Quantum Corporation
Form 10-Q/A
(Amendment No. 1)
For the Quarter Ended June 30, 2025

EXPLANATORY NOTE
This Amendment No. 1 on Form 10-Q/A (this “Amendment”) amends the Quarterly Report on Form 10-Q of Quantum Corporation (the “Company”) for the quarter ended June 30, 2025, originally filed with the U.S. Securities and Exchange Commission (the “SEC”) on September 11, 2025 (the “Original Filing”).
This Amendment is being filed to revise Part II “Item 6. Exhibits” to include Exhibits 10.6, 10.7 and 10.8, which were inadvertently omitted from the Original Filing.
In addition, as required by Rule 12b-15 of the Securities and Exchange Act of 1934 (the “Exchange Act”), new certifications by the Company’s principal executive officer and principal financial officer are filed herewith as Exhibits 31.3 and 31.4, respectively, to this Amendment under Item 6, pursuant to Rule 13a-14(a) or 15d-14(a) of the Exchange Act. Because no financial statements have been included in this Amendment and this Amendment does not contain or amend any disclosure with respect to Items 307 and 308 of Regulation S-K, paragraphs 3, 4 and 5 of the certifications have been omitted. The Company is also not including new certifications under Section 1350 of Chapter 63 of Title 18 of the United States Code (18 U.S.C. 1350) (Section 906 of the Sarbanes-Oxley Act of 2002), as no financial statements are being filed with this Amendment.
Other than as expressly set forth herein, this Amendment does not, and does not purport to, amend, update or restate the information in the Original Filing or reflect any events that have occurred after the Original Filing was made. Information not affected by this Amendment remains unchanged and reflects the disclosures made at the time as of which the Original Filing was made. This Amendment should be read together with the Original Filing and the Company’s other filings with the SEC.



ITEM 6. EXHIBITS

The exhibits required to be filed or furnished as part of this Quarterly Report are listed below. Notwithstanding any language to the contrary, exhibits 32.1 and 32.2 shall not be deemed to be filed as part of the Original Filing or this Amendment for purposes of Section 18 of the Exchange Act or deemed to be incorporated by reference into any filing under the Exchange Act or the Securities Act of 1933, except to the extent that the Company specifically incorporates it by reference.

Frequently asked questions

When did Quantum Corp file this 10-Q/A?
Quantum Corp (QMCO) filed this Amended Quarterly Report (Form 10-Q/A) with the SEC on September 23, 2025. The accession number assigned by EDGAR is 0000709283-25-000058.
What does a 10-Q/A disclose?
Form 10-Q is the SEC's quarterly report. Public companies file it after each of the first three fiscal quarters to disclose unaudited financial statements and management's discussion of operations. The fourth-quarter results are rolled into the annual 10-K instead.
How is a 10-Q different from a 10-K?
Form 10-Q is filed three times a year (after Q1, Q2, and Q3 — the fourth quarter rolls into the 10-K). 10-Qs contain unaudited interim financial statements and a shorter MD&A. They're due 40 or 45 days after quarter end depending on filer size.
Where can I find Quantum Corp's prior quarterly reports on EDGAR?
The SEC EDGAR browser lists every 10-Q/A Quantum Corp has filed under CIK 709283, sortable by date. Use the "View on SEC EDGAR" link in the page header, or browse directly via https://www.sec.gov/cgi-bin/browse-edgar.
