Temporary Equity Disclosure [Abstract] |
Convertible Preferred Stock | 7. Convertible Preferred Stock In April 2018, the Company entered into the Series A Share Purchase Agreement (the “Series A SPA”), pursuant to which the investors committed to invest an aggregate amount of up to $60.0 million for the issuance of shares of Series A convertible preferred stock at a price of $1.00 per share in subsequent closings. Upon the completion of the Company’s IPO on November 13, 2019, there were 16,000,000 remaining shares of convertible preferred stock that were previously issuable that were no longer issuable. Accordingly, the preferred stock liability was extinguished and because the transaction occurred between related parties, the resulting $25.6 million was accounted for as a capital contribution by the preferred stockholders during 2019. Additionally, immediately prior to the completion of the Company’s IPO, all outstanding shares of convertible preferred stock automatically converted into 7,077,366 shares of common stock and the related carrying value was reclassified to common stock and additional paid-in capital.
