SonicWALL Announces Preliminary First Quarter 2009 Results

Company Announces Timing of First Quarter Earnings Conference Call and Webcast

SUNNYVALE, Calif., April 9, 2009 – SonicWALL, Inc. (Nasdaq: SNWL) today announced preliminary results for the quarter ended March 31, 2009.  The Company expects to report revenue of between $46 and $47 million, below the previously issued guidance of $48-$52 million, due to sluggish demand conditions across all geographic regions and product categories.  Despite these conditions, the Company experienced sequential growth in subscription services billings and deferred revenue and continued strength in cash flow from operations.

The Company expects first quarter non-GAAP earnings per share of approximately $0.07, higher than the previously issued guidance of $0.04-$0.06, due to ongoing expense control initiatives and gross margin performance ahead of expectations.  The Company expects GAAP earnings per share of $0.02-$0.03.

These results are preliminary and are subject to the completion of customary quarterly closing and review procedures by the Company’s management and independent auditors.

The Company will host a conference call to report its first quarter 2009 earnings results on Monday, April 27 at 5:00 pm Eastern Time, (2:00 pm Pacific Time).  All interested parties are invited to listen to SonicWALL Chief Executive Officer and President, Matt Medeiros, and Chief Financial Officer, Rob Selvi, present earnings results, business highlights and guidance for the second quarter of 2009.
