Insights

TIM S.A. posts broad-based growth, stronger cash flow and maintains a conservative balance sheet.

TIM S.A. shows balanced 1Q26 growth, with total net revenue up 6.5% to R$6,806 million. Mobile service revenue grew 5.6%, fixed revenue advanced 22.8%, and Ultrafibra broadband revenue increased 11.4%, indicating healthier performance in both consumer mobile and fiber.

Profitability remained resilient. Normalized EBITDA rose 6.6%, while normalized EBITDA-AL increased 7.8% with a 37.1% margin, helped by leases growing only 2.7% year over year. Normalized net income edged up 1.3% to R$821 million, reflecting stable bottom-line performance.

Cash generation is a relative bright spot. Operating cash flow reached R$1,169 million, up 16.8%, with OpCF margin improving to 17.2%. Capex was R$1.35 billion or 19.9% of net revenue. Leverage of 0.82x Net Debt/LTM EBITDA and -0.22x on an EBITDA-AL basis suggests ample financial flexibility, though the FISTEL TFF liability of R$4.6 billion remains a structural consideration.

Operating Cash Flow financial
"OperatingCashFlow(“OpCF")representsEBITDA-ALminusCapex."
Operating cash flow is the amount of money a company earns from its main business activities, like selling products or services. It shows how well the company can generate cash to pay bills, invest in growth, or return money to shareholders. This figure helps investors understand if the company’s core operations are healthy and sustainable.
FTTH financial
"99.5% Running on FTTHNetwork (Broadband Client Base, ‘000)"
Fiber to the home (FTTH) is a broadband delivery method that runs optical fiber directly from a network to individual residences, replacing slower copper or wireless links. Like replacing a narrow water pipe with a wide one, it provides much faster, more reliable internet and supports higher data use. Investors care because FTTH requires large upfront investment but can create stable recurring revenue, long-term customer lock-in, and a competitive edge in regions with growing data demand.

IoC financial
"IoCannouncementofR$390Mlnin1Q26belowtheR$690Mlnannouncedin1Q25."
An IOC (immediate-or-cancel) is a type of trade instruction that attempts to execute as much of an order as possible right away and automatically cancels any portion that cannot be filled immediately. For investors this controls how quickly a trade happens and how much of the order may be left unmet, similar to trying to grab as many available seats at a restaurant immediately and letting the rest go if they aren’t free right away — useful for managing price risk and liquidity.
