Sierra Wireless Announces Expense Reduction Program

VANCOUVER, BRITISH COLUMBIA - Sierra Wireless, Inc. (NASDAQ: SWIR, TSX: SW) announced today that it is implementing an expense reduction program.

The expense reduction program is expected to reduce labor costs by approximately $5.5 million on an annualized run rate basis.  The program includes the elimination of approximately 56 positions, representing 10% of the company’s workforce.   The positions eliminated will impact all levels and functions of the company.  These actions are expected to be largely completed during the first quarter of 2009.  The company expects to incur a pre-tax charge of approximately $1.3 million in the first quarter for severance and other costs related to this program.

“We have experienced strong revenue growth over the past three years and have significantly expanded our team size.  We also believe that our product portfolio and channel position in key markets remains strong.  However, based on the expectation that economic uncertainty will continue for the foreseeable future, we felt it was prudent to reduce our cost structure now, in order to mitigate the potential impact of this uncertainty on our business”  said Jason Cohenour, President and Chief Executive Officer.

We will host a conference call to review our fourth quarter 2008 results on Tuesday, February 10th, 2009 at 5:30pm Eastern time. To participate in this conference call, please dial 1-800-733-7560 or 1-416-644-3414  approximately ten minutes prior to the commencement of the call.  The call will also be broadcast over the Internet (http://www.newswire.ca/en/webcast/viewEvent.cgi?eventID=2503820)
