Kurt Winrich, co-CEO and portfolio manager for WCM Investment Management, will retire at the end of the year, a spokesman confirmed in an email.
Co-CEO Paul Black will remain president and become sole CEO.
Mr. Winrich's position on the two investment strategies he serves as portfolio manager for — focused growth international and quality global growth — will not be replaced. Both strategies will continue to be managed by the remainder of the team: Mr. Black, Peter Hunkel, Michael Trigg and Sanjay Ayer.
The remainder of his day-to-day responsibilities will be handed off to successors, which WCM has already selected and trained, by the end of the year.
Mr. Winrich will remain chairman after he retires. He will also remain an equity owner at WCM and maintain his current stake, which was not disclosed.
WCM managed $101 billion as of July 31.
