IMAX CORPORATION REPORTS SECOND QUARTER 2013 FINANCIAL RESULTS

HIGHLIGHTS

NEW YORK, NY – July 25, 2013 – IMAX Corporation (NYSE:IMAX; TSX:IMX) today reported second quarter 2013 revenues of $82.3 million, adjusted EBITDA as calculated in accordance with the Company’s credit facility of $32.2 million, adjusted net income of $15.0 million, or $0.22 per diluted share, and reported net income of $11.8 million, or $0.17 per diluted share.

“In the second quarter we remained focused on executing our strategy of expanding the network and delivering solid global box office and per screen performance, which resulted in strong recurring revenue growth,” said Richard L. Gelfond, IMAX Chief Executive Officer. “Strategic investments - including our innovative laser projection system - along with some non-recurring items, contributed to higher operating expenses in the quarter.”

“When you take into account the healthy backlog at the end of the second quarter, along with the substantial signing activity over the past few weeks, including last night’s Wanda/AMC announcement, the result is a strong pipeline for continued network expansion over the coming years,” Gelfond continued. “We believe that this, together with our world-class brand and our increasing ability to tailor our programming globally, positions the Company well for long-term growth and an exciting future.”

Network Growth Update

The total IMAX^® theatre network consisted of 767 systems as of June 30, 2013, of which 634 were in commercial multiplexes. There were 284 theatre systems in backlog as of June 30, 2013, compared to 280 theatre systems in backlog as of June 30, 2012. With the inclusion of the recently announced 35 theatre agreement with CJ CGV as well as the 45 to 130 theatre agreement with Wanda/AMC, the Company’s total year-to-date signings are between 140 and 225, depending on whether Wanda/AMC exercises their option for 80 additional theatres under their most recent agreement. For a breakdown of theatre system signings, installations, network and backlog by type, please see the end of this press release.

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 share-based compensation and the related tax impact. 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 Fixed Charge Coverage Ratio (as defined in the Credit Agreement) of not less than 1.1:1.0. The Company will also be required to maintain minimum EBITDA (as defined in the Credit Agreement) of $70.0 million between closing and September 30, 2013, which requirement increases to $80.0 million on December 31, 2013, $90.0 million on December 31, 2014, and $100.0 million on December 31, 2015. The Company must also maintain a Maximum Total Leverage Ratio (as defined in the Credit Agreement) of 2.5:1.0 between closing and September 30, 2013, which requirement decreases to (i) 2.25:1.0 on December 31, 2013; (ii) 2.00:1:0 on December 31, 2014; and (iii) 1.75:1.0 on December 31, 2015. The ratio of total debt to EBITDA was 0.17:1 as at June 30, 2013, where Total Debt (as defined in the Credit Agreement) is the sum of all obligations evidenced by notes, bonds, debentures or similar instruments and was $18.0 million. EBITDA is calculated as follows:
