Cemig declares R$200M in Interest on Equity
Cemig approved accepting terms for a 30-year concession extension, with 210 days after ministry notice to execute the amendment.
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
CIG (Cemig) declared R$200 million in Interest on Equity (R$0.06991340114 gross per share), payable in two equal installments by June 30 and December 30, 2027. Wholly owned Cemig GT completed a R$1 billion debenture issuance at CDI + 0.62% p.a.; wholly owned Cemig D completed a R$2 billion issuance in two R$1 billion series at CDI + 0.73% p.a. and IPCA + 7.3500% p.a. Cemig guarantees both issuances, each rated AAA(bra) by Fitch.
