Initial Public Offering During 2016, the Company issued 72,125,000 shares of Series G Preferred Shares at a price of $0.80 per share, for net proceeds to the Company of approximately $57.4 million after deducting offering expenses payable by the Company. The same Series G investors agreed to purchase an additional $35.3 million of Series G Preferred Shares upon the Company’s achievement of a certain operational milestone, subject to limited closing conditions. In January 2019, May 2019, and August 2019, the Series G investors purchased additional Series G Preferred Shares, resulting in net proceeds to the Company of $24.7 million. In July of 2020, the Company issued 62,500,000 additional Series G Preferred Shares, at a price of $0.80 per share, for net proceeds to the Company of $49.8 million after deducting offering expenses payable by the Company. On May 31, 2016, holders of the requisite number of the Company’s then-outstanding convertible preferred stock approved the conversion of all preferred stock into shares of the Company’s common stock in connection with a new equity financing. Accordingly, all of the Company’s then-outstanding preferred stock was converted on a one-for-one basis into shares of the Company’s common stock. Under the terms of the equity financing, each prior holder of preferred stock who purchased a required amount of securities in the new financing was entitled to exchange certain of the shares of common stock received in the conversion described above into new prime series of preferred stock corresponding to the series of preferred stock from which the common stock was previously converted. All of the previously held Series A-1, B-1, C-1, D-1, E-1 and F preferred stock had similar features as the Series A-2 preferred stock (“Series A-2 Preferred Shares”), Series B-2 preferred stock (“Series B-2 Preferred Shares”), Series C-2 preferred stock (“Series C-2 Preferred Shares”), Series D-2 preferred stock (“Series D-2 Preferred Shares”), Series E-2 preferred stock (“Series E-2 Preferred Shares”), and Series F-2 preferred stock (“Series F-2 Preferred Shares”) described below. The Series A-2, Series B-2, Series C-2, Series D-2, Series E-2, Series F-2 and Series G Preferred Shares are referred to collectively as the “Preferred Shares.” On July 2, 2021, the Company closed its IPO of 8,050,000 shares of its common stock at a public offering price of $18.00 per share, which included 1,050,000 shares of common stock issued upon the exercise in full by the underwriters of their option to purchase additional shares, for net proceeds from the IPO, after deducting the underwriting discount and other offering expenses payable by the Company totaling $1.6 million, of $133.2 million. Upon the closing of the IPO, all shares of convertible preferred stock were automatically converted into common stock. Series G Preferred Shares were converted into common stock on a 15.819-for-1 basis, and all other shares of convertible preferred stock were automatically converted into common stock on a 39.548-for-1 basis. The conversion of the outstanding preferred stock resulted in an aggregate of 11,929,584 shares of common stock. Reverse Stock Split In connection with the IPO, the Company’s Board of Directors and stockholders approved a 1-for-39.548 reverse stock split of the Company’s common stock. The reverse stock split became effective on June 22, 2021. The par value of the common stock was not adjusted as a result of the reverse stock split. Adjustments corresponding to the reverse stock split were made to the ratio at which the convertible preferred stock will convert into common stock in connection with the closing of the IPO. Accordingly, all share and per-share amounts for all periods presented in these financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect the reverse stock split and the adjustment of the conversion ratio of the convertible preferred stock. Common Stock Warrants In connection with the IPO, the warrants to purchase shares of convertible preferred stock automatically converted into warrants to purchase common stock, resulting in the reclassification of the related convertible preferred stock warrant liability to additional paid-in capital. Upon the closing of the IPO these warrants to purchase convertible preferred stock became exercisable for 716,131 shares of common stock upon conversion at a weighted average exercise price of $2.39 per share.
