Sierra Wireless Reports First Quarter 2007 Results

VANCOUVER, BRITISH COLUMBIA – Sierra Wireless, Inc. (NASDAQ:  SWIR, TSX:  SW) is reporting first quarter 2007 results.

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

“The first quarter of 2007 was a period of record revenue, improved profitability, new product launches and strategic milestones,” said Jason Cohenour, President and Chief Executive Officer. “During the first quarter, we experienced strong sales growth, achieving record quarterly revenue of $85.4 million in what is often a seasonally soft period.  Our revenue growth was driven primarily by increased sales of our HSDPA and EV-DO AirCard products to existing wireless operator channels.  Our strong revenue result, combined with a slight improvement in gross margin, helped drive significantly improved operating profit of $5.5 million – our best quarterly operating profit result in more than two years. “

“As expected, the first quarter was also a busy period for new product launches.  By the end of the quarter, we commenced initial commercial shipments of three new and important products:  our 3G MPs for both HSDPA and EV-DO and our new USB modem for HSDPA.  We also announced an agreement with Sprint to launch our new EV-DO USB modem for use on the Sprint Mobile Broadband Network.  We expect all four of these new products to be important contributors to our financial results in the coming quarters.  While executing on our business, we also achieved an important strategic milestone, announcing the completion of a definitive agreement to acquire AirLink Communications, Inc.  We believe the acquisition of AirLink will significantly expand our high gross margin product lines and establish Sierra Wireless as a leader in the rugged mobile and M2M connectivity segments.  Looking forward, we expect that our current product portfolio and expanded roster of channels, combined with more new product releases and the addition of AirLink, will drive continued revenue growth and improving profitability.”

First Quarter Highlights Included:

·We announced an agreement with Sprint to supply our new AirCard 595U USB modem for use on the Sprint Mobile Broadband EV-DO Rev A Network. The Sprint Mobile Broadband USB Modem (AirCard 595U) is now available in Sprint sales channels, including retail stores.

·We announced commercial availability of the AirCard 875 with Telefónica Móviles España. Telefónica was the first European network operator to launch our AirCard 875 PC card.

·We announced that debitel added our AirCard 875 to its SURF@go product line up for connectivity to 3G and HSDPA networks in Germany.

·We announced that the AirCard 875 is available in Australia through Telstra for use on Telstra’s Next GTM HSDPA network.

·We announced that the Sierra Wireless AirCard 595 wireless wide-area network card will be the first card available in Canada capable of operating on TELUS’ High Speed EV-DO Rev A network.

·FlipStart Labs selected our embedded modules to provide mobile broadband connectivity to the FlipStart super compact PC, which features a unique small clamshell design and full Windows support.

·We announced that Cisco Systems has integrated our 3G embedded modules into the new Cisco 3G Wireless Wide Area Network (WAN) High-Speed WAN Interface Card (HWIC) solution for Cisco Integrated Services Routers.  The new 3G Wireless HWIC solution is expected to deliver WAN fail-over and rapid deployment capability to new and existing Cisco Integrated Services Routers.

·Together with Isochron, we announced that Isochron selected our embedded modules to provide high-speed wireless connectivity for its innovative VendCast vending management solution.

·We expanded our relationship with Flextronics, our manufacturing partner, to add a configuration and distribution center for our products in Zalaegerszeg, Hungary, due to increased customer activity in the EMEA region. The Zalaegerszeg Center is now operational and supporting configuration, customization, packout, warehousing and reverse logistics for our EMEA customers.

·We introduced new AirCards and embedded modules for HSUPA networks that will improve the speed at which mobile users can work, supporting theoretical uplink speeds of 2 Mbps and downlink speeds of 7.2 Mbps.  We expect to commence commercial shipments of our HSUPA PC cards, ExpressCards and embedded modules mid 2007.

Financial Guidance

The following guidance for the second quarter of 2007 reflects our current business indicators and expectations. Our guidance for the second quarter includes a higher than usual revenue contribution from new product and channel launches.  As a result of this activity, we expect our second quarter operating expenses to increase relative to the first quarter.  There are uncertainties associated with the launch and early ramp of new products that could affect our ability to achieve guidance.  Inherent in this guidance are risk factors that are described in detail in our regulatory

filings. Our actual results could differ materially from those presented below. All figures are approximations based on management’s current beliefs and assumptions.

			Non GAAP Adjustments
Q2 2007 Guidance (Excluding AirLink Acquisition)	GAAP		Stock Comp		Acquisition Amortization (1)		Non GAAP
Revenue	$	92.0 million					$	92.0 million
Earnings from operations	$	6.0 million	$	1.0 million	$	0.3 million	$	7.3 million
Net earnings	$	5.5 million	$	0.8 million	$	0.2 million	$	6.5 million
Diluted earnings per share	$	0.21/share					$	0.25/share

(1)  Represents purchase price amortization associated with the 2003 acquisition of AirPrime, Inc.

We believe that we are on track to close the AirLink acquisition by the end of Q2 2007.  There may be an opportunity to complete the acquisition as early as the end of May.  If so, including AirLink for one month in the second quarter would positively impact revenue by approximately $2.0 million.  The estimated AirLink impact incorporates the elimination of intercompany sales.
