This Amendment No. 1 on Form 8-K/A (the "Amendment") amends the Current Report on Form 8-K of Six Flags Entertainment Corporation (the "Company"), as initially filed with the Securities and Exchange Commission on June 27, 2025 (the "Original Form 8-K"). The Original Form 8-K reported the final voting results of the Company's annual meeting of stockholders held on June 25, 2025 (the "2025 Annual Meeting"). The purpose of this Amendment is to disclose the Company's decision regarding how frequently it will conduct future stockholder advisory votes to approve the compensation of the Company's named executive officers ("say-on-pay"). No other changes have been made to the Original Form 8-K.

**Item 5.07.&nbsp;&nbsp;&nbsp;&nbsp;Submission of Matters to a Vote of Security Holders.**

As previously reported in the Original Form 8-K, in a non-binding advisory vote on the frequency of future say-on-pay votes held at the 2025 Annual Meeting, 77,006,513 shares voted for one year, 268,913 shares voted for two years, 317,291 shares voted for three years, 189,554 shares abstained, and there were 12,479,799 broker non-votes. In light of the results of the advisory vote on the frequency of say-on-pay votes, the Company's Board of Directors determined the Company will continue to hold an advisory say-on-pay vote annually until the occurrence of the next advisory vote on the frequency of say-on-pay votes. The next advisory vote regarding the frequency of say-on-pay votes is expected to occur at the Company's annual meeting of stockholders in 2031.
