•

Allows up to an additional $15 million of SEPA proceeds to be retained by the Company for working capital and general corporate purposes

 

•

Eliminates existing leverage and minimum liquidity covenants

 

•

Issued Dialectic a warrant to purchase 2,653,308 shares of the Company’s common stock as consideration

“This transaction to restructure a substantial portion of the Company’s outstanding term debt represents a significant step toward our goal of becoming debt-free,” stated Hugues Meyrath, CEO of Quantum. “The proposed exchange of term debt for convertible notes demonstrates Dialectic’s belief in the Company’s strategic vision and long-term growth opportunities, while also aligning Dialectic as a future strategic partner. In addition, we believe this transaction provides increased financial flexibility to execute on our operating initiatives and revitalized go-to-market strategy.”

Meyrath continued, “This important milestone in our financial transformation follows the recent rebuilding of our Board of Directors and executive team, including leadership changes throughout the organization. We believe the increased financial flexibility provided by this transaction allows us to focus on our goal of delivering profitable performance and revenue growth.”

“This transaction is an important milestone in Quantum’s ongoing operational and financial transformation,” stated John Fichthorn, Managing Partner of Dialectic Capital Management, investment advisor to Dialectic. “At Dialectic, we are committed to supporting the management in building a focused, profitable, and growing storage technology company with a clear strategy and strong alignment across all stakeholders. By restructuring the balance sheet and positioning Quantum for growth, our goal is to align the interests of management, employees, and shareholders through the performance of the equity.”
