Facebook's Wild Growth Continues

Despite Facebook's (NASDAQ: FB) better-than-expected fourth-quarter revenue and earnings-per-share growth, there were still challenges CEO Mark Zuckerberg turned investors' attention toward. Specifically, he said Facebook's recent efforts to prioritize meaningful connections over passive consumption of content reduced time spent on the platform.

Nevertheless, the quarter featured extraordinary growth in revenue, active users, and profits, as well as an optimistic outlook for advertising revenue growth.

The raw numbers

So much for a deceleration in Facebook's revenue growth in Q4. Fourth-quarter revenue surged 47% higher than a year ago. That was the same year-over-year revenue growth rate Facebook reported in its third quarter. The sharp increase was driven primarily by a 48% year-over-year boost to its advertising revenue.

Though operating costs increased 32% year over year, Facebook's outsize revenue growth meant that earnings per share, when excluding the impact of the 2017 Tax Cuts and Jobs Act on earnings, soared 83%. Including this $0.77 charge to Facebook's fourth-quarter earnings per share, EPS still climbed 19% year over year.

Facebook's active user count marched higher, even as total time spent on the social network during the quarter decreased. Monthly active users were 2.13 billion, up 14% year over year and about 3% sequentially.

Fourth-quarter highlights

  • Zuckerberg said changes to its news feed led to a total of approximately 50 million fewer hours spent on Facebook every day.
  • Measured another way, time spent on Facebook decreased about 5% in Q4.
  • Similar to its growth in monthly active users, daily active users increased nicely, rising 14% year over year to 1.4 billion. On a sequential basis, daily active users were up about 2%.
  • But daily active users didn't increase in every market. In "some countries," Facebook saw a decline in daily active users after its changes to improve the quality of its news feed, management said in its fourth-quarter conference call.

Outlook

Even as time spent on Facebook decreased during the quarter, the social network still believes revenue growth in 2018 is going to be incredibly strong. Management said it expected its ad revenue growth rates during the year to "decelerate consistent with the trends we have seen over the past year" -- a notable forecast, considering quarterly year-over-year growth rates for advertising revenue decelerated only from 51% in the first quarter of 2017 to 48% in Q4.

Facebook CFO David Wehner explained the drivers behind the company's expectations for strong revenue growth:

Facebook's continued optimism for business growth even as recent changes reduce time spent on the platform reflect management's belief that time spent on Facebook after these changes will be more valuable.

Zuckerberg explained:

But management still expects huge expense growth in 2018, driven by aggressive investments in security, video content, and long-term initiatives around augmented and virtual reality, artificial intelligence, and connectivity. Facebook expects 2018 expenses to rise 45% to 60% compared with 2017.
