Azul Updates the Market on the Progress
of its Chapter 11 Proceedings
São Paulo, September 19th,
2025 – Azul S.A. ("Azul” or “Company”) (B3: AZUL4; OTC: AZULQ), in the context of its
Chapter 11 proceedings, a hearing was held today before the United States Bankruptcy Court for the Southern District of New York to evaluate
several motions filed by the Company. These motions seek, among other matters, to extend the exclusivity periods for filing and voting
on the reorganization plan, extend the deadline to assume or reject non-residential real estate leases, and approve procedures to optimize
the review and reconciliation of claims. The Company is also seeking approval for measures to maintain confidentiality and redact sensitive
information, authorization to amend, assume, or reject certain aircraft and engine lease agreements, as well as to enter into or amend
financing agreements with strategic counterparties. Additionally, the Company requested an expansion of the scope of services provided
by its independent auditors to support the reorganization process.
These motions, still subject to court approval, aim
to provide Azul with more time and flexibility to negotiate with stakeholders, align its fleet and financial obligations with its business
plan, optimize claims management, and protect sensitive information, thus supporting the ongoing reorganization process.
All documents related to the Chapter 11 proceedings
are available on the website managed by the Company’s claims administration agent, Stretto, Inc., at https://cases.stretto.com/Azul.

Azul will keep its shareholders, customers, crew members,
