Amendment Description This Amendment No. 1 to Form 10K (this “Amendment”) amends the Annual Report on Form 10-K of Noble Roman’s Inc (the “Company”) for the fiscal year ended December 31, 2025 (the “Original Filing”). The Company is filing this Amendment solely to correct a clerical error in the Report of Independent Registered Public Accounting Firm included in the Original Filing. Specifically, the report inadvertently reflected a report date of May 29, 2026, instead of the correct report date of June 5, 2026. This correction does not result in any changes to previously issued financial statements or auditor’s opinion thereon. Item 8 of Part II of the Original Filing is being amended and restated in its entirety to include the corrected Report of Independent Registered Public Accounting Firm, and this Amendment includes the applicable exhibits and certifications under Item 15 of Part IV. Except as described above, no other changes have been made to the Original Filing. The Company has not updated the disclosures contained therein to reflect any events occurring subsequent to the date of the Original Filing.
