CoStar Group has undergone significant changes in its leadership and legal battles. The company's chairman was ousted amid a hedge fund-driven board shakeup. Concurrently, CoStar agreed to dismiss a trade secrets lawsuit against it, which involved a competitor, News Corp. This lawsuit was characterized by CoStar's CEO as a 'nasty PR stunt' aimed at damaging the company's reputation. Despite the dismissal, the war of words between CoStar and its competitors continues, as the company also reshapes its board to sharpen its focus on success.
