IMAX CORPORATION REPORTS FIRST QUARTER 2012 FINANCIAL RESULTS

HIGHLIGHTS

NEW YORK, NY – April 27, 2012 – IMAX Corporation (NYSE:IMAX; TSX:IMX) today reported first quarter 2012 revenues of $55.6 million, adjusted EBITDA as calculated in accordance with the Company’s Credit Facility of $16.4 million, adjusted net income of $4.0 million, or $0.06 per diluted share, and reported net income of $2.6 million, or $0.04 per diluted share. In the first quarter of 2012, the Company incurred a charge of $0.7 million to enable certain theatres to play movies, such as The Dark Knight Rises, in either digital or analog format. 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 first quarter financial results were driven by strong year-over-year increases in recurring revenues, which reflects the powerful combination of film performance and our growing worldwide theatre network, the key ingredients of our business model,” said IMAX Chief Executive Officer, Richard L. Gelfond. “Our rapid global expansion has led to 32% commercial network growth versus the same time last year. In addition, the box office momentum we experienced in the first quarter has continued into the second quarter, with gross box office to date up roughly 500% versus the same period last year and the summer movie season still ahead. We believe that the momentum we are currently experiencing, together with our growing network, backlog of theatres, cutting-edge technology and the introduction of our new brand campaign should result in continued growth over the long-term.”

First Quarter Segment Results

First quarter 2012 total film revenue was $19.1 million, compared to $11.5 million in the first quarter of 2011. Production and IMAX DMR^® revenues were $13.8 million in the first quarter of 2012, versus $7.3 million in the year-ago period. Gross box office from DMR titles was $121.7 million in the first quarter of 2012, compared to $62.3 million in the first quarter of 2011. The average DMR box office per screen in the first quarter of 2012 was $247,600 ($212,400 domestic, $304,100 international).

“Both our domestic and international theatres enjoyed significant per-screen increases in box office during the quarter, which we attribute in part to the ‘halo effect’ of Mission: Impossible – Ghost Protocol and being involved in the right titles for the IMAX brand,” added Mr. Gelfond. “The 2012 IMAX summer movie season kicks off this week, featuring The Avengers, Men in Black 3, Prometheus, The Amazing Spider-Man and Christopher Nolan’s The Dark Knight Rises, which will include at least an hour of footage shot using IMAX cameras. Differentiation continues to be a key focus of our film strategy in 2012 and beyond. In fact, The Avengers: An IMAX 3D Experience, opened in Russia yesterday, a full week in advance of the wide release, and so far we are working with filmmakers on approximately 10 of our 2012 and 2013 films to incorporate various forms of IMAX differentiation.”

In the first quarter of 2012, revenue from joint revenue sharing arrangements was $11.7 million, compared to $4.0 million in the prior-year period. During the quarter, the Company installed 8 new theatres under joint revenue sharing arrangements, compared to 10 in the year-ago period. As of March 31, 2012, there were 265 IMAX^® theatres operating under joint revenue sharing arrangements, compared to 181 joint revenue sharing theatres open as of March 31, 2011.

In the first quarter of 2012, IMAX systems revenue was $15.7 million, compared to $22.3 million in the first quarter of 2011, primarily reflecting the installation of 8 full, new theatre systems and 10 upgrades in the most recent first quarter, compared to 11 full, new systems and 22 upgrades in the first quarter of 2011.

In the first quarter of 2012, the Company signed contracts for 23 theatre systems and installed 26 theatre systems. There were 261 theatre systems in backlog as of March 31, 2012, compared to 263 systems in backlog as of December 31, 2011 and 283 systems in backlog as of March 31, 2011.

2012 Theatre Installation Schedule from March 31, 2012 Backlog

In the first quarter of 2012, the Company installed 16 new IMAX theatre systems. For the second quarter of 2012, 17 to 21 new theatre systems in backlog as of March 31, 2012 are scheduled to be installed. There are 62 to 63 new theatre systems in backlog as of March 31, 2012 that are scheduled to be installed in the second half of 2012. However, in any given year, the Company will sign agreements for new theatres that will install within that same year. Therefore, the Company expects to install more than the 95 to 100 theatres currently scheduled to be installed out of backlog this year. The Company cautions that installations can slip from period to period, usually for reasons beyond its control.

Mr. Gelfond concluded, “2012 is off to a strong start. We are still in the early stages of our international expansion, and our pipeline of new theatre deals remains robust. We believe that the IMAX platform is becoming increasingly important to our business partners and consumers, and we look forward to bringing The IMAX Experience^® to more and more audiences around the world.”

First quarter 2012 total revenues were $55.6 million, adjusted net income was $4.0 million, or $0.06 per diluted share, reported net income was $2.6 million, or $0.04 per diluted share, and adjusted EBITDA as calculated in accordance with the Company’s Credit Facility was $16.4 million. For the first quarter of 2011, the Company recorded revenues of $45.2 million, adjusted net income of $2.5 million, or $0.04 per share, a reported net loss of $1.0 million, or $0.02 per share, and adjusted EBITDA of $9.0 million. Last year’s reported net loss included a one-time charge of $2.1 million, or $0.03 per share, related to an arbitration proceeding arising from a discontinued subsidiary.

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 0.73:1 as at March 31, 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:

Adjusted Net Income and Adjusted Earnings Per Diluted Share Calculations – Quarter Ended March 31, 2012 vs. 2011:

The Company reported net income of $2.6 million or $0.04 per basic and diluted share for the first quarter of 2012, as compared to a net loss of $1.0 million or $0.02 loss per basic share and diluted share for the first quarter of 2011. Net income for the quarter includes a $0.8 million charge or $0.01 per diluted share (2011 – charge of $1.8 million or $0.03 per diluted share) for variable share-based compensation and a deferred tax provision of $0.7 million or $0.01 per diluted share (2011 – benefit of $0.3 million). In 2011, the Company recognized a one-time charge of $2.1 million ($0.03 per diluted share) due to an award arising from an arbitration proceeding brought against the Company in connection with a discontinued subsidiary, which has since been settled. Adjusted net income, which consists of net income excluding the impact of variable share-based compensation, the deferred tax provision and provision for arbitration award was $4.0 million or $0.06 per diluted share in the first quarter of 2012 as compared to adjusted net income of $2.5 million or $0.04 per diluted share for the first quarter of 2011. A reconciliation of net income, the most directly comparable U.S. GAAP measure, to adjusted net income and adjusted net income per diluted share is presented in the table below:
