In a call to analysts following the release of Q3 results, Linda Lang, Jack in the Box's chair and CEO, thanked Graham fro her "countless contributions," including oversight of the chain's advertising campaigns and product development, "which have contributed to our high level of brand awareness, as well as an impressive record of sales growth," Lang said.

Company officials said the chain is not looking for a replacement to fill the CMO role, but marketing responsibilities will be handled by internal talent.

Graham has "put together a very strong team, an experienced team, and she'll be assisting us during the transition," Lang added.

Under Graham, Jack in the Box has focused marketing efforts on the iconic and edgy character Jack, with his oversized ping pong ball-head and pointy yellow hat, perched at a jaunty angle.
