Are there any buy or sell transactions reported in TIMB's Form 3?

No buy or sell transactions are reported. The filing classifies all entries as holdings, with zero buys and zero sells in the transaction summary, indicating this is an initial disclosure of existing positions, not a record of recent trades.

When do the TIMB CFO's restricted shares vest according to the Form 3?

What does each restricted share represent in TIMB's Form 3 filing?

Each restricted share represents a contingent right to receive one common share, minus any shares withheld for taxes. This means, upon vesting, the CFO will receive common shares net of statutory withholding obligations tied to the award.

How much direct ownership does the TIMB CFO report in common shares?

The CFO reports direct ownership of 38,317 common shares of TIM S.A. This position is separate from her restricted share awards and reflects her current, fully issued and outstanding common stock holdings as of the filing’s reporting date.
