INTERNATIONAL SPEEDWAY CORPORATION REPORTS FINANCIAL

RESULTS FOR THE SECOND QUARTER OF FISCAL 2012

~Company Reiterates Full-Year Financial Guidance~

DAYTONA BEACH, Fla. – July 5, 2012 – International Speedway Corporation (NASDAQ Global Select Market: ISCA; OTC Bulletin Board: ISCB) (“ISC”) today reported financial results for its fiscal second quarter ended May 31, 2012.

“Comparison for the quarter was positively impacted by scheduling changes, primarily due to hosting two additional NASCAR Sprint Cup series events versus the comparable 2011 quarter,” stated ISC Chief Executive Officer Lesa France Kennedy. “While generally pleased with our financial results, attendance-related revenues at our events generated mixed results. Our core fan demographic, which is Middle America, still lacks confidence due to slow job and income growth. Until these trends change, we expect our consumer revenues will remain under pressure.

“Fortunately, we benefit from a solid financial position, which affords us the ability to continue our disciplined capital allocation strategy and maintain our leadership position in the motorsports industry. We see a tremendous opportunity for the Company to grow even stronger as we continue to successfully execute our strategic initiatives.

“We can’t stress enough the importance of supporting the live events by enhancing the experience for our guests. Aside from the positive impact to consumer-related revenues, it supports both corporate sales and influences the long-term health of TV ratings. We are convinced that improving the customer experience through targeted capital improvements will lead to increased ticket sales as well as pricing power over the longer term.”

Second Quarter Comparison

Total revenues for the second quarter ended May 31, 2012 were approximately $179.6 million, compared to revenues of approximately $138.8 million in the prior-year period. Operating income was approximately $33.2 million during the period compared to approximately $24.1 million in the second quarter of fiscal 2011.

Non-GAAP net income and diluted earnings per share below are derived by adjusting amounts determined in accordance with GAAP for certain items presented in the accompanying selected operating statement data, net of taxes.

The adjustments for 2011 relate to carrying costs of our Staten Island property, impairments of certain other long-lived assets and the Hollywood Casino at Kansas Speedway — equity in net loss from equity investment.

The adjustments for 2012 relate to carrying costs of our Staten Island property, legal settlement, impairments of certain other long-lived assets, loss on early redemption of debt and net gain on sale of certain assets.

The Company believes such non-GAAP information is useful and meaningful, and is used by investors to assess its core operations, which consist of the ongoing promotion of racing events at its major motorsports entertainment facilities. Such non-GAAP information adjusts for items that are not considered to be reflective of the Company’s continuing core operations at its motorsports entertainment facilities. The Company believes that such non-GAAP information improves the comparability of its operating results and provides a better understanding of the performance of its core operations for the periods presented. The Company uses this non-GAAP information to analyze the current performance and trends and make decisions regarding future ongoing operations. This non-GAAP financial information may not be comparable to similarly titled measures used by

other entities and should not be considered as an alternative to operating income, net income or diluted earnings per share, which are determined in accordance with GAAP. The presentation of this non-GAAP financial information is not intended to be considered independent of or as a substitute for results prepared in accordance with GAAP. The Company uses both GAAP and non-GAAP information in evaluating and operating its business and as such deemed it important to provide such information to investors.

From a marketing partnership perspective, the Company has agreements in place for approximately 92.0 percent of its gross marketing partnership revenue target. It has secured all NASCAR Nationwide and Camping World Truck series event entitlements with only two NASCAR Sprint Cup event entitlements open for the 2012 season, which the Company expects to secure. Based on current interest from corporate prospects, the Company expects to be within a couple percentage points of its gross corporate partnership target for the year.

External Growth, Financing-Related and Other Initiatives

Hollywood Casino at Kansas Speedway

The Hollywood Casino at Kansas Speedway, which opened on February 3, 2012, features a 95,000 square-foot casino with 2,000 slot machines and 52 table games, a 1,253 space parking structure as well as a sports-themed bar, dining and entertainment options. The Company’s 50/50 joint venture partner Penn National Gaming, Inc. is responsible for the development and operation of the casino.

The Company estimates that its share of capitalized development costs for the project, excluding its contribution of land, will be approximately $145.0 million, which is below the original estimate of approximately $155.0 million. Through May 31, 2012, the Company has funded approximately $134.3 million of these capitalized development costs. In addition, the Company funded certain working capital needs of the project prior to opening. Start up and related costs through opening were expensed through equity in net loss from equity investments. Cash flow from the casino’s operations is first being used to fund the remaining development costs

and will subsequently start being distributed to the joint venture partners in accordance with the partnership agreement. The Company estimates that the Hollywood Casino at Kansas Speedway will provide approximately $3.0 million in equity income in fiscal 2012.

Liquidity

During ISC’s fiscal 2012 second quarter, it completed the redemption of all of its outstanding 5.4 percent Senior Notes. ISC used additional capacity on its line of credit to retire all of the notes, for an aggregate price equal to the $87.0 million outstanding principal amount plus a redemption premium of approximately $9.0 million and accrued interest up to, but excluding, the redemption date.

The Company is monitoring the current interest rate environment to potentially refinance the borrowings of the redeemed notes with lower cost alternatives and extend a significant portion of its near-term debt maturities.

Capital Spending

The Company competes for the consumers’ discretionary dollar with many entertainment options such as concerts and other major sporting events, not just other motorsport events. To better meet its customer’s expectations, ISC is committed to improving the guest experience at its facilities through on-going capital improvements that position it for long-term growth.

For the six months ended May 31, 2012, the Company spent $26.1 million on capital expenditures for projects at its existing facilities. In comparison, capital expenditures for the first six months of fiscal 2011 totaled approximately $25.3 million, which included $23.9 million for projects at its existing facilities. The remaining expenditures were associated with additional capitalized costs for the Staten Island property.

At May 31, 2012, the Company had approximately $47.9 million remaining in capital projects currently approved for its existing facilities. These projects include:

As a result of these currently approved projects and anticipated additional approvals in fiscal 2012, the Company expects its total fiscal 2012 capital expenditures at its existing facilities will be approximately $80.0 million to $90.0 million depending on the timing of certain projects. The Company reviews the capital expenditure program periodically and modifies it as required to meet current business needs.

The Company is currently in the process of reviewing highly impactful projects that would necessitate an increase in its capital spending at existing facilities above recent levels beginning in 2013. However, any substantial increase in spending above recent levels will depend upon several factors such as a stable economic operating environment, credit availability, and, preferably, the sale of the Company’s Staten Island property.

Ms. France Kennedy added, “Last week at Daytona, we filed a Planned Master Development application, which is the first step in the pursuit of potential redevelopment projects at the ‘World Center of Racing.’ While many aspects of the projects are yet to be determined, such projects could include a complete overhaul of the entire frontstretch grandstands, creating a world-class motorsports entertainment facility including features such as new seats, suites and guest amenities, as well as new entry points, improved fan conveyance, a sleek exterior, first-class interior areas, and a redesigned midway for fans.”

Dividend and Share Repurchase

During the second quarter, the Company increased its annual dividend by $0.02 to $0.20 per share, marking the 39th consecutive year that ISC has paid a dividend to its shareholders. The Company did not purchase any shares of its Class A common shares during its second quarter.

In connection with the Company’s Stock Purchase Plan, for the six months ended May 31, 2012, ISC purchased 405,538 shares of its Class A stock for approximately $10.3 million, bringing the total number of shares purchased from December 2006 through May 2012 to approximately 7.1 million shares. At the end of the second quarter, the Company had approximately $61.7 million in remaining capacity on its $330.0 million authorization.

Returning capital, through repurchasing shares and an annual dividend payment continues to be an important component of ISC long-term capital allocation strategy. The Company is currently only buying shares opportunistically based on levels of its stock price. The Company anticipates that it will spend a minimum of $20.0 million in returning capital to its shareholders for the year.

Outlook

ISC reiterates its 2012 total revenue guidance range of $610.0 million to $630.0 million. In addition, the Company is maintaining its fiscal 2012 full year non-GAAP earnings range of $1.50 to $1.60 per diluted share after-tax. The Company is more comfortable at the low end of the ranges.

ISC’s 2012 financial guidance excludes any future loss or gain on impairment or disposal of long-lived assets which could be recorded as part of capital improvements resulting in removal of assets not fully depreciated; gain or loss on the sale of its Staten Island property; unanticipated further impairment of the property and the ongoing carrying costs; legal settlement; and the loss on early redemption of debt.

In closing, Ms. France Kennedy stated, “Our top priority at ISC is to provide superior, innovative and thrilling guest experiences. To remain true to this vision and compete for the consumers’ discretionary dollar with other entertainment options, we must invest in capital enhancements that provide fan-friendly amenities consistent with consumer expectations. We are confident that by delivering memorable guest experiences along with attractive pricing and fantastic racing, ISC will generate stronger revenues and bottom-line results.”
