It discloses 14,134,629 shares outstanding as of December 31, 2025 and describes the Convertible Notes (aggregate principal $54,718,114, initial conversion price $10.00, subject to quarterly resets with a $4.00 floor and other customary terms and registration rights).
Quantum Corporation is registering up to 18,207,453 shares of common stock for potential resale by Dialectic Technology SPV LLC, the holder of Quantum’s 10.00% PIK Senior Secured Convertible Notes due 2028. These shares may be issued upon conversion of the notes.
The notes have an aggregate principal amount of $54,718,114, an initial conversion price of $10.00 per share with reset features down to a floor of $4.00, and mature three years after closing. Quantum will not receive any proceeds from sales of these shares by the selling stockholder.
Quantum had 14,134,629 shares outstanding as of December 31, 2025. The company notes that resale of these shares, or the perception that such sales could occur, could put downward pressure on its stock price, and highlights liquidity covenants and asset security supporting the convertible notes.
Quantum Corporation reported a quarterly net loss of $27.8 million on revenue of $74.6 million for the quarter ended December 31, 2025, with revenue up modestly from the prior-year period but still below year-to-date 2024 levels. Gross margin was 38.8%, as higher-margin secondary storage and media sales offset weaker service and royalty revenue. Cash and cash equivalents were $13.2 million, while net cash used in operating activities was $37.4 million over nine months, underscoring liquidity pressure. The balance sheet shows a stockholders’ deficit of $184.2 million, a Term Loan of $54.6 million, and a fair-value Convertible Note of $75.9 million. Management discloses substantial doubt about the company’s ability to continue as a going concern, noting the Term Loan maturing on August 5 2026 cannot be repaid from existing or expected operating cash and may require additional financing under a Standby Equity Purchase Agreement, from which about 8.2 million shares have already been sold for roughly $89.6 million.
Quantum Corporation reported improved fiscal Q3 2026 results with a smaller adjusted loss and stronger top-line performance. Revenue was $74.6 million, above preliminary results of $72.7 million and original guidance of $67 million plus or minus $2 million, driven by strong quarter-end shipments and conservative deferred revenue assumptions.
GAAP net loss was $27.8 million, or $2.03 per share, largely impacted by a $28.9 million loss on debt extinguishment, while non-GAAP adjusted net loss narrowed to $4.9 million, or $0.36 per share. Non-GAAP adjusted EBITDA improved to a positive $2.9 million from $0.5 million in the prior quarter. Term loan debt fell to $54.6 million from $105.9 million a year earlier, with a new convertible note fair valued at $75.9 million.
For fiscal Q4 2026, Quantum guides to revenue of $68 million plus or minus $2 million, non-GAAP adjusted operating expenses of $27 million plus or minus $2 million, non-GAAP adjusted basic net loss per share of $0.33 plus or minus $0.10, and non-GAAP adjusted EBITDA around breakeven.
Quantum Corporation’s new Chief Financial Officer, William Hillis White, filed an initial ownership report on Form 3 for the company’s common stock. The filing states that no securities are beneficially owned, meaning he reports holding no Quantum shares or derivatives as of the stated event date.
