Overland Storage Reports First Quarter Fiscal 2013 Results

San Diego, CA – November 14, 2012 – Overland Storage (NASDAQ: OVRL), a trusted global provider of effortless data management and data protection solutions across the data lifecycle, today reported financial results for its fiscal 2013 first quarter ended September 30, 2012.

Eric Kelly, President and CEO of Overland Storage, said, “With the successful launch of our new clustered NAS solution in October, we have three significant new branded products that are now positioned to gain traction in the marketplace as planned, and in less than a year, we have built a significant pipeline of new branded product opportunities that continues to grow. These new products have significantly expanded our total addressable market and have allowed us to participate in new opportunities not previously available to us.

“While our fiscal first quarter has historically been a seasonally down quarter, our lower than expected total revenue is largely due to the difficult macroeconomic environment in Europe and longer sales cycles, which we believe have similarly affected our competitors. While we continued to win new business in Europe, customers delayed taking product due to the market uncertainty, which negatively affected our revenue across all our product families and has tempered our outlook for our sales in the region. As a result, we are not reiterating our guidance regarding achieving non-GAAP profitability in the fourth quarter of calendar 2012, but we believe that with our strong branded product portfolio and growing pipeline of new business, we can achieve this profitability target by the end of our 2013 fiscal year.”

Patent Litigation:

Based on the Commission’s evaluation of the ‘581 mail slot patent, Overland filed a petition on November 8, 2012 arguing that claims 10,12 and 16 meet the new definition of “linear array” put forward by the Commission, as the Commission agrees, and thus the ITC now should decide for the first time whether the BDT products include all the other elements of these claims. If the ITC remands the ‘581 infringement issue on this basis, the Administrative Law Judge could find BDT’s products infringe claims 10, 12 and 16, which Overland believes will result in BDT no longer being allowed to ship products with mail slots into the United States.

Overland reported on October 26, 2012 that the United States International Trade Commission (ITC) released a Notice of Commission Decision in the infringement action filed by Overland Storage against IBM, Dell and BDT. Overland has previously reported that its ITC and District Court actions against IBM and Dell have been resolved by settlement. The Notice of Commission Decision makes several key findings regarding Overland Storage’s U.S. Patent No. 6,328,766, which relates to partitioning media elements in automated media devices, and its U.S. Patent No. 6,353,581, which relates to the “mail slot” feature in automated media devices. Overland views this decision by the full Commission as beneficial to pursuing patent suits in civil court and another step in the process of proving that BDT and others in the data storage industry have been using Overland’s intellectual property without permission. The company’s infringement case against BDT and its affiliates continues and Overland plans to pursue monetary damages against BDT in District Court.
