QUANTUM CORPORATION REPORTS FISCAL THIRD QUARTER RESULTS

Highlights:

SAN JOSE, Calif., Jan. 25, 2012 – Quantum Corp. (NYSE:QTM), a proven global expert in data protection and big data management, today reported results for the third quarter of fiscal 2012 (FQ3’12), ended Dec. 31, 2011. Revenue for the quarter totaled $173 million, down 2 percent from the third quarter of fiscal 2011 (FQ3’11) primarily due to expected reductions in OEM and royalty revenue. On a sequential basis, third quarter revenue was up $8 million. In addition, FQ3’12 was the ninth consecutive quarter of year-over-year growth in branded revenue, which increased 3 percent and represented 81 percent of total non-royalty revenue. Quantum also generated record revenue of $36 million from disk system and software sales (including related maintenance), which increased 18 percent from the same quarter last year.

GAAP net income for FQ3’12 was $4 million, or 2 cents per diluted share, compared to GAAP net income of $6 million, or 3 cents per diluted share, in FQ3’11. Non-GAAP net income for the quarter was $12 million, or 5 cents per diluted share, down from $16 million, or 7 cents per diluted share, in the comparable quarter last year. The year-over-year decline in GAAP and non-GAAP net income was primarily due to lower tape-related service and media royalty revenue.

“We are pleased with the continued momentum we saw across key areas in the December quarter,” said Jon Gacek, president and CEO of Quantum. “Quantum branded revenue, which now makes up more than 80 percent of total product and service revenue, grew year-over-year for the ninth consecutive quarter. We also achieved a new high for disk and software revenue, with a strong contribution from new product sales, and generated our highest level of branded tape automation revenue in eight quarters.

“Sales of our DXi6701/02 and DXi4601 disk backup and deduplication products were particularly strong, and customers also responded very positively to our new vmPRO™ virtual data protection solutions, all of which speaks to the unique value we offer customers in protecting both physical and virtual machine data. We also saw significant traction with our new StorNext® appliances, as more customers are turning to Quantum for big data management solutions that enable them to maximize revenue and accelerate time-to-market by fully leveraging their digital assets.”

The company generated $16 million in cash from operating activities and ended the quarter with $69 million of senior debt, $135 million of convertible debt and $63 million in cash and cash equivalents.

Outlook
For the fourth quarter of fiscal 2012, Quantum expects:

“Safe Harbor” Statement under the U.S. Private Securities Litigation Reform Act of 1995: This press release contains “forward-looking” statements within the meaning of the Private Securities Litigation Reform Act of 1995. Specifically, without limitation, all of our statements under the “Outlook” section are forward-looking statements within the meaning of the Safe Harbor. All forward-looking statements in this press release are based on information available to Quantum on the date hereof. These statements involve known and unknown risks, uncertainties and other factors that may cause Quantum’s actual results to differ materially from those implied by the forward-looking statement. More detailed information about these risk factors, and additional risk factors, are set forth in Quantum’s periodic filings with the Securities and Exchange Commission, including, but not limited to, those risks and uncertainties listed in the section entitled “Item 1A. Risk Factors,” in Quantum’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on June 14, 2011 and Quantum’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on November 9, 2011. Quantum expressly disclaims any obligation to update or alter its forward-looking statements, whether as a result of new information, future events or otherwise.

Use of Non-GAAP Financial Measures

Quantum believes that the non-GAAP financial measures disclosed above provide useful and supplemental information to investors regarding its quarterly financial performance. Quantum management uses these non-GAAP financial measures internally to understand, manage, and evaluate the company’s business results and make operating decisions. For instance, Quantum management often makes decisions regarding staffing, future management priorities and how the company will direct future operating expenses on the basis of non-GAAP financial measures. In addition, compensation of our employees is based in part on the performance of our business based on non-GAAP operating income.

The non-GAAP financial measures used in this press release exclude the impact of amortization of intangibles, share-based compensation expense, senior debt amendment fees and loss on debt extinguishment for the following reasons:

Amortization of Intangible Assets
This includes acquired intangibles such as purchased technology and customer relationships in connection with prior acquisitions. These expenses are not factored into management’s evaluation of potential acquisitions or Quantum’s performance after completion of the acquisitions because they are not related to Quantum’s core operating performance. In addition, the frequency and amount of such charges can vary significantly based on the size and timing of acquisitions and the maturities of the businesses being acquired. Excluding acquisition-related charges from non-GAAP measures provides investors with a basis to compare Quantum against the performance of other companies without the variability caused by purchase accounting.

Share-Based Compensation Expense
Share-based compensation expense relates primarily to equity awards such as stock options and restricted stock units. Share-based compensation is a non-cash expense that varies in amount from period to period and is dependent on market forces that are often beyond Quantum’s control. As a result, management excludes this item from Quantum’s internal operating forecasts and models. Management believes that non-GAAP measures adjusted for share-based compensation provide investors with a basis to measure Quantum’s core performance against the performance of other companies without the variability created by share-based compensation as a result of the variety of equity awards used by other companies and the varying methodologies and assumptions used.

Senior Debt Amendment Fees
The senior debt amendment fees relate to a specific amendment fee and are not part of Quantum’s future core operations.

Loss on Debt Extinguishment
The loss on extinguishment of debt relates to a specific debt refinancing action and is not part of Quantum’s future core operations.

Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. They are limited in value because they exclude charges that have a material impact on the company’s reported financial results and, therefore, should not be relied upon as the sole financial measures to evaluate the company. The non-GAAP financial measures are meant to supplement, and be viewed in conjunction with, GAAP financial measures. Investors are encouraged to review the reconciliation of the non-GAAP financial measures to their most directly comparable GAAP financial measures as provided in the tables accompanying this press release.
