When Kohl’s Corp. on Monday announced it was getting a new chief executive next year, investors got suspicious. On Tuesday, the department-store chain confirmed those suspicions, reporting results that missed expectations and sending shares sharply lower.

Kohl's CEO Tom Kingsbury will step down after less than two years at the helm, paving the way for former Walmart executive Ashley Buchanan to take on the role as the department store chain looks to execute a turnaround.

Kohl’s surprise CEO departure announcement a day before its quarterly results will play on the minds of investors, who were looking out for a positive forecast from the struggling department store chain ahead of the key holiday shopping season.
