Sierra Wireless Reports First Quarter 2004 Results

VANCOUVER, BRITISH COLUMBIA - Sierra Wireless, Inc. (NASDAQ: SWIR, TSX: SW) is
reporting better than expected first quarter results, including revenue of $41.6
million, a profit of $4.6 million and positive cash flow from operations. These
results are being released earlier than the previous schedule of April 22, 2004.

Our results are reported in US dollars and are prepared in accordance with
United States generally accepted accounting principles.

"Once again, our revenues were up significantly, reflecting growing demand for
our AirCard, Embedded Module and Mobile product lines, with notable strength in
North American markets", said David Sutcliffe, Chairman and Chief Executive
Officer. "Investment continues in market development and new products including
the Voq Professional Phone and the AirCard 775 for EDGE networks. We continue to
focus on profitable growth."

Results for the first quarter of 2004, relative to company guidance provided on
January 28, 2004 and, for certain measures, updated on April 1, 2004:

     First quarter revenue for 2004 of $41.6 million was consistent with our
     guidance of revenues greater than $40.0 million. Gross margin was 40.3%,
     better than our guidance range of 39.0% to 40.0%. Our net earnings of $4.6
     million, or diluted earnings per share of $0.18, exceeded our guidance of
     net earnings greater than $3.0 million, or diluted earnings per share of
     greater than $0.12. Our cash flow from operations was positive $5.3
     million, consistent with our guidance of significantly positive cash flow.

Results for the first quarter of 2004, compared to the first quarter of 2003:

     Revenue for the first quarter of 2004 increased by 107% to $41.6 million,
     from $20.1 million for the same period in 2003. Gross margin improved to
     40.3% from 39.4%. Operating expenses were $11.6 million in the first
     quarter of 2004, compared to $7.6 million for the same period in 2003. Net
     earnings for the first quarter of 2004 were $4.6 million, or diluted
     earnings per share of $0.18, compared to net earnings of $0.4 million, or
     diluted earnings per share of $0.02, in the first quarter of 2003.

     During the first quarter of 2004, we signed a second agreement with the
     Government of Canada's Technology Partnerships Canada ("TPC") under which
     we are eligible to receive conditionally repayable research and development
     funding up to Cdn. $9.5 million. The agreement is effective for development
     work, relating to third generation wireless technologies, commencing April
     2003. Funding of $1.4 million was recognized as a reduction of research and
     development expense in the first quarter of 2004, of which $1.1 million
     relates to the period from April 1, 2003 to December 31, 2003.

     Operating expenses for the first quarter of 2004 were $12.9 million,
     excluding TPC funding related to 2003 of $1.1 million and an additional
     Metricom recovery of $0.2 million. Net earnings for the first quarter of
     2004, excluding these amounts, were $3.3 million, or diluted







     earnings per share of $0.13. Our results for the first quarter of 2004 also
     included a foreign exchange loss of approximately $0.3 million.

     Our revenue increased in the first quarter of 2004, compared to the first
     quarter of 2003 due primarily to an increase in sales of embedded module
     and AirCard products. Our margin improved in the first quarter of 2004
     primarily due to increased volume and product mix. Our operating expenses
     increased in the first quarter of 2004, compared to the first quarter of
     2003 due primarily to the acquisition of AirPrime, Inc., which was
     completed in August 2003, and costs related to the development of new
     products, including EDGE and the Voq professional phone.

Results for the first quarter of 2004, compared to the fourth quarter of 2003:

     Revenue for the three months ended March 31, 2004 amounted to $41.6
     million, compared to $34.6 million in the fourth quarter of 2003, an
     increase of 20%. Gross margins were $16.8 million or 40.3% in the first
     quarter of 2004, compared to $14.2 million or 41.1% in the fourth quarter
     of 2003. Operating expenses were $11.6 million in 2004, compared to $13.0
     million in the previous quarter. Operating expenses, excluding the TPC
     funding related to 2003 and the additional Metricom recovery, were $12.9
     million in the first quarter of 2004, compared to $12.1 million, excluding
     integration costs, in the fourth quarter of 2003.

     Net earnings were $4.6 million for the three months ended March 31, 2004,
     compared to net earnings of $1.9 million for the three months ended
     December 31, 2003. Excluding TPC funding related to 2003 and the Metricom
     recovery, net earnings for the first quarter of 2004 were $3.3 million, or
     diluted earnings per share of $0.13, compared to net earnings in Q4 2003 of
     $2.8 million, excluding integration costs, or diluted earnings per share of
     $0.12.

First Quarter Highlights Included:

Progress on products for CDMA 2000 networks and channels:

o        We have provided next generation wireless technology to the Harris
         County Sheriff's Office in Texas that is outfitting approximately 600
         patrol vehicles and 300 detectives with a high-speed mobile solution
         powered by the Sierra Wireless AirCard(R) 555.

o        The Sierra Wireless MP 555 GPS rugged wireless modem has been certified
         by Sprint for operation on the enhanced Sprint Nationwide PCS Network.
         We will work with Sprint to market and sell the MP 555 GPS in-vehicle

         departments.

o        We added the Sierra Wireless AirCard 555R to our product line for the
         China market. Operating on CDMA 1X networks, the AirCard 555R will
         provide mobile professionals with wireless data access and will be
         distributed by Beijing Putian Taili Telecom.

o        Verizon Wireless, Citrix Systems, Inc., and Zumasys, Inc., announced

         a mobile access solution combining Citrix(R) MetaFrame(R) Presentation
         Server and Verizon Wireless' BroadbandAccess high-speed wireless
         service. Currently available in San Diego and Washington D.C., Verizon
         Wireless plans to make BroadbandAccess service available throughout
         additional portions of its network beginning later this year.





Progress on products for GSM/GPRS/EDGE networks and channels:

         throughput on the market today and a superior network interface for
         fast and reliable mobile computing.

o        Together with Analog Devices, Inc. (ADI) and TTPCom, we announced that
         we will bring wireless EDGE (Emerging Data rates for Global Evolution)
         capabilities to laptop computers and personal digital assistants. We
         have selected ADI's Blackfin SoftFone for EDGE Platform and TTPCom's
         protocol stack software, to power our new Sierra Wireless AirCard 775
         PC Card for the EDGE network.

         users with faster data rates, reaching speeds up to three times faster
         than on GPRS networks, offering an enhanced user experience and

         the next generation mobile product that provides in-vehicle data
         solutions while operating over EDGE and GSM/GPRS networks. The AirCard
         775 and MP 775 are expected to be commercially available in the second
         half of 2004.
