Common Stock [Abstract] |
Common Stock | Note 4 - Common Stock On September 25, 2020, the Company completed an initial public offering (“Offering”) of 3,000,000 shares of its common stock, $0.0001 par value per share, at an offering price of $5.00 per share (total net proceeds of approximately $12.8 million after underwriting discounts, commissions, and other offering costs). In connection with the Offering, the Company agreed to issue five (5) year warrants to the underwriter to purchase five percent (5%) of the number of common shares sold in the Offering for an exercise price equal to $6.00. Total warrants of 150,000 were issued to the underwriter on September 29, 2020. The Company measures the warrants using the Black Scholes Model (“BSM”) to estimate their fair value. The fair value of the warrants issued in connection with the Offering was approximately $249,000 based on the following inputs and assumptions using the BSM: (i) expected stock price volatility of 45.00%; (ii) risk free interest rate of .14%; and (iii) expected life of the warrants of 5 years. The warrants were fully vested on the date of grant and are included in offering costs in the Statement of Stockholders’ Equity. In connection with the Offering, the Company converted its outstanding convertible notes payable into 1,127,872 shares of its common stock. Additionally, in connection with the Offering, the Company cancelled 126,532 warrants previously issued to nonemployees in exchange for professional services to meet certain offering listing requirements, of which 6,665 were replaced and deemed vested in full. As a result, the Company recorded approximately $15,000 of additional warrant expense, which was recorded as additional paid-in-capital. On November 3, 2020 and December 14, 2020, the Company issued 69,709 shares of its common stock totaling approximately $290,000 and 106,383 shares of its common stock totaling approximately $500,000 in value, respectively, to various consulting firms in exchange for strategic investor relations services. These shares vested immediately upon issuance. In June 2021, the Company issued an additional 39,437 shares of its common stock totaling approximately $220,000 to a consulting firm for strategic investor relations services. These shares vested immediately upon issuance. During fiscal year 2021, warrant holders exercised 834,544 warrants on a cashless basis and received 488,728 shares of common stock. On August 2, 2021, the Company entered into a purchase agreement (the “Purchase Agreement”), with Lincoln Park Capital Fund, LLC (“Lincoln Park”), under which, subject to specified terms and conditions, the Company may sell to Lincoln Park up to $16.5 million worth of common stock, par value $0.0001 per share, from time to time during the term of the Purchase Agreement, which ends August 2, 2023. In connection with the Purchase Agreement, the Company entered into an introducing broker agreement with Laidlaw & Company (UK) Ltd. (“Laidlaw”), pursuant to which the Company agreed to pay a cash fee to Laidlaw (the “Introductory Fee”) equal to (i) 8% of the amount of the Initial Purchase, (ii) 8% of the amount of a one-time share request up to $1,000,000 (“Tranche Purchase”), if any, and (iii) 4% of up to the next $13,500,000 (or up to $14,500,000 if the Tranche Purchase is not exercised). Upon entering into the Purchase Agreement, the Company sold 759,109 shares of common stock to Lincoln Park as an initial purchase for a total purchase price of $1,500,000 (the “Initial Purchase”). The Company received net proceeds from the Initial Purchase of $1,360,000 after the payment of the Introductory Fee and offering costs. As consideration for Lincoln Park’s commitment to purchase up to $16.5 million of shares of common stock under the Purchase Agreement, the Company issued 152,715 shares of common stock to Lincoln Park. If Lincoln Park is requested to purchase additional shares during the term of the Purchase Agreement, the requested shares, (“Regular Purchase”), are limited based on the current share price of the Company’s common stock. If the average price is below $3.00 per share, the Company is limited to issuing 50,000 shares per request; if the share price is between $3.00 and $4.00 per share, the limit is 75,000 shares per request, if the share price is between $4.00 and $5.00, the limit is 100,000 shares per request, and if the share price is above $5.00, the limit is 150,000 shares per request. Requests for purchases are permitted daily as long as the Company’s stock price is above $0.50 per share. The price for such regular purchases will be the lower of: (i) the lowest closing price of the Company’s common stock on the purchase date for such Regular Purchase and (ii) the arithmetic average of the three (3) lowest closing prices of the Company’s common stock during the ten (10) consecutive business days immediately preceding. Additionally, the Company may instruct Lincoln Park to purchase additional shares of common stock that exceed the Regular Purchase limits (“Accelerated Purchase”). If the Company requests Lincoln Park to make an Accelerated Purchase, the price per share is discounted from average historical closing prices. No additional shares were sold to Lincoln Park in the year ended June 30, 2022. The Company evaluated the contract that includes the right to require Lincoln Park to purchase additional shares of common stock in the future (“put right”) considering the guidance in ASC 815-40, “Derivatives and Hedging - Contracts on an Entity’s Own Equity” (“ASC 815-40”) and concluded that it is an equity-linked contract that does not qualify for equity classification, and therefore requires fair value accounting. The Company has analyzed the terms of the put right and has concluded that it has no value as of June 30, 2022. On October 19, 2021 and December 2, 2021, the Company issued 9,901 shares of its common stock totaling approximately $18,218 and 4,000 shares of its common stock totaling approximately $4,480 in value, respectively, to various consulting firms in exchange for strategic investor relations services. These shares vested immediately upon issuance. During the fourth quarter of fiscal year 2022, the Company issued 250,000 of its common stock totaling approximately $126,250 in value, respectively, to a consulting firm in exchange for strategic advisory and digital marketing services. These shares vested immediately upon issuance. On February 11, 2022, the Company entered into an underwriting agreement with Laidlaw, as representative of the several underwriters, to issue and sell up to 3,437,500 shares of the Company’s common stock, at a public offering price of $0.80 per share. On February 14, 2022, the Company entered into an amended and restated underwriting agreement in order to increase the number of shares sold in the offering to 3,750,000. On February 16, 2022, the Company closed the offering, and sold 3,750,000 shares of common stock to Laidlaw for total gross proceeds of $3,000,000. After deducting the underwriting commission and expenses, the Company received net proceeds of approximately $2,509,550. In connection with the offering, the Company issued five (5) year warrants to the underwriter to purchase 187,500 common shares at an exercise price of $1.00. The Company measures the warrants using the BSM to estimate their fair value. The fair value of the warrants issued in connection with the offering was approximately $94,165 based on the following inputs and assumptions using the BSM: (i) expected stock price volatility of 80.10%; (ii) risk free interest rate of 1.63%; and (iii) expected life of the warrants of 5 years. The warrants were fully vested on the date of grant and are included in offering costs in the Statement of Stockholders’ Equity.
