ISA Energia (ISAE4) approved, in July 2026, a primary public offering of 44,444,444 preferred, registered, book-entry shares with no par value, at a price of R$ 27.00 per share, totaling R$ 1,199,999,988. The transaction, automatically registered with the CVM, involves only newly issued preferred shares.
The initial amount offered was increased by 100%, with the inclusion of 22,222,222 additional preferred shares under the same terms and price, to meet additional demand identified during the bookbuilding process. There was no distribution of an over-allotment option, and there will be no price stabilization procedure after the offering.
The shares from the offering will begin trading on B3 on July 27, 2026, with physical and financial settlement scheduled for July 28, 2026. The transaction is intended for professional investors, and current shareholders are guaranteed preemptive rights through a priority offering, but the controlling shareholder ISA Capital do Brasil S.A. will not participate in this priority subscription.
The capital increase will only be effected if an Extraordinary General Meeting, called for July 24, 2026, approves a new authorized capital limit and the ability to issue common and preferred shares without observing the current ratio between them. If the meeting does not approve the new limit, the offering will be canceled and all amounts deposited by shareholders and professional investors will be fully refunded within a maximum of three business days, without interest or monetary adjustment and net of applicable taxes.
The company, the members of the board of directors, the executive officers and ISA Capital do Brasil S.A. have entered into lock-up commitments, under which they undertake, for 90 days from the publication of the offering launch announcement, not to trade ISA Energia preferred shares or securities that are convertible, exchangeable or exercisable into preferred shares, subject to the exceptions set out in the offering documents.
