Subsequent Events | 15. Subsequent Events 2021 Equity Incentive Plan On July 27, 2021, the Company’s board of directors adopted, and on July 29, 2021 its stockholders approved, the 2021 Equity Incentive Plan (the “2021 Plan”), which became effective immediately prior to and contingent upon the execution of the underwriting agreement related to the Company’s IPO. The 2021 Plan provides for the grant of incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock awards, restricted stock units and other stock-based awards. The number of shares reserved for issuance under the 2021 Plan is initially equal to 35,075,122, which is the sum of 11,413,572 new shares; plus the number of shares (not to exceed 23,661,550 shares), which represents (i) the number of shares that remained available for issuance under the 2020 Plan, at the time the 2021 Plan became effective, and (ii) any shares subject to outstanding stock options or other stock awards that were granted under the 2020 Plan that are forfeited, terminate, expire or are otherwise not issued. In addition, the number of shares of the Company’s common stock reserved for issuance under the 2021 Plan will automatically increase on the first day of each calendar year, beginning on January 1, 2022 and continuing through January 1, 2031, in an amount equal to 5% of the shares of common stock outstanding on the last day of the calendar month before the date of each automatic increase, or a lesser number of shares determined by the board of directors. The shares of common stock underlying any awards that are forfeited, cancelled, held back upon exercise or settlement of an award to satisfy the exercise price or tax withholding, repurchased or are otherwise terminated by the Company under the 2021 Plan will be added back to the shares of common stock available for issuance under the 2021 Plan. 2021 Employee Stock Purchase Plan On July 27, 2021, the Company’s board of directors adopted, and on July 29, 2021 its stockholders approved, the 2021 Employee Stock Purchase Plan (the ‘‘2021 ESPP’’), which became effective immediately prior to and contingent upon the execution of the underwriting agreement related to the Company’s IPO. A total of 1,342,773 shares of common stock were initially reserved for issuance under this plan. The number of shares of common stock that may be issued under the 2021 ESPP will automatically increase on the first day of each calendar year, beginning on January 1, 2022 and continuing through January 1, 2031, by an amount equal to the lesser of (i) 1% of the shares of common stock outstanding on the last day of the calendar month before the date of each automatic increase, (ii) 2,685,546 shares and (iii) an amount determined by the Company’s board of directors. Stock Split On July 30, 2021, the Company effected a five-for-one stock split of its issued and outstanding shares of common stock and a proportional adjustment to the existing conversion ratios of each series of the Company’s preferred stock (see Note 8). Accordingly, all share and per share amounts for all periods presented in the accompanying condensed consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect this stock split and adjustment of the Preferred Stock conversion ratios. Initial Public Offering On August 10, 2021, the Company completed its IPO, pursuant to which it issued and sold 20,930,000 shares of its common stock, including 2,730,000 shares of its common stock pursuant to the full exercise of the underwriters’ option to purchase additional shares. The aggregate net proceeds received by the Company from the IPO were approximately $330.9 million, after deducting underwriting discounts and commissions, but before deducting estimated offering expenses payable by the Company, which are estimated to be $3.8 million. Upon the closing of the IPO, all of the shares of the Company’s convertible preferred stock then outstanding converted into 84,722,420 shares of common stock. Upon the conversion of the convertible preferred stock, the Company reclassified the carrying value of the convertible preferred stock to common stock (at par value) and additional paid-in capital. Increase in Authorized Number of Shares of Common Stock and Changes in Authorized Preferred Stock On July 30, 2021, the Company filed an amended and restated certificate of incorporation, which increased the Company’s authority to issue (i) 150,000,000 shares of common stock and (ii) 16,944,484 shares of Preferred Stock. On August 10, 2021, in connection with the closing of the IPO, the Company filed a restated certificate of incorporation, which amended and restated the Company’s certificate of incorporation to, among other things: (i) increase the number of authorized shares of common stock from 19,000,000 shares to 1,000,000,000 shares, (ii) eliminate all references to the previously existing series of convertible preferred stock, and (iii) authorize 10,000,000 shares of undesignated preferred stock that may be issued from time to time by the Company’s board of directors in one or more series. Research Collaboration and License Agreement with The Scripps Research Institute In August 2021, the Company entered into a Research Collaboration and License Agreement (the “Research Agreement”) with The Scripps Research Institute (“TSRI”). Under the terms of the Research Agreement, TSRI will perform research activities (the “Research Program”) to identify vaccine candidates for the prevention, diagnosis or treatment of influenza or beta coronaviruses (the “Field”). Unless otherwise mutually agreed by the parties, the Research Program will be completed by August 2023. Activities initiated under the Research Agreement for targets or indications pursued under the arrangement will be conducted in accordance with a research plan to be agreed upon by the parties (each, a “Research Plan”). The Company is obligated to provide the research funding necessary to carry out the Research Program pursuant to the budget outlined in each Research Plan. As of June 30, 2021, the Company paid TSRI $1.5 million in pre-paid funding, which will be credited against any research funding payable by the Company under the Research Agreement. Additionally, the Company is obligated to make specified payments to TSRI to the extent that TSRI complies with certain exclusivity covenants. Pursuant to the terms of the Research Agreement, the Company was granted an exclusive option (the Option) to acquire an exclusive, worldwide, sublicensable license under TSRI’s rights in certain patent rights and know-how for the exploitation of any vaccine product containing, comprised of, or derived from, any vaccine candidate identified or developed under the Research Program (each, a “TSRI Licensed Product”) in the Specified Field. Any licenses granted under the arrangement are subject to certain exceptions, conditions and reserved rights. The Company’s option is exercisable for a predefined period of time as outlined in the arrangement. Upon exercise of the Option, the Company is required to reimburse certain patent costs previously incurred by TSRI and bear all future related patent costs. Following the exercise of the Option, the Company has the sole right and responsibility for the further development and potential commercialization of the associated Licensed Product, at its sole cost and expense. To the extent any Licensed Product covered by the Research Agreement is commercialized, the Company is obligated to pay TSRI royalties of a low single-digit percentage on a Licensed Product-by-Licensed Product and country-by-country basis based on a percentage of net sales, subject to reduction and floor. The Research Agreement will expire (i) when no further royalties are due to TSRI or (ii) twelve years from the first commercial sale of the Licensed Product, whichever is longer. The Company may terminate the Research Agreement at any time upon advance written notice to TSRI. In addition, TSRI may terminate the Research Agreement in the event of a material breach. Following expiration or termination, all licenses will terminate and revert to TSRI, all sublicenses granted by the Company will automatically terminate, and any then-existing sublicensees will have the right to obtain a direct license from TSRI. Milestone Achievements under the Adimab Assignment Agreement In August 2021, the Company dosed the first patient in a Phase 3 global clinical trial evaluating ADG20 for the prevention of COVID-19, which resulted in a milestone payment of $4.0 million being due by the Company under the Adimab Assignment Agreement. The $4.0 million milestone will be expensed in the third quarter of 2021. |
