“Safe Harbor” Statement: This press release contains “forward-looking” statements. All statements other than statements of historical fact are statements that could be deemed forward-looking statements. Specifically, but without limitation, our statement that we will build on our progress through several strategic initiatives that leverage our technology, product and install base strengths and capitalize on the market trends in data protection and scale-out storage – with the goal of delivering profitable growth in our core business and increased shareholder value, and all of the statements under the Fiscal Year 2015 Outlook heading 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 statements. These risks include operational difficulties, unforeseen technical limitations, unexpected changes in market conditions and unanticipated changes in customers’ needs or requirements, as well as the risks 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 Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on February 7, 2014 and in Quantum’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on June 7, 2013. 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, restructuring charges and outsourcing transition 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 valuation methodologies and assumptions used.

-more-

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.

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

During 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. In addition, the company had previously identified errors related to the accrual for sales commissions that also impacted prior reporting periods. While these errors were not material to any previously issued annual or quarterly consolidated financial statements, management concluded that correcting the errors in fiscal 2014 would be material to the year’s consolidated financial statements. Quantum will revise its prior period annual and quarterly consolidated financial statements to correct the errors when next presented in future SEC filings.

In this earnings release, the company has revised the March 31, 2013 Condensed Consolidated Balance Sheet and the Condensed Consolidated Statements of Operations and Cash Flows for the quarter and fiscal year ended March 31, 2013 to record reduced rent expense, additional accounts receivable allowance for future price adjustments and revised sales commission expense. The net impact of the revision was to (a) increase the previously reported net loss for the quarter ended March 31, 2013 by $600,000, (b) reduce the previously reported net loss for the fiscal year ended March 31, 2013 by $200,000 and (c) increase the previously reported accumulated deficit and stockholders’ deficit at March 31, 2013 by $800,000.
