“Over the last few years, it has become increasingly difficult to apply our rigorous bottom-up investment process to rapidly shifting market conditions and an evolving market structure,” Sandler wrote in a letter seen by Bloomberg. “We believe that in recent years we have fallen short of our very high standard and your expectations.”

His fund has posted disappointing returns and the high costs of retaining talent and building out necessary infrastructure made continuing the firm too difficult, Sandler wrote. 

A representative for the firm declined to comment.

Eminence has suspended redemptions in order to facilitate an orderly wind down, Sandler said in the letter. Cash distributions of at least 75% of each Eminence fund’s net asset value are expected by mid-to-late June. 

“I am tremendously proud of the Eminence team for the business and culture we built and the quality of our investor base,” Sandler wrote. “The Firm has been far more than a professional endeavor to me. It has been a defining part of my life.”

Eminence manages about $7 billion.
