Q:	How can I get electronic access to the proxy materials?

A:	The Company’s proxy materials are available at www.proxyvote.com and at http://ir.aldeyra.com. Our website address is included for reference only. The information contained on our website is not incorporated by reference into this proxy statement. You can find directions on how to instruct us to send future proxy materials to you by email at www.proxyvote.com. Choosing to receive future proxy materials by email will save us the cost of printing and mailing documents to you and will reduce the impact of our annual meetings on the environment. If you choose to receive future proxy materials by email, you will receive an email message next year with instructions containing a link to those materials and a link to the proxy voting website. Your election to receive proxy materials by email will remain in effect until you terminate it.

Q:	What information is contained in this proxy statement?

A:	The information in this proxy statement relates to the proposals to be voted on at the Annual Meeting, the voting process, the compensation of our directors and certain of our executive officers, corporate governance, and certain other required information.

Q:	Where is the Annual Meeting?

A:	The Annual Meeting will be held at the offices of Aldeyra Therapeutics, Inc., 131 Hartwell Avenue, Lexington, MA 02421.

Q:	Can I attend the Annual Meeting?

A:	You are invited to attend the Annual Meeting if you were a stockholder of record or a beneficial owner as of April 12, 2021 (the Record Date). Admission will begin at 7:30 a.m. local time on the date of the Annual Meeting, and you must present valid picture identification such as a driver’s license or passport and, if asked, provide proof of stock ownership as of the Record Date. The use of mobile phones, pagers, recording or photographic equipment, tablets and/or computers is not permitted at the Annual Meeting. The meeting will begin promptly at 8:00 a.m. local time.


Q:	What happens if a change to the location of the Annual Meeting is necessary due to exigent circumstances?

A:	As part of our precautions regarding the COVID-19 pandemic, we are planning for the possibility that we will conduct a virtual annual meeting. In the event it is not possible or advisable to hold our Annual Meeting in person or at the current noted location, we will announce alternative arrangements for the meeting as promptly as practicable, which may include holding the meeting solely by means of remote communication or at a different physical location. Please monitor the investor relations section of our website at https://ir.aldeyra.com for updated information concerning the location of the meeting and be sure to check the website prior to attending the meeting. In the event the meeting is held virtually, it will be important to retain the control numbers set forth on your proxy card or voting instruction form in order to verify your identity when accessing the virtual meeting. As always, we encourage you to vote your shares prior to the annual meeting. In the event the meeting is held virtually, the proxy card included with the proxy materials previously distributed will not be updated to reflect the change in location and may continue to be used to vote your shares in connection with the meeting.

Stock Ownership

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

A:	Stockholders of record - If your shares are registered directly in your name with our transfer agent, American Stock Transfer & Trust Company, LLC (AST), you are considered, with respect to those shares, the “stockholder of record,” and the Notice was provided to you directly by us. 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 in person at the Annual Meeting. Beneficial owners - Many Aldeyra stockholders hold their shares through a broker, trustee or other nominee, rather than directly in their own name. If your shares are held in a brokerage account or by a bank or another nominee (commonly referred to as being held in “street name”), you are considered the “beneficial owner” of such shares. The Notice was forwarded to you by your broker, trustee or nominee who is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to direct your broker, trustee or nominee on how to vote your shares. Beneficial owners are also invited to attend the Annual Meeting. However, since beneficial owners are not stockholders of record, you may not vote your shares in person at the Annual Meeting unless you follow your broker’s procedures for obtaining a legal proxy. If you request a printed copy of the proxy materials by mail, your broker or nominee will provide a voting instruction card for you to use.

Quorum and Voting

Q:	How many shares must be present or represented to conduct business at the Annual Meeting?

A:	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 Bylaws and Delaware state law. The presence, in person or by proxy, of a majority of the aggregate voting power of the issued and outstanding shares of stock entitled to vote generally in the election of directors will constitute a quorum at the meeting. A proxy submitted by a stockholder may indicate that the shares represented by the proxy are not being voted with respect to a particular matter. Under the General Corporation Law of the State of Delaware, abstentions and broker “non-votes” are counted as present and entitled to vote and are, therefore, included for purposes of determining whether a quorum is present at the Annual Meeting. 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 with respect to that item and has not received instructions from the beneficial owner.

Q:	Who is entitled to vote at the Annual Meeting?

A:	Holders of record of our common stock at the close of business on the Record Date are entitled to receive notice of and to vote their shares at the Annual Meeting. As of the Record Date, we had 47,543,812 shares of common stock outstanding. In deciding all matters at the Annual Meeting, each holder shares of our common stock will be entitled to one vote for each share of common stock held as of the close of business on the Record Date. We do not have cumulative voting rights for the election of directors.


Q:	How can I vote my shares in person at the Annual Meeting?

A:	Shares held in your name as the stockholder of record may be voted in person at the Annual Meeting. Shares held beneficially in street name may be voted in person at the Annual Meeting only if you obtain a legal proxy from the broker, trustee or other nominee that holds your shares giving you the right to vote the shares. Even if you plan to attend the Annual Meeting, we recommend that you also submit your proxy card, if you have requested one, or following the voting directions described below, so that your vote will be counted if you later decide not to attend the meeting.

Q:	How can I vote my shares without attending the Annual Meeting?

A:	Stockholder of record - If you are a stockholder of record, there are three ways to vote without attending the Annual Meeting: •Via the Internet - You may vote by proxy via the Internet by following the instructions provided in the Notice or, if you requested printed copies of the proxy materials by mail, by following the instructions provided in the proxy card. •By Telephone - You may vote by proxy by telephone by following the instructions provided in the Notice or, if you requested printed copies of the proxy materials by mail, by calling the toll free number found on the proxy card. •By Mail - If you request printed copies of the proxy materials by mail, you will receive a proxy card and you may vote by proxy by filling out the proxy card and returning it in the envelope provided. Beneficial owners - If you are a beneficial owner holding shares through a bank, broker or other nominee, please refer to your Notice or other information forwarded by your bank or broker to see which voting options are available to you.

Q:	What happens if I do not give specific voting instructions?

A:	Stockholder of record - If you are a stockholder of record and you: •Indicate when voting via the Internet or by telephone that you wish to vote as recommended by our Board of Directors; or •Sign and return a proxy card without giving specific voting instructions, then the persons named as proxy holders will vote your shares in the manner recommended by our Board of Directors on all matters presented in this proxy statement and as the proxy holders may determine in their discretion with respect to any other matters properly presented for a vote at the Annual Meeting. Beneficial owners - If you are a beneficial owner of shares held in street name and do not provide the organization that holds your shares with specific voting instructions then, under applicable rules, the organization that holds your shares may generally vote on “routine” matters but cannot vote on “non-routine” matters. If the organization that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter, that organization will inform the inspector of election that it does not have the authority to vote on this matter with respect to your shares. This is generally referred to as a “broker non-vote.”

Q:	What proposals will be voted on at the Annual Meeting?

A:	The following chart sets for the proposals scheduled for a vote at the Annual Meeting, our Board of Directors recommendation with respect to such proposals, the vote required for such proposals to be approved and whether broker discretionary voting is allowed on such proposal.
Proposal			Board Recommendation	Vote Required	Broker Discretionary Voting Allowed
Proposal 1:		Elect two directors to serve as Class I directors until the 2024 Annual Meeting of Stockholders	FOR	Plurality	No

Proposal 2:		Ratify the appointment of BDO USA, LLP as Aldeyra Therapeutics, Inc.’s independent registered public accounting firm for the year ending December 31, 2021.	FOR	Plurality	Yes

Proposal 3:		Approve, on a non-binding, advisory basis, the compensation of our named executive officers.	FOR	Plurality	No

Plurality means that the nominees for director receiving the greatest number of votes will be elected. Withheld votes and “broker non-votes” will have no effect on the election of a nominee. Broker Discretionary Voting occurs when a broker does not receive voting instructions from the beneficial owner and votes those shares in its discretion on any proposal on which it is permitted to vote. Even though your vote on Proposal 3 is advisory and therefore will not be binding on the Company, the Board of Directors or its compensation committee will review the voting results and take them into consideration when making future decisions regarding executive compensation of our named executive officers.



Q:	What happens if additional matters are presented at the Annual Meeting?

A:	If any other matters are properly presented for consideration at the Annual Meeting, including, among other things, consideration of a motion to adjourn the Annual Meeting to another time or place (including, without limitation, for the purpose of soliciting additional proxies), the persons named in the proxy card and acting thereunder will have discretion to vote on those matters in accordance with their best judgment. We do not currently anticipate that any other matters will be raised at the Annual Meeting.

Q:	Can I change or revoke my vote?

A:	Subject to any rules your broker, trustee or nominee may have, you may change your proxy instructions at any time before your proxy is voted at the Annual Meeting. If you are a stockholder of record, you may change your vote by (1) filing with our Corporate Secretary, prior to your shares being voted at the Annual Meeting, a written notice of revocation or a duly executed proxy card, in either case dated later than the prior proxy card relating to the same shares, or (2) by attending the Annual Meeting and voting in person (although attendance at the Annual Meeting will not, by itself, revoke a proxy). A stockholder of record that has voted via the Internet or by telephone may also change his or her vote by later making a timely and valid Internet or telephone vote. If you are a beneficial owner of shares held in street name, you may change your vote (1) by submitting new voting instructions to your broker, trustee or other nominee or (2) if you have obtained a legal proxy from the broker, trustee or other nominee that holds your shares giving you the right to vote the shares, by attending the Annual Meeting and voting in person. Any written notice of revocation or subsequent proxy card must be received by our Corporate Secretary prior to the taking of the vote at the Annual Meeting. Such written notice of revocation or subsequent proxy card should be hand delivered to our Corporate Secretary or should be sent so as to be delivered to our principal executive offices, Attention: Corporate Secretary.

Q:	Who will bear the cost of soliciting votes for the Annual Meeting?

A:	We will bear all expenses of this solicitation, including the cost of preparing and mailing these proxy materials. We may reimburse brokerage firms, custodians, nominees, fiduciaries and other persons representing beneficial owners of common stock for their reasonable expenses in forwarding solicitation material to such beneficial owners. Our directors, officers and employees may also solicit proxies in person or by other means of communication. Such directors, officers and employees will not be additionally compensated but may be reimbursed for reasonable out-of-pocket expenses in connection with such solicitation. We may engage the services of a professional proxy solicitation firm to aid in the solicitation of proxies from certain brokers, bank nominees and other institutional owners. Our costs for such services, if retained, will not be significant. If you choose to access the proxy materials and/or vote through the Internet, you are responsible for any Internet access charges you may incur.

Q:	Is my vote confidential?

A:	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 Aldeyra 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.

Q:	Where can I find the voting results of the Annual Meeting?

A:	We intend to announce preliminary voting results at the Annual Meeting and will publish final results in a current report on Form 8-K within four business days after the Annual Meeting.

Stockholder Proposals and Director Nominations

Q:	What is the deadline to propose actions for consideration at next year’s annual meeting of stockholders or to nominate in individuals to serve as directors?

A:	You may submit proposals, including director nominations, for consideration at future stockholder meetings. Requirements for stockholder proposals to be considered for inclusion in our proxy materials - Stockholders may present proper proposals for inclusion in our proxy statement and for consideration at our next annual meeting of stockholders by submitting their proposals in writing to our Corporate Secretary in a timely manner. In order to be included in the proxy statement for the 2022 annual meeting of stockholders, stockholder proposals must be received by our Corporate Secretary no later than December 16, 2021, and must otherwise comply with the requirements of Rule 14a-8 of the Securities Exchange Act of 1934, as amended (the Exchange Act).


	Requirements for stockholder proposals to be brought before an annual meeting - In addition, our bylaws establish an advance notice procedure for stockholders who wish to present certain matters before an annual meeting of stockholders. In general, nominations for the election of directors may be made by our Board of Directors or any committee thereof or any stockholder, who is a stockholder of record on the date of the giving of such notice and on the record date for the determination of stockholders entitled to vote at such meeting, who is entitled to vote at such meeting and who has delivered written notice to our Corporate Secretary no later than the Notice Deadline (as defined below), which notice must contain specified information concerning the nominees and concerning the stockholder proposing such nominations. Our bylaws also provide that the only business that may be conducted at an annual meeting is business that is (1) specified in the notice of meeting (or any supplement thereto) given by or at the direction of our Board of Directors, (2) otherwise properly brought before the meeting by or at the direction of our Board of Directors (or any committee thereto) or (3) properly brought before the meeting by a stockholder who has delivered written notice to our Corporate Secretary no later than the Notice Deadline (as defined below). The “Notice Deadline” is defined as that date which is not less than 90 days nor more than 120 days prior to the one year anniversary of the previous year’s annual meeting of stockholders. As a result, the Notice Deadline for the 2022 annual meeting of stockholders is between February 8, 2022 and March 10, 2022. If a stockholder who has notified us of his or her intention to present a proposal at an annual meeting does not appear to present his or her proposal at such meeting, we need not present the proposal for vote at such meeting. Recommendation of director candidates - You may recommend candidates to our Board of Directors for consideration by our nominating/corporate governance committee by following the procedures set forth below in “Corporation Governance - Board Committees - nominating/corporate governance committee.”

Q:	How may I obtain a copy of the bylaw provisions regarding stockholder proposals and director nominations?

A:	A copy of the full text of the bylaw provisions discussed above may be obtained by writing to our Corporate Secretary. A copy of our bylaws is posted on the investor relations section of our website at http://ir.aldeyra.com. All notices of proposals by stockholders, whether or not included in our proxy materials, should be sent to our principal executive offices, Attention: Corporate Secretary.

Additional Information about the Proxy Materials

Q:	Why did I receive a notice regarding the availability of proxy materials on the Internet instead of a full set of proxy materials?

A:	In accordance with the rules of Securities and Exchange Commission (SEC), we have elected to furnish our proxy materials, including this proxy statement and the 2020 Annual Report, to our stockholders primarily via the Internet. Beginning on or about April 14, 2021, we mailed to our stockholders a “Notice of Internet Availability of Proxy Materials” that contains notice of the Annual Meeting and instructions on how to access our proxy materials on the Internet, how to vote at the meeting, and how to request printed copies of the proxy materials. Stockholders may request to receive all future proxy materials in printed form by mail or electronically by e-mail by following the instructions contained at www.proxyvote.com. We encourage stockholders to take advantage of the availability of the proxy materials on the Internet to help reduce the environmental impact of our annual meetings.

Q:	What does it mean if multiple members of my household are stockholders but we only received one Notice or full set of proxy materials in the mail?

A:	We have adopted a procedure called “householding,” which the SEC has approved. Under this procedure, we 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 costs, mailing costs, and fees. Stockholders who participate in householding will continue to be able to access and receive separate proxy cards. Upon written request, we will deliver promptly 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 of the Notice and, if applicable, the proxy materials, stockholders should send their requests to our principal executive offices, Attention: Corporate Secretary. Stockholders who hold shares in street name (as described below) may contact their brokerage firm, bank, broker-dealer, or other similar organization to request information about householding.


Q:	What is the mailing address for Aldeyra’s principal executive offices?

A:	Our principal executive offices are located at 131 Hartwell Avenue, Suite 320, Lexington, Massachusetts 02421. The telephone number at that location is 781-761-4904.

Any written requests for additional information, copies of the proxy materials and 2020 Annual Report, notices of stockholder proposals, recommendations for candidates to our Board of Directors, communications to our Board of Directors or any other communications should be sent to the address above.

Our Board of Directors is currently comprised of seven members who are divided into three classes with staggered three-year terms. In January 2021, Jesse I. Treu, Ph.D. resigned as a member of the Board of Directors and the authorized number of directors was reduced to seven. A director serves in office until his or her respective successor is duly elected and qualified or until his or her earlier death or resignation. This classification of the Board of Directors into three classes with staggered three-year terms may have the effect of delaying or preventing changes in our control or management. Your proxy cannot be voted for a greater number of persons than the number of nominees named in this proxy statement.

Nominees of Election as Class I Directors at the Annual Meeting

This year’s nominees for election to the Board of Directors as our Class I directors to serve for a term of three years expiring at the 2024 annual meeting of stockholders, or until their successors have been duly elected and qualified or until their earlier death, resignation or removal, are provided below. All of the nominees listed below are currently directors of the Company. The age of each director as of April 12, 2021 is set forth below. Each of the nominees has agreed to serve as a director if elected, and we have no reason to believe that any nominee will be unable to serve if elected.

PROPOSAL 2

RATIFICATION OF THE APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


General

Our audit committee has appointed the firm of BDO USA, LLP, independent registered public accountants, to audit our financial statements for the year ending December 31, 2021. BDO USA, LLP has audited our financial statements since the fiscal year ended December 31, 2013.

Notwithstanding its selection and even if our stockholders ratify the selection, our audit committee, in its discretion, may appoint another independent registered public accounting firm at any time during the year if the audit committee believes that such a change would be in the best interests of Aldeyra and its stockholders. At the Annual Meeting, the stockholders are being asked to ratify the appointment of BDO USA, LLP as our independent registered public accounting firm for the year ending December 31, 2021. Our audit committee is submitting the selection of BDO USA, LLP to our stockholders because we value our stockholders’ views on our independent registered public accounting firm and as a matter of good corporate governance. Representatives of BDO USA, LLP are expected to be present at the Annual Meeting and they will have an opportunity to make statements and will be available to respond to appropriate questions from stockholders.

If this proposal does not receive the affirmative approval of a majority of the votes cast on the proposal, the audit committee would reconsider the appointment.

Principal Accounting Fees and Services

The following table sets forth all fees paid or accrued by us for professional audit services and other services rendered by BDO USA, LLP during the years ended December 31, 2020 and 2019:

		2020	2019

Audit-Related Fees		-	-

Pre-Approval of Audit and Non-Audit Services

Consistent with requirements of the SEC and the Public Company Accounting Oversight Board regarding auditor independence, our audit committee is responsible for the appointment, compensation and oversight of the work of our independent registered public accounting firm. In recognition of this responsibility, our audit committee (or the chair if such approval if needed on a time urgent basis) generally pre-approves of all audit and permissible non-audit services provided by the independent registered public accounting firm. These services may include audit services, audit-related services, tax services and other services.

OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” RATIFICATION OF THE APPOINTMENT OF BDO USA, LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE YEAR ENDING DECEMBER 31, 2021.

PROPOSAL 3

ADVISORY VOTE ON EXECUTIVE COMPENSATION

In accordance with Section 14A of the Exchange Act and as a matter of good corporate governance, our Board of Directors is providing the stockholders with the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of our named executive officers as described in the section below entitled “Executive Officer Compensation” and accompanying compensation tables, and as discussed in the related narrative disclosure below. This advisory vote is commonly referred to as a “say-on-pay” vote. Stockholders may express their views on the design and effectiveness of our executive compensation program by voting “For” or “Against” approval, on a non-binding, advisory basis, of the compensation of our named executive officers, or may abstain. This vote is not intended to address any specific element of compensation, but rather the overall compensation of the named executive officers.

The goal of our executive compensation program is to enable us to attract, recruit and retain qualified employees who have the collective and individual abilities necessary to run our business to meet the challenges we face, and to focus those executives on achieving results that enhance the value of our stockholders’ investment. Annual variable compensation and long-term equity incentives are significant components of our executive compensation program, and are designed to focus our executive team on those financial goals that we believe are most closely related to stockholder value. We believe our compensation policies and procedures demonstrate a strong link between pay and performance. Please read the section below entitled “Executive Officer Compensation” and the compensation tables and narrative that follow for additional details about our executive compensation program, including information about the fiscal 2020 compensation of named executive officers.

The affirmative vote from the holders of a majority of the shares present in person, or represented by proxy at the Annual Meeting is required to approve, on a non-binding, advisory basis, the compensation of our named executive officers. Abstentions and broker non-votes will have the same effect as a vote “Against” this matter.

Because say-on-pay votes are advisory and non-binding, voting results cannot overrule any decisions made by the Board of Directors or compensation committee. However, the compensation committee will take into account the outcome of the vote when considering future compensation arrangements for our named executive officers.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” APPROVAL, ON A NON-BINDING, ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.



CORPORATE GOVERNANCE

Code of Conduct

Our Board of Directors adopted a code of business conduct that applies to each of our directors, officers and employees. The full text of our code of business conduct is posted on the investor relations section of our website at http://ir.aldeyra.com. Any waiver of the code of business conduct for an executive officer or director may be granted only by our Board of Directors or a committee thereof and must be timely disclosed as required by applicable law. We have implemented whistleblower procedures that establish formal protocols for receiving and handling complaints from employees. Any concerns regarding accounting or auditing matters reported under these procedures will be communicated promptly to the audit committee.

Board Composition

Our business affairs are managed under the direction of our Board of Directors, which is currently composed of seven members. All of our directors, other than Dr. Brady, are independent within the meaning of the listing rules of The Nasdaq Stock Market (Nasdaq). Our Board of Directors is divided into three classes with staggered three-year terms. At each annual meeting of stockholders, the successors to directors whose terms then expire will be elected to serve from the time of election and qualification until the third annual meeting following election. Directors in a particular class will be elected for three-year terms at the annual meeting of stockholders in the year in which their terms expire. As a result, only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Each director’s term continues until the election and qualification of his or her successor, or the earlier of his or her death, resignation or removal. The classification of our Board of Directors may have the effect of delaying or preventing changes in our control or management.

Director Independence

Our common stock is listed on The Nasdaq Capital Market. The listing rules of this stock exchange generally require that a majority of the members of a listed company’s Board of Directors be independent. In addition, the rules of Nasdaq require that, subject to specified exceptions, each member of a listed company’s audit, compensation, and nominating/corporate governance committees be independent. The Nasdaq director independence definition includes a series of objective tests, such as that the director is not also one of our employees and has not engaged in various types of business dealings with us. In addition, as further required by Nasdaq rules, our Board of Directors has made a subjective determination as to each independent director that no relationships exist which, in the opinion of our Board of Directors, would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In making these determinations, our directors reviewed and discussed information provided by the directors and us with regard to each director’s business and personal activities as they may relate to us and our management. Our Board of Directors has determined that none of our non-employee 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 Nasdaq. The independent members of our Board of Directors hold separate regularly scheduled executive session meetings at which only independent directors are present. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the Board of Directors, or any other board committee: accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries; or be an affiliated person of the listed company or any of its subsidiaries. Each of Martin J. Joyce, M.B.A., Gary Phillips, M.D. and Ben R. Bronstein, M.D. qualify as an independent director pursuant to Rule 10A-3.

Board Leadership Structure

Our Board of Directors is currently led by its chairman, Dr. Douglas. Our Board of Directors recognizes that it is important to determine an optimal board leadership structure to ensure the independent oversight of management as the company continues to grow. We separate the roles of chief executive officer and chairman of the Board of Directors in recognition of the differences between the two roles. The chief executive officer is responsible for setting the strategic direction for the company and the day-to-day leadership and performance of the company, while the chairman of the Board of Directors presides over meetings of the full Board of Directors. We believe that this separation of responsibilities provides a balanced approach to managing the Board of Directors and overseeing the company. Our Board of Directors has concluded that our current leadership structure is appropriate at this time. However, our Board of Directors will continue to periodically review our leadership structure and may make such changes in the future as it deems appropriate.

Board Committees

Our Board of Directors has established an audit committee, a compensation committee, a nominating/corporate governance committee and a stock option committee. The composition of these committees meets the criteria for independence under, and the functioning of these committees comply with the applicable requirements of the Sarbanes-Oxley Act of 2002, the current rules of The Nasdaq Capital Market and SEC rules and regulations. We intend to comply with future requirements as they become applicable to us. Each committee has the composition and responsibilities described below.


Audit Committee

During our year ended December 31, 2020, our audit committee held 4 meetings. The current members of our audit committee are Martin J. Joyce, M.B.A., Ben R. Bronstein, M.D. and Gary Phillips, M.D., each of whom is a non-employee member of the Board of Directors. Mr. Joyce serves as the chair of the audit committee. Dr. Phillips replaced Jesse Treu, Ph.D. as a member of our audit committee following Dr. Treu’s resignation as a director in January 2021. The audit committee’s main function is to oversee our accounting and financial reporting processes, internal systems of control, independent registered public accounting firm relationships and the audits of our financial statements. Pursuant to the audit committee charter, the functions of the committee include, among other things: •appointing, approving the compensation of, and assessing the independence of our registered public accounting firm; •overseeing the work of our registered public accounting firm, including through the receipt and consideration of reports from such firm; •reviewing and discussing with management and the registered public accounting firm our annual and quarterly financial statements and related disclosures; •monitoring our internal control over financial reporting and our disclosure controls and procedures; •meeting independently with our registered public accounting firm and management; •preparing the audit committee report required by SEC rules; •reviewing and approving or ratifying any related person transactions; and •overseeing our risk assessment and risk management policies. All members of our audit committee meet the requirements for financial literacy under the applicable rules and regulations of the SEC and The Nasdaq Capital Market. Our Board of Directors has determined that Mr. Joyce is an “audit committee financial expert” as defined by applicable SEC rules and has the requisite financial sophistication as defined under the applicable Nasdaq rules and regulations.

Compensation Committee

During our year ended December 31, 2020, our compensation committee held 1 meeting. The current members of our compensation committee are Neal S. Walker, D.O., Gary Phillips, M.D. and Nancy Miller-Rich. Gary Phillips, M.D. serves as the chair of the compensation committee. Neal S. Walker, D.O. replaced Ben R. Bronstein, M.D. as a member of our compensation committee in January 2021. Our compensation committee reviews and recommends policies relating to compensation and benefits of our officers and employees. Pursuant to the compensation committee charter, the functions of this committee include: •evaluating the performance of our chief executive officer and determining the chief executive officer’s salary and contingent compensation based on his or her performance and other relevant criteria; •identifying the corporate and individual objectives governing the chief executive officer’s compensation; •in consultation with the chief executive officer, determining the compensation of our other officers; •making recommendations to our Board of Directors with respect to director compensation; •reviewing and approving the terms of material agreements with our executive officers; •overseeing and administering our equity incentive plans and employee benefit plans; •reviewing and approving policies and procedures relating to the perquisites and expense accounts of our executive officers; •if and as applicable, furnishing the annual compensation committee report required by SEC rules; and •conducting a review of executive officer succession planning, as necessary, reporting its findings and recommendations to our Board of Directors, and working with the Board of Directors in evaluating potential successors to executive officer positions. Our Board of Directors has determined that each of Neal S. Walker, D.O., Gary Phillips, M.D. and Nancy Miller-Rich is independent under the applicable rules and regulations of Nasdaq, is a “non-employee director” as defined in Rule 16b-3 promulgated under the Exchange Act. Our chief executive officer and chief financial officer assist our compensation committee in carrying out its functions, although they do not participate in deliberations or decisions with respect to their own compensation. Since January 2015, our compensation committee has engaged the services of Pearl Meyer & Partners, LLC (Pearl Meyer), a compensation consulting firm, to advise the compensation committee regarding the amount and types of compensation that we provide to our executives and directors and how our compensation practices compared to the compensation practices of other companies. Pearl Meyer reports directly to the compensation committee. Pearl Meyer does not provide any services to us other than the services provided to the compensation committee. The compensation committee believes that Pearl Meyer does not have any conflicts of interest in advising the compensation committee under applicable SEC rules or Nasdaq listing standards.


Nominating/Corporate Governance Committee

During our year ended December 31, 2020, our nominating/corporate governance committee held 3 formal meetings and had a number of ad hoc discussions between one or more members of the committee. The current members of our nominating/corporate governance committee are Martin J. Joyce, M.B.A., Ben Bronstein, M.D. and Richard H. Douglas, Ph.D. Ben Bronstein, M.D. serves as the chair of the nominating/corporate governance committee. Dr. Bronstein replaced Jesse Treu Ph.D. as a member and chair of our nominating/corporate governance committee following Dr. Treu’s resignation as a director in January 2021. Pursuant to the nominating/corporate governance committee charter, the functions of this committee include, among other things: •identifying, evaluating, and making recommendations to our Board of Directors and our stockholders concerning nominees for election to our Board of Directors, to each of its committees and committee chairs; •annually reviewing the performance and effectiveness of our Board of Directors and developing and overseeing a performance evaluation process; •annually evaluating the performance of management, the Board of Directors and each board committee against their duties and responsibilities relating to corporate governance; •annually evaluating adequacy of our corporate governance structure, policies, and procedures; and •generally advising the Board of Directors on corporate governance matters. Our nominating/corporate governance committee believes that candidates for director should have certain minimum qualifications, including being able to read and understand basic financial statements and having a general understanding of our Company’s industry and market. Our nominating/corporate governance committee also considers other factors it deems appropriate, including, but not limited to: •the candidate’s relevant expertise and experience upon which to offer advice and guidance to management; •the candidate having sufficient time to devote to the affairs of the Company; •the candidate having a proven track record in his or her field; •the candidate’s ability to exercise sound business judgment; •the candidate’s commitment to vigorously represent the long-term interests of our stockholders; •whether or not a conflict of interest exists between the candidate and our business; •whether the candidate would be considered independent under applicable Nasdaq and SEC standards; •the current composition of the Board of Directors; and •the operating requirements of the Company. In conducting this assessment, the nominating/corporate governance committee considers diversity, gender, age, skills and such other factors as it deems appropriate given the then-current needs of the Board of Directors and the Company, to maintain a balance of knowledge, experience and capability. While diversity and variety of experiences and viewpoints represented on the Board of Directors should always be considered, the nominating/corporate governance committee believes that a director nominee should not be chosen nor excluded solely or largely because of race, color, gender, national origin or sexual orientation or identity. In the case of incumbent directors whose terms of office are set to expire, the nominating/corporate governance committee reviews such directors’ overall service to the Company during their term, including the number of meetings attended, level of participation, quality of performance, and any other relationships and transactions that might impair such directors’ independence. When there is a vacancy on the Board of Directors, the nominating/corporate governance committee uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems it appropriate, a professional search firm. The nominating/corporate governance committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board of Directors. The nominating/corporate governance committee meets to discuss and consider such candidates’ qualifications and then selects a nominee for recommendation to the Board of Directors by majority vote. Our nominating/corporate governance committee will consider director candidates recommended by stockholders and evaluate them using the same criteria as candidates identified by the Board of Directors or the nominating/corporate governance committee for consideration. If a stockholder of the Company wishes to recommend a director candidate for consideration by the nominating/corporate governance committee, the stockholder recommendation should be delivered to the Corporate Secretary of the Company at the principal executive offices of the Company, and must include information regarding the candidate and the stockholder making the recommendation as required by our Bylaws.

Stock Option Committee

During our year ended December 31, 2020, our stock option committee did not hold any meetings. The sole member of our stock option committee is Todd C. Brady, M.D., Ph.D. Pursuant to the stock option committee charter, the function of this committee includes, among other things, granting stock options to non-executive employees under our 2013 Equity Incentive Plan within certain grant guidelines specified in the stock option committee charter or as adopted from time to time by our Board of Directors or compensation committee. Guidelines include, but are not limited to, a cap of 250,000 options to any individual and 3,000,000 shares in the aggregate in any single calendar year.

Compensation Committee Interlocks and Insider Participation

None of the members of our compensation committee is or has in the past 7 years served as 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 of any entity that has one or more executive officers serving on our Board of Directors or compensation committee.



Meetings of the Board of Directors

The full Board of Directors held 6 meetings during our year ended December 31, 2020. No director attended fewer than 75% of the total number of meetings of the Board of Directors and any committees of the Board of Directors of which he or she was a member during our year ended December 31, 2020. It is our policy that directors are invited and encouraged to attend our annual meetings of stockholders. We expect to schedule our annual meetings on the same day as a regularly scheduled Board of Directors meeting in order to facilitate attendance by the members of our Board of Directors. One of our then-serving, directors attended our 2020 annual meeting of stockholders. The lower than normal attendance of our then-serving directors was due to the 2020 annual meeting of stockholders being in person during the COVID-19 pandemic.

Board Oversight of Risk

Our Board of Directors has responsibility for the oversight of the company’s risk management processes and, either as a whole or through its committees, regularly discusses with management our major risk exposures, their potential impact on our business and the steps we take to manage them. The risk oversight process includes receiving regular reports from board committees and members of senior management to enable our Board of Directors to understand the company’s risk identification, risk management and risk mitigation strategies with respect to areas of potential material risk, including operations, finance, legal, regulatory, strategic and reputational risk. The audit committee reviews information regarding liquidity and operations, and oversees our management of financial risks. Periodically, the audit committee reviews our policies with respect to risk assessment, risk management, loss prevention and regulatory compliance. Oversight by the audit committee includes direct communication with our external auditors, and discussions with management regarding significant risk exposures and the actions management has taken to limit, monitor or control such exposures. The compensation committee is responsible for assessing whether any of our compensation policies or programs has the potential to encourage excessive risk-taking. The nominating/corporate governance committee manages risks associated with the independence of the Board of Directors, corporate disclosure practices, and potential conflicts of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire board is regularly informed through committee reports about such risks. Matters of significant strategic risk are considered by our Board of Directors as a whole.

In addition, the following rules apply to initial and annual equity awards: •All of the awards will be automatically granted to each non-employee director in the form of non-statutory stock options issued under our 2013 Equity Incentive Plan; •The number of shares subject to a stock option is determined by using the Black-Scholes option valuation method to determine the value per option on the valuation date (the exercise price shall be the closing price of our common stock on the third trading day prior to the grant date); •All of the non-employee directors’ equity awards will become fully vested upon a Change in Control (as defined below) of our company; and •All such automatic director option grants to non-employee directors shall have a maximum term of ten years. For purposes of our non-employee director compensation plans or programs, a non-employee director is a director who is not employed by us and who does not receive compensation from us or have a business relationship with us that would require disclosure under certain rules of the SEC. We also reimburse our non-employee directors for their reasonable out-of-pocket expenses incurred in attending Board of Directors and committee meetings. Change in Control means the occurrence of any of the following: (a) any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) becomes the “beneficial owner” (as defined in Rule 13d-3 of the Exchange Act), directly or indirectly, of our securities representing more than fifty percent (50%) of the total voting power represented by our then-outstanding voting securities; (b) the consummation of the sale or disposition by us of all or substantially all of our assets; (c) the consummation of a merger or consolidation of our company with or into any other entity, other than a merger or consolidation which would result in the voting securities of our company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or its parent) more than fifty percent (50%) of the total voting power represented by the voting securities of our company or such surviving entity or its parent outstanding immediately after such merger or consolidation; or (d) individuals who are members of our Board of Directors (the Incumbent Board) cease for any reason to constitute a majority of the members of our Board of Directors over a period of 12 months; provided, however, that if the appointment or election (or nomination for election) of any new member of our Board of Directors was approved or recommended by a majority vote of the members of the Incumbent Board then still in office, such new member shall, for purposes hereof, be considered as a member of the Incumbent Board. A transaction shall not constitute a Change in Control under the definition set forth in the preceding sentence if its sole purpose is to change the state of our incorporation or to create a holding company that will be owned in substantially the same proportions by the persons who held our securities immediately before such transaction. In addition, if a Change in Control constitutes a payment event with respect to any equity or other benefit that provides for a deferral of compensation and which is subject to Section 409A of the Internal Revenue Code of 1986, as amended (the Code), then notwithstanding anything to the contrary in this letter agreement or in any document governing such award, the transaction with respect to such equity or other benefit must also constitute a “change in control event” as defined in Treasury Regulation Section 1.409A-3(i)(5) to the extent required by Section 409A of the Code.

“Good Reason” means a resignation within 12 months after one of the following conditions has come into existence without the officer’s consent, but only if such officer has provided us with written notice of such condition within 90 days after it has come into existence and we have failed to cure such condition within 30 days after we receive such notice:

•a reduction in such executive officer’s base salary or target bonus by more than 10%;

•a material reduction of such executive officer’s authority, duties or responsibilities; or

•a relocation of such executive officer’s principal workplace by more than 50 miles.

In March 2017, the compensation committee of our Board of Directors approved and established the CIC Plan, which provides for the accelerated vesting for outstanding unvested equity awards held by our eligible employees who are subject to a qualifying employment termination in connection with a change in control, including our executive officers. The CIC Plan provides for acceleration of 100% of the unvested equity held by our executive officers in the event the officer’s employment is terminated without cause, or the officer resigns for good reason, in each case within 3 months before or 12 months following a change in control. In connection with the adoption of the CIC Plan, Dr. Brady waived the “single trigger” acceleration of his equity awards on consummation of a change in control provided for in his offer letter. In addition, the CIC Plan shall replace any and all change of control provisions provided for in the equity or equity based awards granted to Dr. Brady prior to the establishment of the CIC Plan.

For the purpose of the CIC Plan, the following terms have the definitions set forth below:

A termination for “cause” means termination by us of the executive officer’s employment by reason of the occurrence of any one or more of the following: (i) an act or acts of personal dishonesty taken by the executive officer and intended to result in substantial personal enrichment of the executive officer at the expense of the Company; (ii) repeated violations by the executive officer of the executive officer’s duties and obligations (other than as a result of incapacity due to physical or mental illness) which are demonstrably willful and deliberate on the executive officer’s part, which are committed in bad faith or without reasonable belief that such violations are in the Company’s best interests and which are not remedied in a reasonable period of time after receipt of written notice from the Company; (iii) indictment or plea of nolo contendere of the executive officer of a felony involving moral turpitude; or (iv) the material breach of the executive’s proprietary information and inventions agreement.

“Change in Control” means the occurrence of any of the following: (i) any “person” (as such term is used in Sections 13(d) and 14(d) of the Exchange Act) becomes the “beneficial owner” (as defined in Rule 13d-3 of the Exchange Act), directly or indirectly, of our securities representing more than fifty percent (50%) of the total voting power represented by our then-outstanding voting securities; (ii) the consummation of the sale or disposition by us of all or substantially all of our assets; (iii) the consummation of a merger or consolidation of our company with or into any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity or its parent) more than fifty percent (50%) of the total voting power represented by the voting securities of our company or such surviving entity or its parent outstanding immediately after such merger or consolidation; or the Incumbent Board ceases for any reason to constitute a majority of the members of our Board of Directors over a period of 12 months; provided, however, that if the appointment or election (or nomination for election) of any new member of our Board of Directors was approved or recommended by a majority vote of the members of the Incumbent Board then still in office, such new member shall, for purposes of the CIC Plan, be considered as a member of the Incumbent Board. A transaction shall not constitute a Change in Control under the definition set forth in the preceding sentence if its sole purpose is to change the state of our incorporation or to create a holding company that will be owned in substantially the same proportions by the persons who held our securities immediately before such transaction.

“Good reason” means (i) a material diminution in the executive officer’s base salary or target bonus by more than 10%, except in connection with company-wide cost reduction; (ii) a material diminution in the executive officer’s authority, duties or responsibilities with respect to our company or any successor or acquiring entity, including, without limitation, any requirement that an officer who is our chief executive officer report to anyone other than to the Board of Directors of the ultimate parent entity of the Company (the “Ultimate Parent”) or that an executive officer (other than our chief executive officer) report to anyone other than the chief executive officer of the Ultimate Parent; (iii) a breach of a material provision of the executive officer’s employment or other written agreement governing employment with us (it being understand that a change in title without the executive officer’s consent shall be a material breach); or (iv) a relocation of the executive officer’s principal workplace by more than 50 miles from where the executive officer performed services prior to the relocation, without the executive officer’s prior consent. However, good reason shall not exist unless (i) the executive officer has given written notice to us within 90 days of the initial existence of the good reason event or condition(s) giving specific details regarding the event or condition; (ii) we have failed to cure such event or condition within 30-days of receiving such notice, and (iii) the executive officer resigns within 30 days of the expiration of the 30-day cure period provided for in clause (ii) provided that we have not cured the event or condition.


Employee Benefits and Perquisites

Our named executive officers will be eligible to participate in our health and welfare plans to the same extent as all other full-time employees. We do not provide our named executive officers with perquisites or other personal benefits other than reimbursement of certain healthcare premiums, as described in the Summary Compensation Table.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

In addition to the compensation arrangements with our directors and executive officers described elsewhere in this proxy statement, the following is a description of each transaction since January 1, 2020 and each currently proposed transaction in which:

•we have been or are to be a participant;

•the amount involved exceeds the lesser of $120,000 or one percent of the average of our total assets at yearend for the last two completed fiscal years; and

•any of our directors, executive officers or holders of more than 5% of our capital stock, or any immediate family member of or person sharing the household with any of these individuals (other than tenants or employees), had or will have a direct or indirect material interest.

Employment Agreements

We have entered into offer letters with our named executive officers. For more information regarding these agreements, see the section of this prospectus entitled “Executive Compensation - Narrative Disclosure to Compensation Tables.”

Indemnification Agreements

We have entered into separate indemnification agreements with our directors and executive officers, in addition to indemnification provided for in our amended and restated certificate of incorporation and amended and restated bylaws. These agreements, among other things, provide for indemnification of our directors and executive officers for certain expenses, judgments, fines and settlement amounts, among others, incurred by this person in any action or proceeding arising out of this person’s services as a director or executive officer in any capacity with respect to any employee benefit plan or as a director, partner, trustee or agent of another entity at our request. We believe that these provisions in our amended and restated certificate of incorporation and amended and restated bylaws and indemnification agreements are necessary to attract and retain qualified persons as directors and executive officers.

Equity Grants and Awards to Executive Officers and Directors

We have granted equity to our executive officers and certain of our directors as more fully described in the section entitled “Management - Director Compensation” and “Executive Compensation.”

Policies and Procedures for Related Party Transactions

Pursuant to our code of conduct and audit committee charter, any related party transaction or series of transactions with an executive officer, director, or any of such persons’ immediate family members or affiliates, in which the amount, either individually or in the aggregate, involved exceeds $120,000 must be presented to our audit committee for review, consideration and approval. All of our directors and executive officers are required to report to our audit committee any such related party transaction. In approving or rejecting the proposed transactions, our audit committee shall consider the relevant facts and circumstances available and deemed relevant to the audit committee, including, but not limited to the risks, costs and benefits to us, the terms of the transaction, the availability of other sources for comparable services or products and, if applicable, the impact on a director’s independence. Our audit committee shall approve only those transactions that, in light of known circumstances, are not inconsistent with Aldeyra’s best interests, as our audit committee determines in the good faith exercise of its discretion.

AUDIT COMMITTEE REPORT

The information contained in the following report of Aldeyra’s audit committee is not considered to be “soliciting material,” “filed” or incorporated by reference in any past or future filing by us under the Securities Exchange Act of 1934 or the Securities Act of 1933 unless and only to the extent that Aldeyra specifically incorporates it by reference.
