QUANTUM CORPORATION REPORTS FISCAL THIRD QUARTER RESULTS

Highlights:

• Total revenue of $146 million, up 11% sequentially
  
• Sequential increase in branded tape automation and DXi revenue of 37% and 32%, respectively
  
• 20% year-over-year growth in StorNext and related service revenue, driven by near doubling of North America sales
  
• Year-over-year improvement in GAAP and non-GAAP net income of 70% and 27%, respectively, on 8% revenue decline

SAN JOSE, Calif., Jan. 29, 2014 – Quantum Corp. (NYSE:QTM) today reported results for the third quarter of fiscal 2014, ended Dec. 31, 2013. Revenue for the quarter was $145.9 million, down 8 percent from the third quarter of fiscal 2013, primarily due to lower tape automation revenue and a decline in DXi^® sales from the record DXi quarter a year earlier. On a sequential basis, total revenue was up 11 percent and, as previously announced, above the high end of the guidance range provided in the company’s Oct. 23, 2013 earnings announcement. Product highlights included growth in StorNext^® and related service revenue of 20 percent year-over-year and 5 percent over the prior quarter, as well as sequential increases in branded Scalar^® tape automation and DXi sales of 37 percent and 32 percent, respectively.

On a GAAP basis, Quantum reported breakeven operating income for the quarter, better than the $5.7 million operating loss a year earlier, and had a net loss of $2.4 million, or $0.01 per diluted share, compared to a net loss of $8.2 million in the prior year, a 70 percent improvement. On a non-GAAP basis, the company generated $8.6 million of operating income, up $1.2 million year-over-year. Finally, Quantum reported non-GAAP net income of $6.2 million, or $0.02 per diluted share, approximately $1.3 million, or 27 percent, higher than a year earlier. The operating and net income results were better than the high end of the third quarter guidance given in October.

“Our December quarter results reflect our focus on driving increased profitability and cash flow while capitalizing on revenue opportunities,” said Jon Gacek, president and CEO of Quantum. “We reduced our GAAP operating expenses by 17 percent year-over-year – and 12 percent on a non-GAAP basis – improving our bottom-line results and helping us end the quarter with our highest cash balance in three years. At the same time we continued to increase our StorNext revenue, with particularly strong year-over-year growth driven by a near doubling of sales in North America, and significantly improved our DXi and tape automation revenue performance over the prior quarter. Moving forward, we will maintain a balanced approach between growth and profit, building on our expanding product portfolio and market reach and the actions we’ve taken to reduce our cost structure.”

Quantum generated $7.3 million in cash from operations in the quarter, ending the quarter with $82.8 million in total cash and cash equivalents.

Outlook

For the fourth quarter of fiscal 2014, Quantum expects:

• Revenue of approximately $125 million to $130 million.
   
• GAAP gross margin of 42 to 43 percent and non-GAAP gross margin of 43 to 44 percent.
   
• GAAP operating expenses of $60 million to $61 million and non-GAAP operating expenses of $55 million to $56 million.
   
• Interest expense of $2.5 million and taxes of $500,000.

The company noted that its fourth quarter operating expense guidance is $10 million to $11 million lower than actual operating expenses on a GAAP basis in the comparable quarter a year ago and $7 million to $8 million lower on a non-GAAP basis. Quantum also reiterated that it expects approximately $16 million to $18 million of additional annual expense savings from the outsourcing of manufacturing operations and staffing reductions announced earlier this month to be reflected in the company’s results beginning in the fiscal first quarter of 2015 (June 2014 quarter). The company will provide guidance for fiscal 2015 when it reports its fourth quarter results.

Business Highlights

Key business highlights for the December quarter include the following:

• Based on the integration of the company’s Lattus™ Object Storage with Rocket Arkivio data archiving software, Quantum announced a new solution to reduce primary storage and backup costs by archiving static, unstructured data. Customers using the combined solution can save 30 percent or more in annual storage expenses and, in many cases, pay back their investment within a year.
   
• The company introduced a new program enabling managed service providers (MSPs) and value added resellers (VARs) to expand their businesses with a cloud backup service powered by Quantum’s DXi virtual deduplication appliances and vmPRO™ backup software. Through unique capacity-based subscription pricing, the program allows MSPs and VARs to brand, market and sell cloud backup-as-a-service offerings that scale as their revenues grow, thereby reducing the need for large up-front capital expenditures on hardware.
   
• Quantum continued to receive industry accolades, reinforcing the compelling benefits and overall value it provides to customers and partners. The company and its Lattus Object Storage solution were named as finalists for 2014 Storage Visions Awards, which honor excellence and innovation in media and entertainment technology. The Lattus solution also received honorable mention in the Tiered Storage Product of the Year category at the 2013 Storage Virtualization Cloud Awards. At these same awards, the Quantum Alliance reseller program was also selected as “Vendor’s Reseller Channel Program of the Year.”

“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 our priorities and focuses for the fourth quarter of our fiscal year, that we will maintain our balanced approach to driving increased profit and cash flow while pursuing revenue growth and 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 7, 2013 and in Quantum’s Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on November 12, 2013.

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.

-more-

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.

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

In the first quarter of fiscal year 2014, Quantum identified an error related to the accounting for certain allowances for estimated future price adjustments to customers which impacted prior reporting periods. As a result, the company’s financial statements for the third quarter and first nine months of fiscal 2013 have been revised. For additional information, refer to our Form 10-Q filed with the Securities and Exchange Commission on November 12, 2013.

‡ Non-GAAP per share net income (loss): Each fiscal period is calculated independently, thus the sum of each of the quarter's non-GAAP per diluted share net income (loss) does not necessarily equal the year-to-date non-GAAP per diluted share net income (loss). For example, certain convertible subordinated notes were anti-dilutive in the second quarter of fiscal 2014 but were dilutive for the year-to-date period.
