EXPLANATORY NOTE

This Amendment No. 15 (“Amendment No. 15”) amends the Schedule 13D first filed on March 28, 2011, and as amended subsequently (the “Schedule 13D”), by Cinemark Holdings, Inc. (the “Reporting Person”) with respect to the common stock, par value $0.01 per share of the Issuer (the “Common Stock”). This Amendment No. 15 reflects changes to Items 3, 4 and 5 of the Schedule 13D. Capitalized terms used but not otherwise defined herein shall have their respective meanings under the Schedule 13D.

Item 3 is hereby amended to add the following:

On March 29, 2023, pursuant to the Common Unit Adjustment Agreement, the Reporting Person was notified that it would receive on April 12, 2023 (the “Settlement Date”) through its wholly owned subsidiary Cinemark Media, Inc., 4,849,345 newly issued NCM units in accordance with the 2022 Annual Adjustment.

The information set forth in Item 3 above is incorporated herein by reference.

Item 4 is hereby amended to add the following:

The Reporting Person acquired the NCM Units referred to in Item 3 of this Amendment No. 15 in accordance with the 2022 Annual Adjustment, for investment purposes. Except as set forth above, the reporting person has no present plans or proposals which relate to or would result in any of the events listed in Item 4(a) - (j).

The information set forth in Item 3 above is incorporated herein by reference.

Item 5 is hereby amended as follows:

(a) - (b) Including the Common Stock and the NCM Units to be issued on the Settlement Date referred to in this Amendment No. 15, the Reporting Person, through its wholly-owned subsidiary, Cinemark USA, Inc. and its wholly-owned subsidiary Cinemark Media, Inc., currently may be deemed to beneficially own 48,540,142 shares of Common Stock. Cinemark’s beneficial ownership of 43,690,797 shares of Common Stock and 4,849,345 NCM Units equals approximately 27.40% of the Issuer’s issued and outstanding shares of Common Stock on an as-converted basis as of the filing date based upon 177,178,237 shares of Common Stock issued and outstanding as of November 3, 2022, as reported in the Issuer’s Form 10-Q, as amended, filed on November 9, 2022 (after giving effect to the issuances reported pursuant to the Issuer’s Form 8-K filed on December 2, 2022, the Issuer’s Form 8-K filed on December 30, 2022 and the issuances of the NCM Units to the Reporting Person disclosed herein).

Neither the filing of this Amendment No. 15 nor any of its contents shall be deemed to constitute an admission that any executive officer or director of the Reporting Person or any of its subsidiaries listed on Schedule A hereto, is the beneficial owner of the Common Stock subject of this Amendment No. 15 for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended, or for any other purpose, and such beneficial ownership is expressly disclaimed.

(c) The information set forth in Item 3 above is incorporated herein by reference.
