Bernstein downgrades AT&T on SpaceX foray into wireless

Bernstein downgraded AT&T to Market Perform from Outperform and cut its price target to $24 from $25, citing competitive pressure from SpaceX's expanding Starlink broadband and wireless capacity, incumbent pricing moves, and expected Q4 seasonality. The new target implies about 7% upside from Monday's close; Bernstein said Starlink's disruption remains uncertain but the competitive overhang may persist as its V3 constellation scales. AT&T shares are down more than 9% in 2026, while SpaceX is up 17% over the past three months; 15 of 27 analysts covering AT&T have Buy or Strong Buy ratings.

Analysis

The relevant risk to AT&T is not near-term subscriber substitution so much as a change in the market’s pricing assumptions: a credible satellite alternative can make terrestrial carriers defend retention with promotions before Starlink has enough capacity or handset compatibility to serve dense markets at scale. That could pressure service revenue and margins across incumbent wireless operators, not just AT&T; fixed-wireless providers also face a competing coverage proposition. Conversely, satellite connectivity is more likely to complement terrestrial networks in low-density and coverage-gap use cases initially, limiting the case for an immediate broad-based earnings impairment.

The downgrade is a sentiment catalyst, not evidence of a quantified change to AT&T’s earnings power. Over the next 1–3 months, watch AT&T’s churn, postpaid net additions, promotional intensity and service-revenue outlook, alongside verified Starlink availability, capacity and device support. Over 6–18 months, the structural question is whether satellite capacity and spectrum access let SpaceX offer a sufficiently reliable, competitively priced service beyond a niche coverage product. The consensus skew toward positive ratings may leave room for further estimate or multiple pressure if incumbents concede pricing, but the risk is that the market overstates the pace of substitution. Bernstein’s involvement in SpaceX’s IPO is context for weighing the call, not by itself a reason to dismiss it.

Key Decisions for Investors

• Consider a modest relative underweight in T versus a diversified incumbent-telecom peer basket rather than an outright short: the more plausible near-term channel is sector-wide promotional pressure, while direct displacement remains unproven. Reassess after AT&T’s next operating update.
• Do not chase SPCX solely on this thesis. Its upside depends on capacity, compatible devices, spectrum/regulatory access and service economics; verify commercial availability and adoption before treating satellite expansion as incremental earnings.
• Falsify the cautious T view if AT&T sustains postpaid growth and stable churn/service revenue without elevated promotions while Starlink’s capacity, compatibility or regulatory rollout falls short. Escalate the underweight if AT&T signals worsening churn or pricing concessions and Starlink demonstrates broader commercial reach.
