 A more complete description of the Audit Committee's functions is set forth in the Audit Committee's charter which is published on the "Investor Relations" section of the Company's website at www.plugpower.com. Our website is not incorporated into or a part of this Amendment No. 1.

 In accordance with the Audit Committee's charter, management has the primary responsibility for the financial statements and the financial reporting process, including maintaining an adequate system of internal controls over financial reporting. The Company's independent registered public accounting firm reports directly to the Audit Committee and is responsible for performing an integrated audit of the Company's consolidated financial statements and internal control over financial reporting, in accordance with the standards of the Public Company Accounting Oversight Board (United States). The Audit Committee, among other matters, is responsible for appointing the Company's independent registered public accounting firm, (i) evaluating such independent registered public accounting firm's qualifications, independence and performance, (iii) determining the compensation for such independent registered public accounting firm, and (iv) pre-approving all audit and non-audit services.
 Code of Conduct
 We have adopted the Code of Business Conduct and Ethics (the "Code of Conduct"), which is applicable to all of our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. Our Code of Conduct is a "code of ethics" as defined in Item 406(b) of Regulation S-K and embodies our principles and practices relating to the ethical conduct of our business and our long-standing commitment to honesty, fair dealing and full compliance with all laws affecting our business. In the event that we amend or waive certain provisions of our Code of Conduct in a manner that requires disclosure under applicable rules, we intend to provide such required disclosure on our website in accordance with applicable SEC and Nasdaq Rules. Our Code of Conduct is available on our website at www.plugpower.com under the Investor Relations section. Our website is not incorporated into or a part of this Amendment No. 1.
 Corporate Governance Guidelines
 We have adopted corporate governance guidelines that serve as a flexible framework within which our Board of Directors and its committees operate. These guidelines cover a number of areas including Board membership criteria and director qualifications, director responsibilities, Board structure, Board member access to management and independent advisors, director compensation, director orientation and continuing education, evaluation of senior management and management succession planning. A copy of our corporate governance guidelines is published on our website at www.plugpower.com under the Investor Relations section. Our website is not incorporated into or a part of this Form 10-K.
 Insider Trading Policy
 We have adopted an insider trading policy (the "Insider Trading Policy") governing the purchase, sale and other dispositions of the Company's securities that applies to all of the Company's directors, officers, employees and other covered persons. Among other things, the policy prohibits any director, officer, employee or other covered person of the Company from (i) engaging in short sales of the Company's securities and from trading in puts, calls or options in respect of the Company's securities; (ii) buying or selling puts, calls or other derivative securities of the Company or engaging in any other hedging transactions with respect to the Company's securities; (iii) purchasing any securities of the Company with money borrowed from a bank, brokerage firm or other person for the purpose of purchasing securities or using the Company's securities as collateral in a margin account; (iv) pledging Company securities as collateral for a loan (or modifying an existing pledge); or (v) donating or making any other transfer of Company securities without consideration when the donating employee, director, or executive officer is not permitted to trade, unless the donee agrees not to sell the shares until the donating employee, director, or executive officer is permitted to sell. We believe that our Insider Trading Policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and listing standards applicable to the Company. It is also the policy of the Company to comply with all insider trading laws and regulations with regard to the Company's trading in its own securities. A copy of the Insider Trading Policy can found as Exhibit 19.1 to the Original Form 10-K.
 Equity Grant Timing
 During 2024, our Board and Compensation Committee did not take into account any material non-public information when determining the timing and terms of equity incentive awards, and we did not time the disclosure of material non-public information for the purpose of affecting the value of executive compensation. During 2024, we did not grant stock options to any of our named executive officers during any period beginning four business days before and ending one business day after the filing or furnishing of a Form 10-K, 10-Q or 8-K that discloses material non-public information.

 Delinquent Section 16(a) Reports
 Section 16(a) of the Exchange Act requires the Company's officers, as defined by Section 16, directors, and persons or entities who own more than 10% of a registered class of the Company's equity securities, to file initial reports of ownership and reports of changes in ownership with the SEC. Such persons or entities are required by SEC regulations to furnish the Company with copies of all Section 16(a) forms they file. To our knowledge, based on our review of the copies of such filings and based on written representations, we believe that all such persons and entities complied on a timely basis with all Section 16(a) filing requirements during the fiscal year ended December 31, 2024, except that the following persons filed the following Form 4s late on the following dates:

 On April 8, 2024, Kavita Mahtani filed a Form 4 disclosing an award of common stock made on April 1, 2024 pursuant to the Company's Non-Employee Directors Compensation Plan.

 On August 9, 2024, Paul B. Middleton, Gerard L. Conway, Jr., and Jose Luis Crespo each filed a Form 4 disclosing a tax withholding event in connection with the vesting of restricted stock awards on May 9, 2024.

 The following discussion should be read together with the compensation tables and related disclosures that follow.
 Executive Summary
 2024 Say on Pay and Investor Feedback
 Every year we invite our stockholders to cast an advisory vote to approve the compensation of our named executive officers. At our 2024 annual meeting of stockholders, we received the support of approximately 78.3% of the votes cast for our "say-on-pay" advisory vote. We value the views of our stockholders and intend to maintain a compensation framework that reflects our pay-for-performance compensation philosophy, is aligned with the long-term interests of our stockholders and in line with sound governance practices.
 As of April 2025, our stockholder base is represented by approximately 49.66% retail investors and approximately 50.34% institutional investors. During 2024, we reached out to 150 of our largest institutional investors representing approximately 81.69% of our institutional common stock ownership. Four institutional investors representing approximately 34.47% of our institutional common stock ownership accepted our invitation and we met with each of them.
 We pay careful attention to any feedback we receive from our stockholders about our executive compensation program. There were two themes that emerged from our shareholder outreach:

 First, while stockholders generally commended our rigorous adherence to a pay-for-performance philosophy, some expressed concern about the retentive power of underwater equity awards and the motivational power of a bonus program that has resulted in zero bonus payouts in consecutive years. These concerns were acknowledged by the Board and several 2024 and 2025 pay actions, as described more fully in this Compensation Discussion and Analysis, are responsive to the retention risk the Company faces, including retention awards and special bonuses granted in 2024 and the waiver of the stock price hurdle for certain stock options awarded in 2024.

 Certain investors also expressed interest in seeing our Chief Executive Officer invest directly in the Company. Our Chief Executive Officer, Mr. Marsh, has irrevocably elected to have 50% of his 2025 base salary and annual cash bonus paid in shares of the Company's common stock.

 Executive Compensation Program
 Our goal is to retain and attract experienced and talented executive officers and to motivate them to achieve our short-term and long-term financial, operational and strategic objectives that produce and promote stockholder value. To achieve this goal, we strongly emphasize a culture of pay-for-performance to provide incentives and accountability for our executive officers in working toward the achievement of our objectives. Accordingly, we have designed our incentive compensation programs with the goal of ensuring that actual pay varies above or below targeted compensation opportunity based on achievement of challenging performance goals and demonstration of meaningful individual commitment and contribution.

 Key elements of our compensation programs include the following:

 Compensation Element

 Purpose

 Features

 Base salary

 To attract and retain experienced and highly skilled executives.

 Fixed component of pay to provide financial stability, based on responsibilities, experience, individual contributions and competitive market data. Following a period of no base salary increases since 2021, the incumbent named executive officers' base salaries were adjusted to reflect current competitive market levels.

 Annual cash bonus

 To promote and reward the achievement of key short-term strategic and business goals of the Company; to motivate and attract executives.

 Variable component of pay based on annual business and operating quantitative and qualitative goals. We set rigorous goals and the 2024 bonus was earned 0% for all named executive officers other than Messrs. Middleton and Fullerton, whose 2024 target bonuses were guaranteed in connection with their respective new employment arrangements.

 Long-term equity incentive compensation

 To encourage executives and other employees to focus on long-term Company performance; to drive long-term stockholder value; to promote retention; to reward outstanding Company and individual performance.

 Subject to multi-year vesting based on performance goals and/or continued service. For 2024, the named executive officers received annual long-term equity awards entirely in the form of stock options: 50% of the award consisted of performance-based stock options ("PSOs") with a rigorous price-vesting hurdle and the remaining 50% consisted of time-based stock options. As of December 31, 2024, no portion of the PSOs had been earned as the stock price hurdle of $7.50 per share had not been achieved by April 30, 2025. However, in light of market conditions and other factors impacting the Company's stock price performance and to incentivize retention, on April 21, 2025, the Compensation Committee waived the stock price hurdle for the PSOs issued to Messrs. Marsh, Fullerton and Conway such that 100% of the PSOs held by them are now subject only to time-based vesting requirements.

 Relocation Payment

 To reduce an executive's personal financial burden in connection with a relocation at the Company's request.

 Mr. Shrestha received a relocation payment of $575,000 that he would have been required to repay in full if he failed to relocate to within 30 miles of Latham, New York by December 31, 2024. Mr. Shrestha completed the relocation before December 31, 2024.

 Retention Awards

 To retain key executives during a critical period. Note: Our CEO, Mr. Marsh, did not participate in the retention award program.

 Messrs. Middleton and Conway each received a retention award with a total value of $440,000. The retention award was paid 25% in cash and 75% in the form of restricted stock, vesting in equal installments over a 1-year service period. The restricted stock portion of the retention awards was issued on May 9, 2024 and each of Messrs. Middleton and Conway received 119,134 restricted shares of common stock that vest 25% upon grant, 25% 90 days after grant, 25% 180 days after grant, and 25% 360 days after grant. Mr. Shrestha received a $100,000 special bonus on April 26, 2024 as recognition for his past contributions to the Company. In connection with Mr. Shrestha's relocation commitment (see above) and in recognition of the long-term commitment to Plug that was expected of him, Mr. Shrestha received a $575,000 cash retention award on May 10, 2024, which is subject to full or partial clawback if Mr. Shrestha either voluntarily terminates employment without good reason or is involuntarily terminated for cause before May 10, 2028.

 Special Awards Pursuant to New Employment Agreements

 To address specific talent recruitment needs as they arise.

 Mr. Fullerton received a $275,000 signing bonus to accept our employment offer. Mr. Middleton received a restricted stock award with a value of approximately $2.5 million to induce him to enter into a new employment agreement and remain in the employ of the Company. The award vests in equal annual installments over a three-year period.

 Executive Compensation Practices
 The Compensation Committee reviews on an ongoing basis the Company's executive compensation program to evaluate whether it supports the Company's executive compensation objectives and is aligned with stockholder interests. Our executive compensation practices include the following, each of which the Compensation Committee believes reinforces our executive compensation objectives:
 What We Do

 What We Don't Do

 Pay-for-performance by structuring a significant percentage of target annual compensation in the form of variable, at-risk compensation

 Allow hedging or pledging of equity

 Offer market-competitive benefits for executives that are consistent with the rest of our employees

 Allow for re-pricing of stock options without stockholder approval

 Consult with an independent compensation consultant on compensation levels and practices

 Provide excessive perquisites

 Maintain robust stock ownership guidelines

 Provide supplemental executive retirement plans

 Have a clawback policy that applies to cash and equity incentive compensation

 Provide any excise tax gross-ups

 Hold an annual say-on-pay vote

 Provide single-trigger severance arrangements

 Setting Executive Compensation
 The Compensation Committee is responsible for reviewing, and recommending to the Board for approval, the compensation of our executive officers, including our named executive officers. The Compensation Committee is composed entirely of non-employee directors who are "independent" as that term is defined in the applicable Nasdaq Rules. In making its recommendations regarding executive compensation, our Compensation Committee annually reviews the performance of our executives with our Chief Executive Officer, and our Chief Executive Officer makes recommendations to our Compensation Committee with respect to the appropriate base salary, annual incentive bonuses and performance measures, and grants of long-term equity incentive awards for each of our executives (other than himself). The Chairman of the Compensation Committee makes recommendations to the Compensation Committee with respect to the Chief Executive Officer's compensation.
 In setting executive base salaries and annual cash bonuses and granting equity incentive awards, the Compensation Committee and the Board consider compensation for comparable positions in the market, the historical compensation levels of our executives, individual performance as compared to our expectations and objectives, and our desire to motivate our executives to achieve short and long-term results that are in the best interests of our stockholders.
 Independent Compensation Consultant
 For purposes of evaluating 2024 compensation for each of our named executive officers, our Compensation Committee retained FW Cook as its independent compensation consultant. FW Cook has not performed services for the Company other than consulting services related to the compensation and benefits of our executives and non-employee directors. FW Cook assisted the Compensation Committee in the development of comparator groups and provided their market analysis of the various components of compensation for the named executive officer positions, including base salary, annual cash bonus and equity compensation. Our Compensation Committee has analyzed whether the work of FW Cook raised any conflict of interest, taking into account relevant factors in accordance with SEC guidelines and Nasdaq Rules. Based on its analysis, our Compensation Committee determined that the engagement of FW Cook does not create any conflict of interest pursuant to the SEC guidelines and Nasdaq Rules.

 Comparator Group Selection and Market Data
 We operate in a highly specialized niche industry — the core of our business is the hydrogen molecule and, as a hydrogen supply chain company, we must attract and retain manufacturing and service technicians, engineers, scientists, innovators, and business leaders who have the passion and expertise to run our business.
 Developing a peer group for the Company for compensation comparison purposes is challenging because there are few pure green hydrogen peer companies that are publicly-traded, stand-alone, U.S.-based, and size-appropriate. Furthermore, due to the nature of our business, we also compete for executive talent with companies outside our peer group, including public companies that are larger and more established than we are or that possess greater resources than we do, and with smaller private companies that may be able to offer greater compensation potential. Our talent competitors run the spectrum from market leading alternative technology companies, to deep pocketed legacy fossil fuel companies who are now embracing hydrogen, to the next generation of ambitious startups with the potential to be green unicorns who can offer lucrative incentive compensation packages.
 In light of the foregoing, the Compensation Committee recognizes that it is not possible to create a "perfect" peer group for Plug Power and determined to minimize the substantial investment of time and resources required for developing a traditional compensation peer group. Instead, the Compensation Committee attempted to obtain a general sense of competitive market pay by assessing compensation levels within the following limited sample set of renewable energy companies:

 Bloom Energy (BE)

 First Solar (FSLR)

 SunPower (SPWR)

 Chart Industries (GTLS)

 FuelCell Energy (FCEL)

 Sunrun (RUN)

 Enphase Energy (ENPH)

 SolarEdge Tech. (SEDG)

 Wolfspeed (WOLF)

 The Compensation Committee considered each executive's level and job performance, their duties and responsibilities at the Company compared to the duties and responsibilities of executive officers in similar positions at the comparator group companies, and other circumstances unique to the Company, and evaluated whether the compensation elements and levels provided to our executives were generally appropriate relative to their responsibilities at the Company and compensation elements and levels provided to their counterparts in the comparator group or within survey data.
 The Compensation Committee considered both objective and subjective criteria to evaluate Company and individual performance and the competitive landscape, which allowed it to exercise informed judgment and not rely solely on rigid benchmarks. Accordingly, the Compensation Committee did not formulaically tie compensation decisions to any particular percentile level of total compensation paid to executives at a comparator group or survey data.
 Our Executive Compensation Program
 Each of the primary elements of our executive compensation is discussed in detail below and the compensation paid to our named executive officers with respect to 2024 is discussed under each element. In the descriptions below, we have identified particular compensation objectives that we have designed our executive compensation programs to serve; however, we have designed our compensation programs to complement each other and to collectively serve all of our executive compensation objectives described above. Accordingly, whether or not specifically mentioned below, we believe that, as a part of our overall executive compensation, each element to a greater or lesser extent serves each of our objectives.
 2024 Base Salary
 Base salaries have historically represented the smallest component of each named executive officer's total direct compensation opportunity and represent a fixed amount paid to each executive for performing his normal duties and responsibilities. Our executives' base salaries reflect the initial base salaries that we negotiated with each of our executives at the time of his initial employment or promotion and subsequent adjustments to these amounts to reflect market and merit increases, the growth and stage of development of our Company, our executives' performance and increased experience, changes in our executives' roles and responsibilities, and other factors.

 The following table sets forth the annual base salaries for our named executive officers for each of 2023 and 2024, as well as the percentage increase year-over-year. For the incumbent named executive officers, base salaries were increased for the first time since 2021.

 Mr. Shrestha's base salary was initially increased to $440,000 (effective as of May 9, 2024) and subsequently increased to $500,000 (effective as of November 7, 2024) in connection with his promotion to President.

 (3)
 Mr. Middleton's base salary was initially increased to $440,000 (effective as of May 9, 2024) and subsequently increased to $600,000 (effective as of November 19, 2024) in connection with entering into a new employment agreement.

 2024 Annual Cash Bonuses
 Annual bonuses for 2024 were based upon Company performance as measured against pre-established performance goals, including financial measures and achievement of strategic objectives. The primary objective of the annual bonus program is to motivate and reward our executive officers for meeting financial, operational and strategic performance goals that drive the long-term success of our business.
 The Compensation Committee determined the 2024 annual cash bonus awards for the named executive officers using the following framework:

 For 2024, the target bonus opportunity for each named executive officer was 100% of base salary, the threshold was 50% of base salary, and the maximum for stretch performance was 150% of base salary.
 For 2024, the Compensation Committee selected the following metrics for the annual bonus plan: Gross Margin, Cash Usage, Revenue, Bookings, Inventory, and Plan Construction and Investment. Cash Usage is defined as the change in unrestricted cash less any cash proceeds from equity offerings of the Company. Inventory is defined as the ending inventory balance at December 31, 2024, plus inventory write-downs during 2024. The Compensation Committee selected these metrics to provide a clear link between the annual bonus opportunity and underlying financial and operating performance. As the metrics are intended to focus on the fundamentals of annual business performance, adjustments are made for items that are not indicative of core performance. The purpose of these adjustments is to ensure that the measurement of performance reflects factors that management can directly control and that payout levels are not artificially inflated or impaired by factors unrelated to the core operation of the business. Accordingly, the calculation of one or more of these metrics for compensatory purposes may differ from the calculation for external financial reporting purposes.

 The 2024 Company goals established by the Compensation Committee for each metric, the relative weightings assigned to each metric, and the actual performance against these goals for 2024 are set forth below. In comparison to 2023, (i) a target range was used for several metrics to address challenges associated with setting performance goals with precision and to avoid unintended windfalls and shortfalls in actual payouts, and (ii) the stretch payout opportunity was reduced from 200% to 150% of target.

 2024 Long-Term Equity Incentive Compensation
 In 2024, we granted annual long-term equity incentive awards to the named executive officers in the form of PSOs (weighted 50%) and time-based stock options (weighted 50%) to achieve the following three core objectives:
 Incentivize and retain Plug's senior leadership team;
 Adhere to Plug's pay-for-performance compensation philosophy; and
 Align with Plug's stockholders' interests.
 The stock options have an exercise price per share equal to the closing price of the common stock on the date of grant. At the time of grant, the PSOs were only eligible to be earned and vest if a stock price hurdle of $7.50 (based on the daily volume weighted average price of the Company's common stock during any 30 consecutive trading day period during the performance period) was achieved on or before April 30, 2025. As described below, on April 21, 2025, the Committee determined to waive the stock price hurdle

 for the PSOs issued to Messrs. Marsh, Fullerton and Conway such that 100% of the PSOs held by them are now subject only to time-based vesting requirements. The time-based stock options and the PSOs (to the extent earned) vest in three equal annual installments following the grant date. All stock options granted in 2024 were underwater as of April 30, 2025.
 The number of shares underlying the stock option awards granted to each named executive officer in 2024 is set forth below:

 Stock options granted to named executive officers other than Mr. Fullerton were granted on April 26, 2024 and have an exercise price of $2.41, the closing price of the Company's common stock on the Nasdaq Capital Market on April 26, 2024.

 (2)
 Mr. Fullerton's options were granted in connection with his hire and have an exercise price of $2.47, the closing price of the Company's common stock on the Nasdaq Capital Market on July 31, 2024.

 As of December 31, 2024, the PSOs had not been earned and on April 21, 2025, in light of market conditions and other factors impacting the Company's stock price performance and to incentivize retention, the Compensation Committee waived the performance-based vesting requirements for the PSOs issued to Messrs. Marsh, Fullerton and Conway so that the PSOs issued to them remain subject to only time-based vesting requirements. There were no changes to the exercise price of the PSOs. The PSOs granted to Messrs. Shrestha and Middleton were not earned and were forfeited in their entirety.
 Retention Awards for Messrs. Middleton and Conway
 On May 9, 2024, the Compensation Committee approved retention awards for certain key employees, including certain of the Company's named executive officers, to enable the Company to retain and motivate such key employees during a critical period. Messrs. Middleton and Conway each received a retention award with a total value of $440,000. The retention awards were paid 25% in cash and 75% in the form of restricted stock. The restricted stock portion of the retention awards was issued on May 9, 2024 and each of Messrs. Middleton and Conway received 119,134 restricted shares of common stock. The retention restricted stock award was subject to the following vesting schedule: 25% upon grant, 25% 90 days after grant, 25% 180 days after grant, and 25% 360 days after grant.
 Special Awards for Mr. Shrestha
 On April 26, 2024, Mr. Shrestha received a $100,000 special bonus as recognition for his past contributions to the Company.
 On May 9, 2024, the Compensation Committee approved a relocation and retention award for Mr. Shrestha pursuant to a relocation and retention agreement with the Company (the "Relocation and Retention Agreement"). Pursuant to the Relocation and Retention Agreement, (i) in consideration of Mr. Shrestha's relocation of his primary residence to within 30 miles of the Company's headquarters in Latham, New York no later than December 31, 2024, the Company paid Mr. Shrestha a one-time, contingent relocation payment of $575,000 that he would have been required to repay in full if he failed to relocate to within 30 miles of Latham, New York by December 31, 2024; and (ii) in order to promote Mr. Shrestha's continued employment and dedication to the Company, Mr. Shrestha received a retention payment of $575,000 (the "Retention Payment") that is subject to repayment in full or in part if Mr. Shrestha either

 voluntarily terminates employment without good reason or is involuntarily terminated for cause before May 10, 2028 as set forth in the table below:

 Special Awards Pursuant to New Employment Agreements
 In connection with Mr. Fullerton's acceptance of our offer to serve as the Company's Chief Operating Officer, Mr. Fullerton received a one-time signing bonus of $275,000, which is subject to repayment in full or part if he resigns from his position, or his employment is terminated for cause or for a reason other than reduction in force before the second anniversary of his start date. If he is employed with the Company for one (1) year or less, he is required to repay the full amount of the signing bonus. If he is employed with the Company for more than one (1) year but less than two (2) years, he is required to repay a prorated portion of the signing bonus.
 In connection with Mr. Middleton's entry into a new employment agreement and agreement to continue to serve as the Company's Chief Financial Officer, Mr. Middleton received a retention award of 1,302,084 restricted shares of common stock, which vests in three equal annual installments on the first, second and third anniversaries of the grant date.
 Additionally, Messrs. Fullerton and Middleton's 2024 target bonuses were guaranteed pursuant to their respective employment agreements.
 Employment Arrangements
 The named executive officers are party to employment agreements with the Company that provide for severance benefits upon certain qualifying terminations of employment with the Company. The Compensation Committee considers these severance benefits to be an important part of the executive compensation program and consistent with competitive market practice. Consistent with market practices, the employment agreements do not include change in control-related tax gross-ups. In addition, the award agreements for the stock options granted in 2024 provide for potential accelerated vesting in connection with a change in control transaction. Additional information regarding the employment arrangements with each of our named executive officers, including a quantification of benefits that would have been received by each named executive officer had his employment terminated on December 31, 2024, is provided under "Employment Arrangements" and "Potential Payments upon Termination or Change in Control" below.
 Broad-Based Benefits
 All full-time employees, including our named executive officers, are eligible to participate in our health and welfare benefit programs, including medical, dental, and vision care coverage, disability insurance and life insurance, and our 401(k) plan on the same basis as other employees.
 Currently, we do not view perquisites or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not provide perquisites to our named executive officers, except in situations where we believe it is appropriate to assist an individual in the performance of their duties, to make them more efficient and effective, and for recruitment and retention purposes.
 Relationship of Executive Compensation to Risk
 The Compensation Committee considers whether the design of the Company's executive compensation program encourages senior executives to engage in excessive risk-taking. The Compensation Committee reviews the overall program design, as well as the balance between short-term and long-term compensation, the metrics used to measure performance and the award opportunity under the Company's incentive compensation program, and the implementation of other administrative features designed to mitigate risk such as vesting requirements, stock ownership guidelines and our clawback policy, each as described in this Compensation Discussion and Analysis. Based on its review, the Compensation Committee believes that the Company's executive compensation program is aligned to the interests of stockholders, appropriately rewards pay for performance, and does not promote unnecessary or excessive risk.

 Stock Ownership Guidelines
 The Company believes it is important for directors and officers to hold Company stock. To that end, the Board has adopted stock ownership guidelines for directors and officers and these guidelines are also considered when granting long-term equity incentive awards to executives. The ownership guidelines provide a target level of Company equity holdings with which directors and officers are expected to comply by the earlier of the five-year anniversary of the date of his or her appointment as a director or officer and the five-year anniversary of the effective date of the stock ownership guidelines. The target stock holdings are determined as a multiple of the director or officer's base director's fee or base salary, as applicable, as follows: 5x for all directors and the Chief Executive Officer, 3x for the other named executive officers, and 1x for other Section 16 officers and other vice presidents/officers, and then converted to a fixed number of shares using a 200-day average stock price. The following shares are included in determining compliance with the stock ownership guidelines: (i) shares owned outright by the director or officer or his or her immediate family members residing in the same household; (ii) shares held in the Plug Power Inc. Savings and Retirement Plan; (iii) shares purchased pursuant to the Plug Power Inc. Employee Stock Purchase Plan; (iv) restricted stock issued as part of an executive's annual or other bonus (whether or not vested); (v) shares acquired upon the exercise of employee stock options; (vi) shares held in trust; and (vii) in the case of a director, shares held by a corporation controlled by that director. As of December 31, 2024, all non-employee directors who have served on the Board for at least five years and officers subject to the stock ownership guidelines, other than Mr. Shrestha, were in compliance with the stock ownership requirements.
 Prohibition Against Hedging and Pledging
 The Company's Insider Trading Policy, among other things, prohibits any director, officer, employee or other covered person of the Company from (i) engaging in short sales of the Company's securities and from trading in puts, calls or options in respect of the Company's securities; (ii) buying or selling puts, calls or other derivative securities of the Company or engaging in any other hedging transactions with respect to the Company's securities; (iii) purchasing any securities of the Company with money borrowed from a bank, brokerage firm or other person for the purpose of purchasing securities or using the Company's securities as collateral in a margin account; (iv) pledging Company securities as collateral for a loan (or modifying an existing pledge); or (v) donating or making any other transfer of Company securities without consideration when the donating employee, director, or executive officer is not permitted to trade, unless the donee agrees not to sell the shares until the donating employee, director, or executive officer is permitted to sell.
 Clawback Policy
 On November 30, 2023, the Company adopted an updated Compensation Recovery Policy, effective as of October 2, 2023 (the "Clawback Policy"), to comply with applicable Nasdaq Rules. The Clawback Policy provides that if the Company is required to prepare an accounting restatement due to its material non-compliance with any financial reporting requirement, the Company must reasonably promptly recover (subject to certain limited exceptions described in the Clawback Policy and as permitted by the final clawback rules) any cash or equity incentive compensation received by any current or former executive officer during the three fiscal years preceding the date the Company is required to restate its financial statements that is in excess of the amount that would have been received based on the restated financial statements. The recovery of such compensation applies regardless of whether a covered executive engaged in misconduct or otherwise caused or contributed to the requirement to prepare an accounting restatement. The foregoing summary of the Clawback Policy does not purport to be complete and is qualified in its entirety by reference to the full text of the Clawback Policy, a copy of which can be found as Exhibit 97 to the Original Form 10-K.
 Tax and Accounting Considerations
 Deductibility of Executive Compensation
 The Compensation Committee considered the deductibility of compensation for federal income tax purposes in the design of the Company's compensation programs. While the Company generally seeks to maintain the deductibility of the incentive compensation paid to its executive officers, the Compensation Committee retains the flexibility necessary to provide cash and equity compensation in line with competitive practices, its compensation philosophy and the best interests of stockholders, even if these amounts are not fully tax deductible.

 Taxation of "Parachute" Payments
 Sections 280G and 4999 of the Internal Revenue Code of 1986, as amended (the "Code"), provide that executive officers and directors who hold significant equity interests and certain other service providers may be subject to significant additional taxes if they receive payments or benefits in connection with a change in control of the Company that exceed certain prescribed limits, and that the Company (or a successor) may forfeit a deduction on the amounts subject to this additional tax. We have not agreed to provide any executive officer, including any named executive officer, or director with a "gross-up" or other reimbursement payment for any tax liability that the executive officer or director might owe as a result of the application of Sections 280G or 4999 of the Code.
 Section 409A of the Internal Revenue Code
 Section 409A of the Code imposes additional significant taxes in the event that an executive officer, director or service provider receives "deferred compensation" that does not satisfy the requirements of Section 409A of the Code. Although we do not currently maintain a nonqualified deferred compensation plan, Section 409A of the Code may apply to certain severance arrangements, bonus arrangements and equity awards. We aim to structure all our severance arrangements, bonus arrangements and equity awards in a manner to either avoid the application of Section 409A or, to the extent doing so is not possible, to comply with the applicable requirements of Section 409A of the Code.
 Accounting for Stock-Based Compensation
 We follow Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 718 for our stock-based compensation awards. FASB ASC Topic 718 requires us to measure the compensation expense for all share-based awards made to our employees and non-employee members of our Board, including options to purchase shares of our common stock and other stock awards, based on the grant date "fair value" of these awards. This calculation is performed for accounting purposes and reported in the executive and director compensation tables required by the federal securities laws, even though the recipient of the awards may never realize any value from their awards.
 Compensation Committee Report
 The following report of the Compensation Committee of the Board of Directors will not be deemed incorporated by reference by any general statement incorporating by reference this Amendment No. 1 into any of the Company's filings under the Securities Act or the Exchange Act, except to the extent that the Company specifically incorporates this information by reference, and will not otherwise be deemed filed under such Acts.
 The Compensation Committee reviews and evaluates individual named executive officers and recommends or determines the compensation for each named executive officer. The Compensation Committee also oversees management's decisions concerning the performance and compensation of other Company officers, administers the Company's incentive compensation and other stock-based plans, evaluates the effectiveness of its overall compensation programs, including oversight of the Company's benefit, perquisite and employee equity programs, and reviews the Company's management succession plans. A more complete description of the Compensation Committee's functions is set forth in the Compensation Committee's charter which is published on the "Investor Relations" section of the Company's website at www.plugpower.com. Each member of the Compensation Committee is an independent director as defined in the Nasdaq Rules.
 The Compensation Committee has reviewed the "Compensation Discussion and Analysis" and discussed it with management. Based on its review and discussions with management, the Compensation Committee recommended to our Board of Directors that the "Compensation Discussion and Analysis" be included in the Company's Annual Report on Form 10-K/A for the fiscal year ended December 31, 2024 and the Company's proxy statement relating to the Company's 2025 Annual Meeting of Stockholders. This report on executive compensation is provided by the undersigned members of the Compensation Committee of the Board of Directors.

 Pay Ratio Disclosure
 Pursuant to a mandate of the Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act"), the SEC adopted a rule requiring annual disclosure of the ratio of the median employee's annual total compensation to the total annual compensation of the principal executive officer ("PEO"). The PEO of our Company is Mr. Marsh.
 We identified the median employee using our employee population on December 31, 2024 (including all employees, whether employed on a full-time, part-time, seasonal or temporary basis). We identified the median employee using the amount reported as compensation on the employee's Form W-2 for the year ended December 31, 2024 for all individuals who were employed by us on December 31, 2024, the last day of our payroll year (whether employed on a full-time, part-time, or seasonal basis). Our median employee compensation for the year ended December 31, 2024 as calculated using Summary Compensation Table requirements was $66,793. Mr. Marsh's compensation for the year ended December 31, 2024 as reported in the Summary Compensation Table was $2,240,079. Therefore, our Chief Executive Officer pay ratio is approximately 34:1.
 This information is being provided for compliance purposes and is a reasonable estimate calculated in a manner consistent with SEC rules, based on our internal records and the methodology described above. The SEC rules for identifying the median compensated employee allow companies to adopt a variety of methodologies, to apply certain exclusions and to make reasonable estimates and assumptions that reflect their employee populations and compensation practices. Accordingly, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies have different employee populations and compensation practices and may use different methodologies, exclusions, estimates and assumptions in calculating their own pay ratios. Neither the Compensation Committee nor management of the Company used the Chief Executive Officer pay patio measure in making compensation decisions.

 All equity awards were granted pursuant to our 2011 Stock Option and Incentive Plan, as amended (the "2011 Plan"), or the 2021 Plan.

 (2)
 Each time-based stock option vests over a three-year period with one-third (1/3) of the shares subject to the award vesting on each of the first three anniversaries of the grant date, subject to the named executive officer's continued service to us through the applicable vesting date.

 (3)
 The PSOs granted to the named executive officers in 2023 vest as follows: (i) up to one-third (1/3) of the shares underlying the PSOs vest and become exercisable on each of the first three anniversaries of the grant date, provided that the volume weighted average price of the Company's common stock ("VWAP") equaled or exceeded certain levels; (ii) 33.33% of the shares underlying the PSOs were deemed to have satisfied the performance-based vesting and became eligible to vest over time because the VWAP exceeded $9.84; an additional 33.33% of the shares underlying the options were deemed to have satisfied the performance-based vesting and became eligible to vest over time because the VWAP equaled or exceeded $11.81; and the remaining 33.34% of the shares underlying the options will be deemed to have satisfied the performance-based vesting and will be eligible to vest over time if the VWAP equals or exceeds $13.77; and (iii) the failure to achieve any of the stock price hurdles applicable to a performance stock options during the three-year performance period will result in the applicable shares being forfeited. The shares that were earned based upon achievement of the performance-based hurdles are reported in the two columns to the left.

 (4)
 The PSOs granted to the named executive officers in 2024 were originally eligible to be earned and vest as follows: if the 30 day VWAP equaled or exceeded $7.50 prior to April 30, 2025, the shares underlying the options would have been earned and become eligible to vest in three equal annual installments on the first, second and third anniversaries of the grant date, subject to the named executive officer's continued service to us through the applicable vesting date. The stock price hurdle for these PSOs was not achieved and, on April 21, 2025, the Compensation Committee waived the stock price hurdle for the PSOs issued to Messrs.

 Employment Arrangements
 The Company and Mr. Marsh are parties to an employment agreement which renews automatically for successive one-year terms unless Mr. Marsh or the Company gives notice to the contrary. Mr. Marsh receives an annual base salary of $800,000 and is eligible to: (i) receive an annual incentive bonus targeted at an amount equal to 100% of his annual base salary; (ii) participate in all savings and retirement plans; and (iii) participate in all benefit plans and executive perquisites. Mr. Marsh's employment may be terminated by the Company with or without "Cause," as defined in his employment agreement, or by Mr. Marsh for "Good Reason," as defined in his employment agreement, or without Good Reason upon written notice of termination to the Company. If Mr. Marsh's employment is terminated by the Company without Cause, the Company is obligated to pay Mr. Marsh a lump sum equal to the sum of the following amounts: (a) one (1) times annual base salary, and (b) one (1) times the annual incentive bonus for the immediately preceding fiscal year.
 In addition, as of the date of termination, any restricted stock, stock options and other stock awards held by Mr. Marsh will accelerate and vest as if he had remained an employee for an additional twelve (12) months following the date of termination. Further, subject to Mr. Marsh's copayment of premium amounts at the active employees' rate, Mr. Marsh will be eligible to continue to participate in the Company's group health, dental, vision and life insurance programs for twelve (12) months following his termination. The agreement also provides that if, within twelve (12) months after a "Change in Control," as defined in his employment agreement,

 the Company terminates Mr. Marsh's employment without Cause or Mr. Marsh terminates his employment for Good Reason, then he is entitled to:
 (1)
 receive a lump sum payment equal to three (3) times the sum of (i) his current annual base salary plus (ii) his average annual incentive bonus over the three (3) fiscal years prior to the Change in Control (or his annual incentive bonus for the fiscal year immediately preceding to the Change in Control, if higher),

 (2)
 accelerated vesting of his stock options and other stock-based awards that would have vested had he remained an active employee for twelve (12) months following his termination, and

 (3)
 subject to Mr. Marsh's copayment of premium amounts at the active employees' rate, continued participation in the Company's group health, dental, vision and life insurance programs for twelve (12) months following such termination.

 The Company and Messrs. Shrestha, Middleton, Fullerton and Conway are each parties to an employment agreement with the Company pursuant to which, if the executive's employment is terminated by the Company without "Cause," as defined in the applicable employment agreement (and, in the case of Mr. Middleton, his employment is terminated due to the natural conclusion of the initial two-year term of his employment agreement without mutual agreement to extend the term for an additional year (the "Extended Term") or his employment is terminated at the natural conclusion of the Extended Term without mutual agreement to enter into a subsequent additional one-year period), the Company is obligated to pay the executive a lump sum amount equal to one (1) times or, in the case of Mr. Shrestha, 0.5 times, his annual base salary. In addition, as of the date of termination, all vested stock options held by the executive will be exercisable for twelve (12) months following the termination date. Further, for Mr. Conway, subject to the executive's copayment of premium amounts at the active employees' rate, the Company is required to continue paying its share of the premiums for the executive's participation in the Company's group health plans for twelve (12) months following his termination. In the case of Messrs. Shrestha, Middleton and Fullerton, they are entitled to have their group health insurance extend through the end of the month in which the date of termination occurs and the Company will either provide a lump sum payment or a monthly subsidy equal to twelve (12) times the Company's share of the monthly health insurance premium for the health insurance plan applicable on the date of termination.
 The employment agreements also provide that if, within twelve (12) months after a "Change in Control," as defined in the applicable employment agreement, the Company terminates such executive's employment without Cause or the executive terminates his employment for "Good Reason," as defined in the applicable employment agreement, then such executive shall be entitled to: (i) receive a lump sum payment equal to 100% of, or in the case of Mr. Shrestha 50% of, the sum of (i) his average annual base salary over the three (3) fiscal years immediately prior to the Change in Control (or the executive's annual base salary in effect immediately prior to the Change in Control, if higher) and his average annual bonus over the three (3) fiscal years prior to the Change in Control (or the executive's annual bonus in effect immediately prior to the Change in Control, if higher), (ii) accelerated vesting of his stock options and other stock-based awards that would have vested had he remained an active employee for twelve (12) months following his termination, (iii) subject to the executive's copayment of premium amounts at the active employees' rate, continued payment by the Company of its share of the premiums for the executive's participation in the Company's group health plans for twelve (12) months following the date of termination for Mr. Conway or, in the case of Messrs. Shrestha, Middleton and Fullerton, they are entitled to have their group health insurance extend through the end of the month in which the date of termination occurs and the Company will either provide a lump sum payment or monthly subsidy equal to twelve (12) times the Company's share of the monthly health insurance premium for the health insurance plan applicable on the date of termination, and (iv) all reasonable legal and arbitration fees and expenses incurred in obtaining or enforcing any right or benefit under the executive's employment agreement except in cases involving frivolous or bad faith litigation.
 Pursuant to the award agreements for the PSOs granted to the named executive officers, if a Sale Event occurs, the number of shares earned will be determined as of immediately prior to the sale event based on the sale price in the transaction. If the PSOs are not assumed, substituted or continued by the Company or its successor entity, and any earned shares underlying the PSOs will accelerate and vest as of immediately prior to the Sale Event. If the PSOs are assumed, substituted or continued in a Sale Event, the earned shares will vest on the earlier of (x) the original time-based vesting date and (y) the termination of the named executive officer's service relationship by the Company or its successor without "Cause" or by the named executive officer for "Good Reason" (each, as defined in the applicable award agreement).

 Potential Payments Upon Termination or Change in Control
 Messrs. Marsh, Shrestha, Middleton, Fullerton and Conway are parties to employment agreements with the Company that provide for potential payment and benefits upon certain qualifying terminations of employment as discussed above in "Employment Arrangements." In addition, the award agreements for the PSOs granted to each named executive officer provide for potential acceleration of vesting in connection with a Sale Event, as also described above in "Employment Arrangements."
 Severance payments and benefits under the employment agreements are subject to the executive signing a general release of claims in a form and manner satisfactory to the Company and such release becoming effective. An executive is not entitled to receive any such payment or benefits in the event he breaches the Employee Patent, Confidential Information and Non-Compete Agreement referenced in the executive's respective employment agreement or any non-compete, non-solicit or non-disclosure covenants in any agreement between the Company and such executive. We agreed to provide severance payments to such executives in these circumstances based on our negotiations with each of our executives at the time he joined our Company, or as negotiated subsequent to hiring, and in order to provide a total compensation package that we believe to be competitive. Additionally, we believe that providing severance upon a termination of employment without Cause can help to encourage our executives to take the risks that we believe are necessary for our Company to succeed and also recognize the longer hiring process typically involved in hiring a senior executive. If Mr. Marsh had been terminated without Cause on December 31, 2024 and such termination was not within twelve (12) months following a Change in Control, the approximate value of the severance package, including, as described above in "Employment Arrangements," salary, benefits and accelerated vesting of equity awards, under his employment agreement would have been $926,330. If Messrs. Shrestha, Middleton, Fullerton or Conway, had been terminated without Cause on December 31, 2024 and such termination was not within twelve (12) months following a Change in Control, the approximate value of the severance packages, including, as described above in "Employment Arrangements," salary, benefits and accelerated vesting of equity awards, under the respective employment agreement for such named executive officer would have been as follows: Mr. Shrestha — $339,467, Mr. Middleton — $698,542, Mr. Fullerton — $567,815 and Mr. Conway — $526,664.
 Messrs. Marsh, Shrestha, Middleton, Fullerton and Conway are parties to employment agreements with the Company, respectively, that provide for a potential payment upon a termination of employment by the Company without Cause or a resignation by the executive for Good Reason within twelve (12) months following a Change in Control, as described above in "Employment Arrangements." Such payments by the Company to any of the executives are subject to the executive signing a general release of claims in a form and manner satisfactory to the Company and the effectiveness of such release. An executive is not entitled to receive any such payment in the event he breaches the Employee Patent, Confidential Information and Non-Compete Agreement referenced in each executive's respective employment agreement or any non-compete, non-solicit or non-disclosure covenants in any agreement between the Company and such executive.
 We agreed to provide payments to these executives in these circumstances in order to provide a total compensation package that we believe to be competitive. Additionally, the primary purpose of our equity-based incentive awards is to align the interests of our executives and our stockholders and provide our executives with strong incentives to increase stockholder value over time. As change in control transactions typically represent events where our stockholders are realizing value for their equity interests in our Company, we believe it is appropriate for our executives to share in this realization of stockholder value, particularly where their employment is terminated in connection with the change in control transaction. We believe that this will also help to better align the interests of our executives with our stockholders in pursuing and engaging in these transactions.
 If a Change in Control had occurred on December 31, 2024 and on that date the employment of Mr. Marsh, Mr. Shrestha, Mr. Middleton, Mr. Fullerton and Mr. Conway had been terminated by the Company without Cause or the executive had resigned for Good Reason, the value of the of the severance packages, including, as mentioned above in "Employment Arrangements," salary, benefits and accelerated vesting of equity awards, under the employment agreements and PSOs awards for each such named executive officer would have been as follows: Mr. Marsh — $3,101,138, Mr. Shrestha — $393,493, Mr. Middleton — $3,575,984, Mr. Fullerton — $562,527 and Mr. Conway — $643,744. The employment agreements provide for a modified cutback such that, any payments or benefits payable under the employment agreements or otherwise would be subject to the excise tax imposed by Section 4999 of the Code, the executive will receive the greater after-tax amount of either: (i) the full payment or (ii) a reduced payment that does not give rise to the excise tax imposed by Section 4999 of the Code. The foregoing numbers do not reflect any cutback. None of the executives are entitled to any tax gross- up payments related to severance payments or otherwise.

 DIRECTOR COMPENSATION
 The Compensation Committee periodically reviews the Company's Non-Employee Director Compensation Plan (the "Director Compensation Plan") to ensure that the compensation paid to non-employee directors aligns the directors' interests with the long-term interests of the stockholders and that the structure of the compensation is simple, transparent, and easy for stockholders to understand. The Compensation Committee also considers whether the Director Compensation Plan fairly compensates the Company's directors when considering the workload and commitment required in a company of the size, scope and complexity of Plug Power, and considers general market compensation levels for directors to determine whether our director compensation is reasonable and competitive to attract highly qualified and talented individuals to serve on our Board. Employee directors do not receive additional compensation for their services as directors. The Company reimburses all reasonable out-of-pocket expenses incurred by directors for their attendance at meetings of our Board or any committee thereof.
 Pursuant to the Director Compensation Plan, upon initial election or appointment to the Board, each non-employee director receives an initial, one-time award of a non-qualified stock option to purchase a number of shares equal to $225,000 divided by the closing price of our common stock on the grant date, with an exercise price equal to the fair market value of our common stock on the grant date, that vests in full on the first anniversary of the grant date, subject to continued service through such date. The initial award expires ten (10) years from the grant date. Notwithstanding the foregoing, all shares of our common stock subject to such non-qualified stock option will become fully vested and exercisable, subject to the non-employee director's continued service relationship through the consummation of a "Sale Event," as defined in the 2021 Plan, immediately prior to the consummation of such Sale Event. In addition, pursuant to the Director Compensation Plan, each year of a non-employee director's tenure, a director (other than any director receiving an initial award upon initial election or appointment to the Board) receives an equity grant comprised of (i) a non-qualified stock option to purchase a number of shares equal to $112,500 divided by the closing price of our common stock on the date of the grant and (ii) a number of shares of restricted common stock equal to $112,500 divided by the closing price of our common stock on the grant date. The stock option portion of the grant expires ten (10) years from the grant date and has an exercise price equal to the fair market value of our common stock on the grant date. The annual stock option and restricted common stock awards vest in full upon the earlier of the first anniversary of the grant date or the date of the next annual meeting which is at least fifty (50) weeks after the immediately preceding year's annual meeting, subject to continued service through such date. Notwithstanding the foregoing, all such shares of restricted common stock and stock options will become fully vested, subject to the non-employee director's continued service relationship through the consummation of a Sale Event, immediately prior to the consummation of such Sale Event.
 During the fiscal year ended December 31, 2024, the Chairman of the Board received a $125,000 annual retainer for service as Chairman of the Board, other Board members received a $60,000 annual retainer for service on the Board and committee members received annual retainers for their service on committees of the Board in accordance with the following table:

 The total amount of the annual retainer is paid in a combination of 50% cash and 50% in shares of the Company's common stock, provided that directors may elect to receive a greater portion (up to 100%) of the total retainer in common stock. At the discretion of the Compensation Committee, directors may elect to receive up to 80% of their annual retainer in cash. All common stock issued for the annual retainers is fully vested at the time of issuance and is valued at its fair market value on the date of issuance.

 The Board has adopted a written related party transaction policy that requires the Company's General Counsel, together with outside counsel as necessary, to evaluate potential transactions in which the Company is a participant and in which a related party or an affiliate of a related party has an interest prior to the Company entering into any such transaction to determine whether such contemplated transaction requires the approval of the Board, the Audit Committee, both or neither. The policy defines a "related party" as: (i) the Company's directors or executive officers, (ii) the Company's director nominees, (iii) security holders known to the Company to beneficially own more than 5% of any class of the Company's voting securities, or (iv) the immediate family members of any of the persons listed in items (i) – (iii).
 Other than as otherwise disclosed herein, since January 1, 2024, there was no transaction or series of similar transactions to which the Company was or will be a party in which the amount involved exceeded or will exceed $120,000 and in which any related party had or will have a direct or indirect material interest.
 Director Independence
 As a result of our common stock being listed on Nasdaq, we must comply with the applicable rules of such exchange in determining whether a director is independent. We have determined that each of Messes. Helmer and Mahtani, Dr. Kenausis and Messrs. Bonney, McNamee, Joggerst, Angle and Willis qualifies as "independent" as defined under applicable SEC rules and Nasdaq listing standards.
