Nick Waters has left Dentsu Aegis Network after a decade at the agency, most recently serving as its executive chairman for the UK and Ireland.
Waters joined the group in 2010 as chief executive of Aegis Media Asia Pacific and, following the acquisition by Dentsu, became CEO of the region.
He returned to the UK earlier this year as chairman to support Euan Jarvie in his first year as the region’s chief executive.
“I’d like to take this opportunity to thank Nick for playing a pivotal role in the evolution of the UK&I business this year and for his partnership,” Jarvie said of Waters' departure.
“Together, we’ve made great strides in reshaping and evolving the business to set ourselves up for even greater success. We are building momentum and ambition across our network as a result and we will be accelerating this as we move into 2020.”
Waters said it felt like a “natural time to move on” and will leave the business at the end of the year.
There are no immediate plans to replace his role.
It marks another change in senior leadership at the advertising group following the promotion of Isobar global chief executive Jean Lin to chief executive of Dentsu Aegis Network Creative, following the exit of global chief executive of creative, Dick van Motman.
In June, chief strategy officer Matthew Hook also announced his departure after 17 years.
In Singapore, the company has made a number of redundancies over the past year after bringing in a new management structure for APAC in March. The likes Sunil Yadav, the former president for APAC at Amplifi, Kristian Barnes, former chief client officer, and Sean O’Brien, media chairman at DAN and former chief executive of Posterscope and MKTG, all departed after the restructure.
Phil Teeman, the former chief executive of DAN Singapore and South East Asia, Rob Hughes, the former DAN North Asia chief executive, and DAN China chief executive Susana Tsui also all left the agency in quick succession.
