This Amendment No. 1 (the “Amendment”) amends and supplements the Schedule 13D filed by the Reporting Persons on June 7, 2023 (the “Original Schedule 13D” and, as amended and supplemented by this Amendment, the “Schedule 13D”), with respect to the Common Stock. Capitalized terms used in this Amendment and not otherwise defined shall have the same meanings ascribed to them in the Original Schedule 13D.

Item 4. PURPOSE OF TRANSACTION.

Item 4 of the Original Schedule 13D is hereby amended and supplemented as follows:

On July 24, 2023, pursuant to that certain Agreement and Plan of Merger, dated May 29, 2023 (the “Merger Agreement”), by and among the Issuer, SW ParentCo, Inc., a Delaware corporation (“Parent”), and SW MergerCo, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Merger Sub”), Merger Sub merged with and into the Issuer (the “Merger”), with the Issuer surviving the Merger as a wholly owned subsidiary of Parent.

Immediately prior to the effective time of the Merger, pursuant to the Contribution and Exchange Agreement, the Reporting Persons contributed 4,041,280 of their shares of Common Stock to Parent in exchange for shares of Series A-2 Preferred Stock, par value $0.001 per share, of Parent. In addition, The Jeremy and Hannelore Grantham Environmental Trust had held 6,241 shares of Class A Common Stock that were inadvertently excluded from the Original Schedule 13D. Those 6,241 shares of Class A Common Stock were tendered in the Offer for $0.30 per share of Class A Common Stock and acquired by Merger Sub on July 20, 2023.

Item 5. INTEREST IN SECURITIES OF THE ISSUER.

Item 5 of the Original Schedule 13D is hereby amended and restated in its entirety as follows:

The information contained in rows 7, 8, 9, 10, 11 and 13 on each of the cover pages of this Statement and the information included in Item 4 of this statement is incorporated by reference in its entirety into this Item 5.
