We will conduct a virtual online Annual Meeting so our stockholders can participate from any geographic location with Internet connectivity. We believe this will enhance accessibility to our Annual Meeting for all of our stockholders. Stockholders will be able to attend and participate in the Annual Meeting online, vote shares electronically, and submit questions prior to and during the Annual Meeting as described in the enclosed proxy statement. We are pleased to embrace the current technology available to provide expanded access and enable greater stockholder attendance and participation from any location around the world.

Our Annual Report to Stockholders includes our audited financial statements for 2023 (our “Annual Report”) and information about our operations, markets and products.

We are mailing to most of our stockholders a Notice of Internet Availability of Proxy Materials (the “Notice”) instead of a paper copy of the attached Proxy Statement and our Annual Report. The Notice contains instructions on how to access those documents over the Internet. The Notice also contains instructions on how to request a paper copy of our proxy materials, including the attached Proxy Statement, our Annual Report and a form of proxy card. All stockholders who request a paper copy of our proxy materials will receive a paper copy of the proxy materials by mail. It is anticipated that our proxy materials are being first mailed or made available to stockholders on or about May 20, 2024.

Your vote is important. Whether or not you plan to participate in the virtual online Annual Meeting, you can be sure your shares are represented at the meeting by promptly voting your shares as instructed in the Notice, or by requesting a printed proxy card, if you prefer, and completing, signing, dating and returning the printed proxy card by mail. If you later decide to participate in the Annual Meeting and wish to change your vote, you may do so simply by voting online during the meeting.

To log in to and participate in this year’s virtual Annual Meeting, you will need the stockholder control number and meeting password located on the Notice, on your proxy card or on the instructions that accompanied your proxy materials. Please keep this information in a safe place so it is available to you for the meeting.

INFORMATION ABOUT THE ANNUAL MEETING AND VOTING

General

This Proxy Statement contains information related to the 2024 Annual Meeting of Stockholders (the “Annual Meeting”) of Longeveron Inc. (“Longeveron,” the “Company,” “we,” “our” or “us”), which will be held on Tuesday, July 2, 2024, at 1:00 p.m. Eastern Time, and any postponements or adjournments thereof. We will host the Annual Meeting solely online via live webcast, so our stockholders can participate from any geographic location with Internet connectivity. We believe this will enhance accessibility to our Annual Meeting for all of our stockholders.

In accordance with Securities and Exchange Commission (“SEC”) rules, instead of mailing a printed copy of our proxy materials to each stockholder of record, we are furnishing proxy materials to our stockholders via the Internet. If you received a Notice of Internet Availability of Proxy Materials (the “Notice”) by mail, you will not receive a printed copy of the proxy materials other than as described below. The Notice contains instructions on how to access and review all of the important information contained in the proxy materials over the Internet. The Notice also instructs how you may submit your proxy over the Internet. If you received a Notice and would like to receive a printed copy of our proxy materials, including our Annual Report on Form 10-K (as amended), follow the instructions for requesting such materials included in the Notice.

Stockholders of record at the close of business on May 16, 2024 (the “Record Date”) are entitled to notice of and to vote at the Annual Meeting and any adjournment thereof. It is anticipated that the Notice will first be sent to stockholders, and this Proxy Statement and the form of proxy relating to our Annual Meeting, are being first mailed or made available to stockholders on or about May 20, 2024. These materials are available for viewing, printing and downloading on the Internet at www.colonialstock.com/longeveron2024.

Purpose of the Meeting

The specific proposals to be considered and acted upon at the Annual Meeting are summarized in the Notice of Annual Meeting of Stockholders accompanying this Proxy Statement and are described in more detail in this Proxy Statement. We are not aware of any matter to be presented other than those described in this Proxy Statement.

How to Participate in the Annual Meeting

The Annual Meeting will be a completely virtual meeting of stockholders, which will be conducted exclusively by webcast. You are entitled to participate in the Annual Meeting only if you were a stockholder of the Company as of the close of business on the Record Date, or if you hold a valid proxy for the Annual Meeting. No physical meeting will be held.

You will be able to attend the Annual Meeting online and submit your questions during the meeting by visiting www.colonialstock.com/longeveron2024. You also will be able to vote your shares online by attending the Annual Meeting by webcast. To participate in the Annual Meeting, you will need to enter the control number and meeting password included on your Notice, on your proxy card or on the instructions that accompanied your proxy materials.

Please also note that if you hold your shares in “street name” (that is, through a broker or other nominee), you may need to follow additional instructions provided by your broker in order to vote your shares and submit questions during the Annual Meeting.

The online meeting will begin promptly at 1:00 p.m. Eastern Time. We encourage you to access the meeting prior to the start time leaving ample time for the check in. Online access will begin at 12:30 p.m. Eastern Time. Please follow the registration instructions as outlined in this Proxy Statement.

Table of Contents

Voting

We have two classes of common stock outstanding: our outstanding Class A common stock, par value $0.001 per share (the “Class A Common Stock”) and our outstanding Class B common stock, par value $0.001 per share (the “Class B Common Stock,” which together with the Class A Common Stock is referred to in this Proxy Statement as the “Common Stock”). Holders of our Class A Common Stock and Class B Common Stock have identical rights, except that holders of our Class A Common Stock are entitled to one (1) vote for each share held of record and holders of our Class B Common Stock are entitled to five (5) votes for each share held of record on all matters submitted to a vote of the stockholders, including the election of directors. Stockholders do not have cumulative voting rights. Holders of our Class A Common Stock and Class B Common Stock vote together as a single class on all matters presented to the stockholders for their vote or approval, except as may otherwise be required by Delaware law. Class A Common Stockholders and Class B Common Stockholders of record on the Record Date are entitled to notice of and to vote at the Annual Meeting. As of the Record Date, 4,864,619 shares of Class A Common Stock representing the same number of votes and 1,484,005 shares of Class B Common Stock representing 7,420,025 votes were issued and outstanding. Thus, the presence at the Annual Meeting, in person or by proxy, of holders of Class A Common Stock or Class B Common Stock, or a combination thereof, representing at least 6,142,323 votes will be required to establish a quorum, which permits business to be conducted at the Annual Meeting. Abstentions and broker non-votes count as present for establishing a quorum but will not be counted as votes cast. If a quorum is not present, the meeting may be adjourned until a quorum is obtained.

What Vote is Required to Approve Each Item?

Election of Directors. The affirmative vote of a plurality of the votes cast at the Annual Meeting is required for the election of directors. A properly executed proxy marked “WITHHOLD” with respect to the election of one or more directors will not be voted with respect to the director or directors indicated, although it will be counted for purposes of determining whether there is a quorum.

Other Proposals. The affirmative vote of a majority of the votes cast at the Annual Meeting is required to amend the Longeveron 2021 Incentive Award Plan and to ratify the appointment of Marcum LLP as our independent registered public accounting firm for fiscal year 2024.

Treatment of Abstentions and Broker Non-Votes. Under Delaware law, an “abstain” vote is counted as present for the purposes of determining whether a quorum exists but is not considered a vote cast either for or against a proposal. As such, abstentions will not have any effect on the outcome of the proposals. A broker “non-vote” is counted as present for the purposes of determining whether a quorum exists. A broker “non-vote” occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power for that particular item and has not received instructions from the beneficial owner. A bank, broker or other nominee holding the shares of Common Stock in “street name” for a beneficial owner has discretion (but is not required) to vote the beneficial owner’s share of Common Stock with respect to “routine” matters if the beneficial owner does not provide voting instructions. The broker or other nominee, however, is not permitted to vote the beneficial owner’s share of Common Stock with respect to “non-routine” matters without voting instructions. A “broker non-vote” occurs when the broker or other nominee does not vote on a particular proposal because that broker or other nominee does not have discretionary voting power for that particular item and has not received instructions from the beneficial owner.

The first proposal at the Annual Meeting concerning the election of directors and the second proposal concerning the amendment to the 2021 Incentive Award Plan are considered non-routine. The third proposal at the Annual Meeting regarding ratification of our independent registered public accounting firm is routine. Accordingly, a bank, broker or other nominee that does not receive instructions from the beneficial owner will be entitled to vote such owner’s shares in its discretion solely on the third proposal (ratification of our independent registered public accounting firm) and will not have discretionary authority to vote on first proposal (election of directors) or the second proposal (amendment to the 2021 Incentive Award Plan). Broker non-votes will be considered to have no effect on the first and second proposal, and banks, brokers, or other nominees will be permitted to vote on the third proposal.

Table of Contents

Difference Between a “Stockholder of Record” and a Beneficial Owner of Shares Held in “Street Name”

Stockholder of Record. If your shares are registered directly in your name with our transfer agent, Colonial Stock Transfer, then you are considered the “stockholder of record” of those shares. In this case, your Notice or printed proxy materials have been sent to you directly by us. You may vote your shares by proxy prior to the Annual Meeting by following the instructions contained on the Notice or, if you received a printed version of the proxy materials by mail, by following the instructions provided with your proxy materials and on your proxy card.

Beneficial Owners of Shares Held in Street Name. If your shares are held in a brokerage account or by a bank, trust or other nominee or custodian, then you are considered the beneficial owner of those shares, which are held in “street name.” In this case, your proxy materials have been forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As the beneficial owner, you have the right to instruct that organization as to how to vote the shares held in your account by following the instructions contained on the voting instruction card provided to you by that organization.

How to Vote

The manner in which your shares may be voted depends on how your shares are held. If you are a stockholder of record, meaning that your shares are represented by certificates or book entries in your name so that you appear as a stockholder on the records of Colonial Stock Transfer, our stock transfer agent, you may vote by proxy, meaning you authorize the individuals named on your proxy card or Notice to vote your shares. If you choose to vote by proxy, you may do so by telephone, via the Internet or by mail. Each of these methods is explained below. If you hold your shares of Common Stock in multiple accounts, you should vote your shares as described in each set of proxy materials you receive. If no direction is made on your proxy and it is otherwise properly executed, your proxy will be voted FOR the election of the four director nominees, FOR the amendment to the 2021 Incentive Award Plan and FOR the ratification of our independent registered public accounting firm. You also may participate in and vote during the Annual Meeting.

Voting by proxy. You may vote your shares by proxy by telephone, via the Internet or by mail:

• By Telephone. You may transmit your proxy voting instructions by calling the telephone number specified on the Notice, or if you received a printed version of the proxy materials by mail, by following the instructions provided with your proxy materials and on your proxy card. You will need to have the Notice or proxy card in hand when you call. If you choose to vote by telephone, you do not have to return a proxy card by mail.

• Via the Internet. You may transmit your proxy voting instructions via the Internet by accessing the website specified on the Notice, or if you received a printed version of the proxy materials by mail, by following the instructions provided with your proxy materials and on your proxy card. You will need to have the Notice or proxy card in hand when you access the website. If you choose to vote via the Internet, you do not have to return a proxy card by mail.

• By Mail. If you received printed proxy materials, you may vote by proxy by completing, signing and dating the proxy card enclosed with your printed proxy materials and returning it in the enclosed prepaid envelope.

Voting online during the Annual Meeting: Stockholders who elect to participate in the Annual Meeting may vote online during the Annual Meeting by following the instructions provided. Even if you plan to attend the Annual Meeting, we urge you to vote your shares by proxy in advance of the Annual Meeting so that if you should become unable to attend the Annual Meeting your shares will still be voted in accordance with your direction.

Telephone and Internet voting for stockholders of record will be available up until voting has closed at the Annual Meeting, and mailed proxy cards must be received by July 1, 2024, in order to be counted at the Annual Meeting. If the Annual Meeting is adjourned or postponed, this deadline may be extended.

If your shares are held in “street name” (by a broker, bank, or other nominee), you are considered a “beneficial owner.” The voting deadlines and availability of telephone and Internet voting for beneficial owners of shares held in street name will depend on the voting processes of the organization that holds your shares. Therefore, we urge you to carefully review and follow the voting instruction card and any other materials that you receive from that organization.

Revoking a Proxy; Changing Your Vote

If you are a stockholder of record, you may revoke your proxy before the vote is taken at the meeting:

• by submitting a new proxy with a later date before the Annual Meeting either signed and returned by mail or transmitted using the telephone or Internet voting procedures described in the “How to Vote” section above;

• by voting online at the virtual meeting site; or

• by filing a written revocation with our corporate Secretary.

If your shares are held in “street name,” you may submit new voting instructions by contacting your broker or other organization holding your account. You may also vote online at the Annual Meeting, which will have the effect of revoking any previously submitted voting instructions, if you obtain a legal proxy from the organization that holds your shares as described in the “How to Vote” section above.

Your attendance alone at the Annual Meeting will not automatically revoke your proxy.

Solicitation

Our Board of Directors is soliciting proxies for the Annual Meeting as described in this Proxy Statement, and Longeveron will bear the entire cost of solicitation, including the preparation, assembly, printing and mailing of the Notice, this Proxy Statement, the proxy card and any additional solicitation materials furnished to the stockholders. Copies of solicitation materials will be furnished to brokerage houses, fiduciaries and custodians holding shares in their names that are beneficially owned by others so that they may forward the solicitation materials to such beneficial owners. We may reimburse such persons for their costs in forwarding the solicitation materials to such beneficial owners. In addition, the original solicitation of proxies by mail may be supplemented by a solicitation by Internet or other means by our directors, officers or employees. No additional compensation will be paid to these individuals for any such services, although we may reimburse reasonable out-of-pocket expenses.

Deadlines for Receipt of Stockholder Proposals

Rule 14a-8 Requirements. Stockholders may present proposals for action at a future meeting only if they comply with the requirements of the proxy rules established by the SEC and our Bylaws. Typically, for stockholder proposals submitted pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) to be presented at and included in our proxy statement for the following year’s Annual Meeting of Stockholders, such proposals must be submitted and received not less than 120 calendar days before the date the Company’s proxy statement was released to stockholders in connection with the previous year’s annual meeting. For the 2025 Annual Meeting, such proposals must be received by the Company no later than January 27, 2025.

Requirements of our Bylaws. Additionally, pursuant to our Bylaws, any stockholder intending to present a proposal for action at an annual meeting, including submission of a nomination for a director to the Board, must give written notice to the Company’s corporate Secretary not less than 90 days and not more than 120 days prior to the anniversary date of the prior year’s annual meeting, which for the 2025 Annual Meeting would be March 4 to April 3, 2025 except that if date of the annual meeting is more than 30 days before or more than 60 days after such anniversary date, then the deadline for submitting a stockholder proposal is the 90th day prior to such annual meeting, or if later, the close of business on the tenth day following the day on which such notice of the date of the meeting was mailed or such public disclosure was made. Stockholder proposals and nominations must be in writing and should be addressed to our corporate Secretary at our principal executive offices located at 1951 NW 7th Ave., Suite 520, Miami, Florida 33136. In addition, nominations of any person for election to the Board at an annual meeting must comply with the requirements set forth in Sections 2.5 and 2.6 of our Bylaws.

Table of Contents

Requirements of the Universal Proxy Rules. In addition to satisfying the foregoing requirements under our Bylaws, to comply with the universal proxy rules, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice that sets forth the information as required by Rule 14a-19 under the Exchange Act no later than April 14, 2025. These requirements are separate from and in addition to the SEC’s requirements that a stockholder must meet in order to have a stockholder proposal included in the Company’s proxy statement, as discussed above. The Chairman of the Annual Meeting reserves the right to reject, rule out of order, or take other appropriate action with respect to any proposal that does not comply with these and other applicable requirements, including conditions set forth in our Bylaws and conditions established by the Securities and Exchange Commission.

We have not been notified by any stockholder of his or her intent to present a stockholder proposal from the floor at this year’s Annual Meeting. Your proxy grants the proxy holders discretionary authority to vote on any matter properly brought before the Annual Meeting that is not included in this Proxy Statement.

MATTERS TO BE CONSIDERED AT ANNUAL MEETING

PROPOSAL 1:
ELECTION OF DIRECTORS

Our Amended and Restated Certificate of Incorporation and Bylaws provide for our Board of Directors (the “Board”) to be divided into three classes. Each class of directors serves for a three-year term, with one class being elected by the Company’s stockholders at each annual meeting. Our Board currently has eight directors: Joshua Hare (Chair), Wa’el Hashad, Khoso Baluch, Neil Hare, Douglas Losordo, Richard Kender, Rock Soffer, and Ursula Ungaro. Jeffrey Pfeffer resigned from the Board on May 6, 2024, and Cathy Ross resigned from the Board on May 8, 2024, resulting in two vacancies on the Board. On May 10, 2024, the Board appointed Richard Kender to fill the vacancy created by Mr. Pfeffer’s resignation. Joshua Hare, Douglas Losordo, and Ursula Ungaro currently serve as directors with terms expiring at this year’s Annual Meeting. There is an additional vacancy to be filled at this year’s Annual Meeting as a result of Ms. Ross’s resignation. Neil Hare and Rock Soffer serve as directors with terms expiring at the 2025 annual meeting of stockholders; and Wa’el Hashad, Khoso Baluch, and Richard Kender serve as directors with terms expiring at the 2026 annual meeting of stockholders.

Four directors will be elected at the Annual Meeting to serve three-year terms expiring on the date of the annual meeting of stockholders to be held in 2027 (the “2027 Annual Meeting”) or until their respective successors shall have been elected and qualified. Dr. Losordo has communicated to the Board that he is not standing for re-election at this year’s Annual Meeting. As a result, the Governance and Nominating Committee of the Board of Directors has recommended to the Board for nomination, and the Board has nominated Mr. Joshua Hare, the Company’s current Chief Science Officer (CSO) and current Chairman of the Board, Ms. Ursula Ungaro, a current director, Mr. Roger Hajjar (who was recommended to the Board by Joshua Hare), and Ms. Neha Motwani (who was recommended to the Board by Khoso Baluch) as its nominees for election to the Board at the Annual Meeting. Your proxy will be voted unless authority is withheld or the proxy is revoked, FOR the election of Dr. Hare, Ms. Ungaro, Dr. Hajjar, and Ms. Motwani to hold office until the date of our 2027 Annual Meeting or until their respective successors have been duly elected and qualified or until in either case they earlier resign, become disqualified or disabled, or are otherwise removed. Each returned proxy cannot be voted for a greater number of persons than the nominees named on the proxy. In the unanticipated event that a nominee becomes unable or declines to serve at the time of the Annual Meeting, the proxies will be voted for a substitute person recommended by the Governance and Nominating Committee and approved by the Board. Each of Dr. Hare, Ms. Ungaro, Dr. Hajjar, and Ms. Motwani have agreed to serve if elected, and the Board has no reason to believe that they will be unavailable to serve.

DIRECTORS AND NOMINEES

Provided below is certain information with respect to each nominee for election as a director and each continuing director.

PROPOSAL 2:
APPROVAL OF AN AMENDMENT TO THE LONGEVERON 2021 INCENTIVE AWARD PLAN

We are asking stockholders to approve the second amendment and restatement of the Company’s 2021 Incentive Award Plan (the “2021 Plan” or the “Plan”) in order to increase the maximum number of shares authorized and available for issuance under the 2021 Plan by an additional 1,300,000 shares, for a total of 4,097,860 shares under the Plan (inclusive of amounts previously approved and issued). The 2021 Plan, which was initially approved by the Company’s stockholders at the Company’s 2022 Annual Meeting (with an amendment thereto being approved by the Company’s stockholders at the Company’s 2023 Annual Meeting), is a long-term incentive plan designed to attract and retain executive officers, other employees, non-employee directors and consultants of the Company who are important to the success and growth of the Company’s business, by providing such persons with incentives to help further align their interests with those of our stockholders.

A copy of the Second Amended and Restated 2021 Plan is attached to this Proxy Statement as Appendix A. The following table sets forth certain information about awards outstanding under our Plan.

2021 Plan	As of May 16, 2024
Total Stock Options Outstanding		37,511
Total Restricted Stock Unit Awards Outstanding (unvested shares remaining)		31,883
Weighted-Average Exercise Price of Stock Options Outstanding	$	49.74
Weighted-Average Remaining Duration of Stock Options Outstanding		2.0
Total Shares Available for Grant under the Plan		190,299
Total Common Stock Outstanding		6,348,624

Description of the 2021 Plan

The following summarizes the material terms of the 2021 Plan, and is qualified in its entirety by reference to the full text of the 2021 Plan, as further amended and restated to reflect the increase in maximum authorized and available shares set forth above, attached hereto as Appendix A.

Administration. The Plan is administered by the Compensation Committee of the Board of Directors (the “Plan Committee”) consisting of persons who are (i) “Outside Directors” within the meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended, or the Code, (ii) “non-employee directors” within the meaning of Rule 16b-3 of the Securities Exchange Act of 1934, as amended, (the “Exchange Act”), or Non-Employee Directors, and (iii) “independent” for purposes of any applicable listing requirements; provided, however, that the Board of Directors or the Plan Committee may delegate to a committee of one or more members of Company management who are not Outside Directors, the authority to grant awards to eligible persons who are not then subject to the requirements of Section 16 of the Exchange Act. If a member of the Plan Committee is eligible to receive an award under the Plan, such Plan Committee member shall have no authority hereunder with respect to his or her own award. Among other things, the Plan Committee has complete discretion, subject to the terms of the Plan, to determine the employees, non-employee directors and non-employee consultants to be granted awards under the Plan, the type of awards to be granted, the number of shares subject to each award, the exercise price under each option and the base price for each stock appreciation right (“SAR”), the term of each award, the vesting schedule for an award, the value of the shares underlying the award, and the required withholdings, if any. The Plan Committee is also authorized to construe the award agreements and may prescribe rules relating to the Plan.

Grant of Awards; Shares Available for Awards. The Plan provides for the grant of awards which are incentive stock options (“ISOs”), non-qualified stock options (“NQSOs”), restricted shares, restricted stock units, SARs, dividend equivalents, or other stock or cash based awards, or any combination of the foregoing, to employees, non-employee directors, and non-employee consultants of the Company or any of its subsidiaries (each a “participant”) (however, solely Company employees or employees of the Company’s present or future parent or subsidiaries, as defined in Sections 424(e) or (f) of the Code, respectively, and any other entities the employees of which are eligible to ISOs under the Code, are eligible for incentive stock option awards). No more than 100,000 shares may be issued pursuant to the exercise of ISOs. Shares awarded as restricted stock, restricted stock units, dividend equivalent rights, or other

Table of Contents

stock or cash-based awards, which convey the full value of the shares subject to the award, options and SARs count as one share for every share awarded. To the extent that an award (or portion of an award) lapses, expires, is cancelled, is terminated unexercised or ceases to be exercisable for any reason, or the rights of its holder terminate, any shares subject to such award shall be deemed not to have been issued for purposes of determining the maximum aggregate shares which may be issued under the Plan and shall again be available for the grant of a new award. Furthermore, shares delivered to the Company by a participant to satisfy the applicable exercise or purchase price of an award, and/or to satisfy any applicable tax withholding obligation (including shares retained by the Company from the award being exercised or purchased and/or creating the tax obligation) will, as applicable, become or again be available for award grants under the Plan. The Plan will continue in effect, unless sooner terminated, until the tenth (10th) anniversary of the date on which it is adopted by the Board of Directors (except as to awards outstanding on that date). The Board of Directors in its discretion may terminate the Plan at any time with respect to any shares for which awards have not theretofore been granted; provided, however, that the Plan’s termination shall not materially and adversely impair the rights of a holder, without the consent of the holder, with respect to any award previously granted.

Future new hires, non-employee directors and additional non-employee consultants are eligible to participate in the Plan as well. The number of awards to be granted to officers, non-employee directors, employees and non-employee consultants cannot be determined at this time as the grant of awards is dependent upon various factors such as hiring requirements and job performance.

Options. The term of each stock option shall be as specified in the option agreement; provided, however, that except for stock options which are ISOs, granted to an employee who owns or is deemed to own (by reason of the attribution rules applicable under Code Section 424(d)) more than 10% of the total combined voting power of all classes of shares of the Company or of any parent corporation or subsidiary corporation thereof (both as defined in Section 424 of the Code), within the meaning of Section 422(b)(6) of the Code (a “ten percent shareholder”), no option shall be exercisable after the expiration of ten (10) years from the date of its grant (five (5) years for an employee who is a ten percent shareholder).

The price at which a share may be purchased upon exercise of a stock option shall be determined by the Plan Committee; provided, however, that such option price (i) shall not be less than the fair market value of a share on the date such stock option is granted, and (ii) shall be subject to adjustment as provided in the Plan. The Plan Committee or the Board of Directors shall determine the time or times at which, or the circumstances under which, a stock option may be exercised in whole or in part, the time or times at which options shall cease to be or become exercisable following termination of the stock option holder’s employment or upon other conditions, the methods by which such exercise price may be paid or deemed to be paid, the form of such payment, and the methods by or forms in which shares will be delivered or deemed to be delivered to participants who exercise stock options.

Options which are ISOs shall comply in all respects with Section 422 of the Code. In the case of an ISO granted to a ten percent shareholder, the per share exercise price under such ISO (to the extent required by the Code at the time of grant) shall be no less than 110% of the fair market value of a share on the date such ISO is granted. ISOs may only be granted to employees of the Company or employees of one of the Company’s present or future parent or subsidiaries. In addition, the aggregate fair market value of the shares subject to an ISO (determined at the time of grant) which are exercisable for the first time by an employee during any calendar year under all plans of the Company and any parent corporation or subsidiary corporation thereof (both as defined in Section 424 of the Code) which provide for the grant of ISOs may not exceed $100,000. Any Option which specifies that it is not intended to qualify as an ISO or any Option that fails to meet the ISO requirements at any point in time will automatically be treated as a NQSO under the terms of the Plan.

Other Stock or Cash Based Awards. Pursuant to the terms of the applicable award agreement, an award of stock or other cash-based awards, entitles the holder to receive shares, cash, or other property to employees, non-employee directors or non-employee consultants, in each case subject to any conditions and limitations in the Plan. Such other stock or cash-based awards will also be available as a payment form in the settlement of other awards, as standalone payments and as payment in lieu of compensation to which a participant is otherwise entitled. Subject to the Plan, the Plan Committee will determine the terms and conditions of such other stock or cash-based awards, including any purchase price, performance goal, transfer restrictions, and vesting conditions, will be set for in the applicable award agreement.

Table of Contents

Restricted Stock Awards. A restricted stock award is a grant or sale of shares to the holder, subject to such restrictions on transferability, risk of forfeiture and other restrictions, if any, as the Plan Committee or the Board of Directors may impose, which restrictions may lapse separately or in combination at such times, under such circumstances (including based on future service requirements or the satisfaction of other conditions), in such instalments or otherwise, as the Plan Committee or the Board of Directors may determine at the date of grant or purchase or thereafter. If provided for under the restricted stock award agreement, a participant who is granted or has purchased restricted stock shall have all of the rights of a shareholder, including the right to vote the restricted stock and the right to receive dividends thereon (subject to any mandatory reinvestment or other requirement imposed by the Plan Committee or the Board of Directors or in the award agreement). During the restricted period applicable to the restricted stock, subject to certain exceptions, the restricted stock may not be sold, transferred, pledged, exchanged, hypothecated, or otherwise disposed of by the participant.

Restricted Stock Unit Awards. A restricted stock unit award provides for a grant of shares to be made to the holder upon the satisfaction of predetermined vesting requirements and may also provide the holder with a right to receive dividend equivalents. The Plan Committee shall set forth in the applicable restricted stock unit award agreement the vesting requirements which the holder would be required to satisfy before the holder would become entitled to payment and the number of units awarded to the holder. At the time of such award, the Plan Committee may, in its sole discretion, or at the holder’s election, defer the settlement of the award in a manner intended to comply with Section 409A. The holder of a restricted stock unit shall be entitled to receive one (1) share for each restricted stock unit subject to such restricted stock unit award, if and to the extent the holder satisfies the applicable vesting requirements. Such payment or distribution shall be made as soon as administratively practical after the vesting date, but in no event more than sixty (60) days after the applicable vesting date, except that the Company may delay payment as the Company reasonably determines is necessary to avoid a violation of applicable law.

Stock Appreciation Rights. A SAR provides the participant to whom it is granted the right to receive, upon its exercise, cash or shares equal to the excess of (A) the fair market value of the number of shares subject to the SAR on the date of exercise, over (B) the product of the number of shares subject to the SAR multiplied by the base value for the SAR, as determined by the Plan Committee or the Board of Directors. The Plan Committee shall set forth in the applicable SAR award agreement the terms and conditions of the SAR, including the base value for the SAR (which shall not be less than the fair market value of a share on the date of grant), the number of shares subject to the SAR and the period during which the SAR may be exercised and any other special rules and/or requirements which the Plan Committee imposes on the SAR. No SAR shall be exercisable after the expiration of ten (10) years from the date of grant.

Dividend Equivalent Rights. If the Plan Committee provides, a grant of restricted stock units may provide a Participant with the right to receive dividend equivalents. Dividend equivalents may be paid currently or credited to an account for the participant, settled in cash or shares and subject to the same restrictions on transferability and forfeitability as the restricted stock units with respect to which the dividend equivalents are granted and subject to other terms and conditions as set forth in the applicable award agreement.

Equity Restructuring. Subject to certain restrictions, the Plan provides for the adjustment of shares underlying awards previously granted if, and whenever, prior to the expiration or distribution to the holder of shares underlying an award theretofore granted, the Company shall effect an Equity Restructuring, defined in the Plan as a “non-reciprocal transaction between the Company and its stockholders, such as a stock dividend, stock split, spin-off or recapitalization through a large, nonrecurring cash dividend, that affects the number or kind of shares of Common Stock (or other securities of the Company) or the share price of Common Stock (or other securities of the Company) and causes a change in the per share value of the Common Stock underlying outstanding Awards.” In the event of an Equity Restructuring, the Plan Committee will equitably adjust each outstanding award as it deems appropriate to reflect the Equity Restructuring, which may include adjusting the number and type of securities subject to each outstanding award and/or the award’s exercise or grant price, granting new awards to participants, or making cash payments to participants. The Plan also provides discretion to the Plan Committee to take certain actions with respect to outstanding awards in the event of certain Corporate transactions, including any dividend or other distribution (whether in the form of cash, Common Stock, other securities, or other property), reorganization, merger, consolidation, combination, amalgamation, repurchase, recapitalization, liquidation, dissolution, or sale, transfer, exchange or other disposition

Table of Contents

of all or substantially all of the assets of the Company, or sale or exchange of Common Stock or other securities of the Company, Change in Control, issuance of warrants or other rights to purchase Common Stock or other securities of the Company, other similar corporate transaction or event. Such actions the Plan Committee may take include (i) the cancellation of any such Award in exchange for either an amount of cash or other property with a value equal to the amount that could have been obtained upon the exercise or settlement of the vested portion of such Award or realization of the Participant’s rights under the vested portion of such award, as applicable, (ii) the acceleration of any vesting schedule, notwithstanding anything to the contract in the Plan, (iii) providing that such award be assumed by the successor or survivor corporation, or a parent or subsidiary thereof, (iv) adjusting the number and type of shares subject to outstanding awards and/or the terms and conditions of (including the grant or exercise price), and the criteria included in outstanding awards, (v) replacing such awards with other rights or property, and/or (vi) providing that the award will terminate and cannot vest, be exercised, or become payable after the applicable event.

Amendment and Termination. The Plan shall continue in effect, unless sooner terminated pursuant to its terms, until the tenth (10th) anniversary of the date on which it is adopted by the Board of Directors (except as to awards outstanding on that date). The Plan Committee may amend, modify or terminate any outstanding award, including by substituting another award of the same or a different type, changing the exercise or settlement date, and converting an ISO to an NQSO. The participant’s consent to such action will be required unless (i) the action, taking into account any related action, does not materially and adversely affect the participant’s rights under the award, or (ii) the change is otherwise permitted pursuant to the Plan.

Certain U.S. Federal Income Tax Consequences of the Plan

The following is a general summary of certain U.S. federal income tax consequences under current tax law to the Company (to the extent it is subject to U.S. federal income taxation on its net income) and to participants in the Plan who are individual citizens or residents of the United States for federal income tax purposes (“U.S. Participants”) of awards granted under the Plan. This summary does not purport to cover all of the rules that may apply, including special rules relating to limitations on our ability to deduct certain compensation, special rules relating to deferred compensation, golden parachutes, U.S. Participants subject to Section 16(b) of the Exchange Act or the exercise of a stock option with previously acquired shares. This summary assumes that U.S. Participants will hold their shares as capital assets within the meaning of Section 1221 of the Code. In addition, this summary does not address the foreign, state or local or other tax consequences, or any U.S. federal non-income tax consequences, inherent in the acquisition, ownership, vesting, exercise, termination or disposition of an award under the Plan, or shares issued pursuant thereto. Participants are urged to consult with their own tax advisors concerning the tax consequences to them of an award under the Plan or shares issued thereunder pursuant to the Plan.

Nonstatutory Stock Options. A U.S. Participant generally does not recognize taxable income upon the grant of a NQSO. Upon the exercise of a NQSO, the U.S. Participant generally recognizes ordinary compensation income in an amount equal to the excess, if any, of the fair market value of the shares acquired on the date of exercise over the exercise price thereof. If the U.S. Participant later sells shares acquired pursuant to the exercise of a NQSO, the U.S. Participant recognizes a long-term or short-term capital gain or loss, depending on the period for which the shares were held. A long-term capital gain is generally subject to more favourable tax treatment than ordinary income or a short-term capital gain. The deductibility of capital losses is subject to certain limitations.

Incentive Stock Options. A U.S. Participant generally does not recognize taxable income upon the grant or the exercise, of an ISO; provided, however, upon the exercise of an ISO, the excess of the fair market value of the shares subject to the ISO over the exercise price is an item of tax preference for purposes of calculating a U.S. Participant’s alternative minimum tax. If the U.S. Participant disposes of the shares acquired pursuant to the exercise of an ISO more than two years after the date of grant and more than one year after the transfer of the shares to the U.S. Participant (the “ISO Holding Period”), the U.S. Participant generally recognizes a long-term capital gain or loss, and the Company will not be entitled to a deduction. However, if the U.S. Participant disposes of such shares prior to the end the ISO Holding Period, the U.S. Participant will recognize ordinary compensation income equal to the excess (if any) of the fair market value of such shares on the date of exercise (or, if less, the amount realized on the disposition of such shares) over the exercise price paid for such shares.

Table of Contents

Stock Appreciation Rights. A U.S. Participant generally does not recognize income upon the grant of a SAR. The U.S. Participant recognizes ordinary compensation income upon exercise of the SAR equal to the increase in the value of the underlying shares.

Performance Awards, and Performance Shares, Restricted Stock Units, Unrestricted Stock Award and Dividend Equivalents. A U.S. Participant generally does not recognize income on the receipt of a performance stock award, performance unit award, restricted stock unit award, unrestricted stock award or dividend equivalent rights award until a cash payment or a distribution of shares is received thereunder. At such time, the U.S. Participant recognizes ordinary compensation income equal to the excess, if any, of the fair market value of the shares or the amount of cash received over any amount paid therefor, and the Company generally will be entitled to a tax deduction such amount at such time.

Restricted Stock. A U.S. Participant who receives a restricted stock award generally recognizes ordinary compensation income equal to the excess, if any, of the fair market value of such shares at the time the restriction lapses over any amount paid for the shares. Alternatively, the U.S. Participant may make an election under Section 83(b) of the Code to be taxed on the fair market value of such shares at the time of grant.

Internal Revenue Code Section 409A. Awards under the Plan may, in certain instances, result in the deferral of compensation that is subject to the requirements of Section 409A of the Code. Generally, to the extent that any such award fails to meet the requirements of Section 409A, the regulations issued thereunder or an exception thereto, the award recipient will be subject to immediate taxation, interest and tax penalties in the year the award vests. While awards issued under the Plan are intended to be structured and administered in a manner that complies with the requirements of Section 409A of the Code, no assurance can be given that compensation will, in fact, satisfy the requirements of Section 409A.

Tax Effect for the Company; Limitations on Deduction. The Company will generally be entitled to a tax deduction in connection with awards under the Plan in an amount equal to the ordinary income realized by a U.S. Participant and at the time the U.S. Participant recognizes such income (for example, upon the exercise of a NQSO or the vesting of restricted stock). Section 162(m) of the Code, however, generally places a limit on the amount of compensation the Company can deduct in any one year for the Company’s chief executive officer, chief financial officer, and certain other executive officers and former executive officers. 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. While the Compensation Committee considers tax deductibility as one factor in determining executive compensation, the Compensation Committee also looks at other factors in making its decisions and retains the flexibility to award compensation that it determines to be consistent with the goals of our executive compensation program even if the awards are not deductible by the Company for tax purposes.

In addition, if a “change-in-control” of the Company causes compensation under the Company’s incentive plans, including awards under the Plan, to accelerate vesting or result in the attainment of performance goals, U.S. Participants could, in some cases, be considered to have received “parachute payments.” If so, any such participant could be subject to a 20% excise tax on the amount of “excess parachute payments” received and the Company’s tax deduction could be disallowed under Section 280G of the Code.

Because our executive officers and non-employee directors are eligible to receive awards under the Plan and will continue to be eligible to receive awards under the Plan as amended and restated, if the amendment and restatement of the Plan is approved by the Company’s stockholders at the Annual Meeting, they may be deemed to have a personal interest in the approval of this Proposal 2.

Marcum LLP (“Marcum”) has been engaged as the Company’s independent registered public accounting firm since March 2022.

This decision was approved by the Audit Committee of the Board of Directors pursuant to the authority of the Audit Committee as specified in its Charter. In the Form 8-K, the Company disclosed that the report of MSL on the Company’s financial statements for fiscal years ended December 31, 2021, and 2020 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, did not contain an adverse opinion or a disclaimer of opinion, nor was it qualified or modified as to uncertainty, audit scope or accounting principle.

In addition, the Company confirmed in the Form 8-K that, during the fiscal years ended December 31, 2021 and 2020, and the subsequent interim period through March 22, 2022, there were no (1) disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) between the Company and MSL on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which would have caused it to make reference to the subject matter of such a disagreement in connection with its audit reports on the Company’s financial statements for such years, or (2) reportable events (as described in Item 304(a)(1)(v) of Regulation S-K). The Company provided MSL with a copy of the required disclosures made in the Form 8-K prior to its filing and requested, in accordance with applicable practices, that MSL furnish a letter addressed to the SEC stating whether or not it agrees with the statements made herein, which letter was furnished by MSL and attached as Exhibit 16.1 to the Form 8-K, stating that MSL agrees with such statements.

This decision was approved by the Audit Committee in accordance with the authority of the Audit Committee as specified in its Charter. The 8-K also confirmed that during the fiscal years ended December 31, 2021 and 2020 and through March 22, 2022, neither the Company nor anyone on its behalf consulted with Marcum regarding (1) the application of accounting principles to a specified transaction, completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, and neither a written report nor oral advice was provided to the Company that Marcum concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue, or (2) any matter that was either the subject of a disagreement (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a reportable event (as described in Item 304(a)(1)(v) of Regulation S-K).
