Subsequent Events	Subsequent Events 5.500% Senior Notes Exchange. On May 8, 2024, an indirect, wholly-owned subsidiary of the Company issued $389.9 million aggregate principal amount of new 5.500% senior notes due 2029 (the "New 5.500% Senior Notes"). The New 5.500% Senior Notes were exchanged by the Company for $389.9 million of the existing 5.500% Senior Notes. The New 5.500% Senior Notes initially bear interest at 5.500% annually and mature April 15, 2029, with the interest rate increasing to 6.000% and the maturity date extending to April 15, 2030 effective upon completion of the separation of the Starz Business from the Studio Business. The Company may redeem the New 5.500% Senior Notes, in whole at any time, or in part from time to time, prior to or on and after the Separation Closing Date, as defined in the indenture to the New 5.500% Senior Notes, at certain specified redemption prices set forth in the indenture to the New 5.500% Senior Notes, plus accrued and unpaid interest, if any, to, but not including, the redemption date. Business Combination Agreement. On May 13, 2024, the Company consummated the Business Combination referred to in Note 2. In connection with the closing of the Business Combination, SEAC II Corp. changed its name to “Lionsgate Studios Corp.” (referred to as “Lionsgate Studios”). Lionsgate Studios has continued the existing business operations of StudioCo, which consists of the Studio Business of Lionsgate. Lionsgate Studios became a separate publicly traded company and its common shares commenced trading on Nasdaq under the symbol “LION” on May 14, 2024. In connection with the business combination, the Company and StudioCo entered into a separation agreement pursuant to which (i) the assets and liabilities of the Company’s Studio Business (including certain subsidiaries of the Company engaged in the Studio Business) were separated from the assets and liabilities of the Company’s Starz Business (meaning substantially all of the assets and liabilities constituting the Media Networks segment, and including certain subsidiaries of the Company engaged in the Company’s Starz Business) and transferred to StudioCo such that StudioCo holds, directly or indirectly, all of the assets and liabilities of the Studio Business, and (ii) all of the Company’s equity interests in StudioCo were transferred to Studio HoldCo. As a result, approximately 87.2% of the total shares of Lionsgate Studios continue to be held by the Company, while former SEAC public shareholders and founders and common equity financing investors own approximately 12.8% of Lionsgate Studios. In addition to establishing Lionsgate Studios as a standalone publicly-traded entity, the transaction resulted in approximately $350.0 million of gross proceeds to the Company, including $274.3 million in PIPE financing. Of the total gross proceeds, approximately $330.0 million was received at or shortly after the closing of the Business Combination, with the remaining $20.0 million expected to be received shortly. The net proceeds will be used to pay down amounts outstanding under the Term Loan A and Term Loan B pursuant to the Credit Agreement. The Business Combination will be accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, Screaming Eagle will be treated as the acquired company and the Studio Business will be treated as the acquirer for financial reporting purposes. Accordingly, for accounting purposes, the financial statements of New SEAC will represent a continuation of the financial statements of the Studio Business, with the Business Combination treated as the equivalent of the Studio Business issuing stock for the historical net assets of Screaming Eagle, accompanied by a recapitalization. The net assets of Screaming Eagle will be stated at fair value, which approximates historical cost, with no goodwill or other intangible assets recorded. Operations prior to the Business Combination will be those of the Studio Business. The Studio Business will continue to be a consolidated subsidiary of the Company. See Note 2.
