We are pleased to utilize the Securities and Exchange Commission, or SEC, rules that allow issuers to furnish proxy materials to their stockholders on the Internet. On or about April 24, 2026, we will mail to our stockholders of record as of April 10, 2026 (other than those who previously requested electronic or paper delivery on an ongoing basis) a Notice Regarding the Availability of Proxy Materials, or Notice, with instructions for accessing the proxy materials and voting over the Internet, by telephone or mobile device or by mail. The Notice also provides information on how stockholders may request paper copies of our proxy materials. We believe electronic delivery of our proxy materials and our 2025 Annual Report will help us reduce the environmental impact and costs of printing and distributing paper copies and improve the speed and efficiency by which our stockholders can access these materials.
By Order of the Board of Directors,
April 23, 2026

GENERAL INFORMATION ABOUT THE MEETING AND VOTING
This proxy statement is furnished in connection with the solicitation of proxies by the board of directors of Ameresco, Inc. for use at the 2026 annual meeting of stockholders, or the Annual Meeting, to be held on June 4, 2026, at 10:00 a.m., local time, and at any adjournments of the Annual Meeting. We will hold our annual meeting of stockholders in virtual meeting, via live audio webcast. You may virtually attend the meeting and vote your shares by visiting https://www.virtualshareholdermeeting.com/AMRC2026.
In this proxy statement, unless expressly stated or the context otherwise requires, the use of "Ameresco," "our company," "our," "we," or "us" refers to Ameresco, Inc.
We are mailing the Notice Regarding the Availability of Proxy Materials, or the Notice, to our stockholders of record as of April 10, 2026, or the Record Date, on or about April 24, 2026. In addition, we have provided brokers, dealers, banks, voting trustees and their nominees, at our expense, with additional copies of our proxy materials and the 2025 Annual Report so that our record holders can supply these materials to the beneficial owners of shares of our Class A common stock and Class B common stock as of the Record Date. The proxy statement and our annual report to stockholders are available for viewing, printing and downloading online at the "Investor Relations - Annual Meeting" section of our website at https://www.ameresco.com.
Information about the proxy process and voting Record Date, Voting Rights and Outstanding Shares
Our board of directors has fixed April 10, 2026 as the record date for determining the holders of our capital stock who are entitled to vote at the annual meeting.
We have two classes of capital stock issued and outstanding: Class A common stock, $.0001 par value per share, and Class B common stock, $.0001 par value per share. We refer to our Class A common stock and our Class B common stock collectively as our common stock.
With respect to all of the matters submitted for vote at the Annual Meeting, each share of Class A common stock is entitled to one vote and each share of Class B common stock is entitled to five votes.
Our Class A common stock and Class B common stock will vote as a single class on each of the matters submitted at the Annual Meeting. On April 10, 2026, there were outstanding and entitled to vote 34,939,417 shares of Class A common stock and 18,000,000 shares of Class B common stock.
In order for business to be conducted at the Annual Meeting, a quorum must be present at the meeting. A quorum for purposes of the Annual Meeting will exist if the holders of a majority of the voting power represented by the common stock issued and outstanding on April 10, 2026 attend the virtual meeting or are represented by proxy at the Annual Meeting. Shares represented by valid proxies, regardless of whether the proxy is noted as casting a vote or abstaining, and broker non-votes (described below) will be treated as present at the Annual Meeting for purposes of determining a quorum. Shares voted by a broker on any item other than a procedural motion will be considered present for purposes of determining a quorum, even if such shares are not voted on every item.
Election of directors (Proposal 1): The two director nominees identified in this proxy statement receiving a plurality, or the highest number, of votes cast, regardless of whether that number represents a majority of the votes cast, will be elected.
Only votes "For" will affect the outcome of this proposal.
Ratification of the appointment of RSM US LLP (Proposal 2): The affirmative vote of a majority of the votes cast is needed to ratify the appointment of RSM US LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2026. Abstentions and broker non-votes will have no effect on the outcome of this proposal.
Approval of an amendment to our 2020 Equity Incentive Plan (Proposal 3): The affirmative vote of the holders of shares of capital stock representing a majority of our outstanding shares of capital stock entitled to vote thereon is required to approve the amendment to the 2020 Equity Incentive Plan. Abstentions and broker non-votes will have the same effect as a vote cast "AGAINST" the proposal. If you do not instruct your broker, bank or other nominee how to vote on this proposal, we anticipate that brokers will not have discretionary authority to vote your shares with respect to this proposal.
Advisory vote on executive compensation (Proposal 4): The affirmative vote of the majority of votes cast is required for approval. Abstentions and broker non-votes will have no effect on the outcome of this proposal. As an advisory vote, this proposal is not binding. However, our board and compensation committee will review the voting results and take them into consideration when making future decisions regarding our executive compensation programs.
Stockholders of Record. If on the Record Date, your shares were registered directly in your name with the transfer agent for our common stock, then you are a stockholder of record. As a stockholder of record, you may vote at the Annual Meeting or by proxy. Whether or not you plan to attend the Annual Meeting, we urge you to vote and submit your proxy in advance of the Annual Meeting by one of the methods below to ensure your vote is counted. To vote by any of these methods, read this Proxy Statement, have your Notice, proxy card, or voting instruction form in hand, and follow the instructions below for your preferred method of voting. Each of these voting methods is available 24 hours per day, seven days per week, but you must vote by 11:59 pm. on June 3, 2026.

Beneficial Owner (Shares Registered in the Name of a Broker, Bank or Other Agent). If, on the Record Date, your shares were held in an account at a broker, bank or other agent, then you are the beneficial owner of shares held in "street name" and the Notice or these proxy materials are being forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct your broker, bank or other agent on how to vote the shares in your account. You are also invited to attend the Annual Meeting via the Internet. However, because you are not the stockholder of record, you may not vote your shares at the Annual Meeting unless you request and obtain a valid proxy card from your broker, bank or other agent.
Please follow the instructions from your broker, bank or other agent included with these proxy materials, or contact your broker, bank or other agent to request a proxy card.
Broker non-votes occur when a beneficial owner of shares held in "street name" does not give instructions to the broker, bank or other agent holding the shares as to how to vote on matters deemed "non-discretionary." Generally, if shares are held in street name, the beneficial owner of the shares is entitled to give voting instructions to the broker, bank or other agent holding the shares. If the beneficial owner does not provide voting instructions, the broker, bank or other agent can still vote the shares with respect to matters that are considered to be "discretionary," but not with respect to "non-discretionary" matters. In the event that a broker, bank or other agent or other record holder of common stock indicates on a proxy that it does not have discretionary authority to vote certain shares on a particular proposal, then those shares will be treated as broker non-votes with respect to that proposal. Accordingly, if you own shares through a nominee, such as a broker, bank or other agent, please be sure to instruct your nominee how to vote to ensure that your vote is counted on each of the proposals.
The ratification of the appointment of RSM LLP as our independent registered public accounting firm for the year ending December 31, 2026 (Proposal 2) is considered discretionary under applicable rules. A broker, bank or other agent may generally vote on discretionary matters, and therefore no broker non-votes are expected to exist in connection with Proposal 2. The election of directors (Proposal 1), the 2020 Plan Amendment (Proposal 3), and the Adviosry Vote on Executive Compensation (Proposal 4) are considered non-discretionary under applicable rules. A broker, bank or other
agent cannot vote without instructions on non-discretionary matters, and therefore there may be broker non-votes on Proposal 1, Proposal 3 or Proposal 4.
We do not know of any other proposals that may be presented at the Annual Meeting. If another matter is properly presented for consideration at the meeting, the persons named in the accompanying proxy card will exercise their discretion in voting on the matter.
Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting. If you are the record holder of your shares, you may revoke your proxy in any one of three (3) ways:
You may submit another properly completed proxy with a later date over the Internet, by telephone or mobile device or by mail.
You may send a written notice that you are revoking your proxy to us at our principal executive offices, 111 Speen Street, Suite 410, Framingham, Massachusetts 01701, Attention: Secretary.
You may attend the Annual Meeting via the Internet and vote online. Simply attending the Annual Meeting will not, by itself, revoke your proxy.
If your shares are held by your broker, bank or other agent, you should follow the instructions provided by them.
We will report the voting results from the Annual Meeting in a Current Report on Form 8-K, which we expect to file with the SEC within four business days after the Annual Meeting.
If you receive more than one Notice, your shares are registered in more than one name or are registered in different accounts. In order to vote all the shares you own, you must vote pursuant to the instructions on each Notice.
We will bear the costs of soliciting proxies. We will, upon request, reimburse brokers, custodians and fiduciaries for reasonable out-of-pocket expenses incurred in forwarding proxy solicitation materials to the beneficial owners of stock held in their names. In addition to solicitations by mail, our directors, officers and employees may solicit proxies from stockholders in person or by other means of communication, including telephone, facsimile and e-mail, without additional remuneration.
PROPOSAL 1-ELECTION OF DIRECTORS
Our board of directors is divided into three classes, with one class being elected each year and members of each class holding office for a three-year term. We have three (3) class I directors, whose terms expire at this annual meeting of stockholders; three (3) class II directors, whose terms expire at our 2027 annual meeting of stockholders; and two (2) class III directors, whose terms expire at our 2028 annual meeting of stockholders. following the Annual Meeting would consist of seven members.
At this Annual Meeting, our stockholders will have an opportunity to vote for two (2) nominees for class I directors:
Claire Hughes-Johnson and
Frank V. Wisneski
each of whom are currently directors of Ameresco. Charles R. Patton., will not be standing for re-election as a Class I director at the Annual Meeting. Our board of directors currently consists of eight members, and following the Annual Meeting subject to approval of this proposal, our board of directors will consist of seven members. You can find more information about each of the nominees in "Corporate Governance-Our Board of Directors" below.
If no contrary indication is made, proxies in the accompanying form will be voted "FOR" these two nominees as class I directors. If elected, each of the nominees for class I director will hold office until the 2029 annual meeting of stockholders and until their successor is elected and qualified or until their earlier death, resignation or removal. Each of the nominees has indicated their willingness to serve if elected. However, if any nominee should be unable to serve, then either the persons named in the proxy card may vote the proxy for a substitute nominee if one is nominated by our board of directors, or we may maintain a vacancy on our board of directors until such time as our board of directors can find a suitable candidate to serve on the board, or our board of directors may reduce the number of directors.
PROPOSAL 2-RATIFICATION OF THE SELECTION OF OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The audit committee of our board of directors has selected RSM US LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026. Although stockholder approval of our audit committee's selection of RSM US LLP is not required by law, we believe that it is advisable to give stockholders an opportunity to ratify this selection. If our stockholders do not ratify this selection, our audit committee will reconsider the selection. We expect that a representative of RSM US LLP will attend the virtual Annual Meeting and will be offered the opportunity to make a statement if they wish.

Policy on Pre-Approval of Audit and Non-Audit Services
Before an accountant is engaged by us to render audit or non-audit services, the engagement is approved by our audit committee. From time to time, our audit committee may pre-approve specified types of services that are expected to be provided to us by our registered public accounting firm during the next twelve (12) months. Any such pre-approval would be detailed as to the particular service or type of services to be provided and also generally would be subject to a maximum dollar amount.
Our audit committee may delegate the authority to approve any audit or non-audit services to be provided to us by our registered public accounting firm to one or more subcommittees (including a subcommittee consisting of a single member). Any approval of services by a subcommittee of our audit committee pursuant to this delegated authority is reported at the next meeting of our audit committee. The chairman of our audit committee has been delegated this authority.
Audit Committee Report
The audit committee has reviewed and discussed with our management our audited consolidated financial statements for the year ended December 31, 2025. The audit committee has also reviewed and discussed with RSM US LLP, our independent registered public accounting firm, our audited consolidated financial statements and the matters required by the applicable requirements of the Public Company Accounting Oversight Board and the SEC.
The audit committee has also received from RSM US LLP the written disclosures and the letter required by the applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant's communications with the audit committee concerning independence. The audit committee has discussed with RSM US LLP the matters disclosed in the letter and its independence with respect to Ameresco, including a review of audit and non-audit fees and services, and concluded that RSM US LLP is independent.
Based on its discussions with management and RSM US LLP, and its review of the representations and information referred to above provided by management and RSM US LLP, the audit committee recommended to the board of directors that Ameresco's audited consolidated financial statements be included in Ameresco's annual report on Form 10-K for the year ended December 31, 2025 for filing with the SEC.

PROPOSAL 4 - APPROVAL OF AMENDMENT TO THE AMERESCO, INC. 2020 STOCK INCENTIVE PLAN
We are asking stockholders to approve an amendment to the Ameresco, Inc. 2020 Stock Incentive Plan, or the 2020 Plan Amendment. The 2020 Plan Amendment amends the 2020 Stock Incentive Plan, or the Current Plan. We refer to the Current Plan, as amended by the 2020 Plan Amendment, as the Amended Plan. Our board of directors believes that our success depends, in large part, on our ability to maintain a competitive position by attracting, retaining and motivating key employees with experience and ability. We believe that our stock-based compensation programs are central to this objective. We and our board of directors understand that our equity compensation needs must be balanced against the dilutive effects of such programs on our stockholders. To that end, and based on careful weighing of these considerations, as more fully described below, on February 10, 2026, upon the recommendation of the compensation committee, our board of directors adopted, subject to stockholder approval, the 2020 Plan Amendment. If this proposal is approved by our stockholders, we intend to register the additional shares reserved for issuance under the Amended Plan by filing a Registration Statement on Form S-8 as soon as practicable following such approval.
The Current Plan is our existing equity incentive plan, which was originally approved by the board of directors on February 13, 2020, and by our stockholders on May 29, 2020. When the Current Plan was adopted, we expected that the share pool under the Current Plan would allow us to continue to grant equity awards at our historic rates for approximately ten years. However, the remaining share pool under the Current Plan is insufficient to meet our equity compensation needs. The Amended Plan increases the share pool under the Current Plan by 3,200,000 shares of Class A common stock. No other changes are being made to the Current Plan. If approved, the new shares reserved under the Amended Plan would represent approximately 15.08% of our 34,939,417 outstanding shares of Class A Common Stock and 18,000,000 shares of Class B Common Stock as of March 31, 2026, on a fully diluted basis. Our board of directors believes the proposed dilution to stockholders as a result of the amendment is judicious and sustainable and, importantly, critical to meeting our business goals.
We intend to utilize the Amended Plan as we have utilized the Current Plan: specifically, to grant equity awards to our employees, non-employee directors, consultants, and advisors in order to recruit, incentivize, retain and reward those who are critical to our success. Our compensation committee determined the requested number of shares for the Amended Plan based on projected new-hire equity awards, projected annual equity awards to our employees and non-employee directors, employee recognition and promotion awards, and an assessment of the magnitude of the share reserve under the Amended Plan that our stockholders would likely find acceptable. If stockholders approve the 2020 Plan Amendment, subject to adjustment in the event of stock splits and other similar events, awards may be made under the Amended Plan for up to a number of shares of Class A common stock equal to the sum of: (i) 3,200,000 shares of Class A common stock; and (ii) such additional number of shares of Class A common stock (up to 170,412 shares) as is equal to the sum of (x) the number of shares of Class A common stock reserved for issuance under the Current Plan that remain available for grant under the Current Plan immediately prior to the date that the 2020 Plan Amendment is approved by our stockholders and (y) the number of shares of Class A common stock subject to awards granted under the Current Plan that are outstanding as of the date that the 2020 Plan Amendment is approved by our stockholders and which awards expire, terminate or are otherwise surrendered, cancelled, forfeited or repurchased by us at their original issuance price pursuant to a contractual repurchase right (subject, however, in the case of incentive stock options, to any limitations under the Internal Revenue Code of 1986, as amended, and any regulations thereunder, which we refer to as the Code). The Amended Plan does not include an evergreen provision and includes several features that are consistent with protecting the interests of our stockholders and sound corporate governance practices, as described below.
The following table includes information, as of March 31, 2026, regarding all of our outstanding equity awards under all of our equity-based compensation plans and arrangements under which shares of Class A common stock may be issued. This includes shares subject to outstanding awards under the Current Plan and our 2010 Equity Incentive Plan, and up to 123,806 shares available under the Current Plan for future awards that we may make between March 31, 2026 and the date of the Annual Meeting, but does not include shares issuable under our 2017 Employee Stock Purchase Plan, as amended.

Weighted average remaining contractual term of outstanding stock options (years)

Number of shares of Class A common stock outstanding 34,939,417
(1) Includes 1,281,000 shares of Class A Common Stock underlying the 2025 Performance-Based Vesting Options (assuming maximum performance for all outstanding performance-based vesting options).
(2) This number includes 90,000 options to be issued in connection with recent officer promotions.
As of March 31, 2026, there were no outstanding shares of restricted stock, no stock appreciation rights, which we refer to as SARs, or any other stock-based awards.
We expect that the proposed share pool under the Amended Plan will allow us to continue to grant equity awards at our historic rates for approximately three years, but the actual duration of the share pool may vary based on changes in participation and our stock price.
We believe that our stock-based compensation programs have been integral to our success in the past and will be important to our ability to succeed in the future. If the 2020 Plan Amendment is not approved by our stockholders, we will not be able to make equity incentive awards to meet our hiring and retention needs in a highly competitive market, which could have an adverse impact on our business. Further, if the 2020 Plan Amendment is not approved, we could be forced to increase cash compensation, which will reduce the amount of resources we are able to allocate to meet our business needs and objectives. Therefore, the approval of the 2020 Plan Amendment is vital to our future success.
Following below is a discussion of:
Highlights of the Amended Plan;
Reasons Why Stockholders Should Approve the 2020 Plan Amendment;
Information Regarding Burn Rate and Overhang; and
Description of the Amended Plan.
Highlights of the Amended Plan
No liberal share recycling. Shares of Class A common stock that are delivered to us or held back upon the exercise or settlement of an award to cover the exercise price or tax withholding under the Amended Plan are not added back to the shares of Class A common stock available for issuance under the Amended Plan. In addition, shares of Class A common stock repurchased by us on the open market using the proceeds from the exercise of an award made under the Amended Plan will not increase the number of shares available for future grant of awards under the Amended Plan.
No discounted stock options or SARs. Stock options and SARs must be granted with an exercise price that is at least equal to the fair market value of the Class A common stock on the date of grant.
No repricing of options or SARs. The Amended Plan prohibits the direct or indirect repricing of stock options or SARs without stockholder approval.
Independent committee administers awards to non-employee directors. Awards granted to non-employee directors must be granted and administered by a committee of the board of directors which are independent directors within the meaning of any stock exchange on which we list our Class A common stock.
Dividends and dividend equivalents on restricted stock and restricted stock units not paid until award vests. Any dividends or dividend equivalents paid with respect to restricted stock or restricted stock units, which we refer to as RSUs, will be subject to the same restrictions on transfer and forfeitability as the award with respect to which they are paid.
No evergreen. The Amended Plan does not include an "evergreen" or other provision that automatically increases the number of shares available for grant under the plan and therefore any increase to the maximum share reserve in the Amended Plan is subject to approval by our stockholders, allowing our stockholders to have a say in our equity compensation programs.
Clawback policy. In accepting an award under the Amended Plan, a participant agrees to be bound by any clawback policy that the we have in effect or may adopt in the future.
No automatic vesting of awards on a change in control event. The Amended Plan does not provide for the automatic vesting of awards in connection with a change in control event.
Material amendments require stockholder approval. Stockholder approval is required prior to an amendment of the Amended Plan that would (i) materially increase the number of shares authorized (other than as provided under the Amended Plan with respect to certain corporate events or substitute awards), (ii) expand the types of awards that may be granted, or (iii) materially expand the class of participants eligible to participate.
Reasons Why Stockholders Should Approve the 2020 Plan Amendment
Incentivizes, Retains and Motivates Talent. It is critical to our success that we incentivize, retain and motivate the best talent in what is a competitive labor market. Our equity-based compensation program has always been and will continue to be a key component in our ability to pay market-competitive compensation to our employees.
Aligns with Our Pay-for-Performance Compensation Philosophy. We believe that equity-based compensation is inherently performance-based. As the value of our stock appreciates, our employees receive greater compensation at the same time that our stockholders are receiving a greater return on their investment. Conversely, if the stock price does not appreciate following the grant of an equity award, then our employees would not receive any compensation in respect of stock options and would receive lower compensation than intended in respect of RSUs.
Aligns Employee and Director Interests with Stockholder Interests. Providing our employees and non-employee directors with compensation in the form of equity directly aligns the interests of those employees and non-employee directors with the interests of our stockholders. If the 2020 Plan Amendment is approved by our stockholders, we will be able to continue granting equity-based incentives that foster this alignment between our employees and non-employee directors and our stockholders.
Consistent with Stockholder Interests and Sound Corporate Governance. As described under the heading "Highlights of the Amended Plan" and more thoroughly below, the Amended Plan was purposefully designed to include features that are consistent with the interests of our stockholders and sound corporate governance practices.
Information Regarding Burn Rate and Overhang
In developing our share request for the Amended Plan and analyzing the impact of utilizing equity as a means of compensation on our stockholders, we considered both our "burn rate" and our "overhang."
Burn rate provides a measure of the potential dilutive impact of our annual equity award program. Gross burn rate is defined as the number of equity awards granted in the year divided by the basic weighted average number of common shares outstanding. Our gross burn rate is close to the benchmark set by Institutional Shareholder Services.
The table below sets forth our gross burn rate for the 2025, 2024 and 2023 fiscal years, as well as the average over those years.

Includes 1,281,000 shares of Class A Common Stock underlying the 2025 Performance-Based Vesting Options (assuming maximum performance for all outstanding performance-based vesting options).
Overhang is a measure of potential dilution and is defined as the sum of (i) the total number of shares underlying all equity awards outstanding and (ii) the total number of shares available for future awards, divided by the number of common shares outstanding. As of March 31, 2026, our overhang was 10.17%, reflecting:
5,670,232 outstanding options to purchase shares of our Class A common stock under both of our 2020 Plan and our 2010 Stock Incentive Plan;
201,818 outstanding RSUs
123,806 shares available for future award grants;
34,939,417 shares of Class A common stock outstanding; and
18,000,000 shares of Class B common stock outstanding.
If the 3,200,000 shares proposed to be authorized for grant under the Amended Plan are included in the calculation, our overhang on March 31, 2026 would have been 14.80%.

Description of the Amended Plan
The following is a brief summary of the Amended Plan. A copy of each of the Amended Plan and the 2020 Plan Amendment is attached as Appendix A and Appendix B, respectively, to this proxy statement. Please note that the following summary describes the Amended Plan as it is proposed to be amended by the 2020 Plan Amendment, as opposed to the Current Plan. As noted above, the 2020 Plan Amendment amends the Current Plan solely to increase the number of shares available for the issuance of awards. References to our board of directors in this summary shall include the compensation committee or any similar committee appointed by our board of directors to administer the Amended Plan.
Types of Awards; Shares Available for Awards; Share Counting Rules
The Amended Plan provides for the grant of incentive stock options intended to qualify under Section 422 of the Code, nonstatutory stock options, SARs, restricted stock, RSUs, and other stock-based awards as described below, which we collectively refer to as awards.
Subject to adjustment in the event of stock splits, stock dividends or similar events, awards may be made under the Amended Plan (any or all of which may be in the form of incentive stock options) for up to 8,200,000 shares of Class A common stock. Subject to adjustment in the event of stock splits, stock dividends or similar events, the maximum number of shares of our Class A common stock with respect to which awards may be granted to any participant under the Amended Plan is 2,000,000 per calendar year.
For purposes of counting the number of shares available for the grant of awards under the Amended Plan and the sublimit of the Amended Plan, all shares of Class A common stock covered by SARs will be counted against the number of shares available for the grant of awards and against the sublimit of the Amended Plan. However, SARs that may be settled only in cash will not be so counted. In addition, if we grant a SAR in tandem with an option for the same number of shares of our Class A common stock and provide that only one such award may be exercised, which we refer to as a tandem SAR, only the shares covered by the option, and not the shares covered by the tandem SAR, will be so counted, and the expiration of one in connection with the other's exercise will not restore shares to the Amended Plan.
Shares covered by awards under the Amended Plan that expire or are terminated, surrendered, or cancelled without having been fully exercised or are forfeited in whole or in part (including as the result of shares of Class A common stock subject to such award being repurchased by us at the original issuance price pursuant to a contractual repurchase right) or that result in any shares of Class A common stock not being issued (including as a result of a SAR that was settleable either in cash or in stock actually being settled in cash) will again be available for the grant of awards under the Amended Plan (subject, in the case of incentive stock options, to any limitations under the Code). In the case of the exercise of a SAR, the number of shares counted against the shares available for the grant of awards and against the sublimit of the Amended Plan will be the full number of shares subject to the SAR multiplied by the percentage of the SAR actually exercised, regardless of the number of shares actually used to settle the SAR upon exercise, and the shares covered by a tandem SAR will not again become available for grant upon the expiration or termination of the tandem SAR.
Shares of Class A common stock that are delivered (by actual delivery, attestation, or net exercise) to us by a participant to purchase shares of Class A common stock upon exercise of an award or to satisfy tax withholding obligations with respect to awards (including shares retained from the award creating the tax obligation) will not be added back to the number of shares available for the future grant of awards under the Amended Plan. Shares purchased by us on the open market using proceeds from the exercise of an award will not increase the number of shares available for future grant of awards.
In connection with a merger or consolidation of an entity with us or our acquisition of property or stock of an entity, our board of directors may grant awards under the Amended Plan in substitution for any options or other stock or stock-based awards granted by such entity or an affiliate thereof on such terms as our board of directors determines appropriate in the circumstances, notwithstanding any limitation on awards contained in the Amended Plan. Any such substitute awards shall not count against the overall share limits or any sublimits of the Amended Plan, except as required by reason of Section 422 and related provisions of the Code.
Description of Awards
Stock Options. Optionees receive the right to purchase a specified number of shares of Class A common stock at a specified exercise price and subject to the other terms and conditions that are specified in connection with the option grant. An option that is not intended to be an "incentive stock option" is a "nonstatutory stock option." Options may not be granted at an exercise price that is less than 100% of the fair market value of our Class A common stock on the date of grant. If our board of directors approves the grant of an option with an exercise price to be determined on a future date, the exercise price may not be less than 100% of the fair market value of our Class A common stock on that future date. Under present law, incentive stock options may not be granted at an exercise price less than 110% of the fair market value in the case of stock options granted to optionees holding more than 10% of the total combined voting power of all classes of our stock or any of our subsidiaries. Under the terms of the Amended Plan, options may not be granted for a term in excess of ten years (and, under present law, five years in the case of incentive stock options granted to optionees holding greater than 10% of the total combined voting power of all classes of our stock or any of our subsidiaries).
Options may be exercised by delivery to us of a notice of exercise in a form (which may be electronic) approved by us. Upon exercise of options, the option exercise price must be paid in full either (i) in cash or check, payable to the order of our company; (ii) except as may otherwise be provided in the applicable option agreement or approved by the board of directors, by delivery of an undertaking by, or instructions by the optionee to, a creditworthy broker to deliver funds sufficient to pay the exercise price and any withholding; (iii) to the extent provided for in the applicable option agreement or approved by the board of directors and subject to certain conditions, by delivery shares of Class A common stock held by the participant having a fair market price equal to the exercise price; (iv) to the extent provided for in the applicable nonstatuatory stock option agreement or approved by the board of directors, by net exercise; (v) to the extent permitted by applicable law and provided for in the applicable option agreement or approved by the board of directors, in its sole discretion, by delivery of a promissory note (other than a participant who is an officer or director of ours) or payment of other lawful consideration; or (vi) by any combination of the foregoing.
Stock Appreciation Rights. A SAR is an award entitling the holder, upon exercise, to receive a number of shares of our Class A common stock, or cash (or a combination of shares of our Class A common stock and cash) determined by reference to appreciation, from and after the date of grant, in the fair market value of a share of our Class A common stock over the measurement price. The Amended Plan provides that the measurement price of a SAR may not be less than the fair market value of our Class A common stock on the date the SAR is granted (provided, however, that if our board of directors approves the grant of a SAR effective as of a future date, the measurement price shall not be less than 100% of the fair market value on such future date) and that SARs may not be granted with a term in excess of 10 years.
Limitation on Repricing of Options or SARs. With respect to options and SARs, unless such action is approved by stockholders or otherwise permitted under the terms of the Amended Plan in connection with certain changes in capitalization and reorganization events, we may not (1) amend any outstanding option or SAR granted under the Amended Plan to provide an exercise price or measurement price per share that is lower than the then-current exercise price or measurement price per share of such outstanding option or SAR, (2) cancel any outstanding option or SAR (whether or not granted under the Amended Plan) and grant in substitution therefor new awards under the Amended Plan (other than certain substitute awards issued in connection with an acquisition by us, described above) covering the same or a different number of shares of our Class A common stock and having an exercise price or measurement price per share lower than the then-current exercise price or measurement price per share of the canceled option or SAR, (3) cancel in exchange for a cash payment any outstanding option or SAR with an exercise price or measurement price per share above the then-current fair market value of our Class A common stock, or (4) take any other action under the Amended Plan that constitutes a "repricing" within the meaning of the rules of the New York Stock Exchange, or NYSE.
Restricted Stock Awards. Restricted stock awards entitle recipients to acquire shares of our Class A common stock, subject to our right to repurchase all or part of such shares at their issue price or other stated or formula price (or to require forfeiture of such shares if issued at no cost) in the event that the conditions specified in the applicable award are not satisfied prior to the end of the applicable restriction period established for such award. Any dividends (whether paid in cash, stock or property) declared and paid by us with respect to shares of restricted stock will be paid to the participant only if and when such shares become free from the restrictions on transferability and forfeitability that apply to such shares. No interest will be paid on any such unvested dividends.
Restricted Stock Units. RSUs entitle the recipient to receive shares of our Class A common stock, or cash equal to the fair market value of such shares, to be delivered at the time such award vests pursuant to the terms and conditions established by our board of directors. Our board of directors may provide that settlement of RSUs will be deferred, on a mandatory basis or at the election of the participant in a manner that complies with Section 409A of the Code. A participant has no voting rights with respect to any RSU. Our board of directors may provide that a grant of RSUs may provide the participant with the right to receive an amount equal to any dividends or other distributions declared and paid on an equal number of outstanding shares of our Class A common stock. Any such dividend equivalents may be settled in cash and/or shares of our Class A common stock and will be subject to the same restrictions on transfer and forfeitability as the RSUs with respect to which such dividend equivalents are awarded. No interest will be paid on any such dividend equivalents.
Other Stock-Based Awards. Under the Amended Plan, our board of directors may grant other awards of shares of Class A common stock and other awards that are valued in whole or in part by reference to, or are otherwise based on, shares of Class A common stock or other property, having such terms and conditions as our board of directors may determine. We refer to these types of awards as other stock-based awards. Other stock-based awards may be used as a form of payment in the settlement of other awards granted under the Amended Plan or as payment in lieu of compensation to which a participant is otherwise entitled. Other stock-based awards may be paid in shares of Class A common stock or cash, as the board of directors may determine.
Performance Awards. Awards made under the Amended Plan may be made subject to the achievement of performance goals. We refer to such awards as performance awards. The board of directors may specify that the granting, vesting and/or payout of a performance award will be subject to the achievement of one or more objective performance measures established by the board of directors, which may be based on the relative or absolute attainment of specified levels of one or any combination of the following, which may be determined pursuant to generally accepted accounting principles, or GAAP, or on a non-GAAP basis, as determined by the board of directors: (i) net income, (ii) earnings before or after discontinued operations, interest, taxes, depreciation and/or amortization, (iii) operating profit before or after discontinued operations and/or taxes, (iv) sales, (v) sales growth, (vi) earnings growth, (vii) cash flow or cash position, (viii) gross margins, (ix) stock price, (x) market share, (xi) return on sales, assets, equity or investment, (xii) improvement of financial ratings, (xiii) achievement of balance sheet or income statement objectives, (xiv) total stockholder return or (xv) any other performance measure established by the board of directors. Such goals may reflect absolute entity or business unit performance or a relative comparison to the performance of a peer group of entities or other external measure of the selected performance criteria and may be absolute in their terms or measured against or in relationship to other companies comparably, similarly or otherwise situated. The board of directors may specify that such performance measures can be adjusted to exclude any one or more of (i) non-recurring or unusual gains or losses, (ii) gains or losses on the dispositions of discontinued operations, (iii) the cumulative effects of changes in accounting principles, (iv) the write-down of any
asset, (v) fluctuation in foreign currency exchange rates, (vi) charges for restructuring and rationalization programs, and
(vii) any other factors the board of directors may determine. Such performance measures may vary by participant and may be different for different awards; may be particular to a participant or the department, branch, line of business, subsidiary or other unit in which the participant works and may cover such period as may be specified by the board of directors. The board of directors may adjust the cash or number of shares payable pursuant to a performance award, and the board of directors may, at any time, waive the achievement of the applicable performance measures, including in the case of the death or disability of the participant or a change in control of our company.
Eligibility to Receive Awards
All of our employees, officers, directors, consultants and advisors are eligible to receive awards under the Amended Plan; however, incentive stock options may only be granted to our employees.
As of March 31, 2026 approximately 1,645 persons were eligible to receive awards under the Current Plan, including 1,599 employees (excluding officers), seven executive officers (all of whom are also employees), six directors (excluding executive officers) and 33 consultants. As of March 31, 2026, we had no advisors (excluding consultants).
On March 31, 2026, the last reported sale price of our Class A common stock on the NYSE was $25.50.
Transferability of Awards
Awards may not be sold, assigned, transferred, pledged or otherwise encumbered by a participant, either voluntarily or by operation of law, except by will or the laws of descent and distribution or, other than in the case of an incentive stock option, pursuant to a qualified domestic relations order. During the life of the participant, awards are exercisable only by the participant. However, except with respect to awards that are subject to Section 409A of the Code, our board of directors may permit or provide in an award for the gratuitous transfer of the award by the participant to or for the benefit of any immediate family member, family trust or other entity established for the benefit of the participant and/or an immediate family member thereof if we would be eligible to use a Form S-8 under the Securities Act of 1933, as amended, for the registration of the sale of the common stock subject to such award to the proposed transferee. Further, we are not required to recognize any transfer until such time as the permitted transferee has, as a condition to the transfer, delivered to us a written instrument in form and substance satisfactory to us confirming that such transferee will be bound by all of the terms and conditions of the award. None of the restrictions described in this paragraph prohibit a transfer from the participant to us.
No Rights as a Stockholder
No participant shall have any rights as a stockholder with respect to any shares of Class A common stock to be issued with respect to an award granted under the Amended Plan until becoming a record holder of such shares, subject to the terms of an award agreement.
Clawback
In accepting an award under the Amended Plan, a participant agrees to be bound by any clawback policy that we have in effect or may adopt in the future, including our Clawback Policy.

New Plan Benefits Table
The granting of awards under the Amended Plan is discretionary, and we cannot now determine the number or type of awards to be granted in the future to any particular person or group, other than as set forth below. Pursuant to our non-employee director compensation policy (as such was revised for fiscal year 2026), we are are obligated to grant each of our non-employee directors a stock grant in the form of RSUs of that number of whole shares of our Class A common stock determined by dividing $150,000 by the average fair market value of our Class A common stock over a period of 30 trading days prior to the date of grant, upon initial election to our board of directors, which is pro-rated as of the date of such election, and as of the first meeting our of our board of directors following each annual meeting of stockholders thereafter, including the Annual Meeting, under the terms of our Non-Employee Director Compensation Policy.

Represents the aggregate dollar value of annual stock grants in the form of RSUs to be granted in 2026 to each non-employee director. Under our non-employee director compensation policy (as such was updated for fiscal year 2026), as of the first meeting of our board of directors following the Annual Meeting, each non-employee director will receive a stock grant in the form of RSUs of that number of whole shares of our Class A common stock determined by dividing $150,000 by the average fair market value of our Class A common stock over a period of 30 trading days prior to the date of grant. The amount set forth in the Dollar Value column above equals $150,000 multiplied by five non-employee directors who are expected to continue serving as such following the Annual Meeting (including the two non-employee directors who are standing for election at the Annual Meeting, which election is more fully described in Proposal 1 of this proxy statement). Excludes (i) RSUs that the non-employee directors will be entitled to receive under our Non-Employee Director Compensation Policy for subsequent years following 2026 and (ii) any discretionary awards that any
non-employee director may be awarded under the Amended Plan.
The numberof shares underlying the RSU awards to be made to the non-employee directors on the date of the Annual Meetning (as more fully described in footnote (1) above) is not determinabler at this time as such awardds wil be determined based on the stock price of of the Class A Common Stock over a period of 30 trading days prior to the grant.
Administration
The Amended Plan will be administered by our board of directors. Our board of directors has the authority to grant awards and to adopt, amend and repeal the administrative rules, guidelines and practices relating to the Amended Plan that it deems advisable and to construe and interpret the provisions of the Amended Plan and any award agreements entered into under the Amended Plan. Our board of directors may correct any defect, supply any omission or reconcile any inconsistency in the Amended Plan or any award. All actions and decisions by our board of directors with respect to the Amended Plan and any awards made under the Amended Plan will be made in our board of directors' discretion and will be final and binding on all persons having or claiming any interest in the Amended Plan or in any award.
Pursuant to the terms of the Amended Plan, our board of directors may delegate any or all of its powers under the Amended Plan to one or more committees or subcommittees of our board of directors. The board of directors has authorized the compensation committee to administer certain aspects of the Amended Plan, including the granting of awards to executive officers. Awards granted to non-employee directors must be granted and administered by a committee of the board of
directors, all of the members of which are independent directors within the meaning of any stock exchange on which we list our Class A common stock.
Subject to any applicable limitations contained in the Amended Plan, the board of directors, the compensation committee, or any other committee to whom the board of directors delegates authority, as the case may be, selects the recipients of awards and determines (i) the number of shares of common stock, cash or other consideration covered by awards and the terms and conditions of such awards, including the dates upon which such awards become exercisable or otherwise vest,
(ii) the exercise or measurement price of awards, if any, and (iii) the duration of awards.
Each award under the Amended Plan may be made alone or in addition or in relation to any other award. The terms of each award need not be identical, and our board of directors need not treat participants uniformly. Our board of directors will determine the effect on an award of the disability, death, termination or other cessation of employment, authorized leave of absence or other change in the employment or other status of a participant, and the extent to which, and the period during which, the participant (or the participant's legal representative, conservator, guardian or designated beneficiary) may exercise rights or receive any benefits under an award. The board of directors may at any time provide that any award shall become immediately exercisable in whole or in part, free from some or all restrictions or conditions or otherwise realizable in whole or in part, as the case may be.
In the event of any stock split, reverse stock split, stock dividend, recapitalization, combination of shares, reclassification of shares, spin-off or other similar change in capitalization or event, or any dividend or distribution to holders of our Class A common stock, other than an ordinary cash dividend, we are required to make equitable adjustments (or make substituted awards, as applicable), in the manner determined by our board of directors, to (i) the number and class of securities available under the Amended Plan, (ii) the share counting rules set forth in the Amended Plan, (iii) the sublimit contained in the Amended Plan, (iv) the number and class of securities and exercise price per share of each outstanding option, (v) the share- and per-share provisions and the measurement price of each outstanding SAR, (vi) the number of shares subject to and the repurchase price per share subject to each outstanding award of restricted stock, and (vi) the share and per-share-related provisions and the purchase price, if any, of each outstanding RSU award and each outstanding other stock-based award.
We will indemnify and hold harmless each director, officer, employee or agent to whom any duty or power relating to the administration or interpretation of the Amended Plan has been or will be delegated against any cost or expense (including attorneys' fees) or liability (including any sum paid in settlement of a claim with our board of directors' approval) arising out of any act or omission to act concerning the Amended Plan unless arising out of such person's own fraud or bad faith. Except as otherwise provided under the Amended Plan with respect to repricing outstanding stock options or SARs or with respect to amendments to the Amended Plan that require stockholder approval, our board of directors may amend, modify or terminate any outstanding award, including but not limited to, substituting for an award another award of the same or a different type, changing the date of exercise or realization, and converting an incentive stock option to a nonstatutory stock option, provided that the participant's consent to any such action will be required unless our board of directors determines that the action, taking into account any related action, does not materially and adversely affect the participant's rights under the Amended Plan or the change is otherwise permitted under the terms of the Amended Plan in connection with a change in capitalization or reorganization event.
Reorganization Events.
The Amended Plan contains provisions addressing the consequences of any reorganization event. A reorganization event is defined under the Amended Plan as (a) any merger or consolidation of us with or into another entity as a result of which all of our Class A common stock is converted into or exchanged for the right to receive cash, securities or other property, or is canceled, (b) any transfer or disposition of all of our Class A common stock for cash, securities or other property pursuant to a share exchange or other transaction or (c) our liquidation or dissolution.
Provisions Applicable to Awards Other than Restricted Stock. Under the Amended Plan, if a reorganization event occurs, our board of directors may take any one or more of the following actions as to all or any (or any portion of) outstanding awards other than restricted stock on such terms as our board of directors determines (except to the extent specifically provided otherwise in an applicable award agreement or another agreement between a participant and us): (1) provide that such awards shall be assumed, or substantially equivalent awards shall be substituted, by the acquiring or succeeding corporation (or an affiliate thereof), (2) upon written notice to a participant, provide that all of the participant's unvested awards will be forfeited immediately before the reorganization event and/or that all of the participant's unexercised awards will terminate immediately prior to the consummation of such reorganization event unless exercised by the participant (to
the extent then exercisable) within a specified period following the date of such notice, (3) provide that outstanding awards shall become exercisable, realizable, or deliverable, or restrictions applicable to an award shall lapse, in whole or in part prior to or upon such reorganization event, (4) in the event of a reorganization event under the terms of which holders of our common stock will receive upon consummation thereof a cash payment for each share surrendered in the reorganization event, which we refer to as the Acquisition Price, make or provide for a cash payment to participants with respect to each award held by a participant equal to (A) the number of shares of our common stock subject to the vested portion of the award (after giving effect to any acceleration of vesting that occurs upon or immediately prior to such reorganization event) multiplied by (B) the excess, if any, of (I) the Acquisition Price over (II) the exercise, measurement or purchase price of such award and any applicable tax withholdings, in exchange for the termination of such award, (5) provide that, in connection with our liquidation or dissolution, awards shall convert into the right to receive liquidation proceeds (if applicable, net of the exercise, measurement or purchase price thereof and any applicable tax withholdings) and (6) any combination of the foregoing. Our board of directors is not obligated to treat all awards, all awards held by a participant, or all awards of the same type, identically. Certain RSU awards that are subject to Section 409A of the Code will be settled in accordance with the terms of the applicable award agreement.
Provisions Applicable to Restricted Stock. Upon the occurrence of a reorganization event other than our liquidation or dissolution, our repurchase and other rights with respect to outstanding restricted stock will inure to the benefit of our successor and will, unless our board of directors determines otherwise, apply to the cash, securities or other property which our common stock was converted into or exchanged for pursuant to such reorganization event in the same manner and to the same extent as they applied to such restricted stock. However, our board of directors may either provide for termination or deemed satisfaction of such repurchase or other rights under the instrument evidencing any restricted stock or any other agreement between a participant and us, either initially or by amendment or provide for forfeiture of such restricted stock if issued at no cost. Upon the occurrence of a reorganization event involving our liquidation or dissolution, except to the extent specifically provided to the contrary in the instrument evidencing any award of restricted stock or any other agreement between the participant and us, all restrictions and conditions on all restricted stock then outstanding shall automatically be deemed terminated or satisfied.
Provisions for Foreign Participants
The board of directors may establish one or more sub-plans under the Amended Plan to satisfy applicable securities, tax or other laws of various jurisdictions. The board of directors will establish such sub-plans by adopting supplements to the Amended Plan containing any limitations on the board of director's discretion under the Amended Plan and any additional terms and conditions not otherwise inconsistent with the Amended Plan as the board of directors deems necessary or desirable. All supplements adopted by the board of directors will be deemed to be part of the Amended Plan, but each supplement will only apply to participants within the affected jurisdiction.
Amendment or Termination
If we receive stockholder approval of the Amended Plan, no award may be granted under the Amended Plan after May 28, 2030, but awards previously granted may extend beyond that date. Our board of directors may amend, suspend or terminate the Amended Plan or any portion of the Amended Plan at any time, except that no amendment that would require stockholder approval under the rules of the NYSE may be made effective unless and until such amendment has been approved by our stockholders. If at any time the approval of our stockholders is required as to any other modification or amendment under Section 422 of the Code or any successor provision with respect to incentive stock options, our board of directors may not effect such modification or amendment without such approval. Unless otherwise specified in the amendment, any amendment to the Amended Plan adopted in accordance with the procedures described above will apply to, and be binding on the holders of, all awards outstanding under the Amended Plan at the time the amendment is adopted, provided that our board of directors determines that such amendment, taking into account any related action, does not materially and adversely affect the rights of participants under the Amended Plan. No award will be made that is conditioned on stockholder approval of any amendment to the Amended Plan unless the award provides that (i) it will terminate or be forfeited if stockholder approval of such amendment is not obtained within no more than 12 months from the date the award was granted and (ii) it may not be exercised or settled (or otherwise result in the issuance of shares of our Class A common stock) prior to the receipt of such stockholder approval.
Federal Income Tax Consequences
The following is a summary of the United States federal income tax consequences that generally will arise with respect to awards granted under the Amended Plan. This summary is based on the federal tax laws in effect as of the date of this proxy statement. In addition, this summary assumes that all awards are exempt from, or comply with, the rules under
Section 409A of the Code regarding nonqualified deferred compensation. Changes to these laws could alter the tax consequences described below.
Incentive Stock Options. A participant will not have income upon the grant of an incentive stock option. Also, except as described below, a participant will not have income upon exercise of an incentive stock option if the participant has been employed by our company or its corporate parent or 50% or majority-owned corporate subsidiary at all times beginning with the option grant date and ending three months before the date the participant exercises the option. If the participant has not been so employed during that time, then the participant will be taxed as described below under "Nonstatutory Stock Options." The exercise of an incentive stock option may subject the participant to the alternative minimum tax.
A participant will have income upon the sale of the stock acquired under an incentive stock option at a profit (if sales proceeds exceed the exercise price). The type of income will depend on when the participant sells the stock. If a participant sells the stock more than two years after the option was granted and more than one year after the option was exercised, then all of the profit will be long-term capital gain. If a participant sells the stock prior to satisfying these waiting periods, then the participant will have engaged in a disqualifying disposition and a portion of the profit will be ordinary income and a portion may be capital gain. This capital gain will be long-term if the participant has held the stock for more than one year and otherwise will be short-term. If a participant sells the stock at a loss (sales proceeds are less than the exercise price), then the loss will be a capital loss. This capital loss will be long-term if the participant held the stock for more than one year and otherwise will be short-term.
Nonstatutory Stock Options. A participant will not have income upon the grant of a nonstatutory stock option. A participant will have compensation income upon the exercise of a nonstatutory stock option equal to the value of the stock on the day the participant exercised the option less the exercise price. Upon sale of the stock, the participant will have capital gain or loss equal to the difference between the sales proceeds and the value of the stock on the day the option was exercised. This capital gain or loss will be long-term if the participant has held the stock for more than one year and otherwise will be short-term.
Stock Appreciation Rights. A participant will not have income upon the grant of a SAR. A participant generally will recognize compensation income upon the exercise of a SAR equal to the amount of the cash and the fair market value of any stock received. Upon the sale of the stock, the participant will have capital gain or loss equal to the difference between the sales proceeds and the value of the stock on the day the SAR was exercised. This capital gain or loss will be long-term if the participant held the stock for more than one year and otherwise will be short-term.
Restricted Stock Awards. A participant will not have income upon the grant of restricted stock unless an election under Section 83(b) of the Code is made within 30 days of the date of grant. If a timely 83(b) election is made, then a participant will have compensation income equal to the value of the stock less the purchase price. When the stock is sold, the participant will have capital gain or loss equal to the difference between the sales proceeds and the value of the stock on the date of grant. If the participant does not make an 83(b) election, then when the stock vests the participant will have compensation income equal to the value of the stock on the vesting date less the purchase price. When the stock is sold, the participant will have capital gain or loss equal to the sales proceeds less the value of the stock on the vesting date. Any capital gain or loss will be long-term if the participant held the stock for more than one year and otherwise will be short-term.
Restricted Stock Units. A participant will not have income upon the grant of an RSU. A participant is not permitted to make a Section 83(b) election with respect to a RSU award. When the RSU vests, the participant will have income on the vesting date in an amount equal to the fair market value of the stock on the vesting date less the purchase price, if any.
When the stock is sold, the participant will have capital gain or loss equal to the sales proceeds less the value of the stock on the vesting date. Any capital gain or loss will be long-term if the participant held the stock for more than one year and otherwise will be short-term.
Other Stock-Based Awards. The tax consequences associated with any other stock-based award granted under the Amended Plan will vary depending on the specific terms of such award. Among the relevant factors are whether or not the award has a readily ascertainable fair market value, whether or not the award is subject to forfeiture provisions or
restrictions on transfer, the nature of the property to be received by the participant under the award, and the participant's holding period and tax basis for the award or underlying common stock.
Tax Consequences to Us. There will be no tax consequences to us except that we will be entitled to a deduction when a participant has compensation income, subject to the limitations of Section 162(m) of the Code.
PROPOSAL 4 -NON-BINDING ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION
As required pursuant to Section 14A of the Securities Exchange Act of 1934, our board is asking that stockholders cast a non-binding, advisory vote FOR the following resolution:
"RESOLVED, that the compensation of the company's named executive officers as disclosed in the Compensation Discussion and Analysis, the accompanying compensation tables, and the related narrative disclosure in this Proxy Statement, is hereby approved."
This proposal, commonly known as a "say-on-pay" proposal, gives you as a stockholder the opportunity to express your views on our named executive officers' compensation. This vote is not intended to address any specific element of our compensation programs, but rather the overall compensation of our named executive officers and the philosophies, policies and practices described in this Proxy Statement.
As described in the "Compensation Discussion and Analysis" section of this Proxy Statement, or CD&A, our primary objective with respect to executive compensation is to attract, retain and motivate highly talented individuals who have the skills and experience necessary to successfully execute our business strategy. Our executive compensation program is designed to (1) reward the achievement of our annual and long-term operating and strategic goals; (2) recognize individual contributions; (3) align the interests of our executives with those of our stockholders by rewarding performance that meets or exceeds established goals, with the ultimate objective of increasing stockholder value; and (4) retain and build our executive management team.
Stockholders are urged to read our CD&A, which describes in more detail how our executive compensation policies and procedures operate and are designed to achieve our compensation objectives, as well as the Summary Compensation Table and related compensation tables and narrative, which provide detailed information on the compensation of our named executive officers.
The vote solicited by this proposal is advisory and its outcome will not be binding on our board of directors nor require our board of directors to take any action. Moreover, the outcome of the vote will not be construed as overruling any decision of our board of directors or creating or implying any additional fiduciary duty of our board of directors (or any committee thereof). However, our board of directors and our compensation committee expects to take into account the outcome of this vote when considering future compensation arrangements for our named executive officers.

In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares subject to options, restricted stock units, warrants or other rights held by such person that are currently exercisable, will become exercisable or will vest and settle within 60 days of March 31, 2026 are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person.
Except as otherwise indicated in the footnotes to the table below, all persons listed below have sole voting and investment power with respect to the shares beneficially owned by them, subject to applicable community property laws. The information presented in the table below is not necessarily indicative of beneficial ownership for any other purpose.
Beneficial ownership representing less than one percent is denoted with an asterisk (*).
Percentage total voting power represents voting power of beneficially owned shares with respect to all shares of our Class A and Class B common stock, together as a single class. Each holder of Class A common stock is entitled to one vote per share of Class A common stock and each holder of Class B common stock is entitled to five votes per share of Class B common stock. Voting power of less than one percent is denoted with an asterisk (*).

Our Board of Directors
CORPORATE GOVERNANCE
Board of Directors
In accordance with the terms of our restated certificate of incorporation and by-laws, our board of directors is divided into three classes, each of which consists, as nearly as possible, of one-third of the total number of directors constituting our entire board of directors and each of whose members serve for staggered three-year terms. As a result, only one class of our board of directors will be elected each year. The members of the classes are as follows:
the class I directors are Claire Hughes Johnson, Charles R. Patton and Frank V. Wisneski, and their term expires at this Annual Meeting;
the class II directors are David J. Corrsin, George P. Sakellaris and Joseph W. Sutton, and their term expires at the annual meeting to be held in 2027; and
the class III directors are Jennifer L. Miller and Nickolas Stavropoulos, and their term expires at tm expires at the annual meeting to be held in 2028.
Each director in a class will be eligible to be chosen as a nominee for a new three-year term at the annual meeting of stockholders in the year in which their term expires. Charles R. Patton., will not be standing for re-election as a Class I director at the Annual Meeting. Our board of directors currently consists of eight members, and following the Annual Meeting subject to approval of this proposal, our board of directors will consist of seven members.
Below is information about each nominee for election as a class I director, as well as other members of our board of directors whose terms continue after the Annual Meeting. This information includes each director's age as of March 31, 2026 and length of service as a director of Ameresco, their principal occupation and business experience for at least the past five years and the names of other publicly held companies or investment companies of which he or she has served as a director for at least the past five years.
We believe that the backgrounds and qualifications of the directors, considered as a group, should provide a composite mix of experience, knowledge and abilities that will allow our board of directors to fulfill its responsibilities.
In addition to the information presented below regarding each director's specific experience, qualifications, attributes and skills that led our board of directors to the conclusion that he or she should serve as a director, we also believe that all of our directors have a reputation for integrity, honesty and adherence to high ethical standards. They each have demonstrated business acumen and an ability to exercise sound judgment, as well as a commitment of service to us.
There are no family relationships among any of our directors, nominees for director and executive officers.
Directors Whose Terms Expire at this Annual Meeting (Class I Directors)
Claire Hughes Johnson, age 53, has served as a director since July 2021. Since October 2014, Ms. Hughes Johnson has served in various roles with the global financial technology company Stripe, Inc., first as chief operating officer until April 2021 and since then as corporate officer and advisor. Prior to joining Stripe, she spent ten years at Google, leading various business teams including the launch and operations of Gmail and Google Apps. She was also the vice president responsible for Adwords mid-market revenue globally, Google Offers and the business operations of Google's self-driving car project. Ms. Hughes Johnson also currently serves on the board of two other public companies: a self-driving technology company, Aurora Innovation, Inc. and HubSpot, Inc. a customer relationship management platform, and on the board of various private and non-profit organization such as The Atlantic, Milton Academy and Brown University. She has previously served on the board of Hallmark Cards, Inc. We believe Ms. Johnson's experience directing product innovation as well as go to market- and operational strategy for a range of technology industry leaders contributes a valuable viewpoint to our board.
Frank V. Wisneski, age 79, has served as a director since 2011. Prior to retiring in 2001, Mr. Wisneski was a Partner and Senior Vice President at Wellington Management Company, LLP, an institutional asset manager serving clients globally, where he had worked since 1969. We believe that Mr. Wisneski is qualified to serve as a director because of his prior experience conducting financial and strategic analysis of companies, including emerging areas and companies, and establishing and building new investment products for institutional asset management clients. Since retiring, Mr. Wisneski has maintained a focus on financial and strategic analysis by serving on investment, finance and executive committees at
several nonprofit organizations. We believe his experience analyzing companies to support investment decisions contributes a valuable viewpoint to our board.
Directors Whose Terms Expire in 2027 (Class II Directors)
David J. Corrsin, age 67, has served as our executive vice president, general counsel and secretary, as well as a director, since 2000. From 1996 to 2000, Mr. Corrsin was executive vice president of Public Power International, Inc., an independent developer of power projects in Europe and southern Asia. We believe that Mr. Corrsin is qualified to serve as a director because of his extensive experience with energy regulations, federal, state and local regulatory authorities and complex energy construction and financing projects, gained through more than 30 years of energy-related legal practice, and his more than 30 years of service as an executive officer of our company.
George P. Sakellaris, age 79, who is our principal stockholder, has served as chairman of our board of directors and our president and chief executive officer since founding Ameresco in 2000. Mr. Sakellaris previously founded Noresco in 1989 and served as its president and chief executive officer until 2000. Mr. Sakellaris was a founding member and previously served as the president, and is currently a director, of the National Association of Energy Service Companies, a national trade organization representing the energy efficiency industry. We believe that Mr. Sakellaris is qualified to serve as a director because of his more than 35 years of experience in the energy services and renewable energy industries, his leadership experience, skill and familiarity with our business gained from serving as our chief executive officer for over 20 years, as well as his experience developed through founding and serving as chief executive officer of two previous energy services companies.
Joseph W. Sutton, age 78, has served as a director since 2002. Since 2000, Mr. Sutton has been the manager of Sutton Ventures Group, LLC, an energy investment firm that he founded. In 2007, he founded and has since led Consolidated Asset Management Services, or CAMS, which provides asset management, operations and maintenance, information technology, budgeting, contract management and development services to power plant ventures, oil and gas companies, renewable energy companies and other energy businesses. From 1992 to November 2000, Mr. Sutton worked for Enron Corporation, an energy company, where he most recently served as vice chairman and as chief executive officer of Enron International. We believe that Mr. Sutton is qualified to serve as a director because of his prior experience in the energy industry. For example, at both Sutton Ventures and CAMS, he has had significant experience in energy industry capital raising transactions, as well as in the ownership and management of, and the provision of advisory and other services to, a wide range of energy-related businesses. At Enron, Mr. Sutton was responsible for budgeting, financial reporting and planning for Enron's international business unit and oversaw the development, construction, financing, operation and management of numerous energy projects.
Directors Whose Terms Expire in 2028 (Class III Directors)
Jennifer L. Miller, age 70 has served as a director since 2015. From September 2015 through April 2020, Ms. Miller served as chief business sustainability officer of Sappi North America, the U.S. subsidiary of Sappi Limited, a producer of diversified cellulosic products including packaging and specialty papers, printing papers, biomaterials and biochemicals.
From 2002 to August 2015, Ms. Miller held senior management positions at Sappi North America, including executive vice president and chief sustainability officer, executive vice president - strategic marketing and executive vice president -publishing. We believe that Ms. Miller is qualified to serve as a director because of her qualifications and experience, including in the energy utility industry, where she previously served as general counsel for a gas utility, and more recently her sustainability leadership role at a multi-national manufacturing company. We believe her direct experience and understanding of how commercial/industrial enterprises evaluate and plan for energy efficiency initiatives are particularly valuable to the board and management as they continue to develop strategies for the commercial/industrial market.
Nickolas Stavropoulos, age 68, has served as a director since April 2019. Mr. Stavropoulos served as the president and chief operating officer of Pacific Gas and Electric Company from March 2017 through September 2018, as president, gas from August 2015 through February 2017 and executive vice president, gas operations from June 2011 to August 2015. In January 2019, Pacific Gas and Electric Company and its parent company, PG&E Corporation, filed voluntary petitions for reorganization under Chapter 11 of the U.S. Bankruptcy Code. Before joining Pacific Gas and Electric Company, Mr.
Stavropoulos served as executive vice president and chief operating officer of National Grid from 2007 through 2011. Prior to that role, Mr. Stavropoulos was president of KeySpan Energy Delivery, and also held several senior leadership roles at Colonial Gas Company and Boston Gas. Mr. Stavropoulos also serves as a director for the publicly traded company Enterprise Bancorp, and various private, and non-profit organizations, including TRC Companies, Picarro, Mosaic, Bentley University, and the Gas Technology Institute. We believe that Mr. Stavropoulos is qualified to serve as a director because
of his more than 40 years of experience in the energy industry, as well as detailed knowledge of the U.S. natural gas sector. He has extensive executive management, business, and leadership experience in areas such as safety, utility operations, information technology, regulatory affairs, strategic planning, supply chain, finance, sales, business development, and marketing.
Director Independence
A majority of our board of directors consists of "independent" directors. To be considered independent by our board of directors, a director must be independent in accordance with the rules and regulations of the New York Stock Exchange, or NYSE, and in our board of directors' judgment, the director must not have a material relationship with Ameresco (either directly or as a partner, shareholder or officer of an organization that has a relationship with Ameresco). Our board of directors has established corporate governance guidelines to assist it in determining whether a director has such a material relationship. Under these guidelines, a director is not considered to have a material relationship with Ameresco if he or she is independent under NYSE rules and regulations, and he or she:
is an executive officer of another company which is indebted to us or to which we are indebted, unless the total amount of either company's indebtedness to the other is more than one percent of the total consolidated assets of the company he or she serves as an executive officer; or
serves as an officer, director or trustee of a tax-exempt organization, unless our discretionary contributions to such organization are more than the greater of $1 million or two percent of that organization's consolidated gross revenue.
Our board has determined that all of our directors, other than Messrs. Sakellaris and Corrsin, qualify as "independent." Neither Messrs. Sakellaris nor Corrsin is considered independent because they are employees of our company. Further, the Board has determined that each member of each of the committees of the Board is independent in accordance with the rules and regulations of the NYSE and, as applicable, Rule 10a-3(b)(1) and Rule 10C-1 under the Exchange Act. In making its independence determinations, the board considered, among other things, the requirements under NYSE rules and regulations and our corporate governance guidelines, relevant transactions between our company and entities associated with the independent directors and determined that none have any relationship with the company or other relationships that would impair the directors' independence.
Board Leadership Structure
George P. Sakellaris currently serves as both our chairman of the board and chief executive officer. Our board of directors does not have a policy regarding the separation of the roles of chairman and chief executive officer, as the board believes it is in our stockholders' best interests that we make this determination based on an assessment of the current condition of our company and composition of the board. Our board of directors believes that having Mr. Sakellaris serve in both roles is in the best interests of our stockholders at this time because it makes the best use of Mr. Sakellaris's extensive knowledge of our company and our industry, and fosters greater communication between management and the board of directors.
In light of the dual role played by Mr. Sakellaris in our corporate governance structure, we also have established a position of a lead independent director. Mr. Sutton is our lead independent director. Mr. Sutton is an independent director within the meaning of applicable NYSE rules. The duties of the lead director include the following:
chairing any meeting of our non-management or independent directors in executive session;
meeting with any director who is not adequately performing their duties as a member of our board of directors or any committee;
facilitating communications between other members of our board of directors and the chairman of our board of directors and/or the chief executive officer; however, each director is free to communicate directly with the chairman of our board of directors and with the chief executive officer;
monitoring, with the assistance of our general counsel, communications from stockholders and other interested parties and providing copies or summaries to the other directors as he considers appropriate;
working with the chairman of our board in the preparation of the agenda for each board of directors meeting and in determining the need for special meetings of the board of directors; and
otherwise consulting with the chairman of our board of directors and/or the chief executive officer on matters relating to corporate governance and the performance of our board of directors.
Risk Oversight by our Board
One of the key functions of our board of directors is informed oversight of company performance, strategy, capital allocation, succession planning, and our risk management process. Our board of directors also analyzes our company's three-year strategic plan and reviews progress towards stated goals with the executive management team on a quarterly basis. Our management is responsible for risk management on a day-to-day basis. Our board of directors as a whole oversees company risk management, and its standing committees address risks inherent in their respective areas of oversight. The quarterly meeting cadence of our board and committees supports regular senior management engagement, regular business, governance, and regulatory updates, and oversight of our enterprise risks and other key initiatives.
Our board is responsible for monitoring and assessing strategic risk exposure and overall enterprise risk exposure.
Our board reviews management updates quarterly and holds a strategic session with management annually. These updates and sessions also cover topics such as capital allocation, succession planning, cybersecurity and environmental, social and governance ("ESG") matters.
The chair of each of our board committees provides a report to the full board of matters covered at the committee level.
