Exhibit 99.1

         Jack in the Box Inc. Reports Third Quarter Results;
                    Raises FY06 Earnings Forecast;
            Announces Agreement to Franchise Hawaii Market

    SAN DIEGO--(BUSINESS WIRE)--Aug. 8, 2006--Jack in the Box Inc.
(NYSE:JBX) today reported that net earnings increased to $27.8
million, or 77 cents per diluted share, in the third quarter ended
July 9, 2006, compared with $23.9 million, or 66 cents per diluted
share, in the same quarter a year ago. Results exceeded the company's
guidance of 65-67 cents per diluted share and analysts' First Call
consensus estimate of 66 cents. Year to date, net earnings totaled
$74.9 million, or $2.09 per diluted share, compared with $70.0
million, or $1.89 per diluted share, for the first three quarters of
fiscal 2005.
    "We're continuing to make progress in reinventing the Jack in the
Box(R) brand," said Linda A. Lang, chairman and chief executive
officer. "Those efforts are reflected in the company's strong third
quarter results and our optimism for continued growth in sales and
earnings. The pending sale of our company restaurants in Hawaii
underscores the progress we're making in our strategic initiative to
increase franchising. Franchising will help expand the Jack in the Box
brand in new and existing markets, and can generate higher returns and
margins for the company."
    As required by Statement of Financial Accounting Standards (SFAS)
No. 123R, fiscal 2006 results include the effect of expensing stock
options. Fiscal 2005 results did not include the effect of expensing
of stock options. The following table shows a 22 percent increase in
comparable third-quarter diluted EPS, adjusting for the pro forma
effect of stock option expense in fiscal 2005:

    statements of earnings commencing with the adoption of SFAS 123R
    in the first quarter of fiscal 2006.

    Third quarter financial highlights

    Earnings per diluted share exceeded by 11 cents the midpoint of
the range previously forecast by the company. Approximately 8 cents of
this improvement versus guidance was due primarily to higher
restaurant operating margin resulting from lower costs related to
commodities and workers' compensation insurance, along with profit
improvement program initiatives and lower SG&A expense. The remaining
3 cents of the improvement was due to a lower tax rate resulting from
tax planning initiatives and tax credits.
    Same-store sales at Jack in the Box company restaurants increased
2.9 percent in the third quarter, on top of a 2.8 percent increase in
the third quarter of 2005. The improvement was slightly lower than the
range previously forecast, with an increase in average check partially
offset by slightly lower transactions. Year to date, Jack in the Box
same-store sales increased 4.3 percent on top of a 2.7 percent
increase for the same period in 2005, with an increase in both average
check and transactions. For the third quarter, system same-store sales
at Qdoba Mexican Grill(R) increased 6.0 percent on top of a 10.3
percent increase in the third quarter of 2005. Year to date, system
same-store sales at Qdoba increased 6.5 percent on top of a 12.3
percent increase for the same period last year. Qdoba continued to be
accretive to earnings for the quarter.
    "Qdoba continues to perform well and now has 28 consecutive
quarters -- or seven years -- of comparable sales growth," Lang said.
"I'd like to congratulate Qdoba's CEO and President Gary Beisler and
his team on two major accomplishments: In July, Qdoba celebrated the
opening of its 300th location, in Bloomington, Ind., and Nation's
Restaurant News selected Gary as one of only six 2006 Golden Chain
award winners."
    Restaurant operating margin increased to 18.7 percent of sales in
the third quarter compared with 18.0-18.2 percent forecast and 17.2
percent a year ago, with the improvement versus 2005 due primarily to
lower commodity costs -- principally beef, cheese and pork -- and
profit improvement program initiatives, partially offset by higher
utility costs. Beef costs were down approximately 11 percent versus
last year.
    SG&A expense rate, including an approximate 20-basis-point
increase from the expensing of stock options, was 10.5 percent of
revenues in the third quarter compared with 10.6 percent in 2005,
which did not include stock option expense.
    Ten company and franchised Jack in the Box restaurants opened in
the third quarter, along with 3 new Quick Stuff(R) convenience stores,
as forecast, compared with 10 new restaurants, including 4 Quick Stuff
sites, opened in the same quarter a year ago. Qdoba opened 14 company
and franchised restaurants during the third quarter, as forecast,
compared with 15 locations opened in the same quarter a year ago. At
July 9, the company's system total included 2,065 company and
franchised Jack in the Box restaurants, including 50 with Quick Stuff
convenience stores, and 298 company and franchised Qdoba restaurants.
    Gains on the sale of company-operated restaurants and other
revenues totaled $7.6 million in the third quarter, as forecast,
primarily from the sale of 17 Jack in the Box company restaurants to
franchisees, compared with approximately $6.4 million a year ago,
primarily from the sale of 20 such restaurants to franchisees. The
increase in average gains this year related to the specific sales and
cash flows of restaurants sold.
    The effective tax rate for the quarter was 34.1 percent, versus
37.0-37.5 percent forecast and 31.0 percent a year ago, with the
decrease versus forecast due to tax-planning initiatives and tax
credits. The tax rate in 2005 was lower due to the resolution of a
prior year's tax matter and tax-planning initiatives.
    Capital expenditures, including capital lease obligations, were
$42.2 million for the third quarter compared with $35-40 million
forecast and $26.8 million in fiscal 2005, with the increase due
primarily to investments associated with the company's restaurant
re-imaging program.

    Third quarter initiatives

    Several new products were introduced during the third quarter as
Jack in the Box continues to focus on menu innovation, upgraded
service execution and enhanced restaurant facilities, which are the
three major components of this holistic approach to reinvent the Jack
in the Box brand:

    --  Diner Melts, featuring either a single or double jumbo beef
        patty, grilled onions, two kinds of melted cheese, mayo-onion
        sauce and sweet mustard.

    --  Acapulco Chicken Salad, offering a blend of fresh romaine and
        spring mix lettuce topped with savory grilled chicken,
        shredded pepper jack cheese, grape tomatoes, cucumber slices
        and red onions served with a side of blue corn tortilla
        strips, a flavorful cilantro-lime dressing and lime wedges.

    --  Vanilla Malted Crunch Shake, made with real ice cream blended
        with malted crunch pieces.

    --  Jack's Fresh Fruit Cup, made by Del Monte(R), offering a
        7-ounce serving of cantaloupe, honeydew, pineapple and red
        grapes.

    --  Bottled spring water by Dannon(R).

    In the third quarter, the company began re-imaging Jack in the Box
restaurants in Seattle 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, such as
booths, bars and high-top round tables; decorative pendant lighting;
and graphics and wall collages. Other elements of the program include
music, uniforms, menu boards and packaging, along with new paint
schemes, landscaping and other exterior enhancements. The entire
market is expected to be re-imaged by fiscal year end.

    Agreement to franchise Hawaii market

    Jack in the Box Inc. also announced today that it has signed an
agreement to sell its company-operated Jack in the Box restaurants in
Hawaii to a new franchise operator, who has extensive experience
operating multiple quick-serve concepts in Hawaii. The sale of the 25
restaurants to Chris Scanlan, president of Scanlan Management, LLC, is
scheduled for completion late in the fourth quarter. Following
completion of the sale, which is expected to positively impact
earnings by approximately 20-24 cents per diluted share, the company's
Hawaii market will be entirely franchise operated. A development
agreement for new restaurants will be part of this transaction, which
is expected to be neutral to earnings in subsequent years.
    More than 27 percent of the Jack in the Box system is currently
franchised. Including the projected sale of the restaurants in Hawaii,
along with additional restaurants that the company expects to
franchise in the fourth quarter, nearly 29 percent of the Jack in the
Box system will be franchised at fiscal year end.

    Fiscal year 2006 guidance update

    Jack in the Box Inc. today increased its earnings guidance for
fiscal 2006. The company now expects to earn approximately $2.72 --
$2.74 per diluted share for the full year, which is up from its
previous forecast of approximately $2.60 -- $2.63 per diluted share
and compares with $2.48 per diluted share earned in fiscal 2005. The
new forecast for fiscal 2006 does not include the anticipated benefit
of 20-24 cents per diluted share from the expected sale of
company-operated restaurants in Hawaii, but it does include the effect
of expensing stock options, as required by SFAS 123R. Fiscal 2005
results did not include the expensing of stock options. The following
table compares guidance for fiscal year 2006 with 2005 comparable
results, assuming the pro forma effect of expensing stock options of
approximately 15 cents per diluted share (excluding the effect of
accelerated vesting of retiree's stock options) and a charge related
to canceling the test of JBX Grill(R) in the fourth quarter of fiscal
2005:

(2) Included in SG&A expense in the company's unaudited consolidated
    statements of earnings.

    Fiscal 2006 earnings guidance represents a 14-15 percent
improvement over comparable 2005 results. The primary assumptions on
which earnings guidance is based are as follows, in approximate
amounts:

    --  The opening of 40 company and franchised Jack in the Box
        restaurants, including 12 with new Quick Stuff convenience
        stores, as well as the opening of 75 company and franchised
        Qdoba restaurants.

    --  A 4.0-4.5 percent increase in same-store sales at Jack in the
        Box company restaurants, and a 6.0-7.0 percent system
        same-store sales increase at Qdoba.

    --  Restaurant operating margin at 17.4-17.6 percent of sales
        versus 16.9 percent in 2005, with the increase due primarily
        to lower commodity costs, profit improvement program
        initiatives, and fixed-cost leverage on same-store sales
        growth, partially offset by higher utility costs.

    --  Gains on the sale of company-operated restaurants and other
        revenues of $34-35 million, primarily related to the sale of
        57 Jack in the Box restaurants to franchisees, excluding the
        pending Hawaii transaction.

    --  An effective tax rate of 36-36.5 percent.

    --  Capital expenditures, including capital lease obligations, of
        $150 million compared with $124 million in 2005, with the
        increase due primarily to investments associated with the
        planned re-imaging of approximately 150 Jack in the Box
        restaurants in 2006.

    Fourth quarter 2006 guidance

    The company also today provided earnings guidance for the fourth
quarter ending Oct. 1, 2006, of approximately 64-66 cents per diluted
share versus 59 cents per diluted share in the prior year. The
quarter's guidance does not include the anticipated benefit of 20-24
cents per diluted share from the expected sale of company-operated
restaurants in Hawaii, but it does include the effect of expensing
stock options, as required by SFAS 123R. Fourth-quarter fiscal 2005
results did not include the pro forma effect of expensing stock
options of approximately 4 cents per diluted share. The following
table compares 2006 guidance with 2005 comparable results after
adjusting for the pro forma effect of stock option expense in fiscal
2005 and a charge related to canceling the test of JBX Grill in the
fourth quarter of fiscal 2005:

    Estimated fourth-quarter fiscal 2006 earnings guidance represents
a 7-10 percent improvement over comparable prior-year results after
adjusting for the noncomparable items noted in the table above. The
primary assumptions on which fourth-quarter earnings guidance is based
are as follows, in approximate amounts:

    --  A 3.5-4.5 percent increase in same-store sales at Jack in the
        Box company restaurants.

    --  Restaurant operating margin at 17.8-18.0 percent of sales
        versus 17.3 percent in 2005, due primarily to lower food
        costs, fixed-cost leverage on increased sales, and profit
        improvement program initiatives.

    --  Gains on the sale of company-operated restaurants and other
        revenues of $8.0-9.0 million, primarily related to the sale of
        10 Jack in the Box restaurants to franchisees, compared with
        $7.5 million in 2005, primarily related to the sale of 12
        company restaurants to franchisees. The fourth-quarter
        forecast excludes the pending Hawaii transaction.

    --  An effective tax rate of 36-36.5 percent compared with 32.2
        percent in 2005.

    --  Capital expenditures of $60 million compared with $47 million
        in 2005, with the increase due in part to investments
        associated with the planned re-imaging of Jack in the Box
        restaurants in 2006.

    Fourth quarter initiatives

    --  In July, Jack in the Box enhanced its dessert menu by adding a
        Chocolate Chip Cookie Cheesecake made with Nestle Toll
        House(R) semisweet chocolate morsels and by re-imaging its
        line of real ice cream shakes. Jack's shakes now feature
        creamy whipped topping and a cherry and are served in a clear
        plastic cup with a dome-shaped lid.

    --  Also in July, Jack in the Box launched a value-friendly combo
        meal called The Big Deal, featuring a chicken sandwich, two
        beef tacos and a 20-ounce beverage for just $2.59.

    --  Additionally, Jack in the Box enhanced its beverage offerings
        by introducing a new brand of orange juice, from Minute
        Maid(R).

    --  Next week, Jack in the Box will add buttermilk biscuits to its
        breakfast menu and introduce two new products: Bacon, Egg &
        Cheese Biscuit and Sausage, Egg & Cheese Biscuit.

    --  Also next week, Jack in the Box will introduce an Outlaw(TM)
        Burger and Outlaw(TM) Spicy Chicken Sandwich, featuring either
        a jumbo beef patty or spicy crispy chicken fillet with two
        fried onion rings, slices of bacon, two slices of American
        cheese, lettuce and tomatoes all topped with KC Masterpiece(R)
        Original Barbecue Sauce and served on a toasted sesame bun.

and accounting rules and interpretations; and adverse economic and
other local, national and international conditions or events that
affect consumer confidence and spending. Costs may exceed projections,

publicity regarding the company, the foodservice industry in general
or particular foods. Further information about factors that could
affect the company's financial and other results is included in the

    Use of non-GAAP financial information

    In this press release, the company provides (i) earnings per
diluted share (EPS) determined in accordance with generally accepted
accounting principles (GAAP) and (ii) EPS adjusted for certain items
as follows:

    --  For the third quarter of fiscal 2005, comparable diluted EPS
        as shown in a table earlier in this press release includes the
        pro forma effect of expensing stock options in accordance with
        SFAS 123.

    --  For fiscal year 2005, comparable diluted EPS as shown in a
        table earlier in this press release includes the pro forma
        effect of expensing stock options in accordance with SFAS 123
        and excludes a charge related to canceling the test of JBX
        Grill in the fourth quarter of fiscal 2005.

    --  For the fourth quarter of fiscal 2005, comparable diluted EPS
        as shown in a table earlier in this press release includes the
        pro forma effect of expensing stock options in accordance with
        SFAS 123 and excludes a charge related to canceling the test
        of JBX Grill in the fourth quarter of fiscal 2005.

    These non-GAAP financial measures are used by the company's
management to evaluate financial operating performance. Use of these
non-GAAP measures also facilitates comparisons between current and
prior period financial results, estimates of future results, and to
the results of the company's competitors. These financial measures are
also comparable to forecasts made by securities analysts and others,
which generally exclude special items as they are difficult to predict
in advance. Non-GAAP measures are not intended to be a substitute for
net earnings determined in accordance with GAAP.
