Facebook beats expectations thanks to strong user growth

Check out the latest Facebook earnings call transcript.

Coming into Facebook's fourth-quarter report, investors were worried that the social media giant was losing users due to a variety of scandals and privacy concerns, but the company reported strong user growth and beat expectations for both the top and bottom lines. Shares soared 10.8%.

Daily active users (DAUs) grew 9% to 1.52 billion in December and monthly active users also jumped 9% to 2.32 billion, or 31% of the world's population. Facebook also reported the first increase in DAUs in the U.S. and Canada in three quarters, to a record 186 million.  

Revenue grew 30.4% to $16.9 billion, topping estimates of 16.4 billion. Earnings per share of $2.38 handily beat the analyst consensus of $2.19. Average revenue per user jumped 19% year-over-year and 21% sequentially to $7.37.

Facebook has been investing heavily in addressing social issues and improving privacy, growing expenses by 62% and head count by 42%. CEO Mark Zuckerberg said in the conference call that the company will continue these efforts as its first priority, but this year also will be allocating more energy to "building new and inspiring ways to help people connect and build community."

The production rate of the Model 3 improved 13% over Q3, with 63,359 vehicles delivered. With Model 3 shipments nearing 140,000 for the year, Tesla said it was the best-selling premium vehicle in the U.S. for 2018.

Looking forward, the company expects to produce Model 3s at a rate of 7,000 units per week by the end of the year and annualized output "in excess of 500,000 units sometime between Q4 of 2019 and Q2 of 2020."
