The News: For Q3 FY 2025, T-Mobile reported total revenue of $22.0 billion (in line with consensus estimates), up 8.9% year-on-year (YoY). Service revenue rose 9.1% YoY to $18.2 billion, and postpaid service revenue grew 11.8% YoY to $14.9 billion. Core Adjusted EBITDA increased 5.6% YoY to $8.7 billion. Net income was $2.7 billion (down 11.3% YoY), and diluted earnings per share (EPS) were $2.41 (down 7.7% YoY).
“It is a privilege for me to lead this incredible team and continue building upon the tremendous Un-carrier legacy. We are even more convicted in our future than ever before, as we continue taking profitable share through wireless, through broadband, and smart adjacencies, investing to defend our network leadership, while further improving network perception, and effecting a digital transformation,” said Srini Gopalan, COO and incoming CEO.
T-Mobile Q3 FY 2025: Posts Record Q3 Adds; Raises FY 2025 Guidance
Analyst Take: T-Mobile’s quarter showcased durable, profitable growth powered by a widening differentiation flywheel: demonstrable network performance leadership, increasingly digital customer journeys, and a scaled broadband strategy that pairs fallow-capacity, fixed wireless access (FWA) with capital-light fiber. Management emphasized rising network perception among switchers and accelerating digital-led sales—both material tailwinds in high-promo periods such as the iPhone 17 cycle. The company is also moving quickly on UScellular integration to extend coverage, densify spectrum, and unlock synergies on an accelerated timeline. With guidance lifted across customer and financial measures, T-Mobile enters year-end positioned to compound gains into FY 2026.
Network leadership and digital acquisition momentum
Management cited an all-time high network perception among switchers in Q3, aligning with external speed data on iPhone 17 showing median download speeds nearly 90% faster than one benchmark competitor and more than 40% faster than the other. Digital is now a material acquisition lever, with three out of four iPhone upgrades during the preorder window executed digitally, reducing friction and inertia for switchers. T-Mobile highlighted account-level growth breadth across the top 100, smaller markets, and rural areas, indicating balanced acquisition beyond traditional urban strongholds. Organic postpaid average revenue per account (ARPA) growth of approximately 3.8% (excluding UScellular and fiber JVs) suggests that migration to higher-value plans holds even in a promo-heavy environment. The implication: network plus digital creates a reinforcing loop that lowers acquisition friction while supporting ARPA resilience.
Broadband expansion: FWA and fiber JVs
Broadband remains a second growth engine, with 560 thousand total broadband net adds (+34% YoY), including 506 thousand 5G broadband (+22% YoY) and 54 thousand fiber additions. FWA continues to scale on a fallow-capacity model. Over two years, T-Mobile nearly doubled its FWA customer base while per-customer usage rose ~30% to a reported ~580 gigabytes per month, yet average download speeds increased nearly 50%. Management noted FWA ARPUs and lifetime values are broadly similar to postpaid phone, supporting attractive contribution economics. Fiber strategy remains capital-light via JVs, prioritizing first/near-first-to-fiber markets and leveraging brand, distribution, and partner build expertise; T-Mobile closed the Metronet transaction on July 24 and continues to assess assets that meet returns and structure criteria. The company reiterated a national ambition anchored by FWA scale with selective fiber penetration in markets where JV structures support outsized returns. The takeaway: broadband mix-shifts toward FWA and targeted fiber should diversify growth while maintaining disciplined capital intensity.
UScellular integration and synergy capture
Following the August close, T-Mobile absorbed UScellular customers and spectrum in 21 states, immediately improving customer experience (e.g., coverage, T-Mobile Tuesdays) while initiating a Sprint-style integration playbook. Management lifted total OpEx and capex run-rate synergy targets to $1.2 billion and pulled forward the timeline to within two years of close, with the vast majority of “costs to achieve” expected in FY 2026 and full run-rate synergies by the end of FY 2027. Q4 will reflect approximately $300 million in merger-related costs (excluded from Core Adjusted EBITDA) and about $160 million for cell site decommissioning as part of a broader network transformation focused on location optimization. The integration accelerates a larger network modernization agenda—adding densification and spectrum re-farming to widen performance gaps versus peers. With added coverage and spectrum depth, UScellular strengthens the foundation for both wireless and FWA capacity, where T-Mobile intends to grow share.
Guidance and Final Thoughts
T-Mobile raised FY 2025 guidance: total postpaid net adds to 7.2–7.4 million (prior: 6.1-6.4 million), Core Adjusted EBITDA to $33.7–$33.9 billion (prior: $33.3-33.7 billion), capex to approximately $10.0 billion (prior: $9.5 billion; including UScellular-related investments), and Adjusted Free Cash Flow to $17.8–$18.0 billion (prior: $17.6-18 billion). The company also increased fiber net add guidance to approximately 130 thousand (prior: 100 thousand), reflecting momentum in T-Fiber and recent JV transactions. Overall, T-Mobile is positioned to defend share gains under heightened promotional intensity via performance, plan value, digital ease, and expanding broadband reach.
