Our passenger revenues are generally higher during the summer and winter holidays, in January and July respectively, and in the last two weeks of December, which corresponds to the holiday season. Considering the distribution of fixed costs, this seasonality tends to cause variations in operating results between the quarters of the fiscal year. It should be noted that the COVID-19 pandemic impacted the behavior related to the frequency of travels of the Company’s customers, in the first quarter of 2022 and 2021, thus impacting the accumulated result for the year presented for comparative purposes.

Net Working Capital and Capital Structure Abstract [Abstract]
Net Working Capital and Capital Structure	NET WORKING CAPITAL AND CAPITAL STRUCTURE 2.1 Contextualization Throughout the year ended December 31, 2023, the Company focused its efforts on executing the debt restructuring plan. Discussions with creditors began at the end of 2022, with the signing of agreements concentrated in the third and fourth quarters of 2023. The main actions taken in this process are presented in detail below, however, it is necessary to clarify the facts and conditions that led the Company to promote such restructuring: From the founding of the Company until the outbreak of the COVID-19 pandemic, Azul demonstrated through its results the strengths of its economic foundations. As an airline with a differentiated business strategy, supported by its regional routes, where there was very little or even no competition, until that moment the Company had shown exponential growth. As is generally known, in March 2020, the World Health Organization (“WHO”) classified the COVID-19 as a “public health emergency of international concern” and declared it a pandemic. From this moment, a sharp rupture was noted in the global economic activity, unleashing an unprecedented global economic crisis. It is worth remembering that the speed of spread and contagion of the disease have caused countries around the world, including Brazil, to adopt measures to recommend social distancing, travel restrictions and the closure of borders. As a consequence, the airline industry was one of the first and hardest hit in its operations and results. In order to face this absolutely challenging scenario, the Company, through its Executive Committee, started to monitor and establish operational and financial strategies to go through this period of crisis until the resumption of operations. Among the main actions to achieve the established strategies, the following stand out: 2.1.1 Resizing of the airline network One of the first and most important actions taken by Management in response to the economic crisis unleashed by the COVID-19 pandemic was the resizing of its airline network, with reductions in capacity that reached its peak in April 2020. At this moment, the volume of ASKs (seat-kilometers offered) offered in the domestic market accounted fo r only 13% of the volume of the same period of 2019, represented by approximately 70 daily flights, and in turn the demand reduced to 11% of the total of the previous year. Remembering that until then the Company operated almost 1,000 daily flights. This situation severely impacted the Company's ability to generate cash and be able to honor financial commitments made in the pre-pandemic period. 2.1.2 Cost reductions Faced with the difficulties imposed by the pandemic scenario, the Company adopted several measures to reduce its fixed and variable costs, including: (i) suspension of hiring, (ii) launch of unpaid leave and voluntary dismissal programs; (iii) reduction of salaries of executive committee members and directors; (iv) reduction of general salary expenses by around 65%, in the period between March and August 2020, and (v) collective agreement to reduce the working hours of pilots and flight attendants for 18 months. 2.1.3 Strengthening of cash Throughout the period, with the evolution of the pandemic, Management endeavored to keep the cash levels necessary to face the crisis, requiring reaching new agreements with suppliers, bank creditors and lessors, within this scope the main actions taken were: • access to the capital market through the issuance of debentures; • postponement of payment of profit sharing of 2019; • negotiation of new payment conditions with suppliers for cash preservation; • suspension of business travels and discretionary expenses; • negotiation to reduce airports fee; • agreement for postponement of delivery of aircraft model E2; • agreement with lessors with a reduction of approximately 77% of the cash outflow for the period between April and December 2020; • renegotiation of the conditions and maturities of debentures and obligations of FINAME; and • Issuance of debentures convertible into shares in the amount of R$ 1,745,900 (equivalent to US$323,195 ) with maturity in 5 years and interest of 7.5% p.a. in the first year and 6.0% p.a. from the second year onwards, with semi-annual settlements. 2.1.4 Scenario after the COVID-19 pandemic After the most critical moments due to the COVID-19 pandemic have passed, both the global and Brazilian economies are facing additional problems such as: • abrupt increases in oil prices that directly impact aircraft fuel costs; • significant devaluation of the Real against the US$; • growth in inflation rates in the most developed markets such as the United States and Europe; • shortage of credit, causing a significant increase in interest rates for raising funds; and • crisis in the supply chain of maintenance materials that puts adverse pressure on costs for the Company. Given this situation, Management, in December 2022, established a strategy to renegotiate all its debts, whose execution extended throughout 2023 due to the large number of stakeholders involved and the complexity of the topics under discussion, as follows: 2.1.4.1 Issuance of simple debentures In June 2023, the Board of Directors approved the issuance of simple debentures, non-convertible into shares, with security interest and additional personal guarantee, in a single series, from ALAB respectively, in the total amount of R$600,000; with a nominal unit value of R$1, rate equivalent to CDI 6.0% p.a. and maturity in June, 2024. The resources were fully and exclusively used to pay for aircraft fuel. 2.1.4.2 Issuance of debt securities 2028 – Senior notes 2028 In July 2023, the Company issued and priced a debt securities issue of R$3,831,040 (equivalent to US$800,000) in principal amount, with funding costs of R$187,658. Nominal interest corresponds to 11.9% p.a., and will be paid quarterly, in February, May, August and November of each year, starting on November 2023. The principal Senior Notes 2028 amount will mature in August 2028, unless redeemed or repurchased in advance and canceled in accordance with the terms of issuance, by the Company. In October 2023, the Company issued additional notes in the principal amount of R$186,005 (equivalent to US$36,778). Such notes were issued in exchange for the aggregate principal amount of R$190,819 (equivalent to US$37,730) of the Senior Notes 2024. In February 2024, the Company issued additional notes in the principal amount of R$740,585 (equivalent to US$148,700). Such notes were issuance to qualified institutional investors. 2.1.4.3 Debt securities exchange offers (“exchange offer”) In June 2023, the Company announced its subsidiary Azul Investments issued: • an offer exchange debt securities with interest of 5.9% p.a. due 2024 (Senior Notes 2024) for debt securities with interest of 11.5% p.a. due 2029, and • an offer to exchange debt securities with interest of 7.3% p.a. due 2026 (Senior Notes 2026) for debt securities with interest of 10.9% p.a. due 2030. In July and October 2023, the Company concluded its exchange offers and issued: • R$1,410,967 (equivalent US$294,215) in principal amount of 11.5% p.a. debt securities due 2029 (which were issued in exchange for R$1,410,967 (equivalent to US$294,215) of the aggregate principal amount of the Senior Notes 2024); • R$2,725,010 (equivalent to US$568,219) in the principal amount of 10.9% p.a. debt securities due 2030 (which were issued in exchange for R$2,725,166 (equivalent to US$568,252) of the aggregate principal amount of the Senior Notes 2026); and • R$186,005 (equivalent to US$36,778) in principal amount of 11.5% p.a. debt securities due 2028 (which were issued in exchange for R$190,819 (equivalent to US$37,730) of the aggregate principal amount of the Senior Notes 2024). In total, 90.0% of the principal amount of the Senior Notes 2024 and 2026 were exchanged for debt securities 2029 and 2030, as shown below: Description US$ % exchanged 5.9% Senior notes 2024 331,945 83.0 % 7.3% Senior notes 2026 568,252 94.7 % Total 900,197 90.0 % 2.1.4.4 Renegotiation of convertible debentures In July and August 2023, the Company and the debenture holders made changes to the original conditions of the convertible debenture debts. In summary: • Conversion Price: from R$32.26 to R$22.78 per preferred share; • Nominal interest rate: 6.0% p.a. to 12.3% p.a; and. • Maturity October 2025 to October 2028. The mandatory early redemption corresponds to R$542,496 (equivalent to US$108,900) and was determined as follows: • the redemption value of each eligible debenture was 120% of the updated nominal unit value of the debentures, that is, the updated nominal unit value of the debentures plus a premium of 20% on the aforementioned value; and • any and all interest and monetary updates incurred and not paid. 2.1.4.5 Renegotiation of lease obligations In March 2023, forbearance agreements were signed between the Company and its main lessors. Such contracts aimed to temporarily suspend payments related to aircraft leases, while new deadlines and methods for paying obligations were being negotiated, mainly deferrals negotiated during the COVID-19 pandemic, as well as the difference between the contractual leasing rates of Azul and current market rates. During the year ended December 31, 2023, the Company defined the renegotiation conditions and entered into definitive agreements with the lessors, who agreed to receive negotiable debt securities maturing in 2030 ("Notes") and debt with the possibility of settlement in Azul preferred shares or cash, at the Company's discretion ("Convertible to equity”) in order to reflect the Company's new cash generation, its improved capital structure and the reduction in its credit risk. Until December 31, 2023, the Company had renegotiated 119 lease contracts. In general, the conditions agreed between the Company and lessors are as follows: • Notes: R$1,385,115 (equivalent to US$286,014), with interest to be paid quarterly from December 2023, with interest of 7.5% p.a., and principal maturity in June 2030; and • Convertible to equity: R$2,178,740 (equivalent to US$450,032), and consecutive quarterly payments, starting in July 2024. The costs incurred in these renegotiations correspond to R$84,421 and were recorded in profit or loss, as required by IFRS 9 – Financial Instruments. 2.1.4.6 Renegotiation of obligations with accounts payable of aircraft services and parts Renegotiations with suppliers of aircraft services and parts mostly followed the same model as the renegotiation of lease obligations, that is, the Company issued: • Notes: R$408,541 (equivalent of US$84,386), with interest to be paid quarterly from December 2023, with interest of 7.5% p.a. and principal maturity in June 2030; and • Convertible to equity: R$159,775 (equivalent to US$33,002), with consecutive quarterly payments, starting in January 2025. 2.2 Net working capital and capital structure As of December 31, 2023, after the renegotiations, the Company's working capital and equity position are as shown below: December 31, December 31, Description 2023 2022 Variation 2021 Variation Net working capital (9,704,733) (10,184,169) 479,436 (5,863,917) (4,320,252) Equity (21,327,848) (19,007,500) (2,320,348) (18,333,003) (674,497) The variation in the balance of net working capital, which represents a reduction in the deficit of approximately 4.7%, is specifically a consequence of the debt restructuring actions presented in note 2.1.4. The increase in the negative position of equity is mainly due to the Company's negative financial result, which exceeded operating profit by R$2,380,456 for the year ended December 31, 2023. In view of the above, despite the increase in the negative equity position, Management assessed and concluded that the Company is capable of continuing its operations and fulfilling its obligations in accordance with the contracted maturities. This assessment is based on the Company's business plan approved by the Board of Directors in December 2023 and the entire liability restructuring process described in these financial statements. The Company's business plans include planned future actions, macroeconomic and aviation sector assumptions, such as level of demand for air transport with corresponding increase in traffic and fares, estimated exchange rates and fuel prices. The Company's Management monitors and informs the Board of Directors about performance in relation to the approved plan. Based on this conclusion, these consolidated financial statements were prepared based on the going concern principle. 2.3 Acceleration of fleet transformation In 2019, the Company’s Management approved the replacement plan for the Embraer E195 (“E1”) model aircraft. On the same date, the Company signed letters of intent to sublease a total of 54 aircraft and 4 engines to other airline operators (“operators”). The change in the intended use of the aircraft triggered a review to verify the recoverability of the assets (impairment), which resulted in the recognition of a loss of R$2,075,582 and the constitution of an onerous contract of R$821,751 at that time. Until December 31, 2022, there were partial reversals of provisions for impairment and onerous contracts, in the amount of R$1,102,791, corresponding to 46 aircraft and 4 engines, resulting from changes due to the economic consequences of the COVID-19 pandemic. Until December 31, 2023, there was a reversal of provisions for impairment, in the amount of R$245,636, resulting from the decision not to continue with plans to sublease the aircraft. It is worth remembering that these aircraft have never stopped being operated by the Company and will remain in use until the end of the lease contracts. 2.3.1 Breakdown of balances of provision of impairment and onerous contracts December 31, Description 2023 2022 Provision for impairment of right-of-use assets — (110,349) Provision for impairment of property and equipment (143,790) (279,077) Total provision for impairment of Company assets (143,790) (389,426) Total (143,790) (389,426) 2.3.2 Movement of the provision for impairment and onerous contracts Description Impairment of assets Onerous contracts Total At December 31, 2021 (912,154) (693,407) (1,605,561) Reversals 516,157 586,634 1,102,791 Consumption — 178,126 178,126 Interest incurred — (100,975) (100,975) Foreign currency exchange — 29,622 29,622 Transfers 6,571 — 6,571 At December 31, 2022 (389,426) — (389,426) Reversals 245,636 — 245,636 At December 31, 2023 (143,790) — (143,790)

Basis for preparation and presentation of the financial statements [Abstract]
DECLARATION OF MANAGEMENT, BASIS FOR PREPARATION AND PRESENTATION OF THE FINANCIAL STATEMENTS	DECLARATION OF MANAGEMENT, BASIS OF PREPARATION AND PRESENTATION OF THE CONSOLIDATED FINANCIAL STATEMENTS The Company’s consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (“IFRS”) issued by the International Accounting Standards Board (“IASB”). The Company’s consolidated financial statements have been prepared based on the real (“R$”) as the functional and presentation currency. All currencies shown are expressed in thousands unless otherwise noted. The Company operates mainly through its aircraft and other assets that support flight operations, making up its cash generating unit (CGU) and its only reportable segment: air transport. The preparation of the Company's consolidated financial statements requires Management to make judgments, use estimates and adopt assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. However, the uncertainty related to these judgments, assumptions and estimates can lead to results that require a significant adjustment to the carrying amount of assets, liabilities, revenue and expenses in future years. When preparing these consolidated financial statements of the Company, Management used the following disclosure criteria to understand the changes observed in the equity and in its performance, since the end of the last fiscal year ended December 31, 2022, disclosed on March 6, 2023: (i) regulatory requirements; (ii) relevance and specificity of the information on the operations; (iii) informational needs of users of the consolidated financial statements; and (iv) information from other entities participating in the passenger air transport market and cargo. Management confirms that all relevant information specific to the consolidated financial statements, is presented and corresponds to that used by Management when carrying out its business management activities. As a result of improvements made to the presentation of some items in the statement of financial position, statements of operations and of cash flow for the current year, the following changes in presentation were retrospectively adjusted for to ensure comparability of amounts in the previous periods: December 31, 2022 Statement of financial position As reported Reclassifications Reclassified Assets Prepaid expenses 182,891 (182,891) — Other assets 6,958 182,891 189,849 Non-current assets Prepaid expenses 319,000 (319,000) — Other assets 9,005 319,000 328,005 Liabilities and equity Current assets Loans and financing 1,127,729 (14,789) 1,112,940 Convertible debt instruments — 14,789 14,789 Insurance payable 84,985 (84,985) — Accounts payable 2,432,843 84,985 2,517,828 Reimbursement to customers 13,822 (13,822) — Other liabilities 68,851 13,822 82,673 Non-current assets Loans and financing 7,508,689 (1,388,930) 6,119,759 Convertible debt instruments — 1,388,930 1,388,930 Total 11,754,773 — 11,754,773 December 31, 2022 Statement of Operations As reported Reclassifications Reclassified Rental (203,398) 203,398 — Insurance (81,665) (21,551) (103,216) Other (1,857,578) (181,847) (2,039,425) (2,142,641) — (2,142,641) December 31, 2021 Statement of Operations As reported Reclassifications Reclassified Changes in operating assets and liabilities Insurance — (80,256) (80,256) Other (2,422,799) 80,256 (2,342,543) (2,422,799) — (2,422,799) December 31, 2022 Statement of Cash Flows As reported Reclassifications Reclassified Changes in operating assets and liabilities Prepaid expenses (274,563) 274,563 — Other assets 88,435 (274,563) (186,128) Insurance payable (1,404) 1,404 — Accounts payable 2,275,418 (1,404) 2,274,014 Reimbursement to customers (169,967) 169,967 — Other liabilities 40,948 (169,967) (129,019) Cash flows from investing activities Acquisition of property and equipment (1,252,532) 628,293 (624,239) Acquisition of capitalized maintenance — (628,293) (628,293) Total 706,335 — 706,335 December 31, 2021 Statement of Cash Flows As reported Reclassifications Reclassified Changes in operating assets and liabilities Prepaid expenses (364,107) 364,107 — Advances to suppliers (120,266) 33,330 (86,936) Other assets 79,201 (397,437) (318,236) Insurance payable 40,669 (40,669) — Accounts payable 1,078,643 40,669 1,119,312 Reimbursement to customers (63,507) 63,507 — Airports fees 80,788 (30,419) 50,369 Other liabilities 439,957 (33,088) 406,869 Government installment payment program (7,399) 7,399 — Taxes payable 66,719 (7,399) 59,320 Cash flows from investing activities Cash received in the sale and leaseback operation — 21,256 21,256 Cash flows from financing activities Proceeds from sale and leaseback 21,256 (21,256) — Total 1,251,954 — 1,251,954 The consolidated financial statements have been prepared on the historical cost basis, except for the following material items recognized in the statement of financial position: Fair value: • Short-term investments classified as cash and cash equivalents; • Short-term investments; • Derivative financial instruments; and • Debenture conversion right. 3.1.

Disclosure of changes in accounting estimates [abstract]
Significant accounting estimates	MATERIAL ACCOUNTING POLICIES The material accounting policies adopted by the Company are described in each corresponding explanatory note, except those that refer to more than one explanatory note, described below. The accounting policies have been consistently applied for the comparative years presented and for the Company’s consolidated financial statements. 4.1 Consolidation The consolidated financial statements include information about the Company and its subsidiaries in which held direct or indirect control. Control of a subsidiary is achieved when Company is exposed, or has rights, to variable returns in such subsidiaries and has the power to influence the investee's operating and financial decisions. The financial statements of the subsidiaries have been prepared using the same accounting policies as the Company. All assets, liabilities, equity, income and expenses related to transactions between related parties are eliminated in full in the consolidation process. 4.2 Impairment The Company performs an annual review for impairment indicators in order to assess events or changes in economic, technological, or operating conditions that may indicate that an asset is impaired. The recoverable amount of an asset or cash-generating unit is the higher of its fair value, less costs to sell and its value in use. When the carrying amount of an asset or cash-generating unit exceeds its recoverable amount, a provision for impairment is set up by adjusting the carrying amount. The previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine the asset's recoverable amount. The reversal is limited, so that the carrying amount of the asset does not exceed its recoverable amount, nor does it exceed the carrying amount previously determined, net of depreciation or amortization. In estimating the asset's value in use, estimated future cash flows are discounted to present value, using a pre-tax discount rate that reflects the weighted average cost of capital for the cash-generating unit. 4.3 Main accounting estimates As disclosed in explanatory note 3, Management makes judgments that have a significant effect on the amounts recognized in the consolidated financial statements, namely: Description Note Provision for impairment of aircraft and engines and onerous contracts 2.3 Provision for losses with maintenance reserves 11 Analysis of the recoverable value of goodwill and slots 17 Revenue from ticket breakage and loyalty programs 25 Provision for return of aircraft and engines 28.1.1 Provision for tax, civil, labor and other risks 28.1.2 The Company continually reviews the assumptions used in its accounting estimates. The effect of revisions to accounting estimates is recognized in the financial statements in the year in which such revisions are made. 4.4 New or amended accounting standards and principles effective in 2023 The following accounting standards came into force from January 1, 2023. Standard Amendment Impact IAS 8 Definition of accounting estimates Yes, but no changes IAS 1 and IFRS Practice statement 2 Disclosure of accounting policies Yes, but no changes IAS 12 Deferred Tax related to Assets and Liabilities arising from a Single Transaction Yes IAS 12 Pillar Two Model Rules No IFRS 17 Insurance contracts No 4.5 New or amended accounting standards and principles, effective from 2024 onwards The following accounting standards came into force on January 1, 2024 and, in Management's opinion, will not significantly impact the Company's statements of financial position or of operations. Standard Amendment IAS 1 Classification of liabilities as current and non-current and non-current liabilities with covenants IFRS 16 Lease liability in a sale and leaseback IAS 7 and IFRS 7 Disclosures: Supplier finance arrangements IAS 21 The effects of changes in exchange rates 4.6 Foreign currency transactions Foreign currency transactions are recorded at the exchange rate in effect at the date the transactions take place. Monetary assets and liabilities designated in foreign currency are determined based on the exchange rate in effect on the balance sheet date, and any difference resulting from currency conversion is recorded in the line “Foreign currency exchange, net” in the statement of operations for the year.

SHORT AND LONG-TERM INVESTMENTS	LONG-TERM INVESTMENTS 7.1 Accounting policies In the presentation and measurement of financial investments, the Company considers the provisions of IFRS 9 – Financial Instruments, which determines that financial assets are initially measured at fair value less costs directly attributable to their acquisition. In turn, the subsequent measurement is divided into two categories: 7.1.1 Amortized cost Long-term investments are measured at amortized cost when all the following conditions are met: • The Company plans to hold the financial asset to collect cash flows set forth in contract; • Contractual cash flows represent solely payments of principal and interest (“SPPI”); and • The Company did not opt for the fair value methodology in order to eliminate measurement inconsistencies or an “accounting mismatch”. 7.1.2 Fair value • Through comprehensive income : short-term investments are measured at fair value through comprehensive income when both of the following conditions are met: (i) the Company plans to hold the financial asset to collect cash flows set forth in contract and sell the asset; and (ii) contractual cash flows represent SPPI. • Through profit or loss : it is considered to be a residual category, in other words, the Company does not plan to hold the financial asset to collect cash flows set forth in contract and/or sell the asset, and is measured at fair value through profit or loss. Financial instruments designated at fair value through profit or loss are used to eliminate or significantly reduce an accounting mismatch, and are therefore measured at fair value. 7.2 TAP Bond On March 14, 2016, the Company acquired Series A convertible bond issued by TAP ("TAP Bond") in the amount of €90 million. The TAP Bond has a maturity of 10 years from its issuance, with annual interest of 3.75% until September 20, 2016 and 7.5% in subsequent years. The accrued interest will be paid on the maturity date or early redemption of the securities, whichever occurs first. TAP Bond is being measured at fair value through profit or loss. 7.3 Breakdown of short-term investments Weighted average December 31, Description Maturity 2023 2022 TAP Bond 7.5 % Sep-26 780,312 733,043 780,312 733,043

ACCOUNTS RECEIVABLE	ACCOUNTS RECEIVABLE 8.1 Accounting policies Accounts receivable are measured based on the invoiced amount, net of expected losses on receivables, and approximate the fair value given their short-term nature. Considering the requirements of IFRS 9 – Financial Instruments, the allowance for expected losses on receivables is measured by applying the simplified approach, through the use of historical data, projecting the expected loss over the life of the contract, by segmenting the receivables portfolio into groups that have the same pattern of collection and according to their respective maturities. Additionally, for certain cases, the Company carries out individual analyses to assess the risks of collection of the receivables to recognize an additional provision, if necessary. 8.2 Breakdown of accounts receivable December 31, Description 2023 2022 Local currency Credit card companies 498,609 1,109,197 Cargo and travel agencies 282,654 282,438 Travel package financing entities 29,203 135,168 Loyalty program partners 114,932 69,035 Others 40,121 41,973 Total local currency 965,519 1,637,811 Foreign currency Credit card companies 18,556 15,913 Reimbursement receivable for maintenance reserves 57,528 78,801 Airline partner companies 8,612 39,612 Clearinghouse – agencies and cargo 30,533 26,363 Others 55,894 29,582 Total foreign currency 171,123 190,271 Total 1,136,642 1,828,082 Allowance for expected credit losses (27,234) (24,084) Total net 1,109,408 1,803,998 In Brazil, credit card receivables are not exposed to credit risk of the cardholder. The balances can easily be converted into cash, when necessary, by discounting these receivables with credit card companies.

Disclosure of aircraft sublease receivables [Abstract]
Aircraft sublease	AIRCRAFT SUBLEASE 9.1 Accounting policies Aircraft subleases are transactions whereby the lessee, in this case the Company, subleases an asset that is leased from a third party, thus becoming an intermediate lessor. IFRS 16 – Leases, requires an intermediate lessor to classify the sublease as finance or operating. Considering that the contracts entered into by the Company up to December 31, 2023 cover most of the term of the head lease, the subleases were accounted for as follows: • Derecognition of the right-of-use asset related to the head lease and recognition of the receivables arising from the sublease contracts at present value; • Recognition in profit or loss for the year of any difference between the right of use written off and the receivables arising from the sublease contract at present value; • The lease liability with respect to the head lease continued to be recognized in the statement of financial position; • Recognition of financial income over the term of the sublease; and • Recognition of financial expenses relating to obligations of the head lease contract. As of December 31, 2023, the Company has 3 aircraft under sublease (8 aircraft as of December 31, 2022). 9.2 Breakdown of aircraft sublease December 31, Description 2023 2022 2023 — 89,293 2024 15,386 70,396 2025 15,386 50,127 2026 4,001 7,951 Gross sublease 34,773 217,767 Accrued interest (3,971) (25,838) Provision for losses — (15,876) Net sublease 30,802 176,053 Current 14,592 70,193 Non-current 16,210 105,860

Disclosure of security deposits and maintenance reserves [Abstract]
Security deposits and maintenance reserves	DEPOSITS 11.1 Accounting policies 11.1.1 Security deposits Security deposits are represented by amounts deposited by the Company, mostly to the lessors of aircraft and engines, as guarantee for the fulfillment of the lease contract. Security deposits do not bear interest and are reimbursable at the end of the contracts. Judicial deposits are also classified in this group. 11.1.2 Maintenance reserves Certain master lease agreements provide for the payment of aircraft and engine maintenance reserves made to the lessors to be held as collateral for the performance of major maintenance activities, and therefore these deposits are reimbursable upon completion of the maintenance event in an amount equal to or less than: • the amount of the maintenance reserve held by the lessor associated with the specific maintenance event; or • the costs related to the specific maintenance event. Substantially all of these maintenance reserve payments are calculated based on an aircraft utilization measure, such as flight hours or cycles. As of the reporting date, we assess whether the maintenance reserve deposits required by the master lease agreements are expected to be recovered based on the expected future usage of the aircraft and timing of future maintenance events. A provision for loss is recognized for deposits that are not likely to be recovered. Aircraft and engine maintenance reserves are classified as current or non-current depending on the dates on which the amounts are expected to be recovered. 11.2 Breakdown of deposits December, 31 Description 2023 2022 Security deposits 418,537 374,960 Maintenance reserves 2,153,310 2,610,943 Total 2,571,847 2,985,903 Provision for loss (278,352) (446,342) Total, net 2,293,495 2,539,561 Current 515,692 1,025,168 Non-current 1,777,803 1,514,393 The movement of security deposits and maintenance reserves is as follows: Description Security deposits Maintenance reserves Total At December 31, 2021 319,530 1,644,889 1,964,419 Additions 123,796 714,079 837,875 Transfers (48,688) (14,847) (63,535) Provision inclusions and (reversals), net — (15,110) (15,110) Use by the lessor — (59,721) (59,721) Foreign currency exchange (19,678) (104,689) (124,367) At December 31, 2022 374,960 2,164,601 2,539,561 Additions 234,972 357,759 592,731 Transfers (169,432) (417,725) (587,157) Provision inclusions and (reversals), net — 135,284 135,284 Use by the lessor — (221,054) (221,054) Foreign currency exchange (21,963) (143,907) (165,870) At December 31, 2023 418,537 1,874,958 2,293,495 Current 64,788 450,904 515,692 Non-current 353,749 1,424,054 1,777,803 At December 31, 2022 Current 77,241 947,927 1,025,168 Non-current 297,719 1,216,674 1,514,393 The movement of the allowance for maintenance reserves losses is as follows:

Major components of tax expense (income) [abstract]
INCOME TAX AND CONTRIBUTION	INCOME TAX AND CONTRIBUTION 14.1 Accounting policies 14.1.1 Current taxes In Brazil, current taxes comprise corporate income tax (“IRPJ”) and social contribution on profit (“CSLL”), which are calculated monthly based on the taxable profit, after offsetting tax losses carryforwards, limited to 30% of taxable profit. A combined rate of 34% applies to this base. Income from foreign subsidiaries is subject to taxation in accordance with the rates and legislation in force. In Brazil such income is taxed in accordance with Law No. 12,973/14, which states that a parent company of a foreign subsidiary adds such income to its taxable income for the period. 14.1.2 Deferred taxes Deferred taxes represent credits and debits on tax loss carryforwards, as well as temporary differences between the tax and accounting bases. Deferred tax and contribution assets and liabilities are classified as non-current. An impairment loss on these assets is recognized when the Company's internal studies indicate that the future use of these credits is not likely. Deferred tax assets and liabilities are presented net if there is a legally enforceable right to set off tax liabilities against tax assets, and if they are related to taxes levied by the same tax authority on the same taxable entity, therefore, for presentation purposes, balances of tax assets and liabilities which do not meet the legal criteria for realization are disclosed separately. Deferred tax assets and liabilities are measured at the rates that are expected to be applicable in the period in which the asset is realized or the liability is settled, based on the tax rates and legislation in force at the reporting date. The projections of future taxable profits on tax loss carryforwards are prepared based on the business plans and are reviewed and approved annually by the Board of Directors. 14.1.3 Uncertainty over income tax treatments On January 1, 2019, the accounting standard IFRIC 23 – Uncertainty over Income Tax Treatments, became effective, addressing the application of recognition and measurement requirements when there is uncertainty over income tax treatments. The Company analyzes relevant tax decisions of higher courts and whether they conflict in any way with the positions adopted. For known uncertain tax positions, when necessary, the Company establishes a provision based on the legal opinions issued by its legal advisors. The Company evaluates continuously the positions taken in which there are uncertainties about the tax treatment adopted. 14.1.4 International Tax Reform – Pillar Two Model Rules Amendments to IAS 12 – Income Taxes, became effective in response to the Organization for Economic Co-operation and Development (“OECD”) Pillar Two rules on Base Erosion and Profit Shifting (“BEPS”): These changes had no impact on the Company's consolidated financial statements. 14.2 Breakdown of deferred taxes Description December 31, Profit or loss December 31, Deferred tax liability on taxable temporary differences Breakage (176,884) (19,039) (195,923) Foreign currency exchange — (191,219) (191,219) Leases (2,620,461) (414,124) (3,034,585) Others (516) (541) (1,057) (2,797,861) (624,923) (3,422,784) Deferred tax asset on deductible temporary differences 2,797,861 585,397 3,383,258 Total income tax and deferred social contribution — (39,526) (39,526) Provision for deferred taxes — (39,526) (39,526) 14.3 Reconciliation of the effective income tax rate December 31, Description 2023 2022 2021 Loss before income tax and social contribution (2,340,930) (722,367) (4,213,208) Combined nominal tax rate 34 % 34 % 34 % Taxes calculated at nominal rates 795,916 245,605 1,432,491 Adjustments to determine the effective rate Result from investments not taxed abroad 298,972 100,586 — Unrecorded benefit on tax losses and temporary differences (1,189,039) (700,826) (1,593,326) Mark to market of convertible debt instruments (8,584) 176,737 281,932 Permanent differences 43,764 154,669 (116,876) Rate differential 24,377 29,189 — Others (4,932) (5,960) (4,221) (39,526) — — Deferred income tax and social contribution (39,526) — — — — — Effective rate (1.7) % — % — % The Company has tax losses that are available indefinitely for offset against 30% of future taxable profits on which deferred tax assets were not recognized as it is not probable that future taxable profits will be available for offset, as below: December 31, Description 2023 2022 2021 Tax loss and negative bases 18,325,916 12,863,038 8,843,805 Tax loss (25%) 4,581,479 3,215,760 2,210,951 Negative social contribution base (9%) 1,649,332 1,157,673 795,942

Property, plant and equipment [abstract]
PROPERTY AND EQUIPMENT	PROPERTY AND EQUIPMENT 15.1 Accounting policies Property and equipment, are stated at acquisition cost. Depreciation is calculated according to the estimated economic useful life of each asset using the straight-line method. The estimated economic useful lives, residual values and depreciation methods are reviewed annually and the effects of any changes in estimates are accounted for prospectively. The carrying amounts of property and equipment items are tested annually to identify any indication of impairment or when facts or changes in circumstances indicate that the carrying amount is greater than the estimated recoverable amount. An item of property and equipment is derecognized upon its disposal or when no future economic benefits are expected from the continued use of the asset. Any gains or losses arising on the sale or derecognition of an item are determined by the difference between the amount received on the sale and the carrying amount of the asset and are recognized in profit or loss. The Company receives credits from manufacturers when purchasing certain aircraft and engines, which can be used to pay for maintenance services. These credits are recorded as a reduction in the acquisition cost of aircraft and related engines. During the year ended December 31, 2023, the Company hired experts to review the useful life of its property and equipment. This review had no impact on these financial statements. 15.1.1 Sale and leaseback transactions Initially, sale and leaseback transactions are analyzed within the scope of IFRS 15 – Revenue from Contracts with Customers, in order to verify whether the performance obligation has been satisfied, and therefore to account for the sale of the asset. If this requirement is not met, it is a finance arrangement with the asset given as guarantee. If the requirements related to the performance obligation set out are met, the Company measures a right-of-use asset arising from the sale and leaseback transaction in proportion to the carrying amount of the asset related to the right of use retained by the Company. Accordingly, only the gains or losses related to the rights transferred to the buyer-lessor are recognized. During the year ended December 31, 2023, the Company carried out a “sale and leaseback” transaction for an engine, where the proceeds, net of sales costs, amounted to a loss of R$6,356 (gain of R$33,155 as of December 31, 2022) and was recognized in the statement of operations under the line item “Other”. 15.1.2 Advance payments for acquisition of aircraft Advance payments for the acquisition of aircraft are recognized in property and equipment. 15.2 Breakdown of property and equipment Description Weighted average rate (p.a.)

Property, plant and equipment [abstract]
Right-of-use Asset	RIGHT-OF-USE ASSETS 16.1 Accounting policies IFRS 16 – Leases, requires lessees at the commencement date of a contract to recognize a lease liability to make payments and an asset representing the right to use the underlying asset over the lease term (a right-of-use asset - “ROU”). Lessees must separately recognize interest expense on the lease liability and the depreciation expense of the right-of-use asset in profit or loss. Lessees are also required to reassess the lease liability in the event of certain events, for example, a change in the lease term, or a change in future lease payment flows as a result of a change in an index or rate used to determine such payments. In general, the lessee must recognize the remeasurement amount of the lease liability as an adjustment to the right-of-use asset. Considering the dollar-denominated environment in which the Company raises funds, in determining the discount rate the Company used as a basis incremental borrowing rates at the commencement and/or modification dates of the lease agreements in foreign currency. 16.1.1 Componentization of aircraft At the receipt and initial recognition of right-of-use assets, the Company allocates the total cost of the aircraft between five major components, airframe, auxiliary power unit (“APU”) or propeller, landing gear and two engines. The useful life of each component is determined according to the estimated period until the next maintenance event, limited to the end of the lease term and/or the estimated useful life of the component. 16.1.2 Capitalization of heavy maintenance events Heavy maintenance events that increase the useful life of assets are capitalized. Such contracts can be of the “power-by-the-hour” type, in which the amounts owed to maintenance providers are calculated based on the flight hours and cycles. Subsequently, they are depreciated during the respective period of use considering the shorter period between the next scheduled maintenance event or until the end of the lease. Repairs and other routine maintenance are recognized in profit or loss in the period in which they are incurred. 16.1.3 Recognition of contractual obligations relating to return of aircraft The costs resulting from the maintenance events that will be carried out immediately before the return of the aircraft to the lessors are recognized as an obligation at present value, with an offsetting entry increasing the cost of the asset, as long as they can be reasonably estimated. Assets are depreciated on a straight-line basis over the lease contract term, while liabilities are updated by interest rates and exchange effects. 16.2 Breakdown of right-of-use assets Description Weighted average rate (p.a.)

Intangible assets and goodwill [abstract]
INTANGIBLE ASSETS	INTANGIBLE ASSETS 17.1 Accounting policies 17.1.1 Definite useful life Intangible assets acquired are measured at cost at the time of their initial recognition. After initial recognition, intangible assets with finite useful lives, generally software, are stated at cost, less accumulated amortization and accumulated impairment losses, where applicable. Intangible assets generated internally, excluding development costs, are not capitalized and the expense is recognized in profit or loss when incurred. 17.1.2 Indefinite useful life 17.1.2.1 Goodwill Goodwill was recognized from the business combinations of IntelAzul and Conecta. Goodwill is tested annually for impairment by comparing the carrying amount of the CGU to which goodwill has been allocated with its value in use. Management makes judgments and establishes assumptions to assess the impact of macroeconomic and operational changes, in order to estimate future cash flows and measure the recoverable amount of its CGU. 17.1.2.2 Rights of operations in airports (slots) In the business combinations of IntelAzul and Conecta, slots were acquired that were recognized at their fair values on the acquisition date and not amortized. The estimated useful life of these rights was considered indefinite due to several factors and considerations, including applications and authorizations for permission to operate in Brazil and limited availability of operating rights at the most important airports in terms of air traffic volume. Slots are tested annually for impairment by comparing the carrying amount of the CGU to which slots have been allocated with its value in use. 17.2 Breakdown of intangible assets Description Weighted average rate (p.a.)

The assumptions used in the impairment tests of goodwill and slots are consistent with the Company's operating plans and internal projections, prepared for a period of five years. After this period, a perpetuity rate of growth of operating projections is assumed. The discounted cash flow that determined the value in use of the cash-generating unit was prepared according to the Company’s business plan approved by the Board of Directors in December 2023. The following assumptions were considered: • Fleet and capacity : plan for operational fleet, utilization and capacity of aircraft in each route; • Passenger revenue : historical revenue per seat per kilometer flown with growth in line with the Company's business plan; • Operating costs : specific performance indicators by cost line, in line with the Company's business plan, as well as macroeconomic assumptions; and • Investment needs : aligned with the Company’s business plan. The macroeconomic assumptions commonly adopted include the Gross Domestic Product (“GDP”) and projections of the US dollar, both obtained from the Focus Report issued by the Central Bank of Brazil, in addition to future kerosene barrel prices and interest rates, obtained from specific Bloomberg disclosures. The result of the goodwill and slots impairment test demonstrated that the estimated recoverable amount of the CGU is significantly greater than its carrying amount and, therefore, no impairment loss was identified. To estimate the value in-use of the CGU, a pre-tax discount rate of 11.4% (11.5% as of December 31, 2022) and a growth rate in perpetuity of 3.0% (3.0% as of December 31, 2022) were used.

Convertible Instruments	CONVERTIBLE DEBT INSTRUMENTS 20.1 Accounting policies As required by IFRS 9 – Financial Instruments, the right to convert convertible debentures into shares was measured at fair value through profit or loss as it is an embedded derivative. 20.2 Renegotiations In July 2023, the Company concluded the renegotiation of the convertible debentures, with a principal value of R$1,745,900, changing the maturity date from October 2025 to October 2028, at a nominal rate of 6.0% p.a. to 12.3% p.a. and the conversion price from R$32.26 to R$22.78. In accordance with IFRS 9 – Financial Instruments, the Company concluded that the renegotiation of the debentures falls within the scope of debt extinguishment. Therefore, the values recorded previously were extinguished and a new debt was recorded. For this reason, any costs or fees incurred were recognized in the statement of operations. Due to the modification of the debt, the amount of R$352,430, composed of the effect of the restructuring of R$233,068 (expenses of R$346,555 related to the extinction and reconstitution of the conversion right and income of R$113,487 related to the extinction and reconstitution of the debt) and R$119,362 of new costs incurred, was recorded in the statement of operations, under the line “Restructuring of debentures”.

Provisions [abstract]
PROVISIONS	PROVISIONS 28.1 Accounting policies 28.1.1 Provision for return of aircraft and engines Aircraft and engines held under lease agreements without purchase options have contractual obligations establishing conditions for their return. The Company provides for return costs, since these are present obligations arising from past events and which will generate future disbursements, which are reliably measured. These expenses basically refer to aircraft reconfiguration (interior and exterior), obtaining licenses and technical certifications, verifications of returns, maintenance, painting, etc., as established in the contract. The estimated cost of return is initially recognized at present value as part of the cost of right-of-use assets, and the provision for aircraft return costs is recorded in the “Provisions” account. After initial recognition, the liability is updated according to the capital remuneration rate estimated by the Company, with a corresponding entry recorded in the financial result. Any changes in the estimate of expenses to be incurred are recognized prospectively against the right of use asset or in the statement of operations for the year, if the right-of-use balance is insufficient. 28.1.2 Tax, civil, labor and other risks The Company is party to several legal and administrative proceedings, mainly in Brazil. Assessments of the likelihood of loss in these cases include an analysis of the available evidence, the hierarchy of laws, the available case laws, the most recent court decisions and their significance in the legal system, as well as the assessment of external lawyers. Provisions are revised and adjusted to reflect changes in circumstances, such as the applicable statute of limitations, conclusions of tax inspections or additional exposures identified based on new matters or court decisions.

Earnings per share [abstract]
Earnings (Loss) Per Share	EARNINGS (LOSS) PER SHARE 31.1 Accounting policies Basic earnings (loss) per share is calculated by dividing the profit or loss for the year attributed to the Company's controlling shareholders by the weighted average number of all classes of shares outstanding, except treasury shares, during the year. Diluted earnings (loss) per share is calculated by adjusting the weighted average number of shares outstanding, except treasury shares, by instruments potentially convertible into shares. However, due to the losses reported in the years ended December 31, 2023, and 2022, these instruments issued by the company have a non-dilutive effect and therefore were not considered in the total number of shares outstanding to determine the diluted loss per share. Although there are differences between common and preferred shares as to voting and preemptive rights in the event of liquidation, the Company's preferred shares do not grant the right to receive fixed dividends. Preferred shares have economic power and the right to receive dividends 75 times greater than common shares. Accordingly, the Company considers that the economic power of preferred shares is greater than that of common shares. Therefore, the profit or loss for the year attributable to the controlling shareholders is allocated proportionally in relation to the total economic participation of the amount of common and preferred shares. 31.2 Earnings (loss) per share calculation Years ended December 31, Description 2023 2022 2021 Numerator Loss for the year (2,380,456) (722,367) (4,213,208) Denominator Weighted average number of common shares 928,965,058 928,965,058 928,965,058 Weighted average number of preferred shares 335,145,967 335,291,821 333,286,277 Economic value of preferred shares 75 75 75 Weighted average number of equivalent preferred shares (a) 347,532,168 347,678,022 345,672,478 Weighted average number of equivalent common shares (b) 26,064,912,583 26,075,851,633 25,925,435,858 Weighted average number of presumed conversions 220,081,929 77,059,124 63,296,103 Weighted average number of preferred shares that would have been issued the average share price at the market price 4,041,744 3,290,760 2,711,861 Average share price at market price (in reais) 14.35 18.17 36.87 Basic loss per common share – R$ (0.09) (0.03) (0.16) Diluted loss per common share – R$ (0.09) (0.03) (0.16) Basic loss per preferred share – R$ (6.85) (2.08) (12.19) Diluted loss per preferred share – R$ (6.85) (2.08) (12.19) (a) This refers to the participation in the value of the Company's total equity, calculated as if all 928,965,058 common shares had been converted into 12,386,201 preferred shares at the conversion ratio of 75 common shares for each preferred share.

SHARE-BASED PAYMENT	SHARE-BASED PAYMENT 32.1 Accounting policies The Company offers executives share-based compensation plans to be settled with Company shares or cash, according to which the Company receives services as consideration. The cost of instruments is measured based on fair value on the date they were granted or at the end of the reporting period for phantom shares. To determine the fair value of purchase options, the Company uses the Black-Scholes model. The cost of transactions settled with equity securities is recognized in profit or loss under “Salaries and benefits”, together with a corresponding increase in the “Capital reserve” or “Salaries and benefits” liability for phantom shares, over the period in which performance and/or service condition are met, ending on the date on which the employee acquires the full right to the award (vesting date) or settlement and cancellation for phantom shares. The outstanding liability is revalued at fair value at the end of the reporting period. 32.2 Compensation plans The Company has three share-based compensation plans: the Stock Option Plan (“Option Plan”), the Restricted Stock Option Plan (“RSU”) and the Stock Purchase Plan ("phantom shares"). All of them aim to stimulate and promote the alignment of the objectives of the Company, shareholders, management and employees, and mitigate the risks in the generation of value of the Company by the loss of its executives, strengthening their commitment and productivity in the long-term results. The movement of the plans is as follows: Number of shares Description Option plan RSU Phantom shares Total At December 31, 2021 3,923,686 1,366,386 5,136,682 10,426,754 Granted 17,089,417 1,006,779 — 18,096,196 Exercised (1,943,398) (479,098) — (2,422,496) Canceled — (98,666) (4,810,210) (4,908,876) At December 31, 2022 19,069,705 1,795,401 326,472 21,191,578 Granted 1,800,000 500,000 — 2,300,000 Exercised (124,388) (609,313) (22,884) (756,585) Canceled (223,633) (142,023) (56,658) (422,314) At December 31, 2023 20,521,684 1,544,065 246,930 22,312,679 December, 31 Description 2023 2022 Share price (in reais) 16.01 11.01 Weighted average price of the stock option (in reais) 12.93 11.84 Weighted average price of the phantom shares (in reais) 10.35 — Cash inflow stock option plan 1,608 23,006 Flat cash inflow of phantom shares 237 — Total obligation related to the phantom shares 1,736 844 Income tax regarding RSU transfer 3,239 1,427 The expenses of share-based compensation plans are shown below: Years ended December, 31 Description 2023 2022 2021 Option plan 61,646 29,368 5,933 RSU 9,093 1,366 15,877 Phantom shares 904 (48,984) (4,630) 71,643 (18,250) 17,180 The reversal of expenses in 2022 and 2021 was due to the reduction in the fair value of shares in these periods. 32.3 Assumptions 32.3.1 Option plan During the third quarter of 2023, the Company granted one program with the following conditions: Date of grant Option exercise price (in R$) Fair value of the option on the grant (in R$) Historical volatility Expected dividend Average risk-free rate of return Exercise rate per tranche Deadline remainder of vesting period (in years) Purchasing period up to (years) Total options granted Total outstanding options Total options available for exercise December 11, 2009 3.42 1.93 47.7 % 1.1 % 8.8 % 25.0 % 0.0 4.0 5,032,800 182,870 182,870 March 24, 2011 6.44 4.16 54.8 % 1.1 % 12.0 % 25.0 % 0.0 4.0 1,572,000 84,000 84,000 April 5, 2011 6.44 4.16 54.8 % 1.1 % 12.0 % 25.0 % 0.0 4.0 656,000 6,200 6,200 June 30, 2014 19.15 11.01 40.6 % 1.1 % 12.5 % 25.0 % 0.0 4.0 2,169,122 708,993 708,993 July 1, 2015 14.51 10.82 40.6 % 1.1 % 15.7 % 25.0 % 0.0 4.0 627,810 177,592 177,592 July 1, 2016 14.50 10.14 43.1 % 1.1 % 12.2 % 25.0 % 0.0 4.0 820,250 280,124 280,124 July 6, 2017 22.57 12.82 43.4 % 1.1 % 10.3 % 25.0 % 0.0 4.0 680,467 442,796 442,796 March 14, 2017 11.85 4.82 50.6 % 1.1 % 11.3 % 20.0 % 0.0 5.0 9,343,510 — — August 8, 2022 11.07 8.10 70.0 % — % 13.0 % 25.0 % 2.6 4.0 1,774,418 1,731,390 439,962 August 8, 2022 11.07 6.40 68.8 % — % 13.2 % 25.0 % 1.6 4.0 1,514,999 1,399,999 669,500 August 19, 2022 11.07 7.39 67.2 % — % 13.6 % 100.0 % 0.0 1.0 4,900,000 4,824,333 4,824,333 August 19, 2022 11.07 11.54 74.6 % — % 12.7 % 33.0 % 3.6 5.0 8,900,000 8,900,000 — July 7, 2023 15.60 10.80 75.4 % — % 11.6 % 25.0 % 3.5 4.0 1,800,000 1,783,387 — 39,791,376 20,521,684 7,816,370 32.3.2 RSU During the third quarter the 2023, the Company granted one program with the following conditions: Date of grant Exercise rate per tranche Fair value of share Remaining term of the vesting period (in years) Purchasing period up to (years) Total Total not July 7, 2019 25.0 % 51.65 0.0 4.0 170,000 — June 19, 2020 25.0 % 21.80 0.4 4.0 1,382,582 255,126 July 7, 2021 25.0 % 42.67 1.5 4.0 300,000 118,661 July 7, 2022 25.0 % 11.72 2.5 4.0 335,593 230,693 July 7, 2022 25.0 % 11.72 2.5 4.0 671,186 444,761 July 7, 2023 25.0 % 19.32 3.5 4.0 500,000 494,824 3,359,361 1,544,065 32.3.3 Phantom shares Date of grant Option exercise price Average fair value of option Historical volatility Expected dividend Average risk-free rate of return Exercise rate per tranche Remaining term of the vesting period Purchasing period up to (years) Total granted Total outstanding Total options available for exercise August 7, 2018 20.43 3.89 74.9 % 0 % 10.0 % 25.0 % 0.0 4.0 707,400 53,520 53,520 July 7, 2019 42.09 1.08 74.9 % 0 % 10.0 % 25.0 % 0.0 4.0 405,000 — — April 30, 2020 10.35 7.87 74.9 % 0 % 10.0 % 33.3 % 0.0 3.0 3,250,000 153,160 153,160 April 30, 2020 10.35 8.60 73.8 % 0 % 9.8 % 25.0 % 0.3 4.0 1,600,000 38,820 38,820 August 17, 2021 33.99 3.46 71.4 % 0 % 9.8 % 25.0 % 1.6 4.0 580,000 1,430 1,430 6,542,400 246,930 246,930

SALES REVENUE	REVENUE 33.1 Accounting policies 33.1.1 Revenue from passenger transport Revenue from passenger transport is recognized when air transportation is actually provided. Tickets sold, but not yet used are recorded as “Air traffic liability and loyalty program” account, net of breakage revenue estimate (note 25). Breakage revenue represents tickets issued that are expected to expire unused, that is, passengers who have purchased tickets and are very likely not to use them. Breakage revenue is estimated using statistical models primarily based on historical data, ticket terms and customers’ travel behavior. Breakage revenue is recognized in proportion to the usage of the related tickets. At least annually, the calculations and the statistical model are reviewed in order to reflect and capture changes in customer behavior regarding ticket expiration. Other revenues that include charter services, flight rescheduling fees, baggage dispatch and other additional services are recognized when the services are rendered. In the loyalty program, customers accumulate points based on the amount spent on air transportation and in accordance with the partners' rules. The amount of points earned depends on the customer's category in the loyalty program, market, fare class and other factors including promotional campaigns. Using historical data, the Company estimates the points that will expire without being used and recognizes the corresponding revenue in the issue of the point (breakage) considering the average exchange term. When the transportation service occurs, the portion of the ticket price allocated to air transportation is recognized as revenue and the portion corresponding to loyalty program points is deferred in accordance with IFRS 15. The Company determines the estimated selling price of the air transportation and points as if each element had been sold on a separate basis and was therefore based on the stand-alone selling price. The Company also sells loyalty program points to customers and partners, including credit card companies, financial institutions and retail companies. The related revenue is deferred and recognized when points are redeemed, based on the weighted average price of points sold. Issued points not yet used are recognized under “Air traffic liability and loyalty program”, until their effective use or expiration. 33.1.2 Other revenue Other revenues mainly include the transportation of cargo and travel packages and are recognized when performance obligations are met. 33.2 Breakdown of revenue Years ended December 31, Description 2023 2022 2021 Passenger revenue 17,229,732 15,020,757 9,101,576 Other revenues 1,487,286 1,513,582 1,301,090 Total 18,717,018 16,534,339 10,402,666 Taxes levied Passenger revenue (2,004) (425,812) (290,532) Other revenues (160,589) (160,460) (136,405) Total taxes (a) (162,593) (586,272) (426,937) Total revenue 18,554,425 15,948,067 9,975,729 (a) As of January 1, 2023, the PIS and COFINS rates on revenues arising from regular passenger air transport activities were reduced to zero, in accordance with Law 14,592/2023.

RISK MANAGEMENT	RISK MANAGEMENT 35.1 Accounting policies Operating activities expose the Company to the following financial risks: (i) market risk, related to interest rate, fuel price and exchange rate, (ii) credit risk and (iii) liquidity risk. The risks are monitored by the Company’s management and can be mitigated through the use of swaps, terms and options, interest, in the oil markets and currency . All activities with derivative financial instruments for risk management are carried out by specialists with skill, experience and adequate supervision. It is the Company's policy not to operate transactions for speculative purposes. 35.2 Fair value hierarchy of financial instruments The following hierarchy is used to determine the fair value of financial instruments: Level 1: quoted prices, without adjustment, in active markets for identical assets and liabilities; Level 2: other techniques for which all inputs that have a significant effect on the fair value recorded are directly or indirectly observable; and Level 3: techniques that use data that have a significant effect on the fair value recorded that are not based on observable market data. The fair value hierarchy of the Company's consolidated financial instruments, as well as the comparison between carrying amounts and fair values, are presented below: Carrying amount Fair value December 31, December 31, Description Note Level 2023 2022 2023 2022 Assets Cash and cash equivalents 6 2 1,897,336 668,348 1,897,336 668,348 Long-term investments 7 2 780,312 733,043 780,312 733,043 Derivative financial instruments 23 2 21,909 271,950 21,909 271,950 Liabilities Loans and financing 18 2 (9,698,912) (7,232,699) (9,796,608) (6,187,389) Convertible instruments 20 2 (712,835) (1,286,748) (712,835) (1,286,748) Convertible debt instruments – conversion right 20 2 (488,775) (116,971) (488,775) (116,971) Derivative financial instruments 23 2 (69,745) (244,575) (69,745) (244,575) Financial instruments carried at amortized cost whose fair value is a reasonable approximation of their book value, mainly due to the short maturity of these assets and liabilities, have not been presented above. 35.3 Market risks 35.3.1 Interest rate risk 35.3.1.1 Sensitivity analysis As of December 31, 2023, the Company held financial assets and liabilities linked to various types of rates. In the sensitivity analysis of non-derivative financial instruments, the impact on annual interest was only considered on positions with values exposed to such fluctuations: Consolidated Exposure to CDI Exposure to SOFR Exposure to LIBOR Description Rate (p.a.)

The Company estimates that the updated cash flows will be economically equivalent to the original ones. 35.3.1 Aircraft fuel price risk (“QAV”) The price of fuel may vary depending on the volatility of the price of crude oil and its derivatives. To mitigate losses linked to variations in the fuel market, the Company had, as of December 31, 2023, forward transactions on fuel (note 23). 35.3.2.1 Sensitivity analysis The following table demonstrates the sensitivity analysis in US dollars of the price fluctuation of QAV liter: Exposure to price Description Average price per liter December 31, 2023 Aircraft fuel 4.85 (5,890,485) Effect on profit or loss Devaluation by -50% 2.43 2,945,243 Devaluation by -25% 3.64 1,472,621 Appreciation by 50% 7.28 (2,945,243) Appreciation by 25% 6.06 (1,472,621) 35.3.1 Foreign exchange risk The foreign exchange risk arises from the possibility of unfavorable exchange differences to which the Company's cash flows are exposed. The equity exposure to the main variations in exchange rates is shown below: Exposure to US$ Exposure to € December 31, December 31, Description 2023 2022 2023 2022 Assets Cash and cash equivalents 82,975 56,487 4,092 8,052 Long-term investments — — 780,312 733,043 Accounts receivable 115,024 166,012 2,876 — Aircraft sublease 30,802 176,053 — — Deposits 2,196,474 2,471,349 — — Other assets 26,207 12,636 — — Total assets 2,451,482 2,882,537 787,280 741,095 Liabilities Loans and financing (8,889,048) (5,879,553) — — Leases (14,043,101) (14,525,385) — — Convertible debt instruments (1,201,610) (1,419,738) — — Accounts payable (2,040,546) (1,031,059) — — Airport taxes and fees (21,994) (20,320) — — Provisions and other liabilities (2,681,857) (3,020,947) — — Total liabilities (28,878,156) (25,897,002) — — Net exposure (26,426,674) (23,014,465) 787,280 741,095 Net exposure in foreign currency (5,458,590) (4,410,845) 147,111 133,066 35.3.3.1 Sensitivity analysis Exposure to US$ Exposure to € Description Closing rate December 31, Closing rate December 31, Exposed assets (liabilities), net 4.8413 (26,426,674) 5.3516 787,280 Effect on profit or loss Foreign currency devaluation by -50% 2.4207 13,213,337 2.6758 (393,640) Foreign currency devaluation by -25% 3.6310 6,606,669 4.0137 (196,820) Foreign currency appreciation by 50% 7.2620 (13,213,337) 8.0274 393,640 Foreign currency appreciation by 25% 6.0516 (6,606,669) 6.6895 196,820 35.4 Credit risk Credit risk is inherent to the Company's operating and financial activities, mainly disclosed in cash and cash equivalents, long-term investments, accounts receivable, aircraft sublease, security deposits and maintenance reserves. Financial assets classified as cash and cash equivalents are deposited with counterparties that have a minimum investment grade rating in the assessment made by agencies S&P Global Ratings, Moody's or Fitch (between AAA and A+). The TAP Bond is guaranteed by intellectual property rights and credits related to the TAP mileage program. Credit limits are established for all customers based on internal classification criteria and the carrying amounts represent the maximum credit risk exposure. Outstanding receivables from customers are frequently monitored by the Company and, when necessary, allowances for expected credit losses are recognized. Derivative financial instruments are contracted on the over-the-counter market (OTC) from counterparties with a minimum investment grade rating, or on commodities and futures exchanges (B3 and NYMEX), which substantially mitigates the credit risk. The Company assesses the risks of counterparties in financial instruments and diversifies its exposure periodically. 35.5 Liquidity risk The maturity schedules of the Company’s consolidated financial liabilities as of December 31, 2023 are as follows: December 31, 2023 Description Carrying amount Contractual cash flows Until 1 year From 2 to 5 years After 5 years Loans and financing 9,698,912 15,035,043 2,068,226 10,066,315 2,900,502 Reverse factoring 290,847 294,164 294,164 — — Leases 15,146,411 25,123,150 3,936,476 13,921,792 7,264,882 Convertible debt instruments 1,201,610 1,883,787 143,109 1,740,678 — Accounts payable 3,598,768 3,988,050 2,370,980 1,138,958 478,112 Airport taxes and fees 1,760,083 2,019,044 759,679 1,259,365 — Derivative financial instruments 69,745 69,745 68,905 840 — 31,766,376 48,412,983 9,641,539 28,127,948 10,643,496 35.6 Capital management The Company seeks capital alternatives in order to satisfy its operational needs, aiming at a capital structure that it considers adequate for the financial costs and the maturity dates of funding and its guarantees.

Disclosure of changes in accounting estimates [abstract]
Consolidation	Consolidation The consolidated financial statements include information about the Company and its subsidiaries in which held direct or indirect control. Control of a subsidiary is achieved when Company is exposed, or has rights, to variable returns in such subsidiaries and has the power to influence the investee's operating and financial decisions. The financial statements of the subsidiaries have been prepared using the same accounting policies as the Company. All assets, liabilities, equity, income and expenses related to transactions between related parties are eliminated in full in the consolidation process.
Impairment	Impairment The Company performs an annual review for impairment indicators in order to assess events or changes in economic, technological, or operating conditions that may indicate that an asset is impaired. The recoverable amount of an asset or cash-generating unit is the higher of its fair value, less costs to sell and its value in use. When the carrying amount of an asset or cash-generating unit exceeds its recoverable amount, a provision for impairment is set up by adjusting the carrying amount. The previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine the asset's recoverable amount. The reversal is limited, so that the carrying amount of the asset does not exceed its recoverable amount, nor does it exceed the carrying amount previously determined, net of depreciation or amortization. In estimating the asset's value in use, estimated future cash flows are discounted to present value, using a pre-tax discount rate that reflects the weighted average cost of capital for the cash-generating unit.
Disclosure of Accounting Policy for Main accounting estimate Explanatory [Text Block]	Main accounting estimates As disclosed in explanatory note 3, Management makes judgments that have a significant effect on the amounts recognized in the consolidated financial statements, namely: Description Note Provision for impairment of aircraft and engines and onerous contracts 2.3 Provision for losses with maintenance reserves 11 Analysis of the recoverable value of goodwill and slots 17 Revenue from ticket breakage and loyalty programs 25 Provision for return of aircraft and engines 28.1.1 Provision for tax, civil, labor and other risks 28.1.2 The Company continually reviews the assumptions used in its accounting estimates.
