Equity [Abstract] |
STOCKHOLDERS’ EQUITY | NOTE 9 – STOCKHOLDERS’ EQUITY Series B Convertible Preferred Stock The following summary of certain terms and provisions of our Series B Convertible Preferred Stock (the “Series B Convertible Preferred Stock”) is subject to, and qualified in its entirety by reference to, the terms and provisions set forth in our certificate of designation of preferences, rights and limitations of Series B Convertible Preferred Stock (the “Series B Convertible Preferred Certificate of Designation”) as previously filed. Subject to the limitations prescribed by our articles of incorporation, our board of directors is authorized to establish the number of shares constituting each series of preferred stock and to fix the designations, powers, preferences, and rights of the shares of each of those series and the qualifications, limitations and restrictions of each of those series, all without any further vote or action by our stockholders. Our board of directors designated 15,000 of the 10,000,000 authorized shares of preferred stock as Series B Convertible Preferred Stock with a stated value of $1,000 per share. The shares of Series B Convertible Preferred Stock were validly issued, fully paid and non-assessable. Each share of Series B Convertible Preferred Stock was convertible at any time at the holder’s option into a number of shares of common stock equal to $1,000 divided by the conversion price of $7.00 per share. Notwithstanding the foregoing, we could not effect any conversion of Series B Convertible Preferred Stock, with certain exceptions, to the extent that, after giving effect to an attempted conversion, the holder of shares of Series B Convertible Preferred Stock (together with such holder’s affiliates, and any persons acting as a group together with such holder or any of such holder’s affiliates) would beneficially own a number of shares of our common stock in excess of 4.99% (or, at the election of the purchaser, 9.99%) of the shares of our common stock then outstanding after giving effect to such conversion. The Series B Convertible Preferred Certificate of Designation does not prohibit the Company from waiving this limitation. Upon any liquidation, dissolution or winding-up of the Company, whether voluntary or involuntary, the holders would be entitled to participate on an as-converted-to-common stock basis (without giving effect to the Beneficial Ownership Limitation) with holders of the common stock in any distribution of assets of the Company to the holders of the common stock. As of June 30, 2025 and December 31, 2024, respectively, there are zero 0 and zero 0 shares of Series B Convertible Preferred Stock issued and outstanding. Series C Convertible Preferred Stock The Company’s Board of Directors designated 5,000 shares as the Series C Convertible Preferred Stock (the “Series C Convertible Preferred Stock”). Each share of the Series C Convertible Preferred Stock had a stated value of $1,000. The holders of the Series C Convertible Preferred Stock, the holders of the common stock and the holders of any other class or series of shares entitled to vote with the common stock shall vote together as one class on all matters submitted to a vote of shareholders of the Company. Each share of Series C Convertible Preferred Stock had 172 votes (subject to adjustment); provided that in no event may a holder of Series C Convertible Preferred Stock be entitled to vote a number of shares in excess of such holder’s Beneficial Ownership Limitation (as defined in the Certificate of Designation and as described below). Each share of Series C Convertible Preferred Stock was convertible, at any time and from time to time, at the option of the holder, into that number of shares of common stock (subject to the Beneficial Ownership Limitation) determined by dividing the stated value of such share ($1,000) by the conversion price, which is $5.50 (subject to adjustment). The Company shall not effect any conversion of the Series C Convertible Preferred Stock, and a holder shall not have the right to convert any portion of the Series C Convertible Preferred Stock, to the extent that after giving effect to the conversion sought by the holder such holder (together with such holder’s Attribution Parties (as defined in the Certificate of Designation)) would beneficially own more than 4.99% (or upon election by a holder, 19.99%) of the number of shares of common stock outstanding immediately after giving effect to the issuance of shares of common stock issuable upon such conversion (the “Beneficial Ownership Limitation”). All holders of the Series C Convertible Preferred Stock elected the 19.99% Beneficial Ownership Limitation. At June 30, 2025 and December 31, 2024 there were zero 0 and zero 0 shares of Series C Convertible Preferred Stock, issued and outstanding, respectively. Series D Convertible Preferred Stock On September 28, 2022, the Company amended its articles of incorporation to designate 4,000 shares as the Series D Convertible Preferred Stock (the “Series D Convertible Preferred Stock”). Each share of the Series D Convertible Preferred Stock has a stated value of $1,000. The holders of the Series D Convertible Preferred Stock, the holders of the common stock and the holders of any other class or series of shares entitled to vote with the common stock shall vote together as one class on all matters submitted to a vote of shareholders of the Company. Each share of Series D Convertible Preferred Stock has 333 votes (subject to standard anti-dilution adjustment); provided that in no event may a holder of Series D Convertible Preferred Stock be entitled to vote a number of shares in excess of such holder’s Beneficial Ownership Limitation (as defined in the Certificate of Designation and as described below). Each share of Series D Convertible Preferred Stock is convertible, at any time and from time to time, at the option of the holder, into that number of shares of common stock (subject to the Beneficial Ownership Limitation) determined by dividing the stated value of such share ($1,000) by the conversion price, which is $3.00 (subject to adjustment). The Company shall not effect any conversion of the Series D Convertible Preferred Stock, and a holder shall not have the right to convert any portion of the Series D Convertible Preferred Stock, to the extent that after giving effect to the conversion sought by the holder such holder (together with such holder’s Attribution Parties (as defined in the Certificate of Designation)) would beneficially own more than 4.99% (or upon election by a holder, 19.99%) of the number of shares of common stock outstanding immediately after giving effect to the issuance of shares of common stock issuable upon such conversion (the “Beneficial Ownership Limitation”). All but one of the holders of the Series D Convertible Preferred Stock elected the 19.99% Beneficial Ownership Limitation. The Company shall reserve and keep available out of its authorized and unissued Common Stock, solely for the issuance upon the conversion of the Series D Convertible Preferred Stock, such a number of shares of Common Stock as shall from time to time be issuable upon the conversion of all of the shares of the Series D Convertible Preferred Stock then outstanding. Additionally, the Series D Convertible Preferred Stock does not have the right to dividends and in the event of an involuntary liquidation, the Series D Convertible Preferred Stock shall be treated as a pro rata equivalent of common stock outstanding at the date of the liquidation event and have no liquidation preference. On September 30, 2022, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with certain existing investors in the Company (the “Purchasers”).

In connection with such Purchase Agreements, the Company entered into Registration Rights Agreements and filed registration statements with the SEC covering the resale by the Purchasers of the shares of common stock into which the shares of Series D Convertible Preferred Stock are convertible. The Registration Rights Agreements contain customary representations, warranties, agreements and indemnification rights and obligations of the parties. The Registration Rights Agreements contain provisions for liquidated damages equal to 1% multiplied by the aggregate subscription amount paid, paid each month, in the event certain deadlines are missed. Series E Convertible Preferred Stock The Company’s Board of Directors has designated 30,000 shares as the Series E Convertible Preferred Stock (the “Series E Convertible Preferred Stock”). Each share of the Series E Convertible Preferred Stock has a stated value of $1,000. The holders of the Series E Convertible Preferred Stock, the holders of the common stock and the holders of any other class or series of shares entitled to vote with the common stock shall vote as one class on all matters submitted to a vote of shareholders of the Company. Each share of Series E Convertible Preferred Stock has 333 votes (subject to adjustment); provided that in no event may a holder of Series E Convertible Preferred Stock be entitled to vote a number of shares in excess of such holder’s Beneficial Ownership Limitation. Each share of Series E Convertible Preferred Stock is convertible at any time and from time to time, at the option of the holder, into that number of shares of common stock (subject to the Beneficial Ownership Limitation) determined by dividing the stated value of such share ($1,000) by the conversion price, which is $3.00 (subject to adjustment) (see adjustment below to $2.61). The Company shall not effect any conversion of the Series E Convertible Preferred Stock, and the holder shall not have the right to convert any portion of the Series E Convertible Preferred Stock, to the extent that after giving effect to the conversion sought by the holder such holder (together with such holder’s Attribution Parties (as defined in the Certificate of Designation)) would beneficially own more than 4.99% (or upon election by a holder, 19.99%) of the number of shares of common stock outstanding immediately after giving effect to the issuance of shares of common stock issuable upon such conversion (the “Beneficial Ownership Limitation”). All but one of the holders of the Series E Preferred Stock elected the 19.99% Beneficial Ownership Limitation. The Company on March 27, 2023 entered into a Securities Purchase Agreement (the “Purchase Agreement”) with an existing investor in the Company (the “Purchaser”). Pursuant to the Purchase Agreement, the Purchaser purchased 4,000 shares of a newly authorized Series E Convertible Preferred Stock at a price of $1,000 per share, and the Company received proceeds of $4,000,000. The Purchase Agreement contains customary representations, warranties, agreements and indemnification rights and obligations of the parties. The existing investor’s Purchase Agreement also provided that the Company would not, with certain exceptions, sell or issue common stock or Common Stock Equivalents (as defined in the Purchase Agreement) on or prior to December 31, 2023 that entitled any person to acquire shares of common stock at an effective price per share less than the then conversion price of the Series E Convertible Preferred Stock without the consent of the Purchaser. On November 9, 2023, the Company entered into a Securities Purchase Agreement (the “November Purchase Agreement”) with an existing investor in the Company (the “Purchaser”). Pursuant to the Purchase Agreement, the Purchaser purchased 2,500 shares of Series E Convertible Preferred Stock, at a price of $1,000 per share, and the Company received proceeds of $2,500,000. The November Purchase Agreement also provided that the Company would not, with certain exceptions, sell or issue common stock or Common Stock Equivalents (as defined in the November Purchase Agreement) on or prior to June 30, 2024 that entitled any person to acquire shares of common stock at an effective price per share less than the then conversion price of the Series E Convertible Preferred Stock, which was $3.00 per share, without the consent of the Purchasers. If the Company sold shares less than the then conversion price, with the consent of purchasers, then the Series E conversion price would be amended to that lower share price. This provision was not triggered as of June 30, 2024. The Purchasers under the November Purchase Agreement also were the holders of the Company’s Series F Convertible Preferred Stock issued on August 1, 2023. The purchase agreement relating to the shares of Series F Convertible Preferred Stock required the consent of the holders in the event the Company were to issue common stock or rights to acquire common stock prior to December 31, 2023 at an effective price per share less than the then conversion price of the Series F Convertible Preferred Stock, which was $6.20 per share. As a result, on November 10, 2023 the Company and the holders of the Series F Convertible Preferred Stock entered into Exchange Agreements pursuant to which the holders of Series F Convertible Preferred Stock exchanged their 5,000 shares of Series F Convertible Preferred Stock for an equal number of shares of Series E Convertible Preferred Stock.

On March 22, 2024 and March 28, 2024, the Company entered into Securities Purchase Agreements (the “Purchase Agreements”) with certain existing and other accredited investors (the “2024 Purchasers”). Pursuant to the Purchase Agreements, the 2024 Purchasers purchased an aggregate of 2,125 shares of Series E Convertible Preferred Stock, at a price in each case of $1,000 per share, and the Company received proceeds of $2,125,002. Those purchase agreements had similar price protections as the November Purchase Agreement but extended the price protection date to December 31, 2024, for all Series E holders. On September 19, 2024, the conversion price was lowered to $2.61 from $3.00 per share based on the down-round protection provision triggered by the warrants induced exercise price of $2.61 per share. This will lead to the issuance of an additional 678,640 shares of common stock upon the conversion of the preferred shares. In October 2024, 125 outstanding shares of the Series E Preferred Stock were converted into 47,892 shares of common stock. In May 2025, 1,000 shares of Series E Preferred Stock were converted into 383,143 shares of common stock. In connection with such Purchase Agreements, the Company also entered into Registration Rights Agreements with the Purchasers. Pursuant to the Registration Rights Agreements, the Company filed with the SEC registration statements covering the resale by the Purchasers of the shares of common stock into which the shares of Series E Convertible Preferred Stock are convertible. The Registration Rights Agreements contain customary representations, warranties, agreements and indemnification rights and obligations of the parties. The Registration Rights Agreements contain provisions for liquidated damages equal to 1% multiplied by the aggregate subscription amount paid, paid each month, in the event certain deadlines are missed.

Each share of Series F Convertible Preferred Stock was convertible, at any time and from time to time, at the option of the holder, into that number of shares of common stock (subject to the beneficial ownership limitation described below) determined by dividing the stated value of such share ($1,000) by the conversion price, which is $6.20 (subject to adjustment) which equates to 161 common shares for each converted Series F Convertible Preferred Share. The Company, however, shall not effect any conversion of the Series F Convertible Preferred Stock, and the holder shall not have the right to convert any portion of the Series F Convertible Preferred Stock, to the extent that after giving effect to the conversion sought by the holder such holder (together with such holder’s Attribution Parties (as defined in the Certificate of Designation)) would beneficially own more than 4.99% (or upon election by a holder, 19.99%) of the number of shares of common stock outstanding immediately after giving effect to the issuance of shares of common stock issuable upon such conversion. The purchasers of the Series F Convertible Preferred Stock elected that their ownership limitation would be 19.99%. The holders of the Series F Convertible Preferred Stock, the holders of the common stock and the holders of any other class or series of shares entitled to vote with the common stock shall vote together as one class on all matters submitted to a vote of shareholders of the Company. Each share of Series F Convertible Preferred Stock had 161 votes (subject to adjustment); provided that in no event may a holder of Series F Convertible Preferred Stock be entitled to vote a number of shares in excess of such holder’s ownership limitation. On August 2, 2023, the Company entered into a Securities Purchase Agreement (the “Purchase Agreement”) with an existing, accredited investor in the Company (the “Purchaser”). Pursuant to the Purchase Agreement, the Purchaser purchased 5,000 shares of a newly authorized Series F Convertible Preferred Stock, and the Company received proceeds of $5,000,000. The Purchase Agreement contains customary representations, warranties, agreements and indemnification rights and obligations of the parties. The Company also agreed that it would not, with certain exceptions, sell or issue common stock or Common Stock Equivalents (as defined in the Purchase Agreement relating to the Series F Convertible Preferred Stock) on or prior to December 31, 2023 that entitled any person to acquire shares of common stock at an effective price per share less than the then conversion price of the Series F Convertible Preferred Stock without the consent of the holders. As a result of that agreement, upon the issuance of 2,500 shares of Series E Convertible Preferred Stock (which had a conversion price of $3.00 per share) on November 10, 2023, the holders exchanged their 5,000 shares of Series F Preferred Stock for 5,000 shares of Series E Preferred Stock. All of the shares of Series F Convertible Preferred Stock thereupon were cancelled with 0 shares now outstanding. As of June 30, 2025 and December 31, 2024, respectively, there were zero 0 and zero 0 shares of Series F Convertible Preferred Stock issued and outstanding.

In connection with these issuances, the Company also recognized compensation expense of $40,589 during the six months ended June 30, 2024 Employee Stock Purchase Plan In the fourth quarter of 2022, the board of directors adopted an Employee Stock Purchase Plan (“ESPP”) which was effective as of January 1, 2023 with a term of 10 years. The ESPP allows eligible employees to purchase shares of the Company's common stock at a discounted price, through payroll deductions from a minimum of 1% and up to 25% of their eligible compensation up to a maximum of $25,000 or the IRS allowable limit per calendar year. The Company’s Chief Financial Officer administers the ESPP in conjunction with approvals from the Company’s Compensation Committee, including with respect to the frequency and duration of offering periods, the maximum number of shares that an eligible employee may purchase during an offering period, and, subject to certain limitations set forth in the ESPP, the per-share purchase price. Currently, the maximum number of shares that can be purchased by an eligible employee under the ESPP is 10,000 shares per offering period and there are two six-month offering periods that begin in the first and third quarters of each fiscal year. The purchase price for one share of Common Stock under the ESPP is currently equal to 85% of the fair market value of one share of Common Stock on the first trading day of the offering period or the purchase date, whichever is lower (look-back feature). Although not required by the ESPP, all payroll deductions received or held by the Company under the ESPP are segregated and deemed as “restricted cash” until the completion of the offering period and redemption of the applicable shares and those withheld amounts are recorded as liabilities. The maximum aggregate number of shares of the Common Stock that may be issued under the ESPP is 1,000,000 shares. Under ASC 718-50 “Employee Share Purchase Plans” the plan is considered a compensatory plan and the compensation for each six-month offering period is computed based upon the grant date fair value of the estimated shares to be purchased based on the estimated payroll deduction withholdings. The grant date fair value was computed as the sum of (a) 15% purchase discount off of the grant date quoted trading price of the Company’s common stock and (b) the fair value of the look-back feature of the Company’s common stock on the grant date which consists of a call option on 85% of a share of common stock and a put option on 15% of a share of common stock. The Company computed the fair value of the look-back feature call and put options for January 1, 2025 to June 30, 2025 using a Black Scholes option pricing model using the following assumptions:
