Facebook had a volatile aftermarket as shares whipsawed from green to red to green in extended trading, with the company eking out a profit to beat Wall Street’s expectations but missing key forecasts on revenue and active users.

The social network reported slowing user growth, with 1.49 billion daily active users in the third quarter versus the 1.51 billion that analysts had expected. Facebook also missed predictions for monthly active users, reporting 2.27 billion, short of the forecast 2.29 billion.

It missed on revenue, posting $13.73 billion against estimates of $13.78 billion. Facebook blamed $159 million in currency-exchange headwinds for the discrepancy.

Chief executive Mark Zuckerberg was able to beat estimates on Facebook’s earnings, reporting $1.76 per share, compared with the $1.47 that Wall Street had anticipated.

Shares were down as much as 4.3 percent after hours before climbing as much as 5 percent, to $153.72, as Zuckerberg explained the growth of the Stories platform during a conference call with analysts.

Facebook said its family of social networking apps, including its main network plus sister apps Instagram and WhatsApp, now have more than 2.6 billion people using them each month — up 100 million from last quarter.

In a call with investors, Zuckerberg said Facebook will keep pushing its service to be more private and secure.

“It’s been a tough year, but we’ve made a lot of progress on our toughest issues,” Zuckerberg said. “We will never be perfect, but I’m proud of the work we’ve been doing here.”
