Arris Group Inc. agreed to buy Motorola Mobility LLC’s “Motorola Home” business from Google Inc. for $2.35 billion US in cash and stock, the companies said Wednesday. In a release, the companies said Arris will spend $2.05 billion US in cash to acquire the division, owned by parent company Google, which offers set-top boxes and other Internet-connected devices designed for the home. Google will also receive a 15.7 per cent ownership stake in Arris as a part of the deal, the release said. “Together, ARRIS and Motorola Home will have a global presence with over 500 customers in 70 countries, more than tripling ARRIS pro forma combined revenue to approximately $4.7 billion for the trailing four quarter period ended September 30, 2012,” the release said. “The combined entity will offer a wide array of products and solutions and will have an expanded customer base encompassing the full spectrum of broadband content and service providers.” Motorola Home accounted for $3.4 billion in revenue in the 12-month period ended Sept. 30, 2012, and the combination of the two companies is expected to generate between $100 million US and $125 million US “in annual cost synergies,” the release said. The deal, which has been approved by the boards of each company, is expected to close by the second quarter of 2013, the release said. Shaw Communications Inc. uses platforms operated by both Arris and Motorola in its digital cable operations, predominantly in Western Canada.
