On March 23, 2016, Carmike Cinemas, Inc. (the “Company”), certain subsidiaries of the Company and Wells Fargo Bank, National Association entered into a Second Supplemental Indenture (the “Supplemental Indenture”) to the indenture dated as of June 17, 2015 (the “Indenture”) with respect to the Company’s 6.00% Senior Secured Notes due 2023 (the “Notes”). The Supplemental Indenture (i) waives the requirement for the Company to comply with the “change of control” covenant in the Indenture in connection with the acquisition of all of the outstanding capital stock of the Company by AMC Entertainment Holdings, Inc. and (ii) amends the reporting covenant in the Indenture to permit any direct or indirect parent company of the Company, if any, that becomes a guarantor of the Notes to satisfy the Company’s obligations under the reporting covenant by filing and furnishing to holders of the Notes the reports, information and other documents required by the Indenture relating to such parent company rather than the Company. The waiver and amendment contained in the Supplemental Indenture required the consent of the holders of at least a majority of the aggregate principal amount of the outstanding Notes, which was obtained through a consent solicitation. The Supplemental Indenture became operative upon the consummation of the consent solicitation on March 24, 2016.

The description of the Supplemental Indenture contained herein is qualified in its entirety by reference to the Supplemental Indenture filed as Exhibit 4.1 to this Current Report on Form 8-K, which is incorporated herein by reference.

Disclosure Regarding Forward-Looking Statements

This Current Report on Form 8-K contains forward-looking statements within the meaning of the federal securities laws. Statements that are not historical facts, including statements about our beliefs, expectations and future performance, are forward-looking statements. Forward-looking statements include statements preceded by, followed by or that include the words, “believes,” “expects,” “anticipates,” “plans,” “estimates,” “seeks” or similar expressions. Forward-looking statements are only predictions and are not guarantees of performance. These statements are based on beliefs and assumptions of management, which in turn are based on currently available information. The forward-looking statements also involve risks and uncertainties, which could cause actual results to differ materially from those contained in any forward-looking statement. Many of these factors are beyond our ability to control or predict. Important factors that could cause actual results to differ materially from those contained in any forward-looking statement include, but are not limited to: the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement with AMC; the inability to complete the proposed merger due to the failure to obtain Carmike stockholder or regulatory approval for the proposed merger or the failure to satisfy other conditions of the proposed merger within the proposed timeframe or at all; disruption in key business activities or any impact on Carmike’s relationships with third parties as a result of the announcement of the proposed merger; the failure to obtain the necessary financing arrangements as set forth in the debt commitment letters delivered pursuant to the merger agreement with AMC, or the failure of the proposed merger to close for any other reason; risks related to disruption of management’s attention from Carmike’s ongoing business operations due to the proposed merger; the outcome of any legal proceedings, regulatory proceedings or enforcement matters that may be instituted against Carmike and others relating to the merger agreement with AMC; the risk that the pendency of the proposed merger disrupts current plans and operations and the potential difficulties in employee retention as a result of the pendency of the proposed merger; the amount of the costs, fees, expenses and charges related to the proposed merger; adverse regulatory decisions; unanticipated changes in the markets for Carmike’s business segments; general economic conditions in Carmike’s regional and national markets; Carmike’s ability to comply with covenants contained in the agreements governing Carmike’s indebtedness; Carmike’s ability to operate at expected levels of cash flow; financial market conditions including, but not limited to, changes in interest rates and the availability and cost of capital; Carmike’s ability to meet its contractual obligations, including all outstanding financing commitments; the availability of suitable motion pictures for exhibition in Carmike’s markets; competition in Carmike’s markets; competition with other forms of entertainment; the effect of Carmike’s leverage on its financial condition; prices and availability of operating supplies; the impact of continued cost control procedures on operating results; the impact of asset impairments; the impact of terrorist acts; changes in tax laws, regulations and rates; and financial, legal, tax, regulatory, legislative or accounting changes or actions that may affect the overall performance of Carmike’s business.

Consider these factors carefully in evaluating the forward-looking statements. Additional factors that may cause results to differ materially from those described in the forward-looking statements are set forth in Carmike’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015, which was filed with the SEC on February 29, 2016, under the heading “Item 1A. Risk Factors,” and in its subsequently filed reports with the SEC, including Forms 10-Q and 8-K. Readers are cautioned not to place undue reliance on the forward-looking statements included in this Current Report on Form 8-K, which speak only as of the date hereof. Carmike does not undertake to update any of these statements in light of new information or future events, except as required by applicable law.
