Jack in the Box Inc. Reports Third-quarter Results; Updates Fourth Quarter and
Fiscal 2005 Guidance

     SAN DIEGO--(BUSINESS WIRE)--Aug. 10, 2005--Jack in the Box Inc. (NYSE:JBX)
today reported net earnings of $23.9 million, or 66 cents per diluted share, in
the third quarter ended July 10, 2005, compared with $20.7 million, or 56 cents
per diluted share, in the same quarter a year ago. The 2005 results include
approximately 6 cents from the resolution of a prior year's tax position, which
reduced the company's third-quarter tax rate. The company had previously
forecast third-quarter earnings per diluted share of 60 cents. Year to date, net
earnings totaled $70 million, or $1.89 per diluted share, compared with $53.7
million, or $1.46 per diluted share, for the first three quarters of fiscal
2004, which included a first-quarter after-tax charge to interest expense of
$5.7 million, or 15 cents per diluted share, for costs related to refinancing
the company's credit facility.
    The company also today updated its earnings guidance for fiscal
2005 to approximately $2.52 per diluted share, compared with $2.46 per
diluted share previously forecast, and $2.02 per diluted share
reported for fiscal 2004, which was a 53-week fiscal year. Excluding
the 53rd week (+3 cents) and the refinancing charge (-15 cents), last
year's earnings per diluted share were $2.14.
    "Our Jack in the Box(R) restaurants experienced another strong
operating quarter, despite escalating beef costs," said Robert Nugent,
chairman and chief executive officer. "We continue to differentiate
our brand from other QSR chains through the use of high-quality
ingredients such as ciabatta and sourdough bread, and premium products
like our new Ultimate Club sandwich.
    "Along with menu innovation, another important goal of our brand
reinvention strategy is to deliver higher levels of guest service.
We're achieving this through a number of new programs developed
specifically to support our restaurant employees. We have introduced
computer-based training, expanded internal recognition programs, and
provided hourly workers access to affordable healthcare coverage. As a
result of these and other internal service initiatives, we continue to
see reductions in crew turnover, which are at all-time low levels."

    Third Quarter Initiatives

    --  New products at Jack in the Box restaurants included two
        premium burgers served on lightly toasted artisan ciabatta
        bread, the Original Ciabatta Burger and Bacon 'n' Cheese
        Ciabatta Burger. Jack in the Box also enhanced its breakfast
        menu with a protein-packed Meaty Breakfast Burrito, and
        expanded its popular line of real ice cream shakes with a new
        flavor, Blueberries 'n' Cream.

    --  On May 6, as previously disclosed, the company completed its
        $65 million share repurchase authorization, buying back 1.7
        million shares of its stock out of existing cash resources.

    --  The company continued testing new interior and exterior
        designs for its Jack in the Box restaurants. The design
        enhancements are intended to create a more contemporary
        atmosphere and promote more in-restaurant dining.

    --  The company continued testing JBX Grill at nine locations in
        Boise, Idaho, and Bakersfield, Calif.

    Third Quarter Financial Highlights

    --  Earnings per diluted share were 6 cents higher than the
        company's guidance, resulting from: a non-recurring reduction
        in the tax rate for the quarter to 31 percent from 37 percent
        forecast due to the resolution of a prior year's tax position
        (+6 cents); lower SG&A expenses, due in part to Profit
        Improvement Program initiatives and lower training costs
        related to the company's computer-based training system and
        lower restaurant employee turnover (+5 cents); and lower
        restaurant operating margin, partially offset by higher
        franchise royalties and rents (-5 cents). The lower restaurant
        operating margin was due primarily to higher costs for beef
        and produce, partially offset by improved labor management and
        Profit Improvement Program initiatives.

    --  10 new company and franchised Jack in the Box restaurants
        opened, as forecast, versus 14 in FY04, bringing to 2,033 the
        total number of Jack in the Box and JBX Grill restaurants at
        quarter end, comprising 1,534 company and 499 franchised
        locations; 15 new company and franchised Qdoba Mexican
        Grill(R) sites opened, as forecast, versus 12 in FY04,
        bringing to 229 the total number of Qdoba restaurants at
        quarter end, comprising 55 company and 174 franchised
        locations; and 4 new Quick Stuff(R) convenience stores opened,
        also as forecast, bringing to 39 the total number of c-store
        locations at quarter end versus 25 in FY04. Qdoba, Quick Stuff
        and JBX Grill operations are not material components of the
        company's consolidated financial results or projections.

    --  Same-store sales at Jack in the Box restaurants increased 2.8
        percent for the quarter on top of a 3.9 percent increase last
        year. Year to date, same-store sales increased 2.7 percent on
        top of a 4.8 percent increase for the same period last year.
        During the quarter, same-store sales at Qdoba increased in the
        low double-digit range on top of a high single-digit increase
        in FY04. Qdoba extended to 24 its string of consecutive
        quarters with same-store sales higher than the prior year. For
        the quarter, Qdoba was accretive to earnings, as anticipated.

    --  Distribution and convenience-store sales were $81 million
        versus $50 million in FY04. The increase compared with last
        year was due primarily to additional Quick Stuff units and
        higher fuel sales, as well as increased distribution sales to
        Qdoba and Jack in the Box franchised restaurants. Increases in
        fuel sales reflect additional gallons dispensed and higher
        retail prices per gallon, which have proportionately higher
        costs but which yield stable penny profits.

    --  Other revenues were $7.2 million compared with $6.6 million in
        FY04, primarily related to the sale of 20 Jack in the Box
        restaurants to franchisees versus 12 last year, with the
        decrease in average gains this year related to the specific
        sales and cash flows of restaurants sold. The company
        continues to expand its franchising program with the goal of
        improving operating margins and accelerating cash flows.

    --  Total revenues were $590 million versus $541 million in FY04.
        Year to date, total revenues were $1.9 billion versus $1.7
        billion last year.

    --  Restaurant operating margin was 17.2 percent of sales compared
        with 18.2 percent forecast and 17.7 percent in FY04. The
        decrease was primarily due to higher costs for beef and
        produce, partially offset by improved labor management and
        Profit Improvement Program initiatives. Compared with the
        prior year, beef costs were up approximately 18 percent for
        the quarter.

    --  SG&A expense rate was 10.6 percent of revenues compared with
        11.1 percent forecast and 11.3 percent in FY04. The decrease
        versus forecast was due primarily to Profit Improvement
        Program initiatives and lower training costs related to the
        company's computer-based training system and lower restaurant
        employee turnover.

    --  Interest expense was $4.4 million versus $3.8 million in FY04,
        with the increase versus 2004 due primarily to higher interest
        rates, including the second-quarter conversion of
        approximately $130 million of floating-rate term loan debt to
        fixed rates for the next three years. The higher rates were
        partially offset by the company's prior repricings of its
        credit facility.

    --  Income tax rate was 31 percent versus 37 percent forecast and
        36.9 percent in FY04, with the decrease in FY05 due to the
        non-recurring reduction in the current year's quarter
        resulting from the resolution of a prior year's tax position.

    --  Weighted average diluted shares outstanding were 36.4 million
        versus 37.3 million in FY04.

    --  Capital expenditures were approximately $27 million versus
        $30-35 million forecast, reflecting the timing of new store
        openings and the timing of restaurant re-imaging tests.

    --  Earnings from operations were $39 million and
        depreciation/amortization was $20 million versus $37 million
        and $20 million, respectively, in FY04.

    --  Total debt was $300 million compared with $307 million in
        FY04. The company currently has no balance outstanding on its
        $200 million revolving credit facility.

    --  Debt:equity ratio was 0.5:1 versus 0.6:1 last year.

    Fourth Quarter Initiatives

    --  In July, Jack in the Box restaurants added a new flavor to its
        line of real ice cream shakes, Root Beer Float, and last week
        introduced a new premium sandwich, the Ultimate Club, which
        features the chain's signature sourdough bread piled high with
        slices of Black Forest Ham, oven-roasted turkey, bacon,
        cheese, lettuce and tomato. In September, Jack in the Box will
        begin rolling out another new premium item for its breakfast
        menu.

    --  To improve advancement opportunities for its Spanish-speaking
        employees, while also improving guest service and further
        reducing crew turnover, Jack in the Box will roll out an
        innovative ESL (English as a Second Language) program this
        fall. Called "Sed de Saber," meaning "Thirst for Knowledge,"
        this electronic tool covers restaurant-specific communication,
        such as taking orders and reading schedules. The program can
        also enhance the lives of employees in their everyday
        activities and general interaction within their communities.

    Fourth Quarter Guidance Highlights (in approximate amounts)

    The company announced today that it expects to earn approximately
63 cents per diluted share for the fourth quarter ending Oct. 2
compared with 56 cents last year, or 53 cents when excluding the
3-cents benefit of the 53rd week in fiscal 2004. Additional guidance
highlights are as follows:

    --  Same-store sales at Jack in the Box restaurants are estimated
        to increase approximately 3.0 percent on top of a 4.1 percent
        increase in the fourth quarter last year.

    --  Restaurant operating margin is estimated at 17.9 percent of
        sales versus 17.6 percent last year, due in part to same-store
        sales growth and Profit Improvement Program initiatives. This
        guidance also reflects a positive impact from reopening the
        U.S. border to Canadian cattle.

    --  SG&A expense rate is expected to be 10.9 percent of revenues
        versus 11.5 percent last year, due primarily to additional
        leverage from higher distribution and c-store sales, reduced
        training costs, and continued Profit Improvement Program
        initiatives.

    --  Income tax rate is projected at 37 percent versus 35.3 percent
        last year.

    --  Weighted average diluted shares outstanding are projected to
        be 37 million versus 37.6 million last year, due primarily to
        the impact of the company's $65 million share repurchase
        program that was completed on May 6, 2005, partially offset by
        stock option exercises.

    Fiscal 2005 Guidance Update (in approximate amounts)

    The company now expects to earn $2.52 per diluted share for fiscal
2005, which is 6 cents higher than prior forecast, due primarily to
the non-recurring reduction in the tax rate in the third quarter of
FY05. Additional guidance highlights are as follows:

    --  45-50 company and franchised Jack in the Box restaurants are
        expected to open, including 15 new Quick Stuff convenience
        stores; and 75-80 company and franchised Qdoba Mexican Grills
        are expected to open.

    --  Same-store sales at Jack in the Box are expected to increase
        2.5-3.0 percent for the year.

    --  Other revenues are estimated at $32 million versus $31 million
        previously forecast, due primarily to the sale of 58 Jack in
        the Box restaurants to franchisees compared with 57 in prior
        guidance.

    --  Restaurant operating margin is estimated at 17.1 percent of
        sales versus 17.3 percent previously forecast, due primarily
        to higher than expected beef costs that were experienced in
        the third quarter. Although the company expects beef prices to
        ease in the fourth quarter, it now expects a 12-14 percent
        increase in beef costs for the year, up from 10-12 percent
        forecast previously.

    --  SG&A expense rate is expected to be 10.8 percent of revenues
        versus prior guidance of 10.9 percent.

    --  Interest expense is expected to be $18 million, as previously
        forecast.

    --  Income tax rate is projected at 34.8 percent versus prior
        guidance of 36.4 percent, due primarily to the non-recurring
        reduction in the tax rate in the third quarter of FY05.

    --  Weighted average diluted shares outstanding are projected to
        be 37 million, as previously forecast.

    --  Capital expenditures are estimated at $125-130 million.
