Sierra Wireless Expands Its Managed Connectivity Services Offering with Acquisition of Accel Networks

Sierra Wireless agrees to purchase Florida-based Accel Networks,
a leading provider of 4G LTE managed connectivity service for distributed enterprises.

VANCOUVER, British Columbia & ST. PETERSBURG, Fla.--(BUSINESS WIRE)--May 7, 2015--Sierra Wireless (NASDAQ: SWIR) (TSX: SW) and Accel Networks today announced that Sierra Wireless has entered into a definitive agreement to acquire Accel. The transaction is expected to close in June 2015.

“We are excited to join forces with our long-time partner Accel Networks as we see strong strategic alignment providing secure, managed connectivity solutions for the distributed enterprise, as well as for the broader Internet of Things,” said Jason Cohenour, President and CEO of Sierra Wireless. “With a proven managed connectivity service adopted by hundreds of enterprises in the U.S., the addition of Accel will accelerate our device-to-cloud strategy and add significant scale and capabilities to our services business.”

Accel Networks provides primary and back-up connectivity services to more than 300 enterprise customers in sectors such as retail, finance, security, energy, and hospitality. With 4G LTE providing high connectivity speeds and legacy carriers transitioning away from copper-based networks, many enterprises are adopting wireless connectivity. Accel enables this migration without sacrificing reliability or performance. Accel’s managed connectivity service and wireless link optimization solution transforms a cellular link into an enterprise-class last-mile connection that equals or exceeds terrestrial broadband.

“Since founding the company in 2002, we have been successful in building a strong customer base by developing solutions that overcome the challenges of utilizing cellular for mission-critical networking and by delivering robust indoor connectivity in a highly cost-effective manner,” said Mark Gianinni, co-founder and CEO of Accel Networks. “Looking forward, we are excited to join Sierra Wireless to further expand our offering and accelerate our growth.”

Accel Networks provides a complete end-to-end solution – integrating 4G LTE gateways and the iMaestro™ antenna, with cloud-based radio frequency link optimization and remote management. Combined with high-speed LTE connectivity from leading network operators including AT&T, Verizon, and Sprint, the Accel solution enables distributed enterprises to rely on cellular-based connectivity for their most critical applications, including PCI-compliant secure communications. Accel deploys their managed connectivity services with customers directly, as well as with key channel partners such as Trextel.

“Accel Networks is an important partner for Trextel. The iMaestro platform, in combination with AT&T, powers our 4G LTE managed connectivity service offering,” said Jason Morrow, CEO of Trextel Solutions. “We are excited that Accel is joining Sierra Wireless and we look forward to working together to expand the offering and provide even more value for our customers.”

Accel Networks was founded in 2002 and is headquartered in Florida, with its primary operations center located in Georgia. The company currently employs 28 full time staff.
