Quantum Corporation disclosed that on August 21, 2025 it received a notice from the Nasdaq Listing Qualifications staff stating the company is not in compliance with Nasdaq Listing Rule 5250(c)(1) because it did not timely file its Quarterly Report for the fiscal quarter ended June 30, 2025. The company previously filed a Form 12b-25 on August 15, 2025 saying the delay stems from additional time needed to finalize financial statements and for its independent auditors to complete their review, including annual and quarterly periods in the Annual Report for the year ended March 31, 2025. Quantum says it is working to complete the review and file the Quarterly Report within Nasdaq's prescribed timeline. The Nasdaq notice does not have an immediate effect on the listing; the stock will continue to trade while the company addresses the filing requirement.
Quantum Corporation (QMCO) reports material financial and operational challenges. The company describes its product portfolio across primary and secondary storage, services, and tape media, and states it operates as a single reporting segment. Management disclosed restatements of prior financial statements and identified material weaknesses in internal controls. Quantum expressed substantial doubt about its ability to continue as a going concern, expects a covenant violation on its Term Loan as of September 30, 2025, and has classified that Term Loan as a current liability. The company received a Nasdaq notice for late filings and faces potential delisting. It disclosed significant indebtedness, multiple loan amendments and warrants issued to lenders, and non-cancelable inventory commitments of $48.6 million.
Quantum Corporation (QMCO) reported the resignation of its Chief Financial Officer, Lewis W. Moorehead, effective August 18, 2025, and appointed Chief Accounting Officer Laura A. Nash as Principal Financial Officer effective the same date. The company said there is no indication of fraud or intentional misconduct affecting its financial statements and has begun a search for a permanent CFO. The filing also updates a previously announced restatement for the quarter ended December 31, 2024: the company expects the restatement to reduce revenue by approximately $3.9 million and produce a similar decrease in net loss from operations for the identified period. The review is ongoing and timing for filing the restatement has not been specified.
Quantum Corporation filed a Form 12b-25 to notify that it will not meet the original due date for its Quarterly Report on Form 10-Q for the quarter ended June 30, 2025. The company says it cannot file by August 14, 2025 without unreasonable effort or expense because it needs additional time to finalize its financial statements and for its independent auditor to complete their review, including financial statements in the Annual Report on Form 10-K for the year ended March 31, 2025.
The company highlights uncertainties around its ongoing review procedures, including accounting related to revenue contracts and application of standalone selling price, and notes that these processes could uncover additional information or lead to changes in assumptions. It also cites risks related to legal proceedings and investigations, stock exchange continued listing standards, and its ability to maintain effective internal control over financial reporting.
Quantum Corporation concluded that its previously issued unaudited interim condensed consolidated financial statements for the fiscal third quarter ended December 31, 2024 are no longer reliable and will be restated. Management identified inconsistencies in service and subscription revenue accounted for under Topic 606 and updated the periods over which revenue is recognized and the standalone selling prices for the fiscal year ended March 31, 2025. The company currently expects the Restatement will decrease revenue and similarly decrease net loss from operations by approximately $3.9 million for the Non-Reliance Period. The Audit Committee determined there were material weaknesses in internal control over financial reporting and disclosure controls related to revenue recognition as of December 31, 2024 and March 31, 2025. Adjustments to other quarters were not material and will be revised in comparative period information. The Audit Committee discussed these matters with Grant Thornton LLP.
