Dot Hill Systems Corp. (Nasdaq: HILL), a provider of world-class storage solutions and software for OEMs, open storage partners and system integrators, today provided guidance for the second quarter of 2010 and announced a restructuring plan intended to enable the company to achieve non-GAAP EBITDA break-even by the fourth quarter of 2010.

Guidance for Second Quarter 2010
Following a comprehensive financial review and with its restructuring plan now underway, the Company anticipates second quarter 2010 net revenue to be in the range of $62 to $65 million and a non-GAAP net loss per share in the range of $0.07 to $0.10. Management expects cash and cash equivalents on June 30, 2010 to be between $40 and $43 million.

Restructuring Details
The Company additionally announced the implementation of a restructuring and cost reduction plan, referred to as the 2010 Plan, that will include severance and related costs for an approximate 10% reduction in its global workforce and the acceleration of the closure of the Company’s Carlsbad, California facility. The Company expects to record severance costs in the range of $300,000 to $500,000 and facility reduction costs in the range of $200,000 to $350,000 in connection with the 2010 Plan. In addition, the Company announced a 10% reduction in the annual base salaries of its vice-president and executive management teams, including the Company’s President and Chief Executive Officer and Chief Financial Officer, and a 5% reduction in the annual base salaries of certain of its employees below the vice-president level.

“We expect to realize the majority of the benefits associated with these actions starting July 1,” said Dana Kammersgard, President and Chief Executive Officer. “The aggregate benefit is a significant reduction in break-even levels and our projections indicate that we should break-even on a non-GAAP EBITDA basis by the fourth quarter of 2010. In our last earnings call, I indicated our intent to break-even at between $60 million to $65 million in quarterly revenues, depending on product and customer mix. I believe these actions should enable consistent financial improvements throughout the remainder of this year and achievement of this objective.”
