Quantum SEC Filings

Quantum Corporation (QMCO) set December 16, 2025 as the date for its 2025 annual meeting of stockholders. The company outlined the window for stockholder proposals not included in the proxy materials under its Amended and Restated Bylaws, noting that the meeting date is more than 60 days after the prior year’s anniversary, which changes the normal timing rules.

For this meeting, written notice to the Secretary at the company’s principal executive offices must be received by the close of business on October 30, 2025. Proposals and director nominations also must comply with SEC Rules 14a-8 and 14a-19, Delaware law, and the company’s Bylaws.

Dialectic Technology SPV LLC and related parties disclosed a financing amendment with Quantum Corp (QMCO) that grants Dialectic a Forbearance Warrant to buy 2,653,308 shares (reported as 16.6% of outstanding stock) at an initial exercise price of $8.81, exercisable for seven years. The warrant and a registration‑rights agreement were issued as consideration for forbearances and amendments to term loan agreements covering approximately $51.3M of loans.

Concurrently, the parties agreed a Transaction Agreement providing for a potential Debt Exchange where outstanding term loans owed to Dialectic could be converted into senior secured convertible notes with a 10% PIK interest rate, a contemplated initial conversion price of $10.00 per share and a three‑year maturity; at that price conversion would represent roughly 29.4% of the issued and outstanding stock as of the agreement date. The Transaction Agreement includes liquidity covenants requiring minimum cash balances rising from $3.75M in Q1 2026 to $7.5M by Q4 2026 and contains customary closing conditions including stockholder approval of the Debt Exchange.

Quantum Corporation disclosed that its prior auditor, Grant Thornton, issued audit reports for the fiscal years ended March 31, 2025 and March 31, 2024 without an adverse or qualified opinion but included an explanatory paragraph about the company’s ability to continue as a going concern. Grant Thornton reported no disagreements with management but noted material weaknesses in the company’s internal control over financial reporting related to the controls environment, revenue recognition, manufacturing inventory, and warrants agreements, as described in Item 9A.

The Audit Committee completed a competitive selection and, on September 30, 2025, chose CohnReznick LLP to serve as the independent registered public accounting firm for the fiscal year ending March 31, 2026, contingent on completion of standard client acceptance procedures. Grant Thornton provided a letter dated October 6, 2025 and the company authorized Grant Thornton to respond fully to successor-auditor inquiries about the disclosed reportable events.
