T Mobile (TMUS) Stock May Be A Bargain After Raised Outlook

Simply Wall St·11/03/2026 08:23:44
Listen to the news

T-Mobile US has seen its share price move around over the past few years, and that raises a straightforward question for you as an investor: Is the current valuation of T-Mobile US stock properly grounded in the earnings the business is generating today?

  • Over the past 5 years the stock has returned 39.4%, which puts quite a bit of weight on whether the current earnings power can support that journey so far.
  • Recent reports on cybersecurity upgrades, network performance and new fiber offerings may support expectations around future profitability and the timing of cash flows, which all feed back into how much investors are prepared to pay for each dollar of earnings.
  • Your read on T-Mobile US is one view; the desks covering it have another. See what analysts think T-Mobile US's shares could be worth.

The issue now is whether T-Mobile US stock at around US$160 per share is appropriately aligned with what its earnings justify.

Does T-Mobile US Look Undervalued on Earnings?

The P/E ratio is a useful shorthand for T-Mobile US because earnings are now a central focus for how investors value large wireless carriers. At around 15.0x earnings, the stock trades very close to the Wireless Telecom industry average of about 14.9x. This frames it as broadly in line with the sector on this single measure.

Against a broader peer set that averages roughly 33.6x, T-Mobile US changes hands at a much lower multiple, so the market is not pricing it like the higher rated telecom and adjacent players. A fair P/E based on a more tailored model that considers T-Mobile US specific growth profile, margins, size and risk comes out above the current ratio. This points to the shares screening undervalued on this framework. Because the company recently reported higher earnings and raised its profitability outlook, that discount on P/E may catch the eye of investors comparing it with other telecom stocks.
