TIM S.A. provides mobile connectivity across Brazil under the TIM brand. Individuals and businesses pay through monthly plans or prepaid credits for calls and mobile data, often bundled with digital content and subscriptions. Mobile services account for the vast majority of revenue; fixed broadband sold as TIM UltraFibra and equipment sales make smaller contributions.
The business depends on retaining paying customers and investing in network coverage and capacity to keep service reliable as data use grows. Its fiber-to-the-home expansion also relies on third-party network capacity. Brazilian regulator ANATEL sets coverage and service-quality requirements for its operating authorizations and requires TIM to offer roaming at regulated rates to certain mobile providers. Serious failures to meet authorization requirements can lead to sales restrictions or loss of permission to operate.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
TIM’s results depend chiefly on Brazilian mobile spending, customers moving to higher-value postpaid plans and pricing discipline among nationwide operators.
Telefônica Brasil’s Vivo competes with TIM for paying mobile and fixed-broadband customers in Brazil. Watch Vivo’s share of postpaid mobile connections—40.3% at December 31, 2025—as a measure of the competition TIM faces for higher-value plans.
América Móvil’s Claro competes directly with TIM for Brazilian customers paying for mobile services and fixed broadband. América Móvil also has substantial operations elsewhere, so its Brazilian business is the part to watch for competition with TIM.

América Móvil’s Brazilian business competes with TIM S.A. for mobile and broadband customers, so its report can show what those customers are doing.
Focus on service revenue and customer trends in América Móvil’s Brazilian business, not group totals that include other countries. Growing Brazilian service revenue with stable customers would suggest demand and spending support the services both companies sell; weaker revenue or customer trends would suggest TIM may find it harder to win the same mobile and broadband customers.

TIM S.A. earns most of its service revenue from mobile customers, and this report will show whether postpaid growth is offsetting prepaid losses.
Read total mobile connections, postpaid customers and mobile ARPU (average revenue per user) together. Rising postpaid customers and ARPU with total connections holding steady would show that customers moving to higher-value plans are lifting revenue; falling connections or weaker prepaid revenue would show that this growth is not replacing lost customers and spending.
