Material Fact November | 2025 Azul Enters into Agreement with Unsecured Creditors Committee and Updates the Market on the Progress of
its Chapter 11 Proceedings São Paulo, November 1, 2025 – Azul S.A. ("Azul" or the "Company") (B3: AZUL4; OTC: AZULQ) announces
that it has entered into an agreement with the Official Committee of Unsecured Creditors (the “Committee”), appointed by the
Office of the United States Trustee in connection with the Chapter 11 proceedings, and the ad hoc group of secured noteholders (the “Secured
Ad Hoc Group”). The agreement provides for the Committee’s support of the Company’s plan of reorganization (the “Plan”)
and, among other terms, contemplates creditors classified under the Plan as General Unsecured Creditors receiving, at their option, either
their pro rata (a) share of up to US$20 million or (b) interest in a trust established under the Plan for the benefit of unsecured creditors
(the “GUC Trust”), to which the Company has committed to contribute: (i) warrants struck at an equity value of US$3.8 billion
for up to 5.5% of the Company’s equity upon emergence from the restructuring; (ii) rights for the GUC Trust to receive three annual
payments of up to US$6.5 million each, contingent upon the Company achieving certain financial performance targets at the end of 2027,
2028, and 2029; and (iii) between US$2.5 million and US$5 million for the payment of certain trustee and administrative expenses, in each
case, as more fully set forth in, and in accordance with, the terms of the Plan. The quantum of warrants contributed by the Company to
the GUC Trust will be reduced to the extent General Unsecured Creditors receive a cash recovery in lieu of interests in the GUC Trust.
The agreement also provides for the establishment of a convenience class under the Plan. Additional information regarding the agreement
is available at https://cases.stretto.com/Azul. The Company believes that entering into this agreement represents a significant milestone
toward the successful completion of its restructuring process. It marks an important step in achieving a consensual and orderly resolution
that preserves operations, strengthens the Company’s capital structure, and delivers sustainable value to all stakeholders. Furthermore,
the Company announces that it has filed with the United States Bankruptcy Court for the Southern District of New York (“Court”)
a revised version of the plan of reorganization (“Plan”) in the Chapter 11 proceedings. This step is aligned with the Restructuring
Support Agreements (“RSAs”) entered into on May 28, 2025, with financial creditors holding debt securities issued by the Company
and other significant strategic partners. The Company has also filed with the Court a revised version of the disclosure statement (“Disclosure
Statement”) summarizing the Plan, including information regarding the treatment of the various classes of the Company’s creditors
under the Plan, as well as other information related to Azul and the Plan. The primary purpose of the Disclosure Statement is to enable
Azul’s creditors entitled to vote on the Plan to make an informed decision regarding its acceptance or rejection. In this regard,
the Company clarifies that the numbers and information contained in the Disclosure Statement shall not be construed, interpreted, or used
as projections, guidance, targets, or performance commitments of the Company, nor do they constitute investment recommendations or materials
for investment decision-making purposes. The Disclosure Statement has been prepared exclusively for purposes of the Chapter 11 proceedings,
and its content derives solely from the rules applicable to such proceedings. Accordingly, it shall not be disclosed, updated, or used
for any other purposes, including those provided for under the regulations issued by the Brazilian Securities and Exchange Commission
(Comissão de Valores Mobiliários – CVM). Communication and Transparency with the Market Azul will keep its shareholders,
customers, crew members, and the market informed of all material developments in the restructuring process, in full compliance with applicable
laws and regulations. Stakeholders seeking specific Material Fact November | 2025 information regarding the Company’s Chapter 11
