Stockholders' Equity Note [Abstract] |
Stockholders' Equity | NOTE 8. STOCKHOLDERS’ EQUITY Share Recapitalization prior to the Merger The consolidated statement of stockholders’ equity has been retroactively adjusted for all periods presented to reflect the Merger and reverse capitalization as discussed in Note 3, Merger. In connection with the Merger, all issued and outstanding Redeemable Series A Convertible Preferred Stock (discussed below) were exchanged for the Company’s Class A common stock pursuant to the Exchange Ratio in the Merger. The following discussion of share recapitalization occurred in 2020 prior to the Merger. On November 20, 2020, the Company amended its certificate of incorporation authorizing the issuance of three classes of stock designated as “Class A Common Stock”, “Class B Common Stock” and “Series A Preferred Stock”, respectively. As a result of the amended certificate of incorporation, each share of common stock issued and outstanding prior to the amendment was automatically reclassified and became one issued and fully paid share of Class A Common Stock. Immediately following the reclassification, the Company’s founder (“Founder”) exchanged 281,130,898 shares of the newly classified Class A Common Stock and 12,963,780 shares of Series A Preferred Stock owned into 294,094,678 shares of newly issued Class B Common Stock. The terms of the Stock Restriction Agreement, as discussed below, continues to apply to an equal number of shares Class B Common Stock. The holder of the Class B Common Stock had the option to convert each share into one fully paid share of Class A Common Stock at any time. Upon the earlier of the date (i) the Founder of the Company owns in aggregate fewer than 220,571,000 shares of Common Stock, (ii) the Founder no longer serves as the Company’s Chief Executive Office or (iii) the Founder’s death or disability, each share of Common B Common Stock shall automatically convert to one fully paid share of Class A Common Stock and the Company shall not issue any additional shares of Class B Common Stock. Each share of Class B Common Stock shall automatically convert into one paid share of Class A Common Stock upon any sale or disposition of a share of Class B Common Stock. In the event of liquidation, holders of the Class A and Class B Common Stock are entitled to share ratably in all the Company assets, after liquidation preferences of the preferred stock are satisfied. As of December 31, 2020, two shareholders owned approximately 95% of the outstanding Class A common stock and the Founder owns 100% of the outstanding Class B common stock. Common Stock As discussed in Note 3, Merger, the Company has retroactively adjusted the shares issued and outstanding prior to October 27, 2020 to give effect to the Exchange Ratio established in the Merger Agreement to determine the number of shares of common stock into which they were converted. As of December 31, 2021, there are 216,948,568 shares of Class A Common Stock and 1,000,000 shares of Class B Common Stock outstanding. As of December 31, 2022, the Founder owns 100% of the outstanding Class B common stock. Class A Common Stock Issuance and Cancelation On March 26, 2021, the Company issued 368,408 fully paid shares of Class A Common Stock to a current common stockholder related to the final settlement of acquired in-process research and development pursuant to a prior asset acquisition agreement and concurrently acquired and retired without consideration the same number of shares of Class A Common Stock held by the Founder. The aggregate fair value for shares issued to current common stockholder is $3.8 million or $10.28 per share and classified as research and development expense on the Consolidated Statements of Operations and Comprehensive Loss, which represents payment of the contingent consideration for acquired in-process research development. The price per share of $10.28 is based on the Company’s closing stock price on March 26, 2021. Common Stock Restriction Agreement As a result of the Merger, the shares subject to the “Stock Restriction Agreement” between the Company and the Founder was adjusted based on the Exchange Ratio. The number of shares, as adjusted, subject to repurchase per the terms of the Stock Restriction Agreement is reduced each month by 1,101,240 Class A common shares and no common shares will be subject to repurchase by June 2022. As of December 31, 2022, there are no shares of Class A Common Stock subject to the repurchase option. Voting Holders of Class A and Class B common stock are entitled to one vote per share on all matters, except that the holders of Class A common stock do not participate in the election of the directors who are elected exclusively by the holders of Class B common stock. Holders of Class A and Class B common stock vote together as a single class on all matters, except that (i) the holders of Class B common stock have the right, voting as a separate class, to elect and remove without cause three directors plus at least 50% of any directors in excess of seven, and (ii) the approval of the holders of a majority of Class B common stock, voting as a separate class, is required for approval by the stockholders of any acquisition (whether by merger, sale of shares or sale of assets) or liquidation. There are no cumulative voting rights. Conversion Each share of Class B common stock will automatically convert into one share of Class A common stock upon transfer to a non-authorized holder. In addition, the Class B common stock is subject to a “sunset” provision under which all outstanding shares of Class B common stock will automatically convert into an equal number of shares of Class A common stock if ownership of shares of Class A and Class B common stock held by our President and Chief executive Officer, David Hung, M.D., falls below an aggregate of 43,188,000 shares or if Dr. Hung dies, becomes disabled or ceases to be our Chief Executive Officer, unless he is terminated from such position by us without cause.
