SAN JOSE, Calif. — Jan. 12, 2017 — Quantum Corp. (NYSE: QTM) today announced preliminary results for the fiscal third quarter 2017, ended Dec. 31, 2016 that were above the high end of the previously provided guidance range for both total revenue and profitability. The company currently expects:

“We’re very pleased with our continued strong performance this fiscal year,” said Jon Gacek, president and CEO of Quantum. “For the third straight quarter, we increased total revenue and profit year-over-year, with growth in both scale-out tiered storage and data protection. In addition, comparing the first nine months of fiscal 2017 to the same period a year earlier, we not only grew scale-out tiered storage 26 percent but also increased branded data protection revenue 7 percent and improved our GAAP and non-GAAP bottom-line results by approximately $28 million and $23 million, respectively.

“We ended the quarter with excellent momentum across all product categories, and we start our fiscal fourth quarter with a strong backlog and solid funnel. Therefore, we feel very confident in our ability to deliver year-over-year revenue growth again in the current quarter and exceed our annual revenue and profitability guidance for fiscal 2017.”

Quantum will issue a news release on its fiscal third quarter financial results on Wednesday, Jan. 25, 2017, after the close of the market. The company will also hold a conference call and live audio webcast to discuss these results that same day at 2:00 p.m. PST. Press and industry analysts are invited to attend in listen-only mode.

“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, statements relating to: i) our expected financial results for the fiscal third quarter 2017 and for the first three quarters of fiscal 2017; and ii) our confidence in our ability to deliver year-over-year revenue growth again in the current quarter and exceed our annual revenue and profitability guidance for fiscal 2017, 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. More detailed information about these 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

Quantum believes that the non-GAAP financial measures disclosed above provide useful and supplemental information to investors regarding its quarterly financial performance. Quantum management and Board of Directors use 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.

This includes acquired intangibles such as purchased technology 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 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. 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 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.

Proxy contest and related costs are expenses incurred to respond to activities and inquiries of VIEX Capital Advisors, LLC, including their proxy solicitation. These costs are not considered core operating activities. 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.

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.

The loss (gain) on debt extinguishment relates to specific actions undertaken during the third quarter of fiscal 2017. The loss and gain are excluded from non-GAAP financial measures because they are not considered a core operating activity and management believes that it is appropriate to exclude the loss and gain in order to provide investors the ability to compare Quantum’s period-over-period 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.
