Exhibit 99.1

SiriusXM Announces Retention of Financial and Legal Advisors

by the Special Committee of its Board of Directors

Sirius XM and Liberty Media Defer Balance of Share Repurchase to April 2014

NEW YORK –January 24, 2014 – SiriusXM announced today that the Special Committee of its Board of Directors has retained Evercore Group L.L.C. to act as its financial advisor and Weil, Gotshal & Manges LLP to act as its legal counsel to assist and advise the Special Committee in connection with its evaluation of Liberty Media Corporation’s proposal to acquire all of the outstanding shares of common stock of SiriusXM not owned by Liberty Media. SiriusXM formed the Special Committee, comprised entirely of independent directors not affiliated with Liberty Media, following SiriusXM’s receipt of Liberty Media’s proposal on January 3, 2014.

The Special Committee intends to work with its financial and legal advisors to, among other things, review and evaluate whether the Liberty Media proposal is in the best interests of SiriusXM and its stockholders, other than Liberty.

In addition, in light of SiriusXM’s receipt of Liberty Media’s proposal, the Special Committee has authorized Sirius XM to enter into an agreement with Liberty Media to defer the previously scheduled $240 million repurchase of shares of SiriusXM common stock from Liberty Media from January 27, 2014 to April 25, 2014 (the date of the final installment of share repurchases from Liberty Media pursuant to the October 9, 2013 agreement with Liberty Media, as amended). As a result of this deferral, SiriusXM will repurchase $340 million of its shares of common stock from Liberty Media on April 25, 2014 at a price of $3.66 per share.

SiriusXM cautions its stockholders and others considering trading in its common stock that no decisions have been made by the Board of Directors or the Special Committee with respect to Liberty Media’s proposal. There can be no assurance that any agreement based on Liberty Media’s proposal will be approved or recommended by the Special Committee, or that any transaction will be entered into or consummated. SiriusXM does not anticipate making any further public statements regarding these matters unless and until either it enters into a definitive agreement for a transaction or the Special Committee determines that no such transaction will be effected, or it otherwise deems further disclosure is appropriate or required by law.
