Amendment Description Inspired Entertainment, Inc. (“Inspired Entertainment” or the “Company”) is filing this Amendment No. 1 on Form 10-K/A (the “Amendment”) to its Annual Report on Form 10-K for the year ended December 31, 2025, originally filed with the Securities and Exchange Commission (the “SEC”) on March 10, 2026 (the “Original Report”). This Amendment is filed solely to correct a clerical error in the CBIZ CPAs P.C. audit opinion over the financial statements included in Item 8 of the Original Report, which incorrectly stated that CBIZ CPAs P.C. did not need to express an opinion over the effectiveness of the Company’s Internal Control Over Financial Reporting (“ICFR”). The correct audit opinion over ICFR was, in fact, properly included in the Original Report as required. Therefore, the audit opinion over the financial statements was updated accordingly (the “Amended Audit Opinion”). This Amendment includes Item 8. “Financial Statements and Supplemental Data” in its entirety and without change from the Original Report, other than the addition of the Amended Audit Opinion as the new page F-2, and the updating of page references.In accordance with Rule 12b-15 under the Securities Exchange Act of 1934, as amended, this Amendment also includes currently dated certifications from the Company’s principal executive officer and principal financial officer, as required by Sections 302 and 906 of the Sarbanes-Oxley Act of 2002. As required by the rules of the SEC, this Amendment sets forth an amended “Item 15. Exhibits, Financial Statement Schedules” in its entirety, which includes the currently dated certifications of the Company’s principal executive officer and principal financial officer as Exhibits 31.1, 31.2, 32.1 and 32.2 as well as a currently dated Exhibits 23.1 and 23.2, the consents of Marcum LLP and CBIZ CPAs P.C., the Company’s prior and current independent registered public accounting firms, respectively, with respect to this Amendment. This Amendment does not otherwise update any exhibits contained in the Original Filing.  This Amendment does not reflect events occurring after the Original Report and does not modify or update the disclosure therein in any way except as described above. No other changes have been made to the Original Report. Accordingly, this Amendment should be read in conjunction with the Original Filing and with the Company’s filings made with the SEC subsequent to the filing of the Original Filing, as information in such filings may update or supersede certain information contained in this Amendment.

Auditor Opinion [Text Block] We have audited the accompanying consolidated balance sheet of Inspired Entertainment, Inc, and Subsidiaries (the “Company”) as of December 31, 2025, the related consolidated statements of operations and comprehensive (loss) income, stockholders’ deficit and cash flows for the year ended December 31, 2025, and the related notes (collectively referred to as the “financial statements”). In our opinion, based on our audit, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025, and the results of its operations and its cash flows for the year ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America. 

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company’s internal control over financial reporting as of December 31, 2025, based on the criteria established in Internal Control – Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in 2013 and our report dated March 10, 2026, expressed an adverse opinion on the effectiveness of the Company’s internal control over financial reporting because of the existence of material weaknesses.
