IMAX CORPORATION REPORTS FOURTH QUARTER AND FULL YEAR 2013 FINANCIAL RESULTS

HIGHLIGHTS

NEW YORK, NY – Feb. 20, 2014 – IMAX Corporation (NYSE:IMAX; TSX:IMX) today reported robust fourth quarter 2013 financial results driven by the combination of strong installations as well as its highest grossing quarterly global box office ever. The Company reported revenues for the fourth quarter 2013 of $105.1 million, adjusted EBITDA as calculated in accordance with the Company’s credit facility of $52.2 million, adjusted net income of $30.8 million, or $0.44 per diluted share, and reported net income of $27.8 million, or $0.40 per diluted share. The Company also reported a fourth quarter per screen average of $366,300.

Full year 2013 revenues were $287.9 million, adjusted EBITDA as calculated in accordance with the Company’s credit facility was $113.2 million, adjusted net income was $55.7 million, or $0.81 per diluted share, and reported net income was $44.1 million, or $0.64 per diluted share. For reconciliations of adjusted net income to reported net income and for the definition of adjusted EBITDA and free cash flow, please see the tables at the end of this press release. The Company also reported a 2013 per screen average of $1.15 million. With the exception of 2010, when the Company’s per screen average was much higher driven by Avatar, the Company’s per screen averages over the past 5 years have been in a range of approximately $1.1 to $1.2 million.

“IMAX fired on all cylinders in the fourth quarter, with an exceptional number of installations and signings, as well as the highest grossing box office in the Company’s history,” said IMAX CEO, Richard L. Gelfond. “Breakout performances by films such as Gravity, Hobbit, and Stalingrad internationally, exemplify the power and differentiation of the IMAX format.” Gelfond continued, “The strong fourth quarter drove over 90% growth in our EBITDA compared to the same period last year, resulting in margin expansion and strong operating leverage for the full year. Overall, 2013 was a very exciting and productive year at IMAX as we effectively streamlined costs, expanded the network, signed a record number of deals and continued to execute on the film front.”

Network Growth Update

In the fourth quarter of 2013, the Company signed contracts for 119 theatre systems and installed 58 theatre systems, of which 4 were upgrades of existing theatre locations, bringing the full year total installations to 112 new theatre systems across 23 countries.

“With our footprint now spanning 57 countries, IMAX is more global than ever before,” added Gelfond. “Moving forward, we are focused on managing all aspects of our business to ensure that we take full advantage of attractive movie-going trends unique to each local market and that we secure IMAX’s position as the world’s premium cinematic experience. Our record level of signings in 2013 will drive ongoing network growth, and we are optimistic about what the future holds.”

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 stock-based compensation (net of any related tax impact) 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 Fixed Charge Coverage Ratio (as defined in the Credit Agreement) of not less than 1.1:1. The Company will also be required to maintain minimum EBITDA (as defined in the Credit Agreement) of $80.0 million on December 31, 2013, which increases to $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 2.25:1 on December 31, 2013, which requirement decreases to 2.0:1 on December 31, 2014, and 1.75:1 on December 31, 2015. The ratio of total debt to EBITDA was nil:1 as at December 31, 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 $nil. EBITDA is calculated as follows:

(1) Includes a tax recovery in discontinued operations of less than $0.1 million and $0.2 million for the three and twelve months ended December 31, 2013, respectively.
