Beat-and-Raise Quarter Fails to Cushion Subscriber Blow
AT&T shares fell -6.88% to $21.79 on Oct. 21, 2026, after the company reported third-quarter results that beat on earnings and revenue but missed on the subscriber count that the market had been watching most closely.
The company reported third-quarter adjusted earnings per share of $0.65, up from $0.54 a year earlier and ahead of the $0.60 consensus estimate. Revenue rose 5.3% year on year to $32.3 billion, beating expectations of $31.7 billion. AT&T also raised its 2026 adjusted EPS outlook to around $2.40 and set a free cash flow target of at least $18 billion for the full year. On the broadband side, the company added a record 769,000 internet customers in the quarter, including 442,000 on fiber.
What the headline numbers could not offset was the wireless subscriber count. Postpaid phone net additions of 379,000 came in below analyst expectations of roughly 387,400, and the pace slowed from the prior quarter. Analysis suggests market drivers include concern that SpaceX's push into U.S. wireless — accelerated by its agreement to acquire a nationwide spectrum portfolio from Grain Management — could force carriers to spend more on customer incentives to defend their subscriber bases. SpaceX shares surged on the day.
The competitive threat drew a direct response on the earnings call. AT&T CEO John Stankey pushed back on the SpaceX concern, saying investors should not "over-rotate" on SpaceX's spectrum, and characterized low-Earth-orbit satellites as a complement to terrestrial networks in rural areas rather than a replacement. The reassurance did little to arrest the selloff. SpaceX President Gwynne Shotwell has separately said SpaceX expects to take "quite a few" customers from traditional carriers, as reported by TheStreet citing Benzinga. A non-cash write-down related to AT&T's Mexico operations also created a wide gap between reported GAAP EPS of $0.13 and the adjusted figure, adding a layer of noise to an otherwise beat-and-raise quarter.
Pressure Before and After the Print
The Oct. 21 drop came alongside broader weakness in the sector. The one-month period ending on Oct. 21 saw the stock decline about 14.58% in total, a figure that includes the earnings-day drop itself; the one-month high over that window was $25.74 and the low was $21.74.
Sector peers were not immune. Verizon and T-Mobile each fell on the day, coinciding with the broader attention on SpaceX's spectrum acquisition and its potential implications for established carrier economics.
Guidance Raised, but the Subscriber Question Stays Open
AT&T's raised 2026 EPS guidance and its commitment to double-digit adjusted earnings growth through 2028 give the company a clear financial narrative to defend. The company also lowered its planned capital investment for 2027 and 2028 to $22 billion to $23 billion annually, a detail that could matter to investors weighing the cost of competing in a market where a new entrant is building spectrum capacity.
The next test for the subscriber growth story will be the fourth-quarter earnings report. Until then, any further developments in SpaceX's spectrum buildout or pricing strategy are the variable most likely to move sentiment on AT&T.
Risk Factors
- Volatility risk: a single-session decline of -6.88% on a beat-and-raise quarter signals that subscriber growth expectations are a more sensitive driver than headline earnings, leaving the stock exposed to sharp moves on any further wireless data.
- Competitive risk: SpaceX's acquisition of a nationwide spectrum portfolio positions Starlink Mobile as a potential full-scale U.S. wireless carrier, a threat that analysis suggests could force higher customer incentive spending across the sector.
- Subscriber trajectory risk: postpaid phone net additions slowed sequentially even before a satellite competitor enters the market at scale; a further deceleration in Q4 could deepen the selloff.
- Earnings quality risk: the wide gap between GAAP EPS of $0.13 and adjusted EPS of $0.65, driven by a non-cash Mexico write-down, may prompt continued scrutiny of one-time items and complicate like-for-like comparisons with prior periods.
