Stockholders' equity, reverse stock split On July 26, 2023, the Company effected a 1-for-17 reverse stock split (the “Reverse Stock Split”) of its common stock. In accordance with the Reverse Stock Split, 17 pre-split shares of the Company’s common were automatically converted into one issued and outstanding post-split share. Proportional adjustments were also made to all outstanding stock options, pre-funded warrants, and common warrants in accordance with their respective terms. The Reverse Stock Split did not change the par value of the Company’s common stock or the authorized number of shares. No fractional shares were issued in connection with the Reverse Stock Split. All fractional shares were rounded up to the nearest whole share with respect to outstanding shares of common stock.
