Explanation of Responses:

( 1 )On June 2, 2025, Discovery Lightning Investments Ltd. ("DLI") entered into an agreement with MHR Capital Partners Master Account LP and MHR Capital Partners (100) LP (together, the "MHR Entities"), pursuant to which the MHR Entities agreed to purchase 353,334 common shares, no par value ("Common Shares"), of Starz Entertainment Corp. (the "Issuer") from DLI in a private transaction for aggregate cash consideration of $5,000,000. Following the consummation of such transaction on June 3, 2025, DLI ceased to own any Common Shares. ( 2 )The shares are held directly by DLI. Because DLI is an indirect wholly-owned subsidiary of Warner Bros. Discovery, Inc. ("WBD"), WBD may be deemed to beneficially own the reported securities. WBD expressly disclaims beneficial ownership of the reported securities, except to the extent of its pecuniary interest therein.

Remarks: Prior to the consummation of the transaction described in this filing, as a result of certain agreements among the Reporting Persons, the Issuer and certain other shareholders of the Issuer, the Reporting Persons may have been deemed members of a "group", within the meaning of Rule 13d-5(b)(1) under the Securities Exchange Act of 1934, as amended (the "Act"), with such other shareholders, that beneficially owned more than 10% of the Common Shares of the Issuer. These agreements are described in, and filed as exhibits to, the Issuer's Current Report on Form 8-K filed with the Securities Exchange Commission on May 7, 2025. This filing is being made as a precautionary matter and shall not be deemed an admission that any of the Reporting Persons was a member of a group or subject to the reporting requirements of Section 16 of the Act. Following the consummation of the transaction described in this filing, the Reporting Persons beneficially own no Common Shares.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).

** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
