              Jack in the Box Inc. Reports Second-Quarter Results;
        Provides Third-Quarter Guidance and Updates Fiscal 2005 Forecast

     SAN DIEGO--(BUSINESS WIRE)--May 18, 2005--Jack in the Box Inc. (NYSE:JBX)
today reported net earnings of $20.7 million, or 55 cents per diluted share, in
the second quarter ended April 17, 2005, compared with $18.7 million, or 51
cents per diluted share, in the same quarter a year ago. Year to date, net
earnings totaled $46.1 million, or $1.23 per diluted share, compared with $33.0
million, or 90 cents per diluted share, for the first half 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. All numbers presented in this news release reflect adjustments
described in the company's restatement news release, dated Dec. 16, 2004.
     The company also today updated its earnings guidance for fiscal 2005 to
approximately $2.46 per diluted share, compared with $2.43 per share previously
forecast and $2.02 per 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 two new chicken ciabatta sandwiches were a hit with guests and
contributed to a 3.1 percent increase in same-store sales for the quarter on top
of an 8.2 percent increase last year," said Robert Nugent, chairman and chief
executive officer. "With a new instant-win game currently under way at Jack in
the Box and two new ciabatta burgers slated for introduction at the end of May,
we believe we will maintain our positive sales momentum in the second half of
the fiscal year."

     Second Quarter Initiatives

     --   New products at Jack in the Box(R) restaurants included two premium
          sandwiches served on lightly toasted artisan ciabatta bread:
          Bruschetta Chicken and Classic Chicken.

     --   As planned, the company began testing a new interior and exterior
          design for its Jack in the Box restaurants. The design enhancements
          are intended to create a more contemporary atmosphere and promote more
          in-restaurant dining. Approximately 50 restaurants will test the new
          designs in fiscal 2005, and assuming results are successful, the
          company expects to re-image approximately 200 restaurants each year
          thereafter.

     "Developing innovative new products and enhancing our restaurant facilities
are part of our holistic strategy to reinvent the Jack in the Box brand," Nugent
said. "Using the consumer research facilities at our new Innovation Center,
along with extensive field research and market analysis, we continue to identify
opportunities to improve our menu and facilities, as well as guest service. This
research is benefiting both our Jack in the Box and JBX Grill(TM) brands, and
will be essential in determining the next test phase of our new fast-casual JBX
Grill concept."

     --   The company continued testing JBX Grill at nine locations in Boise,
          Idaho, and Bakersfield, Calif., where the concept was enhanced based
          on learnings gained at two prototype restaurants in San Diego. For
          example, the dining areas are now larger and more open, the service
          lobbies were redesigned to improve traffic flow and merchandising, and
          the menu was expanded with flame-grilled products. With these market
          tests successfully launched and the purpose of the San Diego "learning
          labs" fulfilled, the company converted the menus at the two prototype
          restaurants back to Jack in the Box.

     --   In February, the board of directors authorized a $65 million program
          to repurchase shares of the company's common stock using existing cash
          resources. During the quarter, the company repurchased approximately
          965,000 of its shares. This buyback program was completed after
          quarter end, on May 6, with a total of approximately 1.7 million
          shares repurchased.

     --   To reduce exposure to rising interest rates, the company converted
          approximately $130 million of its $275 million term loan at floating
          rates to a fixed interest rate for the next three years.

     Second Quarter Financial Highlights

     --   Earnings per diluted share were 5 cents higher than the company's
          guidance, resulting from higher same-store sales, improved labor
          management, fixed-cost sales leverage and Profit Improvement Program
          initiatives, partially offset by higher beef, produce and cheese costs
          (+9 cents); higher other revenues, primarily from the sale of Jack in
          the Box restaurants to franchisees (+2 cents); lower interest expense
          (+1 cent); higher SG&A expense, due primarily to increases in
          incentive accruals, as well as expenses associated with Sarbanes-Oxley
          compliance (-5 cents); and a non-recurring expense associated with an
          arbitration award in connection with the cancellation of a utility
          contract (-2 cents).

     --   12 new company and franchised Jack in the Box and JBX Grill
          restaurants opened, as forecast, versus 14 in FY04, bringing to 2,024
          the total number of Jack in the Box and JBX Grill restaurants at
          quarter end, comprising 1,545 company and 479 franchised locations; 18
          new company and franchised Qdoba Mexican Grill(R) sites opened versus
          15 forecast and 7 in FY04, bringing to 215 the total number of Qdoba
          restaurants at quarter end, comprising 51 company and 164 franchised
          locations; and 3 new Quick Stuff(R) convenience stores opened,
          bringing to 35 the total number of c-store locations at quarter end
          versus 21 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 3.1 percent
          on top of an 8.2 percent increase in 2004. The increase was higher
          than the 1.0 percent increase forecast, due in part to strong sales of
          premium products, including the new chicken ciabatta sandwiches. Year
          to date, same-store sales increased 2.6 percent on top of a 5.2
          percent increase for the same period last year. During the quarter,
          same-store sales at Qdoba increased in the double-digit range on top
          of a double-digit increase in FY04. Qdoba extended to 23 its string of
          consecutive quarters with same-store sales higher than the prior year.

     --   Distribution and convenience-store sales were $74 million versus $39
          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 $8.6 million compared with $5 million in FY04,
          primarily related to the sale of 13 Jack in the Box restaurants to
          franchisees versus 7 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, which
          it may use to reinvest in its restaurant re-image program and
          repurchase shares without incurring additional debt or diluting
          equity.

     --   Total revenues were $577 million versus $517 million in FY04. Year to
          date, total revenues were $1.3 billion versus $1.2 billion last year.

     --   Restaurant operating margin was 17.1 percent of sales compared with
          16.7 percent forecast and 17.5 percent in FY04. The increase versus
          forecast was primarily due to the increase in same-store sales,
          fixed-cost leverage, improved labor management and Profit Improvement
          Program initiatives, partially offset by higher commodity costs and
          utility expenses. Compared with the prior year, beef costs were up
          approximately 18 percent for the quarter.

     --   Costs of revenues were at 82.7 percent compared with 83.4 percent
          forecast and 82.2 percent in FY04, with the increase versus last year
          due primarily to significant increases in distribution and c-store
          sales at lower margins.

     --   SG&A expense rate was 11.1 percent of revenues compared with 10.7
          percent forecast and 11.3 percent in FY04. The increase versus
          forecast was due primarily to higher incentive accruals based on the
          company's improved performance, and costs associated with
          Sarbanes-Oxley compliance.

     --   Interest expense was $3.5 million versus $4 million forecast,
          approximately the same as in FY04, due primarily to
          lower-than-anticipated borrowing rates and to the refinancing and
          subsequent repricings of the company's credit facility.

     --   Income tax rate was 35.9 percent versus 36.0 percent in FY04.

     --   Weighted average diluted shares outstanding were 37.4 million versus
          36.8 million in FY04, with the increase due primarily to additional
          stock option exercises, partially offset by the company's share
          repurchase program. The increase in FY05 unfavorably impacted the EPS
          comparison with FY04 by 1 cent.

     --   Capital expenditures were approximately $20 million, as forecast,
          versus $38 million in FY04, which included the cost of the company's
          70,000-square-foot Innovation Center that opened in March 2004.

     --   Earnings from operations were $35.8 million and
          depreciation/amortization was $19.8 million versus $33.3 million and
          $19.6 million, respectively, in FY04.

     --   Current ratio was 0.9 versus 0.8 in FY04. Cash balances were $120.7
          million versus $11.1 million a year ago, due primarily to strong
          operating cash flows, payments from franchisees on notes receivable,
          and proceeds from sales of restaurants to franchisees as part of the
          company's strategic plan to expand its franchising program.

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

     --   Accounts and notes receivable decreased $7 million from a year ago,
          due primarily to repayment of short-term loans made to qualified Jack
          in the Box franchisees for purchases of restaurants from the company.

     --   Other current assets were $68 million compared with $148 million in
          FY04. Last year's balance included the company's purchase of 80 Jack
          in the Box restaurant properties in 2004 that it subsequently resold
          and leased back at more favorable lease rates.

     --   Other assets increased $24 million from a year ago, due primarily to
          contributions of $30 million made to the company's qualified pension
          plans in fiscal 2004.

     --   Total debt was $301 million compared with $313 million in FY04. The
          company currently has no balance outstanding on its $200 million
          revolving credit facility.

     --   Stockholders' equity increased $73 million from a year ago, due
          primarily to increased earnings over the past year, as well as to the
          contributions made to the company's qualified pension plans, which
          reduced a negative charge to equity. These increases to equity were
          partially offset by increases in repurchases of the company's common
          stock.

     Third Quarter Initiatives

     --   In April, Jack in the Box restaurants launched "Win Jack's Stuff," an
          instant-win game offering guests who purchase a medium or large combo
          meal a one-in-two chance of winning prizes ranging from food products
          to Kawasaki motorcycles and Nintendo game systems.

     --   Jack in the Box restaurants in April added a new flavor to its line of
          real ice cream shakes, Blueberries 'n' Cream. Earlier this month, Jack
          in the Box added a unique offering to its breakfast lineup: the Meaty
          Breakfast Burrito, a warm flour tortilla stuffed with ham, sausage,
          bacon, scrambled eggs, shredded cheddar and pepperjack cheeses and
          served with a side of fire-roasted salsa. At the end of May, the chain
          will introduce two new premium burgers served on artisan ciabatta
          bread.

     Third Quarter Guidance Highlights (in approximate amounts)

     --   The company today provided its initial guidance for the third quarter
          ending July 10, stating that it expects to earn approximately 60 cents
          per diluted share compared with 56 cents reported last year.

     --   10-12 new company and franchised Jack in the Box restaurants are
          planned to open, including 4 new Quick Stuff convenience stores, as
          well as 12-15 new company and franchised Qdoba restaurants.

     --   Same-store sales at Jack in the Box restaurants are estimated to
          increase approximately 3.0-3.5 percent on top of a 3.9 percent
          increase in the third quarter last year.

     --   Distribution and c-store sales are estimated at $80 million versus $50
          million last year, due primarily to increased distribution sales to
          Qdoba and Jack in the Box franchised restaurants, additional Quick
          Stuff units and higher fuel sales.

     --   Other revenues are estimated at $6-7 million, the same as last year,
          due primarily to the sale of 18-20 restaurants to franchisees versus
          12 last year, with the decrease in average gains this year related to
          the specific sales and cash flows of the restaurants being sold.

     --   Total revenues are estimated at $585 million versus $541 million last
          year.

     --   Restaurant operating margin is estimated at 18.2 percent versus 17.7
          percent last year, due primarily to higher sales, continued
          improvement in labor management and fixed cost leverage, and Profit
          Improvement Program initiatives, partially offset by higher commodity
          costs for beef and produce.

     --   Costs of revenues are expected to be 82.2 percent versus 81.9 percent
          last year, due primarily to significant increases in distribution and
          c-store sales at lower margins, partially offset by higher restaurant
          operating margin.

     --   SG&A expense rate is expected to be 11.1 percent versus 11.3 percent
          last year, due primarily to additional leverage from higher
          distribution and c-store sales, and continued Profit Improvement
          Program initiatives.

     --   Interest expense is expected to be $4.5 million versus $3.8 million
          last year, due primarily to expected increases in borrowing rates,
          including the second-quarter conversion of approximately $130 million
          of floating-rate term loan debt to fixed rates for the next three
          years.

     --   Income tax rate is projected at 37 percent versus 36.9 percent last
          year.

     --   Weighted average diluted shares outstanding are projected to be 36.5
          million versus 37.3 million last year, due primarily to the impact of
          the company's $65 million share repurchase program, which was
          completed on May 6, 2005, partially offset by stock option exercises.

     --   Capital expenditures are estimated at $30-$35 million versus $25
          million last year.

     --   Earnings from operations are estimated at $40 million and
          depreciation/amortization at $20 million versus $37 million and $20
          million, respectively, last year.

     Fiscal 2005 Guidance Update (in approximate amounts)

     --   Current EPS guidance of approximately $2.46 for fiscal 2005 is 3 cents
          higher than prior forecast. The company now estimates that the
          increase in commodity costs, primarily beef, will be about 30 basis
          points higher than last year. The improvement in guidance is due
          primarily to higher same-store sales, fixed-cost leverage, improved
          labor management and Profit Improvement Program initiatives, partially
          offset by higher commodity costs (+9 cents); deferral of stock-option
          expensing until fiscal 2006 as now allowed by SFAS 123R (+3 cents);
          higher gains on sales of restaurants to franchisees (+2 cents); higher
          SG&A, due primarily to increased incentive accruals and costs
          associated with Sarbanes-Oxley compliance (-8 cents); higher shares
          outstanding, due primarily to stock option exercises (-1 cent); and a
          non-recurring expense associated with an arbitration award in
          connection with the cancellation of a utility contract (-2 cents).

     --   45-50 company and franchised Jack in the Box restaurants are expected
          to open, including 14 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 now expected to increase 3.0
          percent for the year.

     --   Other revenues are estimated at $31 million versus $30 million
          previously forecast, due primarily to the sale of 57 Jack in the Box
          restaurants to franchisees - 3 more than prior guidance.

     --   Restaurant operating margin is estimated at 17.3 percent versus 17.2
          percent previously forecast, and 17.0 percent last year. Beef costs
          are expected to increase by 10-12 percent versus a year ago.

     --   SG&A expense rate is expected to be 10.9 percent of revenues versus
          11.4 percent in 2004 and 10.8 percent previously forecast, due
          primarily to higher incentive accruals and expenses associated with
          Sarbanes-Oxley compliance, partially offset by the deferral of
          stock-option expensing until fiscal 2006.

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

     --   Income tax rate is projected at 36.4 percent, the same as previously
          forecast.

     --   Weighted average diluted shares outstanding are projected to be 37
          million.

     --   Capital expenditures are estimated at $125-$135 million, the same as
          previously forecast.
