QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING

​

Who is soliciting my vote?

The Board of Directors (the “Board”) of Helius Medical Technologies, Inc. (the “Company”, “we” or “us”) is soliciting your proxy, as a holder of our Class A common stock (the “Common Stock”), for use at the 2025 Annual Meeting of Stockholders to be held on Monday, April 21, 2025, at 9:00 a.m. Eastern Time, virtually at www.virtualshareholdermeeting.com/HSDT2025 and any adjournment or postponement of such meeting (the “Annual Meeting”).

The Notice of Annual Meeting of Stockholders, proxy statement and form of proxy card are expected to be first mailed to stockholders of record on or about March 25, 2025.

What is the purpose of the Annual Meeting?

At the Annual Meeting, you will be voting on:

The Board unanimously recommends that you vote FOR the election of each director nominee and FOR Proposals 2, 3, 4 and 5.

What if another matter is properly brought before the Annual Meeting?

The Board knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the Annual Meeting, it is the intention of the persons named in the accompanying form of proxy to vote on those matters in accordance with their best judgment.

Who is entitled to vote?

You may vote if you owned shares of our Common Stock at the close of business on March 12, 2025, the record date, provided such shares are held directly in your name as the stockholder of record or are held for you as the beneficial owner through a broker, bank or other nominee. As of March 12, 2025, we had 6,126,778 shares of Common Stock outstanding (excluding 2,678,000 shares of Common Stock held in abeyance for future issuance) and entitled to vote.

Holders of record of our Common Stock as of the close of business on the record date will be entitled to notice of and to vote at the Annual Meeting and at any adjournments or postponements thereof. Holders of record of shares of Common Stock have the right to vote on all matters brought before the Annual Meeting.

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

Stockholders of Record. If your shares of Common Stock are registered directly in your name with our transfer agent, Equiniti Trust Company, LLC, you are considered the stockholder of record with respect to those shares, and these proxy materials are being sent directly to you by us.

Beneficial Owners. Many of our stockholders hold their shares of Common Stock through a broker, bank or other nominee rather than directly in their own names. If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner with respect to those shares, and these proxy materials (including a voting instruction card) are being forwarded to you by your broker, bank or nominee who is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, bank or nominee on how to vote and are also invited to attend the Annual Meeting.

Can I vote my shares without attending the Annual Meeting?

Stockholders of Record. You may vote by internet, by phone or by completing, signing and returning the enclosed proxy card in the postage-paid envelope provided. To vote by internet or phone, you will need to use a control number provided to you in the materials with this proxy statement and follow the additional steps when prompted. The steps have been designed to authenticate your identity, allow you to give voting instructions, and confirm that those instructions have been recorded properly.

Beneficial Owners. If you are a beneficial owner, you must vote your shares in the manner prescribed by your broker, bank or other nominee. You will receive a voting instruction card (not a proxy card) to use in directing the broker, bank or other nominee how to vote your shares. You may also have the option to vote your shares via the internet or phone.

May I attend the Annual Meeting and vote my shares virtually?

The Annual Meeting will be held entirely online. To participate in the Annual Meeting, you will need the 16-digit control number included on the instructions that accompanied your proxy materials. We encourage you to access the meeting prior to the start time. If your shares are held in street name and you did not receive a 16-digit control number, you may gain access to and vote at the Annual Meeting by logging into your bank or brokerage firm’s website and selecting the stockholder communications mailbox to access the meeting. The control number will automatically populate. If you lose your 16-digit control number, you may join the Annual Meeting as a “Guest,” but you will not be able to vote, ask questions or access the list of stockholders as of the record date.

Can I change my vote?

Stockholders of Record. You may change your vote at any time before your proxy is exercised by sending a written notice of revocation or a later-dated proxy to our Secretary, which must be received prior to commencement of the Annual Meeting; by submitting a later-dated proxy via internet or phone; or by voting in person at the Annual Meeting. Internet voting facilities for stockholders of record will be available 24 hours a day beginning immediately and will close at 11:59 p.m. Eastern Time on April 20, 2025. Your virtual attendance at the Annual Meeting will not cause your previously granted proxy to be revoked unless you electronically vote at the Annual Meeting or file the proper documentation for it to be so revoked.

Beneficial Owners. If you hold your shares through a broker, bank or other nominee, you should contact such nominee prior to the time such voting instructions are exercised.

What does it mean if I receive more than one proxy card or voting instruction card?

If you receive more than one proxy card or voting instruction card, it means that you have multiple accounts with brokers, banks or other nominees and/or our transfer agent. Please sign and deliver, or otherwise vote, each proxy card and voting instruction card that you receive. We recommend that you contact your nominee and/or our transfer agent, as appropriate, to consolidate as many accounts as possible under the same name and address. Our transfer agent is Equiniti Trust Company, LLC, 6201 15th Avenue, Brooklyn, New York 11219; Telephone: 800-937-5449.

What if I do not vote for some of the items listed on my proxy or voting instruction card?

Stockholders of Record. If you indicate a choice with respect to any matter to be acted upon on your proxy card, the shares will be voted in accordance with your instructions. Shares represented by proxy cards that are signed and returned, but do not contain voting instructions with respect to certain matters, will be voted in the manner recommended by the Board on those matters and as the proxyholders may determine in their discretion for any other matters properly presented for a vote at the Annual Meeting.

Beneficial Owners. If you indicate a choice with respect to any matter to be acted upon on your voting instruction card, the shares will be voted in accordance with your instructions. If you do not indicate a choice or return the voting instruction card, the broker, bank or other nominee will determine if it has the discretionary authority to vote on each matter. Under applicable regulations, a broker, bank or nominee has the discretion to vote on routine matters, including Proposal 2, 3, 4 and 5. It is nonetheless very important for you to vote your shares for each proposal.

How many shares must be present to hold the meeting?

In order for us to conduct the Annual Meeting, holders of one-third of the voting power of our outstanding shares of stock entitled to vote as of March 12, 2025 must be present by remote communication or by proxy at the Annual Meeting. This is called a quorum. Abstentions (as well as broker non-votes, if any) will be considered present for purposes of determining a quorum. If a quorum is not reached, the Annual Meeting will be adjourned until a later time.

What vote is required to approve each item of business?

Proposal 1 - Election of Directors. Directors are elected by a plurality of the votes of the shares present by remote communication, or represented by proxy duly authorized at the Annual Meeting and entitled to vote generally on the election of directors. This means that the six individuals nominated for election to the Board at the Annual Meeting receiving the highest number of “FOR” votes will be elected. You may either vote “FOR” the nominee or “WITHHOLD” your vote with respect to the nominee. Broker non-votes and withhold votes, if any, will have no effect on the outcome of this proposal.

Proposal 2 – Ratification of Appointment of Auditors. The affirmative vote of the holders of a majority of the voting power of the shares present by remote communication or represented by proxy at the Annual Meeting and entitled to vote is required to approve the ratification of auditors. We do not anticipate receiving any broker non-votes on Proposal 2. Abstentions will have the same effect as a vote against the matter.

Proposal 3 – Approval of the Inducement Warrant Proposal. The affirmative vote of the holders of a majority of the voting power of the shares present by remote communication or represented by proxy at the Annual Meeting and entitled to vote is required to approve the Inducement Warrant Proposal. Broker non-votes, if any, will have no effect on the outcome of this proposal. Abstentions will have the same effect as a vote against the matter.

Proposal 4 – Approval of the Reverse Stock Split Proposal. The affirmative vote of the majority of the votes cast on this proposal is required for the approval of the Reverse Stock Split Certificate of Amendment to effect a reverse stock split. Abstentions and broker non-votes, if any, will have no effect on the outcome of this proposal.

​

Proposal 5 – Approval of Adjournment. The affirmative vote of the holders of a majority of the voting power of the shares of Common Stock present by remote communication or represented by proxy at the Annual Meeting and entitled to vote is required for any adjournment of the Annual Meeting to solicit additional proxies in the event there are insufficient votes to approve Proposals 3 or 4. Broker non-votes, if any, will have no effect on the outcome of this proposal. Abstentions will have the same effect as a vote against the matter.

Other Matters. The Board does not propose to conduct any business at the Annual Meeting, nor is it aware of any other matter to be presented for action at the Annual Meeting, other than as stated above.

Who will count the votes and where can I find the voting results?

Broadridge Financial Solutions, Inc. (“Broadridge”) will tabulate the voting results and a representative of American Election Services will act as inspector of election.

We intend to announce the preliminary voting results at the Annual Meeting and, in accordance with the rules of the Securities and Exchange Commission (the “SEC”), we intend to publish the final voting results in a current report on Form 8-K within four business days of the Annual Meeting.

​

PROPOSAL 1 – ELECTION OF DIRECTORS

General

Our Board currently consists of six directors, all of whom are being nominated for reelection at this Annual Meeting. The authorized number of directors may be changed from time to time by resolution of the Board. Each director to be elected and qualified will hold office until the next annual meeting of stockholders and until his or her successor is duly elected and qualified or until his or her earlier death, resignation or removal. All of the nominees listed below are currently directors of the Company who were previously elected by the stockholders. It is the Company’s policy to invite its nominees for directors to attend the Annual Meeting. Two of the directors attended the 2024 Annual Meeting of Stockholders. Proxies cannot be voted for a greater number of persons than the number of nominees named in this proposal.

Directors will be elected by a plurality of the votes of the shares present by remote communication, or represented by proxy duly authorized at the Annual Meeting and entitled to vote generally on the election of directors. Accordingly, the six nominees receiving the highest number of affirmative votes will be elected.

Nominees

The Company seeks to assemble a board that, as a whole, possesses the appropriate balance of professional and industry knowledge, financial expertise and high-level management experience necessary to oversee and direct the Company’s business. To that end, the Board has identified and evaluated nominees in the broader context of the Board’s overall composition, with the goal of recruiting members who complement and strengthen the skills of other members and who also exhibit integrity, collegiality, sound business judgment and other qualities that the Nominating and Corporate Governance Committee views as critical to effective functioning of the Board. The brief biographies below include information, as of the date of this proxy statement, regarding the specific and particular experience, qualifications, attributes or skills of each nominee that led the Board to believe that that nominee should serve on the Board. However, each of the members of the Board may have a variety of reasons why he or she believes a particular person would be an appropriate nominee for the Board, and these views may differ from the views of other members.

OUR BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” EACH DIRECTOR NOMINEE.

​

INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

Independence of the Board of Directors

The Board reviews its composition annually, including the determination of the independence of our directors. Our Board consults with the Company’s counsel to ensure that the Board’s determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent” set forth in pertinent listing standards of Nasdaq, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and the Company, its senior management and its independent auditors, the Board has affirmatively determined that all of the Company’s director nominees, other than Messrs. Andreeff and Mathiesen, are independent, as defined under the Nasdaq listing standards. In making those independence determinations, the Board took into account certain relationships and transactions that occurred in the ordinary course of business between the Company and entities with which some of its directors are or have been affiliated. The Board considered all relationships and transactions that occurred during any 12-month period within the last three fiscal years. The Board determined that the relationships would not interfere with their exercise of independent judgment in carrying out their responsibilities as directors.

Board Leadership Structure

The Board is currently chaired by Blane Walter, an independent member of the Board.

The Board does not have a formal policy with respect to the separation of the offices of Chief Executive Officer and Chair of the Board. It is the Board’s view that rather than having a formal policy, the Board, upon consideration of all relevant factors and circumstances, will determine, as and when appropriate, whether it is in the best interests of the Company and its stockholders for such offices to be separate or combined.

The Board currently believes that, by separating the positions of Chair of the Board and Chief Executive Officer, the Board can provide significant leadership to management and strong oversight of key opportunities and risks impacting the Company.

Role of the Board in Risk Oversight

The Board plays an active role in overseeing management of our risks. The Board regularly reviews information regarding our strategy, liquidity and operations, as well as the risks associated with each. The Audit Committee of the Board is responsible for overseeing the management of financial risks and cybersecurity risks. The Compensation Committee is responsible for overseeing the management of risks relating to our executive compensation policies and arrangements, and for managing risks relating to our director compensation policies and arrangements. Our Nominating and Corporate Governance Committee is responsible for reviewing the independence of the Board and other corporate governance matters.

Meetings of the Board of Directors

The Board met four times during 2024. Each current Board member who served as a director in 2024 attended 75% or more of the aggregate number of meetings of the Board and of the committees on which he or she served that were held during a portion of the last fiscal year.

Information Regarding Committees of the Board of Directors

The Board has three committees: an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. The following table provides current committee membership:

​

Below is a description of each committee of the Board of Directors. Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities.

Audit Committee

Our Audit Committee is comprised of Messrs. Buckman, Straw and Walter. Mr. Buckman is the chair of the Audit Committee. The Board has also determined that each of Mr. Buckman and Mr. Walter qualifies as an “audit committee financial expert,” as defined in applicable SEC rules. The Board made a qualitative assessment of Mr. Buckman’s and Mr. Walter’s level of knowledge and experience based on a number of factors.

The Audit Committee was established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), to oversee the Company’s corporate accounting and financial reporting processes and audits of its financial statements. For this purpose, the Audit Committee performs several functions including the following:

The Audit Committee met five times during 2024. The Board has adopted a written Audit Committee charter that is available to stockholders on the Company’s website at www.heliusmedical.com.

The Board reviews the definition of independence for Audit Committee members under SEC rules and Nasdaq listing standards on an annual basis and has determined that all members of the Company’s Audit Committee are independent for such purposes.

Report of the Audit Committee of the Board of Directors

The material in this report is not “soliciting material,” is not deemed “filed” with the SEC and is not to be incorporated by reference in any filing of the Company under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

Compensation Committee

Our Compensation Committee is comprised of Messrs. Buckman, Straw and Ms. Perkins. Mr. Straw is the chair of the Compensation Committee.

All members of the Company’s Compensation Committee are independent (as independence is currently defined in Rule 5605(d)(2) of the Nasdaq Listing Rules). The Compensation Committee met one time during 2024. The Board has adopted a written Compensation Committee charter that is available to stockholders on the Company’s website at www.heliusmedical.com.

The Compensation Committee acts on behalf of the Board to do the following:

Compensation Determination: Processes and Procedures

The Compensation Committee meets at least annually and with greater frequency if necessary and appropriate. The agenda for each meeting is developed by the Chair of the Compensation Committee, in consultation with legal counsel or other advisers or consultants

it deems necessary and appropriate. The Compensation Committee meets regularly in executive session. However, from time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of the Company. In addition, under the charter, the Compensation Committee has the authority to obtain, at the expense of the Company, advice and assistance from compensation consultants and internal and external legal, accounting or other advisors and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the Compensation Committee. In particular, the Compensation Committee has the sole authority to retain, in its sole discretion, compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under the charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the Compensation Committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and Nasdaq, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent.

In fiscal 2024 and fiscal 2023, the Compensation Committee delegated authority to the Chief Executive Officer to grant, without any further action required by the Compensation Committee, equity awards to employees and consultants who are not officers of the Company. The purpose of this delegation of authority is to enhance the flexibility of option administration within the Company and to facilitate the timely grant of options to non-management employees, within specified limits approved by the Compensation Committee.

Historically, the Compensation Committee has typically made any significant adjustments to annual compensation, determined bonus and equity awards and established new performance objectives at one or more meetings held during the first quarter of the year. Generally, the process consists of two related elements: the determination of compensation levels and the establishment of performance objectives for the current year. For executives other than the Chief Executive Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to the Committee by the Chief Executive Officer. In the case of the Chief Executive Officer, the evaluation of his performance is conducted by the Compensation Committee, which determines any adjustments to his compensation as well as awards to be granted. The Chief Executive Officer may not be present during these discussions. The Compensation Committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, tax and accounting information, tally sheets that set forth the total compensation that may become payable to executives in various hypothetical scenarios, executive and director stock ownership information, company stock performance data, analyses of historical executive compensation levels and current Company-wide compensation levels and recommendations of the Company’s compensation consultant, including analyses of executive and director compensation paid at other companies of comparable financial size and business focus.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee is currently comprised of Messrs. Buckman, Straw and Ms. Perkins. Ms. Perkins is the chair of the Nominating and Corporate Governance Committee.

All members of the Nominating and Corporate Governance Committee are independent (as independence is currently defined in Rule 5605(a)(2) of the Nasdaq Listing Rules). The Nominating and Corporate Governance Committee met one time during 2024. The Board has adopted a written Nominating and Corporate Governance Committee charter that is available to stockholders on the Company’s website at www.heliusmedical.com.

The Nominating and Corporate Governance Committee is responsible for the following:

Generally, director nominees are identified and suggested by our directors or management using their business networks. The Nominating and Corporate Governance Committee also intends to consider director nominees put forward by stockholders. Our Second Amended and Restated Bylaws (the “Bylaws”) contain provisions that address the process by which a stockholder may nominate an individual to stand for election to the Board at the annual meeting. Such nomination must satisfy the notice, information and consent requirements set forth in our Bylaws and must be received by us prior to the date set forth under “Additional Matters - Requirements for Submission of Stockholder Proposals and Nominations for 2026 Annual Meeting”.

Stockholders may also recommend individuals to our Board for consideration as potential director candidates by submitting the names of the recommended individuals, together with appropriate biographical information and background materials, to the Board at Helius Medical Technologies, Inc., 642 Newtown Yardley Road, Suite 100, Newtown, Pennsylvania 18940, Attention: Chairman of the Board. The Board does not intend to alter the manner in which it evaluates candidates, based on whether or not the candidate was recommended by a stockholder.

The Nominating and Corporate Governance Committee does not have any specific minimum qualifications that director nominees must have in order to be considered to serve on the Board. However, the Nominating and Corporate Governance Committee does take into consideration areas of expertise that director nominees may be able to offer, including professional experience, knowledge, abilities and industry knowledge or expertise. The Nominating and Corporate Governance Committee also considers their potential contribution to the overall composition of the Board.

The Nominating and Corporate Governance Committee will review the backgrounds and qualifications of any potential nominees, without regard to whether a potential nominee has been recommended by our stockholders, and, upon consideration of all relevant factors and circumstances, approves the slate of director nominees to be nominated for election at each annual meeting of stockholders.

The Nominating and Corporate Governance Committee seeks a Board that includes a diversity of perspectives and includes individuals that possess backgrounds, skills, expertise and attributes that allow them to function collaboratively and effectively together in their oversight of the Company.

Stockholder Communications With the Board of Directors

The Board welcomes communications from our stockholders and other interested parties. Stockholders and other interested parties may send communications to the Board, to any particular director or the independent directors as a group, to the following address: Helius Medical Technologies, Inc., 642 Newtown Yardley Road, Suite 100, Newtown, Pennsylvania 18940. Stockholders or interested parties should indicate clearly the director or directors to whom the communication is being sent so that each communication may be forwarded directly to the appropriate director(s).

Insider Trading Compliance Policy

Our Board has adopted an Insider Trading Compliance Policy governing the purchase, sale, and/or other dispositions by directors, officers, employees and other specified persons. This policy is designed to create reasonable processes to prevent the Company and its directors, officers, employees and specified other persons from insider trading and any appearance of improper conduct.

Our Insider Trading Compliance Policy is designed to promote compliance with insider trading laws. Our employees (including our named executive officers) and directors are subject to the Company’s Insider Trading Compliance Policy, which applies to their transactions involving any securities of the Company. Except under limited circumstances, persons subject to the policy, their affiliates and certain members of their family may not engage in any transaction of Company securities (or assist or encourage other persons to do so) while aware of material non-public information relating to the Company. The policy also implements quarterly trading blackout periods and pre-clearance requirements, and allows for special blackout periods, for our NEOs and other specified persons to reduce the likelihood of trading at times with significant risk of insider trading exposure.

Further, the policy includes Rule 10b5-1 trading plan guidelines to assist in compliance with the Rule 10b5-1 affirmative defense for insider trading liability, including that such plans can only be adopted or modified when the applicable person is permitted to transact in Company securities under the terms of the policy (including not being aware of any material non-public information), must include the minimum statutory cooling-off period between plan adoption and the first trade under such plan, and must comply with the prohibitions on multiple overlapping plans and limitations on single-trade plans. The adoption, modification or termination of any such plan is subject to pre-clearance requirements.

Our Insider Trading Policy also specifically prohibits, among other things, all directors and executive officers and employees of the Company from effecting hedging or monetization transactions, such as zero-cost collars and forward sale contracts. A copy of our Insider Trading Compliance Policy is filed as an exhibit to our Annual Report on Form 10-K for 2024.

Code of Business Conduct and Ethics

The Company has adopted a Code of Business Conduct and Ethics that applies to all officers, directors and employees. The Code of Business Conduct and Ethics is available on the Company’s website at www.heliusmedical.com. If the Company makes any substantive amendments to the Code of Business Conduct and Ethics or grants any waiver from a provision of the Code of Business Conduct and Ethics to any executive officer or director, the Company will promptly disclose the nature of the amendment or waiver on its website.

Policy for the Recovery of Erroneously Awarded Compensation

As required by the listing standards adopted by Nasdaq as a result of SEC rulemaking, our Board recently adopted a new Policy for the Recovery of Erroneously Awarded Compensation. The policy provides that the Company must promptly recover specified incentive-based compensation that is received by our Section 16 officers on or after October 2, 2023, regardless of fault or misconduct, upon specified accounting restatements of the Company’s financial statement that resulted in such persons receiving an amount that exceeded the amount that would have been received if based on the restated financial statements. There are limited exceptions to the recovery requirement as set forth in the listing standards. Incentive-based compensation is defined as any compensation that is granted, earned, or vested based wholly or in part upon the attainment of a financial reporting measure. The subject compensation will be determined without regard to any net settlement of, or taxes paid or payable or withheld on, such compensation, but there will not be any duplicative recovery by the Company. As specified in the listing standards, the Company cannot indemnify, or pay or reimburse for insurance for, a Section 16 officer for recoveries under this policy.

The recovery period under the policy is three full years preceding the date our Board or a committee thereof as directed by the Board concludes, or reasonably should have concluded, that an accounting restatement is required. If applicable, the Company will provide the current or former Section 16 officer with a written demand for repayment or return and the method thereof. If such repayment or return is not made when due, the policy provides that the Company will take all reasonable and appropriate actions to recover such erroneously awarded compensation from such person.

EXECUTIVE COMPENSATION

The following tables and accompanying narrative disclosure discuss the compensation awarded to, earned by, or paid to:

We refer to these three executive officers as the “named executive officers” (as determined pursuant to the SEC’s disclosure requirements for executive compensation in Item 402 of Regulation S-K).

Summary Compensation Table

The following table presents summary information regarding the total compensation for services rendered in all capacities that was earned by our named executive officers during the fiscal years ended December 31, 2024 and 2023.

Narrative Disclosure to Summary Compensation Table

The compensation program for the Company’s named executive officers for 2024 had three primary components: base salary, annual bonus and equity grants.

Annual Base Salary

We have entered into employment agreements with each of our named executive officers that establish annual base salaries, which are reviewed periodically by our Compensation Committee in order to compensate our named executive officers for the satisfactory performance of duties to the Company. Annual base salaries are intended to provide a fixed component of compensation to our named executive officers, reflecting their skill sets, experience, roles and responsibilities. Base salaries for our named executive officers have generally been set at levels deemed necessary to attract and retain individuals with superior talent. On February 20, 2024, our Board, upon recommendation of the Compensation Committee, in consultation with an independent compensation consultant, Grant Thornton LLP, approved a 4% increase to the base salaries of our executive officers for 2024 as an adjustment to account for cost of living increases.

Mr. Andreeff. Effective with his appointment as President and Chief Executive Officer on June 14, 2021, the Company entered into an employment agreement with Mr. Andreeff that provides for an annual base salary of $350,000 subject to annual review by the

Compensation Committee. As a result of our Compensation Committee’s decision to increase our executive officers’ salaries by 4% to account for increases in cost of living and following similar increases in prior years, Mr. Andreeff’s annual base salary for 2024 was $402,000.

Mr. Mathiesen. Effective with his appointment as Chief Financial Officer, Treasurer and Secretary on June 14, 2021, the Company entered into an employment agreement with Mr. Mathiesen that provides for an annual base salary of $335,000, subject to annual review by the Compensation Committee. As a result of our Compensation Committee’s decision to increase our executive officers’ salaries by 4% to account for increases in cost of living and following similar increases in prior years, Mr. Mathiesen’s annual base salary for 2024 was $385,000.

Dr. Favit-Van Pelt. Effective with her appointment as Chief Medical Officer on July 7, 2021, the Company entered into an employment agreement with Dr. Favit-Van Pelt that provides for an annual base salary of $340,000, subject to annual review by the Compensation Committee. As a result of our Compensation Committee’s decision to increase our executive officers’ salaries by 4% to account for increases in cost of living and following similar increases in prior years, Ms. Favit-Van Pelt’s annual base salary for 2024 was $390,000.

Non-Equity Incentive Plan

In 2024, each of the Company’s named executive officers had a target bonus, set forth as a percentage of annual base salary. Pursuant to the employment agreements between the Company and Messrs. Andreeff and Mathiesen, target bonuses for Messrs. Andreeff and Mathiesen were set at 50% and 40%, respectively, with the Compensation Committee able to determine that a portion of such target be paid in equity in lieu of cash. Under the employment agreement between the Company and Dr. Favit-Van Pelt, her target bonus was set at 35%.

In March 2024, the Compensation Committee recommended, and the Board approved, performance targets for fiscal 2024 that it would consider in approving bonus payments for 2024. These targets included various corporate objectives related to Company regulatory goals, revenue goals, financing goals, clinical research and development goals, and a goal related to the transition of the Company’s manufacturer.

In February 2025, the Compensation Committee determined that 83% of the performance targets had been met, and approved the bonus payments to Mr. Andreeff, Mr. Mathiesen, and Dr. Favit-Van Pelt at 83% of their respective targets.

Equity-Based Awards

On July 2, 2024, our Board, upon recommendation of the Compensation Committee, approved the grant of an option to purchase 808,000 shares of Common Stock to Mr. Andreeff, an option to purchase 404,000 shares of Common Stock to Mr. Mathiesen, and an option to purchase 277,000 shares of common stock to Ms. Favit-Van Pelt pursuant to the 2022 Plan. Each of these stock options has an exercise price equal to the fair market value of a share of Common Stock as of the grant date, as determined in accordance with our 2022 Plan. Each of stock options granted to Messrs. Andreeff and Mathiesen and Ms. Favit-Van Pelt, respectively, vested as to 62.5% immediately as of the grant date with the remainder vesting in a series of ten successive equal quarterly installments on the last day of each fiscal quarter beginning on September 30, 2024.

Retirement Benefits and Other Compensation

Our named executive officers do not participate in, or otherwise receive any benefits under, any pension or deferred compensation plan sponsored by us. We provide our employees a percentage match to the contributions made by our employees to the Company’s 401(k) savings plan and we provide life insurance benefits to our named executive officers. Our named executive officers were eligible to participate in our employee benefits, including health benefits, on the same basis as our other employees. We generally do not provide perquisites or personal benefits except in limited circumstances.

The following table sets forth certain information regarding the ownership of our Common Stock as of March 12, 2025 by: (i) each director; (ii) each of our named executive officers; (iii) all executive officers and directors of the Company as a group; and (iv) all those known by the Company to be beneficial owners of more than five percent of our Common Stock.

We have determined beneficial ownership in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, these rules require that we include shares of Common Stock issuable pursuant to the vesting of warrants and the exercise of stock options that are either immediately exercisable or exercisable within 60 days of March 12, 2025, and restricted stock units that vest within 60 days of March 12, 2025. These shares are deemed to be outstanding and beneficially owned by the person holding those warrants or options for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. This table is based on information supplied by officers, directors and principal stockholders and Schedule 13D, Schedule 13G and Section 16 filings, if any, with the SEC. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.

Except as otherwise noted below, the address for persons listed in the table is c/o Helius Medical Technologies, Inc., 642 Newtown Yardley Road, Suite 100, Newtown, Pennsylvania 18940. As of March 12, 2025, we had 6,126,778 shares of Common Stock outstanding (excluding 2,678,000 shares of Common Stock held in abeyance for future issuance).

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

​

Policies and Procedures for Transactions with Related Parties

In January 2018, the Company adopted a written Related-Person Transactions Policy that sets forth the Company’s policies and procedures regarding the identification, review, consideration and approval or ratification of “related-persons transactions.” For purposes of the Company’s policy only, a “related-person transaction” is a transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) in which the Company and any “related person” are participants involving an amount that exceeds $120,000. Transactions involving compensation for services provided to the Company as an employee, director, consultant or similar capacity by a related person are not covered by this policy. A related person is any executive officer, director, nominee to become director, or more than 5% stockholders of the Company, including any of their immediate family members, and any entity owned or controlled by such persons.

Under the policy, where a transaction has been identified as a related-person transaction, management must present information regarding the proposed related-person transaction to the Audit Committee (or, where Audit Committee approval would be inappropriate, to another independent body of the Board) for consideration and approval or ratification. The presentation must include a description of, among other things, the material facts, the interests, direct and indirect, of the related persons, the benefits to the Company of the transaction and whether any alternative transactions were available. To identify related-person transactions in advance, the Company relies on information supplied by its executive officers, directors and certain significant stockholders. In considering related-person transactions, the Audit Committee takes into account the relevant available facts and circumstances including, but not limited to (a) the risks, costs and benefits to the Company, (b) the impact on a director’s independence in the event the related person is a director, immediate family member of a director or an entity with which a director is affiliated, (c) the terms of the transaction, (d) the availability of other sources for comparable services or products and (e) the terms available to or from, as the case may be, unrelated third parties or to or from employees generally. In the event a director has an interest in the proposed transaction, the director must recuse himself or herself from the deliberations and approval. The policy requires that, in determining whether to approve, ratify or reject a related-person transaction, the Audit Committee consider, in light of known circumstances, whether the transaction is in, or is not inconsistent with, the best interests of the Company and its stockholders, as the Audit Committee determines in the good faith exercise of its discretion.

The Audit Committee and/or the independent directors of the Board review such proposed business transactions to ensure that the Company’s involvement in such transactions is on terms comparable to those that could be obtained in arm’s length dealings with an unrelated third party and is in the best interests of the Company and its stockholders.

Certain Relationships and Related Transactions

The following includes a summary of transactions since January 1, 2024 to which the Company has been a participant in which the amount involved exceeded or will exceed the lesser of $120,000 or 1% of the average of the Company’s total assets at year end for the last two completed fiscal years, and in which any of our directors, executive officers or holders of more than five percent of our capital stock, or any members of their immediate family, had or will have a direct or indirect material interest. Other than described below, there have not been, nor are there currently any proposed, transactions or series of similar transactions to which we have been or will be a party other than compensation arrangements, which include equity and other compensation, termination, change in control and other arrangements, which are described under “Executive Compensation.”

Indemnification Agreements

The Company provides indemnification for its directors and officers so that they will be free from undue concern about personal liability in connection with their service to the Company. Under the Bylaws, the Company is required to indemnify its directors and officers to the extent not prohibited under Delaware or other applicable law. The Company has also entered into indemnity agreements with its officers and directors. These agreements provide, among other things, that the Company will indemnify the officer or director, under the circumstances and to the extent provided for in the agreement, for expenses, damages, judgments, fines and settlements he or she may be required to pay in actions or proceedings which he or she is or may be made a party by reason of his or her position as a director, officer or other agent of the Company, and otherwise to the fullest extent permitted under applicable law and the Bylaws.

​

PROPOSAL 2 – RATIFICATION OF APPOINTMENT OF INDEPENDENT

REGISTERED PUBLIC ACCOUNTING FIRM

Baker Tilly US, LLP audited our financial statements as of and for the fiscal years ended December 31, 2023 and December 31, 2024. Representatives of Baker Tilly US, LLP are expected to be present at the Annual Meeting by remote communication. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

The Audit Committee has selected Baker Tilly US, LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2025, and the Board has further directed that management submit the selection of its independent registered public accounting firm for ratification by the stockholders at the Annual Meeting. Neither the Bylaws nor other governing documents or law require stockholder ratification of the selection of Baker Tilly US, LLP as the Company’s independent registered public accounting firm. However, the Audit Committee is submitting the selection of Baker Tilly US, LLP to our stockholders for ratification because we value our stockholders’ views on our independent registered public accounting firm and as a matter of good corporate governance. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain Baker Tilly US, LLP. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of different independent auditors at any time during the year if they determine that such a change would be in the best interests of the Company and its stockholders.

The affirmative vote of the holders of a majority of the voting power of the shares present by remote communication or represented by proxy at the Annual Meeting and entitled to vote is required to ratify the selection of Baker Tilly US, LLP.

Principal Accountant Fees and Services

The Audit Committee retained Baker Tilly US, LLP to audit the Company’s consolidated financial statements for the years ended December 31, 2024 and December 31, 2023. The following table represents aggregate fees billed to the Company for the fiscal years ended December 31, 2024 and December 31, 2023 (amounts in thousands).

All fees described above were pre-approved by the Audit Committee.

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

The Company’s Audit Committee has adopted policies and procedures for the pre-approval of audit services and permitted non-audit and tax services rendered by our independent registered public accounting firm. The policy generally provides pre-approval of specified services in the defined categories of audit services, audit-related services and tax services up to specified amounts. Pre-approval may also be given as part of the Audit Committee’s approval of the scope of the engagement of the independent auditor or on an individual, explicit, case-by-case basis before the independent auditor is engaged to provide each service. The Audit Committee must pre-approve all services provided by the independent registered public accounting firm.

The Audit Committee has determined that the rendering of services other than audit services by Baker Tilly US, LLP is compatible with maintaining the principal accountant’s independence.

OUR BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” APPROVAL OF

PROPOSAL 2.

​

PROPOSAL 3 – APPROVAL OF THE ISSUANCE OF SHARES OF
COMMON STOCK UPON EXERCISE OF THE INDUCEMENT WARRANTS

Overview

At the Annual Meeting, holders of our Common Stock will be asked to approve the issuance of up to 6,213,888 shares of our outstanding Common Stock (“Inducement Warrant Shares”) upon the exercise of our Series C warrants and Series D warrants (the “Inducement Warrants”), with the right for such potential exercise to occur immediately following the date upon which the stockholders approve this proposal, for purposes of compliance with Nasdaq Rule 5635(d) and as required by the Inducement Letters (as defined below) entered into with certain holders of our outstanding Series A warrants and Series B warrants (the “Existing Warrants”).

As a material condition of the warrant inducement described below, the Company agreed to submit and recommend this proposal to the stockholders. The Board believes that the terms of the Inducement Warrants and the exercise thereof and this proposal are in the best interests of the Company and its stockholders in order to fulfill and meet its contractual commitments made pursuant to the Inducement Letters. Under the Inducement Letters, we agreed to use our commercially reasonable efforts to hold a special meeting of stockholders on or before April 21, 2025 to obtain stockholder approval for the exercise of the Inducement Warrants, with the recommendation of the Board that such proposal be approved. We agreed that we would solicit proxies from our stockholders in connection with such proposal in the same manner as all other management proposals in the proxy statement and that all management-appointed proxyholders would vote their proxies in favor of such proposal. If we do not obtain stockholder approval of this proposal at the Annual Meeting, we have agreed to call a meeting of stockholders every 90 days thereafter to seek stockholder approval until stockholder approval is obtained (“stockholder approval”).

Description of the Inducement Offer

On January 21, 2025, the Company entered into warrant exercise inducement offer letters (the “Inducement Letters”) with certain holders (the “Inducement Warrant Holders”) of its Existing Warrants, pursuant to which the Inducement Warrant Holders agreed to exercise for cash their Existing Warrants to purchase an aggregate of 4,971,110 shares of the Company’s common stock, in the aggregate, at a reduced exercise price of $0.751 per share, in exchange for the Company’s agreement to the Inducement Warrants on substantially the same terms as the Existing Warrants described below, to purchase up to 6,213,888 shares of the Company’s common stock (the “Inducement Offer”). In accordance with the Inducement Letters, we shall only issue such number of shares of common stock issuable to holders that would not cause such holders to exceed the maximum number of shares permitted thereunder, with the balance of shares to be held in abeyance until notice from the applicable holder that the balance (or portion thereof) may be issued in compliance with the limitations set forth.  As of March 7, 2025, 2,678,000 unissued shares of Common Stock remained in abeyance from these warrant exercises.

The Company also agreed to file a registration statement on Form S-3 (or other appropriate form if the Company is not then Form S-3 eligible) covering the resale of the Inducement Warrants Shares issued or issuable upon the exercise of the Inducement Warrants  within ten (10) calendar days of the date of the Inducement Letters. In the Inducement Letters, the Company agreed not to issue any shares of common stock or common stock equivalents or to file any other registration statement with the SEC (in each case, subject to certain exceptions) for sixty (60) calendar days. The Company also has agreed not to effect or enter into any agreement to effect any variable rate transaction (as defined in the Inducement Letters) for seventy-five (75) calendar days from the date of the Inducement Letters.

Description of Inducement Warrants

Duration and Exercise Price

Each Inducement Warrant will have an exercise price equal to the Nasdaq Minimum Price (as defined in Nasdaq Listing Rule 5635(d)), which was $0.751 per share as of January 21, 2025. The Series C and Series D Warrants will only be exercisable contingent upon and after receiving stockholder approval and may be exercised until five years and two years from the date of such stockholder approval, respectively. The exercise price and number of shares of common stock issuable upon exercise is subject to appropriate adjustment in the event of stock dividends, stock splits, reorganizations or similar events affecting our common stock and the exercise price. The Inducement Warrants were issued in certificated form only.

Exercisability

The Inducement Warrants will be exercisable, at the option of each holder, in whole or in part, by delivering to us a duly executed exercise notice accompanied by payment in full for the number of shares of our common stock purchased upon such exercise. A holder (together with its affiliates) may not exercise any portion of such holder’s Series C Warrants and Series D Warrants to the extent that the holder would own more than 4.99% (and in some cases, 9.99%) of the outstanding common stock immediately after exercise.

Fundamental Transactions

In the event of any fundamental transaction, as described in the Inducement Warrants and generally including any merger with or into another entity, sale of all or substantially all of our assets, tender offer or exchange offer, or reclassification of our common stock, then upon any subsequent exercise of an Inducement Warrant, the holder will have the right to receive as alternative consideration, for each share of our common stock that would have been issuable upon such exercise immediately prior to the occurrence of such fundamental transaction, the number of shares of common stock of the successor or acquiring corporation or of the Company, if it is the surviving corporation, and any additional consideration receivable upon or as a result of such transaction by a holder of the number of shares of our common stock for which the Inducement Warrant is exercisable immediately prior to such event. Notwithstanding the foregoing, in the event of a fundamental transaction, the Inducement Warrant Holders have the right to require us or a successor entity to redeem the Inducement Warrants for cash in the amount of the Black Scholes Value (as defined in each Inducement Warrant) of the unexercised portion of the Inducement Warrants concurrently with or within 30 days following the consummation of a fundamental transaction.

However, in the event of a fundamental transaction which is not in our control, including a fundamental transaction not approved by our board of directors, the Inducement Warrant Holders will only be entitled to receive from us or our successor entity, as of the date of consummation of such fundamental transaction, the same type or form of consideration (and in the same proportion), at the Black Scholes Value of the unexercised portion of the Inducement Warrant that is being offered and paid to the holders of our common stock in connection with the fundamental transaction, whether that consideration is in the form of cash, stock or any combination of cash and stock, or whether the holders of our common stock are given the choice to receive alternative forms of consideration in connection with the fundamental transaction.

Transferability

Subject to applicable laws, an Inducement Warrant may be transferred at the option of the holder upon surrender of the Inducement Warrant to us together with the appropriate instruments of transfer.

Fractional Shares

No fractional shares of common stock will be issued upon the exercise of the Inducement Warrants. Rather, the number of shares of common stock to be issued will, at our election, either be rounded up to the next whole share or we will pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the exercise price.

Trading Market

There is no established trading market for the Inducement Warrants, and we do not expect an active trading market to develop. We do not intend to apply to list the Inducement Warrants on any securities exchange or other trading market. Without a trading market, the liquidity of the Inducement Warrants will be extremely limited.

Except as otherwise provided in the Inducement Warrants or by virtue of the holder’s ownership of shares of our common stock, such holder of Inducement Warrants does not have the rights or privileges of a holder of our common stock, including any voting rights or dividends, until such holder exercises such holder’s Inducement Warrants.

Waivers and Amendments

The Inducement Warrant may be modified or amended or the provisions of the Inducement Warrant waived with our and the holder’s written consent. The Company agreed that for a year following the date of the Inducement Letters, that none of the terms offered to any holders of the Company’s common stock purchase warrants with respect to any other agreement related to the exercise of such warrants

(or any amendment, modification or waiver thereof), is or will be more favorable to such holder than those of the Inducement Warrant Holders.

Background and Reasons for the Inducement Offer

In approving the Inducement Offer, the Board of Directors considered the pros and cons of the Inducement Offer versus other alternatives for raising capital, and the immediate working capital needs of the Company, and determined that the Inducement Offer was in the best interests of the Company and its stockholders.

Interests of Certain Parties

No person who has been a Director or executive officer of the Company at any time since January 1, 2024, or any associate thereof, has or had a substantial interest in the Inducement Offer.

Nasdaq Marketplace Requirements and the Necessity of Stockholder Approval

Our Common Stock is currently listed on the Nasdaq Capital Market and, as such, the Company is subject to Nasdaq’s rules. Nasdaq Rule 5635(d) requires the Company to obtain stockholder approval prior to the issuance of shares of Common Stock in connection with certain non-public offerings involving the sale, issuance or potential issuance by the Company of shares of Common Stock (and/or securities convertible into or exercisable for shares of Common Stock) equal to 20% or more of the shares of Common Stock outstanding prior to such issuance where the price of the Common Stock to be issued is below the “Minimum Price.” “Minimum Price” means a price that is the lower of: (i) the Nasdaq Official Closing Price (as reflected on Nasdaq.com) immediately preceding the signing of the binding agreement; or (ii) the average Nasdaq Official Closing Price of the Common Stock (as reflected on Nasdaq.com) for the five trading days immediately preceding the signing of the binding agreement. Shares of Common Stock issuable upon the exercise or conversion of warrants, options, debt instruments, preferred stock or other equity securities issued or granted in such non-public offerings will be considered shares issued in such a transaction in determining whether the 20% limit has been reached, except in certain circumstances such as issuing warrants that are not exercisable for a minimum of six months and have an exercise price that exceeds market value. The Company believes that the issuance of all shares of Common Stock upon full exercise of the Inducement Warrants requires stockholder approval.

If our stockholders do not approve this proposal, the Inducement Warrants will not be exercisable in a manner that complies with Nasdaq Rule 5635(d). Failure to obtain such approval may discourage future investors from engaging in future financings with us. If these consequences occur, we may have difficulty finding alternative sources of capital to fund our operations in the future on terms favorable to us or at all. We can provide no assurance that we would be successful in raising funds pursuant to additional equity or debt financings or that such funds could be raised at prices that would not create substantial dilution for our existing stockholders. The Company will also be obligated to incur additional management resources and expenses to call and hold a meeting every 90 days thereafter to seek such stockholder approval until the date stockholder approval is obtained.

If the stockholders approve this proposal, the Inducement Warrants will be exercisable at any time following receipt of such approval until their expiration 5 years or 24 months, as applicable, after such approval is obtained, which could result in substantial dilution to our stockholders.

Vote Required

The affirmative vote of the holders of a majority of the voting power of the shares present by remote communication or represented by proxy at the Annual Meeting and entitled to vote is required for the approval of the Inducement Warrant Proposal. Broker non-votes, if any, will have no effect on the outcome of this proposal. Abstentions will have the same effect as a vote against the matter.

OUR BOARD UNANIMOUSLY RECOMMENDS A VOTE “FOR” PROPOSAL 3.

​

PROPOSAL 4 - APPROVAL OF A PROPOSED AMENDMENT TO OUR CERTIFICATE OF
INCORPORATION TO EFFECT A REVERSE SPLIT OF OUR OUTSTANDING COMMON STOCK TO
ENABLE THE COMPANY TO COMPLY WITH THE NASDAQ STOCK MARKET’S CONTINUED
LISTING REQUIREMENTS

General

The Board has unanimously approved an amendment to the Company’s Certificate of Incorporation to effect a reverse split of the Company’s Common Stock any time prior to the first anniversary of its approval by the stockholders at a ratio in the range of 1-for-2 to 1-for-30, to be determined at the discretion of the Board, whereby each outstanding 2 to 30 shares would be combined, converted and changed into 1 share of the Company’s Common Stock. A form of the certificate of amendment to the Certificate of Incorporation for the reverse stock split (the “Reverse Stock Split Certificate of Amendment”) is attached hereto as Appendix A. The following discussion is qualified in its entirety by the full text of the Reverse Stock Split Certificate of Amendment, which is incorporated herein by reference.

The Board has recommended the proposed Reverse Stock Split Certificate of Amendment to effect the reverse stock split be presented to the Company’s stockholders for approval. If the Reverse Stock Split Certificate of Amendment is approved by a majority of the Company’s stockholders, the Board will have discretion to determine, as it deems to be in the best interest of the Company’s stockholders, the specific ratio to be used within the range described above and the timing of the reverse stock split, which must occur any time prior to the first anniversary of its approval by the stockholders. The Board believes that stockholder approval of the range of reverse stock split ratios (as opposed to approval of a single reverse stock split ratio) provides the Board with maximum flexibility to achieve the purpose of a reverse stock split, as discussed below, and therefore is in the best interests of the Company and its stockholders.

The Board may, in its discretion, determine not to effect the reverse stock split if it determines, subsequent to obtaining stockholder approval, that such action is not in the best interests of the Company. By voting in favor of the reverse stock split, you are expressly authorizing the Board to determine not to proceed with, and abandon, the reverse stock split if it should so decide. The Board may, in its discretion, determine not to effect the reverse stock split if it determines, subsequent to obtaining the stockholder approval anticipated by the approval of Proposal 3, that such action is not in the best interests of the Company.

Reasons for the Reverse Stock Split

The Company’s Common Stock is quoted on the Nasdaq Capital Market under the symbol “HSDT.”

For the Common Stock to continue trading on the Nasdaq Capital Market, the Company must comply with various listing standards, including that our Common Stock maintain a minimum bid price of $1.00 per share, as set forth in Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Requirement”). The closing price of the Company’s Common Stock on the Nasdaq Capital Market on March 19, 2025 was $0.40 per share and, over the prior 52 weeks, the closing price of the Company’s Common Stock has ranged from $0.374 to $6.48 per share.

As previously disclosed, on August 9, 2024, we received written notice (the “Notification Letter”) from The Nasdaq Stock Market LLC (“Nasdaq”) notifying us that the Company was not in compliance with the minimum bid price requirements set forth in Nasdaq Listing Rule 5550(a)(2) for continued listing on the Nasdaq Capital Market. Nasdaq Listing Rule 5550(a)(2) requires listed securities maintain a minimum closing bid price of $1.00 per share, and Nasdaq Listing Rule 5810(c)(3)(A) provides that a failure to meet the minimum closing bid price requirement exists if the deficiency continues for a period of 30 consecutive business days preceding the Notification Letter. Based on the closing bid price of the Company’s Common Stock for the 30 consecutive business days prior to the date of the Notification Letter, the Company did not meet the minimum closing bid price requirement. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company was provided a period of 180 calendar days in which to regain compliance, which expired on February 5, 2025. The Company had a hearing with the Nasdaq Hearing Panel on March 18, 2025. At the hearing, we presented our plan for regaining compliance with the Minimum Bid Price Requirement and requested a further extension so that we may complete the execution of our plan. Although we believe our plan will be sufficient to enable us to regain compliance, no assurance can be provided that Nasdaq will ultimately accept our plan or that we will ultimately regain compliance with the Minimum Bid Price Requirement. As of the date hereof, we have not received a determination from the hearings panel. Our common stock will remain listed and eligible for trading on Nasdaq pending the ultimate conclusion of the hearing process.

The Board is asking the stockholders to grant it the authority, at its discretion, to effect a reverse stock split, which the Board believes is an effective way to increase the minimum bid price of our Common Stock proportionately by reducing the number of outstanding

shares of Common Stock and put us in a position to regain compliance with the Minimum Bid Price Requirement. The Board further believes that the increased market price of our Common Stock expected as a result of implementing the reverse stock split may improve marketability and liquidity of our Common Stock and may encourage trading.

In evaluating whether or not to recommend that stockholders authorize the reverse stock split, in addition to the considerations described above, the Board took into account various negative factors associated with a reverse stock split. These factors include: the negative perception of reverse stock splits held by some investors, analysts, and other stock market participants; the fact that the stock price of some companies that have effected reverse stock splits has subsequently declined, with a corresponding decline in market capitalization; the adverse effect on liquidity that might be caused by a reduced number of shares outstanding; and the costs associated with implementing a reverse stock split. Conversely, we believe the current low market price of our Common Stock impairs its acceptability to important segments of the institutional investor community and the investing public. Many investors look upon low-priced stock as unduly speculative in nature and, as a matter of policy, avoid investment in such stocks. We believe that the low market price of our Common Stock has reduced the effective marketability of our shares because of the reluctance of many brokerage firms to recommend low-priced stock to their clients. Further, a variety of brokerage house policies and practices tend to discourage individual brokers within those firms from dealing in low-priced stocks. Some of those policies and practices pertain to the payment of brokers’ commissions and to time-consuming procedures that function to make the handling of low-priced stocks unattractive to brokers from an economic standpoint. In addition, the structure of trading commissions also tends to have an adverse impact upon holders of low-priced stock because the brokerage commission on a sale of low-priced stock generally represents a higher percentage of the sales price than the commission on a relatively higher-priced issue.

The Board believes that maintaining the listing of the Company’s Common Stock on Nasdaq is in the best interests of the Company and its stockholders. The Board believes that the delisting of the Company’s Common Stock from Nasdaq would impair our ability to raise additional funds and result in lower prices and larger spreads in the bid and ask prices for the Company’s Common Stock, among other things. See “Certain Risk Factors Associated with the Reverse Stock Split or Nasdaq Delisting” below for more information.

Determination of the Reverse Stock Split Ratio

Our Board only intends to implement the reverse stock split to the extent it believes necessary to maintain the Company’s listing on Nasdaq. In determining the ratio to be used, the Board will consider various factors, including but not limited to:

Impact of the Reverse Stock Split, if Implemented

The Company’s Certificate of Incorporation, as previously corrected (the “Certificate of Incorporation”), currently authorizes the issuance of 160,000,000 shares of capital stock, consisting of 150,000,000 shares of Class A Common Stock, par value $0.001 per share, and 10,000,000 shares of Preferred Stock. On March 12, 2025, the Company had: 6,126,778 shares of Common Stock issued and outstanding, 2,678,000 unissued shares of Common Stock held in abeyance from warrant exercise, 2,729,689 shares of Common Stock issuable upon the exercise of outstanding options, 7,703,490 shares of Common Stock issuable upon the exercise of outstanding warrants and 123,989 shares of Common Stock reserved for future issuance under the Company’s 2022 Equity Incentive Plan and 2021 Inducement Plan.

As a matter of Delaware law, the implementation of a reverse stock split does not require a reduction in the total number of authorized shares. If the Company’s stockholders adopt and approve the Reverse Stock Split Certificate of Amendment and the reverse stock split

is implemented by the Company, the authorized number of shares of the Company’s Common Stock would not be reduced by the reverse stock split ratio determined by the Board.

If approved and effected, the reverse stock split will automatically apply to all shares of the Company’s Common Stock, and each stockholder will own a reduced number of shares of the Company’s Common Stock. However, except for adjustments that may result from the treatment of fractional shares, as described below, or as a result of adjustments to the conversion prices of certain convertible securities, as described below, the reverse stock split will not affect any stockholder’s percentage ownership or proportionate voting power.

On January 21, 2025, the Company entered into Inducement Letters with certain Inducement Warrant Holders, as more fully described herein in Proposal 3. If proposal 3 is approved by our stockholders and all of the Inducement Warrants are exercised, we expect to have an additional 6,213,888 shares of common stock outstanding.  Based on the Company’s capitalization as of March 12, 2025, the principal effect of the reverse stock split (at a ratio between 1-for-2 and 1-for-30), not taking into account the treatment of fractional shares described under “—Procedure for Effecting the Reverse Stock Split—Treatment of Fractional Shares” below, would be that:

The following table contains approximate information relating to our Common Stock immediately following the reverse stock split under certain possible exchange ratios, based on share information as of March 12, 2025. All share numbers are rounded down to the

nearest whole share but otherwise do not reflect the potential effect of rounding down for fractional shares that may result from the reverse stock split.

​

See also “Certain Risk Factors Associated with the Reverse Stock Split or Nasdaq Delisting” and “—Procedure for Effecting the Reverse Stock Split—Treatment of Fractional Shares” below for additional information regarding the potential impact of the reverse stock split.

Anti-Takeover and Dilutive Effects

The number of authorized shares of our Common Stock and preferred stock will not be reduced as a result of the reverse stock split. The Common Stock and preferred stock that is authorized but unissued provide the Board with flexibility to effect, among other transactions, public or private financings, acquisitions, stock dividends, stock splits and the granting of equity incentive awards. However, these authorized but unissued shares may also be used by the Board, consistent with and subject to its fiduciary duties, to deter future attempts to gain control of us or make such actions more expensive and less desirable. Following the reverse stock split, our Board would continue to have the authority to issue additional shares from time to time without further action by the stockholders except as may be required by applicable law or regulations. The Reverse Stock Split Certificate of Amendment is not being recommended in response to any specific effort of which we are aware to obtain control of us, nor does our Board have any present intent to use the authorized but unissued Common Stock or preferred stock to impede a takeover attempt.

The Company expects to require additional financing to fund its ongoing activities. Other than the foregoing, and except for the Company’s obligation to issue Common Stock upon the exercise of outstanding options and warrants, we have no specific plan, commitment, arrangement, understanding or agreement, either oral or written, regarding the issuance of Common Stock subsequent to the reverse stock split at this time.

Certain Risk Factors Associated with the Reverse Stock Split or Nasdaq Delisting

A reverse stock split may negatively impact the market for our Common Stock.

Factors such as our financial results, market conditions and the market perception of our business may adversely affect the market price of our Common Stock. As a result, there can be no assurance that the total market capitalization of our Common Stock after the proposed reverse stock split will be equal to or greater than the total market capitalization before the proposed reverse stock split or that the per share market price of our Common Stock following the reverse stock split will increase in proportion to the reduction in the number of shares of Common Stock outstanding before the reverse stock split. A decline in the market price of our Common Stock after the reverse stock split may result in a greater percentage decline than would occur in the absence of a reverse stock split, and the liquidity of our Common Stock could be adversely affected following such a reverse stock split.

In addition, the reverse stock split may increase the number of stockholders who own odd lots (less than 100 shares). Any stockholder who owns fewer than 2 to 30 shares of Common Stock, depending on the final ratio, prior to the reverse stock split will own fewer than 100 shares of Common Stock following the reverse stock split. Stockholders who hold odd lots typically experience an increase in the cost of selling their shares and may have greater difficulty in effecting sales. Furthermore, some stockholders may cease being stockholders of the Company following the reverse stock split. Any stockholder who owns fewer than 2 to 30 shares of Common Stock, depending on the final ratio, prior to the reverse stock split will own less than one share of Common Stock following the reverse stock split and therefore such stockholder will receive cash equal to the market value of such fractional share and cease being a stockholder of the Company, as further described below under “—Procedure for Effecting the Reverse Stock Split—Treatment of Fractional Shares”.

The market price of our Common Stock will also be based on our performance and other factors, including those factors listed under the heading “Risk Factors” and elsewhere in our Annual Report on Form 10-K for the year ended December 31, 2024, and other reports that we file with the SEC. There can also be no assurance that the minimum bid price per share of our Common Stock will remain in excess of $1.00 following the reverse stock split for a sustained period of time, if at all.

Nasdaq may delist the Company’s Common Stock, which could seriously harm the liquidity of the Common Stock and the Company’s ability to raise capital.

On August 9, 2024, we received the Notification Letter from Nasdaq notifying us that the Company was not in compliance with the minimum bid price requirements set forth in Nasdaq Listing Rule 5550(a)(2) for continued listing on the Nasdaq Capital Market. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company was provided a period of 180 calendar days in which to regain compliance, which expired on February 5, 2025. The Company had a hearing with the Nasdaq Hearing Panel on March 18, 2025. At the hearing, we presented our plan for regaining compliance with the Minimum Bid Price Requirement and requested a further extension so that we may complete the execution of our plan. Although we believe our plan will be sufficient to enable us to regain compliance, no assurance can be provided that Nasdaq will ultimately accept our plan or that we will ultimately regain compliance with the Minimum Bid Price Requirement. As of the date of this report, we have not received a determination from the hearings panel. If the Company is unable to regain compliance with the Minimum Bid Price Requirement or other listing requirements, the Company could lose eligibility for continued listing on the Nasdaq Capital Market or any comparable trading market.

If we cease to be eligible to trade on Nasdaq:

A reverse stock split would increase the Company’s authorized but unissued shares of Common Stock, which could negatively impact a potential investor if they purchased shares of Common Stock.

Because the number of authorized shares of the Company’s Common Stock will not be reduced proportionately, the reverse stock split will increase the Board’s ability to issue authorized and unissued shares without further stockholder action. The issuance of additional shares of Common Stock or securities convertible into Common Stock may have a dilutive effect on earnings per share and relative voting power and may cause a decline in the trading price of the Common Stock. The Company could use the shares that are available for future issuance in dilutive equity financing transactions, or to oppose a hostile takeover attempt or delay or prevent changes in control or changes in or removal of management, including transactions that are favored by a majority of the stockholders or in which the stockholders might otherwise receive a premium for their shares over then-current market prices or benefit in some other manner.

The Company expects to require additional financing to fund its ongoing activities. Other than the foregoing, and except for the Company’s obligation to issue Common Stock upon the exercise of outstanding options and warrants, the Company has no specific plan, commitment, arrangement, understanding or agreement, either oral or written, regarding the issuance of Common Stock subsequent to the reverse stock split at this time.

Procedure for Effecting the Reverse Stock Split

When and if the Board decides to implement the reverse stock split at any time before the first anniversary of its approval by the stockholders, the Company will promptly file the Reverse Stock Split Certificate of Amendment with the Secretary of State of the State of Delaware to amend its existing Certificate of Incorporation. The reverse stock split will become effective upon filing the Reverse Stock Split Certificate of Amendment with the Secretary of State of the State of Delaware or at a later date and time set forth therein, if any, which effective date and time is referred to as the “reverse stock split effective date”. Beginning on the reverse stock split effective date, each certificate representing pre-reverse stock split shares will be deemed for all corporate purposes to evidence ownership of post-reverse stock split shares. The text of the Reverse Stock Split Certificate of Amendment is set forth in Appendix A to this proxy statement. The text of the Reverse Stock Split Certificate of Amendment is subject to modification to include such changes as may be required by the office of the Secretary of State of the State of Delaware and as the Board deems necessary and advisable to effect the reverse stock split, including the applicable ratio for the reverse stock split.

After the reverse stock split effective date, our Common Stock will have a new CUSIP number, which is a number used to identify securities, and stock certificates with the old CUSIP number will need to be exchanged for stock certificates with the new CUSIP number using the procedures described below.

Exchange of Stock Certificates

Each stock certificate that, immediately prior to the reverse stock split effective date, represented shares of Common Stock that were issued and outstanding immediately prior to the reverse stock split effective date shall, from and after the reverse stock split effective date, automatically and without the necessity of presenting the same for exchange, represent that number of whole shares of Common Stock after the reverse stock split effective date into which the shares of Common Stock formerly represented by such certificate shall have been combined (as well as the right to receive cash in lieu of fractional shares of Common Stock after the reverse stock split effective date), provided however, that each person of record holding a certificate that represented shares of Common Stock that were issued and outstanding immediately prior to the reverse stock split effective date shall receive, upon surrender of such certificate, a new certificate evidencing and representing the number of whole shares of Common Stock after the reverse stock split effective date into which the shares of Common Stock formerly represented by such certificate shall have been combined.

Treatment of Fractional Shares

To avoid the existence of fractional shares of Common Stock after the reverse stock split, fractional shares that would be created as a result of the reverse stock split will be rounded down to the next whole share and the stockholder will receive cash equal to the market value of the fractional share, determined by multiplying such fraction by the closing sales price of the Company’s Common Stock as reported on Nasdaq on the last trading day before the reverse stock split effective date (as adjusted to give effect to the reverse stock split). The ownership of a fractional share will not give the holder any voting, dividend or other right except to receive the cash payment therefor. If a stockholder is entitled to a cash payment in lieu of any fractional share, a check will be mailed to the stockholder’s registered address as soon as practicable after the reverse stock split effective date. By signing and cashing the check, stockholders will warrant that they owned the shares of Common Stock for which they received such cash payment.

No Appraisal Rights

Under the Delaware General Corporation Law, our stockholders do not have a right to dissent and are not entitled to appraisal rights with respect to the proposed Reverse Stock Split Certificate of Amendment to effect the reverse stock split, and we will not independently provide our stockholders with any such rights.

Material Federal Income Tax Consequences

The following discussion of certain U.S. federal income tax consequences to the Company’s stockholders of the reverse stock split, if effected, does not purport to be a complete discussion of all of the possible U.S. federal income tax consequences and is included for general information only. It not intended as tax advice to any person and is not a comprehensive description of the tax consequences that may be relevant to each stockholder’s own particular circumstances. The discussion is based on the Internal Revenue Code of 1986, as amended (the “Code”), applicable Treasury Regulations promulgated thereunder, judicial authority and current administrative rulings and practices as in effect on the date of this proxy statement. Changes to the laws could alter the tax consequences described below,
