Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing. As previously disclosed, on January 3, 2025, Gencor Industries, Inc. (the “Company”) received a notice (the “Delinquency Notification”) from NYSE Regulation (the “NYSE”) indicating the Company was not in compliance with the NYSE American LLC (“NYSE American”) continued listing standards as a result of its failure to timely file its Annual Report on Form 10-K for the year ended September 30, 2024 (the “Form 10-K”) with the Securities and Exchange Commission (“SEC”) prior to December 31, 2024, the end of the extension period provided by Form 12b-25, and as a result was subject to the procedures set forth in Section 1007 of the NYSE American Company Guide. The NYSE informed the Company that, under the rules of the NYSE American, the Company had an initial six-month period from the Form 10-K filing due date of December 31, 2024, to regain compliance with the NYSE American listing standards by filing the Form 10-K and any subsequently delayed filings with the SEC. On June 10, 2025, the Company submitted an extension request to the NYSE, requesting additional time to regain compliance with the NYSE American continued listing standards. While the Company filed its Form 10-K on June 27, 2025, within the initial six-month period granted by the Delinquency Notification, the Company requested an extension to allow it additional time to coordinate the completion of the Quarterly Reports on Form 10-Q for the quarterly periods ended December 31, 2024 and March 31, 2025. On June 24, 2025, the Company received a letter from the NYSE, informing the Company that the NYSE accepted the extension request, granting the Company a plan period through August 19, 2025 (the “New Cure Deadline”) to submit its delinquent reports. The Company filed its Quarterly Reports on Form 10-Q for the quarterly periods ended December 31, 2024 and March 31, 2025 on July 25, 2025, which was prior to the New Cure Deadline. On July 25, 2025, the Company received a notification letter from the NYSE indicating that the Company has now regained compliance with Section 1007 of the NYSE American Company Guide and will be removed from the NYSE’s late filers’ list.   SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.       GENCOR INDUSTRIES, INC.
