AMENDMENT NO. 6 TO SCHEDULE 13D

Explanatory Note

This Amendment No. 6 (“Amendment No. 6”) amends and supplements the Schedule 13D (the “Original Schedule 13D”) filed on March 26, 2020, as amended by that certain Amendment No. 1 to the Original Schedule 13D (“Amendment No. 1”), filed on November 23, 2020, that certain Amendment No. 2 to the Original Schedule 13D (“Amendment No. 2”), filed on January 4, 2022, that certain Amendment No. 3 to the Original Schedule 13D (“Amendment No. 3”), filed on November 18, 2022, that certain Amendment No. 4 to the Original Schedule 13D (“Amendment No. 4”), filed on November 23, 2022, and by that certain Amendment No. 5 to the Original Schedule 13D (“Amendment No. 5”), filed on April 21, 2023, and as amended through this Amendment No. 6 (the “Schedule 13D”). The filing of this Amendment No. 6 represents the final amendment to this Schedule 13D and constitutes an exit filing for the Reporting Persons. Capitalized terms used but not otherwise defined herein shall have the respective meanings previously ascribed to them in the Schedule 13D.

Item 4.

Purpose of Transaction

Merger Agreement

On April 16, 2023, Acquisition Parent 0423 Inc., a Delaware corporation (“Parent”), Charah Solutions, Inc., a Delaware corporation (the “Company”), and Acquisition Sub April 2023, Inc., a Delaware corporation and a direct, wholly owned subsidiary of Parent (“Acquisition Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) providing for, among other things, the merger of Acquisition Sub with and into the Company (the “Merger”), as a result of which, the Company shall be the surviving corporation and shall continue its corporate existence under the laws of the State of Delaware as a wholly-owned subsidiary of Parent.

Pursuant to the terms of the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.01 per share, of the Company issued and outstanding immediately prior to the Effective Time (each, a “Share”), will be cancelled and each such Share held by the Reporting Persons will be cancelled and converted into the right to receive $6.00 per Share in cash, without interest (the “Common Per Share Merger Consideration”).

In addition, pursuant to the terms of the Merger Agreement, the shares of Series A Preferred Stock of the Company that are issued and outstanding immediately prior to the Effective Time shall be purchased and redeemed by Parent pursuant to Section 8 of the Certificate of Designations of Series A Preferred Stock for the aggregate amount of $39,803,755.05, and the shares of Series B Preferred Stock of the Company that are issued and outstanding immediately prior to the Effective Time shall be purchased and redeemed by Parent pursuant to Section 7 of the Certificate of Designations of Series B Preferred Stock for the aggregate amount of $30,000,000. Consequently, the Reporting Persons no longer beneficially own any shares of Series A Preferred Stock or Series B Preferred Stock.

Item 5. Interest in Securities of the Issuer

Items 5 (a)-(c) and (e) of the Schedule 13D are hereby amended and restated as follows:

As of the closing of the Merger on July 13, 2023, each of the Reporting Persons may have been deemed to have beneficial ownership of 0 Shares.

As of the closing of the Merger on July 13, 2023, each of the Reporting Persons may have been deemed to share the power to vote and direct the disposition of 0 Shares, which represented beneficial ownership of 0% of the Shares.

Except as set forth in this Schedule 13D, none of the Reporting Persons has effected any transaction in Common Stock during the past 60 days.

On the Closing Date, following the Merger, the Reporting Persons ceased to be the beneficial owner of more than five percent of the shares of Common Stock outstanding.
