SAN JOSE, Calif., April 4, 2011 - Quantum Corp. (NYSE:QTM), the leading global specialist in backup, recovery and archive, today announced that Jon Gacek has been appointed CEO, succeeding Rick Belluzzo, who has led the company since September 2002. The leadership transition, which is effective immediately, is the result of a planned management succession begun last year. Gacek has also been appointed to Quantum's Board of Directors.

Gacek has been president and COO of Quantum since January of this year and had previously served as executive vice president, COO and CFO since May 2009. He joined Quantum as executive vice president and CFO in August 2006, upon Quantum's acquisition of Advanced Digital Information Corp. (ADIC). Before that, Gacek served as CFO at ADIC for seven years and as an audit partner at PricewaterhouseCoopers LLP, where he led the Technology Practice in the firm's Seattle office.

Belluzzo will continue as chairman of Quantum's Board of Directors and also assume the newly created position of executive chairman. In this role, he will assist in the leadership transition, primarily engaging with key customers and partners, as needed.

"During my time as CEO, and particularly since the merger with ADIC, we have been focused on moving Quantum to a position of delivering consistent profitability, with a strong foundation for future growth," said Belluzzo. "Over the past year, we have largely completed this transition, as evidenced by gross margins consistently above 40 percent, improved profitability, and significant revenue growth in disk systems and software, where we have established ourselves as a key player in high opportunity market segments. Jon has played an instrumental role in this success and has clearly demonstrated the ability to lead Quantum moving forward."

"I am very excited to be taking on this new role and building on the work we've done," said Gacek. "Quantum is well-positioned as we begin the new fiscal year, with expanded market opportunities, increased channel momentum and new product platforms and enhancements across our portfolio. These include our new DXi 2.0 backup, deduplication and replication software, which recently began shipping and enables us to deliver both significantly higher performance and better price-performance than competitive offerings.

"I will talk more about our plans and expectations for FY12 when we announce our March quarter financial results on May 17, but we do expect to grow both total revenue and branded revenue for the year as we capitalize on the opportunities ahead," Gacek added.

Quantum said that it will hold a conference call today (details below) to discuss the CEO succession announcement further and a separate call on May 17 to talk about its full results from the fourth quarter of fiscal 2011, ended March 31, 2011 (FQ4'11). In the meantime, the company stated that it expects March quarter revenue to be approximately $165 million, with preliminary results indicating growth in total branded revenue and disk systems and software revenue over the comparable quarter last year. Quantum also reported that it had paid down $40 million of senior debt in the March quarter. Finally, the company said it has experienced minimal disruption to date from the disaster in Japan.

Quantum will hold a conference call today, April 4, 2011, at 2:00 p.m. PDT, to discuss the CEO succession announcement. Press and industry analysts are invited to attend in listen-only mode. Dial-in number: (480) 629-9725 (U.S. & International). Quantum will provide a live audio webcast of the conference call beginning today, April 4, 2011, at 2:00 p.m. PDT.
