Item 2.02. Results of Operation and Financial Condition.

Preliminary Financial Information

In conjunction with the cash tender offer (the “Offer”) by an affiliate of Apollo Management VIII, L.P. (“Apollo”) to purchase all of the issued and outstanding shares of common stock, and any associated rights, of CEC Entertainment, Inc. (the “Company” or “CEC”) and the subsequent merger pursuant to which the Company will become a wholly-owned subsidiary of Apollo (the “Merger”), the Company filed a Schedule 14D-9 with the Securities and Exchange Commission on January 22, 2014, which contained its preliminary unaudited comparable store sales of 0.4%, total revenue of approximately $822 million, net income of approximately $48 million, and adjusted EBITDA of approximately $169 million for its fiscal year ended December 29, 2013. For the fourth quarter of 2013, the Company’s preliminary comparable store sales were down 1.3%. Preliminary comparable store sales for the 4th quarter of 2013 by Period were: up 0.3% for Period 10, up 3.0% for Period 11 and down 6.3% for Period 12. Severe winter weather storms had a significant negative impact on comparable store sales for Period 12. In addition, preliminary net income for the fourth quarter of 2013 is expected to be negatively impacted by a non-cash asset impairment charge of approximately $2.3 million. The Company’s preliminary estimates for fourth quarter earnings per share is a loss of approximately $0.01 per share.

The preliminary financial results presented above are subject to the completion of the Company’s financial closing procedures for the fourth quarter and full fiscal year ended December 29, 2013. Those procedures have not been completed. Accordingly, these preliminary results could change and those changes could be material.

Non-GAAP Financial Measures: The Company reports and discusses its operating results using financial measures consistent with accounting principles generally accepted in the United States (“GAAP”). From time to time in the course of financial presentations, earnings conference calls or otherwise, the Company may disclose certain non-GAAP financial measures. The Company generally has not previously disclosed adjusted EBITDA in its financial results but is disclosing it on a preliminary basis for the fiscal year ended December 29, 2013 because it was a metric provided by the Company to Apollo in connection with the Merger negotiations and in the Offer, and thus the Company believes disclosure of this information on a preliminary basis could be useful to Company shareholders in evaluating the Offer. The non-GAAP financial measures should not be viewed as alternatives or substitutes for the Company’s reported GAAP results. A reconciliation to the most directly comparable GAAP financial measure to Adjusted EBITDA is below (in millions):

Forward-Looking Statements

Statements herein regarding the proposed transaction among Apollo and CEC, future financial and operating results, benefits and synergies of the transaction, future opportunities for the combined company and any other statements about future expectations and the intent of any parties about future actions constitute “forward-looking statements” as defined in the federal securities laws. Forward-looking statements may be identified by words such as “believe,” “expects,” “anticipates,” “projects,” “intends,” “should,” “estimates” or similar expressions. Such statements are based upon current beliefs, expectations and assumptions and are subject to significant risks and uncertainties. There are a number of important factors that could cause actual results or events to differ materially from those indicated by such forward-looking statements, including, among other things, risks relating to the expected timing, consummation, and financial benefits of the Offer and the Merger. Other risk factors include, but are not limited to:

CEC believes these forward-looking statements are reasonable; however, undue reliance should not be placed on any forward-looking statements, which are based on current expectations. All written and oral forward-looking statements attributable to Apollo or CEC or persons acting on Apollo’s or CEC’s behalf are qualified in their entirety by these cautionary statements. Further, forward-looking statements speak only as of the date they are made, and Apollo and CEC undertake no obligation to update or revise forward-looking statements to reflect changed assumptions, the occurrence of unanticipated events or changes to future operating results over time unless required by law. Past financial or operating performance is not necessarily a reliable indicator of future performance and you should not use our historical performance to anticipate results or future period trends.

Additional factors that may affect future results are contained in the Company’s filings with the SEC, including its Annual Report on Form 10-K for the year ended December 30, 2012 and subsequent filings, which are available at the SEC’s website at http://www.sec.gov. The information set forth herein speaks only as of the date hereof, and any intention or obligation to update any forward-looking statements as a result of developments occurring after the date hereof is hereby disclaimed unless required by law.
