“Our strong first quarter results reflect the adjustments in our business model and other strategic actions we’ve taken over the past five quarters to drive shareholder value by generating increased profit and cash flow while positioning the company to deliver overall revenue growth,” said Jon Gacek, president and CEO of Quantum. “These results also demonstrate the market traction we’re seeing from our continued focus on technology and product innovation. We had strong revenue momentum at quarter end, particularly related to our scale-out storage solutions and DXi appliances, and this momentum has carried over into the current quarter.

“To cite just one example, late last month we closed a scale-out storage deal for more than $3 million at a leading consumer electronics company with one of the most recognizable brands in the world. The customer purchased a full suite of Quantum StorNext and Lattus™ products that will be deployed for managing video workflows.”

“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, our statements regarding revenue recognition in the current quarter, all of our statements under the “Fiscal Second Quarter 2015 Outlook” section and the general availability launch of DXi6900 in the current quarter 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 6, 2014. 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, restructuring charges, outsourcing transition costs, proxy contest and related costs and Crossroads patent litigation costs 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.

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.

Outsourcing Transition Costs
Outsourcing transition costs are expenses attributable to transitioning our manufacturing to an outsourced model. These costs are excluded from non-GAAP financial measures because they are not considered core operating activities, and management believes that it is appropriate to exclude these costs in order to provide investors the ability to compare Quantum’s period-over-period operating results from continuing operations.

Proxy Contest and Related Costs
Proxy contest and related costs are expenses incurred to respond to activities and inquiries of Starboard Value LP, including their proxy solicitation. The Company has not incurred such expenses in historical periods and these costs are not considered core operating activities. These costs are excluded from internal operating forecasts and models. Management believes that it is appropriate to exclude these costs in order to provide investors the ability to compare Quantum’s period-over-period operating results from continuing operations.

-more-



Crossroads Patent Litigation Costs
Crossroads patent litigation costs are expenses incurred to defend ourselves and perform other activities related to a patent infringement lawsuit filed by Crossroads Systems, Inc. These costs are excluded from non-GAAP financial measures because they are not considered core operating activities, and management believes that it is appropriate to exclude these costs in order to provide investors the ability to compare Quantum’s period-over-period operating results from continuing 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.

Note 1

In the fourth quarter of fiscal year 2014, Quantum identified errors related to the accounting for rent expense and certain allowances for estimated future price adjustments to customers which impacted prior reporting periods. As a result, the company’s financial statements for the first quarter of fiscal 2014 have been revised. Revenue for the first quarter of fiscal 2014 has been reduced $0.1 million and general and administrative expense has been reduced by less than $0.1 million. For additional information, refer to our Form 10-K filed with the Securities and Exchange Commission on June 6, 2014.
