14. | STOCKHOLDERS’ EQUITY
In July 2021, the Company issued and sold an aggregate of 2,875,000 registered shares of its common stock (including 375,000 shares sold pursuant to the exercise of the underwriters' overallotment option) at a price of $21.00 per share. The net proceeds to the Company, after deducting $4.4 million in underwriting discounts and commissions, and offering expenses, were approximately $56.0 million. The Company intends to use the net proceeds from this offering for working capital and other general corporate purposes. On April 9, 2021, the Board of Directors declared a dividend in the amount of $750 per share of Series A Convertible Preferred Stock, par value $0.001 per share, outstanding at the close of business on April 12, 2021 (the record date), in the aggregate amount of $1.0 million. In connection therewith, the Company and each holder of Series A Convertible Preferred Stock agreed that effective April 15, 2021, the Series A Convertible Preferred Stock, plus accrued unpaid dividends thereon be converted to 4,636,649 shares of common stock, with an additional 695,498 shares of common stock issued in exchange for all accrued and unpaid dividends. Reverse Stock Split On April 27, 2021, the Company effected a 1-for-10 reverse stock split. All owners of record as of April 27, 2021 received one issued and outstanding share of the Company’s common stock in exchange for 10 outstanding shares of the Company’s common stock. No fractional shares were issued in connection with the reverse stock split. All fractional shares created by the one-for-ten exchange were rounded down to the next whole share, with cash paid in lieu of fractional shares. The reverse stock split had no impact on the par value per share of the Company’s common stock, which remains at $0.001. All share and per share information has been retroactively adjusted to reflect the impact of the Reverse Stock Split. Series A Preferred Stock Effective April 8, 2020, the Company exchanged an aggregate of approximately $7.0 million of all its then-outstanding notes, representing principal and accrued interest through April 7, 2020, for 1,391 shares Series A Preferred Stock. The shares of Series A Preferred Stock were recorded at fair value of $11.6 million (before reduction of $0.029 million related to issue costs) based on a per share fair value of $0.008 million. The per share fair value was determined using the number of common stock shares in a conversion (3,333 = $0.005 million original issue price divided by $1.50 conversion price) multiplied by the $2.50 market price of a share of common stock. Each share of Series A Preferred Stock had a $0.005 million issue price. Dividends accrued on the issue price at a rate of 10.0% per annum and were payable to holders of Series A Preferred Stock when and if declared by the Board. The dividends were cumulative and accrued starting from the April 8, 2020 issuance date. Each share of Series A Preferred Stock was convertible into the number of shares of common stock equal to the issue price divided by the conversion price of $1.50. Upon conversion of the Series A Preferred Stock, all accrued and unpaid dividends were converted to common stock utilizing the same conversion formula. The conversion price was subject to proportional adjustment for certain transactions relating to the Company’s common stock, including stock splits, stock dividends and similar transactions. Then holders of Series A Preferred Stock were entitled to a liquidation preference in the event of any liquidation, dissolution or winding up of the Company. Warrants Warrant Issuances in 2020 Upon the April 2020 closing of the exchange of convertible notes for shares of shares Series A Preferred Stock, in accordance with the security purchase agreements, as amended, pursuant to which the convertible notes were issued, the Company issued 149,842 warrants to the holders reflecting 400 warrants for each $1,000 of unpaid interest accrued on the Notes. The Warrants were exercisable for one share of common stock at an exercise price of $2.50 per share on or before either October 22, 2023 (for Warrants issued for interest accrued on convertible notes issued in October 2019, April 2019 and May 2019) or January 22, 2024 (for warrants issued for interest accrued on convertible notes issued in July 2019 and September 2019 and related January 2020 Notes). As the transaction was accounted for as a debt extinguishment (See Note 14, “Convertible Notes Payable” for additional information), the warrants were recorded at fair value of $0.2 million using a Monte Carlo simulation model. During January 2020, the Company issued 49,842 warrants to those note holders who returned interest checks and accepted payment in kind of units consisting of convertible notes with a face value of $0.1 million together with 400 warrants for every $1,000 of accrued interest to satisfy $0.1 million of accrued interest that was payable through October 31, 2019. The warrants were each exercisable for one share of common stock at an exercise price of $2.50 per share on or before October 22, 2023. During February 2020, the Company also issued 15,000 warrants as payment to a consultant for marketing services. The warrants were each exercisable for one share of common stock at an exercise price of $2.50 per share on or before February 5, 2021. See Note 15, “Stock-Based Compensation,” for additional information. The assumptions that the Company used to determine the grant-date fair value of warrants granted for the years ended November 30, 2020 were as follows: (Black-Scholes option pricing model)

Exercise price |  |  | $2.50 |  |
Warrants Exercises in 2020: Based on the Company’s stock price, provisions allowing for early termination of outstanding warrants issued in connection with the Company’s October 2018 financing were triggered on October 23, 2020. On October 25, 2020, the Company notified holders of the October 2018 warrants exercisable at $2.50 that it was exercising its early termination right and that the respective warrants would expire November 27, 2020. Between October 25, 2020 and November 27, 2020, holders of 189,079 warrants issued during the October 2018 financing and outstanding as of October 25, 2020 exercised warrants for 189,079 shares of common stock, generating approximately $0.5 million. Based on the Company’s stock price, provisions allowing for early termination of two issuances of outstanding warrants issued in connection with the Company’s 2017 financing were triggered on May 29, 2020 and June 1, 2020, respectively. On June 3, 2020, the Company notified holders of 57,235 warrants exercisable at $1.50 that it is exercising its early termination right and that the respective warrants would expire July 3, 2020. On June 8, 2020, the Company notified holders of 1,777,388 warrants exercisable at $1.80 that it was exercising its early termination right and that the respective warrants would expire on August 31, 2020. Between June 1, 2020 and August 31, 2020, all holders of these 1,834,623 warrants issued during the 2017 financing and outstanding as of June 1, 2020 exercised those warrants for 1,834,623 shares of common stock, generating approximately $3.3 million. An additional 99,261 warrants that were issued in connection with the Company’s 2018 and 2019 private placements and exercisable at $2.50 were also exercised between June 1 and August 31 of 2020 for 99,261 shares of common stock, raising approximately $0.2 million. In addition, in July 2020 a former consultant exercised 75,000 warrants exercisable at $1.55 pursuant to an agreement with the Company providing for cashless exercise of those warrants and resulting in the issuance of 68,319 shares of common stock.

The warrant exercise price was reduced from $2.50 to $1.60 per warrant to induce warrant holders to exercise. The Company recorded warrant inducement expense of $0.8 million during the year ended November 30, 2020, which represents the difference between fair value at the reduced price of $1.60 per warrant and fair value at the contractual price of $2.50. The fair values of the warrants at $1.60 and $2.50 were determined using a Monte Carlo simulation model. Warrant Exercises in 2021 During the year ended November 30, 2021, the Company raised $1.3 million through warrant exercises, where 510,739 warrants were exercised at a contractual price of $2.50 per warrant for 510,739 shares of common stock.
