Bernstein Downgrades AT&T as SpaceX's Starlink Targets the Wireless Business

The telecom trade has a new worry with a rocket attached. Bernstein downgraded AT&T (T) to Market Perform from Outperform on Tuesday, pointing straight at SpaceX's expanding wireless ambitions.

The firm also trimmed its price target to $24 from $25. That implies roughly 7% upside from Monday's close, CNBC reported.

Analyst Laurent Yoon was blunt about the reason. The downgrade "does not reflect a meaningful change to our estimates." It reflects, in his words, a prolonged investor debate around Starlink's impact and pricing.

The trigger isn't hypothetical. Late Thursday, SpaceX announced a deal for low-band 800MHz spectrum, reported at about $8 billion, and shares of AT&T, Verizon and T-Mobile slid in after-hours trading, as Barron's reported.

Low-band matters because it travels farther and penetrates buildings, which has been the weak spot for satellite phone service. Most modern smartphones already support the band, so Starlink Mobile may not need special devices, according to Gotechtor's breakdown.

Regulators have helped, too. The FCC approved a next-generation constellation of 15,000 satellites and granted a waiver that removes a requirement to lease spectrum from an existing carrier. SpaceX currently delivers satellite connectivity through T-Mobile.

"The degree of disruption remains debatable, but the overhang is unlikely to subside as the V3 constellation scales and Starlink gains flexibility to compete more aggressively." — Laurent Yoon, Analyst, Bernstein

Bernstein says last month's Starship 14 mission, which deployed the first batch of Starlink V3 satellites, marks the start of a significant capacity expansion. More capacity means more room to chase customers on price.

Yoon also wrote that it's getting harder to justify an Outperform rating on incumbent operators "even at discounted prices," because volatility looks inevitable.

The call goes against the Street. Of 27 analysts covering AT&T, 15 rate it Buy or Strong Buy, per LSEG data. The stock is down more than 9% in 2026, while SpaceX shares are up 17% over three months.

One disclosure worth knowing: Bernstein was among the banks involved in SpaceX's IPO. That doesn't invalidate the call, but it's context when reading it.

The pressure is spreading beyond the U.S. Canaccord upgraded Canada's BCE to Buy on Tuesday, calling the move opportunistic after a rate-driven sell-off and a 5.5% drop on Friday tied to satellite fears. In other words, some analysts see the damage as already priced in.

The case for patience has legs. Bernstein says its estimates barely moved. AT&T's networks, bundles and customer base are real assets, and a satellite carrier building terrestrial coverage from scratch has a long road ahead.

The case for caution is about multiples. If Starlink triggers price competition, the market may not wait for the earnings damage to show up before it marks telecom stocks down again.

If you own AT&T for the dividend and stability, this is a prompt to review your thesis, not to panic. Watch Starlink Mobile pricing announcements, subscriber numbers, and what AT&T says about promotions and churn on its next earnings call. Q4 seasonality is another flag Bernstein raised.

There's also a dividend-investor angle. AT&T has been a defensive holding for many portfolios, and a pricing war would test that reputation. A downgrade to Market Perform isn't a Sell, though. Bernstein is saying the upside is limited, not that the business is broken.

Compare the three incumbents, too. If competition is the issue, Verizon and T-Mobile face the same Starlink overhang, and all three sold off together when the spectrum news broke. Don't assume a swap between them solves the problem.

Bottom line: the AT&T story hasn't changed overnight, but the debate has. For now, expect headlines, not earnings, to move the stock.
