Equity [Abstract] |
STOCKHOLDERS’ EQUITY | NOTE 6 - STOCKHOLDERS’ EQUITY Common Stock The common stock confers upon the holders the right to receive notice to participate and vote in general meetings of the Company, and the right to receive dividends, if declared, and to participate in the distribution of the surplus assets and funds of the Company in the event of liquidation, dissolution or winding up of the Company. On August 17, 2021, the Company’s stockholders voted to approve an amendment to the Company’s Amended and Restated Certificate of Incorporation to increase the number of shares of the Company’s Common Stock authorized for issuance from 24,109,635 shares to 40,000,000 shares. As a result of the vote to increase the number of shares authorized for issuance, the warrants that were previously accounted for as derivative liabilities were marked to market through the date of approval and then reclassified to additional paid in capital (equity), as the Company had sufficient authorized shares to settle the exercise of the warrants. Issuance of common stock for cash On November 29, 2022, the Company entered into a Securities Purchase Agreement with certain institutional investors pursuant to which the Company agreed to sell in a registered direct offering (the “Offering”), 240,000 shares of the Company’s common stock at an offering price of $10.00 per share. The Company received net proceeds from the sale of such offering, after deducting placement agent fees and expenses and offering expenses payable by the Company, of approximately $2.1 million. The Company intends to use the net proceeds for general working capital purposes. On October 6, 2022, the Company entered into an engagement letter with H.C. Wainwright & Co., LLC (the “Wainwright”), pursuant to which Wainwright agreed to serve as the exclusive placement agent for the Company, on a reasonable best-efforts basis, in connection with the Offering. The Company will pay Wainwright an aggregate cash fee equal to 7.5% of the gross proceeds of the Offering, a management fee equal to 1.0% of the gross proceeds of the Offering, a non-accountable expense allowance of $50,000 and $15,950 for clearing fees. Additionally, the Company has agreed to issue to Wainwright or its designees as compensation, warrants to purchase up to 18,000 shares of common stock. The warrants expire on November 29, 2027 and have an exercise price of $12.50 per share. Series C, D and E Preferred Stock conversion to common stock Each share of Series E Preferred Stock is convertible at any time and from time to time at the option of a holder of Series E Preferred Stock into one twentieth of a share of the Company’s common stock, provided that each holder would be prohibited from converting Series E Preferred Stock into shares of the Company’s common stock if, as a result of such conversion, any such holder, together with its affiliates, would own more than 9.99% of the total number of shares of the Company’s common stock then issued and outstanding. This limitation may be waived with respect to a holder upon such holder’s provision of not less than 61 days’ prior written notice to the Company. During the years ended December 31, 2022 and 2021, shareholders converted 0 and 875,000 shares of Series E Preferred Stock into 0 and 43,750 shares of common stock, respectively, at a conversion rate of 20 to 1. No purchase was made to convert these shares. Each share of Series D Preferred Stock is convertible into fifty shares of common stock at any time at the option of the holders, provided that each holder would be prohibited from converting Series D Preferred Stock into shares of common stock if, as a result of such conversion, any such holder, together with its affiliates, would own more than 4.99% of the total number of shares of common stock then issued and outstanding. This limitation may be waived with respect to a holder upon such holder’s provision of not less than 61 days’ prior written notice to the Company. During the years ended December 31, 2022 and 2021, shareholders converted 0 and 153 shares of Series D Preferred Stock into 0 and 7,650 shares of common stock, respectively, at a conversion rate of 1 to 50. No purchase was made in order to convert these shares. Each share of Series C Preferred Stock is convertible into one twentieth of a share of common stock at any time at the option of the holders, provided that each holder would be prohibited from converting Series C Preferred Stock into shares of common stock if, as a result of such conversion, any such holder, together with its affiliates, would own more than 9.99% of the total number of shares of common stock then issued and outstanding. This limitation may be waived with respect to a holder upon such holder’s provision of not less than 61 days’ prior written notice to the Company. During the years ended December 31, 2022 and 2021, shareholders converted 0 and 666,667 shares of Series C Preferred Stock into 0 and 33,333 shares of common stock, respectively, at a conversion rate of 20 to 1. No purchase was made in order to convert these shares. Series F Preferred Stock On September 13, 2022, the Board declared a dividend of one one-thousandth of a share of Series F Preferred Stock, par value $0.001 per share (“Series F Preferred Stock”), for each one share of the Company’s common stock, par value $0.001 per share, to stockholders of record at 5:00 p.m. Eastern Time on October 14, 2022. Each share of Series F Preferred Stock entitles the holder thereof to 1,000,000 votes per share (and, for the avoidance of doubt, each fraction of a share of Series F Preferred Stock has a ratable number of votes). Thus, each one-thousandth of a share of Series F Preferred Stock entitles the holder thereof to 1,000 votes. The outstanding shares of Series F Preferred Stock will vote together with the outstanding shares of common stock of the Company as a single class exclusively with respect to (1) any proposal to adopt an amendment to Certificate of Incorporation to reclassify the outstanding shares of common stock at a ratio specified in or determined in accordance with the terms of such amendment (the “Reverse Stock Split”) and (2) any proposal to adjourn any meeting of stockholders called for the purpose of voting on the Reverse Stock Split (the “Adjournment Proposal”). The Series F Preferred Stock is not entitled to vote on any other matter, except to the extent required under the Delaware General Corporation Law. Unless otherwise provided on any applicable proxy or ballot with respect to the voting on the Reverse Stock Split or the Adjournment Proposal, the vote of each share of Series F Preferred Stock (or fraction thereof) entitled to vote on the Reverse Stock Split, the Adjournment Proposal or any other matter brought before any meeting of stockholders held to vote on the Reverse Stock Split and the Adjournment Proposal will be cast in the same manner as the vote, if any, of the share of common stock (or fraction thereof) in respect of which such share of Series F Preferred Stock (or fraction thereof) was issued as a dividend is cast on the Reverse Stock Split, the Adjournment Proposal or such other matter, as applicable, and the proxy or ballot with respect to shares of common stock held by any holder on whose behalf such proxy or ballot is submitted will be deemed to include all shares of Series F Preferred Stock (or fraction thereof) held by such holder. Holders of Series F Preferred Stock will not receive a separate ballot or proxy to cast votes with respect to the Series F Preferred Stock on the Reverse Stock Split, the Adjournment Proposal or any other matter brought before any meeting of stockholders held to vote on the Reverse Stock Split. All shares of Series F Preferred Stock that are not present in person or by proxy at any meeting of stockholders held to vote on the Reverse Stock Split and the Adjournment Proposal as of immediately prior to the opening of the polls at such meeting (the “Initial Redemption Time”) will automatically be redeemed in whole, but not in part, by the Company at the Initial Redemption Time without further action on the part of the Company or the holder of shares of Series F Preferred Stock (the “Initial Redemption”). Any outstanding shares of Series F Preferred Stock that have not been redeemed pursuant to an Initial Redemption will be redeemed in whole, but not in part, (i) if such redemption is ordered by the Board in its sole discretion, automatically and effective on such time and date specified by the Board in its sole discretion or (ii) automatically upon the approval by the Company’s stockholders of the Reverse Stock Split at any meeting of the stockholders held for the purpose of voting on such proposal (the “Subsequent Redemption” and, together with the Initial Redemption, the “Redemption”). As of December 31, 2022, both the Initial Redemption and the Subsequent Redemption have occurred. As a result, no shares of Series F Preferred Stock remain outstanding. Each share of Series F Preferred Stock redeemed in any redemption described above will be redeemed in consideration for the right to receive an amount equal to $0.10 in cash for each one hundred whole shares of Series F Preferred Stock that are “beneficially owned” by the “beneficial owner” (as such terms are defined in the Certificate of Designation) thereof as of the applicable redemption time and redeemed pursuant to such redemption, payable upon receipt by the Company of a written request submitted by the applicable holder to the corporate secretary of the Company (each a “Redemption Payment Request”) following the applicable redemption time. Such Redemption Payment Request shall (i) be in a form reasonably acceptable to the Company (ii) set forth in reasonable detail the number of shares of Series F Preferred Stock beneficially owned by the holder at the applicable redemption time and include evidence reasonably satisfactory to the Company regarding the same, and (iii) set forth a calculation specifying the amount in cash owed to such Holder by the Company with respect to the shares of Series F Preferred Stock that were redeemed at the applicable redemption time. However, the redemption consideration in respect of the shares of Series F Preferred Stock (or fractions thereof) redeemed in any redemption described above: (i) will entitle the former beneficial owners of less than one hundred whole shares of Series F Preferred Stock redeemed in any redemption to no cash payment in respect thereof and (y) will, in the case of a former beneficial owner of a number of shares of Series F Preferred Stock (or fractions thereof) redeemed pursuant to any redemption that is not equal to a whole number that is a multiple of one hundred, entitle such beneficial owner to the same cash payment, if any, in respect of such redemption as would have been payable in such redemption to such beneficial owner if the number of shares (or fractions thereof) beneficially owned by such beneficial owner and redeemed pursuant to such redemption were rounded down to the nearest whole number that is a multiple of one hundred (such, that for example, the former beneficial owner of 150 shares of Series F Preferred Stock redeemed pursuant to any redemption will be entitled to receive the same cash payment in respect of such redemption as would have been payable to the former beneficial owner of 100 shares of Series F Preferred Stock redeemed pursuant to such redemption). No shares of Series F Preferred Stock may be transferred by the holder thereof except in connection with a transfer by such holder of any shares of common stock held by such holder, in which case a number of one one-thousandths (1/1,000ths) of a share of Series F Preferred Stock equal to the number of shares of common stock to be transferred by such holder will be automatically transferred to the transferee of such shares of common stock. The holders of Series F Preferred Stock, as such, are not entitled to receive dividends of any kind. The Certificate of Designation was filed with the Delaware Secretary of State and became effective on September 14, 2022. As described in the proxy statement filed on October 31, 2022, holders of The Company’s common stock and Series F Preferred Stock as of the close of business on October 17, 2022, are entitled to vote on the amendment to the Company’s Certificate of Incorporation to effect, at the discretion of the Company’s Board but prior to the six-month anniversary of the date on which the reverse stock split is approved by the Company’s stockholders at the Annual Meeting, a reverse stock split of all of the outstanding shares of the Company’s common stock at a ratio in the range of 1-for-2 to 1-for-50, with such ratio to be determined by the Board in its discretion and included in a public announcement, and the proposal to adjourn the Annual Meeting to a later date at the Annual Meeting held on December 15, 2022. Stock-based compensation and options During the years ended December 31, 2022 and 2021, 1,256 and 0 employee options were exercised, and 21,875 and 43,875 options were granted, respectively. The options granted during 2022 and 2021 vest at different schedules ranging from date granted to 9 years and were recorded at fair values of $201 and $583, respectively. During the years ended December 31, 2022 and 2021, stock-based compensation expense of $148 and $258 was recorded for options that vested, respectively. SCHEDULE OF OPTIONS ACTIVITY

As of December 31, 2022, the total unrecognized estimated compensation cost related to non-vested stock options granted prior to that date was $328, which is expected to be recognized over a weighted average period of approximately 7.24 years. Warrants On December 2, 2020, we entered into a Securities Purchase Agreement with certain institutional and accredited investors pursuant to which the Company issued and sold to such investors in a private placement an aggregate of (i) 295,714 shares of the Company’s common stock at an offering price of $14.00 per share and (ii) pre-funded warrants to purchase up to 132,857 shares of common stock at a purchase price of $13.98 per pre-funded warrant, for gross proceeds of approximately $6.0 million, and net proceeds of approximately $5.4 million. In January 2021, two investors exercised an aggregate of 82,857 warrants at $0.02 per share. On January 21, 2021, Company entered into letter agreements (the “Letter Agreements”) with certain existing accredited investors to exercise certain outstanding warrants (the “Existing Warrants”) to purchase up to an aggregate of 60,298 shares of the Company’s common stock at an exercise price per share of $23.30 (the “Exercise”). Certain of the Existing Warrants (the “Registered Existing Warrants”) and the shares of common stock underlying the Registered Existing Warrants have been registered pursuant to a registration statement on Form S-3 (File No. 333-251264) and a registration statement on Form S-1 (File No. 333-218871). In consideration for the exercise of the Existing Warrants for cash, the exercising holders received new unregistered warrants to purchase up to an aggregate of 60,298 shares of common stock (the “New Warrants”) at an exercise price of $20.80 per share and with an exercise period of seven years from the initial closing date. The gross proceeds to the Company from the Exercise were approximately $1.4 million. The New Warrants were accounted for in warrant modification expense, which was measured at the amount equal to the incremental value reflecting the change in the fair value of the warrants before and after the Warrant Amendment. Accordingly, warrant modification expense in the amount of $1,627 was recorded with a corresponding increase in additional paid in capital. In August and September 2021, investors exercised warrants to purchase 109,675 shares of common stock between $17.60 and $50.00 per share for proceeds of approximately $3.6 million. On June 14, 2022, the Company issued warrants to two sales consultants to purchase 12,500 shares of common stock which will expire on June 14, 2029 and have an exercise price of $20.00 per share. Accordingly, expense related to these warrants in the amount of $135,000 was recorded with a corresponding increase in additional paid in capital. On September 30, 2022, the Company and the two sales consultants mutually agreed to cancel the latter’s annual stock warrants to purchase 12,500 shares of common stock. Accordingly, expense related to these warrants were reversed in the amount of $135,000 with a corresponding decrease in additional paid in capital. On November 29, 2022, the Company granted 18,000 warrants to purchase Company’s common stock in conjunction with the private placements. In estimating the warrants’ fair value, the Company used the following assumptions: SCHEDULE OF FAIR VALUE ASSUMPTIONS FOR WARRANTS
