Dear Officer,

1. We make reference to the news published on 03.20.2023 at the Spacemoney's website, under the title: 'Light engages BMA to protect itself from short-term debts, says columnist', which contains the following statements:

Light (LIGT3) has engaged BMA to prepare a precautionary action to protect itself with respect to short-term debts, reported the blog of columnist Lauro Jardim, from the newspaper O Globo.

According to the research, this is a next step in the process of an attempted financial reorganization of the company that, in January, engaged the consulting firm Laplace to restructure its debts.

2. 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 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

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.

5. 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 03.24.2023."

With respect to the aforementioned news, we confirm that BMA - Barbosa, Müssnich, Aragão Advogados ("BMA") renders legal services to the Company on a regular basis and that it is currently engaged in the assessment of potential options and strategies aiming at improving the Company's capital structure.

The Company also clarifies that these potential options and strategies are still under analysis, and that no decision has been made to date.

Therefore, the Company understands that the news as described above would not constitute a case of disclosure of material fact, according to the current applicable legislation.

Finally, the Company 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.
