The social media platform earned $5.1 billion, or $1.74 per share, for the second quarter.

“Our community and business continue to grow quickly. We are committed to investing to keep people safe and secure, and to keep building meaningful new ways to help people connect,” said CEO Mark Zuckerberg in a statement.

The daily active users (DAUs) were 1.47 billion as of June 30, also an increase of 11 per cent year-over-year.

Analysts attributed the slow user growth to the European privacy law that went into effect on May 25.

Mobile advertising revenue represented approximately 91 per cent of advertising revenue for the second quarter of 2018 — up from approximately 87 per cent of advertising revenue in the second quarter of 2017.

Facebook currently employs 30,275 people — an increase of 47 per cent year-over-year.

“We expect revenue growth rates to continue to decelerate in the second half,” said David Wehner, Chief Financial Officer.

In April, Facebook had warned investors that more users’ data scandals in the future may adversely affect the social networking giant’s reputation and brand image.

Appearing before the US Congress, Zuckerberg told the lawmakers that his own personal data was part of 87 million users’ that was “improperly shared” with the British political consultancy firm Cambridge Analytica.

After the Cambridge Analytica data scandal, Facebook suspended Boston-based data analytics company Crimson Hexagon over concerns that it harvested users’ data.
