Explanatory Note.

This Amendment No. 4 amends and supplements the Schedule 13D filed with the Securities and Exchange Commission on March 22, 2019 (the “Original Schedule 13D”), as amended by Amendment No. 1, which was filed with the Commission on May 3, 2021, Amendment No. 2, which was filed with the Commission on May 5, 2021, and Amendment No. 3, which was filed with the Commission on November 23, 2021. Capitalized terms used but not defined herein shall have the meanings ascribed to them in the Original Schedule 13D.

This Amendment is being filed to amend and supplement Items 4 and 5 as follows:

Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following to the section titled “Secondary Offering”:

As previously disclosed, on November 18, 2021, in connection with a registered secondary public offering (the “Secondary Offering”) of Common Stock, INEOS entered into an underwriting agreement (the “Underwriting Agreement”) among the Issuer, Citigroup Global Markets Inc. and Deutsche Bank Securities Inc., as representatives of the several underwriters listed on Schedule II thereto (the “Underwriters”), and the other selling stockholders listed on Schedule I thereto. As also previously disclosed, INEOS and the other selling stockholders agreed in the Underwriting Agreement to grant the Underwriters a 30-day option (the “Over-allotment Option”) to purchase up to 1,200,000 additional shares of Common Stock at a price of $9.12 per share. On December 17, 2021, the Underwriters notified INEOS that they were executing their right to purchase from INEOS an aggregate of 416,255 shares of Common Stock pursuant to the Over-allotment Option. The closing of such transaction occurred on December 20, 2021.

Item 5. Interest in Securities of the Issuer

(a) The percentage of the Issuer’s shares of Common Stock held is based on a statement of the Issuer in the prospectus supplement filed by the Issuer with the SEC on November 16, 2021 that there were 137,059,709 shares of Common Stock outstanding as of November 4, 2021. As of the close of business on December 20, 2021, INEOS beneficially owned 24,731,385 shares of Common Stock, which constituted approximately 18.0% of the Common Stock outstanding. James A. Ratcliffe, as the majority owner of INEOS Limited, may be deemed to be the beneficial owner of, and to have the power to vote and dispose of, the 24,731,385 shares of Common Stock held by INEOS. Neither the filing of this Statement on Schedule 13D nor any of its contents shall be deemed to constitute an admission by Mr. Ratcliffe that he is the beneficial owner of any of the Common Stock referred to herein for purposes of Section 13(d) or 13(g) of the Securities Exchange Act of 1934, as amended, or for any other purpose, and such beneficial ownership is expressly disclaimed except to the extent of his pecuniary interest therein.

(b) For each person listed, the following table indicates the number of shares of Common Stock as to which there is sole power to vote or to direct the vote, shared power to vote or to direct the vote, sole power to dispose or to direct the disposition and shared power to dispose or to direct the disposition:

Reporting Person	Sole Voting Power	Shared Voting Power	Sole Dispositive Power	Shared Dispositive Power
INEOS Limited	0	24,731,385	0	24,731,385
James A. Ratcliffe	0	24,731,385	0	24,731,385

(c) Except for the Underwriting Agreement, and the transactions contemplated by the Underwriting Agreement, none of INEOS, Mr. Ratcliffe or, to the knowledge of either INEOS or Mr. Ratcliffe, any person named on Exhibit A to the Original Schedule 13D has effected any transaction in the Common Stock during the past 60 days.

(d) Not applicable.

(e) Not applicable.
