  • Significant increase in AUM for Mesirow Equity Management
  • Growth reflects strong performance, differentiated strategies and client-centric approach
  • AUM advanced over 25% so far in 2023

CHICAGO, September 26, 2023 – Mesirow, an independent employee-owned financial services firm, announced that Mesirow Equity Management (“MEM”) has surpassed $1 billion in assets under management (“AUM”) as of August 31, 2023.

Led by Kathryn Vorisek, Head of Equity Management, Portfolio Manager, and Leo Harmon, Chief Investment Officer, Portfolio Manager, MEM focuses exclusively on managing small cap and small-mid cap portfolios and has historically delivered attractive risk adjusted returns with lower downside risk relative to the market and their peer group.

In 2023, the team’s AUM advanced more than 25%, reflecting marketplace interest in the team’s differentiated approach and their ability to navigate volatile and uncertain macroeconomic conditions. While the team emphasizes risk management, they also see opportunities in small-cap companies to potentially deliver competitive results.

"Surpassing $1 billion in AUM is a testament to the dedication of our entire team as well as the trust clients place in Mesirow. We are proud to serve our clients’ financial needs and value our long-term partnerships with them,” said Kathryn Vorisek.
