Amendment Description This Amendment No. 1 on Form 10-K/A (this “Amendment”) amends the Annual Report on Form 10-K of Flux Power Holdings, Inc. for the year ended June 30, 2025, originally filed with the U.S. Securities and Exchange Commission (“SEC”) on September 17, 2025 (the “Original Filing”). We are filing this Amendment to amend Part III of the Original Filing to include the information required by and not included in Part III of the Original Filing because we did not file our definitive proxy statement within 120 days of the end of our fiscal year ended June 30, 2025. In connection with the filing of this Amendment and pursuant to the rules of the SEC, we are including with this Amendment new certifications of our principal executive officer and principal financial officer pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. Accordingly, Item 15 of Part IV and the Exhibit Index has also been amended to reflect the filing of these new certifications. Because no financial statements have been included in this Amendment, we are not including new certifications pursuant to Section 906 of the Sarbanes-Oxley Act of 2002.   The reference on the cover page of the Original Filing to the incorporation by reference of our definitive proxy statement into Part III of the Original Filing is hereby deleted.   Except for the Cover Page, Part III, Part IV, Item 15 and the Exhibit Index, no other changes are made to the Original Filing. The Original Filing continues to speak as of the date of the Original Filing. Unless expressly stated, this Amendment does not reflect events occurring after the filing of the Original Filing, nor does it modify or update in any way the disclosures contained in the Original Filing. Accordingly, this Amendment should be read in conjunction with the Original Filing and our other filings with the SEC.   Unless the context otherwise requires, the “Company,” “Flux,” “we,” “us,” and “our” refer to the combined business of Flux Power Holdings, Inc., a Nevada corporation and its wholly owned subsidiary, Flux Power, Inc., a California corporation (“Flux Power”).
