Sierra Wireless Reports Third Quarter 2007 Results

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

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

“During the third quarter of 2007 we experienced continued strong momentum in our business and achieved record quarterly revenue and earnings” said Jason Cohenour, President and Chief Executive Officer.  “Our strong results were driven by a combination of continued solid shipments of our AirCard products to existing operator channels, initial shipments of our new HSUPA products, growth in our OEM business and a full quarter of contribution from AirLink.  These factors contributed to year over year revenue growth of 112%, improved gross margin and a significantly improved operating margin of 10.4%.  During the quarter, our channels reported record sell through of our products and our bookings were strong.  These trends, combined with new HSUPA product momentum, give us good revenue visibility and support our expectations for growth and improved profitability in Q4.

Early in Q4, we also achieved an important strategic milestone, closing a new equity issue and raising gross proceeds of $85.1M.  We intend to use the net proceeds from this transaction to help fuel the execution of our strategy, including potential acquisitions that we believe will help drive further gains in shareholder value.”

Q3 2007 Financial Results

Our revenue for the third quarter of 2007 amounted to a record $111.5 million, gross margin was $33.1 million, or 29.7% of revenue, operating expenses were $21.4 million and net earnings were $9.0 million, or diluted earnings per share of $0.33.  Integration costs related to the AirLink Communications, Inc. (“AirLink”) acquisition were not material in the third quarter of 2007.  Our balance sheet remains strong, with $102.8 million of cash and short and long-term investments, which includes the generation of cash from operations of $14.2 million and excludes the proceeds raised from the equity issue that closed in early Q4.

Results for the third quarter of 2007, relative to guidance provided on July 26, 2007 are as follows:

Third quarter revenue for 2007 of $111.5 million was better than our guidance of $109.0 million. Our earnings from operations were $11.6 million, better than our guidance of $9.4 million.  Our net earnings of $9.0 million, or diluted earnings per share of $0.33, were also better than our guidance of net earnings of $7.6 million, or diluted earnings per share of $0.27.

Results for the third quarter of 2007, compared to the third quarter of 2006 are as follows:

Third quarter revenue increased by 112% to $111.5 million in 2007 from $52.5 million for the same period in 2006. Gross margin for the third quarter of 2007 was 29.7% of revenue, compared to 30.2% for the same period in 2006. Operating expenses were $21.4 million in the third quarter of 2007, compared to $15.8 million in the same period of 2006. Net earnings for the third quarter of 2007 were $9.0 million, or diluted earnings per share of $0.33, compared to net earnings of $1.1 million, or diluted earnings per share of $0.04, in the same period of 2006.

Our third quarter results for 2007 include a full quarter of contribution from AirLink. AirLink contributed revenue of $9.5 million at a gross margin of 53.2% in the third quarter of 2007.

Included in our results are stock-based compensation expense and amortization resulting from the acquisitions of AirPrime, Inc. in 2003 and AirLink in May 2007.  Adjusting for these amounts, our non-GAAP results are as follows:

Results for the third quarter of 2007, compared to the second quarter of 2007 are as follows:

Revenue for the third quarter of 2007 increased by 4% to $111.5 million, compared to $107.4 million in the second quarter of 2007. Gross margin was 29.7% of revenue in the third quarter of 2007, compared to 27.0% in the second quarter of 2007. Operating expenses were $21.4 million in the third quarter of 2007, compared to $20.9 million in the second quarter of 2007. Net earnings for the third quarter of 2007 were $9.0 million, or diluted earnings per share of $0.33, compared to net earnings of $6.7 million, or diluted earnings per share of $0.25, in the second quarter of 2007.

Third Quarter Highlights Included:

•Commercial availability of our AirCardÒ 595U USB modem from Verizon Wireless for use on Verizon’s Broadband Access service.

•Commercial availability of the AirCard 595U USB modem and the AirCard 597E ExpressCard from Telecom New Zealand for use on the Telecom Mobile Broadband service.

•Commercial availability of our AirCard 595 PC card and the AirLink PinPoint X and Raven X products from Bell Mobility of Canada for use on Bell’s high-speed EVDO Rev A network.

•Commercial availability of the new HSUPA AirCard 880U USB modem and AirCard 880E ExpressCard from Telstra of Australia for use on Telstra’s Enhanced Next G™ HSPA network.

•Together with Fujitsu PC Asia Pacific, we announced that our MC8780 embedded module is integrated into the new LifeBook P7230 and S6410 to provide HSUPA mobile broadband connectivity. Both platforms are now commercially available in Hong Kong for use on the SmarTone-Vodafone network and in Japan for use on the NTT DoCoMo network.

•We announced a bought deal to raise gross proceeds of US$78.4 million from the sale of 3,500,000 common shares in the United States and Canada at a price of US$22.40 per share.  On October 2, 2007, after the quarter end, we closed the offering and sold 3,800,000 common shares from treasury, which included 300,000 shares issuable upon the exercise by the underwriters of the over-allotment option.  Gross proceeds of this offering were $85.1 million. We expect to use the net proceeds from the offering for general corporate purposes, working capital and potential future acquisitions.

Financial Guidance

The following guidance for the fourth quarter of 2007 reflects our current business indicators and expectations.

Our revenue expectations for the fourth quarter of 2007 are driven by strong demand that is moderated by expected supply constraints on some components.

Similar to the third quarter of 2007, our guidance for the fourth quarter includes a significant revenue contribution from expected new product and channel launches.  There are uncertainties associated with the launch and early ramp of new products that could affect our ability to achieve guidance.  As a result of our anticipated new product launch activity, we expect fourth quarter operating expenses to increase relative to the third quarter.

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.
