Exhibit 99.1

    Jack in the Box Inc. Announces 2-For-1 Stock Split, Subject to
     Stockholder Approval of Increase in Authorized Common Stock

    SAN DIEGO--(BUSINESS WIRE)--Aug. 7, 2007--Jack in the Box Inc.
(NYSE: JBX) today announced that its board of directors has approved a
2-for-1 split of the company's common stock, to be effected in the
form of a special 100 percent stock dividend. The split is subject to
stockholder approval of a charter amendment to increase the company's
authorized common stock. The proposed increase in authorized common
stock would provide sufficient authorized and unissued shares of
common stock to ensure consummation of the split and satisfy the
company's obligations under its benefit plans and to accommodate other
corporate purposes.

    Jack in the Box Inc. also today announced that it will hold a
special meeting of stockholders, tentatively scheduled for Sept. 21,
2007, to vote on such increase in the number of authorized shares of
common stock. The record date for the special meeting will be Aug. 14,
2007.

    "The company's strong performance over the past few years has
contributed to a significant increase in the price of Jack in the
Box(R) common stock and delivered great returns to our stockholders,"
said Linda A. Lang, chairman and chief executive officer. "We remain
optimistic in the company's continued growth potential and view the
stock split as an opportunity to price the stock in a more attractive
range for investors. And by increasing the number of shares available
to trade, we believe the stock split can also increase the liquidity
of the company's common stock."

    Subject to receiving stockholder approval for an increase in
authorized common stock, the record date for the stock split will be
Oct. 2, 2007, with the distribution date expected to be on or about
Oct. 15, 2007. If stockholders approve the increase in the number of
authorized shares, stockholders of record on the record date will
receive on the distribution date one additional share of the company's
common stock for each share owned. As proposed, the stock split would
increase the number of outstanding shares of common stock from
approximately 31.4 million to approximately 63 million shares.
