PROPOSAL 4 - APPROVAL OF A PROPOSED AMENDMENT TO OUR CERTIFICATE OF

INCORPORATION TO EFFECT A REVERSE SPLIT OF OUR OUTSTANDING COMMON STOCK TO

ENABLE THE COMPANY TO COMPLY WITH THE NASDAQ STOCK MARKET’S CONTINUED

LISTING REQUIREMENTS

General

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

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

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

Reasons for the Reverse Stock Split

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

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

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

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

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

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

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

Determination of the Reverse Stock Split Ratio

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

Impact of the Reverse Stock Split, if Implemented

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

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

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

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

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

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

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

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

Anti-Takeover and Dilutive Effects

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

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

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

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

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

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

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

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

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

If we cease to be eligible to trade on Nasdaq:

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

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

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

Procedure for Effecting the Reverse Stock Split

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

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

Exchange of Stock Certificates

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

Treatment of Fractional Shares

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

No Appraisal Rights

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

Material Federal Income Tax Consequences

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

possibly with retroactive effect. The Company has not sought and will not seek an opinion of counsel or a ruling from the Internal Revenue Service regarding the U.S. federal income tax consequences of the reverse stock split.

This discussion addresses the U.S. federal income tax consequences only to a stockholder that is (i) a citizen or individual resident of the United States, (ii) a corporation organized in or under the laws of the United States or any state thereof or the District of Columbia or otherwise subject to U.S. federal income taxation on a net income basis in respect of our Common Stock, (iii) a trust if (1) a U.S. court is able to exercise primary supervision over administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) it has a valid election in place to be treated as a U.S. person, or (iv) an estate whose income is subject to U.S. federal income taxation regardless of its source. This discussion addresses only those stockholders who hold their pre-reverse stock split shares as “capital assets” as defined in the Code (generally, property held for investment), and will hold the shares received in the reverse stock split as capital assets. Further, it does not address any state, local, foreign or other income tax consequences, nor does it address the tax consequences to stockholders that are subject to special tax rules, such as, without limitation, stockholders who are subject to the alternative minimum tax, banks, insurance companies, regulated investment companies, personal holding companies, stockholders who are not “United States persons” as defined in Section 7701(a)(30) of the Code, U.S. persons whose functional currency is not the U.S. dollar, broker-dealers, tax-exempt entities, or S corporations, partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes (or investors therein). If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds pre-reverse stock split shares of the Company’s stock, the U.S. federal income tax treatment of a partner of the partnership will depend on the status of the partner and the activities of the partnership and upon certain determinations made at the partnership level. Partners in partnerships holding our Common Stock are urged to consult their own tax advisors about the U.S. federal income tax consequences of the reverse stock split.

Stockholders are advised to consult their own tax advisers regarding the U.S. federal income tax consequences of the reverse stock split in light of their personal circumstances and the consequences under state, local and foreign tax laws, and also as to any estate or gift tax considerations.

Exchange Pursuant to Reverse Stock Split

No gain or loss will be recognized by a stockholder upon such stockholder’s exchange of pre-reverse stock split shares for post-reverse stock split shares pursuant to the reverse stock split, except to the extent of cash, if any, received in lieu of fractional shares, further described in “—Cash in Lieu of Fractional Shares” below. The aggregate tax basis of the post-reverse stock split shares received in the reverse stock split, including any fractional share deemed to have been received, will be equal to the aggregate tax basis of the pre-reverse stock split shares exchanged therefor, and the holding period of the post-reverse stock split shares will include the holding period of the pre-reverse stock split shares.

Cash in Lieu of Fractional Shares

A stockholder who receives cash in lieu of a fractional post-reverse stock split share should generally be treated as having received such fractional share pursuant to the reverse stock split and then as having exchanged such fractional share for cash in a redemption of such fractional share. The amount of any gain or loss should be equal to the difference between the ratable portion of the tax basis of the pre-reverse stock split shares exchanged in the reverse stock split that is allocated to such fractional share and the cash received in lieu thereof. In general, any such gain or loss will constitute a long-term capital gain or loss if the stockholder’s holding period for such pre-reverse stock split shares exceeds one year at the time of the reverse stock split. Deductibility of capital losses by holders is subject to limitations. Depending on a stockholder’s individual facts and circumstances, it is possible that cash received in lieu of a fractional share could be treated as a distribution under Section 301 of the Code, so stockholders should consult their own tax advisors as to that possibility and the resulting tax consequences to them in that event. The Company will not recognize any gain or loss as a result of the reverse stock split.

Vote Required

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

OUR BOARD UNANIMOUSLY RECOMMENDS A VOTE OF “FOR” PROPOSAL 4.
