Cosio (pictured) was previously managing director for intermediaries in the UK, southern Europe and the Middle East and North Africa at AB.
Axa-owned AB confirmed it is currently recruiting for his replacement and will make an announcement in due course.
At Neuberger, Cosio will be responsible for Emea and Latin America.
In a press release announcing his appointment, Cosio said the asset manager is known for its activities in liquid and illiquid markets and its “close long-term client partnerships”.
He will report to head of Emea and Latin America Dik van Lomwel, who said the firm was looking to “deepen the dialogue” with global and regional financial institutions. The company has opened 12 local offices across the region over the last decade.
Van Lomwel said: “Our Ucits platform has grown to nearly 50 funds across traditional and alternative asset classes, from fewer than 10 funds, in the same time period, with total assets under management in the region growing from $3bn (£2.4bn) to $44bn. Jose will add real impetus to this growth trajectory.”
Cosio has previously worked at Wachovia Securities and Old Mutual Bermuda.
