Redeemable Convertible Preferred Stock [Abstract] |
Redeemable Convertible Preferred Stock | 10. Redeemable Convertible Preferred Stock In March 2023, the Company issued 61,344,029 shares of Series F redeemable convertible preferred stock to existing and new investors at a price per share of $2.8505 for an aggregate cash consideration of $174.9 million, net of $5.9 million issuance costs. Contemporaneously with the issuance of the Series F redeemable convertible preferred stock, the Company converted all of the outstanding Convertible Notes issued by the Company from September 30, 2022 to December 16, 2022, in the aggregate principal amount of $40.0 million plus accrued, unpaid interest of $994,000 into 21,465,064 shares of Series F-1 redeemable convertible preferred stock at a price per share of $1.9098, which represents a discount of 33% from the cash purchase price per share. Additionally, in connection with the Series F redeemable convertible preferred stock financing, the cumulative dividends payable to holders of Series C redeemable convertible preferred stock upon a liquidation event were capped from $6.66 to $8.25 per share depending on the time of issuance, with an aggregate total of $88.5 million. The issuance of the Series F redeemable convertible preferred stock triggered the anti-dilution protection provision for Series B-1, Series B-2, Series C, Series D and Series E stockholders. As a result, the Company recorded a $26.8 million deemed dividend in the amount equal to the change in fair value of the abovementioned series of convertible preferred stock before and after the anti-dilution adjustment.
