OVERVIEW

Quantum Corporation ("Quantum", the "Company", "us" or "we") founded in 1980, is a leading global storage company specializing in backup, recovery and archive solutions. Combining focused expertise, customer-driven innovation and platform independence, we provide a comprehensive, integrated range of disk, tape and software solutions supported by our sales and service organization. We work closely with a broad network of value-added resellers ("VARs"), original equipment manufacturers ("OEMs") and other suppliers to meet customers' evolving data protection needs. Our stock is traded on the New York Stock Exchange under the symbol "QTM."

We are dedicated to backup, recovery and archive solutions and strive to provide focused expertise, customer-driven innovation and platform independence that competitors cannot match. We believe our combination of expertise, innovation and platform independence allows us to solve customers' data protection and retention issues more easily, effectively and securely. In addition, we have the global scale and scope to support our worldwide customer base.

We offer a comprehensive range of solutions in the data storage market providing performance and value to organizations of all sizes. We have a broad portfolio of disk-based backup solutions, tape libraries, autoloaders and tape drives and media. Our data management software provides technology for shared workflow applications and multi-tiered archiving in high-performance, large-scale storage environments. We also feature software options with products that provide disk and tape integration capabilities with our core de-duplication and replication technologies. In addition, our service plan includes a broad range of coverage options to provide the level of support for the widest possible range of information technology ("IT") environments, with service available in more than 100 countries.

We earn our revenue from the sale of products, systems and services through an array of channel partners to reach end user customers, which range in size from small businesses and satellite offices to government agencies and large, multinational corporations. Our products are sold under the Quantum brand name and under the names of various OEM customers. We face a variety of challenges and opportunities in responding to the competitive dynamics of the technology market which is characterized by rapid change, evolving customer demands and intense competition, including competition with several companies that are also significant customers.

The worldwide economic climate deteriorated significantly during the second quarter of fiscal 2009, creating challenges for many companies. The global financial crisis has impacted our business; however, our top priority in fiscal 2009 continues to be growing our branded revenue, particularly our disk-based backup systems and software solutions, in order to improve profitability and increase shareholder value. We continue to believe delivering a better operating model, creating more growth potential and reducing our outstanding debt are also important drivers to improve profitability and increase shareholder value.

Our objectives to achieve these priorities in the second half of fiscal 2009 include our continued focus on growth opportunities by building upon our disk-based backup systems and software solutions; shifting our revenue mix to higher margin areas of our business, especially our branded business; and continued generation of cash flow from operations to allow us to pay down our term debt and reduce our interest costs. In addition, we have reduced investments in declining market segments and will continue our efforts to reduce costs while retaining a solid execution platform.

Our revenue performance for the second quarter of fiscal 2009 was below expectations. We believe we have taken many actions to deliver improved revenue results; however, the global financial crisis impacted our ability to close business at the end of the quarter. We had numerous customers defer purchases that typically would have closed during the quarter. We believe that many of these sales will close in the coming quarters given the strong demand for data de-duplication and replication in the storage market, but there remains a significant risk that demand for backup, storage and archive solutions will soften further as our customers manage their IT investments more carefully. Additionally, we are observing longer sales cycles for many of our products for this same reason.

Despite the revenue decline, we made progress in the second quarter of fiscal 2009 toward achievement of our goals. Although our branded revenue was lower than plan, our gross margins increased due to revenue mix improvements. We settled litigation with Riverbed Technology, Inc. ("Riverbed") and received a one-time payment of $11.0 million which was recorded as royalty revenue. The $11.0 million royalty revenue contributed to improved gross margins and was the primary driver of income from operations.

For the second quarter of fiscal 2009, branded revenue increased to 66% of non-royalty revenue from 63% in the second quarter of fiscal 2008. We continued to demonstrate growth in our higher margin disk-based backup systems and software solutions in the second quarter of fiscal 2009. We generated additional cash flow from operations and repaid $40.0 million of our term debt during the quarter. We had a $5.7 million quarterly operating profit in the second quarter of fiscal 2009 compared to a $6.2 million quarterly operating loss in the first quarter of fiscal 2009. Quarterly operating profits increased $2.4 million from the second quarter of fiscal 2008.

During the second quarter of fiscal 2009, revenue decreased by $33.1 million to $215.4 million from the same quarter last year. The revenue decrease was primarily due to a decrease in product revenue from tape automation systems and to a lesser extent from devices and media products. Partially offsetting these decreases were increased product revenues from disk-based backup systems and software solutions from the newly released DXi7500 and software licensing and distribution with our software partner EMC. Moderating the total revenue decrease was increased royalty revenue due to the Riverbed settlement and increased service revenue.

Although revenue decreased for the quarter, our gross margin percentage increased 700 basis points to 38.5% due to the change in product revenue sales mix and the $11.0 million royalty revenue resulting from the Riverbed settlement. Gross margin also increased because product sales through our branded channels comprised a larger percentage of non-royalty revenue in the second quarter of fiscal 2009 compared to the same quarter of the prior year. Sales of branded products typically generate higher gross margins than sales to our OEM customers. Gross margin was also favorably impacted due to our shift in sales mix toward higher margin disk-based systems and software solutions and from cost reduction measures implemented in prior periods.

Operating expenses increased for the current quarter compared to the same quarter last year primarily due to increased sales and marketing expenses and general and administrative expenses partially offset by decreased research and development costs. Sales and marketing expenses increased in line with our emphasis on growing our branded business while increased legal expenses to protect our intellectual property were the primary driver of increased general and administrative expenses. Research and development costs declined in the quarter primarily due to decreased compensation expenses from headcount reductions implemented in prior periods. Although operating expenses increased, we generated income from operations largely due to increased gross margins.

During the quarter, we repaid $40.0 million of the term loan on our credit facility. Since August 2006, we have repaid approximately 50%, or $246.5 million, of our acquisition-related debt. Interest expense continued to decrease from prior quarters due to the combination of lower interest rates on a lower outstanding debt balance. As of September 30, 2008, our outstanding term debt balance was $250.0 million.

We received notification from the NYSE on October 27, 2008 that we are not in compliance with the NYSE's continued listing standard requiring that stocks trade at a minimum average closing price of $1.00 for thirty consecutive trading days. Under NYSE rules, we must inform the NYSE by November 10, 2008, of our intent to cure the average stock price deficiency, and we intend to do so. Under the NYSE rules, we have until April 27, 2009, to comply with the listing standard. Our stock will continue to be listed on the NYSE during the six-month cure period, subject to compliance with other NYSE continued listing requirements. We expect we will comply with the listing standard by April 27, 2009 either by sufficiently improving our results leading to an increased stock price or through a reverse stock split to cure the deficiency. At our August 19, 2008 annual meeting, our shareholders authorized our Board of Directors to select and file one of several possible amendments to our amended and restated certificate of incorporation which would effect a reverse stock split, pursuant to which any whole number of outstanding shares of our common stock between and including four and twelve would be combined into one share of such stock. The authorization granted our directors the flexibility to decide whether or not a reverse stock split, and at what ratio, would be in the best interests of the Company.

Total revenue decreased in the second quarter and first six months of fiscal 2009 compared to the second quarter and first six months of fiscal 2008 primarily due to lower tape automation systems revenue in North America and Europe and to a lesser extent decreased revenue from devices and non-royalty media. Moderating the total revenue decrease were increases in royalty revenue due to the Riverbed settlement and increased service revenue. We expect total revenue for the second half of fiscal 2009 between $400 million and $450 million, approximating total revenue for the first six months of fiscal 2009. Our fiscal third quarter has been our strongest revenue quarter in past years; however, the risks of lower demand and longer sales cycles due to uncertainty about the economic environment may diminish or eliminate the traditional strength of our fiscal third quarter.

Product Revenue

Our product revenue, which includes sales of our hardware and software products sold through both our Quantum branded and OEM channels, decreased for the second quarter and first six months of fiscal 2009 compared to the same periods of fiscal 2008. Decreased branded product sales comprised slightly more of the product revenue decline in the second quarter of fiscal 2009 than was attributable to decreased sales to our OEM customers. The product revenue decrease for the first six months of fiscal 2009 was primarily due to decreased sales to our OEM customers. Product revenue decreases in the second quarter and first six months of fiscal 2009 were primarily due to decreased revenue from tape automation systems and decreased revenue from devices and media products. These decreases were partially offset by increased sales of disk-based backup systems and software solutions in the second quarter and first six months of fiscal 2009.

                                                                  Three Months Ended

Approximately two-thirds of the tape automation systems revenue decreases for the second quarter and first six months of fiscal 2009 compared to the prior year periods were attributable to reduced sales of OEM products and approximately one-third due to lower branded sales in North America and Europe. We expect increased tape automation systems sales in the future as a result of changes implemented in our branded sales force and our continued focus on selling across our entire portfolio.

Product revenue from devices, which includes tape drives and removable hard drives, and non-royalty media sales declined in the second quarter and first six months of fiscal 2009 compared to the prior year periods primarily due to decreased branded and OEM sales of older device technology that is nearing end of life. Media sales also decreased for the second quarter of fiscal 2009 compared to fiscal 2008. We continue to manage our media business opportunistically to maintain sufficient gross margins from media sales. Due to market pricing for media during the second quarter of fiscal 2009, we chose not to pursue additional media sales. For the first six months of fiscal 2009 compared to the prior year period, the decline in device revenues was partially offset by increased media revenue from media sales during the first quarter of fiscal 2009. We expect further declines in our OEM device revenue in the future resulting from older device technology products nearing end of life and our emphasis on higher margin opportunities.

Revenue increases from disk-based backup systems and software solutions in the second quarter and first six months of fiscal 2009 compared to the same periods of fiscal 2008 were primarily due to the addition of the DXi7500 to our disk-based backup systems portfolio and software license revenue from EMC. These increases were offset in part by declines in sales of our legacy disk-based products in both the second quarter and first six months of fiscal 2009. As noted earlier, we are focused on growing our branded revenue in fiscal 2009, particularly our disk-based backup systems and software revenue. We expect increases in our disk-based backup systems and software solutions revenue in the future as our disk-based backup systems continue to gain traction in the market.

Service Revenue

Service revenue includes revenue from sales of hardware service contracts, product repair, installation and professional services. Sales of hardware service contracts are typically purchased by our customers to extend the warranty, to provide faster service response time, or both. Service revenue increased $2.6 million and $4.7 million compared to the second quarter and first six months of the prior year, respectively, largely due to increased sales of service contracts to customers of our branded products. We expect continued increases in service revenue in the future as our installed base of branded products continues to grow.

Royalty Revenue

In the second quarter of fiscal 2009, we recorded $11.0 million in royalty revenue in connection with a settlement agreement with Riverbed that contains a mutual covenant to not sue related to the parties' data de-duplication patents. The covenant not to sue is similar to a cross-license. This $11.0 million was based on prior sales of the parties' data de-duplication products. See Note 16, "Litigation" for additional information.

Tape media royalties decreased $4.9 million and $7.0 million in the second quarter and first six months of fiscal 2009, respectively, compared to the prior year periods primarily due to lower tape media unit sales sold to licensees. Royalties related to our newer LTO products continue to increase, but at a slower rate than declines in royalties from our maturing DLT products, where we experienced a net reduction in the installed base of DLTtape ® drives.

We expect LTO royalties will continue to increase as the installed base grows and DLT royalties will further decline over time as its installed base continues to decrease. For the second half of fiscal 2009, we continue to expect moderately lower tape media royalties compared to the first six months of fiscal 2009.

Approximately half of the 700 basis point increase in gross margin percentage during the second quarter of fiscal 2009 compared to the second quarter of fiscal 2008 was due to the change in product revenue sales mix and approximately half was due to the $11.0 million royalty revenue resulting from the Riverbed settlement. The 450 basis point increase in gross margin percentage during the six months ended September 30, 2008 compared to the prior year was primarily due to the change in product revenue sales mix. Over one-third of the gross margin improvement for the first six months of fiscal 2009 was due to the $11.0 million royalty revenue resulting from the Riverbed settlement. Branded sales comprised 66% of non-royalty revenue for both the second quarter and first six months of fiscal 2009 compared to 63% and 60% of non-royalty revenue for the second quarter and first six months of fiscal 2008, respectively. Sales of branded products typically generate higher gross margins than sales to our OEM customers. We expect our gross margin percentage in the second half of fiscal 2009 to remain approximately the same or decrease slightly from the results for the first six months of fiscal 2009. This expectation assumes certain improvements to offset lower gross margin pressure from decreased royalty revenue. Margin improvements due to product mix could be offset by increases in product costs caused by higher fuel prices and other economic factors.

Product Margin

Our product gross margin dollars were relatively unchanged in the second quarter of fiscal 2009 compared to fiscal 2008. Decreased product gross margin dollars for the first six months of fiscal 2009 were primarily due to decreased product revenue for the first six months of fiscal 2009 compared to the first six months of fiscal 2009.

Product gross margin rates increased 690 basis points and 460 basis points in the second quarter and first six months of fiscal 2009, respectively, primarily due to the shift in sales mix toward higher margin disk-based systems and software solutions and away from devices and non-royalty media. Product gross margin rates were favorably impacted by our higher proportion of product sales through branded channels. Cost cutting measures implemented during the prior fiscal year also contributed to improved product gross margins in the second quarter and first six months of fiscal 2009 compared to the same periods of fiscal 2008.

Service Margin

For the three and six months ended September 30, 2008 and 2007, service gross margins decreased 570 basis points and 280 basis points, respectively, largely due to service costs increasing at a higher amount and rate than service revenue increases. Service cost increases were higher for third party service providers, amortization of service parts for maintenance and salaries and benefits. Third party service providers are used to provide service to customers when the third party provider is more cost effective, frequently due to contractual response times and geographic coverage. Our outstanding balance of service parts for maintenance has increased from the prior year, in part due to new product offerings. Salaries and benefits have increased due to increased headcount to provide service to customers due to our larger installed base of branded products.
