Utermann joined
Mercury Asset Management in 1989, becoming head of pan-European and subsequently global equities over the course of his 13 years there. He left
Merrill Lynch Investment Managers (as Mercury became known a couple of years after its 1997 acquisition by Merrill Lynch) in 2002. In 2002, Utermann joined
Allianz to become its global CIO for equities. When Allianz's asset management division restructured in 2011, Utermann became Global CIO and co-head of Allianz Global Investors alongside
Elizabeth Corley as CEO; in a 2012 media story headlined "Mercury keeps rising at AllianzGI", the journalist noted that the co-head structure followed "the mixed gender trail blazed by
Carol Galley and
Stephen Zimmerman, former co-heads of Mercury Asset Management, where both Utermann and Corley honed their craft." Utermann was sole CEO since 2016, when Corley moved into a non-executive role within the firm. During his time in charge of Allianz Global Investors, Utermann expanded its investment offering further into bonds (for instance with the acquisition of Rogge Global Partners in early 2016) and creating a dedicated
Alternative investments function. Utermann retired as CEO of AllianzGI on 31 December 2019 and served as advisor to the firm until 30.6.2020. Utermann was elected as Chairman of the Board of Directors of Vontobel Holding AG in April 2022, having been appointed to the Board as a
Non-Executive Director in April 2021. ==Active investing==
