* The remainder of this cover page shall be filled out for a reporting person’s initial filing on this form with respect to the subject class of securities, and for any subsequent amendment containing information which would alter disclosures provided in a prior cover page.

The information required on the remainder of this cover page shall not be deemed to be “filed” for the purpose of Section 18 of the Securities Exchange Act of 1934 (“Act”) or otherwise subject to the liabilities of that section of the Act but shall be subject to all other provisions of the Act (however, see the Notes).

EXPLANATORY NOTE

This Amendment No. 7 (“Amendment No. 7”) 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. 7 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 Common Unit Adjustment Agreement or the Schedule 13D, as applicable.

Item 3 is hereby amended to add the following:

On March 15, 2018, pursuant to the Common Unit Adjustment Agreement, the Issuer notified the Reporting Person that on or about March 29, 2018, the Reporting Person shall receive, through its wholly-owned subsidiary, Cinemark USA, Inc. and its wholly-owned subsidiary Cinemark Media, Inc., 908,042 newly issued NCM Units in accordance with the 2017 Annual Adjustment.

In accordance with the Common Unit Adjustment Agreement, no payments were made by or on behalf of any party in exchange for the NCM Units received pursuant to the 2017 Annual Adjustment.

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. 7, in accordance with the 2017 Annual Adjustment, for investment purposes pursuant to the terms of the Common Unit Adjustment Agreement.

Item 5. Interest in Securities of the Issuer

Item 5 is hereby amended as follows:

(a) Including the NCM Units referred to in this Amendment No. 7, 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 28,779,904 shares of Common Stock. Cinemark’s beneficial ownership of 28,779,904 shares of Common Stock equals approximately 27.0% of the Issuer’s issued and outstanding shares of Common Stock on an as-converted basis as of the filing date.

Neither the filing of this Amendment No. 7 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. 7 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.
