The Annual Meeting will be held virtually via a live webcast by visiting www.virtualshareholdermeeting.com/SLNH2025, or at such other time and place to which the Annual Meeting may be adjourned or postponed. In order to attend our Annual Meeting, you must log in to the Annual Meeting at www.virtualshareholdermeeting.com/SLNH2025 using the 16-digit control number provided to you on the proxy card that accompanied the proxy materials. In addition, unless the context otherwise requires, references to "stockholders" of record are to the holders of our common stock, par value $0.001 per share (the "common stock"), and holders of record of our Series B Convertible Preferred Stock, par value $0.001 per share ("Series B Preferred Stock"), on July 9, 2025 (the "Record Date"). We refer to our common stock and our Series B Preferred Stock collectively from time to time in this Proxy Statement as "Voting Capital Stock." Stockholders attending the virtual meeting will be afforded the same rights and opportunities to participate in the Annual Meeting as they would be afforded at an in-person meeting.

Proxies for the Annual Meeting are being solicited by the Board of Directors (the "Board") of the Company. This Proxy Statement is first being made available to stockholders on or about &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; , 2025.

**Important Notice Regarding the Availability of Proxy Materials for the Stockholder Meeting To Be Held on August 18, 2025:**

**Our proxy materials including the Proxy Statement for the Annual Meeting, our annual report for the fiscal year ended December 31, 2024 and proxy card are available on the Internet at www.proxyvote.com. Under Securities and Exchange Commission (the "SEC") rules, we are providing access to our proxy materials by notifying you of the availability of our proxy materials on the Internet.**

**ABOUT THE MEETING**

**Why are we calling this Annual Meeting?**

We are calling the Annual Meeting to seek the approval of our stockholders:

● To elect David Michaels and Matthew Lipman to serve as Class II directors each for a three-year term expiring at the annual meeting of stockholders in 2028 (the "Director Proposal");

● To approve one or more reverse stock splits of the then-outstanding shares of our common stock, with no change to the number of authorized shares of common stock of the Company, having an aggregate ratio of not less than one-for-five (1:5) and not greater than one-for-fifty (1:50) (each a "Reverse Stock Split" and, collectively, the "Reverse Stock Splits"), with the exact number, timing, and ratio within such aggregate range each to be determined by our Board in its discretion and included in a public announcement, to be effectuated at any time within one year after stockholder approval has been obtained (the "Reverse Stock Split Proposal");

● To approve the adjournment of the Annual Meeting in the event that the number of shares of the Company's Voting Capital Stock present or represented by proxy at the Annual Meeting and voting "FOR" the approval of the Reverse Stock Split Proposal is insufficient to approve such proposal (the "Adjournment Proposal");

● To ratify the appointment of UHY LLP as our independent registered public accounting firm for the year ending December 31, 2025 (the "Auditor Proposal"); and

● To consider any other matters that may properly come before the Annual Meeting, including any adjournment or postponement thereof.

**What are the Board's recommendations?**

Our Board believes that (A) the election of David Michaels and Matthew Lipman as Class II directors, (B) the Reverse Stock Split Proposal, (C) the Adjournment Proposal, and (D) the Auditor Proposal, are each advisable and in the best interests of the Company and its stockholders and recommends that you vote **FOR** each of the director nominees and **FOR** each of the foregoing proposals. If you are a stockholder of record and you return a properly executed proxy card or submit a proxy to vote over the Internet but do not mark the boxes showing how you wish to vote, your shares will be voted in accordance with the recommendations of the Board, as set forth above. With respect to any other matter that properly comes before our Annual Meeting, the proxy holders will vote as recommended by the Board or, if no recommendation is given, at their own discretion.

**Who is entitled to vote at the meeting?**

Only holders of record of our Voting Capital Stock outstanding at the close of business on the Record Date, are entitled to receive notice of the Annual Meeting and to vote the shares of Voting Capital Stock that they held on that date at the Annual Meeting or any postponement or adjournment of the Annual Meeting, subject to, in the case of Series B Preferred Stock only, the Beneficial Ownership Limitation (the "Beneficial Ownership Limitation") set forth in the Certificate of Designation of Preferences, Rights and Limitations of the Series B Convertible Preferred Stock (the "Certificate of Designation for the Series B Preferred Stock"). Holders of record of the Voting Capital Stock have the right to vote on all matters brought before the Annual Meeting.

Holders of our common stock are entitled to one vote per share on each matter to be voted upon. Holders of our Series B Preferred Stock are entitled to one vote per share of common stock deemed issuable upon the conversion of our Series B Preferred Stock, subject to the Beneficial Ownership Limitation, on each matter to be voted upon. As of the Record Date, we had &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; shares of common stock outstanding and &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; shares of common stock deemed issuable upon the conversion of the Series B Preferred Stock and entitled to vote at the Annual Meeting (equal to 4.99% of the number of shares of our common stock outstanding immediately after giving effect to the issuance of the shares of common stock issuable upon conversion of the Series B Preferred Stock held by the holder thereof).

**Who can attend the meeting?**

All stockholders as of the Record Date, or their duly appointed proxies, may attend the Annual Meeting. Attendance at the Annual Meeting shall solely be via the Internet at www.virtualshareholdermeeting.com/SLNH2025 using the 16-digit control number on the proxy card that accompanied the proxy materials. Stockholders will not be able to attend the Annual Meeting at a physical location.

The live webcast of the Annual Meeting will begin promptly at 10:00 am Eastern Time on August 18, 2025. Online access to the webcast will open approximately 15 minutes prior to the start of the Annual Meeting to allow time for our stockholders to log in and test their devices' audio system. We encourage our stockholders to access the Annual Meeting in advance of the designated start time.

An online portal will be available to our stockholders at www.proxyvote.com commencing approximately on or about July 16, 2025. By accessing this portal, stockholders will be able to submit a proxy to vote in advance of the Annual Meeting. Stockholders may also vote, and submit questions, during the Annual Meeting at www.virtualshareholdermeeting.com/SLNH2025. To demonstrate proof of stock ownership, you will need to enter the 16-digit control number received with your proxy card to submit questions and vote at our Annual Meeting. If you hold your shares in "street name" (that is, through a broker or other nominee), you will need authorization from your broker or nominee in order to vote. We intend to answer questions submitted during the Annual Meeting that are pertinent to the Company and the items being brought for stockholder vote at the Annual Meeting, as time permits, and in accordance with the Rules of Conduct for the Annual Meeting. We have retained Broadridge Financial Solutions to host our virtual Annual Meeting and to distribute proxies and receive, count and tabulate votes.

**What constitutes a quorum?**

The presence at the Annual Meeting, in person or by proxy, of at least thirty-three and one-third percent of the voting power of all issued and outstanding shares of our capital stock entitled to vote at the Annual Meeting will constitute a quorum for the Annual Meeting. Abstentions and broker non-votes, if any, will be counted for the purpose of determining whether a quorum is present.

**How do I vote or submit a proxy to vote?**

You may submit your proxy to vote on the Internet, by telephone, by mail or may vote by attending the Annual Meeting and voting electronically, all as described below. The Internet and telephone proxy submission procedures are designed to authenticate stockholders by use of a control number and to allow you to confirm that your instructions have been properly recorded. If you vote by telephone or on the Internet, you do not need to return your proxy card or voting instruction card.

***Submit a Proxy to Vote on the Internet***

 ****

If you are a stockholder of record, you may submit your proxy by going to www.proxyvote.com, and following the instructions provided in the proxy card that accompanied the proxy materials. If your shares are held with a broker, you will need to go to the website provided on your proxy card. Have your proxy card in hand when you access the voting website. On the Internet voting site, you can confirm that your instructions have been properly recorded. If you submit a proxy to vote on the Internet, you can also request electronic delivery of future proxy materials. **Internet voting facilities are available now and will be available 24 hours a day until 11:59 p.m., Eastern Time, on August 17, 2025.**

***Submit a Proxy to Vote by Telephone***

If you are a stockholder of record, you can also submit a proxy to vote by telephone by dialing 1-800-690-6903. If your shares are held with a broker, you can submit a proxy to vote by telephone by dialing the number specified on your voting instruction card. Have your proxy card or voting instruction card in hand when you call. Telephone voting facilities are available now and will be available 24 hours a day until **11:59 p.m., Eastern Time, on August 17, 2025.**

***Submit a Proxy to Vote by Mail***

You may choose to submit a proxy to vote by mail, by marking your proxy card or voting instruction card, dating and signing it, and returning it in the postage-paid envelope provided. If the envelope is missing and you are a stockholder of record, please mail your completed proxy card to Vote Processing, c/o Broadridge, 51 Mercedes Way, Edgewood, NY 11717. If the envelope is missing and your shares are held with a broker, please mail your completed voting instruction card to the address specified therein. Please allow sufficient time for mailing if you decide to submit a proxy to vote by mail as it must be received by **11:59 p.m., Eastern Time, on August 17, 2025**.

***Vote at the Annual Meeting***

You will have the right to vote on the day of, or during, the Annual Meeting on www.virtualshareholdermeeting.com/SLNH2025. To demonstrate proof of stock ownership, you will need to enter the 16-digit control number received with your proxy card to vote at our Annual Meeting.

Even if you plan to attend our Annual Meeting, we recommend that you also submit your proxy as described above so that your vote will be counted if you later decide not to attend our Annual Meeting.

The proxies to vote that are submitted electronically, telephonically or represented by the proxy cards received, properly marked, dated, signed and not revoked, will be voted at the Annual Meeting.

**What if I vote and then change my mind?**

You may revoke your proxy at any time before it is exercised by:

● filing with the Secretary of the Company a notice of revocation;

● submitting a later-dated proxy to vote by telephone or on the Internet;

● sending in another duly executed proxy bearing a later date; or

● attending the Annual Meeting remotely and casting your vote in the manner set forth above.

Your latest proxy or vote will be the vote that is counted.

**What is the difference between holding shares as a stockholder of record and as a beneficial owner?**

Many of our stockholders hold their shares through a stockbroker, bank or other nominee rather than directly in their own name. As summarized below, there are some distinctions between shares held of record and those owned beneficially.

**Stockholder of Record**

If your shares are registered directly in your name with our transfer agent, Equiniti Trust Company LLC, you are considered, with respect to those shares, the stockholder of record. As the stockholder of record, you have the right to directly grant your voting proxy or to vote at the Annual Meeting.

**Beneficial Owner**

If your shares are held in a stock brokerage account or by a bank or other nominee, you are considered the beneficial owner of shares held in street name, and these proxy materials are being forwarded to you by your broker, bank or nominee which is considered, with respect to those shares, the stockholder of record. As the beneficial owner, you have the right to direct your broker as to how to vote and are also invited to attend the Annual Meeting. However, because you are not the stockholder of record, you may not vote these shares unless you obtain a signed proxy from the record holder giving you the right to vote the shares. If you do not provide the stockholder of record with voting instructions or otherwise obtain a signed proxy from the record holder giving you the right to vote the shares, broker non-votes may occur for the shares that you beneficially own. The effect of broker non-votes is more specifically described in "*What vote is required to approve each proposal?*" below.

**What vote is required to approve each proposal?**

Assuming that a quorum is present, the following votes will be required to approve each proposal:

● With respect to the Director Proposal, directors are elected by a plurality of the votes cast by holders of our Voting Capital Stock, present in person or represented by proxy and entitled to vote on the election of directors. The director nominees who receive the greatest number of votes at the Annual Meeting (up to the total number of directors to be elected) will be elected. As a result, withheld votes and "broker non-votes" (see below), if any, will not affect the outcome of the vote on the Director Proposal. Consequently, only shares that are voted in favor of a particular nominee will be counted toward such nominee's achievement of a plurality. You may not vote your shares cumulatively for the election of directors.

● With respect to the Reverse Stock Split Proposal, the Adjournment Proposal, and the Auditor Proposal, as well as the approval of any other matter that may properly come before the Annual Meeting, the affirmative vote of the holders of a majority of the votes cast by holders of our Voting Capital Stock, present in person or represented by proxy, is required to approve these proposals. As a result, abstentions, broker non-votes, if any, and any other failure to submit a proxy or vote in person at the meeting, will not affect the outcome of the vote of the Reverse Stock Split Proposal, the Adjournment Proposal and the Auditor Proposal.

Under Nevada law, the Company's stockholders are not entitled to dissenter's or appraisal rights in connection with any of the proposals to be acted upon at the Annual Meeting.

**What are "broker non-votes"?**

Banks and brokers acting as nominees are permitted to use discretionary voting authority to vote proxies for proposals that are deemed "routine" by the New York Stock Exchange, which means that they can submit a proxy or cast a ballot on behalf of stockholders who do not provide a specific voting instruction. Brokers and banks are not permitted to use discretionary voting authority to vote proxies for proposals that are deemed "non-routine" by the New York Stock Exchange. The determination of which proposals are deemed "routine" versus "non-routine" may not be made by the New York Stock Exchange until after the date on which this Proxy Statement has been mailed to you. As such, it is important that you provide voting instructions to your bank, broker or other nominee, if you wish to ensure that your shares are present and voted at the Annual Meeting on all matters and if you wish to direct the voting of your shares on "routine" matters.

A broker non-vote occurs when there is at least one "routine" matter to be considered at a meeting and a broker submits a proxy to vote on at least one "routine" proposal but does not vote on a given proposal because the broker does not have discretionary power for that particular item and has not received instructions from the beneficial owner on that proposal.

Under the applicable rules governing such brokers, we believe the Reverse Stock Split Proposal, the Adjournment Proposal, and the Auditor Proposal are likely to be considered "routine" items. This means that brokers may vote using their discretion on such proposals on behalf of beneficial owners who have not furnished voting instructions. In contrast, certain items are considered "non-routine," and a "broker non-vote" occurs when brokers do not receive voting instructions from beneficial owners with respect to such items because the brokers are not entitled to vote such uninstructed shares. We believe the Director Proposal is likely to be considered "non-routine", which means that brokers cannot vote your uninstructed shares when they do not receive voting instructions from you.

**How are we soliciting this proxy?**

We are soliciting this proxy on behalf of our Board and will pay all expenses associated therewith. In the event that we need to adjourn the Annual Meeting to solicit additional votes, we may at that time retain a proxy solicitor at an additional cost to us. Some of our officers, directors and other employees also may, but without compensation other than their regular compensation, solicit proxies by further mailing or personal conversations, or by telephone, facsimile or other electronic means.

We will also, upon request, reimburse brokers and other persons holding stock in their names, or in the names of nominees, for their reasonable out-of-pocket expenses for forwarding proxy materials to the beneficial owners of the capital stock and to obtain proxies.

**PROPOSAL 1: TO ELECT TWO DIRECTORS AS CLASS II DIRECTORS TO SERVE**

**THREE-YEAR TERMS EXPIRING AT THE ANNUAL MEETING IN 2028 AND**

**UNTIL THEIR SUCCESSORS HAVE BEEN DULY ELECTED AND QUALIFIED**

Our Board presently has nine members. There are two directors in the class (Class II) whose term of office expire in 2025. The nominees listed below are currently directors of the Company. If elected at the Annual Meeting, such nominees would serve until our 2028 annual meeting and until their successors have been duly elected and qualified, or, if sooner, until their earlier resignation, death or removal.

Directors are elected by a plurality of the votes cast. Stockholders may not vote, or submit a proxy, for more than one nominee. The nominee receiving the highest number of affirmative votes will be elected. Unless otherwise directed, shares represented by executed proxies will be voted for the election of David Michaels and Matthew Lipman. If the director nominees become unavailable for election as a result of an unexpected occurrence, shares that would have been voted for the nominee will instead be voted for the election of substitute nominees proposed by our Board. The director nominees have agreed to serve if elected. Our management has no reason to believe that the director nominees will be unable to serve.

**Class II Nominees for Election for a Term Expiring at the 2028 Annual Meeting**

The following table sets forth the name, age and position and tenure of the individuals nominated for election as our Class II directors for terms expiring at the 2028 annual meeting:

---

| | | | |
|:---|:---|:---|:---|
| **Name** | **Age**<br>| **Position** | **Served as a Director Since**<br>|
| David Michaels | 70 | Director | 2013 |
| Matthew Lipman | 46 | Director | 2016 |

The following includes brief biographies of David Michaels and Matthew Lipman, based on information furnished to us by them, with such biography including information regarding the experiences, qualifications, attributes or skills that caused our Nominating and Corporate Governance Committee and the Board to determine that they should continue to serve as members of our Board.

**David C.

**CORPORATE GOVERNANCE**

**Board of Directors Composition**

Our Board is currently composed of nine directors. Our directors hold office until their successors have been elected and qualified or until the earlier of their resignation or removal.

We have no formal policy regarding board diversity. Our priority in selection of Board members is identification of members who will further the interests of our stockholders through their established record of professional accomplishment, the ability to contribute positively to the collaborative culture among Board members, knowledge of our business and understanding of the competitive landscape.

**Board of Directors Meetings**

Our Board met 26 times in 2024. Each director attended at least 75% of the aggregate of (i) the total number of meetings of our Board (held during the period for which such director served on the Board) and (ii) the total number of meetings of all committees of our Board on which such director served (during the periods for which the director served on such committee or committees). We do not have a formal policy requiring members of the Board to attend our annual meetings. Eight members of the Board attended our 2024 annual meeting of stockholders, which was held remotely.

**Director Independence**

Pursuant to the rules of Nasdaq, a director will only qualify as an "independent director" if, in the opinion of that company's board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Under such rules, the Board has determined that Messrs. Bottomley, Hazelip, Hirshfield, Michaels, Marusak, and Phelan are "independent directors," as defined by the rules and listing standards of Nasdaq. Messrs. Belizaire, Lipman and Toporek are not independent directors under the Nasdaq rules. In making such independence determinations, our Board considered the relationships that each non-employee director has with us and all other facts and circumstances that our Board deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. In considering the independence of the directors listed above, our Board considered the association of our directors with the holders of more than 5% of our common stock. There are no family relationships among any of our directors and executive officers.

**Board Of Directors Committees**

The Board has an Audit Committee, a Nominating and Corporate Governance Committee, a Compensation Committee, and an Executive Committee.

**Audit Committee**

The Board has adopted an Audit Committee charter, which is published on our website at https://www.solunacomputing.com/investors/governance/. The Audit Committee consists of Messrs. Marusak (Chair), Hirshfield, Phelan, and Bottomley.

The Audit Committee's primary function is to assist the Board in fulfilling its oversight responsibilities by reviewing the financial information to be provided to the stockholders and others, the system of internal controls which management has established and the audit and financial reporting process. The Audit Committee, among other matters, (1) is responsible for the annual appointment of, and for compensating, retaining, overseeing, ensuring independence of, and, where appropriate, replacing, the independent registered public accounting firm as the Company's auditors, (2) reviews the arrangements for and the results of the auditors' examination of our books and records, and (3) assists the Board in its oversight of the reliability and integrity of the Company's accounting policies, financial statements and financial reporting, and disclosure practices, including its system of internal controls, (4) the establishment and maintenance of processes to ensure compliance with all relevant laws, regulations, and Company policies, (5) is responsible for the Company's policies with respect to risk assessment and risk management pertaining to the financial, accounting and tax matters of the Company, and 6) reviews annually the adequacy of the charter of the Audit Committee and recommends changes to the Board that it considers necessary or appropriate.

**Compensation Committee**

The Board has adopted a Compensation Committee charter, which is published on our website at https://www. solunacomputing.com/investors/governance/. The Compensation Committee consists of Messrs. Phelan (Chairman), Hazelip, and Bottomley. The Board has determined that each member of the Compensation Committee is independent, as defined under the applicable rules and listing standards of Nasdaq and SEC rules and regulations.

The role of the Compensation Committee is to assist the Board by, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) reviewing and approving compensation programs, philosophy, and practices of the Company for service providers of the Company, particularly as it relates to its executive officers, key employees, and directors; (2) reviewing and evaluating annually the Company objectives and goals regarding our Chief Executive Officer's compensation and the approval or recommendation for approval to the Board of such compensation; (3) evaluating director compensation and making recommendations to the Board regarding such compensation; (4) annually evaluating the adequacy of the Compensation Committee charter and recommending any changes to the Board; (5) administering the Company's equity compensation plans; and (6) determining succession planning and management development for the Chief Executive Officer and other executive officers and key employees.

In fulfilling its responsibilities, the Compensation Committee may delegate any or all of its responsibilities to a subcommittee of the Compensation Committee and, to the extent not expressly reserved to the Compensation Committee by the Board or by applicable law, rule, or regulation, to any other committee of directors appointed by it.

The Compensation Committee administers our executive compensation programs. This Compensation Committee is responsible for establishing the policies that govern base salaries, as well as short- and long-term incentives, for executives and senior management. The Committee has approval authority regarding the compensation of the Company's Chief Executive Officer, as well as the Company's other executive officers and key employees.

**Nominating and Corporate Governance Committee**

The Board has adopted a Nominating and Corporate Governance Committee charter, which is published on our website at https://www.solunacomputing.com/investors/governance/.

Individuals recommended by stockholders are evaluated in the same manner as other potential candidates. A stockholder wishing to submit such a recommendation should forward it in writing to our Secretary at 325 Washington Avenue Extension, Albany, New York 12205. The mailing envelope should include a clear notation that the enclosure is a "Director Nominee Recommendation." The recommending party should be identified as a stockholder and should provide a brief summary of the recommended candidate's qualifications, taking into account the desired characteristics and qualifications considered for potential Board members mentioned above.

**Executive Committee**

The Board formed an Executive Committee in January 2022 and adopted an Executive Committee charter, which is published on our website at https://www.solunacomputing.com/investors/governance/. The Executive Committee as of the date of this report consists of Messrs. Phelan (Chairman), Bottomley, Lipman, and Toporek. The Board has determined that each of Mr. Phelan and Mr. Bottomley are independent, as defined under the applicable rules and listing standards of Nasdaq.

The Executive Committee met every other week for a total of 19 meetings in fiscal year 2024. The purpose of the Executive Committee is to represent and assist the Board in its review and approval of certain transactions and other matters requiring Board consideration, and to take action, where necessary, appropriate and authorized by the Board during intervals between regular and special meetings of the Board. The Executive Committee has authority to: 1) monitor management's performance against the approved budget of record; 2) authorize mining equipment purchase transactions; 3) authorize the price at which equity securities of the Company are sold; 4) authorize the payment of dividends to holders of preferred stock of the Company; and 5) identify and assess business risks and develop and propose recommendations to management and the Board to minimize such risks. Notwithstanding anything in the foregoing, the Executive Committee is not authorized to 1) take any action that requires an adoption by an independent majority of the Board; 2) complete any transaction that would have a material effect on the Company's financial statements; or 3) complete any transaction that qualifies as a related party transaction.

**Board Leadership Structure and Role in Risk Oversight**

The Board executes its oversight responsibility for risk management directly and through its Committees, as follows:

The Audit Committee has primary responsibility for overseeing the integrity of the Company's financial reporting risk by reviewing: (i) the Company's disclosure controls and procedures; (ii) any significant deficiencies in the design or operation of internal controls; (iii) any fraud material or otherwise; (iv) the use of judgments in management's preparation of the financial statements; and (v) through consultation with Company's independent registered public accounting firm on the above items. The Board is kept abreast of the Committee's risk oversight and other activities via reports of the Committee Chairman to the full Board.

The Compensation Committee oversees the risks associated with our compensation policies and practices, with respect to both executive compensation and compensation generally. The Board is kept abreast of the Committee's risk oversight and other activities via reports of the Committee Chairman to the full Board.

The Executive Committee is responsible for identifying and assessing business risks and proposing recommendations to management and the full Board. The Board is kept abreast of the Committee's risk oversight and other activities via reports of the Committee Chairman to the full Board.

The Board considers specific risk topics, including risks associated with our strategic plan, our capital structure, and our development activities. In addition, the Board receives detailed regular reports from the heads of our principal business and corporate functions that include discussions of the risks and exposures involved in their respective areas of responsibility. These reports are provided in connection with every regular Board meeting and are discussed, as necessary, at Board meetings. Further, the Board is routinely informed of developments at the Company that could affect our risk profile or other aspects of our business.

We do not believe that the Board's role in risk oversight has any impact on its leadership structure, as discussed below.

***Executive Sessions of Directors***

 

Executive sessions, or meetings of outside (non-management) directors without management present, are held periodically throughout the year. At these executive sessions, the outside directors review, among other things, the criteria upon which the performance of the Chief Executive Officer and other executive officers is based, the performance of the Chief Executive Officer against such criteria, and the compensation of the Chief Executive Officer and other executive officers. Meetings are held from time to time with the Chief Executive Officer to discuss relevant subjects.

***Board Leadership Structure***

 

The Board recognizes that one of its key responsibilities is to evaluate and determine its optimal leadership structure so as to provide independent oversight of management. The Board understands that there is no single, generally accepted approach to providing Board leadership and that given the dynamic and competitive environment in which we operate, the right Board leadership structure may vary as circumstances warrant. As of the date of this Proxy Statement, Michael Toporek serves as Executive Chairman of the Board and William Phelan serves as our Lead Independent Director. The Board recognizes that it is important to determine an optimal board leadership structure to ensure the independent oversight of management as the Company continues to grow. Michael Toporek had served as our Chief Executive Officer since October 2020, and effective May 1, 2023, John Belizaire began service as Chief Executive Officer and Michael Toporek serves as Executive Chairman. The Chief Executive Officer is responsible for setting the strategic direction for the Company and the day-to-day leadership and performance of the Company, while the Executive Chairman of the Board provides guidance to the Chief Executive Officer and presides over meetings of the full Board and the Lead Independent Director, coordinates the activities of the other independent directors and performs such other duties and responsibilities as the Board may determine. We believe that this separation of responsibilities also provides a balanced approach to managing the Board and overseeing the Company.

In considering its leadership structure, the Board has taken a number of factors into account. The Board, which consists of directors who are highly qualified and experienced, four of whom are independent directors, exercises a strong, independent oversight function. This oversight function is enhanced by the fact that the Board's three of the four standing committees – the Audit Committee, the Nominating and Corporate Governance Committee and the Compensation Committee – are comprised solely of independent directors and the Executive Committee, is comprised of a majority of independent directors.

**Stockholder Communications**

Stockholders who wish to communicate with the Board, or a particular director, may send a letter to our Secretary at 325 Washington Avenue Extension, Albany, New York 12205. The mailing envelope must contain a clear notation indicating that the enclosed letter is a "Stockholder-Board Communication." All such letters must identify the author as a stockholder and clearly state whether the intended recipients are all members of the Board or certain specified individual directors. The Secretary will make copies of all such letters and circulate them to the appropriate director or directors.

**Code of Business Conduct and Ethics**

We have adopted a written code of conduct and ethics that applies to our directors, officers, contractors, and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. A current copy of our code is posted on our website, which is located at www.solunacomputing.com. We intend to disclose future amendments to certain provisions of our code of conduct and ethics, or waivers of such provisions applicable to any principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, and our directors, on our website identified above or in filings with the SEC.

**Insider Trading Policy**

The Company has an insider trading policy governing the purchase, sale and other dispositions of the Company's securities that applies to all of the Company's directors, officers, and employees. The Company believes that its insider trading policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and listing standards applicable to the Company. A copy of the Company's insider trading policy is filed as Exhibit 19.1 to our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

**Anti-Hedging Policy**

Under the terms of our insider trading policy, we prohibit all Company personnel, including directors, officers, and employees, from engaging in certain forms of hedging transactions. Such transactions include those, such as puts and calls, and other derivative securities, that would allow them to lock in much of the value of their stock holdings, often in exchange for all or part of the potential for upside appreciation in the stock, and to continue to own the covered securities but without the full risks and rewards of ownership.

**Clawback Policy** 

The Board adopted a written policy to recover "excess" compensation that is granted, earned, or vested based wholly or in part upon the attainment of a financial reporting measure. The compensation includes both cash-based and equity-based incentives. The compensation covered includes incentive awards awarded to any individuals (including former employees) who served as an executive officer during the three most recently completed fiscal years preceding the date on which the preparation of an accounting restatement is required, provided that the executive officers were awarded more incentive awards than they would have received if the financial statements had been prepared correctly. The recovery will include an executive incentive award even if the executive was not involved in preparing the financial statements or did not commit misconduct that led to the restatement. Restatements attributable to an inadvertent error also will subject executive officers to the recovery of previously received incentive awards.

**Delinquent Section 16(a) Reports**

Section 16(a) of the Exchange Act requires our directors, executive officers and persons who beneficially own more than 10% of our outstanding common shares to file reports with the SEC regarding their share ownership and changes in their ownership of our common shares. Based on our records and representations from our directors and executive officers, we believe that all Section 16(a) filing requirements applicable to our directors and executive officers were complied with during the fiscal year ended December 31, 2024, except for the following: due to administrative error, Mr. Lipman and Mr. Toporek failed to timely file Form 4s on October 31, 2024, to report the disposition of 8,000 shares of common stock, on November 1, 2024, to report the disposition of 31,300 shares of common stock, and on November 4, 2024, to report the disposition of 20,600 shares of common stock.

**TRANSACTIONS WITH RELATED PERSONS**

The following is a description of transactions since January 1, 2023, and each currently proposed transaction in which:

● We have been or are to be a participant;

● the amount involved exceeded or will exceed the lesser of $120,000 or 1% of our total assets at year-end for our last two completed fiscal years; and

● any of our directors, executive officers or beneficial owners of more than 5% of our capital stock, or any immediate family member of, or person sharing the household with, any of these individuals or entities, had or will have a direct or indirect material interest, other than compensation and other arrangements that are described in the section titled "Executive Compensation."

***MeOH Power, Inc.***

On December 18, 2013, MeOH Power, Inc. ("MeOH") and the Company executed a Senior Demand Promissory Note (the "Note") in the amount of $380 thousand to secure the intercompany amounts due to the Company from MeOH upon the deconsolidation of MeOH. Interest accrues on the Note at the Prime Rate in effect on the first business day of the month, as published in the Wall Street Journal. At the Company's option, all or part of the principal and interest due on this Note may be converted to shares of common stock of MeOH at a rate of $0.07 per share. Interest began accruing on January 1, 2014. The Company recorded a full allowance against the Note. As of December 31, 2024 and December 31, 2023, $385 thousand and $363 thousand, respectively, of principal and interest are available to convert into shares of common stock of MeOH. Any adjustments to the allowance are recorded as miscellaneous expenses during the period incurred.

***HEL Transactions***

On October 29, 2021, the Company completed the Soluna Callisto acquisition pursuant to a merger agreement (the "Merger Agreement"). The purpose of the transaction was for SCI to acquire substantially all of the assets (other than those assets physically located in Morocco) formerly held by Harmattan Energy, Ltd. (formerly Soluna Technologies, Ltd.) ("HEL"), which assets consisted of SCI's existing pipeline of certain cryptocurrency mining projects that HEL previously transferred to SCI, which was formed expressly for this purpose, and to provide SCI with the opportunity to directly employ or retain the services of four individuals whose services it had retained through HEL prior to the merger. As a result of the merger, each share of common stock of Soluna Callisto issued and outstanding immediately prior to the effective time of the merger, other than shares owned by the Company or any of our subsidiaries, was canceled and converted into the right to receive a proportionate share of up to 118,800 shares (the "Merger Shares") of Mechanical Technology, Incorporated common stock, payable upon the achievement of certain milestones.

Due to conditions being met within the Merger Agreement in relation to energization and retention of employees, the Company has advised SCI US Holdings LLC, a Delaware limited liability company, who is the sole Effective Time Holder (as defined in the Merger Agreement) of the right to receive the Merger Shares and that 19,800 Merger Shares were issued on April 19, 2024 and 39,600 Merger Shares were issued on October 10, 2023. SCI US Holdings LLC has consented to the issuance of such Merger Shares as required under the Merger Agreement and has directed the Company to issue such Merger Shares to its affiliate, HEL. Following the issuance of the 59,400 Merger Shares, a total of 59,400 Merger Shares remain available for possible issuance pursuant to the terms of the Merger Agreement.

Several of HEL's equity holders are affiliated with Brookstone Partners, the investment firm that holds an equity interest in the Company through Brookstone XXIV. The Company's two Brookstone-affiliated directors also serve as directors and, in one case, as an officer, of HEL and also have ownership interest in HEL. In light of these relationships, the various transactions by and between the Company and SCI, on the one hand, and HEL, on the other hand, were negotiated on behalf of the Company and SCI via an independent investment committee of the Board and separate legal representation. The transactions were subsequently unanimously approved by both the independent investment committee and the full Board.

Four of the Company's directors have various affiliations with HEL.

Michael Toporek, the former Chief Executive Officer, and current Executive Director of the Company, owns (i) 90% of the equity of Soluna Technologies Investment I, LLC, which owns 57.9% of HEL and (ii) 100% of the equity of MJT Park Investors, Inc., which owns 3.1% of HEL, in each case, on a fully diluted basis. Mr. Toporek does not own directly, or indirectly, any equity interest in Tera Joule, LLC ("Tera Joule"), which owns 9.2% of HEL; however, as a result of his 100% ownership of Brookstone IAC, Inc. ("Brookstone IAC"), which is the manager of Tera Joule, he has dispositive power over the equity interests that Tera Joule owns in HEL.

In addition, one of the Company's directors, Matthew E. Lipman, serves as a director and is currently acting as President of HEL. Mr. Lipman does not directly own any equity interest in Tera Joule, which owns 9.2% of HEL; however, as a result of his position as a director and officer of Brookstone IAC, which is the manager of Tera Joule, he has dispositive power over the equity interests that Tera Joule owns in HEL. As a result, the approximate dollar value of the amount of Mr. Toporek's and Mr. Lipman's interest in the Company's transactions with HEL for the year ended December 31, 2024 was $0 and $0.

John Belizaire, the Company's Chief Executive Officer, and John Bottomley, who were elected to the Board upon the effective time of SCI's acquisition of Soluna Callisto, serve as directors of HEL. In addition, Mr. Belizaire is the beneficial owner of 1,317,567 shares of common stock of HEL and 102,380 Class Seed Preferred shares, which are convertible into 86,763 shares of common stock of HEL. These interests give Mr. Belizaire an ownership of 10.54% in HEL. Mr. Belizaire also owns an interest in HEL indirectly through his 5.0139% interest of Tera Joule's 965,945 Class Seed Preferred shares, which are convertible into 818,596 shares of common stock of HEL. Mr. Bottomley is the beneficial owner of 96,189, or approximately 0.72%, of the outstanding shares of common stock of HEL.

The Company's investment in HEL was initially carried at the cost of investment and was $750 thousand. Based on evaluation of projections for the Company's investment in HEL, the Company fully impaired the equity investment of $750 thousand as of December 31, 2022, writing it down to $0.

The Company owned approximately 1.79% of HEL, calculated on a converted fully diluted basis, as of December 31, 2024 and December 31, 2023. The Company may enter into additional transactions with HEL in the future.

***Yorkville SEPA***

YA entered into the SEPA with the Company on August 12, 2024. Under the SEPA, the Company has the option to sell up to $25 million of common stock to YA, and YA is obligated to purchase such shares, at a price and on the terms and subject to the conditions set forth in the SEPA. YA beneficially owns more than 5% of our capital stock.

**Policies and Procedures for Related Party Transactions**

We have adopted a written policy requiring that all related person transactions be reported to our executive management and/or the Board and approved or ratified by the Audit Committee. In completing its review of proposed related person transactions, the Audit Committee considers the aggregate value of the transaction, whether the transaction was undertaken in the ordinary course of business, the nature of the relationships involved, and whether the transaction is on terms comparable to those that could be obtained in arm's length dealings with an unrelated third party.

**PROPOSAL 2: APPROVAL OF THE REVERSE STOCK SPLIT PROPOSAL**

**General**

On July 3, 2025, the Board unanimously adopted resolutions approving, declaring advisable and recommending to our stockholders for their approval of the effectuation of one or more Reverse Stock Splits pursuant to Nevada Revised Statutes ("NRS") 78.2055, with an aggregate ratio in the range of not less than one-for-five (1:5) and not greater than one-for-fifty (1:50), with the number, timing and exact ratio each to be determined by our Board in its discretion at any time within one year after stockholder approval is obtained, to regain compliance with the $1.00 minimum bid price continued listing requirement), with respect to the then-issued and outstanding shares of our common stock. Each Reverse Stock Split will also affect then-outstanding options, warrants and Series B Preferred Stock. A Reverse Stock Split will not affect the number of our authorized shares of common stock.

Approval of this proposal will grant our Board the authority, without further action by our stockholders, to carry out one or more Reverse Stock Splits any time within one year after stockholder approval is obtained, with the exact timing and split ratio of each Reverse Stock Split to be determined at the discretion of our Board (within the aggregate range indicated above) and set forth in a public announcement. Even if our stockholders approve this proposal, our Board may determine in its discretion to abandon and not to effectuate any Reverse Stock Splits. In addition, our Board may determine to effect one or more Reverse Stock Splits even if the trading price of our common stock is at or above $1.00 per share.

**Background**

Our common stock is currently listed on the Nasdaq Capital Market under the symbol "SLNH." The continued listing requirements of the Nasdaq Capital Market provide, among other things, that our common stock must maintain a closing bid price in excess of $1.00 per share. On May 8, 2025, we received a written notice from the Listing Qualifications Department of The Nasdaq Stock Market LLC ("Nasdaq") notifying us that, for thirty (30) consecutive business days preceding the receipt of the notice, the bid price for our common stock had closed below the minimum $1.00 per share requirement set forth in Nasdaq Listing Rule 5450(a)(1) for continued listing on The Nasdaq Capital Market (the "Minimum Bid Price Requirement"). We were provided an initial period of one hundred eighty (180) calendar days, or until November 4, 2025, to regain compliance with the Minimum Bid Price Requirement.

To regain compliance, the closing bid price of our common stock must meet or exceed $1.00 per share for a minimum of ten consecutive trading days during this 180-day period. If we are not in compliance by the end of the 180-day period, we may be eligible for additional time to regain compliance. To qualify, we would be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for the Nasdaq Capital Market, except for the Minimum Bid Price Requirement. In addition, we would be required to notify Nasdaq of our intent to cure the minimum bid price deficiency. If we do not regain compliance within the allotted compliance periods, including any extensions that may be granted by Nasdaq, Nasdaq will provide notice that our common stock will be subject to delisting. We would then be entitled to appeal Nasdaq's determination, but there can be no assurance that Nasdaq would grant our request for continued listing.

Moreover, if the closing bid price of our common stock is $0.10 or less for ten consecutive trading days (the "Low Price Requirement"), Nasdaq will provide notice that our common stock will be subject to delisting as set forth in Listing Rule 5810(c)(3)(A)(iii). We would then be entitled to appeal Nasdaq's determination, but there can be no assurance that Nasdaq would grant our request for continued listing.

Our Board determined that the continued listing of our common stock on the Nasdaq Capital Market is beneficial for our stockholders. The delisting of our common stock from the Nasdaq Capital Market would likely have very serious consequences for us and our stockholders. If our common stock is delisted from the Nasdaq Capital Market, our Board believes that the trading market for our common stock could become significantly less liquid, which could reduce the trading price of our common stock and increase the transaction costs of trading in shares of our common stock.

Approval of this proposal will grant our Board the authority, without further action by our stockholders, to carry out one or more Reverse Stock Splits at any time within one year after stockholder approval is obtained, with the exact timing and split ratio (within the aggregate range indicated above) and timing of each such Reverse Stock Split to be determined at the discretion of our Board.

Even if our stockholders approve this proposal, our Board may determine in its discretion not to effect any Reverse Stock Splits.

**Effective Time**

If this proposal is approved and our Board determines to effect one or more Reverse Stock Splits, the exact timing (within the year after stockholder approval has been obtained) of each Reverse Stock Split will be determined at the discretion of our Board and set forth in a public announcement.

If this proposal is approved, no further action on the part of stockholders would be required to either effect or abandon a Reverse Stock Split. If our Board does not implement one or more Reverse Stock Splits within one year after stockholder approval is obtained, the authority granted in this proposal to implement any Reverse Stock Splits will terminate. Our Board reserves its right to elect not to proceed and abandon the Reverse Stock Split if it determines, in its sole discretion, that this proposal is no longer in the best interests of our stockholders.

**Reasons for a Reverse Stock Split**

The principal purpose of a Reverse Stock Split is to decrease the total number of shares of our common stock outstanding and proportionately increase the market price of our common stock above $1.00 per share in order to meet the continuing listing requirements of the Nasdaq Capital Market. Accordingly, our Board approved the Reverse Stock Split Proposal in order to help ensure that the share price of our common stock meets the continued listing requirements of the Nasdaq Capital Market. Our Board intends to effect the Reverse Stock Split only if it believes that a decrease in the number of shares outstanding is in our and our stockholders' best interests and is likely to improve the trading price of the shares of our common stock and improve the likelihood that we will be allowed to maintain our continued listing on the Nasdaq Capital Market. However, our Board may determine to effect one or more Reverse Stock Splits even if the trading price of our common stock is at or above $1.00 per share (or above the Low Price Requirement, in the event the closing bid price of common stock falls below the Low Price Requirement).

**Board Discretion to Implement the Reverse Stock Split**

Our Board believes that stockholder approval of an aggregate range of Reverse Stock Split ratios (rather than a single split ratio) and one or more Reverse Stock Splits is in the best interests of our stockholders because it provides our Board with the flexibility to achieve the desired results of one or more Reverse Stock Splits and because it is not possible to predict market conditions at the time any Reverse Stock Split would be implemented. If stockholders approve this proposal, our Board would carry out a Reverse Stock Split only upon our Board's determination that a Reverse Stock Split would be in the best interests of the Company and our stockholders at that time. Our Board would then set the ratio for the Reverse Stock Split within the aggregate range approved by stockholders and in an amount it determines is advisable and in the best interests of the stockholders considering relevant market conditions at the time the Reverse Stock Split is to be implemented. In determining the Reverse Stock Split ratio, following receipt of stockholder approval, our board of the directors may consider numerous factors including:

● the historical and projected performance of our common stock;

● general economic and other related conditions prevailing in our industry and in the marketplace;

● the projected impact of the Reverse Stock Split ratio on trading liquidity in our common stock and our ability to maintain continued listing on the Nasdaq Capital Market;

● our capitalization (including the number of shares of our common stock issued and outstanding);

● the then-prevailing trading price for our common stock and the volume level thereof; and

● the potential devaluation of our market capitalization as a result of the Reverse Stock Split.

Our Board intends to select a Reverse Stock Split ratio (within the aggregate range indicated above) that it believes would be most likely to achieve the anticipated benefits of each Reverse Stock Split.

**Certain Risks Associated with One or More Reverse Stock Splits**

Before voting on this proposal, stockholders should consider the following risks associated with effecting any Reverse Stock Split:

● As noted above, the principal purpose of each Reverse Stock Split is to increase the market price of our common stock in order to meet the continuing listing requirements of the Nasdaq Capital Market. However, the Reverse Stock Split(s), if effected, may not increase the market price of our common stock in proportion to the reduction in the number of shares of our common stock outstanding, or at all. If the proposed Reverse Stock Split does result in an increase in the market price of our common stock, the increase may not be long-term or permanent. The market price of our common stock is dependent on many factors, including our business and financial performance, general market conditions, prospects for future growth and other factors detailed from time to time in the reports we file with the SEC. We cannot predict the effect that the Reverse Stock Split may have upon the market price of our common stock with any certainty, and the history of similar reverse stock splits for companies in similar circumstances to ours is varied. The total market capitalization of our common stock after the proposed Reverse Stock Split may be lower than the total market capitalization before the proposed Reverse Stock Split and, in the future, the market price of our common stock following the Reverse Stock Split may not exceed or remain higher than the market price prior to the proposed Reverse Stock Split.

● Even if our stockholders approve the Reverse Stock Split Proposal and one or more Reverse Stock Splits are effected, there can be no assurance that we will continue to meet the continued listing requirements of the Nasdaq Capital Market.

● Any Reverse Stock Split may result in some stockholders owning "odd lots" of less than 100 shares of common stock on a post-split basis. These odd lots may be more difficult to sell, or require greater transaction costs per share to sell, than shares in "round lots" of even multiples of 100 shares. Although our Board believes that the decrease in the number of shares of common stock outstanding as a consequence of a Reverse Stock Split and the anticipated increase in the market price of common stock could encourage interest in our common stock and possibly promote greater liquidity for stockholders, such liquidity could also be adversely affected by the reduced number of shares outstanding after such Reverse Stock Split.

**Principal Effects of a Reverse Stock Split**

If a Reverse Stock Split(s) is approved and effected with respect to our issued and outstanding common stock, each holder of common stock outstanding immediately prior to the effectiveness of a Reverse Stock Split will own a reduced number of shares of common stock upon effectiveness of such Reverse Stock Split. A Reverse Stock Split would be effected simultaneously for all outstanding shares of common stock at the same split ratio. Except for adjustments that may result from the treatment of fractional shares (as described below), a Reverse Stock Split would affect all stockholders uniformly and would not change any stockholder's percentage ownership interest in us. The relative voting rights and other rights and preferences that accompany the shares of common stock will not be affected by a Reverse Stock Split. Shares of common stock issued pursuant to a Reverse Stock Split will remain fully paid and nonassessable.

A Reverse Stock Split will not affect the number of authorized shares of common stock. Although a Reverse Stock Split will not, by itself, have any immediate dilutive effect on stockholders, the proportion of shares owned by stockholders relative to the number of shares authorized for issuance will decrease because the number of authorized shares of common stock would remain unchanged. As a result, additional authorized shares of common stock would become available for issuance at such times and for such purposes as our Board may deem advisable without further action by stockholders, except as required by applicable law or stock exchange rules. To the extent that additional authorized shares of common stock are issued in the future, such shares could be dilutive to our existing stockholders by decreasing such stockholders' percentage of equity ownership in us.

Assuming this proposal is approved by the stockholders and implemented by the Board:

Stock, (iv) 2,347,134 shares of our common stock issuable upon the exercise of outstanding warrants, including pre-funded warrants, at
a weighted average exercise price of $5.42 per share, (v) 1,720,565 shares of our common stock reserved for issuance under our equity
incentive plans.

(3) The
 price per share indicated reflects solely the application of the applicable reverse split ratio to the closing price of the common
 stock on June 30, 2025.

A Reverse Stock Split will have no effect on the number of authorized shares of preferred stock or the par value of the preferred stock.

***Effect on the Equity Incentive Plans, Outstanding Options and Warrants and other convertible securities, including our Series B Preferred Stock***

If the Reverse Stock Split Proposal is approved and effected, the total number of shares of common stock reserved for issuance under our equity incentive plans would be reduced in proportion to the ratio selected by our Board. The total number of shares of common stock reserved for issuance pursuant to outstanding but unexercised warrants would be reduced for each Reverse Stock Split in proportion to the relevant Reverse Stock Split ratio.

Under the terms of our outstanding equity awards, options, warrants, and the terms of the Certificate of Designation for the Series B Preferred Stock, each Reverse Stock Split would adjust and proportionately reduce the number of shares of common stock issuable upon exercise, vesting or conversion of such awards, options, warrants and Series B Preferred Stock in the same ratio of such Reverse Stock Split and, correspondingly, would proportionately increase the exercise price, purchase price or conversion price, if any, of all such awards, options, warrants and Series B Preferred Stock. The number of shares of common stock issuable upon exercise, vesting or conversion of outstanding equity awards, options, warrants and Series B Preferred Stock and the exercise or purchase price related thereto, if any, would be equitably adjusted in accordance with the terms of the equity incentive plans, warrants or Certificate of Designation for the Series B Preferred Stock, which may include rounding the number of shares of common stock issuable down (or in the case of the Series B Preferred Stock, up) to the nearest whole share.

***Potential Anti-Takeover Effect***

An additional effect of a Reverse Stock Split would be to increase the relative amount of authorized but unissued shares of common stock, which may, under certain circumstances, be construed as having an anti-takeover effect. Although not designed or intended for such purposes, the effect of the increased available shares might be to make more difficult or to discourage an attempt to take over or otherwise acquire control of us (for example, by permitting issuances that would dilute the stock ownership of a person or entity seeking to effect a change in the composition of our Board or contemplating a tender offer or other change in control transaction).

Our Board is not presently aware of any attempt, or contemplated attempt, to acquire control of us, and the Reverse Stock Split Proposal is not part of any plan by our Board to recommend or implement any anti-takeover measure.

***Accounting Matters***

A Reverse Stock Split will not affect the par value of our common stock. As a result, at the effective time of a Reverse Stock Split, the stated capital on our balance sheet attributable to the common stock will be reduced in the same proportion as the Reverse Stock Split ratio, and the additional paid-in capital account will be credited with the amount by which the stated capital is reduced. The per share net income or loss will be restated for prior periods to conform to the post-Reverse Stock Split presentation.

**Mechanics of a Reverse Stock Split**

***Effect on Registered "Book-Entry" Holders of our Common stock***

Holders of common stock hold some or all of their common stock electronically in book-entry or "street name" form under the direct registration system for securities. These stockholders will not have stock certificates evidencing their ownership. They are, however, provided with a statement reflecting the number of shares of common stock registered in their accounts. If you hold registered common stock in book-entry form, you do not need to take any action to receive your post-split shares, if applicable.

***Fractional Shares***

We will not issue fractional shares in connection with a Reverse Stock Split, if implemented. Instead, stockholders who otherwise would be entitled to receive fractional shares because they hold a number of shares not evenly divisible by the Reverse Stock Split ratio will automatically be entitled to receive an additional fraction of a share of common stock to round up to the next whole share. In any event, cash will not be paid for fractional shares.

**No Dissenter's or Appraisal Rights**

Our stockholders are not entitled to any dissenter's or appraisal rights with respect to any Reverse Stock Split, and we will not independently provide stockholders with any such right.

**No Going Private Transaction**

Notwithstanding the decrease in the number of outstanding shares of common stock following the implementation of any Reverse Stock Splits, the Board does not intend for this transaction to be the first step in a "going private transaction" within the meaning of Rule 13e-3 of the Exchange Act and the implementation of the proposed Reverse Stock Split(s) will not cause the Company to go private.

**Certain U.S. Federal Income Tax Considerations of the Reverse Stock Split**

The following summary describes, as of the date of this Proxy Statement, certain U.S. federal income tax consequences of any Reverse Stock Split to holders of our common stock. This summary addresses the tax consequences only to a U.S. holder, which is a beneficial owner of our common stock that is either:

● an individual citizen or resident of the United States;

● a corporation, or other entity taxable as a corporation for U.S. federal income tax purposes, created or organized in or under the laws of the United States or any state thereof or the District of Columbia;

● an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or

● a trust, if: (i) a court within the United States is able to exercise primary jurisdiction over its administration and one or more U.S. persons has the authority to control all of its substantial decisions or (ii) it was in existence before August 20, 1996 and a valid election is in place under applicable Treasury regulations to treat such trust as a U.S. person for U.S. federal income tax purposes.

This summary is based on the provisions of the Internal Revenue Code of 1986, as amended (the "**Code**"), U.S. Treasury regulations promulgated thereunder, administrative rulings and judicial authority, all as in effect as of the date of this Proxy Statement. Subsequent developments in U.S. federal income tax law, including changes in law or differing interpretations, which may be applied retroactively, could have a material effect on the U.S. federal income tax consequences of the Reverse Stock Split. We have 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, and there can be no assurance that the Internal Revenue Service will not challenge the statements and conclusions set forth below or that a court would not sustain any such challenge.

This summary does not address all of the tax consequences that may be relevant to any particular investor, including tax considerations that arise from rules of general application to all taxpayers or to certain classes of taxpayers or that are generally assumed to be known by investors. This summary also does not address the tax consequences to (i) persons that may be subject to special treatment under U.S. federal income tax law, such as banks, insurance companies, thrift institutions, regulated investment companies, real estate investment trusts, tax-exempt organizations, certain former U.S. citizens and lawful permanent residents of the United States, persons whose functional currency is not the U.S. dollar, partnerships or other pass-through entities (including S-corporations), traders in securities that elect to mark-to-market and dealers in securities or currencies, (ii) persons that hold our common stock as part of a position in a "straddle" or as part of a "hedging transaction," "conversion transaction" or other integrated investment transaction for federal income tax purposes, (iii) persons that do not hold our common stock as "capital assets" (generally, property held for investment), (iv) persons liable for the alternative minimum tax, (v) persons that directly, indirectly or constructively, own 5% or more of the total combined voting power of our stock or of the total value of our equity interests or (vi) persons that will hold shares of common stock in connection with a permanent establishment or fixed base outside the United States. This summary does not address backup withholding and information reporting. This summary does not address U.S. holders who beneficially own common stock through a "foreign financial institution" (as defined in Code Section 1471(d)(4)) or certain other non-U.S. entities specified in Code Section 1472. This summary does not address U.S. federal tax considerations other than income tax considerations (such as Medicare contribution tax on net investment income, the alternative minimum tax, or estate or gift taxes) or tax considerations arising under any U.S. state or local or non-U.S. laws. In addition, this summary does not address the tax consequences of transactions effectuated before, after or at the same time as the Reverse Stock Split, whether or not they are in connection with a Reverse Stock Split.

If a partnership (or other entity classified as a partnership for U.S. federal income tax purposes) is the beneficial owner of our common stock, the U.S. federal income tax treatment of a partner in the partnership will generally depend on the status of the partner and the activities of the partnership. Partnerships that hold our common stock, and partners in such partnerships, should consult their own tax advisors regarding the U.S. federal income tax consequences of a Reverse Stock Split.

Each holder should consult his, her or its own tax advisors concerning the particular tax consequences of a Reverse Stock Split to them.

***General Tax Treatment of a Reverse Stock Split***

Each Reverse Stock Split is intended to qualify as a "recapitalization" for U.S. federal income tax purposes within the meaning of Section 368(a)(1)(E) of the Code. Assuming the Reverse Stock Split qualifies as a reorganization and other than with respect to a U.S. holder that receives a full share in lieu of a fractional share, as described below, a U.S. holder generally will not recognize gain or loss upon the exchange or deemed exchange of shares of our common stock for a lesser number of shares of our common stock, based upon the Reverse Stock Split ratio. A U.S. holder's aggregate adjusted tax basis in the lesser number of shares of our common stock received in the Reverse Stock Split will be the same as such U.S. holder's aggregate adjusted tax basis in the shares of our common stock that such U.S. holder owned immediately prior to the Reverse Stock Split. The holding period for the shares of our common stock received in the Reverse Stock Split will include the period during which a U.S. holder held the shares of our common stock that were surrendered in the Reverse Stock Split. The United States Treasury regulations provide detailed rules for allocating the tax basis and holding period of the shares of our common stock surrendered to the shares of our common stock received pursuant to the Reverse Stock Split. U.S. holders of shares of our common stock acquired on different dates and at different prices should consult their tax advisors regarding the allocation of the tax basis and holding period of such shares.

Certain information about the effects of the Reverse Stock Split on the basis of holders of our common stock will be included in Internal Revenue Service Form 8937, Report of Organizational Actions Affecting Basis of Securities, which we will post to our website on or before the 45th day following the effective date of the Reverse Stock Split, if effected.

As noted above, we will not issue fractional shares in connection with the Reverse Stock Split. Instead, stockholders who would be entitled to receive fractional shares because they hold a number of shares of common stock not evenly divisible by the Reverse Stock Split ratio will automatically be entitled to receive an additional fraction of a share of common stock to round up to the next whole share of common stock. The U.S. federal income tax consequences of the receipt of such an additional fraction of a share are not clear. A U.S. holder that receives a full share in lieu of a fractional share may recognize income as a deemed distribution or gain in an amount not to exceed the excess of the fair market value of such share over the fair market value of the fractional share to which such stockholder was otherwise entitled. We are not making any representations as to whether the receipt of one whole share in lieu of a fractional share will result in income as a deemed distribution or gain to any stockholder. U.S. holders are urged to consult their own tax advisors as to the possible tax consequences of receiving an additional fraction of a share in the Reverse Stock Split.

THE FOREGOING IS INTENDED ONLY AS A SUMMARY OF CERTAIN FEDERAL INCOME TAX CONSEQUENCES OF THE REVERSE STOCK SPLIT AND DOES NOT CONSTITUTE A TAX OPINION. EACH HOLDER OF OUR COMMON SHARES SHOULD CONSULT ITS OWN TAX ADVISOR REGARDING THE TAX CONSEQUENCES OF A REVERSE STOCK SPLIT TO THEM AND FOR REFERENCE TO APPLICABLE PROVISIONS OF THE CODE.

***Required Vote***

Each Reverse Stock Split will be effectuated pursuant to NRS 78.2055. In accordance with such statute and our bylaws, approval of the Reverse Stock Split Proposal requires the affirmative vote of the holders of a majority of the votes cast in person via attendance at the virtual Annual Meeting or by proxy and voting at the Annual Meeting. As a result, abstentions and broker non-votes, if any, will not affect the outcome of the vote on this proposal.

**PROPOSAL 3: APPROVAL OF THE ADJOURNMENT OF THE ANNUAL MEETING IN THE EVENT THAT THE NUMBER OF SHARES OF COMMON STOCK PRESENT OR REPRESENTED BY PROXY AT THE ANNUAL MEETING AND VOTING "FOR" THE APPROVAL OF THE REVERSE STOCK SPLIT PROPOSAL ARE INSUFFICIENT TO APPROVE SUCH PROPOSAL**

**Adjournment of the Annual Meeting**

In the event that the number of shares of Voting Capital Stock present or represented by proxy at the Annual Meeting and voting "FOR" the approval of the Reverse Stock Split Proposal is insufficient to approve such proposal, we may move to adjourn the Annual Meeting in order to enable us to solicit additional proxies in favor of the approval of the Reverse Stock Split Proposal. In that event, we will ask stockholders to vote only upon the adjournment proposal and not on any other proposal discussed in this Proxy Statement. If the adjournment is for more than sixty (60) days after the date set for the Annual Meeting, the Board will fix a new record date and, a notice of the new meeting shall be given to each stockholder of record entitled to vote at such meeting.

For the avoidance of doubt, any proxy authorizing the adjournment of the Annual Meeting shall also authorize successive adjournments thereof, at any meeting so adjourned, to the extent necessary for us to solicit additional proxies in favor of the approval of any such proposal.

***Required Vote***

The approval of the Adjournment Proposal will require the affirmative vote of the holders of a majority of the votes cast in person via attendance at the virtual Annual Meeting or by proxy and voting at the Annual Meeting.
