TMUS shares dropped 6.13% to $179.24 on the day T-Mobile reported one of its stronger quarters in recent memory, a reaction that echoed what happened to Alphabet after its $112 billion profit quarter when the stock still lost 7%. Strong numbers, it seems, are no longer enough to hold a price.
Revenue and Earnings Held Up Well
Total service revenue climbed 9% year over year to $19.0 billion in Q2 2026. The postpaid segment did most of the heavy lifting, with postpaid service revenue rising 13% to $15.9 billion. That growth came from a combination of new accounts and higher spending per account: postpaid average revenue per account reached $152.91, up 2% from a year ago.
T-Mobile added 277,000 postpaid net accounts during the quarter. That number looks decent in isolation but is down from the 318,000 additions recorded in Q2 2025, which may have contributed to the sell-off. Total postpaid accounts stood at 34.7 million after base adjustments.
Net income came in at $3.2 billion despite merger-related costs tied to the UScellular acquisition. Diluted EPS grew 5% to $2.99. Core Adjusted EBITDA rose 12% to $9.5 billion. Operating cash flow increased 7% to $7.5 billion, and Adjusted Free Cash Flow advanced 4% to $4.8 billion even as capital expenditures jumped 13% to $2.7 billion. The company also raised its 2026 operating cash flow and free cash flow guidance, a signal that management sees the momentum continuing.
Shareholders received $3.3 billion through dividends and buybacks during the quarter. T-Mobile then repurchased an additional $392 million in shares between July 1 and July 17, already into Q3.
Network Benchmarks Swept Clean
On the network side, T-Mobile posted a record wireless Net Promoter Score of 46, the highest among the three largest U.S. carriers. Ookla named it the Best Mobile Network for the third consecutive report. Opensignal awarded the company across quality, network performance, and 5G experience categories. P3 went further: T-Mobile took all 13 available award categories in its benchmark, including the AI Services Champ designation.
That kind of clean sweep across independent testing organizations is unusual. It suggests the infrastructure spending, now running at $2.7 billion per quarter, is translating into measurable advantages rather than just accounting line items.
Why the Stock Dropped Anyway
Account growth decelerated. That single data point likely outweighed everything else in the eyes of growth-focused investors. When postpaid net adds slip from 318,000 to 277,000, the market starts asking how much headroom is left in a saturated U.S. wireless market. The raised cash flow guidance and the buyback program were not enough to offset that concern on the day of the report.
The broader pattern here is familiar: mature telecom companies generating strong cash flows but facing a ceiling on subscriber growth tend to trade on yield and capital return rather than revenue acceleration. T-Mobile has been trying to straddle both stories, and on this particular day, the growth story lost.
