CEO Commentary

“Our second quarter and first-half results reflect meaningful progress advancing the strategic priorities we established at the beginning of the year to strengthen the business," said John Reilly, Six Flags President and CEO. "Our more focused operating portfolio generated higher attendance, net revenues and Adjusted EBITDA, demonstrating that our portfolio actions and performance improvement initiatives are delivering improved financial results. Additionally, season pass and membership sales increased and our active pass base expanded during the second quarter, reinforcing our conviction that we are taking the right steps to build a stronger, more predictable business as we enter the most important part of our operating season.

"Our commercial strategy - designed to build a larger, more engaged guest community and create greater long-term value from each guest relationship, demonstrated its effectiveness by delivering tangible results in the second quarter," Reilly continued. "Guests continue to respond favorably to our flexible, benefit-rich season pass and membership offerings, with season-to-date pass sales increasing 7% and our active pass base growing 6% on a Same-Park Basis. We are also seeing encouraging demand for higher-tier passes and our expanded membership offerings, reflecting the value guests place on greater access and flexibility. Together, these initiatives strengthen recurring revenue, enhance visibility into future demand, and support stronger attendance and financial performance over time.

"We are strengthening park-level accountability, sharpening commercial execution, and maintaining a disciplined approach to capital allocation," Reilly added. "With the divestiture of seven non-core parks complete, we are focusing our resources on parks with the highest returns. These actions are building a stronger operating company with greater long-term earnings potential. While important work remains, the second quarter results and leading indicators give us increasing confidence in the operating priorities we have established.”

Summarized Second Quarter 2026 Results

Unless otherwise noted, the discussion below compares the performance of the Company's current operating portfolio, which excludes the results of the parks sold and closed. Same-Park Basis comparisons are presented as supplemental information. Management believes Same-Park Basis information is meaningful to help evaluate operating performance related only to the portfolio of parks that were owned and operated by Six Flags during the comparable periods and uses it for this purpose.

Net revenues. On a Reported Basis, the Company's parks generated net revenues of $865 million, a decrease of $65 million, or 7%, compared with $930 million in the second quarter of 2025. On a Same-Park Basis, the Company’s parks generated net revenues of $864 million, an increase of $20 million, or 2.4%, compared with $844 million in the second quarter of 2025. The increase in Same-Park Basis net revenues was driven primarily by 4% higher attendance, including a 10% increase in season-pass visitation, and continued strength in food and extra-charge spending per visit. These benefits were partially offset by lower admissions per capita spending(2), an earlier spring break season falling in this year's first quarter versus last year's second quarter, and approximately 3% fewer operating days.

Attendance and operating days. Attendance on a Reported Basis decreased 1.1 million visits, or 7%, compared with the second quarter of 2025. Attendance on a Same-Park Basis increased 449,000 visits, or 4%, compared with the second quarter of 2025. Attendance growth on a Same-Park Basis was supported primarily by increased season pass visitation, reflecting continued strength in the Company's season pass and membership programs across the portfolio. Operating days for the current operating portfolio totaled 1,615, compared with 1,659 operating days for the same parks in the prior-year period.

Per capita spending. Per capita spending on a Reported Basis was $62.89, an increase of $0.43, or 1%, compared with $62.46 in the prior-year period. Per capita spending on a Same-Park Basis was $62.88, a decline of $0.50, or 1%, compared with $63.38 in the prior-year period. The modest decline in per capita spending on a Same-Park Basis primarily reflected lower admissions per capita spending associated with expanded season pass benefits and increased cross-park visitation, partially offset by continued strength in guest spending on food, extra-charge attractions and other in-park offerings. Paid admission pricing remained stable year over year, while guests continued to trade up to higher-tier season pass products that provide greater access and flexibility. Management believes its initiatives support higher attendance and increased long-term earnings potential despite modest pressure on admissions per capita spending.

Operating costs and expenses. Operating costs and expenses remained well controlled despite higher attendance and guest activity during the quarter. On a Reported Basis, operating expenses decreased $61 million, and selling, general and administrative expense increased $1 million. On a Same-Park Basis, operating expenses increased by only $1 million compared with the prior-year period, as higher maintenance activity, as well as smaller increases in credit card fees, live entertainment costs and utility expenses, were largely offset by lower full-time wage expense and related benefits. Selling, general and administrative expense on a Same-Park Basis also remained well controlled, increasing only $3 million while continuing to support the Company's commercial initiatives and operating priorities. Selling, general and administrative expense on a Same-Park Basis increased due to full-time wages, which was primarily due to an increase in equity compensation and severance costs, and higher consulting and legal costs, both of which were offset by lower advertising costs. The combination of revenue growth and disciplined expense management resulted in stronger operating leverage, allowing a larger portion of incremental revenues to translate into higher earnings during the quarter.

Adjusted EBITDA. The Company’s parks generated Adjusted EBITDA of $243 million in both periods on a Reported Basis. On a Same-Park Basis, the Company's parks generated Adjusted EBITDA of $249 million, an increase of $16 million, or 7%, compared with $233 million in the second quarter of 2025. The improvement demonstrates stronger performance from the current operating portfolio. See the attached table for a reconciliation of net loss to Adjusted EBITDA.

Season Pass, Membership and Active Pass Base Progress

During the second quarter, the Company continued to build momentum in its season pass and membership programs, supported by a more differentiated product architecture, expanded regional and all-park access available with certain products, improved marketing execution, and a more coordinated approach to guest acquisition and retention.

•The active pass base increased 6% compared with the same time last year on a Same-Park Basis. Management views the number of guests eligible to visit the parks as an important leading indicator of attendance and a source of greater visibility into demand during the balance of the season.

•Sales mix continued to shift toward higher-tier pass products, reflecting guest response to the added access and enhanced benefits available with those offerings. The mix improvement supports higher-value guest relationships without relying solely on lower headline pricing.

•Membership participation continued to expand during the quarter. Member counts beyond their initial 12-month term exceeded the prior-year level at a higher average price, and the Company expanded its membership model to six additional parks in June 2026. Membership provides guests with a lower upfront purchase commitment while building the Company’s recurring-revenue base and supporting continued growth in the active pass base.

•Marketing investment produced improved acquisition and conversion efficiency during the quarter, supporting growth in pass sales and the active pass base while improving the economic return on guest acquisition spending.

The Company also introduced several major thrill rides, attractions and entertainment offerings during the quarter. These investments are designed to strengthen the guest proposition, support visitation and improve the return generated by the Company’s established park base.

Balance Sheet and Liquidity Highlights

The Company continued to strengthen its balance sheet during the first six months of 2026 through improved operating cash flow, disciplined capital spending, and the use of proceeds from previously announced portfolio transactions to reduce outstanding borrowings. The Company also reduced borrowings under its revolving credit facility and maintained substantial available capacity at quarter-end. Reducing leverage remains an essential financial priority.

As of June 28, 2026, the Company reported the following:

•Total deferred revenue of $431 million. On a Reported Basis, total deferred revenue decreased $30 million. On a Same-Park Basis, total deferred revenue increased $8 million, or 2%, compared with the prior year, supported by growth in membership and advance sales.

•Cash and cash equivalents of $135 million.

•Total liquidity of $837 million, including $703 million available under the Company’s revolving credit facility.

•Net debt(3) totaled $4.9 billion, calculated as total debt of $5.0 billion (before debt issuance costs and acquisition fair value layers) less cash and cash equivalents of $135 million.

Footnotes:

(1) Adjusted EBITDA is not a measurement computed in accordance with GAAP. Management believes Adjusted EBITDA is a meaningful measure of park-level operating profitability and uses it for measuring returns on capital investments, evaluating potential acquisitions, determining awards under incentive compensation plans, and calculating compliance with certain loan covenants. For additional information regarding Adjusted EBITDA, including how the Company defines and uses this measure, see the attached reconciliation table and related footnotes.

(2) Per capita spending, admissions per capita spending, in-park product per capita spending, and out-of-park revenues are non-GAAP financial measures. See the attached reconciliation table and related footnote for the calculation of these metrics. These metrics are used by management as major factors in significant operational decisions as they are primary drivers of financial and operational performance, measuring demand, pricing, and consumer behavior.

(3) Net debt is a non-GAAP financial measure. See the attached reconciliation table and related footnote for the calculation of net debt. Net debt is used by the Company and investors to monitor leverage, and management believes it is meaningful for this purpose.

(1) Consists of integration costs related to the merger between legacy Cedar Fair and legacy Six Flags (the "merger"), including third-party consulting costs, costs to integrate information technology systems, integration team salaries and benefits, retention bonuses, maintenance costs to update Former Six Flags parks to Cedar Fair standards and certain legal costs. These costs are added back to net loss to calculate Modified EBITDA and Adjusted EBITDA as defined in the Company's credit agreement.

(2) Consists of severance and related employer taxes and benefits. Certain employees, including certain executive level employees, were terminated as part of executive leadership transitions, as well as post-merger productivity and efficiency efforts.

(3) Consists of certain costs as defined in the Company's credit agreement. These costs are added back to net loss to calculate Modified EBITDA and Adjusted EBITDA and include certain legal and consulting expenses; certain costs at the sold and closed parks; certain recruiting and relocation costs; cost of goods sold recorded to align inventory standards following the merger; Mexican VAT taxes on intercompany activity; and contract termination costs. This balance also includes unrealized gains and losses on pension assets and short-term investments.

(4) Modified EBITDA represents earnings before interest, taxes, depreciation, amortization, other non-cash items, and adjustments as defined in the Company's credit agreement. Adjusted EBITDA represents Modified EBITDA less net loss attributable to non-controlling interests. Management includes both measures to disclose the effect of non-controlling interests. Management believes Modified EBITDA and Adjusted EBITDA are meaningful measures of park-level operating profitability, and uses them for measuring returns on capital investments, evaluating potential acquisitions, determining awards under incentive compensation plans, and calculating compliance with certain loan covenants. Adjusted EBITDA is widely used by analysts, investors and comparable companies in the industry to evaluate operating performance on a consistent basis, as well as more easily compare results with those of other companies in the industry. Modified EBITDA and Adjusted EBITDA are provided as supplemental measures of the Company's operating results and are not intended to be a substitute for operating income, net income or cash flows from operating activities as defined under generally accepted accounting principles. In addition, Modified EBITDA and Adjusted EBITDA may not be comparable to similarly titled measures of other companies.

(6) Same-Park Basis compares the performance of the Company's current operating portfolio, which excludes the results of (1) seven parks Six Flags sold to EPR Properties prior to the start of 2026 park operations, and (2) a combined amusement/water park located in Bowie, Maryland, where park operations were discontinued following the end of its 2025 operating season. Same-Park Basis comparisons are presented as supplemental information. Management believes Same-Park Basis information is meaningful to help evaluate operating performance related only to the portfolio of parks that were owned and operated by Six Flags during the comparable periods and uses it for this purpose.

(1) Per capita spending is calculated as revenues generated within the Company's amusement parks and separately gated outdoor water parks along with related parking revenues and online transaction fees charged to customers (in-park revenues), divided by total attendance. Admissions per capita spending is calculated as revenues generated for admission to the Company's amusement parks and separately gated water parks along with related parking revenues and online transaction fees charged to customers (in-park admissions revenues) divided by total attendance. In-park product per capita spending is calculated as all other revenues generated within the Company's amusement parks and separately gated water parks, including food and beverage, merchandise, games and extra-charge offerings (in-park product revenues) divided by total attendance. Out-of-park revenues are defined as revenues from resorts, out-of-park food and merchandise locations, sponsorships, international agreements and all other out-of-park operations. Beginning in the fourth quarter of 2025, the Company renamed in-park per capita spending to per capita spending and renamed per capita spending on in-park products to in-park product per capita spending. The methodology for calculating these metrics remains unchanged, and therefore any previously reported metrics that are renamed to corresponding metrics remain unchanged.

In-park revenues, per capita spending, in-park admissions revenues, admissions per capita spending, in-park product revenues, in-park product per capita spending, and out-of-park revenues are non-GAAP measures. These metrics are used by management as major factors in significant operational decisions as they are primary drivers of financial and operational performance, measuring demand, pricing, and consumer behavior. Reconciliations of in-park revenues, including in-park admissions revenues and in-park product revenues, and out-of-park revenues to net revenues for the periods presented on a Reported Basis and on a Same-Park Basis are included in the tables below.
