IMAX CORPORATION REPORTS FOURTH QUARTER AND FULL YEAR 2011 FINANCIAL RESULTS

HIGHLIGHTS

NEW YORK, NY – February 23, 2012 – IMAX Corporation (NYSE:IMAX; TSX:IMX) today reported fourth quarter 2011 revenues of $66.7 million, adjusted net income of $9.2 million, or $0.14 per diluted share, reported net income of $6.3 million, or $0.09 per diluted share, and adjusted EBITDA as calculated in accordance with the Company’s Credit Facility of $21.1 million. 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 fourth quarter financial results came in as expected and the year ended on a positive note with the success of Paramount’s Mission: Impossible – Ghost Protocol, which was released five days early in IMAX,” said IMAX Chief Executive Officer Richard L. Gelfond. “Overall, 2011 was highly productive from a strategic perspective. In addition to the success of Mission: Impossible, we made progress toward introducing best-in-class laser based projection technology, and grew our commercial network by 33%, installing a record 170 IMAX^® theatre systems. This strategic momentum has carried into 2012, as the recent WTO agreement with China, highlighting IMAX, should enhance programming flexibility in our biggest international market, and we have also made early progress toward igniting network growth in Latin America and Europe. While we are disappointed that 2011 did not meet our financial objectives, in 2012, we believe we are positioning ourselves for both financial and strategic success, through our continued focus on differentiation, executing on network growth, and creating a compelling film slate.”

Network Growth Update

2011 marked the second year in a row in which IMAX signed contracts for over 200 theatre systems, and a record year for both new theatre signings and installations. The Company signed contracts for a total of 209 theatre systems in 2011 and installed 170 theatre systems. In the fourth quarter of 2011, the Company signed contracts for 26 theatre systems and installed a record 57 theatre systems. As of December 31, 2011, there were a total of 497 IMAX theatres installed in commercial multiplexes, which represents a 33% increase from the 373 theatres installed as of December 31, 2010. There were 263 theatre systems in backlog as of December 31, 2011, compared to 224 systems in backlog as of December 31, 2010. For a breakdown of system signings, installations and backlog by type, please see the end of this press release.

“The rapid expansion of our network in 2011 was mostly driven by continued success in China, Russia and North America,” said Mr. Gelfond. “In 2012, we are increasingly focused on igniting our growth in underpenetrated markets like South America, Western Europe and India. Our restructured master license agreement in South America is resulting in increased activity in that region of the world and we look forward to the opening of four new IMAX theatres in Brazil in the first half of this year. In addition, we believe the hiring of Andrew Cripps to lead our sales effort in EMEA should be a catalyst for our business in Western Europe, and our recent announcement of new IMAX theatres coming to India should contribute to our ability to release Bollywood titles in IMAX. All of these efforts should accelerate the expansion of our network in these strategically important regions of the world.”

Network Growth Outlook

Based on theatres currently in backlog, the Company expects to install 95 to 100 new theatre systems in 2012 (45 to 50 under revenue sharing arrangements and approximately 50 under sales arrangements). Of the 95 to 100 new theatres expected to be installed in 2012, the Company expects to install approximately 13 to 17 new theatres in the first quarter (7 to 9 under revenue sharing arrangements and 6 to 8 under sales arrangements). Current network growth outlook is based solely on theatres in backlog as of December 31, 2011 and does not include any theatres that may sign and install throughout the year. In 2011, 39% of the 137 new theatres installed were from theatre agreements that were signed in 2011. The Company cautions that installations can slip from period to period, usually for reasons beyond its control.

Fourth Quarter Segment Results

In the fourth quarter of 2011, IMAX systems revenue was $29.8 million, compared to $32.9 million in the fourth quarter of 2010, primarily reflecting the installation of 17 full, new theatre systems in the most recent fourth quarter, compared to 20 full, new systems in the fourth quarter of 2010. The Company also installed one digital upgrade in the fourth quarter of 2011, compared to seven in the same period last year.

Fourth quarter 2011 total film revenue was $18.1 million, compared to $18.0 million in the fourth quarter of 2010. Production and IMAX DMR^® revenues were $12.3 million in the fourth quarter of 2011, versus $13.1 million in the year-ago period. Gross box office from DMR titles was $97.6 million in the fourth quarter of 2011, compared to $101.9 million in the fourth quarter of 2010. The average DMR box office per screen in the fourth quarter of 2011 was $221,600 ($184,900 domestic, $294,700 international).

“The highlight of the fourth quarter was the release of Paramount’s Mission: Impossible – Ghost Protocol,” added Mr. Gelfond. “The film featured scenes shot with IMAX cameras and utilized the early release in IMAX to build positive word of mouth, which helped lead to its status as the must see film of the holiday season. We look forward to an exciting lineup of films for 2012, anchored by key franchise titles including The Avengers, Men in Black 3, The Amazing Spider-Man, The Hobbit: An Unexpected Journey, Skyfall, and the highly-anticipated finale of Christopher Nolan’s Batman trilogy, The Dark Knight Rises, which will feature more footage shot in IMAX than any feature film to date. In addition to our Hollywood tentpole titles, in 2012 we plan to build on the success we have had with local releases in markets like China, and we believe we are now in a position to expand our offering of local content into other international territories, such as France and Russia.”

In the fourth quarter of 2011, revenue from joint revenue sharing arrangements was $8.4 million, compared to $7.8 million in the prior-year period. During the quarter, the Company installed 39 new theatres under joint revenue sharing arrangements, compared to 27 in the year-ago period. As of December 31, 2011, there were 257 IMAX theatres operating under joint revenue sharing arrangements, compared to 171 joint revenue sharing theatres open as of December 31, 2010.

Fourth quarter 2011 gross margin was $29.8 million, compared to $36.4 million in the fourth quarter of 2010, and as a percentage of revenues, gross margin was 44.7% in the quarter, versus 52.6% in the same period last year. Gross margin from DMR was negatively impacted by the purchase of more film prints on certain titles in the fourth quarter, versus last year.

Fourth quarter 2011 revenues were $66.7 million, adjusted net income was $9.2 million, or $0.14 per diluted share, reported net income was $6.3 million, or $0.09 per diluted share, and adjusted EBITDA as calculated in accordance with the Company’s Credit Facility was $21.1 million. Fourth quarter 2010 revenues were $69.2 million, adjusted net income was $14.3 million, or $0.21 per diluted share, reported net income was $54.2 million, or $0.80 per diluted share, which included a one-time, non-cash deferred tax benefit of $54.8 million, or $0.81 per diluted share, and adjusted EBITDA was $25.8 million.

For the full year ended December 31, 2011, total revenues were $236.6 million, adjusted net income was $27.3 million, or $0.40 per diluted share, reported net income was $15.5 million, or $0.23 per diluted share, and adjusted EBITDA as calculated in accordance with the Company’s Credit Facility was $67.7 million. For the full year ended December 31, 2010, total revenues were $248.6 million, adjusted net income was $67.8 million, or $1.02 per diluted share, reported net income was $100.8 million, or $1.51 per diluted share, and adjusted EBITDA was $101.4 million.

Mr. Gelfond concluded, “The strategic momentum of 2011 has continued here in the early weeks of 2012. We enter this new year with a commercial network that is substantially larger than it was a year ago, our mix between domestic and international theatres is moving toward higher-grossing international, and we believe our 2012 film slate reflects what our fans want to experience in IMAX. We believe the fundamentals of our business model – network expansion and higher revenue contribution coming from our higher margin businesses – should position us well for the long-term.”

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 principals (“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 0.82:1 as at December 31, 2011, 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 $55.1 million. Adjusted EBITDA is calculated as follows:
