EchoStar (SATS) sold its AWS-3 spectrum licenses to SpaceX for $2.6 billion in stock, a 73% discount to their $9.8 billion book value, to avoid FCC risks and a 2026 re-auction. The sale follows a $23 billion spectrum deal with AT&T in August. Despite the move, shares fell 2.3% premarket after a steep Q3 loss, though Stocktwits sentiment turned bullish.
