SpaceX’s spectrum deal puts SIRI’s satellite assets in focus
SpaceX agreed to pay $8 billion for Grain Management’s 800 MHz spectrum, signaling the value of licensed radio-frequency assets. Sirius XM (SIRI) owns S-band satellite spectrum, which, if valued similarly, could imply a $14.3 billion worth, above its $9.1 billion market cap. SIRI shares rose 2.43% on Friday. Analysts see potential upside, with a consensus target of $33.78. The FCC’s upcoming spectrum rules and SIRI’s Q3 earnings call on October 29 may impact its valuation.
