Termination and Settlement Agreement

On December 19, 2023, we entered into a Termination and Settlement Agreement (the “Settlement Agreement”) with the Selling Shareholder and certain other parties named therein, under which we agreed, among other things, to register the resale of the 8,075,607 shares of the Company’s common stock that the Selling Shareholder purchased from the Company pursuant to the terms of that certain First Tranche Stock Purchase Agreement, dated April 27, 2023, between us and the Selling Shareholder, as more fully described in the section entitled “Selling Shareholder.”

Investment in any securities offered pursuant to this prospectus involves risks. You should carefully consider and evaluate all of the information included and incorporated by reference or deemed to be incorporated by reference in this prospectus, including the risks described under the heading “Risk Factors” included in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, and any subsequent Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q or Current Reports on Form 8-K we file after the date of this prospectus, and all other information contained or incorporated by reference into this prospectus, as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in any applicable prospectus supplement before acquiring any of such securities. If any of these risks actually occur, it may materially harm our business, financial condition, liquidity and results of operations. As a result, the market price of our securities could decline, and you could lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may become material and adversely affect our business.

Sales of substantial amounts of our common stock by the Selling Shareholder, or the perception that these sales could occur, could adversely affect the price of our common stock.

We are registering the offer and sale of the shares of common stock covered by this prospectus to, among other things, satisfy our obligation in the Settlement Agreement to register the resale of such shares in accordance with the registration rights we granted to the Selling Shareholder under Registration Rights Agreement (as defined below), so that such shares of common stock may be offered for sale into the public market by the Selling Shareholder. The number of shares of common stock covered by this prospectus is significant in relation to our currently outstanding common stock and the historical trading volume of our common stock. The sale by the Selling Shareholder of all or a significant portion of the shares of common stock covered by this prospectus could have a material adverse effect on the market price of our common stock. In addition, the perception in the public markets that the Selling Shareholder might sell all or a portion of the shares of common stock covered by this prospectus could also, in and of itself, have a material adverse effect on the market price of our common stock.

This prospectus, any prospectus supplement and any related free writing prospectus, including the information incorporated by reference herein and therein, contain or may contain “forward-looking statements” within the meaning of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements include statements preceded by, followed by or that include the words “may,” “could,” “would,” “should,” “believe,” “expect,” “anticipate,” “plan,” “estimate,” “target,” “project,” “intend” and similar words or expressions. In addition, any statements that refer to expectations, projections, or other characterizations of future events or circumstances are forward-looking statements.

These forward-looking statements, which reflect our beliefs, objectives, and expectations as of the date hereof, are based on the best judgement of management. All forward-looking statements speak only as of the date on which they are made. Such forward-looking statements are subject to certain risks, uncertainties and assumptions relating to factors that could cause actual results to differ materially from those anticipated in such statements, including, without limitation, the following: economic, social and political conditions, global economic downturns resulting from extraordinary events; securities industry risks; interest rate risks; liquidity risks; credit risk with clients and counterparties; risk of liability for errors in clearing functions; systemic risk; systems failures, delays and capacity constraints; network security risks; competition; reliance on external service providers; new laws and regulations affecting our business; net capital requirements; extensive regulation, regulatory uncertainties and legal matters; failure to maintain relationships with employees, customers, business partners or governmental entities; the inability to achieve synergies or to implement integration plans and other consequences associated with risks and uncertainties discussed under Item 1A, “Risk Factors,” in our most recent Annual Report on Form 10-K and our subsequent Quarterly Reports on Form 10-Q, as updated by our subsequent filings with the SEC.

We caution that the foregoing list of factors is not exclusive, and new factors may emerge, or changes to the foregoing factors may occur, that could impact our business. We undertake no obligation to publicly update or revise these statements, whether as a result of new information, future events or otherwise, except to the extent required by the federal securities laws.

We will not receive any of the proceeds from any sale or other disposition of the common stock covered by this prospectus. All proceeds from the sale or other disposition of such common stock will be paid directly to the Selling Shareholder.

We will bear the out-of-pocket costs, expenses and fees incurred in connection with the registration of shares of our common stock to be sold by the Selling Shareholder pursuant to this prospectus, including, without limitation, all registration and filing fees and fees and expenses of our counsel. The Selling Shareholder will bear all incremental selling expenses relating to the sale of our common stock, such as underwriters’ commissions and discounts, brokerage fees, underwriter marketing costs and all fees and expenses of its counsel and advisors.

The shares of our common stock covered by this prospectus are for the account of the Selling Shareholder, which were issued to the Selling Shareholder in connection with the consummation of the First Tranche on May 18, 2023, as described below.

On April 27, 2023, we entered into: (i) a First Tranche Stock Purchase Agreement with the Selling Shareholder, pursuant to which we agreed to issue and sell to the Selling Shareholder 8,075,607 shares of common stock (the “First Tranche Shares,” and such transaction, the “First Tranche”) at a per share price of $2.15; and (ii) a Second Tranche Stock Purchase Agreement (the “Second Tranche SPA”) with the Selling Shareholder, pursuant to which we agreed to issue and sell to the Selling Shareholder an additional 25,756,470 shares of our common stock (the “Second Tranche Shares,” and such transaction, the “Second Tranche”) at a per share price of $2.35.

The closing of the First Tranche occurred on May 18, 2023. In connection with the First Tranche Stock Purchase Agreement, we entered into a Registration Rights and Lock-Up Agreement, dated as of May 19, 2023 (the “Registration Rights Agreement”) with the Selling Shareholder, whereby we agreed, among other things, to grant the Selling Shareholder certain registration rights with respect to certain securities of the Company held by the Selling Shareholder.

On December 19, 2023, we entered into the Settlement Agreement with the Selling Shareholder and certain other parties named therein, pursuant to which we agreed, among other things, to register the resale of the First Tranche Shares under timeframes specified in the Settlement Agreement and as otherwise provided in the Registration Rights Agreement.

Under the Settlement Agreement, the parties mutually agreed to terminate the Second Tranche SPA pursuant to which the Company had agreed to issue to the Selling Shareholder the Second Tranche Shares. Certain related agreements were also terminated, including the Foreign Broker-Dealer Fee Sharing Agreement, dated April 27, 2023, between Muriel Siebert and Kakaopay Securities, and the Support and Restrictive Covenant Agreements by certain Gebbia shareholders, each dated April 27, 2023. The parties also agreed (i) to amend and restate the Company’s existing Stockholders’ Agreement, dated May 19, 2023 (such agreement, as amended and restated, the “A&R Stockholders’ Agreement”), (ii) that the Company will pay the Selling Shareholder a fee of $5 million (payable in ten quarterly installments beginning on March 29, 2024), (iii) to customary releases and (iv) that the Selling Shareholder will continue to own the First Tranche Shares it purchased from the Company in May 2023, and the Company will register the resale of such shares under timeframes specified in the Settlement Agreement and as otherwise provided in the Registration Rights Agreement. The Selling Shareholder agreed to certain standstill restrictions with respect to its ownership of the Company’s common stock, subject to certain conditions.

Under the A&R Stockholders’ Agreement, the Selling Shareholder retained its right to designate one director to serve on our board of directors. Pursuant to such right, following the closing of the First Tranche, the Selling Shareholder designated Hocheol Shin to serve as a director of the Company, and he was appointed to our board of directors on May 24, 2023.

We are registering the above-referenced shares of our common stock to permit the Selling Shareholder and its pledgees, donees, assignees, transferees or other successors-in-interest that receive its shares after the date of this prospectus to resell or otherwise dispose of the shares in the manner contemplated under “Plan of Distribution” below.

The following table sets forth the name of the Selling Shareholder, the number of shares owned by the Selling Shareholder, the number of shares that may be offered under this prospectus and the number of shares of our common stock owned by the Selling Shareholder assuming all of the shares covered hereby are sold. The number of shares in the column “Number of Shares Being Offered” represents all of the shares that the Selling Shareholder may offer under this prospectus. The Selling Shareholder may sell some, all or none of its shares. We do not know how long the Selling Shareholder will hold the shares before selling them, and, except as described in this prospectus, we currently have no agreements, arrangements or understandings with the Selling Shareholder regarding the sale or other disposition of any of the shares. The shares covered hereby may be offered from time to time by the Selling Shareholder.

The information set forth below is based upon information obtained from the Selling Shareholder and upon information in our possession regarding the issuance of shares of common stock to the Selling Shareholder in connection with the First Tranche.

The following description of our common stock and certain provisions of our certificate of incorporation, as amended, and our by-laws are summaries and are qualified by reference to the certificate of incorporation, as amended, and the by-laws. Copies of these documents have been filed with the SEC as exhibits to our registration statement, of which this prospectus forms a part.

Our authorized capital stock consists of 100,000,000 shares of common stock, par value $.01 per share.

Holders of common stock have no cumulative voting rights, redemption rights or preemptive rights to purchase or subscribe for any shares of our common stock or other securities. All of the outstanding shares of common stock are fully paid and nonassessable.

Antitakeover Effects of Provisions of Our Certificate of Incorporation and By-laws and of New York Law

Section 912 of the NYBCL. As a New York corporation that has a class of voting stock listed on a national securities exchange, we are subject to the provisions of Section 912 of the New York Business Corporation Law (“NYBCL”). In general, Section 912 prohibits a public New York corporation from engaging in a “business combination” with an “interested shareholder” for a period of five years from the date on which the shareholder first becomes an interested shareholder unless such business combination or the purchase of stock made by such interested shareholder on such interested shareholder’s stock acquisition date is approved by the board of directors prior to such interested shareholder’s stock acquisition date. In addition, no domestic corporation shall engage at any time in any business combination with any interested shareholder of such corporation other than in situation where: (i) the business combination is approved by the board of directors before the stock acquisition or the acquisition of the stock had been approved by the board of directors before the stock acquisition; (ii) the business combination is approved by the affirmative vote of the holders of at least a majority of the outstanding shares of stock entitled to vote not beneficially owned by the interested shareholder at a meeting called for that purpose no earlier than five years after the stock acquisition; or (iii) in the business combination, the interested shareholder pays a formula price designed to ensure that all other shareholders receive at least the highest price per share that is paid by the interested shareholder and such business combination meets certain other requirements. The NYBCL defines the term “business combination” to include transactions such as certain mergers, consolidations, dispositions of assets or stock, issuance or transfer of any stock, plans for liquidation or dissolution, reclassifications of securities, recapitalizations and similar transactions. The NYBCL defines the term “interested shareholder” generally as any person who owns at least twenty-percent (20%) of the outstanding shares of stock entitled to vote or is an affiliate or associate of such corporation and at any time within the five-year period immediately prior to the date in question owned at least twenty-percent (20%) of the then outstanding shares of stock entitled to vote. A corporation can expressly elect not to be governed by the NYBCL’s business combination provision in its bylaws, which must be approved by the affirmative vote of the holders of at least a majority of the outstanding shares of stock entitled to vote and is subject to further conditions, but we have not done so.

Board of Directors. Our board of directors currently consists of seven directors, but the number of directors may be increased or decreased, to not less than three or more than nine, by resolution of a majority of the entire board of directors or by the shareholders at an annual or any special meeting; provided, however, that if our shares are owned beneficially and of record by less than three shareholders, the number of directors may, if so determined by resolution of the board of directors or by our shareholders at an annual or special meeting, be less than three but not less than the number of shareholders. The Selling Shareholder is entitled to designate one director to serve on our board of directors.

Special Meetings of Shareholders. Special meetings of our shareholders may be called only by our President or by resolution of our board of directors.

On December 19, 2023, we entered into the Settlement Agreement with the Selling Shareholder and certain other parties named therein, pursuant to which we agreed, among other things, to submit to or file with the SEC a registration statement, of which this prospectus forms a part, for the resale of the First Tranche Shares under timeframes specified in the Settlement Agreement.

The transfer agent and registrar for our common stock is American Stock Transfer & Trust Company, LLC, with offices at 6201 15th Avenue, Brooklyn, New York 11219.

Our common stock is listing for trading on the Nasdaq Capital Market under the symbol “SIEB.”

The Selling Shareholder and any of its pledgees, donees, transferees, assignees or other successors-in-interest may, from time to time, sell, transfer or otherwise dispose of any or all of their shares of common stock or interests in shares of common stock on any stock exchange, market or trading facility on which the shares are traded or in private transactions. These dispositions may be at fixed prices, at prevailing market prices at the time of sale, at prices related to the prevailing market price, at varying prices determined at the time of sale, or at negotiated prices. The Selling Shareholder may use one or more of the following methods when disposing of the shares or interests therein:

The Selling Shareholder may also sell shares under Rule 144 or any other exemption from registration under the Securities Act of 1933, as amended (the “Securities Act”), if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Shareholder may arrange for other broker-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Shareholder (or, if any broker-dealer acts as agent for the purchaser of shares, from the purchaser) in amounts to be negotiated. The Selling Shareholder does not expect these commissions and discounts to exceed what is customary in the types of transactions involved.

The Selling Shareholder may from time to time pledge or grant a security interest in some or all of the shares of common stock owned by it and, if it defaults in the performance of its secured obligations, the pledgees or secured parties may offer and sell shares of common stock from time to time under this prospectus, or under a supplement or amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending the list of selling shareholders to include the pledgee, transferee or other successors in interest as selling shareholders under this prospectus. The Selling Shareholder also may transfer and donate the shares of common stock in other circumstances in which case the transferees, donees, pledgees or other successors in interest will be the selling beneficial owners for purposes of this prospectus.

Upon being notified in writing by the Selling Shareholder that any material arrangement has been entered into with a broker-dealer for the sale of common stock through a block trade, special offering, exchange distribution or secondary distribution or a purchase by a broker or dealer, we will file a supplement to this prospectus, if required, pursuant to Rule 424(b) under the Securities Act, disclosing (i) the name of such selling shareholders and of the participating broker-dealer(s), (ii) the number of shares involved, (iii) the price at which such shares of common stock were sold, (iv) the commissions paid or discounts or concessions allowed to such broker-dealer(s), where applicable, (v) that such broker-dealer(s) did not conduct any investigation to verify the information set out or incorporated by reference in this prospectus, and (vi) other facts material to the transaction.

In connection with the sale of the shares of common stock or interests in shares of common stock, the Selling Shareholder may enter into hedging transactions after the effective date of the registration statement of which this prospectus is a part with broker-dealers or other financial institutions, which may in turn engage in short sales of the common stock in the course of hedging the positions they assume. The Selling Shareholder may also sell shares of common stock short after the effective date of the registration statement of which this prospectus is a part and deliver these securities to close out its short positions, or loan or pledge the common stock to broker-dealers that in turn may sell these securities. The Selling Shareholder may also enter into option or other transactions after the effective date of the registration statement of which this prospectus is a part with broker-dealers or other financial institutions or the creation of one or more derivative securities which require the delivery to such broker-dealer or other financial institution of shares offered by this prospectus, which shares such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Shareholder and any broker-dealers or agents that are involved in selling the shares may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the shares purchased by them may be deemed to be underwriting commissions or discounts under the Securities Act.

We have advised the Selling Shareholder that it is required to comply with Regulation M promulgated under the Exchange Act during such time as they may be engaged in a distribution of the shares. The foregoing may affect the marketability of the common stock.

The aggregate proceeds to the Selling Shareholder from the sale of the common stock offered hereby will be the purchase price of the common stock less discounts or commissions, if any. The Selling Shareholder reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of common stock to be made directly or through agents. We will not receive any of the proceeds from this offering.

We are required to pay all fees and expenses in connection with to the registration of the shares. Pursuant to the Registration Rights Agreement, we agreed to indemnify the Selling Shareholder against certain losses, claims, damages and liabilities, including those resulting from violations by the Company of the Securities Act, subject to certain exceptions.

The validity of the shares of common stock being offered by this prospectus will be passed upon for us by Mitchell Silberberg & Knupp LLP.

The following is an estimate of the expenses (all of which are to be paid by the registrant) that we may incur in connection with the securities being registered hereby, other than the Securities and Exchange Commission registration fee.

The following summary is qualified in its entirety by reference to the complete text of the New York Business Corporation Law (“NYBCL”) referred to below and to the certificate of incorporation, as amended, and the by-laws of the Company.

The NYBCL permits a corporation to indemnify any person made, or threatened to be made, a party to an action or proceeding (other than one by or in the right of the corporation to procure a judgment in its favor), whether civil or criminal, by reason of the fact that the person was a director or officer of the corporation (or served another entity in any capacity at the request of the corporation), against judgments, fines, amounts paid in settlement and reasonable expenses, including attorneys’ fees actually and necessarily incurred as a result of such action or proceeding, or any appeal therein, if such director or officer acted, in good faith, for a purpose which the person reasonably believed to be in (or, in the case of service for any other entity), not opposed to, the best interests of the corporation and, in criminal actions or proceedings, in addition, had no reasonable cause to believe that his conduct was unlawful.

The NYBCL provides that the termination of any such civil or criminal action or proceeding by judgment, settlement, conviction or upon a plea of nolo contendere, or its equivalent, shall not in itself create a presumption that any such director or officer did not act, in good faith, for a purpose which he reasonably believed to be in, or, in the case of service for any other corporation or any partnership, joint venture, trust, employee benefit plan or other enterprise, not opposed to, the best interests of the corporation or that he had reasonable cause to believe that his conduct was unlawful.

The NYBCL permits a corporation to indemnify any person made, or threatened to be made, a party to an action by or in the right of the corporation to procure a judgment in its favor by reason of the fact that he is or was a director or officer of the corporation (or is or was serving at the request of the corporation as a director or officer of any other entity) against amounts paid in settlement and reasonable expenses, including attorneys’ fees, actually and necessarily incurred by him in connection with the defense or settlement of such action, or in connection with an appeal therein, if such director or officer acted, in good faith, for a purpose which he reasonably believed to be in, or, in the case of service for any entity, not opposed to, the best interests of the corporation, except that no such indemnification shall be made in respect of (1) a threatened action, or a pending action which is settled or otherwise disposed of, or (2) any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation, unless and only to the extent that the court in which the action was brought, or, if no action was brought, any court of competent jurisdiction, determines upon application that, in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for such portion of the settlement amount and expenses as the court deems proper.

Our certificate of incorporation and by-laws provide that, to the fullest extent permitted by the NYBCL, we will indemnify our present and future directors and officers against all expenses actually and reasonably incurred by them as a result of their being threatened with or otherwise involved in any action, suit or proceeding (other than an action commenced on our own behalf) by virtue of the fact that they are or were one of our officers or directors.

We may also purchase and maintain insurance to indemnify the Company for any obligation we incur as a result of the indemnification of directors and officers, or to indemnify directors and officers, pursuant to our by-laws and in accordance with the NYBCL.

We have obtained officer and director liability insurance with respect to liabilities arising out of various matters, including matters arising under the Securities Act.

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (a)(1)(i), (a)(1)(ii), and (a)(1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to section 13 or section 15(d) of the Exchange Act that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is a part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act to any purchaser:

(i) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities:

The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communications that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

Pursuant to the requirements of the Securities Act of 1933, as amended, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in Miami Beach, Florida, on the 18 day of January, 2024.
