Three top executives at Zale, including its CEO, have left the jeweler as it struggles with sagging sales and angry vendors.

Neal Goldberg, who joined the company in 2007, will be replaced as CEO on an interim basis by President Theo Killion. Chief Stores Officer William Acevedo and Chief Merchandising Officer Mary Kwan have also left the company.

Zale’s same-store sales dropped 12 percent in November and December, although the chain said “pricing and promotional discipline” helped margins. Shares fell 14 percent to $2.75 in after-hours trading.
