Annual Shareholder Meeting Proxy Statement 2025

A Message from Our Leadership

The question I’ve heard most in the last few months is, “Why would you want to come out of retirement to go back to work at Quantum?” The honest answer is that it feels like fate.

Much of my professional work has been in the storage industry. More specifically, I have been associated with Quantum since the 1990s, as a supplier, employee, competitor, or Board member. Each of these roles has given me the ability to learn, experience, and understand Quantum’s products and opportunities in a unique way. This tenure makes it feel like Quantum is in my blood.

I am extremely happy to step into the President and Chief Executive Officer role, and am passionately focused on driving the company toward successfully achieving the opportunities ahead of us. We have fantastic products, amazing people, and fascinating customers. I’m looking forward to combining all of those resources into providing unmatched solutions for unstructured data and AI-enabled workflows.

I sincerely believe Quantum is uniquely positioned to grow our business and deliver more consistent results for our shareholders. We believe that your support on the proposals included in this proxy statement will help us do that.

Hugues Meyrath

President and Chief Executive Officer

Fiscal year 2025 created the foundation for significant change for Quantum. We revised our product portfolio, go to market strategies and resources, customer purchase methodologies, access to capital, and global employee footprint.

On the heels of those actions, we ushered in fiscal year 2026 by revising our debt structure and reconstituting our executive management team. Having known Hugues for more than 20 years, I could not have been more pleased to welcome him as Quantum’s new President and Chief Executive Officer. His depth and breadth of interaction with Quantum over the last thirty years is rare and sincere, and he was truly excited to have the opportunity to lead the company forward.

I have no doubt that excitement has translated into renewed focus and engagement with Quantum’s leadership team, employees, customers, suppliers, and other partners. Quantum’s recent history has been defined by charting a new direction; fiscal year 2026 presents an opportunity to leverage that work and define a future that can deliver positive outcomes for all stakeholders. We recommend you support our proxy proposals as a critical step in continuing Quantum’s transformation.

I’ve very excited to play a part in that process and support Hugues and the Quantum team through this journey.

Don Jaworski

Chairman of the Board

Board Meetings and Independence

Board Meeting Attendance

The Board met a total of 34 times in Fiscal 2025. All Board members during Fiscal 2025, other than Ms. White, attended at least 75% of the Board and Committee meetings for which they were eligible to attend, which is the expectation outlined in our Corporate Governance Principles. Ms. White’s ability to join at least 75% of the meetings she was eligible to attend was atypically impacted by the unusually high number of meetings, her job change, and significant work-related international travel. The Board anticipates that Ms. White will have increased ability to attend meetings in the fiscal year ending March 31, 2026 (Fiscal 2026), as she had in prior years. Each of the directors nominated for election at our 2024 annual meeting of shareholders, other than
Mr. Neumeyer and Ms. White, who had unavoidable business conflicts, attended that meeting.

Director Independence

The Board has determined that all current members other than Mr. Meyrath are independent directors as defined under the rules of the Nasdaq Stock Market LLC (Nasdaq).

We also exceed Nasdaq listing standards by requiring approximately 75% of our Board to be comprised of independent directors.

Our independent directors meet in executive session, without employee directors, at least as often as each regularly scheduled quarterly Board meeting. The independent directors are also empowered to request reporting from any employee during the executive session, including audit and compliance personnel.

Leadership Structure

Quantum’s Board is committed to strong, independent Board leadership and oversight of management’s performance. The Board determines the Chair assignment, from time to time and in its business judgement after considering relevant factors, including Quantum’s needs and our shareholders’ best interests. With
Mr. Meyrath’s appointment as President and Chief Executive Officer on June 2, 2025, the Board determined it would be appropriate and strengthen the Company’s corporate governance to separate the roles of Board Chair and CEO. Following a thorough evaluation, the Board determined that Mr. Jaworski, who previously served as Lead Independent Director, should assume the role of Chairman of the Board. The Board believes this structure promotes implementing accountability for the Company’s performance.

The Chair focuses on effectively leading and managing the Board, with responsibilities described in more detail in our Corporate Governance Principles available on the investor relations section of our website at www.investors.quantum.com.

The Audit Committee of the Board of Directors (Audit Committee) met ten times in Fiscal 2025. All members are independent and financially literate. Mr. Tracy qualifies as an “audit committee financial expert” per Nasdaq and SEC requirements. The Audit Committee’s primary responsibilities are to:
