You are cordially invited to attend the 2021 annual meeting of stockholders of Aspen Aerogels, Inc. to be held at 9:00 a.m. Eastern Time on Thursday, June 1, 2021.

At the 2021 annual meeting, two persons will be elected to our board of directors.

Our board of directors recommends the election of the two nominees to our board of directors and a vote in favor of proposals (i), (ii) and (iii). Such other business will be transacted as may properly come before the annual meeting.

Under Securities and Exchange Commission rules that allow companies to furnish proxy materials to stockholders over the Internet, we have elected to deliver our proxy materials to the majority of our stockholders over the Internet. This delivery process allows us to provide stockholders with the information they need, while at the same time conserving natural resources and lowering the cost of delivery. On or about April 19, 2021, we will send to our stockholders a Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access our proxy statement for our 2021 annual meeting of stockholders and our 2020 annual report to stockholders. The Notice also provides instructions on how to vote online or by telephone and includes instructions on how to receive a paper copy of the proxy materials by mail.

We hope you will be able to attend the annual meeting. Whether you plan to attend the annual meeting or not, it is important that you cast your vote either virtually at the time of the annual meeting or by proxy. You may vote over the Internet as well as by telephone or by mail. When you have finished reading the proxy statement, you are urged to vote in accordance with the instructions set forth in the proxy statement. We encourage you to vote by proxy so that your shares will be represented and voted at the meeting, whether or not you can attend.

PROXY STATEMENT FOR THE ASPEN AEROGELS, INC.

2020 ANNUAL MEETING OF STOCKHOLDERS TO BE HELD ON JUNE 1, 2021

This proxy statement, along with the accompanying notice of 2021 annual meeting of stockholders, contains information about the 2021 annual meeting of stockholders of Aspen Aerogels, Inc., including any adjournments or postponements of the annual meeting. We are holding the annual meeting at 9:00 a.m., Eastern Time, on Thursday, June 1, 2021. As a result of the public health and travel guidance due to the COVID-19 pandemic, this year’s annual meeting will be conducted solely via live audio webcast on the Internet.

You will not be able to attend the annual meeting in person.

In this proxy statement, we refer to Aspen Aerogels, Inc. as “Aspen Aerogels,” “the Company,” “we” and “us.”

This proxy statement relates to the solicitation of proxies by our board of directors for use at the annual meeting.

On or about April 19, 2021, we intend to begin sending to our stockholders entitled to vote the Important Notice Regarding the Availability of Proxy Materials containing instructions on how to access our proxy statement for the 2021 annual meeting of stockholders and our 2020 annual report.

IMPORTANT INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

Why is the Company Soliciting My Proxy?

The board of directors of Aspen Aerogels is soliciting your proxy to vote at the 2021 Annual Meeting of Stockholders to be held virtually via live audio webcast, on Thursday, June 1, 2021 at 9:00 a.m. Eastern Time and any adjournments or postponements of the meeting, which we refer to as the annual meeting. This proxy statement along with the accompanying Notice of 2021 Annual Meeting of Stockholders summarizes the purposes of the meeting and the information you need to know to vote at the annual meeting.

We have made available to you on the Internet or have sent you this proxy statement, the Notice of Annual Meeting of Stockholders, the proxy card and a copy of our annual report on Form 10-K for the fiscal year ended December 31, 2020 because you owned shares of our common stock on April 5, 2021(“Record Date”). We will commence distribution of the Important Notice Regarding the Availability of Proxy Materials, which we refer to throughout this proxy statement as the Notice, and, if applicable, the proxy materials, to stockholders on or about April 19, 2021.

Why Did I Receive a Notice in the Mail Regarding the Internet Availability of Proxy Materials Instead of a Full Set of Proxy Materials?

As permitted by the rules of the U.S. Securities and Exchange Commission, or the SEC, we may furnish our proxy materials to our stockholders by providing access to such documents on the Internet, rather than mailing printed copies of these materials to each stockholder. Most stockholders will not receive printed copies of the proxy materials unless they request them. We believe that this process should expedite stockholders’ receipt of proxy materials, lower the costs of the annual meeting and help to conserve natural resources. If you received the Notice by mail or electronically, you will not receive a printed or email copy of the proxy materials, unless you request one by following the instructions included in the Notice. Instead, the Notice instructs you as to how you may access and review all of the proxy materials and submit your proxy on the Internet. If you requested a paper copy of the proxy materials, you may authorize the voting of your shares by following the instructions on the proxy card, in addition to the other methods of voting described in this proxy statement.

Why Are You Holding a Virtual Annual Meeting?

Due to the public health impact of the COVID-19 pandemic and to support the health and well-being of our stockholders, directors, officers and other participants, our 2021 Annual Meeting will be held in a virtual meeting format only. We have designed our virtual format to enhance, rather than constrain, stockholder access, participation and communication. For example, the virtual format allows stockholders to communicate with us in advance of, and during, the annual meeting so they can submit questions to our board of directors or management, as time permits. We will evaluate the effectiveness of the 2021 annual meeting and review other circumstances in 2022 to decide whether we will hold an in-person or a virtual annual meeting in 2022.

What happens if There Are Technical Difficulties during the Annual Meeting?

We will have technicians ready to assist you with any technical difficulties you may have accessing the virtual annual meeting, voting at the annual meeting or submitting questions at the annual meeting. If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the Virtual Shareholder Meeting login page.

Who Can Vote?

Only stockholders who owned our common stock at the close of business on April 5, 2021 are entitled to vote at the annual meeting. On this Record Date, there were 28,345,159 shares of our common stock outstanding and entitled to vote. Our common stock is our only class of voting stock.

If on the Record Date your shares of our common stock were registered directly in your name with our transfer agent, Computershare Trust Company, N.A., then you are a stockholder of record.

If on the Record Date your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and the Notice is being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You are also invited to attend the annual meeting. However, since 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 from your broker or other agent.

You do not need to attend the annual meeting to vote your shares. Shares represented by valid proxies, received in time for the annual meeting and not revoked prior to the annual meeting, will be voted at the annual meeting. For instructions on how to change or revoke your proxy, see “May I Change or Revoke My Proxy?” below.

How Many Votes Do I Have?

Each share of our common stock that you own entitles you to one vote.

How Do I Vote?

Whether you plan to attend the annual meeting or not, we urge you to vote by proxy. All shares represented by valid proxies that we receive through this solicitation, and that are not revoked, will be voted in accordance with your instructions on the proxy card or as instructed via the Internet or telephone. You may specify whether your shares should be voted FOR or WITHHELD for each nominee for director, and whether your shares should be voted FOR, AGAINST or ABSTAIN with respect to the other proposals. If you properly submit a proxy without giving specific voting instructions, your shares will be voted in accordance with our board of directors’ recommendations as noted below. Voting by proxy will not affect your right to attend the annual meeting. If your shares are registered directly in your name through our stock transfer agent, Computershare Trust Company, N.A., or you have stock certificates registered in your name, you may vote:

•

By Internet or by telephone. Follow the instructions included in the Notice or, if you received printed materials, in the proxy card to vote over the Internet or by telephone.

•

By mail. If you received a proxy card by mail, you can vote by mail by completing, signing, dating and returning the proxy card as instructed on the card. If you sign the proxy card but do not specify how you want your shares voted, they will be voted in accordance with our board of directors’ recommendations as noted below.

•

At the time of the virtual meeting. If you attend the virtual meeting, you may vote your shares online at the time of the meeting.

Telephone and Internet voting facilities for stockholders of record will be available 24 hours a day and will close at 11:59 p.m. Eastern Time on May 31, 2021.

If your shares are held in “street name” (held in the name of a bank, broker or other holder of record), you will receive instructions from the holder of record. You must follow the instructions of the holder of record in order for your shares to be voted. Telephone and Internet voting also will be offered to stockholders owning shares through certain banks and brokers. If your shares are not registered in your own name and you plan to vote your shares at the time of the virtual annual meeting, you should contact your broker or agent to obtain a legal proxy or broker’s proxy card and vote your shares online at the time of the meeting.

How Does the Board of Directors Recommend That I Vote on the Proposals?

The board of directors recommends that you vote as follows:

•

“FOR” the election of the nominees for director;

•

“FOR” the ratification of the appointment of KPMG LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2021; and

•

“FOR” the advisory vote to approve the compensation of the named executive officers, as disclosed in this Proxy Statement.

If any other matter is presented at the annual meeting, your proxy provides that your shares will be voted by one or both of the proxy holders listed in the proxy in accordance with his or their best judgment. At the time this proxy statement was first made available, we knew of no matters that needed to be acted on at the annual meeting, other than those discussed in this proxy statement.

May I Change or Revoke My Proxy?

If you give us your proxy, you may change or revoke it at any time before the annual meeting. You may change or revoke your proxy in any one of the following ways:

•

if you received a proxy card, by signing a new proxy card with a date later than your previously delivered proxy and submitting it as instructed above;

•

by re-voting by Internet or by telephone as instructed above;

•

by notifying Aspen Aerogels’ Secretary in writing before the annual meeting that you have revoked your proxy; or

•

by attending the annual meeting and voting virtually. Attending the annual meeting virtually will not in and of itself revoke a previously submitted proxy. You must specifically request at the annual meeting that it be revoked.

Your most current vote, whether by telephone, Internet or proxy card is the vote that will be counted.

What if I Receive More Than One Notice or Proxy Card?

You may receive more than one Notice or proxy card if you hold shares of our common stock in more than one account, which may be in registered form or held in street name. Please vote in the manner described above under “How Do I Vote?” for each account to ensure that all of your shares are voted.

Will My Shares be Voted if I Do Not Vote?

If your shares are registered in your name or if you have stock certificates, they will not be counted if you do not vote as described above under “How Do I Vote?” If your shares are held in street name and you do not provide voting instructions to the bank, broker or other nominee that holds your shares as described above, the bank, broker or other nominee that holds your shares has the authority to vote your unvoted shares only on the ratification of the appointment of our independent registered public accounting firm (Proposal 2 of this proxy statement) without receiving instructions from you. Therefore, we encourage you to provide voting instructions to your bank, broker or other nominee. This ensures your shares will be voted at the annual meeting and in the manner you desire. A “broker non-vote” will occur if your broker cannot vote your shares on a particular matter because it has not received instructions from you and does not have discretionary voting authority on that matter or because your broker chooses not to vote on a matter for which it does have discretionary voting authority.

Your bank, broker or other nominee does not have the ability to vote your uninstructed shares in the election of directors. Therefore, if you hold your shares in street name, it is critical that you cast your vote if you want your vote to be counted for Proposal Nos. 1 and 3 of this proxy statement.

What Vote is Required to Approve Each Proposal and How are Votes Counted?

	Proposal 1: Elect Directors	The nominees for director who receive the most votes (also known as a “plurality” of the votes cast) will be elected. You may vote either FOR all of the nominees, WITHHOLD your vote from all of the nominees or WITHHOLD your vote from any one or more of the nominees. Votes that are withheld will not be included in the vote tally for the election of the directors. Brokerage firms do not have authority to vote customers’ unvoted shares held by the firms in street name for the election of the directors. As a result, any shares not voted by a customer will be treated as a broker non-vote. Such broker non-votes will have no effect on the results of this vote.

	Proposal 2: Ratify Appointment of Independent Registered Public Accounting Firm	The affirmative vote of a majority of the shares cast affirmatively or negatively for this proposal is required to ratify the appointment of our independent registered public accounting firm. Abstentions will have no effect on the results of this vote. Brokerage firms have authority to vote customers’ unvoted shares held by the firms in street name on this proposal. If a broker does not exercise this authority, such broker non-votes will have no effect on the results of this vote. We are not required to obtain the approval of our stockholders to appoint our independent registered public accounting firm. However, if our stockholders do not ratify the appointment of KPMG LLP as our independent registered public accounting firm for 2021, the audit committee of our board of directors will reconsider its appointment.

	Proposal 3: Approve, on an advisory basis, the compensation of the named executive officers, as disclosed in this Proxy Statement	The affirmative vote of a majority of the shares cast affirmatively or negatively for this proposal decides the result of the advisory vote. Abstentions will have no effect on the outcome of the proposal. Brokerage firms do not have authority to vote customers’ unvoted shares held by the firms in street name on this proposal. As a result, any shares not voted by a customer will be treated as a broker non-vote. Such broker non-votes will have no effect on the results of this vote.

Is Voting Confidential?

We will keep all the proxies, ballots and voting tabulations private. We only let our Inspectors of Election, representatives of Broadridge Investor Communication Solutions, Inc., examine these documents. Management will not know how you voted on a specific proposal unless it is necessary to meet legal requirements. We will, however, forward to management any written comments you make on the proxy card or that you otherwise provide.

Where Can I Find the Voting Results of the Annual Meeting?

The preliminary voting results will be announced at the annual meeting, and we will publish preliminary, or final results if available, in a Current Report on Form 8-K within four business days of the annual meeting. If final results are unavailable at the time we file the Form 8-K, then we will file an amended report on Form 8-K to disclose the final voting results within four business days after the final voting results are known.

What Are the Costs of Soliciting these Proxies?

We will pay all of the costs of soliciting these proxies. Our directors and employees may solicit proxies by telephone, fax or email. We will pay these employees and directors no additional compensation for these services. We will ask banks, brokers and other institutions, nominees and fiduciaries to forward these proxy materials to their principals and to obtain authority to execute proxies. We will then reimburse them for their expenses.

What Constitutes a Quorum for the Annual Meeting?

The presence, at the meeting virtually or by proxy, of the holders of a majority of the voting power of all outstanding shares of our common stock entitled to vote at the annual meeting is necessary to constitute a quorum at the annual meeting. Votes of stockholders of record who are present at the annual meeting virtually or by proxy, abstentions, and broker non-votes are counted for purposes of determining whether a quorum exists.

Attending the Annual Meeting

The annual meeting will be held at 9:00 a.m. Eastern Time on Thursday, June 1, 2021. This year, our annual meeting will be held in a virtual meeting format only.

To attend the virtual annual meeting, go to https://www.virtualshareholdermeeting.com/ASPN2021 shortly before the meeting time, and follow the instructions for downloading the webcast. If you miss the annual meeting, you can view a replay of the webcast at the same location at least six months from the meeting. You need not attend the annual meeting in order to vote.

Householding of Annual Disclosure Documents

SEC rules concerning the delivery of annual disclosure documents allow us or your broker to send a single Notice or, if applicable, a single set of our proxy materials to any household at which two or more of our stockholders reside, if we or your broker believe that the stockholders are members of the same family. This practice, referred to as “householding,” benefits both you and us. It reduces the volume of duplicate information received at your household and helps to reduce our expenses. The rule applies to our Notices, annual reports, proxy statements and information statements. Once you receive notice from your broker or from us that communications to your address will be “householded,” the practice will continue until you are otherwise notified or until you revoke your consent to the practice. Stockholders who participate in householding will continue to have access to and utilize separate proxy voting instructions.

If your household received a single Notice or, if applicable, a single set of proxy materials this year, but you would prefer to receive your own copy, please contact our transfer agent, Computershare Trust Company, N.A., by calling their toll free number, 1-800-368-5948.

If you do not wish to participate in householding and would like to receive your own Notice or, if applicable, set of Aspen Aerogels proxy materials in future years, follow the instructions described below. Conversely, if you share an address with another Aspen Aerogels stockholder and together both of you would like to receive only a single Notice or, if applicable, set of proxy materials, follow these instructions:

•

If your Aspen Aerogels shares are registered in your own name, please contact our transfer agent, Computershare Trust Company, N.A., and inform them of your request by calling them at 1-800-368-5948 or writing them at Computershare Investor Services, P.O. Box 505000, Louisville, Kentucky 40233-9814.

•

If a broker or other nominee holds your Aspen Aerogels shares, please contact the broker or other nominee directly and inform them of your request. Be sure to include your name, the name of your brokerage firm and your account number.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth certain information with respect to the beneficial ownership of our common stock as of April 5, 2021 for (a) the executive officers named in the Summary Compensation Table on page 20 of this proxy statement, (b) each of our directors and director nominees, (c) all of our current directors and executive officers as a group and (d) each stockholder known by us to own beneficially more than 5% of our common stock.

Beneficial ownership is determined in accordance with the rules of the SEC and includes voting or investment power with respect to the securities. We deem shares of common stock that may be acquired by an individual or group within 60 days of April 5, 2021 pursuant to the exercise of options or warrants or the vesting of restricted stock units (“RSUs”) to be outstanding for the purpose of computing the percentage ownership of such individual or group, but are not deemed to be outstanding for the purpose of computing the percentage ownership of any other person shown in the table.

Except as indicated in footnotes to this table, we believe that the stockholders named in this table have sole voting and investment power with respect to all shares of common stock shown to be beneficially owned by them based on information provided to us by these stockholders. Percentage of ownership is based on 28,345,159 shares of common stock outstanding on April 5, 2021.

Director Independence

Our board of directors has reviewed the materiality of any relationship that each of our directors has with Aspen Aerogels, either directly or indirectly. Based upon this review, our board has determined that all of our directors other than Donald R. Young, our President and Chief Executive Officer, are “independent directors” as defined by the New York Stock Exchange.

Committees of the Board of Directors and Meetings

Meeting Attendance. During the fiscal year ended December 31, 2020, there were seven meetings of our board of directors, and the various committees of the board met a total of 21 times. No director attended fewer than 75% of the total number of meetings of the board and of committees of the board on which he or she served during fiscal year 2020. The board has adopted a policy under which each member of the board is strongly encouraged but not required to attend each annual meeting of our stockholders. All of our directors attended the annual meeting of our stockholders held in 2020.

Audit Committee. Our audit committee met nine times during fiscal year 2020. This committee currently has three members, Richard F. Reilly (chair), Rebecca B. Blalock and Mark L. Noetzel. Our audit committee’s role and responsibilities are set forth in the audit committee’s written charter and include the authority to retain and terminate the services of our independent registered public accounting firm. In addition, the audit committee reviews our annual and quarterly financial statements, considers matters relating to accounting policy and internal controls and reviews the scope of annual audits. All members of the audit committee satisfy the current independence standards promulgated by the SEC and by the New York Stock Exchange, as such standards apply specifically to members of audit committees. Our board of directors has determined that Mr. Reilly is an “audit committee financial expert,” as the SEC has defined that term in Item 407 of Regulation S-K.

Our audit committee is authorized to, among other matters:

•

approve and retain the independent registered public accounting firm to conduct the annual audit of our financial statements;

•

review the proposed scope and results of the audit;

•

review accounting and financial controls with the independent registered public accounting firm and our financial and accounting staff;

•

review and approve transactions between us and our directors, officers and affiliates;

•

recognize and prevent prohibited non-audit services;

•

establish procedures for complaints received by us regarding accounting matters and any other complaints alleging a violation of our code of business conduct and ethics;

•

oversee internal audit functions;

•

review and evaluate our policies and procedures with respect to risk assessment and risk management; and

•

prepare the report of the audit committee that the rules of the SEC require to be included in our annual meeting proxy statement.

Our audit committee typically meets quarterly and with greater frequency as necessary. The agenda for each meeting is set by the chair of the audit committee in consultation with the Chief Executive Officer and Chief Financial Officer. The audit committee meets regularly in executive session. However, from time to time, various members of management, and employees, outside advisors or consultants may be invited by the audit committee to make presentations, to provide financial, background information or advice, or to otherwise participate in audit committee meetings.

Please also see the report of the audit committee set forth elsewhere in this proxy statement.

A copy of the audit committee’s written charter is publicly available in the “Investors” section of our website at www.aerogel.com.

Compensation and Leadership Development Committee. Our compensation and leadership development committee (hereafter also referred to as our “compensation committee”) met eight times during fiscal 2020. This committee currently has three members, Robert M. Gervis (chair), William P. Noglows and Steven R. Mitchell. Our compensation committee’s role and responsibilities are set forth in the compensation committee’s written charter and includes reviewing, approving and making recommendations regarding our compensation policies, practices and procedures to ensure that legal and fiduciary responsibilities of the board of directors are carried out and that such policies, practices and procedures contribute to our success. Our compensation committee also administers our 2014 Employee, Director and Consultant Equity Incentive Plan (“2014 Plan”) and our employee cash bonus plan. The compensation committee is responsible for the determination of the compensation of our executive officers other than our Chief Executive Officer. The compensation of our Chief Executive Officer is determined by our board of directors upon the recommendation of our compensation committee. All members of the compensation committee qualify as independent under the definition promulgated by the New York Stock Exchange.

Our compensation committee is authorized to, among other matters:

•

review and recommend compensation arrangements for management;

•

establish and review general compensation policies with the objective to attract and retain superior talent, to reward individual performance and to achieve our financial goals;

•

administer our equity incentive plans;

•

ensure appropriate leadership development and succession planning is in place;

•

oversee the evaluation of management; and

•

if applicable, prepare the report of the compensation committee that the rules of the SEC require to be included in our annual meeting proxy statement.

Our compensation committee typically meets quarterly and with greater frequency if necessary. The agenda for each meeting is set by the chair of the compensation committee in consultation with the Chief Executive Officer. The compensation committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the compensation committee to make presentations, to provide financial or other background information or advice, or to otherwise participate in compensation committee meetings. The Chief Executive Officer does not participate in and is not present during any deliberations or determinations of the board of directors or the compensation committee regarding his compensation.

The compensation committee has the sole authority to obtain, at the expense of the Company, advice and assistance from compensation consultants, legal counsel, experts and other advisors that the compensation committee deems advisable in the performance of its duties. The compensation committee has the sole authority to approve any such consultants’ or advisors’ fees and other retention terms. The compensation committee may select any such consultant, counsel, expert or advisor to the compensation committee, only after taking into consideration factors that bear upon the advisor’s independence. The compensation committee has engaged Meridian Compensation Partners, LLC (“Meridian”) as its compensation consultant since 2014. The compensation committee assessed the independence of Meridian pursuant to SEC rules and other factors and concluded that Meridian’s work for the compensation committee does not raise any conflict of interest nor affect its independence.

Generally, the compensation committee’s process involves the establishment of corporate goals and objectives for the current year and determination of compensation levels. For executives other than the Chief Executive Officer, the compensation committee solicits and considers evaluations and recommendations submitted to the committee by the Chief Executive Officer. In the case of the

Chief Executive Officer, the evaluation is conducted by the compensation committee, which recommends any adjustments to his compensation levels and arrangements for approval by the board of directors. For all executives, as part of its deliberations, the compensation committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, tax and accounting information, total compensation that may become payable to executives in various hypothetical scenarios, executive stock ownership information, Company stock performance data, analyses of historical executive compensation levels and current Company-wide compensation levels and recommendations of the compensation committee’s compensation consultant, if any, including analyses of executive compensation paid at other companies.

For 2020, Meridian assisted the compensation committee in fulfilling its responsibilities under its charter, including advising on compensation packages for executive officers, compensation program design and market practices generally. The compensation committee authorized Meridian to interact with management on behalf of the compensation committee, as needed in connection with advising the compensation committee, and Meridian participates in discussions with management and, when appropriate, outside legal counsel with respect to matters under consideration by the compensation committee.

A copy of the compensation committee’s written charter is publicly available in the “Investors” section of our website at www.aerogel.com.

Nominating and Governance Committee. Our nominating and governance committee met four times during fiscal year 2020 and currently has three members, Rebecca B. Blalock (chair), Robert M. Gervis and Mark L. Noetzel. The nominating and governance committee’s role and responsibilities are set forth in the nominating and governance committee’s written charter and include evaluating and making recommendations to the full board as to the size and composition of the board and its committees, evaluating and making recommendations as to potential candidates to serve on our board of directors, and evaluating current board members’ performance.

Once identified, the nominating and governance committee will evaluate a candidate’s qualifications in accordance with our “Criteria for Nomination as a Director” appended to our nominating and governance committee’s written charter. Threshold criteria include a candidate’s personal integrity and sound judgment, business and professional skills and experience, independence, knowledge of our industry, possible conflicts of interest, diversity, the extent to which the candidate would fill a present need on the board, and concern for the long-term interests of our stockholders.

If a stockholder wishes to propose a candidate for consideration as a nominee for election to our board of directors, the stockholder must follow the procedures described in our restated bylaws and in “Stockholder Proposals and Nominations for Director” at the end of this proxy statement. In general, persons recommended by stockholders will be considered in accordance with our “Policies and Procedures for Shareholders Submitting Nominating Recommendations” appended to our nominating and governance committee’s written charter. All stockholder recommendations for proposed director nominees must be addressed in writing to the nominating and governance committee, in care of our Secretary, at our principal offices and must be received by the deadlines set forth in this proxy statement under the heading “Stockholder Proposals and Nominations for Director.” The recommendation must be accompanied by the following information concerning each stockholder making the recommendation and the beneficial owner, if any, on whose behalf the nominations is made:

Compensation Committee Interlocks and Insider Participation

During our last fiscal year, the members of our compensation committee included Robert M. Gervis (chair), Steven R. Mitchell and William P. Noglows. No member of our compensation committee has at any time been an employee of ours. None of our executive officers serves as a member of another entity’s board of directors or compensation committee that has one or more executive officers serving as a member of our board of directors or compensation committee.

Board Leadership Structure and Role in Risk Oversight

The positions of Chairman of the Board and Chief Executive Officer are presently separated at our Company. We believe that separating these positions allows our Chief Executive Officer to focus on our day-to-day business, while allowing our Chairman of the Board to lead the board of directors in its fundamental role of providing advice to, and independent oversight of, management. Our board of directors recognizes the time, effort and energy that the Chief Executive Officer is required to devote to his position in the current business environment, as well as the commitment required to serve as our Chairman, particularly as the board of directors’ oversight responsibilities continue to grow. Our board of directors also believes that this structure ensures a greater role for the independent directors in the oversight of our Company and active participation of the independent directors in setting agendas and establishing priorities and procedures for the work of our board of directors. Our board of directors believes its administration of its risk oversight function has not affected its leadership structure.

Our board of directors administers its risk oversight function directly and through its committees. The audit committee receives regular reports from members of senior management on areas of material risk to the Company, including operational, financial, legal, regulatory, strategic and reputational risks. The audit committee also periodically reviews our enterprise risk management program.

EXECUTIVE COMPENSATION AND RELATED MATTERS

Compensation Overview

We are a “smaller reporting company” as such term is defined by the Securities and Exchange Commission. In accordance with relevant SEC rules and guidance, we have elected, with respect to the disclosures relating to executive compensation to comply with the disclosure requirements applicable to smaller reporting companies. This “Compensation Overview” section discusses the compensation programs and policies for our executive officers and the roles of our Compensation and Leadership Development Committee, or the compensation committee, and our board in the design and administration of these programs and policies, including specific compensation decisions in connection with our executive officers, including our named executive officers.

Our compensation committee has the sole authority and responsibility to review and determine, or recommend to the board for approval in the case of our Chief Executive Officer, the compensation of each of our named executive officers. Our compensation committee also considers the design and effectiveness of the compensation program for our other executive officers and approves the final compensation package, employment agreements and stock awards and option grants for all of our executive officers, except our Chief Executive Officer, whose compensation is approved by the board upon the recommendation of the compensation committee. Our compensation committee is composed entirely of independent directors who have never served as officers of the Company.

Set forth below is a discussion of the policies and decisions that shape our executive compensation program, including the specific objectives and elements. Information regarding director compensation is included under the heading “Director Compensation” below.

General Executive Compensation Philosophy and Principles

The objective of our executive compensation program is to attract, retain and motivate talented executives who are critical for our continued growth and success of building a profitable business and to align the interests of these executives with those of our stockholders. To achieve this objective, besides annual base salaries, our executive compensation program utilizes a combination of annual incentives through cash bonuses based on a mix of pre-determined criteria and long-term incentives through equity-based compensation. In establishing overall executive compensation levels, our compensation committee considers a number of criteria, including the executive’s scope of responsibilities, prior and current period of performance, attainment of overall company performance objectives and retention concerns. The overall compensation program is conceived to be generally competitive with the market median of peer companies with no specific percentile being targeted. The program combines the base salary with at-risk elements to achieve the Company’s mix of pay objectives.

The Role of our Compensation Committee

Generally, our compensation committee designs and administers the executive compensation program with the help of the management and an independent compensation consultant. In connection with the compensation of our Chief Executive Officer, our compensation committee further recommends the overall and specific elements to our board for consideration and final determination. While the compensation committee addresses the matters related to its responsibilities under its charter throughout the year, annual reviews and, as appropriate, modifications of compensation arrangements for executive officers typically take place during a period starting from the last quarter of the prior fiscal year through the first quarter of the current fiscal year.

While the compensation committee or the board in the case of our Chief Executive Officer, ultimately makes all final decisions on executive compensation, the compensation committee engages the services of outside advisors for assistance. In 2019 and 2020, the compensation committee directly engaged Meridian Compensation Partners LLC, or Meridian, as its independent compensation consultant. The compensation committee utilized Meridian throughout these periods to provide independent, objective research, analysis, and advice and to assist the compensation committee generally in the performance of its duties. The compensation committee will typically request information and recommendations directly from the compensation consultant as it deems appropriate to structure and evaluate our executive compensation program. During these periods, the compensation committee also enlisted the assistance of the law firm of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., to administer its compensation decisions through contracts and other written documents. The compensation committee assesses the independence of its compensation consultant and law firm each year, considering the amount of fees paid to them, the policies designed to prevent conflicts of interest, any Company stock owned by the consultant or the law firm, and other factors that may be relevant to the compensation committee.

During 2015, Meridian helped the compensation committee collect and analyze data and compare all components of our compensation program for all executives, including base salary, our annual cash incentive plan and our long-term incentive plan involving equity grants, to the compensation practices of peer companies. Meridian developed a group of peer companies generally in the energy sector based on several characteristics, including, being publicly traded, relative company size (market capitalization,

revenue, number of employees) and geographic locations as well as specific responsibilities of our executives. Our compensation committee approved the peer group in 2015 and periodically reviews and, if appropriate, revises the peer group in coordination with input from our Chief Executive Officer and Meridian to ensure the group remains appropriate for the purposes of comparing executive compensation. During 2020, our peer group consisted of the following 16 companies:

2020 Peer Group Companies
Ballard Power Systems, Inc.	FuelCell Energy, Inc.	Orion Energy Systems, Inc.
Chase Corporation	Graham Corporation	Preformed Line Products Company
Core Molding Technologies, Inc.	Lydall, Inc.	Thermon Group Holdings, Inc.
Orbital Energy Group, Inc.⁽¹⁾	Natural Gas Services Group, Inc.	Trecora Resources
Energy Recovery, Inc.	NN, Inc.
Enphase Energy, Inc.	Omega Flex, Inc.

(1)	Previously known as CUI Global, Inc.

We believe our peer group provides useful information to help us establish competitive compensation practices and allow us to set compensation levels to attract, retain and motivate a talented executive team while aligning the interest of our executives with our stockholders. Our compensation committee uses the peer group information obtained by Meridian periodically to evaluate our executive compensation practices and levels, to ensure the compensation structure is appropriately calibrated to achieve its objectives. Our peer group is subject to change over time, and we expect that the compensation committee will continue to periodically review and update the list.

Say-on-Pay Results

At our last annual meeting of stockholders in June 2020, we held a stockholder advisory vote on the fiscal year 2019 compensation of our named executive officers. This is generally referred to as a “Say-on-Pay” vote. Our stockholders approved the compensation of our named executive officers with approximately 98% of stockholder votes cast in favor of our Say-on-Pay resolution for fiscal year 2019. This stockholder feedback was considered in the Compensation Committee’s decisions on fiscal year 2020 compensation, discussed below. The Compensation Committee will monitor further stakeholder feedback, Company performance, and market developments for potential further improvements to the Company’s compensation structure for executive officers

Employees and Human Capital Resources

As of December 31, 2020, we had 290 full-time employees with 36 in research and development, 179 in manufacturing operations and supply chain, 46 in sales and marketing and 29 in general and administrative functions. Of our employees, 274 are located in the United States and 16 are located abroad.

Our human capital resources objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and new employees, advisors and consultants as a cohesive and competent team and to achieve our short and long term objectives. The principal purposes of our equity and cash incentive plans are to attract, retain and reward personnel through the granting of stock-based and cash-based compensation awards, in order to increase stockholder value and the success of our company by motivating such individuals to perform to the best of their abilities to achieve our objectives. We consider our current relationship with our employees to be of good standing. None of our employees are represented by labor unions or have collective bargaining agreements.

Main Elements of our Executive Compensation Program

Base Salary

Annual base salaries compensate our executive officers for fulfilling the requirements of their respective positions and provide them with a level of cash income predictability and stability with respect to a portion of their total compensation. We believe that the level of an executive officer’s base salary should reflect the executive’s performance, experience and breadth of responsibilities, our understanding of salaries for similar positions within our industry and any other factors relevant to that particular job. Our salaries are designed to be generally competitive with the market median of our peer group.

Base salaries are typically negotiated at the outset of an executive’s employment. Salary levels are considered annually as part of our performance review process, but also in cases including promotion or other change in the job responsibilities of an executive officer. For named executive officers, initial base salaries generally are established in connection with negotiation of an offer of employment and employment agreement. Increases in base salary have several elements. In addition to promotion and increased

responsibilities, merit and Company-wide general increases are also taken into consideration. Salaries of our named executive officers for fiscal years 2020 and 2019 are also reported in the Summary Compensation Table below.

Cash Incentive Plan

Upon the recommendation of our compensation committee, our board of directors initially approved our employee cash bonus plan in April 2012. The plan is designed to motivate and reward our executives for achieving certain corporate financial and other business performance during the upcoming fiscal year and the plan is administered by the compensation committee. The plan provides that executives are eligible to receive a cash bonus over an annual performance period based on goals established by the compensation committee which may include revenue goals, an adjusted EBITDA goal or such other performance goals established by the compensation committee from time to time. The compensation committee determines the percentage of annual base salary as target bonus for each executive, usually along with determining base salaries at the beginning of the year. Each executive receives a participation letter setting forth a percentage allocation of a target award based upon a percentage of base salary or set forth as a dollar amount. The participation letters also set forth minimum threshold achievement levels applicable to each goal and may set forth additional payments above the target award amount in the event that one or more goals are exceeded. Following completion of the performance period, the administrator determines the level of performance achieved for each goal and approves and certifies the amount of the cash payments to be made. The maximum amount of bonus that can be earned is limited to 225% of the target bonus.

Long Term Equity Incentive Plan

Our board established the 2014 Employee, Director and Consultant Equity Incentive Plan, or 2014 Stock Plan, in 2014 before our initial public offering. Our board is the administrator of the 2014 Stock Plan, which through the compensation committee charter is delegated to our compensation committee. The compensation committee, based on its annual review of compensation levels for each of our executives, determines a dollar amount value of the annual equity grants. The compensation committee also determines the mix of equity instruments, for equity grant issued pursuant to the 2014 Stock Plan, such as options to purchase our common stock, restricted stock units (“RSUs”) or restricted stock awards, as well as a vesting schedule. In recent years, the mix has been set at 50% stock options and 50% RSUs while the mix for 2020 and 2021 grants was set at 75% stock options and 25% RSUs. Except in special circumstances, time-based vesting is used. The stock options and RSUs granted in recent years vest in equal installments on an annual basis during the three years following the grant. Pursuant to our 2014 Stock Plan, the exercise price of the stock options is the closing price of our stock at New York Stock Exchange on the grant date. Similar to other components of compensation, the compensation committee recommends the equity grants for our Chief Executive Officer to our board for approval.

Other aspects of Executive Compensation

Benefits - In addition to the components described above, our executives are eligible to participate in other benefits available to all of our employees. These benefits include a 401(k) plan with a Company match element, healthcare insurance with a Company contribution to the premium, short-term and long-term disability insurance, term-life insurance, a dental plan and a vision plan.

Key policies – Our board or a committee thereof, has established stock ownership guidelines for the executives effective November 1, 2017. Additionally, our board established a compensation recoupment policy effective December 12, 2018. Our Insider Trading Policy established in June 2014 prohibits our employees, including our executive officers from engaging in certain types of hedging transactions involving our securities, specifically short sales and transactions involving straddles, collars or similar risk reduction or hedging devices.

Employment Contracts – We have entered into an executive employment agreement with our Chief Executive Officer, Mr. Young effective January 1, 2019 which was subsequently amended effective on August 1, 2019 and January 1, 2020. We have also entered into executive employment agreements with Messrs. Fairbanks and Whitaker effective January 1, 2019 which were each subsequently amended effective on January 1, 2020.

Specific Actions taken in 2020 and in early 2021 on Executive Compensation

On April 1, 2020, in light of the COVID-19 pandemic and the ensuing economic uncertainty, the board, upon the recommendation of our Chief Executive Officer, determined not to implement any increase in base salary of our executive officers, previously approved by the board to take effect in April 2020 and reduced the base salary of our executive officers to 95% of the respective 2019 base salaries (“2020 Reduction”), each upon the written consent of each of our executive officers. Effective February 20, 2021, the board and our compensation committee reversed the 2020 Reduction in base salaries of, respectively, our chief executive officer and other executive officers along with restoration of any annual merit increase considerations. Accordingly, effective April 1, 2021, Mr. Young’s annual base salary was set at $515,000. Base salaries of the other two named executive officers, Messrs. Fairbanks and Whitaker were set at $300,005 and $347,866, respectively. The cash incentive target bonus for fiscal year 2021 for Messrs. Young, Fairbanks and Whitaker were set at 110%, 55% and 55% of their respective year-end base salaries, respectively. The cash

bonus earned and paid for fiscal years 2020 and 2019 are found in the “Non-Equity Incentive Plan” column of the Summary Compensation Table. Similarly, the equity grants for fiscal years 2020 and 2019 are found in the “Stock Awards” and “Options Awards” columns of the Summary Compensation Table.

Special CEO Compensation arrangements

In addition to the compensation elements discussed above, we have two special arrangements related to the compensation of our Chief Executive Officer. In 2015, our board, upon the recommendation of the compensation committee, awarded certain special equity awards to Mr. Young in lieu of annual grants in 2015 and 2016. Additional details of this award are found under the section below, titled “Narrative Disclosure to Summary Compensation Table - 2017 and 2018 Modifications to 2015 Special Equity Incentive Grants.” In November 2018, our board approved a special cash bonus arrangement for our Chief Executive Officer in connection with certain change of control transactions involving the Company. The details of such arrangement are described in the section below, titled “Severance and Retirement Benefits - Potential Payments Upon Termination or Change of Control.”

Compensation Recoupment Policy

In December 2018, our board adopted a compensation recoupment policy, which applies to certain designated employees, including our Chief Executive Officer and Chief Financial Officer. The policy permits us to recoup incentive compensation paid to the designated employees in the event of an accounting restatement of any of the unaudited interim quarterly or audited annual consolidated financial statements of the Company due to significant non-compliance with financial reporting requirements under applicable laws, rules and regulations or upon certain forms of misconduct by a designated employee.
