F2 · shares: Ms. Witz was subject to the filing requirements under Section 16(a) of the Securities Exchange Act of 1934 while serving as an officer and/or director of Old Sirius XM since 2017. In the course of preparing this Form 4, the Issuer was unable to reconcile the reports filed by Ms. Witz under Section 16(a) with respect to Old Sirius XM with the information, including bank and brokerage account statements, provided by Ms. WItz. The Issuer believes that Ms Witz's ownership in new Old Sirius XM, as reported under Section 16(a), may have been overstated by 16,716 shares of common stock. As a result, Ms. Witz's reported ownership has been adjusted to reflect this discrepancy.
