Azul Successfully Emerges from its Comprehensive Restructuring Process and Reports Outstanding 4Q25 Results

São Paulo, March 27, 2026 – Azul S.A., “Azul” (B3:AZUL53, OTC:AZLUY), the largest airline in Brazil by number of cities served, announces today its results for the fourth quarter of 2025 (“4Q25”).

¹ Operating results were adjusted for non-recurring items totaling R$782.9 million in 4Q25. For more information see page 9.

4Q25 EBITDA reached an all-time record of R$2,138.2 million, increasing 9.6% year-over-year, representing a 36.9% margin. Operating income also hit an all-time record of R$1,420.3 million, increasing 14.7% and delivering a 24.5% margin.

Operating revenue reached R$5.8 billion, a 4.6% year-over-year increase, supported by a consistently strong demand environment, strategic network adjustments, and the solid performance of our beyond-the-metal business units and ancillary revenues.

RASK reached a record at R$46.55 cents in 4Q25, up 3.5% year-over-year, even with capacity growth. Our business units continued to make meaningful contributions to our revenues, accounting for 21.0% of RASK in the quarter.

Capacity grew 1.1% year-over-year, driven primarily by an 11.8% increase in international operations. In the quarter, Azul transported 8 million passengers, in line with the same period last year. Passenger traffic measured in RPKs increased 2.1%, outpacing capacity growth and pushing load factor to a record 85.0%, 0.8 percentage points higher than in 4Q24.

CASK in 4Q25 was R$35.15 cents, up 0.6% compared to 4Q24, mainly due to 4.3% annual inflation, a 1.5% increase in fuel price, and the increase in the number of legal claims related to irregular operations, partially offset by a 7.7% average appreciation of the Brazilian real, as well as several cost-reduction strategies already implemented as part of our restructuring process. In 4Q25, productivity measured in ASKs per FTE increased an impressive 5.7%, and fuel consumption per ASK dropped 1.3% year-over-year.

§ Cash plus receivables was R$3.7 billion, up 22.4% versus 4Q24, representing 17.1% of the last twelve months’ revenues. In October, Azul accessed US$221 million of its US$1.6 billion DIP financing. Accounts receivable increased 53.4%, or R$947.4 million, from December 31, 2025, mainly driven by a deliberate strategic reduction in credit card receivable advances. As of December 31, 2025, Azul held almost R$2.0 billion in credit card receivables, representing an immediately accessible liquidity source.

In February 2026, Azul successfully completed its U.S. Chapter 11 restructuring process, significantly strengthening its balance sheet, improving liquidity and cash generation, and materially reducing debt. Following emergence, the company’s net leverage stood below 2.5x (based on 2025 EBITDA and February 2026 net debt), positioning Azul for long-term sustainability and growth.

Management Comments

We closed 2025 with another quarter of solid financial and operational performance, with a number of all-time records. These results highlight the positive outcome of our Chapter 11 restructuring, concluded in less than nine months as announced in our recent Material Fact dated February 20, 2026.This milestone was only possible because we entered the process already supported by Restructuring Support Agreements with key stakeholders, including existing bondholders, our largest lessor AerCap, and our strategic partners.

Through this comprehensive restructuring effort, we positioned Azul for long-term sustainable growth and significantly increased our financial resilience. With the support of our main stakeholders, including aircraft lessors, bondholders, and our strategic partners, Azul considerably strengthened its balance sheet, emerging with a net leverage ratio below 2.5x, mainly driven by the reduction of approximately R$6.7 billion in loans and financing and a reduction of more than R$9.8 billion in aircraft lease liabilities versus 2024.

More importantly, during this comprehensive restructuring, we were able to reduce our annual interest payments by 50% and our recurring lease payments by more than 30%, positioning us for sustainable cash flow generation and a continued deleveraging process.

We also increased our liquidity through the successful issuance of US$1.375 billion in Senior Notes – which was over 7x subscribed – and through equity issuances of US$850 million, providing a solid liquidity position upon emergence, with an additional US$100 milion to come upon regulatory approval.

Turning to our 4Q25 results, we reported another quarter of strong performance, reflecting disciplined execution of our business plan. Total revenue reached an all-time record, supported by healthy demand, effective pricing actions, and solid contributions from our beyond-the-metal business units.

EBITDA expanded to an all-time record of R$2.1 billion in the quarter with a margin of 36.9%, confirming once again our industry-leading profitability.

Our business units Azul Fidelidade, Azul Cargo, and Azul Viagens once again delivered outstanding performances and remain key drivers of diversification and incremental profitability. Each unit continued to grow double digits year-over-year, contributing meaningfully to our total revenue and EBITDA.

With the restructuring successfully completed, we enter 2026 better prepared than ever. With our improved balance sheet, disciplined capacity growth, and unique network – 80% of our routes have no direct competition – Azul has a meaningful ability to react to macroeconomic challenges such as the recent increase in fuel prices. We are diligently pursuing a number of operational actions to mitigate this increase and ensure Azul is the long-term winner in the region.

Our hubs are the most corporate-oriented in Brazil, our business units deliver the strongest premium spend in the market, and our entire fleet is covered under power-by-the-hour agreements, providing predictability in engine maintenance costs. With one of the lowest future aircraft commitments in the region and a world-class balance sheet, Azul is exposed to lower financial and operational risk than peers, who face significantly higher challenges with a higher committed growth, which hinder passing through operational cost increases, higher international exposure, and materially larger upcoming debt obligations.

We are extremely confident about the new Azul prospects. I would like to thank our customers, crew members, partners, creditors, and investors for their trust and support throughout this important phase, and we look forward to implementing our plan to deliver results which will create long-term value for all stakeholders.

John Rodgerson, CEO of Azul S.A.

Recent Developments

On February 20, Azul announced the successful completion of its financial restructuring, a process designed to transform the Company’s capital structure through substantial deleveraging and enhanced cash generation.

We commenced the restructuring process with the support or four key creditors, including holders of our debt securities, our largest aircraft lessor AerCap, and strategic investors. The main outcomes of the process are summarized below:

Reduction of loans and financing by approximately RS$6.7 billion

Reduction of aircraft lease liabilities by nearly 46%

Estimated reduction of more than 50% in annual interest payments compared to pre-Chapter 11 capital structure

Estimated reduction of approximately one third in recurring aircraft leasing expenses

Capital raise of US$1.375 billion through the issuance of Senior Notes, with the transaction strongly supported by investors and demand more than 7x the original target amount

US$950 million in equity commitments, of which US$850 million have already been funded

Leverage of less than 2.5x in February 2026 upon emergence and implementation of the plan of reorganization (based on 2025 EBITDA and February 2026 net debt)

Below we present our illustrative post-restructuring position of loans, financing and lease liabilities reflecting the effects of the implementation of the restructuring in 1Q26:

Also, the transactions described herein enable Azul to significantly increase its cash generation by reducing its interest and lease payments by more than and estimated US$400 million in 2026 and beyond, as demonstrated below:

As a result of the restructuring, Azul’s new share capital amounts to R$21.8 billion, divided into 54,730,851,778,811 registered common shares (which number of common shares does not reflect the implementation of the 150,000 to 1 common share reverse share split approved by our shareholders on March 25, 2026 and expected to be implemented by April 20, 2026).

Operating Revenue

In 4Q25, Azul’s total operating revenues increased R$254.4 million, reaching an all-time record of R$5.8 billion, 4.6% higher than 4Q24 mainly due to a healthy demand environment, robust ancillary revenues and the notable performance of our businesses units.

Cargo revenue and other totaled R$459.2 million, 14.5% higher than 4Q24, mainly due to better performance in our domestic cargo operation. In 4Q25, domestic cargo revenues increased significantly, with 24% year-over-year growth, with healthy margins.

Even with a capacity increase of 1.1%, our RASK and PRASK were at a record levels for a fourth quarter at R$46.55 cents and R$42.86 cents respectively, due to the sustainable competitive advantages of our unique business model. In 4Q25, our beyond-the-metal business units accounted for 21.0% of RASK.

Operating Expenses

In 4Q25, operating expenses totaled R$4.4 billion, 1.7% higher than 4Q24. Costs per ASK (CASK) increased 0.6% to R$35.15 cents mainly explained by a 4.3% inflation in the period, a 51.5% increase in legal claims related to irregular operations that occurred mostly in 2024, and a 11.8% increase in international capacity, which have higher rates, partially offset by a 7.7% appreciation of the Brazilian real against the US dollar and higher productivity and cost-saving initiatives.

The breakdown of our main operating expenses compared to 4Q24 is as follows:

Aircraft fuel increased 1.2% to R$1,379.4 million mostly due to a 1.5% increase in fuel price per liter (excluding hedges), and a 1.1% increase in total capacity, partially offset by a reduction of 1.3% in fuel burn per ASK as a result of the growth in our next-generation fleet.

Salaries and benefits reduced 16.5% or R$122.6 million compared to 4Q24, mainly driven by a 8.8% reduction in departures and higher productivity, with a decrease of 7.4% in FTEs per aircraft.

Depreciation and amortization increased 0.8% or R$6.0 million, driven by the increase in the size of our E2 fleet compared to 4Q24 as a result of our fleet transformation process.

Other rent & ACMI increased R$64.3 million compared to 4Q24, mainly impacted by the start of our ACMI partnership in December 2024 which was implemented to offset the temporary reduction in our international capacity.

Airport fees increased 0.4% or R$1.1 million driven by the 11.8% increase in international capacity, which have higher rates denominated in foreign currency.

Traffic and customer servicing reduced 2.3% or R$5.5 million, primarily due to the optimization of our onboard services. On a per-ASK basis, traffic and customer servicing reduced 3.3%.

Sales and marketing reduced 2.3% or R$5.8 million, mostly driven by the shift to a lower capacity growth strategy. On a per-ASK basis, sales and marketing decreased 3.3%.

Maintenance and repairs reduced 8.8% compared to 4Q24, mainly due to the lower maintenance events related to rejected aircraft, in addition to savings from insourcing of maintenance events and renegotiations with suppliers and the 7.7% appreciation of the Brazilian real against the US dollar. Maintenance and repairs per ASK decreased 9.8%.

Net financial expenses were R$1,845.7 million in the quarter, mainly due to a R$643.5 million in interest on loans and financing accrued in 4Q25, and R$626.6 million in accrued interest related to leases recognized as financial expense as determined by IFRS16 rules.

Derivative financial instruments, net were almost zero in 4Q25. As of December 31, 2025, Azul had hedged approximately 3% of its expected fuel consumption for the next twelve months by using forward contracts, options, and pre-determined pricing agreements with our fuel suppliers.

Foreign currency exchange, net registered a net loss of R$1,231.5 million in 4Q25 due to the 3.5% end of period depreciation of the Brazilian real against the US dollar versus 3Q25, resulting in a decrease in lease liabilities and loans denominated in foreign currency.

Non-Recurring Items Reconciliation

The operating results presented in this release include items that we deem non-recurring and that should not be considered when making comparisons to prior or future periods.

In 4Q25, our operating results were adjusted for non-recurring items totaling R$782.9 million mainly related to:

Passenger revenue: R$233.3 million impact mainly driven by a prospective update of point-redemption estimates due to changes in customer behavior aligned with our business strategy in accordance with IFRS 15.

Salaries and benefits: R$12.2 million due to payroll expenses related to the restructuring process.

Other rent and ACMI: R$75.8 million in spare engine costs due to OEM contract suspension as part of our restructuring process.

Airport fees: R$0.2 million due to parking fees for rejected aircraft.

Sales and marketing: R$24.5 million write-off recognized during the restructuring process.

Maintenance and repairs: R$23.5 million maintenance costs related to aircraft rejected.

Other: R$1,152 million in net gains primarily associated with the R$1,725 million gain on the write-off of liabilities based on the best expectations and information available related to the agreement with the Unsecured Creditors' Committee, and a R$719.0 million gain related to lease modifications due to rejected aircraft and new lease terms, which were partially offset by R$1,292 million restructuring advisor fees and other costs related to the restructuring process.

The table below provides a reconciliation of our reported amounts to the adjusted amounts excluding non-recurrent items:

¹ Managerial View reclassifications set forth above represent presentation-only changes within income statement and cash flow statement line items and do not affect Azul’s financial statements prepared in accordance with IFRS. The Managerial View is presented with the objective of facilitating the understanding of the underlying operations in relation to the reclassifications presented above. Azul’s IFRS consolidated financial statements remain the sole basis for statutory reporting. The Managerial View line items are derived exclusively from Azul’s IFRS consolidated financial statements and are constructed through a defined set of operational reclassifications.

² Non-cash EBITDA items include R$3.6 billion non-cash write-off of lease liability and associated provisions related to lease rejections and other negotiations, partially offset by (i) R$842.1 million related to other provisions and (ii) R$0.66 million in stock-based compensation.

³ Non-EBITDA cash items include other costs of financial transactions, partially offset by foreign exchange gains realized in the quarter.

Reclassifications

§ Advances: managerial view separates out advances in credit card receivables from normal-course changes in accounts receivable for improved investor visibility.

Leases: managerial view incorporates the interest component of both operating and finance lease payments as well as the principal component of finance lease payments, in addition to any security deposits paid in the quarter.

Capex: managerial view moves capex items recognized in financing activities (financed capex) and in working capital (such as maintenance reserves and pre-payments to suppliers) into the capex line.

Fourth Quarter

Results

2025

Non-recurring items impacting EBITDA in the period totaled R$ 782.9 million. Of this amount, R$296.3 million was paid in the period and is related to advisors’ fees in connection with our Chapter 11 proceedings, and R$1,414 million was adjusted against working capital. Please see page 9 for detailed information on each non-recurring item adjusting EBITDA in the period.

Non-recurring items that do not impact EBITDA in the period totaled R$267.9 million:

Change in Working Capital in Managerial View was adjusted by R$156.1 million in 4Q25, mainly due to the following adjustments:

Deferred Airport & Landing Fees: Azul paid R$67.8 million in 4Q25 related to out-of-period amounts that were negotiated to be rolled over and paid in this quarter.

Tax Transaction: Azul paid R$2.4 million in the quarter related to a government tax settlement.

Others: Azul paid R$85.7 million in the quarter for other suppliers from previous periods that were negotiated to be paid this quarter.

Capex: Azul paid R$86.0 million of deferred capitalized maintenance in 4Q25 for services that were completed in prior periods and were negotiated to be postponed.

Leases: Azul made R$25.9 million in deferred rent payments during 4Q25, related to prior forbearance agreements with lessors, finalized once both parties completed the restructuring of the Company’s lease terms.

Liquidity and Financing

Azul ended the fourth quarter with Immediate Liquidity of R$3.7 billion, representing 17.1% of our LTM revenues. In October, Azul accessed US$221 million as the last tranche of its US$1.6 billion DIP financing.

Accounts receivable rose 53.4%, or R$947.4 million, compared to December 31, 2024, driven mainly by a deliberate strategic decision to not advance the totality of available credit card receivables. In Brazil, these receivables are predominantly tied to tickets already flown, eliminating cardholder credit risk and allowing for immediate access to funds without holdbacks. This structure provides Azul with significant liquidity flexibility, as receivables can be advanced at minimal cost when needed.

As of December 31, 2025, the Company had credit card receivables of R$1,976 million (R$740.6 million at December 31, 2024). In 4Q25, Azul advanced R$2,336 million in face value of credit card receivables (R$2,539 million for 4Q24), which were derecognized from the accounts receivable on the balance sheet and incurred interest costs of R$49.5 million under financial expenses (R$83.4 million for 4Q24), representing an average cost of 1.3% per month on the advanced amount. The year-over-year decrease in advanced credit card receivables was driven by the Company’s strategic decision to reduce advancing receivables under the 2025 business plan.

Compared to 3Q25, gross debt reduced R$1,544.6 million to R$35,770.7 million, mostly due to the roughly R$4.3 billion reduction on lease liabilities and other aircraft-related items as a result of the successful

implementation of the restructuring plan, partially offset by the R$2.7 billion increase on loans and financing due to the last DIP tranche accessed in the quarter, the interest accrued and not paid in the period and the 3.5% end of period depreciation of the Brazilian real against the US dollar, which increased our dollar-denominated lease liabilities and loans.

Excluding lease liabilities that were extinguished and loans and financing that were equitized in 1Q26, our gross debt would have been around R$21 billion.

As of December 31, 2025, Azul’s average debt maturity excluding lease liabilities and convertible debentures was 1.6 years, with an average interest rate of 13.4%. Average interest rate on local and dollar-denominated obligations were equivalent to CDI + 4% and 13.2% respectively. As of February 28, 2026 Azul’s average debt maturity was 4.7 years, with an average interest rate of 8.9%.

Azul’s leverage ratio measured as net debt to LTM EBITDA was 4.8x. This leverage does not consider the conversion of the 1L and 2Ls into equity as part of the Chapter 11 plan, in addition to the DIP repayment by the sources of the exit financing which reduced our leverage to less than 2.5x at emergence in February 2026.

Reclassifications: Under IFRS 16, only principal payments for operating leases are classified as “Leases” under cash flow from financing activities. Managerial View incorporates the interest component of operating and financing leases of R$74.1 million, finance lease payments of R$81.7 million captured in debt repayments, as well as security deposits of R$78.0 million captured under change in working capital under IFRS.

Non-Recurring: After filing for Chapter 11 in May 2025, Azul suspended payment on certain leases until restructuring terms were finalized. During the process, Azul reached agreements with lessors and paid previously suspended rent. Managerial View removes the impact of out-of-period cash rent payments made which totaled R$25.9 million in the quarter.

Capex

Capital expenditures as presented in our cash flows from investing activities excluding short-term investment and net of sale and leaseback totaled R$264.4 million in 4Q25, mostly due to the capitalization of engine overhauls and the acquisition of spare parts in the quarter. This does not include prepayments and maintenance reserves.

4Q25 Managerial capex totaled R$479.4 million, driven by the reclassification of a R$291.2 million related to prepayments and maintenance reserves that according to IFRS were recognized as change in working capital, and the engine financed amounts which impacted debt repayment and interest in the amount of R$56.1 million. Managerial capex was reduced by R$46.2 million related to redelivery and pre-delivery payments reflected as growth capex and R$86.0 million related to payments made in the quarter related to prior period, as demonstrated below:

Reclassifications: Certain items Azul views as capex are recognized in working capital, interest and financing activities under IFRS. Managerial View demonstrates these items as capex. In 4Q25, these items included:

R$193.2 million prepaid maintenance payments reclassified from change in other assets and change in accounts payable to capex

R$23.8 million related to interest on engine maintenance financing reclassified from interest paid to capex
