T-Mobile Stock Rises on Record Q4 Subscriber Growth and 5G Broadband Strength

T-Mobile ended the year 2025 with quite strong fourth-quarter results, which is why it can be concluded that its integrative strategy that combines the network quality, value offering, and customer experience is effective.

In the 4^th quarter, the firm posted $2.4million postpaid subscribers, adding up to the leading industry record. The net addition of customers as postpaid throughout the fiscal year reached $7.8 million customers, which justifies the fact that T-Mobile continues to attract a larger proportion of high-value customers compared to its major rivals.

The organization also simultaneously earned 962,000 postpaid telephone customers in the fourth quarter and $3.3 million during the year. Moreover, the net additions to postpaid accounts were 261,000 and $1.2 million in Q4 and 2025, respectively.

These indicators are important because account growth shows that not only individual consumers are going to T-Mobile, but whole households and businesses as well.

The Broadband development reinforces the commercial combination 

The other critical deciding factor of the performance of T-Mobile is its fast-growing broadband portfolio. The company has 558,000 broadband subscribers onboarded in the fourth quarter of 2025. Within the entire fiscal year, the broadband net additions came in at $2.00 million, out of which the 5G broadband subscribers were $1.90 million, and increased the total number of 5G broadband subscribers to $8.50 million customers at the end of the year.

This kind of intense increase in broadband will enable T-Mobile to diversify its sources of revenue and establish deeper relationships with its customers. In addition, it supports long-term growth, as broadband services are generally characterized by a high retention rate and predictable demand.

Purchaser growing interprets into hard economic consequences 

The customer performance was also robust, and this directly contributed to increased revenues and cash. Service revenues have grown to $18.7 billion dollars in Q4, 2025 and $71.3 billion dollars on an annual basis.

Only in the fourth quarter, postpaid service revenues amounted to $15.4 billion dollars, and in 2025, to $57.9 billion dollars, which indicates gradual progress in the most lucrative part of the company. The fourth-quarter net income increased to $2.1 b billion dollars and $11.0 b billion dollars in the whole year.

Diluted earnings per share stood at $1.88 dollars in Q4 and $9.72 dollars in the entire year, which depicts the fact that T-Mobile not only manages to achieve growth in terms of customer base but translates the same into actual profitability.

At Q4, Core Adjusted EBITDA was $8.4 billion dollars, and in 2025 $33.9 billion dollars. The net cash provided by operating activities had risen to $6.7 billion dollars and $28.0 billion dollars, respectively, in the quarter and the year.

Adjusted Free Cash Flow was $4.2 billion dollars in Q4 and $18 billion dollars in the year 2025, which indicates a high degree of cash efficiency.

Constructive viewpoint for 2026 provision longstanding growing 

The network performance of T-Mobile was a key factor that determined its auspicious outcomes. T-Mobile had the highest rating in terms of network quality in 5 of the 6 regions for the first time. It was a significant change in the perception of consumers and an end to a long phase where one of the competitors held control of the category. The company also won all five overall network experience awards from Open signal, such as 5G coverage and availability.

Moreover, Ookla recognized T-Mobile as the most popular mobile network in the United States and awarded it the fastest 5G network and remarkable performance in mobile gaming and video streaming.

Looking into the future, T-Mobile projects to grow its portfolio by about $900,000 to $1.0 million net postpaid accounts in 2026. Core Adjusted EBITDA will reach $37.0 to $37.5 billion dollars.

The business also estimates that it will run with cash flow between $28.0 and $28.7 billion dollars and Adjusted Free Cash Flow of between $18.0 and $18.7 billion dollars. Altogether, the Q4 and the overall year results prove that the expanding gap in network quality and customer experience at T- Mobile is already converting into long-lasting and profitable expansion.

By 2026, the company will have a high level of sustained momentum, increasing customer demand and a notable competitive advantage.
