Chicago-based Calamos Investments has completed the firm's acquisition of Timpani Capital Management, a boutique small- and mid-cap investment manager based in Milwaukee.

The previously announced transaction has closed following the fulfilment of regulatory and closing conditions, including mutual fund shareholder approvals. Timpani co-founder Brandon M. Nelson and his investment team joined Calamos Investments upon the transaction's close and will remain based in Milwaukee.

Calamos announced the launch of Calamos Timpani Small Cap Growth Fund, which will retain its Timpani investment team and track record of more than eight years, alongside the Calamos Timpani Small Cap Growth Strategy, a separately managed account offering with a track record of more than 11 years.

“With more than 30 percent growth in [assets under management] since 2017, our strategic growth plan continues to show results, centering on innovative active management and a commitment to deliver results for clients,” Calmos CEO John Koudounis said in a statement. “Our growth is founded on investors' recognizing the potential benefits of active management in navigating difficult markets and, as the Calamos Timpani Small Cap Growth Fund's track record bears out, identifying opportunities for outperformance.”

Calamos Investments is a diversified global investment firm offering innovative investment strategies including alternatives, multi-asset, convertible, fixed income, and equity.
