International Speedway Corporation (ISC) doesn't believe in slow and steady. The company is the top motorsports operator in the US with more than a dozen racetracks hosting more than 100 events annually. Its race facilities include Daytona International Speedway (home of the Daytona 500), Talladega Superspeedway, and Michigan International Speedway. In addition, ISC operates the Daytona 500 EXperience theme park and museum and it owns 50% of motorsports merchandiser Motorsports Authentics with rival Speedway Motorsports. Former CEO James France and his family own about 70% control of the company. Events sanctioned by NASCAR, also controlled by the France family, account for about 90% of sales.
