Item 1.01 Entry into a Material Definitive Agreement.

As previously disclosed, on September 23, 2025, Quantum Corporation, a Delaware corporation (the “Company”), entered into a Transaction Agreement (the “Transaction Agreement”) with Dialectic Technology SPV LLC, a Delaware limited liability company (“Dialectic”), OC III LVS XXXIII LP, a Delaware limited partnership (“LVS XXXIII”), and OC III LVS XL LP, a Delaware limited partnership (“LVS XL” and together with LVS XXXIII, the “OC III Lenders”, and the OC III Lenders together with Dialectic, collectively the “Lenders” and each a “Lender”). On December 18, 2025, the Company closed the transactions contemplated by the Transaction Agreement (the “Closing”), including its issuance to Dialectic, on a dollar-for-dollar basis, senior secured convertible notes in an aggregate principal amount of $54,718,114 (the “Convertible Notes”) in exchange (the “Debt Exchange”) for the amounts then outstanding and owing by the Company to Dialectic under certain term loans held by Dialectic (including principal, any prepayment penalties and exit fees, but excluding any accrued and unpaid interest thereon, the “Term Loans”). The Closing was conditioned upon, among other things, approval of the Debt Exchange by the Company’s shareholders, which approval was obtained on December 16, 2025.
Convertible Notes and Indenture

The Convertible Notes were issued to Dialectic pursuant to that certain indenture, dated December 18, 2025 (the “Indenture”), among the Company, the guarantors party thereto and U.S. Bank Trust Company, National Association, as trustee and collateral agent. The Convertible Notes mature December 18, 2028 (the “Maturity Date”) and have an interest rate of 10.00% per annum, payable in kind, compounded annually. The initial conversion price of the Convertible Notes equals $10.00 per share (the “Conversion Price”) of the Company’s common stock, $0.01 par value per share (“Common Stock”), subject to adjustment for stock splits and similar events, and includes antidilution protections in favor of Dialectic as described in the Indenture. The Conversion Price is subject to adjustment on the last day of the three calendar quarters immediately following the Closing (each, a “Reset Price Date”) to the greater of (a) $4.00 per share and (b) the lesser of (i) the then Conversion Price and (ii) the 30-day Daily VWAP (as defined in the Indenture) of the Common Stock immediately preceding the Reset Price Date.

Immediately after the Closing, the shares issuable to Dialectic upon (i) the full conversion of the Convertible Notes outstanding at the time of the Closing at a Conversion Price of $10.00 (without taking into account any interest payable on the Convertible Notes following the Closing) and (ii) the full, cash exercise of Dialectic’s forbearance warrant dated September 23, 2025, with no adjustment to the exercise price, would represent approximately 36.9% of the Company’s issued and outstanding Common Stock immediately after giving effect to such conversion and exercise.

At the Company’s option, all outstanding principal amount, accrued and unpaid interest and premium, if any, of any Convertible Notes outstanding on the Maturity Date shall be exchanged into shares of Common Stock at an exchange price equal to 80% of the Market Price, defined as the average of the Daily VWAP for each of the five lowest consecutive trading days during the 20 consecutive trading days ending on (and including) the trading day immediately prior to the Maturity Date. Following the six-month anniversary of Closing, if certain conditions are met, the Company may elect to require the exchange of a portion of the total outstanding amount of any Convertible Notes into shares of Common Stock at the then outstanding Conversion Price.

The Indenture contains certain affirmative and negative covenants substantially consistent with the Fifteenth Amendment to Term Loan Credit and Security Agreement, dated September 30, 2025, by and among the Company, Quantum LTO Holdings, LLC, the borrowers and guarantors party thereto, the lenders party thereto, and Alter Domus (US) LLC, as disbursing agent and collateral agent (the “Fifteenth Term Loan Amendment”), as well as a covenant requiring the Company to maintain minimum liquidity of $3.75 million as of the last day of the first quarter of 2026, $5.0 million as of the last day of the second quarter of 2026, $6.25 million as of the last day of the third quarter of 2026 and $7.5 million as of the last day of the fourth quarter of 2026 and each quarter thereafter. The Convertible Notes are secured by all of the Company’s assets which secure the Term Loans.

In addition, at the Closing, the Company and Dialectic entered into a registration rights agreement (the “Registration Rights Agreement”) pursuant to which, among other things, the Company will provide Dialectic (or any assignee of the Convertible Notes) with certain demand and piggyback registration rights with respect to the shares of Common Stock issuable upon any conversion of the Convertible Notes.

The foregoing descriptions are qualified in their entirety by reference to the full text of the Indenture (including the form of Convertible Notes contained therein) and the Registration Rights Agreement, copies of which are filed as Exhibits 4.1 and 4.2, respectively, to this Current Report on Form 8-K and are incorporated herein by reference. Additionally, the foregoing descriptions of the Transaction Agreement and the Fifteenth Term Loan Amendment are qualified in their entirety by reference to the full text of the Transaction Agreement and the Fifteenth Term Loan Amendment, copies of which were filed as Exhibits 10.1 and 10.2 to the Company’s Current Report on Form 8-K filed with the SEC on September 23, 2025 and are incorporated herein by reference.
