NEW YORK - Facebook is buying mobile messaging service WhatsApp for $19 billion in cash and stock, by far the company's largest acquisition and bigger than any that Google, Microsoft or Apple have ever done.
The world's biggest social networking company said Wednesday that it is paying $12 billion in Facebook stock and $4 billion in cash for WhatsApp. In addition, the app's founders and employees - 55 in all - will be granted restricted stock worth $3 billion that will vest over four years after the deal closes.
The deal translates to roughly 11 percent of Facebook's market value. In comparison, Google's biggest deal was its $12.5 billion purchase of Motorola Mobility, while Microsoft's largest was Skype at $8.5 billion. Apple, meanwhile, has never done a deal above $1 billion.
