Ref.: Official Letter no. 30/2023/CVM/SEP/GEA-1Request for clarification on news

Dear Sirs,

Light S.A. (the "Company" or "Light") hereby clarifies as follows, in compliance with the Official Letter no. 30/2023/CVM/SEP/GEA-1 ("Official Letter"), as transcribed below.

"Subject Matter: Clarifications request regarding the news Dear Officer,

1. We refer to the news published on this date in the newspaper O Globo, Economy section, under the title: "Light says it has no revenue to run the concession until 2026", which contains the following statements: "Light, the energy distributor that serves the Metropolitan Region of Rio de Janeiro, said in a letter to the National Agency of Electrical Energy (Aneel) that its concession 'has presented insufficient cash generation to ensure its sustainability'. The main reason, according to Light, are the so-called'non-technical' losses, that is, thefts (gatos) and delinquency. The concession owned by Light has presented insufficient cash generation to ensure its sustainability, and the difference between real energy losses and regulatory losses defined by Aneel is one of the main factors causing this imbalance," says the document, sent to the agency this week and to which O Globo had access."
2. In light of the aforementioned, we request a statement on the veracity of the news article and, if confirmed to be true, we request explanations on the reasons why you understood it should not have been treated as a material fact, as well as to provide additional information that it may deem relevant on the matter.
3. 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 the Company 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, shall be responsible for imposing a penalty, without prejudice to other administrative sanctions, in the amount of R$1,000.00 (one thousand reais) for failure to comply with the requirements contained in this official letter, which must be responded exclusively by email until by 09.02.2023."

The Company clarifies that the document referred to in the above-mentioned news was submitted to the National Electric Energy Agency ("ANEEL") in the scope of the tariff adjustment processing for the year 2023, being, in this context, subject to confidentiality, and therefore of restricted access, in accordance with the provisions of Law No. 12,527/2011 and Decree No. 7,724/2012. In any case, the reasons underlying the Company's claims to ANEEL contained in the above correspondence are based on information already widely disclosed and, therefore, known by ANEEL itself, the Company's shareholders and the market in general.

These are, primarily, the impacts on the Company's cash generation due to significant nontechnical losses and payments' default of part of its consumer base, in addition to other market factors nonrelated to the concession, but that also affected the level of electric energy consumption and related payment compliance.

The existence and effects arising from the mentioned non-technical losses and customer defaults are continually reported by the Company in all tariff review procedures before ANEEL over the course of its concession's history, with the purpose of adjusting the recognition of these losses in a way consistent with the regulatory structure expected for a concession of power distribution services.

Additionally, the Company had also periodically disclosed information in this respect in its quarterly financial statements and results.
