Comunicado ao Mercado - CEMIG completa 26 anos no Índice Dow Jones Best in Class (DJ BIC)
Regulatory Filings Classification · 1% confidence The document is a brief market communication (“Comunicado ao Mercado”) announcing CEMIG’s inclusion in the Dow Jones Best in Class ESG index for the 26th consecutive year. It does not contain detailed financial results, management discussion, or any voting/dividend/share issuance information. It is not an ESG report itself (no detailed performance metrics), nor is it a formal regulatory filing like a 10-K, interim report, or audit report. It is a generic corporate announcement intended for the market, fitting the fallback category for miscellaneous regulatory announcements. Therefore, it is classified as a Regulatory Filing (RNS).
