The company exchanged term loans for $54,718,114 of senior secured convertible notes bearing 10.00% pay-in-kind interest and maturing on December 18, 2028. The initial conversion price is $10.00 per share, with reset features that can adjust it down to no lower than $4.00 based on trading prices after closing.
If the notes were fully converted at $10.00 and Dialectic fully exercised its existing forbearance warrant, Dialectic would hold about 36.9% of Quantum’s common stock.

Shareholders approved the convertible note exchanges, potential additional Dialectic funding, anti-dilution-related warrant issuances, a 1,400,000-share increase to the 2023 Long-Term Incentive Plan, executive compensation on an advisory basis, and the appointment of CohnReznick LLP as auditor.
