(the lenders under the Credit Agreement among the Company, certain of its affiliates as guarantors, Orion Energy Partners Investment Agent, LLC (the “Orion Agent”) and such lenders (as amended, the “Orion Credit Agreement”) for a $200.0 million senior secured credit facility (the “Orion Facility”)) (the “Selling Stockholders”) completed a public offering of the Company’s common stock. In connection with this public offering, the Company and the Selling Stockholders entered into an underwriting agreement pursuant to which (i) the Company agreed to issue and sell to the underwriters 19,822,219 shares of the Company’s common stock, plus up to 5,177,781 shares of common stock pursuant to an option to purchase additional shares, and (ii) the Selling Stockholders agreed to sell to the underwriters 14,696,320 shares of common stock, in each case at a price to the public of $6.50 per share. The underwriters exercised their option to purchase additional shares, resulting in the issuance and sale by the Company at the closing of the offering of a total of 25,000,000 shares of common stock. The offering closed on December 4, 2020.

Gross proceeds from the sale of common stock by the Company in the offering were $162.5 million. The Company did not receive any proceeds from the sale of common stock in the offering by the Selling Stockholders.

The Company and the Selling Stockholders paid underwriting discounts and commissions of $0.2275 per share, and net proceeds to the Company were approximately $156.4 million after deducting such underwriting discounts and commissions and other estimated offering expenses.

During fiscal year 2020, the lenders exercised all of the Orion Warrants, except for Orion Warrants to purchase 2,700,000 shares of common stock. On December 7, 2020, all remaining Orion Warrants were exercised to purchase a total of 2,700,000 shares of the Company’s common stock for an aggregate exercise price of $653,400 (or $0.242 per share).

The Orion Warrants that were converted on December 7, 2020 were remeasured to fair value immediately preceding the conversion based upon volatility of 117.02%, a risk free rate of 0.70% and the Company’s common stock price of $7.95 on December 4, 2020, which resulted in a $16.0 million charge for the three months ended January 31, 2021. The estimated fair value of the converted warrants as of the date of conversion of $21.2 million was reclassified to Additional paid in capital.

During the three months ended January 31, 2020, the lenders exercised, on a cashless basis, Orion Warrants representing the right to purchase 12,000,000 shares of the Company’s common stock. Because these Orion Warrants were exercised on a cashless basis, the Company issued in the aggregate 9,396,320 shares of the Company’s common stock. The Orion Warrants that were converted were remeasured to fair value immediately preceding the conversion based upon volatility of 103.7%, a risk free rate of 1.81% and the Company’s common stock price of $2.29 on January 8, 2020, which resulted in a $23.7 million charge for the three months ended January 31, 2020. The revised estimated fair value of the converted warrants as of the date of conversion of $26.0 million was reclassified to Additional paid in capital. The remaining warrants as of January 31, 2020 were remeasured to estimated fair value based upon a volatility of 104.9%, a risk free rate of 1.45% and the Company’s common stock price at January 31, 2020 of $1.59 per share, which resulted in a charge for the three months ended January 31, 2020 of $10.5 million.

On May 3, 2017, the Company completed an underwritten public offering that included the offering and sale of: (i) 1,000,000 shares of its common stock, and (ii) Series C warrants to purchase 1,000,000 shares of its common stock that have an exercise price of $19.20 per share and a term of five years. No Series C warrants were exercised during the three months ended January 31, 2021. The Series C warrants contain provisions regarding adjustments to their exercise price and the number of shares of common stock issuable upon exercise.
