T-Mobile US (TMUS) is scheduled to report Q3 2026 results on October 28, with management guiding service revenues of approximately $19.3 billion, reflecting about 6% year-over-year growth. This follows Q2 total revenues of $22.79 billion and aligns with analyst consensus estimates for total revenue in the $22.3–23.3 billion range. Growth stems primarily from postpaid average revenue per account (ARPA) expansion of 2–3% and sustained subscriber momentum, though postpaid net account additions are expected to moderate to around 250,000 amid legacy rate-plan modernization and elevated churn. Full-year service revenue guidance remains near $77 billion, supported by core adjusted EBITDA targets of $37.1–37.5 billion. Traders are monitoring these metrics alongside potential competitive pressures from satellite entrants for implications on the quarterly outcome.
