Gelfond, IMAX CEO, commented on the growth areas, "We made significant inroads in several of the BRIC nations, particularly in China, where we signed our first full joint revenue sharing arrangement for 75 theaters with Wanda Cinema Line, the largest international theater deal in our history. Domestically, we continued to penetrate small to mid-tier domestic markets with new theater agreements with prominent regional exhibitors like Premiere Cinema Corp. and Warren Theatres." On average, analysts expect the stock to gain 25% over the next year. The stock is trading at 21 times its estimated 2012 earnings with 63% buy ratings.
