NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)

NOTE 1: BASIS OF PRESENTATION

Quantum Corporation (“Quantum”, the “Company”, “us” or “we”) (NYSE: QTM), founded in 1980, is a global expert in data protection and big data management. Combining focused expertise, customer-driven innovation and platform independence, we provide a comprehensive, integrated range of disk, tape and software solutions to solve data protection and big data management challenges supported by our sales and service organization. We work closely with a broad network of distributors, value-added resellers (“VARs”), direct marketing resellers, original equipment manufacturers (“OEMs”) and other suppliers to meet customers’ evolving data protection and big data management needs.

The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Quantum and its wholly-owned subsidiaries. On June 13, 2011, we acquired Pancetera Software, Inc. (“Pancetera”), and Pancetera’s results of operations are included in our Condensed Consolidated Statement of Operations from that date. All intercompany balances and transactions have been eliminated. The interim financial statements reflect all adjustments, consisting of normal recurring adjustments that, in the opinion of management, are necessary for a fair statement of the results for the periods shown. The results of operations for such periods are not necessarily indicative of the results expected for the full fiscal year. The Consolidated Balance Sheet as of March 31, 2011 has been derived from the audited financial statements at that date. However, it does not include all of the information and notes required by accounting principles generally accepted in the United States for complete financial statements. The accompanying financial statements should be read in conjunction with the audited Consolidated Financial Statements for the fiscal year ended March 31, 2011 included in our Annual Report on Form 10-K, as filed with the Securities and Exchange Commission on June 14, 2011.

NOTE 2: SIGNIFICANT ACCOUNTING POLICIES; NEW ACCOUNTING STANDARDS

Significant Accounting Policies

Except for the business combination policy noted below, the significant accounting policies used in the preparation of our Condensed Consolidated Financial Statements are unchanged and are disclosed in our Annual Report on Form 10-K for the year ended March 31, 2011, as filed with the Securities and Exchange Commission on June 14, 2011.

We allocate the purchase price paid to the assets acquired and liabilities assumed in a business combination at their estimated fair values as of the acquisition date. Any excess purchase price above the identified net tangible and intangible assets and assumed liabilities is allocated to goodwill. We consider fair value to be the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy is used to assess the fair value of assets acquired and liabilities assumed. We evaluate the tangible and intangible assets as well as liabilities and contingencies of the acquired company.

New Accounting Standards Adopted

In the first quarter of fiscal 2012, we adopted the goodwill impairment guidance for reporting units with zero or negative carrying amounts. Adoption of this standard did not have an impact on our financial position or results of operations.

In the first quarter of fiscal 2012, we adopted the guidance for disclosure of supplementary pro forma information for business combinations. Adoption of this standard did not have an impact on our financial position or results of operations, other than the additional disclosures included in the notes to the Condensed Consolidated Financial Statements.

Recent Accounting Pronouncements

In May 2011, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2011-04, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs (“ASU 2011-04”), which amends the accounting standards for fair value measurements and disclosures. ASU 2011-04 provides clarifications about the application of existing fair value measurement and disclosure requirements. In addition, ASU 2011-04 changes how to measure fair value of financial instruments managed within a portfolio and how to apply premiums and discounts. There are also additional disclosures required. ASU 2011-04 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011. We will apply this standard beginning in fiscal 2013 and do not anticipate adoption will impact our statements of financial position or results of operations.

In June 2011, the FASB issued Accounting Standards Update No. 2011-05, Comprehensive Income (Topic 220): Presentation of Comprehensive Income (“ASU 2011-05”). ASU 2011-05 requires that components of other comprehensive income be presented in a single continuous statement of comprehensive income or in two separate but consecutive statements of net income and its components followed immediately by a statement of total other comprehensive income. ASU 2011-05 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2011; however, reclassification adjustments have been deferred. We will apply this standard beginning in fiscal 2013 and, as this affects presentation only, adoption will not impact our statements of financial position or results of operations.

In September 2011, the FASB issued Accounting Standards Update No. 2011-08, Intangibles—Goodwill and Other (Topic 350) Testing Goodwill for Impairment (“ASU 2011-08”). ASU 2011-08 provides entities the option to perform a qualitative assessment for step one impairment testing. ASU 2011-08 is effective for fiscal years beginning after December 15, 2011; however, early adoption is permitted if the current fiscal year test has not been performed. We are considering early adopting ASU 2011-08 and do not anticipate adoption will impact our statements of financial position or results of operations.

On June 13, 2011, we acquired Pancetera in order to enhance our product offerings and technology portfolio pursuant to a statutory merger in exchange for approximately $11.0 million, comprised of $8.2 million in cash and $2.8 million in Quantum common stock. We acquired all outstanding shares of Pancetera and assumed all of Pancetera’s outstanding unvested stock options according to the option exchange ratio defined in the merger agreement with Pancetera. We also assumed unvested restricted Pancetera common stock in accordance with the merger agreement. Pancetera’s results of operations are included in our Condensed Consolidated Statements of Operations and Cash Flows from the June 13, 2011 acquisition date.

The acquisition was recorded under the acquisition method of accounting, resulting in the purchase price being allocated to the assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase price over the assets acquired and liabilities assumed was recorded as goodwill. The preliminary allocation of assets acquired and liabilities assumed is set forth below (in thousands):

Current assets	$	46
Property and equipment		37
Amortizable intangible assets		1,795
In-process research and development		349
Goodwill		8,843
Current liabilities		(116	)
Total purchase price	$	10,954

In performing our purchase price allocation, we considered, among other factors, our intention for future use of acquired assets, analyses of historical financial performance and estimates of future performance of Pancetera’s existing and future products. The fair value of current assets, property and equipment and current liabilities was based on market prices at the acquisition date. The fair value of amortizable intangible assets and in-process research and development (“IPR&D”) was based, in part, on a valuation using a discounted cash flow approach and other valuation techniques as well as management’s estimates and assumptions.

The amortizable intangible assets are all related to developed technology and are included in purchased technology within Note 6: “Intangible Assets and Goodwill.” Purchased technology, which comprises products that have reached technological feasibility, was primarily related to SmartRead®. SmartRead is patented technology, primarily comprised of a set of algorithms that reduce storage input-output when performing maintenance tasks such as backup, replication or migration of virtual machines. Pancetera products containing the SmartRead technology included SmartView TM and SmartMotion TM, which have been rebranded as vmPRO software solutions. Purchased technology intangible assets also include a combination of Pancetera processes, patents and trade secrets related to the design and development of these products. This proprietary know-how can be leveraged to develop new technology and improve our products. The SmartRead purchased technology intangible asset has an amortization period of four years.

IPR&D represents incomplete Pancetera research and development projects that had not reached technological feasibility as of the acquisition date. Due to the nature of IPR&D, the expected life is indeterminate and we will periodically evaluate for attainment of technological feasibility or impairment. Technological feasibility is established when an enterprise has completed all planning, designing, coding and testing activities that are necessary to establish that a product can be produced to meet its design specifications including functions, features and technical performance requirements. The value assigned to IPR&D was determined by considering the importance of each project to our overall development plan, estimating costs to develop the purchased IPR&D into commercially viable products, estimating the resulting net cash flows from the projects when completed and discounting the net cash flows using a discount rate of 18% to their present value based on the percentage of completion of the IPR&D projects.

The goodwill as a result of this acquisition is not expected to be deductible for tax purposes. The results of operations for the second quarter and first six months of fiscal 2012 included immaterial revenue and a $1.0 million and $1.1 million net loss, respectively, of Pancetera since the acquisition date. In addition, we incurred acquisition expenses of $0.1 million and $0.3 million during the second quarter and first six months of fiscal 2012, respectively, which are included in general and administrative expense in our Condensed Consolidated Statements of Operations.

The following unaudited supplemental pro forma information presents the combined results of operations of Quantum and Pancetera as if the acquisition had occurred as of the beginning of fiscal 2011. The second quarter and first six months of fiscal 2011 supplemental pro forma earnings were adjusted to include $0.1 million and $1.0 million, respectively, in nonrecurring acquisition expenses incurred in the second quarter and first six months of fiscal 2012. These amounts have been excluded from the second quarter and first six months of fiscal 2012 supplemental pro forma earnings (in thousands):

	Three Months Ended				Six Months Ended
	September 30, 2011		September 30, 2010		September 30, 2011			September 30, 2010
Pro forma revenue	$	165,039	$	167,739	$	318,607		$	330,964
Pro forma net income (loss)	$	3,655	$	1,665	$	(2,319	)	$	(2,929	)

The assets acquired and liabilities assumed from Pancetera were recorded at their respective fair values on the acquisition date. The following fair value disclosures are in regard to the remainder of our assets and liabilities.

The assets measured and recorded at fair value on a recurring basis consist of money market funds which are valued using quoted market prices for similar assets at the respective balance sheet dates and are level 2 fair value measurements (in thousands):

		September 30, 2011			March 31, 2011
Money market funds		$	37,030		$	68,560

We have certain non-financial assets that are measured at fair value on a non-recurring basis when there is an indicator of impairment, and they are recorded at fair value only when an impairment is recognized. These assets include property and equipment, amortizable intangible assets, IPR&D and goodwill. We did not record impairments to any non-financial assets in the second quarter or first six months of fiscal 2012 or 2011. We do not have any non-financial liabilities measured and recorded at fair value on a non-recurring basis.

We have financial liabilities for which we are obligated to repay the carrying value. The carrying value and fair value of these financial liabilities at September 30, 2011 and March 31, 2011 were as follows (in thousands):

	September 30, 2011				March 31, 2011
	Carrying Value		Fair Value		Carrying Value		Fair Value
Credit Suisse term loan(1)	$	68,814	$	67,437	$	104,334	$	103,812

Component parts		20,474		19,688
	$	42,705	$	45,036

NOTE 6: INTANGIBLE ASSETS AND GOODWILL

Intangible assets are evaluated for impairment whenever indicators of impairment are present. During the second quarter of fiscal 2012 and 2011, we considered whether there were any indicators of impairment for both our goodwill and our long-lived assets, including amortizable and indefinite-lived intangible assets, and determined there were none.

The following provides a summary of the carrying value of amortizable intangible assets (in thousands):

	As of September 30, 2011							As of March 31, 2011
	Gross Amount		Accumulated Amortization			Net Amount		Gross Amount		Accumulated Amortization			Net Amount
Purchased technology	$	189,962	$	(181,027	)	$	8,935	$	188,167	$	(176,350	)	$	11,817
Trademarks		27,260		(26,691	)		569		27,260		(26,316	)		944
Non-compete agreements		500		(500	)		—		500		(468	)		32
Customer lists		106,419		(80,741	)		25,678		106,419		(74,501	)		31,918
	$	324,141	$	(288,959	)	$	35,182	$	322,346	$	(277,635	)	$	44,711

Total intangible amortization expense was $5.4 million and $11.3 million for the three and six months ended September 30, 2011, respectively, and was $7.5 million and $16.5 million for the three and six months ended September 30, 2010, respectively.

We evaluate goodwill for impairment annually during the fourth quarter of our fiscal year, or more frequently when indicators of impairment are present. The following provides a summary of the carrying value of goodwill (in thousands):

	Six Months Ended September 30, 2011
Beginning balance as of March 31, 2011
Goodwill	$	385,770
Accumulated impairment losses		(339,000	)
		46,770

Ending balance as of September 30, 2011
Goodwill		394,613
Accumulated impairment losses		(339,000	)
	$	55,613

NOTE 7: ACCRUED WARRANTY

The quarterly and year-to-date changes in the accrued warranty balance were (in thousands):

	Three Months Ended						Six Months Ended
	September 30, 2011			September 30, 2010			September 30, 2011			September 30, 2010

Ending balance	$	7,113		$	6,214		$	7,113		$	6,214

We generally warrant our products against defects from 12 to 36 months. A provision for estimated future costs and estimated returns for credit relating to warranty is recorded when products are shipped and revenue recognized. Our estimate of future costs to satisfy warranty obligations is primarily based on historical trends and, if believed to be significantly different from historical trends, estimates of future failure rates and future costs of repair including materials consumed in the repair, labor and overhead amounts necessary to perform the repair. If future actual failure rates differ from our estimates, we record the impact in subsequent periods. If future actual costs to repair were to differ significantly from our estimates, we record the impact of these unforeseen cost differences in subsequent periods.

NOTE 8: RESTRUCTURING CHARGES

In fiscal 2011 and continuing in fiscal 2012, restructuring actions to consolidate operations supporting the business were the result of strategic management decisions. The types of restructuring expense (benefit) for the three and six months ended September 30, 2011 and 2010 were (in thousands):

	Three Months Ended					Six Months Ended

During the second quarter and first six months of fiscal 2012, we accrued severance charges for various positions eliminated worldwide. Facility restructuring charges for both the second quarter and first six months of fiscal 2012 were due to estimated charges for a facility in India that we vacated in the second quarter of fiscal 2012. The other restructuring reversal for the first six months of fiscal 2012 was due to actual payments lower than estimated on a supplier relationship exited in fiscal 2011.

During the second quarter of fiscal 2011, facilities restructuring expense was primarily due to negotiating a lease modification for a U.S. location. For the six months ended September 30, 2010, severance and benefits expense from additional positions eliminated was offset by facility reversals. The facility reversals were primarily due to negotiating settlements for lease liabilities on two vacated facilities in the U.S. for amounts lower than the outstanding lease contracts.

NOTE 9: STOCK INCENTIVE PLANS AND SHARE-BASED COMPENSATION

Our stock incentive plans (“Plans”) are broad-based, long-term retention programs that are intended to attract and retain talented employees and align stockholder and employee interests. The Plans provide for the issuance of stock options, stock appreciation rights, stock purchase rights and long-term performance awards to our employees, officers and affiliates. We also have an employee stock purchase plan (“Purchase Plan”) that allows for the purchase of stock at 85% of fair market value at the date of grant or the exercise date, whichever value is less.

During the first quarter of fiscal 2012, we assumed outstanding unvested options and unvested restricted shares of Pancetera which were exchanged into options and unvested restricted shares of Quantum common stock, respectively, in accordance with the merger agreement. As of June 13, 2011, Pancetera had approximately 0.8 million unvested stock options and 0.5 million unvested restricted shares outstanding. Based on the exchange ratio of 0.2403 calculated in accordance with the formula in the merger agreement, we assumed the outstanding unvested options, which are exercisable for an aggregate of 194,000 shares of Quantum common stock. Based on the relative cash and stock consideration for Pancetera shares per the merger agreement, the unvested restricted shares became 33,000 unvested restricted shares of Quantum common stock and $200,000 in cash held in escrow. The estimated fair value of unvested Pancetera options, unvested restricted shares and cash held in escrow related to future service is being recognized over the remaining service period.

The Black-Scholes option pricing model is used to estimate the fair value of options granted under our Plans, options assumed and rights to acquire stock granted under our Purchase Plan.

No stock options were granted in the second quarter of fiscal 2012 and 2011. The weighted-average grant date fair values of employee stock option grants, as well as the weighted-average assumptions used in calculating these values for the first six months of fiscal 2012 and 2011, were based on estimates at the date of grant as follows:

	Three and Six Months Ended
	September 30, 2011		September 30, 2010
Option life (in years)		4.0		4.2
Risk-free interest rate		1.57%		2.02%
Stock price volatility		112.33%		106.75%
Weighted-average grant date fair value	$	1.91	$	1.96

The weighted-average fair value of stock options assumed from Pancetera, as well as the weighted-average assumptions used in calculating these values were based on estimates at the acquisition date as follows:

Option life (in years)		5.2
Risk-free interest rate		1.65%
Stock price volatility		100.93%
Weighted-average grant date fair value	$	2.67

The assumed options have a 10 year contractual life from the original grant date.

The fair value of the restricted stock units granted is the intrinsic value as of the respective grant date since the restricted stock units are granted at no cost to the employees. The weighted-average grant date fair values of restricted stock units granted during the second quarter and first six months of fiscal 2012 were $3.25 and $3.19, respectively. The weighted-average grant date fair values of restricted stock units granted during the second quarter and first six months of fiscal 2011 were $1.82 and $1.93, respectively.

Under the Purchase Plan, rights to purchase shares are typically granted during the second and fourth quarter of each fiscal year. The value of rights to purchase shares granted in the second quarter and first six months of fiscal 2012 and fiscal 2011, respectively, was estimated at the date of the grant. The weighted-average grant date fair values and the assumptions used in calculating fair values for the three and six month periods ended September 30, 2011 and 2010 are as follows:

	Three and Six Months Ended
	September 30, 2011		September 30, 2010

NOTE 10: INCOME TAXES

Income tax provisions for the second quarter and first six months of fiscal 2012 were $0.3 million and $0.9 million, respectively, and were $0.4 million and $0.8 million for the second quarter and first six months of fiscal 2011, respectively. Income tax provisions for each of these periods reflect expenses for foreign income taxes and state taxes.

We have provided a full valuation allowance against our U.S. net deferred tax assets due to our history of net losses, difficulty in predicting future results and our conclusion that we cannot rely on projections of future taxable income to realize the deferred tax assets. Significant management judgment is required in determining our deferred tax assets and liabilities and valuation allowances for purposes of assessing our ability to realize any future benefit from our net deferred tax assets. We intend to maintain this valuation allowance until sufficient positive evidence exists to support a reversal or decrease in this allowance. Future income tax expense will be reduced to the extent that we have sufficient positive evidence to support a reversal of, or decrease in, our valuation allowance.

Quantum Corporation (“Quantum”, the “Company”, “us” or “we”), founded in 1980, is a global expert in data protection and big data management. Combining focused expertise, customer-driven innovation and platform independence, we provide a comprehensive, integrated range of disk, tape and software solutions to solve data protection and big data management challenges supported by our sales and service organization. We work closely with a broad network of distributors, value-added resellers (“VARs”), direct marketing resellers, original equipment manufacturers (“OEMs”) and other suppliers to meet customers’ evolving data protection and big data management needs. Our stock is traded on the New York Stock Exchange (“NYSE”) under the symbol “QTM.”

We offer a comprehensive range of solutions for data protection and big data management challenges providing performance and value to organizations of all sizes, from small businesses to multinational enterprises. We believe our combination of expertise, innovation and platform independence allows us to solve customers’ data protection and big data management issues more easily, effectively and securely. Our open systems solutions are designed to provide significant storage efficiencies and cost savings while minimizing risk and protecting customers’ prior investments. They include the DXi®-Series disk-based deduplication and replication systems for fast backup and restore, Scalar® tape automation products for disaster recovery and long-term data retention, StorNext® data management software and appliances for high-performance file sharing and archiving and vmPRO™ solutions for protecting virtual machine data. In addition, we have the global scale and scope to support our worldwide customer base. We offer a full range of service with support available in more than 100 countries.

We earn our revenue from the sale of products, systems and services through our sales force and an array of channel partners to reach end user customers, which range in size from small businesses to multinational enterprises. Our products are sold under both the Quantum brand name and the names of various OEM customers. We have a broad portfolio of disk systems, software solutions, tape automation systems, tape drives and other devices and media. Our data management software provides technology for shared workflow applications and multi-tiered archiving in high-performance, large-scale storage environments. The majority of our disk systems and tape automation systems include software features that provide disk and tape integration capabilities with our core deduplication and replication technologies. In addition, our service offerings include a broad range of coverage options to provide the level of support for the widest possible range of information technology (“IT”) environments.

We have implemented a number of initiatives in the past several quarters in an effort to drive branded revenue growth. One key initiative for fiscal 2012 has been to grow the independent channel for Quantum branded products. Another key area of focus for fiscal 2012 is continuing to expand and improve our products and solutions, with emphasis on branded disk systems and software solutions, including introducing and ramping sales of the StorNext appliance family and expanding professional services and custom engineering. We believe our current tape automation systems, disk systems and software solutions provide excellent value propositions for customers and we plan to continue to expand the breadth and depth of our product and service offerings in fiscal 2012. We are focused on advancing these objectives to take advantage of our improved position in the markets in which we participate to grow revenue in fiscal 2012 and create shareholder value.

We stated that for the second quarter of fiscal 2012, we were focused on growing revenue by improving our sales and go-to-market execution, including our overall product and solution messaging with channel partners. We had sequential improvement across our targeted product lines and sales channels for increased revenue in the second quarter of fiscal 2012. Our execution of these initiatives was reflected in an expansion of the independent channel for Quantum products in the second quarter of fiscal 2012. This growth was reflected in two metrics: increased revenue from products sold by our top tier channel partners and an increase in the number of channel partners. Product revenue from our top tier channel partners more than doubled from the first quarter of fiscal 2012, primarily due to sales of our DXi-Series systems in addition to increased revenue from sales of tape automation products. We also had a sequential increase in the number of channel partners that sold our DXi disk systems. This growth of the independent channel was positively impacted by the launch of the DXi6701 and 6702 in the second quarter of fiscal 2012.

As noted above, one key area of focus is continuing to expand and improve our products and solutions, with emphasis on branded disk systems and software solutions as well as introducing our initial StorNext appliances. During the second quarter of fiscal 2012, we continued to expand and improve our product portfolio. Notable new product introductions included the DXi6701 and 6102, vmPRO 4000-series and the vmPRO software solution. In addition, we expanded the StorNext appliance family with the introduction of the StorNext Archive Enabled Library (“SAEL”), and had our first full quarter of sales of the M330 appliance.

We have also started to position our products as they relate to two distinct market opportunities, namely data protection and big data management and archive. Our data protection solutions include our DXi-Series family of products, Scalar tape automation products, devices and media as well as virtual environment offerings that include vmPRO software and the vmPRO 4000-series. The products that solve big data management and archive issues include StorNext software and our StorNext appliances.

In July 2011, we announced availability of the DXi6701 and DXi6702 products which incorporate the DXi 2.0 software and provide a unique approach to distributed, or hybrid, deduplication to provide data protection solutions. These products are designed to protect customers’ prior investments and provide flexibility for future backup architectures. In addition, with these new products, the DXi 2.0 software has been incorporated across our midrange disk offerings, which enables clearer and simpler product positioning of our midrange products with our channel partners. We believe the introduction of these products helped improve our win rates in the second quarter of fiscal 2012 and increase midrange disk systems product revenue. The DXi 6701 and 6702 product introduction has been one of our most successful branded product introductions in terms of revenue and units sold in the first quarter of availability.

In August 2011, we introduced the vmPRO 4510, an all-in-one data protection solution designed to simplify backups in virtual environments. It includes both backup software and integrated storage with deduplication in a single solution that is designed for small to medium-size businesses and remote offices. The vmPRO 4510 is the first product in the vmPRO 4000-series that are a result of building on our data protection expertise by combining the technologies of Pancetera Software, Inc. (“Pancetera”), which we acquired in June 2011, and Quantum to meet customers' evolving storage needs in the data protection market.

As a result of our acquisition of Pancetera, we also offer vmPRO software, a virtualization data protection software with advanced utilities designed to dramatically improve and simplify virtual data protection in midrange and larger data centers. It works with our DXi family of deduplication products to accelerate backup, restore, and disaster recovery protection in data center virtual environments while reducing IT costs.

The second quarter of fiscal 2012 was the first full quarter of availability for the M330, our initial StorNext appliance. We added the SAEL to our StorNext appliance family in the second quarter of fiscal 2012, and it had initial success in its first quarter of availability. The SAEL is designed to provide big data management and archive solutions, especially for deep archive situations. In the second quarter of fiscal 2012, we also announced an expansion of our StorNext family of appliances with the QM1200, QS1200 and QD6000 to provide big data management and archive solutions. These solutions will become available in our fiscal third quarter of fiscal 2012.

For the third quarter and second half of fiscal 2012, we are focused on continuing to grow revenue by expanding the breadth of our product portfolio, including the introduction of several new products as well as continuing to increase sales through channel partners. We have already introduced several new products and expanded capabilities to existing solutions in October 2011. We believe the key to revenue growth is to continue to leverage our expertise as well as our intelligent and unique solutions to provide customers superior value to meet their needs in data protection and big data management and archive. We expect to achieve sequential growth in revenue from our branded products, largely from growth in disk systems and software solutions in addition to better than market growth in branded tape automation by continuing to increase market share. We also expect slightly higher gross margins in the third quarter of fiscal 2012 than the second quarter of fiscal 2012.

In addition, we continue to monitor opportunities to improve our capital structure and to make principal prepayments on our senior term debt. In late July 2011, Standard & Poor's Rating Services upgraded its outlook on Quantum from stable to positive based on our ongoing debt reduction and prospects for sustained lower debt leverage levels.

Revenue decreased $2.7 million, or 2%, in the second quarter of fiscal 2012 compared to the second quarter of fiscal 2011 primarily due to expected reductions in royalty and OEM revenue. The royalty revenue decrease was primarily from maturing DLT media. Product revenue from OEM customers decreased 12% as expected while revenue from branded products increased 7% from the second quarter of fiscal 2011 due to continued improvement in revenue momentum with our partners. Our efforts to increase revenue from branded disk systems and software solutions resulted in an 18% increase from the second quarter of fiscal 2011, primarily due to midrange disk system revenue increases as well as the addition of revenue from the recently introduced family of StorNext appliances, such as the SAEL and M330. In addition, branded tape automation revenue increased 5% in a declining market, an indicator of growing our market share. Service revenue decreased primarily due to lower hardware service contract revenues from end of service life on higher revenue service contracts for certain legacy branded tape automation products. Our focus on growing the branded business in recent years is reflected in the greater proportion of non-royalty revenue from our branded business, at 82% in the second quarter of fiscal 2012 compared to 80% in the second quarter of fiscal 2011.

Our gross margin percentage increased 80 basis points in the second quarter of fiscal 2012 to 43.4% primarily due to decreased intangible amortization in the second quarter of fiscal 2012 from certain intangibles becoming fully amortized in the current and prior year. This was largely offset by decreased total revenue and changes in our revenue mix, including decreased royalty revenue. Product gross margin percentage increased 220 basis points from the second quarter of fiscal 2011, primarily due to decreased intangible amortization. Service gross margin percentage increased 270 basis points primarily due to decreased costs from bringing repair of certain product lines in-house.

Operating expenses increased 6% to $66.2 million for the second quarter of fiscal 2012 primarily due to increased salaries and benefits from investing in our sales and marketing and research and development teams. We had other operating income from a $1.5 million gain on sale of patents. Under the patent sale agreement, we retain a royalty-free license for these patents. We may enter into similar transactions in the future. Income from operations was $6.9 million for a 4.2% operating margin in the second quarter of fiscal 2012 compared to a 5.4% operating margin in the second quarter of fiscal 2011.

Interest expense decreased $3.1 million, or 53%, compared to the second quarter of fiscal 2011 primarily due to refinancing higher rate subordinated term debt with convertible subordinated notes in fiscal 2011 and to a lesser extent from continued principal prepayments of senior term debt. We generated $5.6 million in cash from operating activities in the second quarter of fiscal 2012, paid $30.3 million on the senior term debt and ended the quarter with $49.5 million in cash and cash equivalents, including restricted cash. Our outstanding senior term debt balance was $68.8 million at September 30, 2011.

Total revenue	$	318,574	100.0%	$	330,947	100.0%	$	(12,373	)	(3.7	)%

Total revenue decreased in the second quarter of fiscal 2012 primarily due to anticipated decreases in royalty and OEM revenue. However, revenue increased from the first quarter of fiscal 2011 primarily due to branded product sales increases in North America, including federal sales territories, as well as Europe and Asia. For the first six months of fiscal 2012 total revenue decreased, primarily reflecting expected declines in OEM revenue. In addition, revenue decreases for the first half of fiscal 2012 were impacted by economic uncertainty in Europe from canceled or delayed sales; however, we saw sequential revenue improvement in Europe in the second quarter of fiscal 2012.

The third quarter of fiscal 2012 is expected to reflect typical seasonal strength; however, we continue to face risk associated with economic uncertainty that could result in end user customers delaying purchase decisions and downsizing configurations due to budget constraints. We believe the underlying market demand exists to support increased revenue and that our product portfolio is strong and will support revenue growth in both the third quarter and second half of fiscal 2012. In addition, we believe our internal sales and external channel initiatives will contribute to revenue growth. We anticipate increased total revenue for the third quarter of fiscal 2012 compared to the second quarter of fiscal 2012 and for the second half of fiscal 2012 compared to the first half of fiscal 2012. We project revenue growth for our branded products, primarily from disk systems and software solutions as well as tape automation systems.

Our product revenue, which includes sales of our hardware and software products sold through both our Quantum branded and OEM channels, increased $2.8 million in the second quarter of fiscal 2012 compared to the second quarter of fiscal 2011 primarily due to increased branded disk systems and software solutions revenue. Product revenue decreased $3.4 million compared to the first six months of fiscal 2011 primarily due to an anticipated decrease in OEM deduplication software revenue, partially offset by an increase in branded disk systems and software solutions revenue. Revenue from sales of branded products increased 7% in both the second quarter and first six months of fiscal 2012, compared to the second quarter and first six months of fiscal 2011.

As noted earlier, a primary goal for fiscal 2012 is to grow revenue from disk systems and software solutions. For the second quarter of fiscal 2012, disk systems and software solutions revenue increased 16% compared to the second quarter of fiscal 2011 primarily due to sales of the DXi6700-Series disk systems. Midrange disk systems revenue nearly tripled from the second quarter of fiscal 2011, and the addition of revenue from our new StorNext appliances contributed approximately 30% of the revenue increase in disk systems and software solutions in the second quarter of fiscal 2012. These were partially offset by a decrease in enterprise disk systems revenue from a large customer sale in the prior year that was not repeated. As a result of these revenue increases, disk systems and software solutions comprised a greater proportion of both product revenue and total revenue in the second quarter of fiscal 2012 compared to the second quarter of fiscal 2011.

For the first six months of fiscal 2012, disk systems and software solutions revenue decreased 6% largely due to the expected decrease in OEM deduplication software revenue due to revenue recognized in accordance with contractual requirements in the first quarter of fiscal 2011 and to a lesser extent from decreased enterprise disk systems revenue. Partially offsetting this decrease was increased sales of branded disk systems and software solutions, largely from midrange disk systems and the newly introduced StorNext appliances. As noted above, we continue to expect revenue from our branded disk systems and software solutions to be a significant driver of growth for the remainder of fiscal 2012.

Tape automation systems revenue was approximately the same in the second quarter and first six months of fiscal 2012 as the comparable prior year periods. Branded tape automation systems revenue increased 5% and 6% in the second quarter and first six months of fiscal 2012, respectively, primarily due to increased enterprise sales and to a lesser extent from midrange sales. Midrange and entry level tape automation systems revenue from OEM customers decreased as anticipated in the second quarter and first six months of fiscal 2012 compared to the prior year periods, while OEM enterprise tape automation product sales increased compared to the prior year periods.

Product revenue from devices, which includes tape drives and removable hard drives, and non-royalty media sales declined 5% and 1% from the second quarter and first six months of fiscal 2011, respectively, primarily due to anticipated decreases in sales of older technology, including branded and OEM devices that reached, or are nearing, end of life. These decreases were partially offset by increased branded media sales in the second quarter and first six months of fiscal 2012 compared to the same periods in fiscal 2011. The increase in branded media revenue is primarily due to the events in Japan earlier this year and resulting concern of shortages and supply disruption in the market. Consistent with our expectations, revenue from OEM devices has become an insignificant part of our overall revenue mix.

Service Revenue

Service revenue includes revenue from sales of hardware service contracts, product repair, installation and professional services. Hardware service contracts are typically purchased by our customers to extend their warranties, to provide faster service response times, or both. Service revenue decreased 5% in both the second quarter and the first six months of fiscal 2012 compared to the prior year periods primarily due to lower hardware service contract revenues from end of service life on higher revenue service contracts for certain legacy branded tape automation products and to a lesser extent from decreased OEM product repair services. Service contracts on certain newer technology products provide lower revenue than service contracts on older technology products nearing end of service life.

Royalty Revenue

Tape media royalties decreased 21% and 15% in the second quarter and first six months of fiscal 2012, respectively, compared to the second quarter and first six months of fiscal 2011 primarily due to decreased media unit sales by media licensees. Royalties from maturing DLT media in the three and six months ended September 30, 2011 was the primary driver of the declines. These decreases were largely from a continued worldwide decline in demand for older media technology. We continue to expect declining market demand for maturing DLT media and associated tape media royalties. However, we anticipate decreases in DLT royalties to become smaller in future periods, largely because DLT media royalties comprise a smaller proportion of our royalty revenue.

The 80 basis point increase in gross margin percentage for the second quarter of fiscal 2012 compared to the second quarter of fiscal 2011 was the net result of largely offsetting factors. The primary factor increasing gross margin was decreased intangible amortization due to certain intangibles becoming fully amortized during fiscal 2011 and 2012. Factors largely offsetting this were decreased total revenue and changes in our revenue mix, including lower royalty revenue.

The 30 basis point increase in gross margin percentage in the first six months of fiscal 2012 compared to the first six months of fiscal 2011 was also the net result of largely offsetting factors. The primary factor increasing gross margin percentage for the first six months of fiscal 2012 was decreased intangible amortization expense from certain intangibles becoming fully amortized. This was largely offset by decreased OEM deduplication software revenue as noted earlier and lower royalty revenue in the first six months of fiscal 2012 compared to the first six months of fiscal 2011.

We had an increased percentage of products sold through our branded channels compared to the second quarter and first six months of fiscal 2011. Branded sales comprised 82% and 81% of non-royalty revenue for the second quarter and first six months of fiscal 2012, respectively, compared to 80% and 76% for the second quarter and first six months of fiscal 2011, respectively. Sales of branded products typically generate higher gross margins than sales to our OEM customers; however, OEM deduplication software revenue provides one of our highest product margins.

For the third quarter of fiscal 2012, we expect gross margin to be slightly higher than the second quarter of fiscal 2012 primarily due to changes in the revenue mix and our expectation of increased revenue compared to the second quarter of fiscal 2012

Product Margin

Product gross margin dollars increased $3.6 million, or 9%, on a product revenue increase of 2% compared to the second quarter of fiscal 2011 and our product gross margin rate increased 220 basis points primarily due to decreased intangible amortization and changes in our product revenue mix. We have emphasized sales growth of our disk systems and software solutions which increased to 19% of revenue in second quarter of fiscal 2012 compared to 16% of revenue in the prior year period.

For the first six months of fiscal 2012, product gross margin dollars decreased slightly while the product gross margin rate increased 30 basis points, primarily due to the same factors as total gross margin. Decreased intangible amortization for the first six months of fiscal 2012 was mostly offset by a decrease in high margin OEM deduplication software revenue compared to the first six months of fiscal 2011.

Service Margin

Service gross margin dollars increased slightly and service gross margin percentage increased 270 basis points despite a decrease in service revenue of $1.8 million in the second quarter of fiscal 2012 compared to the second quarter of fiscal 2011. These increases were primarily due to reduced costs for external service providers as a result of bringing repair of certain product lines in-house that previously were repaired by external service providers and negotiating lower rates on the renewals of contracts with certain service providers.

For the first six months of fiscal 2012, service gross margin dollars increased $1.4 million, or 5%, and service gross margin percentage increased 390 basis points despite a decrease in service revenue of $3.8 million. These increases were primarily due to reduced costs from lower inventory allowance expense. We had higher inventory allowance expense in the first six months of fiscal 2011 due to end of service life plans for several products. In addition, we had a decrease in external service provider expense compared to the first six months of fiscal 2011 and a change in the mix of services for OEM repairs and for our branded products under contract. External service provider expense decreased due to a combination of bringing repair of certain product lines in-house and negotiating lower rates on the renewals of contracts with certain service providers. Our service activities continue to reflect a larger proportion of branded products under contract, which have relatively higher margins than margins for OEM repair services.

The increase in sales and marketing expense for the second quarter and first six months of fiscal 2012 was largely due to a $2.2 million and $2.9 million increase, respectively, in compensation and benefits from growing our branded sales force and as a result of higher commissionable revenue. Partially offsetting these increases were decreased marketing expenses of $0.3 million and $0.6 million in the second quarter and first six months of fiscal 2012, respectively. We had higher marketing expense in the prior year periods from efforts to expand our position with existing and new channel partners.

The increase in restructuring charges for the second quarter of fiscal 2012 compared to the second quarter of fiscal 2011 was primarily due to increased severance charges for eliminating certain positions worldwide. In addition, in the second quarter of fiscal 2012 we incurred facility restructuring charges for a facility vacated in India. The increase in restructuring charges for the first six months of fiscal 2012 was primarily due to facility restructuring charges for the facility vacated in India compared to benefits in the first six months of fiscal 2011 from negotiated lease settlements for amounts lower than the outstanding lease contracts. This increase in restructuring expense was partially offset by the restructuring benefit related to cost of revenue in the first six months of fiscal 2012 due to actual payments lower than estimated on a supplier relationship exited in fiscal 2011. For additional information, refer to Note 8: “Restructuring Charges.” Until we achieve sustained profitability, we may incur additional charges in the future related to further cost reduction steps.

Interest expense decreased $3.1 million and $6.5 million in the second quarter and first six months of fiscal 2012, respectively, primarily due to refinancing higher rate subordinated term debt with convertible subordinated debt in fiscal 2011 and to a lesser extent from principal payments in the prior fiscal year reducing the outstanding balance of our senior term debt. Interest expense includes the amortization of debt issuance costs for our debt facilities.

The income tax provision for the second quarter and first six months of fiscal 2012 and 2011 reflects expenses for foreign income taxes and state taxes. We have provided a full valuation allowance against our U.S. net deferred tax assets due to our history of net losses, difficulty in predicting future results and our conclusion that we cannot rely on projections of future taxable income to realize the deferred tax assets.

Significant management judgment is required in determining our deferred tax assets and liabilities and valuation allowances for purposes of assessing our ability to realize any future benefit from our net deferred tax assets. We intend to maintain this valuation allowance until sufficient positive evidence exists to support a reversal or decrease in this allowance. Future income tax expense will be reduced to the extent that we have sufficient positive evidence to support a reversal of, or decrease in, our valuation allowance.

The decrease in intangible expense in the second quarter and first six months of fiscal 2012 compared to the second quarter and first six months of fiscal 2011 was primarily due to certain intangibles becoming fully amortized during fiscal 2011 as well as in the second quarter of fiscal 2012. For further information regarding amortizable intangible assets, refer to Note 6: “Intangible Assets and Goodwill.”

The increase in share-based compensation for the second quarter and first six months of fiscal 2012 compared to the second quarter and first six months of fiscal 2011 was primarily due to an increase in restricted stock units granted in the second quarter of fiscal 2012, largely due to merit increases for our workforce.

LIQUIDITY AND CAPITAL RESOURCES

Following is a summary of cash flows from operating, investing and financing activities (in thousands):

	Six Months Ended

Net income (loss)	$	(1,665	)	$	329

Net cash provided by operating activities		17,006			10,489
Net cash used in investing activities		(15,433	)		(7,513	)
Net cash used in financing activities		(31,090	)		(21,751	)

Six Months Ended September 30, 2011

The $18.7 million difference between reported net loss and cash provided by operating activities during the six months ended September 30, 2011 was primarily due to $28.4 million in non-cash items, the largest of which were amortization, depreciation, share-based compensation and service parts lower of cost or market adjustment. In addition, we had a $6.3 million decrease in accounts receivable primarily due to the timing of billings. These were partially offset by cash uses from a $6.0 million increase in manufacturing inventories, a $5.6 million decrease in deferred revenue and a $4.5 million decrease in accrued compensation. The increase in manufacturing inventories was the net result of lower inventory allowances, increased finished goods and decreased raw materials. The decrease in deferred revenue was largely due to a typical seasonal decline in service contract volumes. The majority of our service contracts renew in our third and fourth fiscal quarters. Accrued compensation decreased primarily due to the timing of payroll payments.

Cash used in investing activities reflects $8.2 million of cash paid, net of cash acquired, for our acquisition of Pancetera and $6.0 million of equipment purchases during the first six months of fiscal 2012. Equipment purchases were primarily for engineering equipment and testing hardware to support product development activities.

Cash used in financing activities during the first six months of fiscal 2012 was primarily due to $35.5 million of principal payments on the senior term debt, partially offset by $7.0 million in proceeds received from the exercise of stock options and issuance of shares under the employee stock purchase plan.

Six Months Ended September 30, 2010

The $10.2 million difference between reported net income and cash provided by operating activities during the six months ended September 30, 2010 was primarily due to $35.6 million in non-cash items, the largest of which were amortization, depreciation, service parts lower of cost or market adjustment and share-based compensation. This was partially offset by an $18.1 million decrease in deferred revenue, a $3.6 million decrease in accounts payable and a $3.2 million decrease in accrued compensation. The decrease in deferred revenue was primarily due to the final utilization of an OEM deduplication software prepayment and to a lesser extent, a typical seasonal decline in service contract volumes. The decrease in accounts payable was primarily due to timing of vendor payments, and the decrease in accrued compensation was primarily due to the timing of payroll payments.

Cash used in investing activities reflects $7.7 million of equipment purchases during the six months ended September 30, 2010. Equipment purchases were primarily for engineering and IT software and engineering test equipment to support product development activities.

Cash used in financing activities during the first six months of fiscal 2011 was primarily due to repaying the outstanding $22.1 million of our 4.375% convertible subordinated notes at maturity.

Capital Resources and Financial Condition

We have made progress in increasing operating income in recent periods, and we continue to focus on improving our operating performance, including increasing revenue in higher margin areas of the business and continuing to improve margins in an effort to return to consistent profitability and to generate positive cash flows from operating activities. We believe that our existing cash and capital resources will be sufficient to meet all currently planned expenditures, debt repayments, contractual obligations and sustain operations for at least the next 12 months. This belief is dependent upon our ability to achieve revenue and gross margin projections and to continue to control operating expenses in order to provide positive cash flow from operating activities. Should any of the above assumptions prove incorrect, either in combination or individually, it would likely have a material negative effect on our cash balances and capital resources.

The following is a description of our existing capital resources including outstanding balances, funds available to borrow, and primary repayment terms including interest rates.

Under the Credit Suisse credit agreement (“CS credit agreement”), we have the ability to borrow up to $50.0 million under a senior secured revolving credit facility which expires July 12, 2012. As of September 30, 2011, we have letters of credit totaling $1.1 million reducing the amounts available to borrow on this revolver to $48.9 million. Quarterly, we are required to pay a 0.5% commitment fee on undrawn amounts under the revolving credit facility.

Our outstanding term debt under the CS credit agreement was $68.8 million at September 30, 2011. This loan matures on July 12, 2014 and has a variable interest rate. The interest rate on the term loan was 3.74% at September 30, 2011. We are required to make quarterly interest and principal payments on the term loan. In addition, on an annual basis, we are required to perform a calculation of excess cash flow which may require an additional payment of the principal amount in certain circumstances. The annual calculations of excess cash flow have not required additional payments. There is a blanket lien on all of our assets under the CS credit agreement in addition to certain financial and reporting covenants. As of September 30, 2011, we were in compliance with all debt covenants.

We have $135 million aggregate principal amount outstanding of 3.50% convertible subordinated notes due November 15, 2015. Semi-annual interest payments are required on these notes.

Generation of positive cash flow from operating activities has historically been and will continue to be an important source of our cash to fund operating needs and meet our current and long-term obligations. We cannot provide assurance that the actions we have taken in the past or any actions we may take in the future to improve our operating results will ensure a consistent, sustainable and sufficient level of net income and positive cash flow from operating activities to fund, sustain or grow our businesses. Certain events that are beyond our control, including prevailing economic, competitive and industry conditions, as well as various legal and other disputes, may prevent us from achieving these financial objectives. Any inability to achieve consistent and sustainable net income and cash flow could result in:

(i)		Restrictions on our ability to manage or fund our existing operations, which could result in a material and adverse effect on our future results of operations and financial condition.

(ii)		Unwillingness on the part of the group of lenders that provide our CS credit agreement to do any of the following:

		Provide a waiver or amendment for any covenant violations we may experience in future periods, thereby triggering a default under, or termination of, the revolving credit line and term loan, or Approve any other amendments to the CS credit agreement we may seek to obtain in the future.
		Any lack of renewal, waiver, or amendment, if needed, could result in the revolving credit line and CS term loan becoming unavailable to us and any amounts outstanding becoming immediately due and payable. In the case of our borrowings at September 30, 2011, this would mean $68.8 million could become immediately payable.

(iii)		Further impairment of our financial flexibility, which could require us to raise additional funding in the capital markets sooner than we otherwise would, and on terms less favorable to us, if available at all.

Any of the above mentioned items, individually or in combination, could have a material and adverse effect on our results of operations, available cash and cash flows, financial condition, access to capital and liquidity.

CRITICAL ACCOUNTING ESTIMATES AND POLICIES

Our discussion and analysis of the financial condition and results of operations is based on the accompanying unaudited Condensed Consolidated Financial Statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of these statements requires us to make significant estimates and judgments about future uncertainties that affect reported assets, liabilities, revenues and expenses and related disclosures. We base our estimates on historical experience and on various other assumptions believed to be reasonable under the circumstances. In the event that estimates or assumptions prove to be different from actual results, adjustments are made in subsequent periods to reflect more current information. The accounting estimates requiring our most difficult, subjective or complex judgments because these matters are inherently uncertain are unchanged from March 31, 2011, except for the estimated fair value of assets acquired in a business combination described below. These critical accounting estimates and policies have been disclosed in our Annual Report on Form 10-K for the year ended March 31, 2011 filed with the Securities and Exchange Commission on June 14, 2011.

Fair Value of Assets Acquired in a Business Combination

Application of the various accounting principles related to the fair value measurement of certain assets acquired in a business combination are critical accounting estimates because there are matters that are inherently uncertain when the estimate is made, different estimates reasonably could have been used and changes in the estimate that are reasonably possible could materially impact the resulting valuation and the financial statements. Judgments were required to determine fair values of amortizable intangible assets, in-process research and development and the resulting amount of goodwill. Significant estimates and assumptions included:

Planned product roadmaps, including the primary feature sets of new products;
Expected efforts and associated costs required to integrate technologies acquired into new products;
Assessed importance of in-process research and development to our overall development plan;
Estimated values and rates of a market participant;
Estimated future cash flows of current and future products; and
Estimated discount rate applied to future cash flows.

In addition, the estimated future life of purchased technology intangibles impacts future financial statements. We believe the assumptions and estimates used and the resulting balances are reasonable; however, actual results may differ from these estimates under different assumptions or conditions.

RECENT ACCOUNTING PRONOUNCEMENTS

In the first quarter of fiscal 2012, we adopted the goodwill impairment guidance for reporting units with zero or negative carrying amounts and adopted the guidance for disclosure of supplementary pro forma information for business combinations. The adoption of these standards did not have an impact on our financial position or results of operations, other than additional disclosures. For information regarding our assessment of other recent accounting pronouncements, refer to Note 2: “Significant Accounting Policies; New Accounting Standards.”

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Changes in interest rates affect interest income earned on our cash equivalents. In addition, changes in interest rates affect interest expense on our borrowings under the CS credit agreement. Our outstanding convertible subordinated notes have a fixed interest rate, thus a hypothetical 100 basis point increase in interest rates would not impact interest expense on these borrowings.

Our cash equivalents consisted solely of money market funds during the six months ended September 30, 2011. During the first six months of fiscal 2012, interest rates on these funds were under 1.0% and we earned negligible amounts in interest income.

Interest accrues on our CS term loan at our option, based on either, a prime rate plus a margin of 2.5%, or a LIBOR rate plus a margin of 3.5%. A hypothetical 100 basis point increase in interest rates would increase interest expense $0.5 million.

ITEM 4. CONTROLS AND PROCEDURES

(a)		Evaluation of disclosure controls and procedures. Our management evaluated, with the participation of our Chief Executive Officer and our Chief Financial Officer, the effectiveness of our disclosure controls and procedures as of the end of the period covered by this Quarterly Report on Form 10-Q. Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures are effective.

(b)		Changes in internal control over financial reporting. There was no change in our internal control over financial reporting that occurred during the fiscal quarter covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

YOU SHOULD CAREFULLY CONSIDER THE RISKS DESCRIBED BELOW, TOGETHER WITH ALL OF THE OTHER INFORMATION INCLUDED IN THIS QUARTERLY REPORT ON FORM 10-Q. THE RISKS AND UNCERTAINTIES DESCRIBED BELOW ARE NOT THE ONLY ONES FACING QUANTUM. ADDITIONAL RISKS AND UNCERTAINTIES NOT PRESENTLY KNOWN TO US OR THAT ARE CURRENTLY DEEMED IMMATERIAL MAY ALSO IMPAIR OUR BUSINESS AND OPERATIONS. THIS QUARTERLY REPORT ON FORM 10-Q CONTAINS “FORWARD-LOOKING” STATEMENTS THAT INVOLVE RISKS AND UNCERTAINTIES. PLEASE SEE “MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS” FOR ADDITIONAL DISCUSSION OF THESE FORWARD-LOOKING STATEMENTS.

We rely on indirect sales channels to market and sell our branded products. Therefore, the loss of or deterioration in our relationship with one or more of our resellers or distributors, or our inability to establish new indirect sales channels to drive growth of our branded revenue, especially for disk systems and software solutions, could negatively affect our operating results.

We sell the majority of our branded products to value-added resellers, or VARs, and to direct marketing resellers such as CDW Corporation, who in turn sell our products to end users, and to distributors such as Avnet, Inc., Ingram Micro, Inc. and others. The success of these sales channels is hard to predict, particularly over time, and we have no purchase commitments or long-term orders from them that assure us of any baseline sales through these channels. Several of our resellers carry competing product lines that they may promote over our products. A reseller might not continue to purchase our products or market them effectively, and each reseller determines the type and amount of our products that it will purchase from us and the pricing of the products that it sells to end user customers. Establishing new indirect sales channels is an important part of our strategy to drive growth of our branded revenue.

Certain of our contracts with our distributors contain “most favored nation” pricing provisions mandating that we offer our products to these customers at the lowest price offered to other similarly situated customers. In addition, sales of our enterprise products, and the revenue associated with the on-site service of those products, are somewhat concentrated in specific customers, including government agencies and government-related companies. Our operating results could be adversely affected by any number of factors including:

Our operating results depend on a limited number of products and on new product introductions, which may not be successful, in which case our business, financial condition and operating results may be materially and adversely affected.

A limited number of products comprise a significant majority of our sales, and due to increasingly rapid technological change in the industry, our future operating results depend on our ability to develop and successfully introduce new products. To compete effectively, we must continually improve existing products and introduce new ones, such as the DXi-Series, Scalar i6000 and the Scalar i40 and i80 product offerings as well as next generation software such as DXi2.0 and StorNext 4.0. We have devoted and expect to continue to devote considerable management and financial resources to these efforts. We cannot provide assurance that:

If we are not successful in timely completion of our new product qualifications and then ramping sales to our key customers, our revenue and results of operations could be adversely impacted. In addition, if the quality of our products is not acceptable to our customers, this could result in customer dissatisfaction, lost revenue and increased warranty and repair costs.

Competition has increased and evolved, and may increasingly intensify, in the data protection market as a result of competitors introducing products based on new technology standards, and merger and acquisition activity, which could materially and adversely affect our business, financial condition and results of operations.

Our disk systems compete with product offerings of EMC Corporation (“EMC”), Hewlett-Packard Company (“HP”), International Business Machines Corporation (“IBM”) and NetApp, Inc. (“NetApp”). A number of our competitors also license technology from competing companies such as FalconStor Software, Inc. and Sepaton, Inc. These competitors are aggressively trying to advance and develop new technologies and products to compete against our technologies and products, and we face the risk that customers could choose competitor products over ours due to these features and technologies. Competition in the disk systems market, including deduplication and replication technologies, is characterized by technological innovation and advancement. As a result of competition and new technology standards, our sales or gross margins for disk systems could decline, which could materially and adversely affect our business, financial condition and results of operations.

Our vmPRO appliances and software for virtual environments primarily compete with offerings from IBM, PhD Virtual Technologies, Quest Software, Inc. and Veeam Software. In addition, there are startup companies and companies expanding into the virtual environment data protection market. These competitors are aggressively trying to advance and develop new technologies and products, and we face the risk that customers could choose competitor products over ours due to these features and technologies. Competition in the data protection market for virtual environments is characterized by technological innovation and advancement. As a result of competition and new technology standards, our sales or gross margins for virtualization software and appliances could decline, which could materially and adversely affect our business, financial condition and results of operations.

Our tape automation products primarily compete with product offerings of BDT Products Inc., Dell, Inc. (“Dell”), HP, IBM, and Oracle Corporation (“Oracle”). Increased competition has resulted in decreased prices for tape automation products and product offerings that incorporate new features and technologies. Pricing pressure is more pronounced in the tape automation market for entry-level products and least pronounced for enterprise products. Similar to our competitors, our products may be priced lower and often incorporate new and/or different features and technologies than prior years. We face risks that customers could choose competitor products over ours due to these features and technologies or due to pricing differences. We have managed pricing pressure by reducing production costs and/or adding features to increase value to maintain a certain level of gross margin for our tape automation systems. If competition further intensifies, or if there is additional industry consolidation, our sales and gross margins for tape automation systems could decline, which could materially and adversely affect our business, financial condition and results of operations.

Our devices, which include tape drives and removable hard drives, compete with companies that develop, manufacture, market and sell similar products. The principal competitors for our devices include HP and IBM. Competition and industry consolidation has resulted in decreased prices and increasingly commoditized products. Our response has been to manage our device business at the material margin level and we have chosen not to compete for sales in intense price-based situations or if we would be unable to maintain a certain gross margin level. Our focus has shifted to higher margin opportunities in other product lines. Although revenue from devices has decreased in recent years, our material margins have remained relatively stable over this period. We have exited certain portions of the device market and have anticipated decreased sales of devices. We face risk of reduced shipments of our devices beyond our plans, and could have reduced margins on these products, which could materially and adversely impact our business, financial condition and results of operations.

Additionally, the competitive landscape could change due to merger and acquisition activity in the data protection market, such as consolidations in prior years resulting from the purchase of Sun Microsystems, Inc. by Oracle and the acquisition of Data Domain, Inc. (“Data Domain”) by EMC. Transactions such as these may impact us in a number of ways. For instance, they could result in:

These transactions also create uncertainty and disruption in the market, given that it is often unknown whether a pending transaction will be completed, the timing of such a transaction, and its degree of impact. Given these factors and others, such merger and acquisition activity may materially and adversely impact our business, financial condition and results of operations.

Competition has increased and evolved, and may increasingly intensify, in the big data and archive market as a result of competitors introducing products based on new technology standards, and merger and acquisition activity, which could materially and adversely affect our business, financial condition and results of operations.

Our StorNext software and StorNext appliances face competition from a number of companies, including Front Porch Digital, EMC and IBM. Competition in the big data and archive market is characterized by technological innovation and advancement, including performance and scale features, and our competitors are aggressively trying to advance and develop new technologies and solutions. We face the risk that customers could choose competitor solutions over ours due to these features and technologies. As a result of competition and new technology standards, our sales from software solutions and appliances could decline, which could materially and adversely affect our business, financial condition and results of operations.

Additionally, the competitive landscape could change due to merger and acquisition activity, such as the acquisition of Isilon Systems, Inc. by EMC. Transactions such as these may impact us in a number of ways. For instance, they could result in:

Our royalties, branded software and OEM deduplication software revenues are relatively profitable and can significantly impact total company profitability. A significant decline in royalty, branded software or OEM deduplication software revenues could materially and adversely affect our business, financial condition and operating results.

We receive royalty revenue based on tape media cartridges sold by Fujifilm Corporation, Imation Corporation, Hitachi Ltd., Maxell Limited, Sony Corporation and TDK Corporation. Under our license agreements with these companies, each of the licensees determines the pricing and number of units of tape media cartridges that it sells. Our royalty revenue varies depending on the level of sales of the various media cartridge offerings sold by the licensees and other factors, including:

Our media royalties depend on royalty rates and the quantity of media consumed in the market. We do not control licensee sales of these tape media cartridges. Reduced royalty rates, or a reduced installed device base using tape media cartridges, would result in further reductions in our royalty revenue and could reduce gross margins. This could materially and adversely affect our business, financial condition and results of operations.

Our branded software revenues are also dependent on many factors, including the success of competitive offerings, our ability to execute on our product roadmap and our effectiveness at marketing and selling our branded software solutions directly or through our channel partners.

Our OEM deduplication software revenues also depend on many factors, including the success of competitive offerings, our ability to execute on our product roadmap with our OEM deduplication software partners, the effort of our OEM deduplication software partners in marketing and selling the resulting products, the market acceptance of the resulting products and changes in the competitive landscape such as that which occurred with EMC’s purchase of Data Domain. Our relationship with EMC changed from partner to competitor in deduplication as a result of their acquisition of Data Domain. Following this acquisition, except for the first quarter of fiscal 2011 when significant revenue was recognized in accordance with contractual requirements, our OEM deduplication software revenue has significantly declined, which has negatively impacted our results.

We derive the majority of our revenue from products incorporating tape technology. If competition from new or alternative storage technologies continues or increases, our business, financial condition and operating results could be materially and adversely affected.

We derive the majority of our revenue from products that incorporate some form of tape technology and we expect to continue to derive a majority of our revenue from these products in the next several years. As a result, our future operating results depend in part on continued market acceptance and use of products employing tape technology. Our tape products are increasingly challenged by products using alternative technologies, such as VTL, standard disk arrays and NAS. If disk products gain comparable or superior market acceptance, or their purchase prices decline, the competition resulting from these products would increase as our tape customers migrate toward them.

We are addressing this risk through our own targeted investment in disk systems and other alternative technologies; however, these markets are characterized by rapid innovation, evolving customer demands and strong competition, including competition with several companies who are also significant customers. If we are not successful in our efforts, our business, financial condition and operating results could be materially and adversely affected.

A large percentage of our sales come from a few customers, some of which are also competitors, and these customers generally have no minimum or long-term purchase commitments. The loss of, or a significant reduction in demand from, one or more key customers could materially and adversely affect our business, financial condition and operating results.

Our sales have been and continue to be concentrated among a few customers. For example, sales to our top five customers in fiscal 2011 represented 33% of total revenue. This sales concentration does not include revenues from sales of our media that our licensees sold to these customers, for which we earn royalty revenue. Furthermore, customers are not obligated to purchase any minimum product volume and our relationships with customers are terminable at will. As an example, in fiscal 2011, sales to Dell contributed approximately 10% of our revenue, a decline from prior years. If we experience further declines in revenue from Dell or any of our other large customers, we could be materially and adversely affected. In addition, certain of our large customers are also our competitors, and such customers could decide to reduce or terminate their purchases of our products for competitive reasons.

Many of our tape and disk products are primarily incorporated into larger storage systems or solutions that are marketed and sold to end users by our large OEM customers as well as our value added resellers, channel partners and other distributors. Because of this, we have limited market access to these end users, limiting our ability to reach and influence their purchasing decisions. These market conditions further our reliance on these OEM and other large customers such as distributors and VARs. Thus if they were to significantly reduce, cancel or delay their orders with us, our results of operations could be materially and adversely affected.

If our products fail to meet our or our customers’ specifications for quality and reliability, our results of operations may be adversely impacted and our competitive position may suffer.

Although we place great emphasis on product quality, we may from time to time experience problems with the performance of our products, which could result in one or more of the following:

These factors could cause our business, financial condition and results of operations to be materially and adversely affected.

Our capital structure includes debt, which has corresponding debt service obligations and our Credit Suisse senior credit agreement contains various operating and financial covenants that limit our discretion in the operation of our business. Unless we are able to generate sufficient cash flows from operations to meet these debt obligations, our business, financial condition and operating results could be materially and adversely affected.

Our level of indebtedness presents risks to investors, both in terms of the constraints that it places on our ability to operate our business and because of the possibility that we may not generate sufficient cash to pay the principal and interest on our indebtedness as it becomes due.

Potential consequences of having debt include:

Our ability to meet our debt service obligations and fund our working capital, capital expenditures, acquisitions, research and development and other general corporate needs depends upon our ability to generate sufficient cash flow from operations. We cannot provide assurance that we will generate sufficient cash flow from operations to service these debt obligations, or that future borrowings or equity financing will be available to us. Such a failure to repay our debt obligations when due would result in default under our loan agreements. Any such inability to meet our debt obligations could therefore have a material and adverse effect on our business, financial condition and results of operations.

Our Credit Suisse credit agreement (“CS credit agreement”) contains numerous restrictive covenants that require us to comply with and maintain certain financial tests and ratios, as well as restrict our ability to:

Our ability to comply with covenants contained in this credit agreement may be affected by events beyond our control, including prevailing economic, financial and industry conditions. In prior years, we violated certain financial covenants under a prior credit agreement and received waivers or amendments for such violations. Even if we are able to comply with all covenants, the restrictions on our ability to operate our business could harm our business by, among other things, limiting our ability to take advantage of financings, mergers, acquisitions and other corporate opportunities.

Our CS credit agreement is collateralized by a pledge of all of our assets. If we were to default and were unable to obtain a waiver for such a default, the lenders would have a right to foreclose on our assets in order to satisfy our obligations under the CS credit agreement. Any such action on the part of the lenders against us could have a materially adverse impact on our business, financial condition and results of operations.

We have taken considerable steps towards reducing our cost structure and may take further cost reduction actions. The steps we have taken and may take in the future may not reduce our cost structure to a level appropriate in relation to our future sales and therefore, these anticipated cost reductions may be insufficient to result in consistent profitability.

In the last several years, we have recorded significant restructuring charges and made cash payments in order to reduce our cost of sales and operating expenses to rationalize our operations following past acquisitions, to respond to adverse economic and industry conditions and from strategic management decisions. We may take future steps to further reduce our operating costs, including future cost reduction steps or restructurings in response to strategic decisions, adverse changes in our business or industry or future acquisitions. We may be unable to reduce our cost of sales and operating expenses at a rate and to a level appropriate in relation to our future sales, which may adversely affect our business, financial condition and operating results.

Our inability to attract and retain skilled employees could adversely impact our business.

We may be subject to increased turnover in our employee base or the inability to fill open headcount requisitions due to competition, concerns about our operational performance or other factors. In addition, we may rely on the performance of employees whose skill sets are not sufficiently developed enough to completely realize the expected fulfillment of their job responsibilities. Either of these situations could impair or delay our ability to realize operational and strategic objectives and cause increased expenses and lost sales opportunities.

Economic or other business factors may lead us to further write down the carrying amount of our goodwill or long-lived assets, such as the $339 million goodwill impairment charge taken in fiscal 2009, which could have a material and adverse effect on our results of operations.

We evaluate our goodwill for impairment annually during the fourth quarter of our fiscal year, or more frequently when indicators of impairment are present. Long-lived assets are reviewed for impairment whenever events or circumstances indicate impairment might exist. We continue to monitor relevant market and economic conditions, including the price of our stock, and perform appropriate impairment reviews when conditions deteriorate such that we believe the value of our goodwill could be further impaired or an impairment exists in our long-lived assets. It is possible that conditions could deteriorate due to economic or other factors that affect our business, resulting in the need to write down the carrying amount of our goodwill or long-lived assets to fair value at the time of such assessment. As a result, our operating results could be materially and adversely affected.

Third party intellectual property infringement claims could result in substantial liability and significant costs, and, as a result, our business, financial condition and operating results may be materially and adversely affected.

From time to time, third parties allege our infringement of and need for a license under their patented or other proprietary technology. While we currently believe the amount of ultimate liability, if any, with respect to any such actions will not materially affect our financial position, results of operations or liquidity, the ultimate outcome of any license discussion or litigation is uncertain. Adverse resolution of any third party infringement claim could subject us to substantial liabilities and require us to refrain from manufacturing and selling certain products. In addition, the costs incurred in intellectual property litigation can be substantial, regardless of the outcome. As a result, our business, financial condition and operating results could be materially and adversely affected.

In addition, certain products or technologies acquired or developed by us may include “open source” software. Open source software is typically licensed for use at no initial charge. Certain open source software licenses, however, require users of the open source software to license to others any software that is based on, incorporates or interacts with, the open source software under the terms of the open source license. Although we endeavor to comply fully with such requirements, third parties could claim that we are required to license larger portions of our software than we believe we are required to license under open source software licenses. If such claims were successful, they could adversely impact our competitive position and financial results by providing our competitors with access to sensitive information that may help them develop competitive products. In addition, our use of open source software may harm our business and subject us to intellectual property claims, litigation or proceedings in the future because:

As a result of our global manufacturing and sales operations, we are subject to a variety of risks that are unique to businesses with international operations of a similar scope, any of which could, individually or in the aggregate have a material adverse effect on our business.

A significant portion of our manufacturing and sales operations and supply chain occurs in countries other than the U.S. We also have sales outside the U.S. We utilize contract manufacturers to produce certain of our products and have suppliers for various components, several of which have operations located in foreign countries including China, Hungary, Japan, Malaysia, Mexico, Singapore and Taiwan. Because of these operations, we are subject to a number of risks including:

Any or all of these risks could have a material adverse effect on our business.

Our quarterly operating results could fluctuate significantly, and past quarterly operating results should not be used to predict future performance.

Our quarterly operating results have fluctuated significantly in the past and could fluctuate significantly in the future. As a result, our quarterly operating results should not be used to predict future performance. Quarterly operating results could be materially and adversely affected by a number of factors, including, but not limited to:

If we fail to meet our projected quarterly results, our business, financial condition and results of operations may be materially and adversely affected.

If we fail to protect our intellectual property or if others use our proprietary technology without authorization, our competitive position may suffer.

Our future success and ability to compete depends in part on our proprietary technology. We rely on a combination of copyright, patent, trademark, and trade secrets laws and nondisclosure agreements to establish and protect our proprietary technology. As of March 31, 2011, we held 517 U.S. patents and had 86 U.S. patent applications pending. However, we cannot provide assurance that patents will be issued with respect to pending or future patent applications that we have filed or plan to file or that our patents will be upheld as valid or will prevent the development of competitive products or that any actions we have taken will adequately protect our intellectual property rights. We generally enter into confidentiality agreements with our employees, consultants, customers, potential customers and others as required, in which we strictly limit access to, and distribution of, our software, and further limit the disclosure and use of our proprietary information.

Despite our efforts to protect our proprietary rights, unauthorized parties may attempt to copy or otherwise obtain or use our products or technology. Enforcing our intellectual property rights can sometimes only be accomplished through the use of litigation, such as in the litigation with Riverbed Technology, Inc. settled in fiscal 2009. Our competitors may also independently develop technologies that are substantially equivalent or superior to our technology. In addition, the laws of some foreign countries do not protect our proprietary rights to the same extent as the laws of the U.S.

Because we may order components from suppliers in advance of receipt of customer orders for our products which include these components, we could face a material inventory risk, which could have a material and adverse effect on our results of operations and cash flows.

Although we use third parties to manufacture certain of our products, we also manufacture products in-house. Managing our in-house manufacturing capabilities presents a number of risks that could materially and adversely affect our financial condition. For instance, as part of our component planning, we place orders with or pay certain suppliers for components in advance of receipt of customer orders. We occasionally enter into negotiated orders with vendors early in the manufacturing process of our products to ensure that we have sufficient components for our products to meet anticipated customer demand. Because the design and manufacturing process for these components can be complicated, it is possible that we could experience a design or manufacturing flaw that could delay or even prevent the production of the components for which we previously committed to pay. We also face the risk of ordering too many components, or conversely, not enough components, since supply orders are generally based on forecasts of customer orders rather than actual customer orders. In addition, in some cases, we make non-cancelable order commitments to our suppliers for work-in-progress, supplier’s finished goods, custom sub-assemblies, discontinued (end-of-life) components and Quantum-unique raw materials that are necessary to meet our lead times for finished goods. If we cannot change or be released from supply orders, we could incur costs from the purchase of unusable components, either due to a delay in the production of the components or other supplies or as a result of inaccurately predicting supply orders in advance of customer orders. These same risks exist with our third party contract manufacturing partners. Our business and operating results could be materially and adversely affected if we incur increased costs, or are unable to fulfill customer orders.

Some of our manufacturing, component production and service repair are outsourced to third party contract manufacturers, component suppliers and service providers. If we cannot obtain products, parts and services from these third parties in a cost effective and timely manner that meets our customers’ expectations, this could materially and adversely impact our business, financial condition and results of operations.

Many aspects of our supply chain and operational results are dependent on the performance of third party business partners. We face a number of risks as a result of these relationships, including, among others:

Any or all of these risks could have a material adverse effect on our business. In the past we have successfully transitioned products or component supply from one supplier to another existing supplier of different products or to our own facilities without significant financial or operational impact, but there is no guarantee of our continued ability to do so.

If we do not successfully manage the changes that we have made and may continue to make to our infrastructure and management, our business could be disrupted, and that could adversely impact our results of operations and financial condition.

Managing change is an important focus for us. In recent years, we have implemented several significant initiatives involving our sales and marketing, engineering and operations organizations, aimed at increasing our efficiency and better aligning these groups with our corporate strategy. In addition, we have reduced headcount to streamline and consolidate our supporting functions as appropriate following past acquisitions and in response to market or competitive conditions. Our inability to successfully manage the changes that we implement, and detect and address issues as they arise could disrupt our business and adversely impact our results of operations and financial condition.

We continue to face risks related to the slow economic recovery.

The economic crisis in the U.S. and global financial markets had a material and adverse impact on our business and our financial condition, including reduced demand for our products and concerns about our ability to access capital markets to refinance certain debt. The initial impact of this economic crisis was reflected in our results for the second quarter of fiscal 2009. We continue to face risks related to the slow economic recovery and concerns of a return to a recession, including the impact to our results in the first half of fiscal 2011 from economic conditions in Europe. In addition, concerns about the potential default of various national bonds and debt backed by individual countries as well the politics impacting these, could negatively impact the U.S. and global economies and adversely affect our financial results. Uncertainty about economic conditions poses a risk as businesses may further reduce or postpone spending in response to reduced budgets, tight credit, negative financial news and declines in income or asset values which could adversely affect our business, financial condition and results of operations. In addition, our ability to access capital markets may be restricted which could have an impact on our ability to react to changing economic and business conditions and could also adversely affect our results of operations and financial condition.

Our stock price could become more volatile if certain institutional investors were to increase or decrease the number of shares they own. In addition, there are other factors and events that could affect the trading prices of our common stock.

Five institutional investors owned approximately 37% of our common stock as of March 31, 2011. If any or all of these investors were to decide to purchase significant additional shares or to sell significant amounts or all of the common shares they currently own, that may cause our stock price to be more volatile. For example, there have been instances in the past where a shareholder with a significant equity position began to sell shares, putting downward pressure on our stock price for the duration of their selling activity. In these situations, selling pressure outweighed buying demand and our stock price declined. This situation has occurred due to our stock price falling below institutional investors’ price thresholds and our volatility increasing beyond investors’ volatility parameters causing even greater sell pressure. The opposite has also occurred whereby a shareholder purchases a significant equity position, creating demand for our common stock and an increased stock price.
