Capital Structure | Note 13 — Capital Structure On January 9, 2020, the Company increased its authorized number of shares to 53,000,000, consisting of: 50,000,000 shares of common stock, par value $0.001 per share, and 3,000,000 shares of preferred stock, par value $0.001 per share. At that time, it also designated 100,000 shares of the 3,000,000 authorized shares of preferred stock, par value $0.001 per share, as Series A Convertible Preferred Stock (“Series A Preferred Stock”). Series A Convertible Preferred Stock Beginning in the first quarter of 2020, we issued an aggregate of 60,000 shares of our Series A Preferred Stock, for an aggregate purchase price of $6,000. In May 2020, we completed our offering of Series A Preferred Stock with the issuance of an additional 40,000 shares of Series A Preferred Stock for an aggregate purchase price of $4,000. Amendment of conversion formulas On January 11, 2021, the Company’s Board of Directors approved the amendment to the conversion formula of the Series A Preferred Stock and Notes. After the amendment: 1. the Series A Preferred Stock is convertible, at any time after issuance or immediately prior to the closing of a public transaction, into common stock in an amount of shares equal to (i) the product of the Series A Preferred Stock original price plus accrued but unpaid dividends on the shares being converted, multiplied by the number of shares of Series A Preferred Stock being converted, divided by (ii) a conversion price of $7.72 per share (after the reverse split taking effect) and 2. immediately prior to the consummation of a public transaction, the outstanding principal amount of the Notes together with all accrued and unpaid interest shall convert into a number of fully paid and non-assessable shares of common stock equal to the quotient of (i) the outstanding principal amount of the Notes together with all accrued and unpaid interest thereunder immediately prior to such public transaction divided by (ii) a conversion price of $7.72 (after the reverse split taking effect). On January 11, 2021, the Company’s shareholders approved the amendment to the Series A Preferred Stock. Initial Public Offering On February 1, 2021, the Company completed an initial public offering (“IPO”) for the sale of 5,400,000 shares of common stock at a price of $10.00 per share. The Company also granted the underwriters: (a) a 45-day option to purchase up to 810,000 additional shares of common stock on the same terms and conditions for the purpose of covering any over-allotments in connection with the IPO, and (b) warrants to purchase 162,000 shares of common stock (equal to 3% of the aggregate number of shares of common stock issued in the IPO) at an exercise price of $12.50 per share (which is equal to 125% of the IPO price). Subsequently, the underwriters exercised the over-allotment option, and on February 4, 2021, the Company closed on the sale of an additional 810,000 shares of common stock for a price of $10.00 per share and granted to the underwriters warrants to purchase 24,300 additional shares of common stock (equal to 3% of the amount of shares issued as part of the exercised of the over-allotment option) at an exercise price of $12.50 per share. The exercise of the over-allotment option brought the total number of shares of common stock sold by the Company in connection with the IPO to 6,210,000 shares and the total net proceeds received in connection with the IPO to approximately $57 million, after deducting underwriting discounts and estimated offering expenses. Immediately prior to the closing of our IPO, all outstanding shares of Series A Preferred Stock and Notes were converted into 1,373,038 shares of common stock and 1,697,075 shares of common stock, respectively, at a conversion price of $7.72 per share. Subsequent Public Offering On February 19, 2021, the Company consummated a secondary public offering (the “February Offering”) for the sale of 5,555,555 shares of common stock for a price of $13.50 per share. The Company also granted the underwriters: (a) a 45-day option to purchase up to 833,333 additional shares of common stock on the same terms and conditions for the purpose of covering any over-allotments in connection with the February Offering, and (b) warrants to purchase 166,667 shares of common stock (equal to 3% of the aggregate number of shares of common stock issued in the February Offering) at an exercise price of $16.875 per share (which is equal to 125% of the February Offering). Subsequently, the underwriters exercised the over-allotment option, and on March 22, 2021, the Company closed on the sale of an additional 833,333 shares of common stock for a price of $13.50 per share and granted to the underwriters warrants to purchase 25,000 additional shares of common stock (equal to 3% of the amount of shares issued as part of the exercised of the over-allotment option) at an exercise price of $16.875 per share. The exercise of the over-allotment option brought the total number of shares of common stock sold by the Company in connection with the February Offering to 6,388,888 shares and the total net proceeds received in connection with the February Offering to approximately $80 million, after deducting underwriting discounts and estimated offering expenses. Stock Option Plan On June 4, 2019, the Company adopted and approved the 2019 Stock Option Plan (the “2019 Plan”) which provided for the issuance of 1,743,744 shares of our common stock. On August 10, 2020 and October 8, 2020, the Company’s board of directors and stockholders, respectively, approved an increase to the maximum number of shares of common stock authorized for issuance over the term of the 2019 Plan from 1,743,744 shares to 3,355,083 shares. As of June 30, 2021, there are no shares available to be granted under the 2019 Plan. Prior to the consummation of the Company’s IPO, the Company cancelled the 2019 Plan and converted these stock options to the 2020 Plan, as more fully described below. Under the 2019 Plan, the standard vesting schedule provided that 25% of the options vest 12 months following issuance and the balance vests in 36 equal monthly installments thereafter. However, the Company’s board of directors was permitted to provide for alternative or accelerated vesting schedules in approving each stock option grant. In many cases, the Company’s board of directors included an accelerated vesting schedule under which 50% of the stock options granted vest immediately prior to a change of control transaction or the Company’s first underwritten public offering. 2020 Omnibus Equity Incentive Plan On December 18, 2020, the Company’s board of directors, and on January 11, 2021, the Company’s stockholders, adopted and approved the 2020 Omnibus Equity Incentive Plan (the “2020 Plan”), which replaced the 2019 Plan. The 2020 Plan provides for the grant of stock options, SARs, performance share awards, performance unit awards, distribution equivalent right awards, restricted stock awards, restricted stock unit awards and unrestricted stock awards to non-employee directors, officers, employees and nonemployee consultants of the Company or its affiliates. The aggregate number of shares of common stock that may be reserved and available for grant and issuance under the 2020 Plan is 4,533,732 shares. Shares will be deemed to have been issued under the 2020 Plan solely to the extent actually issued and delivered pursuant to an award. If any award granted under the 2019 Plan or the 2020 Plan expires, is cancelled, or terminates unexercised or is forfeited, the number of shares subject thereto is again available for grant under the 2020 Plan. The 2020 Plan shall continue in effect, unless sooner terminated, until the tenth (10 th On January 24, 2021, the Company’s Board of Directors approved grants of options to purchase an aggregate of 144,360 shares of common stock to its directors. The options will expire 10 years from the date of grant and have an exercise price per share of $4.86. 25% of the options vest 12 months following issuance and the balance vests in 36 equal monthly installments thereafter. On February 17, 2021, the Company’s Board of Directors approved grants of options to purchase an aggregate of 1,050,000 shares of common stock to its directors and employees. The options will expire 10 years from the date of grant and have an exercise price per share of $13.84. The options vest in 36 equal monthly installments from the date of grant. On February 18, 2021, the Company’s Board of Directors approved grants of options to purchase an aggregate of 10,000 shares of common stock to members of the Company’s Board of Advisors. The options will expire 10 years from the date of grant and have an exercise price per share of $14.49. The options were fully vested on the date of grant. On May 16, 2021, the Company’s Board of Directors approved grants of options to purchase an aggregate of 219,083 shares of common stock to its employees. The options will expire 10 years from the date of grant and have an exercise price per share of $7.68. 33.3% of the options vest 12 months following issuance and the balance vests in 24 equal monthly installments thereafter. The Company’s stock option compensation expense was $931 and $542 for the three months ended June 30, 2021 and 2020, respectively, and $3,066 and $603 for the six months ended June 30, 2021 and 2020, respectively. There was $10,125 of total unrecognized compensation cost related to unvested options granted under the Company’s options plans as of June 30, 2021. This stock option expense will be recognized through 2025. The fair value of each option is estimated on the date of grant using the Black-Scholes option-pricing model. This model incorporates certain assumptions for inputs including a risk-free market interest rate, expected dividend yield of the underlying common stock, expected option life and expected volatility in the market value of the underlying common stock. The following table summarizes the Company’s assumptions used in the valuation of options granted during the six months ended June 30, 2021: Volatility 40 % Risk-free interest rate 1.10% – 1.63 % Dividend yield 0.00 % 0% Expected life (years) 10 Forfeiture rate 0.00 % The Black-Scholes option-pricing model was developed for use in estimating the fair value of traded options, which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because the Company’s stock options and warrants have characteristics different from those of its traded stock, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of such stock options. The risk-free interest rate is based upon quoted market yields for United States Treasury debt securities with a term similar to the expected term. The expected dividend yield is based upon the Company’s history of having never issued a dividend and management’s current expectation of future action surrounding dividends. The Company calculates the expected volatility of the stock price based on the corresponding volatility of the Company’s peer group stock price for a period consistent with the underlying instrument’s expected term. The expected lives for such grants were based on the simplified method for employees and directors. In arriving at stock-based compensation expense, the Company estimates the number of stock-based awards that will be forfeited due to employee turnover. The Company’s forfeiture assumption is based primarily on its turn-over historical experience. If the actual forfeiture rate is higher than the estimated forfeiture rate, then an adjustment will be made to increase the estimated forfeiture rate, which will result in a decrease to the expense recognized in the Company’s financial statements. If the actual forfeiture rate is lower than the estimated forfeiture rate, then an adjustment will be made to lower the estimated forfeiture rate, which will result in an increase to expense recognized in the Company’s financial statements. The expense the Company recognizes in future periods will be affected by changes in the estimated forfeiture rate and may differ significantly from amounts recognized in the current period. As of June 30, 2021, there were 311,244 shares available to be granted under the Company’s 2020 Plan.
