T-Mobile, Verizon, AT&T Stock News: SpaceX Buys Nationwide Spectrum
Two decisions in the first full week of October changed how investors are thinking about the three national wireless carriers.
What happened
On October 6 the Federal Communications Commission authorized SpaceX to launch and operate up to 15,000 next-generation Starlink Mobile satellites for direct-to-device service, according to trade coverage of the order. The same order waived a rule that had required a satellite operator to lease spectrum from a terrestrial carrier before offering mobile service, which is the piece that matters most for the carriers.
On October 8 Grain Management announced a definitive agreement to sell SpaceX its entire nationwide 800 MHz portfolio, described as up to 14 MHz of paired spectrum, according to the law firm that advised Grain. The price was not disclosed by the parties; press reports citing unnamed sources put it near $8 billion in cash, a figure that has not been confirmed. Grain had bought the same licenses from T-Mobile in a transaction that closed in August. The sale needs FCC approval.
Shares of TMUS, VZ and T fell after the announcements, with T-Mobile posting the largest single-day decline of the three on October 9.
Why low-band spectrum is the point
Satellite signals reach phones outdoors today. Low-band spectrum such as 800 MHz passes through walls far better than the higher bands SpaceX already controls, so owning it is a prerequisite for a service that works indoors. Owning spectrum outright, rather than leasing it from a carrier partner, is what the FCC waiver and the Grain deal together make possible.
What is still required
The FCC deferred action on several other bands SpaceX requested. Testing on the spectrum SpaceX is acquiring from EchoStar cannot begin until that transaction's second stage closes, scheduled for late 2027. Half of the approved constellation is due in orbit by October 2032. Phones also need radios that support the bands. None of this is a commercial service yet.
For the carriers, the questions worth tracking are whether SpaceX prices against them or partners with them, and how each carrier's own satellite partnership responds. ASTS, which competed for the same licenses, is the other company most directly affected.
