Preferred Stock

On June 11, 2020, the Company amended its certificate of incorporation to authorize the issuance of up to 10,000,000 shares of Preferred Stock. As of December 31, 2023, there was no preferred stock issued or outstanding.

Common Stock

On February 13, 2024, the Company amended its certificate of incorporation to effect a 1-for-80 reverse stock split of shares of the Company’s outstanding common stock, such that every 80 shares of common stock became one of common stock. The shares of common stock authorized for issuance remained unchanged at 500,000,000 and the par value per share of common stock remained unchanged at $0.001. Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s stockholders.

On December 1, 2023, the Company entered into an equity distribution agreement with Virtu Americas LLC to sell shares of the Company’s common stock, par value $0.001 per share, with aggregate gross sales proceeds of up to $50.0 million, from time to time, through an “at-the-market” equity offering program (the "ATM offering"). As of December 31, 2023, the Company has up to $47.5 million remaining in aggregate gross proceeds that can be issued through the ATM offering.
