In this way for the IBBC, IBEP, IBOV, IBXL and IVBX indices, the final volume of CPLE3 will be 1,671,982,390 shares; for the IBRA, IBXX, IGCT, MLCX and UTIL indices it will be 2,965,556,720 shares; for the IBBE index it will be 3,082,715,586 shares; for the IBBR index it will be 1,904,589,303 shares; for the IBEW index it will be 2,211,262,770 shares; for the IBLV index it will be 3,354,736,792 shares; for the IBSD index it will be 2,971,925,361 shares; for the ICO2 index it will be 983,045,676 shares; for the IDVR index it will be 936,183,248 shares; for the IEEX index it will be 20,600 shares: for the IGCX index it will be  5,937,369,440 shares; for the ISEE index it will be 1,527,752,924 shares; and for the ITAG index it will be 2,968,684,720 shares, in accordance with the respective methodologies.

2. With the migration of the governance level from Nivel 2 to the Novo Mercado, the Company will fall within the remit of the methodology of the Novo Mercado Corporate Governance Equity Index (IGNM) and will be included as of the opening of December 22, 2025 with a final volume of 2,965,556,720 ordinary shares and a readjustment to the divisor.
