Teun Johnston takes the reigns at Artemis

Teun Johnston has been named CEO of Artemis Investment Management, effective April.

Artemis holds £28.5 billion in assets under management.

On future plans, Johnston said: “We will seek to further enhance Artemis’ strengths in ongoing collaboration with our supportive strategic partner, AMG, with a focus on broadening our client base internationally and diversifying our investment offering.”

He replaces senior partner Mark Murray as head of the company. Murray will retire in June.

Johnston has more than 30 years of industry experience, most recently serving as CEO of Man Group GLG, the company’s discretionary investment manager. He left the company during a reorganisation in January 2024, which also saw GLG combine with other investment teams.

Earlier in his career, Johnston spent two years at Oakley Capital as head of investments.
