Goldman Warrants

On February 4, 2019, the Company sold to Goldman Sachs & Co. LLC (the “Holder”), a Purchase Warrant for Common Shares (the “Warrant”) pursuant to which the Holder may purchase shares of the Company’s Common Stock in an aggregate amount of up to 404,634 shares (the “Warrant Shares”). The Warrant was sold to the Holder at a purchase price of $150,000, in a private placement exempt from registration under the Securities Act. The Warrant may be exercised by the Holder at any time after August 4, 2019 at an exercise price equal to $8.86 and expired on February 4, 2024. The value of the Warrant was $2.3 million and has been classified as an equity instrument in additional paid in capital in the Company’s Condensed Consolidated Balance Sheets.

On December 9, 2019, the Company entered into an Amendment No. 1 to the Warrant with Special Situations Investing Group II, LLC (as successor in interest to Goldman Sachs & Co. LLC) (the “Warrant Holder”) that increased the number of Warrant Shares issuable under the Warrant and to decrease the exercise price from $8.86 per share to $3.80 per share.

On June 16, 2020, the Company entered into an Amendment No. 2 to the Warrant with the Warrant Holder that increased the number of Warrant Shares issuable under the Warrant and decreased the exercise price from $3.80 per share to $2.61 per share. Amendment No. 2 also amends the Warrant such that the Per Share Anti-Dilution Price (as defined therein) is equal to the exercise price per share as provided in Amendment No. 2 to the Warrant.

As a result of the decreases in exercise price, the Company recorded additional debt discounts with a corresponding entry to additional paid in capital in the Condensed Consolidated Balance Sheets and Statements of Stockholders Equity. As of June 30, 2023, the Warrant Holder was permitted to purchase shares of the Company’s Common Stock in an aggregate amount of up to 463,067 warrant shares at an exercise price of $2.61 per share. The Warrants were cancelled on the Effective Date in accordance with the Plan.
