Pizza Hut's parent company plans to close about 500 of the chain's dine-in locations as part of a company push to focus on delivery, Yum! Brands CEO Greg Creed said in an earnings call last week.

On the earnings call, which was delivered Aug. 1, Creed said the company wants to "accelerate the transition" of Pizza Hut restaurants from sit-down, dine-in restaurants to storefronts that only offer delivery or carry out.

On the call, Creed said the company has about 6,100 restaurant-style locations throughout the country and 1,350 "express units."

It's not clear which locations would close and when, but Creed noted that "lower volume" restaurants would be likely affected by the change.
