NOTICE TO THE MARKET

Fitch has affirmed TIM S.A.’s National Long-Term Rating at ‘AAA(bra)’; Outlook Stable.

TIM S.A. ("TSA" or “Company”) (B3: TIMS3; NYSE: TIMB), informs its shareholders, the market in general and other interested parties that, on this date, the credit rating agency Fitch Ratings (“Fitch”) has affirmed to the Company the National Long-Term Rating at ‘AAA(bra)’, with a Stable Outlook.

In Fitch's view, TIM's rating reflects its strong business profile, supported by its relevant participation in the mobile telephony sector, as well as the Company’s conservative financial metrics, with reduced financial leverage and robust liquidity position. The analysis also incorporates the expectation that TIM will report solid pre-dividend free cash flow over the next five years, supported by growth in its post-paid customer base and average revenue per user (ARPU).

The Stable Outlook is based on Fitch's projection that net leverage will remain below 1.0x and TIM's operating cash flows remains solid, enabling strong dividend distributions to service TIM Brasil's debenture.

The original Fitch’s note is available for access here.
