At-The-Market Offering Program

On August 8, 2022, the Company entered into an Equity Distribution Agreement (as supplemented by side letters entered into on August 8, 2022 and on October 5, 2022, the “ATM Sales Agreement”) with Evercore Group L.L.C. ("Evercore") and H.C. Wainwright & Co., LLC (collectively, the "agents"), to sell shares of Common Stock having an aggregate sales price of up to $200.0 million, from time to time, through an “at-the-market offering” program under which the agents act as sales agents (the “ATM Offering”). The sales are made by any method permitted by law deemed to be an “at-the-market offering” as defined in Rule 415 promulgated under the Securities Act of 1933, as amended. The Company is not obligated to sell any shares of Common Stock under the ATM Sales Agreement and may at any time suspend solicitation and offers thereunder.

On October 5, 2022, the Company entered into a Side Letter to the ATM Sales Agreement, pursuant to which, notwithstanding the existence of outstanding balances under the PPA (refer to Note 9) as of October 5, 2022, but only for so long as any portion of such balance is outstanding, the agents agreed to allow the Company to submit orders to sell Common Stock of the Company under the ATM Sales Agreement beginning on October 5, 2022. In addition, pursuant to the Side Letter to the ATM Sales Agreement, during the period from October 5, 2022 until the beginning of the third business day after the Company files its Annual Report on Form 10-K for the fiscal year ended December 31, 2022: (i) only H.C. Wainwright may be designated as a Designated Manager under the ATM Sales Agreement and receive the entire compensation payable thereunder (equal to 3.0% of the gross proceeds of the shares of Common Stock sold), and (ii) for so
long as H.C. Wainwright acts as the sole Designated Manager, H.C. Wainwright agreed to waive the additional fee of 1.5% of the gross proceeds from any sales under the ATM Sales Agreement.

On February 28, 2023, Evercore delivered to us a notice to terminate the ATM Sales Agreement with respect to itself, which termination became effective on February 28, 2023.

During the three and six months ended June 30, 2023, the Company sold 1.9 million shares of Common Stock at prices ranging from $0.60 to $0.71 for net proceeds of $1.2 million under the ATM Offering.
Yorkville Standby Equity Purchase Agreement
On May 10, 2022, the Company entered into the SEPA with Yorkville. Pursuant to the SEPA, the Company could sell to Yorkville up to $250.0 million of its shares of Common Stock, at the Company’s request any time during the 36 months following the execution of the SEPA. Under the agreement, the Company issued 14.2 million shares of Common Stock to Yorkville, respectively, for cash proceeds of $32.5 million with a portion of the shares issued as non-cash stock purchase discount under the SEPA. Effective August 26, 2022, the Company terminated the SEPA. At the time of termination, there were no outstanding borrowings, advance notices, shares of Common Stock to be issued or fees due under the SEPA.

Other Issuances of Equity

On February 5, 2023, the Company entered into a securities purchase agreement ("SPA") with certain investors. The SPA provides for the sale and issuance by the Company of 50.0 million shares of the Company's Common Stock, together with warrants to purchase up to 50.0 million shares of Common Stock (the “SPA Warrants”) at a combined purchase price of $1.05 per share and accompanying warrants. The total net proceeds from the transaction was $49.4 million.

On February 5, 2023, the Company also issued warrants to purchase 2.0 million shares of our Common Stock (the “Placement Agent Warrants”) to our placement agent as part of the compensation payable for acting as our exclusive placement agent in connection with the SPA. The Placement Agent Warrants had the same terms as the warrants issued under the SPA. These warrants are equity classified and was measured at fair value on the issuance date. As of June 30, 2023, $1.6 million is reflected on the condensed consolidated statement of stockholders' equity as it relates to the issuance of these warrants.

The Company entered into other equity agreements including the Yorkville PPA and April Convertible Debenture discussed in Note 9, the May 2022 PIPE and June 2023 PIPE discussed in Note 12, and warrants issued to various parties discussed in Note 15.
