NEW YORK -- Facebook is placing a $19 billion bet on reaching its next billion mobile users with the acquisition of WhatsApp, a popular messaging service that lets people send texts, photos and videos on their smartphones.
The $19 billion deal is by far Facebook's largest and bigger than any that Google, Microsoft or Apple have ever done. But it is likely to raise worries that Facebook and other technology companies are starting to become overzealous in their pursuit of promising new products and services, said Anthony Michael Sabino, a St. John's University business professor.
"This could be seen as a microcosm of a bubble," Sabino said. "I expect there to be a lot of skepticism about this deal. People are going to look at this and say, 'Uh-oh, did they pay way too much for this?"
Facebook, for its part, is taking the long view. WhatsApp has 450 million monthly users, 70 percent of whom use it every day. The service is adding a million new users a day. There are 19 billion messages sent and 34 billion received via WhatsApp each day, in addition to 600 million photos and 100 million video messages.
At this rate, Facebook CEO Mark Zuckerberg is confident the app will reach a billion users. Services that reach that milestone, Zuckerberg said in a statement, "are all incredibly valuable."
It's an elite group to be sure — one that includes Google (which owns YouTube), Facebook itself and little else.
Facebook said Wednesday that it's paying $12 billion in 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 transaction 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.
Facebook's $1 billion Instagram deal seems like a bargain in retrospect. Capturing mobile users — and young people — was a big reason behind Facebook's 2012 purchase of the photo-sharing app. Even its reported $3 billion offer for disappearing-message app Snapchat pales in comparison. Snapchat spurned the bid.
The deal stunned Gartner analyst Brian Blau. "I am not surprised they went after WhatsApp, but the amount is staggering," he said.
The world's biggest social networking company likely prizes WhatsApp for its audience of teenagers and young adults who are increasingly using the service to engage in online conversations outside of Facebook, which has evolved into a more mainstream hangout inhabited by their parents, grandparents and even their bosses at work.
WhatsApp also has a broad global audience.
Zuckerberg said the service "doesn't get as much attention in the U.S. as it deserves because its community started off growing in Europe, India and
Latin America. But WhatsApp is a very important and valuable worldwide communication network. In fact, WhatsApp is the only widely used app we've ever seen that has more engagement and a higher percent of people using it daily than Facebook itself."
Blau said Facebook's purchase is a bet on the future. "They know they have to expand their business lines. WhatsApp is in the business of collecting people's conversations, so Facebook is going to get some great data," he noted.
In that regard, the acquisition makes sense for 10-year-old Facebook as it looks to attract its next billion users while keeping its existing 1.23 billion members, including teenagers, interested. The company is developing a "multi-app" strategy, creating its own applications that exist outside of Facebook and acquiring others. It released a news reader app called Paper earlier this month, and has its own messaging app called Facebook Messenger.
"Facebook seems to be in acknowledgement that people are using a lot of different apps to communicate," said eMarketer analyst Debra Aho Williamson. "In order to continue to reach audiences, younger in particular, it needs to have a broader strategy...not put all its eggs in one basket."
Facebook said it is keeping WhatsApp as a separate service, just as it did with Instagram, which it bought for about $715.3 million nearly two years ago.
At $19 billion, Facebook is paying $42 per WhatsApp user in the deal.
For Facebook, WhatsApp's huge user base, fast growth pace and popularity is worth the money.
"We want to provide the best tools to share with different sized groups and in different contexts and to develop more mobile experiences beyond just the main Facebook app, like Instagram and Messenger," Zuckerberg said in a conference call. "This is where we see a lot of new growth as well as a great opportunity to better serve our whole community."
WhatsApp, a messaging service for smartphones, lets users chat with their phone contacts, both one-on-one and in groups. The service allows people to send texts, photos, videos and voice recordings over the Internet. It also lets users communicate with people overseas without incurring charges for pricey international texts and phone calls. It's free to use for the first year and costs $1 per year after that. It has no ads.
"It'll be tempting to read this as a sign Facebook is scared of losing teens," said Forrester analyst Nate Elliot in an emailed note. "And yes, the company does have to work hard to keep young users engaged. But the reality is, Facebook always works hard to keep all its users engaged, no matter their age. Facebook is tireless in its efforts to keep users coming back."
Asked about the demographics of WhatsApp's users, Facebook finance chief David Ebersman said that, "if you look at the kind of penetration that WhatsApp has achieved, it sort of goes without saying that they have good penetration across all demographics, we would imagine.
That said, "it's not a service that asks you to tell them your age when you sign up," he added.
Facebook's shares fell $1.82, or 2.7 percent, to $66.24 in after-hours trading Wednesday after the deal was announced. Earlier in the day, the stock hit a 52-week high of $69.08.
