Walt Disney is expanding his search for two new Chief Executives to run the media company. Bob Iger, the company’s current CEO and Chairman is due for retirement while its Chief operating officer, Tom Staggs is stepping down May 6.

Reuters reported that Staggs exit is not unconnected to the media company's board decision of looking beyond him for the top job.

A source with knowledge of the situation said Staggs, 55, had learnt he was not guaranteed the CEO job and that the board was going to broaden its search for a new leader. Staggs and the company mutually decided he should step down, said the source, who requested anonymity.

Disney, which operates television networks, theme parks and a movie studio, said in a statement that the board aimed to evaluate a "robust slate of candidates."

Iger has led Disney to record profits and executed successful acquisitions of Pixar, Marvel Entertainment and "Star Wars" producer Lucasfilm Ltd. But he recently acknowledged subscriber declines at Disney's sports network ESPN, raising concern among investors about how the channel would adapt to online streaming technology that is rapidly drawing viewers away from traditional TV.

Disney's board may have decided the company needs a new CEO with more experience in technology to navigate that change, Edward Jones analyst Robin Diedrich said in an interview.

"How do you transition to that five, 10, 15 years out?" said Diedrich, who recommends buying Disney shares. "There may be a need there for someone who has more experience with that consumer trend that is certainly here to stay."

Iger, 65, has insisted that he would retire from Disney in June 2018, though the board previously convinced him to extend his contract twice after he announced plans to leave.

Disney's shares fell 1.5 percent to $97.18 in after-hours trading on Monday.

The company promoted Staggs to COO in February 2015 from his post as head of Disney's theme parks and resorts and following a previous stint as chief financial officer. While Disney never referred to him as the heir apparent, his move into the No. 2 job put him in the lead to ascend to CEO. One of his biggest projects was the building of Shanghai Disneyland, which is scheduled to open in June.

Staggs will remain employed by Disney as a special adviser to Iger through the company's fiscal year, which goes through September, Disney said. He joined Disney in 1990 after working in investment banking at Morgan Stanley & Co.
