Note: Schedules filed in paper format shall include a signed original and five copies of the schedule, including all exhibits. See Rule 13d-7 for other parties to whom copies are to be sent.

*The remainder of this cover page shall be filled out for a reporting person’s initial filing on this form with respect to the subject class of securities, and for any subsequent amendment containing information which would alter disclosures provided in a prior cover page.

The information required on the remainder of this cover page shall not be deemed to be “filed” for the purpose of Section 18 of the Securities Exchange Act of 1934 (“Act”) or otherwise subject to the liabilities of that section of the Act but shall be subject to all other provisions of the Act (however, see the Notes).

This Amendment No. 9 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, by Amendment No. 6 filed on November 16, 2021, by Amendment No. 7 filed on January 10, 2023 and by Amendment No. 8 filed on February 17, 2023 (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. 9 to Schedule 13D is 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. 9 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. 9 to Schedule 13D is incorporated herein by this reference.

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 March 23, 2023, Heartland beneficially owned an aggregate of 729,300 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 13,358,075 shares outstanding, which is the total number of shares of Common Stock outstanding as of February 14, 2023, as reported in the Company’s Annual Report on Form 10-K, filed with the Securities and Exchange Commission on March 23, 2023.

As of March 23, 2023, as investment adviser to the Client Accounts, Heartland may be deemed the beneficial owner of 729,300 shares, or approximately 5.5%, 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 shares of Common Stock disclosed in this filing as owned by Heartland, HHI and Mr. Nasgovitz are owned by various Client Accounts managed by Heartland on a discretionary basis. To the best of Heartland’s knowledge, as of March 23, 2023, none of the 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 664,500 shares and shared dispositive power with respect to 729,300 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 664,500 shares of the Company’s Common Stock and shared dispositive power with respect to 729,300 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.

A description of any transactions in the Common Stock by Heartland on behalf of its clients during the past sixty (60) days from the date hereof is set forth on Annex 2 attached hereto and incorporated herein by reference.
