On July 1, 2024 (the “Closing Date”), Cedar Fair, L.P. (the “Partnership”) completed the previously announced merger of equals transaction contemplated by the Agreement and Plan of Merger, dated as of November 2, 2023 (the “Merger Agreement”), by and among the Partnership, Six Flags Entertainment Corporation (“Former Six Flags”), CopperSteel HoldCo, Inc. (“HoldCo”), and CopperSteel Merger Sub, LLC (“Copper Merger Sub”). Pursuant to the Merger Agreement, (i) Copper Merger Sub was merged with and into the Partnership (the “Cedar Fair First Merger”), with the Partnership continuing as the surviving entity (the “Cedar Fair Surviving Entity”) and a direct subsidiary of HoldCo, (ii) the Cedar Fair Surviving Entity was subsequently merged with and into HoldCo (the “Cedar Fair Second Merger” and together with the Cedar Fair First Merger, the “Cedar Fair Mergers”), with HoldCo continuing as the surviving corporation, and (iii) Former Six Flags merged with and into HoldCo (the “Six Flags Merger” and together with the Cedar Fair Mergers, the “Mergers”), with HoldCo continuing as the surviving corporation. Upon the consummation of the Mergers, the separate legal existences of Copper Merger Sub, the Partnership and Former Six Flags ceased, and HoldCo changed its name to “Six Flags Entertainment Corporation.” Capitalized terms used herein but not otherwise defined have the meaning set forth in the Merger Agreement.

Upon completion of the Mergers, subject to certain exceptions, (i) each issued and outstanding unit of limited partnership interest in the Partnership, including limited partnership interests underlying depositary units representing limited partnership interests on deposit with the Depositary pursuant to the Deposit Agreement (each, a “Cedar Fair Unit” and collectively, the “Cedar Fair Units”) (excluding (a) units held in the treasury of the Partnership or owned by Cedar Fair Management, Inc., the general partner of the Partnership (the “General Partner”) and (b) any restricted Cedar Fair Units subject to time or service-based vesting conditions, granted under the Cedar Fair 2016 Omnibus Incentive Plan (which equity awards were converted into a number of restricted shares of HoldCo Common Stock based on the Cedar Fair Exchange Ratio, as further described below)), was converted into the right to receive one (1) share of common stock, par value $0.01 per share, of HoldCo (the “HoldCo Common Stock”) (the “Cedar Fair Exchange Ratio”), together with cash in lieu of fractional shares of HoldCo Common Stock, without interest and (ii) each issued and outstanding share of common stock, par value $0.025 per share of Former Six Flags (the “Former Six Flags Common Stock”) (excluding (a) any shares of Former Six Flags Common Stock held in treasury of Former Six Flags and (b) any restricted Former Six Flags Common Stock subject to vesting or other transfer restrictions, granted under the Former Six Flags Long Term Incentive Plan (which equity awards were converted into a number of restricted shares of HoldCo Common Stock based on the Former Six Flags Exchange Ratio, as further described below)) was converted into the right to receive 0.5800 shares of HoldCo Common Stock (the “Former Six Flags Exchange Ratio”), together with cash in lieu of fractional shares of HoldCo Common Stock, without interest.

As previously announced by Former Six Flags, on June 18, 2024, Former Six Flags declared a special dividend (the “Special Dividend”), payable to holders of record of Former Six Flags Common Stock as of the close of business one Business Day prior to the Closing Date, June 28, 2024, who hold their shares through the Closing Date, with a per share amount of $1.53, which is equal to (a) $1.00 plus (b) the product (rounded up to the nearest whole cent) of (i) the Former Six Flags Exchange Ratio and (ii) the aggregate amount of distributions per unit declared or paid by the Partnership with respect to a Cedar Fair Unit with a record date following November 2, 2023 and prior to the Closing Date, after giving effect to appropriate adjustments to reflect the Mergers, which distributions per Cedar Fair Unit were $0.90 in the aggregate. The payment of the Special Dividend is expected to be completed on or about July 8, 2024.

At the time the Cedar Fair First Merger became effective (the “Cedar Fair First Merger Effective Time”), each outstanding Partnership equity award (other than deferred Cedar Fair Units held by non-employee members of the board of directors of the General Partner) was converted into a corresponding award relating to shares of HoldCo Common Stock, with the number of shares of HoldCo Common Stock subject to such converted award based on the Cedar Fair Exchange Ratio. The converted Partnership equity awards remain outstanding and subject to the same terms and conditions applied under applicable plans and award agreements immediately prior to the Cedar Fair First Merger Effective Time, including vesting protections for qualifying terminations that occur within a period of 24 months following the Closing Date. Performance-based Partnership equity awards were converted based on the higher of target performance and actual performance or, in the case of awards related to any performance period that was not in progress as of the Closing Date, were converted based on target performance and will not be subject to future performance-based vesting conditions (but will remain subject to service-based vesting conditions). Any outstanding deferred Cedar Fair Units were settled at the First Cedar Fair Merger Effective Time in either cash or shares of HoldCo Common Stock in accordance with such terms.

The issued and outstanding Special LP Interests immediately prior to the Cedar Fair First Merger Effective Time were converted into the right to receive $5,290,500 in the aggregate (less any Special LP Interest amount paid prior to the Closing Date), without interest, with such aggregate amount payable to such holders thereof pro rata based on the holders’ relative capital accounts, and were automatically canceled, retired and cease to exist.

On the Closing Date, each Former Six Flags equity award was converted into a corresponding award relating to shares of HoldCo Common Stock, with the number of shares of HoldCo Common Stock subject to such converted award based on the Former Six Flags Exchange Ratio. The converted Former Six Flags equity awards remain outstanding and subject to the same terms and conditions as applied under the applicable plans and award agreements immediately prior to the Closing Date (except that (i) performance-based awards were converted based on the greater of target and actual performance and will not be subject to future performance-based vesting conditions (but will remain subject to service-based vesting conditions) and (ii) all converted awards are subject to vesting protections for qualifying terminations that occur within a period of 24 months following the Closing Date). Any outstanding Former Six Flags deferred share units were settled on the Closing Date in shares of HoldCo Common Stock based on the Former Six Flags Exchange Ratio. All Former Six Flags equity awards are eligible for payment of the Special Dividend; provided, that such amount will not be paid until such time as the underlying Former Six Flags equity award, as converted, becomes vested or settled pursuant to its terms (if at all).

The issuance of shares of HoldCo Common Stock in connection with the Mergers, as described above, was registered under the Securities Act of 1933, as amended, pursuant to a Registration Statement on Form S–4 (File No. 333-276255), filed by HoldCo with the Securities and Exchange Commission (the “SEC”) and declared effective on January 31, 2024.
