State below in reasonable detail why Form 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Six Flags Entertainment Corporation (the "Company") is filing this Notification of Late Filing on Form 12b-25 with respect to its Annual Report on Form 10-K for the fiscal year ended January 1, 2023 (the "Form 10-K"). The Company has determined that it is unable to file its Form 10-K within the prescribed time period without unreasonable effort or expense for the reasons set forth below.

***Reasons for Delay***

The Company has determined that it is unable to file the Form 10-K within the prescribed time period without unreasonable effort or expense because it requires additional time to complete its financial statement preparation and review process. As a result of the foregoing, KPMG LLP, the Company's independent registered public accounting firm, has not yet completed its audit procedures. The Company expects to file its Form 10-K on or before Friday, March 17, 2023, which is within the fifteen-calendar day extension provided by Rule 12b-25.

***Preliminary Financial Results for the Fiscal Year ended January 1, 2023***

The Company expects to report revenue of approximately $1.4 billion for the fiscal year ended January 1, 2023 compared to revenue of $1.5 billion for the fiscal year ended January 2, 2022. The Company expects to report net income for the fiscal year ended January 1, 2023 of approximately $109 million or $1.29 per diluted share compared to net income of $130 million, or $1.50 per diluted share for the fiscal year ended January 2, 2022. The foregoing figures are preliminary and unaudited and are prepared in accordance with U.S. generally accepted accounting principles.

The Company does not expect any changes to the preliminary unaudited financial results reported above or to the preliminary financial results previously reporting in its earnings release furnished as Exhibit 99.1 to the Company's Current Report on Form 8-K filed on March 2, 2023, however results may be subject to change after the completion of year-end reviews and the completion of the audit.

***Forward-Looking Statements***

This filing contains a number of forward-looking statements. Words such as "expect," "will," "working," and variations of such words and similar future or conditional expressions are intended to identify

forward-looking statements. These forward-looking statements include, but are not limited to, statements regarding our beliefs and expectations relating to the filing of the Form 10-K and the estimated reporting of financial results. These forward-looking statements are not guarantees of future results and are subject to a number of risks and uncertainties, many of which are difficult to predict and beyond our control. Important factors that may cause actual results to differ materially from those in the forward-looking statements include, but are not limited to, a material delay in the Company's financial reporting, including the possibility that the Company will not be able to file its Form 10-K within the fifteen-day extension permitted by the rules of the U.S. Securities and Exchange Commission. The Company disclaims and does not undertake any obligation to update or revise any forward-looking statement in this report, except as required by applicable law or regulation.
