This Schedule 13D/A constitutes Amendment No. 9 (this "Schedule 13D/A No. 9") to the original Schedule 13D dated June 17, 2014, as amended on October 28, 2014, February 16, 2016, May 21, 2019, May 4, 2020, May 3, 2023, April 3, 2024, January 3, 2025, and December 9, 2025 (as amended, the "Original Schedule 13D"), filed with the U.S. Securities and Exchange Commission (the "SEC") by Mr. Raymond C. Stachowiak, a member and the Executive Chairman of the board of directors (the "Board") of American Shared Hospital Services, a California corporation (the "Issuer"). The Original Schedule 13D reported Mr. Stachowiak's ownership of the Issuer's common stock, no par value (the "Common Stock"), both directly and indirectly through RCS Investments, Inc., an Illinois corporation ("RCS"), of which Mr. Stachowiak is the owner-president, and Stachowiak Equity Fund, LLC, an Illinois limited liability company ("Stachowiak Equity"), of which Mr. Stachowiak is the owner-manager. This Schedule 13D/A No. 9 also reports Mr. Stachowiak's indirect ownership of the Issuer's Common Stock through RCS/TIG Holdings LLC, a Delaware limited liability company ("RCS/TIG"; together with Mr. Stachowiak, RCS, and Stachowiak Equity, the "Reporting Persons," and each, a "Reporting Person"), of which Mr. Stachowiak is the owner-manager.
This Schedule 13D/A No. 9 is being filed to report the shares of Common Stock (the "Common Shares") that Mr. Stachowiak has acquired since filing Amendment No. 8 to the Original Schedule 13D with the SEC on December 9, 2025 (the "Schedule 13D/A No. 8"). This Schedule 13D/A No. 9 also updates the percentage of beneficial ownership reported for Stachowiak Equity, which immaterially decreased due to an increase in the Issuer's total number of issued and outstanding Common Shares since the Schedule 13D/A No. 8 was filed. Only those items that are hereby reported are amended; all other items reported in the Original Schedule 13D remain unchanged. Information given in response to each item shall be deemed incorporated by reference in all other items, as applicable.

Source of Mr. Stachowiak's Shares. The aggregate number of Common Shares reported as beneficially owned (the "Total Beneficial Ownership Amount") by Mr. Stachowiak in this Schedule 13 D/A No. 9 includes the Common Shares acquired or disposed of in the transactions described below that occurred since Mr. Stachowiak's reporting of beneficial ownership in the Schedule 13D/A No. 8.
On June 26, 2025, Mr. Stachowiak was granted an award of 110,000 RSUs (the "2025 RSUs"), of which 30,000 vested on each of June 27, 2025 and July 2, 2025, and 25,000 vested on each of October 1, 2025 and January 1, 2026. The Total Beneficial Ownership Amount reported for Mr. Stachowiak in this Schedule 13D/A No. 9 includes the 110,000 Common Shares underlying all 110,000 of the 2025 RSUs, which have all vested.
On March 26, 2026, Mr. Stachowiak was granted an award of 100,000 RSUs (the "2026 RSUs"), of which 25,000 vested on April 1, 2026, and 25,000 will vest on each of July 1, 2026, October 1, 2026, and January 1, 2027.

The 50,000 Common Shares underlying the remaining 50,000 RSUs that will vest on October 1, 2026 and January 1, 2027 have been excluded from Mr. Stachowiak's Total Beneficial Ownership Amount in this Schedule 13D/A No. 9 because such RSUs will not vest within 60 days of the Filing Date.
On or about May 14, 2026, Mr. Stachowiak conveyed 594,000 Common Shares previously owned directly by Mr. Stachowiak to RCS.
On June 20, 2026, 2,000 stock options granted to Mr. Stachowiak expired before being exercised.
