|
Record Date: |
April 10, 2026 |
|||
|
Quorum: |
A majority of the shares of all issued and outstanding stock entitled to vote on the record date must be present in person or represented by proxy to constitute a quorum. |
|||
|
Shares Outstanding: |
27,359,791 shares of common stock outstanding as of April 10, 2026. |
|||
|
Voting: |
There are four ways a stockholder of record can vote: |
|||
|
(1) |
By Internet: You may vote over the Internet by following the instructions provided in the Notice or, if you requested to receive your proxy materials by U.S. mail, by following the instructions on the proxy card. |
|||
|
(2) |
By Telephone: If you requested to receive your proxy materials by U.S. mail, you may vote by telephone by following the instructions on the proxy card. |
|||
|
(3) |
By Mail: If you requested to receive your proxy materials by U.S. mail, you may complete, sign and return the accompanying proxy card in the postage-paid envelope provided. |
|||
|
(4) |
Live: If you are a stockholder as of the record date and you attend the Annual Meeting virtually, you may vote live at the Annual Meeting. Submitting a proxy will not prevent stockholders from attending the Annual Meeting virtually, revoking their earlier-submitted proxy, and voting live at the Annual Meeting. |
|||
|
In order to be counted, proxies submitted by telephone or Internet must be received by 11:59 p.m. central time on June 8, 2026. Proxies submitted by U.S. mail must be received before the start of the Annual Meeting. |
||||
| Unless you direct otherwise through your proxy voting instructions, the persons named as proxies will vote all proxies received “for” the election of each nominee. If any nominee is unable or unwilling to serve at the time of the Annual Meeting, the persons named as proxies may vote for a substitute nominee chosen by the present board of directors. In the alternative, the proxies may vote only for the remaining nominees, leaving a vacancy on the board of directors. The board of directors may fill such vacancy at a later date or reduce the size of the board of directors. We have no reason to believe that any of the nominees will be unwilling or unable to serve if elected as a director. | ||||
|
If you hold your shares through a bank or broker, please follow their instructions. |
||||
|
Revoking Your Proxy |
Stockholders of record may revoke their proxies by attending the Annual Meeting and voting in person, by delivering an instrument in writing revoking the proxy or by delivering another duly executed proxy bearing a later date to our corporate secretary before the vote is counted or by voting again using the telephone or Internet before the cutoff time (your latest telephone or Internet proxy is the one that will be counted). If you hold shares through a bank or broker, you may revoke any prior voting instructions by contacting that firm. |
|||
|
Votes Required to Adopt Proposals |
Each share of our common stock outstanding on the record date is entitled to one vote on any proposal presented at the Annual Meeting: |
|||
|
For Proposal One, the nominees receiving the plurality of votes properly cast will be elected as directors. |
||||
|
For Proposal Two, a majority of the votes properly cast represented at a meeting at which a quorum is present is required to ratify the appointment of Grant Thornton LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026. |
||||
| Effect of Abstentions and Broker Non-Votes | Votes withheld from any nominee, abstentions, and “broker nonvotes” (i.e., where a broker has not received voting instructions from the beneficial owner and for which the broker does not have discretionary power to vote on a particular matter) are counted as present for purposes of determining the presence of a quorum. Shares voting “withheld” and broker non-votes have no effect on the election of directors. Abstentions and broker non-votes will have the effect of a vote “against” the appointment of Grant Thornton LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2026. | |
| Voting Instructions | If you complete and submit your proxy voting instructions, the persons named as proxies will follow your instructions. If you submit proxy voting instructions but do not direct how your shares should be voted on each item, the persons named as proxies will vote FOR the election of the nominees for director and FOR the ratification of the appointment of Grant Thornton LLP as our independent registered public accounting firm. The persons named as proxies will vote on any other matters properly presented at the Annual Meeting in accordance with their best judgment, although we have not received timely notice of any other matters that may be properly presented for voting at the Annual Meeting. | |
|
Voting Results |
We will announce preliminary results at the Annual Meeting. We will report final results by filing a Form 8-K within four business days after the Annual Meeting. If final results are not available at that time, we will provide preliminary voting results in the Form 8-K and will provide the final results in an amendment to the Form 8-K as soon as they become available. |
|
|
Additional Solicitation/Costs |
We are paying for the distribution of the proxy materials and solicitation of the proxies. As part of this process, we reimburse brokerage houses and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for forwarding proxy and solicitation materials to our stockholders. Proxy solicitation expenses that we will pay include those for preparation, mailing, returning and tabulating the proxies. Our directors, officers, and employees may also solicit proxies on our behalf in person, by telephone, email or facsimile, but they do not receive additional compensation for providing those services. |
|
|
Some banks, brokers, and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that only one copy of the Notice, Proxy Statement, and Annual Report on Form 10-K for the year ended December 31, 2025, as applicable, is being delivered to multiple stockholders sharing an address unless we have received contrary instructions. We will promptly deliver a separate copy of any of these documents to you if you write to us at Eton Pharmaceuticals, Inc., 21925 W. Field Parkway, Suite 235, Deer Park, Illinois 60010 Attn: Investor Relations, or call (847) 787-7361. |
||
|
If you want to receive separate copies of the Notice, Proxy Statement, or Annual Report on Form 10-K in the future, or if you are receiving multiple copies and would like to receive only one copy for your household, you should contact your bank, broker, or other nominee record holder, or you may contact us at the above address or telephone number. |
PROPOSAL ONE - ELECTION OF DIRECTORS
Director Nominees
Based on the recommendation of the nominating and corporate governance committee, our board of directors has nominated Jenn Adams and Charles J. Casamento for reelection as directors to serve for a three-year term ending at the 2029 annual meeting or until their successors are elected and qualified or until their earlier death, resignation or removal.
The biographies of each of the nominees and continuing directors below contain information regarding each such person’s service as a director, business experience, public director positions held currently or at any time during the last five years and the experiences, qualifications, attributes or skills that caused the nominating and corporate governance committee to determine that the person should serve as a director of the Company. In addition to the information presented below regarding each such person’s specific experience, qualifications, attributes and skills that led the board of directors and its nominating and corporate governance committee to the conclusion that he or she should serve as a director, we also believe that each of our directors has a reputation for integrity, honesty and adherence to high ethical standards. Each of our directors has demonstrated business acumen and an ability to exercise sound judgment, as well as a commitment of service to our Company and our board of directors. Finally, we value our directors’ experience in relevant areas of business management and on other boards of directors and board committees.
Our corporate governance guidelines also dictate that a majority of the board of directors consist of independent directors whom the board of directors has determined have no material relationship with the Company and who are otherwise “independent” directors under the published listing requirements of The NASDAQ Stock Market LLC (“Nasdaq”). The Company has determined that, with the exception of Sean E. Brynjelsen, our president and chief executive officer, all of our other directors qualify as “independent” directors.
Nominees for Election as Class II Directors for a Three-Year Term
Jenn Adams has served as a member of our board of directors since 2021. She is chief executive officer of August Bioservices LLC which provides research, pharmaceutical development and manufacturing services in the pharmaceutical and biotechnology space, a position she has held since 2020. Prior to joining August Bioservices, she served as SVP & president of AmerisourceBergen’s Clinical Product Solutions Business Unit. Amerisource Bergen is a United States-based pharmaceutical wholesale distributor. Ms. Adams spent her early career at Baxter Healthcare, serving in leadership roles in the Medication Delivery and Fenwal businesses.

Ms. Adams serves on the nonprofit Board of LifeScience Tennessee and holds an MBA from Northwestern University’s J.L. Kellogg Graduate School of Management.
We believe that Ms. Adams’ significant experience as an executive in several life science companies brings relevant expertise to the board of directors.
Charles J. Casamento has served as a member of our board of directors since 2017. Mr. Casamento is currently executive director and principal of The Sage Group, a healthcare advisory group specializing in mergers, acquisitions, and partnerships between biotechnology companies and pharmaceutical companies, since 2007.

We believe that Mr. Casamento’s significant experience as chief executive officer in various life sciences companies and his service on several other boards bring valuable knowledge and insights to the board of directors.
RECOMMENDATION: THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE “FOR” THE ELECTION OF THE NOMINEES NAMED ABOVE.

Code of Business Conduct and Ethics
We are committed to the highest standards of integrity and ethics in the way we conduct our business. In 2017, our board of directors adopted a Code of Business Conduct and Ethics, which applies to our directors, officers and employees, including our chief executive officer, our chief financial officer, and our other executive and senior officers. Our Code of Business Conduct and Ethics establishes our policies and expectations with respect to a wide range of business conduct, including the preparation and maintenance of our financial and accounting information, our compliance with laws, and possible conflicts of interest.
Under our Code of Business Conduct and Ethics, each of our directors and employees is required to report suspected or actual violations to the extent permitted by law. In addition, we have adopted separate procedures concerning the receipt and investigations of complaints relating to accounting or audit matters. These procedures have been adopted by the board of directors and are administered by our audit committee.
A current copy of our Code of Business Conduct and Ethics is posted on the Corporate Governance section of our website, which is located at www.etonpharma.com. If we make any substantive amendments to, or grant any waivers from, the Code of Business Conduct and Ethics for any officer or director, we will disclose the nature of such amendment or waiver on our website or in a Current Report on Form 8-K.
Independence of the Board of Directors
Consistent with our corporate governance guidelines and Nasdaq rules, our board of directors has determined that, as of the date of this Proxy Statement, all of the members of our board of directors other than Sean Brynjelsen, our president and chief executive officer, are “independent.” In addition, all members of the audit, compensation and nominating and corporate governance committees satisfy the applicable independence criteria of the SEC and Nasdaq.
For a stockholder communication directed to an individual director in his capacity as a member of the board of directors, stockholders may send such communication to the attention of the individual director via U.S. Mail or Expedited Delivery Service to: Eton Pharmaceuticals, Inc., 21925 W. Field Parkway, Suite 235, Deer Park, Illinois 60010.
We will forward by U.S. Mail any such stockholder communication to each director, and the Chair of the Board in his or her capacity as a representative of the board of directors, to whom such stockholder communication is addressed to the address specified by each such director and the Chair of the Board, unless there are safety or security concerns that mitigate against further transmission.
Board Leadership Structure and Board’s Role in Risk Oversight
Currently, the role of chairman of the board of directors is separated from the role of chief executive officer, and we plan to keep these roles separated. We believe that separating these positions allows our chief executive officer to focus on our day-to-day business, while allowing the chairman of the board to lead the board of directors in its fundamental role of providing advice to and independent oversight of management. Our board of directors recognizes the time, effort and energy that the chief executive officer is required to devote to his position in the current business environment, as well as the commitment required to serve as our chairman, particularly as the board of directors’ oversight responsibilities continue to grow. While our bylaws and corporate governance guidelines do not require that our chairman and chief executive officer positions be separate, our board of directors believes that having separate positions is the appropriate leadership structure for us at this time and demonstrates our commitment to good corporate governance.
Risk is inherent with every business, and how well a business manages risk can ultimately determine its success. We face a number of risks, including risks relating to our financial condition, development and commercialization activities, operations, strategic direction and intellectual property as more fully discussed under “Risk Factors” in our Annual Report on Form 10-K. Management is responsible for the day-to-day management of risks we face, while our board of directors, as a whole and through its committees, has responsibility for the oversight of risk management. In its risk oversight role, our board of directors has the responsibility to satisfy itself with the risk management processes designed and implemented by management are adequate and functioning as designed.
Our board of directors oversees the management of risks inherent in the operation of our business and the implementation of our business strategies. Our board of directors performs this oversight role by using several different levels of review. In connection with its reviews of the operations and corporate functions of our Company, our board of directors addresses the primary risks associated with those operations and corporate functions. In addition, our board of directors reviews the risks associated with our Company’s business strategies periodically throughout the year as part of its consideration of undertaking any such business strategies.
Each of our board committees also oversees the management of our Company’s risk that falls within the committee’s areas of responsibility. In performing this function, each committee has full access to management, as well as the ability to engage advisors. Our chief financial officer provides reports to the audit committee and is responsible for identifying, evaluating and implementing risk management controls and methodologies to address any identified risks. In connection with its risk management role, our audit committee meets privately with representatives from our independent registered public accounting firm and our chief financial officer. The audit committee oversees the operation of our risk management program, including the identification of the primary risks associated with our business and periodic updates to such risks, and reports to our board of directors regarding these activities.
Commitment to Environmental, Social and Governance Issues of Interest
Our board of directors and its committees are committed to alignment with environmental, social and governance (“ESG”) best practices in our industry while also taking into account the Company’s resources. The Company’s primary focus, however, is on achieving consistent profitability, and accordingly the Company is balancing the resources it needs to achieve its primary goal with the resources needed to implement ESG best practices. In future filings, we will continue to report on our progress on ESG practices.
Meetings of the Board of Directors
Our board of directors held ten regular meetings in 2025. During their respective terms of service, each director attended at least 90% of all meetings of the board of directors and the committees on which they then served that were held during 2025. Under our corporate governance guidelines, directors are expected to be active and engaged in discharging their duties and to keep themselves informed about our business and operations. Directors are also expected to attend all meetings of the board of directors and all meetings of the committees on which they serve. The Company does not have a policy on directors attending the annual meeting of stockholders, and no directors attended the 2025 Annual Meeting of Stockholders.
Board Committees
Our board of directors has three standing committees: an audit committee, a compensation committee and a nominating and corporate governance committee, each of which has the composition and responsibilities described below. The audit committee, compensation committee and nominating and corporate governance committee all operate under charters reviewed annually by the respective committees and approved by our board of directors (copies of which can be found on our website by visiting www.etonpharma.com and under “Corporate Governance”).
Audit Committee
Paul Maier, Charles Casamento, Norbert G. Riedel and Jenn Adams serve on the audit committee, which is chaired by Mr. Maier. The audit committee held five meetings in 2025. Our board of directors has determined that each of these individuals meets the independence requirements of the Sarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act, Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the applicable listing standards of Nasdaq. Each member of our audit committee can read and understand fundamental financial statements in accordance with Nasdaq audit committee requirements. In arriving at this determination, the board has examined each audit committee member’s scope of experience and the nature of their prior and/or current employment. Our board of directors has designated Mr. Maier as an “audit committee financial expert,” as defined under the applicable rules of the SEC. In making this determination, our board has considered Mr. Maier’s formal education and previous and current experience in financial and accounting roles. Both our independent registered public accounting firm and management periodically meet privately with our audit committee. The duties and responsibilities of the audit committee are set forth in the charter of the audit committee which was recently reviewed by our audit committee. Our audit committee determined that no revisions needed to be made to the charter at this time. A copy of the charter of the audit committee is available on our website, located at www.etonpharma.com, under the Investors – Corporate Governance – Governance Documents section. Among other matters, the duties and responsibilities of the audit committee include:

Compensation Committee
Charles Casamento, Paul Maier, Norbert G. Riedel and Jenn Adams serve on our compensation committee, which is chaired by Mr. Casamento. The compensation committee met once in 2025. These individuals are non-employee directors, as defined in Rule 16b-3 promulgated under the Exchange Act, and are “outside directors,” as defined pursuant to Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”). Our board of directors has determined that all of these individuals are “independent” as defined under the applicable listing standards of Nasdaq, including the standards specific to members of a compensation committee. The compensation committee meets with management periodically. The duties and responsibilities of the compensation committee are set forth in its charter. Our compensation committee determined that no revisions needed to be made to the charter at this time. A copy of the charter of the compensation committee is available on the Company’s website, located at www.etonpharma.com, under the Investors – Corporate Governance – Governance Documents section. As discussed in its charter, among other things, the duties and responsibilities of the compensation committee include:
|
● |
annually reviewing and recommending to the board of directors the corporate goals and objectives relevant to the compensation of our Chief Executive Officer; |
|
|
|
||
|
● |
evaluating the performance of our chief executive officer in light of such corporate goals and objectives and based on such evaluation (i) reviewing and determining the cash compensation of our chief executive officer and (ii) reviewing and approving grants and awards to our chief executive officer under equity-based plans; |
|
|
|
||
|
● |
reviewing and approving the cash compensation of our other executive officers; |
|
|
|
||
|
● |
reviewing and establishing our overall management compensation, philosophy and policy; |
|
|
|
||
|
● |
overseeing and administering our compensation and similar plans; |
|
|
|
||
|
● |
evaluating and assessing potential and current compensation advisors in accordance with the independence standards identified in the applicable Nasdaq rules; |
|
|
|
||
|
● |
reviewing and approving our policies and procedures for the grant of equity-based awards; |
|
|

● |

|
|
|
||
|
● |
preparing our compensation committee report, if and when required by SEC rules; |
|
|
|
||
|
● |
reviewing and discussing annually with management our “Compensation Discussion and Analysis”, if and when required by SEC rules, to be included in our annual proxy statement; and |
|
|
|
||
|
● |
reviewing and approving the retention or termination of any consulting firm or outside advisor to assist in the evaluation of compensation matters. |
In establishing and reviewing our compensation philosophy and programs, the compensation committee considers whether such programs encourage unnecessary or excessive risk taking. We believe that our executive compensation program does not encourage excessive or unnecessary risk taking. This is primarily due to the fact that our compensation programs are designed to encourage our executive officers and other employees to remain focused on both short-term and long-term strategic goals. As a result, we do not believe that our compensation programs are reasonably likely to have a material adverse effect on us.
Nominating and Corporate Governance Committee
Norbert G. Riedel, Charles Casamento, Paul Maier and Jenn Adams serve on our nominating and corporate governance committee, which is chaired by Dr. Riedel. The nominating and corporate governance committee met once in 2025. Our board of directors has determined that each member of the nominating and corporate governance committee is “independent” as defined in the applicable SEC and Nasdaq rules. The nominating and corporate governance committee meets periodically with management. The duties and responsibilities of the nominating and corporate governance committee are set forth in its charter. Our nominating and corporate governance committee determined that no revisions needed to be made to the charter at this time. A copy of the charter of the nominating and corporate governance committee is available on the Company’s website, located at www.etonpharma.com, under the Investors – Corporate Governance – Governance Documents section. As discussed in its charter, among other things, the duties and responsibilities of the nominating and corporate governance committee include:
|
● |
developing and recommending to the board of directors criteria for board and committee membership; |
|
|
|
||
|
● |
establishing procedures for identifying and evaluating board of director candidates, including nominees recommended by stockholders; |
|
|
|
||
|
● |
reviewing the composition of the board of directors to ensure that it is composed of members containing the appropriate skills and expertise to advise us; |
|
|
|
||
|
● |
identifying individuals qualified to become members of the board of directors; |
|
|
|
||
|
● |
recommending to the board of directors the persons to be nominated for election as directors and to each of the board’s committees; |
|
|
|
||
|
● |
developing and recommending to the board of directors a code of business conduct and ethics and a set of corporate governance guidelines; and |
|
|
|
||
|
● |
overseeing the evaluation of our board of directors and management. |
The board of directors is responsible for selecting its own members. The board of directors delegates the selection and nomination process to the nominating and corporate governance committee, with the expectation that other members of the board of directors, and management, will be requested to take part in the process as appropriate.
Each nominee is required to meet criteria established by the board of directors including possessing high standards of personal and professional ethics and integrity, proven achievement and competence in the nominee’s field and the ability to exercise sound business judgment. The committee may also take into account the then-current needs of the board of directors to maintain a balance of knowledge, expertise and capability. The nominating and corporate governance committee also recommends candidates to the board of directors for appointment to the committees of the board of directors. Once appropriate candidates have been identified, the entire board of directors votes on the candidates for appointment to the respective committees.
Generally, the nominating and corporate governance committee identifies candidates for director nominees in consultation with management, through the use of search firms or other advisors, through the recommendations submitted by stockholders or through such other methods as the nominating and corporate governance committee deems to be helpful to identify candidates. Once candidates have been identified, the nominating and corporate governance committee confirms that the candidates meet all of the minimum qualifications for director nominees established by the nominating and corporate governance committee. The nominating and corporate governance committee may gather information about the candidates in connection with its evaluation of a director candidate, including through candidate interviews, inquiry of the person or persons making the recommendation or nomination, engagement of an outside search firm, or reliance on the knowledge of the members of the nominating and corporate governance committee, the board of directors or management. The nominating and corporate governance committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of the board of directors. Based on the results of the evaluation process, the nominating and corporate governance committee recommends candidates for the board of directors’ approval as director nominees for election to the board of directors.
In evaluating proposed director candidates, the nominating and corporate governance committee will consider, in addition to the minimum qualifications and other criteria for board of directors membership approved by the board of directors from time to time, the current size and composition of the Board and the needs of the board of directors and the respective committees of the board of directors, such factors as character, integrity, judgment, diversity, independence, skills, education, expertise, business acumen, business experience, length of service, understanding of the Company’s business and industry, other commitments and the like and any other factors that the nominating and corporate governance committee may consider appropriate.
Stockholders may also submit recommendations for director candidates to the nominating and corporate governance committee by sending the individual’s name and qualifications to Eton Pharmaceuticals, Inc., 21925 W. Field Parkway, Suite 235, Deer Park, Illinois 60010, Attn: Corporate Secretary, who will forward all recommendations to the nominating and corporate governance committee. The nominating and corporate governance committee will evaluate any candidates recommended by stockholders against the same criteria and pursuant to the same policies and procedures applicable to the evaluation of candidates proposed by directors or management.
Policy on Trading, Pledging and Hedging of Company Stock
Certain transactions in our securities (such as purchases and sales of publicly traded put and call options and short sales) create a heightened compliance risk or could create the appearance of misalignment between management and stockholders. In addition, securities held in a margin account or pledged as collateral may be sold without consent if the owner fails to meet a margin call or defaults on the loan, thus creating the risk that a sale may occur at a time when an officer or director is aware of material, non-public information or otherwise is not permitted to trade in Company securities. Our insider trading policy expressly prohibits short sales and, without prior approval, derivative transactions of our stock by our executive officers, directors and specified other employees and their respective affiliates, purchases or sales of puts, calls or other derivative securities of the Company or any derivative securities that provide the economic equivalent of ownership of any of our securities or an opportunity, direct or indirect, to profit from any change in the value of our securities, or other hedging transactions. In addition, our insider trading policy expressly prohibits our executive officers, directors and specified other employees and their respective affiliates from borrowing against Company securities held in a margin account, or, without prior approval, pledging our securities as collateral for a loan.
Equity Grant Timing
During 2025, the Company did not issue any stock options to our named executive officers during the period beginning four business days before and ending one business day after (i) the filing of the Company’s Annual Report on Form 10-K, (ii) the filing of any of the Company’s Quarterly Reports on Form 10-Q, or (iii) the filing or furnishing of a Current Report on Form 8-K disclosing material nonpublic information.

Compensation Overview
This compensation overview, which should be read together with the compensation tables set forth below, provides information regarding our executive compensation program for our named executive officers for 2025, who are Sean E. Brynjelsen, our president and chief executive officer, James R. Gruber, our chief financial officer, David C. Krempa, our chief business officer, and Ipek Erdogan-Trinkaus, our chief commercial officer. During fiscal 2025, we did not have any other executive officers within the meaning of applicable SEC rules. We refer to these executive officers as our named executive officers.
Setting Executive Compensation
Our board of directors and compensation committee review executive compensation annually. In setting executive base salaries and bonuses and granting equity incentive awards, we consider compensation for comparable positions in the market, the historical compensation levels of our executives, individual performance as compared to our expectations and objectives, our desire to motivate our employees to achieve short- and long-term results that are in the best interests of our stockholders, and a long-term commitment to our company.
Our board of directors has historically determined our executives’ compensation. Our compensation committee typically reviews and discusses management’s proposed compensation with the chief executive officer for all executives other than the chief executive officer. Based on those discussions and its discretion, the compensation committee then recommends the compensation for each executive officer. Our board of directors, without members of management present, discusses the compensation committee’s recommendations and ultimately approves the compensation of our executive officers. Our board of directors reviewed the biennial compensation study report on director and officer compensation from Radford, an Aon company, who serves as our compensation consultant.
We have not adopted any formal guidelines for allocating total compensation between long-term and short-term compensation, cash compensation and non-cash compensation, or among different forms of non-cash compensation.
Role of the Compensation Committee
The compensation committee, which consists entirely of independent directors, reviews the compensation packages for our named executive officers, including an analysis of all elements of compensation separately and in the aggregate.
In reviewing and approving these matters, our compensation committee considers such matters as it deems appropriate, including our financial and operating performance, the alignment of the interests of our executive officers and our stockholders and our ability to attract and retain qualified and committed individuals, as well as the executive’s performance, experience, responsibilities and the compensation of executive officers in similar positions at comparable companies.
Role of Management
Our chief executive officer assists the compensation committee in identifying the key performance and incentive measures that may be used in setting annual cash performance bonus opportunities and also provides input on key contributors and performers within the Company so as to ensure their compensation accurately reflects their responsibilities, performance, experience levels and expected future contributions. Although our chief executive officer does not participate in decisions involving his own compensation, his recommendations and input, along with input from other executive officers, are often taken into consideration by the compensation committee when making compensation decisions.
Elements of Compensation
Base salary
Our compensation committee or the board of directors reviews the base salaries of our executive officers, including our named executive officers, from time to time and makes adjustments as it determines to be reasonable and necessary to reflect the scope of an executive officer’s performance, contributions, responsibilities, experience, prior salary level, position (in the case of a promotion) and market conditions.
Annual performance bonuses
We also believe that a significant portion of our executives’ cash compensation should be based on the attainment of business goals established by our board of directors or the compensation committee. The Company set target performance bonus amounts for 2025 for our executive officers pursuant to which officers would be paid a specified percentage of those targets based on operational results.
Specific achievements and performance metrics considered in 2025 included:
|
● |
Company stock performance relative to its peer group of companies; |
|
|
|
||
|
● |
Financial revenue and profitability for the year; |
|
|
|
||
|
● |
U.S. Food and Drug Administration (“FDA”) product approvals received; and |
|
|
|
||
|
● |
Product candidate licensing/acquisitions activity |
Based on the achievement of the above factors, the Company awarded each of our executive officers 83.0% of the target bonuses as listed in the Compensation Table.
Equity-based compensation
Equity-based compensation is an integral part of our overall compensation program. Providing named executive officers with the opportunity to create significant wealth through stock ownership is a powerful tool to attract and retain highly qualified executives, achieve strong long-term stock price performance, align our executives’ interests with those of our stockholders and provide a means to build real ownership in the Company.
We account for stock-based compensation under the provisions of the Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification (“ASC”) – 718 Compensation – Stock Compensation. The guidance under ASC 718 requires companies to estimate the fair value of the stock-based compensation awards on the date of grant for employees and directors and record expense over the related service periods, which are generally the vesting period of the equity awards.
We estimate the fair value of stock-based option awards to our employees and directors using the Black-Scholes Model (the “BSM”). The BSM requires the input of subjective assumptions, including the expected stock price volatility, the calculation of expected term, forfeitures and the fair value of the underlying common stock on the date of grant, among other inputs. The risk-free interest rate was determined from the implied yields for zero-coupon U.S. government issues with a remaining term approximating the expected life of the options. Dividends on common stock are assumed to be zero for the BSM valuation of the stock options. The expected term of stock options granted is based on vesting periods and the contractual life of the options. Expected volatilities are based on comparable companies’ historical volatility along with limited weighting for the Company’s own volatility, which management believes represents the most accurate basis for estimating expected future volatility under the current conditions. We account for forfeitures as they occur.
401(k) Plan
The Company established an employee savings plan pursuant to Section 401(k) of the Code, effective January 1, 2018. The plan allows participating employees to deposit into tax deferred investment accounts up to 100% of their salary, subject to annual limits. The Company makes certain matching contributions to the plan in amounts up to 5% of the participants’ annual cash compensation, subject to annual limits. Company contributions for the fiscal year ended December 31, 2025 were $349,813.
Health and Welfare Benefits
All of our full-time employees, including our executive officers are eligible to participate in certain medical benefit programs offered by us. We do not sponsor any qualified or non-qualified defined benefit plans for any of our employees or executives.

Compensation Committee Interlocks and Insider Participation
None of our independent directors is currently or has been at any time one of our officers or employees. None of our executive officers currently serves, or has served during the last year, as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of our board of directors.
PAY VERSUS PERFORMANCE
The following table shows the past three fiscal years’ total compensation for our named executive officers as set forth in the Summary Compensation Table, the “compensation actually paid” to our named executive officers (as determined under SEC rules), and our net income.
SEC rules require certain adjustments be made to the Summary Compensation Table totals to determine Compensation Actually Paid as reported in the Pay Versus Performance Table. Compensation Actually Paid does not necessarily represent cash and/or equity value transferred to the applicable named executive officer without restriction, but rather is a valuation calculated under applicable SEC rules. In general, Compensation Actually Paid is calculated as summary compensation table total compensation adjusted to (a) include the value of any pension benefit (or loss) attributed to the past fiscal year, including on account of any amendments adopted during such year; and (b) include the fair market value of equity awards as of December 31, 2025 or, if earlier, the vesting date (rather than the grant date) and factor in dividends and interest accrued with respect to such awards, if applicable. For purposes of the disclosure below, no pension valuation adjustments were required.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT
The following table sets forth certain information known to us regarding the beneficial ownership of our common stock as of April 10, 2026 for:
|
● |
each person known by us to be the beneficial owner of more than 5% of our common stock; |
|
|
● |
our named executive officers; |
|
|
● |
each of our directors and director nominees; and |
|
|
● |
all executive officers and directors as a group. |
Beneficial ownership is determined in accordance with the rules of the SEC and generally includes voting or investment power with respect to securities. Except as noted by footnote, and subject to community property laws where applicable, we believe, based on the information provided to us, that the persons and entities named in the table below have sole voting and investment power with respect to all shares of common stock shown as beneficially owned by them.
The beneficial ownership of each person was calculated based on 27,359,791 shares of common stock issued and outstanding as of April 10, 2026. The SEC has defined “beneficial ownership” to mean more than ownership in the usual sense. For example, a person has beneficial ownership of a share not only if he owns it, but also if he has the power (solely or shared) to vote, sell or otherwise dispose of the share. Beneficial ownership also includes the number of shares that a person has the right to acquire within 60 days pursuant to the exercise of options or warrants or the conversion of notes, debentures or other indebtedness. Accordingly, two or more persons might count as beneficial owners of the same share.

Excludes 9,147 stock option shares and 7,757 restricted stock units which vest after June 10, 2025. |
Section 16(a) Beneficial Ownership Reporting Compliance
Section 16(a) of the Exchange Act requires our directors and executive officers and persons who own more than 10% of our common stock, to file with the SEC initial reports of beneficial ownership and reports of changes in beneficial ownership. Officers, directors and greater than 10% stockholders are required by SEC regulations to furnish us with copies of all such reports.
To our knowledge, based solely on a review of the copies of such reports furnished to us and written representations that no other reports were required, we believe that for 2025, all directors and executive officers complied with filing reports required by Section 16(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).
Certain Relationships and Transactions with Related Parties
Our Chief Executive Officer has a partial interest in a company that the Company has entered into an agreement with as described below.
The Company acquired DS-200 and all related intellectual property pursuant to an asset purchase agreement (the “Selenix Agreement”) dated June 23, 2017 between the Company and Selenix LLC (“Selenix”), an entity affiliated with our Chief Executive Officer. On August 30, 2024, the Company amended the Selenix Agreement in tandem with an agreement to sell DS-200 in August 2024. Pursuant to the terms of the amended Selenix Agreement, Selenix waived its rights to future milestone payments and 50% of DS-200 profit in exchange for 45% of proceeds received by the Company from the DS-200 sale agreement. Selenix is 50% owned by Messa Holdings LLC (“Messa”), which is 100% owned by our Chief Executive Officer. The Company paid $220,000 to Selenix in October 2024 and $675,000 in June 2025.
Other Arrangements
Skye Cooper, the daughter of our Chief Executive Officer, Sean Brynjelsen, is employed by us and received $238,180 in total compensation in 2025.
Indemnification Agreements
We have entered into agreements to indemnify our directors and executive officers. These agreements will, among other things, require us to indemnify these individuals for certain expenses (including attorneys’ fees), judgments, fines and settlement amounts reasonably incurred by such person in any action or proceeding, including any action by or in our right, on account of any services undertaken by such person on behalf of our company or that person’s status as a member of our board of directors to the maximum extent allowed under Delaware law.
Policies for Approval of Related-Party Transactions
Our board of directors has adopted a written related party transactions policy that such transactions must be approved by our audit committee. Pursuant to this policy, the audit committee has the primary responsibility for reviewing and approving or disapproving “related party transactions,” which are transactions between us and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or will have a direct or indirect material interest. For purposes of this policy, a related person is defined as a director, executive officer, nominee for director, or greater than 5% beneficial owner of our common stock, in each case since the beginning of the most recently completed year, and their immediate family members.
PROPOSAL TWO - RATIFICATION OF THE APPOINTMENT OF OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
The audit committee has appointed Grant Thornton LLP as our independent registered public accounting firm to perform the audit of our consolidated financial statements for the fiscal year ending December 31, 2026. The Company is asking our stockholders to ratify the audit committee’s selection of Grant Thornton LLP as our independent auditors for the 2026 fiscal year.
The audit committee annually reviews the independent registered public accounting firm’s independence, including reviewing all relationships between the independent registered public accounting firm and our Company and any disclosed relationships or services that may impact the objectivity and independence of our independent registered public accounting firm, and the independent registered public accounting firm’s performance. As a matter of good corporate governance, the board of directors determined to submit to stockholders for ratification the appointment of Grant Thornton LLP. A majority of the votes represented at a meeting at which a quorum is present properly cast is required in order to ratify the appointment of Grant Thornton LLP. In the event that a majority of the votes properly cast do not ratify this appointment of Grant Thornton LLP, the audit committee will consider this factor when making any determinations regarding Grant Thornton LLP.
We expect that a representative of Grant Thornton LLP will attend the Annual Meeting telephonically and the representative will have an opportunity to make a statement if they so choose. The representative will also be available to respond to appropriate questions from stockholders.
Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm.
We have adopted a policy under which the audit committee is directly responsible for pre-approving all audit and permissible non-audit services to be provided by the independent registered public accounting firm. These services may include audit services, audit-related services, tax services and other services.
In addition, in the event time constraints require pre-approval prior to the audit committee’s next scheduled meeting, the audit committee has authorized its chairman to pre-approve services. Engagements so pre-approved are to be reported to the audit committee at its next scheduled meeting.

The audit committee currently consists of the four directors whose names appear below. None of the members of the audit committee is an officer or employee of the Company, and the Board has determined that each member of the audit committee is “independent” for audit committee purposes as that term is defined under Rule 10A-3 of the Exchange Act, and the applicable rules of the Nasdaq Stock Market LLC (“Nasdaq”). Each member of the audit committee meets the requirements for financial literacy under the applicable rules and regulations of the SEC and Nasdaq.

The audit committee has reviewed the Company’s financial statements for 2025 and met with management, as well as with representatives of, the Company’s independent registered public accounting firm, to discuss the consolidated financial statements. The audit committee also discussed with members of Grant Thornton LLP the matters required to be discussed by the Auditing Standard No. 1301, “Communication with Audit Committees,” as adopted by the Public Company Accounting Oversight Board.
In addition, the audit committee received the written disclosures and the letter from Grant Thornton LLP required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the audit committee concerning independence and discussed with members of Crowe LLP its independence.
Based on these discussions, the financial statement review and other matters it deemed relevant, the audit committee recommended to the Board that the Company’s audited consolidated financial statements for 2025 be included in its Annual Report on Form 10-K for 2025.
The information contained in this audit committee report shall not be deemed to be “soliciting material,” “filed” or incorporated by reference into any past or future filing under the Securities Exchange Act of 1934 or the Securities Act of 1933 unless and only to the extent that the Company specifically incorporates it by reference.
