• Twitter said it had 187 million monetizable daily active users (mDAU) during the third quarter;
• Ad revenue in the third quarter grew 15% to $808 million from the same period a year ago, surpassing estimates of $645.95 million.

Twitter on Thursday widely beat analyst expectations for quarterly revenue as ad sales rose with the return of sports and other events, but it added fewer users than Wall Street had expected.

The company said it expected revenue trends could continue or even improve in the current quarter, but cautioned that it was hard to predict how advertisers would react as the U.S. presidential election nears on Nov. 3, and that there could be a pause in ad spending.

The San Francisco-based social media company said it had 187 million monetizable daily active users (mDAU) during the third quarter, missing consensus analyst expectations of 195.2 million users, according to IBES data from Refinitiv. The figure stood at 186 million in the previous quarter.

Twitter said total revenue grew 14% year-over-year to $936 million during the quarter ended Sept. 30, beating analyst estimates of $777.15 million.

The growth was helped by updated advertising formats, improved ad measurement and the return of events that had been paused due to the pandemic, said Twitter Chief Financial Officer Ned Segal in the earnings release.

Advertisers are often drawn to Twitter because the platform allows them to appear next to major cultural moments or conversation topics such as sports events.
