Quantum SEC Filings

Quantum Corporation filed a current report to let investors know it has released preliminary financial results for its fiscal second quarter ended September 30, 2025. The company furnished these early results through a press release dated October 28, 2025, which is attached as Exhibit 99.1. The information is presented under a results of operations and financial condition item and is being treated as furnished rather than filed under securities law, meaning it is not automatically incorporated into other registration statements unless specifically referenced.

Quantum Corporation (QMCO) filed a preliminary proxy for its 2025 annual meeting seeking shareholder approval for several proposals tied to a balance sheet restructuring and governance items. The centerpiece asks shareholders to approve the issuance of common stock related to a debt exchange in which approximately $52 million of term loans held by Dialectic would be exchanged for senior secured convertible notes maturing three years after closing, bearing 10% PIK interest and initially convertible at $10.00 per share, subject to quarterly resets with a $4.00 floor.

The company notes that, at a $10.00 conversion price and without additional notes, shares issuable upon full conversion would equal about 29.4% of outstanding shares post‑conversion. Quantum also seeks approval for potential issuances under anti‑dilution protections tied to a Dialectic warrant for 2,653,308 shares at $8.81, originally sized at 19.9% of outstanding. Depending on resets, excess warrant shares and any additional convertible notes, Dialectic could exceed 50% ownership upon full exercise and conversion. The proxy also proposes increasing the 2023 Long‑Term Incentive Plan reserve by 1,400,000 shares and removing individual award limits, a non‑binding say‑on‑pay, auditor ratification, and director elections. The Board emphasizes Nasdaq Rule 5635 compliance and states the debt exchange is critical to long‑term viability.

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.

Hugues Meyrath, who serves as President & CEO and a director of Quantum Corp (QMCO), reported a transaction dated 10/02/2025. The filing shows 2,975 shares of common stock were sold (transaction code S) to cover tax withholding on restricted stock units that vested from a grant dated 10/01/2024. The report gives a weighted average sale price of $10.86 (execution prices ranged from $10.85 to $10.87) and states 24,700 shares remain beneficially owned after the sale. The transaction was executed as part of block trades on 10/02/2025, and the Form 4 was signed by an attorney-in-fact on 10/03/2025.

Laura A. Nash, Chief Accounting Officer of Quantum Corp (QMCO), reported transactions on Form 4 showing equity vesting and automatic share sales to cover taxes. On 10/01/2025 Ms. Nash received 500 shares (performance‑based stock units) at a purchase price of $0 upon vesting. On the same date she sold 118 shares at a weighted average price of $9.91, and on 10/02/2025 she sold 611 shares at a weighted average price of $10.86. The filings state the October 1 sales and October 2 sales were block trades executed for multiple holders and that the share disposals were automatic, non‑discretionary sales to cover tax withholding for vested awards. Beneficial ownership reported changed from 11,868 shares after the acquisition to 11,139 shares following the October 2 sale.

Quantum Corporation filed an Amendment No. 1 to its quarterly report for the quarter ended June 30, 2025. The amendment is narrow in scope and primarily updates the list of exhibits attached to the original filing.

The company added three key exhibits that had been omitted: a Thirteenth Amendment and a Fourteenth Amendment to its Term Loan Credit and Security Agreement, and an Agency Resignation, Appointment and Assumption Agreement. It also filed updated certifications from its principal executive officer and principal financial officer under Section 302 of the Sarbanes-Oxley Act. No financial statements or other disclosures from the original quarterly report were changed.

Quantum Corporation announced a set of financing and amendment transactions with Dialectic Technology SPV LLC that convert existing term loan obligations into newly issued senior secured convertible notes and attach a warrant and registration rights. The company will exchange outstanding Term Loans (originating under the Term Loan Credit Agreement dated August 5, 2021) on a dollar-for-dollar basis for Convertible Notes governed by an indenture and will enter a Registration Rights Agreement granting demand and piggyback registration rights for common stock issuable on conversion. A Forbearance Warrant dated September 23, 2025 was issued with an exercise window out to its seventh anniversary and exercise mechanics tied to the 7-day VWAP as of the trading day ending September 22, 2025. Several related documents and amendments were filed or referenced, including a Fifteenth Amendment to the Term Loan Credit Agreement and Forms 3/4 filings by officers.
