T-Mobile Stock: Is TMUS a Buy After a 29% Drawdown?
T-Mobile trades around $168.18 as I write this, within a few percent of its 52-week low of $164 and 29.1% below its 52-week high of $237. That’s a steep fall for a stock the market spent years treating as the steadiest story in telecom. The quarterly report on 2026-07-23 that triggered most of the damage actually beat estimates on revenue and earnings. That part gets left out.
Revenue that quarter came in at $22.8 billion, up 8% year over year, matching consensus closely, and full-year revenue of $88.3 billion is up from $81.4 billion the prior year. The stock still fell -10.7% that day, well beyond the average post-earnings move of 6.3%. What moved the stock wasn’t the numbers already in hand, it was guidance: management flagged that third-quarter net additions were tracking toward roughly 250,000, down from about 277,000 in the second quarter, and tied that softening to a shift toward higher-priced plans raising the risk of customer churn (Yahoo Finance, reported the day of the print). My thesis is that T-Mobile’s growth engine, the phone-subscriber machine that carried the stock for years, is decelerating faster than the multiple has adjusted for, and the next couple of quarters of net-add data will tell you whether this is a pause or a turn.
The subscriber math that spooked the market
T-Mobile spent the better part of a decade undercutting Verizon and AT&T on price and network quality, helped by a large swath of mid-band spectrum that came out of the Sprint merger and turned out to be exactly the right spectrum for building fast, wide-coverage 5G networks. That strategy worked: T-Mobile led the industry in postpaid phone net additions for years running. The guidance cut isn’t a claim that the strategy failed, it’s a signal that raising prices on existing plans, a lever T-Mobile has increasingly reached for to protect margins, comes with a churn cost that shows up in the net-add line before it shows up anywhere else.
That’s a normal trade-off for a maturing subscriber business, not obviously a red flag, but it does complicate the growth story the stock had been priced for. Operating margin of 21% and net margin of 12% are both solid, and gross margin held close to flat at 62.9% versus 63.6% a year earlier, so this isn’t a business losing pricing power in aggregate. It’s a business trading a bit of unit growth for revenue per user, and the market decided that trade was worth a lot less than the multiple assumed.
A valuation that no longer matches the growth story
Here’s the part of this that I find strange: T-Mobile’s trailing P/E of 17.6 is now well below its five-year average of 40.3, a gap that size usually shows up in a business the market expects to shrink, not one still growing revenue at 8% a year. Forward earnings of $11.23 imply 17% growth from the trailing $9.56, and the forward multiple of 15.0 times is cheap for a company with T-Mobile’s margin profile if that growth shows up. Price-to-sales, at 2.1 against a 2.5 five-year average, tells the same story: the stock has been marked down more than the reported numbers, on their own, would justify.
The disconnect gets sharper when I look at where analysts actually think this stock should trade. The average price target is $243, which is 44% above the current price, and even the low estimate of $215 still implies 28% upside. Eighty-eight percent of the 16 analysts covering the stock rate it a buy. That’s lopsided. It sits oddly next to a quant rating that moved from a C to a E, the kind of split I don’t see often: a model reading the recent trend as a warning sign while the analyst community, working off longer-horizon estimates, hasn’t budged. I read that gap as the market pricing near-term churn risk while the sell side is still pricing the multi-year subscriber franchise, and it’s not clear to me yet which horizon is right.
I ran into a similar split, quant score down, analyst targets still high, when I looked at SoFi after its bank charter began paying off; in that case the quant read caught up to reality within two quarters. I don’t think that pattern is guaranteed to repeat here, it’s a data point, not a rule.
| Metric | T-Mobile now | Five-year average / recent comparison |
|---|---|---|
| P/E (trailing) | 17.6 | 40.3 |
| P/E (forward) | 15.0 | — |
| P/S | 2.1 | 2.5 |
| Revenue (FY2025) | $88.3 billion | $81.4 billion prior year (+8%) |
| Operating margin | 21% | Net margin 12% |
| Q2 2026 net adds | ~277,000 | Q3 2026 guided to ~250,000 |
| Analyst target (avg) | $243 (44% upside) | Range $215–$280 |
| Quant rating | E | Was C |
Home internet and enterprise are still early
The part of T-Mobile’s growth story that doesn’t depend on phone-plan pricing is fixed wireless home internet and the enterprise and government push, both still early in their own growth curves relative to the core phone business. Home internet has a real ceiling, tied to the addressable footprint T-Mobile’s network can actually serve, unlike phone share, which can keep growing as long as T-Mobile keeps taking customers from rivals. I don’t have a verified, current subscriber count for either segment to cite here, so I’ll leave it qualitative: if phone net adds keep softening the way third-quarter guidance suggests, these two segments become the more important story faster than the market currently seems to be pricing, since they’re a smaller share of revenue today but a larger share of the growth.
I looked at a related dynamic in Ford’s two-speed business, where a mature, profitable core had to carry a newer, still-unproven growth segment through a rough patch. T-Mobile’s core isn’t unprofitable, that comparison only goes so far, but the pattern of the market discounting the whole story because of noise in the legacy segment is familiar.
What the dividend says about management’s own view
T-Mobile pays a 2.34% yield on $3.94 in trailing dividends, a payout that’s grown from essentially nothing a few years ago into a real piece of the capital-return story alongside buybacks. A telecom management team doesn’t commit to a growing dividend on top of an existing buyback program if it privately expects the churn problem flagged in July to turn into a multi-year growth reset; dividends are the one capital-allocation signal that’s expensive to walk back, and boards know it. I read the dividend trajectory as management’s own vote that the net-add softness is a pricing-strategy trade-off they’re managing deliberately, not a sign the franchise is cracking. That’s an inference, not a fact from a filing, and I want to flag it as such: it’s a reasonable read of incentives, not proof of anything about the next two quarters.
Set against a 17.6 trailing multiple, a 2.34% yield gives a holder something to collect while waiting for the net-add data to clarify. It’s not the reason to own the stock on its own, a sub-3% yield rarely is, but it’s a real difference from a stock priced for pure growth with no cushion if the growth stalls for a couple of quarters.
Reading the market-cap math against the peer set
T-Mobile’s market cap of $180.4 billion on $88.3 billion of revenue puts the stock at roughly 2.1 times sales, below its own 2.5-times five-year average and, on a business generating a 12% net margin and 21% operating margin, that’s a demanding combination for a bear case to explain away entirely with one quarter of soft guidance. Wireless is a business with real fixed-cost operating gearing once the network is built, and T-Mobile’s margins reflect a network that’s mostly already paid for. A stock doesn’t usually get marked down 29% from its high purely on a 27,000-subscriber gap in guidance unless the market is extrapolating that gap forward into a trend, which is exactly the extrapolation the next print will confirm or kill.
I’d also note the quarter-over-quarter revenue figure directly: $22.8 billion in the most recent quarter was down -1% sequentially even as it was up 8% year over year, a small sequential dip that’s consistent with a business absorbing the early churn effects of the plan-price changes rather than one accelerating cleanly. That sequential number, more than the year-over-year comparison everyone quotes, is the one I’d watch tick back to positive before getting more constructive on the stock.
Where this view breaks
The specific way I’d be wrong is if third-quarter net adds come in meaningfully below the guided 250,000, confirming that the pricier-plan strategy is doing more churn damage than management is currently signaling; a second consecutive guide-down on subscribers would justify a lower multiple, not just a one-quarter reset. The way I’d be wrong in the other direction is if net adds hold near guidance and average revenue per user keeps climbing, in which case a stock at 17.6 times trailing earnings against a 40.3-times historical average is simply cheap, and the 88% buy-rated analyst community turns out to have read this correctly while the quant model reacted to noise. Short interest is low, at 1.6% of the float, so I don’t think this is a stock the market is positioned to see fall further on autopilot.
The number I’d wait for is the actual third-quarter net-add print against that 250,000 guide. A beat there, with churn holding steady, would tell me the market overreacted to one data point on 2026-07-23. A miss would tell me the quant downgrade got there first.
