T-Mobile US, Inc. (NASDAQ: TMUS) ended Monday’s session slightly lower even as the broader market pushed higher in a holiday-thinned rally. After the closing bell on December 22, 2025, investors had three fresh inputs to digest: a Form 144 filing tied to Deutsche Telekom, a Bernstein rating update, and a new T-Mobile corporate “year in review” release—all arriving as traders brace for a heavy U.S. economic calendar before Tuesday’s open.
Below is a detailed look at what moved today, what’s showing up after-hours, and what to watch heading into Tuesday, December 23, 2025.
TMUS after-hours snapshot: where T-Mobile stock stands tonight
At the close (4:00 p.m. ET), TMUS finished at $195.76, down 0.49% on the day. MarketWatch
In after-hours trading (as of 5:06 p.m. ET), TMUS was quoted at $195.26, down about 0.26% from the closing print, with roughly 212.7K shares in after-hours volume. MarketWatch
Intraday, the stock traded in a range roughly around $194.78 (low) to $197.19 (high), keeping TMUS pinned near the lower end of its recent band. Investing
One important nuance for readers: after-hours quotes can change quickly and may reflect thinner liquidity than regular trading. Tonight’s pricing should be treated as a “last read,” not a guarantee of where TMUS opens Tuesday.
Market context: why “quiet” days can still matter in a holiday week
While TMUS drifted, U.S. equities broadly advanced to start a holiday-shortened week—helped by continued strength in technology shares and generally lighter risk-off hedging. Reuters reported the Dow rose 0.47%, the S&P 500 gained 0.64%, and the Nasdaq climbed 0.52% on Monday. Reuters
That matters for T-Mobile for two reasons:
- Liquidity is thinning into Christmas, and price moves can become more sensitive to single headlines, filings, or analyst notes. Reuters specifically flagged lighter volumes heading into the holiday. Reuters
- Interest-rate expectations still matter for capital-intensive telecoms. This week’s major economic releases (starting Tuesday morning) can shift yields—sometimes quickly—changing the market’s appetite for dividend payers and buyback stories.
The biggest TMUS headline today: Deutsche Telekom’s Form 144 filing
A key item on today’s tape: a Form 144 filing connected to Deutsche Telekom AG, listed as a 10% stockholder, showing an intent to sell 400,000 shares of T-Mobile common stock, with an aggregate market value of $78,692,000. The filing lists Santander US Capital Markets LLC as the broker and gives an approximate sale date of 12/22/2025. Streetinsider
Why this matters (and what it does not mean):
- A Form 144 is a notice of proposed sale, not proof that the shares have already been sold in the open market.
- The filing’s remarks also point to a Rule 10b5-1 trading plan adopted June 12, 2025, which contemplates sales of up to 5,000,000 shares within a defined window (noted as running through late December). Streetinsider
- In other words, this looks consistent with pre-planned selling mechanics, but it can still influence short-term sentiment because it reminds traders about potential incremental supply.
For Tuesday’s open, the practical takeaway is simple: watch whether the market treats this as “routine” or as a renewed overhang—especially with volumes expected to remain light.
Analyst update: Bernstein stays Neutral with a $265 target
Another piece of today’s narrative came from Bernstein: analyst Laurent Yoon reiterated a Neutral rating and kept a $265 price target on T-Mobile. MarketScreener
Even without a downgrade/upgrade, reiterations matter when a stock is hovering near recent lows: they can reinforce the market’s current “wait-and-see” posture—particularly as investors look ahead to 2026 catalysts and continued competition across U.S. wireless.
Corporate news: “Un-carrier Unwrapped 2025” highlights network and product momentum
T-Mobile also put out a broad corporate recap titled “Un-carrier Unwrapped 2025”, emphasizing network performance claims and product expansion.
Highlights included:
- T-Mobile saying it was named “America’s Best Mobile Network” by Ookla, citing large-scale testing and customer experience measures. Business Wire
- A statement that it was the first in the U.S. to launch “5G Advanced” nationwide, positioning that as an enabling layer for lower latency and next-gen experiences. Business Wire
- Continued emphasis on broadband expansion, including T-Mobile Fiber availability “in over 200 locations across 26 states,” following acquisitions referenced in the release. Business Wire
This kind of release typically isn’t a direct stock-moving event on its own, but it can support the bull case around network leadership and broader connectivity offerings—two themes that often sit underneath longer-term forecasts.
A support pillar investors keep coming back to: buybacks and dividends through 2026
Although not “new today,” the capital return framework remains central to how many investors model TMUS into 2026.
In a December 11 filing, T-Mobile disclosed that its board authorized a new shareholder return program of up to $14.6 billion through December 31, 2026, expected to include share repurchases and cash dividends. SEC
That same filing referenced a Q1 2026 cash dividend of $1.02 per share, payable March 12, 2026, to shareholders of record as of February 27, 2026. SEC
Why this matters going into Tuesday:
- When a mega-cap stock is trading near the lower end of its recent range, buyback authorization can act as “soft support”—not a floor, but a stabilizer in risk-off moments.
- At the same time, pre-planned selling by major holders (like a Form 144 notice) can be read as the other side of that coin: supply vs. support.
What to watch before Tuesday’s open: the macro calendar can move telecoms too
For Tuesday, December 23, the U.S. calendar is unusually busy for the week of Christmas, and these releases can shift rates and broad risk sentiment before the opening bell.
MarketWatch’s calendar lists key items including Q3 GDP (delayed report) and durable goods orders at 8:30 a.m. ET. MarketWatch
Investing.com’s preview also flags Consumer Confidence at 10:00 a.m. ET (with a consensus expectation referenced in the report) and New Home Sales at 3:00 p.m. ET. Investing
What that means specifically for TMUS:
- If data surprises to the upside and pushes yields higher, telecoms can sometimes lag as investors rotate toward more cyclically sensitive names.
- If data comes in soft and yields ease, dividend/buyback narratives can regain relative appeal, particularly in a low-volatility holiday tape.
Holiday trading hours: liquidity risk rises as Christmas approaches
Two schedule reminders that can affect Tuesday’s session psychology:
- The NYSE notes an early close on Wednesday, December 24, 2025 (1:00 p.m. ET). New York Stock Exchange
- Nasdaq’s holiday schedule also shows an early close on December 24 and a full market closure on Christmas Day (December 25). NASDAQ Trader
When markets head into shortened sessions, it’s common to see lighter institutional participation, which can make single-stock moves look “bigger” than the underlying news might justify.
Forecasts and price targets: where Wall Street is positioned on TMUS right now
Forecasts vary by data provider, but one widely-circulated view today is straightforward:
- Bernstein’s target: $265 (Neutral). MarketScreener
- Business Insider’s compilation shows a median analyst target around $243.19, with a high estimate of $300 and a low estimate of $184, alongside an overall consensus tilted to “buy” in that dataset. Businessinsider
For near-term traders, the more immediate focus is often the next major fundamental catalyst. Nasdaq’s earnings page indicates TMUS is expected to report earnings on February 11, 2026 (before market open). Nasdaq
