Bernstein analyst warns that SpaceX’s expanding satellite broadband could keep AT&T and other telecom stocks under pressure for an extended period
Executive summary: Bernstein analyst Laurent Yoon stopped recommending any major telecom stocks and warned that SpaceX’s satellite broadband business could create prolonged volatility for AT&T’s shares. The warning flags a competitive threat from SpaceX that could depress telecom earnings multiples and prompt further analyst downgrades, affecting sector allocation and stock prices.
Who is involved: Bernstein analyst Laurent Yoon, AT&T, SpaceX.
Likely next (inference): Market participants will watch SpaceX’s Starlink subscriber growth and upcoming telecom earnings reports for signs of impact, which could trigger additional rating changes.
Laurent Yoon of Bernstein has withdrawn his recommendation on major telecom carriers, citing heightened volatility ahead as SpaceX’s low‑earth‑orbit constellation gains traction. The note frames the threat as a structural competitive shift rather than a short‑term market ripple, suggesting that investors may need to reassess the growth outlook for traditional wireless providers. While the analyst does not quantify the potential loss of subscribers, the warning highlights a growing risk that satellite‑based services could erode market share and weigh on valuations.
What's next — scenarios
Inference: scenarios and probabilities are Beyond's assessment, not reported fact.
Base: Moderate pressure from SpaceX rollout (50%)
AT&T and peers experience modest share‑price volatility as Starlink subscriber base grows gradually.
- Starlink reaches 5 million active users globally within the next 6 months
- AT&T reports Q4 2026 churn in line with guidance
Upside: Telecom adapts via partnerships or new offerings (30%)
Carriers mitigate the threat by bundling 5G with satellite backhaul or forming alliances, limiting stock downside.
- AT&T announces a commercial agreement with SpaceX for backhaul services by Q2 2027
- Verizon launches a hybrid 5G‑satellite product in early 2027
Downside: SpaceX gains significant market share in broadband (20%)
Substantial subscriber shift to Starlink leads to deeper earnings cuts and multiple analyst downgrades across the sector.
- Starlink adds 10 million users in the United States by end‑2027
- FCC grants SpaceX additional spectrum for mobile‑backhaul use in late 2026
What to watch
- Starlink quarterly subscriber reports (expected Q1 2027)
- AT&T Q4 2026 earnings release (early February 2027)
