Amendment Description FDCTech, Inc. (the “Company”) is filing this Amendment No. 3 on Form 10-K/A (this “Amendment No. 3”) to its Annual Report on Form 10-K for the fiscal year ended December 31, 2025, originally filed with the Securities and Exchange Commission (the “SEC”) on April 17, 2026 (the “Original Form 10-K”), as amended by Amendment No. 1 on Form 10-K/A filed with the SEC on April 22, 2026 (“Amendment No. 1”), and as further amended by Amendment No. 2 on Form 10-K/A filed with the SEC on June 8, 2026 (“Amendment No. 2” and, together with the Original Form 10-K and Amendment No. 1, the “Form 10-K”). As previously disclosed in a Current Report on Form 8-K filed by the Company on June 8, 2026, the Board of Directors of the Company, after consultation with management and the Company’s independent registered public accounting firm, concluded that the Company’s previously issued consolidated financial statements as of and for the fiscal years ended December 31, 2025 (as included in the Original Form 10-K and Amendment No. 1) and December 31, 2024 should no longer be relied upon because of errors in those financial statements, which the Company restated in Amendment No. 2 in accordance with ASC Topic 250, “Accounting Changes and Error Corrections.” This Amendment No. 3 does not restate those financial statements again and does not change any previously reported total assets, total liabilities, stockholders’ equity (deficit), net income (loss), earnings per share, or any other amount presented in the face consolidated financial statements for any period; it revises the disclosures in Note 4 and Note 7 as described below in response to comments received from the staff of the SEC.
