Exclusive-Third Point won’t run proxy fight at CoStar, exits position, letter says By Reuters
Billionaire investor Daniel Loeb's hedge fund Third Point has decided not to pursue a proxy fight at real estate data company CoStar Group and has sold its entire stake. The fund, which had previously signaled a board challenge to pressure CoStar into focusing on its core business, concluded that its original thesis no longer held true due to the company's continued investment in residential operations despite plummeting stock prices. This decision comes after Third Point and D.E. Shaw had previously reached settlements with CoStar in 2025 regarding board changes.
