We have identified our Federal Communications Commission (“FCC”) licenses and XM and Pandora trademarks as indefinite life intangible assets after considering the expected use of the assets, the regulatory and economic environment within which they are used and the effects of obsolescence on their use.

We hold FCC licenses to use 35 MHz of contiguous spectrum to operate our satellite digital audio radio service, provide ancillary services and services in the adjacent bands. Each of the FCC licenses authorizes us to use radio spectrum, a reusable resource that does not deplete or exhaust over time. These FCC licenses allow us the use of 25 MHz for our Sirius and XM satellite networks (12.5 MHz for the Sirius network at 2320-2332.5 MHz and 12.5 MHz for the XM network at 2332.5-2345 MHz). In 2024, we acquired the licenses in the Wireless Communications Service (“WCS”) C and D Blocks. This WCS spectrum consists of 5 MHz of unpaired blocks each, with “C block” located at 2315-2320 MHz and “D block” located at 2345-2350 MHz.

Our annual impairment assessment of our identifiable indefinite lived intangible assets is performed as of the fourth quarter of each year. An assessment is performed at other times if an event occurs or circumstances change that would more likely than not reduce the fair value of the asset below its carrying value. If the carrying value of the intangible assets exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. As of June 30, 2026, there were no indicators of impairment, and no impairment loss was recognized for intangible assets with indefinite lives during the three and six months ended June 30, 2026 and 2025.

Amortization expense for all definite life intangible assets was $31 for each of the three months ended June 30, 2026 and 2025, and $62 for each of the six months ended June 30, 2026 and 2025. There were no retirements or impairments of definite lived intangible assets during the six months ended June 30, 2026 and 2025.
