    ELECTION OF DIRECTORS

  2. General

    General Our Board of Directors may establish the authorized number of directors from time to time by resolution. Our Board of Directors is currently comprised of eight members who are divided into three classes with staggered three-year terms. Martin J. Joyce has informed the Company that he will not stand for re-election at the Annual Meeting. Following the Annual Meeting, the size of our Board of Directors will either be decreased to seven directors with one Class III director, or our Board of Directors may appoint a new director to serve as the second Class III director. 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.

  17. General

    General 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 and occurs on an annual basis. Stockholders may express 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. We attempt to maintain a robust dialogue with the major shareholders who actively manage investment in Aldeyra. Our major stockholders have not expressed significant concerns about any aspect of our compensation, including the general design of our equity compensation program or our use of stock options, restricted stock units, performance-based cash units, and cash-based units as the primary long-term incentive vehicles. Since January 2015, our compensation committee has engaged the services of Pearl Meyer & Partners, LLC (Pearl Meyer), a nationally recognized compensation consulting firm, to advise the compensation committee regarding the amount and types of compensation that we provide to our executives and directors, and to compare our compensation practices to the compensation practices of other similar biotechnology companies. Pearl Meyer reports directly to the compensation committee. 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 stockholder investments. Annual variable compensation and long-term equity incentives, in terms of potential realizable cash value that is contingent on achievement of corporate goals and share price appreciation, represented an average over 75% of our named executive officer’s target direct compensation under our 2025 executive compensation program, and are designed to focus our executive team on those corporate 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 2025 compensation of our named executive officers.

  49. Non-Employee Director Compensation

    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 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 that 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 parent) more than fifty percent (50%) of the total voting power of the voting securities of our Company or such surviving entity or 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 the 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.

  58. Elements of Compensation

    Elements of Compensation Our executive compensation program is designed and administered under the direction and control of the compensation committee of our Board of Directors, which is made up solely of independent directors. Our compensation committee reviews and approves our overall executive compensation program, policies, practices, and metrics and sets the compensation of our executive officers, including our named executive officers. Our compensation committee has designed our executive compensation program with the goal of ensuring consistency with our short-term and long-term goals given the dynamic nature of our business and the market in which we compete for executive talent. When making compensation decisions for our named executive officers, our compensation committee also reviews and considers the peer group and other survey data to obtain a general understanding of current competitive compensation practices. During the year ended December 31, 2025, our executive officer compensation program consisted of a mix of (i) base salary, (ii) annual cash bonus based on achievement of predetermined corporate and operational goals, and (iii) long-term equity compensation. Annual variable compensation and long-term equity incentives, in terms of potential realizable cash value that is contingent on achievement of corporate goals and share price appreciation, represented an average over 75% of our named executive officer’s target direct compensation under our 2025 executive compensation program. We currently maintain an offer letter with Dr. Brady. The offer letter provides for the initial base salary for Dr. Brady and eligibility to receive an annual cash target bonus as determined by our Board of Directors or compensation committee, subject to the attainment of one or more pre-established performance goals established by our Board of Directors or compensation committee. The offer letter provides for at-will employment and, other than as set forth below under “Severance and Change in Control Benefits”, may be terminated at any time. Mr. Alfieri, our principal financial officer and principal accounting officer, is employed by Danforth and Danforth is compensated on an hourly basis in connection with services provided by Mr. Alfieri. See “Danforth Consulting Agreement” below for further discussion. In connection with the termination of his employment, we entered into a transition agreement with Dr. Machatha dated December 23, 2025 (the “Transition Agreement”). See “Machatha Transition Agreement” below for further discussion. Annual Base Salaries Dr. Brady and Dr. Machatha received a base salary to compensate them for services rendered to us during the year ended December 31, 2025. Base salaries for our named executive officers are initially determined as a result of negotiation between the executive and our management in consultation with, and subject to the approval of, our compensation committee. Our compensation committee sets base salaries with the intent to attract and retain our executive officers; reward satisfactory performance; and provide a minimum, fixed level of cash compensation reflecting skill set, experience, role, and responsibilities. Our compensation committee reviews base salaries annually, typically in the first quarter, and has discretion to provide increases based on our compensation committee’s understanding of current competitive pay practices, promotions, the recommendation of our Chief Executive Officer (except for his own salary), changes in responsibilities and performance, annual budget for increases, our overall financial and operational results, the general economy, length of tenure, internal pay fairness, recommendations from Pearl Meyer, and other factors our compensation committee deems appropriate. The following table presents the annual base salaries for each of our named executive officers for 2024 and 2025:

    | Name | 2024 Base Salary ($) | 2025 Base Salary ($) | | Todd C. Brady, M.D., Ph.D. | 591,631 | 700,000 | | Stephen G. Machatha, Ph.D. | 392,340 | 400,000 |

  60. Elements of Compensation

    Cash Bonuses Dr. Brady is, and, prior to termination of his employment, Dr. Machatha was eligible to receive annual cash bonuses based on the achievement of annual goals. Annual cash incentive bonuses are awarded under a performance-based compensation program and are designed to align the interests of our named executive officers and stockholders by providing compensation based on the achievement of pre-established corporate financial goals. Our annual cash incentive bonus compensation program promotes our pay for performance philosophy by providing all executives and other management-level corporate employees with direct financial incentives in the form of annual cash awards for achievement of certain corporate financial goals established and approved by our compensation committee at the start of the year. For named executive officers, our compensation committee sets individual target cash incentive amount based on employment agreement provisions, the recommendation of our Chief Executive Officer (except for his own target), internal pay fairness, our general understanding of current competitive pay practices, and other factors deemed appropriate. After evaluating the competitive positioning of total target cash compensation in the context of our overall compensation philosophy for named executive officers, in March 2025, our compensation committee approved the target bonus as a percentage of base salaries set forth in table below for the year ended December 31, 2025.

  61. Elements of Compensation

    | Name | Target Cash Incentive Award (% of Base Salary) | | Todd C. Brady, M.D., Ph.D. | 60% | | Stephen G. Machatha, Ph.D. | 40% |

  62. Elements of Compensation

    The actual annual bonus paid, if any, is calculated by multiplying annual base salary, target bonus percentage, and the percentage attainment of the corporate goals established by our compensation committee for such year. Our compensation committee is not required to determine bonuses based on this exact formula and reserves the right to consider other factors and adjust bonus amounts accordingly. Following review, discussion and revisions of corporate performance goals proposed by management, our compensation committee approved the 2025 corporate performance goals which were designed to drive corporate performance that we believed were challenging but also achievable. In March 2026, our compensation committee, with the assistance of management, evaluated the level of achievement for the 2025 corporate performance goals. Following this review and discussion, our compensation committee determined to award bonus at 45% of target and approved the following bonus payments for 2025:

    | Name | Bonus | | Todd C. Brady, M.D., Ph.D. | $189,000 |

    Mr. Alfieri is retained through Danforth pursuant to the terms of the Danforth Consulting Agreement. As such, Mr. Alfieri was not eligible to receive a bonus for services provided during the year ended December 31, 2025. Pursuant to the Transition Agreement, upon execution of the agreement, Dr. Machatha was entitled to a lump sum payment of $88,000, representing 50% of his potential 2025 bonus based on 110% of his target bonus and following the execution of an additional release of claims, was entitled to an additional lump sum payment of $88,000.

  66. Pay Versus Performance Disclosure

    Pay Versus Performance Disclosure As required by Item 402(v) of Regulation S-K, we are providing the following information regarding the relationship between the executive “compensation actually paid” to our principal executive officer (PEO) and our other named executive officers (NEO) and our financial performance for each of the last three completed fiscal years. In determining the “compensation actually paid” (CAP) to our NEOs, we are required to make various adjustments to amounts that have in prior years been reported in the Summary Compensation Table (SCT), as the SEC valuation methods for this disclosure differ from those required in the SCT. The values do not necessarily represent the actual compensation received by the NEOs nor how the Compensation Committee evaluates and determines executive compensation levels. For our NEOs other than our PEO, compensation is reported as an average.
