Rio de Janeiro, May 20, 2026 - AXIA Energia S.A. ("**Company**"), further to the material facts disclosed on February 18, 2026 and April 1, 2026, and to the notices to shareholders disclosed on March 2, 2026, April 1, 2026 and May 5, 2026, hereby informs its shareholders, holders of American Depositary Shares ("**ADSs**") and the market in general that, on this date, B3 approved the Company's application for migration to the Novo Mercado ("**Migration to Novo Mercado**").

In this context, the Company presents below the schedules for the operationalization of the mandatory exchange of (i) all class "A1" preferred shares ("**PNA1**") and all class "B1" preferred shares ("**PNB1**") into common shares issued by the Company ("**ON**"), at a ratio of 1.1 ON share for each 1 PNA1 or PNB1 share, as applicable, and (ii) all class "B1" ADSs issued by Citibank, N.A., as depositary ("**<u>Depositary</u>**"), ("**PNB1 ADSs**") into common ADSs issued by the Depositary ("**ON ADSs**") at a ratio of 1.1 ON ADS for each PNB1 ADS, all in accordance with the approvals obtained at the meetings of the Company's shareholders held on April 1, 2026:

| &nbsp;&nbsp;06/08/2026 | &nbsp;&nbsp;Start of trading of post-exchange ON shares (and on the Novo Mercado) |
| &nbsp;&nbsp;06/10/2026 | &nbsp;&nbsp;Credit of ON shares to former holders of PNA1 and PNB1 |
| &nbsp;&nbsp;(\*) The dates set for future events are merely estimates and may be changed, postponed or brought forward, at the sole discretion of the Company, without prior notice. Any changes to the schedule will be disclosed, when applicable, by means of a notice or communication to be published on the *websites* of the Company, the CVM, B3 and EDGAR Next. | &nbsp;&nbsp;(\*) The dates set for future events are merely estimates and may be changed, postponed or brought forward, at the sole discretion of the Company, without prior notice.

Additionally, the Company clarifies that any fractional ON shares resulting from the exchange above will be grouped and sold by the Company through a stock exchange auction, and the net proceeds from such auction will be distributed proportionally to the shareholders holding the fractions. The Company will disclose a Notice to Shareholders in due course with the applicable procedures and deadlines.

For holders of PNB1 ADSs, the mandatory exchange will be processed automatically by the Depositary, according to the schedule below:

|:---|:---|
| &nbsp;&nbsp;**Date\*** | &nbsp;&nbsp;**Event / Note\*** |
| &nbsp;&nbsp;06/05/2026 | &nbsp;&nbsp;Last day of trading of PNB1 ADSs on the New York Stock Exchange (the "**NYSE**") |
| &nbsp;&nbsp;On or about 06/10/2026 | &nbsp;&nbsp;PNB1 ADSs are exchanged for ON ADSs |
| &nbsp;&nbsp;(\*) The dates set for future events are merely estimates and may be changed, postponed or brought forward, at the sole discretion of the Company, without prior notice. Any changes to the schedule will be disclosed, when applicable, by means of a notice or communication to be published on the *websites* of the Company, the CVM, B3 and EDGAR Next. | &nbsp;&nbsp;(\*) The dates set for future events are merely estimates and may be changed, postponed or brought forward, at the sole discretion of the Company, without prior notice.

---

Holders of PNB1 ADSs will not need to take any action for the mandatory exchange to be reflected in their positions. Upon completion of the exchange, holders of PNB1 ADSs will automatically become holders of ON ADSs at the ratio disclosed above.

Holders of PNB1 ADSs should note that: (i) any costs and fees charged by the Depositary, custodian institutions or brokers as a result of the exchange will be borne by the respective ADS holder, in accordance with the conditions established in each case and (ii) the timeframe for completion of the exchange of the Company's ADSs may differ from the timeframe applicable to the Company's shares traded on B3, due to differences in the Depositary's and NYSE's operational procedures.

No fractional ON ADSs will be issued as a result of the exchange. Cash in lieu of fractional entitlements to ON ADSs will be distributed at a rate based upon the net proceeds received by the Depositary for the sale of the aggregate of the fractional ON ADSs entitlements (net of applicable fees, expenses and taxes).

Holders of PNB1 ADSs are recommended to consult their respective brokers or custodians for specific information on the procedures applicable to the exchange.
