 Activist shareholder Ancora Holdings Group LLC on Thursday urged the board of Kohls Corp. KSS, -1.45 to replace its chairman Peter Boneparth and chief executive Michelle Gass with a leader with turnaround experience. In a letter to the board made public, Ancora said the retailers botched strategic review, credit downgrade, dramatic decline in sales, elevated costs and poorly received standalone plan have placed it on a dangerous trajectory.
