Facebook's WhatsApp Acquisition Now Has Price Tag of $22 Billion

Facebook Inc closed its acquisition of mobile messaging service WhatsApp on Monday, with the final price tag rising an additional $3 billion to roughly $22 billion because of the increased value of Facebook's stock in recent months.

WhatsApp founder Jan Koum will receive nearly $2 billion in stock, vesting over a four-year period, as an inducement for him to stay with the company, according to a regulatory filing on Monday.

The acquisition, which Facebook announced in February and recently received regulatory approval in Europe, underscores the sky-rocketing values of fast-growing Internet startups, and the willingness of established players such as Facebook and Google Inc to pay out for them.

WhatsApp, which has more than 600 million monthly users, is among a new crop of mobile messaging and social media apps that have become increasingly popular among younger users. Snapchat, a privately owned mobile app that allows users to swap photos that can disappear after a few seconds, is raising money at a $10 billion valuation, according to media reports.

Facebook paid $4.59 billion in cash and 178 million shares of its stock for WhatsApp, as well 46 million of grants in restricted stock units for WhatsApp employees that will vest over a four year period. At Monday's opening Facebook share price of $77.17, the deal translates to roughly $21.8 billion.

Koum, who will serve as WhatsApp Chief Executive and become a Facebook director, will earn a $1 annual salary, similar to Facebook Chief Executive Officer Mark Zuckerberg. Koum will receive 24.9 million Facebook restricted stock units, worth roughly $1.9 billion at Monday's share price.

WhatsApp, which has more than 70 employees, will continue to be based at its Mountain View, California, location.
