(d) 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.

F-9

Since June 30, 2021, the pace of vaccination in Brazil has accelerated and it is estimated that most of the Country’s population over 18 years of age will be immunized by December 2021.

Currently, the country presents an optimistic scenario and is believed to be closer to the end of the pandemic, since on average 90% of the Brazilian population over 18 years of age is vaccinated with at least the first dose, and about 40% of this target audience is fully vaccinated according to information from Brazilian health authorities.

The initial restriction measures taken by Brazilian states and local authorities directly impacted the education industry by indefinitely postponing on-site school activities. Nonetheless, education was included in the essential activities list by some states in 2021, allowing private schools to conduct classes on a hybrid model, with on-site and remote classes. The resumption of Brazilian economic activity is occurring in stages, with restrictions over some activities being gradually lifted, including restrictions for the education sector, in accordance with specific health and safety protocols. In person classes are returning but is occurring differently in each Brazilian state, according to their particular circumstances.

Notwithstanding the above, the Company did not suspend its activities and, despite the gradual lifting of the restrictions by the authorities, most of its workforce continues to work remotely from home, except for part of the Company’s administrative and distribution centers’ teams that are working on-site, in accordance with health and safety protocols and social distancing guidelines. The Company has made additional investments in IT and network infrastructure; incurred additional expenses for cleaning and disinfecting the installations; purchased alcohol and masks; funded COVID-19 tests and H1N1 flu vaccination campaigns with the objective of taking care of its employees, reducing the demand for care in health units and facilitating the diagnosis of COVID-19. The Company also delivered chairs, computers, and work kits to its employees. Additionally, to support partner schools, since the beginning of the pandemic, the Company has made available an integrated platform with daily live classes to all students, webinars, broadcast, and remote support to maintain student learning, while complying with social distancing measures.

The measures discussed above, including travel restrictions, were put in place to safeguard the health and safety of the Company’s employees, customers, and suppliers, but have not limited the Company’s ability to maintain its operations. In addition, these alternative working arrangements have not adversely affected financial reporting systems, internal control over financial reporting or disclosure controls and procedures.

The advance of vaccinations has allowed the resumption of economic activities in some sectors, especially services, where there has been a reduction in isolation restrictions. Most schools in Brazil resumed on-site teaching in August 2021, and Company travel, which was previously restricted, also resumed as of the third quarter, following the best health and safety protocols.

The Company’s content production continues according to the scheduled curriculum calendar and the current educational material has been delivered to the schools according to their calendar for the year, enabling the Company to recognize revenues on these products.

F-10

With respect to the Company’s distribution and delivery capacity, which relies on third parties, the Company’s main suppliers did not raise any issues related to their ability to fulfill scheduled shipments or indicated the need to incur in any significant additional expenses.

As a result, as of September 30, 2021, the following events and transactions occurred during the period:

· The Company incurred additional expenses of R$ 1,646 during the nine months period ended September 30, 2021, related to health care in food and emotional health programs offered to the Company’s employees.

· The Company assessed the existence of potential impairment indicators and the possible impacts on the key assumptions and projections caused by the pandemic on the recoverability of long-lived assets and concluded that there are no indications that demonstrate the need to recognize a provision for impairment of long-lived assets in the consolidated financial statements.

· The Company obtained rent concessions, regarding leased buildings, that occurred as a direct consequence of the COVID-19 pandemic and were accounted as if they were not lease modifications. Therefore, no changes occurred in the expected useful lives and residual values of properties and equipment. For the nine months period ended September 30, 2021, the discount obtained was R$ 217.

· The Company’s revenue for the school year ended September 30, 2021 was 9% below the ACV booking for the school year period starting in October of the previous year to September of the current year.

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:

· 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.

F-11

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

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.

The purchase price allocation is subject to change during the period of completion of the determination of the fair value of intangible assets according to the timeframe defined by IFRS 3.

On March 12, 2021, the Company acquired control of Me Salva!, by acquiring 60.0% of the outstanding shares on the acquisition date.

For acquisition of remaining 40%: (i) R$ 22,196, representing the present value of the amount that will be paid in March 2025. Because the price is not fixed, the Company considers the payment as contingent consideration and the financial liability is measured at FVPL and no non-controlling interest has been recognized.

The Company did not recognize deferred taxes related to the business combination because the tax basis and the accounting basis, including fair value adjustments, were the same at the date of the business combination.

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$16,802 during the nine-month period ended September 30, 2021 (2020: R$ 13,610).

(b) Share-based compensation plan

Geekie Plan

Geekie has its own stock option plan that is granted to employees elected by Management and duly approved by the Board.

The first stock option plan was approved on December 19, 2017, with share-based compensation features to be settled in cash and not in equity. On November 27, 2020, the entity reassessed the fair value of the vested shares in the closing period and updated the liability against share-based compensation plan expenses, reducing the net assets acquired of the Geekie’s opening balance.

On December 1, 2020, after Geekie’s acquisition by Arco, the Company approved, new conditions for granting stock options in the total amount of 31,763 shares. The stock options are exercisable from the date of approval of the new grant agreement, with the vesting period on that date being considered fulfilled.

The new stock options plan is classified as cash settled since all Geekie’s employees have signed a mandatory contract to sell all the option to Arco at exercise date at the same price to be paid to non-controlling selling shareholders and liability is measured at fair value at the end of each reporting period until its effective settlement.

The exercise price of the options granted to all beneficiaries is R$ 82.91 as determined in the grant agreements. The beneficiary has the maximum period for exercising the options is up to March 31, 2022, under penalty of forfeiture.

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. This payable amount was reclassified to current liabilities in 2021, since its due to 2022.

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.

F-30

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 September 30, 2021:

	Number of restricted stock units
Outstanding at December 31, 2020		161,231
Granted (a)		251,491
Vested (b)		(159,452	)
Restricted stocks units transferred		(17,878	)
Effectively forfeited		(5,690	)
Estimated forfeited		(9,286	)
Outstanding at September 30, 2021		220,416

(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.

(b) Refers to the total number of shares whose vesting period was fulfilled as defined in the contract (anniversary date), but not yet transferred to the beneficiaries on September 30, 2021. Restricted Shares will be transferred to the participant only after the vesting period has been completed or in the event of contractual termination.

The total compensation expense for the nine-month period ended September 30, 2021, including taxes and social charges, was R$32,780, (R$25,716 of principal and R$7,064 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.

As of September 30, 2021, the Company transferred 9,841 investment shares under the Matching Program with an average price of R$ 191.1.

17 Earnings (loss) per share (EPS)

Basic

Basic EPS is calculated by dividing loss 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.

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 loss attributable to equity holders of the parent and the share data used in the basic and diluted EPS computations:

Capital expenditures consist of additions to property and equipment and intangible assets. There were no inter-segment revenues or costs in the nine-month periods ended September 30, 2021 and 2020.

Segment performance is evaluated based on segment profit and is measured consistently and on the same basis as profit or loss in the consolidated financial statements. General and administrative expenses, other income (expenses) net, finance result, share of profit (loss) of equity-accounted investees and income taxes are managed on a Company basis and are not allocated to operating segments.

There were no adjustments or eliminations in the profit or loss between segments. Adjustments and eliminations refer to transactions due between companies in the Core and Supplemental segments, such as: loans, accounts payable and accounts receivable. Segment assets and liabilities are measured on the same basis as in the financial statements. These assets and liabilities are allocated based on the operations of the segment.

(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.

F-44

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		September 30, 2021		December 31, 2020
				(unaudited)
Financial assets
Financial investments		Level 2		-		17,645
Investments at fair value		Level 1		9,810		9,654
Financial liabilities
Accounts payable to selling shareholders		Level 3		846,112		861,385

As of September 30, 2021, and December 31, 2020, 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-45

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 September 30, 2021 and 2020.

Recurring fair value measurements	Financial instruments – call options on equity method investments (assets)			Financial instruments – put options on equity method investments (liabilities)			Accounts payable to selling shareholders
As of December 31, 2019		35,946			(33,940	)		(328,668	)
Payment		-			-			3,696
Changes in accounts payable to selling shareholders		-			-			(19,872	)

Finalization of price allocation (Note 12.b)		-			-			66,952
As of September 30, 2021 (unaudited)		-			-			(846,112	)

(iv) Transfers between levels 2 and 3

During the nine-month periods ended September 30, 2021 and 2020, 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.

24 Commitments and contingencies

(i) Legal proceedings

The Company is party to labor and tax litigation in progress, which arise during the ordinary course of business. The provisions for probable losses arising from these matters are estimated and periodically adjusted by Management, supported by the opinion of its external legal advisors.

As of September 30, 2021, the Company was party to lawsuits classified as possible losses totaling R$ 8,745 (R$ 7,863 as of December 31, 2020), as shown below:

	September 30, 2021		December 31, 2020
		(unaudited)
Civil (a)		6,983		6,367
Labor (b)		1,762		1,496
Total		8,745		7,863

(a) The civil proceedings relate mainly to copyright and 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.

As the arbitration proceeding progresses the estimated amount payable by CBE to the non-controlling shareholder may be lower than the provision recorded, due to the disposition of the Investment Agreement that sets forth that the payment schedule of the purchase price shall be anticipated in case of an initial public offering. Conversely, the estimated amount payable by CBE to the non-controlling shareholder may be higher than the provision recorded in light of the claims asserted by the non-controlling shareholder.

F-47

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.

Therefore, in light of the current stage of the proceeding and the range of potential outcomes, the calculation methodology of the estimate has remained unchanged, consistent with the estimate previously calculated and reported.

Based on this analysis, the Company has recorded the provision of the amount considered the appropriate estimate of the amount of the purchase price under the Investment Agreement payable to the non-controlling shareholder. The provision is calculated based on the realized EBITDA for the school years of 2019 (first installment) and 2020 (second installment), both, net of debts, 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 course of the arbitration. Based on realized numbers, the liability increased by R$ 230 in 2021 and was recorded as financial expense as described in Note 13.a). During the nine-month period ended September 30, 2021, the Company recognized R$ 16,789 of interest related to the liability.

25 Transactions not involving cash

The Company carried out the non-cash activities in the nine-month period ended September 30, 2021, which are not reflected in the statement of cash flows, mainly related to the effects of lease contracts signed in the period as described in Note 11 and retained payments and acquisition from business combination in Note 3.

26 Subsequent events

Corporate restructuring

On October 1, 2021, the Company completed a corporate reorganization through the incorporation of Nave à Vela Ltda. by Companhia Brasileira de Educação de Sistemas de Ensino S.A.

Acquisition of COC and Dom Bosco learning systems

On October 1, 2021, Arco concluded the acquisition of 100% of the capital stock of COC and Dom Bosco. The payment terms set forth in the purchase agreement were updated upon closing of the transaction to a total purchase price of R$ 800,400, adjusted for COC’s and Dom Bosco’s cash and working capital positions as of September 30,2021. The net amount calculated was R$ 789, paid in a single installment on the transaction closing date.

F-48

Payment of the Positivo installment

On November 1, 2021, the Company paid the amount of R$ 186,138 related to the second installment of Positivo acquisition as described in Note 13.e).

Cancellation of Treasury Shares

On November 1, 2021, the Company repurchased 1,172,991 Class A Common Shares under the Repurchase Plan previously approved by the Board of Directors. On the same date, the Company canceled 750,000 Treasury Shares with the approval of the Board of Directors.

Loan agreement

On November 11, 2021, the subsidiary Geekie entered into a loan agreement in the amount of US$ 11,020 with an interest rate of 1.752% p.a. Additionally, Geekie entered into swap contracts with the lender, swapping the original interest rate to CDI + 1.7208%, avoiding any exchange risk. The loan payments will be paid quarterly in 12 installments, until October 28, 2024. The loan is to finance the acquisition of chromebooks, which are part of Geekie's educational offering.

Investment from Dragoneer and General Atlantic

On November 18, 2021 Arco entered into agreements led by affiliates of Dragoneer Investment Group LLC (“Dragoneer”), which have committed to make a US$100 million strategic investment, and General Atlantic Partners (Bermuda) J, L.P. (“General Atlantic”), which has committed to make a US$50 million strategic investment, through the purchase of convertible senior notes, subject to customary closing conditions.

Each note will be convertible at the option of the holder into Arco’s Class A common shares at the agreed conversion rate, which is equivalent to an initial conversion price of US$29 per share. The conversion price represents an approximately 65% premium to the trailing 30-day volume-weighted share price. Dragoneer and General Atlantic will beneficially own approximately 5.6% and 2.8%, respectively, of the total shares of the Company (on an as converted basis for the convertible senior notes).

The convertible notes mature in 7 years, on November 15, 2028, and bear interest at 8% per year fixed in Brazilian reais, payable quarterly in cash in arrears in United States dollars, therefore mitigating currency risk.

Arbitation process of International Scholl

On November 29, 2021, the arbitration panel issued a decision on the merits of the arbitration dispute filed by Mr. Ulisses Borges Cardinot, a 48.52% shareholder in International School, 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. (current name of PSD Educação S.A.) and Arco Educação S.A. The decision is under the ongoing review of financial and legal advisors of the company and its interpretation and execution will be further discussed in the award 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 shall 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. For further information, please see Note 24.
