This Quarterly Report on Form 10-Q (this "Quarterly Report") and the documents incorporated herein by reference contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements include all statements that are not historical facts and can be identified by words such as "anticipates," "intends," "plans," "seeks," "believes," "estimates," "expects," "may," "should," "could" and variations of such words or similar expressions. These forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties, assumptions and other factors, some of which are beyond our control, which could cause actual results to differ materially from those expressed or implied by such forward-looking statements. These factors include (i) global coronavirus (“COVID-19”) pandemic-related business disruptions and economic uncertainty (ii) the adequacy of our cash flows from operations, available cash and available amounts under our credit facilities to meet our liquidity needs, (iii) our expectations regarding the timing, costs, benefits and results of our strategic plan, (iv) impact of macro-economic conditions, including inflation on consumer spending, (iv) our ability to implement our capital plans in a timely and cost effective manner, and our expectations regarding the anticipated costs, benefits and results of such capital plans, (vi) the extent to which having parks in diverse geographical locations protects our consolidated results against the effects of adverse weather and other events, (vii) our ongoing compliance with laws and regulations, and the effect of, and cost and timing of compliance with, newly enacted laws and regulations, (viii) our ability to obtain additional financing and the increased cost of capital due to rising interest rates, (x) our expectations regarding the effect of certain accounting pronouncements, (xi) our expectations regarding the cost or outcome of any litigation or other disputes, (xii) our annual income tax liability and the availability and effect of net operating loss carryforwards and other tax benefits, and (xii) our expectations regarding uncertain tax positions.

Forward-looking statements are based on our current expectations and assumptions regarding our business, the economy and other future conditions. Because forward-looking statements relate to the future, they are, by their nature, subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict. Additional risks and uncertainties that could cause actual results to differ materially from those described in such forward-looking statements include, among others, the following:

•factors impacting our ability to consummate the transactions (collectively the “Merger”) contemplated by that certain Agreement and Plan of Merger, dated November 2, 2023, by and among Six Flags Entertainment Corporation, (“Holdings”), Cedar Fair, L.P., (“Cedar Fair”), CopperSteel HoldCo, Inc., and CopperSteel Merger Sub, LLC;

•the risk that the proposed Merger disrupts current plans and operations of the Company and the effect of the announcement or pendency of the Merger on the business relationships, operating results and business generally of the Company;

•the occurrence of any event, change or other circumstance that could give rise to the termination of the Merger Agreement;

•factors impacting attendance, such as local conditions, contagious diseases, including COVID-19 and Monkey Pox, or the perceived threat of contagious diseases, events, disturbances and terrorist activities;

•regulations and guidance of federal, state and local governments and health officials regarding the response to COVID-19 and Monkey Pox, including, with respect to business operations, safety protocols and public gatherings (such as voluntary and, in some cases, mandatory, quarantines, as well as shut downs and other restrictions on travel and commercial, social and other activities);

•economic impact of political instability and conflicts globally, such as the war in Ukraine and the Middle East;

•recall of food, toys and other retail products sold at our parks;

•accidents or incidents involving the safety of guests and employees, or contagious disease outbreaks at our parks or other parks in our industry, and negative publicity about us or our industry;

•availability of commercially reasonable insurance policies at reasonable rates;

•inability to achieve desired improvements and financial performance targets;

•adverse weather conditions, such as excess heat or cold, rain and storms;

•general financial and credit market conditions, including our ability to access credit or raise capital;

•macro-economic conditions (including supply chain issues and the impact of inflation on customer spending patterns);

•our ability to successfully implement our strategy;

•changes in public and consumer tastes;

•construction delays in capital improvements or ride downtime;

•competition with other theme parks, water parks and entertainment alternatives;

•dependence on a seasonal workforce;

•unionization activities and labor disputes;

•laws and regulations affecting labor and employee benefit costs, including increases in state and federally mandated minimum wages, healthcare reform and potential wage and hour claims;

•availability of labor;

•environmental laws and regulations;

•laws and regulations affecting corporate taxation;

•pending, threatened or future legal proceedings and the significant expenses associated with litigation;

•cyber security risks; and

Table of Contents

•other factors or uncertainties described in "Item 1A. Risk Factors" set forth in our Annual Report on Form 10-K for the year ended January 1, 2023 (the "2022 Annual Report"), and in this Quarterly Report.

While we believe that the expectations reflected in such forward-looking statements are reasonable, we make no assurance that such expectations will be realized and actual results could vary materially. Factors or events that could cause our actual results to differ may emerge from time to time, and it is not possible for us to predict all of them.

1. General — Basis of Presentation

We own and operate regional theme parks and water parks. We are the largest regional theme park operator in the world, and we are the largest operator of water parks in North America based on the number of parks we operate. Of the 27 parks we own or operate, 24 parks are located in the United States, two are located in Mexico, and one is located in Montreal, Canada.

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed, or omitted, pursuant to the rules and regulations of the SEC.

Our current fiscal year will end on December 31, 2023. This Quarterly Report covers the period January 2, 2023 – October 1, 2023 (“the nine months ended October 1, 2023”) and the period July 3, 2023 – October 1, 2023 (“the three months ended October 1, 2023”). The comparison period in the prior year covers the dates January 3, 2022 – October 2, 2022 (“the nine months ended October 2, 2022”) and the period July 4, 2022 – October 2, 2022 (“the three months ended October 2, 2022”).

The 2022 Annual Report includes additional information about us, our operations and our financial position, and should be referred to in conjunction with this Quarterly Report. The information furnished in this Quarterly Report reflects all normal and recurring adjustments that are, in the opinion of management, necessary to present a fair statement of the results for the periods presented.

Results of operations for the three and nine months ended October 1, 2023, are not indicative of the results expected for the full year. Our operations are highly seasonal, with approximately 70% - 75% of park attendance and revenues in a typical year occurring in the second and third calendar quarters of each year, with the most significant period falling between Memorial Day and Labor Day.

Certain previously reported amounts have been reclassified to conform to the current year presentation. During 2023, we reclassified the net pension-related expense (benefit) to other (income) expense, net, in our consolidated statements of operations. We have separated “(Gain) loss on disposal of assets” from “Other” on the condensed consolidated statement of cash flows.

Revision of Previously Issued Financial Statements

We have assessed the error and concluded that it was not material to any prior periods. However, the aggregate amount of the error would have been material to our condensed consolidated financial statements in the current period. Therefore, we have revised our previously issued financial information. Prior periods not presented herein will be revised, as applicable, in future filings. Refer to Note 10 - Revision to Previously Reported Financial Information for additional information.

a. Consolidated U.S. GAAP Presentation

Our accounting policies reflect industry practices and conform to U.S. GAAP.

The unaudited condensed consolidated financial statements include our accounts and the accounts of our wholly owned subsidiaries. We also consolidate the partnerships that own Six Flags Over Texas ("SFOT") and Six Flags Over Georgia (including Six Flags White Water Atlanta) ("SFOG", and together with SFOT, the "Partnership Parks") in our unaudited condensed consolidated financial statements, as we have determined that we have the power to direct the activities of the Partnership Parks that most significantly impact their economic performance and we have the obligation to absorb losses and receive benefits from the Partnership Parks that can be potentially significant to these entities. The equity interests owned by non-affiliated parties in the Partnership Parks are reflected in the accompanying unaudited condensed consolidated balance sheets as redeemable noncontrolling interests.

b. Income Taxes

We recorded a valuation allowance of $99.4 million, $96.0 million and $109.0 million as of October 1, 2023, January 1, 2023, and October 2, 2022, respectively, due to uncertainties related to our ability to use some of our deferred tax assets, primarily consisting of certain state net operating loss and other tax carryforwards, before they expire. The valuation allowance is based on our estimates of

Table of Contents

taxable income by jurisdiction in which we operate and the period over which our deferred tax assets are recoverable. Our projected taxable income over the foreseeable future indicates we will be able to use all of our federal net operating loss carryforwards before they expire.

We classify interest and penalties attributable to income taxes as part of income tax expense. As of October 1, 2023, January 1, 2023, and October 2, 2022, we had no recorded amounts for accrued interest or penalties.

c. Goodwill and Intangibles

As of October 1, 2023, the fair value of our single reporting unit exceeded our carrying amount. We have one reporting unit at the same level for which Holdings common stock is traded and we believe our market capitalization is the best indicator of our reporting unit’s fair value. As of October 1, 2023, we did not identify any triggering events that would require a full quantitative analysis to be performed.

d. Long-Lived Assets

We review long-lived assets, including finite-lived intangible assets subject to amortization, for impairment upon the occurrence of events or changes in circumstances that would indicate that the carrying value of the asset or group of assets may not be recoverable, “triggering event(s)”. Recoverability of assets to be held and used is measured by comparing the carrying amount of the asset or group of assets to the projected future net cash flows expected to be generated by the asset or group of assets. If such assets are not determined to be fully recoverable, any impairment to be recognized is measured by the amount by which the carrying amount of the asset or group of assets exceeds its respective estimated fair value. Assets held-for-sale are reported at the lower of the carrying amount or fair value less costs to sell. As of October 1, 2023, we did not identify any triggering events that would require a quantitative analysis.

e. Earnings Per Common Share

Earnings per common share for the three and nine months ended October 1, 2023 and October 2, 2022, was calculated as follows:


	Three Months Ended				Nine Months Ended
(Amounts in thousands, except per share data)	October 1, 2023		October 2, 2022		October 1, 2023		October 2, 2022
Net income attributable to Six Flags Entertainment Corporation	$	110,700	$	113,507	$	61,395	$	91,279

Weighted-average common shares outstanding - basic:	83,510		83,094		83,365		84,760
Effect of dilutive stock options and restricted stock units	270		13		371		159
Weighted-average common shares outstanding - diluted:	83,780		83,107		83,736		84,919

Earnings per share - basic:	$	1.33	$	1.37	$	0.74	$	1.08
Earnings per share - diluted:	$	1.32	$	1.37	$	0.73	$	1.07

The computation of diluted earnings per share excluded the effect of 1,406,000 and 2,509,000 antidilutive stock options and restricted stock units for the three months ended October 1, 2023, and October 2, 2022, respectively, and excluded the effect of 1,474,000 and 2,979,000 antidilutive stock options and restricted stock units for the nine months ended October 1, 2023, and October 2, 2022, respectively.

f. Stock Benefit Plans

Pursuant to the Six Flags Entertainment Corporation Long-Term Incentive Plan (the "Long-Term Incentive Plan"), we may grant stock options, stock appreciation rights, restricted stock, restricted stock units, unrestricted stock, deferred stock units, performance stock units, performance and cash-settled awards and dividend equivalent rights ("DERs") to select employees, officers, directors and consultants.

Periodically, we grant performance stock units to key employees. These awards vest based on attainment of specific performance targets most often related to Adjusted EBITDA or revenue over a defined period. As of October 1, 2023, we have not determined that it is probable that we will achieve any of the performance targets associated with our outstanding performance units, and we have therefore not recognized any expense for these awards.

Table of Contents

During the three and nine months ended October 1, 2023 and October 2, 2022, stock-based compensation expense consisted of the following:


	Three Months Ended				Nine Months Ended
(Amounts in thousands)	October 1, 2023		October 2, 2022		October 1, 2023		October 2, 2022
Long-term incentive plan	$	3,495	$	4,004	$	8,902	$	13,341
Employee stock purchase plan	30		(6)		116		63
Total stock-based compensation	$	3,525	$	3,998	$	9,018	$	13,404

g. Accounts Receivable, Net

Accounts receivable are reported at net realizable value and consist primarily of amounts due from guests for the sale of group outings and multi-use admission products that allow for payment plans, such as season passes, annual passes, memberships and our Six Flags Plus pass. We are not exposed to a significant concentration of credit risk; however, based on the age of receivables, our historical experience and other factors and assumptions we believe to be customary and reasonable, we record an allowance for doubtful accounts. As of October 1, 2023, January 1, 2023, and October 2, 2022, we have recorded an allowance for doubtful accounts of $10.1 million, $4.1 million, and $7.6 million, respectively, which is primarily comprised of estimated payment defaults under our Six Flags Plus pass and other multi-use admission products that allow for payment plans. To the extent that payments for products for which an allowance for doubtful accounts is established have not been recognized in revenue, the allowance recorded is offset with a corresponding reduction in deferred revenue.

h. Recently Adopted Accounting Pronouncements

In March 2020, FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“Update 2020-04”), which provides optional expedients and exceptions for applying U.S. GAAP principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in Update 2020-04 apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected optional expedients for and that are retained through the end of the hedging relationship. The provisions in Update 2020-04 are effective upon issuance and can be applied prospectively through December 31, 2022. As of October 1, 2023, we no longer have any debt instruments that contain LIBOR as a reference rate. Our adoption of Update 2020-04 did not have any effect on our condensed consolidated financial statements.

2. Revenue

Revenues are recognized when control of the promised goods or services is transferred to our customers in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Sales and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense.

The following tables present our revenues disaggregated by contract duration for the three and nine month periods ended October 1, 2023 and October 2, 2022, respectively. Long-term and short-term contracts consist of our contracts with customers with terms greater than one year and less than or equal to one year, respectively.

Long-term Contracts

As of January 1, 2023, $33.5 million of unearned revenue associated with outstanding long-term contracts was reported in "Deferred revenue," of which $30.8 million and $51.6 million was recognized as revenue for long-term contracts during the three and nine months ended October 1, 2023, respectively. As of October 1, 2023, the total unearned amount of revenue for remaining long-term contract performance obligations was $71.6 million. As of January 1, 2022, $58.7 million of unearned revenue associated with outstanding long-term contracts was reported in "Deferred revenue," of which $24.6 million and $49.4 million was recognized as revenue for long-term contracts during the three and nine months ended October 2, 2022, respectively. As of October 2, 2022, the total unearned amount of revenue for remaining long-term contract performance obligations was $21.4 million.

As of October 1, 2023, we expect to recognize estimated revenue for partially or wholly unsatisfied performance obligations on long-term contracts of approximately $13.9 million in the remainder of 2023, $73.6 million in 2024, $9.2 million in 2025, $7.1 million in 2026, and $12.8 million in 2027 and thereafter.

3. Long-Term Indebtedness

Credit Facility

As of October 1, 2023, our credit facility consisted of a $500.0 million revolving credit facility (the “Revolving Credit Facility”) and a $479.0 million Tranche B Term Loan facility (the “Term Loan B”) pursuant to the amended and restated credit facility that we entered into in May 2023 (the “Credit Facility”).

Concurrently with the closing of the $800.0 million in aggregate principal amount of 7.25% senior unsecured notes due 2031 (“2031 Notes”), the Company amended its existing senior secured credit facility to, among other things, (i) establish a $500.0 million replacement revolving credit facility maturing in May 2028, subject to springing maturity conditions, which was previously scheduled to expire in April 2024 (ii) maintain the same interest rate margins on borrowings under the replacement revolving credit facility as were previously in effect, while reducing the fee on unused revolving commitments to 0.5%, stepping down to 0.375% upon achieving a senior

Table of Contents

secured leverage ratio of less than 1.25:1.00, (iii) replace LIBOR as the interest rate benchmark for borrowings under the senior secured credit facility with Term SOFR, plus a 0.10% Term SOFR Adjustment, (iv) modify the maximum senior secured leverage ratio that the Company must maintain to 4.50:1.00 for the four fiscal-quarter periods ending on or about December 31, 2022, March 31, 2023, and June 30, 2023, 4.25:1.00 for the four fiscal-quarter period ending on or about September 30, 2023, and each four fiscal-quarter period thereafter through the four fiscal-quarter period ending on or about June 30, 2024, and 3.75:1.00 for the four fiscal-quarter period ending on or about September 30, 2024, and each four fiscal-quarter period thereafter, and (v) make certain other changes to the covenants and other terms of the senior secured credit facility. We incurred a $0.1 million loss on debt extinguishment related to the write-off of deferred financing costs related to the transaction.

As of October 1, 2023, our available borrowing capacity under our Revolving Credit Facility was $390.0 million after reducing the facility by $89.0 million borrowings outstanding and $21.0 million of outstanding letters of credit. As of January 1, 2023 and October 2, 2022, $100.0 million and $110.0 million, respectively, under the Revolving Credit Facility were outstanding (excluding amounts reserved for letters of credit in the amount of $21.0 million). Interest on the Revolving Credit Facility accrues at an annual rate of SOFR, plus a Term SOFR Adjustment of 0.10%, plus an applicable margin with an unused commitment fee based on our senior secured leverage ratio. As of October 1, 2023, the Revolving Credit Facility had an interest rate of 8.66%. As of October 1, 2023, the Revolving Credit Facility unused commitment fee was 0.500%. The Revolving Credit Facility matures in May 2028.

As of October 1, 2023, January 1, 2023 and October 2, 2022, $479.0 million was outstanding under the Term Loan B. Interest on the Term Loan B accrues at an annual rate of SOFR, plus a Term SOFR Adjustment of 0.10%, plus 1.75%. The Term Loan B consists of only floating rate debt. As of October 1, 2023, the applicable interest rate on the Term Loan B was 7.17%. The Term Loan B matures on April 17, 2026.

2024 Notes, 2025 Notes, 2027 Notes and 2031 Notes

In June 2016, Holdings issued $300.0 million of 4.875% senior unsecured notes due 2024 and, in April 2017, issued an additional $700.0 million of senior unsecured notes due 2024 (together, the “2024 Notes”). During March of 2020, we prepaid $50.5 million of the outstanding 2024 Notes principal, reducing the outstanding amount to $949.5 million. On April 26, 2023, we commenced a cash tender offer (the “Tender Offer”) for any and all outstanding 2024 Notes. The consideration offered for each $1,000 principal amount of the 2024 Notes was $1,000.50 (the “Purchase Price”), plus accrued and unpaid interest. On May 3, 2023, we repaid $892.6 million, or 94.0% of the aggregate principal amount of the 2024 Notes that were tendered to us. The remainder of the 2024 Notes is due in July 2024.

In April 2017, Holdings issued $500.0 million of 5.50% senior notes due 2027 (the "2027 Notes"). In April 2020, our subsidiary Six Flags Theme Parks (“SFTP”) issued $725.0 million of 7.00% senior secured notes due 2025 (the “2025 Notes”).

On July 1, 2022, Holdings prepaid $360.0 million of the 2025 Notes at a premium of 103.5%. The transaction reduced the outstanding amount of the 2025 Notes to $365.0 million. We incurred a $17.5 million loss on debt extinguishment containing $12.6 million for the premium paid above par and $4.9 million related to the write-off of deferred financing costs related to the transaction which was recognized during the nine months ended October 2, 2022.

Also, on May 3, 2023, the Company announced that $892.6 million, or 94.0% of the aggregate principal amount of the 2024 Notes were validly tendered pursuant to the Tender Offer. Net cash proceeds from the 2031 Notes, together with other available cash, including borrowings under our Revolving Credit Facility, were used to pay the Purchase Price, plus accrued and unpaid interest. We incurred a $13.9 million loss on debt extinguishment comprised of $1.0 million for the premium paid above par and $12.9 million of costs charged to expense on debt modification which were recognized during the nine months ended October 1, 2023.

As of October 1, 2023, $56.9 million of the 2024 Notes, $365.0 million of the 2025 Notes, $500.0 million of the 2027 Notes and $800.0 million of the 2031 Notes, were issued and outstanding. Interest payments of $1.4 million for the 2024 Notes are due semi-annually on January 31 and July 31 of each year. Following the repayment of $360 million of the 2025 Notes, interest payments of $12.7 million for the 2025 Notes are due semi-annually on January 1 and July 1 each year. Interest payments of $13.8 million for the 2027 Notes are due semi-annually on April 15 and October 15 of each year. For the 2031 Notes, an interest payment of $30.9 million is due November 15, 2023, and $29.0 million is due semi-annually on May 15 and November 15 of each year, thereafter.

5. Derivative Financial Instruments

We hold interest rate swap agreements that mitigate the risk of an increase in the effective interest rate on the Term Loan B. We enter into derivative contracts for risk management purposes only and do not utilize derivative instruments for trading or speculative purposes. As such, in conjunction with the repayment of a portion of the Term Loan B in April 2020, certain of our interest rate swap agreements were de-designated because the hedged interest was no longer probable to occur.

Derivative assets and derivative liabilities that have maturity dates equal to or less than twelve months from the balance sheet date are included in “Prepaid expenses and other current assets” and “Other accrued liabilities,” respectively. Derivative assets and derivative liabilities that have maturity dates greater than twelve months from the balance sheet date are included in “Deposits and other assets” and “Other long-term liabilities,” respectively.

On March 24, 2022, we terminated the August 2019 Swap Agreements for net cash proceeds of $7.4 million. The swap agreements were used as economic hedges against rising interest rates and had been designated as cash flow hedges prior to termination. We recorded the settlement in accumulated other comprehensive income in the amount of $7.7 million which will be amortized through September 2024, the maturity date of the Term Loan B.

6. Commitments and Contingencies

Partnership Parks

We have guaranteed the obligations of the general partners of those partnerships to (i) make minimum annual distributions (including rent) of approximately $85.6 million in 2023 (subject to cost of living adjustments) to the limited partners in the Partnership Parks (based on our ownership of units as of October 1, 2023, our share of the distribution will be approximately $38.1 million) and (ii) make minimum capital expenditures at each of the Partnership Parks during rolling five-year periods, based generally on 6.0% of the Partnership Parks’ revenues. Pursuant to the 2023 annual offer to purchase limited partnership units tendered by the unit holders (the "Partnership Park Put") in May 2023, we purchased 0.149 limited partnership units from the Texas partnership for $0.3 million. As we purchase additional units, we are entitled to a proportionate increase in our share of the minimum annual distributions.

The agreed price for units tendered in the Partnership Park Put is based on a valuation of each of the respective Partnership Parks (the "Specified Price") that is the greater of (a) a valuation for each of the respective Partnership Parks derived by multiplying such park’s weighted average four-year EBITDA (as defined in the agreements that govern the partnerships) by a specified multiple (8.0 in the case of SFOG and 8.5 in the case of SFOT) and (b) a valuation derived from the highest prices previously offered for the units of the Partnership Parks by certain entities. In light of the temporary suspension of operations of the parks due to the COVID-19 pandemic in March 2020, which would have caused the value of the Partnership Park units to decrease in 2021 and thereafter, we adjusted our

Table of Contents

annual offer to purchase these units to set a minimum price floor for all future purchases. Pursuant to the new minimum price floor, the Specified Price for the Partnership Parks, if determined as of October 1, 2023, is $409.7 million in the case of SFOG and $527.4 million in the case of SFOT. As of October 1, 2023, we owned approximately 31.5% and 54.1% of the Georgia limited partner interests and Texas limited partner interests, respectively. Our obligations with respect to SFOG and SFOT will continue until 2027 and 2028, respectively.

We incurred $20.6 million of capital expenditures at the Partnership Parks during the 2022 season and expect to incur approximately $28.0 million to $32.0 million of capital expenditures at these parks for the 2023 season, an amount in excess of the minimum required expenditure. Cash flows from operations at the Partnership Parks will be used to satisfy the annual distribution and capital expenditure requirements, before any funds are required from us. The Partnership Parks generated approximately $73.0 million of cash in 2022, after deduction of capital expenditures and excluding the impact of short-term intercompany advances from or payments to Holdings. As of October 1, 2023, January 1, 2023 and October 2, 2022, we had total loans receivable outstanding of $288.3 million from the partnerships that own the Partnership Parks. The loans were primarily used to fund the acquisition of Six Flags White Water Atlanta and to make capital improvements to the Partnership Parks and distributions to the limited partners in prior years.

Redeemable noncontrolling interests represent the non-affiliated parties’ interests in the Partnership Parks: SFOT, SFOG and Six Flags White Water Atlanta, which is owned by the partnership that owns SFOG. As of October 1, 2023, redeemable noncontrolling interests of the SFOG and SFOT partnerships were $292.1 million and $252.7 million, respectively.


(Amounts in thousands)	SFOT		SFOG		Total

Balance at October 1, 2023	$	252,658	$	292,106	$	544,764

The redemption value of the noncontrolling partnership units in SFOG and SFOT as of October 1, 2023, was approximately $280.2 million and $240.8 million, respectively.

Insurance

We maintain insurance of the types and in amounts that we believe are commercially reasonable and that are available to businesses in our industry.

The majority of our current insurance policies expire on December 31, 2023. We generally renegotiate our insurance policies on an annual basis. We cannot predict the level of the premiums that we may be required to pay for subsequent insurance coverage, the level of any self-insurance retention applicable thereto, the level of aggregate coverage available or the availability of coverage for specific risks.

Self-Insurance Reserves

Self-insurance reserves are recorded for the estimated amounts of guest and employee claims and expenses incurred each period that are not covered by insurance. Reserves are established for both identified claims and incurred but not reported (“IBNR”) claims. Such amounts are accrued for when claim amounts become probable and estimable. Reserves for identified claims are based upon the Company’s historical claims experience and third-party estimates of settlement costs. Reserves for IBNR claims are based upon our claims data history, actuarially determined loss development factors and certain other qualitative considerations. We maintain self-insurance reserves for healthcare, auto, general liability, and workers’ compensation claims.

Our self-insurance reserves are periodically reviewed for changes in facts and circumstances and adjustments are made as necessary. During the second quarter of 2023, an actuarial analysis of our general liability and worker’s compensation self-insurance reserves resulted in a change in estimate that increased our ultimate loss indications on both identified claims and IBNR claims. The determination to undertake such an actuarial analysis resulted from greater than previously estimated reserve adjustments on identified claims during the quarter as well as an observed pattern of increasing litigation and settlement costs. As a result of this actuarial analysis, we revised certain key actuarial assumptions utilized in determining estimated ultimate losses, including loss development

Table of Contents

factors. The change in estimate resulted in an increase to “selling, general and administrative expense” on our condensed consolidated statements of operation of $37.6 million during the nine months ended October 1, 2023.

Total accrued self-insurance reserves were $65.5 million, $34.1 million and $44.6 million as of October 1, 2023, January 1, 2023 and October 2, 2022, respectively.

Legal Proceedings

While certain legal proceedings and related indemnification obligations to which we are a party specify the amounts claimed, these claims may not represent reasonably possible losses. Except as noted below, given the inherent uncertainties of litigation, the ultimate outcome of these matters cannot be predicted at this time, nor can the amount of possible loss or range of loss, if any, be reasonably estimated, except in circumstances where an aggregate litigation accrual has been recorded for probable and reasonably estimable loss contingencies. A determination of the amount of accrual required, if any, for these contingencies is made after careful analysis of each matter. The required accrual may change in the future due to new information or developments in each matter or changes in approach such as a change in settlement strategy in dealing with these matters.

Putative Securities Class Action Lawsuit

In February 2020, two putative securities class action complaints were filed against Holdings and certain of its former executive officers (collectively, the “defendants”) in the U.S. District Court for the Northern District of Texas. On March 2, 2020, the two cases were consolidated in an action captioned Electrical Workers Pension Fund Local 103 I.B.E.W. v. Six Flags Entertainment Corp., et al., Case No. 4:20-cv-00201-P (N.D. Tex.) (the “Electrical Workers litigation”), and an amended complaint was filed on March 20, 2020. On May 8, 2020, Oklahoma Firefighters Pension and Retirement System (“Oklahoma Firefighters”) and Electrical Workers Pension Fund Local 103 I.B.E.W. were appointed as lead plaintiffs, Bernstein Litowitz Berger & Grossman LLP was appointed as lead counsel, and McKool Smith PC was appointed as liaison counsel. On July 2, 2020, lead plaintiffs filed a consolidated complaint. The consolidated complaint alleges, among other things, that the defendants made materially false or misleading statements or omissions regarding the Company’s business, operations and growth prospects, specifically with respect to the development of its Six Flags branded parks in China and the financial health of its former partner, Riverside Investment Group Co. Ltd., in violation of the federal securities laws. The consolidated complaint seeks an unspecified amount of compensatory damages and other relief on behalf of a putative class of purchasers of Holdings’ publicly traded common stock during the period between April 24, 2018 and February 19, 2020. On August 3, 2020, defendants filed a motion to dismiss the consolidated complaint. On March 3, 2021, the district court granted defendants’ motion, dismissing the complaint in its entirety and with prejudice.

On August 25, 2021, Co-Lead Plaintiff Oklahoma Firefighters filed a notice of appeal to the U.S. Court of Appeals for the Fifth Circuit (“the Fifth Circuit”) from the district court’s decisions granting defendants’ motion to dismiss, denying plaintiffs’ motion to amend or set aside judgment, and denying plaintiffs’ motion for leave to file a supplemental brief. The appeal was fully briefed as of December 15, 2021, and oral argument was held on March 7, 2022. On January 18, 2023, the Fifth Circuit reversed the dismissal and remanded the case to the district court for further proceedings. On February 9, 2023, the Fifth Circuit mandate issued to the district court. On March 7, 2023, the district court entered a scheduling order governing pre-trial proceedings. On April 18, 2023, Oklahoma Firefighters filed a motion for leave to file an amended complaint that would add a new named plaintiff, remove former Co-Lead Plaintiff Electrical Workers Pension Fund Local 103 I.B.E.W., and modify the case caption. On May 2, 2023, defendants filed an opposition to that motion and a motion for judgment on the pleadings. On June 2, 2023, the district court granted defendants’ motion for judgment on the pleadings, dismissing the case with prejudice, and denied Oklahoma Firefighters’ motions. On June 30, 2023, plaintiffs filed a notice of appeal to the Fifth Circuit from the district court’s decisions. On July 25, 2023, the Fifth Circuit informed the parties that, among other things, the appeal has been docketed, the appellate record is complete, and the Appellant’s brief is due within 40 days. On September 29, 2023, plaintiffs filed the Appellant's brief. On October 4, 2023, the Fifth Circuit informed the parties that defendants' brief is due on November 13, 2023.

We believe this lawsuit is without merit; however, there can be no assurance regarding the ultimate outcome. Regardless of the merit of plaintiff’s claims, litigation may be expensive, time-consuming, disruptive to the Company’s operations and distracting to management. The outcome of this litigation is inherently uncertain, and we cannot reasonably estimate any loss or range of loss that may arise from this matter.

Stockholder Derivative Lawsuits

On March 20, 2020, a putative stockholder derivative lawsuit was filed on behalf of nominal defendant Holdings in the U.S. District Court for the Northern District of Texas against certain of its then-current and former executive officers and directors (the “individual defendants”) in an action captioned Schwartz v. Reid-Anderson, et al., Case No. 4:20-cv-00262-P (N.D. Tex.). In April 2020, two

Table of Contents

additional stockholder derivative lawsuits, making substantially identical allegations as the Schwartz complaint, were filed by Trustees of the St. Clair County Employees’ Retirement System and Mr. Mehmet Ali Albayrak in the U.S. District Court for the Northern District of Texas in actions captioned Martin, et al. v. Reid-Anderson, et al., Case No. 4:20-cv-00311-P (N.D. Tex.) and Albayrak v. Reid-Anderson, et al., Case No. 4:20-cv-00312-P (N.D. Tex.), respectively. On April 8, 2020, plaintiffs in all three of these putative derivative actions moved to consolidate the actions and appoint lead counsel. On May 8, 2020, the district court granted the plaintiffs’ motion to consolidate. The consolidated action is captioned In re Six Flags Entertainment Corp. Derivative Litigation, Case No. 4:20-cv-00262-P (N.D. Tex.). On August 10, 2020, plaintiffs filed a consolidated derivative complaint. The consolidated derivative complaint alleges breach of fiduciary duty, insider selling, waste of corporate assets, unjust enrichment, and contribution for violations of federal securities laws. The consolidated derivative complaint references, and makes many of the same allegations as are set forth in, the Electrical Workers litigation, alleging, among other things, that the individual defendants breached their fiduciary duties, committed waste, are liable for contribution for, or were unjustly enriched by making, failing to correct, or failing to implement adequate internal controls relating to alleged materially false or misleading statements or omissions regarding the Company’s business, operations and growth prospects, specifically with respect to the prospects of the development of Six Flags branded parks in China and the financial health of its former partner, Riverside Investment Group Co. Ltd. The consolidated derivative complaint also alleges that a former officer and director sold shares of the Company while allegedly in possession of material non-public information concerning the same. On September 9, 2020, Holdings and the individual defendants filed a motion to dismiss the consolidated complaint. On April 28, 2021, the district court granted defendants’ motion, dismissing the consolidated complaint in its entirety and with prejudice and denying leave to amend. Plaintiffs’ time to appeal the judgment dismissing this action in its entirety and with prejudice and denying leave to amend lapsed in May 2021.

On May 5, 2020, a putative stockholder derivative lawsuit was filed on behalf of nominal defendant Holdings, by Richard Francisco in Texas state court against certain of its then-current and former executive officers and directors (the “individual defendants”) in an action captioned Francisco v. Reid-Anderson, et al., Case No. DC-20-06425 (160th Dist. Ct., Dallas Cty., Tex.) (the “Francisco action”). The petition in the Francisco action alleges breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. The petition in the Francisco action references, and makes many of the same allegations, as are set forth in the Electrical Workers litigation, alleging, among other things, that the individual defendants breached their fiduciary duties, were unjustly enriched by, abused their control, committed gross mismanagement, and committed waste by making, failing to correct, or failing to implement adequate internal controls relating to alleged materially false or misleading statements or omissions regarding the Company’s business, operations and growth prospects, specifically with respect to the prospects of the development of Six Flags branded parks in China and the financial health of its former partner, Riverside Investment Group Co. Ltd. The petition also alleges that a former officer and director engaged in insider trading. On May 28, 2020, the parties in the Francisco action filed a joint motion to stay proceedings through the resolution of the forthcoming motion to dismiss the Electrical Workers litigation. On June 3, 2020, the district court granted the joint motion to stay proceedings. On June 12, 2020, an additional stockholder derivative lawsuit, making substantially identical allegations as the Francisco petition, was filed on behalf of nominal defendant Holdings in Texas state court by putative stockholder Cliff Bragdon in an action captioned Bragdon v. Reid-Anderson, et al., Case No. DC-20-08180 (298th Dist. Ct., Dallas Cty., Tex.) (the “Bragdon action”). On July 10, 2020, the district court granted an agreed motion filed by the parties in the Francisco and Bragdon actions to consolidate cases, to accept service and an unopposed motion to appoint co-lead and liaison counsel, and to stay both the Francisco and Bragdon actions through final resolution of the motion to dismiss the Electrical Workers litigation. The consolidated state derivative action was captioned In re Six Flags Entertainment Corp. Derivative Litigation, Case No. DC-20-06425 (160th Dist. Ct., Dallas Cty., Tex.). On September 8, 2020, the parties to the consolidated state derivative action filed an agreed motion to transfer the case from Dallas County to Tarrant County, which motion was so ordered on September 27, 2020. The consolidated action is now captioned In re Six Flags Ent. Corp. Derivative Litigation, No. 096-320958-20 (96th Dist. Ct., Tarrant Cty., Tex.). On February 9, 2023, the stay was lifted in the consolidated action when the Fifth Circuit issued the mandate in the Electrical Workers litigation. On April 27, 2023 and May 30, 2023, the parties informed the court that they were conferring, that they would provide a further update within 30 days, and that, in the meantime, the defendants had no obligation to respond to the Francisco or Bragdon complaints or the consolidated action. On June 29, 2023, plaintiffs filed a notice of non-suit without prejudice.

On February 16, 2023, a putative stockholder derivative lawsuit was filed on behalf of nominal defendant Holdings by John Hancock in Texas state court against certain of its former executive officers and directors (the “individual defendants”) in an action captioned Hancock v. Roedel, et al., Case No. 348-340304-23 (348th Dist. Ct., Tarrant Cty., Tex.). Plaintiff refers to and makes many of the same allegations as are set forth in the Electrical Workers litigation, claiming that, among other things, the individual defendants caused Six Flags to make false and misleading statements and omissions about the status of construction of Six Flags branded parks in China and the financial health of its former partner, Riverside Investment Group Co. Ltd. Plaintiff asserts breach of fiduciary duty and unjust enrichment claims. Plaintiff seeks an unspecified amount of monetary damages and equitable relief including, but not limited to, disgorgement. On May 5, 2023, the individual defendants and the Company agreed to accept service of the petition, and plaintiff agreed that the individual defendants and the Company had no obligation to respond to the petition and that defendant’s answer dates are tolled until plaintiff files an amended petition. Plaintiff stated Plaintiff would file an amended petition by June 30, 2023. On August 25, 2023, Plaintiff filed an amended petition. On September 7, 2023, the individual defendants and the Company filed a motion to stay pending

resolution of a duplicative federal derivative action, captioned Dela Cruz v. Reid-Anderson, et al., Case No. 3:23-CV-0396-D (N.D. Tex), and described below. On September 15, 2023, the court granted the motion to stay and ordered the action stayed until 30 days after a ruling by the federal court on the motions to dismiss pending in Dela Cruz v. Reid-Anderson.

On February 22, 2023, a putative stockholder derivative lawsuit was filed on behalf of nominal defendant Holdings by Antonio Dela Cruz in in the U.S. District Court for the Northern District of Texas against certain of its current and former executive officers and directors (the “individual defendants”) in an action captioned Dela Cruz v. Reid-Anderson, et al., Case No. 3:23-CV-0396-D (N.D. Tex.). Plaintiff refers to and makes many of the same allegations as are set forth in the Electrical Workers litigation, claiming that, among other things, the individual defendants caused Six Flags to make false and misleading statements and omissions about the status of construction of Six Flags branded parks in China and the financial health of its former partner, Riverside Investment Group Co. Ltd. Plaintiff asserts contribution, breach of fiduciary duty, and unjust enrichment claims. Plaintiff seeks an unspecified amount of monetary damages and equitable relief including, but not limited to, disgorgement. On June 10, 2023, the court ordered the following schedule: plaintiff’s amended complaint is due on or before August 12, 2023; defendants’ answer or other response was due on or before September 12, 2023; plaintiff’s opposition to defendants’ motion to dismiss was due on or before October 17, 2023; and defendants’ reply to plaintiff’s opposition was filed prior to November 1, 2023. On July 20, 2023, the court scheduled completion of discovery to occur by April 4, 2025, and a four-day trial to begin on September 1, 2025. On August 22, 2023, plaintiff filed an amended complaint. On September 12, 2023, Six Flags and the individual defendants filed motions to dismiss the amended complaint. On October 17, 2023, plaintiff filed oppositions to the defendants' motions to dismiss. Six Flags' and the individual defendants' replies in support of their motions to dismiss were filed by November 1, 2023.

Wage and Hour Class Action Lawsuits

Holdings and/or certain of its consolidated subsidiaries are named defendants in various lawsuits generally alleging violations of federal and/or state laws regulating wage and hour pay. Plaintiffs in these lawsuits seek monetary damages, including unpaid wages, statutory penalties, and/or attorneys’ fees and costs. Regardless of the merits of particular suits, litigation may be expensive, time-consuming, disruptive to the Company’s operations and distract management from the operation of our business. In recognition of these impacts on the business, the Company may enter into settlement agreements or other arrangements to settle litigation and resolve such disputes. No assurance can be given that such agreements can be obtained on acceptable terms or at all, or that litigation will not occur. These agreements may also significantly increase the Company’s operating expenses. The outcomes of these lawsuits are inherently uncertain, and we cannot reasonably estimate any loss or range of loss that may arise from these matters in excess of the amounts that we have recognized for these lawsuits, which amounts are not material to our consolidated financial statements.

Personal Injury Lawsuit

On November 18, 2021, the Texas Judicial Panel on Multidistrict Litigation consolidated numerous lawsuits filed against Six Flags Splashtown, LLC d/b/a Six Flags Hurricane Harbor Splashtown asserting claims arising from an alleged chemical vapor release on July 17, 2021 at Six Flags Splashtown. Certain plaintiffs have also named unaffiliated third parties as additional defendants. The consolidated multidistrict litigation is captioned In re Six Flags Splashtown Litigation (Master File No. 2021-77214), and is pending in the 295th Judicial District Court in Harris County, Texas. Plaintiffs are seeking compensatory and punitive damages. On April 14, 2023, Six Flags Splashtown settled with 421 plaintiffs, including all bellwether plaintiffs set for trial on April 17, 2023, for an immaterial amount. On September 22, 2023, the Park settled with 55 additional plaintiffs, including the bellwether plaintiffs set for trial on January 15, 2024, for an immaterial amount. These settlements resolved claims brought by these plaintiffs only and do not resolve all claims arising from the alleged chemical vapor release. There are 19 remaining plaintiffs represented by different firms. All pro se plaintiffs have been dismissed. The parties are working to document these settlements and have asked the Court to appoint special masters to determine the amounts each settling plaintiff will receive. Regardless of the merit of particular claims, litigation may be expensive, time-consuming, disruptive to the Company’s operations and distracting to management. In recognition of these considerations, the Company may enter into further settlement agreements or other arrangements to settle litigation and resolve such disputes. No assurance can be given that such agreements can be obtained on acceptable terms or that litigation will not occur. These agreements may also significantly increase the Company’s operating expenses. The outcome of this litigation is inherently uncertain, and we cannot reasonably estimate any loss or range of loss that may arise from the remaining matters in excess of the amount that we have recorded for this litigation, which amount is not material to our consolidated financial statements.

Litigation Relating to Routine Proceedings

We are also engaged from time to time in other routine legal and tax proceedings incidental to our business. We do not believe that any of these routine proceedings will have a material impact on the business or our financial condition.

Securities and Exchange Commission Investigation

The Securities and Exchange Commission is conducting an investigation into the Company’s disclosures and reporting made in 2018 through February 2020 related to its business, operations and growth prospects of its Six Flags branded parks in China and the financial health of its former business partner, Riverside Investment Group Co. Ltd. The Company received a document subpoena in February 2020 and subsequently certain current and former executives received subpoenas in connection with this matter and they continue to provide responsive information. The Company is fully cooperating and is committed to continuing to cooperate fully with the SEC in this matter. We cannot predict the length, scope or results of the investigation, or the impact, of the investigation on our results of operations, business or financial condition.

7. Business Segments

Our chief operating decision maker “CODM” regularly receives consolidated information which is used to make strategic decisions. Each individual park location has a Park President or General Manager responsible for the operational results and executing the strategy set forth by the CODM. Substantially all of our parks provide similar products and services through a similar process to the same class of customer through a consistent method. We also believe that the parks share common economic characteristics. Based on these factors, we have only one reportable segment - parks.

The following information reflects our goodwill and long-lived assets (which consists of property and equipment, right-of-use operating leases and intangible assets) as of October 1, 2023, January 1, 2023, and October 2, 2022:

9. Stock Repurchase Plans and Shareholder Rights Plan

On March 30, 2017, Holdings announced that its Board of Directors approved a stock repurchase plan that permits Holdings to repurchase an incremental $500.0 million in shares of Holdings’ common stock (the "March 2017 Stock Repurchase Plan"). As of October 1, 2023, Holdings had repurchased 8,071,000 shares at a cumulative cost of approximately $365.1 million and an average price per share of $45.24 under the March 2017 Stock Repurchase Plan, leaving approximately $134.9 million available for permitted repurchases. We have not made any repurchases during the nine months ended October 1, 2023.

10. Revision to Previously Reported Financial Information

During the third quarter of 2023, we identified an accounting error for our stock-based compensation expense related to the recognition of expense for dividend equivalent rights ("DERs"). The error primarily relates to the inadvertent reversal of stock-based compensation expense for vested DERs for periods beginning in the first quarter of 2020 through the fourth quarter of 2022. We have assessed the error and concluded that it was not material to any prior periods. However, the aggregate amount of the error would have been material to our condensed consolidated financial statements in the current period. Therefore, we have revised our previously issued financial information. Prior periods not presented herein will be revised, as applicable, in future filings.

The following table presents the impact of correcting the error previously discussed on the affected line items of our condensed consolidated balance sheet as of October 2, 2022.

11. Subsequent Event

On November 2, 2023, we announced that we entered into a definitive Merger agreement to combine with Cedar Fair L.P. (“Cedar Fair”) (NYSE: FUN). Subject to the terms and conditions set forth in the Merger agreement, each issued and outstanding common share of Six Flags will be converted into the right to receive 0.58 shares of common stock of the new combined entity (subject to certain exceptions and as the same may be adjusted). Following the close of the transaction, holders of Six Flags common stock will own approximately 48.8% of the outstanding shares of the combined company, and the holders of units of Cedar Fair limited partnership interest will own approximately 51.2% of the outstanding shares of the combined company. One business day prior to the close of the transaction, Six Flags will declare a special cash dividend composed of: (i) a fixed amount of $1.00 per outstanding Six Flags share,

totaling approximately $85 million in the aggregate, plus, (ii) an amount per outstanding Six Flags share equal to (a) the aggregate per unit distributions declared or paid by Cedar Fair to unitholders with a record date following today’s date and prior to the close of the transaction, multiplied by (b) the Six Flags Exchange Ratio, which special dividend will be payable to Six Flags shareholders of record as of one business day prior to the close of the transaction, contingent on the closing of the transaction.

The Merger is expected to close in the first half of 2024, following receipt of Six Flags' stockholder approval, regulatory approvals, and satisfaction of other customary closing conditions.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis contain forward-looking statements relating to future events or our future financial performance, which involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements. Please see the discussion regarding forward-looking statements included under the caption "Cautionary Note Regarding Forward-Looking Statements" included elsewhere in this Quarterly Report and "Item 1A. Risk Factors" in the 2022 Annual Report and in this Quarterly Report for further discussion of the uncertainties, risks and assumptions associated with these statements.

The following discussion and analysis present information that we believe is relevant to an assessment and understanding of our condensed consolidated balance sheets and results of operations. This information should be read in conjunction with the condensed consolidated financial statements, and the notes thereto, and other financial data included elsewhere in this Quarterly Report. The following information should also be read in conjunction with our audited consolidated financial statements, and the notes thereto, and "Management’s Discussion and Analysis of Financial Condition and Results of Operations" in the 2022 Annual Report.

Use of Certain Per Capita Metrics

We use certain per capita metrics that are non-GAAP measures of the performance of our business on a per guest basis and believe that these metrics provide relevant and useful information for investors because they assist in comparing our operating performance on a consistent basis, make it easier to compare our results with those of other companies in our industry and allows investors to review performance in the same manner as our management.

•Total guest spending per capita is the total revenue generated from our guests, on a per guest basis, through admissions and in-park spending. Total guest spending per capita is calculated by dividing the sum of park admissions revenue and park food merchandise and other revenue by total attendance.

•Admissions revenue per capita is the total revenue generated from our guests, on a per guest basis, to enter our parks. Admissions revenue per capita is calculated by dividing park admission revenue by total attendance.

•In-park spending per capita is the total revenue generated from our guests, on a per guest basis, on items sold within our parks, such as food and beverages, games and merchandise. In-park spending per capita is calculated by dividing park food, merchandise and other revenue by total attendance.

Overview

General

We are the largest regional theme park operator in the world and the largest operator of water parks in North America based on the number of parks we operate. Of our 27 regional theme parks and water parks, 24 are located in the United States, two are located in Mexico and one is located in Montreal, Canada. Our parks are located in geographically diverse markets across North America and generally offer a broad selection of state-of-the-art and traditional thrill rides, water attractions, themed areas, concerts and shows, restaurants, game venues and retail outlets, providing a complete family-oriented entertainment experience. We work continuously to improve our parks and our guests’ experiences to meet our guests’ evolving preferences.

The results of operations for the three and nine months ended October 1, 2023 and October 2, 2022, are not indicative of the results expected for the full year. Typically, our park operations generate approximately 70% - 75% of their annual revenue during the second and third quarter each year while certain expenses are incurred year-round.

Our revenue is derived from (i) the sale of tickets (including season passes and other multi-use products) for entrance to our parks, (ii) the sale of food and beverages, merchandise, games and attractions, parking and other services inside our parks, and (iii) sponsorship, international agreements and accommodations. Revenue from ticket sales and in-park sales are primarily impacted by park attendance and average pricing of our admission products and in-park offerings. Revenue from sponsorship, international agreements and accommodations can be impacted by the term, timing and extent of services and fees under these arrangements, which can result in fluctuations from quarter to quarter and year to year.

Our principal costs of operations include salaries and wages, employee benefits, advertising, third party services, repairs and maintenance, utilities, rent and insurance. A large portion of our expenses is relatively fixed when our parks are operating, as our costs for full-time employees, maintenance, utilities, rent, and insurance do not vary significantly with attendance.

Table of Contents

We anticipate that the tight labor market and recent increases to the minimum wage rates will increase our salary, wage and benefit expenses in 2023 and future years. Further legislative changes and competitive wage rate pressure could cause these expenses to continue to increase in the future.

Merger Agreement with Cedar Fair

On November 2, 2023, we announced that we entered into a definitive merger agreement to combine with Cedar Fair L.P. (“Cedar Fair”) (NYSE: FUN). Subject to the terms and conditions set forth in the merger agreement, each issued and outstanding common share of Six Flags will be converted into the right to receive 0.58 shares of common stock of the new combined entity (subject to certain exceptions and as the same may be adjusted). Following the close of the transaction, holders of Six Flags common stock will own approximately 48.8% of the outstanding shares of the combined company, and the holders of units of Cedar Fair limited partnership interest will own approximately 51.2% of the outstanding shares of the combined company. One business day prior to the close of the transaction, Six Flags will declare a special cash dividend composed of: (i) a fixed amount of $1.00 per outstanding Six Flags share, totaling approximately $85 million in the aggregate, plus, (ii) an amount per outstanding Six Flags share equal to (a) the aggregate per unit distributions declared or paid by Cedar Fair to unitholders with a record date following today’s date and prior to the close of the transaction, multiplied by (b) the Six Flags Exchange Ratio, which special dividend will be payable to Six Flags shareholders of record as of one business day prior to the close of the transaction, contingent on the closing of the transaction.

The merger is expected to close in the first half of 2024, following receipt of Six Flags' stockholder approval, regulatory approvals, and satisfaction of other customary closing conditions.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent liabilities as of the date of the financial statements and the reported amounts of revenues and expenses earned and incurred during the reporting period. Critical accounting estimates are fundamental to the portrayal of both our financial condition and results of operations and often require difficult, subjective and complex estimates and judgments. We evaluate our estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which we believe to be reasonable under the circumstances. We adjust such estimates and assumptions when facts and circumstances dictate. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in these estimates resulting from the continuing changes in the economic environment will be reflected in the financial statements in future periods. With respect to our critical accounting policies and estimates, there have been no material developments or changes from the policies and estimates discussed in the 2022 Annual Report.

Total guest spending per capita	$	56.37	$	60.96	$	(4.59)	(8)	%

Revenue

Revenue for the three months ended October 1, 2023, totaled $547.5 million, an increase of $42.6 million, or 8%, compared to $504.8 million for the three months ended October 2, 2022. The increase was attributable to an attendance increase of 16% and an increase in sponsorship, international agreements and accommodations revenue of $9.2 million. The increase was partially offset by a decrease in per capita spending.

Total guest spending per capita, which excludes sponsorship, international agreements and accommodations revenue, for the three months ended October 1, 2023, decreased by $4.59, to $56.37, compared to the three months ended October 2, 2022, driven by a $4.07, or 12%, decrease in admissions revenue per capita and a $0.52, or 2%, decrease in in-park spending per capita. The decrease in admissions spending per capita was driven primarily by the planned effort to optimize season pass and single-day ticket pricing, which resulted in lower average admissions pricing in third quarter 2023 versus third quarter 2022. The decrease in in-park spending per capita was driven primarily by lower spend on parking, retail, and flash passes, resulting from a higher mix of attendance from season passes in third quarter 2023 versus the prior year. Due to certain benefits available to season pass holders, guests visiting on a season pass spend less per visit on certain in-park products than guests visiting on a single-day ticket. The season pass mix-driven decline in in-park spending per capita was partially offset by higher food and beverage sales in third quarter 2023 versus the prior year.

Operating expenses

Operating expenses for the three months ended October 1, 2023, increased $25.5 million, or 14%, compared to the three months ended October 2, 2022, which was primarily attributable to wage increases for our seasonal labor, higher costs associated with an earlier start to our fall events and investments in new entertainment shows and events and an increase in repairs and maintenance expense.

Table of Contents

Selling, general and administrative expenses

Selling, general and administrative expenses for the three months ended October 1, 2023, increased $17.5 million, or 43%, compared to the three months ended October 2, 2022. The increase was primarily attributable to a $12.9 million increase in advertising expense.

Cost of products sold

Cost of products sold in the three months ended October 1, 2023, increased $2.7 million, or 7%, compared to the three months ended October 2, 2022, primarily as a result of higher unit sales resulting from higher attendance.

Depreciation and amortization

Depreciation and amortization expense for the three months ended October 1, 2023, decreased $2.2 million, or 7%, compared to the period ended October 2, 2022. The decrease in depreciation and amortization expense is primarily the result of a higher proportion of our capital expenditures over the past several years that have been allocated to assets with shorter useful lives.

Loss on disposal of assets

We recognized a loss on disposal of assets of $1.8 million during the three months ended October 1, 2023, and a loss on disposal of assets of $5.0 million during the three months ended October 2, 2022. These losses were related to the disposition of older rides and other assets in the normal course of operations.

Interest expense, net

Interest expense, net for the three months ended October 1, 2023, increased $4.1 million, or 12%, compared to the three months ended October 2, 2022. The increase is attributable to higher interest rates on the 2031 Notes as compared to the 2024 Notes which were outstanding in the prior year and increases in interest rates on our floating-rate debt related to our Term Loan B and Revolving Credit Facility.

Income tax expense

Income tax expense for the three months ended October 1, 2023 was $36.6 million reflecting an effective tax rate of 21.4%. The difference between our effective tax rate and the federal statutory rate primarily results from state and foreign income taxes and certain nondeductible expenses, including nondeductible executive compensation. Income tax expense for the three months ended October 2, 2022 was $38.7 million reflecting an effective tax rate of 22.2%. The difference between the federal statutory rate and our effective tax rate was due to a $4.0 million discrete tax item associated with our operations in Mexico, as well as state and foreign income taxes and nondeductible expenses, including certain nondeductible executive compensation.

Total guest spending per capita	$	60.28	$	63.63	$	(3.35)	(5)	%

Revenue

Revenue for the nine months ended October 1, 2023, totaled $1,133.4 million, an increase of $55.0 million, or 5%, compared to the $1,078.4 million for the nine months ended October 2, 2022. The increase was primarily attributable to an increase in attendance of 10% and a $14.8 million increase in sponsorship, international agreement and accommodations revenue. The increase was partially offset by reduced spending on a per capita basis.

Total guest spending per capita, which excludes sponsorship, international agreements and accommodations revenue, for the nine months ended October 1, 2023, decreased $3.35, to $60.28, compared to the nine months ended October 2, 2022, driven by a decrease in admissions revenue per capita of $2.84, or 8%, and a decrease in in-park spending per capita of $0.51, or 2%. The decrease in admissions spending per capita was driven primarily by the planned effort to optimize season pass and single-day ticket pricing, which resulted in lower average admissions pricing for the nine months ended October 1, 2023 compared to the nine months ended October 2, 2022. The decrease in in-park spending per capita was driven primarily by lower spend on parking, retail, and flash passes, resulting from a higher mix of attendance from season passes in first nine months 2023 versus the prior year. Due to certain benefits available to season pass holders, guests visiting on a season pass spend less per visit on certain in-park products than guests visiting on a single-day ticket. The season pass mix-driven decline in in-park spending per capita was partially offset by higher food and beverage sales in first nine months 2023 versus the prior year.

Operating expenses

Operating expenses for the nine months ended October 1, 2023, increased $25.0 million, or 5%, compared to the nine months ended October 2, 2022, primarily as a result of an increase in labor costs and the addition or extension of multiple events during the year including Viva la Fiesta, Flavors of the World and Scream Break.

Table of Contents

Selling, general and administrative expenses

Selling, general and administrative expenses for the nine months ended October 1, 2023, increased $57.5 million, or 42%, compared to the nine months ended October 2, 2022. The increase was primarily attributable to an increase in our self-insurance reserves of $37.6 million. See Note 6 - Commitments and Contingencies, for additional information on the change in accounting estimate that resulted in this adjustment. The remaining increase was primarily driven by an increase in our advertising spending compared to the prior period.

Cost of products sold

Cost of products sold for the nine months ended October 1, 2023 increased $1.4 million, or 2%, compared to the nine month period ended October 2, 2022, primarily due to higher unit sales resulting from higher attendance.

Depreciation and amortization

Depreciation and amortization expense for the nine months ended October 1, 2023, decreased $0.8 million, or 1%, compared to the nine months ended October 2, 2022. The decrease in depreciation and amortization expense is primarily the result of a higher proportion of our capital expenditures over the past several years that have been allocated to assets with shorter useful lives.

Loss on disposal of assets

We recognized a $6.7 million loss on disposal of assets for the nine months ended October 1, 2023, compared to a loss on disposal of assets of $3.0 million for the nine months ended October 2, 2022. The loss on disposal of assets during the nine months ended October 1, 2023, was driven by the disposition of older rides and other assets in the normal course of operations. The loss on disposal of assets during the nine months ended October 2, 2022 was partially offset by insurance proceeds of $2.0 million received under our property insurance policy for losses incurred.

Interest expense, net

Interest expense, net for the nine months ended October 1, 2023, increased $10.4 million, or 10%, compared to the nine months ended October 2, 2022. The increase is primarily attributable to an increase in the cost of our floating rate debt and increased borrowings on our Revolving Credit Facility. The higher borrowings under our Revolving Credit Facility are primarily attributable to additional borrowings used to fund the portion of the tender of our 2024 Notes not covered by the net proceeds of the 2031 Notes.

Loss on debt extinguishment

Loss on debt extinguishment was $14.0 million for the nine months ended October 1, 2023 as compared to compared to a loss of debt extinguishment of $17.5 for nine months ended October 2, 2022. During the nine months ended October 1, 2023, we recognized a loss on debt extinguishment of $14.0 million due to the write-off of unamortized deferred financing costs on the 2024 Notes, the premium paid above par on the early redemption of the 2024 Notes and the transaction costs charged to expense. During the nine months ended October 2, 2022, we incurred a $17.5 million loss on debt extinguishment upon the early redemption of $360.0 million of the 2025 Notes comprised of $12.6 million for the premium paid above par and $5.0 million for the write-off of the pro rata amount of unamortized deferred financing costs associated with the 2025 Notes that were redeemed early.

Income tax expense

Income tax expense for the nine months ended October 1, 2023 was $32.5 million, an effective tax rate of 23.0%. The difference between our effective tax rate and the federal statutory rate primarily results from state and foreign income taxes and certain nondeductible expenses, including nondeductible executive compensation. Income tax expense for the nine months ended October 2, 2022, was $44.3 million, an effective tax rate of 24.6%. The difference between the federal statutory rate and our effective tax rate was due to a $4.0 million discrete tax item associated with our operations in Mexico, as well as state and foreign income taxes and nondeductible expenses, including certain nondeductible executive compensation.

Calculation of EBITDA for the three and nine months ended October 1, 2023 and October 2, 2022

We manage our business primarily with three different metrics; Modified EBITDA, Adjusted EBITDA and Adjusted EBITDA minus CAPEX.

Table of Contents

“Modified EBITDA,” a non-GAAP measure, is defined as our consolidated income (loss) from continuing operations excluding the following: the cumulative effect of changes in accounting principle, discontinued operations, income tax expense or (benefit), restructure costs or recoveries, reorganization items (net), other (income) expense, (gain) loss on debt extinguishment, equity in (income) loss of investees, interest expense (net), (gain) loss on disposal of assets, (gain) loss on the sale of investees, amortization, depreciation, stock-based compensation, fresh start accounting valuation adjustments and other significant non-recurring items. Modified EBITDA, as defined herein, may differ from similarly titled measures presented by other companies. Management uses non-GAAP measures for budgeting purposes, measuring actual results and allocating resources. We believe that Modified EBITDA provides relevant and useful information for investors because it assists in comparing our operating performance on a consistent basis, makes it easier to compare our results with those of other companies in our industry as it most closely ties our performance to that of our competitors and allows investors to review performance in the same manner as our management.

"Adjusted EBITDA," a non-GAAP measure, is defined as Modified EBITDA minus the interests of third parties in the Modified EBITDA of properties that are less than wholly owned (consisting of Six Flags Over Georgia, Six Flags White Water Atlanta and Six Flags Over Texas). Adjusted EBITDA is approximately equal to “Parent Consolidated Adjusted EBITDA” as defined in our secured credit agreement, except that Parent Consolidated Adjusted EBITDA excludes Adjusted EBITDA from equity investees that is not distributed to us in cash on a net basis and has limitations on the amounts of certain expenses that are excluded from the calculation. Adjusted EBITDA as defined herein may differ from similarly titled measures presented by other companies. Our board of directors and management use Adjusted EBITDA to measure our performance and our current management incentive compensation plans are based largely on achieving specified Adjusted EBITDA targets. We believe that Adjusted EBITDA is frequently used by analysts and most investors as their primary measure of our performance in the evaluation of companies in our industry. In addition, the instruments governing our indebtedness use Adjusted EBITDA to measure our compliance with certain covenants and, in certain circumstances, our ability to make certain borrowings. During 2023, we reclassified the net pension-related expense (benefit) to other (income) expense, net, in our condensed consolidated statements of operations. This reclassification has been reflected in all periods presented. As a result of this reclassification, Adjusted EBITDA for the three-month and nine month periods ended October 2, 2022, declined by $1.6 million and $4.0 million, respectively, as compared to the amounts previously reported.

“Adjusted EBITDA minus capex,” a non-GAAP measure, is defined as Adjusted EBITDA minus capital expenditures net of property insurance recoveries. Adjusted EBITDA minus capex as defined herein may differ from similarly titled measures presented by other companies.

Modified EBITDA, Adjusted EBITDA and Adjusted EBITDA minus capex are not recognized terms under US GAAP and should not be considered in isolation or as a substitute for a measure of our financial performance prepared in accordance with US GAAP. These metrics are not indicative of income or loss as determined under US GAAP. Modified EBITDA, Adjusted EBITDA and Adjusted EBITDA minus capex as presented may not be comparable to similarly titled measures of other companies due to varying methods of calculation.

The following tables set forth a reconciliation of net income to Modified EBITDA, Adjusted EBITDA and Adjusted EBITDA minus capex for the three and nine month periods ended October 1, 2023 and October 2, 2022:

Table of Contents

______________________________________
(1) Amount relates to an adjustment to our self-insurance reserves resulting from a change in accounting estimate that increased our ultimate loss indications on both identified claims and incurred but not reported claims. See Note 6 – Commitment and Contingencies for additional information regarding this change in accounting estimate. We have excluded this adjustment from our reported Adjusted EBITDA because we believe (i) the change in actuarial assumptions and related change in accounting estimate that rise to adjustment is unusual and not expected to be recurring; (ii) excluding it provides more meaningful comparisons to our historical results; and (iii) excluding it provides more meaningful comparisons to other companies in our industry.

Liquidity, Capital Commitments and Resources

Our principal sources of liquidity are cash generated from operations, funds from borrowings and existing cash on hand. Our principal uses of cash include the funding of our operations, including interest payments on our outstanding debt obligations, capital expenditures and payments to our partners in the Partnership Parks.

We did not pay any dividends during the nine months ended October 1, 2023, and we paid a nominal amount in the nine months ended October 2, 2022 to employees with dividend equivalent rights for previously declared dividends due upon the vesting of the related shares.

As of October 1, 2023, we have repurchased 8,071,000 shares of common stock at a cumulative cost of approximately $365.1 million and an average cost per share of $45.24 under our approved stock repurchase program, leaving approximately $134.9 million available for permitted repurchases.

Based on historical and anticipated future operating results, we believe cash flow from operations, available cash and amounts available under our Revolving Credit Facility will be adequate to meet our liquidity needs, including any anticipated requirements for working capital, capital expenditures, scheduled debt service and obligations under arrangements relating to the Partnership Parks. Additionally, we expect to utilize federal net operating loss carryforwards to reduce our cash tax obligations through fiscal year 2024.

Our current and future liquidity is greatly dependent upon our operating results, which are driven largely by overall economic conditions as well as the price and perceived quality of the entertainment experience at our parks. Our liquidity could also be adversely affected by a disruption in the availability of credit as well as unfavorable weather; natural disasters; contagious diseases, such as Ebola, Zika, swine flu, COVID-19, Monkeypox or other diseases; accidents or the occurrence of an unfavorable event at one or more of our parks, including terrorist acts or threats inside or outside of our parks; negative publicity; or significant local competitive events, which could materially reduce paid attendance and revenue related to that attendance at any of our parks. While we work with local police authorities on security-related precautions to prevent certain types of disturbances, we can make no assurance that these precautions will be able to prevent these types of occurrences. However, we believe our ownership of many parks in different geographic locations reduces the effects of adverse weather and other adverse events on our consolidated results. If such an adverse event were to occur, we may be unable to borrow under the Revolving Credit Facility or may be required to repay amounts outstanding under the Revolving Credit Facility and/or we may need to seek additional financing. In addition, we expect that we will be required to seek additional financing to refinance all or a significant portion of our existing debt on or prior to maturity. The degree to which we are leveraged could adversely affect our ability to obtain any additional financing. See "Cautionary Note Regarding Forward-Looking Statements" and "Item 1A. Risk Factors" in the 2022 Annual Report and in this Quarterly Report.

As of October 1, 2023, the principal amount of our total indebtedness, was $2,289.9 million. As of October 1, 2023, based on (i) non-revolving credit debt outstanding, (ii) anticipated levels of working capital revolving borrowings during 2023 and 2024, and (iii) required interest payments due to holders of the 2024 Notes, the 2025 Notes, the 2027 Notes and the 2031 Notes, we anticipate annual cash interest payments of approximately $165 million and $155 million during 2023 and 2024, respectively.

As of October 1, 2023, we had $66.8 million of unrestricted cash and $390.0 million available for borrowing under the Revolving Credit Facility. Our ability to borrow under the Revolving Credit Facility is contingent on our compliance with certain conditions, including a maximum senior secured net leverage maintenance covenant, a minimum liquidity covenant and the absence of any material adverse change in our business or financial condition. If we were to become unable to borrow under the Revolving Credit Facility, and our operating results significantly underperform our expectations, we may be unable to pay in full our obligations. A default under the Revolving Credit Facility could permit the lenders under the Credit Facility to accelerate the obligations thereunder. The Revolving Credit Facility expires in May 2028. The terms and availability of the Credit Facility and other indebtedness are not affected by changes in the ratings issued by rating agencies in respect of our indebtedness. As of October 1, 2023, we are in compliance with all covenants. For a more detailed description of our indebtedness, see Note 3 - Long-term indebtedness to the unaudited condensed consolidated financial statements included in this Quarterly Report.

2031 Notes Issuance and Tender Offer

On April 26, 2023, the Company launched a private offering of up to $800 million aggregate principal amount of senior notes. Concurrently, the Company commenced a cash tender offer (the “Tender Offer”) for any and all outstanding 2024 Notes. On May 3, 2023, we repaid $892.6 million, or 94.0% of the aggregate principal amount of the 2024 Notes that were tendered to us. The remainder of the 2024 Notes is due in July 2024.

On May 3, 2023, the Company completed the private sale of the 2031 Notes at an offering price of 99.248% of the principal amount thereof. Net of the original issuance discount and debt issuance costs, the Company received net proceeds of $784.0 million. We incurred a $13.9 million loss on debt extinguishment comprised of $1.0 million for the premium paid above par and $12.9 million of costs charged to expense on debt modification which were recognized during the three months ended July 2, 2023.

Also, on May 3, 2023, the Company announced that $892.6 million, or 94.0% of the aggregate principal amount of the 2024 notes were validly tendered pursuant to the Tender Offer. Net cash proceeds from the 2031 Notes, together with other available cash, including borrowings under our Revolving Credit Facility, were used to pay the Purchase Price, plus accrued and unpaid interest.

Investments

We regularly make capital investments for new rides and attractions in our parks. In addition, we make capital investments in the food, retail and other in-park areas. We also make enhancements to theming and landscaping of our parks in order to provide a more complete, family-oriented entertainment experience; and invest in our information technology infrastructure to attain operational efficiencies. We regularly perform maintenance capital enhancements, with most expenditures made during the off-season. Repairs and maintenance costs for recurring and routine maintenance are expensed as incurred and are not included in capital expenditures.

Cash Flows


	Nine Months Ended
(Amounts in thousands)	October 1, 2023		October 2, 2022
Net cash provided by operating activities	$	247,258	$	193,812
Net cash used in investing activities	(109,282)		(73,383)
Net cash used in financing activities	(154,643)		(383,229)
Effect of exchange rate on cash	3,308		529
Net decrease in cash and cash equivalents	$	(13,359)	$	(262,271)

During the nine months ended October 1, 2023, net cash provided by operating activities was $247.3 million, compared to net cash provided by operating activities of $193.8 million during the nine months ended October 2, 2022. The increase was primarily driven by an increase in deferred revenue from the sale of multi-use admissions products as compared to the prior year period. Net cash used in investing activities was $109.3 million for the nine months ended October 1, 2023, compared to net cash used in investing activities of $73.4 million in the nine months ended October 2, 2022. The increase was primarily attributable to a planned increase in capital spending. Net cash used in financing activities was $154.6 million for the nine months ended October 1, 2023, compared to $383.2 million for the nine months ended October 2, 2022. During 2023, the amount is driven by the repayment of $892.0 million of the 2024 Notes offset by the $784.0 million in proceeds received from the issuance of the 2031 Notes, and additional borrowings under the Revolving Credit Facility. The $383.2 million in 2022 was driven by the repayment of $360.0 million of the 2025 Notes and share repurchases of $96.8 million, partially offset by increased borrowings under our Revolving Credit Facility.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

As of October 1, 2023, there were no material changes in our market risk exposure from that disclosed in the 2022 Annual Report.

ITEM 4. CONTROLS AND PROCEDURES

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation, as of October 1, 2023, of the effectiveness of our disclosure controls and procedures, as such term is defined under Rule 13a-15(e) or 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Based on this evaluation, our Chief Executive Officer and our Chief Financial Officer concluded that, as of the end of such period, our disclosure controls and procedures are effective to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and (ii) accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting. As required by Exchange Act Rule 13a-15(d), the Company's management, including the Chief Executive Officer and Chief Financial Officer, also conducted an evaluation of the Company's internal control over financial reporting to determine whether any change occurred during the last fiscal quarter of the period covered by this report that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. Based on that evaluation there has been no change in the Company’s internal control over financial reporting during the last fiscal quarter of the period covered by this report other than certain internal control changes related to the implementation of new accounting and financial reporting system that has materially affected, or is reasonably likely to materially affect the Company's internal control over financial reporting.

PART II — OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The nature of the industry in which we operate tends to expose us to claims by guests, generally for injuries. Accordingly, we are party to various legal actions arising in the normal course of business. Historically, the great majority of these claims have been minor. Although we believe that we are adequately insured against guests’ claims, if we become subject to damages that cannot by law be insured against, such as punitive damages or certain intentional misconduct by employees, there may be a material adverse effect on our operations.

For information regarding legal proceedings, see Note 15, Commitments and Contingencies, to the consolidated financial statements in the 2022 Annual Report, and Note 6, Commitments and Contingencies, to the unaudited condensed consolidated financial statements in this Quarterly Report.

ITEM 1A. RISK FACTORS

In addition to the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended January 1, 2023, the following risk factors have been identified as a result of Six Flags Entertainment Corporation entering into a merger agreement with Cedar Fair, L.P. ("Cedar Fair").

Table of Contents

Risks Related to the Proposed Merger

If the conditions to the Merger Agreement are not met, the Merger may not occur.

Even if the Merger Agreement is approved by the stockholders of Holdings, specified conditions must be satisfied or waived before the parties to the Merger Agreement are obligated to complete the Merger. The Company does not control the satisfaction of all of such conditions. The Company and Cedar Fair may not satisfy all of the closing conditions in the Merger Agreement. If the closing conditions are not satisfied or waived, the Merger will not occur, or will be delayed pending later satisfaction or waiver, and such delay may cause the Company and Cedar Fair to each lose some or all of the intended benefits of the Merger.

The Merger agreement may be terminated in accordance with its terms, and the Merger may not be completed, which could negatively impact our business, financial results, and/or stock price.

The Merger agreement is subject to a number of conditions which must be fulfilled in order to complete the merger, including approval of Six Flags' stockholders. If the Merger is not completed for any reason, there may be adverse consequences and we may experience negative reactions from the financial markets, our customers, our vendors and/or our employees.

The proposed Merger and integration of the Company and Cedar Fair may be more difficult, costly, or time-consuming than expected, and we may fail to realize the anticipated benefits of the merger.

The success of the proposed Merger will depend in part on our ability to realize anticipated revenue and cost synergies and on our ability to successfully integrate the businesses. If we are not able to successfully achieve these objectives, the anticipated benefits of the Merger may not be realized fully, or at all, or may take longer to realize than expected. In addition, our ability to achieve the goals for the proposed Merger may be affected by future prospects, execution of business strategies, and our ability to manage the various factors discussed within this report, including within the forward-looking statements. The actual benefits of the proposed Merger also could be less than anticipated if, for example, completion of the Merger and/or integration of the businesses are more difficult, costly or time-consuming than we expect.

We have incurred and expect to incur substantial costs, fees, expenses, and charges related to the Merger and integration, and may incur additional costs we do not currently anticipate.

We have incurred and expect to incur additional costs, fees, expenses, and charges related to the Merger and integration. We may incur additional costs that we do not currently anticipate. These costs include and may include legal, financial advisory, accounting, consulting, and other advisory fees, retention, severance and employee benefit-related costs, public company filing fees and other regulatory fees, as well as closing, integration and other related costs. Some of the costs are payable regardless of whether or not the Merger is completed.

We may be unable to retain personnel successfully while the Merger is pending or after the Merger is completed.

The success of the Merger will depend in part on our ability to retain key employees while the Merger is pending or after the Merger is consummated. If we are unable to retain key employees, including management, who are critical to the successful completion, integration and future operation of the combined company, we could face disruption in our operations, loss of key information, expertise or know-how, or unanticipated recruiting costs, which may impact our ability to achieve our goals related to the transaction.

The announcement or completion of the proposed Merger may disrupt and/or harm our current plans and operations or those of Cedar Fair, may divert management's time and attention and may affect existing business relationships, any of which may impact financial performance, operating results and/or our ability to achieve the benefits of the Merger.

The announcement or completion of the proposed Merger may disrupt and/or harm our current plans and operations and/or those of Cedar Fair. Management’s time and attention also may be diverted on transaction-related issues. There also may be adverse reactions to or changes in business relationships as a result of the announcement or completion of the Merger. Any of these factors could affect our and/or Cedar Fairs’ financial performance or operating results, and/or could impact our ability to achieve the benefits of the Merger.

Regulatory approvals may not be received, may take longer than expected, or may impose conditions that are not presently anticipated or that affect the anticipated benefits of the Merger.

Before the Merger may be completed, various approvals, consents and non-objections must be obtained from regulatory authorities in the United States and Mexico. These approvals could be delayed or not obtained at all, which could disrupt operations, or could delay or adversely affect completion of the Merger. The approvals that are granted may impose terms and conditions, including requiring the

Table of Contents

parties to seek divestitures of substantial assets, limitations, obligations or costs, or place restrictions on the conduct of the combined company's business or require changes to the terms of the transactions contemplated by the Merger agreement, which could affect the anticipated benefits of the Merger.

Litigation relating to the proposed Merger may be filed against Cedar Fair, us and/or each company's board of directors that could prevent or delay the closing and/or result in the payment of damages.

In connection with the proposed Merger, it is possible that the unitholders of Cedar Fair and/or our stockholders may file lawsuits against Cedar Fair, us and/or each company's board of directors. Among other remedies, these stockholders and/or unitholders could seek damages and/or to enjoin the Merger. Any such potential lawsuits could prevent or delay the closing and/or result in substantial costs to us. The outcome of any such actions would be uncertain and may create uncertainty relating to the Merger and may be costly and distracting to management. Further, the defense or settlement of any lawsuit or claim that remains unresolved at the time of the Merger may adversely affect our business, financial condition, results of operations and cash flows or those of the combined entity.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

On March 30, 2017, we announced that our Board of Directors approved a stock repurchase plan that permits us to repurchase an incremental $500.0 million in shares of common stock (the "March 2017 Stock Repurchase Plan"). As of October 1, 2023, we have repurchased 8,071,000 shares of common stock at a cumulative cost of approximately $365.1 million and an average cost per share of $45.24 under our approved stock repurchase program, leaving approximately $134.9 million available for permitted repurchases.

Subsequent Events [Abstract]
Subsequent Event	Subsequent EventOn November 2, 2023, we announced that we entered into a definitive Merger agreement to combine with Cedar Fair L.P. (“Cedar Fair”) (NYSE: FUN). Subject to the terms and conditions set forth in the Merger agreement, each issued and outstanding common share of Six Flags will be converted into the right to receive 0.58 shares of common stock of the new combined entity (subject to certain exceptions and as the same may be adjusted). Following the close of the transaction, holders of Six Flags common stock will own approximately 48.8% of the outstanding shares of the combined company, and the holders of units of Cedar Fair limited partnership interest will own approximately 51.2% of the outstanding shares of the combined company. One business day prior to the close of the transaction, Six Flags will declare a special cash dividend composed of: (i) a fixed amount of $1.00 per outstanding Six Flags share, totaling approximately $85 million in the aggregate, plus, (ii) an amount per outstanding Six Flags share equal to (a) the aggregate per unit distributions declared or paid by Cedar Fair to unitholders with a record date following today’s date and prior to the close of the transaction, multiplied by (b) the Six Flags Exchange Ratio, which special dividend will be payable to Six Flags shareholders of record as of one business day prior to the close of the transaction, contingent on the closing of the transaction. The Merger is expected to close in the first half of 2024, following receipt of Six Flags' stockholder approval, regulatory approvals, and satisfaction of other customary closing conditions.

General - Basis of Presentation (Policies)	9 Months Ended
General - Basis of Presentation (Policies)	Oct. 01, 2023
Accounting Policies [Abstract]
Consolidated U.S. GAAP Presentation	Consolidated U.S. GAAP Presentation Our accounting policies reflect industry practices and conform to U.S. GAAP. The unaudited condensed consolidated financial statements include our accounts and the accounts of our wholly owned subsidiaries. We also consolidate the partnerships that own Six Flags Over Texas ("SFOT") and Six Flags Over Georgia (including Six Flags White Water Atlanta) ("SFOG", and together with SFOT, the "Partnership Parks") in our unaudited condensed consolidated financial statements, as we have determined that we have the power to direct the activities of the Partnership Parks that most significantly impact their economic performance and we have the obligation to absorb losses and receive benefits from the Partnership Parks that can be potentially significant to these entities. The equity interests owned by non-affiliated parties in the Partnership Parks are reflected in the accompanying unaudited condensed consolidated balance sheets as redeemable noncontrolling interests.
Income Taxes	Income TaxesWe recorded a valuation allowance of $99.4 million, $96.0 million and $109.0 million as of October 1, 2023, January 1, 2023, and October 2, 2022, respectively, due to uncertainties related to our ability to use some of our deferred tax assets, primarily consisting of certain state net operating loss and other tax carryforwards, before they expire. The valuation allowance is based on our estimates of taxable income by jurisdiction in which we operate and the period over which our deferred tax assets are recoverable. Our projected taxable income over the foreseeable future indicates we will be able to use all of our federal net operating loss carryforwards before they expire. We classify interest and penalties attributable to income taxes as part of income tax expense. As of October 1, 2023, January 1, 2023, and October 2, 2022, we had no recorded amounts for accrued interest or penalties.
Goodwill and Intangibles	Goodwill and IntangiblesAs of October 1, 2023, the fair value of our single reporting unit exceeded our carrying amount. We have one reporting unit at the same level for which Holdings common stock is traded and we believe our market capitalization is the best indicator of our reporting unit’s fair value. As of October 1, 2023, we did not identify any triggering events that would require a full quantitative analysis to be performed.
Long-Lived Assets	Long-Lived AssetsWe review long-lived assets, including finite-lived intangible assets subject to amortization, for impairment upon the occurrence of events or changes in circumstances that would indicate that the carrying value of the asset or group of assets may not be recoverable, “triggering event(s)”. Recoverability of assets to be held and used is measured by comparing the carrying amount of the asset or group of assets to the projected future net cash flows expected to be generated by the asset or group of assets. If such assets are not determined to be fully recoverable, any impairment to be recognized is measured by the amount by which the carrying amount of the asset or group of assets exceeds its respective estimated fair value. Assets held-for-sale are reported at the lower of the carrying amount or fair value less costs to sell. As of October 1, 2023, we did not identify any triggering events that would require a quantitative analysis.
Stock Benefit Plans	Stock Benefit Plans Pursuant to the Six Flags Entertainment Corporation Long-Term Incentive Plan (the "Long-Term Incentive Plan"), we may grant stock options, stock appreciation rights, restricted stock, restricted stock units, unrestricted stock, deferred stock units, performance stock units, performance and cash-settled awards and dividend equivalent rights ("DERs") to select employees, officers, directors and consultants. Periodically, we grant performance stock units to key employees. These awards vest based on attainment of specific performance targets most often related to Adjusted EBITDA or revenue over a defined period. As of October 1, 2023, we have not determined that it is probable that we will achieve any of the performance targets associated with our outstanding performance units, and we have therefore not recognized any expense for these awards.
Accounts Receivable, Net	Accounts Receivable, NetAccounts receivable are reported at net realizable value and consist primarily of amounts due from guests for the sale of group outings and multi-use admission products that allow for payment plans, such as season passes, annual passes, memberships and our Six Flags Plus pass. We are not exposed to a significant concentration of credit risk; however, based on the age of receivables, our historical experience and other factors and assumptions we believe to be customary and reasonable, we record an allowance for doubtful accounts. As of October 1, 2023, January 1, 2023, and October 2, 2022, we have recorded an allowance for doubtful accounts of $10.1 million, $4.1 million, and $7.6 million, respectively, which is primarily comprised of estimated payment defaults under our Six Flags Plus pass and other multi-use admission products that allow for payment plans. To the extent that payments for products for which an allowance for doubtful accounts is established have not been recognized in revenue, the allowance recorded is offset with a corresponding reduction in deferred revenue.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting PronouncementsIn March 2020, FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“Update 2020-04”), which provides optional expedients and exceptions for applying U.S. GAAP principles to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in Update 2020-04 apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected optional expedients for and that are retained through the end of the hedging relationship. The provisions in Update 2020-04 are effective upon issuance and can be applied prospectively through December 31, 2022. As of October 1, 2023, we no longer have any debt instruments that contain LIBOR as a reference rate. Our adoption of Update 2020-04 did not have any effect on our condensed consolidated financial statements.
