Amendment Description	EXPLANATORY NOTE This Amendment No. 2 on Form 10-K/A (this "Form 10-K/A") amends our Annual Report on Form 10-K for the fiscal year ended December 31, 2025, originally filed with the U.S. Securities and Exchange Commission (the "SEC") on March 31, 2026, as amended by Amendment No. 1 on Form 10-K/A filed with the SEC on April 20, 2026 (as amended, (the "2025 Form 10-K"). We are filing this Form 10-K/A to amend and restate the Exhibit Index (including the filing of new certifications as required by Section 302 of the Sarbanes-Oxley Act of 2002, as amended, in accordance with Rule 13a-14(a) under the Securities Exchange Act of 1934, as amended) in Item 15 of Part IV of the 2025 Form 10-K to include new Exhibits 10.20 and 10.25, and to include the information required by Items 10 through 14 of Part III that were not included in the 2025 Form 10-K, as we will not file a definitive proxy statement containing such information within 120 days after the end of the fiscal year ended December 31, 2025. Our board of directors has not yet set a date for the Company's 2026 Annual Meeting of Stockholders (the "Annual Meeting"). This Form 10-K/A amends and restates in their entirety Items 10 through 14 of Part III and the Exhibit Index (including the filing of new certifications as required by Section 302 of the Sarbanes-Oxley Act of 2002, as amended (the "Sarbanes-Oxley Act") in accordance with Rule 13a-14(a) under the Securities Exchange Act of 1934, as amended (the "Exchange Act") of the 2025 Form 10-K. Except as otherwise expressly noted above, this Form 10-K/A does not amend any other information set forth in the 2025 Form 10-K. This Form 10-K/A continues to speak as of the date of the 2025 Form 10-K and, except where expressly noted, we have not updated disclosures contained herein or therein to reflect any events that occurred at a date subsequent to the date of the 2025 Form 10-K. Accordingly, this Form 10-K/A should be read in conjunction with the 2025 Form 10-K and our other filings with the SEC. Because no financial statements have been included in this Form 10-K/A and this Form 10-K/A does not contain or amend any disclosure with respect to Item 307 or Item 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications required by Section 302 of the Sarbanes-Oxley Act have been omitted. Unless the context requires otherwise, all references to the "Company," "Reading," “we,” “our” or “us” means Reading International, Inc., a Nevada corporation, and its consolidated subsidiaries.
