All of the Common Stock that is beneficially owned by the Reporting Persons was acquired for investment purposes. The Reporting Persons may sell all or a portion of the shares of Common Stock now owned in the open market, in privately negotiated transactions or otherwise, at any time and from time to time and at such prices as the Reporting Persons deem advisable. The Reporting Persons intend to review their investment in the Issuer continually. Depending upon the results of such review and other factors that the Reporting Persons deem relevant to an investment in the Issuer, the Reporting Persons may take or propose to take, alone or in conjunction with others including the Issuer, other actions intended to increase or decrease the Reporting Persons’ investment in the Issuer or the value of their investment in the Issuer, which could include one or more of the transactions or actions referred to in paragraphs (a) through (j) of Item 4 of Schedule 13D.

Tom Allen and John Maldonado, each employees of Advent, serve as directors of the Issuer and were appointed to the Issuer’s board of directors as contemplated by the Stockholders’ Agreement.

In connection with the December 2020 Offering, the Advent Funds entered into a customary “lock-up” agreement with the Underwriters, dated December 1, 2020 (the “Lock-up Agreement”) pursuant to which the Advent Funds generally agreed, subject to certain exceptions, not to sell, transfer, or otherwise dispose of any shares of Common Stock or securities convertible into, or exchangeable or exercisable for, shares of Common Stock, for 30-days after the date of the final prospectus relating to the December 2020 Offering without prior written consent from the Underwriters.

The foregoing descriptions of the Underwriting Agreement and the Lock-up Agreements do not purport to be complete and are qualified in their entirety by reference to the full text of the Underwriting Agreement, a copy of which is attached as Exhibit 99.3, and a form of the Lock-up Agreements attached as Annex IV to the Underwriting Agreement, each of which is incorporated by reference herein.

The first sentence of Item 4 of Amendment No. 1 is hereby amended to replace “June 17, 2020” with “September 17, 2020.”

Item 5.
Interest in Securities of the Issuer

Item 5 of the Schedule 13D is supplemented as follows:

(a)(b) The responses of the Reporting Persons to Rows (7) through (13) of the cover pages of this Amendment No. 2 as of the close of business on December 3, 2020 are incorporated by reference herein. After giving effect to the sale of the shares of Common Stock described in Item 4 of this Amendment No. 2, as of the close of business on December 3, 2020, the Reporting Persons beneficially owned, in the aggregate, 15,418,795 shares of Common Stock, which represents approximately 14.84% of the Common Stock issued and outstanding.

The following table sets forth the aggregate number and percentage of the Common Stock beneficially owned by each Reporting Person as of the close of business on December 3, 2020, after giving effect to the sale of shares of Common Stock described in Item 4 of this Amendment No. 2, calculated in accordance with Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The percentage of Common Stock owned was calculated based on 103,920,013 shares of Common Stock outstanding following the completion of the December 2020 Offering (as defined in Item 4 of this Amendment No. 2), as reported in the December 2020 Prospectus Supplement.
