Stephen E. Siwek testified on behalf of JamSports concerning its lost profits from Clear Channel’s interference with its contract to promote the AMA Supercross motorcycle racing series. Given that JamSports had no history of promoting the series, Siwek, assisted by EI Sr. Economist Gale Mosteller, estimated lost profits using five years of Clear Channel’s Supercross profit summaries as well as revenue-sharing and other terms in JamSports’ promotion agreement. The jury awarded JamSports $90 million in lost profits and punitive damages. JamSports was represented by Segal McCambridge Singer & Mahoney.
