Initial Public Offering

In July 2021, the Company closed its initial public offering (“IPO”) of its common stock in which the Company issued and sold 10,000,000 shares of its common stock, and sold an additional 1,500,000 shares of common stock upon the full exercise of the underwriters’ option to purchase additional shares of the Company's common stock.

Immediately prior to the closing of the IPO, all then-outstanding shares of redeemable convertible preferred stock were converted into 25,534,404 shares of common stock. Further, all outstanding redeemable convertible preferred stock warrants were converted into warrants to purchase 659,028 shares of common stock, which resulted in the reclassification of the convertible preferred stock warrant liability to additional paid-in capital.
