Warner Bros. Discovery said Thursday its streaming platform Max added 7.2 million global subscribers in the third quarter. It marked the biggest quarterly growth for the streaming platform since its inception. Max now had 110.5 million subscribers as of Sept.

"Your company is trading like a company that's declining in earnings," said Ben Swinburne, a media-industry analyst with Morgan Stanley during a call between Warner Bros. Discover

Warner Bros. Discovery's Max serves fewer ads per hour compared to other streaming platforms.

Warner Bros Discovery posted a surprise third-quarter profit on Thursday as the Paris Olympics powered streaming subscriber growth and cable revenue, making up for a lack of major box office hits from its studio.

The media and entertainment company posted third-quarter earnings of 5 cents a share, when analysts had been expecting a loss.
