It should be noted that in Brazil the vaccination process had a high adherence by the population, which caused a drastic drop in the number of infected people and deaths, thus favoring the conditions for the resumption of passenger air transport. The Company's Management closely monitors developments related to the COVID-19 pandemic, assessing the impact on its business and especially on its crew and customers. Presented below is the evolution of the supply (ASK) and demand (RPK) in the COVID-19 pandemic period compared to 2019 levels (unaudited): During the COVID-19 pandemic, the Company’s management adopted strict measures to preserve cash, especially the postponement of lease and supplier payments, freezing of contracts, suspension of projects that contained non-essential expenditures, and continuous search for opportunities to reduce costs and to raise funds in the capital market, seeking the economic and financial equilibrium among all stakeholders. Throughout the year, management measures became more flexible, mainly due to the resumption of payments of lease and supplier considerations. The Company continues to manage diligently its financial resources in order to fulfill the obligations assumed. The Company continues to prioritize the well-being and health of its crew and customers and help Brazil to face the pandemic by offering free transportation of vaccines and medical equipment such as respirators and intubation cubes to the cities in our network. During the year ended December 31, 2021, there were no impacts on these consolidated financial statements related to changes in accounting estimates and/or provisions, the impacts are related to the postponement of fleet transformation plans and realization of the business growth potential. During the year ended December 31, 2020, as informed at the Extraordinary General Meeting, due to the crisis caused by the COVID-19 pandemic, the Portugal Government's negotiated an aid of €1.2 billion for the airline TAP with the European Commission, conditional upon, among other factors, eliminating the right to convert senior bonds, since they would not be diluted by the Portugal Government's financial contribution. As a consequence, the elimination of the conversion right resulted in a loss recognized in the consolidated statement of operations of R$637,639, recorded under “Result from related party transactions, net”. 1.3 Capital structure and net working capital The Company's Management, together with the Board of Directors, constantly monitors the Company's liquidity position and cash projections, as well as any factors that may affect the ability to generate revenue and the Company's ability to honor the financial commitments assumed. The position of equity and consolidated net working capital and their variations are presented below: December 31, December 31, Description 2021 2020 Variation 2019 Variation Net working capital (5,863,917) (4,795,208) (1,068,709) (2,723,289) (2,071,919) Equity (18,333,003) (14,148,750) (4,184,253) (3,519,174) (10,629,576) The variation in the balance of net working capital is mainly related to the increase in the positions of lease obligations and short-term loans and financing, both impacted by the devaluation of the real against the US dollar by approximately 7.4% in the year. Additionally, the lease liabilities position also includes postponed installments of obligations negotiated with lessors in the peak of the COVID-19 pandemic, which are expected to be settled gradually in the period between 2023 and 2027. The chart below shows the resumption of lease consideration payments (unaudited): In June 2021, the Company concluded its fundraising with the issuance of Senior Notes in the net amount of R$2,976,795 ( note 18.2 The Company has the ability to access the capital market at competitive costs, its latest relevant fundraising processes occurred within the period of the COVID-19 pandemic were subject to annual interest between 6.0% and 7.5%. The variation in the balance of negative equity position is mainly due to the developments of the second wave of the COVID-19 pandemic, which affected the demand for airline tickets in the period between March and June, and the effect of the 7.4% devaluation of the real against the US dollar during the year. A significant part of the operating costs is directly impacted by changes in exchange rates, such as fuel and maintenance, as well as the financial result, given that virtually all lease obligations and loans and financing are denominated in US dollars. During the year of 2021 the Company suffered unrealized exchange losses in the amount of R$1,443,046 (R$4,302,540 at December 31, 2020). Management continuously monitors the Company’s liquidity situation and will continue to adopt measures to strengthen its cash position, provide efficiency in costs and restrain operating expenses. These actions have proven to be efficient for the business continuity and sustainability. The Company ended the year with a position of cash, cash equivalents, accounts receivable and short-term aircraft sublease receivables totaling R$4,149,321 (R$4,155,471 at December 31, 2020). Management evaluated and concluded that the Company is in a position to continue its operations and comply with its obligations, according to the contracted maturities. This assessment is based on the Company's business plan approved by the Board of Directors on December 9, 2021. This assessment includes planned future actions, macroeconomic and aviation sector assumptions, such as: recovery in air transport demand, estimates of exchange rates and fuel prices. The Company's Management monitors and informs the Board of Directors about the performance achieved in relation to the approved plan and updates it as needed. Based on this conclusion, these consolidated financial statements have been prepared based on the principle of going concern. 1.4 Acceleration of fleet transformation In 2019, the Company’s management approved the Embraer E195 phase-out plan (“E1”). On the same date, the Company signed letters of intent for the sublease of these assets to other air operators. The change in the intended use of the aircraft triggered an impairment review that resulted in the recognition of impairment of these assets of R$2,075,582 and the constitution of an onerous liability of R$821,751 at that time. In the second quarter of 2021, there was a partial reversal of the impairment in the amount of R$103,017 due to Management’s decision to use 2 aircraft for cargo, thus changing the intended use of these assets. The COVID-19 pandemic triggered the postponement of the plans for delivery of aircraft to sub-lessors. One of letter of intent for sublease signed remains valid, three aircraft was delivered and 10 more units are scheduled to be delivered in the next year. On the other hand, as provided for in the signed letters, as a result of the adverse conditions that arose from the COVID-19 pandemic and predicting opportunities to use these aircraft in the Company's operations, one of letter intention corresponding to a total of 21 aircraft was canceled. As a result of such cancellation, the Company through asset recoverability studies, made a partial reversal of the provision initially recognized, in the amount corresponding to R$1,362,386. On December 31, 2021, the provision for impairment of assets corresponds to a total of 28 aircraft (51 aircraft and 4 engines at December 31, 2020). The main assumptions used in the analysis included: • Sublease revenue; • Estimated period for start of the sublease contracts; • Delivery and maintenance costs of aircraft; • Residual value for own aircraft at the end of sublease contracts; • Exchange rate; and • Pre-tax discount rate. Considering the updating of the macroeconomic assumptions and the Company’s business plans, the breakdown of the account balances and the movement of the provision are shown below: 1.4.1 Breakdown of balances of provision for impairment and onerous liability December 31, Description 2021 2020 Provision for impairment of ROU (605,651) (706,614) Provision for impairment of aircraft and engine (68,693) (211,062) Provision for impairment of rotables (225,797) (225,797) Provision for impairment of other assets (12,013) (75,075) Total provision for impairment of Company assets (912,154) (1,218,548) Provision for onerous liabilities (693,407) (1,340,522) Total (1,605,561) (2,559,070) 1.4.2 Movement of the provision for impairment and onerous liability Description Impairment of assets Onerous liabilities Total Balance at December 31, 2019 (2,075,582) (821,751) (2,897,333) Foreign currency exchange — (213,280) (213,280) Interest expense — (206,011) (206,011) Additions — (362,426) (362,426) Consumption 272,006 262,946 534,952 Maintenance reserves (20,486) — (20,486) Sale of aircraft 13,123 — 13,123 Renegotiation of lease contracts (lease modification) 581,926 — 581,926 Other 10,465 — 10,465 Balance at December 31, 2020 (1,218,548) (1,340,522) (2,559,070) Foreign currency exchange — (103,858) (103,858) Interest expense — (156,516) (156,516) Reversals 494,592 970,811 1,465,403 Additions (188,198) (201,523) (389,721) Consumption — 188,842 188,842 Initial recognition of sublease (*) — (50,641) (50,641) Balance at December 31, 2021 (912,154) (693,407) (1,605,561) (*) The balance was transferred from “Provision for onerous liabilities” to “Aircraft sublease receivables”, as it refers to the estimated amount of the sublease receivable for two aircraft delivered to Breeze. 1.5 Seasonality The Company’s operating revenues depend substantially on the general volume of passenger and cargo traffic, which is subject to seasonal changes. 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, which may affect the usual business seasonality.

BUSINESS COMBINATION	BUSINESS COMBINATION 2.1 Accounting policies The Company accounts for business combinations using the acquisition method. The cost of an acquisition is measured as the sum of the consideration transferred, which is measured at acquisition date fair value. Acquisition-related costs are expensed as incurred. In the acquisition of a business, Management assesses the assets acquired and liabilities assumed in order to classify and allocate them according to the contractual terms, economic circumstances and relevant conditions at the acquisition date. Goodwill is initially measured as the excess of the consideration transferred over the fair value of the net assets acquired (identifiable assets and liabilities assumed, net). After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For the purpose of impairment testing, goodwill is allocated to each of the cash-generating units that are expected to benefit from the acquisition. 2.2 Acquisition of Azul Conecta On May 14, 2020, the Company completed the acquisition of all the shares of Azul Conecta, previously called Two Táxi Aéreo Ltda. The transaction was approved without restrictions by the Brazilian Antitrust Authority (“CADE”) on March 27, 2020. On April 30, 2020, through a power of attorney, the Company assumed control of Azul Conecta, therefore, the transfer of control occurred before the closing date mentioned above, in accordance with IFRS-3 – Business Combinations. At this time, Azul Conecta offered regular passenger and cargo services to 39 destinations in Brazil, of which only seven were served by Azul. The acquired company also had 14 daily departure and arrival times on the auxiliary runway at Congonhas airport, the country’s main domestic terminal. Its fleet consisted of 17 own aircraft, model Cessna Caravan, a single-engine regional turboprop with a capacity for nine passengers. The total nominal amount of the transaction was R$123,000. Payment is being made in up to 30 monthly installments, ranging from R$3,000 to R$10,000, subject to certain contractual and market conditions, and a final payment of up to R$30 million, which will be kept deposited in a bank account as a guarantee in favor of the Company for a specified period. The Company completed the purchase price allocation report and such acquisition generated goodwill of R$147,915 allocated in line item “Goodwill”. The goodwill recognized is not deductible for income tax purposes. The identifiable assets acquired and assumed liabilities that were recognized at the acquisition date and the related fair value are shown below: Description Fair value of assets and liabilities Assets Cash and cash equivalents 3,971 Accounts receivable 3,637 Inventories 1,624 Taxes recoverable 1,399 Other assets 458 Property and equipment (a) 74,205 Intangible assets (b) 44,351 129,645 Liabilities Loans and financing (16,540) Accounts payable (5,764) Salaries, accruals and payroll charges (2,707) Taxes payable (824) Provision for tax, civil and labor risks (c) (136,507) Other liabilities (650) (162,992) Net assets acquired (33,347) Consideration at present value 114,568 Goodwill 147,915 Cash flows Net cash acquired with subsidiary 3,971 Payment (62,684) Net cash flow from acquisition (58,713) (a) The Company carried out the fair value measurement of property and equipment based on conditions at the acquisition date.

DECLARATION OF MANAGEMENT, BASIS FOR PREPARATION AND PRESENTATION OF THE FINANCIAL STATEMENTS	DECLARATION OF MANAGEMENT, BASIS FOR PREPARATION AND PRESENTATION OF THE FINANCIAL STATEMENTS The Company’s financial statements have been prepared in accordance with accounting practices adopted in Brazil and the 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 a functional and presentation currency and are expressed in thousands of reais, unless otherwise indicated. 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 revenues, expenses, assets and liabilities. However, the uncertainty related to these judgments, assumptions and estimates can lead to results that require a significant adjustment to the carrying amount of certain assets and liabilities in future years. The Company reviews its judgments, estimates, and assumptions on an ongoing basis. When preparing these consolidated financial statements, management used the following disclosure criteria: (i) regulatory requirements; (ii) relevance and specificity of the information on the Company's operations to users; (iii) informational needs of users of the consolidated financial statements; and (iv) information from other entities participating in the passenger air transport market. Management confirms that all relevant information specific to the consolidated financial statements, and only such information, is being evidenced and corresponds to that used by Management when carrying out its business management activities. In order to ensure a better presentation and comparability of balances, some reclassifications were carried out in the balance sheet and statements of operations of the previous year. The consolidated financial statements have been prepared based on the historical cost, except for the following material items recognized in the statements of financial position at fair value. • Short-term investments classified as cash and cash equivalents; • Short-term investments mainly comprised of TAP Bond; • Derivative financial instruments; and • Debenture conversion right 3.1 Approval and authorization for issue of the consolidated financial statements This document was prepared based on the local financial statements that were approved and its disclosure authorized by the Board of Directors on February 22, 2022.

Disclosure of significant accounting policies [abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES The significant 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 Azul held direct or indirect control. Control of a subsidiary is achieved when Azul 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 information of the subsidiaries has been prepared using the same accounting policies as the Company. All related party assets and liabilities, equity, income, expenses and cash flows related to transactions between related parties are eliminated in full in the consolidation process. 4.2 New accounting standards and interpretations adopted for the year On March 31, 2021, the IASB extended until June 30, 2022 the application of the practical expedient of IFRS-16 (“lease concessions”) as a result of the COVID-19 pandemic. In certain renegotiations of its lease contracts, the Company adopted the provisions of said standard and the effects on these consolidated financial statements are immaterial. 4.3 New accounting standards and pronouncements not yet adopted There are no other standards and interpretations issued and not yet adopted that, in Management’s opinion, may have a significant impact on the result or equity disclosed by the Company. 4.4 Segment information An operating segment is a component of the Company that develops business activities to obtain revenues and incur expenses. The operating segments reflect the way in which the Company's Management reviews the financial information for decision-making. The Company’s Management identified the operating segments that meet the quantitative and qualitative parameters of disclosure, namely: % Gross revenue Year ended December 31, Parameters 2021 2020 2019 Qualitative Passenger service n/a n/a n/a Quantitative Passenger service 87.5 % 86.7 % 94.9 % Cargo service 12.1 % 12.7 % 4.7 % Other revenue 0.4 % 0.6 % 0.4 % The Company regularly manages its business and makes resource allocation decisions considering the existence of only one operating segment, which is why the information for the cargo transportation is not being disclosed. 4.5 Significant accounting estimates As disclosed in note 3, Management makes judgments that have a significant effect on the amounts recognized in the financial statements, namely: • provision for impairment of aircraft, engines and onerous liability ( note 1.4 • business combination ( note 2 • allowance for expected losses ( note 7 • provision for inventory losses ( note 9 • analysis of recoverability of maintenance deposits ( note 10 • annual impairment test of deferred taxes ( note 14 • useful life of property and equipment and intangible assets with finite useful life (notes 15 and 17); • annual impairment test of goodwill ( note 17 • slot recovery analysis ( note 17 • ticket breakage revenue and frequent-flyer programs ( note 22 • provision for return of aircraft and engines ( note 23.1.1 • provision for tax, civil and labor risks ( note 23.1.3 • provision for post-employment benefits ( note 23.1.4 • share-based payment ( note 27 The Company continuously revises 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. 4.6 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 calculated based on the exchange rate in effect at the reporting date, and any difference resulting from currency conversion is recorded under the line item “Foreign currency exchange, net” in the statements of operations for the year. The exchange rates in Brazilian reais at the date of these consolidated financial statements are as follows: Final rate Average rate Year ended December 31, Year ended December 31, Description 2021 2020 2019 2021 2020 2019 U.S. dollar 5.5805 5.1967 4.0307 5.3956 5.1578 3.9461 Euro 6.3210 6.3779 4.5305 6.3784 5.8989 4.4159

SHORT AND LONG-TERM INVESTMENTS	SHORT-TERM INVESTMENTS 6.1 Accounting policies In the presentation and measurement of the financial investments, the Company considers the provisions of IFRS 9 – Financial Instruments, which determines that financial assets shall be initially measured at fair value less costs directly attributable to their acquisition. In turn, the subsequent measurement is divided into two categories: 6.1.1 Amortized cost Short-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 interest and principal (“SPPI”); and • The Company did not opt for the fair value methodology in order to eliminate measurement inconsistencies named “accounting mismatch”. 6.1.2 Fair value • Through comprehensive income : short-term investments shall be 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, i.e. the Company does not plan to hold the financial asset to collect cash flows set forth in contract and/or sell the asset, this shall be 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. 6.2 Breakdown of short-term investments 6.2.1 Short-term investments measured at fair value through profit or loss Effective interest rate p.a.

ACCOUNTS RECEIVABLE	ACCOUNTS RECEIVABLE 7.1 Accounting policies These 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 now 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 the respective maturities. Additionally, for certain cases, the Company carries out individual analyses to assess the risks of collection of the receivables and establish provision, if necessary. 7.2 Breakdown of accounts receivable December 31, Description 2021 2020 Local currency Credit card companies 411,092 394,895 Cargo and travel agencies 209,621 146,854 Travel package financing entities 106,824 56,870 TudoAzul Program partners 128,018 65,522 Other 32,896 52,713 Total local currency 888,451 716,854 Foreign currency Credit card companies 19,211 8,927 Reimbursement receivable for maintenance reserves 18,197 112,170 Airline partner companies 36,693 24,910 Insurance companies 4,194 7,150 Clearinghouse - agencies and cargo 26,085 10,340 Other 22,879 11,162 Total foreign currency 127,259 174,659 Total 1,015,710 891,513 Allowance for expected credit losses (17,817) (16,131) Total net 997,893 875,382 In Brazil, card receivables mainly come from flights that have already taken place and are not exposed to credit risk of the cardholder. Therefore, these receivables can easily be converted to cash when needed, through the discounting of these receivables with the card operators. As of December 31, 2021, reclassifications of R$105,277 were made to the line item “Other non-current assets” related to reimbursement receivable from the maintenance reserve of a lessor that entered court-supervised reorganization. The Company has past-due lease liabilities with such lessor in the amount of R$205,978, therefore, there is no risk of realization of such receivable. No provision for loss was established as of December 31, 2021. The breakdown of accounts receivable by maturity, net of allowance for expected losses, is as follows: December 31, Description 2021 2020 Not past due Up to 30 days 562,539 476,378 31 to 60 days 101,699 69,729 61 to 90 days 56,001 46,007 91 to 180 days 110,207 86,215 181 to 360 days 90,351 65,386 Not past due 920,797 743,715 Past due Up to 30 days 25,872 104,377 31 to 60 days 20,178 8,371 61 to 90 days 13,235 4,228 91 to 180 days 3,589 5,077 181 to 360 days 5,388 6,178 Over 360 days 8,834 3,436 Past due 77,096 131,667 Total 997,893 875,382 The movement of the allowance for expected losses is as follows: December 31, Description 2021 2020 Balances at the beginning of the year (16,131) (14,716) Business combination – Azul Conecta — (380) (Additions) reversals (5,921) (3,205) Write-off of uncollectible amounts 4,235 2,170 Balances at the end of the year (17,817) (16,131)

Aircraft sublease receivables	AIRCRAFT SUBLEASE RECEIVABLES 8.1 Accounting policies The sublease receivable is a transaction whereby the lessee, in this case the Company, subleases the asset that is the subject of a lease to 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, 2021 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 rights arising from the sublease contracts at present value; • Recognition of any difference between the right of use written off and the rights arising from the sublease contract at present value in statements of operations for the year; • Maintenance of the lease obligations of the host contract 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 host lease contract. 8.2 Breakdown of aircraft sublease receivables December 31, Description 2021 2020 2021 — 142,932 2022 92,092 62,547 2023 87,658 65,040 2024 87,817 65,188 2025 54,890 34,789 After 2025 4,615 1,994 Gross lease receivables 327,072 372,490 Accrued interest (52,874) (59,553) Net lease receivables 274,198 312,937 Current 76,199 123,455 Non-current 197,999 189,482 As of December 31, 2021, the amount of R$16,980 was past due (R$34,457 as of December 31, 2020). No provision was established as the Company has higher obligations arising from the receipt of security deposits advanced by the sub-lessor, and therefore there is no expectation of non-realization of such assets.

INVENTORIES	INVENTORIES 9.1 Accounting policies Inventory balances mainly comprise materials for maintenance and replacement of flight equipment parts. Inventories are measured at average acquisition cost plus expenses such as non-recoverable taxes, customs expenses incurred in the acquisition, and expenses with transportation to the warehouse. Expenses with freight transfers between operational bases are not capitalized, if incurred. Provisions for obsolescence of inventories are recorded for items not expected to be realized. 9.2 Breakdown of inventories December 31, Description 2021 2020 Maintenance parts and materials 597,204 442,161 Flight attendance and uniforms 13,655 9,579 Provision for obsolescence of inventories (38,935) (49,153) Total net 571,924 402,587 Set out below is the movement of the provision for obsolescence of inventories: December 31, Description 2021 2020 Balances at the beginning of the year (49,153) (33,727) Additions (10,681) (16,438) Write-offs 2,566 1,012 Reversal of impairment 18,333 — Balances at the end of year (38,935) (49,153)

Disclosure of security deposits and maintenance reserves [Abstract]
Security deposits and maintenance reserves	SECURITY DEPOSITS AND MAINTENANCE RESERVES 10.1 Accounting policies 10.1.1 Security deposits Security deposits are represented by amounts deposited by the Company to the lessors of aircraft, as required at the inception of the lease, as guarantee for the fulfillment of the lease contract. Security deposits are denominated in U.S. dollars, do not bear interest and are not reimbursable at the end of the contracts. Judicial deposits are also classified in this group. 10.1.2 Maintenance reserves Certain master lease agreements provide for the payment of aircraft 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, and are used solely to collateralize the performance of maintenance by the lessor. At the reporting date we assess whether the maintenance reserve deposits required by the master lease agreements are expected to be recovered through the performance of qualifying maintenance on the leased assets. Maintenance deposits expected to be recovered are held in assets, and the amounts identified as non-recoverable are readily transferred to statements of operations. Aircraft maintenance reserves are classified as current or non-current depending on the dates when the related maintenance is expected to be performed. 10.2 Breakdown of security deposits and maintenance reserves The movement of security deposits and maintenance reserves is as follows: Description Maintenance reserves Security deposits Total Balances at December 31, 2019 1,498,898 152,635 1,651,533 Business combination – Azul Conecta — 298 298 Additions 313,950 93,739 407,689 Impairment (20,486) — (20,486) Provision for loss (419,843) — (419,843) Reimbursements (476,588) (43,519) (520,107) Foreign currency exchange 425,715 29,243 454,958 Balances at December 31, 2020 1,321,646 232,396 1,554,042 Additions 501,309 95,799 597,108 Reversal of impairment 24,275 — 24,275 Provision for loss (221,626) — (221,626) Reimbursements (86,804) (48,584) (135,388) Transfer — 23,782 23,782 Foreign currency exchange 106,089 16,137 122,226 Balances at December 31, 2021 1,644,889 319,530 1,964,419 Current 357,210 53,702 410,912 Non-current 1,287,679 265,828 1,553,507

Major components of tax expense (income) [abstract]
TAXES	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 loss carryforwards, limited to 30% of the taxable profit. A 15% rate is applied to that base, plus 10% for IRPJ and 9% for CSLL. The 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. 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 present 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 shall be 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 quarterly evaluates the positions assumed in which there are uncertainties about the tax treatment adopted. 14.2 Reconciliation of deferred tax assets (liabilities) Description December 31, Profit or loss December 31, Temporary differences Fair value of TAP Bond (26,132) (5,417) (31,549) Financial instruments (121,960) 26,752 (95,208) Deferred revenue TudoAzul Program (117,540) (21,084) (138,624) Depreciation of aircraft and engines (53,182) 53,182 — Temporary differences assets (*) 318,814 (52,917) 265,897 Others — (516) (516) — — — (*) Deferred tax set up in the limit of the deferred obligations recognized. 14.3 Reconciliation of the effective income tax rate December 31, Description 2021 2020 2019 Loss before income tax and social contribution (4,213,208) (11,077,214) (2,536,265) Combined nominal tax rate 34 % 34 % 34 % Taxes calculated at nominal rates 1,432,491 3,766,253 862,330 Adjustments to determine the effective rate (Unrecorded) benefit on tax losses and temporary differences (1,311,394) (3,257,190) (880,375) Permanent differences (116,876) (244,011) 76,958 Taxation on universal bases (4,221) — (10,341) Offset against PERT — — 84,711 Others — (22,547) (104) — 242,505 133,179 Current income tax and social contribution — (11) (2,228) Deferred income tax and social contribution — 242,516 135,407 Income tax and social contribution credit (expense) — 242,505 133,179 Effective rate 0 % 2 % 5 % The Company has tax losses that are available indefinitely for offset against 30% of future taxable profits, as follows: December 31, Description 2021 2020 2019 Tax loss and negative social contribution base, net 8,843,805 5,751,867 1,971,779 Tax loss (25%) 2,210,951 1,437,967 492,945 Negative social contribution base (9%) 795,942 517,668 177,460

PROPERTY AND EQUIPMENT	PROPERTY AND EQUIPMENT 15.1 Accounting policies Property and equipment, including rotable components (replacement parts), 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 statements of operations. 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 of the acquisition cost of the aircraft and related engines. 15.1.1 Sale and leaseback transactions First, 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 financing with the asset given as guarantee. If the requirements related to the performance obligation set out in IFRS 15 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, 2021, the Company carried out a sale and leaseback transaction for two of its own engines. The gain related to this operation corresponds to the amount of R$22,736, recognized in line item “Other costs of services”. 15.1.2 Advance payments for acquisition of aircraft Advance payments for acquisition of aircraft are recorded in property and equipment, including interest and financial charges incurred during the aircraft manufacturing phase and leasehold improvements. During the year ended December 31, 2021, no advances were made for the acquisition of aircraft. 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, establishes the principles for the recognition, measurement, presentation and disclosure of leasing operations and requires that lessees, at the commencement date of the contract, recognize a liability to make payments (a lease liability) 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 in the statements of operations interest expense on the lease liability and depreciation expense for the right-of-use asset. Lessees are also required to reassess the lease liability in the event of certain events, for example, a change in the lease term, 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 value of the lease liability as an adjustment to the right-of-use asset. In determining the discount rate, the Company primarily used as a basis those the funding operations of dates and/or modification of the lease agreements in the Brazilian and North American markets. For operations in the Brazilian market, the Company converted the cost of funding to the equivalent of an operation in US dollars, adjusting this for the country risk and interest rate differential between Brazil and the United States of America. Thus, it was concluded that the built-in inflationary effects are very low, in addition to the fact that 99.5% of the Company’s leasing obligations are denominated in dollars. 16.1.1 Componentization of aircraft At the receipt and initial recognition of aircraft and/or right-of-use assets, the Company allocates the total cost of the aircraft between five major components: airframe, auxiliary power unit (“APU”), landing gear and two engines. The economic useful life is the period extending up to the next heavy maintenance or structural check or the remaining useful life of the aircraft/engines or lease contract, whichever is shorter. 16.1.2 Capitalization of heavy maintenance events The Company has maintenance contracts for its engines that cover all significant maintenance events. Subsequent heavy maintenance events, which increase the useful lives of assets, are capitalized and recognized as property and equipment or in addition to the right of use of assets. They are subsequently depreciated during the respective period of use or until the end of the lease. Repairs and other routine maintenance are recognized in statements of operations during the year in which they are incurred. Additionally, the Company also has “power-by-the-hour” contracts, in which the amounts due to maintenance providers are calculated based on the hours flown, at the time of the maintenance event. 16.1.3 Recognition of contractual obligations relating to return of aircraft (asset retirement obligation) The costs resulting from the maintenance events that will be carried out immediately before the return of the aircraft to the lessors, defined as restoration events, upon the receipt of the aircraft, are recognized at present value, increasing the value of the asset as a balancing item to an obligation, 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. As of December 31, 2021, the Company also recognized provisions for ARO related to engines, according to the accounting practice mentioned in the note 23.1.1 The carrying amount that represents the right of use of aircraft is tested for impairment annually, even if there are no circumstances that indicate the existence of impairment. 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 Finite 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 reflected in the statements of operations for the year in which it was incurred. 17.1.2 Indefinite useful life 17.1.2.1 Goodwill In this category, the amounts related to goodwill arising from the business combinations of IntelAzul S.A. and Azul Conecta are recorded. Goodwill is tested annually by comparing the carrying amount with the recoverable amount of the cash-generating unit. 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 assets. No impairment has been recorded to date. 17.1.2.2 Rights of operations in airports (slots) In the business combinations of IntelAzul S.A. and Azul Conecta, slots acquired were recognized at their fair values at the acquisition date and not amortized. The estimated useful life of these rights was considered indefinite due to several factors and considerations, including requirements and authorizations for permission to operate in Brazil and limited availability of usage rights at the most important airports in terms of air traffic volume. The carrying amount of these rights is assessed annually. No impairment has been recorded to date. 17.2 Breakdown of intangible assets Description Weighted average rate (p.a.)

(formerly Tudo Azul S.A.) in 2012 and Azul Conecta (formerly Two Táxi Aéreo Ltda.) in 2020, respectively, and refers to the consideration transferred, less the fair value of assets acquired and liabilities assumed, net. (b) As part of the allocation of the purchase price for the acquisition of IntelAzul S.A. (formerly Tudo Azul S.A.) and Azul Conecta (formerly Two Táxi Aéreo Ltda.) the Company recognized the value of operating licenses for certain airport slots, asset with an indefinite useful life. (c) The balances of transfers are between the groups of Property and equipment, Right-of-use assets and Intangible assets. 17.3 Impairment of non-financial assets 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. The Company operates a single cash-generating unit. 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. Aircraft and engines in operation are tested for impairment, by comparing the net carrying amount with the fair value indicated by specialized publications. After this comparison, Management concluded that there are no losses related to the right of use recorded in the asset, and therefore no provision for loss on these assets was recorded. As disclosed in Note 1.4 17.3.1 Impairment of intangible assets without a finite useful life As of December 31, 2021, the Company performed annual impairment tests, through the discounted cash flow of the cash-generating unit. The assumptions used in the impairment tests of goodwill and other intangible assets 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. Assumptions and projections are revised and approved by management. 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 on December 9, 2021. 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 impairment test showed that the estimated recoverable amount is greater than the carrying amount allocated to the cash-generating unit and, therefore no adjustment of the recoverable amount to be recorded on December 31, 2021 was identified, as shown below: December 31, 2021 December 31, 2020 Goodwill Slots Goodwill Slots Carrying amount 901,417 126,547 810,948 82,196 Carrying amount – CGU 8,499,312 — 6,410,447 — Value in use 35,355,308 2,419,843 32,227,871 1,726,007 Pre-tax discount rate 9.5 % 10.5 % 10.3 % 8.5 % Growth rate in perpetuity 3.0 % 3.0 % 3.0 % 3.0 %

The Company incurred borrowing costs of R$75,645, which will be amortized over the contract term, as required by IFRS-9.The Company and its subsidiary Azul Linhas Aéreas Brasileiras S.A. will provide irrevocable, unconditional and full guarantee to honor the payment of their obligations related to the debt, and net proceeds from the issue will be used by the Company for corporate purposes in general. 18.3.2 Financing of aircraft and engines The balance consists substantially of the financing of engine maintenance and the purchase of aircraft and engines. Aiming to maintain a prudential and sustainable short-term liquidity position, on March 31, 2021, the Company concluded the renegotiation of its working capital obligation with the United States International Development Finance Corporation (“DFC”), which resulted in a new payment stream, where the short-term debt was extended and, therefore, transferred to long term. Such negotiation did not entail extinguishment of debt instruments, according IFRS-9. 18.3.3 Convertible debentures On November 12, 2020, the Company concluded the public offering for the distribution of debentures convertible into first-issue preferred shares, with security interest and additional personal guarantee of the Company, with the following characteristics: total issue amount: (i) R$1,745,900; (ii) issue date: October 26, 2020; (iii) term and maturity date: 5 years from the date of issue, maturing therefore on October 26, 2025; (iv) conversion price: R$32.2649 per preferred share, resulting in an initial conversion premium of 27.50%, calculated on the VWAP ( Volume Weighted Average Price ) of 30 trading sessions of the reference share of R$25.3058. The issuance of debentures is part of Azul's efforts to contain the economic impact of the COVID-19 pandemic on its operations and the Company expects to use the net proceeds obtained for working capital, expansion of its logistics activities and other strategic opportunities. The debentures are redeemable, totally or partially, in cash at the Company's discretion at any time, after 36 months, if the last price reported for American Depositary Share (ADS) representing Azul's preferred share exceeds 130% of the conversion price for a specific period. The debentures are guaranteed by the Company and its main operating subsidiary, ALAB, and are guaranteed by certain assets, including, but not limited to, intellectual property assets held by the guarantors and the TudoAzul frequent-flyer program, certain rights related to the right of use of the hangar and specific equipment necessary for maintenance of the hangar used by the Company and located at Viracopos airport. As required by IFRS 9 - Financial Instruments, the conversion right was measured at fair value through profit or loss as it is an embedded derivative. Accordingly, during the year ended December 31, 2021, due to the devaluation of the Company’s shares, a gain of R$829,213 was recognized under the “Derivative financial instruments, net” line item (loss of R$755,354 in December, 31 2020). 18.3.4 Senior notes 2024 On October 19, 2017, the subsidiary Azul Investments LLP priced an offering of Senior Notes abroad, with total principal amount of US$400 million, due in 2024 and with a coupon of 5.8750% p.a. This transaction is part of the Company’s liability management strategy the proceeds will be used for refinancing debts and general corporate purposes. 18.3.5 Working capital in foreign currency The balance is comprised substantially of contracts that will be used by the Company for general corporate purposes. 18.4 Schedule of amortization of long-term debt December 31, Description 2021 2020 2022 — 743,137 2023 1,242,042 914,343 2024 2,417,304 2,264,451 2025 1,959,558 2,551,701 2026 3,357,741 13,990 After 2026 18,696 14,560 8,995,341 6,502,182 18.5 Covenants As of December 31, 2021, the Company has loans and financing subject to covenants related to the indebtedness level and the debt service coverage ratio.

Provisions [abstract]
PROVISIONS	PROVISIONS 23.1 Accounting policies 23.1.1 Provision for return of aircraft and engines (asset retirement obligation – ARO) Aircraft and engines negotiated under the lease without purchase option modality regularly provide for contractual obligations establishing conditions for return. In these cases, the Company provides for the 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 is initially recognized at present value in right-of-use assets and the balancing item of the provision for aircraft return 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. 23.1.2 Provision for onerous liability Onerous contract is that in which the unavoidable costs of meeting the contractual obligations exceed the economic benefits expected to be received over the same contract. In these cases, the present obligation under the contract is measured and recognized as a provision. However, before a separate provision for onerous contract is established, the Company assesses and recognizes any impairment loss that has occurred in the assets related to that contract in accordance with IAS 36 – Impairment of Assets. The provision is related to the obligations arising from the fleet transformation plan, as detailed in note 1.4 23.1.3 Provision for tax, civil and labor risks Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of a past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation, and a reliable estimate can be made of the amount of the obligation. The Company is a 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.

RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS 24.1 Compensation of key management personnel 24.1.1 Accounting policies 24.1.1.1 Executive bonus and employee profit sharing The Company’s employees are entitled to profit sharing based on certain goals agreed annually, and executives based on statutory provisions proposed by the Board of Directors and approved by the shareholders. The amount of profit sharing is recognized in statements of operations for the year in which the goals are achieved. Key management personnel comprise the directors, officers and members of the Executive Committee. The compensation and charges paid or payable for services are shown below: December 31, Description 2021 2020 2019 Short-term benefits 30,080 29,792 29,442 Share-based payment plan (a) 13,042 36,986 29,129 43,122 66,778 58,571 (a) Considers stock option plans, restricted shares and phantom shares. The effect on the result referring to the phantom shares is based on the variation of the Company’s share value, which is updated at each reporting period, and does not represent a cash outflow in the current year, with a forecast for settlement in up to eight years. Due to the reduction of the share value in the year ended December 31, 2021, from R$39.30 to R$24.36, there was a decrease in the estimate of remuneration and, consequently, a reversal of the expense recorded in prior periods. 24.2 Guarantees and pledges granted by the Parent Company The Company has granted guarantees on rental properties for some of its executives and the total amount involved is not significant. 24.3 Technology service sharing contract On January 1, 2013, the Company entered into a contract with Águia Branca Participações S.A., one of its shareholders, for the sharing of information technology resources for an indefinite period. The total amount of services acquired during the year ended December 31, 2021 was R$52 (R$51 as of December 31, 2020), recorded under “Other operating income and expenses, net” in the statements of operations. As of December 31, 2021, there were no amounts to be paid as a result of this transaction. 24.4 Ticket sales contract On March 26, 2018, the Company entered into a ticket sales contract with Caprioli Turismo Ltda., a travel agency owned by the Caprioli family (which holds an indirect stake in the Company through TRIP former shareholders), whereby Caprioli Turismo Ltda. is granted a R$20 credit line for the purchase and resale of tickets for flights operated by the Company. This credit line is guaranteed by a non-interest bearing promissory note in the same amount payable. 24.5 Aircraft sublease receivables In December 2019, the Company signed a letter of intent for the sublease of up to 28 aircraft to the Breeze Aviation Group (“Breeze”), an airline founded by the controlling shareholder of Azul, headquartered in the United States.

Earnings per share [abstract]
Loss Per Share	LOSS PER SHARE 26.1 Accounting policies Basic earnings (loss) per share are calculated by dividing profit or loss for the year attributed to the Company's controlling shareholders by the weighted average number of all classes of shares outstanding during the year. Diluted earnings (loss) per share are calculated by adjusting the weighted average number of shares outstanding by instruments potentially convertible into shares. However, due to the losses reported in the years ended December 31, 2021, 2020 and 2019, these instruments issued by the parent 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 statements of operations 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. 26.2 Loss per share calculation Years ended December 31, Description 2021 2020 2019 Numerator Net loss (4,213,208) (10,834,709) (2,403,086) Denominator Weighted average number of common shares 928,965,058 928,965,058 928,965,058 Weighted average number of preferred shares 333,286,277 329,779,360 328,571,282 75 preferred shares (*) 75 75 75 Weighted average number of equivalent preferred shares (*) 345,672,478 342,165,561 340,957,483 Weighted average number of equivalent common shares (**) 25,925,435,858 25,662,417,083 25,571,811,221 Weighted average number of shares outstanding and presumed conversions 63,296,103 63,789,234 9,865,114 Weighted average number of shares that would have been issued at average market price 2,711,861 4,705,897 6,805,600 Basic loss per common share - R$ (0.16) (0.42) (0.09) Diluted loss per common share - R$ (0.16) (0.42) (0.09) Basic loss per preferred share - R$ (12.19) (31.67) (7.05) Diluted loss per preferred share - R$ (12.19) (31.67) (7.05) (*) 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 12,386,200 preferred shares at the conversion ratio of 75 common shares for each preferred share.

SALES REVENUE	SALES REVENUE 28.1. Accounting policies 28.1.1 Passenger, cargo and auxiliary service revenue Passenger revenue is recognized when air transportation is actually provided. Tickets sold but not yet flown are recorded as air traffic liability, representing deferred revenue from tickets sold to be flown on a future date, net of breakage revenue estimate. Breakage revenue consists of calculating, on a historical basis, tickets issued that will expire due to non-use, that is, passengers who have purchased tickets and are very likely not to use them. For the purposes of recognizing this revenue, the average periods for providing air transport services are also considered, and these assumptions are included in a statistical model that determines the estimate of the breakage rate to be adopted. 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 along with the primary passenger transport obligation. 28.1.2 Frequent-flyer program revenue – TudoAzul Under the “TudoAzul” program, customers accrue points based on the amount spent on tickets flown. The amount of points earned depends on TudoAzul membership category, market, fare class and other factors, including promotional campaigns. Through 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. With some exceptions, points generally expire two years after the date earned regardless of activity in the program member's account. Upon the sale of a ticket, the Company recognizes a portion of ticket sales as revenue when the transportation service occurs and defers a portion corresponding to the points earned under the TudoAzul Program, in accordance with IFRS 15 – Revenue from Contracts with Customers. 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 frequent-flyer program points to customers and partners, including credit card companies, financial institutions and retail companies. The related revenue is deferred and recognized as passenger transport revenue when the points are redeemed and the related transport service occurs, based on the weighted average price of the points sold. Points awarded or sold and not used are recorded in “Air traffic liability”. 28.2 Breakdown of sales revenue Years ended December 31, Description 2021 2020 2019 Revenue Passenger revenue 9,101,576 5,197,272 11,198,595 Cargo transport and other revenue 1,301,090 799,222 604,297 Gross revenue 10,402,666 5,996,494 11,802,882 Taxes levied Passenger revenue (290,532) (157,665) (290,696) Cargo transport and other revenue (136,405) (94,703) (69,869) Total taxes (426,937) (252,368) (360,565) Net revenue 9,975,729 5,744,126 11,442,317 Revenues by geographical location are as follows: Years ended December 31, Description 2021 2020 2019 Domestic revenue 8,849,486 4,759,257 9,195,535 Foreign revenue 1,126,243 984,869 2,246,782 Net revenue 9,975,729 5,744,126 11,442,317

FINANCIAL INSTRUMENTS AND RISK MANAGEMENT	FINANCIAL INSTRUMENTS AND RISK MANAGEMENT Operating activities expose the Company and its subsidiaries to financial market risks related to fuel prices, foreign exchange rates, interest rates, credit and liquidity. Such risks can be mitigated through the use of swaps, futures and options, in the oil, US dollar and interest market. The Company’s management monitors the market, credit and liquidity risks. All activities with financial instruments for risk management are carried out by specialists with skill, experience and adequate supervision. It is the Company's policy not to enter into derivative transactions for speculative purposes. 30.1 Accounting classification and fair value hierarchy of financial instruments The accounting classifications of the Company's consolidated financial instruments and fair value hierarchy are shown below: Carrying amount Fair value December 31, December 31, Description Level 2021 2020 2021 2020 Assets Cash and cash equivalents 2 3,073,799 3,064,815 3,073,799 3,064,815 Short-term investments 2 908,149 946,281 908,149 946,281 Accounts receivable — 997,893 875,382 997,893 875,382 Aircraft sublease receivables — 274,198 312,937 274,198 312,937 Security deposits and maintenance reserves — 1,964,419 1,554,042 1,964,419 1,554,042 Derivative financial instruments 2 353,817 428,309 353,817 428,309 Liabilities Loans and financing — (9,381,945) (5,894,515) (8,973,383) (5,414,689) Loans and financing - conversion right 2 (636,786) (1,465,999) (636,786) (1,465,999) Lease liabilities — (14,890,575) (12,520,812) (14,890,575) (12,520,812) Accounts payable — (2,335,165) (2,561,727) (2,335,165) (2,561,727) Accounts payable – supplier finance — (3,694) (157,801) (3,694) (157,801) Reimbursement to customers — (173,686) (221,342) (173,686) (221,342) Insurance premiums payable — (92,793) (52,427) (92,793) (52,427) Derivative financial instruments 2 (287,051) (421,034) (287,051) (421,034) 30.2 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 matures in 10 years from its issue, with annual interest of 3.75% until September 20, 2016 and 7.5% in the following years. The accrued interest shall be paid on the maturity date or until the early redemption of the securities, whichever is earlier. 30.3 Convertible debentures As required by IFRS-9 – Financial Instruments, the conversion right of the convertible debentures was measured at fair value through profit or loss as it is an embedded derivative. Details of this operation are provided in note 18.3.3. 30.4 Derivative financial instruments Derivative financial instruments, and their movements are presented in Note 21 30.5 Market risks During the years ended December 31, 2021, 2020 and 2019, gains and losses were recognized in statements of operations as follows: December 31, Description 2021 2020 2019 Gain (loss) on interest rate risk 48,571 30,949 142,220 Gain (loss) on aviation fuel price risk (“QAV”) 75,075 (1,371,941) 115,189 Gain (loss) on foreign exchange risk (88,675) (74,371) 68,043 34,971 (1,415,363) 325,452 30.5.1 Interest rate risk As of December 31, 2021, the Company had swap contracts to hedge against the effect of fluctuations in interest rates on part of payments for leases. 30.5.2 Aviation fuel price risk (“QAV”) The price of aviation 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, 2021, forward transactions on fuel. 30.5.3 Foreign exchange risk The foreign exchange risk arises from the possibility of unfavorable exchange differences to which the Company's liabilities or cash flows are exposed. The Company constantly monitors the net exposure in foreign currency and evaluates the contracting of derivative transactions, projecting for a period deemed appropriate to minimize its exposure. The exposure to the main exchange differences is as follows: Exposure to US$ Exposure to € December 31, December 31, Description 2021 2020 2021 2020 Assets Cash and cash equivalents and short-term investments 244,239 262,309 911,071 854,462 Accounts receivable 100,640 232,950 — — Security deposits and maintenance reserves 1,918,517 1,540,231 — — Aircraft sublease receivables 274,198 312,937 — — Derivative rights — 155,920 — — Other assets 154,198 60,576 — — Total assets 2,691,792 2,564,923 911,071 854,462 Liabilities Accounts payable (624,162) (831,429) — — Loans and financing (8,506,445) (5,741,253) — — Lease liabilities (14,814,400) (12,463,426) — — Derivative obligations — (81,274) — — Provisions and other liabilities (3,808,012) (951,348) — — Total liabilities (27,753,019) (20,068,730) — — Net exposure (25,061,227) (17,503,807) 911,071 854,462 Net exposure in foreign currency (4,490,857) (3,368,254) 144,134 133,972 30.6 Credit risk Credit risk is inherent to the Company's operating and financial activities, mainly disclosed in cash and cash equivalents, short-term investments, accounts receivable, aircraft sublease receivables, security deposits and maintenance reserves. Financial assets classified as cash and cash equivalents and short-term investments 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. The credit quality of the customer is assessed based on an extensive internal credit rating system. Outstanding receivables from customers are frequently monitored by the Company. 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 has an obligation to assess the risks of counterparties in financial instruments and to diversify the exposure periodically. 30.7 Liquidity risk The maturity schedules of the Company’s consolidated financial liabilities as of December 31, 2021 are as follows: December 31, 2021 Description Carrying amount Contractual cash flows 2022 2023 2024 2025 After 2026 Accounts payable 2,335,165 2,335,165 1,771,663 150,477 191,160 86 221,779 Accounts payable – supplier finance 3,694 3,694 3,694 — — — — Loans and financing 10,018,731 10,143,516 1,039,198 1,298,922 2,443,293 1,978,628 3,383,475 Lease liabilities 14,890,575 28,424,354 3,802,070 4,056,001 4,015,746 3,397,128 13,153,409 Derivative obligations 287,051 287,051 77,509 68,534 141,008 — — Insurances premiums payable 92,793 92,793 92,793 — — — — Reimbursement to customers 173,686 173,686 173,686 — — — — 27,801,695 41,460,259 6,960,613 5,573,934 6,791,207 5,375,842 16,758,663 30.8 Sensitivity analysis of financial instruments 30.8.1 Risk factor: changes in exchange rates As of December 31, 2021, the Company adopted an exchange rate of R$5.5805/US$1.00 and R$6.3210/€1.00, corresponding to the month’s closing rate released by the Central Bank of Brazil as a probable scenario.
