Disney said in its fiscal Q1 earnings report on Tuesday that its new streaming service, Disney+, had 26.5 million paying subscribers during the quarter. CEO Bob Iger said on the company's earnings call that, by Monday, that number had climbed to 28.6 million subscribers.

The company announced in November that Disney+ had picked up 10 million subscribers within a day after it launched. Tuesday's report is the first subscriber update since then.

Iger told Julia Boorstin on CNBC's "Closing Bell" on Tuesday that "about 20%" of the 26.5 million subscribers came through a distribution partnership with Verizon that offered a free year of Disney+ to some Verizon customers. But there's no guarantee that customers who got Disney+ through free trials will resubscribe as paying customers once the trial is up.

Disney also did not update its guidance for the service. The company previously forecast between 60 million and 90 million subscribers by the end of its 2024 fiscal year.

Much of the service's subscriber growth was likely driven by its flagship show, "The Mandalorian," but the show's first season ended in December. Iger said on the company's conference call that "both conversion from free to pay and churn rate were better than we expected." Churn refers to the pace at which users sign up for and cancel subscriptions.
