QUANTUM CORPORATION REPORTS FISCAL 2013 AND FOURTH QUARTER RESULTS

Grows Disk Systems and Software Revenue to $152 Million for the Year, Highest Level to Date and 11% Increase over Fiscal 2012

SAN JOSE, Calif., May 8, 2013 – Quantum Corp. (NYSE:QTM), a proven global expert in data protection and big data management, today reported results for fiscal 2013 (FY13) and the fourth quarter (FQ4’13), ended March 31, 2013. Revenue for the year totaled $588 million, down 10 percent from fiscal 2012 (FY12), primarily due to decreased market demand for tape products. Quantum reported record revenue of $152 million from disk systems and software sales (including related service), an 11 percent increase over FY12 driven by record revenue from both StorNext® and midrange DXi® sales. For FQ4’13, Quantum reported $140 million in revenue, a 13 percent decline from the same period last year (FQ4’12), also primarily due to lower demand for tape. Disk systems and software revenue (including related service) grew for the seventh consecutive quarter on a year-over-year basis.

Quantum reported a GAAP net loss for FY13 of $52 million, or 22 cents per diluted share, compared to $9 million in the prior year. On a non-GAAP basis, Quantum had a net loss of $14 million for the year, or 6 cents per diluted share, down from $30 million of net income in FY12. For FQ4’13, Quantum had a GAAP net loss of $15 million, or 6 cents per diluted share, compared to a net loss of $11 million in the same quarter last year. Non-GAAP net loss for FQ4’13 was $5 million, or 2 cents per diluted share, down from $1 million of net income a year earlier. The year-over-year declines were largely due to the lower tape product and royalty revenue.

“Although this was a challenging year for storage generally, and a particularly tough one for tape, we grew our disk systems and software revenue to a new high, maintained our market share leadership in tape, introduced a broad range of innovative new products and further improved our balance sheet,” said Jon Gacek, president and CEO of Quantum. “We will build on this progress in the new fiscal year to drive a balance of growth and profit, and, we are well-positioned to do so.

“Our product portfolio is a key strength, and we will continue to be aggressive about utilizing our technology assets to create products and solutions that are clearly differentiated and deliver superior value to customers in both data protection and big data management. This will include new deduplication, virtualization, cloud, workflow and archive offerings.”

Quantum generated $16 million in cash from operations in FQ4’13 and ended FY13 with $72 million in total cash and cash equivalents.

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 acquisition expenses, amortization of intangibles, loss on debt extinguishment, restructuring charges and share-based compensation expense for the following reasons:

Acquisition Expenses
The acquisition expenses were those expenses incurred to acquire Pancetera, Inc. and are not part of Quantum’s future core operations.

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.

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

Restructuring Charges
Restructuring charges primarily relate to expenses associated with changes to Quantum’s operating structure. Restructuring charges are excluded from non-GAAP financial measures because they are not considered core operating activities. Although Quantum has engaged in various restructuring activities in the past, each has been a discrete event based on a unique set of business objectives. Management believes that it is appropriate to exclude restructuring charges from Quantum’s non-GAAP financial measures, as it enhances the ability of investors to compare Quantum’s period-over-period operating results from continuing operations.

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.

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.
