Capital Structure Capital Structure
 
Pursuant to the Company’s amended and restated certificate of incorporation, the Company is authorized to issue two classes of stock, common stock and preferred stock. At June 30, 2023, the total number of shares of capital stock the Company was authorized to issue was 205,000,000, of which 200,000,000 was common stock and 5,000,000 was preferred stock. All shares of common and preferred stock have a par value of $0.001 per share.

Common Stock

Exchange Agreement

In May 2023, the Company entered into an exchange agreement (the “Exchange Agreement”) with entities affiliated with Venrock Healthcare Capital Partners (“Venrock”), pursuant to which the Company exchanged an aggregate of 1.3 million shares of the Company’s common stock, par value $0.001 per share, owned by Venrock for pre-funded warrants (the “Exchange Warrants”) to purchase an aggregate of 1.3 million shares of common stock (subject to adjustment in the event of stock splits, recapitlizations and other similar events affecting common stock), with an exercise price of $0.001 per share. The Exchange Warrants are exercisable at any time, except that the Exchange Warrants will not be exercisable by Venrock if, upon giving effect or immediately prior thereto, Venrock would beneficially own more than 9.99% of the total number of issued and outstanding common stock, which percentage may change at the holders’ election to any other number less than or equal to 19.99% upon 61 days’ notice to the Company. The holders of the Exchange Warrants will not have the right to vote on any matter except to the extend required by Delaware law. In accordance with ASC No. 505, Equity, the Company recorded the retirement of the common stock exchanged as a reduction of
common shares outstanding and a corresponding impact to additional paid-in-capital and accumulated deficit at the fair value of the Exchange Warrants on the issuance date. The Exchange Warrants were classified as equity in accordance with ASC 480 and the fair value of the Exchange Warrants was recorded as a credit to additional paid-in-capital and is not subject to remeasurement. The Company determined that the fair value of the Exchange Warrants is substantially similar to the fair value of the retired shares on the issuance date due to the negligible exercise price for the Exchange Warrants. As of June 30, 2023, none of the Exchange Warrants have been exercised.

At-the-Market Offering Program

In May 2023, the Company entered into an “at-the-market” sales agreement with Oppenheimer & Co. Inc. (“Oppenheimer”), pursuant to which the Company may sell from time to time, shares of its common stock having an aggregate offering price of up to $9,032,567 through Oppenheimer. In the second quarter of 2023, the Company sold approximately 2.0 million shares under the ATM program for net proceeds of approximately $6.5 million.

Subsequent to June 30, 2023 and as of the filing date of this Quarterly Report on Form 10-Q, the Company sold an additional 6.2 million shares under the ATM program for gross proceeds of approximately $1.3 million.

Q1 2023 Financing

On February 7, 2023, the Company closed an underwritten public offering of 3,770,000 shares of its common stock and warrants to purchase up to 3,770,000 shares of common stock, at a combined price to the public of $3.98 per share and warrant, resulting in net proceeds of approximately $13.7 million, after deducting the underwriting discounts and commissions and offering expenses paid by us. The warrants were immediately exercisable at an exercise price of $5.00 per share and are exercisable for one year from the issuance date. Armistice, who was a significant stockholder of the Company at the time of the financing, participated in the offering by purchasing 0.5 million shares of common stock and 0.5 million warrants, on the same terms as all other investors. Certain affiliates of Nantahala Capital Management LLC and Point72 Asset Management, L.P., which each beneficially owned greater than 5% of the Company’s outstanding common stock at the time of the offering, participated in the offering on the same terms as all other investors.

The warrants were classified as a component of permanent stockholders’ deficit within additional paid-in capital. The warrants are equity classified because they (i) are freestanding financial instruments that are legally detachable and separately exercisable from the equity instruments, (ii) are immediately exercisable, (iii) do not embody an obligation for the Company to repurchase its shares, (iv) permit the holders to receive a fixed number of shares of common stock upon exercise, (v) are indexed to the Company’s common stock and (vi) meet the equity classification criteria. In addition, such warrants do not provide any guarantee of value or return.
