FOR IMMEDIATE RELEASE
INTERNATIONAL SPEEDWAY INITIATES 2006 FINANCIAL GUIDANCE
DAYTONA BEACH, Fla. - December 15, 2005 - International Speedway Corporation (NASDAQ/NM: ISCA; OTC Bulletin Board: ISCB) ("ISC") today initiated financial guidance for the fiscal year ending November 30, 2006.
"ISC will continue to leverage strategic internal initiatives and positive industry trends to fuel its near- and long-term growth," commented Lesa France Kennedy, President of ISC.  "Supported by a portfolio of premier events located in key markets across the country, we remain well positioned to successfully execute our long-term business plan and drive increases in all of our major revenue categories.  At the industry level, NASCAR racing will benefit from increased awareness generated by the promotional commitment from all of the major networks involved in the recently announced broadcast rights agreements.  The sport will maintain a substantial network presence, and will reach a broader fan base through the use of other content platforms.  In addition, the new agreements provide the company with significant long-term revenue and cash flow visibility.  We are committed to prudently investing capital to maintain our track reco rd of building value for our shareholders, and look forward to a strong 2006 and beyond."
Revenues and Earnings per Share:
For the twelve months ending November 30, 2006, the Company anticipates total revenues to range between $780 and $800 million.  In addition, earnings are expected to range between $3.20 and $3.30 per diluted share, excluding potential legal expenses associated with the Kentucky Speedway, LLC civil action filed in July 2005 against NASCAR and ISC.
The United States District Court, Eastern District of Kentucky (the "Court") is expected to render a decision on the Company's motion to dismiss following a hearing which is scheduled on January 12, 2006.  If the Court denies ISC's motion, the Company will proceed with its defense, which could result in additional expenses in the low seven figures, or up to $0.04 per diluted share in earnings, for fiscal 2006.
