QUANTUM CORPORATION REPORTS FISCAL THIRD QUARTER RESULTS

Highlights:

SAN JOSE, Calif., Jan. 30, 2013 – Quantum Corp. (NYSE:QTM), a proven global expert in data protection and big data management, today reported results for the third quarter of fiscal 2013 (FQ3’13), ended Dec. 31, 2012. Revenue for the quarter totaled $159 million, down 8 percent from the third quarter of fiscal 2012 (FQ3’12), primarily due to expected declines in OEM and branded tape automation revenue. However, total revenue was up $12 million, or 8 percent, over the prior quarter (FQ2’13). Quantum reported revenue of $41 million from disk system and software sales (including related service), a 13 percent increase over FQ3’12 due to record revenue from DXi® disk system sales. The company also grew tape automation revenue by 25 percent over the prior quarter, as both midrange and enterprise sales rebounded strongly.

Quantum reported a GAAP net loss of $8 million, or 4 cents per share, for FQ3’13, compared to GAAP net income of $4 million in the same quarter of last year. On a non-GAAP basis, the company had net income of $5 million, or 2 cents per share, down from net income of $12 million a year earlier. The year-over-year declines were largely driven by the lower overall revenue. Compared to the prior quarter’s results, the GAAP net loss in FQ3’13 was $4 million smaller, and the non-GAAP net income was $10 million higher.

“We improved our financial performance in the December quarter, growing revenue sequentially, driving better-than-expected non-GAAP profits and generating cash,” said Jon Gacek, president and CEO of Quantum. “We also had another quarter of record DXi deduplication sales, which contributed to the 14 percent year-over-year increase in combined DXi and StorNext® revenue we’ve achieved over the first three quarters of the fiscal year.

“In addition, even as we scaled back spending, we continued to invest in new, industry-leading products and solutions for protecting and managing digital content in physical, virtual, cloud and big data environments. These include our Lattus™ wide area storage systems, vmPRO 3.0 virtual backup software, DXi6800 deduplication appliances and Scalar i6000 HD enterprise tape libraries.”

Quantum generated $6 million in cash from operating activities in FQ3’13 and ended the quarter with $55 million in cash and cash equivalents.

For the fourth quarter of fiscal 2013, 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 “Risk Factors” in Quantum’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on June 14, 2012 and in Quantum's Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on November 9, 2012. 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 acquisition expenses, amortization of intangibles, 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.

-more-



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.

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.
