Dear Stockholder,
You are cordially invited to attend the annual meeting of stockholders (“Annual Meeting”) of Clean Energy Fuels Corp. (the “Company,” “Clean Energy,” “we,” “us” or “our”) on Thursday, May 19, 2022,16, 2024, at 8:00 a.m. Pacific Time. The Annual Meeting will be a virtual meeting conducted via live audio webcast that can be accessed by visiting www.virtualshareholdermeeting.com/CLNE2022CLNE2024. At this website, you will be able to listen to the Annual Meeting live, submit questions for our management, directors and representatives of our independent registered public accounting firm in attendance, and submit your vote while the Annual Meeting is being held.
2021 turned outTo be a leader in any field, you must always find new ways to innovate and inspire.
Clean Energy strives to do just that.
During the Company’s early years, we worked with municipalities to help clean the air by transitioning their fleets of buses, airport support vehicles, and waste collection trucks from dirty diesel to cleaner burning natural gas. The results can be seen in bluer skies around the country.
In 2013, we pioneered a new type of fuel, renewable natural gas (“RNG”), that reduces smog-forming tailpipe emissions and greenhouse gas emissions, providing the transportation industry with an immediate solution to address climate change. Today, virtually all the fuel that we sell at our stations is RNG, allowing our customers’ fleets to dramatically lower their carbon footprint.
We believe so strongly in the sustainable power of RNG, that we made the decision several years ago to invest directly in its production. By partnering with dairy owners, we can help mitigate the critical problem of fugitive methane produced from cow manure, one of the most groundbreakingpotent greenhouse gases. In 2023, we reached an important milestone by completing our first dairy RNG production facility that captures methane and turns it into a valuable transportation fuel, all while providing additional benefits to the dairy’s operations, such as organic nutrients, reduced odor, and improved water quality.
We feel very fortunate at Clean Energy to be in the Company’s history. We believebusiness of helping our decisioncustomers meet their sustainability goals.
As a longtime LA Dodgers fan, let me say that we were thrown a curveball at the beginning of 2023 that would make Clayton Kershaw envious. Due to rapidly accelerate our renewableextraordinary circumstances, including a protracted cold spell in California, natural gas (RNG) offering will play a big roleprices shot through the roof in the state, which is our customers’ ability to achieve their sustainability goals by significantly reducing greenhouse gas emissions produced by their fleets.
largest market, increasing 10-fold at one point. We expect to bewere able to meet the growing demand for this incredibly clean fuel well into the future by investing in the production of additional RNG sources with our joint venture partners, TotalEnergies and bp. We cemented these two joint ventures in early-2021 and quickly went to work signing partnerships with dairy owners around the country. I had the privilege of meeting with a number of them and most, if not all, are family run dairy farms with multiple generations involved in the operations. These are hard-working men and women who have a passion to run their operations in the most environmentally-friendly way. The idea of turning the manure from their cows into a clean fuel that will operate fleets of refuse trucks, city buses or heavy-duty trucks is very appealing to them.
The additional RNG from these dairies, which is rated cleaner than even electric vehicles, will allow us to expand our current customer roster, which includespass some of the largestexpense to our customers, but we had to absorb much of it, which impacted our bottom line for the first two quarters.
Thankfully the fundamentals of our business are strong, and we were able to bounce back with a solid second half of the year. Our overall financial results for 2023 might not be what we had hoped going into it, but we believe the wind is to our backs and we have considerable momentum going into 2024 and beyond.
One of the most significant developments that began to unfold last year was the introduction of several Cummins X15N test engines. This is crucial for the alternative fuels heavy-duty vehicle market because it’s the first 15-liter engine to operate on RNG, capable of delivering the power, torque, and range that many heavy-duty trucks require. Some of the most well-known fleets in the country, like Walmart, Werner, UPS, Amazon, UPS, Republic Services and Knight Transportation, began to put the transit agenciesX15N to the test, driving it over the most difficult terrains and challenging routes. I’m pleased to say that the reviews have been extremely favorable.
Commercialization of the X15N engine will begin later in New York City2024, but in my many years of partnering with Cummins on their natural gas engines, I’ve never heard the world-class engine manufacturer be so bullish about the potential of one of their new products. The heavy-duty truck market is desperately searching for an alternative to diesel that can meet their emissions reduction goals, yet have been disappointed by the



cost, availability, and Los Angeles.lack of necessary fueling/charging associated with other technologies including electric and hydrogen. We strongly believe the X15N, fueled by RNG, is the answer.
AsThe timing of this new engine couldn’t be better. Over the last several years, Clean Energy has significantly expanded its fueling footprint in prime locations for heavy-duty trucking. By the end of 2023, we completed the construction of 18 of the 19 stations contracted by Amazon for their new nationwide heavy-duty fleet. The beauty of these stations is that we have an anchor customer in Amazon to pay for them, while being strategically located and open to other fleets.
Another market that is eagerly awaiting the new Cummins X15N is Canada. And once again, Clean Energy is well-posed to take advantage of this important transportation market. In April of last year, we announced an exciting strategic partnership with Tourmaline, Canada’s leading energy company, to construct up to 20 fueling stations, first across the western part of the country, with the potential of expanding east. With its long stretches between cities and active as 2021 was, I am evenmountainous terrain, heavy-duty trucks in Canada need a larger engine. The X15N will be a perfect fit for this environmentally conscious market.
The over-the-road market is not the only one making the switch to cleaner burning fuels. Our relationship with Pasha, the shipping company that services the Hawaiian market, continues to expand. We are now providing liquified natural gas (“LNG”) from our plant in Boron, California for three Pasha container ships that make their way from the Ports of Long Beach and Oakland to Honolulu. When running at full capacity, these large ships use an average of 460,000 gallons of LNG every week and are reducing their diesel particulate matter and sulfur oxide by 99%, their nitrogen oxides by 90%, and carbon dioxide by 25% compared to traditional shipping fuels.
There’s much more to be optimistic about 2022, which marks Clean Energy’s 25th anniversary.future. But I will wrap up by emphasizing that we are extremely well positioned to continue to be the leader in the transitioning energy market. We were onestrengthened our balance sheet at the end of 2023 with a $300 million secured term loan from Stonepeak, a leading infrastructure firm, and can draw an additional $100 million. We believe the first companies to offer transportation fleets a solution to tackleinvestments we have made both in the problemupstream and downstream RNG markets will keep us ahead of dirty air and now we’re giving them a powerful tool to addressany competitor. And most of all, we have the issuebest team in the business of our changing climate with RNG.whom I couldn’t be prouder.
We are pleased to take advantage of laws and rules that allow issuers to make use of the Internet in conducting a meeting of stockholders, as well as in furnishing proxy materials. As a result, we will not only host the Annual Meeting virtually on the Internet, but we will also furnish the proxy materials for the Annual Meeting to our stockholders on the Internet. We believe this use of the Internet meaningfully lowers our costs, increases efficiencies and helps reduce the environmental impact of the Annual Meeting, while permitting and encouraging increased stockholder attendance and engagement.

Virtual Annual Meeting
We have held our annual meetings of stockholders virtually since 2017, and we have again elected to holdwill be holding this year’s Annual Meeting virtually on the Internet. We have made this decision for a number of reasons, including:

The attendance at our most recent in-person stockholder meetings was low, consisting of an average of 12 stockholders whom attended each of our three most recent in person meetings. The most recent suchNo physical meeting was in 2017, when we held a “hybrid” meeting that included both in-person and virtual access to the meeting. Despite these historically low in-person attendance levels, offering in-person access to our stockholder meetings can involve significant costs, including monetary expenses and increased management and employee time. As a result, we determined that offering in-person access to the Annual Meeting would not provide sufficient benefits to our stockholders to justify the associated costs.

Attendance at our stockholder meeting held in 2021, which included a virtual component, increased substantially. The number of stockholders who attended our 2021 annual meeting of stockholders via the Internet rose to 455 stockholders. In light of this increase in attendance, we believe the virtual meeting format, which allows our stockholders to attend meetings from their locations around the world, is an effective way to encourage and enable more of our stockholders to participate in our annual meeting process. As a result, we determined to host the Annual Meeting virtually in order to support similar or further increased stockholder attendance levels at this year’s meeting.

will be held. Stockholders who attend the Annual Meeting virtually will be able to listen to the meeting live and submit their vote while the Annual Meeting is being held, and will also be able to submit, either anonymously or identified by name, questions or comments for our management, directors and representatives of our independent registered public accounting firm in attendance at the meeting. This functionality provides our stockholders with opportunities for participation and engagement at the Annual Meeting that are comparable to those that would be available at an in-person meeting. As a result, we believe the virtual nature of the Annual Meeting will not decrease engagement capabilities and could facilitate increased stockholder participation with the ability to submit comments and questions anonymously if a stockholder desires to do so.

During the Annual Meeting, we will answer as many stockholder-submitted questions as time permits, other than questions that are irrelevant to the purpose of the Annual Meeting or our business or that contain inappropriate or derogatory references that are not in good taste. Any appropriate questions that we are unable to address during the Annual Meeting will be published on our website following the meeting. If we receive substantially similar questions, we will group them together and provide a single response to avoid repetition.references.

We are sensitive to the public health and travel concerns stockholders may have regarding the coronavirus (COVID-19). Accordingly, we believe that holding this year’s Annual Meeting virtually is prudent in order to mitigate the health and safety risks to our stockholders while also facilitating stockholder attendance and participation at the Annual Meeting.
Stockholders who choose to attend the Annual Meeting will do so by accessing a live audio webcast of the Annual Meeting via the Internet at www.virtualshareholdermeeting.com/CLNE2022CLNE2024. Please see “Attending the Virtual Annual Meeting” below for more information.
Record Date and Outstanding Shares
All stockholders that owned shares of our common stock at the close of business on March 22, 2022,2024 (the “Record Date”), the date fixed by the Board as the record date, are entitled to vote at the Annual Meeting.
On the record date, 222,713,200Record Date, 223,263,055 shares of our common stock were outstanding.
Voting Matters
Voting Rights
Each share of our common stock entitles the owner of the share to one vote on all matters to be voted on at the Annual Meeting.

Quorum Requirement
We will have the required quorum to conduct the business of the Annual Meeting if holders as of the record dateRecord Date representing a majority of the outstanding shares of our common stock entitled to vote are present in person or represented by proxy at the Annual Meeting. Abstentions and broker non-votes (discussed under “Effect of Not Providing Voting Instructions; Broker Non-Votes” below) will be counted for purposes of determining the presence of a quorum at the Annual Meeting.
Effect of Not Providing Voting Instructions; Broker Non-Votes
Stockholders of Record.   You are a “stockholder of record” if your shares are registered directly in your name with Computershare Trust Company, N.A., our transfer agent. If you were a stockholder of record at the close of business on the record date for the Annual MeetingRecord Date and you submit a valid proxy but do not provide voting instructions with respect to your shares, all shares represented by your proxy will be voted in accordance with the recommendation of our Board on each proposal to be presented at the Annual Meeting, as described in this Proxy Statement.
Beneficial Owners of Shares Held in Street Name.   You are a “beneficial owner of shares held in street name” if your shares are not held of record in your name but are held by a broker, bank or other nominee on your behalf as the beneficial owner. Pursuant to applicable stock exchange rules, if your shares were held in street name through a brokerage account at the close of business on the record date for the Annual Meeting,Record Date, you must provide voting instructions to your broker if you want your shares to be voted on the election of directors (Proposal 1), the approval, on an advisory, non-binding basis, of the compensation of our named executive officers (Proposal 3) and the approval of our New ESPP2024 Performance Incentive Plan (Proposal 4). These proposals constitute “non-routine” matters on which a broker is not entitled to vote shares held for a beneficial owner without receiving voting instructions from the beneficial owner. The ratification of the appointment of KPMG LLP as our independent registered public accounting firm (Proposal 2) is considered a “routine”

matter for which your shares may be voted in the discretion of your broker if voting instructions have not been received. As a result, if you hold your shares in street name and you do not submit voting instructions to your broker, your broker may exercise its discretion to vote on Proposal 2 at the Annual Meeting but will not be permitted to vote on Proposal 1, Proposal 3 or Proposal 4 at the Annual Meeting. In recent years, however, several large brokers, such as Charles Schwab and TD Ameritrade have announced that they have eliminated discretionary voting for even “routine” matters. Therefore, if you hold your shares through such brokers, then your shares might not be voted, even for “routine” matters if you do not give voting instruction to your broker. Therefore,Consequently, we urge every stockholder to vote their shares. If your broker does exercise this discretion, your shares will be counted as present for determining the presence of a quorum at the Annual Meeting and will be voted on Proposal 2 in the manner directed by your broker, but your shares will constitute “broker non-votes” on each of the other items at the Annual Meeting. Moreover, if you are a beneficial owner of shares in street name and you properly submit a voting instruction form to your broker, bank or other nominee that is signed but unmarked with respect to your vote on Proposals 1, 2, 3 or 4, applicable rules will generally permit your broker, bank or other nominee to vote your shares on these proposals in accordance with the recommendations of the Board as set forth in this Proxy Statement.
Voting Requirements
The election of directors (Proposal 1) will be determined by a plurality of the votes cast on the proposal at the Annual Meeting. This means that the tennine nominees who receive the highest number of affirmative votes will be elected as directors. Shares voted “Withhold” and broker non-votes are not counted as votes cast and will have no effect on the outcome of the election of directors.
The ratification of the appointment of KPMG LLP as our independent registered public accounting firm (Proposal 2), the approval, on an advisory, non-binding basis, of the compensation of our named executive officers (Proposal 3), and the approval of our New ESPP (Proposal 4)2024 Performance Incentive Plan must each be approved by the affirmative vote of a majority of the votes cast on the proposal at the Annual Meeting. For purposes of determining the number of votes cast for Proposals 2, 3 and 4, only shares voted “FOR” or “AGAINST” are counted. Abstentions and broker non-votes are not treated as votes cast and will not be counted in determining the outcome of Proposal 2, Proposal 3 or Proposal 4.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
The two tables below show the beneficial ownership of certain persons with respect to our common stock, our only outstanding class of voting securities. Except as indicated by the footnotes to these tables, we believe, based on the information furnished or otherwise available to us, that the persons and entities named in these tables have sole voting and investment power with respect to all shares of common stock shown as beneficially owned by them, subject to applicable community property laws.
We have determined beneficial ownership as shown in these tables in accordance with the rules of the SEC. In accordance with these rules, in computing the number of shares of our common stock beneficially owned by a person and the percentage ownership of that person, we deemed to be outstanding all shares of our common stock subject to (1) stock options held by that person that are currently exercisable or exercisable within 60 days after March 22, 2022,2024, and (2) restricted stock units (“RSUs”) held by that person that are subject to vesting and settlement within 60 days after March 22, 2022.2024. We did not, however, deem these shares outstanding for the purpose of computing the percentage ownership of any other person. We calculated percentage ownership as shown in these tables based on 222,713,200223,263,055 shares of our common stock outstanding on March 22, 2022.2024. The information in these tables is not necessarily indicative of beneficial ownership for any other purpose, and the inclusion of any shares in these tables does not constitute an admission of beneficial ownership of the shares.
The following table shows the amount and percentage of our common stock beneficially owned by each holder of more than 5% of the outstanding shares of our common stock:

Selecting Our Director Nominees
Under its charter and our corporate governance guidelines, our nominating and corporate governance committee is responsible for reviewing with the Board, on an annual basis, the requisite skills and characteristics of potential new Board members, as well as the composition of the Board as a whole. This assessment includes an analysis of each member’s qualifications as a director and each member’s independence, as well as consideration of age, experience and other diversity factors in the context of the needs of the Board.
Minimum Criteria
Pursuant to our corporate governance guidelines, a majority of our directors must meet the standards for independence as required by Nasdaq, and no director may serve on more than three other public company boards of directors unless approved in advance by the Board. Further, applicable Nasdaq rules provide that at least one member of our Board must meet the criteria for an “audit committee financial expert” as defined by SEC rules, and the members of certain of our Board committees must satisfy enhanced independence and financial expertise standards under applicable Nasdaq and SEC rules. We also believe all directors should possess the following attributes:


Professional ethics and values, consistent with our code of ethics (described below under “Corporate Governance — Code of Ethics”);

12




A commitment to building stockholder value;


Business acumen and broad experience and expertise at the policy-making level in one or more of the areas of particular consideration described under “Key Qualifications, Skills and Attributes” below;


The ability to provide insights and practical wisdom based on the individual’s experience or expertise; and


Sufficient time to effectively carry out duties as a Board member.
Other than the foregoing, there are no stated minimum criteria for director nominees, and the nominating and corporate governance committee may consider these factors and any such other factors as it deems appropriate. The nominating and corporate governance committee does, however, review the activities and associations of each potential director candidate to ensure there is no legal impediment, conflict of interest or other consideration that might hinder or prevent service on our Board.
Diversity
Although we do not have a formal policy with respect to Board diversity, the nominating and corporate governance committee strives to assemble a board of directors that brings to our Company a variety of perspectives, skills and expertise. To achieve this, the nominating and corporate governance committee considers individuals from various disciplines and backgrounds in recommending director nominees to the

12


Board, including diversity characteristics that may be self-identified by directors or director nominees, such as race, gender, military service, or other socioeconomic or demographic characteristics. The nominating and corporate governance committee also seeks to recommend directors who possess a broad range of business, professional, governmental, community involvement and natural gas and energy industry experience.
The nominating and corporate governance committee assesses these and other factors as it deems appropriate in connection with its annual review of each director and the Board as a whole and takes these factors into account when determining whether to nominate existing directors for re-election in connection with this annual review. The nominating and corporate governance committee also takes these factors into account when considering any director nominee outside of its annual review process, such as when a vacancy exists on the Board or when a stockholder suggests a new director candidate that the committee or the Board decides to consider for a mid-year appointment. In addition, as part of its annual self-evaluation process, the nominating and corporate governance committee assesses its consideration of diversity in identifying and evaluating director candidates, including the key qualifications, skills and attributes that it aims for directors to possess.
The nominating and corporate governance committee is committed to further diversifying the Board across a number of metrics, including gender and representatives of underrepresented communities. Our Board has appointed three female directors since 2019, including Ms. Lizabeth Ardisana in December 2019, and each of Ms. Karine Boissy-Rousseau in December 2021, and Ms. Lorraine Paskett in December 2021. Three2021 (who resigned in May 2023). Two of our tennine current directors are female and twoone of our tennine current directors self-identify as an “underrepresented minority” as such term is defined by Nasdaq Listing Rule 5605(f); among the nine directors nominated for election in this Proxy Statement, two are female and one self-identifies as an “underrepresented minority” as such term is defined by Nasdaq Listing Rule 5605(f).
Board Refreshment
Board members with a diversity of life experiences, backgrounds and gender are important to bring a variety of perspectives to our Board, as discussed above under “Diversity.” We aim to regularly bring new directors to our Board at a responsible pace to ensure the Board benefits from fresh ideas and perspectives, while balancing the importance of directors who have experience with our Company.
Board refreshment is a key matter considered during our annual Board and committee self-evaluations. We have refreshed a majority of our Board since 2018, including the retirement of three long-tenured directors and the appointment of three female directors since 2020.2018. The average tenure of our Board members is eight (8)eleven (11) years.

13


Key Qualifications, Skills and Attributes
The nominating and corporate governance committee regularly reviews the appropriate skills and characteristics required of Board members in the context of the composition of the Board, our operating requirements, and the long-term interests of stockholders. When conducting its review of the key qualifications, skills and attributes desired of Board members, the nominating and corporate governance committee particularly considers:
Senior Leadership Experience:Board members who have served in senior leadership positions, such as a chief executive officer, chairman, senior executive, or leader of significant operations, are important to us because they have the experience and perspective to analyze, shape and oversee the execution of important strategic, operational and policy issues. These Board members’ insights and guidance, and their ability to assess and respond to situations encountered by our Board, may be enhanced by leadership experience at complex businesses or organizations.
RNG and Conventional Natural

Gas and Industry Experience:
Because we are seeking to drive adoption of RNG and conventional natural gas as a vehicle fuel by fleet vehicle operators, primarily in the trucking, airport, refuse, public transit, industrial and institutional energy user and government fleet markets, relevant education or experience in our industry is key for understanding our markets, strategy, risk management and operations.

13


Government, Legal, Public Policy and Regulatory Expertise:Board members who have served in government positions provide experience and insights that help us work constructively with governments and address significant public policy issues. Board members with a background in law can assist the Board and legal team in fulfilling its oversight responsibilities regarding our legal and regulatory compliance and our engagement with regulatory authorities.
Financial Expertise:Knowledge of financial markets, financing and funding operations and accounting and financial disclosure and reporting processes is important to have well-represented on our Board. This experience helps our Board members in understanding and overseeing our capital structure, financing and investing activities, as well as our financial reporting and internal controls.
Public and Private Company

Board Experience:
Board members with public and private company board experience understand the dynamics and operations of a corporate board. These matters include the relationship of a company board with senior management personnel, the legal and regulatory landscape in which companies must operate, the importance of particular agenda and oversight issues, and how to oversee an ever-changing mix of strategic, operational and compliance-related matters.
From time to time, the nominating and corporate governance committee will also consider such other qualifications, skills and attributes as it deems appropriate given the needs of the Board and the Company to maintain a balance of knowledge, experience, background and capability.
Director Nominee Evaluations
At least annually, our nominating and corporate governance committee leads an evaluation of each of our directors and our Board as a whole and each of its committees. In evaluating whether a current director should continue to serve on our Board, the nominating and corporate governance committee considers a number of factors, including the minimum criteria and diversity goals described above and each director’s qualifications, skills and attributes in the areas identified by the committee as particularly important to our Board. In concluding that each of the director nominees should continue to serve as directors of the Company, the nominating and corporate governance committee considered their knowledge, experience and

14


expertise in these areas as indicated in the table below, which they gained from their professional backgrounds described under “Director Nominees” above.

PROPOSAL 3
ADVISORY, NON-BINDING VOTE TO APPROVE EXECUTIVE COMPENSATION
The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (“Dodd-Frank Act”) enables our stockholders to vote to approve, on an advisory, non-binding basis, the compensation of our named executive officers as disclosed in this Proxy Statement in accordance with the SEC’s compensation disclosure rules.
As described in detail under “Compensation Discussion and Analysis” below, our executive compensation program is designed to attract, retain and motivate talented and dedicated executive officers; to reward individual performance and achievement of key corporate objectives without promoting excessive or unnecessary risk-taking; to align the interests of our executives with those of our stockholders; and to provide compensation that we believe is fair in light of an executive’s experience, responsibilities, performance and tenure with our Company and in relation to the compensation provided to other executives of our Company and certain peer companies. Under this program, determinations regarding each named executive officer’s compensation are based on, among other factors, the individual’s performance and contribution to our strategic plans and other business objectives; the Company’s overall performance, in light of business and industry conditions; general industry benchmarks and trends, including the compensation practices of certain peer companies; the level of the individual’s responsibility; the seniority of the individual; the individual’s long-term commitment to our Company; the available pool of individuals with similar skills; principles of pay equity and relative pay; the role of each compensation component in achieving the objectives of our executive compensation program; and the compensation committee’s business judgment and experience. Please read the “Compensation Discussion and Analysis” beginning on page 32in this Proxy Statement for additional details about our executive compensation program.
We are asking our stockholders to indicate their support for our named executive officer compensation as described in this Proxy Statement. We believe the compensation of our named executive officers is appropriate and serves to both incentivize and retain our highly skilled executive leadership team. Attracting, retaining and motivating key executives is crucial to our success. This say-on-pay proposal gives our stockholders the opportunity to indicate whether they approve of our named executive officers’ compensation. This vote is not intended to address any specific component of compensation, but rather relates to the overall compensation of our named executive officers and our executive compensation philosophy, policies and practices described in this Proxy Statement in accordance with the SEC’s compensation disclosure rules. Accordingly, we ask that our stockholders vote “FOR” the following resolution at the Annual Meeting:
“RESOLVED, that the Company’s stockholders approve, on an advisory, non-binding basis, the compensation of the Company’s named executive officers, as disclosed in the Company’s Proxy Statement for its 20222024 Annual Meeting of Stockholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the Summary Compensation Table and the other related tables and disclosure included therein.”
This say-on-pay proposal is being provided as required by Section 14A of the Exchange Act and is advisory and therefore not binding on the Company, the compensation committee or our Board in any way. Our Board and our compensation committee value the opinions of our stockholders, and to the extent there is any significant vote against the named executive officer compensation as disclosed in this Proxy Statement, we will consider our stockholders’ concerns and the compensation committee will evaluate whether any actions are necessary to address these concerns.

As a result, we will conduct an opportunity toadvisory vote on executive compensation annually at least until the compensationnext stockholder advisory vote on frequency of our named executive officers each year at the annual meeting of stockholders.such votes.

PLAN
General
At the Annual Meeting, stockholders will be asked to approve the 2022 Employee Stock PurchaseClean Energy Fuels Corp. 2024 Performance Incentive Plan and the reservation of 2,500,000 shares of our common stock for issuance under the New ESPP. The New ESPP(the “2024 Plan”), which was adopted, by the Board, subject to stockholder approval, by our Board on April 6, 2022.March 27, 2024.
The Company believes that incentives and stock-based awards focus employees on the objective of creating stockholder value and promoting the success of the Company, and that incentive compensation plans like the proposed 2024 Plan are an important attraction, retention and motivation tool for participants in the plan.
The Company currently maintains the Clean Energy Fuels Corp.

Our Board believes that the number of shares currently available under the 2016 Plan does not give the Company sufficient authority and flexibility to adequately provide for future incentives. If stockholders approve the 2024 Plan, no new awards will be granted under the 2016 Plan after the Annual Meeting. In that case, the number of shares of the Company’s common stock that remain available for award grants under the 2016 Plan immediately prior to the Annual Meeting will become available for award grants under the 2024 Plan. An additional 4,000,000 shares of the Company’s common stock will also be made available for award grants under the 2024 Plan.

If stockholders approve the New ESPP,2024 Plan, the first offering periodtermination of our grant authority under the New ESPP is expected to begin on July 1, 2022.2016 Plan will not affect awards then outstanding under that plan.

No Repricing.   In no case (except due to an adjustment to reflect a stock split or other event referred to under “Adjustments” below, or any repricing that may be approved by stockholders) will the Administrator (1) amend an outstanding stock option or stock appreciation right to reduce the exercise price or base price of the award, (2) cancel, exchange, or surrender an outstanding stock option or stock appreciation right in exchange for cash or other awards for the purpose of repricing the award, or (3) cancel, exchange, or surrender an outstanding stock option or stock appreciation right in exchange for an option or stock appreciation right with an exercise or base price that is less than the exercise or base price of the original award.
Minimum Vesting Requirement.   All awards granted under the 2024 Plan are subject to a minimum vesting requirement of one year and no portion of any award may vest earlier than the first anniversary of the grant date of the award. This minimum vesting requirement does not apply to 5% of the total number of shares under the 2024 Plan and does not limit or restrict the Administrator’s discretion to accelerate the vesting of any award in circumstances it determines to be appropriate.
Eligibility.   Persons eligible to receive awards under the 2024 Plan include officers or employees allof the Company or any of its subsidiaries, directors of the Company, and certain consultants and advisors to the Company or any of its subsidiaries. As of March 15, 2024, approximately 525 officers and employees of the Company and its subsidiaries (including all of the Company’s named executive officers), and each of the members of the Board who are eligible to participate in the New ESPP, except that the Plan Administrator may exclude from an offering period any individual who is regularly expected to work less than twenty hours per week or less than five months per calendar year in the employ ofnot employed by the Company or any subsidiary, any individual who has been employed less than 2 years, and certain highly compensated employeesof its subsidiaries (“Non-Employee Directors”), were considered eligible under the 2024 Plan.

Aggregate Share Limit.   The maximum number of shares of the CompanyCompany’s common stock that may be issued or transferred pursuant to awards under the 2024 Plan equals the sum of the following (such total number of shares, the “Share Limit”):

4,000,000 shares, plus

the number of shares available for additional award grant purposes under the 2016 Plan as of the date of the Annual Meeting and determined immediately prior to the termination of the authority to grant new awards under that plan as of the date of the Annual Meeting, plus

the number of any subsidiary. An eligible employee may only join an offering periodshares subject to stock options granted under the 2016 Plan or the 2006 Plan and outstanding as of the date of the Annual Meeting which expire, or for any reason are cancelled or terminated, after the date of the Annual Meeting without being exercised (which, for purposes of clarity, will become available for award grants under the 2024 Plan on a one-for-one basis), plus

the number of any shares subject to restricted stock and restricted stock unit awards granted under the 2016 Plan or the 2006 Plan that are outstanding and unvested as of the date of the Annual Meeting which are forfeited, terminated, cancelled, or otherwise reacquired after the date of the Annual Meeting without having become vested (with any such shares taken into account based on the start date of that period. Subsidiaries include any subsidiary corporation of the Company, whether now existing or hereafter organized, which elects, with the approval of the Plan Administrator, to extend the benefits of the New ESPP to their eligible employees. Employees who are citizens or residents of a non-U.S. jurisdiction (without regard to whether he or she is also a citizen of the United States or a resident alien (within the meaning of Section 7701(b)(1)(A) of the Internal Revenue Code of 1986 (“Code”)) are ineligible to participate in the New ESPP if his or her participation is prohibited under the laws of the applicable non-U.S. jurisdiction or if complying with the laws of the applicable non-U.S. jurisdiction would cause the New ESPP or an offering to violate Section 423 of the Code.premium share-counting rule discussed below for full-value awards).
As of March 15, 2022, 4 executive officers2024, approximately 964,392 shares were available for additional award grant purposes under the 2016 Plan, approximately 19,590,827 shares were subject to stock options then outstanding under the 2016 Plan, approximately 894,550 shares were subject to stock options then outstanding under the 2006 Plan and approximately 4371,884,195 shares were subject to restricted stock and restricted stock unit awards then outstanding under the 2016 Plan. As noted above, no additional awards will be granted under the 2016 Plan if stockholders approve the 2024 Plan.
Shares issued in respect of any “full-value award” granted under the 2024 Plan will be counted against the Share Limit as 1.5 shares for every one share actually issued in connection with the award. For example, if the Company granted a bonus of 100 shares of its common stock under the 2024 Plan, 150 shares would be counted against the Share Limit with respect to that award. For this purpose, a “full-value award” generally means any award granted under the 2024 Plan other employees were expected to be eligible to participatethan a stock option or stock appreciation right.
Additional Share Limits.   The following other limits are also contained in the New ESPP.
Purchase Provisions
Each participant2024 Plan. These limits are in addition to, and not in lieu of, the Share Limit for the plan described above and, in the New ESPPcase of share-based limits, are applied on a one-for-one basis without applying the premium share-counting ratio for full-value awards discussed above.

The maximum number of shares that may authorize periodic payroll deductionsbe delivered pursuant to options qualified as incentive stock options granted under the plan is 4,000,000 shares. (For clarity, any shares issued in respect of incentive stock options granted under the plan will also count against the overall Share Limit above.)

The maximum number of shares subject to awards that mayare granted under the 2024 Plan during any one calendar year to any person who, on the grant date of the award, is a Non-Employee Director shall not exceed the lessernumber of (i) 10%shares that produce a grant date fair value for the award that, when combined with the grant date fair value of any other awards granted under the 2024 Plan during that same calendar year to that individual in his or her compensation,capacity as a Non-Employee Director, is $400,000, provided that this limit is $600,000 as to (1) a Non-Employee Director who is serving as the independent Chair of the Board of Directors or as a lead independent director at the time the applicable grant is made or (2) any new Non-Employee Director for the calendar year in which the non-employee director is definedfirst elected or appointed to the Board of Directors. For purposes of this limit, the “grant date fair value” of an award means the value of the award on the date of grant of the award determined using the equity award valuation principles applied in the New ESPPCompany’s financial reporting. This limit does not apply to, include his or her regular base salary in effect atand will be determined without taking into account, any award granted to an individual who, on the beginninggrant date of the offering period, exclusiveaward, is an officer or employee of the Company or one of its subsidiaries. This limit applies on an individual basis and not on an aggregate basis to all Non-Employee Directors as a group.

Share-Limit Counting Rules.   The Share Limit of the 2024 Plan is subject to the following rules:

Shares that are subject to or underlie awards which expire or for any paymentsreason are cancelled or terminated, are forfeited, fail to vest, or for overtime, bonuses, annualany other reason are not paid or delivered under the 2024 Plan will not be counted against the Share Limit and will again be available for subsequent awards other incentive payments, reimbursementsunder the 2024 Plan.

To the extent that shares are delivered pursuant to the exercise of expense allowances, fringe benefits (casha stock appreciation right granted under the 2024 Plan, the total number of underlying shares subject to the Award shall be counted against the Share Limit. (For purposes of clarity, if a stock appreciation right relates to 100,000 shares and is exercised at a time when the payment due to the participant is 15,000 shares, 100,000 shares shall be charged against the Share Limit with respect to such exercise.)

Shares that are exchanged by a participant or non-cash), moving expenses, deferred compensation, or contributions (other than contributions under a 401(k) or cafeteria plan) and (ii) such lesser amount determinedwithheld by the Company as full or partial payment in connection with any award granted under the 2024 Plan, Administrator per offering period. Aas well as any shares exchanged by a participant may increase or reduce hiswithheld by the Company to satisfy the tax withholding obligations related to any award granted under the 2024 Plan, will be counted against the Share Limit and will not again be available for subsequent awards under the 2024 Plan.

To the extent that an award is settled in cash or her ratea form other than shares, the shares that would have been delivered had there been no such cash or other settlement will not be counted against the Share Limit and will again be available for subsequent awards under the 2024 Plan.

In the event that shares are delivered in respect of payroll deductions during an offering period.
Ona dividend equivalent right, the last dayactual number of each offering period, the accumulated payroll deductions of each participant are automatically appliedshares delivered with respect to the purchaseaward shall be counted against the Share Limit. (For purposes of clarity, if 1,000 dividend equivalent rights are granted and outstanding when the Company pays a dividend, and 50 shares are delivered in payment of those rights with respect to that dividend, 75 shares shall be counted against the Share Limit after giving effect to the “full value award” counting ratio.)
In addition, the 2024 Plan generally provides that shares issued in connection with awards that are granted by or become obligations of the Company through the assumption of awards (or in substitution for awards) in connection with an acquisition of another company will not count against the shares available for issuance under the 2024 Plan. The Company may not increase the applicable share limits of the 2024 Plan by repurchasing shares of common stock on the market (by using cash received through the exercise of stock options or otherwise).
Types of Awards.   The 2024 Plan authorizes stock options, stock appreciation rights, and other forms of awards granted or denominated in the Company’s common stock or units of the Company’s common stock, as well as cash bonus awards. The 2024 Plan retains flexibility to offer competitive incentives and to tailor benefits to specific needs and circumstances. Any award may be structured to be paid or settled in cash.
A stock option is the right to purchase shares of the Company’s common stock at the purchase price in effect for that period.
Purchase Price
The purchasea future date at a specified price per share at which common stock is purchased on the participant’s behalf for each offering period is equal to 85% of the fair market value(the “exercise price”). The per share of the common stock on the last day of the offering period.
Valuation
The fair market value of the common stock on a given date is the closing salesexercise price of the common stock on the Nasdaq Global Select Market as of such date. As of March 15, 2022,an option generally may not be less than the fair market value of a share of the Company’s common stock as reported on the Nasdaq Stock Market was $7.17.
Special Limitations

An option may either be an incentive stock option or a participant’s rightnonqualified stock option. Incentive stock option benefits are taxed differently from nonqualified stock options, as described under “Federal Income Tax Consequences of Awards Under the 2024 Plan” below. Incentive stock options are also subject to acquire commonmore restrictive terms and are limited in amount by the U.S. Internal Revenue Code and the 2024 Plan.

Any awards under the 2024 Plan (including awards of stock options and stock appreciation rights) may be fully-vested at grant or may be subject to time- and/or performance-based vesting requirements.
Dividend Equivalents; Deferrals.   The Administrator may provide for the deferred payment of awards, and may determine the other terms applicable to deferrals. The Administrator may provide that awards under the 2024 Plan (other than options or stock appreciation rights), and/or deferrals, earn dividends or dividend equivalents based on the amount of dividends paid on outstanding shares of Common Stock, provided that any dividends and/or dividend equivalents as to the portion of an award that is subject to unsatisfied vesting requirements will be subject to termination and forfeiture to the same extent as the corresponding portion of the award to which they relate in the event the applicable vesting requirements are not satisfied (or, in the case of a restricted stock or similar award where the dividend must be paid as a matter of law, the dividend payment will be subject to forfeiture or repayment, as the case may be, if the related vesting conditions are not satisfied).
Assumption and Termination of Purchase Rights

A participant may withdraw from an offering period by giving advance notice priorCompany does not survive (or does not survive as a public company in respect of its common stock), including, without limitation, a dissolution, merger, combination, consolidation, conversion, exchange of securities, or other reorganization, or a sale of all or substantially all of the business, stock or assets of the Company, awards then-outstanding under the 2024 Plan will not automatically become fully vested pursuant to the endprovisions of the 2024 Plan so long as such awards are assumed, substituted for or otherwise continued. However, if awards then-outstanding under the 2024 Plan are to be terminated in such circumstances (without being assumed or substituted for), such awards would generally become fully vested (with any performance goals applicable to the award being deemed met at the “target” performance level), subject to any exceptions that period and his or her accumulated payrollthe Administrator may provide for in an applicable award agreement. The Administrator also has the discretion to establish other change in control provisions with respect to awards granted under the 2024 Plan. For example, the Administrator could provide for the offering periodacceleration of vesting or payment of an award in which withdrawal occurs shall be refunded.connection with a corporate event or in connection with a termination of the award holder’s employment. For the treatment of outstanding equity awards held by the named executive officers in connection with a termination of employment and/or a change in control of the Company, please see the “Potential Payments Upon Change in Control and Termination” below in this Proxy Statement.
Assignability
No purchase right will be assignable orTransfer Restrictions.   Subject to certain exceptions contained in Section 5.6 of the 2024 Plan, awards under the 2024 Plan generally are not transferable (otherby the recipient other than by will or the laws of descent and distribution)distribution and will beare generally exercisable, during the recipient’s lifetime, only by the participant.recipient. Any amounts payable or shares issuable pursuant to an award generally will be paid only to the recipient or the recipient’s beneficiary or representative. The Administrator has discretion, however, to establish written conditions and procedures for the transfer of awards to other persons or entities, provided that such transfers comply with applicable federal and state securities laws and are not made for value (other than nominal consideration, settlement of marital property rights, or for interests in an entity in which more than 50% of the voting securities are held by the award recipient or by the recipient’s family members).
Corporate Transaction
InAdjustments.   As is customary in incentive plans of this nature, each share limit and the number and kind of shares available under the 2024 Plan and any outstanding awards, as well as the exercise or purchase prices of awards, and performance targets under certain types of performance-based awards, are subject to adjustment in the event of certain reorganizations, mergers, combinations, recapitalizations, stock splits, stock dividends, or other similar events that change the proposed dissolutionnumber or liquidationkind of shares outstanding, and extraordinary dividends or distributions of property to the stockholders.
No Limit on Other Authority.   Except as expressly provided with respect to the termination of the Company,authority to grant new awards under the then-current offering period will terminate immediately prior to2016 Plan if stockholders approve the consummation of such dissolution or liquidation, unless otherwise provided by2024 Plan, the 2024 Plan Administrator.

U.S. Federal Income Tax Consequences of Awards under the 2024 Plan
Following is a general summaryThe U.S. federal income tax consequences of the 2024 Plan under current federal incomelaw, which is subject to change, are summarized in the following discussion of the general tax principles applicable to the New ESPP. The following2024 Plan. This summary is not intended to be exhaustive and, among other considerations, does not

describe the deferred compensation provisions of Section 409A of the U.S. Internal Revenue Code to the extent an award is subject to and does not satisfy those rules, nor does it describe state, local, or international tax consequences.
The New ESPP is intendedWith respect to qualify as an “employeenonqualified stock purchase plan” under Section 423 ofoptions, the Code. Participant contributions to the New ESPP are made on an after-tax basis. That is, a participant’s New ESPP contributions are deducted from compensation that is taxable to the participant and for which the Companycompany is generally entitled to a tax deduction.
Generally, no taxable income is recognized by a participant with respect to either the grant or exercise of his or her New ESPP option. The Company will have no tax deduction with respect to either of those events. A participant will generally recognize income (or loss) only upon a sale or disposition of any shares thatdeduct and the participant acquires under the New ESPP (including upon a deemed sale upon the death of a participant). The particular tax consequences of a sale of shares acquired under the New ESPP depend on whether the participant has held the shares for a “Required Holding Period” before selling or disposing of the shares. The Required Holding Period starts on the date that the participant acquires the shares under the New ESPP and ends on the later of (1) two years after the grant date of the offering period in which the participant acquired the shares, or (2) one year after the purchase date on which the participant acquired the shares.
If the participant holds the shares for the Required Holding Period and then sells the shares at a price in excess of the purchase price paid for the shares, the gain on the sale of the shares will be taxed as ordinary income to the participant to the extent of the lesser of (1) the amount by which the fair market value of the shares on the grant date of the offering period in which the participant acquired the shares exceeded the purchase price of the shares, or (2) the gain on the sale of the shares. Any portion of the participant’s gain on the sale of the shares not taxed as ordinary income will be taxed as long-term capital gain. If the participant holds the shares for the Required Holding Period and then sells the shares at a price less than the purchase price paid for the shares, the loss on the sale will be treated as a long-term capital loss to the participant. The Company will not be entitled to a tax deduction with respect to any shares held by the participant for the Required Holding Period, regardless of whether the shares are eventually sold at a gain or a loss.
The participant has a “Disqualifying Disposition” if the participant disposes of the shares before the participant has held the shares for the Required Holding Period. If the participant sells the shares in a Disqualifying Disposition, the participant will realize ordinaryrecognizes taxable income in an amount equal to the difference between the purchaseoption exercise price paid for the shares and the fair market value of the shares onat the purchase date on whichtime of exercise. With respect to incentive stock options, the participant acquired the shares, and the Companycompany is generally will benot entitled to a corresponding tax deduction. In addition, ifdeduction nor does the participant makesrecognize income at the time of exercise, although the participant may be subject to the U.S. federal alternative minimum tax.
The current federal income tax consequences of other awards authorized under the 2024 Plan generally follow certain basic patterns: nontransferable restricted stock subject to a Disqualifying Dispositionsubstantial risk of forfeiture results in income recognition equal to the shares at a price in excess of the fair market value over the price paid (if any) only at the time the restrictions lapse (unless the recipient elects to accelerate recognition as of the date of grant); bonuses, stock appreciation rights, cash and stock-based performance awards, dividend equivalents, stock units, and other types of awards are generally subject to tax at the time of payment; and compensation otherwise effectively deferred is taxed when paid. In each of the foregoing cases, the company will generally have a corresponding deduction at the time the participant recognizes income.
If an award is accelerated under the 2024 Plan in connection with a “change in control” ​(as this term is used under the U.S. Internal Revenue Code), the company may not be permitted to deduct the portion of the compensation attributable to the acceleration (“parachute payments”) if it exceeds certain threshold limits under the U.S. Internal Revenue Code (and certain related excise taxes may be triggered). Furthermore, under Section 162(m) of the Code, the aggregate compensation in excess of $1,000,000 payable to current or former Named Executive Officers (including amounts attributable to equity-based and other incentive awards) may not be deductible by the Company in certain circumstances.
Specific Benefits under the 2024 Performance Incentive Plan
The Company has not approved any awards that are conditioned upon stockholder approval of the 2024 Plan. The Company is not currently considering any other specific award grants under the 2024 Plan, other than the annual grants of stock options and restricted stock units to our Non-Employee Directors described in this Proxy Statement. If the 2024 Plan had been in existence in fiscal 2023, the Company expects that its award grants for fiscal 2023 would not have been substantially different from those actually made in that year under the 2016 Plan. For information regarding stock-based awards granted to the Company’s named executive officers and Non-Employee Directors during fiscal 2023, see the material under the heading “Executive Compensation” and “Director Compensation” below.
The following paragraphs include additional information to help you assess the potential dilutive impact of the Company’s equity awards and the 2024 Plan.
The Company’s Employee Stock Purchase Plan generally provides for broad-based participation by employees of the Company (and certain of its subsidiaries) and affords employees who elect to participate

an opportunity to purchase shares of the Company’s common stock at a discount.

“Overhang” refers to the number of shares of the Company’s common stock that are subject to outstanding awards or remain available for new award grants. The following table shows the total number of shares of the Company’s common stock that were subject to outstanding restricted stock and restricted stock unit awards granted under the 2016 Plan, that were subject to outstanding stock options granted under the 2016 Plan or the 2006 Plan and that were then available for new award grants under the 2016 Plan as of December 31, 2023 and as of March 15, 2024. (In this 2024 Plan proposal, the number of shares of the Company’s common stock subject to restricted stock and restricted stock unit awards granted during any particular period or outstanding on any particular date is presented based on the actual number of shares of the Company’s common stock covered by those awards and before applying the provisions of the 2016 Plan for counting these awards against the plan’s share limit as 1.5 for every share actually issued pursuant to the award. For awards subject to performance-based vesting requirements, the number of shares presented is based on the maximum level of performance.)

4,733,850 shares in 2024 through March 15, 2024 (which was 2.12% of the number of shares of the Company’s common stock issued and outstanding on March 15, 2024), of which 1,748,000 shares were subject to restricted stock and restricted stock unit awards (excluding performance-based vesting awards), and 2,985,850 shares were subject to stock options (excluding performance-based vesting options).
Thus, the total number of shares of the Company’s common stock subject to awards granted under the 2016 Plan per year over the last three fiscal years (2021, 2022 and 2023) has been, on average, 2.53% of the weighted-average number of shares of the Company’s common stock issued and outstanding for the corresponding year, and this percentage is consistent with the Company’s 2024 awards under the 2016 Plan through March 15, 2024 (which, as noted above, cover 2.12% of the number of shares of the Company’s common stock issued and outstanding shares on March 15, 2024. Performance-based vesting awards have been included above in the purchase date,year in which the participant will realize capital gainaward was granted. The actual number of shares subject to performance-based stock options that became eligible to vest each year because the applicable performance-based condition was satisfied in an amount equalthat year (subject to the difference betweensatisfaction of any applicable time-based vesting requirements) was as follows: zero in 2021, 410,000 in 2022, zero in 2023, and zero to date (as of March 15, 2024) in 2024.
The total number of shares of our common stock that were subject to awards granted under the selling price2016 Plan, the 2006 Plan and the 2002 Plan that terminated or expired, and thus became available for new award grants under the 2016 Plan, in each of the shareslast three fiscal years, and to date (as of March 15, 2024) in 2024, are as follows: 1,323,796 in 2021, 2,071,522 in 2022, 569,096 in 2023, and 315,098 in 2024. Shares subject to 2016 Plan, the 2006 Plan and the fair market2002 Plan awards that terminated or expired and became available for new award grants under the 2016 Plan have been included when information is presented in this 2024 Plan proposal on the number of shares available for new award grants under the 2016 Plan.
The Compensation Committee anticipates that the 4,000,000 additional shares requested for the 2024 Plan (together with the shares available for new award grants under the 2016 Plan on the Annual Meeting date and assuming usual levels of shares becoming available for new awards as a result of forfeitures of outstanding awards) will provide the Company with flexibility to continue to grant equity awards under the 2024 Plan through approximately the end of 2025 (reserving sufficient shares to cover potential payment of performance-based awards at maximum payment levels). However, this is only an estimate, in the Company’s judgment, based on current circumstances. The total number of shares that are subject to the Company’s award grants in any one year or from year-to-year may change based on a number of variables,

24


including, without limitation, the value of the Company’s common stock (since higher stock prices generally require that fewer shares on the purchase date. Alternatively, if the participant makes a Disqualifying Dispositionbe issued to produce awards of the shares atsame grant date fair value), changes in competitors’ compensation practices or changes in compensation practices in the market generally, changes in the number of employees, changes in the number of directors and officers, whether and the extent to which vesting conditions applicable to equity-based awards are satisfied, acquisition activity and the need to grant awards to new employees in connection with acquisitions, the need to attract, retain and incentivize key talent, the type of awards the Company grants, and how the Company chooses to balance total compensation between cash and equity-based awards.
The closing market price for a price less than the fair market valueshare of the shares on the purchase date, the participant will realize a capital loss in an amount equal to the difference between the fair market valueCompany’s common stock as of March 15, 2024 was $2.52 per share.

Board Leadership Structure
The Board has determined that our current structure of separating the roles of Chairman of the Board and Chief Executive Officer is in the best interests of the Company and our stockholders. Mr. Scully has served as Chairman of the Board since January 2018; and Mr. Littlefair has been the Chief Executive Officer of the Company since June 2001. As Chairman of the Board, Mr. Scully focuses on organizing Board activities to enable the Board to effectively provide guidance to and oversight (including risk oversight) and accountability of management. The Chairman of the Board, among other things, creates and maintains an effective working relationship with the Chief Executive Officer and other members of management and with the other members of the Board, provides the Chief Executive Officer ongoing direction regarding Board needs, interests and opinions, and ensures the Board agenda is appropriately directed toward matters significant to the Company. Separating the roles of Chairman of the Board and Chief Executive Officer allows Mr. Littlefair, as Chief Executive Officer, to focus on managing the day-to-day direction and implementing the long-term strategic goals of the Company.
The functions of the Board are carried out by the full Board and, when delegated, by the Board’s committees. Each director is a full and equal participant in the major strategic and policy decisions of our Company.
Board Role in Risk Oversight
Risk is inherent in every business. We face a number of risks, including business, operational, strategic, competitive, financial, political, legislative, environmental, safety and regulatory risks, as well as risks related to compensation, cybersecurity threats or incidents, capital expenditures, derivative transactions, commodity-based exposures, acquisitions or other strategic transactions and financing and other liquidity matters. In general, our management is responsible for the day-to-day management of the risks we face, while our Board, as a whole and through its committees, is responsible for the oversight of risk management.
In its risk oversight role, the Board and each of its committees regularly review and discuss, internally and with management, the material short-, intermediate-, and long-term risks confronting our business,

28


based on reports prepared and delivered by management and outside advisors that address these risks and other information deemed relevant. The Board also monitors our risk management and corporate governance policies, including the day-to-day risk management processes designed and implemented by management, and generally evaluates how management operates our Company with respect to risk exposures. These risks and risk management policies are also reviewed and

24


analyzed in depth by the Board at an annual strategic planning session with members of senior management. Due to the dynamic nature of risk and the business environment generally, management regularly updates the Board on key enterprise risks. Board and committee agendas and meeting materials are updated throughout the year so that emerging enterprise risks may be reviewed and discussed at the relevant times. This process facilitates the Board’s ability to fulfill its oversight responsibilities of the Company’s risks in a timely and effective manner. The Board considers the risks and vulnerabilities we face when granting authority to management and approving business strategies and particular transactions. Additionally, the full Board oversees our initiatives and risk management activities relating to sustainability, diversity, equity and inclusion.
The Board performs its risk oversight function in part through its committees, which are comprised solely of independent directors. Each Board committee’s risk oversight role is as follows:


The audit committee oversees management of risks related to our financial reporting, disclosure processes and accounting policies, and information technology and cybersecurity, as well as any related party or conflict-of-interest transactions;


The compensation committee oversees management of risks related to our compensation practices and policies; and


The nominating and corporate governance committee oversees management of risks related to Board processes and composition, including director independence, and corporate governance matters.
Information Security
Our Chief Operating Officer oversees cybersecurity and other information technology risks affecting the Company and reports on the same to the Board at least quarterly. Our Audit Committee formally oversees information security, including cybersecurity risks, and receives regular updates from management. We use a combination of internal security technology solutions, paired with strategic external partnerships to mitigate cybersecurity threats to the Company. We leverage the cybersecurity framework of our security managed service provider and have implemented a training and compliance cybersecurity program. We have, and will continue to, use third party security firms to perform simulated cyber-attacks on our environment to identify exploitable vulnerabilities. We use these results to harden our security posture with our security managed service provider. Our information technology infrastructure is externally audited as part of our Sarbanes Oxley audit process and our controls include information security standards. We maintain standalone cybersecurity insurance and believe we are adequately insured against losses related to a potential information security breach. We have not experienced a material breach in information security.
Code of Ethics
We have adopted a written code of ethics applicable to our directors, officers and other employees, including our principal executive, financial and accounting officers and controller or persons performing similar functions. This code of ethics establishes policies to promote honest and ethical conduct and is designed to comply with applicable Nasdaq and SEC rules. The nominating and corporate governance committee reviews our code of ethics periodically and may propose or adopt additions or amendments that it determines are required or appropriate.
Our code of ethics is accessible on our website at

http://investors.cleanenergyfuels.com/corporate-governance
. We expect that any amendments to or waivers from certain provisions of our code of ethics applicable to any principal executive, financial or accounting officer or controller or persons performing similar functions will be disclosed on our website to the extent required by applicable Nasdaq or SEC rules.
Corporate Governance Guidelines
We have adopted written corporate governance guidelines that set forth standards for director qualifications and responsibilities, Board committees, Board leadership structure, director compensation, director orientation and continuing education, Chief Executive Officer evaluation and management succession, Board self-evaluations, Board oversight of the Company’s strategic planning, and director and officer stock ownership, among other things. The nominating and corporate governance committee reviews our corporate governance guidelines periodically and may from time to time propose or adopt additions or amendments it determines are required or appropriate. Our corporate governance guidelines are accessible on our website at http://investors.cleanenergyfuels.com/corporate-governance.

25


Board Evaluations
At least annually, our nominating and corporate governance committee leads an evaluation of each of our directors and our Board as a whole and each of its committees. As part of this evaluation, the Board considers the areas in which the Board believes it could improve. Each of our committees also conducts an evaluation of itself at least annually.

29


Board Diversity Matrix (as of April 4, 2024)
While our Board has no formal policy for the consideration of diversity in identifying director nominees, the nominating and corporate governance committee seeks to have a board of directors that will reflect a balance of experience, qualifications, diversity, attributes and skills desirable for the Board as a whole. To achieve this, the nominating and corporate governance committee considers individuals from various disciplines and backgrounds in recommending director nominees to the Board, including diversity characteristics that may be self-identified by directors or director nominees, such as race, gender, military service, or other socioeconomic or demographic characteristics.

Chief Executive Officer Evaluation and Management Succession
Our Board works with our nominating and corporate governance committee to evaluate potential successors to our Chief Executive Officer and to ensure that a CEOChief Executive Officer succession plan is in place. Our Chief Executive Officer also makes available his recommendations and evaluations of potential successors, as well as reviews any development plans recommended for such individuals.
Director Stock Ownership Guidelines
We believe it is important to encourage our directors to hold a material amount of our common stock, which links their long-term economic interest directly to that of our stockholders. To achieve this goal, we have established stock ownership guidelines applicable to our directors. These guidelines provide that each non-employee director is required to own shares of our common stock valued at $180,000 or more by the later of December 14, 2019 and five years after the date of a director’s initial election to the Board. Stock options are not counted toward satisfaction of these stock ownership requirements. Directors who attain this stock ownership level by the stated deadline will continue to satisfy the stock ownership requirements if the value of their stock holdings declines after such deadline solely due to a decrease in the trading price of our common stock. All of our non-employee directors, with the exception of Mses. Boissy-Rousseau and Paskett and Mr. Wolffsheim, had satisfied these stock ownership guidelines as of the record date for the Annual Meeting. Ms. Paskett, who was appointed to the Board in December 2021, is still within the five-year grace period to comply with the stock ownership guidelines. In addition, the Board has determined that the director stock ownership guidelines do not apply to Ms. Boissy-Rousseau or Mr. Wolffsheim for so long as each is designated by TMS to serve as a director and waives his or her right to receive compensation for serving on the Board. See the descriptions under “Proposal 1: Election of Directors — General” and “Director Compensation” for more information.
We have also established stock ownership guidelines applicable to certain of our executive officers, which are described under “Compensation Disclosure and Analysis — Executive Stock Ownership Guidelines” below.
Stockholder Communications with the Board
We have adopted a formal process by which stockholders and interested parties may communicate with our Board, which is accessible on our website at
http:
https://investors.cleanenergyfuels.com/corporate-governance/contact-the-board
. This centralized process assists the Board in reviewing and responding to communications from stockholders and other interested parties in an appropriate manner. Communications to the Board must be in writing and mailed to our Corporate Secretary at the address of our principal executive offices. The communication can be addressed to one or more individual directors or to the Board as a group, and the name of any specific intended recipient(s) should be noted in the communication. Communications submitted by postal mail may be anonymous. The Corporate Secretary typically reviews all such communications and will forward them to the Board or any identified individual director(s), unless any such communication is deemed to be, in the Corporate Secretary’s discretion, unrelated to the duties and responsibilities of the Board or unduly hostile, threatening, illegal or similarly unsuitable for Board consideration.
Director Nomination Process
Our Board, as a whole and through our nominating and corporate governance committee, is responsible for identifying, evaluating and recommending nominees to serve as directors of our Company.

30


Identifying and Evaluating Director Nominees
Our nominating and corporate governance committee is responsible for identifying individuals qualified to become members of the Board and recommending these candidates to our Board for nomination

26


or appointment. Our nominating and corporate governance committee may utilize a variety of methods to identify potential director candidates. For example, candidates may come to the attention of the nominating and corporate governance committee through current members of the Board, executive officers, professional search firms, stockholders or others. These candidates may be evaluated and considered by our nominating and corporate governance committee at any point during the year, including in connection with each annual meeting of our stockholders. For each such annual meeting, the nominating and corporate governance committee recommends to our Board certain director nominees to stand for election at the annual meeting based on the committee’s evaluation of all potential director candidates, including incumbent directors. The Board then selects its director nominees based on its determination, relying on the recommendation of and other information provided by the nominating and corporate governance committee as it deems appropriate, of the suitability of each potential director candidate to serve as a director of our Company.
Stockholder Recommendations of Director Candidates
In accordance with its charter, our nominating and corporate governance committee is responsible for considering and evaluating properly submitted stockholder recommendations of candidates for Board membership. Any such recommendation of director candidates for nomination by the Board in connection with our next annual meeting of stockholders should be made in writing by January 1st of the applicable year and delivered or mailed to our Corporate Secretary at the address of our principal executive offices, and should include the name, address and a current resume of the proposed director candidate, a statement describing the candidate’s qualifications and consent to serve on our Board if selected as a director nominee, and contact information for personal and professional references. The submission should also include the name and address of the stockholder who is submitting the proposed director candidate, the number of shares of our common stock that are owned of record or beneficially by the submitting stockholder and a description of all arrangements or understandings between the submitting stockholder and the proposed director candidate. We may also request that any proposed director candidate and any stockholder proposing a director candidate furnish us with such other information as may reasonably be required for our nominating and corporate governance committee to determine the eligibility of such proposed director candidate to serve as a director of our Company.
All properly submitted stockholder recommendations will be aggregated together and with any other director candidates proposed by other sources, for consideration and evaluation by our nominating and corporate governance committee and will receive the same consideration by our nominating and corporate governance committee as is received by any other director candidate. In evaluating all director candidates, the nominating and corporate governance committee will consider, among other things, the director qualifications set forth in our corporate governance guidelines, as described in “Proposal 1: Election of Directors” above. Any stockholder-recommended director candidate that is selected by our nominating and corporate governance committee would be recommended by the committee as a director nominee to the Board, which would then consider and evaluate the candidate in the same manner and based on the same criteria and qualifications as other prospective director candidates. If approved by the Board, the stockholder-recommended candidate would be appointed as a director to a vacant seat on the Board or included in the Board’s slate of director nominees to stand for election at our next annual meeting of stockholders.
SustainabilityStockholder Nominations of Directors

In accordance with these requirements, any stockholder nomination of a director must be made in writing and delivered to or mailed and received by our Corporate Secretary at the third quarter of 2020, Clean Energy worked with Business for Social Responsibility (BSR) to develop a robust and ambitious sustainability strategy. To do so, a materiality assessment was conducted that helped us determine which environmental, social and governance (“ESG”) issues have the greatest impact on our business success and where we have the most impact on stakeholders. The resultant list of key material issues from the assessment was used to form the foundationaddress of our sustainability vision, strategy and goals,principal executive offices within a specified time period before the annual meeting of stockholders at which Clean Energy looksthe director nominee is to continue building upon as new emerging issues come to light.

In alignment with global environmental, social and governance reporting, we recognize the importance of maintaining a diverse and inclusive workforce and supplier basesustainability report that is reflectiveposted on our website at www.cleanenergyfuels.com, which highlights the efforts of different teams across the communities in which we operate. We acknowledge the lack of diversity in the energy sectororganization and strive to be part of the solution. The safety of our employees and contractors is also a top priority, and we strive to be a zero-incident workplace for our service technicians and staff, as well as our customers using our facilities.
Advancing Smart Policies that Drive the Transformation to Renewable Fuels:   Enacting systemic change across all industries will be necessary to achieve our collective climate goals. We recognize that the effects of

climate change are already impacting the Earth today, and that the transition to a low-carbon economy is likely to bring new risks to businesses that do not adapt. We also recognize that conventional natural gas extraction and processing causes environmental and social impacts that must be appropriately and equitably managed. By investing in the green energy transition, we reduce our own risks and provide long lasting benefits to society. To enable lasting change, we must ensure the adoption of performance-driven state and federal policies that accelerate the shift to renewable zero or negative carbon intensity fuels in a way that does not place an undue burden on small businesses or underrepresented communities. Clean Energy is also committed to contributing to economic development in communities where we conduct business by hiring local suppliers whenever possible.

COMPENSATION DISCUSSION AND ANALYSIS
Overview
This compensation discussion and analysis describes the material features of the compensation awarded to, earned by, or paid to each person who served as our principal executive officer (Andrew J. Littlefair)Littlefair, our President and Chief Executive Officer) or principal financial officer (Robert M. Vreeland)Vreeland, our Chief Financial Officer) in 2021,2023, and the only two other individuals who were serving as executive officers at the end of 20212023 or at any time during the 20212023 calendar year (Mitchell W. Pratt, who served in an executive officer role as Chief Operating Officer and Corporate Secretary until May 2023 and then transitioned to a non-executive officer role, and Barclay F. Corbus)Corbus, our Senior Vice President, Strategic Development and Head of Renewable Fuels). Messrs. Littlefair, Vreeland, Pratt and Corbus are collectively referred to in this proxy statement as our “named executive officers.” This analysis also discusses our compensation philosophy and objectives, the methodologies used for establishing the compensation programs for the named executive officers, and the policies and practices for administering such programs.
Business
We are a leading renewable energy company focused on the procurement and distribution of renewable natural gas (“RNG”) and conventional natural gas, in the form of compressed natural gas (“CNG”) and liquefied natural gas (“LNG”), for the United States (“U.S.”) and Canadian transportation markets. RNG, which is delivered as either CNG or LNG, is created by the recovery and processing of naturally occurring, environmentally detrimental waste methane (“biogas”) from non-fossil fuel sources — such as dairy and other livestock waste and landfills — for beneficial use as a replacement for fossil-based transportation fuels. Methane is one of the most potent climate-harming greenhouse gases (“GHG”) with a comparative impact on global warming that is about 25 times more powerful than that of carbon dioxide. We are focused on developing, owning, and operating dairy and other livestock waste RNG projects and supplying RNG to our customers in the heavy and medium-duty commercial transportation sectors. We have participated in the alternative vehicle fuels industry for over 20 years. We believe we are in a unique position because valuable Environmental Credits (as defined below) are generated by the party that dispenses RNG into vehicle fuel tanks, and we believe we have access to more dispensers than any other market participant.
We believe we were the first organization to supply RNG for vehicle fuel use in the U.S., and sales of our RNG for such purpose have increased from 13.0 million gasoline gallon equivalents (“GGEs”) in 2013 to 225.7 million GGEs in 2023. We calculate one GGE to equal 125,000 British Thermal Units (“BTUs”) and, as such, one million BTUs (“MMBTU”) equals eight GGEs. We are North America’s leading provider of the cleanest fuel for the commercial transportation market, based on both the number of stations operatedwe operate and the amount of gasoline gallon equivalents (“GGEs”)GGEs sold of RNG, CNG and conventional natural gas delivered. Through our salesLNG, which amounted to a total of RNG, which is derived from biogenic methane produced by the breakdown of organic waste, we help thousands of vehicles, from airport shuttles to city buses to waste and heavy-duty trucks, to reduce their amount of climate-harming greenhouse gas, while also reducing criteria pollutants such as Oxides of Nitrogen, or NOx. RNG is delivered as compressed natural gas (“CNG”) and liquefied natural gas (“LNG”). Our sales of RNG have increased dramatically, from 13.0466.2 million GGEs in 2013 (the year we introduced2023. With the Company’s focus on RNG, to the vehicle fuel market) to 167.0 million GGEs in 2021. The Company’sour sales of RNG have grown from 12% of our vehicle fuel sales in 2013 to 78%89% of our vehicle fuel sales in 2021.2023 (excluding GGEs from O&M (as defined below) services sales and non-vehicle sales). We believe that during 20212023 we provided 58%53% and 47% of the RNG used for transportation fuel in California and the United States,U.S., respectively. Our business uniquely benefits from the U.S. federal, state and local government credits generated by selling RNG as a vehicle fuel (collectively, “Environmental Credits”), which are generated by the party that dispenses RNG into vehicle fuel tanks. We believe we have access to more dispensers than any other market participant.
As a comprehensive clean energy solutions provider, we supply RNG and conventional natural gas, in the form of CNG and LNG, for heavy and medium-duty vehicles;also design and build, as well as operate and maintain (“O&M”), public and private vehicle fueling stations;stations in the U.S. and Canada; sell and service compressors and other equipment used in RNG production and at fueling stations; transport and sell RNG and conventional natural gas via “virtual” natural gas pipelines and interconnects; sell Environmental CreditsU.S. federal, state and local government credits (collectively, “Environmental Credits”) we generate;generate by selling RNG as a vehicle fuel, including Renewable Identification Numbers (“RIN Credits” or “RINs”) under the federal Renewable Fuel Standard Phase 2 and credits under the California, Oregon, and Washington Low Carbon Fuel Standards (collectively, “LCFS Credits”); and obtain other federal, state and local tax credits, grants and incentives.
We serve fleet vehicle operators in a variety of markets, including heavy-duty trucking, airports, refuse, public transit, industrial and public transit.institutional energy users, and government fleets. We believe these fleet markets will continue to present a growth opportunity for our vehicle fuels for the foreseeable future. As of December 31, 2021, we deliver RNG to the transportation market through 548 fueling stations we own, operate or supply in 42 states and the District of Columbia in the U.S., including over 200 stations in California

Key 2021-20222023 Pay Decisions
Key pay decisions for 2021 and 20222023 include the following:


Base salaries:   For 20212023, the compensation committee maintainedapproved no salary increase for Mr. Littlefair’sLittlefair (whose salary had not been adjusted since he elected to take a voluntary pay reduction in February 2015); a 3.5% salary increase for Mr. Vreeland; a 1% salary increase for Mr. Pratt; and a 4.4% salary increase for Mr. Corbus. On May 17, 2023, Mr. Pratt executed an amended and restated employment agreement which included an incremental 5.5% increase over his 2022 base salary atlevel in connection with his 2020 level (it has been at the same level since 2015) and increased the base salaries of Messrs. Vreeland, Pratt and Corbus by 13%, 8% and 8%, respectively.transition to Chief Technology Development Officer.


Performance-based cash bonuses:   Based on our performance results achieved for 2021,2023, the compensation committee awarded cash incentives under our 20212023 performance-based cash incentive plan to our named executive officers abovebelow each executive’s target incentive.


Equity awards:   In the first quarter of 2021,2023 the compensation committee granted RSUs andequity awards in the form of stock options to our named executive officers, in accordance with our regular grants of long-term incentives to employees.

In December of 2021, the compensation committee introduced two new types of performance-based stock option awards that were granted to the named executive officers as additional long-term

32


incentives. The first new performance-based option is structured to incentivize securing additional GGEs of RNG supply via investment to increase the volume of our RNG deliveries, and the vesting of 100% of each grant is subject to the Company’s attainment of RNG supply milestones. The second new performance-based option is structured to incentivize long-term appreciation in the value of our shares, and the vesting of 100% of each grant is subject to the Company’s attainment of a stock price representing a greater than 100% premium above the closing price of a share of common stock on the grant date. The compensation committee determined in December that the Company was at a critical juncture and that it was of primary importance to incentivize the named executive officers to (1) create long-term stockholder value by increasing the Company’s price per share and (2) strategically execute on expanding our RNG business over the long-term. The December grants represent the largest component of each named executive officer’s 2021 compensation and are intended to provide a meaningful performance-based equity incentive over a number of years going forward. Becausefirst quarter of the December grants, the compensation committee determined it will not grant any additionalcalendar year. No equity awards were granted to named executive officers in calendar 2022.2022, with the exception of 150 restricted stock units awarded to each of Messrs. Littlefair and Pratt, along with various other Company employees, on December 19, 2022 in recognition for over 20 years of service to the Company, and in 2023 we resumed our normal annual equity grant practices.
Introduced new performance-based option grants in December of 2021 to incentivize strategic investment in our RNG business and long-term share price appreciation. No additional equity awards will be made to named executive officers in calendar 2022.
Compensation Program Objectives and Philosophy
Our compensation committee oversees the design and administration of our executive compensation program. The primary objectives of our executive officer compensation program are to attract, retain and motivate talented and dedicated executive officers; to reward individual performance and achievement of key corporate objectives, including the objectives set forth in our annual strategic plan, without promoting excessive or unnecessary risk-taking; to align the interests of our executivesexecutive officers with those of our stockholders; and to provide compensation that we believe is fair in light of an executive’sexecutive officer’s experience, responsibilities, performance and tenure with our Company and in relation to the compensation provided to other executives of our Company and comparable executives at certain peer companies.
To achieve these objectives, we maintain an executive compensation program that includes the following components: base salary, cash incentives, equity incentives, change in control and post-termination severance compensation and other benefits. The compensation program also places a strong emphasis on pay-for-performance, as a significant portion of executive compensation must be earned through the annual cash bonus opportunity, and our equity incentives have high upside upon achieving share price appreciation. The compensation committee developed our executive compensation program by drawing on its experience and judgment in establishing programs it believes are appropriately rewarding and responsible for a growth company in a developing industry. The compensation committee reviews and evaluates our executive compensation program, including its objectives and the forms of compensation used to achieve these objectives, on at least an annual basis, and adjusts the program as it deems appropriate and considers factors relevant in establishing appropriate levels and mix of compensation for our executives.executive officers.
Process for Determining Executive Compensation
The Compensation Committee’s Role
The compensation committee’s general practice is to establish the annual compensation mix and levels for each of our executivesexecutive officers at the beginning of each fiscal year, typically in our first quarter in connection with annual performance reviews. Performing this process after the end of the prior year allows the compensation committee to incorporate into its analysis information on the Company’s and each individual’s performance during the prior year and to assess each executive’sexecutive officer’s overall contributions to the Company.
The compensation committee then compiles this information to establish annual base compensation and performance-related targets and to adjust long-term incentives as appropriate. However, as discussed above and below,In 2023, the compensation committee spent significant time in the third and fourth quarter of 2021 evaluating the structure of our long-term equity incentive awards, and in connection with the introduction of two new types of performance-based options, determined to grant the named executive officers their long-term incentive award in December of 2021. Because of the December grants, the compensation committee determined it will not grant any additional equity awards to named executive officers in calendar 2022.

Compensation Consultant
Our compensation committee hasreturned to granting equity awards in the authority to engage the servicesform of compensation consultants or other experts or advisors as it deems appropriate in fulfilling its responsibilities and has retained the services of Semler Brossy Consulting Group, LLC (“Semler Brossy”). The compensation committee has the sole authority to approve the terms of this engagement, and Semler Brossy reportsstock options to the compensation committee only under this engagement. Before engaging Semler Brossy, the compensation committee determined that Semler Brossy was independent and that its work would not raise any conflicts of interest after taking into consideration the factors set forth in applicable Nasdaq and SEC rules.
Compensation Consultant’s 2021 Review
In the third quarter of 2021, the compensation committee instructed Semler Brossy to complete a full review of the Company’s executive compensation program within the context of the competitive market, including comparing the Company’s executive compensation components and levels with a group of selected peer companies that is described in more detail below. The compensation committee consulted with Semler Brossy in connection with its introduction of two new types of performance-based options granted in December, 2021 for 2022 and beyond.
Peer Group
Selecting a group of our peer companies is challenging for many reasons, including principally our belief that we are the only publicly traded company, the primary line of business of which is to sell RNG, CNG and LNG for use as a vehicle fuel. In selecting our peer companies for compensation purposes, our compensation committee generally sought to identify companies that are similar to us across a number of metrics and that, in the compensation committee’s view, compete with us for talent.
In 2021, the compensation committee worked with Semler Brossy to review our peer group given our strategic shift to producing RNG in addition to our downstream distribution of natural gas.
Based on Semler Brossy’s recommendations, the compensation committee approved the following 23 companies as our peer companies for compensation purposes, which we refer to collectively as the “Peer Group.”
Aemetis, Inc.AeroVironment, Inc.Ameresco, Inc.
Ballard Power Systems, Inc.Battalion Oil CorporationBloom Energy Corporation
Broadwind, Inc.Callon Petroleum CompanyCovanta Holding Corporation
Darling Ingredients, Inc.Enphase Energy, Inc.FuelCell Energy, Inc.
Gevo, Inc.Green Plains, Inc.Montauk Renewables, Inc.
Northern Oil and Gas, Inc.Ormat Technologies, Inc.Plug Power, Inc.
Power Solutions International, Inc.Renewable Energy Group, Inc.Rice Acquisition Corp.
Westport Fuel Systems, Inc.W&T Offshore, Inc.
As of June 15, 2021 when the Peer Group was initially constructed, our 200-day average market capitalization was at the 57th percentile of the Peer Group companies, while our trailing twelve-month revenues and EBIT were at the 37th percentile and 51st percentile of the Peer Group companies, respectively.
The compensation committee believes benchmarking may not always be the most appropriate tool for setting compensation due to aspects of our business, objectives, and the way we’ve structured executive roles that may be unique to us. As a result, the compensation committee retains discretion to vary executive compensation components and levels.
For compensation decisions in 2021 and heading into 2022, the compensation committee did not tie named executive officer compensation (either specific elements of compensation or total compensation levels) to any predetermined benchmark but did continue to use the Peer Group data as one of several reference points when setting executive officer compensation levels through the exercise of its business judgment.

Review of Stockholder Say-on-Pay Votes
Consistent with the preference of our stockholders, which was expressed at our annual meeting of stockholders held in May 2018, our stockholders can cast an advisory vote on executive compensation, or a “say-on-pay” vote, once every year, and the next such vote will occur at the Annual Meeting. At the Company’s annual meeting of stockholders held in 2021, our executive compensation received a favorable advisory vote from approximately 95% of the votes cast on the proposal at the meeting (which excludes abstentions and broker non-votes).
We believe the high degree of support on our 2021 say-on-pay proposal, together with a similar high degree of support on our 2020 say-on-pay proposal, demonstrates that stockholders support our executive compensation program design.
We expect to actively engage with our stockholders to discuss various compensation and governance matters and consider their feedback in determining named executive officer compensation. The compensation committee will also continue to consider the outcome of the Company’s say-on-pay votes, as well as this direct stockholder input, when making future compensation decisions for our named executive officers and in respect of our compensation program generally.
Components of Compensation
Our named executive officers’ compensation consiststhe first quarter of the following components:calendar year.

Management’s Role
Base salary;

Performance-based annual cash incentives;

Equity incentives;

Change in control and post-termination severance compensation; and

Other benefits that are generally available to all of our salaried employees.
The following chart shows the mix of components of compensation for our named executive officers for 2021:
[MISSING IMAGE: tm223596d1-pc_compen4c.jpg]
The compensation committee views the various components of compensation as distinct methods of achieving the various objectives of our compensation program and, as a result, it generally does not believe significant compensation derived from one component should negate or reduce compensation from other components. The compensation committee does, however, review and evaluate each executive’s total compensation, and it may make decisions regarding levels of certain compensation components based on this evaluation of overall compensation, including, for instance, determinations regarding target levels under our performance-based cash incentive plan. The compensation committee also strives to provide an appropriate mix of long-term and short-term, cash and non-cash, and different forms of non-cash compensation; however, the compensation committee has not adopted formal plans or programs that allocate total compensation among these various characteristics.

35


In determining the mix and level of compensation components for our named executive officers, Mr. Littlefair, our President and Chief Executive Officer, typically makes recommendations to our compensation committee regarding appropriate pay. After reviewing Mr. Littlefair’s recommendations, our compensation committee makes the final determination regarding compensation mix and levels for each of our named executive officers. Although Mr. Littlefair submits recommendations to the compensation committee regarding his own proposed compensation, which the committee takes under advisement, Mr. Littlefair does not participate in the compensation committee’s deliberations regarding his own compensation. Additionally, the financial performance criteria of our annual incentive plan are prepared by our Chief Financial Officer based on our annual budget, and the strategic initiatives are developed by our Chief Executive Officer, with the plan design and targets ultimately being approved by the compensation committee.
Mr. Littlefair’s recommendations and the compensation committee’s decisions regarding the mix and level of compensation components for each of our named executive officers are based on a number of factors, including, among others, the individual’s performance and contribution to our strategic plan and other business objectives; the Company’s overall performance in light of business and industry conditions; general industry trends and market reference points; the level of the individual’s responsibility; the seniority of the individual; the individual’s long-term commitment to our Company; the available pool of individuals with similar skills; retention risk for the individual; principles of pay equity and relative pay (we generally believe that executives with comparable experience, levels of responsibility and performance deserve comparable compensation, and that more experienced executives with a greater degree of responsibility and higher performance levels deserve higher levels of compensation on a relative basis); the role of each compensation component in achieving the objectives of our executive compensation program; and the compensation committee’s business judgment and experience.
Compensation Consultant
Our compensation committee has the authority to engage the services of compensation consultants or other experts or advisors as it deems appropriate in fulfilling its responsibilities and has retained the services of Semler Brossy. The compensation committee has the sole authority to approve the terms of this engagement, and Semler Brossy reports to the compensation committee only under this engagement and does not provide any additional services to us other than its work for the compensation committee. Before engaging Semler Brossy, the compensation committee determined that Semler Brossy was independent and that its work would not raise any conflicts of interest after taking into consideration the factors set forth in applicable Nasdaq and SEC rules. In 2023, Semler Brossy assisted as part of the engagement and supported the compensation committee in determining our Board of Director pay levels and compensation plan, reviewing our peer group for 2024 compensation actions, analyzing our equity pool usage, providing executive pay benchmarking to help inform 2024 compensation decisions for the executive team, and supported on various other ad hoc and governance-related items.
Peer Group
Selecting a group of our peer companies is challenging for many reasons, including principally our belief that there are few publicly traded companies in our line of business. In selecting our peer companies for compensation purposes, our compensation committee generally sought to identify companies that are similar to us across a number of metrics and that, in the compensation committee’s view, compete with us for talent.
In 2022, based on Semler Brossy’s recommendations, the compensation committee approved the following 21 companies as our peer companies that were used for 2023 for compensation purposes, which we refer to collectively as the “2023 Peer Group.” When the compensation committee performed an analysis to determine which companies to include in the 2023 Peer Group, the compensation committee concluded that the previous peer group continued to include the most relevant companies for compensation comparison

purposes; however, Covanta Holding Corporation and Renewable Energy Group, Inc. were each removed from the peer group because they had been acquired and no longer remain independent publicly traded companies.

The compensation committee believes benchmarking may not always be the most appropriate tool for setting compensation due to aspects of our business, objectives, and the way we’ve structured executive roles that may be unique to us. The compensation committee considers internal equity, individual performance, tenure, recent pay levels, and input from our CEO and from our compensation consultant, among other factors, in determining final pay levels. The executive pay levels included in this proxy statement were determined based on all of the above factors, in conjunction with considering the peer group as stated above. As a result, the compensation committee retains discretion to vary executive compensation components and levels.
For compensation decisions in 2023, the compensation committee did not tie named executive officer compensation (either specific elements of compensation or total compensation levels) to any predetermined benchmark.
Review of Stockholder Say-on-Pay Votes
Consistent with the preference of our stockholders, which was most recently expressed at our annual meeting of stockholders held in May 2023, our stockholders can cast an advisory vote on executive compensation, or a “say-on-pay” vote, once every year. At the Company’s annual meeting of stockholders held in May 2023, our executive compensation received a favorable advisory vote from approximately 89.7% of the votes cast on the proposal at the meeting (which excludes abstentions and broker non-votes).
We believe the high degree of support on our 2023 say-on-pay proposal demonstrates that stockholders support our executive compensation program design.
We actively engage with our stockholders to discuss various compensation and governance matters and consider their feedback in determining named executive officer compensation. The compensation committee will also continue to consider the outcome of the Company’s say-on-pay votes, as well as this direct stockholder input, when making future compensation decisions for our named executive officers and in respect of our compensation program generally.
Components of Compensation
Our named executive officers’ compensation consists of the following components:

Base salary:

Performance-based annual cash incentives;

Equity incentives;

Change in control and post-termination severance compensation; and

Other benefits that are generally available to all of our salaried employees.
The compensation committee views the various components of compensation as distinct methods of achieving the various objectives of our compensation program and, as a result, it generally does not believe significant compensation derived from one component should negate or reduce compensation from other

38


components. The compensation committee does, however, review and evaluate each executive’s total compensation, and it may make decisions regarding levels of certain compensation components based on this evaluation of overall compensation, including, for instance, determinations regarding target levels under our performance-based cash incentive plan. The compensation committee also strives to provide an appropriate mix of long-term and short-term, cash and non-cash, and different forms of non-cash compensation; however, the compensation committee has not adopted formal plans or programs that allocate total compensation among these various characteristics.
Base Salary
We provide base salaries to recognize the experience, skills, knowledge, and responsibilities of our named executive officers; reward individual performance and contribution to our overall business goals; and retain our executives. The compensation committee reviews base salaries annually and relies on its judgment and discretion in determining the amount of each named executive officer’s base salary. Proposed base salaries are prepared by Mr. Littlefair and recommended to the compensation committee for its consideration and approval.
For 2021, the compensation committee determined to maintain Mr. Littlefair’s base salary at his 2020 level (it has been at the same level since 2015) and to increase the base salaries of Messrs. Vreeland, Pratt and Corbus by 13%, 8% and 8%, respectively. Messrs. Pratt’s and Corbus’ base salaries had not increased since 2014 and Mr. Vreeland’s base salary was increased to better align his compensation with his responsibilities and the base salaries of our other senior executives.
Base salaries for our named executive officers in 20202022 and 20212023 are as follows:

The base salary increase for Mr. Pratt includes an increase made in connection with his transition to the role of Chief Technology Development Officer in May 2023.
Cash Incentives
20212023 Performance-Based Cash Incentive Plan
Our compensation committee believes cash incentives are important to focus our management on, and reward our executives for, achieving Company financial and strategic objectives on an annual basis, as well as to deliver adequate retention value when combined with our other incentive programs, which may be denominated in equity and/or designed to incentivize performance over a longer term than annually. The compensation committee has the discretion to determine performance criteria, consider factors and developments it deems relevant and award overall cash incentives in the amounts it deems appropriate.

36


Each year our compensation committee approves a performance-based cash incentive plan and pays incentives after reviewing our performance with respect to the criteria set forth in the plan. Further, our compensation committee may, in its discretion, award additional special discretionary cash incentives for extraordinary efforts or performance by our named executive officers that the compensation committee believes are not otherwise covered by the performance criteria in our performance-based cash incentive plan. No discretionary cash incentive awards were made for 20212023 performance.
As further detailed in the table below, based on our performance for 2021,2023, the compensation committee awarded Mr. Littlefair ana cash incentive under our performance-based plan equal to approximately 108%62% of his target (or “middle”) incentive and awarded the other named executive officers ana cash incentive under our performance-based plan equal to approximately 106%60% of their target (or “middle”) incentives for 2021.2023, as indicated below.

Mr. Littlefair’s base salary used for purposes of cash performance bonus calculations was $778,680, which was his salary before taking a 10% voluntary pay reduction in 2015.
In February of 2021,April 2023, the compensation committee approved a 2023 performance-based cash incentive plan that included base, middle and maximum performance targets for each of the quantitative performance metrics described below. This was a returnbelow, noting that for 2023 the financial results for NG Advantage were evaluated separately and excluded from the 2023 performance-based cash incentive plan. The 2023 plan had the same design as our 2022 performance-based cash incentive plan, including the discretion afforded to our historic incentive plan design,compensation committee in determining performance criteria, performance targets, and unlike in 2020, we did not include any specific COVID-adjusted targets for 2021.actual payouts.
For 2021,2023, the total potential cash incentive award under our performance-based cash incentive plan for each of our named executive officers was based on the following, (theexclusive of the financial performance criteria are prepared by our Chief Financial Officer based on our annual budget, as amended, and the strategic initiatives are developed by our Chief Executive Officer):results for NG Advantage:


33%30% was based on our adjusted EBITDA, which is a non-GAAP financial measure described below;


25% was based on the volume of GGEs of RNG, CNG and LNG we delivered;

22%20% was based on the achievement (as determined in the compensation committee’s sole discretion) of certain specified strategic initiatives; and


20%15% was based on the volume of GGEs of natural gas fuel we delivered;

15% was based on the volume of RNG we delivered;

10% was based on our volume margin, as defined below;

5% was based on the volume-related, O&M services margin, as defined below; and

5% was based on the volume-related, O&M services margin percentage, as defined below.
We believe this combination of objective financial performance criteria that include both revenue and profitability measures, combined with tying a portion of the incentive to the achievement of strategic objectives, appropriately incentivized the named executive officers to achieve our business objectives for 2021.2023.
Performance Criteria.   For 2021, weCriteria for 2023:

Adjusted EBITDA:   We defined adjusted EBITDA as net income (loss) attributable to Clean Energy, plus (minus) income tax expense (benefit), plus interest expense (including any losses from the extinguishment of debt), minus interest income, plus depreciation and amortization expense, plus non-cash incentive contra-revenue charges (Amazon warrant charges), plus stock-based compensation expense, plus (minus) loss (income) from the SAFE&CEC S.r.l. equity method investments, and plus (minus) any loss (gain) from changes in the fair value of derivative instruments. Adjusted EBITDA is a non-GAAP financial measure. See “Calculation of 2023 Adjusted EBITDA” below in this Proxy Statement for the calculation of our 2023 adjusted EBITDA, as well as a reconciliation of adjusted EBITDA to net income (loss), which is the most comparable GAAP financial measure.

Strategic Initiatives:   Our strategic initiatives included winning a substantial portion of major fleet fueling business for natural gas vehicles, assisting and capitalizing on the introduction of the Cummins 15-liter engine, securing long-term RNG sources and driving RNG growth pipeline, lowering RNG project costs, working with state governments to maintain successful RNG policy, working to maximize RNG production tax credits, working with states to develop additional low carbon fuel standard (“LCFS”) programs, and solidifying our hydrogen strategy and position ourselves for opportunities.

Fuel Volume (in GGEs):   We defined the volume of GGEs of RNG, CNG and LNGnatural gas fuel we delivered as (1) the volume of GGEs we sell to our customers as fuel, plus (2) the volume of GGEs dispensed at

40


facilities we do not own but where we provide operation and maintenance services on a per-gallon or fixed fee basis, plus (3) our proportionate share of the GGEs sold as CNG by our joint venture, Mansfield Clean Energy Partners, LLC.
For 2021, we
RNG Volume (in GGEs):   We defined RNG volume as the amount of renewable natural gas fuel, in GGEs, delivered to our customers.

Fuel Volume Margin per GGE:   We defined fuel volume margin as gross profit margin from the volumes of natural gas and RNG CNG and LNGfuel we delivered, excluding gross profit margin from certain royalties and from our sales of credits we generate under federal and state programs by selling RNG and conventional RNG, CNG and LNG as a vehicle fuel, divided by the volumes of RNG, CNG and LNG we delivered (where “gross profit margin” is our fuel volume-related revenue, less our volume-related costexclusive of sales).
For 2021, we defined adjusted EBITDA as net income (loss) attributable to Clean Energy, plus (minus) income tax expense (benefit), plus interest expense, minus interest income, plus depreciation and amortization expense, plus stock-based compensation expense, plus (minus) loss (income) from equity method investments, and plus (minus) any loss (gain) fromnon-cash changes in the fair value of derivative instruments. See page 55fuel hedge derivatives and Amazon warrant charges, less our fuel volume-related cost of this proxy statement forsales, exclusive of depreciation).

Volume-related, O&M services Margin:   We defined volume-related, O&M services margin as gross profit margin from performing maintenance services on customer-owned fueling stations.

Volume-related, O&M services Margin %:   We define volume-related, O&M services margin percentage as gross volume-related O&M services revenue, less any costs to perform those services, divided by the calculation of our 2021 adjusted EBITDA, as well as a reconciliation of adjusted EBITDA to net income (loss), which is the most comparable GAAP financial measure.
gross volume-related O&M services revenue.

For 2021, our strategic initiatives included winning a substantial portion of Amazon’s business with respect to fueling its natural gas vehicles, securing at least 50 medium-duty truck orders, securing reauthorization of alternative fuel tax credit (“AFTC”) and working with the federal government to promote RNG initiatives, delivering 167.6 million GGEs of RNG, finalizing and beginning to implement joint ventures with BP and Total, and pursuing hydrogen projects and RNG initiatives.
The base, middle and maximum targets for the performance criteria under the incentive plan approved by our compensation committee for 2021,2023, as well as our actual performance for these criteria, are set forth in the following table. The middle target for each of our three financial performance criteria was set materially above our 2020 actual performance results, and required the executives to significantly improve on our 2020 actual performance results in order to earn a middle (target) bonus payment.

If each of the fourseven performance criteria are achieved at the base performance level, Mr. Littlefair would be entitled to an incentive payment equal to 70% of his target bonus (Mr. Littlefair’s base salary for purposes of bonus calculations was $778,680, which was his base salary before taking a 10% voluntary pay reduction in 2015), while the other named executive officers would be entitled to an incentive payment equal to 50% of their base salaries.

Equity Incentives
We believe long-term performance motivation is achieved through an ownership culture that encourages performance by our named executive officers through the use of stock-based awards. Our equity incentive plans have been established to provide certain of our employees, including our named executive officers, with incentives designed to align these employees’ interests with the interests of our stockholders. In general, the compensation committee develops its equity award determinations based on its judgments as to whether these equity awards are sufficient to further our ownership culture, appropriately align the interests of our named executive officers with those of our stockholders and retain, motivate, and adequately reward our executives on a long-term basis.
We have historically granted our named executive officers a combination of stock options and RSUs.RSUs, although in the past several years our named executive officers have received exclusively stock options. These awards are subject to both time-based and performance-based vesting requirements, and the compensation committee has exercised its judgment on the weighting of stock options relative to RSUs in any given year.
Time and Performance-Based Stock Options:


Afford the recipient the option to purchase shares of our common stock at a stated price per share.


All stock option awards granted under our equity incentive plans include an exercise price equal to the closing price of our common stock on the applicable grant date, and the grant date is always on or after the date of compensation committee approval.


Time-based stock option awards granted to our named executive officers typically vest at a rate of 34% on the one-year anniversary of the date of grant and 33% on each subsequent anniversary until fully vested, subject to the named executive officer’s continued service for our Company at each vesting date.


The vesting of performance-based options granted to our named executive officers generally requires the achievement of objective performance targets or the attainment of a premium price per common share that is set as a multiple of the closing price of a share of common stock on the grant date. In December of 2021, the compensation committee introduced two new types of performance-based stock option awards that are described in more detail below. The vesting of performance-based options is also subject to the named executive officer’s continued service for our Company at each vesting date.

Time and Performance-BasedPerformance- Based RSUs:


Full-value awards that represent the contingent right to receive shares of our common stock upon achievement of stated vesting criteria.


Time-based RSU awards granted to our named executive officers typically vest at a rate of 34% on the one-year anniversary of the date of grant and

33% on each subsequent anniversary until fully vested, subject to the named executive officer’s continued service for our Company at each vesting date.


The vesting of performance-based RSUs granted to our named executive officers generally requires the achievement of objective performance targets or the attainment of a premium price per common share that is set as a multiple of the closing price of a share of common stock on the grant date. The vesting of performance-based RSUs is also subject to the named executive officer’s continued service for our Company at each vesting date.
Equity Awards Granted in 20212023
In January 2021,February 2023, the compensation committee awarded time-based RSUs and stock options to our named executive officers in the amounts set forth in the table below. The compensation committee granted stock option and RSU awards with time-based vesting in orderofficers. In 2023, our equity grants to provide greater certainty of vesting and value while still incentivizing long-term performance over time, after taking into account the status of our named executive officers’ then-outstanding equity awards, volatility in our stock price due to general market and industry conditions, the greater valueofficers consisted entirely of RSUs to executives due to their full-value nature, and the need for stock price appreciation to provide any value with stock option awards. For the January grants, the mix of RSUs and stock options was determined based onthat vest over 3 years and expire at the factors described above, with a target proportionend of 40% of the total shares subject to each executive’s equity awards being in the form of RSUs and 60% of the total shares subject to each executive’s equity awards being in the form of stock options.

These RSUs are subject to the terms and conditions of the 2016 Plan and a Notice of Grant of Restricted Stock Unit and Restricted Stock Unit Agreement, and vest according to the typical three-year vesting schedule described above.

In addition to his stock option award, Mr. Pratt was also granted an equity award in the Company’s subsidiary, CLNE PlasmaFlow Holdings, LLC. In connection with Mr. Pratt’s transition from Chief Operating Officer to Chief Technology Development Officer in May 2023, he is expected to devote a portion of his time to growing the CLNE PlasmaFlow business, and this separate equity award was intended as an incentive to motivate Mr. Pratt to drive value creation in this portion of the Company’s business. Mr. Pratt’s CLNE PlasmaFlow equity award is structured as a “profits interest” and vested immediately upon grant.
Current Performance of 2021 Performance Stock Options
In December of 2021, the compensation committee met and it determinedawarded two performance-based stock options as additional long-term incentives to our named executive officers. At that time, the Company was at a critical juncture, and the compensation committee determined that it was of primary importance to incentivize the named executive officers to (1) create long-term stockholder value by increasing the Company’s price per share and (2) strategically execute on expanding the Company’s RNG business over the long-term.long term and to create long term stockholder value by increasing the Company’s price per share. These awards have the following performance characteristics:
1) RNG Performance Options — The compensation committee decided to introduce two new types of performance-based stock option awards into our executive compensation program, and made grants of these performance-based stock option awards along with additional time-based stock options to each of the named executive officers in December. The December grants represent the largest component of each named executive officer’s 2021 compensation andRNG performance Options are intended to provide a meaningful performance-based equity incentive over a number of years going forward to incentivize the executives to execute our transformative strategy. Although the size of the December grants was larger than our historical grants, over 50% of the grant date value of each executive’s grant (and approximately 66% of the grant date value of Mr. Littlefair’s grant) will only vest and have any value to the executives if we are able to increase the closing price of our common stock by a greater than 100% premium above the closing price on the grant date.
The first new performance-based option is structured to incentivize long-term RNG growth and the vesting of 100% of each grant is subject to the Company’s attainment of four separate RNG supply through investment milestones. In 2021, RNG sales represented 78% of our total vehicle fuel sales. In order to achieve our five-year strategic plan and achieve our projected five-year RNG volume, revenue and income goals, we

40


believe we will need to make significant capital investments in order to increase our RNG supply through investment. The performance-based options are structured so that there are four separate vesting tranches, with each tranche requiring us to secure 15 million GGEs of RNG supply via investment in order to vest (i.e., the first tranche will vest if we secure 15 million GGEs of RNG supply via investment, the second tranche will vest if we secure an additional 15 million GGEs of RNG supply via investment for a total of 30 million GGEs, the third tranche will vest if we secure an

43


additional 15 million GGEs of RNG supply via investment for a total of 45 million GGEs and the final tranche will vest if we secure an additional 15 million GGEs of RNG supply via investment for a total of 60 million GGEs). We believe these represent challenging multi-year goals that if the named executive officers are able to achieve, will help drive our transformative strategic plan and the achievement of our future RNG volume, revenue and income goals. Each named executive officer must also remain in continued service for our Company at each vesting date in order to vest. As of the record date of the Annual Meeting, one tranche of these options have vested — however, because the strike price on the date of grant — $6.77 — is greater than our trending share price, these options are currently underwater. We believe these options still hold motivational and retentive value to our executives given our belief in the long-term growth potential of the business.
2) Premium Share Price Performance Options — The second new performance-based option was the largest component of each executive’s December grant and is structuredPremium Share Price Performance options are intended to incentivize long-termthe appreciation in the value of our shares. The vesting of 100% of each grant is subject to our attainment of a stock price representing a greater than 100% premium above the closing price of a share of common stock on the grant date. In order for these performance-based options to vest, we must achieve an average closing price equal to or above $14.00 per share over a twenty consecutive trading day period. Each named executive officer must also remain in continued service for our Company on the vesting date in order to vest.
Each named executive officer was also awarded an additional grant As of time-based options that vest according to the typical three-year vesting schedule described above.
AllRecord Date, this price threshold has not been achieved and accordingly, none of these December stock options are subject to the terms and conditions of the 2016 Plan and a Notice of Grant of Stock Option and Stock Option Agreement, and have an exercise price of $6.77 per share.

As discussed above, the compensation committee spent significant time in the third and fourth quarters of 2021 evaluating the structure of our long-term equity incentive awards and designing our two new types of performance-based options. Once the design of our performance-based options was approved, the compensation committee determined to grant the named executive officers their long-term incentive awards in December of 2021 and in light of these awards has also determined to make no further long-term incentive awards in 2022. This shift in grant timing had the effect of increasing Messrs. Littlefair’s, Vreeland’s, Pratt’s and Corbus’ 2021 compensation by $6,537,500, $2,826,750, $2,826,750 and $2,941,250, respectively. Because of the December grants, the compensation committee determined it will not grant any additional equity awards to named executive officers in calendar 2022.vested.
Change in Control and Post-Termination Severance Compensation
Our employment agreements with our named executive officers, described under “Employment Agreements” below, provide them certain benefits if their employment is terminated, including a termination following a change in control but excluding a termination by the Company for cause or a voluntary termination by the named executive officer without good reason. The compensation committee believes these benefits are important tools for retaining the services of our named executive officers and helping to align the interests of our named executive officers with those of our stockholders. The details and amounts of these benefits are described below under “Executive Compensation — Potential Payments Upon Termination or Change in Control.”

41


All equity awards granted to our named executive officers after November 2014 including the RSUs and stock options awarded to our named executive officers in 2021, are subject to double-trigger vesting upon a change in control. The compensation committee previously determined to modify the standard vesting provisions of our named executive officers’ equity awards from “single-trigger” to “double-trigger” vesting in connection with a change in control because it believes double-trigger vesting more accurately reflects current market practices but still provides appropriate benefits to executives in the event of a termination in connection with a change in control, and is thus in the best interests of our Company and our stockholders. Further, we do not provide any excise tax “gross-up” payments to our executives in connection with a change in control.
Other Benefits
We appreciate the tremendous value and contributions of our employees, and we believe providing a competitive employee benefits program is one of our most important investments. As a result, we offer an employee benefits program with a wide range of plans designed to promote the health and personal welfare of all employees, including our named executive officers. Participation in these plans is generally available to all of our employees on the same basis. The Company provides minimal perquisites to executives which are noted in the description of “All Other Compensation” disclosed in the Summary Compensation Table on page 45.of this Proxy Statement.
Employment Agreements
We entered into employment agreements with each of our named executive officers on December 31, 2015.2015 (and entered into an amended employment agreement with Mr. Pratt in May 2023 in connection with his transition to a non-executive officer position). These employment agreements have the following key terms:


Each employment agreement, other than Mr. Pratt’s, is passed its initial three-year term and now automatically renews on December 31 for additional one-year periods (unless either party provides

44


notice of non-renewal). The initial term of Mr. Pratt’s employment agreement runs through May 17, 2025 and automatically renews thereafter for additional one-year periods (unless either party provides notice of non-renewal).


Each named executive officer is entitled to receive an annual base salary of no less than his base salary in 2015.2015, other than Mr. Pratt, who is entitled to receive an annual base salary of no less than his base salary under the new employment agreement, $550,000.


Each named executive officer is eligible to receive an annual cash incentive of up to a specified percentage of his then-current annual base salary under the terms of our performance-based cash incentive plan in effect for the applicable year. Mr. Littlefair is eligible to receive 70%, 100% or 150% of $778,680 for our achievement of the base, middle and maximum performance targets, respectively, and we consider achievement of the middle performance targets to be Mr. Littlefair’s target incentive amount; each of Messrs. Vreeland, Pratt, and Corbus is eligible to receive 50%, 70% or 100% of his respective base salary for our achievement of the base, middle and maximum performance targets, respectively, and we consider achievement of the middle performance targets to be Messrs. Vreeland’s Pratt’s, and Corbus’ target incentive amount.


Each named executive officer would be entitled to receive certain severance compensation and benefits under certain circumstances upon a termination of the named executive officer’s employment with us. The details of this severance are described below under “Executive Compensation —  Potential Payments Upon Termination or Change in Control.” The employment agreements condition severance payments on a so-called “double-trigger” upon a change in control. The employment agreements also do not include any “gross-up” provision for any excise taxes that may be triggered in connection with a change in control under Sections 280G and 4999 of the Code, and instead include a “best-net” cutback provision under which benefits are reduced to avoid triggering any such excise taxes unless the after-tax benefit is greater to the named executive officer without the cutback. The compensation committee determined that these terms are appropriate because they better align our severance and change of control payment practices with current market expectations and the interests of our named executive officers with those of our stockholders, while still providing a level of benefits the compensation committee believes is fair and reasonable and maintaining the retention value of these benefits.
Other Compensation Policies
Executive Stock Ownership Guidelines
We believe it is important to encourage our named executive officers to hold a material amount of our common stock, which links their long-term economic interest directly to that of our stockholders. To achieve

42


this goal, we have established stock ownership guidelines applicable to our named executive officers. The compensation committee recently examined our current stock ownership guideline levels relative to market practice and made adjustments to further align executive interests with our stockholders. These updated guidelines provide that our Chief Executive Officer is required to own shares of our common stock valued at threefive times his annual base salary (vs. three, previously) or more, and each of our Chief Financial Officer, Chief Operating Officer, Chief Marketing Officer, Senior Vice President, Strategic Development, and Senior Vice President, Sales, in each case if any person is appointed in such position,other named executive officers is required to own shares of our common stock valued at one and one half times his annual base salary (vs. one, previously) or more. Such level of ownership must be attained by the later of December 14, 2019 andwithin five years after the date of an executive officer’s initial appointment as such. Stock options are not counted toward satisfaction of these stock ownership requirements. Executives who attain the applicable stock ownership level by the stated deadline will continue to satisfy the stock ownership requirements if the value of their stock holdings declines after such deadline solely due to a decrease in the trading price of our common stock. Each of our named executive officers had satisfied these stock ownership guidelines as of the record date forRecord Date.
We have also adopted an equity award grant policy that we believe aligns with best corporate governance practices. Our general policy is to grant equity awards no less than 1 business day after the filing of our Annual Meeting.Report filed on Form 10-K, although we do have the discretion to grant equity awards at other times if determined to be appropriate by the compensation committee.

Our policies do not permit any of our executive officers or directors to “hedge” ownership of our securities by engaging in short sales or trading in put options, call options or other derivatives involving our securities. This means that our employees and directors may not purchase financial instruments or otherwise engage in transactions that hedge or offset, or are designed to hedge or offset, any decrease in the market value of our equity securities. Further, our policies do not permit an executive officer or director to hold our securities in a margin account or pledge our securities as collateral for a loan unless the executive officer or director demonstrates to our satisfaction financial capacity to substitute other assets for Company securities in the event of a failure to meet a margin call or a default on the loan.
As of the date of this Proxy Statement, none of our directors or executive officers has pledged any of the shares of our common stock he or she owns.
Clawback Policy
The compensation committee has adopted a formal clawback policy regarding recoupment, or a “clawback,” of cash compensation in certain circumstances. Our clawback policy was amended in 2023 to comply with the latest SEC and NASDAQ clawback policy requirements. The purpose of this clawback policy is to help ensure that executives act in the best interests of the Company and our stockholders. The clawback policy requires certain of our officers, including our named executive officers, to repay or return any cash incentive or other incentive cash compensation awarded to or received by such officer(s) in the event we issue a restatement of our financial statements due to material noncompliance with any financial reporting requirements and the restatement was caused by such officer’s fraud, intentional misconduct or gross negligence. In each case, the officer(s) would be required to repay or return the incentive cash compensation awarded to or received by the officer during the 12-month period following the filing of the erroneous financial statement at issue. Pursuant to the clawback policy, in the event of any restatement of our financial statements, the compensation committee would consider a number of factors and exercise its business judgment in determining appropriate amounts, if any, to recoup. Further, the compensation committee retains the discretion to adjust or recover awards or payments if the relevant performance measures on which they are based are restated or are otherwise adjusted in a manner that would reduce the size of the award or payment. The clawback policy applies to cash compensation awarded to our officers from and after the date of its adoption.
Tax and Accounting Effects
In designing our compensation programs, the compensation committee considers the financial impact and tax and accounting effects that each element of compensation will or may have on the Company and our executives. One such area the compensation committee considers is the tax deductibility of each component of executive compensation. Prior to December 22, 2017, when the Tax Cuts and Jobs Act of 2017 (“TCJA”) was signed into law, Section 162(m) generally prohibited us from taking a tax deduction in any tax year for compensation paid to certain executive officers that exceeded $1,000,000, unless the compensation was payable only upon the achievement of pre-established, objective performance goals under a plan approved by our stockholders. As a result, we believe certain stock option and RSU awards we granted to our named executive officers before the impact of the TCJA have qualified as performance-basedperformance- based compensation under Section 162(m), although there is no guarantee that such equity awards, or any

43


other performance-based compensation paid to our named executive officers, qualify as such. Under the TCJA, the exception for performance-based compensation under Section 162(m) has been repealed, so that the $1,000,000 limit on tax deductions in a tax year generally applies to anyone serving as our chief executive officer or our chief financial officer at any time during a taxable year as well as our top three other highest-compensated executive officers serving at fiscal year-end. These changes generally do not apply to compensation provided pursuant to a binding written contract in effect on November 2, 2017 that is not modified in any material respect after that date. The compensation committee reserves the discretion to make any executive compensation decisions that it considers to be in the best interests of our Company and our stockholders, including to award compensation that may not be deductible or to amend existing compensation arrangements in a manner that could limit their deductibility.

Includes an award of 833,334 profit interest units to Mr. Pratt under the CLNE PlasmaFlow Holdings, LLC 2023 Equity Incentive Plan, in connection with his transition to Chief Technology Development Officer.
Employment Agreements
On December 31, 2015, we entered into an employment agreement with each of our named executive officers. See the description under “Compensation Discussion and Analysis — Employment Agreements” and below under “Potential Payments Upon Termination or Change in Control” for more information. In connection with Mr. Pratt’s transition from Chief Operating Officer to Chief Technology Development Officer, we entered into an amended employment agreement with Mr. Pratt on May 17, 2023. Mr. Pratt’s amended employment agreement has a two-year term that automatically renews for successive one-year periods unless earlier terminated in accordance with the provisions therein, provides Mr. Pratt with a $550,000 annual base salary, and is otherwise consistent in all material respects with Mr. Pratt’s previous employment agreement.
Pension Benefits, Non-Qualified Defined Contribution and Other Deferred Compensation Plans
We do not have any defined-benefit plans that provide for payments or other benefits to our named executive officers at, following or in connection with their retirement. We also do not have any non-qualified defined contribution plans or other deferred compensation plans that provide for the deferral of compensation on a basis that is not tax-qualified.
Potential Payments Upon Termination or Change in Control
The narrative and tables below describe the amount of compensation to be paid to our named executive officers in the event of a termination of employment or a change in control. The amount of compensation payable to each of our named executive officers upon a voluntary termination, voluntary termination for good reason, involuntary without cause termination, failure by us to renew the named executive officer’s employment agreement upon its expiration, for-cause termination, change in control of our Company, termination in connection with a change in control and termination due to disability or death is shown in tabular format. Except as otherwise noted, the amounts shown in these tables assume that each such termination or change in control was effective as of December 31, 2021,2023, and thus are estimates of the amounts that would be paid to our named executive officers upon an actual termination or change in control because such amounts could only be determined at the time of such an actual termination or change in control. The amounts shown in these tables are based on the terms of each named executive officer’s employment agreement with us and the terms of agreements relating to each named executive officer’s outstanding equity awards.

52


Severance Compensation under Employment Agreements
Pursuant to the terms of the employment agreement for each named executive officer:


If we terminate a named executive officer without “cause” ​(as such term is defined in the employment agreement), if a named executive officer resigns for “good reason” ​(as such term is defined in the employment agreement) or if we do not renew the employment agreement before expiration of the term or any renewal term, then the named executive officer would be entitled to (1) a lump-sum payment of an amount equal to the sum of (A) his annual base salary earned through the date of termination and any annual cash incentive earned for the prior year to the extent not previously paid, (B) any compensation previously deferred by the named executive officer (together with any accrued interest or earnings thereon), (C) 150% of one year’s then-current annual base salary, (D) 150% of his previous year’s annual cash incentive actually earned under our performance-based cash

49


incentive plan, and (E) any vacation pay accrued and not paid as of the date of termination; (2) after the end of the calendar year in which the termination occurs, a lump-sum payment of an amount equal to the annual cash incentive that would be payable to the named executive officer under our performance-based cash incentive plan in respect of such year (based on the criteria applicable for that year) without any pro-rating; and (3) continuing participation, at our expense, for a period of one year from the date of termination in the benefit programs in which the named executive officer was enrolled at the time of termination.


If we terminate any named executive officer’s employment without cause or do not renew his employment agreement within six months before or one year after the date of a “change in control” (as such term is defined in the employment agreement), or if a named executive officer resigns for good reason within six months before or one year after the date of the change in control, then the named executive officer would be entitled to the severance compensation described above, except that the lump-sum payment described in (1) above for all named executive officers except Mr. Littlefair would consist of 225% of his then-current annual base salary, 225% of his previous year’s annual cash incentive actually earned under our performance-based cash incentive plan, and the amounts described in (A), (B) and (E); and the lump-sum payment described in (1) above for Mr. Littlefair would consist of 300% of his then-current annual base salary, 300% of his previous year’s annual cash incentive actually earned under our performance-based cash incentive plan, and the amounts described in (A), (B) and (E).


If any named executive officer ceases to be an employee due to death or disability, then the named executive officer would be entitled to the amounts described in (1)(A),(B) and (E) and (2) above, except that the amount described in (2) above would be pro-rated based on the number of weeks during the last fiscal year during which the named executive officer was an employee.


If, at any time that our common stock is not listed or quoted on a national securities exchange or an over-the-counter quotation system, (i) the employment of either of Messrs. Littlefair or Pratt is terminated for cause, we would be entitled, at our option, to repurchase all or a portion of our stock owned by him, or (ii) the employment of either of these named executive officers is terminated due to death or disability, we would be required to repurchase all of our stock owned by him.
In consideration of the receipt of any of the severance compensation described above and as a precondition to their receipt, each named executive officer would be required to execute and deliver, and not revoke, a release in favor of us in the form attached to his employment agreement. For purposes of the tables below, we have assumed that the amounts described in (1)(A) and (B) above have already been paid to the applicable named executive officer or are $0.
For purposes of each such named executive officer’s employment agreement:


“Cause” means (1) the named executive officer committing a material act of dishonesty against us, (2) the named executive officer being convicted of a felony involving moral turpitude or (3) the named executive officer committing a material breach of his confidentiality, trade secret, non-solicitation or invention assignment obligations under his employment agreement.


“Good reason” means the named executive officer resigns from his employment after we (1) have materially diminished the named executive officer’s duties, authority, responsibility, annual base salary

53


or annual incentive compensation opportunity, (2) materially breach the employment agreement; (3) change the person to whom the named executive officer reports, or (4) change the location of the named executive officer’s principal place of employmentemployment.


“Change in control” means (1) any “person” ​(as defined or referred to in Section 3(a)(9) and/or 13(d)(1), et seq. of the Exchange Act and the associated rules of the SEC promulgated thereunder), other than an existing stockholder of the Company as of January 1, 2006, is or becomes the “beneficial owner” ​(as defined in Rule 13d-3 under the Exchange Act), directly or indirectly, of securities of the Company representing 40% or more of the combined voting power of our then-outstanding securities, or (2) a merger or consolidation of the Company in which its voting securities immediately before the merger or consolidation do not represent, or are not converted into securities that represent, a majority of the combined voting power of all voting securities of the surviving entity immediately after the merger or consolidation, or (3) a sale, lease, exchange or other transfer (in one transaction or a

50


series of related transactions) of all or substantially all of the assets of the Company or a liquidation or dissolution of the Company, or (4) individuals who, as of the date of the employment agreement, constitute the Company’s board of directors (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Company’s board of directors; provided that, other than in connection with an actual or threatened proxy contest, any individual who becomes a director subsequent to the date of the employment agreement whose election, or nomination for election by the stockholders of the Company, was approved by the vote of at least a majority of the directors then in office shall be deemed a member of the Incumbent Board.
Vesting of Options and RSUs
The terms of the option awards granted to our named executive officers provide that all unvested options will be forfeited if the named executive officer’s employment with the Company is terminated for cause (as defined in his employment agreement) or voluntarily by the named executive officer before their applicable vesting date, that all unvested options will vest in full if the named executive officer’s employment is terminated by the Company without cause (as defined in his employment agreement), and that all vested options will generally continue to be exercisable for three months after the date of any such termination. The terms of the RSU awards granted to our named executive officers provide that all unvested RSUs will be forfeited if the named executive officer’s employment with the Company is terminated by the Company for cause or voluntarily by the named executive officer before their applicable vesting date, and that all unvested RSUs will vest in full if the named executive officer’s employment is terminated by the Company without cause or if the named executive officer ceases to be an employee due to death or disability before their applicable vesting date.
If the Company experiences a “change in control,” as defined in the 2016 Plan, then each such named executive officer’s option and RSU awards that are outstanding on the date that immediately precedes the change in control will (A) if such awards are not assumed or replaced by the successor company in the change in control, immediately vest in full and, if applicable, become fully exercisable on the date of the change in control, or (B) if such awards are assumed or replaced by the successor company in the change in control but the named executive officer’s employment is terminated by the successor company without cause or by the named executive officer for good reason within 12 months following the change in control (based on the definitions of “cause” and “good reason” in his employment agreement with us), immediately vest in full and, if applicable, become fully exercisable on the date of such termination.
For purposes of the tables below, the “spread” value (i.e., the excess of $6.13$3.83 per share, which was the closing price of our common stock on December 31, 2021,29, 2023, over the applicable option exercise price) of unvested option awards that were “in the money” on December 31, 202129, 2023 is presented.

Pay Ratio
We are required by applicable SEC rules to disclose the annual total compensation of our Chief Executive Officer, the median annual total compensation of all of our other employees, and the ratio of these two amounts.

TABLE OF CONTENTS

In determining the median annual total compensation of our employees other than our Chief Executive Officer, we started by preparing a list of all such employees as of December 31, 20212023 and each such employee’s taxable earnings for 20212023 as reflected in our payroll records, which generally consists of salary; regular, hourly, and overtime wages; commissions; incentives and other miscellaneous earnings. This list includes all our employees on such date (except solely for our Chief Executive Officer), whether employed on a full-time, part-time, seasonal or temporary basis and wherever located, resulting in 443559 employees who are all located in the United States.States and Canada. For any such employees who are permanently employed (in other words, who are not employed on a seasonal or temporary basis) and who joined the Company after January 1, 2021,2023, this list reflects 20212023 taxable earnings on an annualized basis. We then ordered the employees in this list based on the amounts of their 20212023 taxable earnings, selected the single employee at the midpoint of the re-ordered list, and calculated the amount of this single midpoint employee’s annual total compensation using the methodology required by SEC rules for calculating the total compensation of our named executive officers as reported in the Summary Compensation Table above. The annual total compensation for our median employee was $130,294,$105,469, and the annual total compensation for our Chief Executive Officer was $10,811,193.$1,977,858. We estimate the ratio of the annual total compensation of our Chief Executive Officer to the median annual total compensation of all our other employees is 8319 to 1.
We believe this pay ratio is a reasonable estimate calculated in a manner consistent with applicable SEC rules. In light of the many different methodologies, exclusions, estimates and assumptions companies are permitted to use in determining an estimate of their respective pay ratios, as well as the differing employment and compensation practices and industry standards that impact these ratios, our estimated pay ratio information may not be comparable to the pay ratio information reported by other companies, and we discourage the use of this information as a basis for comparison between companies. Neither our compensation committee nor our management used our pay ratio information in making compensation decisions for 2023 or 2024.
Pay Versus Performance
Under rules adopted pursuant to the Dodd-Frank Act, we are required to disclose certain information about the relationship between the compensation actually paid to our named executive officers and certain measures of company performance. The material that follows is provided in compliance with these rules; however, additional information regarding our compensation philosophy, the structure of our performance-based compensation programs, and compensation decisions made this year is described above in our “Compensation Discussion and Analysis.”
The following table provides information regarding compensation actually paid to our principal executive officer, or PEO, and other NEOs for each year from 2020 to 2023, compared to our total stockholder return (“TSR”) from December 31, 2019 through the end of each such year, and our Net Income, and Adjusted EBITDA for each such year.

SEC rules require certain adjustments be made to the Summary Compensation Table totals to determine “compensation actually paid” as reported in the Pay versus Performance Table. “Compensation actually paid” does not necessarily represent cash and/or 2022.equity value transferred to the applicable NEO without restriction, but rather is a value calculated under applicable SEC rules. In general, “compensation actually paid” is calculated as Summary Compensation Table total compensation adjusted to include the fair market value of equity awards as of December 31 of the applicable year or, if earlier, the vesting date (rather than the grant date). NEOs do not participate in a defined benefit plan so no adjustment for pension benefits is included in the table below. Similarly, no adjustment is made for dividends as dividends are factored into the fair value of the award. Finally, there were no equity awards which were granted and vested in the same year, other than the award of profits interest granted to Mr. Pratt in 2023 under the CLNE PlasmaFlow Holdings, LLC 2023 Equity Incentive Plan.

Risks Related to Compensation Policies and Practices
The compensation committee regularly monitors and considers whether our overall compensation programs, including our executive compensation program, create incentives for employees to take excessive or unreasonable risks that could materially harm our Company. Although risk-taking is a necessary part of any business, the compensation committee focuses on aligning the Company’s compensation policies with the long-term interests of the Company and its stockholders and avoiding short-term rewards for management decisions that could pose long-term risks to the Company. Although a portion of our executive compensation plan is performance-based, which could motivate risk-taking, we do not believe our overall compensation structure encourages excessive or unnecessary risk-taking. We believe our approach to goal-setting, the mix of different types of compensation, payouts at multiple levels of performance, evaluation of performance results, and allowance for compensation committee discretion in determining award types, levels and payouts assist in mitigating these risks, as follows:


Our compensation structure includes a combination of compensation vehicles, including a competitive base salary and benefits generally available to all of our employees, equity awards to incentivize long-term performance and align the interests of our employees with those of our stockholders, annual

cash incentives to reward executives for achieving Company objectives, and change in control and post-termination severance compensation to encourage retention of our key executives.


To discourage excessive or unnecessary risk-taking, for 2021,2023, payouts to each named executive officer under our performance-based cash incentive plan were based on fourseven distinct performance metrics, each with material weighting. Additionally, the compensation committee retains the discretion to increase or decrease payouts under this incentive plan as it deems appropriate.


To help mitigate risks of overpayment, due to fraudulent, intentional or grossly negligent errors, ourwe maintain a clawback policy permits us, under certain circumstances,that complies with recently adopted SEC and Nasdaq requirements. We also have adopted stock ownership guidelines applicable to recover certain cash compensationall of our named executive officers to ensure they have a meaningful equity stake in the event of a restatement of our financial statements or excess payments of performance-based compensation in the event of a restatement or other adjustment of the performance measures on which the payments are based.Company.
We further believe that our internal legal and financial controls appropriately mitigate the probability and potential impact of an individual employee committing our Company to a harmful long-term business transaction in exchange for a short-term compensation benefit.

Based on the factors described above, we believe our 20212023 compensation programs do not create risks that are reasonably likely to have a material adverse effect on our Company.

DIRECTOR COMPENSATION
Overview
We use cash and equity compensation to attract and retain qualified candidates to serve on our Board. The amount and type of cash and equity compensation awarded to non-employee directors isin 2023 was determined by the compensation committee each year in its sole discretion. In setting non-employee director compensation for 2023, the compensation committee considersconsidered a variety of factors, including the significant amount of time that our directors spend in fulfilling their duties to our Company, as well as the level of experience and skill required of the members of the Board. We have also awarded compensation to individual non-employee directors or directors serving in certain positions on our Board or its committees in recognition of outstanding service or efforts on the Company’s behalf. Further, in setting director compensation, our compensation committee considersconsidered that a director’s independence may be jeopardized if director compensation and perquisites exceed customary levels, if the Company makes charitable or political contributions to organizations with which a director is affiliated or if the Company enters into consulting contracts with (or provides other indirect forms of compensation to) a director or an organization with which a director is affiliated. Directors who are our employees receive no additional compensation for their services as directors. In addition, for 20212023 and 20222024 each of Messrs. Charleux, Maurisse, andMr. Soulas, Mr. Wolffsheim and Ms. Boissy-Rousseau voluntarily waived their right to receive compensation for their services as a director of our Company.
In November 2022, following consultation with the compensation committee’s independent compensation consultant, Semler Brossy, we adopted our new Directors’ Compensation Policy, effective January 1, 2023. We adopted our new Directors’ Compensation Policy to formalize our director compensation arrangements and director equity award grant practices, and we believe our new policy will facilitate our Board’s mission of attracting and retaining highly skilled directors.
After reviewing the factors described above and others that it considered relevant, the compensation committee approved the non-employee director compensation program described below for 2021 and 2022 compensation.below. The compensation paid pursuant to the non-employee director compensation program is described below.
Cash
For 20212023 and 2022,2024, our non-employee directors (other than Messrs. Charleux, Maurisse andMr. Soulas, Mr. Wolffsheim and Ms. Boissy-Rousseau) received (or will receive) the following cash compensation:
Type of Retainer or Fee2023 Amounts2024 Amounts
Annual Cash Retainer$70,000$70,000
Annual Chairperson Retainer$60,000$60,000
Annual Audit Committee Chairperson Retainer$15,000$15,000
Annual Compensation Committee Chairperson Retainer$10,000$10,000
Annual Nominating and Corporate Governance Committee Chairperson Retainer$5,000$5,000
Annual Audit Committee Member Retainer$5,000$5,000
Annual Compensation Committee Member Retainer$4,000$4,000
Annual Nominating and Corporate Governance Committee Member Retainer$3,000$3,000

These cash retainers will be paid on a quarterly basis, following the end of each quarter in arrears, and will be pro-rated if a non-employee director serves (or serves in the corresponding position, as the case may be) for only a portion of the quarter.
All of ourEquity
Pursuant to the Directors’ Compensation Policy, effective January 1, 2023, the non-employee directors receive base cash compensationan annual equity award with a value of $60,000 per year;

Audit committee members (other than the Chairman) receive an additional $2,500$120,000, which award shall be fifty percent (50%) in cash compensation per yearnon-statutory stock options (the “Annual Stock Option Award”) and fifty percent (50%) in recognition of their additional responsibilities;

The Chairmanrestricted stock units of the audit committee receives an additional $10,000 per year in recognitionCompany (collectively with the Annual Stock Option Award, the “Equity Awards”). Equity awards are generally granted to Directors on the date of his additional responsibilities; and

The Chairman of the Board receives an additional $60,000 per year in recognition of his additional responsibilities.
Equity
Each non-employee director (other than Messrs. Charleux, Maurisse and Wolffsheim and Ms. Boissy-Rousseau) received an option award on January 21, 2021 for a number of shares equal to a grant date fair value of approximately $579,000 and an option award on December 7, 2021 for a number of shares equal to a grant date fair value of approximately $438,000, except for Ms. Paskett who received only an option award on December 21, 2021 for a number of shares equal to a grant date fair value of approximately $420,000, all of which will be vested in one year from each option award date. The compensation committee chose to award options (rather than RSUs or a combination of RSUs and options) in 2021 based on, among other things, its determination that our non-employee directors preferred option awards and the compensation committee’s desire to limit depletion of the 2016 Plan’s share limit (each share of common stock issued in respect of RSUs awarded under the 2016 Plan is counted against the share limit as 1.5 shares, whereas each share of common stock issued in respect of options awarded under the 2016 Plan is counted against the share limit as 1.0 share).
The December option awards were grantedAnnual Meeting. Subject to the non-employee directorsdirector’s continued service with the Company, each Equity Award will vest in lieu of making any annual long-term equity awards toone installment on the directors in 2022.

Director Stock Ownership Guidelines
We believe it is important to encourage our directors to hold a material amount of our common stock, which links their long-term economic interest directly to that of our stockholders. To achieve this goal, we have established stock ownership guidelines applicable to our independent directors. These guidelines provide that each independent director is required to own shares of our common stock valued at $180,000 or more by five years after the date of a director’s initial election to the Board. Stock options are not counted toward satisfaction of these stock ownership requirements. Directors who attain this stock ownership level by the stated deadline will continue to satisfy the stock ownership requirements if the value of their stock holdings declines after such deadline solely due to a decrease in the two equity awards granted to the non-employeetrading price of our common stock.

This does not include employment compensation or compensation for Board service, which are described elsewhere in this Proxy Statement.
Relationships with TotalEnergies and its Affiliates
During 2021,2023, the Company recognized revenue of $3.3$1.4 million and $0.4 million, respectively, related to RINs and LNG sold to TotalEnergies and its affiliates in the ordinary course of business and AFTC creditsAFTCs associated therewith.
TheDuring 2023, the Company purchased $0.6paid TotalEnergies $6.9 million in parts and materials from TotalEnergiesfor expenses incurred in the ordinary course of business during 2021.and settlements on commodity swap contracts.
TotalEnergies Agreements
On May 9, 2018, we entered into a stock purchase agreement (the “Purchase Agreement”) with TMSTotalEnergies Marketing Services, SAS (“TMS”) for the sale and issuance to TMS of up to 50,856,296 shares of our common stock, representing approximately 25% of the outstanding shares of our common stock and the largest ownership position of our Company, for a per share purchase price of $1.64 and an aggregate cash purchase price of $83.4 million. The TotalEnergies private placement closed on June 13, 2018.
Pursuant to the Purchase Agreement, TMS has the right to designate up to two individuals to serve as directors on our Board. Subject to certain limited conditions as described in the Purchase Agreement, including compliance with our governing documents and all applicable laws, rules and regulations, we will be obligated to appoint or nominate for election as directors of our Company the individuals so designated by TMS and, from and after such appointment or election, either (1) appoint one of these individuals to serve on the audit committee of the Board and any other Board committees that may be formed from time to time for the purpose of making decisions that are strategically significant to our Company, or (2) nominate another individual as an observer of such Board committees, who is to be invited to attend all meetings of such committees in a non-voting observer capacity. TMS’ rights and our obligations relating to these designees and observers continue until (and if) (a) with respect to TMS’ right to designate two individuals to serve as directors on our Board and an optional observer to serve on certain Board committees, TMS’ voting power is less than 16.7% but more than 10.0%, and (b) with respect to TMS’ right to designate one individual to serve as a director on our Board and an optional observer to serve on certain Board committees, TMS’ voting power is less than 10.0%, in each case measured in relation to the votes then entitled to be cast in an election of directors by our stockholders.
The Purchase Agreement also provides that, until the later of May 9, 2020 or such date when TMS ceases to hold more than 5% of our common stock then outstanding, among other similar undertakings and subject to customary conditions and exceptions, TMS and its affiliates are prohibited from purchasing shares of our common stock or otherwise pursuing transactions that would result in TMS owning more than 30% of our equity securities without the approval of our Board.
In connection with the Purchase Agreement on May 9, 2018, we and all of our then-directors and officers entered into a voting agreement with TMS. Pursuant to the voting agreement, each of our directors and officers agreed to vote all shares of our common stock presently or hereafter owned or controlled by such director or officer, in any vote of our stockholders that may be held from time to time, in favor of the election of the individuals designated by TMS to serve as directors on our Board. Each of our directors and officers has also granted to TMS a proxy to vote all such shares in accordance with the terms of the voting agreement. For each of our directors and officers party to the voting agreement, the voting obligations contained in the agreement continue from and after, and for so long as, TMS’ director designation rights

are in effect, as described above, and such director or officer continues to serve in such capacity for our Company and continues to hold shares of our common stock.
Pursuant to the Purchase Agreement, we also entered into a registration rights agreement with TMS on June 13, 2018. Pursuant to the registration rights agreement, we became obligated to, at our expense, (1) file one or more registration statements with the SEC to cover the resale of the shares of our common stock purchased by TMS under the Purchase Agreement, (2) use our commercially reasonable efforts to cause all such registration statements to be declared effective in a timely manner, (3) use our commercially reasonable efforts to maintain the effectiveness of such registration statements until all such shares are sold or may be sold without restriction pursuant to applicable rules under the Securities Act, and (4) make and keep available adequate current public information and timely file with the SEC all required reports and other documents until all such shares are sold or may be sold without restriction. If such registration statements are not filed or declared effective as described above or any such effective registration statements subsequently become unavailable for more than 30 days in any 12-month period while they are required to be maintained as effective, then we would be required to pay liquidated damages to TMS equal to 0.75% of the aggregate purchase price for the shares remaining eligible for such registration rights each month for each such failure (up to a maximum of 4.0% of the aggregate purchase price for the shares remaining eligible for such registration rights each year).
Credit Support Agreement
On January 2, 2019, we entered a credit support agreement (as amended, the “CSA”) with TotalEnergies Holdings USA Inc. (“THUSA”), a wholly owned subsidiary of TotalEnergies. Under the CSA, THUSA agreed to enter into a guaranty agreement (“Guaranty”) pursuant to which it has guaranteed our obligation to repay up to $100.0 million in term loans (“Loans”) and interest thereon in accordance with a term credit agreement we have entered into with an unaffiliated third party (the “Lender”). In consideration for the commitments of THUSA under the CSA, we are required to pay THUSA a quarterly guaranty fee at a rate per quarter equal to 2.5% of the average aggregate Loan amount for the preceding calendar quarter.
Following any payment by THUSA to the Lender under the Guaranty, we would be obligated to immediately pay to THUSA the full amount of such payment plus interest on such amount at a rate equal to LIBOR plus 1.0%. In addition, we would be obligated to pay and reimburse THUSA for all reasonable out-of-pocket expenses it incurs in the performance of its services under the CSA, including all reasonable out-of-pocket attorneys’ fees and expenses incurred in connection with the payment to the Lender under the Guaranty or any enforcement or attempt to enforce any of our obligations under the CSA.
The CSA includes customary representations and warranties and affirmative and negative covenants by us. In addition, upon the occurrence of a “Trigger Event” and during its continuation, THUSA may, among other things: elect not to guarantee additional Loans; declare all or any portion of the outstanding amounts we owe THUSA under the CSA to be due and payable; and exercise all other rights it may have under applicable law. Each of the following events constitutes a Trigger Event: we default with respect to any payment obligation under the CSA; any representation or warranty made by us in the CSA was false, incorrect, incomplete or misleading in any material respect when made; we fail to observe or perform any material covenant, obligation, condition or agreement in the CSA; or we default in the observance or performance of any agreement, term or condition contained in any other agreement with THUSA or an affiliate of THUSA.
As security for our obligations under the CSA, on January 2, 2019, we entered into a pledge and security agreement with THUSA and delivered a collateral assignment of contracts to THUSA, pursuant to which we collaterally assigned to THUSA all fueling agreements we enter into with participants in our Zero Now truck financing program. In addition, on January 2, 2019, we entered into a lockbox agreement with THUSA and PlainsCapital Bank, under which we granted THUSA a security interest in the cash flow generated by the fueling agreements we enter into with participants in the Zero Now program. Until the occurrence of a Trigger Event or Fundamental Trigger Event (as described below) under the CSA, we have the freedom to operate in the normal course and there are no restrictions on the flow of funds in and out of the lockbox account established pursuant to the lockbox agreement. Upon the occurrence of a Trigger Event under the CSA, all funds in the lockbox account will be: first, used to make scheduled debt repayments of Loans and interest thereon; and second, released to us. Further, upon the occurrence of a “Fundamental

TABLE OF CONTENTS

Trigger Event” under the CSA and during its continuation, in addition to exercising any of the remedies available to THUSA upon the occurrence of a Trigger Event as described above: all participants in the Zero Now program would pay amounts owed under their fueling agreements with us directly into the lockbox account; under a “sweep” mechanism, all cash in the lockbox account would be used to prepay all outstanding Loans; no other disbursements from the lockbox account could be made without THUSA’s consent; and THUSA would retain dominion over the lockbox account and the funds in the account would remain as security for our payment and reimbursement obligations under the CSA. Each of the following events constitutes a Fundamental Trigger Event: we default in the observance or performance of any agreement, term or condition contained in the term credit agreement governing the Loans that would constitute an event of default thereunder, up to or beyond any grace period provided in such agreement, unless waived by the Lender; we default in the observance or performance of any agreement, term or condition contained in any evidence of indebtedness other than such term credit agreement, and the effect of such default is to cause, or permit the holders of such indebtedness to cause, acceleration of indebtedness in an aggregate amount for all such collective defaults of $20.0 million or more; voluntary and involuntary bankruptcy and insolvency events; and the occurrence of a change of control of our Company.
The CSA will terminate following the later of: the payment in full of all of our obligations under the CSA; and the termination or expiration of the Guaranty following the maturity date of the last outstanding Loan or December 31, 2023, whichever is earlier.
During 2021, we paid TotalEnergies $0.3 million related to the guaranty fee under the CSA.
Commodity Swap Arrangements
In October 2018, we entered into commodity swap arrangements with TotalEnergies Gas & Power North America, an affiliate of TotalEnergies and THUSA,TotalEnergies Holdings USA Inc. (“THUSA”), intended to manage diesel price fluctuation risks related to the natural gas fuel supply commitments we expect to make in our anticipated fueling agreements with fleet operators that participate in our Zero Now truck financing program, which arrangements cover five million diesel gallons of natural gas fuel volume annually from April 2019 through June 2024. During the year ended December 31, 2021,2023, the Company paid TotalEnergies Gas & Power North America $0.8$6.3 million for settlements on commodity swap contracts and recognized revenue of $0.2$1.4 million related to settlements on commodity swap contracts.

Exercise of the Option shall occur as provided in Section 8, unless the Participant has withdrawn pursuant to Section 10, and the Option, to the extent not exercised, shall expire on the last day of the Offer Period with respect to which such Option was granted. Notwithstanding the foregoing, shares subject to the Option may only be purchased with accumulated payroll deductions credited to a Participant’s account in accordance with Section 6. In addition, to the extent an Option is not exercised on the Exercise Date, the Option shall lapse and thereafter cease to be exercisable.
8.   Exercise of Option.   Unless a Participant withdraws from the Plan as provided in Section 10, the Participant’s Option for the purchase of shares of Common Stock will be exercised automatically on the Exercise Date, by applying the accumulated payroll deductions in the Participant’s account to purchase the number of full shares subject to the Option by dividing such Participant’s payroll deductions accumulated prior to the Exercise Date and retained in the Participant’s account as of the Exercise Date by the applicable Purchase Price.

In the event the Company is required to file a registration statement to issue any such certificate or otherwise deliver such shares, the Company will seek to obtain such authority. If the Company is unable to obtain from any such commission or agency authority which counsel for the Company deems necessary for the lawful issuance of any such certificate or other delivery of such shares, or if for any other reason the Corporation cannot issue or deliver shares of Common Stock and comply with Applicable Laws, the Corporation shall be relieved from liability to any Participant except that the Company shall return to each Participant to whom such shares cannot be issued or delivered the amount of the balance credited to his or her account that would have otherwise been used for the purchase of such shares.
10.   Withdrawal; Termination of Employment.
(a)   A Participant may, by giving notice to the Company (using such form or method (including electronic forms) as the Administrator may designate from time to time), either: (i) withdraw all but not less than all the payroll deductions credited to the Participant’s account and not yet used to exercise the Participant’s Option under the Plan; or (ii) terminate future payroll deductions, but allow accumulated payroll deductions to be used to exercise the Participant’s Option under the Plan at any time. If the Participant elects withdrawal alternative (i) described above, all of the Participant’s payroll deductions credited to the Participant’s account will be paid to such Participant as soon as administratively practicable after receipt of notice of withdrawal, such Participant’s Option for the Offer Period will be automatically terminated, and no further payroll deductions for the purchase of shares will be made during the Offer Period. If the Participant elects withdrawal alternative (ii) described above, no further payroll deductions for the purchase of shares will be made during the Offer Period, all of the Participant’s payroll deductions credited to the Participant’s account will be applied to the exercise of the Participant’s Option on the Exercise Date (subject to Sections 3(b), 6, 7 and 12), and all remaining accumulated payroll deduction amounts shall be returned to the Participant.

from an Offer Period, payroll deductions will not resume at the beginning of the succeeding Offer Period unless the Participant enrolls in such succeeding Offer Period as provided in Section 10(b). The Administrator may, in its discretion and on a uniform and nondiscriminatory basis, specify procedures for withdrawal.
(b)   A Participant’s termination from Plan participation during the Offer Period precludes the Participant from again participating in this Plan during that Offer Period. However, such termination shall not have any effect upon his or her ability to participate in any succeeding Offer Period, provided that the applicable eligibility and participation requirements are again then met. A Participant’s termination from Plan participation shall be deemed to be a revocation of that Participant’s authorization of payroll deduction and such Participant must submit a new authorization of payroll deduction (using such form or method (including electronic forms) as the Administrator may designate from time to time) to resume Plan participation in any succeeding Offer Period.
(c)   Upon termination of a Participant’s employment relationship (as described in Section 2(l)) prior to the Exercise Date, the payroll deductions credited to such Participant’s account during the Offer Period will be returned to such Participant or, in the case of his/her death, to the person or persons entitled thereto under Section 14, and such Participant’s Option will be automatically terminated without exercise of any portion of such Option.
(d)   For purposes of this Plan, if a Designated Parent or Subsidiary ceases to be a Designated Parent or Subsidiary, each person employed by such Designated Parent or Subsidiary will be deemed to have terminated employment for purposes of this Plan and will no longer be an eligible Employee under the Plan, unless such person continues as an eligible Employee in respect of the Company or another Designated Parent or Subsidiary.

(a)   The maximum number of shares of Common Stock which shall be made available for sale under the Plan shall be two million five hundred thousand shares (2,500,000) shares, subject to adjustment upon changes in capitalization of the Company as provided in Section 18. If the Administrator determines that on the Exercise Date for an Offer Period the number of shares with respect to which Options are to be exercised exceeds: (x) the number of shares then available for sale under the Plan; or (y) the number of shares available for sale under the Plan on the Offering Date for such Offer Period, the Administrator may disallow the purchase of any shares, and may make a pro rata allocation of the shares remaining available for purchase on such Offering Date or Exercise Date, as applicable, and shall either continue the Offer Period then in effect or terminate the Offer Period then in effect pursuant to Section 19, below. Such allocation method shall be “bottom up,” with the result that all Option exercises for one share shall be satisfied first, followed by all exercises for two shares, and so on, until all available shares have been exhausted. Any amount remaining in a Participant’s payroll account following such pro rata allocation shall be returned to the Participant and shall not be carried over to any Offer Period, as determined by the Administrator.
(b)   A Participant will have no interest in or voting right with respect to shares covered by the Participant’s Option until such shares are purchased on the Participant’s behalf on the exercise date in accordance with the applicable provisions of the Plan. No adjustment shall be made for dividends, distributions or other rights for which the record date is prior to the date of such purchase.

take the Full Value Award ratio below into account, each share subject to any such award shall be credited as 1.5 shares when determining the number of shares that shall become available for new awards under this Plan,
provided that in no event shall the Share Limit exceed 24,675,720 shares (which is the sum of the 4,000,000 shares set forth above, plus the number of shares available under the 2016 Plan for additional award grant purposes as of the Effective Date defined below, plus the aggregate number of shares subject to awards previously granted and outstanding under the 2006 Plan and the 2016 Plan as of the Effective Date, with any shares subject to restricted stock and restricted stock unit awards outstanding under the 2006 Plan and the 2016 Plan being taken into account based on the Full-Value Award share counting ratio of 1.5).
Shares issued in respect of any “Full-Value Award” granted under this Plan shall be counted against the foregoing Share Limit as 1.5 shares for every one share issued in connection with such award. (For example, if a designation (using such formstock bonus of 100 shares of Common Stock is granted under this Plan, 150 shares shall be counted against the Share Limit in connection with that award.) For this purpose, a “Full-Value Award” means any award under this Plan that is not a stock option grant or method (including electronic forms)a stock appreciation right grant.
The following limits also apply with respect to awards granted under this Plan:
(e)
The maximum number of shares of Common Stock that may be delivered pursuant to options qualified as incentive stock options granted under this Plan is 4,000,000 shares.
(f)
Awards that are granted under this Plan during any one calendar year to any person who, on the grant date of the award, is a non-employee director are subject to the limits of this Section 4.2(f). The maximum number of shares of Common Stock subject to those awards that are granted under this Plan during any one calendar year to an individual who, on the grant date of the award, is a non-employee director is the number of shares that produce a grant date fair value for the award that, when combined with the grant date fair value of any other awards granted under this Plan during that same calendar year to that individual in his or her capacity as a non-employee director, is $400,000; provided that this limit is $600,000 as to (1) a non-employee director who is serving as the Independent Chair of the Board or the Lead Independent Director at the time the applicable grant is made or (2) any new non-employee director for the calendar year in which the non-employee director is first elected or appointed to the Board. For purposes of this Section 4.2(f), a “non-employee director” is an individual who, on the grant date of the award, is a member of the Board who is not then an officer or employee of the Corporation or one of its Subsidiaries. For purposes of this Section 4.2(f), “grant date fair value” means the value of the award as of the date of grant of the award and as determined using the equity award valuation principles applied in the Corporation’s financial reporting. The limits of this Section 4.2(f) do not apply to, and shall be determined without taking into account, any award granted to an individual who, on the grant date of the award, is an officer or employee of the Corporation or one of its subsidiaries. The limits of this Section 4.2(f) apply on an individual basis and not on an aggregate basis to all non-employee directors as a group.
Each of the foregoing numerical limits is subject to adjustment as contemplated by Section 4.3, Section 7.1, and Section 8.10.
4.3Awards Settled in Cash, Reissue of Awards and Shares.   Except as provided in the next sentence, shares that are subject to or underlie awards granted under this Plan which expire or for any reason are cancelled or terminated, are forfeited, fail to vest, or for any other reason are not paid or delivered under this Plan shall not be counted against the Share Limit and shall be available for subsequent awards under this Plan. Shares that are exchanged by a participant or withheld by the Corporation as full or partial payment in connection with any award under this Plan, as well as any shares exchanged by a participant or withheld by the Corporation or one of its Subsidiaries to satisfy the tax withholding obligations related to any award, shall be counted against the Share Limit and shall not be available for subsequent awards under this Plan. Any shares of Common Stock repurchased with the proceeds of any option exercise price shall not be available for awards under this Plan. To the extent that shares of Common Stock are delivered pursuant to the exercise

A-4

TABLE OF CONTENTS

of a stock appreciation right granted under this Plan, the number of underlying shares as to which the exercise related shall be counted against the Share Limit. (For purposes of clarity, if a stock appreciation right relates to 100,000 shares and is exercised at a time when the payment due to the participant is 15,000 shares, 100,000 shares shall be counted against the Share Limit with respect to such exercise. To the extent that an award granted under this Plan is settled in cash or a form other than shares of Common Stock, the shares that would have been delivered had there been no such cash or other settlement shall not be counted against the Share Limit and shall be available for subsequent awards under this Plan. In the event that shares of Common Stock are delivered in respect of a dividend equivalent right granted under this Plan, the number of shares delivered with respect to the award shall be counted against the Share Limit. (For purposes of clarity, if 1,000 dividend equivalent rights are granted and outstanding when the Corporation pays a dividend, and 50 shares are delivered in payment of those rights with respect to that dividend, 75 shares (after giving effect to the Full-Value Award premium counting rules) shall be counted against the Share Limit). The Company may not increase the Share Limits by repurchasing shares of Common Stock on the market (by using cash received through the exercise of stock options or otherwise). Refer to Section 8.10 for application of the foregoing share limits with respect to assumed awards.
4.4No Fractional Shares; Minimum Issue.   Unless otherwise expressly provided by the Administrator, no fractional shares shall be delivered under this Plan. The Administrator may designatepay cash in lieu of any fractional shares in settlements of awards under this Plan. The Administrator may from time to time)time impose a limit (of not greater than 100 shares) on the minimum number of shares that may be purchased or exercised as to awards (or any particular award) granted under this Plan unless (as to any particular award) the total number purchased or exercised is the total number at the time available for purchase or exercise under the award.
5.

The types of awards that may be granted under this Plan are (subject, in each case, to the no repricing provisions of Section 3.2):
(a)
Stock Options.   A stock option is the grant of a beneficiary whoright to purchase a specified number of shares of Common Stock during a specified period as determined by the Administrator. An option may be intended as an incentive stock option within the meaning of Section 422 of the Code (an “ISO”) or a nonqualified stock option (an option not intended to be an ISO). The award agreement for an option will indicate if the option is intended as an ISO; otherwise it will be deemed to receive any shares and cash, if any, from the Participant’s account under the Plan in the eventbe a nonqualified stock option. The maximum term of such Participant’s death. If a Participant is married and the designated beneficiary is not the spouse, spousal consenteach option (ISO or nonqualified) shall be requiredten (10) years. The per share exercise price for such designationeach option shall be not less than 100% of the fair market value of a share of Common Stock on the date of grant of the option.

(b)
Additional Rules Applicable to ISOs.   To the event ofextent that the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is livingaggregate fair market value (determined at the time of such Participant’s death,grant of the Company shall deliver such shares and/applicable option) of stock with respect to which ISOs first become exercisable by a participant in any calendar year exceeds $100,000, taking into account both Common Stock subject to ISOs under this Plan and stock subject to ISOs under all other plans of the Corporation or cashone of its Subsidiaries (or any parent or predecessor corporation to the executor or administratorextent required by and within the meaning of Section 422 of the estateCode and the regulations promulgated thereunder), such options shall be treated as nonqualified stock options. In reducing the number of options treated as ISOs to meet the Participant, or if no such executor or administrator has been appointed (to$100,000 limit, the knowledgemost recently granted options shall be reduced first. To the extent a reduction of simultaneously granted options is necessary to meet the Administrator),$100,000 limit, the Administrator shall deliver such shares and/or cashmay, in the manner and to the spouse (or domestic partner, as determinedextent permitted by the Administrator)law, designate which shares of the Participant, or if no spouse (or domestic partner) is known to the Administrator, then to the issue of the Participant, such distributionCommon Stock are to be made per stirpes (by right of representation), or if no issue are known to the Administrator, then to the heirs at law of the Participant determined in accordance with Section 27.
15.   Transferability.   No payroll deductions credited to a Participant’s account, Options granted hereunder, or any rights with regardtreated as shares acquired pursuant to the exercise of an OptionISO.

A-5

TABLE OF CONTENTS

of the Code, which generally requires an unbroken chain of ownership of at least 50% of the total combined voting power of all classes of stock of each subsidiary in the chain beginning with the Corporation and ending with the subsidiary in question). No ISO may be granted to any person who, at the time the option is granted, owns (or is deemed to own under Section 424(d) of the Code) shares of outstanding Common Stock possessing more than 10% of the total combined voting power of all classes of stock of the Corporation, unless the exercise price of such option is at least 110% of the fair market value of the stock subject to the option and such option by its terms is not exercisable after the expiration of five years from the date such option is granted. If an otherwise-intended ISO fails to meet the applicable requirements of Section 422 of the Code, the option shall be a nonqualified stock option.
(c)
Stock Appreciation Rights.   A stock appreciation right or “SAR” is a right to receive a payment, in cash and/or Common Stock, equal to the excess of the fair market value of a specified number of shares underof Common Stock on the Plandate the SAR is exercised over the “base price” of the award, which base price shall be set forth in the applicable award agreement and shall be not less than 100% of the fair market value of a share of Common Stock on the date of grant of the SAR. The maximum term of a SAR shall be ten (10) years.
(d)
Other Awards; Dividend Equivalent Rights.   The other types of awards that may be assigned, transferred, pledgedgranted under this Plan include: (a) stock bonuses, restricted stock, performance stock, stock units, phantom stock or similar rights to purchase or acquire shares, whether at a fixed or variable price (or no price) or fixed or variable ratio related to the Common Stock, and any of which may vest upon the passage of time, the occurrence of one or more events, the satisfaction of performance criteria or other conditions, or any combination thereof; or (b) cash awards. The types of cash awards that may be granted under this Plan include the opportunity to receive a payment for the achievement of one or more goals established by the Administrator, on such terms as the Administrator may provide, as well as cash awards. Dividend equivalent rights may be granted as a separate award or in connection with another award under this Plan; provided, however, that dividend equivalent rights may not be granted as to a stock option or SAR granted under this Plan. In addition, any dividends and/or dividend equivalents as to the unvested portion of a restricted stock award that is subject to vesting requirements or the unvested portion of a stock unit award that is subject to vesting requirements will be subject to termination and forfeiture to the same extent as the corresponding portion of the award to which they relate in the event the applicable vesting requirements are not satisfied. In addition, any dividends and/or dividend equivalents as to the portion of an award that is subject to unsatisfied vesting requirements will be subject to termination and forfeiture to the same extent as the corresponding portion of the award to which they relate in the event the applicable vesting requirements are not satisfied. This ensures that if the underlying unvested award is forfeited, the dividends and/or dividend equivalents on the unvested awards will also be forfeited.
5.2Award Agreements.   Each award shall be evidenced by a written or electronic award agreement or notice in a form approved by the Administrator (an “award agreement”), and, in each case and if required by the Administrator, executed or otherwise disposedelectronically accepted by the recipient of the award in such form and manner as the Administrator may require.
5.3Deferrals and Settlements.   Payment of awards may be in the form of cash, Common Stock, other awards or combinations thereof as the Administrator shall determine, and with such restrictions (if any) as it may impose. The Administrator may also require or permit participants to elect to defer the issuance of shares or the settlement of awards in cash under such rules and procedures as it may establish under this Plan. The Administrator may also provide that deferred settlements include the payment or crediting of interest or other earnings on the deferral amounts, or the payment or crediting of dividend equivalents where the deferred amounts are denominated in shares.
5.4Consideration for Common Stock or Awards.   The purchase price (if any) for any award granted under this Plan or the Common Stock to be delivered pursuant to an award, as applicable, may be paid by means of any lawful consideration as determined by the Administrator, including, without limitation, one or a combination of the following methods:

services rendered by the recipient of such award;
(b)
cash, check payable to the order of the Corporation, or electronic funds transfer;
(c)
notice and third-party payment in such manner as may be authorized by the Administrator;
(d)
the delivery of previously owned shares of Common Stock;
(e)
by a reduction in the number of shares otherwise deliverable pursuant to the award; or
(f)
subject to such procedures as the Administrator may adopt, pursuant to a “cashless exercise” with a third party who provides financing for the purposes of (or who otherwise facilitates) the purchase or exercise of awards.
In no event shall any shares newly-issued by the Corporation be issued for less than the minimum lawful consideration for such shares or for consideration other than consideration permitted by applicable state law. The Corporation will not be obligated to deliver any shares unless and until it receives full payment of the exercise or purchase price therefor and any related withholding obligations under Section 8.5 and any other conditions to exercise or purchase have been satisfied. Unless otherwise expressly provided in the applicable award agreement, the Administrator may at any time eliminate or limit a participant’s ability to pay any purchase or exercise price of any award or shares by any method other than cash payment to the Corporation.
5.5Definition of Fair Market Value.   For purposes of this Plan, “fair market value” shall mean, unless otherwise determined or provided by the Administrator in the circumstances, the closing price (in regular trading) for a share of Common Stock on the NASDAQ Stock Market (the “Market”) for the date in question or, if no sales of Common Stock were reported on the Market on that date, the closing price (in regular trading) for a share of Common Stock on the Market for the next preceding day on which sales of Common Stock were reported on the Market. The Administrator may, however, provide with respect to one or more awards that the fair market value shall equal the closing price (in regular trading) for a share of Common Stock on the Market on the last trading day preceding the date in question or the average of the high and low trading prices of a share of Common Stock on the Market for the date in question or the most recent trading day. If the Common Stock is no longer listed or is no longer actively traded on the Market as of the applicable date, the fair market value of the Common Stock shall be the value as reasonably determined by the Administrator for purposes of the award in the circumstances. The Administrator also may adopt a different methodology for determining fair market value with respect to one or more awards if a different methodology is necessary or advisable to secure any intended favorable tax, legal or other treatment for the particular award(s) (for example, and without limitation, the Administrator may provide that fair market value for purposes of one or more awards will be based on an average of closing prices (or the average of high and low daily trading prices) for a specified period preceding the relevant date).
5.6Transfer Restrictions.
(a)
Limitations on Exercise and Transfer.   Unless otherwise expressly provided in (or pursuant to) this Section 5.6 or required by applicable law: (a) all awards are non-transferable and shall not be subject in any way (other than by will, the laws of descent and distribution,manner to sale, transfer, anticipation, alienation, assignment, pledge, encumbrance or as provided in Section 14)charge; (b) awards shall be exercised only by the Participant.

(e)   In any of such events, the Administrator may take such action sufficiently prior to such event to the extent that the Administrator deems the action necessary to permit the Participant to realize the benefits intended to be conveyed with respect to the underlying shares in the same manner as is or will be available to stockholders generally.

To the extent necessary to comply with Section 423 of the Code (or any successor rule or provision or any other Applicable Law), the Company shall obtain stockholder approval of any amendment in such a manner and to such a degree as required.
(b)   Without stockholder consent and without regard to whether any Participant rights may be considered to have been “adversely affected,” the Administrator shall be entitled to limit the frequency and/or number of changes in the amount withheld during Offer Periods, determine the length of any future Offer Period and frequency of purchases within each Offer Period, determine whether future Offer Periods shall be consecutive or overlapping, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, establish or change Plan or per Participant limits on share purchases, designate from time to time the Parents and/or Subsidiaries whose employees may be eligible to participate in the Plan, change the service and other qualification requirements for eligible Employees under the Plan (subject to the requirements of Section 423(b) of the Code and applicable rules and regulations thereunder), establish additional terms, conditions, rules or procedures to accommodate the rules or laws of applicable foreign jurisdictions, permit payroll withholding in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed withholding elections, establish reasonable waiting and adjustment periods and/or accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with amounts withheld from the Participant’s Compensation, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable and which are consistent with the Plan, in each case to the extent consistent with the requirements of Code Section 423 and other Applicable Laws.
20.   Notices.
(a)   All notices or other communications by a Participant to the Company under or in connection with the Plan7.2, an award shall be deemed to have been duly given when“assumed” if (without limiting other circumstances in which an award is assumed) the award continues after the applicable event, and/or is assumed and continued by the surviving entity following such event (including, without limitation, an entity that, as a result of such event, owns the Corporation or all or substantially all of the Corporation’s assets directly or through one or more subsidiaries (a “Parent”)), and confers the right to purchase or receive, as applicable and subject to vesting and the other terms and conditions of the award, for each share of Common Stock subject to the award immediately prior to the event, the consideration (whether cash, shares, or other securities or property) received in the form specifiedevent by the stockholders of the Corporation for each share of Common Stock sold or exchanged in such event (or the consideration received by a majority of the stockholders participating in such event if the stockholders were offered a choice of consideration); provided, however, that if the consideration offered for a share of Common Stock in the event is not solely the ordinary common stock of a successor corporation or a Parent, the Administrator may provide for the consideration to be received upon exercise or payment of the award, for each share subject to the award, to be solely ordinary common stock of the successor corporation or a Parent equal in fair market value to the per share consideration received by the stockholders participating in the event.
(d)
The Administrator may adopt such valuation methodologies for outstanding awards as it deems reasonable in the event of a cash or property settlement and, in the case of options, SARs or similar rights, but without limitation on other methodologies, may base such settlement solely upon the excess if any of the per share amount payable upon or in respect of such event over the exercise or base price of the award. In the case of an option, SAR or similar right as to which the per share amount payable upon or in respect of such event is less than or equal to the exercise or base price of the award, the Administrator may terminate such award in connection with an event referred to in this Section 7.2 without any payment in respect of such award.
(e)
In any of the events referred to in this Section 7.2, the Administrator may take such action contemplated by this Section 7.2 prior to such event (as opposed to on the occurrence of such event) to the extent that the Administrator deems the action necessary to permit the participant to realize the benefits intended to be conveyed with respect to the underlying shares. Without limiting the generality of the foregoing, the Administrator may deem an acceleration and/or termination to occur immediately prior to the applicable event and, in such circumstances, will reinstate the original terms of the award if an event giving rise to an acceleration and/or termination does not occur.
(f)
Without limiting the generality of Section 3.3, any good faith determination by the Administrator atpursuant to its authority under this Section 7.2 shall be conclusive and binding on all persons.
7.3Other Acceleration Rules.   The Administrator may override the location,provisions of Section 7.2 by express provision in the award agreement and may accord any Eligible Person a right to refuse any acceleration, whether pursuant to the award agreement or by the person, designated byotherwise, in such circumstances as the Administrator formay approve. The portion of any ISO accelerated in connection with an event referred to in

Neither the provisions of this Plan (or of any related documents), nor the creation or adoption of this Plan, nor any action taken pursuant to the provisions of this Plan shall create, or be construed to create, a trust of any kind or a fiduciary relationship between the Corporation or one of its Subsidiaries and any participant, beneficiary or other person. To the extent that a participant, beneficiary or other person acquires a right to receive payment pursuant to any award hereunder, such right shall be no greater than the right of any unsecured general creditor of the Corporation.
