Henderson was removed from his role in July 2016 amid growing dissatisfaction among shareholders over stalling growth. He was replaced by Bowcock, the group's finance chief, on an interim basis.
"Since his appointment as Interim CEO last July, Philip has driven the business forward at real pace and we have seen important progress across our Online, Retail and international businesses over that time," said group chairman Gareth Davis.
"Our recent results show that William Hill is now in a stronger position and Philip has outlined a clear plan to continue that momentum into the future."
The process of finding a new CEO was incredibly tortuous for the group, with reports of disagreements over who should succeed Henderson at the helm. According to sources cited by the Financial Times, Parvus Asset Management, William Hill's largest shareholder, had raised doubts over Bowcock's suitability for the role.
Bowcock
said: "I am proud to be chosen to lead William Hill, a business that
millions of customers trust and a brand that is synonymous with betting. During
my time at the helm, I have had the opportunity to lead a passionate, talented
and committed team and we have made considerable operational progress in recent
months.”
"The team and I are excited by the opportunity to keep improving our position
in all our key markets while delivering a great experience for our
customers," Bowcock added.
