Imax shares reached an all-time high on Monday, with a nearly 6% jump, driven by strong box office receipts from Christopher Nolan's film "The Odyssey." The film has generated $221 million in global box office sales. CEO Rich Gelfond described the company's momentum as a "flywheel" based on fundamentals, and noted the stock is up 37% year-to-date and 100% over the last 12 months, set to close above $50 per share for the first time. Gelfond also reiterated that the company remains open to potential sale talks.
