Concurrently with the delisting of the shares of Liberty SiriusXM Common Stock, Liberty Media expects that the shares of common stock of SplitCo will begin trading on Nasdaq under the ticker symbol “SIRI” as of September 10, 2024.

Item 5.07. Submission of Matters to Vote of Security Holders.

At Liberty Media’s special meeting of the holders of LSXMA and LSXMB held on August 23, 2024 (the “Special Meeting”), the following proposals were considered and acted upon by the holders of LSXMA and LSXMB: (1) a proposal (the “Split-Off Proposal”) to approve the redemption by Liberty Media of each outstanding share of LSXMA, LSXMB and LSXMK in exchange for a number of shares of common stock of SplitCo, equal to the Exchange Ratio (as defined in that certain Reorganization Agreement, dated as of December 11, 2023, by and among Liberty Media, SplitCo and Sirius XM Holdings Inc., a Delaware corporation (“Sirius XM”), as amended by that certain First Amendment to the Reorganization Agreement, dated as of June 16, 2024, by and among Liberty Media, SplitCo and Sirius XM (collectively and as amended from time to time, the “Reorganization Agreement”)); and (2) a proposal (the “Adjournment Proposal”) to approve the adjournment of the Special Meeting by Liberty Media from time to time to solicit additional proxies in favor of the Split-Off Proposal if there are insufficient votes at the time of such adjournment to approve the Split-Off Proposal or if otherwise determined by the chairperson of the Special Meeting to be necessary or appropriate. The number of votes cast for or against, as well as the number of abstentions and broker non-votes as to each proposal, are set forth below.
