Ref.: Official Letter no. 123/2023/CVM/SEP/GEA-1Request for clarification on news

Dear Sirs,

Light S.A. ("Light"), in compliance with the Official Letter no. 123/2023/CVM/SEP/GEA-1 ("Official Letter"), as transcribed below, hereby clarifies as follows.

"Subject Matter: Request for clarification on news Dear Officer,

1. We refer to the news published on this date in the newspaper O Estado de São Paulo, Economia & Negócios section, under the title: 'Light is already designing a judicial reorganization format as a way out of the crisis', which contains the following statements:

Even though the judicial reorganization is prohibited for energy distributors, Light is already planning this way out, in case the ongoing mediation proceeding before the Court fails. There are already signs of resistance among creditors to this strategy, especially since it entails the suspension of collection of their debts.

1. In light of the aforementioned, we request a statement on the veracity of the news and, if confirmed to be true, we request explanations on the reasons why the company understood it should not have been treated as a material fact, as well as to provide additional information that the Company may deem relevant on the matter.
2. We highlight that, pursuant to Article 3 of CVM Resolution No. 44/21, the Investor Relations Officer is responsible for reporting to the CVM and, as applicable, to the stock exchange and organized over-the-counter market entities in which the company's securities are traded, any material facts or acts that occurred or are related to its business, as well as ensuring its wide and immediate dissemination, simultaneously in all markets where the Company's securities are admitted to trading.

1. The explanations must be sent through the Empresa.net System, category "Notice to the Market", type "Clarification on CVM/B3 inquiries", subject matter: News published on a media website, which shall include a transcription of this official letter. The compliance with this request for clarification through a Notice to the Market does not exempt from the responsibility for the untimely disclosure of a Material Fact, pursuant to CVM Instruction 44/21.
2. We also point out that, by order of the Superintendence of Corporate Relations, under its legal attributions, based on Article 9, item II of Law 6,385/76 and on CVM Resolution No. 47/21, a penalty in the amount of R$1,000.00 (one thousand reais) will be imposed, without prejudice to other administrative sanctions, for failure to comply with the requirements contained in this official letter, which has been sent exclusively by email, by 04.24.2023."

As it is already of public knowledge, there are currently ongoing activities within the scope of the mediation proceeding initiated due to the preliminary injunction granted on April 12, 2023, under the Motion for Precautionary Injunction ("Injunction") filed by Light, Light Serviços de Eletricidade S.A. ("Light SESA"), Light Energia S.A. ("Light Energia") and Lajes Energia S.A. ("Lajes Energia" and, jointly with Light, Light SESA and Light Energia, the "Companies").

The management's efforts are focused, at this moment, on interactions and negotiations with creditors in the context of the mediation, such that, if necessary, the adoption of any other alternatives or courses of action to implement the intended readjustment and/or equalization of the financial obligations covered by the Injunction will depend on the evolution and unfolding of the mediation proceeding.

As it was disclosed in the Notice to the Market released on April 13, 2023, all potential alternatives to implement the intended financial readjustment and/or financial equalization continue to be analyzed by the Companies, together with their advisors.

Light reaffirms that it will keep its shareholders and the market in general informed about relevant and significant aspects of its business, including those related to the abovementioned matter.

These are the clarifications we have in relation to the Official Letter, and we remain at your entire disposal for further clarifications.

Sincerely,

Eduardo Gotilla

Chief Financial and Investor Relations Officer
