Material Fact

GOL Announces Filing of Form 15F to Deregister in The United States Under the Securities Exchange Act of 1934

São Paulo, February 26, 2025 – GOL Linhas Aéreas Inteligentes S.A. (B3: GOLL4) (“Company” or “GOL”), one of the leading airlines in Brazil, hereby informs, in accordance with Section 157, paragraph 4, of the Brazilian Law No. 6,404/1976 and the Brazilian Securities Commission (Comissão de Valores Mobiliários or the “CVM”) Resolution No. 44/2021, that the Company has filed today a Form 15F with the U.S. Securities and Exchange Commission (“SEC”) to terminate the registration of its preferred shares and American Depositary Shares (“ADSs”) under Section 12(g) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as well as to terminate its reporting obligations under the Exchange Act. As a result of filing Form 15F, GOL’s obligations to file reports under the Exchange Act have been suspended and are expected to terminate 90 days after the filing, barring any objection by the SEC.

GOL has also initiated the termination process of the ADS program relating to its preferred shares by delivering a termination notice to The Bank of New York Mellon under the terms of the deposit agreement governing the ADS program. As previously informed, as a result of GOL’s Chapter 11 filing, the New York Stock Exchange (“NYSE”) suspended the trading of GOL’s ADSs on January 26, 2024 and removed GOL’s ADSs from listing and registration on the NYSE at the opening of business on February 9, 2024.

GOL will maintain its registration as a publicly-held company with the CVM, as well as its listing and the admission of its preferred shares to trading on the São Paulo Stock Exchange (B3 S.A. - Bolsa, Brasil, Balcão) under the ticker symbol “GOLL4,” and it will continue to be subject to applicable disclosure requirements under Brazilian laws and regulations. GOL intends to continue to disclose its periodic reports, annual and interim results and communications as required by applicable laws and regulations on its website (www.voegol.com.br/ir), including in English.

GOL reserves the right, for any reason, to withdraw the filing of the Form 15F prior to effectiveness, and to otherwise change its plans in respect of SEC deregistration and termination of its reporting obligations under applicable U.S. federal securities laws in any way.
