AT&T Completes $23B EchoStar Spectrum Acquisition, Boosting 5G Capacity

T closed its previously announced acquisition of wireless spectrum licenses from EchoStar for approximately $23 billion, completing a transaction first announced in August 2025. The deal adds roughly 30 MHz of nationwide 3.45 GHz mid-band spectrum and roughly 20 MHz of nationwide 600 MHz low-band spectrum to AT&T's portfolio, covering effectively every U.S. market.

The two bands do different jobs. Mid-band 3.45 GHz carries the capacity and download-speed gains that show up in dense urban and suburban traffic, while 600 MHz low-band propagates further and through buildings, extending coverage depth rather than peak throughput. AT&T has said it intends to engineer the new holdings to strengthen the uplink side of its network, which is the constraint that matters for video upload, fixed wireless and machine-generated traffic. The company financed the purchase with term loans and cash and reaffirmed its existing financial outlook and capital allocation plan.

For EchoStar, the sale converts a long-held and largely unmonetized spectrum position into cash, and the question that follows is what remains of its wireless strategy once the licenses transfer. At least one report has flagged continued questions about the company's financial footing after the disposal. For AT&T, the item to watch is execution rather than the announcement: spectrum only becomes capacity once it is deployed, so the relevant markers are the deployment schedule, the capital intensity of that buildout, and whether the reaffirmed outlook holds as the spectrum is put into service.
