NEW YORK – Oct. 19, 2016 – IMAX Corporation (NYSE:IMAX) today announced the appointment of Kevin Douglas, Chairman and Founder of Douglas Telecommunications, and Greg Foster, CEO of IMAX Entertainment and Senior Executive Vice President of IMAX Corporation, to its Board of Directors, expanding the board to 11 members from 10. Martin Pompadur, a board member since 2010, has retired.

Douglas Telecommunications is a family investment office through which Douglas manages the Douglas family investment portfolio. Prior to Douglas Telecommunications, he was Chairman of the Board at Rural Cellular Management Corporation. He currently serves on the boards of KSR International Co. and was formerly on the board of Stamps.com.

The Michelle and Kevin Douglas IMAX Theatre and Immersive Media Lab serves as a research and teaching facility for students to learn IMAX filmmaking as well as other immersive entertainment experiences.

Foster joined the Company in 2001, and supports IMAX CEO Richard L. Gelfond in driving the Company’s overall strategy, with a particular emphasis on the Company’s global entertainment activities, including creative, production, film distribution, business affairs, marketing, sponsorship, studio relationships and the revolutionary IMAX DMR^® process. The appointment to the board is pursuant to Foster’s recent contract extension.

“I’m delighted to welcome both Kevin and Greg to our board,” said IMAX CEO Richard L. Gelfond. “Kevin, a respected investor and business adviser, has demonstrated a long-term commitment to IMAX as a shareholder and I have valued his advice over the years. I am pleased that his expertise in identifying new opportunities for growth will be a resource for the board. Greg has played a pivotal role in making IMAX a key player in the global entertainment landscape. His relationship with filmmakers, studios and exhibitors and his passionate commitment to IMAX will be a tremendous asset to our board. I would also like to thank Marty for his many contributions to the Board of Directors and wish him well in his future endeavors.”

Douglas holds a BA from Stanford University and a Doctor of Law degree from the University of California’s Hastings College of Law.
