T-Mobile US falls after reports SpaceX seeks access to U.S. cell sites ahead of earnings

What happened

T-Mobile US (TMUS) fell 7.7% on October 23, 2026, after reports that SpaceX is seeking access to at least 80,000 U.S. cell sites. The move came as analysts prepared and published estimates ahead of the company’s Q3 2026 earnings due October 28, 2026, with commentary noting expected subscriber gains and rising costs. The stock opened 5.2% below the previous close and trading volume was 1.5 times its 20-day average, according to Benzinga and 24/7 Wall Street.

How big was the move

The stock’s session change was 2.8 times a typical daily move for this stock and was 6.7 percentage points worse than the Communication Services sector median, which fell 1.0% on the day. The S&P 500 fell 0.5% on October 23, 2026. Over the last five sessions the stock fell 7.9% while the S&P 500 over five sessions fell 0.5%. With a beta of 0.35, the stock tends to move less than the market, so the size of this drop points to a large, mostly company-specific move; company news is the likely driver.

The technical picture

The stock sat 8.1% below its 20-day moving average and 14.0% below its 50-day moving average. It was 22.1% below its 200-day moving average, with the 50-day average below the 200-day average, a sign of a weak longer-term trend. The Relative Strength Index (14 days) was 35, in a neutral range between 30 and 70. The stock was 35.1% below its 52-week high. Over one month the stock fell 11.4% and over three months it fell 17.3%. Over one year it fell 35.6%, trailing the S&P 500 by 49.4 percentage points. Volatility was 44% annualized over 60 days, the highest reading of the past five years.

Fundamentals and valuation

Price to forward earnings was 13.4 times expected earnings and free-cash-flow yield was 9.0%.

Earnings and analyst expectations

T-Mobile’s next report was scheduled for October 28, 2026. The company’s last report, on July 23, 2026, delivered earnings per share of $2.99 against $2.59 expected, 15.4% above estimates. The company had two consecutive quarters beating estimates and an average surprise over the last four reports of 7.0% above estimates. The typical two-day reaction after recent reports was rose 0.2%.

Analysts show a consensus rating of Buy. The consensus price target was $221.75, 51.3% above the closing price, based on 54 analysts with a rating, with 81% of ratings at Buy or Strong Buy. That gap between the street target and the market price highlights differing views: valuations and cash flow measures point to relative cheapness, while recent price momentum and macro risks may be limiting upside.
