Dear Stockholder:

I am pleased to invite you to attend the Annual Meeting of Stockholders of Inogen, Inc. (“Inogen”), which will be held on June 5, 2024 at 10:00 a.m. Pacific Time as a virtual meeting. The Annual Meeting of Stockholders (together with any postponements, adjournments or continuations thereof, the “Annual Meeting”) will be held in a virtual meeting format only. You will be able to attend the meeting, vote and submit your questions via the Internet at www.virtualshareholdermeeting.com/INGN2024. You will not be able to attend the virtual Annual Meeting physically in person.

At the Annual Meeting, we will ask you to consider the following proposals:

Our Board of Directors has fixed the close of business on April 8, 2024 as the record date for the Annual Meeting. Only stockholders of record on April 8, 2024 are entitled to notice of and to vote at the Annual Meeting. Further information regarding voting rights and the matters to be voted upon is presented in the accompanying proxy statement.

We are pleased to be furnishing proxy materials to stockholders primarily over the Internet for our Annual Meeting. Consequently, most stockholders will not receive paper copies of our proxy materials. We will instead send to our stockholders a Notice of Internet Availability of Proxy Materials. We believe that this process expedites stockholders’ receipt of proxy materials, lowers the costs of our Annual Meeting, and conserves natural resources.

On or about April 18, 2024, we expect to mail to our stockholders a Notice of Internet Availability of Proxy Materials containing instructions on how to access our proxy statement for our Annual Meeting and our annual report to stockholders (“Annual Report”). The Notice of Internet Availability of Proxy Materials also includes instructions on how you can vote using the Internet and how you can request and receive, free of charge, a printed copy of our proxy materials. Our proxy statement and our 2023 Annual Report can be accessed directly at the following Internet address: http://www.proxyvote.com by entering the control number located on your proxy card. All stockholders who do not receive a Notice of Internet Availability of Proxy Materials will receive a paper copy of the proxy materials by mail.

YOUR VOTE IS IMPORTANT. Whether or not you plan to attend the virtual Annual Meeting of Stockholders, we urge you to submit your vote via the Internet, telephone or mail.

On behalf of the Board of Directors, I would like to express our appreciation for your interest in Inogen.

Sincerely,

Kevin R.M. Smith

PROXY STATEMENT

FOR 2024 ANNUAL MEETING OF STOCKHOLDERS

To Be Held Virtually on June 5, 2024 at 10:00 a.m. Pacific Time

This proxy statement and the accompanying form of proxy are furnished in connection with the solicitation of proxies by our Board of Directors (the “Board”) of Inogen, Inc. (“Inogen” or the “Company”) for use at our 2024 Annual Meeting of Stockholders, and any postponements, adjournments or continuations thereof (the “Annual Meeting”). The Annual Meeting will be held virtually via live webcast on the Internet at www.virtualshareholdermeeting.com/INGN2024 on Wednesday, June 5, 2024 at 10:00 a.m. Pacific Time in a virtual meeting format only. You will not be able to attend the Annual Meeting physically in person. The live webcast of the Annual Meeting can be accessed by stockholders on the day of the meeting at www.virtualshareholdermeeting.com/INGN2024. If you have difficulty accessing the virtual meeting during the check-in or meeting time, a technical assistance phone number will be made available on the virtual meeting registration page 15 minutes prior to the start time of the meeting. On or about April 18, 2024, we expect to mail to our stockholders a Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access our proxy statement for our Annual Meeting and our annual report to stockholders (“Annual Report”). Information contained on, or that can be accessed through, our website is not intended to be incorporated by reference into this proxy statement and references to our website address in this proxy statement are inactive textual references only.

QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING

The information provided in the “question and answer” format below addresses certain frequently asked questions but is not intended to be a summary of all matters contained in this proxy statement. Please read the entire proxy statement carefully before voting your shares.

What is a proxy?

A proxy is your legal designation of another person to vote the stock you own. The person you designate is your “proxy,” and you give the proxy authority to vote your shares by submitting the accompanying proxy card or voting by telephone or over the Internet. We have designated our Chief Executive Officer and President, Kevin R.M. Smith, and our Executive Vice President, General Counsel and Corporate Secretary, Jason Somer, to serve as proxies for the Annual Meeting.

Why am I receiving these materials?

The Board of Inogen is providing these proxy materials to you in connection with the Board’s solicitation of proxies for use at the virtual Annual Meeting (and at any adjournment or postponement of such meeting), which will take place virtually via the Internet on June 5, 2024. Stockholders are invited to attend the virtual Annual Meeting and are requested to vote on the proposals described in this proxy statement. This proxy statement and the accompanying proxy card are being made available on or about April 18, 2024 in connection with the solicitation of proxies on behalf of the Board.

How do I get electronic access to the proxy materials?

The notice of annual meeting, proxy statement, and Annual Report are available by visiting www.proxyvote.com and typing in the control number as set forth (i) on the proxy card (for stockholders of record), or (ii) on the voting instruction form (for individuals who hold shares through a broker, bank, trustee, or nominee).

What information is contained in these materials?

The information included in this proxy statement relates to the proposals to be voted on at the Annual Meeting, the voting process, the compensation of our most highly paid executive officers and our directors, and certain other required information. Inogen’s Annual Report, which includes our audited financial statements, is being made available along with this proxy statement.

What proposals will be voted on at the Annual Meeting?

The proposals scheduled to be voted on at the Annual Meeting include:

How does our Board recommend that I vote?

Our Board recommends that you vote:

Will there be any other items of business on the agenda?

If any other items of business or other matters are properly brought before the Annual Meeting, your proxy gives discretionary authority to the persons named on the proxy card with respect to those items of business or other matters. The persons named on the proxy card intend to vote the proxy in accordance with their best judgment. Our Board does not intend to bring any other matters to be voted on at the Annual Meeting, and we are not currently aware of any matters that may be properly presented by others for consideration at the Annual Meeting.

Who is entitled to vote at the Annual Meeting?

Holders of our common stock at the close of business on April 8, 2024, the record date for the Annual Meeting (the “Record Date”), are entitled to notice of and to vote at the Annual Meeting. Each stockholder is entitled to one vote for each share of our common stock held as of the Record Date. As of the Record Date, there were 23,546,871 shares of common stock outstanding and entitled to vote. Stockholders are not permitted to cumulate votes with respect to the election of directors. The shares you are entitled to vote include shares that are (1) held of record directly in your name, and (2) held for you as the beneficial owner through a broker, bank or other nominee.

What is the difference between holding shares as a stockholder of record and as a beneficial owner?

Stockholder of Record: Shares Registered in Your Name. If, at the close of business on the Record Date, your shares were registered directly in your name with Computershare Trust Company, N.A., our transfer agent, then you are considered the stockholder of record with respect to those shares. As the stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or to vote virtually at the Annual Meeting.

Beneficial Owners: Shares Registered in the Name of a Broker, Bank or Other Nominee. If, at the close of business on the Record Date, your shares were held, not in your name, but rather in a stock brokerage account or by a bank or other nominee on your behalf, then you are considered the beneficial owner of shares held in “street name.” As the beneficial owner, you have the right to direct your broker, bank or other nominee how to vote your shares by following the voting instructions your broker, bank or other nominee provides. If you do not provide your broker, bank or other nominee with instructions on how to vote your shares, your broker, bank or other nominee may, in its discretion, vote your shares with respect to routine matters but may not vote your shares with respect to any non-routine matters. Please see “What if I do not specify how my shares are to be voted?” below for additional information.

Do I have to do anything in advance if I plan to attend the virtual Annual Meeting?

Stockholder of Record: Shares Registered in Your Name. If you were a stockholder of record at the close of business on the Record Date, you do not need to do anything in advance to attend and/or vote your shares at the virtual Annual Meeting.

Beneficial Owners: Shares Registered in the Name of a Broker, Bank or Other Nominee. If you were a beneficial owner at the close of business on the Record Date, you may not vote your shares at the virtual Annual Meeting unless you obtain a “legal proxy” from your broker, bank or other nominee who is the stockholder of record with respect to your shares. You may still attend the Annual Meeting even if you do not have a legal proxy.

To access, participate in, and vote at the virtual Annual Meeting at www.virtualshareholdermeeting.com/INGN2024, you must enter the 16-digit control number found on your proxy card, voting instruction form or notice that you previously received or, if you were a beneficial owner at the close of business on the Record Date, located in the proxy materials you receive from your broker. 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 login page for the Annual Meeting 15 minutes prior to the start of the meeting. After successfully entering your 16-digit control number, you may vote during the Annual Meeting and submit questions by following the instructions available on the meeting website.

How can I contact Inogen’s transfer agent?

You may contact our transfer agent by writing Computershare Investor Services, P.O. Box 43078, Providence, RI 02940-3078, by telephoning (877) 373-6374 or (781) 575-2879 (International), or via its Investor Center at www.computershare.com/investor.

Why is the Annual Meeting being held virtually?

We have decided to conduct the Annual Meeting on a virtual basis because we believe it will be more beneficial than holding a live meeting as we are able to embrace the latest technology to provide ease of access and real-time communication, while reducing the environmental impact and costs associated with an in-person meeting. We believe that by hosting our Annual Meeting virtually, our stockholders will be provided the same rights and opportunities to participate as they would at an in-person meeting, while offering a greater level of flexibility for many of our stockholders who may not be able to attend the Annual Meeting in person.

The 2024 Annual Meeting will be held as a virtual meeting format only. You will not be able to attend the Annual Meeting physically in person. The live webcast of the Annual Meeting can be accessed by stockholders on the day of the meeting at www.virtualshareholdermeeting.com/INGN2024. If you have difficulty accessing the virtual meeting during the check-in or meeting time, a technical assistance phone number will be made available on the virtual meeting registration page 15 minutes prior to the start time of the meeting.

How do I vote and what are the voting deadlines?

Stockholder of Record: Shares Registered in Your Name. If you are a stockholder of record, you can vote in one of the following ways:

Beneficial Owners: Shares Registered in the Name of a Broker, Bank or Other Nominee. If you are the beneficial owner of shares held of record by a broker, bank or other nominee, you will receive voting instructions from your broker, bank or other nominee. You must follow the voting instructions provided by your broker, bank or other nominee in order to instruct your broker, bank or other nominee how to vote your shares. The availability of Internet and telephone voting options will depend on the voting process of your broker, bank or other nominee. As discussed above, if you are a beneficial owner, you may not vote your shares virtually at the Annual Meeting unless you obtain a legal proxy from your broker, bank or other nominee.

Can I change my vote or revoke my proxy?

Stockholder of Record: Shares Registered in Your Name. If you are a stockholder of record, you may revoke your proxy or change your proxy instructions at any time before the Annual Meeting by:

Attendance at the Annual Meeting will not cause your previously granted proxy to be revoked unless you specifically so request or vote virtually at the Annual Meeting.

Beneficial Owners: Shares Registered in the Name of a Broker, Bank or Other Nominee. If you are the beneficial owner of your shares, you must contact the broker, bank or other nominee holding your shares and follow their instructions to change your vote or revoke your proxy.

Is there a list of stockholders entitled to vote at the Annual Meeting?

The names of stockholders of record entitled to vote at the Annual Meeting will be available for ten days prior to the meeting for any purpose germane to the meeting, between the hours of 9:00 a.m. and 4:30 p.m. Pacific Time, at our corporate headquarters at 859 Ward Drive, Goleta, CA 93111.

What is the effect of giving a proxy?

Proxies are solicited by and on behalf of our Board. The persons named in the proxy have been designated as proxy holders by our Board. When a proxy is properly dated, executed and returned, the shares represented by the proxy will be voted at the Annual Meeting in accordance with the instructions of the stockholder. If no specific instructions are given, however, the shares will be voted in accordance with the recommendations of our Board. If any matters not described in this proxy statement are properly presented at the Annual Meeting, the proxy holders will use their own judgment to determine how to vote your shares. If the Annual Meeting is postponed or adjourned, the proxy holders can vote your shares on the new meeting date, unless you have properly revoked your proxy, as described above.

What if I do not specify how my shares are to be voted?

Stockholder of Record: Shares Registered in Your Name. If you are a stockholder of record and you submit a proxy but you do not provide voting instructions, your shares will be voted:

FOR the election of each of the two directors nominated by our Board and named in this proxy statement as Class I directors to serve for a three-year term (Proposal No. 1);

FOR the ratification of the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024 (Proposal No. 2);

FOR the approval, on an advisory and non-binding basis, of executive compensation for our fiscal year ended December 31, 2023 as described in this proxy statement (Proposal No. 3); and

FOR the approval of the 2023 Amended and Restated Equity Incentive Plan (Proposal No. 4).

In the discretion of the named proxy holders regarding any other matters properly presented for a vote at the Annual Meeting.

Beneficial Owners: Shares Registered in the Name of a Broker, Bank or Other Nominee. If you are a beneficial owner and you do not provide your broker, bank or other nominee that holds your shares with voting instructions, then your broker, bank or other nominee will determine if it has discretion to vote on each matter. Brokers do not have discretion to vote on non-routine matters. Proposal No. 1 (election of directors), Proposal No. 3 (advisory vote to approve Named Executive Officer (“NEO”) compensation), and Proposal No. 4 (approval of the Amended and Restated Inogen, Inc. 2023 Equity Incentive Plan)] are non-routine matters, while Proposal No. 2 (ratification of appointment of independent registered public accounting firm) is a routine matter. As a result, if you do not provide voting instructions to your broker, bank or other nominee, then your broker, bank or other nominee may not vote your shares with respect to Proposal No. 1, Proposal No. 3, or Proposal No. 4, which would result in a “broker non-vote” on each such proposal, but may, in its discretion, vote your shares with respect to Proposal No. 2. For additional information regarding broker non-votes, see “What are the effects of abstentions and broker non-votes?” below.

What is a quorum?

A quorum is the minimum number of shares required to be present at the Annual Meeting for the meeting to be properly held under our amended and restated bylaws and Delaware law. The holders of a majority of the common stock issued and outstanding and entitled to vote, present virtually or represented by proxy, constitutes a quorum for the transaction of business at the Annual Meeting. As noted above, as of the Record Date, there were a total of 23,546,871 shares of common stock outstanding, which means that 11,773,437 shares of common stock must be represented virtually or by proxy at the Annual Meeting to have a quorum. If there is no quorum, (i) the chairperson of the Annual Meeting or (ii) the stockholders entitled to vote at the Annual Meeting, present virtually in person or represented by proxy, may adjourn the meeting to a later date. Additionally, pursuant to the Company’s bylaws, the chairperson of the Annual Meeting has the power to adjourn the meeting to another place, if any, date or time, whether or not a quorum is present and without a vote of stockholders.

What are the effects of abstentions and broker non-votes?

An abstention represents a stockholder’s affirmative choice to decline to vote on a proposal. If a stockholder indicates on its proxy card that it wishes to abstain from voting its shares, or if a broker, bank or other nominee holding its customers’ shares of record causes abstentions to be recorded for shares, these shares will be considered present and entitled to vote at the Annual Meeting. As a result, abstentions will be counted for purposes of determining the presence or absence of a quorum and will also count as votes against a proposal in cases where approval of the proposal requires the affirmative vote of a majority of the shares present virtually in person or represented by proxy and entitled to vote at the Annual Meeting (e.g., Proposal No. 2, Proposal No. 3, or Proposal No. 4). However, because the outcome of Proposal No. 1 (election of directors) will be determined by a plurality vote, abstentions will have no impact on the outcome of such proposals as long as a quorum exists.

A broker non-vote occurs when a broker, bank or other nominee holding shares for a beneficial owner does not vote on a particular proposal because the broker, bank or other nominee does not have discretionary voting power with respect to such proposal and has not received voting instructions from the beneficial owner of the shares. Broker non-votes will be counted for purposes of calculating whether a quorum is present at the Annual Meeting but will not be counted for purposes of determining the number of votes cast. Therefore, a broker non-vote will make a quorum more readily attainable but will not otherwise affect the outcome of the vote on any proposal.

How many votes are needed for approval of each proposal?

How may my brokerage firm or other intermediary vote my shares if I fail to provide timely directions?

Brokerage firms and other intermediaries holding shares of common stock in street name for customers are generally required to vote such shares in the manner directed by their customers. In the absence of timely directions, your broker will have discretion to vote your shares on our sole “routine” matter — the proposal to ratify the appointment of Deloitte & Touche LLP. Absent direction from you, your broker will not have discretion to vote on the election of directors, the advisory vote regarding NEO compensation, or the approval of the Inogen, Inc. Amended and Restated 2023 Equity Incentive Plan.

Why did I receive a Notice of Internet Availability of Proxy Materials instead of a full set of proxy materials?

In accordance with the rules of the Securities and Exchange Commission (“SEC”), we have elected to furnish our proxy materials, including this proxy statement and our Annual Report, primarily via the Internet. The Notice containing instructions on how to access our proxy materials is first being mailed on or about April 18, 2024 to all stockholders entitled to vote at the Annual Meeting. Stockholders may request to receive all future proxy materials in printed form by mail or electronically by e-mail by following the instructions contained in the Notice. We encourage stockholders to take advantage of the availability of our proxy materials on the Internet to help reduce the environmental impact of our annual meetings of stockholders.

How are proxies solicited for the Annual Meeting and who is paying for such solicitation?

Our Board is soliciting proxies for use at the Annual Meeting by means of the proxy materials. We will pay the entire cost of preparing, assembling, printing, mailing, and distributing these proxy materials and soliciting votes. In addition to the mailing of these proxy materials, the solicitation of proxies or votes may be made in person, by telephone, or by electronic communication by our directors, officers, and employees, who will not receive any additional compensation for such solicitation activities. We may also reimburse brokerage firms, banks, trustees, and other nominees for the cost of forwarding proxy materials to beneficial owners. We have hired Alliance Advisors, LLC (“Alliance”) to help us solicit proxies. We expect to pay Alliance a base fee of $33,000 plus reimbursement of reasonable out-of-pocket expenses. Proxy solicitations will be made primarily through the mail, but may be supplemented by telephone, facsimile, Internet, or personal solicitation by Alliance.

If you choose to access the proxy materials and/or vote over the Internet, you are responsible for Internet access charges you may incur. If you choose to vote by telephone, you are responsible for telephone charges you may incur.

What does it mean if I received more than one Notice?

If you receive more than one Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on each Notice to ensure that all of your shares are voted.

Will members of the Board attend the Annual Meeting?

We encourage, but do not require, the members of our Board to attend the virtual Annual Meeting.

Is my vote confidential?

Proxy instructions, ballots and voting tabulations that identify individual stockholders are handled in a manner that protects your voting privacy. Your vote will not be disclosed either within Inogen or to third parties, except as necessary to meet applicable legal requirements, to allow for the tabulation of votes and certification of the vote, or to facilitate a successful proxy solicitation.

I share an address with another stockholder, and we received only one paper copy of the proxy materials. How may I obtain an additional copy of the proxy materials?

We have adopted an SEC-approved procedure called “householding,” under which we can deliver a single copy of the Notice and, if applicable, the proxy materials to multiple stockholders who share the same address unless we received contrary instructions from one or more of the stockholders. This procedure reduces our printing and mailing costs. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written or oral request, we will promptly deliver a separate copy of the Notice and, if applicable, the proxy materials to any stockholder at a shared address to which we delivered a single copy of any of these documents. To receive a separate copy, or, if you are receiving multiple copies, to request that we only send a single copy of next year’s Notice and, if applicable, proxy materials, you may contact us as follows:

Inogen, Inc.

Attention: Corporate Secretary

859 Ward Drive

Goleta, CA 93111

(805) 562-0500

Stockholders who hold shares in street name may contact their brokerage firm, bank, broker-dealer or other nominee to request information about householding.

How can I find out the results of the voting at the Annual Meeting?

Preliminary voting results will be announced at the Annual Meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the Annual Meeting. If final voting results are not available to us at that time, we intend to file a Form 8-K to publish preliminary results and, within four business days after the final results are known to us, file an amendment to the Form 8-K to publish the final results.

What is the deadline to propose actions for consideration at next year’s Annual Meeting of Stockholders or to nominate individuals to serve as directors?

For information regarding stockholder proposals and director nominations, please see the section titled “Proposals of Stockholders for 2025 Annual Meeting."

Director Independence

Our common stock is listed on the NASDAQ Global Select Market. Under the rules of the NASDAQ Global Select Market, independent directors must comprise a majority of a listed company’s Board of Directors. In addition, the rules of the NASDAQ Global Select Market require that, subject to specified exceptions, each member of a listed company’s Audit Committee, Compensation Committee, and Nominating and Governance Committee be independent. Under the rules of the NASDAQ Global Select Market, a director will only qualify as an “independent director” if, in the opinion of that company’s Board of Directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Our Board has undertaken a review of its composition, the composition of its committees and the independence of each of our directors and considered whether any director has a material relationship with us that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our Board has determined that none of Ms. Mora, Ms. Rider, Mr. Boehnlein, Mr. King, Ms. Ladone, and Mr. West, representing six of our seven directors, has a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the rules of the NASDAQ Global Select Market. Our Board also determined that Mr. Boehnlein (Chairperson), Mr. King and Ms. Ladone, who comprise our Audit Committee; Ms. Ladone (Chairperson), Ms. Rider and Ms. Mora, who comprise our Compensation Committee; Ms. Rider (Chairperson), Mr. West and Ms. Mora, who comprise our Nominating and Governance Committee, satisfy the independence standards for those committees established by applicable SEC, rules and the listing standards of the NASDAQ Global Select Market.

In making this determination, our Board considered the relationships that each non-employee director has with us and all other facts and circumstances our Board deemed relevant in determining independence, including the beneficial ownership of our capital stock by each non-employee director.

Board Leadership Structure

Our corporate governance principles require that the positions of chairperson of the Board and Chief Executive Officer must be held by separate persons and that the chairperson of our Board must be independent, as determined in accordance with the rules of the NASDAQ Global Select Market. Ms. Mora currently serves as the chairperson of our Board. Our Board believes the current board leadership structure provides effective independent oversight of management while allowing our Board and management to benefit from Ms. Mora’s leadership and years of experience in managing large and complex organizations and that Ms. Mora is best positioned to identify strategic priorities, lead critical discussion and execute our strategy and business plans. Ms. Mora possesses detailed in-depth knowledge of the issues, opportunities, and challenges facing us. Independent directors and management sometimes have different perspectives and roles in strategy development. Our Board believes that Ms. Mora’s role enables strong leadership with a focus on diversity and inclusion, creates clear accountability, facilitates information flow between management and our Board, and enhances our ability to communicate our message and strategy clearly and consistently to stockholders.

Board Diversity

Inogen embraces our Board’s diversity of background, experience, culture, and other characteristics that make the Board unique. Diversity at the top sets the expectation for inclusion throughout the organization. As a result, we are disclosing specific diversity-related metrics, including self-identified sex, race, and sexual orientation. The Equal Employment Opportunity Commission (“EEOC”) defines an “underrepresented minority” as an individual who self-identifies in one or more of the following groups: Black or African American, Hispanic or Latinx, Asian, Native American or Alaska Native, Native Hawaiian or Pacific Islander or Two or More Races or Ethnicities. The EEOC defines a “LGBTQ+” as an individual who self-identifies in one or more of the following groups: lesbian, gay, bisexual, transgender, and queer or questioning in regard to their sexual orientation. Four of the seven board directors self-identified with one or more diversity characteristic. The following table sets forth certain self-identified diversity information for our Board:

Board Diversity Matrix (As of April 8, 2024)

Board Meetings and Committees

During 2023, our Board held seven meetings (including regularly scheduled and special meetings), and each of our current directors attended at least 75% of the aggregate of (i) the total number of meetings of our Board during the periods that he or she served on the Board and (ii) the total number of meetings held by all committees of our Board on which he or she served during the periods that he or she served on such committee.

It is the policy of our Board to regularly have separate meeting times for independent directors without management. Although we do not have a formal policy regarding attendance by members of our Board at Annual Meetings of Stockholders, we encourage, but do not require, our directors to attend. All seven members of our Board at the time of the Annual Meeting attended our 2023 Annual Meeting of Stockholders.

We have established an Audit Committee, a Compensation Committee, a Nominating and Governance Committee, and a Compliance Committee.

We believe that the composition of these committees meets the criteria for independence under, and the functioning of these committees complies with the requirements of, the Sarbanes-Oxley Act of 2002, the rules of the NASDAQ Global Select Market, and SEC rules and regulations. We intend to comply with the requirements of the NASDAQ Global Select Market with respect to committee composition of independent directors. Each committee has the composition and responsibilities described below.

Audit Committee

The members of our Audit Committee are Mr. Boehnlein (Chairperson), Ms. Ladone and Mr. King, each of whom is a non-employee member of our Board.

Our Audit Committee oversees our corporate accounting and financial reporting process and assists our Board in monitoring our financial systems. Our Audit Committee also:

Our Audit Committee operates under a written charter that satisfies the applicable rules and regulations of the SEC and the listing requirements of the NASDAQ Global Select Market.

Compensation Committee

The current members of our Compensation Committee are Ms. Ladone (Chairperson), Ms. Rider and Ms. Mora. Ms. Ladone was appointed as Chairperson and Ms. Mora was appointed to the Compensation Committee in March 2024. Prior to the appointment of Ms. Ladone and Ms. Mora to the Compensation Committee in March 2024, the members of our Compensation Committee were Mr. King, Ms. Rider, and Ms. Ladone. The composition of our Compensation Committee meets the requirements for independence under current NASDAQ Global Select Market listing standards and SEC rules and regulations. Each member of the Compensation Committee is also a non-employee director, as defined pursuant to Rule 16b-3 promulgated under the Exchange Act. Our Compensation Committee oversees our compensation policies, plans and benefits programs. Our Compensation Committee also:

Our Compensation Committee operates under a written charter that satisfies the listing standards of NASDAQ Global Select Market. A copy of the charter of our Compensation Committee is available on our website at https://investor.inogen.com/corporate-governance/governance-documents. During 2023, our Compensation Committee held five meetings.

The Compensation Committee regularly reviews the services provided by its outside consultants and believes that Pearl Meyer & Partners, LLC (“Pearl Meyer”) is independent in providing executive compensation consulting services. The Compensation Committee continues to monitor the independence of its compensation consultant on a periodic basis.

Nominating and Governance Committee

The current members of our Nominating and Governance Committee are Ms. Rider (Chairperson), Mr. West and Ms. Mora. Mr. West was appointed to the Nominating and Governance Committee in April 2023. Ms. Kristin Miranda was appointed to the Nominating and Governance Committee in January 2022 and served on the committee until her resignation from the Board in March 2023. The composition of our Nominating and Governance Committee meets the requirements for independence under current NASDAQ Global Select Market listing standards and SEC rules and regulations. Our Nominating and Governance Committee oversees our plans and benefits programs. Our Nominating and Governance Committee also:

Our Nominating and Governance Committee operates under a written charter that satisfies the listing standards of the NASDAQ Global Select Market. A copy of the charter of our Nominating and Governance Committee is available on our website at https://investor.inogen.com/corporate-governance/governance-documents. During 2023, our Nominating and Governance Committee held four meetings.

Compliance Committee

The current members of our Compliance Committee are Mr. King (Chairperson), Mr. West and Mr. Boehnlein. Mr. West was appointed to the Compliance Committee in connection with his appointment to the Board in April 2023. Mr. King was appointed to the Compliance Committee in March 2024. Former director Kristen Miranda served on the Compliance Committee until her resignation from the Board in March 2023. Our Compliance Committee oversees our compliance with healthcare, legal and regulatory requirements. Our Compliance Committee also:

Our Compliance Committee operates under a written charter that satisfies the listing standards of the NASDAQ Global Select Market. During 2023, our Compliance Committee held three meetings.

Compensation Committee Interlocks

None of the members of our Compensation Committee (which includes Ms. Ladone, Ms. Rider, and Ms. Mora) and none of the members of our Compensation Committee that served during the past year (which included Mr. King and former director Kristen Miranda) are or have at any time during the past year been an officer or employee of our Company. None of our executive officers currently serves, or in the past year has served, as a member of the Board of Directors or Compensation Committee (or other board committee performing equivalent functions) of any entity that has one or more of its executive officers serving on our Board or our current Compensation Committee.

Identifying and Evaluating Nominees for Director

The Nominating and Governance Committee will use the following procedures to identify and evaluate any individual recommended or offered for nomination to the Board:

– the current size and composition of the Board and the needs of the Board and the respective committees of the Board;

– such factors as character, integrity, judgment, diversity of experience, independence, area of expertise, corporate experience, length of service, potential conflicts of interest, other commitments and the like. The Nominating and Governance Committee evaluates these factors, among others, and does not assign any particular weighting or priority to any of these factors; and

– other factors that the Nominating and Governance Committee deems appropriate.

The Nominating and Governance Committee also focuses on issues of diversity, such as diversity of gender, race and national origin, education, professional experience and differences in viewpoints and skills. Inogen does not have a formal policy with respect to diversity on the Board; however, our Board and the Nominating and Governance Committee believe that it is essential that members of our Board represent diverse viewpoints.

The Nominating and Governance Committee requires the following minimum qualifications to be satisfied by any nominee for a position on the Board:

If the Nominating and Governance Committee determines that an additional or replacement director is required, the Nominating and Governance Committee may take such measures that it considers appropriate in connection with its evaluation of a director candidate, including candidate interviews, inquiry of the person or persons making the recommendation or nomination, engagement of an outside search firm to gather additional information, or reliance on the knowledge of the members of the Nominating and Governance Committee, the Board or management.

The Nominating and Governance Committee may propose to the Board a candidate recommended or offered for nomination by a stockholder as a nominee for election to the Board.

Stockholder Recommendations for Nominations to the Board

It is the policy of the Nominating and Governance Committee of the Board to consider recommendations for candidates to the Board from stockholders holding no less than one percent (1%) of the outstanding shares of the Company’s common stock continuously for at least twelve (12) months prior to the date of the submission of the recommendation or nomination.

A stockholder that wants to recommend a candidate for election to the Board should direct the recommendation in writing by letter to the Company, attention of the Corporate Secretary, at 859 Ward Drive, Goleta, CA 93111. The recommendation must include the candidate’s name, home and business contact information, detailed biographical data, relevant qualifications, a signed letter from the candidate confirming willingness to serve, information regarding any relationships between the candidate and the Company and evidence of the recommending stockholder’s ownership of Company stock. Such recommendations must also include a statement from the recommending stockholder in support of the candidate, particularly within the context of the criteria for Board membership, including issues of character, integrity, judgment, diversity of experience, independence, area of expertise, corporate experience, length of service, potential conflicts of interest, other commitments and the like and personal references.

A stockholder that instead desires to nominate a person directly for election to the Board at an Annual Meeting of the Stockholders must meet the deadlines and other requirements set forth in the Company’s amended and restated bylaws and the rules and regulations of the Securities and Exchange Commission, including Rule 14a-19 under the Exchange Act. For information regarding stockholder proposals and director nominations, please see the section titled “Proposals of Stockholders for 2025 Annual Meeting".

Communications with the Board

The Board believes that management speaks for the Company. Individual Board members may, from time to time, communicate with various constituencies that are involved with the Company, but it is expected that Board members would do this with knowledge of management and, in most instances, only at the request of management.

In cases where stockholders and other interested parties wish to communicate directly with our non-management directors, messages can be sent to our Corporate Secretary, at Inogen, Inc., 859 Ward Drive, Goleta, California 93111, Attn: Corporate Secretary. Our Corporate Secretary monitors these communications and will provide a summary of all received messages to the Board at each regularly scheduled meeting of the Board. Our Board generally meets on a quarterly basis. Where the nature of a communication warrants, our Corporate Secretary may determine, in his or her judgment, to obtain the more immediate attention of the appropriate committee of the Board or non-management director, of independent advisors or of Company management, as our Corporate Secretary considers appropriate.

Our Corporate Secretary may decide in the exercise of his or her judgment whether a response to any stockholder or interested party communication is necessary.

This procedure for stockholder and other interested party communications with the non-management directors is administered by the Company’s Nominating and Governance Committee. This procedure does not apply to (a) communications to non-management directors from officers or directors of the Company who are stockholders, (b) stockholder proposals submitted pursuant to Rule 14a-8 under the Securities and Exchange Act of 1934, as amended, or (c) communications to the Audit Committee pursuant to the Complaint Procedures for Accounting and Auditing Matters.

Please refer to the full text of our advance notice bylaw provisions for additional information and requirements. A copy of our bylaws has been filed with our Annual Report on Form 10-K for the year ended December 31, 2023 and may be obtained by writing to our Corporate Secretary at the address listed above.

Corporate Governance Principles and Code of Ethics and Conduct

Our Board has adopted Corporate Governance Principles. These principles address items such as the qualifications and responsibilities of our directors and director candidates and corporate governance policies and standards applicable to us in general. It is our policy that the positions of Chairperson and CEO must be held by separate persons and the Chairperson must be independent as defined in the applicable NASDAQ and SEC rules. In addition, our Board has adopted a Code of Ethics and Conduct that applies to all of our employees, officers and directors, including our Chief Executive Officer, Chief Financial Officer, and other executive and senior financial officers. The full text of our Corporate Governance Principles and our Code of Ethics and Conduct is posted on our website at https://investor.inogen.com/corporate-governance/governance-documents. We intend to post any amendments to our Code of Ethics and Conduct, and any waivers of our Code of Ethics and Conduct for directors and executive officers, on the same website.

Risk Management

Risk is inherent with every business, and we face a number of risks, including strategic, financial, business and operational, legal and compliance, and reputational. We have designed and implemented processes to manage risk in our operations. Management is responsible for the day-to-day management of risks the Company faces, while our Board, as a whole and assisted by its committees, has responsibility for the oversight of risk management. In its risk oversight role, our Board has the responsibility to satisfy itself that the risk management processes designed and implemented by management are appropriate and functioning as designed.

Our Board believes that open communication between management and our Board is essential for effective risk management and oversight. Our Board meets with our Chief Executive Officer and other members of the senior management team at quarterly meetings of our Board as well as at such other times as they deem appropriate, where, among other topics, they discuss strategy and risks facing the Company.

While our Board is ultimately responsible for risk oversight, our Board committees assist our Board in fulfilling its oversight responsibilities in certain areas of risk. Our Audit Committee assists our Board in fulfilling its oversight responsibilities with respect to risk management in the areas of internal control over financial reporting, disclosure controls and procedures, cybersecurity, and legal and ethical, compliance, and discusses with management and the independent auditor guidelines and policies with respect to risk assessment and risk management. Our Audit Committee also reviews our major financial risk exposures, and the steps management has taken to monitor and control these exposures. In addition, our Audit Committee monitors certain key risks on a regular basis throughout the fiscal year, such as risk associated with internal control over financial reporting and liquidity risk. Our Nominating and Governance Committee assists our Board in fulfilling its oversight responsibilities with respect to the management of risk associated with Board organization, membership and structure, ESG reporting, and corporate governance. Our Compensation Committee also oversees risks related to our compensation policies to ensure that our compensation programs do not encourage unnecessary risk-taking. Our Compliance Committee oversees regulatory compliance areas. Finally, our full Board reviews strategic and operational risk in the context of reports from the management team, receives reports on all significant committee activities at each regular meeting, and evaluates the risks inherent in significant transactions.

Director Compensation

In October 2019, after reviewing data regarding practices at comparable companies and in consultation with our independent compensation consulting firm, Pearl Meyer, our Board, upon recommendation of the Compensation, Nominating and Governance Committee, determined it was necessary to implement changes to our non-employee director compensation levels at the time. In making this determination, the Board and the Compensation, Nominating and Governance Committee considered the midpoint range of our compensation peer group (as described in the “Compensation Discussion and Analysis” section below) as a general guideline for the appropriate level of cash and equity compensation but did not attempt to benchmark cash or equity compensation to any specific percentile. In October 2023, our Board, upon recommendation of the Compensation Committee, in consultation with Pearl Meyer, reviewed our non-employee director compensation program and determined that no changes were necessary.

In September 2020, our Board restructured our non-employee director compensation program to align with the newly separated Compensation Committee and Nominating and Governance Committee, and in July 2021, our Board restructured our non-employee director compensation program to include compensation for service on the Compliance Committee (without making any changes to the compensation for service on the Board or any other committees). In each case, our Board reviewed data provided by Pearl Meyer in setting compensation for such committees.

Also in October 2019, our Board, upon recommendation of the Compensation, Nominating and Governance Committee, adopted Equity Ownership Guidelines, applicable to our non-employee directors who receive compensation from us, executive officers, and other senior level employees. A more detailed description of these guidelines is provided in the “Equity Ownership Guidelines” section of this proxy statement below. In October 2021, our Board, upon recommendation of the Compensation Committee, in consultation with Pearl Meyer, reviewed our “Equity Ownership Guidelines” for non-employee directors and determined that no changes were necessary.

Cash Compensation. All non-employee directors are entitled to receive the following cash compensation for their services, effective October 1, 2020 (except in the case of compensation for service as Chairperson of the Compliance Committee or as a member of the Compliance Committee, in which case such compensation was effective July 28, 2021):

All cash payments to non-employee directors are paid quarterly in arrears on a pro-rata basis.

Equity Compensation.

Initial Awards: Each non-employee director who first joins us will be granted an initial award of restricted stock units (“RSUs”) covering a number of shares equal to the product of (i) the number of RSUs subject to the Annual Award (as defined below) provided to non-employee directors at the last annual meeting of stockholders preceding the date in which such person first becomes a non-employee director (the “Start Date”) multiplied by (ii) a fraction (A) the numerator of which is (x) 12 minus (y) the number of fully completed months between the date of the last annual meeting and the start date and (B) the denominator of which is 12, rounded to the nearest whole share. Each such initial award will vest on the same date as the other Annual Awards that are outstanding as of the grant date, subject to the non-employee director continuing to be a service provider through the applicable vesting date.

Annual Awards: On the date of each annual meeting of stockholders, each non-employee director will automatically be granted an award of RSUs covering a number of shares having a grant date fair value of $180,000, rounded down to the nearest whole share (the “Annual Award”). The Annual Award will vest on the earlier of (i) the one-year anniversary of the date the Annual Award is granted or (ii) the day prior to the date of the Annual Meeting following the date the Annual Award is granted, in each case, subject to the non-employee director continuing to be a service provider through the applicable vesting date.

Elections to Receive RSUs in Lieu of Cash Compensation: Each non-employee director who serves as Chairperson of our Board may elect to convert all or a portion of his or her cash compensation for service as Chairperson of our Board into an award of RSUs covering a number of shares having a grant date fair value equal to the aggregate amount of cash compensation for which the non-employee director submitted an award election, rounded down to the nearest whole share. Such award will be granted on the date of the annual meeting of stockholders and will vest quarterly in equal amounts, subject to the non-employee director continuing to be a service provider through each applicable vesting date.

All awards granted to non-employee directors of our Board are subject to 100% vesting acceleration in connection with a “change in control” pursuant to our 2023 Equity Incentive Plan (the “2023 Plan”). Effective July 27, 2023, the non-employee director compensation program was amended to reflect the capitalized terms used in the Company’s 2023 Plan, as amended from time to time, or if such plan no longer is in use at the time of the grant of an equity award, the meaning given such term or similar term in the equity plan then in place under which the equity award is granted (in each case, the “Plan”).

The table below shows compensation earned by our non-employee directors during 2023. Directors who are also our employees receive no additional compensation for their service as a director while they are also employees. During the year ended December 31, 2023, Mr. Smith, served in the role of President and Chief Executive Officer and therefore is treated as a NEO. In addition, former director Nabil Shabshab served in the role of President and Chief Executive Officer for a portion of the year and therefore is also treated as a NEO. The following table excludes Mr. Smith and Mr. Shabshab as their respective compensation is set forth in the “2023 Summary Compensation Table” below.

2023 Director Compensation Table

See “Executive Compensation” for information about the compensation of directors who also were NEOs during 2023.

Equity Ownership Guidelines

In addition, we maintain equity ownership guidelines to further align interests of directors and executives with those of our stockholders. The guideline level for non-employee directors is 3x the annual cash retainer for Board service. A more detailed description of these guidelines is provided in the “Equity Ownership Guidelines” section of this proxy statement below. While we are still within the transition period for compliance under the guidelines, as of December 31, 2023, the respective ownership levels of all of our non-employee directors did not meet the current guidelines with the exception of Ms. Rider who joined the Board in 2019.

PROPOSAL NO. 1

ELECTION OF DIRECTORS

Our Board is currently comprised of seven members. In accordance with our certificate of incorporation, our Board is divided into three classes with staggered three-year terms. At the Annual Meeting, two Class I directors will be elected for a three-year term to succeed the same class whose term is then expiring.

Each director’s term continues until the election and qualification of such director’s successor, or such director’s earlier death, resignation, or removal. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of our directors. This classification of our Board may have the effect of delaying or preventing changes in control of our Company.

Nominees

Our Nominating and Governance Committee has recommended, and our Board has approved, Ms. Mora and Ms. Rider as nominees for election as Class I directors at the Annual Meeting. If elected, each of Ms. Mora and Ms. Rider will serve as Class I directors until the 2027 Annual Meeting of Stockholders or until their successors are duly elected and qualified. Each of the nominees is currently a director of our Company. For information concerning the nominees, please see the section titled “Board of Directors and Corporate Governance.”

If you are a stockholder of record and you sign your proxy card or vote over the Internet or by telephone but do not give instructions with respect to the voting of directors, your shares will be voted FOR the election of Ms. Mora and Ms. Rider. We expect that Ms. Mora and Ms. Rider will accept such nomination. However, in the event that a director nominee is unable or declines to serve as a director at the time of the Annual Meeting, the proxies will be voted for any nominee who shall be designated by our Board to fill such vacancy. If you are a beneficial owner of shares of our common stock and you do not give voting instructions to your broker, bank or other nominee, then your broker, bank or other nominee will leave your shares unvoted on this matter.

Vote Required

The election of Class I directors requires a plurality of the shares of common stock present virtually in person or represented by proxy at the Annual Meeting and entitled to vote thereon to be approved. Broker non-votes will have no effect on this proposal.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” the election of each of the TWO directors nominated by our board of directors and named in this proxy statement as Class I directors to serve for a three-year term.

PROPOSAL NO. 2

RATIFICATION OF APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Our Audit Committee has appointed Deloitte & Touche LLP to audit the financial statements of our Company for the fiscal year ending December 31, 2024 and recommends that stockholders vote in favor of the ratification of such appointment. During the year ended December 31, 2023, Deloitte & Touche LLP served as our independent registered public accounting firm.

At the Annual Meeting, stockholders are being asked to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024. Stockholder ratification of the appointment of Deloitte & Touche LLP is not required by our amended and restated bylaws or other applicable legal requirements. However, our Board is submitting the appointment of Deloitte & Touche LLP to our stockholders for ratification as a matter of good corporate governance. In the event that this appointment is not ratified by the affirmative vote of a majority of the shares of common stock present virtually in person or represented by proxy at the Annual Meeting and entitled to vote thereon, such appointment will be reconsidered by our Audit Committee. Even if the appointment is ratified, our Audit Committee, in its sole discretion, may appoint another independent registered public accounting firm at any time during our fiscal year ending December 31, 2024 if our Audit Committee believes that such a change would be in the best interests of Inogen and its stockholders. A representative of Deloitte & Touche LLP is expected to be present virtually at the Annual Meeting, will have an opportunity to make a statement if he or she wishes to do so, and is expected to be available to respond to appropriate questions from stockholders.

Fees Paid to the Independent Registered Public Accounting Firm

The following table presents fees for professional audit services and other services rendered to us by Deloitte & Touche LLP for our fiscal years ended December 31, 2023 and 2022, respectively.

Auditor Independence

In 2023, there were no other professional services provided by Deloitte & Touche LLP that would have required our Audit Committee to consider their compatibility with maintaining the independence of Deloitte & Touche LLP.

Audit Committee Policy on Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm

Our Audit Committee has established a policy governing our use of the services of our independent registered public accounting firm. Under the policy, our Audit Committee is required to pre-approve all audit and permissible non‑audit services performed by our independent registered public accounting firm in order to ensure that the provision of such services does not impair such accounting firm’s independence. All fees paid to Deloitte & Touche LLP for our fiscal years ended December 31, 2023 and 2022 were pre-approved by our Audit Committee.

Vote Required

The ratification of the appointment of Deloitte & Touche LLP requires the affirmative vote of a majority of the shares of our common stock present virtually in person or represented by proxy at the Annual Meeting and entitled to vote thereon. Abstentions will have the effect of a vote AGAINST the proposal.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE

RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP as our independent registered public accounting firm for our fiscal year ending December 31, 2024.

PROPOSAL NO. 3

ADVISORY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, enables stockholders to approve, on an advisory or non-binding basis, the compensation of our NEOs as disclosed pursuant to Section 14A of the Exchange Act. This proposal, commonly known as a “Say-on-Pay” proposal, gives our stockholders the opportunity to express their views on our NEOs compensation as a whole. This vote is not intended to address any specific item of compensation or any specific NEO, but rather the overall compensation of all of our NEO, and the philosophy, policies and practices described in this proxy statement.

The Say-on-Pay vote is advisory, and therefore is not binding on us, the Compensation Committee or our Board. The Say-on-Pay vote will, however, provide information to us regarding investor sentiment about our executive compensation philosophy, policies and practices, which the Compensation Committee will be able to consider when determining executive compensation for the remainder of the current fiscal year and beyond. Our Board and our Compensation Committee value the opinions of our stockholders and to the extent there is any significant vote against the NEO compensation as disclosed in this proxy statement, we will endeavor to communicate with stockholders to better understand the concerns that influenced the vote, consider our stockholders’ concerns and the Compensation, Committee will evaluate whether any actions are necessary to address those concerns.

We believe that the information provided in the “Executive Compensation” section of this proxy statement, including the information discussed in “Compensation Discussion and Analysis—Executive Compensation Philosophy and Program Design” beginning on page 42 below, particularly the continued use of performance-based awards in our equity plan, demonstrates that our executive compensation program is designed appropriately and is working to ensure management’s interests are aligned with our stockholders’ interests to support long-term value creation. Accordingly, we ask our stockholders to vote “FOR” the following resolution at the Annual Meeting:

“RESOLVED, that the stockholders approve, on an advisory basis, the compensation paid to the NEOs, as disclosed in the proxy statement for the 2024 Annual Meeting pursuant to the compensation disclosure rules of the SEC, including the compensation discussion and analysis, compensation tables and narrative discussion, and other related disclosure.”

Vote Required

Approval of NEO compensation requires the affirmative vote of a majority of the shares of our common stock present virtually or represented by proxy at the Annual Meeting and entitled to vote thereon. Abstentions will have the effect of a vote AGAINST the proposal and broker non-votes will have no effect.

As an advisory vote, this proposal is non-binding. Although the vote is non-binding, our Board and our Compensation Committee value the opinions of our stockholders and will consider the outcome of the vote when making future compensation decisions for our NEOs.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” APPROVAL, ON AN ADVISORY BASIS, OF THE NAMED EXECUTIVE OFFICER COMPENSATION AS DESCRIBED IN THIS PROXY STATEMENT.

PROPOSAL NO. 4

APPROVAL OF THE AMENDED AND RESTATED 2023 EQUITY INCENTIVE PLAN

Background and Reasons for the Approval

On April 15, 2024, the Board, upon recommendation of the Compensation Committee, approved, subject to approval by our stockholders, the Inogen, Inc. Amended and Restated 2023 Equity Incentive Plan (the “Amended and Restated Plan”), which incorporates certain amendments to the existing plan (the “2023 Plan”). The Amended and Restated Plan incorporates an amendment to increase the number of shares of the Company’s common stock available for issuance under the plan by an additional 1,200,000 shares and to remove “liberal” share counting rules for stock options, stock appreciation rights or other awards. If the Amended and Restated Plan is not approved, the 2023 Plan will continue in effect, but we will not have sufficient shares available to continue to make equity awards to eligible persons and not likely to fulfill the forecasted needs beyond the fiscal calendar year.

We have historically provided stock options, restricted stock awards, and restricted stock units as an incentive to our employees, directors and consultants to promote increased stockholder value. Our Board and management believe that stock options, restricted stock, restricted stock units, and other types of equity awards are one of the primary ways to attract and retain key personnel responsible for the continued development and growth of our business, and to motivate all employees to increase stockholder value. In addition, stock options, restricted stock, restricted stock units, and other types of equity awards are considered a competitive necessity in the biotechnology industry in which we compete.

Our Board believes that the Company must offer a competitive equity incentive program if it is to continue to successfully attract and retain the best possible candidates for positions of substantial responsibility within the Company. Our Board expects that the Amended and Restated Plan will be an important factor in attracting, retaining and rewarding high caliber employees who are essential to our success and in providing incentive to these individuals to promote the success of the Company.

The Board of Directors unanimously recommends that stockholders vote “FOR” the adoption of the Amended and Restated 2023 Equity Incentive Plan.

Summary of Proposed Amendments

The material changes made by the Amended and Restated Plan are described below. However, the descriptions are qualified in their entirety by the text of the Amended and Restated Plan, which is attached to this proxy statement as Exhibit B.

Increase in Share Reserve. The Amended and Restated Plan increases the number of shares of our Common Stock reserved for issuance under the current 2023 Plan by 1,200,000 shares.

No Liberal Share Counting. The Amended and Restated Plan prohibits us from re-using shares that are tendered or surrendered to pay the exercise cost or tax obligation for grants of stock options, stock appreciation rights or other awards, shares that have been repurchased by the company on the open market using stock option exercise proceeds, or stock-settled SARs where only the actual shares delivered with respect to the award are counted against the plan reserve.

Determination of Requested Increase in Share Reserve

To determine the size of the proposed increase in shares reserved under the Amended and Restated Plan, the Compensation Committee and Board considered the following factors: (i) shares available under the 2023 Plan (ii) potential dilutive effect of requested increase in share reserve, and (iii) our 3-year average burn rate (e.g., annual shares granted as a percentage of common shares outstanding).

We expect the increased share reserve under the Amended and Restated Plan will help us remain competitive in a challenging labor environment and allow us to better attract and retain top talent and align the interests of our employees with shareholders.

Highlights of the Amended and Restated 2023 Equity Incentive Plan

The following number of shares of our common stock will be reserved for issuance under the Amended and Restated Plan: (i) 1,600,000 shares, plus (ii) (A) any shares that, as of immediately before the termination or expiration of the 2014 Equity Incentive Plan (the "2014 Plan"), have been reserved but not issued under any 2014 Plan awards and are not subject to any awards granted under the 2014 Plan, plus (B) any shares subject to awards granted under the 2014 Plan or the Company’s 2012 Equity Incentive Plan (the “2012 Plan”) that, after the 2014 Plan is terminated or expired, expire or otherwise terminate without having been exercised or issued in full or are forfeited to or repurchased by the Company due to failure to vest, with the maximum number of shares that may be added to the Amended and Restated Plan under clause (ii) above equal to 2,950,000 shares.

The Amended and Restated Plan includes several features that are consistent with protecting the interests of our stockholders and sound corporate governance practices. These features are highlighted below and are more fully described in the summary of the Amended and Restated Plan further below in this proposal. The summary is qualified in its entirety by reference to the Amended and Restated Plan as set forth in Appendix B.

Considerations of the Board of Directors in Making its Recommendation

After the consideration and input of our Compensation Committee, our Board approved the Amended and Restated Plan and the increase in the number of shares of our common stock reserved under the Amended and Restated Plan. The number of shares reserved under the Amended and Restated Plan is proposed in order to give our Board and our Compensation Committee continued flexibility to grant stock options, restricted stock, restricted stock units, and other types of equity awards.

Our Board and management believe that granting equity awards motivates higher levels of performance, aligns the interests of employees and stockholders by giving employees the perspective of owners with equity stakes in the Company, and provides an effective means of recognizing employee contributions to our success. Our Board and management also believe that equity awards are of great value in recruiting and retaining highly qualified technical and other key personnel who are in great demand, as well as rewarding and encouraging current employees and other service providers. Finally, our Board and management believe that the ability to grant equity awards will be important to our future success by helping us to accomplish these objectives.

If our stockholders approve the Amended and Restated Plan, we currently anticipate that the shares available under the Amended and Restated Plan will be sufficient to meet our expected needs through calendar year 2025. We anticipate that we will be requesting additional shares under the Amended and Restated Plan at our 2026 annual meeting of stockholders. However, future circumstances and business needs may dictate a different result. In determining the number of shares to be reserved for issuance under the Amended and Restated Plan, our Compensation Committee and our Board also considered the following:

Summary of the Amended and Restated 2023 Equity Incentive Plan

The following is a summary of the principal features of the Amended and Restated Plan and its operation. The summary is qualified in its entirety by reference to the Amended and Restated Plan as set forth in Appendix B.

General

The purposes of the Amended and Restated Plan are to attract and retain the best available personnel for positions of substantial responsibility, to provide additional incentive to employees, directors and consultants who perform services to the Company, and to promote the success of the Company’s business. These incentives are provided through the grant of stock options, restricted stock, restricted stock units, stock appreciation rights, performance units, and performance shares.

Authorized Shares

Subject to the adjustment provisions contained in the Amended and Restated Plan, stockholders are being asked to approve the reservation of the following number of shares of our common stock for issuance under the Amended and Restated Plan: (i) 1,600,000 shares, plus (ii) (A) any shares that, as of immediately before the termination or expiration of the 2014 Plan, have been reserved but not issued under any 2014 Plan awards and are not subject to any awards granted under the 2014 Plan, plus (B) any shares subject to awards granted under the 2014 Plan or 2012 Plan that, after 2014 Plan is terminated or expired, expire or otherwise terminate without having been exercised or issued in full or are forfeited to or repurchased by the Company due to failure to vest, with the maximum number of shares that may be added to the Amended and Restated Plan under clause (ii) above equal to 2,950,000 shares. In addition, shares may become available for issuance under the Amended and Restated Plan as described in the next paragraph. The shares may be authorized, but unissued, or reacquired common stock. As of April 8, 2024, the number of shares subject to awards outstanding under the 2014 Plan was 771,296 shares (in the case of performance-based awards, based on the maximum number of shares that may be issued under such awards).

If any award granted under the Amended and Restated Plan expires or becomes unexercisable without having been exercised in full, or, with respect to restricted stock, restricted stock units, performance units or performance shares, is forfeited to or repurchased by the Company due to failure to vest, then the unpurchased or forfeited or repurchased shares subject to such award will become available for future grant or sale under the Amended and Restated Plan (unless the Amended and Restated Plan has terminated). Upon exercise of a stock appreciation right settled in shares, the gross number of shares covered by the portion of the exercised stock appreciation right (whether or not actually issued as a result of such exercise) will cease to be available under the Amended and Restated Plan. If shares issued under restricted stock, restricted stock units, performance shares or performance units are repurchased by or forfeited to the Company due to failure to vest, such shares will become available for future grant under the Amended and Restated Plan. If an award is paid out in cash rather than shares, the number of shares available for issuance under the Amended and Restated Plan will not be reduced.

Adjustments to Shares Subject to the Amended and Restated Plan

In the event of any dividend or other distribution (whether in the form of cash, shares, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, reclassification, repurchase, or exchange of shares or other securities of the Company, or other change in the corporate structure affecting our common stock occurs (other than any ordinary dividends or other ordinary distributions), the Administrator, in order to prevent diminution or enlargement of the benefits or potential benefits intended to be made available under the Amended and Restated Plan, will adjust the number and class of shares of stock that may be delivered under the Amended and Restated Plan, and/or the number, class and price of shares of stock subject to outstanding awards, and the numerical share limits in the Amended and Restated Plan.

Administration

The Amended and Restated Plan will be administered by our Board, any committee of our Board, or a committee of individuals satisfying applicable laws appointed by our Board or a duly authorized committee of our Board in accordance with the terms of the Amended and Restated Plan (the “Administrator”). In the case of transactions, including grants to certain officers and key employees of the Company, intended to qualify, as exempt under Rule 16b-3 of the Securities Exchange Act of 1934 (the “Exchange Act”), the members of the committee must qualify as “non-employee directors” under Rule 16b‑3 of the Exchange Act.

Subject to the terms of the Amended and Restated Plan, the Administrator has the authority to interpret and administer the Amended and Restated Plan, including but not limited to, the authority, in its discretion, to select the employees, consultants, and directors who will receive awards, to determine the terms and conditions of awards, to modify or amend each award (subject to the restrictions of the Amended and Restated Plan), including to accelerate vesting or waive forfeiture restrictions, to extend the post-service exercise period applicable to an award, and to interpret the provisions of the Amended and Restated Plan and outstanding awards. The Administrator may allow a participant to defer the receipt of payment of cash or delivery of shares that otherwise would be due to such participant. The Administrator may make rules and regulations relating to sub-plans established for the purpose of facilitating compliance with applicable non-U.S. laws, easing administration of the Amended and Restated Plan, or qualifying for favorable tax treatment under applicable non-U.S. laws and may make all other determinations deemed necessary or advisable for administering the Amended and Restated Plan. The Administrator may temporarily suspend the exercisability of an award if the Administrator deems such suspension to be necessary or appropriate for administrative purposes or to comply with applicable laws, provided that such suspension must be lifted before the expiration of the maximum term and post-service exercisability period of an award, unless doing so would not comply with applicable laws.

Eligibility

Awards may be granted to employees, directors and consultants of the Company and employees and consultants of any parent or subsidiary corporation of the Company. Incentive stock options may be granted only to employees who, as of the time of grant, are employees of the Company or any parent or subsidiary corporation of the Company. As of March 31, 2024, approximately 864 employees, 6 non-employee directors, and 9 consultants were eligible to participate in the Amended and Restated Plan. As of the same date, the closing price of a share of our common stock as reported on the Nasdaq Global Select Market was $8.07.

Limitations

The Administrator may not institute an exchange program under which (i) outstanding awards are surrendered or cancelled in exchange for awards of the same type (which may have a higher or lower exercise price and/or different terms), awards of a different type and/or cash, (ii) which participants have the opportunity to transfer outstanding awards to a financial institution, or (iii) the exercise price of an outstanding award is reduced.

Dividends or other distributions payable with respect to shares subject to equity awards will not be paid before and unless the underlying shares vest. No dividends or other distributions will be paid with respect to shares that are subject to unexercised options or stock appreciation rights.

Except for awards granted under our non-employee director compensation program, no portion of an award granted under the Amended and Restated Plan may vest earlier than the one-year anniversary of such award’s date of grant, unless accelerated by reason of an award holder’s death or disability, provided that awards may be granted to any service provider (or awards may be modified) without regard to such minimum vesting requirements to the extent such grants (or modifications) would not result in the issuance of an aggregate of more than 5% of the shares reserved for issuance under the Amended and Restated Plan.

The Amended and Restated Plan provides, in any fiscal year, that no non-employee director may be granted equity awards (the value of which will be based on their grant date fair value determined in accordance with U.S. generally accepted accounting principles (“GAAP”)) and be provided any cash retainers or annual or meeting fees for service as a non-employee director in amounts that, in the aggregate, exceed $750,000, except that such amount will be increased to $1,000,000 in the fiscal year of his or her initial service as a non-employee director. Any equity awards or other compensation provided to an individual while he or she was an employee, or while he or she was a consultant but not a non-employee director, will not count for purposes of these limitations.

Stock Options

Each option granted under the Amended and Restated Plan will be evidenced by a written or electronic agreement between the Company and a participant specifying the number of shares subject to the option and the other terms and conditions of the option, consistent with the requirements of the Amended and Restated Plan.

The exercise price per share of each option may not be less than the fair market value of a share of our common stock on the date of grant. However, an exception may be made for any options that are granted in substitution for options held by employees of companies that the Company acquires in a manner consistent with Section 424(a) of the Code. In addition, any incentive stock option granted to an employee who, at the time of grant, owns stock representing more than 10% of the total combined voting power of all classes of stock of the Company or any parent or subsidiary corporation of the Company (a “Ten Percent Stockholder”) must have an exercise price per share equal to at least 110% of the fair market value of a share on the date of grant. The aggregate fair market value of the shares (determined on the grant date) covered by incentive stock options that first become exercisable by any participant during any calendar year also may not exceed $100,000. Generally, the fair market value of our common stock is the closing price of our stock on any established stock exchange or national market system on the applicable date.

The Amended and Restated Plan provides that the Administrator will determine the acceptable form(s) of consideration for exercising an option. An option will be deemed exercised when the Company receives the notice of exercise and full payment for the shares to be exercised, together with any applicable tax withholdings.

Options will be exercisable at such times or under such conditions as determined by the Administrator and set forth in the award agreement. The maximum term of an option will be specified in the award agreement, but an incentive stock option must have a term not exceeding 10 years (or in the case of an incentive stock option granted to a Ten Percent Stockholder, 5 years).

The Administrator will determine and specify in each award agreement, and solely in its discretion, the period of exercise applicable to each option following a service provider’s cessation of service. In the absence of such a determination by the Administrator, the participant generally will be able to exercise his or her option for (i) 3 months following his or her cessation of service for reasons other than death or disability, and (ii) 12 months following his or her cessation of service due to disability or following his or her death while holding the option. An award agreement may provide for an extension of a post-service exercise period upon a cessation of service for reasons other than death or disability if the exercise of the option following such cessation of service would result in liability under Section 16(b) of the Exchange Act or would violate the registration requirements under the Securities Act.

Restricted Stock Awards

Awards of restricted stock are rights to acquire or purchase shares, which vest in accordance with the terms and conditions established by the Administrator in its sole discretion. Each restricted stock award granted will be evidenced by a written or electronic agreement between the Company and the participant specifying the number of shares subject to the award and the other terms and conditions of the award, consistent with the requirements of the Amended and Restated Plan. Restricted stock awards may be subject to vesting conditions if and as the Administrator specifies, and the shares acquired may not be transferred by the participant until vested. The Administrator may set restrictions based upon continued employment or service, the achievement of specific performance objectives (Company-wide, departmental, divisional, business unit or individual), applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion.

Unless otherwise provided by the Administrator, a participant will forfeit any shares of restricted stock as to which the restrictions have not lapsed before the participant’s cessation of service. Unless the Administrator provides otherwise, and subject to the general rules in the Amended and Restated Plan related to dividends (described below), participants holding restricted stock will have the right to vote the underlying shares. The Administrator may, in its sole discretion, reduce or waive any restrictions and may accelerate the time at which any restrictions will lapse or be removed.

Restricted Stock Units

The Administrator may grant restricted stock units which represent a right to receive shares at a future date as set forth in the participant’s award agreement. Each restricted stock unit granted under the Amended and Restated Plan will be evidenced by a written or electronic agreement between the Company and the participant specifying the number of shares subject to the award and other terms and conditions of the award, consistent with the requirements of the Amended and Restated Plan. Restricted stock units may be settled, in the sole discretion of the Administrator, in shares, cash or a combination of cash and shares.

Restricted stock units will result in a payment to a participant only if the performance goals or other vesting criteria (if any) the Administrator may establish are achieved or the awards otherwise vest. The Administrator may set vesting criteria based upon continued employment or service, the achievement of specific performance objectives (Company-wide, departmental, divisional, business unit, or individual goals (including, but not limited to, continued employment or service)), applicable federal or state securities laws or any other basis determined by the Administrator in its discretion, which, depending on the extent to which they are met, will determine the number of restricted stock units to be paid out to participants.

After the grant of a restricted stock unit award, the Administrator, in its sole discretion, may reduce or waive any vesting criteria that must be met to receive a payout and may accelerate the time at which any restrictions will lapse or be removed. A participant will forfeit any unearned restricted stock units as of the date set forth in the award agreement. The Administrator in its sole discretion may pay earned restricted stock units in cash, shares of our common stock, or a combination of cash and shares.

Stock Appreciation Rights

A stock appreciation right gives a participant the right to receive the appreciation in the fair market value of our common stock between the date of grant of the award and the date of its exercise. Each stock appreciation right granted under the Amended and Restated Plan will be evidenced by a written or electronic agreement between the Company and the participant specifying the exercise price and the other terms and conditions of the award, consistent with the requirements of the Amended and Restated Plan.

The exercise price per share of each stock appreciation right may not be less than the fair market value of a share on the date of grant. Upon exercise of a stock appreciation right, the holder of the award will be entitled to receive an amount determined by multiplying (i) the difference between the fair market value of a share on the date of exercise over the exercise price by (ii) the number of exercised shares. The Company may pay the appreciation in cash, in shares, or in some combination of cash and shares. The term of a stock appreciation right will be set forth in the award agreement. The terms and conditions relating to the period of exercise following a cessation of service with respect to options described above also apply to stock appreciation rights.

Performance Units and Performance Shares

Performance units and performance shares may also be granted under the Amended and Restated Plan. Performance units and performance shares are awards that will result in a payment to a participant only if the performance goals or other vesting criteria (if any) the Administrator may establish are achieved or the awards otherwise vest. Each award of performance units or shares granted under the Amended and Restated Plan will be evidenced by a written or electronic agreement between the Company and the participant specifying the performance period and other terms and conditions of the award, consistent with the requirements of the Amended and Restated Plan. Earned performance units and performance shares will be paid, in the sole discretion of the Administrator, in the form of cash, shares (which will have an aggregate fair market value equal to the earned performance units or shares at the close of the applicable performance period), or in a combination of cash and shares. The Administrator may set vesting criteria based upon continued employment or service, the achievement of specific performance objectives (Company-wide, departmental, divisional, business unit or individuals goals (including, but not limited to, continued employment or service)), applicable federal or state securities laws, or any other basis determined by the Administrator in its discretion, and which, depending on the extent to which they are met, will determine the number and/or the value of performance units and performance shares to be paid out to participants.

After the grant of a performance unit or performance share, the Administrator, in its sole discretion, may reduce or waive any performance objectives or other vesting provisions for such performance units or shares. Performance units will have an initial value established by the Administrator on or before the date of grant. Each performance share will have an initial value equal to the fair market value of a share on the grant date. A participant will forfeit any performance shares or units that are unearned or unvested as of the date set forth in the award agreement.

Transferability of Awards

Unless determined otherwise by the Administrator and subject to the terms of the Amended and Restated Plan, awards granted under the Amended and Restated Plan generally are not transferable other than by will or by the laws of descent and distribution, and all rights with respect to an award granted to a participant generally will be available during a participant’s lifetime only to the participant.

Dissolution or Liquidation

In the event of the Company’s proposed dissolution or liquidation, the Administrator will notify each participant as soon as practicable before the effective date of such proposed transaction. An award will terminate immediately before consummation of such proposed action to the extent the award has not been previously exercised or vested.

Change in Control

The Amended and Restated Plan provides that, in the event of a merger of the Company with or into another corporation or entity or a “change in control” (as defined in the Amended and Restated Plan), each award will be treated as the Administrator determines without a participant’s consent, including, without limitation, that (i) awards will be assumed, or substantially equivalent awards will be substituted, by the acquiring or succeeding corporation or its affiliate with appropriate adjustments as to the number and kind of shares and prices; (ii) upon written notice to a participant, that the participant’s awards will terminate upon or immediately before the consummation of such merger or change in control; (iii) outstanding awards will vest and become exercisable, realizable or payable or restrictions applicable to an award will lapse, in whole or in part, before or upon consummation of such merger of change in control, and, to the extent the Administrator determines, terminate upon or immediately before the effectiveness of such merger or change in control; (iv) (A) the termination of an award in exchange for an amount of cash and/or property, if any, equal to the amount that would have been attained upon the exercise of such award or realization of the participant’s rights as of the date of the occurrence of the transaction (and, for the avoidance of doubt, if as of the date of the occurrence of the transaction the Administrator determines in good faith that no amount would have been attained upon the exercise of such award or realization of the participant’s rights, then such award may be terminated by the Company without payment), or (B) the replacement of such award with other rights or property selected by the Administrator in its sole discretion; or (v) any combination of the above. In taking any of the actions permitted by the Amended and Restated Plan, the Administrator will not be obligated to treat all awards, all awards held by a participant, all awards of the same type, or all portions of awards, similarly in the transaction.

If the successor corporation does not assume or substitute for an award (or portion of an award), the participant will fully vest in and have the right to exercise the participant’s outstanding options and stock appreciation rights (or portions of such awards) that are not assumed or substituted for, all restrictions on restricted stock, restricted stock units, performance shares and performance units (or portions of such awards) not assumed or substituted for will lapse, and, with respect to such awards with performance-based vesting (or portions of such awards), all performance goals or other vesting criteria will be deemed achieved at 100% of target levels and all other terms and conditions met, in each case, unless specifically provided otherwise by the Administrator or under the applicable award agreement or other written agreement authorized by the Administrator between the participant and the Company or any of its subsidiaries or parents. In addition, unless specifically provided otherwise by the Administrator or under the applicable award agreement or other written agreement authorized by the Administrator between the participant and the Company or any of its subsidiaries or parents, if an option or stock appreciation right (or portion of such award) is not assumed or substituted for, the Administrator will notify the participant in writing or electronically that the option or stock appreciation right (or its applicable portion) will be exercisable for a period of time determined by the Administrator in its sole discretion, and the option or stock appreciation right (or its applicable portion) will terminate upon the expiration of such period.

If the service of an award holder is terminated on or within the 12 months following a change in control, as a result of an involuntary termination as defined in the Amended and Restated Plan, his or her options, restricted stock units and stock appreciation rights, if any, will vest fully and become immediately exercisable, all restrictions on his or her restricted stock will lapse, and all performance goals or other vesting requirements for his or her performance shares and units will be deemed achieved at 100% of target levels, and all other terms and conditions met, unless specifically provided otherwise by the Administrator or under the applicable award agreement or other written agreement authorized by the Administrator between the participant and the Company or any of its subsidiaries or parents.

In addition, with respect to awards granted to a non-employee director while such individual was a non-employee director, in the event of a change in control, the non-employee director’s options, stock appreciation rights, restricted stock and restricted stock units, if any, will vest fully and become immediately exercisable, all restrictions on his or her restricted stock will lapse, and all performance goals or other vesting for his or her performance shares and units will be deemed achieved at 100% of target levels, and all other terms and conditions met, unless specifically provided otherwise by the Administrator or under the applicable award agreement or other written agreement authorized by the Administrator between the participant and the Company or any of its subsidiaries or parents.

Forfeiture Events

The Administrator may specify in an award agreement that the participant’s rights, payments and benefits with respect to an award will be subject to reduction, cancellation, forfeiture, recoupment, reimbursement, or reacquisition upon the occurrence of certain specified events. Awards will be subject to reduction, cancellation, forfeiture, recoupment, reimbursement, or reacquisition under any clawback policy that we are required to adopt under the listing standards of any national securities exchange or association on which our securities are listed or as is otherwise required by applicable laws. The Administrator may require a participant to forfeit, return or reimburse us all or a portion of the award and any amounts paid under the award, according to such clawback policy or in order to comply with applicable laws.

Termination or Amendment

The Amended and Restated Plan will automatically terminate 10 years from the date of its initial adoption by our Board in 2023, unless terminated at an earlier time by the Administrator. The Administrator may amend, alter, suspend or terminate the Amended and Restated Plan at any time, provided that the Company will obtain stockholder approval of any amendment to the extent approval is necessary and desirable to comply with any applicable laws. No amendment, alteration, suspension or termination will materially impair the rights of any participant unless mutually agreed otherwise between the participant and the Administrator.

Federal Tax Aspects

The following summary is intended only as a general guide to the material U.S. federal income tax consequences of participation in the Amended and Restated Plan. The summary is based on existing U.S. laws and regulations, and there can be no assurance that those laws and regulations will not change in the future. The summary does not purport to be complete and does not discuss the tax consequences upon a participant’s death, or the provisions of the income tax laws of any municipality, state or non-U.S. country in which the participant may reside. As a result, tax consequences for any particular participant may vary based on individual circumstances.

Incentive Stock Options

An optionee recognizes no taxable income for regular income tax purposes as a result of the grant or exercise of an incentive stock option qualifying under Section 422 of the Code. Optionees who neither dispose of their shares within two years following the date the option was granted nor within one year following the exercise of the option normally will recognize a capital gain or loss equal to the difference, if any, between the sale price and the purchase price of the shares. If an optionee satisfies such holding periods upon a sale of the shares, the Company will not be entitled to any deduction for federal income tax purposes. If an optionee disposes of shares within two years after the date of grant or within one year after the date of exercise (a “disqualifying disposition”), the difference between the fair market value of the shares on the exercise date and the option exercise price (not to exceed the gain realized on the sale if the disposition is a transaction with respect to which a loss, if sustained, would be recognized) will be taxed as ordinary income at the time of disposition. Any gain in excess of that amount will be a capital gain. If a loss is recognized, there will be no ordinary income, and such loss will be a capital loss. Any ordinary income recognized by the optionee upon the disqualifying disposition of the shares generally should be deductible by the Company for federal income tax purposes, except to the extent such deduction is limited by applicable provisions of the Code.

The difference between the option exercise price and the fair market value of the shares on the exercise date is treated as an adjustment in computing the optionee’s alternative minimum taxable income and may be subject to an alternative minimum tax which is paid if such tax exceeds the regular tax for the year. Special rules may apply with respect to certain subsequent sales of the shares in a disqualifying disposition, certain basis adjustments for purposes of computing the alternative minimum taxable income on a subsequent sale of the shares and certain tax credits which may arise with respect to optionees subject to the alternative minimum tax.

Nonstatutory Stock Options

Options not designated or qualifying as incentive stock options will be nonstatutory stock options having no special U.S. tax status. An optionee generally recognizes no taxable income as the result of the grant of such an option. Upon exercise of a nonstatutory stock option, the optionee normally recognizes ordinary income equal to the amount that the fair market value of the shares on such date exceeds the exercise price. If the optionee is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Upon the sale of stock acquired by the exercise of a nonstatutory stock option, any gain or loss, based on the difference between the sale price and the fair market value on the exercise date, will be taxed as capital gain or loss. No tax deduction is available to the Company with respect to the grant of a nonstatutory stock option or the sale of the stock acquired through such grant.

Stock Appreciation Rights

In general, no taxable income is reportable when a stock appreciation right is granted to a participant. Upon exercise, the participant generally will recognize ordinary income in an amount equal to the fair market value of any shares of our common stock received. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Any additional gain or loss recognized upon any later disposition of the shares would be capital gain or loss.

Restricted Stock Awards

A participant acquiring restricted stock generally will recognize ordinary income equal to the fair market value of the shares on the vesting date. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. The participant may elect, under Section 83(b) of the Code, to accelerate the ordinary income tax event to the date of acquisition by filing an election with the Internal Revenue Service no later than 30 days after the date the shares are acquired. Upon the sale of shares acquired through a restricted stock award, any gain or loss, based on the difference between the sale price and the fair market value on the date the ordinary income tax event occurs, will be taxed as capital gain or loss.

Restricted Stock Units

There generally are no immediate tax consequences of receiving an award of restricted stock units. A participant who is awarded restricted stock units generally will be required to recognize ordinary income in an amount equal to the fair market value of shares issued to such participant at the end of the applicable vesting period or, if later, the settlement date elected by the Administrator or a participant. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Any additional gain or loss recognized upon any later disposition of any shares received would be capital gain or loss.

Performance Units and Performance Shares

A participant generally will recognize no income upon the grant of a performance share or a performance unit award. Upon the settlement of such awards, participants normally will recognize ordinary income in the year of receipt in an amount equal to the cash received and the fair market value of any cash or nonrestricted shares received. If the participant is an employee, such ordinary income generally is subject to withholding of income and employment taxes. Upon the sale of any shares received, any gain or loss, based on the difference between the sale price and the fair market value on the date the ordinary income tax event occurs, will be taxed as capital gain or loss.

Section 409A

Section 409A of the Code provides certain requirements for non-qualified deferred compensation arrangements with respect to an individual’s deferral and distribution elections and permissible distribution events. Awards granted under the Amended and Restated Plan with a deferral feature will be subject to the requirements of Section 409A of the Code. If an award is subject to and fails to satisfy the requirements of Section 409A of the Code, the recipient of that award may recognize ordinary income on the amounts deferred under the award, to the extent vested, which may be before the compensation is actually or constructively received. Also, if an award that is subject to Section 409A fails to comply with Section 409A’s provisions, Section 409A imposes an additional 20% federal income tax on compensation recognized as ordinary income, as well as interest on such deferred compensation. Certain states have enacted laws similar to Section 409A which impose additional taxes, interest and penalties on non-qualified deferred compensation arrangements. The Company will also have withholding and reporting requirements with respect to such amounts.

Medicare Surtax

A participant’s annual “net investment income”, as defined in Section 1411 of the Code, may be subject to a 3.8% federal surtax (generally referred to as the “Medicare Surtax”). Net investment income may include capital gain and/or loss arising from the disposition of shares subject to a participant’s awards under the Amended and Restated Plan. Whether a participant’s net investment income will be subject to the Medicare Surtax will depend on the participant’s level of annual income and other factors.

Tax Effect for the Company

The Company generally will be entitled to a tax deduction in connection with an award under the Amended and Restated Plan in an amount equal to the ordinary income realized by a participant and at the time the participant recognizes such income (for example, the exercise of a nonstatutory stock option). Special rules limit the deductibility of compensation paid to our chief executive officer and other “covered employees” as determined under Section 162(m) of the Code and applicable guidance. Under Section 162(m), the annual compensation paid to any of these specified executives will be deductible only to the extent that it does not exceed $1,000,000.

Number of Awards Granted to Employees, Consultants, and Directors

The number of awards that an employee, director or consultant may receive under the Amended and Restated Plan is in the discretion of the Administrator and therefore cannot be determined in advance. The following table sets forth (i) the aggregate number of shares of our common stock subject to restricted stock units (in the case of performance-based restricted stock units, at target levels) granted under the 2023 Plan to our NEOs and the below-listed groups during the last fiscal year (no other types of awards were granted to such individuals during the last fiscal year), (ii) the average per share exercise price of such options, and (iii) the dollar value of such restricted stock units based on their aggregate grant date fair value determined under FASB ASC Topic 718.

(1) Reflects the aggregate grant date fair value of the equity awards computed in accordance with FASB ASC Topic 718.

Required Vote

Approval of the Amended and Restated Plan requires the affirmative vote of a majority of the shares of our common stock present virtually or represented by proxy at the Annual Meeting and entitled to vote thereon. Abstentions will have the effect of a vote AGAINST the proposal and broker non-votes will have no effect.

Summary

We believe strongly that approval of the Amended and Restated Plan is essential to our continued success and ability to compete for talent in the labor markets in which we operate. Our employees are one of our most valuable assets. Stock options and other awards such as those provided under the Amended and Restated Plan are vital to our ability to attract and retain outstanding and highly skilled individuals. Such awards also are crucial to our ability to motivate employees to achieve the Company’s goals. For the reasons stated above, the stockholders are being asked to approve the Amended and Restated Plan.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" THE AMENDED AND RESTATED 2023 EQUITY INCENTIVE PLAN.

AUDIT COMMITTEE REPORT

The information contained in the following Audit Committee Report shall not be deemed to be “soliciting material” or to be “filed” with the Securities and Exchange Commission, nor shall such information be incorporated by reference into any future filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except to the extent that Inogen, Inc., or the Company, specifically incorporates it by reference in such filing.

The primary purpose of our Audit Committee is to oversee our financial reporting process on behalf of our Board. The Audit Committee’s functions are more fully described in its charter, which is available on our website at www.inogen.com in the Corporate Overview – Governance Documents section of our Investors webpage. The Audit Committee reviews and reassesses the adequacy of its charter and the Audit Committee’s performance on an annual basis.

The Audit Committee does not itself prepare financial statements or perform audits, and its members are not auditors or certifiers of our financial statements. Management has the primary responsibility for our financial statements and reporting processes, including our systems of internal controls. Our independent registered public accounting firm is responsible for performing an independent audit of our financial statements in accordance with generally accepted auditing standards and the effectiveness of our internal control over financial reporting and issuing a report thereon.

The Audit Committee also reviews the performance of our independent registered public accounting firm, Deloitte & Touche LLP in the annual audit of our financial statements and in assignments unrelated to the audit, and reviews and approves the independent registered public accounting firm’s audit and non-audit fees.

The members of the Audit Committee are currently Glenn Boehnlein (chairperson), Kevin King and Mary Katherine Ladone. Each of the members of the Audit Committee is an independent director as currently defined in the applicable NASDAQ and Securities and Exchange Commission (“SEC”) rules. The Board has also determined that each of Mr. Boehnlein and Ms. Ladone is an “audit committee financial expert” as described in applicable rules and regulations of the SEC. The Audit Committee provides our Board such information and materials as it may deem necessary to make our Board aware of financial matters requiring the attention of our Board. The Audit Committee reviews our financial disclosures and meets privately, outside the presence of our management, with our independent registered public accounting firm. In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed the audited financial statements in our Annual Report with management, including a discussion of the quality and substance of the accounting principles and significant accounting policies, the reasonableness of significant judgments made in connection with the audited financial statements, and the clarity of disclosures in the financial statements. The Audit Committee reports on these meetings to our Board.

The Audit Committee has reviewed and discussed the Company’s audited financial statements with management and Deloitte & Touche LLP, the Company’s independent registered public accounting firm. The Audit Committee has discussed with Deloitte & Touche LLP the matters required to be discussed by Auditing Standard No. 1301, “Communications with Audit Committees” issued by the Public Company Accounting Oversight Board (“PCAOB”).

The Audit Committee has received and reviewed the written disclosures and the letter from Deloitte & Touche LLP required by the applicable requirements of the PCAOB regarding Deloitte & Touche LLP’s communications with the Audit Committee concerning independence, and has discussed with Deloitte & Touche LLP its tenure and independence.

Based on the review and discussions referred to above, the Audit Committee recommended to the Board that the Company’s Audited Financial Statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 for filing with the SEC. The Audit Committee also has selected Deloitte & Touche LLP as the independent registered public accounting firm for fiscal year 2024. The Board recommends that stockholders ratify this selection at the Annual Meeting.

Respectfully submitted by the members of the Audit Committee of the Board of Directors:

Glenn Boehnlein (Chairperson)

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

This Compensation Discussion and Analysis describes the principles underlying the material components of our executive compensation program for our executive officers, including the NEOs, in the “Summary Compensation Table.” We also provide an overview of the overall objectives of the program and the factors relevant to an analysis of these policies and decisions and how we use our executive compensation program to drive our performance.

Our NEOs for 2023 were:

2023 Management Changes

2023 was a transition year for us as we had turnover in two-thirds of the members of the management team. Our 2023 executive compensation programs and decisions reflect this. The amount and terms of the compensation provided to our new NEOs were set at levels that we believed were important to recruit these highly qualified executives to our company and retain them over the long-term. As a result, the compensation provided to our incoming NEOs in 2023 is greater in value than what we ordinarily might provide them for a typical year as they include incentives that are designed to compensate these executives for compensation opportunities that they forfeited when leaving their prior employers.

Executive Summary

We believe we are a leader in portable oxygen concentrators and that the market for our technology remains underpenetrated.

We are committed to our purpose of improving lives through respiratory care. We believe we can create long-term shareholder value by focusing on increasing patient and physician awareness of our products, expanding clinical research, growing revenue, and optimizing our business. We maintain our belief that the need and patient preference for our best-in-class portable oxygen concentrators remains strong.

2023 Business Performance and Compensation

Our 2023 results include:

Please see Appendix A attached to this proxy statement for a reconciliation of non-GAAP Adjusted EBITDA and non-GAAP Adjusted Operating Loss, in each case to net loss, as calculated in accordance with GAAP.

Based on 2023 performance and as further described below, (i) annual bonus plan payouts were made to our senior executive team for 2023 at 25% of target payout levels, (ii) none of the first tranche of the performance-based equity awards granted to the NEOs in March 2023 vested, (iii) none of the second tranche of the performance-based equity awards granted to the NEOs in March 2022 vested, and (iv) none of the third tranche of the performance-based equity awards granted to the NEOs in March 2021 vested. We believe the below-target annual cash incentive plan payout and no vesting of any performance-based equity awards during 2023 demonstrate the strong alignment between performance and compensation outcomes for our NEOs.

2023 Say-on-Pay Vote and Stockholder Engagement Efforts

Historically, stockholder say-on-pay support for our executive compensation program has been extremely strong — averaging 98% between 2018 and 2022. However, at last year’s annual meeting of stockholders held in June 2023, 71% of the votes cast on our say-on-pay proposal (excluding broker non-votes and abstentions) were cast in favor of the compensation of the NEOs on an advisory basis. In light of this result, and consistent with our commitment to listen and respond to our stockholders, we increased our stockholder outreach and engagement efforts to better understand current perspectives on our executive compensation program.

In addition to our regular cadence of stockholder outreach and engagement during 2023, we reached out directly to stockholders to discuss, amongst other topics, our compensation practices. Significant stockholders participated in meetings with us at which either members of senior management and/or independent members of the Board, including the Chairperson of the Compensation Committee, participated.

Overall, our stockholders indicated to us that they continue to be supportive of our executive compensation program design. However, a few common themes emerged from the discussions, placing our focus on strengthening the links between pay and performance. We have taken multiple steps to address the key concerns we heard, as explained in the table below.

We believe these changes create a stronger incentive structure that continues to incentivize the senior leadership team to execute on strategies that drive our business results and reflects our stockholders’ preferences. We will continue to keep an open dialogue with our stockholders to help ensure that we have a regular input on their perspectives.

2023 Executive Compensation Program

Our executive compensation program is designed to be competitive and balance our goals of attracting, motivating, rewarding, and retaining our executive officers and driving company performance. To align our executive officers’ interests with those of our stockholders, a substantial portion of each executive officer’s target annual total direct compensation opportunity is “at-risk,” meaning the amounts paid to each executive officer will vary based on our Company performance.

In general, we target total cash compensation and other executive compensation levels to be within the 50th percentile of our peer group and comparable to similarly situated executives. However, the specific competitiveness of any individual executive’s pay will be determined considering factors like the executive’s experience, skills and capabilities, contributions as a member of the executive management team, and contributions to our overall performance. The Compensation Committee also consider the sufficiency of total compensation potential and the structure of pay plans to ensure the hiring or retention of an executive when considering the competitive labor environment.

Consistent with our pay-for-performance philosophy, we took the following actions during 2023 with respect to NEO compensation.

Based on our results in revenue and Adjusted EBITDA in 2023, the financial portions of our bonus pool were unfunded at 0% of target for our NEOs under the 2023 Incentive Plan (as defined below). Individual goals for the remaining 25% were funded based on achievement between 80%-100%.

In 2023, we did not meet our thresholds for Adjusted Operating Income or revenue goals; as a result, the 2023 tranches of our NEOs' performance-based RSU awards vested at 0% of target for each of the awards granted in 2023, 2022 and 2021.

New CEO Compensation

Kevin Smith was appointed as President and CEO of the Company, effective November 10, 2023. In setting Mr. Smith’s annual compensation as well as his sign-on grants, the Compensation Committee considered factors including, but not limited to, his extensive industry experience, leadership roles requiring innovation and thought leadership, technical acumen and the compensation of CEOs at similarly situated publicly traded companies. The following is an overview of his compensation:

2023 Annual Target Direct Compensation: Mr. Smith’s regular annual target direct compensation is comprised of an annual base salary and target annual and long-term equity compensation opportunities as follows:

One-Time Sign-On Grants: In addition to offering Mr. Smith a competitive annual compensation package, the Board approved one-time new hire awards in part to make up for forgone incentives at his previous employer as follows:

The shift to the use of PSUs as an equity sign-on award is intended to drive achievement of key performance goals.

Executive Compensation Governance Highlights

We maintain sound governance standards consistent with our executive compensation policies and practices and we seek to adhere to the best practices for compensation and corporate governance purposes. The Compensation Committee and in certain cases, the independent members of our Board, evaluate our executive compensation program regularly to ensure that it supports our short-term and long-term goals given the dynamic nature of our business and the market in which we compete for executive talent as well as protect our stockholders’ interests. These policies and practices were in effect during 2023:

Compensation Governance

Executive Compensation Policies and Practices

Our compensation philosophy and related corporate governance policies and practices are complemented by several specific compensation practices designed to align our executive compensation with long-term stockholder interests, including:

Executive Compensation Philosophy and Program Design

Overview

The goals of our executive compensation program are to attract, retain, motivate and reward executive officers who contribute to our success and to incentivize these executives to achieve our short-term and long-term business objectives in order to increase long-term value and increase stockholder returns. This program combines competitive cash and equity awards in the forms and proportions that we believe will motivate our executive officers to increase stockholder value over the long term.

Our executive compensation program is designed to achieve the following specific objectives:

Executive Compensation Program Framework

For 2023, the principal elements of our executive compensation program are summarized in the following table and described in detail in “Executive Compensation Components” below.

We also offer our executive officers the opportunity to participate in our 401(k) plan, health care insurance, flexible spending accounts, employee stock purchase plan and certain other benefits available generally to all of our full-time employees.

Governance of Executive Compensation Program

Role of Our Compensation Committee and our Board

Our Compensation Committee, which operates under a written charter adopted by the Board, is primarily responsible for reviewing and approving or recommending to the Board the compensation arrangements for our executive officers. In carrying out these responsibilities, the Compensation Committee reviews all components of executive officer and director compensation for consistency with our compensation philosophy as in effect. The Compensation Committee’s review of the base salary levels, annual cash incentive compensation opportunities, and long-term equity incentive compensation opportunities of our executive officers, including the NEOs, generally occurs around the beginning of the year, or more frequently as warranted. To date, our Compensation Committee has not established any formal policies or guidelines for allocating compensation between short-term and long-term compensation, between cash and non-cash compensation, or among different forms of non-cash compensation. However, as described above, our Compensation Committee seeks to provide a significant portion of our executive officer compensation in the form of variable, at-risk pay.

Our Compensation Committee or the independent members of the Board approve executive compensation decisions after taking into account these recommendations and such other factors as they deem relevant and as further described below. Typically, executive compensation adjustments to cash compensation are effective in the first quarter of the year.

Role of Our Executive Officers

In connection with its review and approval or recommendations, our Compensation Committee considers the recommendations of our Chief Executive Officer regarding the compensation of our executive officers who report directly to him. These recommendations generally include annual adjustments to compensation levels and an assessment of each executive officer’s overall individual contribution, scope of responsibilities and level of experience. While our Compensation Committee retains discretion to set executive officer compensation, it gives considerable weight to our Chief Executive Officer recommendations because of his direct knowledge of each executive officer’s performance and contribution to our business.

No other executive officer participates in the determination or recommendation of the amount or form of executive officer compensation, but our Board or our Compensation Committee may discuss with our Chief Executive Officer or Chief Financial Officer our financial, operating and strategic business objectives, incentive targets or performance goals. The Board or the Compensation Committee reviews and determines the appropriateness of the financial measures and performance goals, as well as assesses the degree of difficulty in achieving specific incentive targets and performance goals.

Role of Compensation Consultant

The Compensation Committee engages an independent compensation consultant to assist it by providing information, analysis, and other advice relating to our executive compensation program and the decisions resulting from its executive compensation review. In 2023, the Compensation Committee retained Pearl Meyer to serve as its independent executive compensation consultant and review the competitiveness of our compensation program for our senior executive officers and non-employee directors. Pearl Meyer also advises the Compensation Committee regarding various other executive and director compensation issues, as requested.

No member of our management team participated in the Compensation Committee’s decision to retain Pearl Meyer. Pearl Meyer reports directly to the Compensation Committee, and the Compensation Committee may replace Pearl Meyer or hire additional consultants at any time. Pearl Meyer attends meetings of the Compensation Committee, as requested, and communicates with the Compensation Committee Chairperson between meetings; however, the Compensation Committee, or the independent members of the Board, make all decisions regarding the compensation of our executives.

Pearl Meyer provides various compensation consulting services to the Compensation Committee with respect to our executives and other key employees pursuant to a written consulting agreement with the Compensation Committee. The services Pearl Meyer provides under the agreement include advising the Compensation Committee on the principal aspects of the Company’s executive compensation program including evolving best practices and providing market information and analysis regarding the competitiveness of the Company’s executive compensation program design.

Competitive Positioning

In 2023, the Compensation Committee approved a group of peer group companies (the “Compensation Peer Group”). The Compensation Peer Group included similarly-situated medical device and diagnostic companies that were identified by Pearl Meyer as companies with similar financial and growth characteristics and as competitors for executive talent based generally on the following criteria:

The Compensation Peer Group consisted of 19 companies that met the industry criteria and financial criteria. The following 19 companies comprised the Compensation Peer Group plan to be used to set compensation for 2023:

Certain information regarding the size and value of the Compensation Peer Group companies relative to us is set forth below (based on estimated information in June 2023).

In making its 2023 compensation decisions, the Compensation Committee evaluated the target annual total direct compensation (annual base salary, annual cash incentives and long-term equity incentive) for each of our executive officers, including our NEOs, who were employed with us when we set annual compensation in 2023 (other than Mr. Sergesketter). In determining its recommendations for the Board on executive compensation, the Compensation Committee reviewed the market consensus data provided by Pearl Meyer. The Compensation Committee reviewed the market consensus data for each executive officer’s base salary and annual target cash incentive and for each executive officer’s long-term equity incentives noting most fall within the desired 50th percentile. In conducting its evaluation, the Compensation Committee also considered, among other factors, company performance, each element of compensation, the compensation package as a whole, each executive officer’s past and expected future contribution to our business and our financial performance, and internal pay equity based on the impact on the business and performance, and retention.

We believe that this design allows us to meet the objectives of our executive compensation program, including attracting and retaining talented executives, while retaining flexibility to tailor compensation based on individual circumstances.

The Compensation Committee also reviewed market data provided by Pearl Meyer in negotiations with Mr. Smith and Mr. Bourque in setting their new hire compensation package in 2023 and 2024, respectively. Market data was one factor among the other factors described above that the Compensation Committee considered in designing a compensation package that was competitive and would recruit and retain each of these executives as a key executive to our business.

Executive Compensation Elements

Base Salary

We provide an annual base salary to each of our executive officers, including our NEOs, to compensate each of them for services rendered during the year. Salaries are reviewed annually by the Compensation Committee or, at the request of the committee, the independent members of our Board, and adjusted for the ensuing year based on (i) both qualitative and quantitative factors such as company performance, job level, responsibilities and prior experience and expertise, individual performance, and future potential, (ii) internal review of the executive officer’s total compensation, individually and relative to our other executive officers with similar levels of responsibility within our organization and (iii) an evaluation of the compensation levels of similarly-situated executive officers in our Compensation Peer Group and in our industry generally.

Mr. Smith's base salary was established through arm's length negotiation in connection with his hire in 2023.

In setting the salaries of our other NEOs base salaries for 2023, we considered the recommendations of the Chief Executive Officer regarding the compensation of each of the NEOs who reported directly to him, the NEOs role and responsibilities within the Company, and such other factors described above. We also considered the 50th percentile as a general guideline for the appropriate level of base salaries but do not attempt to benchmark base salary to any specific percentile. We believe that this approach to setting base salary levels allows us to be competitive, while retaining flexibility to tailor compensation based on individual circumstances.

Given the amount of transition amongst our management team and to save costs, none of our NEOs who were NEOs during 2022 received a base salary increase in 2023, except in the case of Dr. Glezer due to a change mid-year in his responsibilities.

The 2023 base salaries for our NEOs were as follows:

Cash Incentive Compensation

Overview of 2023 Incentive Plan. We maintained a cash executive incentive compensation plan for 2023 (the “2023 Incentive Plan”) for our eligible, non-commissioned employees, including our executive officers (other than Mr. Sergesketter). Mr. Sergesketter was not eligible to receive any bonuses during his employment, other than the completion bonus described in the “Employment Agreements” section below.

The 2023 Incentive Plan was designed to increase stockholder value and our success by motivating our employees, including our participating NEOs, to perform to the best of their abilities and achieve our objectives. The Compensation Committee determined the performance goals applicable to target awards under the 2023 Incentive Plan.

Target Cash Incentive Opportunities. Except for Mr. Sergesketter, each of our executive officers, including each of our NEOs, was assigned a target annual incentive compensation opportunity under the 2023 Incentive Plan, which was calculated as a percentage of his or her annual base salary as of the end of 2023.

The annual cash incentive compensation opportunities and actual payouts of the NEOs for fiscal 2023 were:

2023 Incentive Plan Performance Goals. For fiscal 2023, we updated the 2023 Incentive Plan to measure metrics based on the corporate performance objectives of revenue (weighted 55%), Adjusted EBITDA (weighted 20%) and individual performance goals (weighted 25%). The 2023 Incentive Plan allowed for the following add-backs related to revenue and Adjusted EBITDA: 1) Stock-based compensation, 2) currency adjusted to restate Euro-denominated revenue using plan current rates, 3) restructuring-related and other charges, 4) relocations or sign-on bonuses, 5) acquisition-related expenses or divestiture costs, 6) litigation settlements greater than $1 million, and 7) other non-ordinary events in accordance with the Company's policies. We continued to use revenue and Adjusted EBITDA to provide incentives for our employees to drive both revenue and earnings growth and make adjustments to exclude certain non-cash and other expenses that are not indicative of our core operating results. We also added individual performance goals which were generally aligned to the strategic capabilities and business goals necessary to position the company for the future. The 2023 Incentive Plan funded based on our actual achievement against each metric set forth below:

The Compensation Committee reserved the right to increase, decrease, or eliminate any incentive payment that may be payable under the 2023 Incentive Plan, based on the factors it deemed relevant.

2023 Incentive Plan Achievement

Our 2023 results were revenue of $315.7 million (resulting in a percentage achievement of 0%) and Adjusted EBITDA was a negative $37.8 million (resulting in a percentage achievement of 0%). Accordingly, the 2023 Incentive Plan funded at an aggregate weighted payout percentage of 0% of target and our eligible executive officers, including our eligible NEOs, received payment under the 2023 Incentive Plan at 25% of target levels based on individual performance goals, which were determined to be achieved at target for most of the NEOs. The actual amount of each eligible NEO’s payment under the 2023 Incentive Plan is also set forth in the “Non-Equity Incentive Plan Compensation” column in the Summary Compensation Table beginning on page 62.

Long-Term Incentive Compensation - Annual Equity Grants

We believe long-term incentive compensation is an effective means of focusing our executive officers, including the NEOs, on driving improved financial performance and increased stockholder value over a multi-year period, provides a meaningful reward for long-term value creation, and motivates them to remain employed with us.

This approach aligns the contributions of our executive officers with the long-term interests of our stockholders and allows them to participate in any future appreciation in our common stock.

In 2023, we determined long-term incentive compensation for Messrs.
