at Six Flags

Company Repurchases $44 Million of Stock in First Three Months of Year

GRAND PRAIRIE, Texas — April 25, 2012 — Six Flags Entertainment Corporation (NYSE: SIX), the world’s largest regional theme park company, announced today that first quarter 2012 revenue grew 8 percent or $5 million over prior year to $66.4 million, while Adjusted EBITDA(1) for the same three-month period improved by $3.5 million to a $45.6 million loss. For the last twelve months, Adjusted EBITDA reached $354 million while Modified EBITDA(2) margin improved to 37.6 percent—a record high for the company.

“I am pleased to report our eighth consecutive quarter of EBITDA growth,” said Jim Reid-Anderson, Chairman, President and CEO. “As we enter the heart of our operating season, we look forward to introducing even more world-class rides and attractions at each of our parks. We are well-positioned to deliver another excellent year for our guests, employees and shareholders.”

On a constant currency(3) basis, revenue grew 10 percent with approximately 5 percent of the growth due to attendance and pricing improvements, and 5 percent due to the settlement of business interruption insurance proceeds related to Hurricane Irene, totaling $3.0 million.

Total guest spending per capita grew $3.14 or 8 percent with admissions revenue per capita increasing $2.10 or 10 percent to $22.72. In-park per capita revenue increased $1.04 or 6 percent in the quarter and attendance grew 1.5 percent. On a constant currency basis, and excluding the insurance proceeds benefit, total guest spending per capita increased 4 percent or $1.56 primarily driven by an increase in admissions revenue per capita. Deferred revenue as of March 31, 2012, which is made up primarily of season pass sales, increased $10 million or 18% versus last year.

Cash earnings per share(4) for the last twelve months was $3.34—an increase of $0.79 as compared to the prior 12-month time period. The company believes cash earnings per share is a meaningful metric given the current $1.1 billion accumulated tax loss carryforward and the net depreciation and amortization impacts relating to fresh-start accounting. The first quarter reported loss per share of $2.11 was an improvement of $0.56 per share as compared to the first quarter 2011.

Net Debt(5) as of March 31, 2012 was $887 million, compared to $726 million as of December 31, 2011. In the first quarter the company invested $36 million in new capital, net of property insurance recoveries, paid $33 million in dividends, or $0.60 per common share, and repurchased $44 million or 970 thousand shares of its stock.

(3)          “Adjusted EBITDA”, a non-GAAP measure, is defined as the Company’s consolidated income (loss) from continuing operations: (i) excluding the cumulative effect of changes in accounting principles, fresh start accounting valuation adjustments, discontinued operations, income tax expense or benefit, reorganization items, restructure costs, other income or expense, gain or loss on early extinguishment of debt, equity in income or loss of investees, interest expense (net), amortization, depreciation, stock-based compensation, gain or loss on disposal of assets, interests of third parties in the Adjusted EBITDA of properties that are less than wholly owned by the Company (consisting of Six Flags Over Georgia, Six Flags Over Texas, Six Flags White Water Atlanta and Six Flags Great Escape Lodge & Indoor Waterpark (the “Lodge”), and (ii) plus the Company’s share of the Adjusted EBITDA of dick clark productions, inc.  The Company believes that Adjusted EBITDA provides useful information to investors regarding the Company’s operating performance and its capacity to incur and service debt and fund capital expenditures.  The Company believes that Adjusted EBITDA is useful to investors, equity analysts and rating agencies as a measure of the Company’s performance.  The Company uses Adjusted EBITDA in its internal evaluation of operating effectiveness and decisions regarding the allocation of resources.  In addition, Adjusted EBITDA is approximately equal to “Parent Consolidated Adjusted EBITDA” as defined in the Company’s secured credit facilities, except that Parent Consolidated Adjusted EBITDA excludes Adjusted EBITDA from equity investees that is not distributed to the Company in cash on a net basis and has limitations on the amounts of certain expenses that are excluded from the calculation.  Adjusted EBITDA is not defined by GAAP and should not be considered in isolation or as an alternative to net income (loss), income (loss) from continuing operations, net cash provided by (used in) operating, investing and financing activities or other financial data prepared in accordance with GAAP or as an indicator of the Company’s operating performance.  Adjusted EBITDA as defined herein may differ from similarly titled measures presented by other companies.
