Google and Motorola Mobility have announced an agreement whereby Google will acquire Motorola for $12.5 billion. The acquisition price equates to $40 per share of Motorola stock, or a premium of 63% over Friday’s closing price. The move is considered in part to be an effort that will better-align Google to compete with Apple’s iPhone, which owned two-thirds of profits among the world’s top-8 smartphone vendors in the second quarter. A Google-owned hardware arm give the company complete control over device hardware, software and services, resulting in an end-to-end user experience that is completely under Google’s command. Perhaps just as important in this day and age, the deal will also give Google control of Motorola’s extensive patent portfolio. “Motorola Mobility’s total commitment to Android has created a natural fit for our two companies,” Google CEO Larry Page said in a statement. “Together, we will create amazing user experiences that supercharge the entire Android ecosystem for the benefit of consumers, partners and developers. I look forward to welcoming Motorolans to our family of Googlers.” It is unclear how this might affect Google’s relationship with other Android partners. The deal is subject to regulatory approval, of course, and it is expected to close in late 2011 or early 2012. The full press release follows below.
