On June 16, 2024, Sirius XM Holdings Inc. (“SiriusXM”) entered into amendments (the “Amendments”) to (i) the Reorganization Agreement (the “Reorganization Agreement”), dated as of December 11, 2023, with Liberty Media Corporation, a Delaware corporation (“Liberty” or “Liberty Media”) and Liberty Sirius XM Holdings Inc., a Delaware corporation and a wholly owned subsidiary of Liberty (“New Sirius”), and (ii) the Agreement and Plan of Merger (the “Merger Agreement”), dated as of December 11, 2023, with Liberty, New Sirius and Radio Merger Sub, LLC, a Delaware limited liability company and a wholly owned subsidiary of New Sirius (“Merger Sub”), relating to the split-off of New Sirius, which will own all of the assets and liabilities attributed to the Liberty SiriusXM Group, from Liberty (the “Split-Off”) and, following the Split-Off, the combination of New Sirius and SiriusXM through the merger of Merger Sub with SiriusXM, with SiriusXM becoming a wholly owned subsidiary of New Sirius (the “Merger” and, together with the Split-Off, the “Transactions”).

The Amendments, among other things, ratably adjust the exchange ratios in each of the Reorganization Agreement and the Merger Agreement in connection with the Transactions to reduce the total number of outstanding shares of New Sirius common stock, par value $0.001 per share (“New Sirius Common Stock”), following the consummation of the Transactions. The revised exchange ratio in the Reorganization Agreement reduces by 90% the number of shares of New Sirius Common Stock that otherwise would have been issued to holders of Liberty SiriusXM Common Stock (as defined below). As a result of the revised exchange ratio under the Merger Agreement, each existing holder of SiriusXM common stock, par value $0.001 per share (“SiriusXM Common Stock”), will receive 1 share in New Sirius for every 10 shares of SiriusXM Common Stock it holds as of immediately prior to the consummation of the Transactions, with cash paid in lieu of fractional shares.

These changes to the exchange ratios affect SiriusXM stockholders and holders of shares of Liberty Media’s Series A Liberty SiriusXM common stock, par value $0.01 per share (“LSXMA”), Liberty Media’s Series B Liberty SiriusXM common stock, par value $0.01 per share (“LSXMB”), and Liberty Media’s Series C Liberty SiriusXM common stock, par value $0.01 per share (“LSXMK” and, together with LSXMA and LSXMB, the “Liberty SiriusXM Common Stock”), uniformly and will not alter any such stockholder’s percentage interest in the outstanding shares of New Sirius Common Stock as of immediately following the consummation of the Transactions, except to the extent that it results in some stockholders receiving cash in lieu of owning a fractional share of New Sirius Common Stock as described above. These changes to the exchange ratios are intended to preserve the economics of the Transactions announced in December 2023, while reducing the number of shares of New Sirius Common Stock that would be outstanding immediately after the closing of the Transactions. In addition, these changes are expected to more closely align the nominal share price of New Sirius Common Stock immediately after the closing of the Transactions with the price of the shares of Liberty SiriusXM Common Stock being redeemed in the Split-Off, and increase the nominal price per share of New Sirius Common Stock, which is designed to help improve trading dynamics in the stock and potentially increase its attractiveness to investors.

In addition, in order to facilitate the Transactions, Sirius XM Radio Inc., a Delaware corporation, intends to convert under Delaware state law to a Delaware limited liability company prior to the closing of the Transaction. The conversion of Sirius XM Radio Inc. is conditioned upon the approval of the conversion under the Communications Act of 1934.

The parties are working diligently to complete the Transactions as soon as practicable. We expect the closing to occur in the third quarter of 2024.

The Amendments have been approved by Liberty’s Board of Directors, the SiriusXM Special Committee and SiriusXM’s Board of Directors. Liberty’s Board of Directors has recommended that holders of shares of LSXMA and LSXMB vote in favor of the Split-Off, as it has been amended. Additionally, in connection with the execution of the Amendments, Liberty Radio, LLC, a wholly owned subsidiary of Liberty Media that holds a majority of the outstanding shares of SiriusXM common stock, in its capacity as stockholder of SiriusXM, has delivered to SiriusXM a written consent pursuant to Section 228 of the General Corporation Law of the State of Delaware, approving and adopting the Amendments. As a result, no meeting of the stockholders of SiriusXM will be held in connection with the Amendments.

The foregoing description of the Amendments does not purport to be complete and is qualified in its entirety by the full text of the Amendments, copies of which are filed herewith as Exhibit 10.1 and Exhibit 2.1, respectively, and the terms of which are incorporated by reference herein. Copies of the Reorganization Agreement and the Merger Agreement were filed as Exhibits to the Current Report on Form 8-K filed by SiriusXM on December 13, 2023.
