The club announced in September 2024 that Darren would be stepping down from his position for health reasons but would continue to lead Newcastle United's executive team until a successor was appointed.
Following David's appointment, Darren will conduct a comprehensive handover process before bringing his three successful years at St. James' Park to a close.
Darren arrived at St. James' Park in August 2022, just ten months after the club's change in ownership.
He played a vital leadership role in a period of significant progression on and off the pitch, culminating in Newcastle United winning its first major domestic trophy for 70 years in March 2025 and securing UEFA Champions League qualification in two of the last three seasons.
Darren said: "On behalf of my family and I, I want to extend my sincere thanks to everyone connected to this special football club for welcoming us into the Newcastle United family.
"To all supporters, staff, players, coaches and ownership, you have made my three years here so incredible and I'm immensely proud of what we have achieved together.
"I have made memories that will stay with me forever, and I'm also excited about what the future holds and the successes the club can go on to achieve.
"I want to warmly welcome David Hopkinson as the club’s new CEO. Newcastle United is in great hands, and I’d like to wish David and the executive team every success as the club continues on the next part of its exciting journey."
'Our very best wishes'
Newcastle United chairman, Yasir Al-Rumayyan, said: "Darren has played a vital role in the growth and success of Newcastle United in his three years as CEO.
"We thank him sincerely for his immense contribution to the club and extend our very best wishes to him and his family for the future. "
"I would like to personally thank Darren for his friendship. He will always be welcomed at St. James' Park."
Director Jamie Reuben added: "I want to thank Darren for his exceptional leadership during a period of positive change on and off the pitch.
"We are all sorry to see him leaving Newcastle United, but his health and his family must come first and he leaves with the best wishes of everyone connected with the club.
"Darren will always be part of our Newcastle United family and we wish him a full and speedy recovery."
Incoming CEO, David Hopkinson, commented: "I have known Darren for many years and he is a special person as well as an outstanding executive.
"The progress made by the club under his stewardship is hugely impressive. It's an honour for me to embark on the next step of the club's journey with ownership and the executive team.
"Darren has been incredibly supportive in our conversations and I look forward to working with him as we begin the transition of the CEO role."
