Equity [Abstract] |
Stockholders’ Equity | 4. Stockholders’ Equity Preferred Stock The Company is authorized to issue a total of 10,000,000 shares of preferred stock, par value $0.0001 per share. On March 17, 2015, the Company filed a Certificate of Designations, Preferences, Rights and Limitations of its Series A Convertible Preferred Stock with the Delaware Secretary of State to amend the Company’s certificate of incorporation. The Company has designated a total of 350,000 shares as Series A Convertible Preferred Stock, which are non-voting and are not subject to increase without the written consent of a majority of the holders of the Series A Convertible Preferred Stock or as otherwise set forth in the Preferences, Rights and Limitations. The holders of each tranche of 175,000 shares of the Series A Convertible Preferred Stock are entitled to receive a per share dividend equal to 1% of the annual net revenue of the Company divided by 175,000, until converted or redeemed. As of June 30, 2021 and December 31, 2020, 9,650,000 shares of preferred stock were undesignated and may be issued with such rights and powers as the Board of Directors may designate. Each share of Series A Convertible Preferred Stock may be converted, at the option of the holder, into 2.0833 shares of common stock (subject to customary anti-dilution provisions) and the Series A Convertible Preferred Stock is subject to mandatory conversion at the conversion rate in the event of a merger or sale transaction resulting in gross proceeds to the Company of at least $21,875,000. The Series A Convertible Preferred Stock has a liquidation preference based on its assumed conversion into shares of common stock. The Series A Convertible Preferred Stock does not have a cash liquidation preference. If fully converted, the 350,000 outstanding shares of Series A Convertible Preferred Stock would convert into 729,167 shares of common stock at June 30, 2021 and December 31, 2020. The Company had the right to redeem the Series A Convertible Preferred Stock up to the fifth anniversary of their respective closing dates (March 17, 2015 and January 21, 2016) at a price per share equal to $50.00. Accordingly, as of December 31, 2020, the Company had the right to redeem the 175,000 shares of Series A Convertible Preferred Stock that were issued on January 21, 2016; however, that right expired on January 21, 2021. The Series A Convertible Preferred Stock has no right to cash, except with respect to the payment of the aforementioned dividend based on the generation of revenues by the Company. The shares of Series A Convertible Preferred Stock do not have any registration rights. Based on the attributes of the Series A Convertible Preferred Stock as previously described, the Company has accounted for the Series A Convertible Preferred Stock as a permanent component of stockholders’ equity. Common Stock The Company is authorized to issue a total of 100,000,000 shares of common stock, par value $0.0001 per share. As of June 30, 2021 and December 31, 2020, the Company had 13,663,260 shares and 12,402,157 shares, respectively, of common stock issued, issuable and outstanding. On November 30, 2020, the Company raised gross proceeds $5,700,000 through a public offering of 1,200,000 units at a sale price of $4.75 per unit. Each unit consists of one share of common stock and one warrant to purchase one share of common stock exercisable for five years at an exercise price of $5.70 per share. Additionally, on December 7, 2020, the Company received an additional $1,800 from the sale of 180,000 warrants as part of the overallotment option granted to the underwriters in the public offering. The warrants sold are exercisable for five years and represent the right to purchase one share of common stock at an exercise price of $5.70 per share. The total cash costs of the public offering were $1,110,451, resulting in net cash proceeds of $4,591,349. Pursuant to the underwriting agreement, the Company also granted to the underwriters warrants to purchase up to 120,000 shares of common stock commencing on May 24, 2021 and expiring on November 24, 2025, at an exercise price of $5.70 per share.
