Amendment Description	This Amendment No. 2 (this “Amendment No. 2”) to the Annual Report on Form 10-K of FiEE, Inc. (the “Company”) for the year ended December 31, 2024, amends the Company’s Form 10-K for the fiscal year ended December 31, 2024, originally filed with the U.S. Securities and Exchange Commission (“SEC”) on April 10, 2025 (as amended on April 30, 2025, the “Original Filing”). The Company is filing this Amendment No. 2 to address management’s re-evaluation of disclosure controls and procedures and to reflect the identification of a material weakness in the Company’s disclosure controls and procedures and internal control over financial reporting. The material weakness did not result in any change to the Company’s consolidated financial statements as set forth in the Original Filing. This Amendment No. 2 is limited in scope to make the following changes: ●To amend Part II, Item 9A. Controls and Procedures to reflect management’s conclusion that the Company’s disclosure controls and procedures were not effective as of December 31, 2024, due to a material weakness in the Company’s internal control over financial reporting identified subsequent to the date of the Original Filing. ●To amend Part IV, Item 15. Exhibits and Financial Statement Schedules to include currently dated certifications from the Company’s principal executive officer and principal financial officer required under Sections 302 and 906 of the Sarbanes-Oxley Act of 2002, which have been executed and are filed herewith as Exhibits 31.1, 31.2, 32.1 and 32.1 to this Amendment No. 2. Except as described above, no other changes are being made to the Original Filing. Further, except as expressly stated, this Amendment No. 2 does not reflect events occurring after the filing of the Original Filing or modify or update in any way any of the other items or disclosures contained in the Original Filing, including, without limitation, the Company’s consolidated financial statements. Accordingly, this Amendment No. 2 should be read in conjunction with the Original Filing and the Company’s other filings with the SEC subsequent to the filing of the Original Filing.
