2025 SPECIAL MEETING OF STOCKHOLDERS
October 30, 2025

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING

Who is soliciting my vote?

The Board of Directors (the “Board”) of Solana Company (f/k/a 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 special meeting of stockholders to be held on October 30, 2025, at 10:00 a.m. Eastern Time, virtually at www.virtualshareholdermeeting.com/HSDT2025SM2 and any adjournment or postponement of such meeting (the “Special Meeting”).

The Notice of Special Meeting of Stockholders (the “Notice”), proxy statement and form of proxy card are expected to be first mailed to stockholders of record on or about October 14, 2025.

What is the purpose of the Special Meeting?

At the Special Meeting, you will be voting on:

•

Proposal 1: To elect one new director to our Board of Directors;

•

Proposal 4: To approve an amendment to our 2022 Equity Incentive Plan to increase the number of shares of common stock available for issuance thereunder by 4,000,000 shares; and

•

Proposal 5: To authorize one or more adjournments of the Special Meeting to solicit additional proxies in the event there are insufficient votes to approve Proposals 1, 2, 3 or 4.

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

Who is entitled to vote?

You may vote if you owned shares of our Common Stock at the close of business on September 26, 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. Each share of Common Stock is entitled to vote on each matter properly brought before the meeting. As of September 26, 2025, we had 40,299,220 shares of Common Stock outstanding and entitled to vote.

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

TABLE OF CONTENTS

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 Special Meeting.

Can I vote my shares without attending the Special 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 Special Meeting and vote my shares virtually?

The Special meeting will be held entirely online. To participate in the Special 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 Special 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 Special 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 Special Meeting; by submitting a later-dated proxy via internet or phone; or by voting in person at the Special 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 October 29, 2025. Your virtual attendance at the Special Meeting will not cause your previously granted proxy to be revoked unless you electronically vote at the Special 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 person 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 Special Meeting.

TABLE OF CONTENTS

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.

How many shares must be present to hold the meeting?

In order for us to conduct the Special Meeting, holders of one-third of the voting power of our outstanding shares of stock entitled to vote as of the Record Date, September 26, 2025, must be present by remote communication or by proxy at the Special 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 Special 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 Special Meeting and entitled to vote generally on the election of directors. Since we only have one director nominee nominated for election to the Board at the Special Meeting, the nominee will be elected as long as he receives at least one vote. 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 — Strategic Advisor 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 Special Meeting and entitled to vote is required to approve this 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 3 — Cryptocurrency 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 Special Meeting and entitled to vote is required to approve this 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 — Amendment to the 2022 Equity Incentive Plan 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 Special Meeting and entitled to vote is required to approve the proposed amendment of the 2022 Equity Incentive Plan. 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 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 Special Meeting and entitled to vote is required for any adjournment of the Special Meeting to solicit additional proxies in the event there are insufficient votes to approve Proposals 1, 2, 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 Special Meeting, nor is it aware of any other matter to be presented for action at the Special 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 Special 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 Special Meeting.

TABLE OF CONTENTS

PROPOSAL 1

ELECTION OF DIRECTORS

General

Upon shareholder approval of the director nominee to the Board, Jeff Mathiesen will resign from 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. It is the Company’s policy to invite its nominees for directors to attend the Special Meeting. 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 Special Meeting and entitled to vote generally on the election of directors. Accordingly, the sole nominee receiving a plurality of the 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” THE DIRECTOR NOMINEE.

TABLE OF CONTENTS

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 determined that Mr. Jiang is not independent. In making this determination, 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.

Board Leadership Structure

The Board is currently chaired by Joseph Chee. Mr. Chee does not satisfy the independence criteria set forth in the Nasdaq rules and is not “independent” for purposes of serving on 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.

TABLE OF CONTENTS

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:

Name	Audit Committee	Compensation Committee	Nominating and Corporate Governance Committee
Paul Buckman	X*	X	X
Edward M. Straw	X	X*	X
Blane Walter	X
Sherrie Perkins		X	X*

Committee Chairperson

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:

•

evaluating the performance of and assessing the qualifications of the independent auditors;

•

determining and approving the engagement of the independent auditors;

•

determining whether to retain or terminate the existing independent auditors or to appoint and engage new independent auditors;

•

reviewing and approving the retention of the independent auditors to perform any proposed permissible non-audit services;

•

monitoring the rotation of partners of the independent auditors on the Company’s audit engagement team as required by law;

•

reviewing and approving or rejecting transactions between the Company and any related persons;

•

conferring with management and the independent auditors regarding the scope, adequacy and effectiveness of internal control over financial reporting;

•

establishing procedures, as required under applicable law, for the receipt, retention and treatment of complaints received by the Company regarding accounting, internal controls or auditing matters and the confidential and anonymous submission by employees of concerns regarding questionable accounting or auditing matters; and

•

meeting to review the Company’s annual audited financial statements and quarterly financial statements with management and the independent auditor.

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.solanacompany.co.

TABLE OF CONTENTS

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.

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.solanacompany.co.

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

•

reviewing, approving for adoption or recommending for adoption and overseeing the Company’s compensation strategy, policies, plans and programs, including establishing corporate and individual performance objectives relevant to the compensation of the Company’s executive officers and other senior management and evaluation of performance in light of these stated objectives;

•

reviewing, approving or recommending to the Board for approval the compensation and other terms of employment or service, including severance and change-in-control arrangements, of the Company’s Chief Executive Officer, the other executive officers and the directors;

•

reviewing the Company’s compensation practices and policies as related to risk management to determine whether such practices and policies are reasonably likely to have a material adverse effect on the Company;

•

administering and enforcing the Company’s Policy for the Recovery of Erroneously Awarded Compensation; and

•

administering the Company’s equity compensation plans, pension and profit-sharing plans, deferred compensation plans and other similar plans and programs.

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.

TABLE OF CONTENTS

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.solanacompany.co.

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

•

identifying, reviewing and evaluating candidates to serve as directors of the Company (consistent with criteria approved by the Board);

•

reviewing and evaluating incumbent directors;

•

selecting or recommending to the Board for selection candidates for election to the Board of Directors;

•

making recommendations to the Board regarding the membership of the committees of the Board;

•

assessing the performance of management and the Board; and

•

developing a set of corporate governance principles for the Company.

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”.

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.solanacompany.co. 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.

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

TABLE OF CONTENTS

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

Our equity-based incentive awards which are mainly comprised of stock options are designed to align our interests with those of our employees and consultants, including our named executive officers. Our Compensation Committee has responsibility for granting equity-based incentive awards to our named executive officers. Our Compensation Committee has not established policies and practices regarding timing of equity awards in relation to the release of material nonpublic information and does not time the public release of such information based on equity award grant dates nor for the purpose of affecting the value of executive compensation. Our compensation committee does not consider material nonpublic information in setting terms of equity awards, such as grant size or vesting conditions. Vesting of equity awards is generally tied to continuous service with us and serves as an additional retention measure. Our executives generally are awarded an initial new hire grant upon commencement of employment. Additional grants may occur periodically in order to specifically incentivize executives with respect to achieving certain corporate goals or to reward executives for exceptional performance.

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

TABLE OF CONTENTS

404,000 shares of Common Stock to Mr. Mathiesen, and an option to purchase 277,000 shares of common stock to Dr. Favit-Van Pelt pursuant to the 2022 Equity Incentive 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 Equity Incentive Plan. Each of stock options granted to Messrs. Andreeff and Mathiesen and Dr. 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.

In addition, directors receive an additional cash retainer for serving as a committee chair or member as follows:

	Audit Committee			Compensation Committee			Nominating and Corporate Governance Committee
Committee Chair		$	16,000		$	10,000		$	7,500
Committee Member (other than the Chair)		$	8,000		$	5,000		$	5,000

The equity retainer is paid 70% in options to purchase shares of our Common Stock, which vest in increments of 1/12 per month and 30% in restricted stock units (“RSUs”), which vest in increments of 1/12 per month. We also reimburse non-employee directors for reasonable expenses incurred in connection with attending Board and committee meetings. In 2024, in lieu of RSUs, our Board was granted an equivalent amount of stock options in addition to a cash payment equal to $50,000 minus the Black Scholes calculation of the value of the stock options on the grant date.

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.

On September 15, 2025, the Company entered into a Strategic Advisor Agreement with Pantera Capital Management LP (“Pantera”) and Summer Wisdom Holdings Limited (“Summer” and with Pantera, the “Advisors”), pursuant to which the Company engaged each Advisor to provide strategic advice regarding the Company’s business, operations, growth initiatives and industry trends in the crypto technology sector. The initial term is two years and automatically renews for successive one-year periods. Either party may terminate for uncured material breach after 30 days’ written notice. In connection with the agreement, the Company issued to Summer warrants to purchase shares of Common Stock equal to 3% of the aggregate number of Cash Shares and Pre-Funded Warrant Shares (“Strategic Advisor Base Warrant Shares”). In addition, upon the exercise of each Stapled Warrant, Summer will receive additional warrants to purchase its allocable portion of 5% of the Stapled Warrant Shares underlying such exercised Stapled Warrant (“Strategic Advisor Performance Shares”). The Performance Warrants have an exercise price of $0.001 per share, a five-year term from issuance, permit cashless exercise, are settled solely in shares, and terminate automatically, without consideration, to the extent unvested upon expiration. Summer is controlled by Mr. Chee, who was named Executive Chairman of the Board following the closing of the offerings.

In addition, upon the Closing, Mr. Chee and the Company entered into an executive chairman agreement (the “Executive Chairman Agreement”) dated September 18, 2025. Pursuant to the terms of the Executive Chairman Agreement, Mr. Chee received an equity award of restricted stock units (“RSUs”) equal to (i) 1% of the aggregate number of Common Stock and pre-funded warrants issued in the Offerings, plus (ii) 0.5% of the aggregate number of Common Stock underlying the stapled warrants issued in connection with the offerings for his services related to the implementation of the digital asset treasury for the Company. This amount was determined to be 1,109,118 RSUs. Further, following the closing of the Offerings and within 10 business days of the exercise of a Cash Stapled Warrant issued to investors in the Offerings, the Company shall issue to Mr. Chee an additional RSU award equal to 0.5% of the number of shares of the Company’s Common Stock issuable upon the exercise of the Cash Stapled Warrants. The vesting of each such RSU grants shall be subject to stockholder approval of the increase in the shares available under the Company’s 2022 Equity Incentive Plan, as described in Proposal 4.

PROPOSAL 4

APPROVAL OF AN AMENDMENT TO THE HELIUS MEDICAL
TECHNOLOGIES, INC. 2022 EQUITY INCENTIVE PLAN

We are asking stockholders to approve an amendment to our Helius Medical Technologies, Inc. 2022 Equity Incentive Plan (the “2022 Equity Incentive Plan”) to increase the number of shares available for issuance by 4,000,000 shares.

Overview

Our stockholders are being asked to approve Amendment 3 to the Helius Medical Technologies, Inc. 2022 Equity Incentive Plan (the “Third Amendment”). On September 25, 2025, our Board, upon the recommendation of our Compensation Committee, approved the Amendment, subject to stockholder approval at the Special Meeting. The 2022 Equity Incentive Plan was initially adopted by our Board on February 16, 2022 and by our stockholders on May 23, 2022 and was amended by Amendment 1, approved by our Board on May 30, 2024 and by our stockholders on June 27, 2024 and by the Amendment 2, approved by our Board on April 22, 2025 and on May 23, 2025 by our stockholders.

Pursuant to this proposal, stockholder approval of the Third Amendment would make available for awards under the 2022 Equity Incentive Plan an additional 4,000,000 shares of Common Stock of the Company, as described below, with such amount subject to adjustment, including under the share counting rules. Stockholder approval of the Amendment also would have an impact on certain prior grants of restricted stock units. In particular, certain restricted stock units issued pursuant to the Executive Chairman Agreement with Mr. Chee require stockholder approval of this Third Amendment in order for sufficient shares to be available under the 2022 Equity Incentive Plan. These awards shall not become payable with respect to any shares of common stock unless and until stockholders approve the Third Amendment at the Special Meeting.

The actual text of the Third Amendment is attached to this proxy statement as Appendix A.

Our officers and directors may have an interest in this Proposal 4 due to their participation in the 2022 Equity Incentive Plan.

As of the Record Date, prior to stockholder approval of the Amendment, we had 14,485 shares of our Common Stock remaining available for issuance for awards under the 2022 Equity Incentive Plan.

Why We Believe You Should Vote for this Proposal

The Third Amendment continues to authorize the Compensation Committee to grant stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance awards, and other forms of stock awards to employees, directors and consultants, including employees and consultants of the affiliates of the Company.

We use awards under the 2022 Equity Incentive Plan to attract and retain employees, ensure that our compensation program provides appropriate incentives to motivate our key employees, consultants, officers and non-employee directors to contribute to our long-term performance and growth, develop a culture of ownership and further align the interests of the participants and our stockholders. In September 2025, the Company adopted and implemented a Solana treasury strategy. The digital asset treasury and the life sciences markets are highly competitive, and our results are largely attributable to the talents, expertise, efforts and dedication of our employees, consultants, officers and non-employee directors. Our compensation program, including the granting of equity compensation, is a crucial way to attract and recruit new employees and consultants and retain existing employees and consultants, with equity compensation serving as our primary recruitment, retention and motivational tool as opposed to cash compensation. Stockholder approval of the Third Amendment will permit us to continue to grant equity compensation awards to our key employees, consultants, officers and non-employee directors in furtherance of this philosophy.

If the Third Amendment is not approved, we may be compelled to significantly increase the cash component of our employee and director compensation, which approach may not necessarily align

TABLE OF CONTENTS

employee and director compensation interests with the investment interests of our stockholders. Replacing equity awards with cash also would increase cash compensation expense and use cash that could be better utilized.

Material Changes from the 2022 Equity Incentive Plan

The Third Amendment increases the number of shares of Common Stock available for awards under the 2022 Equity Incentive Plan by 4,000,000 shares of Common Stock.

We are not seeking to make any other material changes to the terms of the 2022 Equity Incentive Plan.

Summary of the 2022 Equity Incentive Plan, as proposed to be amended

The material features of the 2022 Equity Incentive Plan are described below. The following description of the 2022 Equity Incentive Plan is a summary only and is qualified in its entirety by reference to the complete text of the 2022 Equity Incentive Plan, as amended by Amendment 1 and Amendment 2 thereto. Stockholders are urged to read the proposed Third Amendment, attached to this proxy statement as Appendix A. If our stockholders approve the Third Amendment, a registration statement on Form S-8 covering the shares added to the share reserve will be filed with the SEC.

General

The 2022 Equity Incentive Plan provides that all current and prospective employees, consultants and non-employee directors of the Company or its affiliates may be granted the following types of awards: options to acquire shares of the Company’s Common Stock; shares of restricted stock; or other stock-based awards including shares of Common Stock not subject to any restrictions or conditions, shares of Common Stock in payment of the amounts due under an incentive or performance plan sponsored or maintained by the Company or an Affiliate, stock appreciation rights, stock equivalent units, restricted stock units, performance shares, performance units and awards valued by reference to book value of shares of Common Stock. Eligibility for awards under the 2022 Equity Incentive Plan is determined by the Plan Administrator (as defined below), in its sole discretion.

Awards

The 2022 Equity Incentive Plan provides for the grant of incentive stock options (“ISOs”), nonstatutory stock options (“NSOs”), stock appreciation rights, restricted stock awards, restricted stock unit awards, performance awards and other forms of awards to employees, directors and consultants, including employees and consultants of the Company’s affiliates.

Authorized Shares

If this Proposal is approved by stockholders, the aggregate number of shares of our Common Stock that may be issued under the 2022 Equity Incentive Plan will not exceed the sum of (1) 4,000,000 and (2) any 2018 Omnibus Incentive Plan’s Returning Shares following the effective date of Amendment. In addition, the number of shares of Common Stock reserved for issuance under the 2022 Equity Incentive Plan will automatically increase on January 1st of each calendar year for a period of five years commencing on January 1, 2025 and ending on (and including) 1, 2029, by an amount equal to 5% of the Fully Diluted Shares (as defined in the 2022 Equity Incentive Plan) as of the last day of the preceding calendar year, provided, however that the Board may act prior to the effective date of any such annual increase to provide that the increase for such year will be a lesser number of shares of Common Stock. The maximum number of shares of Common Stock that may be issued pursuant to the exercise of ISOs is 11,212,720 shares. In addition, pursuant to Amendment 2, on May 23, 2025, there was an automatic increase in the aggregate number of shares of Common Stock that may be issued pursuant to Awards (as defined in the 2022 Equity Incentive Plan) to an amount equal to 20% of the Fully Diluted Shares (as defined in the 2022 Equity Incentive Plan) as of the date thereof, provided, however that the Board may act prior to the effective date of any such increase to provide that the increase will be a lesser number of shares of Common Stock.

For the purpose of the 2022 Equity Incentive Plan, “Fully Diluted Shares” shall mean an amount equal to the number of shares of Common Stock (i) outstanding and (ii) issuable upon exercise, conversion or

TABLE OF CONTENTS

settlement of outstanding Awards under the Plan and any other outstanding options, warrants or other securities of the Company that are (directly or indirectly) convertible or exchangeable into or exercisable for shares of Common Stock, and in the case of warrants, assuming the exercise of any zero cash exercise provision, in each case as of the close of business of the Company on such date and without regard to any vesting conditions or other limitations on the immediate ability to convert, exchange or exercise such rights. For purposes of calculating the number of Fully Diluted Shares, if the number of shares subject to an outstanding right to acquire shares is variable, then the number of shares of Common Stock.

Shares subject to stock awards granted under the 2022 Equity Incentive Plan that expire or terminate without being exercised in full or that are paid out in cash rather than in shares do not reduce the number of shares available for issuance under the 2022 Equity Incentive Plan. If any shares of Common Stock issued pursuant to a stock award are forfeited back to or repurchased or reacquired by the Company (1) because of a failure to meet a contingency or condition required for the vesting of such shares; (2) to satisfy the exercise, strike or purchase price of an award; or (3) to satisfy a tax withholding obligation in connection with an award, the shares that are forfeited or repurchased or reacquired will revert to and again become available for issuance under the 2022 Equity Incentive Plan.

Plan Administration

The Board, or a duly authorized committee of the Board, may administer the 2022 Equity Incentive Plan (the “Plan Administrator”). The Plan Administrator may also delegate to one or more of the Company’s officers the authority to: (1) designate employees (other than officers) to receive specified stock awards; and (2) determine the number of shares subject to such stock awards. Under the 2022 Equity Incentive Plan, the Plan Administrator has the authority to determine award recipients, grant dates, the numbers and types of stock awards to be granted, the applicable fair market value, and the provisions of each stock award, including the period of exercisability and the vesting schedule applicable to a stock award.

Under the 2022 Equity Incentive Plan, the Plan Administrator also generally has the authority to effect, with the consent of any materially adversely affected participant, (A) the reduction of the exercise, purchase, or strike price of any outstanding option or stock appreciation right; (B) the cancellation of any outstanding option or stock appreciation right and the grant in substitution therefore of other awards, cash, or other consideration; or (C) any other action that is treated as a repricing under U.S. GAAP.

Eligibility and Participation

All current and prospective eligible employees and consultants and all current non-employee directors are eligible to be granted non-qualified stock options, restricted stock awards and other stock-based awards under the 2022 Equity Incentive Plan. As of September 26, 2025, we have four non-employee directors, four executive officers and approximately 17 other employees and 5 consultants eligible to receive awards under the 2022 Equity Incentive Plan. Only employees of ours and our subsidiaries are eligible to be granted ISOs, under the 2022 Equity Incentive Plan. Eligibility for awards under the 2022 Equity Incentive Plan is determined by the Plan Administrator in its sole discretion.

Types of Awards

Stock Options. ISOs and NSOs are granted under stock option agreements adopted by the Plan Administrator. The Plan Administrator determines the exercise price for stock options, within the terms and conditions of the 2022 Equity Incentive Plan; provided that the exercise price of a stock option generally cannot be less than 100% of the fair market value of Common Stock on the date of grant. Options granted under the 2022 Equity Incentive Plan vest at the rate specified in the stock option agreement as determined by the Plan Administrator.

The Plan Administrator determines the term of stock options granted under the 2022 Equity Incentive Plan, up to a maximum of 10 years. Unless the terms of an optionholder’s stock option agreement provide otherwise, if an optionholder’s service relationship with the Company or any of its affiliates ceases for any reason other than disability, death, or cause, the optionholder may generally exercise any vested options for a period of three months following the cessation of service. This period may be extended in the event that exercise of the option is prohibited by applicable securities laws. If an optionholder’s service relationship

TABLE OF CONTENTS

with the Company or any of its affiliates ceases due to death, or an optionholder dies within a certain period following cessation of service, the optionholder or a beneficiary may generally exercise any vested options for a period of 18 months following the date of death. If an optionholder’s service relationship with the Company or any of its affiliates ceases due to disability, the optionholder may generally exercise any vested options for a period of 12 months following the cessation of service. In the event of a termination for cause, options generally terminate upon the termination date. In no event may an option be exercised beyond the expiration of its term.

Acceptable consideration for the purchase of Common Stock issued upon the exercise of a stock option will be determined by the Plan Administrator and may include: (1) cash, check, bank draft or money order; (2) a broker-assisted cashless exercise; (3) the tender of shares of Common Stock previously owned by the optionholder; (4) a net exercise of the option if it is an NSO; or (5) other legal consideration approved by the Plan Administrator. Unless the Plan Administrator provides otherwise, options or stock appreciation rights generally are not transferable except by will or the laws of descent and distribution. Subject to approval of the Plan Administrator or a duly authorized officer, an option may be transferred pursuant to a domestic relations order, official marital settlement agreement, or other divorce or separation instrument.

Tax Limitations on ISOs. The aggregate fair market value, determined at the time of grant, of Common Stock with respect to ISOs that are exercisable for the first time by an award holder during any calendar year under all of the Company’s stock plans may not exceed $100,000. Options or portions thereof that exceed such limit will generally be treated as NSOs. No ISO may be granted to any person who, at the time of the grant, owns or is deemed to own stock possessing more than 10% of the Company total combined voting power or that of any of its parent or subsidiary corporations unless: (1) the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant; and (2) the term of the ISO does not exceed five years from the date of grant.

Restricted Stock Unit Awards. Restricted stock unit awards are granted under restricted stock unit award agreements adopted by the Plan Administrator. Restricted stock unit awards may be granted in consideration for any form of legal consideration that may be acceptable to the Plan Administrator and permissible under applicable law. A restricted stock unit award may be settled by cash, delivery of stock, a combination of cash and stock as deemed appropriate by the Plan Administrator, or in any other form of consideration set forth in the restricted stock unit award agreement.

Additionally, dividend equivalents may be credited in respect of shares covered by a restricted stock unit award. Except as otherwise provided in the applicable award agreement, restricted stock unit awards that have not vested will be forfeited once the participant’s continuous service ends for any reason.

Restricted Stock Awards. Restricted stock awards are granted under restricted stock award agreements adopted by the Plan Administrator. A restricted stock award may be awarded in consideration for cash, check, bank draft or money order, past or future services to the Company, or any other form of legal consideration that may be acceptable to the Board and permissible under applicable law. The Plan Administrator determines the terms and conditions of restricted stock awards, including vesting and forfeiture terms. If a participant’s service relationship with the Company ends for any reason, it may receive any or all of the shares of Common Stock held by the participant that have not vested as of the date the participant terminates service with the Company through a forfeiture condition or a repurchase right.

Stock Appreciation Rights. Stock appreciation rights are granted under stock appreciation right agreements adopted by the Plan Administrator. The Plan Administrator determines the purchase price or strike price for a stock appreciation right, which generally cannot be less than 100% of the fair market value of Common Stock on the date of grant. A stock appreciation right granted under the 2022 Equity Incentive Plan vests at the rate specified in the stock appreciation right agreement as determined by the Plan Administrator. Stock appreciation rights may be settled in cash or shares of Common Stock or in any other form of payment as determined by the Board and specified in the stock appreciation right agreement.

The Plan Administrator determines the term of stock appreciation rights granted under the 2022 Equity Incentive Plan, up to a maximum of 10 years. If a participant’s service relationship with the Company or any of its affiliates ceases for any reason other than cause, disability, or death, the participant may generally exercise any vested stock appreciation right for a period of three months following the cessation

TABLE OF CONTENTS

of service. This period may be further extended in the event that exercise of the stock appreciation right following such a termination of service is prohibited by applicable securities laws. If a participant’s service relationship with the Company, or any of its affiliates, ceases due to disability or death, or a participant dies within a certain period following cessation of service, the participant or a beneficiary may generally exercise any vested stock appreciation right for a period of 12 months in the event of disability and 18 months in the event of death. In the event of a termination for cause, stock appreciation rights generally terminate immediately upon the occurrence of the event giving rise to the termination of the individual for cause. In no event may a stock appreciation right be exercised beyond the expiration of its term.

Performance Awards. The 2022 Equity Incentive Plan permits the grant of performance awards that may be settled in stock, cash or other property, as determined by the Plan Administrator. Performance awards may be structured so that the stock or cash will be issued or paid only following the achievement of certain pre-established performance goals during a designated performance period. Performance awards that are settled in cash or other property are not required to be valued in whole or in part by reference to, or otherwise based on, the Common Stock.

The performance goals may be based on any measure of performance selected by the Board. The performance goals may be based on company-wide performance or performance of one or more business units, divisions, affiliates, or business segments, and may be either absolute or relative to the performance of one or more comparable companies or the performance of one or more relevant indices. Unless specified otherwise by the Board at the time the performance award is granted, the Board will appropriately make adjustments in the method of calculating the attainment of performance goals as follows: (i) to exclude restructuring charges; (ii) to exclude exchange rate effects; (iii) to exclude the effects of changes to generally accepted accounting principles; (iv) to exclude the effects of any statutory adjustments to corporate tax rates; (v) to exclude the effects of items that are “unusual” in nature or occur “infrequently” as determined under U.S. GAAP; (vi) to exclude the dilutive effects of acquisitions or joint ventures; (vii) to assume that any portion of the Company’s business which is divested achieved performance objectives at targeted levels during the balance of a performance period following such divestiture; (viii) to exclude the effect of any change in the outstanding shares of Common Stock by reason of any stock dividend or split, stock repurchase, reorganization, recapitalization, merger, consolidation, spin-off, combination or exchange of shares or other similar corporate change, or any distributions to common stockholders other than regular cash dividends; (ix) to exclude the effects of stock based compensation and the award of bonuses under the Company’s bonus plans; (x) to exclude costs incurred in connection with potential acquisitions or divestitures that are required to be expensed under U.S. GAAP; and (xi) to exclude the goodwill and intangible asset impairment charges that are required to be recorded under U.S. GAAP.

Other Stock Awards. The Plan Administrator may grant other awards based in whole or in part by reference to Common Stock. The Plan Administrator will set the number of shares under the stock award (or cash equivalent) and all other terms and conditions of such awards.

Non-Employee Director Compensation Limit

Under the 2022 Equity Incentive Plan, the aggregate value of all compensation granted or paid to any non-employee director with respect to any calendar year, including awards granted and cash fees paid by the Company to such non-employee director, will not exceed $750,000 in total value or, in the event such non-employee director is first appointed or elected to the Board during such calendar year, $1,000,000 in total value, in each case calculating the value of equity awards based on the grant date fair value of such awards for financial reporting purposes.

Changes to Capital Structure

In the event there is a specified type of change in the Company’s capital structure, such as a stock split, reverse stock split, or recapitalization, appropriate adjustments will be made to: (1) the class and maximum number of shares reserved for issuance under the 2022 Equity Incentive Plan; (2) the class and maximum number of shares by which the share reserve may increase automatically each year; (3) the class and maximum number of shares that may be issued on the exercise of ISOs; and (4) the class and number of shares and exercise price, strike price, or purchase price, if applicable, of all outstanding stock awards.

TABLE OF CONTENTS

Corporate Transactions

The following applies to stock awards under the 2022 Equity Incentive Plan in the event of a corporate transaction (as defined in the 2022 Equity Incentive Plan), unless otherwise provided in a participant’s stock award agreement or other written agreement with the Company or one of its affiliates or unless otherwise expressly provided by the Plan Administrator at the time of grant.

In the event of a corporate transaction, any stock awards outstanding under the 2022 Equity Incentive Plan may be assumed, continued or substituted for by any surviving or acquiring corporation (or its parent company), and any reacquisition or repurchase rights held by the Company with respect to the stock award may be assigned to the successor (or its parent company). If the surviving or acquiring corporation (or its parent company) does not assume, continue or substitute for such stock awards, then (i) with respect to any such stock awards that are held by participants whose continuous service has not terminated prior to the effective time of the corporate transaction, or current participants, the vesting (and exercisability, if applicable) of such stock awards will be accelerated in full to a date prior to the effective time of the corporate transaction (contingent upon the effectiveness of the corporate transaction), and such stock awards will terminate if not exercised (if applicable) at or prior to the effective time of the corporate transaction, and any reacquisition or repurchase rights held by the Company with respect to such stock awards will lapse (contingent upon the effectiveness of the corporate transaction), and (ii) any such stock awards that are held by persons other than current participants will terminate if not exercised (if applicable) prior to the effective time of the corporate transaction, except that any reacquisition or repurchase rights held by the Company with respect to such stock awards will not terminate and may continue to be exercised notwithstanding the corporate transaction.

In the event a stock award will terminate if not exercised prior to the effective time of a corporate transaction, the Plan Administrator may provide, in its sole discretion, that the holder of such stock award may not exercise such stock award but instead will receive a payment equal in value to the excess (if any) of (i) value of the property that Participant would have received upon the exercise of the award, over (ii) any per share exercise price payable by such holder, if applicable. In addition, any escrow, holdback, earn out or similar provisions in the definitive agreement for the corporate transaction may apply to such payment to the same extent and in the same manner as such provisions apply to the holders of Common Stock.

Change in Control. Awards granted under the 2022 Equity Incentive Plan may be subject to acceleration of vesting and exercisability upon or after a change in control (as defined in the 2022 Equity Incentive Plan) as may be provided in the applicable stock award agreement or in any other written agreement between the Company or any affiliate and the participant, but in the absence of such provision, no such acceleration will automatically occur.

Clawback and Recoupment. Any award granted under the 2022 Equity Incentive Plan is subject to any clawback, recoupment or similar policy adopted by the Company, or as otherwise required by applicable laws.

Term

Awards under the 2022 Equity Incentive Plan may not be made after February 16, 2032, but awards granted prior to such date may extend beyond that date

The terms of each stock option shall be decided by the Plan Administrator provided that no stock options shall be exercisable more than ten years after the date such stock option is granted (or in the case of an incentive stock option granted to a 10% stockholder, no more than five years after the date such stock option is granted.)

Amendment and Termination

Subject to the rules referred to in the balance of this paragraph, our Board may, without stockholder approval, at any time amend, in whole or in part, any or all of the provisions of the 2022 Equity Incentive Plan, or suspend or terminate it entirely, retroactively or otherwise. Except as required to comply with applicable law, no such amendment may materially reduce the rights of a participant with respect to awards previously granted without the consent of such participant.

United States Federal Income Tax Consequences

The following discussion of the principal U.S. federal income tax consequences with respect to stock options granted under the 2022 Equity Incentive Plan is based on statutory authority and judicial and administrative interpretations as of the date of this proxy statement, which are subject to change at any time (possibly with retroactive effect) and may vary in individual circumstances. The discussion is limited to the U.S. federal income tax consequences (state, local and other tax consequences are not addressed below) to individuals who are citizens or residents of the U.S., other than those individuals who are taxed on a residence basis in a foreign country. In addition, the following discussion does not set forth any gift, estate, social security or state or local tax consequences that may be applicable.

The U.S. federal income tax law is technical and complex and the discussion below represents only a general summary. The following summary is included for general information only and does not purport to address all the tax considerations that may be relevant. Each recipient of a grant is urged to consult his or her own tax advisor as to the specific tax consequences to such grantee and the disposition of Common Stock.

Incentive Stock Options. The grant or exercise of an ISO generally has no income tax consequences for the optionee or the Company. No taxable income results to the optionee upon the grant or exercise of an ISO. However, the amount by which the fair market value of the stock acquired pursuant to the exercise of an ISO exceeds the exercise price is an adjustment item and will be considered income for purposes of alternative minimum tax.

The aggregate fair market value of Common Stock (determined at the time of grant) with respect to which ISOs can be exercisable for the first time by an optionee during any calendar year cannot exceed $100,000. In such case, the ISOs will be treated as a non-qualified stock option.

The sale of Common Stock received pursuant to the exercise of an option that satisfied all of the ISO requirements, as well as the holding period requirement described below, will result in a long-term capital gain or loss equal to the difference between the amount realized on the sale and the exercise price. To receive ISO treatment, an optionee must be an employee of the Company (or certain affiliates) at all times during the period beginning on the date of the grant of the ISO and ending on the day three months before the date of exercise, and the optionee must not dispose of the Common Stock purchased pursuant to the exercise of an option either (i) within two years from the date the ISO was granted, or (ii) within one year from the date of exercise of the ISO. Any gain or loss realized upon a subsequent disposition of the shares of Common Stock will be treated as a long-term capital gain or loss to the optionee (depending on the applicable holding period). The Company will not be entitled to a tax deduction upon such exercise of an ISO, or upon a subsequent disposition of the shares of Common Stock, unless such disposition occurs prior to the expiration of the holding period described above.

In general, if the optionee does not satisfy the foregoing holding periods, any gain (in an amount equal to the lesser of the fair market value of the Common Stock on the date of exercise (or, with respect to officers subject to Section 16(b) of the Exchange Act, the date that sale of such Common Stock would not create liability, referred to as Section 16(b) liability, under Section 16(b) of the Exchange Act) minus the exercise price, or the amount realized on the disposition minus the exercise price) will constitute ordinary income. In the event of such a disposition before the expiration of the holding periods described above, subject to the limitations under Code Sections 162(m) and 280G, the Company is generally entitled to a deduction at that time equal to the amount of ordinary income recognized by the optionee. Any gain in excess of the amount recognized by the optionee as ordinary income would be taxed to the optionee as short-term or long-term capital gain (depending on the applicable holding period).

Non-Qualified Stock Options. In general, an optionee will realize no taxable income upon the grant of an NSO and the Company will not receive a deduction at the time of such grant unless the option has a readily ascertainable fair market value (as determined under applicable tax law) at the time of grant. Upon exercise of an NSO, an optionee generally will recognize ordinary income in an amount equal to the excess of the fair market value of the stock on the date of exercise over the exercise price. Upon a subsequent sale of the stock by the optionee, the optionee will recognize short-term or long-term capital gain or loss depending upon his or her holding period for the stock. Subject to the limitations under Code Sections 162(m) and 280G, the Company will generally be allowed a deduction equal to the amount recognized by the optionee as ordinary income.

TABLE OF CONTENTS

Restricted Stock. Unless a participant makes an election to accelerate the recognition of income to the grant date (as described below), the grant of restricted stock or performance share awards will not result in taxable income to the participant. When the restrictions lapse, the participant will recognize ordinary income on the excess of the fair market value of the shares on the vesting date over the amount paid for the shares, if any, and the Company will be entitled to a corresponding deduction, subject to limitations under Code Sections 162(m) and 280G. If the participant makes an election under Section 83(b) of the Code within thirty days after the grant date, the participant will recognize ordinary income as of the grant date equal to the fair market value of the shares on the grant date over the amount paid, if any, and the Company will be entitled to a corresponding deduction. Any future appreciation will be taxed at capital gains rates. However, if the shares are later forfeited, the participant will not be able to recover any taxes paid.

RSUs. The grant of an RSU or performance restricted stock unit (PSU) will not result in taxable income to the participant. When the RSU is settled, the participant will recognize ordinary income equal to the fair market value of the shares or the cash provided on settlement and the Company will be entitled to a corresponding deduction, subject to the limitations under Code Sections 162(m) and 280G. Any future appreciation will be taxed at capital gains rates.

Code Section 162(m). Compensation of persons who are “covered employees” of the Company is subject to the tax deduction limits of Section 162(m) of the Code. The exemption from Section 162(m)’s deduction limit for performance-based compensation was repealed, effective for taxable years beginning after December 31, 2017, such that compensation paid to our covered employees in excess of $1 million will not be deductible.

Parachute Payments. In the event that the payment or vesting of any award under the 2022 Equity Incentive Plan is accelerated because of a change in ownership (as defined in Code Section 280G(b)(2)) and such payment of an award, either alone or together with any other payments made to certain participants, constitute parachute payments under Code Section 280G, then subject to certain exceptions, a portion of such payments would be nondeductible to the Company and the participant would be subject to a 20% excise tax on such portion of the payment.

Code Section 409A. Code Section 409A provides that all amounts deferred under a nonqualified deferred compensation plan are includible in a participant’s gross income to the extent such amounts are not subject to a substantial risk of forfeiture, unless certain requirements are satisfied. If the requirements are not satisfied, in addition to current income inclusion, interest at the underpayment rate plus 1% will be imposed on the participant’s underpayments that would have occurred had the deferred compensation been includible in gross income for the taxable year in which first deferred or, if later, the first taxable year in which such deferred compensation is not subject to a substantial risk of forfeiture. The amount required to be included in income is also subject to an additional 20% tax. While most awards under the 2022 Equity Incentive Plan are anticipated to be exempt from the requirements of Code Section 409A, awards that are not exempt are intended to comply with Code Section 409A.

New Plan Benefits

Under the 2022 Equity Incentive Plan, the terms and number of options or other awards to be granted in the future are to be determined in the discretion of the Plan Administrator.

TABLE OF CONTENTS

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS
AND MANAGEMENT

The following table sets forth certain information regarding the ownership of our Common Stock as of October 1, 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 October 1, 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 Solana Company (f/k/a Helius Medical Technologies, Inc.), 642 Newtown Yardley Road, Suite 100, Newtown, Pennsylvania 18940. As of October 1, 2025, we had 40,299,220 shares of Common Stock outstanding.

ADDITIONAL MATTERS

Other Matters

The Company is unaware of any business, other than as described in this proxy statement, that may be considered at the Special Meeting. If any other matters should properly come before the Special Meeting, it is the intention of the persons named in the accompanying form of proxy to vote the proxies held by them in accordance with their best judgment.

To assure the presence of the necessary quorum and to vote on the matters to come before the Special Meeting, please promptly indicate your choices via the internet or phone, or by mail, according to the procedures described on the proxy card. Voting before the Special Meeting does not prevent you from attending and voting at the Special Meeting.

Householding

The SEC has adopted rules that permit companies and intermediaries (such as brokers) to implement a delivery procedure called “householding.” Under this procedure, stockholders sharing an address who have been previously notified by their broker, bank or other agent and have consented to householding will receive only one copy of our proxy statement. This procedure reduces printing costs and postage fees, and helps protect the environment as well.

We expect that a number of brokers with account holders who are our stockholders will be “householding” our proxy materials. A single set of proxy materials will be delivered to multiple stockholders sharing an address unless contrary instructions have been received from one or more of the affected stockholders. Once you have received notice from your broker that it will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. Stockholders may revoke their consent at any time by contacting their broker.

Upon written or oral request, we will promptly deliver a separate copy of the proxy materials to any stockholder at a shared address to which a single copy of any of those documents was delivered. To receive a separate copy of the proxy materials, you may write our Secretary at 642 Newtown Yardley Road, Suite 100, Newtown, Pennsylvania 18940, (215) 431-3296. Any stockholders who share the same address and currently receive multiple copies of the proxy materials who wish to receive only one copy in the future can contact their bank, broker or other holder of record or our Corporate Secretary to request information about “householding”.

Requirements for Submission of Stockholder Proposals and Nominations for 2026 Annual Meeting

To be considered for inclusion in the proxy materials for our 2026 annual meeting of stockholders pursuant to Rule 14a-8 of the Exchange Act, your proposal must be submitted in writing by November 25, 2025, to our Corporate Secretary at Solana Company (f/k/a Helius Medical Technologies, Inc.), 642 Newtown Yardley Road, Suite 100, Newtown, Pennsylvania 18940.

TABLE OF CONTENTS

Any stockholder director nomination or proposal of other business intended to be presented for consideration at the 2026 annual meeting, but not intended to be considered for inclusion in our proxy statement and form of proxy relating to such meeting (i.e. not pursuant to Rule 14a-8 of the Exchange Act), must be received by us at the address stated above between December 22, 2025 and January 21, 2026. However, if our 2026 annual meeting occurs more than 30 days before or more than 30 days after April 21, 2026, we must receive nominations or proposals (i) not later than the close of business on the later of the 90th day prior to the date of the 2026 annual meeting or the 10th day following the day on which public announcement is made of the date of the 2026 annual meeting, and (ii) not earlier than the 120th day prior to the 2026 annual meeting.

The above-mentioned proposals and notice to the Corporate Secretary must also be in compliance with the Bylaws (including the information requirements therein) and the proxy solicitation rules of the SEC and Nasdaq as applicable. As such, stockholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must comply with the additional requirements of Rule 14a-19 under the Exchange Act including providing notice that sets forth the information required by not earlier than the close of business on December 22, 2025 and not later than the close of business on January 21, 2026. We reserve the right to reject, rule out of order or take other appropriate action with respect to any proposal that does not comply with the foregoing and other applicable requirements.

Solicitation by Board; Expenses

The Board is sending you this proxy statement in connection with the solicitation of proxies for use at the Special Meeting. We have engaged Saratoga Proxy Consulting LLC to assist in the solicitation of proxies and provide related advice and informational support, for a services fee, plus customary disbursements, which are not expected to exceed $20,000 in total. The Company’s directors, officers and regular employees may solicit proxies personally, telephonically, electronically or by other means of communication, but they will not receive any additional compensation for these services. The Company will pay the cost of preparing, assembling, and mailing the proxy materials. The Company has requested brokers, banks and other nominees to send the proxy materials to, and to obtain proxies from, the beneficial owners and the Company will reimburse such record holders for their reasonable expenses in doing so.

Your cooperation in giving this matter your immediate attention and in voting your proxies promptly is appreciated.

By Order of the Board of Directors,
