                  Jack in the Box Inc. Reports Third
Quarter Earnings; Raises Fiscal 2007 Earnings Forecast; Plans 2-For-1
                             Stock Split


    SAN DIEGO--(BUSINESS WIRE)--Aug. 8, 2007--Jack in the Box Inc.
(NYSE: JBX) today reported earnings of $34.7 million, or $1.08 per
diluted share, for the quarter ended July 8, 2007, compared with $27.8
million, or 77 cents per diluted share, for the same quarter a year
ago. Year-to-date net earnings increased to $99.3 million, or $2.90
per diluted share, versus $74.9 million, or $2.09 per diluted share,
for the same period last year.

    Third quarter earnings exceeded by 19 cents the high end of the
range previously forecast by the company and analysts' First Call
consensus estimate - 89 cents - due primarily to the following, in
approximate amounts:

    --  +8 cents from higher sales and franchise revenues, and good
        expense controls, partially offset by lower restaurant
        operating margin due to higher food costs.

    --  +7 cents primarily from an insurance recovery.

    --  +4 cents due to higher gains from the planned refranchising of
        22 Jack in the Box(R) restaurants, which had
        higher-than-average cash flows.

    "Our success in executing the company's strategic plan has Jack in
the Box Inc. well on its way to another record year of earnings," said
Linda A. Lang, chairman and chief executive officer. "We're growing
our business, expanding our franchise operations, and, through the
holistic reinvention of the Jack in the Box brand, broadening our
appeal and becoming a preferred dining destination for our guests."

    Third quarter financial highlights

    Same-store sales at Jack in the Box company restaurants were up
7.4 percent in the third quarter, with an increase in both average
check and transactions, on top of a year-ago increase of 2.9 percent.
Year to date, same-store sales were up 6.4 percent on top of a 4.3
percent increase for the same period last year. System same-store
sales at Qdoba Mexican Grill(R) increased 5.0 percent in the third
quarter on top of a 6.0 percent increase in the third quarter of 2006.
Year to date, same-store sales were up 4.2 percent at Qdoba on top of
a 6.5 percent increase for the first three quarters of fiscal 2006.

    Restaurant operating margin was 17.4 percent of sales in the third
quarter compared with the company's internal forecast of 17.9 percent
and 18.7 percent a year ago, due primarily to higher commodity costs
offset by fixed cost leverage from higher sales in 2007, profit
improvement program initiatives and labor efficiencies. Year to date,
restaurant operating margin improved to 18.1 percent of sales versus
17.4 percent for the same period a year ago, with the 70-basis-point
improvement due primarily to fixed cost leverage from higher sales in
2007, profit improvement program initiatives, and lower costs for
utilities, partially offset by higher food costs.

    Beef costs for the quarter were up approximately 9 percent versus
prior year. Egg and cheese costs were also up substantially for the
quarter. The company expects higher food costs to continue for the
balance of the calendar year, with some softening in beef prices
versus the third quarter.

    SG&A expense rate in the third quarter improved to 9.1 percent of
revenues compared with 10.6 percent last year, due primarily to
leverage from higher sales and franchise revenues, lower pension
expense, an insurance recovery, profit improvement program initiatives
and the impact of the company's refranchising strategy.

    Jack in the Box opened 10 new company and franchised restaurants
in the third quarter, the same as last year, and Qdoba opened 18
company and franchised restaurants versus 14 last year. In the
quarter, Qdoba purchased nine franchised restaurants in western
Michigan, which it plans to develop as a company market. Year to date,
Jack in the Box added 30 new restaurants, including 11 franchised
locations, versus 19 new restaurants last year, which included 4
franchised locations. Qdoba added 60 new company and franchised
restaurants in the first three quarters of fiscal 2007 compared with
50 a year ago. At July 8, the company's system total comprised 2,107
company and franchised Jack in the Box restaurants, including 58 with
Quick Stuff(R) convenience stores, and 371 company and franchised
Qdoba restaurants.

    Gains on sale of company-operated restaurants were $12.6 million
in the third quarter, resulting from the sale of 22 Jack in the Box
company restaurants to franchisees. In the third quarter of fiscal
2006, gains on sale of company-operated restaurants totaled $5.6
million, resulting from the sale of 17 Jack in the Box company
restaurants to franchisees. The difference in average gains is related
to the specific sales and cash flows of restaurants sold.

    The effective tax rate in the third quarter was 35.3 percent
versus 34.1 percent a year ago, with the lower rate in 2006 due
primarily to specific tax-planning initiatives and tax credits.

    Capital expenditures were $38.3 million in the quarter compared
with $35.0 million in fiscal 2006, with the increase due primarily to
investment in the Jack in the Box re-image program.

    Franchising and new market expansion

    Included among the 22 Jack in the Box restaurants refranchised in
the third quarter was a transaction involving 14 locations in Houston,
which was previously an entirely company-operated market.

    The company has signed franchise development agreements to expand
the Jack in the Box brand into three new contiguous markets:
Albuquerque, N.M., Midland/Odessa, Texas, and Abilene/San Angelo,
Texas. The first restaurants in these new markets are scheduled to
open in 2008.

    Additionally, construction is currently underway on
company-operated Jack in the Box restaurants in two new contiguous
markets: Denver, Colo., and Corpus Christi, Texas. The first
restaurants in these new markets are scheduled to open in the next few
months.

    Third quarter initiatives

    --  In the third quarter, Jack in the Box became the first major
        quick-serve chain to offer an all-sirloin hamburger patty,
        which weighs in at nearly one-third of a pound after cooking.
        The 100% Sirloin Burger is served on a toasted bakery-style
        bun with peppercorn mayo, pickle strips, lettuce and tomato.
        Guests have the opportunity to customize their burger with
        American, cheddar or Swiss cheese, grilled or red onions, and
        bacon.

    --  In June, Jack in the Box enhanced its entire line of entree
        salads with a new blend of mostly romaine lettuce and spring
        mix and another customization option - a choice of grilled or
        crispy chicken strips. Jack in the Box also added a BBQ Ranch
        Chicken Salad, which is topped with real cheddar cheese, fresh
        cucumber slices and red onion rings, and served with crunchy
        barbecue tortilla strips, barbecue sauce and ranch dressing on
        the side.

    --  Other menu additions include the following: a Blackberry
        Shake, made with real vanilla ice cream blended with pieces of
        real blackberries and served with creamy whipped topping and a
        maraschino cherry; and a Chocolate Overload Cake, a
        bundt-style dessert made from dark European and double-dutch
        cocoa mixed with bittersweet chocolate chips and topped with a
        drizzle of chocolate butter cream frosting.

    Upgrading the menu with innovative products featuring high-quality
ingredients, along with improving the guest experience through service
initiatives and enhancements to the restaurant environment, is a
primary focus of the company's strategy to holistically reinvent the
Jack in the Box brand. Through the first three quarters of fiscal
2007, Jack in the Box re-imaged 118 restaurants with a comprehensive
program that includes a complete redesign of the dining room and
common areas. Interior finishes include ceramic tile floors, a mix of
seating styles ranging from booths and bars to high-top round tables,
decorative pendant lighting, and graphics and wall collages. The
program, which is expected to be rolled out to 150-200 restaurants in
fiscal 2007 and to the entire Jack in the Box system in 4-5 years,
also includes music, uniforms and packaging, along with new paint
schemes, landscaping and other exterior enhancements.

    "We're continuing to see positive sales trends and higher guest
satisfaction ratings in markets that have been re-imaged," Lang said.

    2-for-1 stock split

    In a separate news release issued yesterday, Jack in the Box Inc.
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 number of shares of
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,
satisfy the company's obligations under its benefit plans, and
accommodate other corporate purposes. The company will hold a special
meeting of stockholders, which is tentatively set for Sept. 21, 2007,
to vote on the charter amendment to increase the number of authorized
shares of common stock.

    Fiscal year 2007 guidance update (in approximate amounts)

    Jack in the Box Inc. today updated its earnings guidance and
certain underlying assumptions for fiscal year 2007:

        company-operated restaurants.

    --  3.0-5.0 percent same-store sales increase at Qdoba system
        restaurants.

    --  $38-40 million in gains from the sale of 75-80 restaurants to
        franchisees.

    --  Tax rate of approximately 36 percent.

    --  45-50 new company and franchise-operated Jack in the Box
        restaurants.

    --  80-90 new company and franchise-operated Qdoba restaurants.

    --  $170-175 million in capital expenditures, including investment
        costs related to the Jack in the Box restaurant re-image
        program, kitchen enhancements, and Qdoba's third-quarter
        acquisition of nine franchised restaurants.

    Fourth quarter guidance (in approximate amounts)

    Jack in the Box Inc. also today announced the following guidance
for the fourth quarter of 2007:

    --  72-76 cents per diluted share in earnings.

    --  4.0-4.5 percent same-store sales increase at Jack in the Box
        company-operated restaurants, on top of a 5.9 percent increase
        in 2006.

    Fourth quarter initiatives

    Among the company's fourth-quarter marketing events are the
following:

    --  Last month, Jack in the Box introduced Real Ice Cream Floats,
        delightfully refreshing beverages featuring vanilla ice cream
        mixed with a choice of soda, including Barq's(R) Root Beer, Dr
        Pepper(R) and Fanta(R) orange. Beginning August 13, Jack in
        the Box will launch a limited-time promotion to "Float Your
        Combo," whereby guests can upgrade their combo meal beverages
        with a Real Ice Cream Float for a slight charge.

    --  Next week, the company will enhance its breakfast menu with a
        Sirloin Steak & Egg Burrito, which will feature a flour
        tortilla stuffed with 100% sirloin steak, shredded cheddar and
        pepper jack cheeses, scrambled eggs and hash browns, topped
        with a chipotle sauce and served with a side of fire-roasted
        salsa.
