Sierra Wireless, Inc.

today announced it has executed a definitive agreement for the sale of substantially all of the assets and operations related to its AirCard® business to NETGEAR®, Inc.

for $138 million in cash plus approximately $6.5 million in assumed liabilities as of December 31, 2012. NETGEAR is a global networking company that delivers innovative products to consumers, businesses, and service providers. Sierra Wireless expects to realize net cash proceeds of approximately $100 million from the asset sale, after related taxes, expenses, and funds held in escrow. The transaction is expected to close in March 2013, subject to customary closing conditions. Under the transaction, NETGEAR will acquire the assets and operations of the AirCard business, including customer relationships, products, intellectual property, inventory, and fixed assets, and assume certain liabilities, including warranty commitments and other customer obligations. Approximately 160 employees, primarily in sales, marketing, and R&D, will be transferred to NETGEAR, as well as certain facilities in Carlsbad, CA and Richmond, BC. Upon completion of the transaction, Sierra Wireless's retained business will include its AirPrime™ embedded modules for M2M and Mobile Computing, AirLink® intelligent gateways and routers, and AirVantage™ M2M cloud product lines. Going forward, Sierra Wireless will be an M2M and connected device pure play company, focused on providing innovative hardware, software, and cloud-based solutions that work together to enable customers across a broad range of markets to connect their machines to the “Internet of Things.” Use of funds Sierra Wireless intends to use net proceeds from the transaction to continue its acquisition strategy in the M2M market, with the objective of accelerating revenue and earnings growth by strengthening its leadership in existing markets and expanding its position in the M2M value chain. Sierra Wireless is also exploring alternatives to return a portion of the proceeds to shareholders and will seek approval of the Toronto Stock Exchange (“TSX”) to undertake a normal course issuer bid (“NCIB”). The terms of the proposed NCIB will be subject to TSX review and approval, and Sierra Wireless expects to provide further details in the coming weeks. Financial highlights for the fourth quarter and full year 2012 Sierra Wireless expects consolidated fourth quarter 2012 results to be solidly in line with guidance provided on November 1, 2012. Preliminary revenue for the full year is $644 million. With respect to the retained business, preliminary fourth quarter and full year 2012 revenues were $109 and $397 million, respectively, including $14.0 million and $61.1 million, respectively, in revenue from the sale of AirPrime embedded wireless modules to Mobile Computing customers. Non-GAAP gross margin for the retained business was 33.2 percent in the fourth quarter of 2012 and 31.6 percent for the full year. Non-GAAP earnings from operations for the retained business were modestly positive in the fourth quarter, showing a steady improvement throughout the year. “Upon closing this transaction, we will be highly focused on driving profitable revenue growth in our M2M business,” said David McLennan, Chief Financial Officer of Sierra Wireless. “As a stand-alone business, we will have a cost structure that supports considerably higher revenue levels, which will initially be reflected in modest operating margins. However, because we will be fully invested for growth, as we increase our revenues we expect to see greater operating leverage from the business.” Sierra Wireless will release fourth quarter and fiscal 2012 financial results after market close on February 6, 2013. Management will provide additional financial detail at that time.
