 31, 2023, representations of management and the report of the independent auditors, the Audit Committee recommended to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023.
