Sentiment and the balance of points
Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.
Rhea-AI Filing Summary
TIM S.A. is correcting the previously disclosed dividend amount per share while keeping the total dividend unchanged. The gross dividend per share was adjusted from R$0.7482883774 to R$0.7491354635, with the total distribution remaining at R$1,790,000,000.00. This higher per-share value results from an increase in treasury shares, which reduces the number of shares entitled to receive dividends.
The dividend will be paid by December 30, 2025, in the total amount of R$1.79 billion, without any monetary adjustment. Shareholders of record on December 19, 2025 are entitled to receive the dividend, and shares acquired after that date trade ex-dividend, meaning they do not carry the right to this distribution.

NOTICE TO SHAREHOLDERS
RECTIFICATION OF THE AMOUNT PER SHARE OF DIVIDENDS
TIM S.A. ("TIM" or "Company") (B3: TIMS3; NYSE: TIMB) informs its shareholders and the market in general that due to the change in the number of treasury shares in the period prior to December 19, 2025, there was a change in the gross amount per share announced in the Material Fact of December 16, 2025, as shown in the table below:
From:
| Gross value per share | Total Amount |
| 0.7482883774 | 1,790,000,000.00 |
To:
| Gross value per share | Total Amount |
| 0.7491354635 | 1,790,000,000.00 |
The gross amount per total share was increased by R$0.0008470861 in view of the increase in the number of treasury shares and, consequently, the decrease in the number of shares entitled to receive dividends.
The payment will take place until December 30, 2025 in the amount of R$1,790,000,000.00 (one billion, seven hundred and ninety million reais), without the application of any monetary adjustment index, with the date of December 19, 2025 being the date that will serve to identify the shareholders entitled to receive such amounts. Thus, the shares acquired after that date will be ex-right to distribute dividends.
Rio de Janeiro, December 26, 2025.
