TIM Brazil delivered steady financial and operational growth in the fourth quarter of 2025 and for the full year, supported by strong mobile services momentum, improving Ultrafibra performance, and continued 5G network expansion across Brazil.
Revenue growth outpaces inflation
TIM said total revenue rose 4.4 percent year on year in the fourth quarter of 2025 to R$ 6,920 million. Service revenue increased 5.1 percent to R$ 6,665 million. Mobile service revenue was R$ 6,305 million. Fixed service revenue was R$ 359 million.
For the full year 2025, revenue climbed 4.6 percent to R$ 26,625 million. Service Revenue grew 5.2 percent to R$ 25,856 million, outperforming Brazil’s annual inflation rate of 4.26 percent. Mobile service revenue was R$ 24,519 million. Fixed service revenue was R$ 1,337 million.
The company attributed the performance to the consistent growth of its mobile services business and a recovery in Ultrafibra.
TIM reported strong growth in its postpaid mobile business in 4Q25, with postpaid revenue rising 9.5 percent. Postpaid ARPU reached R$43.3, while ARPU excluding M2M rose to R$54.8. Growth was driven by customer migration to higher-value plans, stable churn at 0.8 percent, and annual price adjustments. For full-year 2025, postpaid revenue increased 11.2 percent.
Prepaid revenue decline continued to slow, falling 6.5 percent in the quarter as recharge levels stabilized, despite ongoing migration to postpaid plans. Prepaid ARPU reached R$14.8. For the year, prepaid revenue dropped 9.3 percent.
Fixed Service Revenue grew 9.4 percent in 4Q25, supported by TIM Ultrafibra, which posted 6.2 percent growth and FTTH ARPU of R$95.2. The company added more than 27,000 new fiber customers in the quarter and over 60,000 in 2025. For the full year, Fixed Service Revenue rose 0.4 percent, while TIM Ultrafibra declined 1.2 percent.
Mobile segment drives performance
Mobile Service Revenue (MSR), net of taxes and deductions, increased 4.8 percent year on year to R$6,305 million in the fourth quarter. For the full year, MSR grew 5.4 percent.
Growth was driven by continued strength in the postpaid segment and a slower decline in prepaid services. TIM’s monetization strategy pushed Mobile ARPU to a record R$33.7, representing a 4.2 percent increase year on year.
Client Generated Revenue (CGR), which excludes interconnection and other revenues, rose 6.3 percent year on year to R$5,897 million in the fourth quarter. The increase reflected higher revenue from TIM customers and non-TIM customers, with international roaming contributing significantly. CGR also grew 6.3 percent for the full year.
Digital services revenue declines
Customer Platform Revenue totaled R$48 million in the fourth quarter, declining 59.3 percent year on year due to a challenging comparison base. The previous year included revenues from the EXA partnership focused on digital services and mobile insurance. For the full year, this segment fell 41.2 percent.
Capex and 5G expansion
Capital expenditure reached R$1,347 million in the fourth quarter, down 2.0 percent year on year due to lower spending on network infrastructure. The Capex-to-Net Revenue ratio fell to 19.5 percent, down 1.3 percentage points year on year.
For the full year 2025, Capex totaled R$4,541 million, remaining broadly stable and within the company’s target range. The Capex-to-Revenue ratio improved to 17.1 percent.
TIM also strengthened its leadership in 5G rollout, becoming the first operator to cover 1,000 cities with 5G services in Brazil as of October 2025.
Outlook
TIM’s results highlight the resilience of its mobile business, improving efficiency in capital allocation, and continued investment in next-generation networks as the company focuses on sustained growth in Brazil’s telecom market.
