FOR IMMEDIATE RELEASE

SIRIUSXM ANNOUNCES EXPIRATION OF CONSENT SOLICITATION

WITH RESPECT TO PANDORA MEDIA’S CONVERTIBLE NOTES DUE 2023

NEW YORK – January 31, 2019 – Sirius XM Holdings Inc. (NASDAQ: SIRI) today announced that the previously announced consent solicitation by Sirius XM Radio Inc., its subsidiary, with respect to certain proposed amendments to the indenture governing Pandora Media, Inc.’s 1.75% Convertible Senior Notes due 2023 (the “2023 Notes”) expired at 5:00 p.m., New York City time, on January 31, 2019 (the “2023 Notes Expiration Time”). As of the 2023 Notes Expiration Time, Sirius XM Radio Inc. had received valid consents in respect of at least a majority of the aggregate principal amount of all outstanding 2023 Notes (the “2023 Notes Requisite Consents”) to the proposed amendments with respect to the indenture governing the 2023 Notes. Promptly upon receipt of the 2023 Notes Requisite Consents on January 31, 2019, Pandora Media, Inc. and Citibank, N.A., the trustee under the indenture for the 2023 Notes, entered into a supplemental indenture to the indenture governing the 2023 Notes implementing the proposed amendments with respect to the 2023 Notes, at which time such supplemental indenture became effective.

Subject to the terms and conditions set forth in the Consent Solicitation Statement, dated January 18, 2019 (as supplemented, including by the Supplement dated January 31, 2019), and the related consent form, including that all conditions precedent to the closing of the Acquisition (defined below) have been satisfied or waived at or prior to February 15, 2019 (the “Consent Conditions Outside Date”), holders of 2023 Notes as of 5:00 p.m., New York City time, on January 17, 2019 whose consents were received (and not validly revoked) at or prior to the 2023 Notes Expiration Time, will be eligible to receive a cash payment (the “Consent Fee”) of $3.75 per $1,000 principal amount of such Notes, promptly after all conditions to the consent solicitation shall have been satisfied or waived, and in no event later than the closing date of the Acquisition. Holders of 2023 Notes that provide consents after the 2023 Notes Expiration Time will not receive the Consent Fee.

The proposed amendments will become operative only upon the payment of the Consent Fee, which Sirius XM Radio Inc. expects to occur on the closing date of Sirius XM Holdings Inc.’s previously announced acquisition of Pandora Media, Inc. (the “Acquisition”). If the Consent Fee is not paid, the proposed amendments will not become operative and will be deemed to be revoked retroactively to the date of the supplemental indenture. Upon the proposed amendments becoming effective and operative, all the holders of the 2023 Notes and their respective transferees will be bound by the terms thereof, even if they did not deliver consents to the proposed amendments.

BofA Merrill Lynch acted as solicitation agent in connection with the consent solicitation. D.F. King & Co., Inc. is acting as the information, tabulation and paying agent for the consent solicitations. Questions may be directed to D.F. King at (800) 676-7437 (toll free) or (212) 269-5550 (bankers and brokers).

This announcement is neither an offer to purchase nor a solicitation of an offer to sell the 2023 Notes.
