T-Mobile US, Inc.

Key catalysts

• Postpaid account and ARPA growth

  Continued postpaid account growth and higher average revenue per account can support durable service-revenue and cash-flow expansion.

• UScellular integration

  Integrating acquired UScellular operations and spectrum can expand reach, improve network utilization and create operating synergies.

• Broadband expansion

  Fixed wireless and fiber expansion through the Metronet and Lumos platforms can deepen household relationships beyond mobile service.

Principal risks

• Competition and promotions

  Aggressive wireless and broadband competition can require richer promotions, increase churn risk and pressure customer economics.

• Integration and capital intensity

  UScellular and fiber-platform integration, network investment and spectrum commitments may raise costs or delay expected returns.

• Regulatory and network exposure

  Spectrum regulation, transaction commitments, outages, cybersecurity incidents and customer-data breaches can create financial and reputational damage.

T-Mobile reported results for the quarter ended March 31, 2026, highlighting postpaid account and average-revenue-per-account growth, acquisition-supported service revenue expansion and increased full-year guidance.

Valuation interpretation

• A resilient cash-flow interpretation depends on sustaining postpaid account and ARPA growth while keeping promotional and network costs controlled.
• Acquisition and broadband optionality should be weighed against integration risk, capital intensity and the time required for synergies to emerge.
