NEW YORK – July 12, 2023 – IMAX Corporation (NYSE: IMAX) today announced it has filed a proposal to acquire the outstanding 96.3 million shares in IMAX China (HKSE:1970), a Hong Kong-listed subsidiary established by IMAX Corporation to oversee its business in Greater China, for approximately HK$10 per share in cash / $124 million. The offer represents an approximate 49% premium to the the 30-trading day average closing price. Upon approval of the offer and the scheme of arrangement, IMAX Corporation will own 100% of IMAX China.

The proposed acquisition of IMAX China will enable greater operational flexibility to pursue new growth opportunities and applications of IMAX technology in the Chinese market. The transaction is expected to be accretive to IMAX Corporation immediately following completion; for instance, IMAX Corp. first quarter 2023 Adjusted EBITDA would have been $5 million, or 18%, higher including the IMAX China minority interest. The transaction could also unlock approximately $2 million of annual public company cost savings as well as potential tax efficiencies. IMAX Corporation intends to finance the transaction in full through its internal cash resources and/or external debt financing.

“This deal is a win-win for IMAX Corporation and IMAX China, as it unlocks significant financial benefits for IMAX while offering IMAX China investors a meaningful premium to current market prices,” said Rich Gelfond, CEO of IMAX Corporation. “The public listing of IMAX China raised capital to help fuel a period of tremendous growth for IMAX in China, and this transaction has the potential to usher in a new era of expansion for our brand and technology in this thriving market for entertainment.”

The first commercial IMAX location opened in China in 2007 and IMAX China was established as a subsidiary of IMAX Corporation in 2011. IMAX China attracted financial partners in the market to help drive growth and listed on the Hong Kong Stock Exchange in October 2015. Today, there are more than 770 IMAX commercial locations in Greater China — the most of any market in the world.

The first quarter of 2023 saw the highest grossing first quarter ever for global box office from IMAX screens fueled by the highest grossing Chinese New Year ever, leading to our highest grossing quarter ever for local language films. The Company continues to offer a diverse mix of Hollywood and local language blockbusters across its Chinese network. Hollywood films are securing release dates in China with increasing consistency; according to Maoyan, 26 U.S. films have been approved for release in China year to date, versus 25 for the entirety of 2022.

The acquisition of IMAX China is subject to customary closing conditions, including the receipt of IMAX China shareholder and other approvals, and is expected to close later this year. The offer has been approved by both IMAX Corporation and IMAX China’s Boards of Directors.
