NEW YORK, December 29, 2025, 7:58 PM ET — After-hours
- T-Mobile shares were flat after hours after closing up about 1.1% at $203.15.
- U.S. stocks ended lower as big tech weakened, while telecom peers were mixed. 1
- Investors are looking ahead to T-Mobile’s Feb. 11 results and a planned update to 2026–27 financial targets. 2
T-Mobile US shares were little changed in after-hours trading on Monday, after finishing the regular session up about 1.1% at $203.15.
The gain stood out on a day when Wall Street pulled back, led by declines in heavyweight technology names. The S&P 500 ended down 0.35% and the Nasdaq fell 0.50%, Reuters reported. 1
That relative strength matters late in the year. Trading tends to thin out around the holidays, and investors often shift toward steadier sectors when volatility rises in higher-growth areas. 1
T-Mobile traded between $200.51 and $204.13 on Monday, with about 4.4 million shares changing hands.
The stock extended a four-session winning streak, outpacing some large telecom rivals during the session, MarketWatch data showed. 3
Among peers, Verizon was flat at $40.48 late Monday, while AT&T rose about 0.5% to $24.77.
Reuters attributed the broader market dip to weakness in tech and AI-linked shares after recent gains. “This is (not) the beginning of the end of the tech dominance,” said Hank Smith, director and head of investment strategy at Haverford Trust. 1
With U.S. markets closed Thursday for New Year’s Day, traders are bracing for light liquidity across the tape, Reuters said. The week’s calendar is also thin, with Fed minutes and a weekly jobless-claims reading on the radar. 1
For T-Mobile investors, the next major company catalyst is its fourth-quarter and full-year 2025 report on Feb. 11, 2026. Chief executive Srini Gopalan and the leadership team plan to pair the results with an update to financial targets for 2026 and 2027, the company said. 2
T-Mobile’s last earnings update in October leaned on subscriber momentum. The company said it raised its 2025 forecast for total postpaid net customer additions — customers who pay at the end of the month — to 7.2 million to 7.4 million. 4
That October report also flagged higher capital spending, with Reuters reporting the company lifted its annual capital expense forecast to about $10 billion, partly reflecting the inclusion of newly acquired UScellular. 4
Monday’s close left T-Mobile shares well below their 52-week high of $276.49 set on March 3, MarketWatch data showed. With the year-end tape prone to abrupt swings, traders will watch Tuesday for any rebalancing-driven moves and for signs that competitive pricing is easing across the U.S. wireless sector ahead of the Feb. 11 update. 3
