This Amendment No. 7 to Schedule 13D amends and supplements the Schedule 13D originally filed on July 27, 2016 (the "Original Schedule 13D") as amended by Amendment No. 1 filed on July 25, 2017 ("Amendment No. 1"), by Amendment No. 2 filed on August 30, 2017, by Amendment No. 3 filed on January 10, 2020, by Amendment No. 4 filed on January 13, 2021, by Amendment No. 5 filed on September 14, 2021 and by Amendment No. 6 filed on November 16, 2021 (the Original Schedule 13D, as so amended, the "Amended Schedule 13D") and is being filed jointly on behalf of Heartland Advisors, Inc., a Wisconsin corporation ("Heartland"), Heartland Holdings, Inc. ("HHI"), a Wisconsin corporation and William R. Nasgovitz, an individual (each a "Reporting Person," and together, the "Reporting Persons"), relating to the common stock, $0.001 par value per share (the "Common Stock), of Perma-Fix Environmental Services, Inc., a Delaware corporation (the "Company"). The purpose of this Amendment No. 7 to Schedule 13D is to update the Reporting Persons identified in Item 2, to update Annex 1 and other information set forth in Item 2 and to update Heartland's ownership of Common Stock on behalf of client accounts.

Unless otherwise defined or modified below, capitalized terms used in this Amendment No. 7 to Schedule 13D shall have the meaning ascribed to them in the Original Schedule 13D.

All disclosure for items contained in the Amended Schedule 13D where no new information is provided for such item in this Amendment No. 7 to Schedule 13D is incorporated herein by this reference.

**Item 2. Identity and Background**

Item 2 of the Amended Schedule 13D is hereby deleted and replace with the following:

This Amended Schedule 13D is being jointly filed by Heartland, HHI and William R. Nasgovitz.

Heartland is an investment adviser registered with the SEC that provides investment advisory services to Heartland Group, Inc., a registered investment company, as well as private investment advisory clients (collectively, the "Client Accounts"). As investment adviser to the Client Accounts, Heartland has the authority to invest the funds of the Client Accounts in securities (including shares of Common Stock of the Company) as well as the authority to purchase, vote and dispose of securities (including shares of Common Stock of the Company), and may thus be deemed the beneficial owner of the shares of the Company's Common Stock held by Heartland on behalf of the Client Accounts.

HHI is the parent holding company of Heartland and files this Schedule solely as the parent company of Heartland and indirect beneficial owner of the Common Stock held by Heartland.

Mr. William R. Nasgovitz is the Chief Executive Officer as well as a director and control person of Heartland. By virtue of his control of Heartland, Mr. Nasgovitz may be deemed to have a beneficial interest in the shares of the Company's Common Stock held by Heartland on behalf of the Client Accounts. Mr. Nasgovitz does not own any Common Stock for his own account and disclaims beneficial ownership of the shares of Common Stock reported herein. Information called for by Items 2-6 of Schedule 13D, if applicable, regarding the executive officers and directors of Heartland and HHI is set forth on Annex 1 attached hereto and incorporated herein by reference.

Heartland is a Wisconsin corporation. HHI is a Wisconsin corporation. Mr. Nasgovitz is a U.S. citizen. The principal business office address of Mr. Nasgovitz, HHI and Heartland is 790 North Water Street, Suite 1200, Milwaukee, WI 53202.

None of the Reporting Persons has, during the past five years, been convicted of any criminal proceeding (excluding traffic violations or similar misdemeanors).

None of the Reporting Persons has, during the last five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

**Item 3. Source and Amount of Funds or Other Consideration**

Item 3 of the Amended Schedule 13D is hereby deleted and replaced with the following:

Heartland has beneficially owned shares of Common Stock on behalf of Client Accounts for a number of years. As of December 31, 2022, Heartland beneficially owned an aggregate of 1,110,500 shares of the Company's Common Stock. All shares of Common Stock held by Heartland on behalf of the Client Accounts were purchased with funds provided by the Client Accounts.

**Item 5. Interest in Securities of the Issuer**

Item 5 of the Amended Schedule 13D is hereby deleted and replaced with the following:

The aggregate percentage of shares of Common Stock reported owned by each person named herein is based upon 13,324,756 shares outstanding, which is the total number of shares of Common Stock outstanding as of November 1, 2022, as reported in the Company's Quarterly Report on Form 10-Q, filed with the Securities and Exchange Commission on November 3, 2022.

As of December 31, 2022, as investment adviser to the Client Accounts, Heartland may be deemed the beneficial owner of 1,110,500 shares, or approximately 8.3%, of the Company's Common Stock. The clients of Heartland, a registered investment adviser, including a series of a registered investment company and other managed accounts, have the right to receive or the power to direct the receipt of dividends and proceeds from the sale of shares of the Company's Common Stock held by Heartland included in this Schedule 13D. The Heartland Value Fund, a series of Heartland Group, Inc., a registered investment company, owns greater than 5% of the Common Stock of the Company. Any remaining shares of Common Stock disclosed in this filing as owned by Heartland, HHI and Mr. Nasgovitz are owned by various other Client Accounts managed by Heartland on a discretionary basis. To the best of Heartland's knowledge, as of December 31, 2022, none of the other Client Accounts owns more than 5% of the shares of the Company's Common Stock outstanding.

Heartland, as investment adviser to the Client Accounts, may be deemed to have shared voting power with respect to 1,015,500 shares and shared dispositive power with respect to 1,110,500 shares of Common Stock. HHI, as parent company of Heartland, and Mr. Nasgovitz, as a control person of Heartland, may each be deemed to have shared voting power with respect to 1,015,500 shares of the Company's Common Stock and shared dispositive power with respect to 1,110,500 shares and may thus be deemed the indirect beneficial owner of the shares beneficially owned by Heartland. Mr. Nasgovitz specifically disclaims beneficial ownership of such shares.
