Confidence: high Filing date: 2026-05-07 Report date: 2026-03-29 ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS The following discussion and analysis is intended to facilitate an understanding of the Company's business and results of operations and should be read in conjunction with the unaudited consolidated financial statements and the related notes thereto included elsewhere in this Quarterly Report on Form 10-Q. This discussion should also be read in conjunction with the Company's consolidated financial statements and related notes thereto, the "Management's Discussion and Analysis of Financial Condition and Results of Operations" section of the Company's Annual Report on Form 10-K for the year ended December 31, 2025. Business Overview: The Company is North America's largest regional amusement park operator with 21 amusement parks, 14 separately gated water parks and eight resorts as of the filing date for this Form 10-Q. See Note 4 to the accompanying unaudited consolidated financial statements for additional information regarding the definitive agreements to sell seven parks. Of the 35 amusement and water parks, 31 are located in the United States, two are located in Mexico and two are located in Canada. The parks generate revenues from sales of (1) admission to amusement parks and water parks, (2) food, merchandise and games both inside and outside the parks, and (3) accommodations, extra-charge products, and other revenue sources. The Company's principal costs and expenses, which include salaries and wages, operating and maintenance supplies, insurance, advertising, utilities and lease payments, are relatively fixed for a typical operating season and do not vary significantly with attendance. The Company's principal costs and expenses have recently been impacted by increased wage rates, driven both by market rates and statutory rates, higher insurance costs, and general inflation affecting the costs of inventory, services and supplies. The Company acquires rides, attractions, inventory, and supplies from foreign countries, of which many rides and attractions require specialized manufacturing. Changes in import tariffs and trade policies have resulted and may continue to result in increased costs. Potential market disruptions could result in the inability to acquire certain goods timely or at all. The Company's operations are seasonal. Approximately 70% of annual attendance and revenue occurred during the second and third quarters during fiscal year 2025. As a result, a substantial portion of the Company's revenues are expected to be generated from Memorial Day through Labor Day with the major portion concentrated during the peak vacation months of July and August. The fall season is also important to the Company's operations due to the popularity of fall and Halloween events. Consequently, when adverse conditions or events occur during the operating season, particularly during the peak vacation months of July and August or the important fall season (for example, the extreme weather events that negatively impacted the Company's results during the second quarter of 2025), there is only a limited period of time during which the impact of those conditions or events can be mitigated. Accordingly, the timing of such conditions or events can have a disproportionate adverse effect upon revenues. Management reviews operating results, evaluates performance and makes operating decisions, including allocating resources, on a park-by-park basis. Discrete financial information and operating results are prepared at the individual park level for use by the CEO, who is the Chief Operating Decision Maker ("CODM"), as well as by the Chief Financial Officer, the Chief Operating Officer and Senior Vice Presidents. The Company operates within a single reportable segment of amusement and water parks with accompanying resort facilities. The following operational measures are key performance metrics in the Company's managerial and operational reporting. They are used as major factors in significant operational decisions as they are the primary drivers of financial and operational performance, measuring demand, pricing and consumer behavior. 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. 24 Table of Contents Attendance is defined as the number of guest visits to amusement parks and separately gated outdoor water parks. Attendance is driven by various factors, including new rides and product offerings, guest satisfaction, weather, pricing, advertising programs, perceived safety of the parks and economic conditions. Major attendance categories include single-day attendance related to a single-day ticket, including sales to groups, season pass attendance related to season passes that are valid for an operating season, and membership attendance related to memberships that are valid for a 12-month non-cancelable period and until the guest cancels thereafter. 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. Per capita spending is driven by similar factors to attendance and is also impacted by the length of stay of the Company's guests. Major per capita spending categories include admission, food and beverage, merchandise, games and extra-charge products. Extra-charge products include premium benefit offerings such as front-of-line products. 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. Beginning in the fourth quarter of 2025, we renamed in-park per capita spending to per capita spending, and we 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. 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. Out-of-park revenues are primarily driven by attendance to the parks and can increase length of stay at the Company's properties as guests purchase hotel rooms and visit out-of-park food and merchandise locations. In addition, higher attendance levels enable the Company to develop long-term corporate sponsorships and co-marketing relationships with well-known national and regional brands. The Company manages Six Flags Qiddiya City and Aquarabia Qiddiya City in Saudi Arabia and receives fees for exclusivity, brand licensing rights, and design, development and management services. Despite regional tensions in the Middle East, both parks continue to operate. The following table presents net revenues disaggregated by in-park revenues, including in-park admissions revenues and in-park product revenues, and out-of-park revenues less amounts remitted to outside parties under concessionaire arrangements (concessionaire remittances) for the periods presented. Three months ended (In thousands) March 29, 2026 March 30, 2025 In-park admissions revenues $ 113,441  $ 106,311  In-park product revenues 88,977  78,004  In-park revenues 202,418  184,315  Out-of-park revenues 28,799  23,916  Concessionaire remittances (5,590) (6,174) Net revenues $ 225,627  $ 202,057  Outlook: The near-term operational priorities of the Company focus on accelerating profitability and strengthening the balance sheet. Management intends to drive profitability by offering a higher value proposition to the guest that stimulates incremental demand while simultaneously implementing strategic cost management strategies and organizational improvements. Management plans to simplify product offerings, optimize pricing on a park-by-park basis, tailor marketing strategies to the unique attributes of each park, leverage consumer-facing technologies to strengthen communication channels with guests, adopt innovative processes designed to unlock incremental cost efficiencies, optimize park cost structures toward the performance profile of top performing parks and build the necessary capabilities, systems and operating models to support scalable and sustained execution of these strategies. To strengthen the balance sheet, management aims to benefit from the incremental cash flow that is expected to be produced by these profitability initiatives while also undergoing portfolio optimization, including the recent 2026 Sale Transaction and the sale of the property on which the former amusement and water park in Bowie, Maryland was located. Portfolio optimization is expected to allow management to narrow its focus, reduce ongoing capital expenditure requirements, and limit exposure to liabilities. Together, these actions are intended to create a more focused, resilient and financially flexible organization positioned for long-term success. 25 Table of Contents Critical Accounting Estimates: Management’s Discussion and Analysis of Financial Condition and Results of Operations is based upon the unaudited consolidated financial statements of the Company, which were prepared in accordance with accounting principles generally accepted in the United States of America. These principles require management to make judgments, estimates and assumptions during the normal course of business that affect the amounts reported in the unaudited consolidated financial statements. Actual results could differ significantly from those estimates under different assumptions and conditions. Management believes that judgment and estimates related to the following critical accounting policies could materially affect the unaudited consolidated financial statements: •Business Combinations •Impairment of Long-Lived Assets •Goodwill and Other Intangible Assets •Self-Insurance Reserves •Revenue Recognition •Income Taxes During the first quarter of 2026, there were no changes to the above critical accounting policies from those previously disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2025. As discussed in Note 5 to the accompanying unaudited consolidated financial statements, certain Former Six Flags and Schlitterbahn reporting units experienced a decline in estimated future cash flows during 2025 as a result of revenue and earnings not meeting expectations through the more seasonally significant third quarter, and the Company experienced a more significant, sustained decline in its share price through the third quarter of 2025 when compared to industry peers. In connection with the preparation of the financial statements for the third quarter of 2025, which includes the peak summer months of July and August and by itself can account for nearly half of full year attendance and over half of full year earnings, management had greater clarity regarding performance trends and full year results. As a result, a triggering event occurred and impairment charges were recognized during the third quarter of 2025. Valuation assumptions about future performance could adversely change and result in further goodwill and/or trade name impairment that would have a material effect on the Company's financial posi [Excerpt truncated for page length; source filing is linked above.] ## Latest 10-K MD&A Extracted between Item 7 and the next Item 7A/8 heading after HTML sanitization. Confidence: high ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS. Merger Agreement with Former Six Flags On July 1, 2024, the previously announced merger of equals transaction contemplated by the Merger Agreement, by and among CopperSteel HoldCo, Inc., Cedar Fair, Former Six Flags and Copper Merger Sub, was completed. Upon the consummation of the Mergers, the separate legal existences of each of Copper Merger Sub, Cedar Fair and Former Six Flags ceased, and the Combined Company changed its name to “Six Flags Entertainment Corporation”. The Combined Company trades on the New York Stock Exchange under the ticker symbol "FUN". References to the "Partnership," "Cedar Fair," or "Former Cedar Fair" are to Cedar Fair prior to the Mergers, and references to the "Combined Company" and the "Company" are to Cedar Fair, Former Six Flags and Copper Merger Sub after giving effect to the Mergers. The Mergers were entered into to create a leading amusement park operator with an expanded and diversified property portfolio, improved guest experience utilizing the complementary operating capabilities of Cedar Fair and Former Six Flags, and the opportunity for accelerated investment in the Cedar Fair and Former Six Flags properties with the cash flows of the Combined Company. For additional information, see the Explanatory Note in this Annual Report on Form 10-K and Note 2 to the accompanying consolidated financial statements. The Six Flags Merger was accounted for as a business combination using the acquisition method of accounting. Former Cedar Fair has been determined to be the accounting acquirer and the predecessor for financial statement purposes. Accordingly, unless indicated otherwise, financial results and disclosures within this Management's Discussion and Analysis as of December 31, 2025, as of December 31, 2024, and for the year ended December 31, 2025 reflect the Combined Company's operations. Financial results and disclosures for the year ended December 31, 2024 include only Cedar Fair's results before giving effect to the Mergers through June 30, 2024 and include Combined Company results from July 1, 2024 through December 31, 2024. Business Overview The Company is North America's largest regional amusement park operator with 26 amusement parks, 15 separately gated water parks and nine resorts. Of the 41 amusement and water parks, 37 are located in the United States, two are located in Mexico and two are located in Canada.

Critical Accounting Estimates Management's Discussion and Analysis of Financial Condition and Results of Operations is based upon the consolidated financial statements, which were prepared in accordance with accounting principles generally accepted in the United States of America. These principles require management to make judgments, estimates and assumptions during the normal course of business that affect the amounts reported in the Consolidated Financial Statements and related notes. The following discussion addresses critical accounting estimates, which are those that are most important to the portrayal of the Company's financial condition and operating results or involve a higher degree of judgment and complexity (see Note 1 to the accompanying consolidated financial statements for a complete discussion of significant accounting policies). Application of the critical accounting policies described below involves the exercise of judgment and the use of assumptions as to future uncertainties, and as a result, actual results could differ from these estimates and assumptions. 24 Table of Contents Business Combinations Business combinations are accounted for under the acquisition method of accounting. The amounts assigned to the identifiable assets acquired and liabilities assumed in connection with acquisitions are based on estimated fair values as of the date of the acquisition, with the remainder, if any, recorded as goodwill. The fair values are determined by management, taking into consideration information supplied by the management of the acquired entities, valuations supplied by independent appraisal experts and other relevant information. The determination of fair values requires significant judgment by management. During the measurement period, which may be up to one year from the acquisition date, adjustments to the assets acquired and liabilities assumed may be recorded with the corresponding offset to goodwill. Upon the measurement period's conclusion or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the consolidated statement of operations and comprehensive (loss) income. Adjustments during the measurement period could have a material effect on the Company's financial position and results of operations in future periods. Acquisition-related expenses are recognized separately from the business combination and expensed as incurred. Impairment of Long-Lived Assets Long-lived assets, including property and equipment, are reviewed for impairment upon the occurrence of events or changes in circumstances that would indicate that the carrying value of the assets may not be recoverable. In order to determine if an asset has been impaired, assets are grouped and tested at the lowest level for which identifiable, independent cash flows are available. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others: a significant decrease in the market price of a long-lived asset; a significant adverse change in the extent or manner in which a long-lived asset is being used or in its physical condition; a significant adverse change in legal factors or in the business climate; an accumulation of costs significantly in excess of the amount originally expected for the acquisition or construction of a long-lived asset; past, current or future operating or cash flow losses that demonstrate continuing losses associated with the use of a long-lived asset; and a current expectation that a long-lived asset will be sold or disposed significantly before the end of its previously estimated useful life. An impairment loss may be recognized when estimated undiscounted future cash flows expected to result from the use of the asset, including disposition, are less than the carrying value of the asset. The measurement of the impairment loss to be recognized is based on the difference between the fair value and the carrying amounts of the assets. Fair value is generally determined using a combination of a cost and market approach. Significant factors considered in the cost approach include replacement cost, reproduction cost, depreciation, physical deterioration, functional obsolescence and economic obsolescence of the assets. The market approach estimates fair value by utilizing market data for similar assets. The determination of whether an indicator of impairment has occurred and the estimation of undiscounted cash flows requires management to make significant estimates and consider an anticipated course of action as of the balance sheet date. Subsequent changes arising from changes in anticipated actions could impact the determination of whether impairment exists, the estimation of undiscounted cash flows and whether the effects could materially impact the consolidated financial statements. Goodwill and Other Intangible Assets Goodwill and other indefinite-lived intangible assets, including trade-names, are reviewed for impairment annually, or more frequently if indicators of impairment exist. A significant amount of judgment is involved in determining if an indicator of impairment has occurred. Such indicators may include, among others: a significant decline in expected future cash flows; a sustained, significant decline in equity price and market capitalization; a significant adverse change in legal factors or in the business climate; unanticipated competition; the testing for recoverability of a significant asset group within a reporting unit; and slower growth rates. The fair value of a reporting unit is established using an income (discounted cash flow) approach, a market approach, or a combination thereof. The income approach uses a reporting unit's projection of estimated operating results and discounted cash flows using a weighted-average cost of capital that reflects current market conditions. Estimated operating results are established using management's best estimates of economic and market conditions over the projected period including growth rates in revenues and costs, estimates of future expected changes in operating margins and cash expenditures. Other significant estimates and assumptions include terminal value growth rates, future estimates of capital expenditures and changes in future working capital requirements. A market approach estimates fair value by applying cash flow multiples to the reporting unit's operating performance. The multiples are derived from comparable publicly traded companies with similar operating and investment characteristics of the reporting units. It is possible that assumptions about future performance, as well as the economic outlook and related conclusions regarding valuation, could change adversely, which may result in additional impairment that would have a material effect on the Company's financial position and results of operations in future periods. As discussed in Note 5 to the accompanying consolidated financial statements, certain Former Six Flags and Schlitterbahn reporting units experienced a decline in estimated future cash flows during 2025 as a result of revenue and earnings not meeting expectations through the more seasonally significant third quarter, and the Company experienced a more significant, sustained decline in its share price through the third quarter when compared to industry peers. In connection with the preparation of the financial statements for the third quarter of 2025, which includes the peak summer months of July and August and by itself can account for nearly half of full year attendance and over half of full year earnings, management had greater clarity regarding performance trends and full year results. As a result, a triggering event occurred and impairment charges were recognized during the third quarter of 2025. Valuation assumptions about future performance could adversely change and result in further goodwill and/or trade name impairment that would have a material 25 Table of Contents effect on the Company's financial position and results of operations in future periods. Future valuation assumptions are dependent on numerous factors, including the Company's operating plans for fiscal year 2026 and future years, changes to the Company's long-term strategy and other market conditions. Self-Insurance Reserves Self-insurance reserves are recorded for the estimated amounts of guest and employee claims and related expenses incurred each period. Reserves are established for both identified claims and incurred but not reported ("IBNR") claims and are recorded when claim amounts become probable and estimable. Reserves for identified claims are based upon historical claim experience and third-party estimates of settlement costs. Reserves for IBNR claims are based upon claims data history. Self-insurance reserves are periodically reviewed for changes in facts and circumstances and adjustments are made as necessary. The ultimate cost for identified claims can be difficult to predict due to the unique facts and circumstances associated with each claim. In addition, management has observed a pattern of increasing litigation and settlement costs in recent years, including exceptionally high verdicts or settlements. Revenue Recognition Revenues are generated from sales of (1) admission to amusement parks and water parks, (2) food, merchandise and games both inside and outside the parks, and (3) accommodations, extra-charge products, and other revenue sources. Most revenues are recognized on a daily basis based on actual guest spend at the properties. Revenues from multi-use products, including season-long products for admission, dining, beverage and other products and the first 12-month non-cancelable period for membership products, are recognized over the estimated number of uses expected for each type of product. The estimated number of uses is reviewed and may be updated periodically during the operating season prior to the ticket or product expiration. The number of uses is estimated based on historical usage adjusted for current period trends. In order to calculate revenue recognized on season-long products and the first 12-month non-cancelable period for membership products, management makes significant estimates regarding the estimated number of uses expected for season-long products, including during interim periods. Actual usage could materially differ from these estimates which could potentially result in an inappropriate amount of revenue recognized in a given period. Income Taxes The Company accounts for income taxes under the asset and liability method. Accordingly, deferred tax assets and liabilities are recognized for the future book and tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are determined using enacted tax rates expected to apply in the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax law is recognized in income at the time of enactment of such change in tax law. Any interest or penalties due for payment of income taxes are included in the provision for income taxes. A valuation allowance is recorded if, based on the weight of available evidence, it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. The need for this allowance is based on several factors including the ten-year carryforward period allowed for excess foreign tax credits, experience to date of foreign tax credit limitations, carryforward periods of state net operating losses, and management's long-term estimates of domestic and foreign source income. The Company evaluates its tax positions using a more-likely-than-not threshold, and those tax positions requiring recognition are measured at the largest amount of tax benefit that is greater than 50% likely of being realized upon effective settlement with a taxing authority that has full knowledge of all relevant information. There is inherent uncertainty in the estimates used to project the amount of foreign tax credit and state net operating loss carryforwards that are more likely than not to be realized, and the estimates used to evaluate uncertain tax positions. It is possible that future income projections, as well as the economic outlook and related conclusions regarding valuation allowances and uncertain tax positions could change, which may result in additional expense being recorded or may result in additional expense reductions, and which may have a material negative or positive effect on the reported financial position and results of operations in future periods. Results of Operations The Results of Operations section includes a discussion and comparison of 2025 and 2024 results. For a discussion regarding 2023 results, including comparisons of 2024 results to 2023 results, see "Management's Discussion and Analysis of Financial Condition and Results of Operations" within the Company's Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on March 3, 2025. 26 Table of Contents 2025 vs. 2024 The results for the year ended December 31, 2025 are not directly comparable with the results for the year ended December 31, 2024 because the year ended December 31, 2024 only includes the results of Former Six Flags operations from July 1, 2024 through December 31, 2024. The year ended December 31, 2025 included 5,738 operating days compared with 4,369 operating days for the year ended December 31, 2024, an increase of 1,369 operating days. There were 1,513 operating days for the six-month period ended June 29, 2025 at Former Six Flags parks. The offsetting 144 operating day decrease was primarily driven by the planned removal of lower-volume operating days from the 2025 operating calendar, including the removal of winter events at four parks. The following table presents key financial information for the Combined Company for the years ended December 31, 2025 and December 31, 2024: Increase (Decrease) December 31, 2025 December 31, 2024 $ % (Amounts in thousands, except for per capita and operating days) Net revenues $ 3,100,289  $ 2,708,926  $ 391,363  14.4  % Operating costs and expenses 2,429,353  2,019,781  409,572  20.3  % Depreciation and amortization 486,383  318,113  168,270  52.9  % Loss on retirement of fixed assets, net 40,670  18,064  22,606  125.1  % Loss on impairment of goodwill and other intangibles 1,518,099  42,462  1,475,637  N/M Loss on other assets 791  —  791  N/M Operating (loss) income $ (1,375,007) $ 310,506  $ (1,685,513) (542.8) % Other Data: Attendance 47,388  41,649  5,739  13.8  % Per capita spending $ 61.90  $ 61.31  $ 0.59  1.0  % Admissions per capita spending $ 33.41  $ 33.70  $ (0.29) (0.9) % In-park product per capita spending $ 28.49  $ 27.61  $ 0.88  3.2  % Out-of-park revenues $ 255,454  $ 232,415  $ 23,039  9.9  % Operating days 5,738  4,369  1,369  31.3  % Net loss margin (1) (50.0) % (7.6) % (42.4) % N/M    Not meaningful due to the nature of the expense line-item. (1)    Net loss margin is calculated as net loss divided by net revenues. For the year ended December 31, 2025, net revenues increased $391.4 million compared with 2024, which included the impact of $499.7 million in net revenues contributed by Former Six Flags operations during the six months ended June 29, 2025. The increase in net revenues reflected the impact of a 5.7 million-visit increase in attendance, the impact of a $0.59, or 1.0% increase in per capita spending and a $23.0 million increase in out-of-park revenues. The 5.7 million-visit increase in attendance included 7.8 million-visits at Former Six Flags parks during the six months ended June 29, 2025. The offsetting 2.1 million-visit decline in attendance was largely driven by a decline in attendance during the second and fourth quarters. The second quarter was impacted by inclement weather at Former Cedar Fair parks, particularly in the Midwest and which also resulted in fewer season pass sales, and fewer operating days primarily due to the planned removal of lower-volume operating days from the 2025 operating calendar. The fourth quarter was impacted by similar factors, including the removal of four winter events and less favorable weather than the prior fourth quarter. The $0.59 increase in per capita spending was due to higher per capita spending on in-park products driven by increased food and beverage and extra-charge spending somewhat offset by lower admissions per capita spending driven by a higher mix of season pass visitation as a percentage of total visitation. The $0.59 increase in per capita spending included a $0.30 increase in per capita spending due to the inclusion of the Former Six Flags parks during the six months ended June 29, 2025. The $23.0 million increase in out-of-park revenues was primarily due to $19.6 million contributed by Former Six Flags operations during the six months ended June 29, 2025, as well as higher sponsorship revenues. The increase in net revenues included a $4.2 million favorable impact of foreign currency exchange rates. Operating costs and expenses for the year ended December 31, 2025 increased $409.6 million compared with 2024. The increase in operating costs and expenses was the result of a $344.2 million increase in operating expenses, a $37.1 million increase in cost of goods sold and a $28.2 million increase in selling, general, and administrative ("SG&A") expenses. The $344.2 million increase in operating expenses was due to a $384.6 million increase related to Former Six Flags operations during the six months ended June 29, 2025 and increased utility costs of $6.9 million offset by $18.1 million of planned fewer seasonal labor hours, $14.0 million in lower full-time wages, and the impact of a $14.9 million increase to Former Cedar Fair's self-insurance reserves in the prior year (see Note 1 to the accompanying consolidated financial statements). The decrease in full-time wages was driven by a decrease in full-time head count related to recent post-merger productivity and efficiency efforts 27 Table of Contents and a reduction in expected bonus payments due to changes in expected Company performance partially offset by severance expense in the period. Cost of goods sold as a percentage of food, merchandise and games revenue increased 10 basis points ("bps"). The 10 bps increase included a non-recurring charge to cost of goods sold recorded to align inventory standards following the Mergers. The $28.2 million increase in SG&A expenses included $68.0 million of additional expenses related to Former Six Flags operations during the six months ended June 29, 2025 offset by a $75.7 million decrease in costs related to the Mergers. Excluding these factors, SG&A expense increased as a result of $20.1 million of higher technology costs, including integration related costs, $17.6 million in severance and integration-related wages and $5.6 million of higher employee benefits offset by an $18.8 million planned decrease in advertising costs. The increase in operating costs and expenses included a $1.3 million unfavorable impact of foreign currency exchange rates. Depreciation and amortization expense for the year ended December 31, 2025 increased $168.3 million compared with 2024, which was due to $155.5 million of depreciation expense attributable to Former Six Flags during the six months ended June 29, 2025, and the acceleration of depreciation related to the assets at a combination amusement and water park located in Bowie, Maryland, which closed at the end of the 2025 operating season. The loss on retirement of fixed assets for both periods and the loss on other assets in the current period were due to retirement of assets in the normal course of business. The loss on retirement of fixed assets in the current period included $12.3 million of losses related to Former Six Flags operations during the six months ended June 29, 2025 and $7.0 million of losses related to sunset website and mobile app assets at Former Six Flags. In connection with the preparation of the financial statements for the third quarter of 2025, management tested the Former Six Flags and Schlitterbahn reporting units, as well as the Six Flags trade name and Schlitterbahn trade name, for impairment due to a decline in estimated future cash flows as a result of revenue and earnings not meeting expectations through the more seasonally significant third quarter and due to a more significant, sustained decline in the Company's share price through the third quarter when compared to industry peers. In connection with the preparation of the financial statements for the third quarter, which includes the peak summer months of July and August and by itself can account for nearly half of full year attendance and over half of full year earnings, management had greater clarity regarding performance trends and full year results. Management concluded the estimated fair value of these trade names and certain reporting units no longer exceeded their carrying values resulting in a cumulative $1.52 billion impairment recorded during the third quarter of 2025 (see Note 5 to the accompanying consolidated financial statements). During the third quarter of 2024, management tested the Schlitterbahn reporting unit for impairment due to a decline in estimated future cash flows as a result of changes in planned capital allocations across the Company portfolio following the Mergers. Management concluded the estimated fair value of the Schlitterbahn reporting unit no longer exceeded its carrying value resulting in a $42.5 million impairment recorded during the third quarter of 2024. After the items above, operating loss for 2025 totaled $1.38 billion compared with operating income of $310.5 million for 2024. The amount for 2025 included $162.9 million of operating loss attributable to the Former Six Flags operations during the six months ended June 29, 2025. Net interest expense for 2025 increased $125.2 million as a result of $93.9 million of interest incurred during the six months ended June 29, 2025 on debt acquired in the Mergers, interest accretion related to the Six Flags Over Georgia call option liability (see Note 7 to the accompanying consolidated financial statements), and additional revolver borrowings in 2025. The loss on early debt extinguishment of $8.0 million in the prior period was attributable to the full redemption of the 2025 senior notes, which were refinanced with a $1.0 billion senior secured term loan facility. Other (income) expense, net primarily represented the remeasurement of U.S. dollar denominated notes to an entity's functional currency. For 2025, a benefit for income taxes of $164.0 million was recorded compared with a provision for income taxes of $240.8 million for 2024. The decrease in provision for income taxes was primarily attributable to discrete non-cash provision to return adjustments related to the Merger-related windup of the Former Cedar Fair partnership, and the impact of impairment charges, the effects of non-controlling interest distributions, accretion on the Six Flags Over Georgia call option liability, and non-deductible executive compensation which was partially offset by lower pre-tax book income relative to the comparable period. After the items above and income attributable to non-controlling interests, net loss attributable to Six Flags Entertainment Corporation for 2025 totaled $1.60 billion, or $15.89 per diluted share of common stock. The net loss included $259.4 million of net loss related to the Former Six Flags operations during the six months ended June 29, 2025. Net income attributable to Six Flags Entertainment Corporation for 2024 totaled $231.2 million, or $3.22 per diluted share of common stock and limited partner unit. Net income margin primarily decreased as a result of the cumulative $1.52 billion impairment recorded during the third quarter of 2025. 28 Table of Contents Modified EBITDA and Adjusted EBITDA 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) income attributable to non-controlling interests. Both measures have been included to disclose the effect of non-controlling interests. Prior to the Mergers, Former Cedar Fair did not have net income attributable to non-controlling interests. Modified EBITDA and Adjusted EBITDA are not measurements of operating performance computed in accordance with generally accepted accounting principles ("GAAP") and should not be considered as a substitute for operating income, net income or cash flows from operating activities computed in accordance with GAAP. 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. These measures are provided as supplemental measures of the Company's operating results and may not be comparable to similarly titled measures of other companies. The table below sets forth a reconciliation of Modified EBITDA and Adjusted EBITDA to net (loss) income for the years ended December 31, 2025 and December 31, 2024. The results for the year ended December 31, 2024 include only Cedar Fair's results before giving effect to the Mergers through June 30, 2024 and include Combined Company results from July 1, 2024 through December 31, 2024. Years Ended December 31, (In thousands) 2025 2024 Net loss $ (1,549,466) $ (206,665) Interest expense, net 359,958  234,770  (Benefit) provision for taxes (163,980) 240,843  Depreciation and amortization 486,383  318,113  EBITDA (867,105) 587,061  Loss on early debt extinguishment —  7,974  Non-cash foreign currency (gain) loss (22,583) 30,557  Non-cash equity compensation expense 64,157  63,809  Loss on retirement of fixed assets, net 40,670  18,064  Loss on impairment of goodwill and other intangibles 1,518,099  42,462  Loss on other assets 791  —  Costs related to the Mergers (1) 48,911  118,336  Severance (2) 44,564  1,397  Self-insurance adjustment (3) —  14,865  Other (4) 14,138  15,265  Modified EBITDA 841,642  899,790  Net income attributable to non-controlling interests 49,632  24,499  Adjusted EBITDA $ 792,010  $ 875,291  Modified EBITDA margin (5) 27.1  % 33.2  % (1)    Consists of third-party legal and consulting transaction costs, as well as integration costs related to the Mergers. Integration costs include 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 (see Note 2 to the accompanying consolidated financial statements). These costs are added back to net (loss) income 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. During 2025, certain employees, including certain executive level employees, were terminated as part of recent post-merger productivity and efficiency efforts. (3)    During the third quarter of 2024, an actuarial analysis of Former Cedar Fair's self-insurance reserves resulted in a change in estimate that increased the incurred but not reported ("IBNR") reserves related to these self-insurance reserves by $14.9 million. The increase was driven by an observed pattern of increasing litigation and settlement costs (see Note 1 to the accompanying consolidated financial statements). (4)    Consists of certain costs as defined in the Company's credit agreement. These costs are added back to net (loss) income to calculate Modified EBITDA and Adjusted EBITDA and include certain legal and consulting expenses; enacted cost savings initiatives related to overhead and administrative costs incurred by Former Six Flags, specifically for insurance premiums, 29 Table of Contents legal costs and information technology costs; certain costs at a combination amusement and water park located in Bowie, Maryland since its closure; repairs for unusual weather events; Mexican VAT taxes on intercompany activity; cost of goods sold recorded to align inventory standards following the Mergers; administrative payments related to the Partnership Parks; and contract termination costs. This balance also includes unrealized gains and losses on pension assets and short-term investments. (5)    Modified EBITDA margin (Modified EBITDA divided by net revenues) is not a measurement computed in accordance with GAAP and may not be comparable to similarly titled measures of other companies. Modified EBITDA margin is provided because management believes the measure provides a meaningful metric of operating profitability. Modified EBITDA margin has been disclosed as opposed to Adjusted EBITDA margin because management believes Modified EBITDA margin more accurately reflects the park-level operations of the Company as it does not give effect to distributions to non-controlling interests. For 2025, Adjusted EBITDA decreased $83.3 million and Modified EBITDA margin decreased 610 bps compared with 2024. The decreases in Adjusted EBITDA and Modified EBITDA margin were entirely due to lower revenues driven by lower attendance, which were somewhat offset by a reduction in expense, particularly lower labor and advertising costs. Liquidity and Capital Resources The Company's principal sources of liquidity include cash from operating activities, funding from long-term debt obligations and existing cash on hand. Due to the seasonality of the business, pre-opening operations are funded with revolving credit borrowings, which are reduced with positive cash flow during the seasonal operating period. Primary uses of liquidity include operating expenses, capital expenditures, interest payments, and income tax obligations. With the Company's revolving credit facility and cash on hand, the Company has sufficient liquidity to satisfy existing cash obligations at least through one year of the filing date of this Form 10-K. The Company's capital allocation priorities include reducing outstanding debt and reinvesting in the business. As such, the Company has not declared a dividend and has no immediate plans to do so. Capital expenditures for the Company are expected to total between $400 million and $425 million in 2026. Cash interest payments for the Company are expected to range from $320 million to $330 million in 2026. Cash payments for income taxes for the Company, excluding refunds, are expected to range from $25 million to $30 million in 2026. As of December 31, 2025, deferred revenue totaled $310.8 million, including non-current deferred revenue. This represented an increase of $2.5 million compared with total deferred revenue as of December 31, 2024. The increase in total deferred revenue was largely attributable to higher advanced single day sales and increased deposits on group events and catering. Cash Flows The following table presents key cash flow information for the years ended December 31, 2025 and December 31, 2024: Years Ended December 31, 2025 2024 (Amounts in thousands) Net cash from operating activities $ 327,469  $ 373,412  Net cash for investing activities (479,667) (472,616) Net cash from financing activities 155,405  117,973  Effect of exchange rate on cash and cash equivalents 4,753  (1,083) Net increase in cash and cash equivalents $ 7,960  $ 17,686  Net cash from operating activities in 2025 totaled $327.5 million, a decrease of $45.9 million compared with 2024. The decrease was primarily due to lower earnings and higher interest costs somewhat offset by less cash payments for income taxes and merger-related costs. Net cash for investing activities in 2025 totaled $479.7 million, an increase of $7.1 million compared with 2024. The increase was due to the inclusion of capital expenditures for Former Six Flags parks during the first six months of 2025 and incremental capital expenditures in the current period offset by net cash consideration paid for the Mergers in the prior period. Net cash from financing activities in 2025 totaled $155.4 million, an increase of $37.4 million compared with 2024. The increase was primarily attributable to higher prior year payments of debt issuance costs and prior year Cedar Fair partnership distributions somewhat offset by higher payments for tax withholding for equity compensation. Net debt borrowings in 2025 largely equaled net debt borrowings in 2024. For a discussion regarding 2023 cash flows, including comparisons of 2024 cash flows to 2023 cash flows, see "Management's Discussion and Analysis of Financial Condition and Results of Operations" within the Company's Annual Report on Form 10-K for the year ended December 31, 2024 filed with the SEC on March 3, 2025. 30 Table of Contents Contractual Obligations As of December 31, 2025, the Company's primary contractual obligations consisted of outstanding long-term debt agreements and related interest, certain obligations pertaining to the Partnership Parks (including the acquisition of all of the outstanding limited partnership interests in Six Flags Over Georgia and White Water Atlanta in January 2027; see Note 7 to the accompanying consolidated financial statements), and various commitments under lease agreements (see Note 11 to the accompanying consolidated financial statements). The Company has also committed to certain capital expenditures of approximately $90 million, most of which will be paid in 2026, and license commitments of approximately $10 million per year through 2030 and $6.7 million per year from 2031 through 2034. Before reduction for debt issuance costs, original issue discount and acquisition fair value layers, the Company's long-term debt agreements as of December 31, 2025 consisted of the following: •$1,481 million of senior secured term debt, maturing in May 2031 under the 2024 Credit Agreement, as amended. Amortization payments of $15 million per year, paid in equal quarterly installments, are required to be made on the term debt. The term debt bears interest at a rate equal to Term Secured Overnight Financing Rate ("SOFR") plus a margin of 200 bps per annum or base rate plus a margin of 100 bps per annum. There was $15.0 million of current maturities outstanding and payable within the next twelve months as of December 31, 2025 related to the senior secured term debt facility. •$500 million of 5.375% senior unsecured notes, previously set to mature in April 2027. Interest was payable under the 2027 senior notes semi-annually in April and October, and the notes were redeemed in full on February 5, 2026 with the proceeds of $1.0 billion of 8.625% senior unsecured notes due 2032 that were issued on January 14, 2026 (the "2032 senior notes", see Note 14 to the accompanying consolidated financial statements). •$300 million of 6.500% senior unsecured notes, maturing in October 2028. Interest is payable under the 2028 senior notes semi-annually in April and October. •$500 million of 5.250% senior unsecured notes, maturing in July 2029. Interest is payable under the 2029 senior notes semi-annually in January and July. •$500 million of 5.500% senior unsecured notes, previously set to mature in April 2027. Interest was payable under the 2027 Six Notes semi-annually in April and October, and the notes were redeemed in full on February 5, 2026 with the proceeds of the 2032 senior notes (see Note 14 to the accompanying consolidated financial statements). •$800 million of 7.250% senior unsecured notes, maturing in May 2031. Interest is payable under the 2031 Six Notes semi-annually in May and November. •$850 million of 6.625% senior secured notes, maturing in May 2032. Interest is payable under the 2032 Six Notes semi-annually in May and November. •$272 million of borrowings under the $850 million senior secured revolving credit facility under the 2024 Credit Agreement, as amended. The revolving credit facility bears interest at Term SOFR or Term Canadian Overnight Repo Rate Average plus a margin of 200 bps per annum, or base rate or Canadian prime rate plus a margin of 100 bps per annum; matures on July 1, 2029, following the amendment to the 2024 Credit Agreement and subject to a springing maturity date on the date that is 91 days prior to the final maturity of certain indebtedness in an aggregate outstanding principal amount greater than $200 million on such date; and requires a commitment fee of 50 bps per annum on the unused portion of the revolving credit facility, which is subject to decrease to 37.5 bps upon achievement of a 3.5x Net First Lien Leverage Ratio (as defined in the 2024 Credit Agreement, as amended). The 2024 Credit Agreement also provides for the issuance of documentary and standby letters of credit. After letters of credit of $45.8 million as of December 31, 2025, the Company had $532.2 million of availability under the revolving credit facility. Letters of credit are primarily in place to backstop insurance arrangements. On January 14, 2026, the Company issued $1.0 billion of the 2032 senior notes. The proceeds from the 2032 senior notes, together with cash on hand, were used to redeem the 2027 senior notes and the 2027 Six Notes in full on February 5, 2026, along with accrued and unpaid interest. Interest is payable under the 2032 senior notes semi-annually in January and July of each year with the principal due in full on January 15, 2032. See Note 14 to the accompanying consolidated financial statements. With respect to the revolving credit facility only, the 2024 Credit Agreement, as amended, includes a maximum Net First Lien Leverage Ratio (as defined in the 2024 Credit Agreement) financial maintenance covenant, which is required to be tested as of the last day of each quarter except for the quarter in which the consummation of the Mergers occurred. The maximum Net First Lien Leverage Ratio is 5.0x beginning with the test period ending on or about December 31, 2025, with step-downs of 25 bps after every four consecutive quarters, culminating at 4.5x beginning with the test period ending on or about December 31, 2027. The 2024 Credit Agreement, as amended, and fixed rate note agreements include restricted payment provisions, which could limit the Company's ability to pay dividends. Under the 2024 Credit Agreement, as amended, if the pro forma Net Secured Leverage Ratio (as defined in the 2024 Credit Agreement) is less than or equal to 3.00x, the Company can make unlimited 31 Table of Contents restricted payments so long as no event of default has occurred and is continuing. If the pro forma Net Total Leverage Ratio (as defined in the 2024 Credit Agreement) is less than or equal to 5.25x, the Company can make restricted payments up to the then-available Cumulative Credit (as defined in the 2024 Credit Agreement), so long as no event of default has occurred and is continuing. Irrespective of any leverage calculations, the Company can make restricted payments not to exceed the greater of 7.0% of Market Capitalization (as defined in the 2024 Credit Agreement) and $200 million annually. Pursuant to the terms of the indentures governing the Company's senior notes, if the pro forma Total Indebtedness to Consolidated Cash Flow Ratio (as defined in the indentures governing the 2028 senior notes, 2029 senior notes and 2031 Six Notes) or the pro forma Net Total Leverage Ratio (as defined in the 2032 senior notes and the 2032 Six Notes) is less than or equal to 5.50x, the Company can make restricted payments up to its restricted payment pool so long as no default or event of default has occurred and is continuing or would occur as a consequence thereof. The Company's pro forma Total Indebtedness to Consolidated Cash Flow Ratio and pro forma Net Total Leverage Ratio were greater than 5.50x as of December 31, 2025. On November 9, 2023, Cedar Fair entered into supplemental indentures related to the 2025 senior notes, 2027 senior notes, 2028 senior notes and 2029 senior notes (the "Amendments") following receipt of requisite consents from the holders of the notes. The Amendments enabled Cedar Fair to select November 2, 2023, the date the Merger Agreement with Former Six Flags was entered into, as the testing date for purposes of calculating, with respect to the Mergers and related transactions, any and all ratio tests under those notes, each of which was satisfied when tested on November 2, 2023. To become operative, the Amendments required a payment, which was made upon the consummation of the Mergers. The payment related to the 2025 senior notes was still required despite the redemption of those notes in May 2024. Financial and Non-Financial Disclosure About Issuers and Guarantors of Registered Senior Notes Three tranches of fixed rate senior notes outstanding as of December 31, 2025 were registered under the Securities Act of 1933: the 2027, 2028 and 2029 senior notes, or the "registered senior notes". The 2027 senior notes were redeemed in full on February 5, 2026 (see Note 14 to the accompanying consolidated financial statements). The Company, Canada's Wonderland Company ("Cedar Canada"), Magnum Management Corporation ("Magnum"), and Millennium Operations LLC (“Millennium”) are the co-issuers of the registered senior notes. Substantially concurrently with the closing and in connection with the Mergers, the Company entered into supplemental indentures to assume all of Former Cedar Fair's obligations under the indentures governing the registered senior notes. Pursuant to the supplemental indentures, each of the Former Six Flags subsidiary guarantors under the 2024 Credit Agreement agreed to fully and unconditionally guarantee the registered senior notes. As a result, the registered senior notes are irrevocably and unconditionally guaranteed, on a joint and several basis, by each wholly owned subsidiary of the Company (other than the co-issuers) that guarantees the credit facilities under the 2024 Credit Agreement, as amended. A full listing of the issuers and guarantors of the registered senior notes can be found within Exhibit 22. The registered senior notes each rank equally in right of payment with all of each issuer’s existing and future senior unsecured debt. However, the registered senior notes rank effectively junior to any secured debt to the extent of the value of the assets securing such debt, including under the 2024 Credit Agreement and the 2032 Six Notes. In the event that the co-issuers (except for the Company) or any subsidiary guarantor is released from its obligations under the 2024 Credit Agreement, such entity will also be released from its obligations under the 2029 senior notes and from its guarantee under the 2028 senior notes. In addition, the co-issuers (except for the Company) or any subsidiary guarantor can be released from its obligations under the registered senior notes under the following circumstances, assuming the associated transactions are in compliance with the applicable provisions of the indentures governing the registered senior notes: i) in the case of co-issuers (other than the Company), any direct or indirect sale, conveyance or other disposition of the capital stock of such entity following which the entity ceases to be a direct or indirect subsidiary of the Company or a sale or disposition of all or substantially all of the assets of such entity made in accordance with the applicable indenture; ii) if such entity is dissolved or liquidated; iii) if an entity is designated as an Unrestricted Subsidiary (as defined in each indenture); iv) in the case of the 2029 senior notes, upon transfer of such entity in a qualifying transaction if following such transfer the entity ceases to be a direct or indirect Restricted Subsidiary (as defined in each indenture) of the Company or is a Restricted Subsidiary that is not a guarantor under any credit facility; or v) in the case of the subsidiary guarantors, upon a discharge of the indenture or upon any legal defeasance or covenant defeasance of the indenture. The obligations of each guarantor are limited to the extent necessary to prevent such guarantee from constituting a fraudulent conveyance or fraudulent transfer under applicable law. This provision may not, however, protect a guarantee from being voided under fraudulent transfer law, or may reduce the applicable guarantor’s obligation to an amount that effectively makes its guarantee worthless. If a guarantee were rendered voidable, it could be subordinated by a court to all other indebtedness of the guarantor, and depending on the amount of such indebtedness, could reduce the guarantee to zero. Each guarantor that makes a payment or distribution under a guarantee is entitled to a pro rata contribution from each other guarantor based on the respective net assets of the guarantors. The following tables provide summarized financial information for each of the co-issuers and guarantors of the registered senior notes (the "Obligor Group") as of December 31, 2025 and December 31, 2024. Each entity that was a co-issuer of the registered senior notes is presented separately. The subsidiaries that guaranteed the registered senior notes are presented on a combined basis with intercompany balances and transactions between entities in such guarantor subsidiary group eliminated. 32 Table of Contents Intercompany balances and transactions between the co-issuers and guarantor subsidiaries were not eliminated. Certain subsidiaries did not guarantee the credit facilities or senior notes (the "non-guarantor" subsidiaries). The summarized financial information excludes results of the non-guarantor subsidiaries. The Obligor Group's amounts due from, amounts due to, and transactions with the non-guarantor subsidiaries have not been eliminated and included intercompany receivables from non-guarantors of $188.3 million and $123.6 million as of December 31, 2025 and December 31, 2024, respectively.

The objective of the Company's financial risk management is to reduce the potential negative impact of interest rate and foreign currency exchange rate fluctuations to acceptable levels. Market risk sensitive instruments are not acquired for trading purposes. Interest rate risk is typically managed using a combination of fixed-rate and variable-rate long-term debt. Translation exposures with regard to Canadian and Mexican operations are not hedged. As of December 31, 2025, variable rate debt included $1,481 million of senior secured term loan facility borrowings and borrowings under an $850 million revolving credit facility under the 2024 Credit Agreement, as amended. Assuming the outstanding senior secured term loan facility borrowings and the daily average balance over the past twelve months on revolving credit borrowings of approximately $387.1 million, a hypothetical 100 bps increase in 30-day SOFR on the variable-rate debt would lead to an increase of approximately $18.7 million in cash interest costs over the next twelve months. A uniform 10% strengthening of the U.S. dollar relative to the Canadian dollar and Mexican peso would have resulted in a $1.1 million decrease in operating loss contributed to the Company's results for the year ended December 31, 2025. 33 Table of Contents Forward Looking Statements Some of the statements contained in this report (including the "Management's Discussion and Analysis of Financial Condition and Results of Operations" section) that are not historical in nature are forward-looking statements within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including statements as to management's expectations, beliefs, goals and strategies regarding the future.
