Planned succession follows appointment of William Davies as Global CIO

BOSTON, Massachusetts, July 15, 2021 (BUSINESS WIRE) -- Columbia Threadneedle Investments today announced that, as part of a planned transition, Melda Mergen, Deputy Global Head of Equities, will succeed William Davies as Global Head of Equities on October 1, 2021. As previously announced, Mr. Davies will assume the role of Global Chief Investment Officer in January 2022 when current Global CIO Colin Moore retires from the firm. Ms. Mergen will continue to report to Mr. Davies when she assumes her new role.

Ms. Mergen (pictured) has made significant contributions to the firm in research, portfolio management and investment oversight roles since joining a predecessor firm to Columbia Threadneedle in 1999. She assumed her current role as Deputy Global Head of Equities, overseeing the U.S. equity investment team, in 2017, having previously served as Head of U.S. Equities and prior to that leading the investment oversight team. In her new role, Ms. Mergen will lead Columbia Threadneedle's equity investment teams across the U.S., EMEA and APAC. 

In addition to her leadership responsibilities, Ms. Mergen co-manages several large-cap equity strategies. She will continue to manage portfolios when she assumes her new role and there is no change to the investment process that underpins these strategies. Ms. Mergen is also co-chair of the firm's North America Diversity & Inclusion Group.

Mr. Davies said: 

"Melda is a highly respected investor and proven leader with a strong track record in delivering consistently competitive investment performance and research-driven solutions for our clients. We have worked together for many years and I am confident that the leadership and continuity she brings to the role will serve our clients well."
