Satellite radio transmission expense measures the operating cost of delivering SiriusXM services across its distribution infrastructure.

The category includes operation and maintenance of terrestrial repeater networks, satellites, satellite telemetry and control systems, uplink facilities, studios, Internet delivery, 360L streaming, and connected-vehicle services.

"Satellite" transmission also includes streaming infrastructure

The name can sound narrower than the underlying expense. SiriusXM's transmission line is not limited to the cost of sending a signal through satellites.

It also includes streaming and connected-service delivery infrastructure, which means changes in hosting and digital distribution can affect the line even when the satellite network itself is unchanged.

2025 expense fell because hosting costs fell

SiriusXM reported $162 million of transmission expense in 2025, down 15% from $190 million in 2024. Management said the decline was driven primarily by lower hosting costs associated with its streaming platform.

That is a useful reminder that the cost base contains both physical broadcast infrastructure and digital-delivery economics.

Transmission expense is operating cost, not satellite investment

This line belongs to cost of services. It should not be treated as capital expenditures for satellites or other long-lived assets.

It is also separate from programming and content expense, which pays for the product being delivered, and customer service and billing expense, which supports subscriber accounts.

Keeping those layers separate helps distinguish content cost, customer-service cost, and delivery-infrastructure cost inside the satellite-radio operating model.

Part of the Satellite Radio Subscription & Distribution Economics

Connects self-pay and promotional subscriber scale, churn and ARPU with automaker-driven installation and acquisition economics, then links those customer economics to subscriber and advertising revenue plus the direct content, royalty, service, and transmission cost stack.

Where this concept fits

Subscription revenue and direct service cost stackCurrent relationship
Subscriber revenue is the core recurring revenue stream and advertising adds a smaller complementary source. Revenue-share and royalty, programming and content, customer service and billing, and transmission expenses show the major direct cost categories required to license, support, and deliver the service.

Subscriber base, retention, and monetization
Self-pay and paid-promotional subscribers compose the ending subscriber base, while net additions show its change through the period. Weighted average subscribers support the ARPU denominator, churn captures self-pay retention, and ARPU shows recurring monetization after preserving the issuer's connected-vehicle exclusion.

OEM distribution, installation volume, and acquisition economics
Installation volume captures satellite-radio placements in new vehicles and aftermarket shipments. Subscriber acquisition costs fund that distribution footprint, SAC per installation scales those costs after the issuer's radio-margin adjustment, and equipment revenue adds the related hardware monetization stream.
