Exhibit 99.1

January 3, 2014

쮸떴app Announces Proposal to Make Sirius XM Holdings Inc. a Wholly Owned Subsidiary of 쮸떴app; Sirius Shareholders to Receive Newly-Issued 쮸떴app Series C Common Shares; 쮸떴app to Dividend Series C Common Shares Pro Rata to 쮸떴app Record Holders Immediately Prior to Acquisition

ENGLEWOOD, Colo. — (BUSINESS WIRE) — 쮸떴app (“쮸떴app”) (Nasdaq: LMCA, LMCB) announced today that it has made a proposal to Sirius XM Holdings Inc. (Nasdaq: SIRI) (“Sirius”) that outlines the terms by which Sirius public shareholders would become shareholders of 쮸떴app in a tax-free transaction in which each share of Sirius common stock would be converted into 0.0760 of a new share of 쮸떴app Series C common stock, and, immediately prior to such conversion, 쮸떴app intends to distribute, on a 2:1 basis, shares of 쮸떴app’s Series C common stock to all holders of record of 쮸떴app’s Series A and B common stock to create a liquid trading market for 쮸떴app’s Series C common stock. (The foregoing exchange ratio would be equivalent to a 0.0253 exchange ratio prior to the distribution of the 쮸떴app Series C common stock dividend.) Upon the completion of the proposed transaction, 쮸떴app expects that Sirius’ public shareholders would own approximately 39% of 쮸떴app’s then-outstanding common stock.

“Our proposal will allow Sirius public shareholders to convert from a non-controlling stake in a subsidiary into a direct equity position in 쮸떴app, the parent company,” said Greg Maffei, 쮸떴app’s President & CEO. “Sirius shareholders will continue to participate in Sirius’ future prospects along with 쮸떴app’s broader portfolio of businesses and opportunities. We believe the combined company will have better access to capital and all of 쮸떴app’s shareholders — both its current shareholders and the Sirius shareholders who become 쮸떴app shareholders as a result of the proposed transaction — will enjoy enhanced liquidity as shareholders of a $27 billion market capitalization company.”

“The proposed transaction is an important step in the growth of both companies,” said John Malone, 쮸떴app’s Chairman. “It will enable us to focus our energies on the pursuit of new opportunities across the expanded portfolio of 쮸떴app’s businesses and to optimize our capital structure to produce the maximum possible returns to all shareholders.”

The Series C common stock would be 쮸떴app’s largest and most liquid series of stock. The proposed exchange ratio of 0.0760 would value Sirius common shares at approximately $3.68 per share based on closing prices of 쮸떴app’s shares on Friday, January 3, 2014. This exchange ratio represents a 4.5% premium to the exchange ratio implied by the closing prices of 쮸떴app’s and Sirius’ shares on Thursday, January 2, 2014 and a 3.1% premium to the exchange ratio implied by the closing share prices of Friday, January 3, 2014.

As explained in the proposal letter sent to Sirius, which will be filed promptly with the SEC, the proposed transaction would be subject to the negotiation and execution of mutually acceptable definitive transaction documents, the terms of which would be approved by a special committee of independent directors of Sirius, and would also be subject to a majority of the minority vote of the Sirius public shareholders. The approval by the 쮸떴app shareholders of the issuance of the Series C common shares in the proposed transaction would also be required under applicable Nasdaq Stock Market

requirements. Other than applicable filings with the Securities and Exchange Commission, 쮸떴app does not anticipate that any additional regulatory approvals would be required.
