Seasoned finance executive brings growth-focused mindset to advancing Quantum’s long-term strategy

CENTENNIAL, Colo. — Feb. 2, 2026 — Quantum Corporation (Nasdaq: QMCO) today announced the appointment of William H. White as its Chief Financial Officer. White will lead Quantum’s global finance organization, including financial strategy and operations, capital structure initiatives, and investor relations, supporting the company’s next phase of growth and operational execution.

White brings more than two decades of experience transforming technology companies through disciplined financial leadership and strategic capital allocation. He is recognized for improving operational rigor and modernizing reporting and forecasting processes.

“Will brings an exceptional combination of financial discipline, operational leadership, and strategic vision to help drive Quantum’s execution at this stage of our journey,” said Hugues Meyrath, President and Chief Executive Officer of Quantum. “He has a proven ability to strengthen fundamentals while enabling growth, with invaluable experience scaling technology businesses. I look forward to working with him as we continue our efforts to deliver long-term value for customers, partners, and shareholders.”

Most recently, White served as CFO and Head of Revenue Operations at Emotive, a venture-backed SaaS company, where he led a three-year financial and operational turnaround that improved EBITDA by more than $30 million and culminated in a successful strategic exit. Earlier in his career, White was Managing Partner at Goldblum Lentz & Co., where he advised on mergers, acquisitions, and capital transactions. He has also led numerous enterprise system transformations, accelerating close cycles and improving financial transparency for executive teams and institutional investors.

“I am excited to join Quantum at such a pivotal time,” said White.“Quantum has a unique opportunity to lead in managing data across its entire lifecycle, especially as organizations are looking to retain all data to leverage AI. I look forward to working together with Hugues and the leadership team to strengthen execution, enhance financial performance, and support the company’s long-term growth strategy.”

White holds an MBA from the University of Denver and a B.A. from the University of Colorado Boulder.

As part of White’s compensation package and as an inducement material to his acceptance of employment with the company, the Leadership and Compensation Committee (Committee) of Quantum’s Board of Directors approved the grant of 25,000 restricted stock units, which will vest in three equal annual installments, and 25,000 performance-based restricted stock units, which will vest based on the achievement of performance metrics approved by the Committee. Both grants are subject to White’s continued employment and are expected to be effective March 2, 2026 under Quantum’s 2021 Inducement Plan.
