    T Mobile US (TMUS) Stock May Be Undervalued Despite Fresh Analyst Upgrade

    Listen to the news

    T-Mobile US has delivered a solid 5 year share price gain, and the recent pullback and fresh analyst attention put a sharper spotlight on whether its current market value lines up with what its earnings support. With the stock trading around US$158.79 after a mixed run this year, the key issue for you as an investor is how much of the story is already reflected in the profit it generates today.

    • T-Mobile US has returned 43.9% over the past 5 years, which raises the question of how much of that long term success is now embedded in the valuation attached to its earnings.
    • Recent analyst upgrades following strong reported profit and revenue, alongside views that potential competition from services like SpaceX may be several years away, can influence how durable investors expect T-Mobile US earnings to be.
    • The analysts covering T-Mobile US have run their own numbers. See what analysts think T-Mobile US's shares could be worth.

    The stock's next move may depend on whether its current price is adequately supported by the earnings that T-Mobile US is producing today.

    Is T-Mobile US a Bargain on Earnings?

    The P/E ratio fits T-Mobile US well because earnings are a key focus for a mature wireless telecom business. On this measure, the stock trades on about 16.1x earnings, which is slightly above the wider Wireless Telecom industry average of roughly 14.9x. Compared with a peer group closer to 34.0x, the multiple appears materially lower than many other large players in the sector.

    Because the recent analyst upgrades followed strong reported profit and revenue, the fact that T-Mobile US trades below the multiple implied by a tailored fair-value model based on its own growth profile, margins, scale and risk suggests that the shares may screen as undervalued on earnings. Despite the upbeat reaction to those Q2 results, the market is still pricing T-Mobile US at a P/E that sits beneath what this framework indicates could be justified by its fundamentals.
