To Our Clients and Customers:

We are happy to announce that on June 1, Cowen completed its acquisition of Convergex Group, LLC.  Effective today, Convergex has been renamed Cowen Execution Services LLC and Convergex Limited, its London-based brokerage, has been renamed Cowen Execution Services Limited.

Headquartered in New York, Convergex is a leading agency-focused global brokerage and trading related services provider with a deep client base of 2,500 hedge funds, asset managers, broker-dealers, trusts and exchanges. Business units include equity sales and electronic trading, commission management, plan sponsor services, prime services and global clearing.

By acquiring Convergex, we see tremendous opportunities to better serve you. We have enhanced an area where Cowen is already performing well and established our position as the leading independent trading partner in equities with high quality research and best-in-class global execution capabilities.

The addition of Convergex’s state of the art global platform and its access to over 90% of the global equities market will provide Cowen a meaningful opportunity to scale our trading business and to significantly bolster our capabilities in prime services, algorithmic and electronic trading, as well as enable us to enter the clearing, commission management and plan sponsor businesses.
