Six Flags Reports 5 Percent Revenue Growth, 7 Percent Guest Spending Growth, and 20 Percent Adjusted EBITDA Growth in Second Quarter

Company Sets New Long-Term Profit Target

Grand Prairie, TX — July 25, 2011 — Six Flags Entertainment Corporation (NYSE: SIX) today announced second quarter 2011 revenue increased 5 percent over the prior year period to $339 million and Adjusted EBITDA(1) increased 20 percent to $114 million. For the first six months of the year, revenue grew 6 percent to $400 million and Adjusted EBITDA grew 86 percent to $65 million. Higher admissions revenue, stronger guest spending in the parks and lower cash operating costs contributed to the company’s improved profitability for both the three- and six-month periods ended June 30, 2011. For the twelve months ended June 30, 2011, Adjusted EBITDA was $325 million.

“I am very pleased with our team’s execution,” said Jim Reid-Anderson, Chairman, President and CEO. “We registered record guest satisfaction scores in the quarter and delivered improvements in all key financial metrics including revenue, profitability and cash flow. We are successfully implementing a multi-year strategy to create value for our shareholders.”

Revenue growth in the second quarter was driven by a $15 million or 9 percent increase in admissions revenue and a $5 million or 4 percent increase in in-park revenue, offset by a $3 million decline in revenue related primarily to sponsorships and international licensing. Total revenue per capita for the second quarter of 2011 was $41.12, compared to $39.00 for the second quarter of 2010, an increase of $2.12 or 5 percent.

Admissions revenue per capita of $22.28 increased $1.88 or 9 percent, in-park revenue per capita of $17.08 increased $0.62 or 4 percent, and overall guest spending per capita increased $2.50 or 7 percent. During the second quarter, guest attendance grew slightly to 8.2 million.

Revenue growth in the first six months of 2011 was driven by an $18 million or 9 percent increase in admissions revenue and a $7 million or 5 percent increase in in-park revenue, offset by a $4 million decline in revenue related primarily to sponsorships and international licensing. Total revenue per capita for the first half of 2011 was $42.04 as compared to $39.85 for the first six months of 2010, an increase of $2.19 or 5 percent. Admissions revenue per capita of $22.06 increased $1.86 or 9 percent, in-park revenue per capita of $17.19 increased $0.73 or 4 percent, and overall guest spending per capita increased $2.59 or 7 percent. During the first six months of 2011, guest attendance grew slightly to 9.5 million.

Cash operating costs during the second quarter 2011 of $208 million were $5 million lower than the same period in 2010 primarily due to a reduction in cash compensation costs. For the first six months of 2011 cash operating costs of $321 million were $12 million or 3 percent lower than the same period in 2010 primarily due to lower cash compensation and marketing costs.

The second quarter 2011 Modified EBITDA(2) margin improved 415 basis points over the same period in 2010 to 38.6 percent. For the twelve months ended June 30, 2011, Modified EBITDA margin improved 760 basis points over the twelve-month period ended June 30, 2011 to 35.5 percent.

Cash earnings per share(3) for the twelve months ended June 30, 2011 was $3.11. Since the company emerged from Chapter 11 on April 30, 2010 with a new capital structure, the prior period cash earnings per share figure is not meaningful.

Free Cash Flow(4), which for the company is defined as Adjusted EBITDA less capital expenditures, cash interest and cash taxes, was $61 million in the second quarter, and included $37 million of capital spending.

Net Debt(5) as of June 30, 2011 was $829 million compared to $896 million as of March 31, 2011—an improvement of $67 million. During the second quarter, the company paid $2 million in dividends and made a $30 million arbitration settlement payment, including associated interest and fees, relating to the company’s former CFO. In addition, the company repurchased approximately $22 million or 574,000 shares of its stock at an average purchase price of $38.26 under a three-year, $60 million plan approved by the board of directors in February 2011. During the first six months of 2011, the company repurchased approximately $42 million or 1,166,000 shares of its stock at an average purchase price of $35.60.

The company had $142 million of cash on hand as of June 30, 2011 and a net debt to last-twelve-months Adjusted EBITDA ratio of 2.6 times.

During the second quarter the company implemented a two-for-one stock split.

About Six Flags Entertainment Corporation

Six Flags Entertainment Corporation is the world’s largest regional theme park company with 19 parks across the United States, Mexico and Canada. Six Flags Over Texas, the company’s flagship location, is celebrating its 50th anniversary season in 2011.

Fresh Start Reporting

In connection with the company’s emergence from Chapter 11 on April 30, 2010 and the application of fresh start reporting upon emergence in accordance with FASB ASC Topic 852, “Reorganizations”, the results for the three- and six-month periods ended June 30, 2011 and the two-month period ended June 30, 2010, respectively (the company is referred to during such periods as the “Successor”) and the results for the one- and four-month periods ended April 30, 2010 (the company is referred to during such periods as the “Predecessor”) are presented separately. This presentation is required by United States generally accepted accounting principles (“GAAP”), as the Successor is considered to be a new entity for financial reporting purposes, and the results of the Successor reflect the application of fresh-start reporting. Accordingly, the company’s financial statements after April 30, 2010, are not comparable to its financial statements for any period prior to its emergence from Chapter 11. For illustrative purposes in this earnings release, the company has combined the Successor and Predecessor results to derive combined results for the three- and six-month periods ended June 30, 2010. However, because of various adjustments to the consolidated financial statements in connection with the application of fresh-start reporting, including asset valuation adjustments and liability adjustments, the results of operations for the Successor are not comparable to those of the Predecessor. The financial information accompanying this earnings release provides the Successor and the Predecessor GAAP results for the applicable periods,

along with the combined results described above. The company believes that subject to consideration of the impact of fresh start reporting, the combined results provide meaningful information about revenues and costs, which would not be available if the current year periods were not combined to accommodate analysis.

Forward Looking Statements

The information contained in this release, other than historical information, consists of forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act. These statements may involve risks and uncertainties that could cause actual results to differ materially from those described in such statements. These risks and uncertainties include, among others, (i) the adequacy of cash flows from operations, available cash and available amounts under our credit facilities to meet our future liquidity needs, (ii) our ability to improve operating results by implementing strategic cost reductions, and organizational and personnel changes without adversely affecting our business, (iii) our operations and results of operations, and (iv) the risk factors or uncertainties listed from time to time in the company’s filings with the Securities and Exchange Commission (“SEC”). In addition, important factors, including factors impacting attendance, local conditions, events, disturbances and terrorist activities, risk of accidents occurring at the company’s parks, adverse weather conditions, general financial and credit market conditions, economic conditions (including consumer spending patterns), competition, pending, threatened or future legal proceedings and other factors could cause actual results to differ materially from the company’s expectations. Although the company believes that the expectations reflected in such forward-looking statements are reasonable, it can give no assurance that such expectations will be realized and actual results could vary materially. Reference is made to a more complete discussion of forward-looking statements and applicable risks contained under the captions “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors” in the company’s Annual and Quarterly Reports on Forms 10-K and 10-Q, and its other filings and submissions with the SEC, each of which are available free of charge on the company’s investor relations website at www.sixflags.com/investors and on the SEC’s website at www.sec.gov.

(2)  See Note 3 to the following financial statements for a discussion of Modified EBITDA and its reconciliation to net income (loss).

(3)       “Cash earnings per share”, which is defined as Free Cash Flow divided by the weighted average shares outstanding, is not a U.S. GAAP defined measure. The company believes this measure provides meaningful profitability metrics, given current accumulated tax loss carryforwards and the net depreciations/amortization impacts relating to the revaluation of assets in connection with the company’s emergence from Chapter 11.

Balance Sheet Data

(In Thousands)

(1)  Revenues and expenses of international operations are converted into U.S. dollars on an average basis as provided by GAAP.

(2)  Previously reported amounts have changed on the Predecessor financials.  These changes are primarily related to classifications between income tax expense and reorganization items, net, and a related increase in predecessor goodwill. There were no changes to net income, earnings per share or total stockholders’ equity / (deficit).

(3)  Amounts recorded as valuation adjustments and included in reorganization items for the month of April 2010 that would have been included in Modified EBITDA and Adjusted EBITDA, had fresh start reporting not been applied.  Balance consists primarily of discounted insurance reserves that will be accreted through the statement of operations each quarter through 2018.

(4)  “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 operations of partnerships, 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.

“Modified EBITDA”, a non-GAAP measure,  is defined as Adjusted EBITDA plus the interests of third parties in the Adjusted EBITDA of the properties that are less than wholly owned (consisting of Six Flags Over Georgia, Six Flags White Water Atlanta, Six Flags Over Texas, the Lodge plus the Company’s interest in the Adjusted EBITDA of dick clark productions, inc.).  The Company believes that Modified EBITDA is useful in the same manner as Adjusted EBITDA, with the distinction of representing a measure that can be more readily compared to other companies that do not have interests of third parties in any of their properties or equity investments.  Modified 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.  Modified EBITDA as defined herein may differ from similarly titled measures presented by other companies.

(5)  Represents interests of third parties in the Adjusted EBITDA of Six Flags Over Georgia, Six Flags Over Texas, Six Flags White Water Atlanta and the Lodge, plus the Company’s interest in the Adjusted EBITDA of dick clark productions, inc., which are less than wholly owned.

(6)  Free Cash Flow, a non-GAAP measure, is defined as Adjusted EBITDA less (i) cash paid for interest expense net of interest income receipts, (ii) capital expenditures net of property insurance recoveries (which includes $8.0 million of proceeds, in the third quarter of 2010, related to the final settlement of an insurance claim for Six Flags New Orleans), and (iii) cash taxes.  The Company has excluded from the definition of Free Cash Flow the $70.3 million in post-petition interest paid to the holders of the Six Flags Operations notes that were extinguished in April 2010, the deferred financing costs related to the Company’s new debt of $41.8 million incurred in the second quarter of 2010, and the deferred financing costs related to the Company’s debt refinancing of $11.8 million incurred in the fourth quarter of 2010, due to the unusual nature of these items.  The Company believes that Free Cash Flow is useful to investors, equity analysts and rating agencies as a performance measure.  The Company uses Free Cash Flow in its internal evaluation of operating effectiveness and decisions regarding the allocation of resources.  Free Cash Flow 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.  Free Cash Flow as defined herein may differ from similarly titled measures presented by other companies.
