Last month, Jack in the Box reported fourth-quarter earnings fell to $18.3 million, or 68 cents per diluted share, from $31.3 million, or $1.05 per share a year earlier. For fiscal 2018, the company reported earnings fell to $104.3 million, or $3.62 per diluted share, from $128.6 million, or $4.16 per diluted share in fiscal 2017. "We experienced a slowdown in September along with the rest of the category. The competitive environment remains extremely aggressive, but we continue to avoid deep discounting, which we believe is not in the best interests of the long-term health of the brand," Comma said at the time.

At the same time, Jack in the Box has plans to downsize its San Diego headquarters with the sale of its main corporate building, according to a regulatory filing made this month.
Chain spokesman Brian Luscomb said the company does not comment on rumors and speculation. However, he did confirm the chain’s intent to sell its 150,000 square foot main office and relocate to a smaller building next door. Turns out that smaller building is up for sale so soon one can assume corporate will be done at new owners assuming someone wants to buy this dying company - Perhaps Sears.
