Item 1.01.  Entry into a Material Definitive Agreement.

On December 11, 2023, Liberty Media Corporation, a Delaware corporation (“Liberty Media”), entered into definitive agreements whereby, subject to the terms thereof, Liberty Sirius XM Holdings Inc., a Delaware corporation and a wholly owned subsidiary of Liberty Media (“New Sirius”), would split-off from Liberty Media, and Radio Merger Sub, LLC, a Delaware limited liability company and a wholly owned subsidiary of New Sirius (“Merger Sub”), would combine with Sirius XM Holdings Inc., a Delaware corporation (“SiriusXM”), to create a new public company, which will be renamed “SiriusXM Holdings Inc.”. The transactions would be effectuated by means of a redemptive split-off of New Sirius (the “Split-Off), which will own all of the assets and liabilities attributed to the Liberty SiriusXM Group, followed by New Sirius combining with 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”).

To effect the Transactions, on December 11, 2023, Liberty Media entered into (i) a Reorganization Agreement (the “Reorganization Agreement”) with SiriusXM and New Sirius, and (ii) an Agreement and Plan of Merger (the “Merger Agreement”) with New Sirius, SiriusXM and Merger Sub.

In connection with the Merger Agreement and the Reorganization Agreement, on December 11, 2023, certain trusts related to Dr. John C. Malone (collectively, the “Malone Stockholders”) entered into a voting agreement (the “Voting Agreement”) with Liberty Media, SiriusXM and New Sirius, pursuant to which, among other things, the Malone Stockholders have agreed, subject to the terms of the Voting Agreement, to vote their respective shares of Liberty Media’s Series A Liberty SiriusXM common stock, par value $0.01 per share (“LSXMA”), and Liberty Media’s Series B Liberty SiriusXM common stock, par value $0.01 per share (“LSXMB”), in favor of the Split-Off.

The terms of the definitive agreements entered into in connection with the Split-Off and the Merger are summarized below.

Reorganization Agreement

The Reorganization Agreement governs, among other things, the terms and conditions of the Split-Off. The Split-Off would be accomplished by a redemption by Liberty Media of each outstanding share of LSXMA, LSXMB and Liberty Media’s Series C Liberty SiriusXM common stock, par value $0.01 per share (“LSXMK” and, together with LSXMA and LSXMB, “Liberty SiriusXM Common Stock”), in exchange for a number of shares of New Sirius common stock, par value $0.001 per share (“New Sirius Common Stock”), equal to the Exchange Ratio (as defined in the Reorganization Agreement and further described below) (such redemption and exchange, the “Redemption”), with cash paid in lieu of any fractional shares of New Sirius Common Stock. At the time of the Split-Off, New Sirius will hold all of the businesses, assets and liabilities attributed to the Liberty SiriusXM Group, including (1) all of Liberty Media’s direct and indirect interest in SiriusXM (which currently represents approximately 84% of the outstanding shares of common stock, par value $0.001 per share, of SiriusXM (“SiriusXM Common Stock”)), (2) corporate cash, (3) Liberty Media’s 3.75% Convertible Senior Notes due 2028, (4) Liberty Media’s 2.75% Exchangeable Senior Debentures due 2049 and (5) a margin loan obligation (the “Margin Loan”) incurred by Liberty Media’s wholly owned special purpose subsidiary, which is secured by shares of SiriusXM Common Stock (collectively, the “New Sirius Assets and Liabilities”).

As a result of the Split-Off, New Sirius would become an independent, publicly traded company with one class of common stock outstanding immediately following the Split-Off.

Equity Awards. In connection with the Split-Off, (i) stock options relating to Liberty SiriusXM Common Stock that are outstanding immediately prior to the Split-Off would accelerate and become fully vested and holders thereof will receive stock options relating to New Sirius Common Stock, with the number of shares underlying such stock options and the exercise prices thereof adjusted based on the Exchange Ratio, and (ii) restricted stock awards and restricted stock units relating to Liberty SiriusXM Common Stock will accelerate and become fully vested prior to the Split-Off and will be treated as outstanding shares of Liberty SiriusXM Common Stock in the Redemption. The New Sirius options will be governed by the terms of the Liberty SiriusXM Transitional Stock Adjustment Plan, which was approved in connection with the Reorganization Agreement. Additionally, the Sirius XM 2024 Long-Term Incentive Plan, which was approved in connection with the Transactions, will permit equity awards with respect to 350 million shares of New Sirius Common Stock to be granted to eligible employees and other service providers of New Sirius following the Merger.

Conditions. The closing of the Split-Off is conditioned on, among other things, the satisfaction (or, if permissible, waiver) of the conditions to the Merger in the Merger Agreement (subject to certain limited exceptions).

Exchange Ratio. Prior to the closing of the Split-Off and pursuant to the Reorganization Agreement, the Exchange Ratio will be calculated based on (i) the number of shares of SiriusXM Common Stock held by Liberty Media immediately prior to the Split-Off reduced by a net liabilities share adjustment, divided by (ii) the number of adjusted fully diluted shares of Liberty SiriusXM Common Stock as of the date that is seven business days prior to the date of closing of the Redemption (the “Measurement Date”):

Ancillary Agreements. At or prior to the closing of the Split-Off, Liberty Media and New Sirius will enter into other agreements, including, but not limited to, a tax sharing agreement that will govern Liberty Media’s and New Sirius’s respective rights, responsibilities and obligations with respect to certain taxes and tax benefits, the filing of tax returns, the control of audits and other tax matters (the “Tax Sharing Agreement”), as well as certain other restructuring agreements related to the Split-Off. Further information regarding these agreements will be included in New Sirius’ registration statement on Form S-4.

Cross-Indemnities. From and after the Split-Off, New Sirius has agreed to indemnify Liberty Media, its subsidiaries (excluding New Sirius and its subsidiaries) and their respective representatives from losses sustained in connection with, among others, the New Sirius Assets and Liabilities and the conduct of the businesses of New Sirius. From and after the Split-Off, Liberty Media has agreed to indemnify New Sirius, its subsidiaries and their respective representatives from losses sustained in connection with, among others, the assets, liabilities and businesses being retained by Liberty Media in connection with the Split-Off.

The foregoing description of the Reorganization Agreement does not purport to be complete and is qualified in its entirety by the full text of the Reorganization Agreement, a copy of which is filed herewith as Exhibit 10.1 and the terms of which are incorporated by reference herein.

Agreement and Plan of Merger

Pursuant to the Merger Agreement, the Merger would be consummated substantially concurrently with, but following, the Split-Off. Upon completion of the Split-Off and the Merger, New Sirius would own and hold, directly or indirectly, the New Sirius Assets and Liabilities (other than liabilities satisfied in connection with the Merger), and SiriusXM would become a wholly owned subsidiary of New Sirius.

Effect on SiriusXM Common Stock. In the Merger Agreement, each share of SiriusXM Common Stock issued and outstanding immediately prior to the effective time of the Merger (the “Effective Time”) (other than shares owned by New Sirius and its subsidiaries) would be converted into the right to receive one share of New Sirius Common Stock (the “Merger Consideration”).

Effect on SiriusXM Equity Awards. In connection with the Merger, (i) each stock option relating to SiriusXM Common Stock (a “SiriusXM option”) that is outstanding and unexercised immediately prior to the Effective Time would be converted into a stock option relating to New Sirius Common Stock, and such converted option will have the same terms (including the number of shares subject to and the exercise price and vesting requirements) as those of the corresponding SiriusXM option immediately prior to the Effective Time, and (ii) each restricted stock unit relating to SiriusXM Common Stock (a “SiriusXM RSU”) that is outstanding immediately prior to the Effective Time would be converted into a restricted stock unit relating to New Sirius Common Stock, with such converted restricted stock unit having the same terms (including the number of shares subject to and vesting requirements) as those of the corresponding SiriusXM RSU immediately prior to the Effective Time.

Closing Conditions. The closing of the Merger is subject to certain customary conditions, including: (i) the approval of the Redemption by the holders of at least a majority of the aggregate voting power of the shares of LSXMA and shares of LSXMB, voting together as a separate class, that are present (in person or by proxy) and entitled to vote at a meeting of the holders of LSXMA and LSXMB, or any adjournment or postponement thereof, (ii) the completion of the Split-Off, (iii) any required approvals under applicable U.S. antitrust laws, (iv) any required approvals under applicable U.S. communications laws, (v) the absence of any law or order prohibiting the consummation of the Transactions, (vi) an effective registration statement on Form S-4 with respect to shares of New Sirius Common Stock to be issued in the Transactions and (vii) Nasdaq listing approval of the shares of New Sirius Common Stock to be issued in the Transactions.

Tax Opinions. In addition, the obligation of SiriusXM and Liberty Media to complete the Merger is conditioned on each party’s receipt of a customary tax opinion regarding the intended tax-free status of the Merger. Liberty Media’s obligation to complete the Merger is further conditioned on Liberty Media’s receipt of customary tax opinions regarding the intended tax-free status of the Contribution (as defined in the Reorganization Agreement) and the Redemption and the non-impact of the Contribution, Redemption and Merger on Liberty Media’s prior split-off of its former wholly owned subsidiary, Atlanta Braves Holdings, Inc.

SiriusXM Merger Approval. In connection with the execution of the Merger Agreement, 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 a stockholder of SiriusXM, has delivered to SiriusXM a written consent pursuant to Section 228 of the General Corporation Law of the State of Delaware, adopting the Merger Agreement and approving the transactions contemplated by the Merger Agreement, including the Merger. As a result, no meeting of the stockholders of SiriusXM is expected to be held in connection with the Transactions.

Representations, Warranties and Covenants. The Merger Agreement includes certain customary representations, warranties and covenants of Liberty Media, New Sirius, Merger Sub and SiriusXM. In addition, each of Liberty Media and SiriusXM has agreed to customary “no-shop” restrictions prohibiting each party from soliciting alternative proposals from or participating in any discussions or negotiations with, third parties regarding alternative acquisition proposals. The Board of Directors of Liberty Media (the “Liberty Board”) has agreed to recommend that holders of shares of LSXMA and LSXMB vote in favor of the approval of the Redemption, subject to the right to change its recommendation if the Liberty Board determines, in good faith, after consulting with outside legal counsel, that failure to make such change would result in a violation of the Liberty Board’s fiduciary duties under applicable law. In the event that the Liberty Board changes its recommendation, SiriusXM has the right to either (i) require Liberty Media to hold a stockholder vote on the Redemption or (ii) terminate the Merger Agreement, subject to the payment by Liberty Media to SiriusXM of a termination fee equal to $450 million.

Termination. The Merger Agreement, in addition to certain customary termination provisions and the right of SiriusXM to terminate following a change of recommendation of the Liberty Board as discussed above, provides that Liberty Media or SiriusXM may terminate the Merger Agreement, subject to certain limitations, if (i) the Merger has not been consummated by November 15, 2024 or (ii) the approval of the requisite holders of shares of LSXMA and LSXMB is not obtained at a meeting thereof called for the purpose of approving the Redemption.

Tax Sharing. Pursuant to the Merger Agreement, at the Effective Time, all of Liberty Media’s and SiriusXM’s rights and obligations under the existing tax sharing agreement between Liberty Media and SiriusXM will be terminated, and, from and after the Effective Time, Liberty Media, New Sirius and SiriusXM’s rights and obligations with respect to taxes and tax matters will be governed by the Tax Sharing Agreement.

New Sirius Management. At the Effective Time, the board of directors of New Sirius (the “New Sirius Board”) will consist of a total of nine directors and be classified and divided into three classes, designated Class I, Class II and Class III, with each class initially consisting of three directors. Liberty Media will designate five individuals (the “Liberty Media Designees”), including Gregory B. Maffei and four directors who will be determined at a later date (subject to three of such four director designees satisfying certain independence requirements). SiriusXM will designate four individuals (the “SiriusXM Designees”), including Jennifer Witz and three directors who will be determined at a later date (subject to such three director designees satisfying certain independence requirements). In connection with the foregoing appointments, (i) three of the SiriusXM Designees will be designated as the initial Class I directors for a term expiring at the first annual meeting of stockholders of New Sirius held after the Effective Time, (ii) the remaining SiriusXM Designee and two Liberty Media Designees will be designated as the initial Class II directors for a term expiring at the second annual meeting of stockholders of New Sirius held after the Effective Time, and (iii) Gregory B. Maffei and the two remaining Liberty Media Designees will be designated as the initial Class III directors for a term expiring at the third annual meeting of stockholders of New Sirius held after the Effective Time. Following the third annual meeting held after the Effective Time, the New Sirius Board will cease to be classified, and all directors thereafter elected will serve for a term expiring at the subsequent annual meeting. The officers of SiriusXM at the Effective Time will serve in the same capacity at New Sirius.

Pro Forma Ownership. As a result of the Transactions, based on an estimated number of 3,838.9 million shares of SiriusXM Common Stock outstanding and 326.6 million shares of Liberty SiriusXM Common Stock outstanding, Liberty Media estimates that the former holders of Liberty SiriusXM Common Stock will own approximately 81% of New Sirius, with the former holders of SiriusXM Common Stock, other than Liberty Media and its subsidiaries, owning the remaining approximately 19% of New Sirius.

Approval and Recommendation. The Liberty Board has approved the Merger Agreement, the Reorganization Agreement and the transactions contemplated thereby and recommended that the holders of shares of LSXMA and LSXMB approve the Redemption and the transactions contemplated thereby, subject to certain exceptions set forth in the Merger Agreement.

The foregoing description of the Merger Agreement does not purport to be complete and is qualified in its entirety by the full text of the Merger Agreement, a copy of which is filed herewith as Exhibit 2.1 and the terms of which are incorporated by reference herein.

Voting Agreement

The Voting Agreement provides that, among other things, the Malone Stockholders have agreed to vote their respective shares of LSXMA and LSXMB, representing approximately 48% of the total voting power of the issued and outstanding shares of LSXMA and LSXMB in the aggregate, in favor of the Split-Off and the transactions contemplated thereby, except that they will be obligated to vote shares representing approximately 33.37% in favor of thereof in the event that the Liberty Board changes its recommendation and SiriusXM elects not to terminate the Merger Agreement.

In addition, subject to certain conditions, the Malone Stockholders have agreed to vote their respective shares of LSXMA and LSXMB subject to the Voting Agreement against any SplitCo Takeover Proposal (as defined in the Merger Agreement) and certain other matters. The Voting Agreement will automatically terminate upon, among other events, the termination of the Merger Agreement or the Reorganization Agreement in accordance with their respective terms. Under the Voting Agreement, each of SiriusXM and New Sirius, jointly and severally, has agreed to indemnify each Malone Stockholder for certain losses incurred in connection with or arising out of the Voting Agreement or the performance of such Malone Stockholder’s obligations thereunder, including, subject to certain conditions, reasonable fees and expenses of such Malone Stockholder incurred in the defense of any such claim brought by a third party. In addition, SiriusXM and New Sirius have agreed to pay up to $150,000 in the aggregate of reasonable out-of-pocket costs and expenses incurred by the Malone Stockholders in connection with the preparation, negotiation, execution and delivery of the Voting Agreement.

The foregoing description of the Voting Agreement does not purport to be complete and is qualified in its entirety by the full text of the Voting Agreement, a copy of which is filed herewith as Exhibit 10.2 and the terms of which are incorporated by reference herein.
