Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

As previously disclosed, On May 19, 2026, 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 Quarterly Report on Form 10-Q for the period ended March 31, 2026 (the “Form 10-Q”) with the Securities and Exchange Commission (“SEC”) prior to May 18, 2026, 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-Q filing due date of May 18, 2026, to regain compliance with the NYSE American listing standards by filing the Form 10-Q and any subsequently delayed filings with the SEC.

The NYSE further noted that, if the Company fails to file the Form 10-Q within the six-month period, the NYSE may grant, at its sole discretion, an extension of up to six additional months for the Company to regain compliance, depending on the Company’s specific circumstances. The Delinquency Notification also provides that the NYSE may nevertheless commence suspension and delisting proceedings at any time if it deems that the circumstances warrant.

On June 12, 2026 the Company filed its Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2026 which was within to the NYSE American six-month Deadline.

On June 15, 2026, 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.
