	•		Cash and investments totaled $131.3 million at March 31, 2010, compared with $123.8 million at December 31, 2009. The company generated $8.8 million in cash from operations.

“First quarter results were consistent with the updated guidance we provided in early April,” said Phil Soran, President and CEO of Compellent. “Revenue declined on a sequential basis, but the remaining components of our income statement improved. We had a substantial increase in gross margin and reduced growth in operating expenses compared to recent quarters. Our first quarter new customer growth demonstrates our strength.”

“Looking ahead, we remain confident in the growth prospects for Compellent,” Mr. Soran continued. “We continue to see strong demand from midsized and larger enterprises who appreciate the benefits of our unique storage solution. The introduction of our zNAS unified storage offering announced yesterday is one example of new products that we anticipate will expand our addressable market. We believe the efficiency of our business model and the strong relationships we enjoy with our channel partners are critical to our success. We have the financial resources to pursue our growth strategy.”

Non-GAAP Measures

To supplement the company’s Statements of Operations presented in accordance with GAAP, the company uses non-GAAP measures for operating income (loss) and net income (loss). In order for investors to be better able to compare the company’s current results with those of previous periods, the company has shown a reconciliation of the GAAP to non-GAAP financial measures at the end of this press release. This reconciliation adjusts the related GAAP financial measures to exclude stock-based compensation expense. The company believes the presentation of these non-GAAP financial measures enhance the user’s overall understanding of the company’s historical financial performance. The presentation of non-GAAP measures is not meant to be considered in isolation or as a substitute for the company’s financial results prepared in accordance with GAAP, and the company’s non-GAAP financial measures may be different from non-GAAP financial measures used by other companies.
