San Diego-based fast food chain Jack in the Box Inc. has begun searching for a successor to chief financial officer, Jerry Rebel, who plans to retire from the role in 2018, the company announced.

Jack in the Box (NASDAQ: JACK) said Rebel would remain with the company until a replacement is hired.

Rebel joined the company in 2003. He was named CFO in January 2005.

During his tenure, the company’s common stock has appreciated by more than 450 percent, Jack in the Box said.

The company’s stock fell sharply in February, however, after Jack in the Box reported lower than expected first-quarter earnings.

Jack in the Box operates and franchises more than 2,200 Jack in the Box restaurants and more than 700 Qdoba Mexican Eats restaurants.
