T-Mobile US (TMUS) Valuation Check As New Device Fees Stir Fresh Questions On Customer Churn
Share
Listen to the news

T-Mobile US (TMUS) is drawing fresh attention after raising device restocking fees and introducing a $35 Device Connection Charge for Apple purchases, just as it faces higher customer cancellations and tougher wireless competition.

See our latest analysis for T-Mobile US.

The recent fee changes come after a softer 1-month share price return of 3.25% and a 1-day pullback of 1.83%, although the 3-year total shareholder return of 49.30% and 5-year total shareholder return of 66.21% still reflect a strong longer term outcome.

If this kind of pricing and competition story has you thinking more broadly about telecom and infrastructure plays, it could be worth scanning 26 power grid technology and infrastructure stocks

So with a softer recent share price, solid multi year returns, and valuation tools implying a large gap to estimated intrinsic value, is T-Mobile US offering a genuine entry point, or is the market already baking in future growth?

Most Popular Narrative: 4.1% Overvalued

According to the widely followed narrative from WallStreetWontons, T-Mobile US has an estimated fair value of $201.69 versus the last close at $210.03, putting the current price slightly above that anchor.

T-Mobile’s aggressive rollout of its 5G network is a major growth driver. The company has been leading in 5G coverage and performance, which attracts more customers and increases service revenues.

Read the complete narrative.

Curious what kind of revenue path and profit margins need to line up for that fair value to work? The narrative leans on steady top line growth, rising earnings power and a future earnings multiple that assumes T-Mobile keeps earning its place alongside larger telecom peers without needing tech style expectations baked in.

Result: Fair Value of $201.69 (OVERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, the story can change quickly if intense competition pressures pricing or if regulatory and legal issues result in higher costs or limits on growth plans.

Another View: Cash Flows Paint a Very Different Picture

While the popular narrative points to a share price of $210.03 sitting about 4.1% above an estimated fair value of $201.69, the SWS DCF model points the other way, with a cash flow based value of $562.53 per share and TMUS trading roughly 62.7% below that level. If one framework indicates slight overvaluation and another indicates substantial undervaluation, which lens do you trust more when real cash is on the line?

Look into how the SWS DCF model arrives at its fair value.
