Amendment Description Global Asset Management Group, Inc. (the “Company,” “GAMG,” “we,” “us,” or “our”) is filing this Amendment No. 1 on Form 10-Q/A (this “Amendment”) to amend its Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2026, originally filed with the Securities and Exchange Commission on August 19, 2026 (the “Original Form 10-Q”). Subsequent to the filing of the Original Form 10-Q, the Company completed its accounting analysis relating to the consolidation of RI Property Holdings, Inc., including Memorial Real Estate Group LLC, and Sustainable Properties, LLC and its applicable subsidiaries and acquired entities. These acquisitions involved recently completed transactions and complex ownership, financing, and entity structures. At the time of the Original Form 10-Q, the Company had disclosed that management was continuing to evaluate the appropriate accounting treatment for these entities and related transactions. Following completion of that analysis, management determined that the applicable financial information of RI Property Holdings, Inc., Memorial Real Estate Group LLC, Sustainable Properties, LLC, and their applicable subsidiaries and acquired entities should have been included in the Company’s consolidated financial statements as of and for the three and six months ended June 30, 2026. Management evaluated the omission quantitatively and qualitatively and concluded that it resulted in a material misstatement of the Company’s previously issued unaudited condensed consolidated financial statements as of and for the three and six months ended June 30, 2026. Accordingly, the Company’s Board of Directors, upon the recommendation of the Audit Committee and after consultation with management, concluded that the financial statements included in the Original Form 10-Q should no longer be relied upon. This Amendment amends and restates Part I, Item 1, “Financial Statements,” Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and Part I, Item 4, “Controls and Procedures,” together with the related exhibits and certifications. The restated consolidated financial statements include the applicable financial information of RI Property Holdings, Inc., Memorial Real Estate Group LLC, Sustainable Properties, LLC, and their applicable subsidiaries and acquired entities. Except as expressly described in this Amendment, including the subsequent events disclosed in Note 12 and the remediation measures described in Part I, Item 4, this Amendment does not otherwise amend, update, or modify the disclosures contained in the Original Form 10-Q for events occurring after August 19, 2026. This Amendment should be read together with the Original Form 10-Q and the Company’s other filings with the Securities and Exchange Commission.
