The MPEEM method assumes that the fair value of an intangible asset is the same as the present value of the cash flows attributable to that asset, less the contribution of other assets, both tangible and intangible ones. Business combination – Acquisition of Total Voice Comunicação S.A. (“Total Voice”) On March 1, 2019, Zenvia Brazil acquired all the shares of Total Voice, a company that operates in the telephony API (Application Programming Int erface) business. The Total Voice Communication API allows developers to add voice and text communication directly into their application. The value of the acquisition of Total Voice was R$2,002, paid in cash to former shareholders who left Total Voice on the acquisition date and R$13, paid to former shareholders who remained as employees of the Company, totaling R$2,015. After the acquisition, the former shareholders who remained in the company were subject to an additional remuneration of R$ 13,667 paid in 2021 and up to R$1,301 to be paid in 2022, based on certain conditions, including the continuation of the employment relationship with the Company. As of December 31, 2021, a provision in the amount of R$1,301 (R$ 13,112 and R$5,230 as of December 31, 2020 and 2019 respe The bargain purchase gain arising from the acquisition was recognized as follows: Total Voice December 31, 2019 Consideration transferred 2,215 Other net assets, including PPE and cash 57 Intangible assets –– Customer portfolio (a) 518 Intangible assets –– Digital platform (b) 3,919 Gain for bargain purchase 2,479 Taxes on bargain purchase (843 ) Net amount for bargain purchase 1,636 The gain on bargain purchase, recorded in a separate caption in the statement of profit or loss, resulted from the fact that most of the compensation of the former shareholders that remained as employees is to be paid in form of future compensation, linked to continuous employment. Current tax legislation allows deductibility of the fair value of net assets acquired when a non-substantive action is taken after the acquisition by the Company and, therefore, the tax and accounting basis of the net assets acquired are equal to the acquisition date. In this regard, for the acquired businesses where the Company considers merging the acquiree, with the right to deductibility of the amortization or depreciation of the net assets acquired, no deferred income tax was recorded in these financial statements on the acquisition date. (a) The fair value of R$518 includes the effect of allocation of the customer portfolio owned by the company before the acquisition, calculated based on the discounted cash flow. (b) The fair value of R$3,919 includes the effect of allocating the capacity to generate future revenue according to the potential of the existing platform, calculated based on the discounted cash flow. The assessment techniques are summarized below: Acquired assets evaluation technique Intangible asset – Allocation of the costumer portfolio and digital platform Income Approach: The GEMP Method (Multi-Period Excess Earnings) assumes that the fair value of an intangible asset is equal to the present value of the cash flow attributable to that asset, less the contribution of other assets, tangible or intangible. COVID-19 As a result of the global outbreak of COVID-19, unprecedented economic uncertainties have arisen that continue to have an adverse impact on global economic and market conditions, including in Brazil. In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic, and the Brazilian Federal Government declared a national emergency regarding COVID-19. In addition The global impact of the COVID-19 outbreak has evolved rapidly and presents material uncertainty and risk r egarding the Company’s future performance and financial results. In response to the COVID-19 outbreak, the Company has implemented a number of measures aimed at safeguarding the health of employees and the stability of operations, including: (1) the implem entation of a telecommuting regime; (2) restrictions on all business travel and the postponement or cancellation of other planned events or their shift to virtual-only experiences; and (3) the provision of a utility grant to assist employees with the incre The COVID-19 pandemic is also having an impact on the behavior of the Company’s customers (and potential customers) as it is accelerating its digitization plans

Preparation basis
Preparation basis	3 Preparation basis These consolidated financial statements have been prepared in accordance with International Financial Reporting Standard (IFRS) as issued by the International Accounting Standards Board (IASB). In May 2021, the Group completed its Corporate Reorganization process, whereby a new holding company, located in the Cayman Islands, became the direct and indirect controlling entities of the Group and the shareholders and its voting and non-voting interest are the same before and after the restructuring. On May 7, 2021, Zenvia Mobile Serviços Digitais S.A (Zenvia Brazil) an operating company, was the ultimate holding of the Group, and it consolidated the results of all companies until that date. The Group accounted for the restructuring as a business combination of entities under common control , and the pre-combination carrying amounts of Zenvia Brazil are included in the Company consolidated financial statements with no fair value uplift. The issuance of these financial statements was approved by the Executive Board of Di rectors on March 31, 2022. Measurement basis The financial statements were prepared based on historical cost, except for certain financial instruments measured at fair value and contingent consideration for business combinations, as described in the following accounting practices. See item (d) below for information on the measurement of financial information of subsidiaries located in hyperinflationary economies. Functional a nd presentation currency These consolidated financial statements are presented in Brazilian Real, which is the Company’s functional currency. All amounts have been rounded to the nearest thousands, except if otherwise indicated. The functional currency o f the subsidiary Rodati Motors Corporation is the US Dollar. The indirect subsidiaries of the Company have the following functional currencies: Rodati Motors Central de Informações de Veículos Automotores Ltda. has the local currency, Brazilian Real (BRL), as its functional currency; Rodati Services S.A. has the local currency, Argentinean Peso (ARG), as its functional currency; and Rodati Servicios, S.A. de CV. has the local currency, Mexican Pesos (MEX), as its functional currency. Foreign currency tran slation For the consolidated Group companies in which functional currency is different from the Brazilian Real, the financial statements are translated to Real as of closing date. Monetary assets and liabilities denominated in foreign currencies are trans lated into the functional currency at the exchange rate at the reporting date. Non-monetary assets and liabilities that are measured at fair value in a foreign currency are translated into the functional currency at the exchange rate when the fair value wa s determined. Non-monetary items that are measured based on historical cost in a foreign currency are translated at the exchange rate at the date of the transaction. Foreign currency differences are generally recognized in profit or loss and presented with in finance costs. Accounting and reporting in highly hyperinflationary economy In July 2018, considering that the inflation accumulated in the past three years in Argentina was higher than 100%, the adoption of the accounting and reporting standard in hyperinflationary economy became mandatory in relation to the subsidiary Rodati Ser vices S.A., located in Argentina. Non-monetary assets and liabilities, the equity, and the statement of income of subsidiaries that operate in hyperinflationary economies are adjusted by the change in the general purchasing power of the currency, applyin g a general price index. The financial statements of an entity whose functional currency is the currency of a hyperinflationary economy, whether they are based on the historical or current cost approach, should be expressed in terms of the current measure ment unit at the balance sheet date and translated into Real at the closing exchange rate for the period. The impacts of changes in general purchasing power were reported as finance costs in the statements of profit or loss of the Company. Use of estimates and judgments In preparing these consolidated financial statements, management has made judgements and estimates that affect the application of the Group’s accounting policies and the reported amounts of assets, liabilities, income, and expenses . Actual results may differ from these estimates. Estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to estimates are recognized prospectively. Judgments: Information about judgments referring to the adoption of accounting policies which impact significantly the amounts recognized in the financial statements are included in the following notes: Note 1 – Identification of assets acquired and liabilities assumed. Note 11 - Intangible assets: determination of useful lives of intangible assets. Uncertainties on assumptions and estimates: Information on uncertainties as to assumptions and estimates that pose a high risk of resulting in a material adjustment within the next fiscal year are included in the following notes: Note 7 – Allowance for expected losses: main assumptions in the determination of loss rate. Note 11 - Impairment test of intangible assets and goodwill: assumptions regarding projections of generation of future cashflows. Note 15 - Provision for labor, tax and civil risks: main assumptions regarding the likelihood and magnitude of the cash outflows. Note 1 – business combination: assumptions on the determination of fair value of consideration transferred, assets acquired, and liabilities assumed. The identification of the intangible assets acquired in the business combinations f. Measurement of fair value A series of Company’s accounting policies and disclosures requires the measurement of fair value, for financial and non-financial assets and liabilities. The Company established a control structure related to measurement of fair value. It includes the review process of all significant fair value measurements, reporting directly to the Chief Fin ancial Officer. Evaluation process includes the regular review of significant non-observable data and valuation adjustments. If third-party information, such as brokerage firms’ quotes or pricing services, is used to measure fair value, then the evaluatio n process analyzes the evidence obtained from the third parties to support the conclusion that such valuations meet the IFRS requirements, including the level in the fair value hierarchy in which such valuations should be classified. Significant assessment matters are reported to the Board of Directors. When measuring fair value of an asset or liability, the Company uses observable data as much as possible. Fair values are classified at different levels according to hierarchy based on information (inputs) used in valuation techniques, as follows: Level 1: Prices quoted (not adjusted) in active markets for identical assets and liabilities. Level 2: Inputs, except for quoted prices, included in Level 1 which are observable for assets or liabilities, directly (prices) or indirectly (derived from prices). Level 3: Inputs, for assets or liabilities, which are not based on observable market data (non-observable inputs). The Company recognizes transfers between fair value hierarchy levels at the end of the fi nancial statements’ period in which changes occurred.

Significant accounting policies
Significant accounting policies	4 Significant accounting policies g. Basis of Consolidatio (i) Busines s Combination The Company accounts for business combinations using the acquisition method when the acquired set of activities and assets meets the definition of a business and control is transferred to the Company. When determining whether a particular se t of activities and assets is a business, the Company assesses whether the acquired set of assets and activities includes, at a minimum, an input and a substantive process and whether the acquired set has the ability to produce outputs. The Company has the option of applying a "concentration test" that allows for a simplified assessment of whether an acquired set of activities and assets is not a business. The optional concentration test is met if substantially all of the fair value of gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. The consideration transferred on acquisition is generally measured at fair value, as are the identifiable net assets acquired. Any goodwill that arises is tested ann ually for impairment. Any gain on a bargain purchase is recognized in profit or loss immediately. Transaction costs are recognized as expenses when incurred unless they relate to the issuance of debt or equity securities. The consideration transferred doe s not include amounts referring to the settlement of pre-existing relationships. These amounts are generally recognized in profit or loss. Any contingent consideration is measured at fair value on the acquisition date. If a contingent consideration payabl e meets the definition of a financial instrument, it is classified as equity, is not revalued and the settlement is accounted for in equity. Otherwise, another contingent consideration is remeasured to fair value at each reporting date and subsequent chang es in the fair value of the contingent consideration are recognized in profit or loss. (ii) Subsidiaries Subsidiaries are entities controlled by the Company. The Company ‘controls’ an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. The financial statements of subsidiaries are included in the consolidated financial statements from the date on which control begins until t he date on which control ceases. (iii) Principles of consolidation The consolidated financial statements include the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated. h. Foreign currency (i) Transactions in foreign currency Transactions in foreign currency, that are, all those not carried out in the functional currency, are translated at the exchange rate on the dates of each transaction. Monetary assets and liabilities in foreign currency are translated into the functional currency at the exchange rate on the closing date. Gains and losses from changes in exchange rates on monetary assets and liabilities are recognized in the income statement. i. Segment reporting The segment reporting is based on information used by the Company's Chief Operating Decision Maker (CODM) represented by the Chief Executive Officer. CODM considers the entire Group as a single operating and re portable segment, monitoring operations, making decisions on resource allocation, and evaluating performance based on a single operating segment. CODM analyzes the relevant financial data on a combined basis for all subsidiaries. j. R evenue The Company primarily generates revenue from the cloud-based platform that allows organizations to integrate various communication features (including short message service - SMS, WhatsApp, Voice, WebChat, and Facebook Messenger) into their softwa re applications. Revenues are generated by the number of interactions the Company's customers have with their own customers, based on prices defined in the contracts. Performance obligations and revenue recognition policies The following table provides information about the nature and timing of satisfaction of performance obligations in customer contracts, including significant payment terms, and related revenue recognition policies. Type of Services Nature and timing of satisfaction of performance obligations, including significant payment terms Revenue recognition policy Communication Platform The Company's revenue derives mainly from fees based on the use of services available on its communication platform. Use of these services is measured by individual volume and revenues based on these volumes are recognized over the period of use. The Company provides services to customers with prepaid contracts and term contracts for a fixed or indefinite period. Small customers and customers who pay by credit card are billed in advance, while large customers are billed monthly on the postpaid model. Collections are made within thirty days of billing. Customers who pay in the prepaid model, withdraw their balances as they use the Company’s products. Revenue is recognized when control of services is transferred to customers ins an amount that reflects the consideration we expect to receive in exchange for those products or services. Revenue is recognized net of any taxes levied on customers, which are subsequently remitted to government authorities. Invoiced amounts are recorded in accounts receivable and in revenue or advances from customers, depending on whether the revenue recognition criteria are met. The company's agreements with customers do not provide rights of return, and do not provide customers with the right to take possession of the software that supports the applications. Carrier billing Carrier billing is a business model in which there is a provider that makes its content available through the connections that the Company maintains with carriers (telephone operators), which provide the service to the final consumer. The provider is responsible for the content as well as the price. The Company acts as an agent in the process, receiving the amounts collected by the connections and passing on the respective amounts to the providers. Therefore, net revenue is accounted for at the fee charged to content providers for the service. The carrying billing business is characterized as an operation in which the Company has contracts with mobile operators in Brazil and providers of information content through digital platforms, on which end customers of mobile telephony operators can subscribe to the content of the operators and receive information based on their cell phones. In this operation, the Company bills mobile operators and transfers it to content providers, receiving a fee for performing this service. Revenue is recognized when content providers deliver services to end customers. Zenvia recognizes revenue at the amount of net fees to be received on these transactions. k. Financial instruments (i) Initial recognition and measurement Trade accounts receivable and debt securities issued are initially recognized on the date they were originated. All other financial assets and liabilities are initially recognized when the Company becomes party to the contractual provisions of the instrument. A financial asset (unless it is a trade receivable without a significant financing component) or financial liability is initially measured at fair value plus, for an item not measured at fair value through profit or loss (FVTPL), the transaction costs that are directly attributable to their acquisition or issuance. Accounts receivable from customers without a significant financing component are initially measured at the transaction price. (ii) Classification and subsequent measurement Upon initial recognition, a financial asset is classified as measured: at amortized cost or at fair valu e through profit or loss (FVTPL). Financial assets are not reclassified subsequent to initial recognition, unless the Company changes the business model for managing financial assets, in which case all affected financial assets are reclassified on the first day of the reporting period following the change in business model. A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as measured at FVTPL: - is held within a business model whose objective is to hold financial assets in order to receive contractual cash flows; and - its contractual terms generate, on specific dates, cash flows that are related only to the payment of principal and interest on the outstanding principal amount. The Company carries out an assessment of the purpose of the business in which a financial asset is held in the portfolio, as this better reflects the way in which the business is managed and the information is provided t o management. Financial assets held for trading or managed with performance evaluated based on fair value are measured at fair value through profit or loss. (iii) Financial assets – assessment of whether contractual cash flows are principal and interest paymen ts only For purposes of this assessment, 'principal' is defined as the fair value of the financial asset at initial recognition. ‘Interest’ is defined as consideration for the time value of money and the credit risk associated with the principal amount ou tstanding over a given period of time and for other basic borrowing risks and costs, as well as a profit margin. The Company considers the contractual terms of the instrument to assess whether the contractual cash flows are only payments of principal and interest. This includes assessing whether the financial asset contains a contractual term that could change the timing or amount of contractual cash flows such that it would not meet that condition. When making this assessment, the Company considers: contingent events that change the value or timing of cash flows; terms that may adjust the contractual rate, including variable rates; prepayment and extension of the deadline; and the terms that limit the Company's access to cash flows from specific assets. Prepayment is consistent with principal and interest payment criteria if the prepayment amount represents, for the most part, unpaid principal and interest amounts on the outstanding principal amount - which may include additional compensation reasonable for early termination of the contract. In addition, with respect to a financial asset acquired for an amount less than or greater than the face value of the contract, the permission or requirement of prepayment for an amount that re presents the face value of the contract plus contractual interest (which also may include reasonable additional compensation for early termination of the contract) accrued (but not paid) are treated as consistent with these criteria if the fair value of th e prepayment is negligible on initial recognition. Financial assets at FVTPL These assets are subsequently measured at fair value. Net income, including interest or dividend income, is recognized in profit or loss. Financial assets at amortized cost These assets are subsequently measured at amortized cost using the effective interest method. Amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized in profit or loss. Any gain or loss on derecognition is recognized in profit or loss. l. Reduction to recoverable value (impairment) Non-derivative financial Assets (i) Financial instruments and contractual assets The Company recognizes provisions for expected credit losses on: financial assets measured at amortized cost. The Company measures the provisions for loss at an amount equal to the lifetime expected credit loss, except for the items described below, which are measured as 12-month expected credit loss: debt securities with low credit risk at the balance sheet date; and - other debt securities and bank balances for which the credit risk has not increased significantly since initial recognition. Provisions for losses on trade accounts receivable and contract assets are m easured at an amount equal to the expected credit loss over the entire life of the instrument. In determining whether the credit risk of a financial asset has increased significantly since the initial recognition and when estimating the credit loss, the C ompany considers reasonable and supportable information that is relevant and available without undue cost or effort. This includes both quantitative and qualitative information and analysis, based on the Company's historical experience and informed credit asses sment, which includes forward-looking information. The Company assumes that the credit risk of a financial asset has increased significantly if it is more than 30 days past due. The Company considers a financial asset to be in default when: the debtor is unlikely to pay its credit obligations to the Company in full, without recourse to actions such as obtaining collateral (if any); or the financial asset is more than 180 days past due. Lifetime credit loss expectations are those that result f rom all possible standard events over the expected life of a Financial Instrument. The 12-month credit loss expectations are the portion that result from possible default events within 12 months after the reporting date (or a shorter period if the expected useful life of the instrument is less than 12 months). The maximum period considered when estimating expected credit loss is the maximum contractual period over which the Company is exposed to credit risk. (ii) Measurement Expect credit loss are a probability-weighted of credit losses. Credit losses are measured as the present value of all cash shortfalls. (iii) Presentation of the provision for expected credit loss in the financial statements Provisions for losses on financial assets measur ed at amortized cost are deducted from the gross carrying amount of the assets. (iv) Write offs The gross carrying amount of a financial asset is written off when the Company does not have reasonable expectations of recovering all or part of a financial asset. The Company does not expect a significant recovery of the amount written off. However, written-off financial assets may still be subject to collection actions to comply with the Company's procedures for recovering amounts due. (v) Non-Financi al Assets At each reporting date, the Company reviews the book values ​​of its non-financial assets (customer portfolio, platform, property, plant and equipment) to determine whether there is any indication of impairme nt. If such an indication exists, the n the asset 's recoverable amount is estimated. For impairment tests, assets are grouped into the smallest asset group that generates cash inflows from continuing use that are largely independent of cash inflows from other assets. Goodwill is allocated to cash-generating units (CGU) for impairment testing purposes. The allocation is made to the cash-generating units or groups of cash-generating units that are expected to benefit from the business combination from which the goodwill originated. Units or groups of units are identified at the lowest level at which goodwill is monitored for internal management purposes, not considered as report segments. Goodwill is tested for impairment annually as at December 31 and when circumstances indicate that the carrying value may be impaired. Impairment is determined for goodwill by assessing the recoverable amount of the segment to which the goodwill relates. Whe n the recoverable amount is less than the carrying amount, an impairment loss is recognized. Impairment losses relating to goodwill cannot be reversed in future periods. m. Property, plant and equipment (i) Recognition and measurement Property, plant, and equipment items are measured at historical acquisition or construction cost, less accumulated depreciation and accumulated impairment losses, if applicable. Cost includes expenses that are directly attributable to the acquisition of an asset. Gains and l osses on the sale of an item of property, plant and equipment are determined by comparing the proceeds from the sale with the book value of the property, plant, and equipment, and are recognized net within other income in the statement of profit or loss. (ii) Subseque nt costs The replacement cost of a component of property, plant and equipment is recognized in the carrying amount of the item if it is probable that the economic benefits embodied within the component will flow to the Company and its cost can be measured reliably. The carrying amount of the component that has been replaced by another is written off. The day-to-day maintenance costs of property, plant and equipment are recognized as expenses in the statements of profit or loss as incurred . (iii) Depreciation Depre ciation is recognized in profit or loss based on the straight-line method based on the estimated useful life of each component, since this method is the one that most closely reflects the pattern of consumption of future economic benefits embodied in the a sset. Deprecia tion methods, useful lives and residual values ​​are reviewed at each reporting date and adjusted, if appropriate. n. Intangible asset (i) Initial recognition Intangible assets that are acquired by the Company and that have defined useful lives are meas ured at cost, less accumulated amortization, and any accumulated impairment losses. (ii) Subsequent expenses Subsequent expenditures are capitalized only when they increase the future economic benefits embodied in the specific asset to wh ich they relate. All other expenses are recognized in profit or loss as incurred. (iii) Amortization Amortization is calculated to lower the cost of intangible assets, less their estimated residual values, using the straight-line method over their estimated useful lives and is recognized in profit or loss. Goodwill is not amortized. (iv) Intangible assets - Research and development expenses Expenses with research activities are recognized as an expense in the period in which they are incurred. Interna lly generated intangible assets resulting from development expenditures (or a development phase of an internal project) are recognized if, and only if, all of the following conditions are demonstrated: • The technical feasibility of completing the intangible asset so that it is available for use or sale. • The intention to complete the intangible asset and use or sell it. • The ability to use or sell the intangible asset. • How the intangible asset will generate probable future economic benefits. • The availability of adequate technical, financial, and other resources to complete the development of the intangible asset and to use or sell it. • The ability to reliably measure the expenses attributable to the intangible asset during its development. The initially recogni zed amount of internally generated intangible assets corresponds to the sum of expenses incurred since when the intangible asset started meeting the recognition criteria. Appropriation is based on employee time records allocated to these developments at t he cost of these employees. When no internally generated intangible asset can be recognized, development costs are recognized in profit or loss for the period when incurred. Subsequent to initial recognition, internally generated intangible assets are re corded at cost, less accumulated amortization, and impairment losses. (v) Goodwill Goodwill resulting from a business combination is stated at cost on the date of the business combination, net of accumulated impairment losses, if any. o. Income tax and social contribution For the entities domiciled in Brazil, the current and deferred income and social contribution taxes are calculated based on the rates of 15% plus a surcharge of 10% on taxable income in excess of Brazilian Reais (BRL) 240% per annum for income tax and 9% on taxable income for so cial contribution on net income and consider the offsetting of tax loss carryforward and negative basis of social contribution limited to 30% of the taxable income. Income taxes applicable to the subsidiary located in the United States are calculated at a rate of 21% of taxable income for the year. For the subsidiaries in Mexico and Argen tina, the current income taxes are calculated based on the rate of 30%. Current and deferred taxes are recognized in profit or loss unless they are related to the business combination, or items directly recognized in shareholders' equity. (i) Current tax Current tax is the estimated tax payable or receivable on taxable income or loss for the year and any adjustment to taxes payable with respect to prior years. It is measur ed based on the tax rates enacted or substantively enacted at the balance sheet date. Among the existing tax incentives in Brazil , the Company uses the benefit arising from the “Lei do Bem” (Law No. 11,196/05), aimed at companies that carry out resea rch and development (R&D) of technological innovation. This benefit provides tax savings by reducing the income tax and social contribution tax base from 60% to 80% of R&D expenditures. (ii) Deferred tax Deferred tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for accounting purposes and the corresponding amounts used for taxation purposes. A deferred income tax and social contribution asset is recognized in relation to unused tax loss es, tax credits and deductible temporary differences, to the extent that it is probable that future taxable profits will be available against which they will be used. Deferred income tax and social contribution assets are reviewed at each balance sheet dat e and are reduced to the extent that their realization is no longer probable. Deferred tax is measured based on the rates that are expected to apply to temporary differences when they are reversed, based on the rates that were enacted or substantively enacted up reporting date. The measurement of deferred tax reflects the tax consequences that would follow the manner in which the Company expects to recover or settle the carrying amount of its assets and liabilities. Deferred i ncome tax and social contribution assets are reviewed at the reporting dates and will be reduced to the extent that their realization is no longer probable. p. Provisions A provision is recognized in the statement of financial position when the Company has a legal or constru ctive obligation as a result of a past event, and it is probable that an outflow of economic benefits will be required to settle the obligation. Provisions are recorded based on the best estimates of the risk involved. The Company sets up provisions to co ver future disbursements that may arise from tax, labor and civil proceedings in progress. Provisions are set up based on the analysis of legal proceedings in progress and on the prospect of an unfavorable outcome, implying a future disbursement. Contingent assets are not recognized until the actions are finalized with a definitive favorable position for the Company and when it is virtually certain that it will realize the asset. The taxes whose enforceability is being questioned in the judicial sphere are r ecorded taking into account the concept of “legal obligation”. Judicial deposits made in guarantee of ongoing lawsuits are recorded under “Judicial Deposits” (see note 16 Provisions are reassessed at the dates of the financial statements and adjusted to reflect the best current estimate. If it is no longer probable that an outflow of resources will be required to settle the obligation, the provision is reversed. q. Share capital The incremental costs directly attributable to the issuance of new shares o r options are shown in equity as a deduction from the amount raised, net of taxes. The capital is composed of 41,324,506 common shares. Capital increases are allowed by resolution of the Board of Directors independently of amendment to its bylaws up to the limit of 1,000,000,000 new nominative common shares with no nominal value. r. Financial income and financial expenses Financial income includes interest income, income from investments, exchange gains on the variation of assets and liabilities indexed in foreign currency. Interest income is recognized in income using the effective interest method. Financial expenses include interest expenses on loans and exchange losses on the variation of assets and liabilities indexed in foreign currency. Borrowing costs that are not directly attributable to the acquisition, construction or production of a qualifying asset are accounted for in profit or loss using the effective interest method. s. Employee benefits Profit sharing and bonuses – Employees' profit sharing and variable compensation for executives are linked to the achievement of operational and financial goals. The Company recognizes liabilities and related expenses, which are allocated to costs of services and administrative expenses, when the goals are probable to be met.

Impairment The Company performed impairment tests for goodwill as of December 31, 2021, as follows: Significant unobservable inputs Relationship between significant unobservable inputs and measurement of the present value of cash flows The present value of cash flows could increase (decrease) if: A nnual forecast revenue growth rate; Forecast of the growth rate of variable input costs; Risk-adjusted discount rate. the annual growth rate of revenue was higher (lower); the cost growth rate was (higher) lower; the risk-adjusted discount rate was (higher) lower. The recoverable amount is determined by calculating the present value of cash flows based on the Company's economic / financial projections for the next 5 years, and a terminal growth rate thereafter. Any kind of reasonably possible change in the key assum ptions on which the recoverable amount is based would not cause the carrying amount to exceed the recoverable amount. 2021 2020 2019 Weighted average annual revenue growth 38.10% 36.38% 16.48% Weighted average annual growth of variable cost 30.29% 26.93% 18.74% Weighted average cost of capital (WACC) 14.73% 16.40% 15.90% Growth in terminal value 0% 0% 0% The key assumptions used in the estimation of the recoverable amount are set out above. The values assigned to the key assumptions represent management’s assessment of future trends for the business and have been based on historical experience and projections of growth, based on internal and external data. The estimated recoverable amount exceeded its c arrying amount by R$ 2,026,583 (2020: R$ 661,000 ) therefore there is no provision for impairment to be recognized . Management has identified that a reasonably possible change in the revenues could cause the carrying amount to equal the recoverable amount. The following table shows the rate of revenue growth and the corresponding effect on the variable cost growth by which the estimated recoverable amount is equal to the carrying amount. 2021 2020 2019 Weighted average annual revenue growth 30.29% 30.62% 9.40% Weighted average annual growth of variable cost 24.29% 21.12% 11.52% An impairment loss in respect of goodwill is not reversed. For other assets, an impairment loss is reversed only to the extent that the asset’s carrying amount does not exceed the carrying amount that would have been determined, net of depreciation or amortization, if no impairment loss had been recognized.

The Company has no level 3 financial instruments. 2021 2020 Fair value through profit or loss Amortized cost Level 1 Level Fair value through profit or loss Amortized cost Level 1 Assets Cash and cash equivalents 346,759 235,472 346,759 - 46,880 13,099 47,453 Interest earnings bank deposits 7,005 - 7,005 - 2,227 - 2,227 Trade accounts receivable - 142,407 - - - 86,009 - Derivative financial instruments 74 - - 74 - - - 353,838 377,879 353,764 74 49,107 99,108 49,680 Liabilities Loans and financing - 208,138 - - - 98,975 - Trade and other payable - 145,360 - - - 101,388 - - 353,498 - - - 200,363 - The Company policy is to recognize transfers into and out of fair value hierarchy levels as of the end of the reporting period. • Level 1: The fair value of financial instruments traded in active markets (such as publicly traded derivatives, and equity securities) is based on quoted market prices at the end of the reporting period. The quoted market price used for financial assets held by the Group is the current bid price. These instruments are included in level 1. • Level 2: The fair value of financial instruments that are not traded in an active market (for example, over-the-counter derivatives) is determined using valuation techniques that maximize the use of observable market data and rely as little as possible on entity-specific estimates. If all significant inputs required to fair value an instrument are observable, the instrument is included in level 2. • Level 3: Inputs for the asset or liability that are not based on observable market data (unobservable inputs). 26.2 Financial risk management The main financial risks to which the Company and its subsidiaries are exposed when conducting their activities are: a) Credit risk It results from any difficulty in collecting the amounts of services provided to the customer s. The Company and its subsidiaries are also subject to credit risk from their interest earning bank deposits. The credit risk related to the provision of services is minimized by a strict control of the customer base and active delinquency management by means of clear policies regarding the concession of services. There is no concentration of transactions with customers and the default level is historically very low. In connection with credit risk relating to financial institutions, the Company and its su bsidiaries seek to diversify such exposure among financial institutions. b) Credit risk exposure The book value of financial assets represents the maximum credit exposure. The maximum credit risk exposure on financial information date was: 2021 2020 2019 Cash and cash equivalents 582,231 59,979 12,342 Interest earnings bank deposits 7,005 2,227 3,292 Trade accounts receivable 142,407 86,009 62,136 731,643 148,215 77,770 The Company determines its allowance for expected credit losses by applying a loss rate calculated on historical effective losses on sales. Additionally, the Company considers that accounts receivable had a significant increase in credit risk and provide s for: All notes receivable past due for more than 6 Notes subject to additional credit analysis presenting indicators of significant risks of default based on ongoing renegotiations, failure indicators or judicial recovery ongoing processes and customers with relevant evidence of cash deteriorating situation. c) Market risk Interest rate and inflation risk: Interest rate risk arises from the portion of debt and interest earning bank deposits remunerated at CDI (Interbank Deposit Cer tificate) rate, which may adversely affect the financial income or expenses in the event an unfavorable change in interest and inflation rates takes place. d) Operation with derivatives The Company uses derivative financial instruments to hedge against the risk of change in the foreign exchange rates. Therefore, they are not speculative. The derivative financial instruments designated in hedge operations are initially recognized at fair value on the date on which the derivative contract is executed and are subsequently remeasured to their fair value. Changes in the fair value of any of these derivative instruments are immediately recognized in the statement of profit or loss under “net financial cost”. e) Liquidity risk T he liquidity risk consists of the risk of the Company not having sufficient funds to settle its financial liabilities. The Company’s and its subsidiaries’ cash flow and liquidity control are monitored on a daily basis by Company treasury function, so as to ensure that cash operating generation and previous fund raising, as necessary, are sufficient to maintain payment schedule, thus not generating liquidity risk for the Company and its subsidiaries. We present below the contractual maturities of financial liabilities including payment of estimated interest.

The Company’s financial instruments are represented by cash and cash equivalents, accounts receivable, accounts payable, loans and financing, and are recorded at amortized cost, plus interes ts incurred. Investments indexed to CDI are recorded at market value, according to quotations published by the respective financial institutions, and the remainder refer mostly to bank deposit certificates. Therefore, the recorded amount of these securities does not differ from the market value. The table below presents three scenarios for the risk of decreasing or increasing of the CDI indexes. According to the projections disclosed by financial institutions, the average rate for CDI is 11.50% p.a., which was defined as a probable scenario (scenario I). Based thereon, variations of 25% (scenario II) and 50% (scenario III) were calculated. The Company has loans and borrowings linked to the CDI rate in 2021 2020 Operation Balance at December 31, 2021 Risk Scenario I Base scenario Scenario II Scenario III Financial investments 346,759 CDI decrease 39,877 29,908 19,939 11.50% 8.63% 5.75% Financial liabilities - financing 208,138 CDI increase (23,936 ) (29,920 ) (35,904 ) 11.50% 14.38% 17.25% g) Capital management The Company´s policy is to maintain a strong capital base to secure investor, creditor, and market confidence and also to sustain future development of the business. Management monitors the return on capital, as well as the dividend yield to ordinary shareholders. The Company controls its capital structure by adjusting and adapting it to current economic conditions. To keep this structure adjusted, the Company may pay dividends, return capital to shareholders, raise new loans, issue promissory notes, and enter into derivative transactions. The Company considers within the net debt structure: loans and financing, less cash, and cash equivalents. The financial leverage ratios as of December 31, 2021 , December 31, 202 0, and December 31, 20 19 can be summarized as follows: 2021 2020 2019 Loans and borrowings 208,138 98,975 63,346 Cash and cash equivalents (582,231 ) (59,979 ) (12,342 ) Net debt (374,093 ) 38,996 51,004 Total equity 1,203,202 115,348 99,337 Net debt/equity (%) (0.31 ) 0.34 0.51

Basis of Consolidation	g. Basis of Consolidatio (i) Busines s Combination The Company accounts for business combinations using the acquisition method when the acquired set of activities and assets meets the definition of a business and control is transferred to the Company. When determining whether a particular se t of activities and assets is a business, the Company assesses whether the acquired set of assets and activities includes, at a minimum, an input and a substantive process and whether the acquired set has the ability to produce outputs. The Company has the option of applying a "concentration test" that allows for a simplified assessment of whether an acquired set of activities and assets is not a business. The optional concentration test is met if substantially all of the fair value of gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. The consideration transferred on acquisition is generally measured at fair value, as are the identifiable net assets acquired. Any goodwill that arises is tested ann ually for impairment. Any gain on a bargain purchase is recognized in profit or loss immediately. Transaction costs are recognized as expenses when incurred unless they relate to the issuance of debt or equity securities. The consideration transferred doe s not include amounts referring to the settlement of pre-existing relationships. These amounts are generally recognized in profit or loss. Any contingent consideration is measured at fair value on the acquisition date. If a contingent consideration payabl e meets the definition of a financial instrument, it is classified as equity, is not revalued and the settlement is accounted for in equity. Otherwise, another contingent consideration is remeasured to fair value at each reporting date and subsequent chang es in the fair value of the contingent consideration are recognized in profit or loss. (ii) Subsidiaries Subsidiaries are entities controlled by the Company. The Company ‘controls’ an entity when it is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. The financial statements of subsidiaries are included in the consolidated financial statements from the date on which control begins until t he date on which control ceases. (iii) Principles of consolidation The consolidated financial statements include the Company and its wholly owned subsidiaries.

Foreign currency (i) Transactions in foreign currency Transactions in foreign currency, that are, all those not carried out in the functional currency, are translated at the exchange rate on the dates of each transaction. Monetary assets and liabilities in foreign currency are translated into the functional currency at the exchange rate on the closing date. Gains and losses from changes in exchange rates on monetary assets and liabilities are recognized in the income statement.
Segment reporting	i. Segment reporting The segment reporting is based on information used by the Company's Chief Operating Decision Maker (CODM) represented by the Chief Executive Officer. CODM considers the entire Group as a single operating and re portable segment, monitoring operations, making decisions on resource allocation, and evaluating performance based on a single operating segment. CODM analyzes the relevant financial data on a combined basis for all subsidiaries.
Revenue	j. R evenue The Company primarily generates revenue from the cloud-based platform that allows organizations to integrate various communication features (including short message service - SMS, WhatsApp, Voice, WebChat, and Facebook Messenger) into their softwa re applications. Revenues are generated by the number of interactions the Company's customers have with their own customers, based on prices defined in the contracts. Performance obligations and revenue recognition policies The following table provides information about the nature and timing of satisfaction of performance obligations in customer contracts, including significant payment terms, and related revenue recognition policies. Type of Services Nature and timing of satisfaction of performance obligations, including significant payment terms Revenue recognition policy Communication Platform The Company's revenue derives mainly from fees based on the use of services available on its communication platform. Use of these services is measured by individual volume and revenues based on these volumes are recognized over the period of use. The Company provides services to customers with prepaid contracts and term contracts for a fixed or indefinite period. Small customers and customers who pay by credit card are billed in advance, while large customers are billed monthly on the postpaid model. Collections are made within thirty days of billing. Customers who pay in the prepaid model, withdraw their balances as they use the Company’s products. Revenue is recognized when control of services is transferred to customers ins an amount that reflects the consideration we expect to receive in exchange for those products or services. Revenue is recognized net of any taxes levied on customers, which are subsequently remitted to government authorities. Invoiced amounts are recorded in accounts receivable and in revenue or advances from customers, depending on whether the revenue recognition criteria are met. The company's agreements with customers do not provide rights of return, and do not provide customers with the right to take possession of the software that supports the applications. Carrier billing Carrier billing is a business model in which there is a provider that makes its content available through the connections that the Company maintains with carriers (telephone operators), which provide the service to the final consumer. The provider is responsible for the content as well as the price. The Company acts as an agent in the process, receiving the amounts collected by the connections and passing on the respective amounts to the providers. Therefore, net revenue is accounted for at the fee charged to content providers for the service. The carrying billing business is characterized as an operation in which the Company has contracts with mobile operators in Brazil and providers of information content through digital platforms, on which end customers of mobile telephony operators can subscribe to the content of the operators and receive information based on their cell phones. In this operation, the Company bills mobile operators and transfers it to content providers, receiving a fee for performing this service. Revenue is recognized when content providers deliver services to end customers. Zenvia recognizes revenue at the amount of net fees to be received on these transactions.
Financial instruments	k. Financial instruments (i) Initial recognition and measurement Trade accounts receivable and debt securities issued are initially recognized on the date they were originated. All other financial assets and liabilities are initially recognized when the Company becomes party to the contractual provisions of the instrument. A financial asset (unless it is a trade receivable without a significant financing component) or financial liability is initially measured at fair value plus, for an item not measured at fair value through profit or loss (FVTPL), the transaction costs that are directly attributable to their acquisition or issuance. Accounts receivable from customers without a significant financing component are initially measured at the transaction price. (ii) Classification and subsequent measurement Upon initial recognition, a financial asset is classified as measured: at amortized cost or at fair valu e through profit or loss (FVTPL). Financial assets are not reclassified subsequent to initial recognition, unless the Company changes the business model for managing financial assets, in which case all affected financial assets are reclassified on the first day of the reporting period following the change in business model. A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as measured at FVTPL: - is held within a business model whose objective is to hold financial assets in order to receive contractual cash flows; and - its contractual terms generate, on specific dates, cash flows that are related only to the payment of principal and interest on the outstanding principal amount. The Company carries out an assessment of the purpose of the business in which a financial asset is held in the portfolio, as this better reflects the way in which the business is managed and the information is provided t o management. Financial assets held for trading or managed with performance evaluated based on fair value are measured at fair value through profit or loss. (iii) Financial assets – assessment of whether contractual cash flows are principal and interest paymen ts only For purposes of this assessment, 'principal' is defined as the fair value of the financial asset at initial recognition. ‘Interest’ is defined as consideration for the time value of money and the credit risk associated with the principal amount ou tstanding over a given period of time and for other basic borrowing risks and costs, as well as a profit margin. The Company considers the contractual terms of the instrument to assess whether the contractual cash flows are only payments of principal and interest. This includes assessing whether the financial asset contains a contractual term that could change the timing or amount of contractual cash flows such that it would not meet that condition. When making this assessment, the Company considers: contingent events that change the value or timing of cash flows; terms that may adjust the contractual rate, including variable rates; prepayment and extension of the deadline; and the terms that limit the Company's access to cash flows from specific assets. Prepayment is consistent with principal and interest payment criteria if the prepayment amount represents, for the most part, unpaid principal and interest amounts on the outstanding principal amount - which may include additional compensation reasonable for early termination of the contract. In addition, with respect to a financial asset acquired for an amount less than or greater than the face value of the contract, the permission or requirement of prepayment for an amount that re presents the face value of the contract plus contractual interest (which also may include reasonable additional compensation for early termination of the contract) accrued (but not paid) are treated as consistent with these criteria if the fair value of th e prepayment is negligible on initial recognition. Financial assets at FVTPL These assets are subsequently measured at fair value. Net income, including interest or dividend income, is recognized in profit or loss. Financial assets at amortized cost These assets are subsequently measured at amortized cost using the effective interest method. Amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized in profit or loss. Any gain or loss on derecognition is recognized in profit or loss.
Reduction to recoverable value (impairment)	l. Reduction to recoverable value (impairment) Non-derivative financial Assets (i) Financial instruments and contractual assets The Company recognizes provisions for expected credit losses on: financial assets measured at amortized cost. The Company measures the provisions for loss at an amount equal to the lifetime expected credit loss, except for the items described below, which are measured as 12-month expected credit loss: debt securities with low credit risk at the balance sheet date; and - other debt securities and bank balances for which the credit risk has not increased significantly since initial recognition. Provisions for losses on trade accounts receivable and contract assets are m easured at an amount equal to the expected credit loss over the entire life of the instrument. In determining whether the credit risk of a financial asset has increased significantly since the initial recognition and when estimating the credit loss, the C ompany considers reasonable and supportable information that is relevant and available without undue cost or effort. This includes both quantitative and qualitative information and analysis, based on the Company's historical experience and informed credit asses sment, which includes forward-looking information. The Company assumes that the credit risk of a financial asset has increased significantly if it is more than 30 days past due. The Company considers a financial asset to be in default when: the debtor is unlikely to pay its credit obligations to the Company in full, without recourse to actions such as obtaining collateral (if any); or the financial asset is more than 180 days past due. Lifetime credit loss expectations are those that result f rom all possible standard events over the expected life of a Financial Instrument. The 12-month credit loss expectations are the portion that result from possible default events within 12 months after the reporting date (or a shorter period if the expected useful life of the instrument is less than 12 months). The maximum period considered when estimating expected credit loss is the maximum contractual period over which the Company is exposed to credit risk. (ii) Measurement Expect credit loss are a probability-weighted of credit losses. Credit losses are measured as the present value of all cash shortfalls. (iii) Presentation of the provision for expected credit loss in the financial statements Provisions for losses on financial assets measur ed at amortized cost are deducted from the gross carrying amount of the assets. (iv) Write offs The gross carrying amount of a financial asset is written off when the Company does not have reasonable expectations of recovering all or part of a financial asset. The Company does not expect a significant recovery of the amount written off. However, written-off financial assets may still be subject to collection actions to comply with the Company's procedures for recovering amounts due. (v) Non-Financi al Assets At each reporting date, the Company reviews the book values ​​of its non-financial assets (customer portfolio, platform, property, plant and equipment) to determine whether there is any indication of impairme nt. If such an indication exists, the n the asset 's recoverable amount is estimated. For impairment tests, assets are grouped into the smallest asset group that generates cash inflows from continuing use that are largely independent of cash inflows from other assets. Goodwill is allocated to cash-generating units (CGU) for impairment testing purposes. The allocation is made to the cash-generating units or groups of cash-generating units that are expected to benefit from the business combination from which the goodwill originated. Units or groups of units are identified at the lowest level at which goodwill is monitored for internal management purposes, not considered as report segments. Goodwill is tested for impairment annually as at December 31 and when circumstances indicate that the carrying value may be impaired. Impairment is determined for goodwill by assessing the recoverable amount of the segment to which the goodwill relates. Whe n the recoverable amount is less than the carrying amount, an impairment loss is recognized. Impairment losses relating to goodwill cannot be reversed in future periods.
Property, plant and equipment	m. Property, plant and equipment (i) Recognition and measurement Property, plant, and equipment items are measured at historical acquisition or construction cost, less accumulated depreciation and accumulated impairment losses, if applicable. Cost includes expenses that are directly attributable to the acquisition of an asset. Gains and l osses on the sale of an item of property, plant and equipment are determined by comparing the proceeds from the sale with the book value of the property, plant, and equipment, and are recognized net within other income in the statement of profit or loss. (ii) Subseque nt costs The replacement cost of a component of property, plant and equipment is recognized in the carrying amount of the item if it is probable that the economic benefits embodied within the component will flow to the Company and its cost can be measured reliably. The carrying amount of the component that has been replaced by another is written off. The day-to-day maintenance costs of property, plant and equipment are recognized as expenses in the statements of profit or loss as incurred . (iii) Depreciation Depre ciation is recognized in profit or loss based on the straight-line method based on the estimated useful life of each component, since this method is the one that most closely reflects the pattern of consumption of future economic benefits embodied in the a sset. Deprecia tion methods, useful lives and residual values ​​are reviewed at each reporting date and adjusted, if appropriate.
Intangible asset	n. Intangible asset (i) Initial recognition Intangible assets that are acquired by the Company and that have defined useful lives are meas ured at cost, less accumulated amortization, and any accumulated impairment losses. (ii) Subsequent expenses Subsequent expenditures are capitalized only when they increase the future economic benefits embodied in the specific asset to wh ich they relate. All other expenses are recognized in profit or loss as incurred. (iii) Amortization Amortization is calculated to lower the cost of intangible assets, less their estimated residual values, using the straight-line method over their estimated useful lives and is recognized in profit or loss. Goodwill is not amortized. (iv) Intangible assets - Research and development expenses Expenses with research activities are recognized as an expense in the period in which they are incurred. Interna lly generated intangible assets resulting from development expenditures (or a development phase of an internal project) are recognized if, and only if, all of the following conditions are demonstrated: • The technical feasibility of completing the intangible asset so that it is available for use or sale. • The intention to complete the intangible asset and use or sell it. • The ability to use or sell the intangible asset. • How the intangible asset will generate probable future economic benefits. • The availability of adequate technical, financial, and other resources to complete the development of the intangible asset and to use or sell it. • The ability to reliably measure the expenses attributable to the intangible asset during its development. The initially recogni zed amount of internally generated intangible assets corresponds to the sum of expenses incurred since when the intangible asset started meeting the recognition criteria. Appropriation is based on employee time records allocated to these developments at t he cost of these employees. When no internally generated intangible asset can be recognized, development costs are recognized in profit or loss for the period when incurred. Subsequent to initial recognition, internally generated intangible assets are re corded at cost, less accumulated amortization, and impairment losses. (v) Goodwill Goodwill resulting from a business combination is stated at cost on the date of the business combination, net of accumulated impairment losses, if any.
Income tax and social contribution	o. Income tax and social contribution For the entities domiciled in Brazil, the current and deferred income and social contribution taxes are calculated based on the rates of 15% plus a surcharge of 10% on taxable income in excess of Brazilian Reais (BRL) 240% per annum for income tax and 9% on taxable income for so cial contribution on net income and consider the offsetting of tax loss carryforward and negative basis of social contribution limited to 30% of the taxable income. Income taxes applicable to the subsidiary located in the United States are calculated at a rate of 21% of taxable income for the year. For the subsidiaries in Mexico and Argen tina, the current income taxes are calculated based on the rate of 30%. Current and deferred taxes are recognized in profit or loss unless they are related to the business combination, or items directly recognized in shareholders' equity. (i) Current tax Current tax is the estimated tax payable or receivable on taxable income or loss for the year and any adjustment to taxes payable with respect to prior years. It is measur ed based on the tax rates enacted or substantively enacted at the balance sheet date. Among the existing tax incentives in Brazil , the Company uses the benefit arising from the “Lei do Bem” (Law No. 11,196/05), aimed at companies that carry out resea rch and development (R&D) of technological innovation. This benefit provides tax savings by reducing the income tax and social contribution tax base from 60% to 80% of R&D expenditures. (ii) Deferred tax Deferred tax is recognized in respect of temporary differences between the carrying amounts of assets and liabilities for accounting purposes and the corresponding amounts used for taxation purposes. A deferred income tax and social contribution asset is recognized in relation to unused tax loss es, tax credits and deductible temporary differences, to the extent that it is probable that future taxable profits will be available against which they will be used. Deferred income tax and social contribution assets are reviewed at each balance sheet dat e and are reduced to the extent that their realization is no longer probable. Deferred tax is measured based on the rates that are expected to apply to temporary differences when they are reversed, based on the rates that were enacted or substantively enacted up reporting date. The measurement of deferred tax reflects the tax consequences that would follow the manner in which the Company expects to recover or settle the carrying amount of its assets and liabilities. Deferred i ncome tax and social contribution assets are reviewed at the reporting dates and will be reduced to the extent that their realization is no longer probable.
Provisions	p. Provisions A provision is recognized in the statement of financial position when the Company has a legal or constru ctive obligation as a result of a past event, and it is probable that an outflow of economic benefits will be required to settle the obligation. Provisions are recorded based on the best estimates of the risk involved. The Company sets up provisions to co ver future disbursements that may arise from tax, labor and civil proceedings in progress. Provisions are set up based on the analysis of legal proceedings in progress and on the prospect of an unfavorable outcome, implying a future disbursement. Contingent assets are not recognized until the actions are finalized with a definitive favorable position for the Company and when it is virtually certain that it will realize the asset. The taxes whose enforceability is being questioned in the judicial sphere are r ecorded taking into account the concept of “legal obligation”. Judicial deposits made in guarantee of ongoing lawsuits are recorded under “Judicial Deposits” (see note 16 Provisions are reassessed at the dates of the financial statements and adjusted to reflect the best current estimate. If it is no longer probable that an outflow of resources will be required to settle the obligation, the provision is reversed.
Share capital	q. Share capital The incremental costs directly attributable to the issuance of new shares o r options are shown in equity as a deduction from the amount raised, net of taxes. The capital is composed of 41,324,506 common shares. Capital increases are allowed by resolution of the Board of Directors independently of amendment to its bylaws up to the limit of 1,000,000,000 new nominative common shares with no nominal value.
Financial income and financial expenses	r. Financial income and financial expenses Financial income includes interest income, income from investments, exchange gains on the variation of assets and liabilities indexed in foreign currency. Interest income is recognized in income using the effective interest method. Financial expenses include interest expenses on loans and exchange losses on the variation of assets and liabilities indexed in foreign currency. Borrowing costs that are not directly attributable to the acquisition, construction or production of a qualifying asset are accounted for in profit or loss using the effective interest method.
Employee benefits	s. Employee benefits Profit sharing and bonuses – Employees' profit sharing and variable compensation for executives are linked to the achievement of operational and financial goals. The Company recognizes liabilities and related expenses, which are allocated to costs of services and administrative expenses, when the goals are probable to be met.

The quoted market price used for financial assets held by the Group is the current bid price. These instruments are included in level 1. • Level 2: The fair value of financial instruments that are not traded in an active market (for example, over-the-counter derivatives) is determined using valuation techniques that maximize the use of observable market data and rely as little as possible on entity-specific estimates. If all significant inputs required to fair value an instrument are observable, the instrument is included in level 2. • Level 3: Inputs for the asset or liability that are not based on observable market data (unobservable inputs).

Description of valuation techniques used in business combination	The MPEEM methodology (Multi Period Excess Earnings Method) is mostly used to measure the value of primary assets or most important assets of a company. According to that method, in determining fair values, the cash flows attributable to all other assets are subtracted through a contributory asset charge (CAC). The MPEEM method assumes that the fair value of an intangible asset is the same as the present value of the cash flows attributable to that asset, less the contribution of other assets, both tangible and intangible ones.

Communication Platform
Disclosure of disaggregation of revenue from contracts with customers [line items]
Nature and timing of satisfaction of performance obligations, including significant payment terms	The Company's revenue derives mainly from fees based on the use of services available on its communication platform. Use of these services is measured by individual volume and revenues based on these volumes are recognized over the period of use. The Company provides services to customers with prepaid contracts and term contracts for a fixed or indefinite period. Small customers and customers who pay by credit card are billed in advance, while large customers are billed monthly on the postpaid model. Collections are made within thirty days of billing. Customers who pay in the prepaid model, withdraw their balances as they use the Company’s products.
Revenue recognition policy	Revenue is recognized when control of services is transferred to customers ins an amount that reflects the consideration we expect to receive in exchange for those products or services. Revenue is recognized net of any taxes levied on customers, which are subsequently remitted to government authorities. Invoiced amounts are recorded in accounts receivable and in revenue or advances from customers, depending on whether the revenue recognition criteria are met. The company's agreements with customers do not provide rights of return, and do not provide customers with the right to take possession of the software that supports the applications.
Carrier billing
Disclosure of disaggregation of revenue from contracts with customers [line items]
Nature and timing of satisfaction of performance obligations, including significant payment terms	Carrier billing is a business model in which there is a provider that makes its content available through the connections that the Company maintains with carriers (telephone operators), which provide the service to the final consumer. The provider is responsible for the content as well as the price. The Company acts as an agent in the process, receiving the amounts collected by the connections and passing on the respective amounts to the providers. Therefore, net revenue is accounted for at the fee charged to content providers for the service.
Revenue recognition policy	The carrying billing business is characterized as an operation in which the Company has contracts with mobile operators in Brazil and providers of information content through digital platforms, on which end customers of mobile telephony operators can subscribe to the content of the operators and receive information based on their cell phones. In this operation, the Company bills mobile operators and transfers it to content providers, receiving a fee for performing this service. Revenue is recognized when content providers deliver services to end customers. Zenvia recognizes revenue at the amount of net fees to be received on these transactions.

[1]	Revenue recognition in the industry of mobile, fixed and internet communication platform services involves complex billing systems, with processing of large volumes of data and with price variations from the different plans. Additionally, in this context, the Company's revenues are recognized monthly, with the invoiced portion and the unbilled portion, arising from services provided between the billing date and the end of each month, being identified, processed and recognized within the month in which the service has been provided. Thus, "revenues to be billed" - recorded in the accounts each month, are calculated based on the proportion of services performed up to the date of presentation of the financial information.
