Sirius XM Holdings Inc. insider Eddy W. Hartenstein reported a change in the form of his ownership of Sirius XM common stock on July 13, 2026, according to a Form 4 filed July 14, 2026. The reported transaction involved 6,688 shares of SIRI common stock transferred at a reported price of $0.00 per share. The filing explains that Hartenstein transferred the shares to the Hartenstein Family Trust. Because Hartenstein and members of his immediate family are the sole beneficiaries of the trust, the transfer did not represent an open-market sale or purchase. The explanatory note states that Hartenstein remains the beneficial owner of the securities held by the trust. In practical terms, the filing reflects an estate-planning or ownership-structure transfer rather than a disposal of economic interest in Sirius XM shares. The document does not provide a separate post-transaction ownership total beyond the 6,688 shares involved in the transfer, nor does it list a cash purchase or sale price. The filing was signed on Hartenstein’s behalf by Ruth Ziegler, attorney-in-fact, on July 14, 2026.

About the company
Sirius XM Holdings, Inc
Sirius XM operates almost exclusively in the US through its SiriusXM and Pandora audio services. SiriusXM is primarily a satellite radio service that offers nationwide coverage and mostly ad-free listening, with proprietary channels and exclusive content. It makes agreements with automakers to install its radios in vehicles and give trial services to vehicle buyers, which have traditionally fed its subscriber base. The company provides the service via a fleet of geostationary satellites it owns and operates and now offers a streaming SiriusXM option. Pandora, which accounts for a much smaller portion of revenue and profit, offers a subscription and ad-supported streaming music service that competes with industry giants such as Spotify, Apple Music, and YouTube Music.
