IMAX CORPORATION REPORTS SECOND QUARTER 2012 FINANCIAL RESULTS

HIGHLIGHTS

NEW YORK, NY — July 26, 2012 — IMAX Corporation (NYSE:IMAX; TSX:IMX) today reported second quarter 2012 revenues of $70.2 million, adjusted EBITDA as calculated in accordance with the Company’s Credit Facility of $29.0 million, adjusted net income of $14.1 million, or $0.21 per diluted share, and reported net income of $11.1 million, or $0.16 per diluted share. For reconciliations of adjusted net income to reported net income and for the definition of adjusted EBITDA, please see the tables at the end of this press release.

“Our second quarter financial results reflect growth in recurring revenues and gross margin, driven by the power and scale of our global network and the solid performance of a portfolio of films,” said IMAX Chief Executive Officer Richard L. Gelfond. “In addition to our healthy box office results and our expanding network, during the quarter we signed deals for 40 IMAX® theatre systems, our backlog rose sequentially and our pipeline for future theatre deals remains robust. We believe the fundamentals of our business are fueling our earnings growth and positioning us for success over the long term.”

Network Growth Update

In the second quarter of 2012, the Company signed contracts for 40 theatre systems and installed 20 theatre systems. Based on the number of recent theatre signings, the Company has increased its 2012 installations scheduled only from current backlog to approximately 110 new theatres, from its previous outlook of 95 to 100 new theatres from backlog. In addition, the Company may sign agreements for new theatres that install within that same year. The Company cautions that installations can slip from period to period, usually for reasons beyond its control.

There were 280 theatre systems in backlog as of June 30, 2012, compared to 261 systems in backlog as of March 31, 2012 and 294 systems in backlog as of June 30, 2011. For a breakdown of system signings, installations and backlog by type, please see the end of this press release.

Second Quarter Segment Results

Second quarter 2012 total film revenue was $26.5 million, compared to $18.7 million in the second quarter of 2011. Production and IMAX DMR® revenues were $19.7 million in the second quarter of 2012, versus $12.4 million in the year-ago period. Gross box office from DMR titles was $173.5 million in the second quarter of 2012, compared to $107.7 million in the second quarter of 2011. The average DMR box office per screen in the second quarter of 2012 was $341,900, compared to $315,700 in the second quarter of 2011.

“Differentiation continues to be a key focus of our film strategy in 2012 and beyond,” added Mr. Gelfond. “Several recent titles have featured various elements of IMAX differentiation, including Prometheus and The Amazing Spider-Man. The highlight of our third quarter, Christopher Nolan’s The Dark Knight Rises, includes a record of over 70-plus minutes of IMAX footage. We believe that the success of this film will drive longer term benefits to our business like continued theatre signings momentum and interest in IMAX differentiation among filmmakers. In 2013, we will achieve an exciting milestone with the release of two movies featuring sequences filmed with IMAX cameras, Paramount Pictures’ sequel to Star Trek and Lionsgate’s Catching Fire, the second installment of The Hunger Games series.”

In the second quarter of 2012, revenue from joint revenue sharing arrangements was $15.6 million, compared to $8.3 million in the prior-year period.

Mr. Gelfond concluded, “Global demand for The IMAX Experience® is as strong as ever, as evidenced by our box office performance, our upcoming lineup of films and a robust pipeline of theatre deals. We are still in the early stages of our network expansion, having recently increased the estimated number of worldwide IMAX zones by 10% to 1,700 theatres. While we continue to grow at a rapid pace, we are also reinvesting in our brand and technology to even further differentiate the IMAX platform, solidifying our position as the premier global blockbuster entertainment platform.”

Adjusted Net Income and Adjusted Earnings Per Diluted Share Calculation — Beginning Quarter Ended September 30, 2012:

In addition, Adjusted Net Income and Adjusted Earnings Per Diluted Share will be fully tax-affected. The Company believes that this revised definition should provide for a more straightforward and conventional calculation of adjusted earnings.

Non-GAAP Financial Measures:

In this release, the Company presents adjusted EBITDA, adjusted net income and adjusted net income per diluted share as supplemental measures of performance of the Company, which are not recognized under United States generally accepted accounting principles (“GAAP”). The Company presents adjusted EBITDA, adjusted net income and adjusted net income per diluted share because it believes that they are important supplemental measures of its comparable controllable operating performance and it wants to ensure that its investors fully understand the impact of its variable share-based compensation, provision for arbitration award and deferred taxes on its net income. Management uses these measures to review operating performance on a comparable basis from period to period. However, these non-GAAP measures may not be comparable to similarly titled amounts reported by other companies. Adjusted EBITDA, adjusted net income and adjusted net income per diluted share should be considered in addition to, and not as a substitute for, net income and other measures of financial performance reported in accordance with GAAP.

Adjusted EBITDA is calculated on a basis consistent with the Company’s Credit Facility, which refers to Adjusted EBITDA as EBITDA. The Credit Facility provides that the Company will be required to maintain a ratio of funded debt (as defined in the Credit Agreement) to EBITDA (as defined in the Credit Agreement) of not more than 2:1. The Company will also be required to maintain a Fixed Charge Coverage Ratio (as defined in the Credit Agreement) of not less than 1.1:1.0. At all times under the terms of the Credit Facility, the Company is required to maintain minimum Excess Availability of not less than $5.0 million and minimum Cash and Excess Availability of not less than $15.0 million. The ratio of funded debt to EBITDA was 0.63:1 as at June 30, 2012, where Funded Debt (as defined in the Credit Agreement) is the sum of all obligations evidenced by notes, bonds, debentures or similar instruments and was $55.0 million. EBITDA is calculated as follows:
