Is T-Mobile Stock Worth More Than Its Competitors?

Investors are paying a premium for T-Mobile US (TMUS). The stock currently trades at 17.2 times earnings, representing the highest P/E multiple among its telecom and cable peers. Buyers are clearly betting on top-line expansion, as T-Mobile is generating faster revenue growth than its competitors. This advantage has not translated to industry-leading profitability, however, because its operating margin ranks only fourth of the six. So how wide is T-Mobile’s growth lead over its rivals?

T-Mobile’s Revenue Rose At Over Three Times AT&T’s Rate

Over the last twelve months, T-Mobile increased its revenue by 9.7%. That easily outpaces the 2.6% growth at AT&T, but investors pay heavily for the difference. AT&T trades at 7.9 times earnings, which is less than half the multiple commanded by T-Mobile. Underneath those valuations, both companies convert almost the exact same share of each sales dollar into operating profit: 20.1% at T-Mobile and 20.6% at AT&T. Market participants are therefore financing faster top-line growth without securing any extra profitability in return.

T-Mobile outpaces every competitor in both top-line growth and earnings valuation. Verizon Communications, for example, posted just 1.4% revenue growth and trades at 11.8 times earnings. Direct comparisons remain imprecise because these underlying business models differ. T-Mobile operates as a wireless carrier, whereas AT&T and Verizon are integrated telecom companies. Similarly, Comcast and Charter Communications rely on selling cable.

Are Customers Or An Acquisition Lifting T-Mobile’s Sales?

Both organic customer gains and a recent acquisition are likely driving these higher sales figures. T-Mobile is successfully attracting customers on monthly plans. During the earnings call for the second quarter of 2026, executives noted that revenue from these postpaid customers rose 13%. The carrier added a net 277,000 postpaid accounts in that same period. Furthermore, more than 60% of these new accounts chose premium plans. The company is actively expanding its user base while selling new customers its more expensive service tiers.

Inorganic expansion likely plays a role as well. T-Mobile acquired UScellular last year. Executives pointed out that results for the first two quarters of 2026 are measured against year-ago quarters that predated the buyout. This integration likely lifts the current growth rate, meaning the stated revenue advantage over AT&T has yet to be proven on equal footing.

What Has T-Mobile Forecast For Its Third Quarter?

Executives are now preparing investors for a deceleration. T-Mobile forecast service revenue of about $19.3 billion for the third quarter of 2026, representing a 6% increase from a year earlier. For context, service revenue grew 9% during the second quarter. The company also adjusted its older rate plans in the third quarter, a move executives expect will temporarily cost more accounts than usual. They anticipate a smaller effect on phone-line losses, noting that the pricing changes fall mostly on accounts with fewer lines. T-Mobile will report its third-quarter results on October 28, 2026.

The premium valuation has not rewarded current shareholders. T-Mobile stock lost 23.9% over the past twelve months. By comparison, Verizon stock gained 18.0% during the same period.

Investors paying these prices appear to assume T-Mobile will maintain a comfortable growth margin over AT&T and Verizon even after the acquisition boost fades. The ongoing migration of customers to T-Mobile and its premium plans certainly supports this optimistic outlook. Yet the company must still prove how much underlying momentum exists without the benefit of newly purchased assets. If the upcoming earnings report reveals service revenue growth above the roughly 6% forecast for the third quarter, it will suggest T-Mobile is still pulling in customers.

How To Act On TMUS?
