Private Placement of Series AA Preferred Stock and Series AAA Preferred Stock

On November 23, 2025 (the “SPA Effective Date”), we entered into a Securities Purchase Agreement (the “November 2025 Purchase Agreement”) with David Lazar, pursuant to which we agreed to issue and sell, in a private placement, shares of our Series AA Preferred Convertible Preferred Stock, par value $0.001 per share (the “Series AA Preferred Stock”) and our Series AAA Preferred Stock in two closings for aggregate gross proceeds of up to $6.0 million, subject to the terms and conditions set forth in the Securities Purchase Agreement (collectively, the “Private Placement”).

The first closing of the Private Placement occurred on November 24, 2025, pursuant to which we issued and sold to David Lazar an aggregate of 900,000 shares of Series AA Preferred Stock at a price per share equal to $2.00, for aggregate gross proceeds of $1.8 million. Each share of Series AA Preferred Stock is convertible into 55 shares of Common Stock for an aggregate total of 49,500,000 shares of Common Stock issuable upon conversion of the Series AA Preferred Stock.

On December 11, 2025, David Lazar transferred his rights and obligations under the November 2025 Purchase Agreement solely with respect to the shares of Series AAA Preferred and the director nomination rights, to AK Holdings Group Inc., a Panamanian company (“AK Holdings”). On January 29, 2026, pursuant to the terms of that certain Rights Purchase Agreement by and among AK Holdings and each signatory thereto (the “Series AAA Investors”), AK Holdings sold its rights to purchase the Series AAA Preferred Stock (but not its director nomination rights under the November 2025 Purchase Agreement) to the Series AAA Investors.

On January 30, 2026, pursuant to the terms of a Securities Purchase Agreement (the “January 2026 Purchase Agreement” and together with the November 2025 Purchase Agreement, the “Purchase Agreements”), we issued and sold to the Series AAA Investors in a second closing of the Private Placement (the “Second Closing”), an aggregate of 2,100,000 shares of Series AAA Preferred Stock at a price per share of Series AAA Preferred Stock equal to $2.00, for aggregate gross proceeds of $4.2 million. The Second Closing occurred on January 30, 2026. The terms of the Series AAA Preferred Stock are substantially similar to the terms of the Series AA Preferred Stock. Each share of Series AAA Preferred Stock was convertible into 420 shares of common stock for an aggregate total of 882,000,000 shares of Common Stock issuable upon conversion of the Series AAA Preferred Stock. As of the date of this prospectus, all of the shares of Series AAA Preferred Stock have been converted into common stock.

Pursuant to the terms of the November 2025 Purchase Agreement, following (i) the approval at the 2025 Annual Meeting of Stockholders (the “Annual Meeting”) held on January 30, 2026, of the Issuance Proposal and the Share Increase Proposal and (ii) the Second Closing, five (5) nominees of AK Holdings were appointed as directors by the Board of Directors upon the recommendation of the Nominating and Corporate Governance Committee: (A) Avi Minkowitz as a Class II director to serve until the 2028 annual meeting of stockholders or until the election and qualification of his successor or his earlier death, resignation or removal, (B) Hillel Posen and Chaim (Dovi) Berger as Class I directors to serve until the 2027 annual meeting of stockholders or until the election and qualification of their successors or their earlier death, resignation or removal, and (C) Yonatan Colman and Brendan Purdy as Class III directors to serve until the 2026 meeting of stockholders or until the election and qualification of their successors or their earlier death, resignation or removal.

LifeSci and Baker Settlement Agreements

On December 30, 2025, we entered into the Baker Settlement Agreement with Baker Bros. Advisors LP, pursuant to which we agreed to issue the Baker Shares to resolve certain claims relating to participation rights under prior financing arrangements (the “Baker Settlement”). In connection with the Baker Settlement, we and Baker Bros. Advisors LP also entered into a voting agreement pursuant to which Baker Bros. Advisors LP granted an irrevocable proxy in favor of us to vote the settlement shares and other specified shares in line with our Board of Directors’ recommendations for a period of six months.

On December 30, 2025, we also entered into the LifeSci Settlement Agreement pursuant to which we agreed to issue the LifeSci Shares to settle certain payment obligations for financial advisory services.

Resignation and Appointment of Chief Executive Officer and Chief Financial Officer

On February 2, 2026, David Lazar tendered his resignation as Chief Executive Officer and Chief Financial Officer of the Company, effective as of the same date. On February 2, 2026, to fill the executive vacancy from David Lazar’s resignation, the Board of Directors appointed Avi Minkowitz as the Company’s Chief Executive Officer and Chief Financial Officer, effective as of the same date. As of the date of this prospectus, David Lazar remains a director of the Board of Directors.

Nasdaq Market Value of Listed Securities Deficiency

On November 10, 2025, we received a deficiency letter (the “MVLS Letter”) from the Listing Qualifications Department (the “Staff”) of the Nasdaq Stock Market notifying us that the listing of our common stock was not in compliance with Nasdaq Listing Rule 5550(b)(2) (the “Minimum MVLS Requirement”) for continued listing on Nasdaq, as the market value of our listed securities was less than $35 million for the previous 30 consecutive business days.

In accordance with Nasdaq Listing Rule 5810(c)(3)(C), we have been provided a period of 180 calendar days, or until May 11, 2026 (the “MVLS Compliance Date”), to regain compliance with the Minimum MVLS Requirement. If, at any time before the MVLS Compliance Date, the market value of our listed securities closes at $35 million or more for a minimum of 10 consecutive business days, the Staff will provide written notification to us that we have regained compliance with the Minimum MVLS Requirement.

If we do not regain compliance with the Minimum MVLS Requirement by the MVLS Compliance Date, we will receive written notification that our securities are subject to delisting. At that time, we may appeal the Staff’s delisting determination to a Nasdaq Listing Qualifications Panel (the “Panel”) pursuant to the procedures set forth in the applicable Nasdaq Listing Rules. However, there can be no assurance that, if we receive a delisting notice and appeal the delisting determination by the Staff to the Panel, such appeal would be successful.

Nasdaq Minimum Bid Price Requirement Deficiency

On January 20, 2026, we received a letter from the Staff indicating that, based upon the closing bid price of the Company’s common stock for the 30 consecutive business days between December 3, 2025, to January 16, 2026, the Company did not meet the minimum bid price of $1.00 per share required for continued listing on Nasdaq pursuant to Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Rule”). The letter also indicated that we will be provided with a compliance period of 180 calendar days, or until July 20, 2026 (the “Minimum Bid Price Compliance Period”), in which to regain compliance pursuant to Nasdaq Listing Rule 5810(c)(3)(A).

In order to regain compliance with the Minimum Bid Price Rule, our common stock must maintain a minimum closing bid price of $1.00 for at least ten consecutive business days during the Minimum Bid Price Compliance Period. In the event we do not regain compliance by the end of the Minimum Bid Price Compliance Period, we may be eligible for additional time to regain compliance. To qualify, we will be required to meet the continued listing requirement for the market value of its publicly held shares and all other initial listing standards for Nasdaq, with the exception of the bid price requirement, and will need to provide written notice of our intention to cure the deficiency during the second compliance period, by effecting a reverse stock split if necessary. If we meet these requirements, we may be granted an additional 180 calendar days to regain compliance. However, if it appears to Nasdaq that we will be unable to cure the deficiency, or if we are not otherwise eligible for the additional cure period, Nasdaq will provide notice that our common stock will be subject to delisting. There can be no assurance that we will be eligible for the additional 180 calendar day compliance period, if applicable, or that the Nasdaq staff would grant our request for continued listing subsequent to any delisting notification. In the event of such a notification, we may appeal the Staff’s determination to delist its securities.

Risk Factors		Investing in our common stock involves significant risks. See “Risk Factors” beginning on page 5 of this prospectus and under similar headings in the information and documents incorporated by reference in this prospectus.

RISK FACTORS

Investing in our securities involves a high degree of risk. In addition to the other information contained in this prospectus and in the documents we incorporate by reference, you should carefully consider the risks discussed below and under the heading “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, our Quarterly Reports for the quarters ended March 31, 2025, and June 30, 2025, and September 30, 2025, as well as any amendment or update to our risk factors reflected in subsequent filings with the SEC, before making a decision about investing in our securities. The risks and uncertainties discussed below and in the documents incorporated by reference are not the only ones facing us. Additional risks and uncertainties not presently known to us, or that we currently see as immaterial, may also harm our business. If any of these risks occur, our business, financial condition and operating results could be harmed, the trading price of our common stock could decline and you could lose part or all of your investment.

Risks Related to this Offering and Our Common Stock

If we fail to comply with the continued listing requirements of Nasdaq, our common stock may be delisted and the price of our common stock and our ability to access the capital markets could be negatively impacted.

Our common stock is currently listed for trading on Nasdaq. We must satisfy Nasdaq’s continued listing requirements. A delisting of our common stock from Nasdaq could materially reduce the liquidity of our common stock and result in a corresponding material reduction in the price of our common stock. In addition, delisting could harm our ability to raise capital through alternative financing sources on terms acceptable to us, or at all, and may result in the potential loss of confidence by investors, suppliers, customers and employees and fewer business development opportunities.

We have in the past, and may in the future, be unable to comply with certain of the listing standards that we are required to meet to maintain the listing of our common shares on Nasdaq. For example, on November 10, 2025, we received the MVLS Letter from the Staff of the Nasdaq Stock Market notifying us that the listing of our common stock was not in compliance with the Minimum MVLS Requirement for continued listing on Nasdaq, as the market value of our listed securities was less than $35 million for the previous 30 consecutive business days.

In accordance with Nasdaq Listing Rule 5810(c)(3)(C), we have been provided a period of 180 calendar days, or until May 11, 2026, to regain compliance with the Minimum MVLS Requirement. If, at any time before the MVLS Compliance Date, the market value of our listed securities closes at $35 million or more for a minimum of 10 consecutive business days, the Staff will provide written notification to us that we have regained compliance with the Minimum MVLS Requirement. If we do not regain compliance with the Minimum MVLS Requirement by the MVLS Compliance Date, we will receive written notification that its securities are subject to delisting. At that time, we may appeal the Staff’s delisting determination to the Panel pursuant to the procedures set forth in the applicable Nasdaq Listing Rules. However, there can be no assurance that, if we receive a delisting notice and appeal the delisting determination by the Staff to the Panel, such appeal would be successful.

Additionally, On January 20, 2026, we received a letter from the Staff indicating that, based upon the closing bid price of our common stock for the 30 consecutive business days between December 3, 2025, to January 16, 2026, we did not meet the minimum bid price of $1.00 per share required for continued listing on Nasdaq pursuant to the Minimum Bid Price Rule. The letter also indicated that we will be provided with a compliance period of 180 calendar days, or until July 20, 2026, in which to regain compliance pursuant to Nasdaq Listing Rule 5810(c)(3)(A).

There is no assurance that we will regain compliance with the Minimum Bid Price Requirement, the Minimum MVLS requirement, or maintain compliance with the minimum listing requirements with all applicable requirements for continued listing on Nasdaq. If our common stock were delisted from Nasdaq, trading of our common stock would most likely take place on an over-the-counter market established for unlisted securities, such as the OTCQB or the Pink Market maintained by OTC Markets Group Inc. An investor would likely find it less convenient to sell, or to obtain accurate quotations in seeking to buy, our common stock on an over-the-counter market, and many investors would likely not buy or sell our common stock due to difficulty in accessing over-the-counter markets, policies preventing them from trading in securities not listed on a national exchange or other reasons. In addition, as a delisted security, our common stock would be subject to SEC rules as a “penny stock,” which impose additional disclosure requirements on broker-dealers. The regulations relating to penny stocks, coupled with the typically higher cost per trade to the investor of penny stocks due to factors such as broker commissions generally representing a higher percentage of the price of a penny stock than of a higher-priced stock, would further limit the ability of investors to trade in our common stock. In addition, delisting could harm our ability to raise capital through alternative financing sources on terms acceptable to us, or at all, and may result in the potential loss of confidence by investors, suppliers, customers and employees and fewer business development opportunities. For these reasons and others, delisting would adversely affect the liquidity, trading volume and price of our common stock, causing the value of an investment in us to decrease and having an adverse effect on our business, financial condition and results of operations, including our ability to attract and retain qualified employees and to raise capital.

The sale of a substantial amount of our shares in the public market could adversely affect the prevailing market price of our securities.

We are registering for resale up to 241,435,910 shares of our common stock held by the selling stockholders, which is a significant number of shares compared to the current number of total shares of common stock issued and outstanding. Sales of substantial amounts of shares of our common stock in the public market, or the perception that such sales might occur, could adversely affect the market price of our common stock. We cannot predict if and when selling stockholders may sell such shares of our common stock in the public markets. Furthermore, in the future, we may issue additional shares of our common stock or other equity or debt securities convertible into shares of our common stock. Any such issuance could result in substantial dilution to our existing stockholders and could cause the market price of our securities to decline.

PLAN OF DISTRIBUTION

We are registering the shares of common stock issued on conversion and issuable upon conversion of the remaining Preferred Stock to permit the resale of such shares of common stock Preferred Stock from time to time after the date of this prospectus. We will not receive any of the proceeds from the sale by the selling stockholders of the shares of common stock. We will bear all fees and expenses incident to our obligation to register the shares of common stock.

Each selling stockholder of the securities and any of their pledgees, assignees and successors-in-interest may sell all or a portion of the shares of common stock held by them and offered hereby from time to time directly or through one or more underwriters, broker-dealers or agents. If the shares of common stock are sold through underwriters or broker-dealers, the selling stockholders will be responsible for underwriting discounts or commissions or agent’s commissions. The shares of common stock may be sold in one or more transactions at prevailing market prices, at prices related to prevailing market prices or at privately negotiated prices. These sales may be effected in transactions, which may involve crosses or block transactions, pursuant to one or more of the following methods:

●

on any national securities exchange or quotation service on which the securities may be listed or quoted at the time of sale;

●

in the over-the-counter market;

●

in transactions otherwise than on these exchanges or systems or in the over-the-counter market;

●

through the writing or settlement of options, whether such options are listed on an options exchange or otherwise;

●

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

●

block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

●

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

●

an exchange distribution in accordance with the rules of the applicable exchange;

●

privately negotiated transactions;

●

short sales made after the date this registration statement is declared effective by the SEC;

●

broker-dealers may agree with a selling security holder to sell a specified number of such shares at a stipulated price per share;

●

a combination of any such methods of sale; and

●

any other method permitted pursuant to applicable law.

The selling stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act, if available, rather than under this prospectus.

In addition, the selling stockholders may transfer the securities by other means not described in this prospectus. If the selling stockholders effect such transactions by selling securities to or through underwriters, broker-dealers or agents, such underwriters, broker-dealers or agents may receive commissions in the form of discounts, concessions or commissions from the selling stockholders or commissions from purchasers of the securities for whom they may act as agent or to whom they may sell as principal (which discounts, concessions or commissions as to particular underwriters, broker-dealers or agents may be in excess of those customary in the types of transactions involved). In connection with sales of the securities or otherwise, the selling stockholders may enter into hedging transactions with broker-dealers, which may in turn engage in short sales of the securities in the course of hedging in positions they assume. The selling stockholders may also sell securities short and deliver securities covered by this prospectus to close out short positions and to return borrowed shares in connection with such short sales. The selling stockholders may also loan or pledge securities to broker-dealers that in turn may sell such securities.

The selling stockholders may pledge or grant a security interest in some or all of the securities owned by them and, if they default in the performance of their secured obligations, the pledgees or secured parties may offer and sell the securities from time to time pursuant to this prospectus or any amendment to this prospectus under Rule 424(b)(3) or other applicable provision of the Securities Act amending, if necessary, the list of selling stockholders to include the pledgee, transferee or other successors in interest as selling stockholders under this prospectus. The selling stockholders also may transfer and donate the securities 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.

To the extent required by the Securities Act and the rules and regulations thereunder, the selling stockholders and any broker-dealer participating in the distribution of the securities may be deemed to be “underwriters” within the meaning of the Securities Act, and any commission paid, or any discounts or concessions allowed to, any such broker-dealer may be deemed to be underwriting commissions or discounts under the Securities Act. At the time a particular offering of securities is made, a prospectus supplement, if required, will be distributed, which will set forth the aggregate amount of securities being offered and the terms of the offering, including the name or names of any broker-dealers or agents, any discounts, commissions and other terms constituting compensation from the selling stockholders and any discounts, commissions or concessions allowed or re-allowed or paid to broker-dealers.

Under the securities laws of some states, the securities may be sold in such states only through registered or licensed brokers or dealers. In addition, in some states the securities may not be sold unless such shares have been registered or qualified for sale in such state or an exemption from registration or qualification is available and is complied with.

There can be no assurance that any selling stockholder will sell any or all of the securities registered pursuant to the registration statement of which this prospectus forms a part.

The selling stockholders and any other person participating in such distribution will be subject to applicable provisions of the Exchange Act, and the rules and regulations thereunder, including, without limitation, to the extent applicable, Regulation M of the Exchange Act, which may limit the timing of purchases and sales of any of the shares of securities by the selling stockholders and any other participating person. To the extent applicable, Regulation M may also restrict the ability of any person engaged in the distribution of the securities to engage in market-making activities with respect to such securities. All of the foregoing may affect the marketability of the securities and the ability of any person or entity to engage in market-making activities with respect to the securities.

We will pay all expenses of the registration of the securities, including, without limitation, SEC filing fees and expenses of compliance with state securities or “blue sky” laws; provided, however, a selling stockholder will pay all underwriting discounts and selling commissions, if any. We will indemnify the selling stockholders against liabilities, including some liabilities under the Securities Act in accordance with the registration rights agreements or the selling stockholders will be entitled to contribution. We may be indemnified by the selling stockholders against civil liabilities, including liabilities under the Securities Act that may arise from any written information furnished to us by the selling stockholder specifically for use in this prospectus, in accordance with the related registration rights agreements or we may be entitled to contribution.

Once sold under the registration statement, of which this prospectus forms a part, the securities will be freely tradable in the hands of persons other than our affiliates.
