IMAX CORPORATION REPORTS SECOND QUARTER 2018 RESULTS

HIGHLIGHTS

NEW YORK – July 25, 2018 – IMAX Corporation (NYSE:IMAX) today reported second quarter 2018 revenues of $98.3 million, gross profit of $60.4 million and net income attributable to common shareholders of $7.6 million, which calculates to $0.12 per diluted share. Adjusted net income attributable to common shareholders for the second quarter was $19.0 million, which calculates to $0.30 per diluted share. Adjusted EBITDA per Credit Facility was $39.5 million. For reconciliations of reported results to non-GAAP financial results, and for the definition and reconciliation of Adjusted EBITDA per Credit Facility, please see the end of this press release.

“Building on our first quarter momentum, we continued to demonstrate the value of our differentiated consumer experience, expanding global footprint and focus on blockbuster content from around the world. These factors, coupled with our continued focus on controlling costs, helped drive second quarter adjusted EBITDA of $39.5 million, a 35% increase compared to the second quarter last year. Through the first six months of 2018, adjusted EBITDA is up 49% compared to the same period last year,” said IMAX CEO Richard L. Gelfond. “Not only are studios emphasizing blockbuster-type content, consumers are increasingly seeking differentiated ways to experience that content. We believe IMAX is uniquely positioned to benefit from these trends, especially with the roll out of our new IMAX^® with Laser experience, which we expect will further increase the differentiation of The IMAX Experience^®.”

Second Quarter 2018 Results

Network Update

During the quarter, the Company installed 31 theater systems, 30 of which were for new theater locations. The total IMAX^® theater network consisted of 1,410 systems as of June 30, 2018, of which 1,314 were in commercial multiplexes. There were 635 theaters in backlog as of June 30, 2018, compared to the 580 in backlog as of June 30, 2017.

IMAX also signed contracts for 40 new theaters and 98 upgrades in the second quarter of 2018. For a breakdown of theater system signings, installations, network and backlog by type for the second quarter of 2018, please see the end of this press release.

Box Office Update

Gross box office from IMAX DMR^® films increased 27.4% to $342.6 million in the second quarter of 2018 from $268.9 million in the second quarter of 2017. Gross box office was generated primarily by the exhibition of 14 films (10 new and 4 carryovers), as compared to 16 films (11 new and 5 carryovers) exhibited in the second quarter of 2017.

Second Quarter Consolidated Results

The gross margin across all segments in the second quarter of 2018 was $60.4 million, or 61.4% of total revenues, compared to $49.5 million, or 56.4% of total revenues, in the second quarter of 2017. Operating expenses (which includes SG&A, excluding stock-based compensation, plus R&D) were $30.3 million in the quarter.

Gelfond continued, “Blockbuster content from Hollywood, China, India and South Korea will hit IMAX screens across the globe this year. Expanding our content offering by including more local-language titles is a key initiative of the Company, given our 1,300-plus screens span nearly 80 countries. We believe that tailoring our slate to the varying consumer preferences in diverse markets such as China will increase the box office productivity of our network. In addition to the compelling mix of global blockbusters, we are also confident that the launch of our new global brand campaign will more effectively communicate to consumers the benefits of the premium IMAX experience. We expect the new brand campaign, combined with the launch of IMAX with Laser and our growing global footprint, to drive incremental attendance at IMAX screens around the world.”

Non-GAAP Financial Measures:

In this release, the Company presents adjusted net income, adjusted net income per diluted share, adjusted net income attributable to common shareholders and adjusted net income attributable to common shareholders per diluted share, EBITDA and adjusted EBITDA as supplemental measures of performance of the Company, which are not recognized under U.S. GAAP. The Company presents 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 net income. In addition, the Company presents adjusted net income attributable to common shareholders and adjusted net income attributable to common shareholders per diluted share because it believes that they are important supplemental measures of its comparable financial results and could potentially distort the analysis of trends in business performance and it wants to ensure that its investors fully understand the impact of net income attributable to non-controlling interests and its stock-based compensation (net of any related tax impact) in determining net income attributable to common shareholders. 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 net income, adjusted net income per diluted share, adjusted net income attributable to common shareholders and adjusted net income attributable to common shareholders per diluted share should be considered in addition to, and not as a substitute for, net income and net income attributable to common shareholders and other measures of financial performance reported in accordance with U.S. GAAP.

Management uses “EBITDA”, as such term is defined in the Company’s credit agreement (and which is referred to herein as “Adjusted EBITDA per Credit Facility”, as the credit agreement includes additional adjustments beyond interest, taxes, depreciation and amortization). Adjusted EBITDA per Credit Facility (each as defined below) should not be construed as substitutes for net income or as better measures of liquidity as determined in accordance with U.S. GAAP. The Company believes that Adjusted EBITDA per Credit Facility is relevant and useful information widely used by analysts, investors and other interested parties in the Company’s industry.
