Notes to the unaudited interim condensed consolidated financial statements

For the three-month period ended March 31, 2022

Expressed in thousands of Brazilian reais, unless otherwise stated

1 Corporate information

Arco Platform Limited (“Arco”) is a holding company incorporated under the laws of the Cayman Islands on April 12, 2018 and whose shares are publicly traded on the National Association of Securities Dealers Automated Quotations Payments exchange (NASDAQ) under the ticker symbol “ARCE”. Arco and its subsidiaries are collectively referred to as the Company. Arco became the parent company of Arco Educação S.A. ("Arco Brazil") through the completion of the corporate reorganization and initial public offering of the Company in 2018. Arco Brazil is the holding company of the operating subsidiaries, including Companhia Brasileira de Educação e Sistemas de Ensino S.A. (“CBE”), which provides educational content from basic to secondary education (“K-12 curriculum”). The Company’s principal administrative office is located at 2840 Rua Augusta, 9th Floor, Consolação, São Paulo, Brazil.

These unaudited interim condensed consolidated financial statements were authorized for issue by the Board of Directors on May 20, 2022.

1.2 Significant events during the period

(a) Financial transactions

Loan liquidation

On January 3, 2022, the Company paid in full a loan through one of its subsidiaries Arco Educação, in the amount of R$ 201,883.

Acquisition of PGS and Mentes do Amanhã

On February 3, 2022, Arco concluded the acquisition of the following solutions from Pearson Education do Brasil Ltda.

(i) PGS: a K-12 bilingual courseware and teaching methodology, previously known as Pearson Global School; and (ii) Mentes do Amanhã (“Mentes”): a K12 supplemental solution focused on 21st century skills (social-emotional learning, financial literacy and technology).

The purchase consideration consists of: (i) R$ 5,507 paid in February 2022; and 

(ii) R$ 8,701 which will be settled until May 2022.

This transaction broadens Arco’s supplemental market presence by adding high-quality solutions with pricing complementary to its portfolio. Arco believes in the large potential for English as a Second Language and in the favorable market trends for 21st century skills. An even stronger portfolio better positions Arco to capture this demand outside Arco’s school base.

F-6

Shares repurchase

During the three-month period ended March 31, 2022, the Company purchased an aggregate amount of 338,718 Class A common shares for a total of approximately US$ 6.6 million. This repurchase was made in accordance with the Repurchase Program mentioned in Note 16.

(b) Information related to Covid-19 pandemic

In January 2021, the COVID vaccine began to be applied in Brazil. Vaccination started with the priority groups: health workers, the elderly, the disabled and indigenous villagers. Currently the vaccine is available to all the adult population in Brazil and children above the age of 5 years old, and the vaccination campaign has maintained a rapid pace since its beginning.

After the holiday celebrations at the end of 2021, there was an increase in the number of COVID-19 cases in Brazil. During January 2022, state and municipal governments took restrictive measures to contain a possible new wave of the virus. These measures have been relaxed as the number of cases decreased compared to the beginning of the year.

Currently, the Country presents an optimistic scenario and is believed to be closer to the end of the pandemic, since on average 85,9% of the Brazilian population are vaccinated with at least the first dose, and about 77,2% of the population are fully vaccinated according to information from Brazilian health authorities.

The initial restrictive measures taken by Brazilian states and local authorities directly impacted the education industry by indefinitely postponing on-site school activities at the beginning of the pandemic. However, in 2022 school activities returned to the presential modality. The mandatory use of masks is occurring in stages, with restrictions over some activities being gradually released.

Notwithstanding the above, despite the gradual release of the restrictions by the authorities, most of the Company’s workforce is working on site applying a hybrid model. The Company continues putting in place protocols to safeguard the health and safety of the Company’s employees, customers, and suppliers. The alternative working arrangements have not adversely affected financial reporting systems, internal control over financial reporting or disclosure controls and procedures.

As of March 31, 2022, the Company did not recognize any additional expenses related to COVID-19, mainly due to flexibility of restricted measures and the high percentage of the target population vaccinated in Brazil.

Notwithstanding the above, given the uncertainty around the extent and timing of the future spread of COVID-19, the imposition of additional protective measures, or the relaxation of existing protective measures, it is not possible to accurately predict COVID-19's general impact on the education industry in Brazil or to reasonably estimate its impact on Arco's results of operations, cash flows or financial condition, including, but not limited to:

F-7

• A decrease in the number of students, which may impact the expected amount of revenue.

• An increase in bad debts due to the current economic scenario.

• An adverse change in the fair value of financial instruments recognized on the Company’s books.

• The need for renegotiation of loans and lease agreements to ensure the continued strength of the Company’s financial position.

The Company does not expect to incur additional expenses from COVID-19, but Management will continue to monitor and assess the impact COVID-19 may have on the Company’s business operations, financial performance, financial position, and cash flows.

2 Significant accounting policies

2.1 Basis for preparation of the consolidated financial statements

These unaudited interim condensed consolidated financial statements have been prepared in accordance with IAS 34 Interim Financial Reporting ("IAS 34") as issued by the International Accounting Standards Board (“IASB”). Accordingly, certain disclosures included in the Company’s annual consolidated financial statements prepared in accordance with International Financial Reporting Standards (“IFRSs”) as issued by the IASB have been condensed or omitted. These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s annual consolidated financial statements for the year ended December 31, 2021, which include information necessary or useful to understanding the Company’s business and financial statement presentation. In particular, the Company’s significant accounting policies were presented in Note 2 Significant accounting policies to the consolidated financial statements for the year ended December 31, 2021.

The accounting policies applied in the preparation of these unaudited interim condensed consolidated financial statements are consistent with those applied and disclosed in the Company’s consolidated financial statements for the year ended December 31, 2021.

In preparing these unaudited interim condensed consolidated financial statements, management has made judgements, estimates and assumptions that affect the application of accounting policies and the reported amounts of assets and liabilities, revenue, and expenses. Actual results may differ from these estimates. The critical judgements made by management in applying the Company’s accounting policies and the key sources of estimation uncertainty were the same as those applied and disclosed in Note 3 Significant accounting judgments, estimates and assumptions to the Company’s consolidated financial statements for the year ended December 31, 2021.

The unaudited interim condensed consolidated financial statements are presented in Brazilian reais (“BRL” or “R$”), which is the Company’s functional and presentation currency. All amounts are rounded to the nearest thousands, except when otherwise indicated.

The Company intends to adopt these new and amended standards and interpretations, if applicable, when they become effective. The Company is assessing the impact that changes in the standards will have in current practice, but does not expect a significant or any impact to occur on the Company's financial statements:

Advances from customers

The Company receives advance from customers mainly at the beginning of the year when parents purchase educational content for the current school year. The educational content is delivered in up to four stages, and as the material is delivered, revenue is recognized, and the advance from customers is offset.

As of March 31, 2022, the Company has R$170,461 (R$35,291 in December 2021) of advances from customers recorded in liabilities for which the material was not delivered in the current period.

The increase of the balance is due the growth on the business to consumer (B2C) sales model which represents 28.5% of revenue as of March 31, 2022 (17.8% as of March 31, 2021).

		1,949,901		1,949,901

Impairment test for goodwill

The Company performs its annual impairment test in the last quarter of the previous year and whenever circumstances indicate that the carrying value may be impaired. The Company’s impairment test for goodwill is based on value-in-use calculations. The key assumptions used to determine the recoverable amount for the different cash generating units were disclosed in the annual consolidated financial statements for the year ended December 31, 2021.

There were no indicators of impairment for the three-month periods ended March 31, 2022.

(b) Other intangible assets

For the three-month period ended March 31, 2022 there were no indicators that the Company’s intangible assets with definite lives might be impaired.

(a) This amount is related to issuance of debentures in August 2021 to pay the amount due on the COC and Dom Bosco acquisition and will be settled in a single installment on August 25, 2023. The debentures bear interest of 100% CDI + 1.7% per annum, which will accrue and will also be payable on August 25, 2023. The debentures are guaranteed by Arco Educação S.A.

F-19

(b) Loan acquired by Me Salva!, the Company’s subsidiary, for working capital. The amount will be settled in 3 installments until October 2023 and bear interest at the rate of 3.7% per annum.

(c) Loan acquired by Eduqo, the Company’s subsidiary, for working capital. The amount is being paid monthly until October 2023 and bear interest at the rate of 3.8% per annum.

(d) On November 11, 2021, the subsidiary Geekie entered into a loan agreement in the amount of US$ 11,020 thousand, equivalent to R$ 60,000, with an interest rate of 2.452% per annum. Since the operation was contracted in U.S. dollars, the Company holds swap derivatives to protect its exposure to foreign currency risk, which changes the effective interest rate for this loan to 100% CDI + 1.7% per annum. The loan payments are due quarterly in 12 installments, until October 28, 2024. The decrease in the current balance is mainly related to: (i) payment of R$ 5,455 related to first installment in February 2022; and (ii) exchange variation of R$ 8,680 recognized as financial income in statement of income.

(e) On November 30, 2021, the Company issued convertible senior notes in the amount of US$ 150,000 with a value per share of $1.00, equivalent to R$ 825,285. These notes mature in 7 years, on November 15, 2028, and bear interest at 8% per year fixed in Brazilian reais. While the interests are payable quarterly, the principal amount will be paid in a single installment at the mature date, both in cash in United States dollars equivalents to the amount in Brazilian reais at the payment date.

Each note can be converted at any time during the term of the contract, at the option of the holders, into Arco’s Class A common shares at the agreed conversion rate, which is equivalent to an initial price of US$ 29 per share. Dragoneer and General Atlantic will beneficially own approximately 5.6% and 2.8%, respectively, of the total shares of Arco (on an as-converted basis for the convertible senior notes). See Note 13 for further information.

The holders also have the right to require the Company to repurchase for cash, on any date on or after November 15, 2026, all or portion of the holders’ notes, at a repurchase price that is equal to 100% of the principal amount of the notes to be repurchased, plus accrued and unpaid interests.

The Company determined that the convertible senior notes have an embedded put option to repurchase the convertible notes for cash. It is an embedded derivative that is not closely related to the contract host debt instrument, because the risks inherent in the derivative (equity risk) and the host are dissimilar. Therefore, the conversion option will be treated separately and classified as a derivative liability, see Note 13 for further information.

The host foreign currency debt will be measured subsequently at amortized cost, using the effective interest rate of 3.61% per annum, and thus is subject to foreign exchange changes.

The decrease in current balance is mainly due to exchange variation of R$ 98,654 recognized as financial income in statement of income. The remain variation is related to interest provisioned in the period.

All financing arranged by the Company is not subject to any financial covenants as of March 31, 2022.

During the three-month period ended March 31, 2022 the Company recognized R$ 6,617 of interest and the accounts payable increased by R$ 1,103.

(g) The liability is composed of the present value of the balance payable for the remaining 40% interest in Me Salva!, plus the retained amount defined in the contract. The balance is recognized at present value, using a discount rate of 12.4% (13.7% in 2021). The payment of the retained portion is in the amount of R$ 1,124 and will be made in 4 equal annual installments, in June of each year until 2026. The payment of the second stage will be made in 2025 and the acquisition price of 40% is calculated based on the estimated 2024 revenue multiplied by 3, less net debt. During the three-month period ended March 31, 2022 the Company recognized an interest expense of R$ 778 and the accounts payable increased by R$ 742.

The payment of the outstanding installments in the amount of R$ 17,097 and the earn out of R$2,896 will be made in 2 annual installments, in July of 2022 and 2023. The price adjustment of R$ 882 will be paid in a single installment in July 2022. The earn-out is calculated based on the estimated 2022 and 2023 revenue, plus cash generation. During the three-month period ended March 31, 2022 the Company recognized an interest expense of R$ 1,849.

(i) The liability is composed of the present value of the balance payable for the outstanding installments for settlement of the 100% participation acquired from Edupass, plus the earn out amount defined in the contract.

(a) Variable remuneration (bonuses)

The Company recorded bonuses related to variable remuneration of employees and management in cost of sales, selling and administrative expenses in the amount of R$13,238 during the three-month period ended March 31, 2022 (2021: R$ 7,337).

(b) Share-based compensation plan

Geekie Plan

The beneficiaries exercised the options on March 31, 2022, which is under review for its payment until June 2022.

The fair value of the plan is calculated using the same valuation method as the accounts payable to selling shareholders for the acquisition of the remaining interest.

Although the valuation used in both calculations is the same, Arco recorded accounts payable to selling shareholders, and Geekie recorded stock options for employees who remained in the company after the acquisition without the possibility of liquidation in equity as labor and social obligations.

Restricted stock units

In 2019 the Company implemented a new share-based payment program called restricted stock units (“RSU”) of the holding company Arco Platfom Limited for employees of the Company's subsidiaries and members of the Board of Directors, which will be available for sale by the beneficiaries annually, on their anniversary dates, except for the members of the Board, whose shares are restricted for sale for one year after vesting.

The participant's right to effectively receive ownership of the restricted shares will be conditioned to the participant's continuance and performance as an employee, director or director of any company in the business group from the grant date until vesting. If a participant leaves the group or does not achieve the proposed performance goal, the participant will be entitled to receive his or her vested shares and a pro rata amount of the granted and unvested shares, by reference to the vesting period in which the termination occurred and based on the number of days the participant was employed by us. The total amount will be calculated based on the proposed goal multiplied by a rate between 80% and 120%. After the vesting period, the restricted shares have the same rights and privileges as any shareholder.

The following table reflects the movements of outstanding shares from the grant date until March 31, 2022:

	Number of restricted stock units
Outstanding at December 31, 2021		142,184
Granted (a)		2,404
Restricted stocks units transferred		(40,131	)
Estimated forfeited		3,682
Outstanding at March 31, 2022		108,139

(a) These shares granted are adjusted accordingly to a performance program, which can increase or reduce the number of shares that will be transferred after the vesting period.

The total compensation expense for the three-month period ended March 31, 2022, including taxes and social charges, was R$10,321, (R$3,590 of principal and R$6,731 of taxes and contributions) net of estimated forfeitures. These awards are classified as equity settled.

(a) The grant date is the date on which the entity and the counterparty (including employee) entered into a share-based payment agreement, that is, when the entity and the counterparty have a shared understanding of the terms and conditions of the agreement.

(b) Includes the number of Restricted Shares pro rata in relation to the vesting period not yet fulfilled, based on the number of days the participant worked for the Company during such vesting period until the closing of these financial statements, whose Restricted Shares will be transferred to the participant only after the vesting period has been completed or in the event of contractual termination.

Matching program

On February 26, 2021, the Company’s Restricted Shares Plan Advisory Committee approved the Company’s first Matching Program, pursuant to which the Company will match the number of Class A shares (at no additional cost to the participant) that were acquired by the participant at fair market value (“investment shares”), using the amounts received by the participant as a short term incentive and designated by the Company’s board of directors to be used as an investment in investment shares, provided certain vesting conditions are satisfied.

Under the matching shares program, participants are required to (i) be employed or providing services to the Company through each vesting date, as set forth in the applicable award agreement and (ii) hold the investment shares through each vesting date. The vesting period may not exceed five years. In addition, upon each vesting date, a portion of the investment shares will become free of restrictions and the participant will be allowed to freely sell such shares.

All Class A shares, including the investment shares acquired by the participants of the Matching Program, will be available for sale by the beneficiaries annually, over four years, on March 31 of each year.

16 Equity

a. Share capital

As of March 31, 2022, and December 2021, Arco’s share capital is represented by 56,851,399 common shares of par value of US$ 0.00005 each, comprised of 27,400,848 Class B common shares and 29,450,551 Class A common shares.

F-26

The Class B common shares are entitled to 10 votes per share and the Class A common shares, which are publicly traded, are entitled to one vote per share. The Class B common shares are convertible into an equivalent number of Class A common shares and generally convert into Class A common shares upon transfer subject to limited exceptions.

The dual class structure will exist as long as the total number of issued and outstanding Class B common shares is at least 10% of the total number of shares outstanding.

b. Treasury shares

Repurchase program

On January 6, 2021, the Company’s Board of Directors approved a share repurchase program, or the Repurchase Program, to comply with management long-term incentive plan obligations. Pursuant to the Repurchase Program, the Company may repurchase up to 500,000 of our outstanding Class A common shares in the open market, based on prevailing market prices, or in privately negotiated transactions, over a period beginning on January 6, 2021, continuing until the earlier of the completion of the repurchase or January 6, 2023, depending upon market conditions.

On March 31, 2021, the Company approved to increase the share repurchase limit of its existing share repurchase program established on January 6, 2021. Pursuant to the increased repurchase limit, Arco may repurchase up to 2,500,000 million of its outstanding Class A common shares in the open market, based on prevailing market prices, or in privately negotiated transactions, over a period beginning on March 31, 2021, continuing until the earlier of the completion of the repurchase or January 6, 2023, depending upon market conditions.

The following table reflects the movements of treasury shares repurchased until March 31, 2022:

	Number of restricted stock units
As of December 31, 2021		605,316
Repurchase		338,718
Transferred – RSU’s program		(83,879	)
As of March 31, 2022		860,155

As of March 31, 2022, the Company has a total of 860,155 of treasury Class A common shares under the Repurchase Program with an average price of US$ 21.3.

17 Earnings per share (EPS)

Basic

Basic EPS is calculated by dividing income attributable to the equity holders of the parent by the weighted average number of Class A and Class B common shares outstanding during the period.

F-27

Diluted

Diluted EPS is calculated by dividing profit attributable to the equity holders of the parent by the weighted average number of Class A and Class B common shares outstanding during the period plus the weighted average number of common shares that would be issued on conversion of all potential common shares with dilutive effects.

The following table reflects the income attributable to equity holders of the parent and the share data used in the basic and diluted EPS computations:

	Three-month period ended						Three-month period ended
	March 31, 2022 (unaudited)						March 31, 2021 (unaudited)
	Class A		Class B		Total		Class A		Class B		Total
Income attributable to equity holders of the parent		52,517		50,142		102,659		6,174		5,637		11,811
Weighted average number of common shares outstanding (thousand)		28,699		27,401		56,100		30,010		27,401		57,411
Effects of dilution from:
Share-based compensation plan (thousands)		108		-				220		-
Basic loss per share - R$		1.83		1.83				0.21		0.21
Diluted loss per share - R$		1.82		1.83				0.20		0.21

Diluted income per share is calculated by the weighted average number of outstanding shares, in order to assume the conversion of all potential dilutive shares. Diluted result per share is calculated considering the instruments that may have a potential dilutive effect in the future, such as share-based payment instruments, using the treasury shares method when the effect is dilutive.

(a) The Company measures at fair value through profit or loss the contingent consideration arising from business combinations in accordance with IFRS 3.

The maximum exposure to credit risk at the end of the reporting period is the carrying amount of each class of financial assets mentioned above.

Financial instruments at fair value through profit or loss

Derivative assets and liabilities

The Company maintains put options from investments and swap derivatives to protect its exposure to foreign currency risk, specifically for loans contracts. These derivatives are measured at fair value and are presented as financial assets when the fair value results in a gain, and as financial liabilities when the fair value results in a loss. Any gains or losses from these derivatives are recognized directly in the income statement.

As of March 31, 2022 and December 31, 2021, none of the Company’s derivatives has been designated as hedges for accounting purposes.

Amounts recognized in profit or loss

Changes in fair values of financial instruments at fair value through profit or loss are recorded in finance income (expenses) in profit or loss. For the three-month period ended March 31, 2022, the Company recognized a net financial income of R$ 11,653.

F-37

Recognized fair value measurements

(i) Fair value hierarchy

The table below explains the judgements and estimates made in determining the fair values of the financial instruments that are recognized and measured at fair value through profit or loss in the consolidated financial statements. To provide an indication about the reliability of the inputs used in determining fair value, the Company has classified its financial instruments into the three levels.

Assets and liabilities measured and recognized at fair value as follows:

	Hierarchy	March 31, 2022		December 31, 2021
			(unaudited)
Financial assets
Derivative financial instruments	Level 2		-		861
Investments at fair value	Level 1		9,814		9,803
Financial liabilities
Derivative financial liabilities	Level 2		10,281		-
Derivative financial liabilities	Level 3		200,479		223,561
Accounts payable to selling shareholders	Level 3		887,929		867,264

As of March 31, 2022, and December 31, 2021, the Company assessed the fair values of its financial instruments and concluded that carrying amounts and fair values approximate. The estimated realizable values of financial assets and liabilities were determined based on available market information and appropriate valuation methodologies.

The Company’s policy is to recognize transfers into and transfers out of fair value hierarchy levels as at the end of the reporting period.

There were no transfers between levels for recurring fair value measurements during the financial statement period.

(ii) Valuation techniques used to determine fair values

Specific valuation techniques used to value financial instruments include:

● the use of quoted market prices or dealer quotes for similar instruments;

● the fair value of derivatives is calculated with Black & Scholes; and

● the fair value of the remaining financial instruments is determined using discounted cash flow analysis.

All the resulting fair value estimates are included in levels 1 and 2 except for contingent consideration and certain derivative contracts, where the fair values have been determined based on present values and the discount rates used were adjusted for counterparty or own credit risk.

F-38

If the inputs used to measure the fair value of an asset or a liability fall into different levels of the fair value hierarchy, then the fair value measurement is categorized in its entirety in the same level of the fair value hierarchy as the lowest level input that is significant to the entire measurement.

(iii) Fair value measurements using significant unobservable inputs (level 3)

The following table presents the changes in level 3 items for the three-month periods ended March 31, 2022 and 2021.

Recurring fair value measurements	Financial instruments liabilities			Accounts payable to selling shareholders
As of December 31, 2020		-			(861,385	)
Acquisitions		-			(23,520	)
Payment		-			22,646
Changes in accounts payable to selling shareholders		-			2,188
Interest expense		-			(23,075	)
Other		-			4,000
As of March 31, 2021 (unaudited)		-			(879,146	)
As of December 31, 2021		(223,561	)		(867,264	)
Changes in accounts payable to selling shareholders		-			(7,028	)
Changes in derivative instruments fair value		23,082			-
Interest expense		-			(13,637	)
As of March 31, 2022 (unaudited)		(200,479	)		(887,929	)

(iv) Transfers between levels 2 and 3

During the three-month periods ended March 31, 2022 and 2021, the Company did not transfer any financial instruments from level 2 into level 3.

(v) Valuation processes

The finance department of the Company performs and reviews the valuations of items required for financial reporting purposes, including level 3 fair values. Discussions of valuation processes and results conform with the Company’s yearly reporting periods. Also, the Company uses specialists to measure fair value of certain financial assets independently.

The main level 3 inputs used by the Company are derived and evaluated as follows:

● Discount rates for financial assets and financial liabilities are determined using a capital asset pricing model to calculate a pre-tax rate that reflects current market assessments of the time value of money and the risk specific to the asset.

● Risk adjustments specific to the counterparties (including assumptions about credit default rates) are derived from observable market data of credit risk grading.

● Earnings growth factors for unlisted equity securities are estimated based on market information for similar types of companies.

● Contingent consideration – expected cash outflows are estimated based on the terms of the business combinations and the entity’s knowledge of the business as well as how the current economic environment is likely to impact it.

Civil (a)		7,083		7,032
Labor (b)		3,253		1,972
Total		10,336		9,004

(a) The civil proceedings relate mainly to customer claims, including those related to the early termination of certain agreements, among others;

(b) The labor proceedings to which the Company is a party were filed by former employees or suppliers and third-party service providers’ employees seeking joint liability for the acts of the Company’s suppliers and service providers.

On September 19, 2019, Mr. Ulisses Borges Cardinot, the non-controlling shareholder in our subsidiary, International School, filed a request for arbitration with the Center for Arbitration and Mediation of the Chamber of Commerce Brazil-Canada in Brazil against Arco Platform Limited, Companhia Brasileira de Educação e Sistemas de Ensino S.A. and Arco Educação S.A. This request for arbitration purporting to assert the non-controlling shareholder’s rights related to both the form of payment (shares) and the calculation of the purchase price under the Investment Agreement is still ongoing.

On November 29, 2021, the arbitration panel issued a partial award on the merits of the arbitration. The decision is under the ongoing review of financial and legal advisors of the Company and its amount calculated will be further discussed in the award liquidation phase of the arbitration proceeding. However, the arbitration panel decided that (i) Arco Platform Ltd. and Arco Educação S.A. are not subject to the terms of the Investment Agreement, therefore, shall not be part of the arbitration proceeding; (ii) Mr. Cardinot will not be entitled to receive shares of Arco Platform; and (iii) the amount due by Companhia Brasileira de Educação e Sistemas de Ensino S.A. shall be calculated based on the 10 times realized EBITDA for the school years of 2019 (first installment) and 2020 (second installment), both net of net debt, as determined in the investment agreement, consistent with the calculation methodology to estimate the provisioned amount in our balance sheet as reported.

F-40

In light of the arbitration proceeding and based on IAS 37, the Company understands that the circumstances, risks and uncertainties of the arbitration must be taken into consideration in order to reach the best estimate of the liability. Contingencies should be reevaluated at each balance sheet date and adjusted to reflect the best current estimate.

Based on the arbitration panel decision mentioned above, the Company has recorded the provision of the amount considered the amount due for the purchase price under the Investment Agreement payable to the non-controlling shareholder. The liability is calculated based on the realized EBITDA for the school years of 2019 (first installment) and 2020 (second installment), both, net of net debt, as determined in the agreement. The school year is defined as the twelve-month period starting in October of the previous year to September of the mentioned current year. The first and second installments will be paid in the due course of the arbitration. During the three-month period ended March 31, 2022, the Company recognized R$ 8,823 of interest expense based on the Sistema Especial de Liquidação e Custódia - SELIC rate. The use of the SELIC rate and the amount of interest to be paid are assumptions by the Company. These assumptions may differ from the actual rate of interest, the amount of interest that will be paid, as well as which party will be responsible for its payment, since they will be determined by the arbitration panel. 

25 Transactions not involving cash

The Company carried out the non-cash activities in the three-month period ended March 31, 2022, which are not reflected in the statement of cash flows, mainly related to the effects of lease contracts signed in the period and acquisition of trademarks Mentes do Amanhã and PGS as described in Notes 10 and 11, respectively.
