Of the total aggregate stock consideration, 10,018,754 shares have already been delivered to Isaac's shareholders, of which 1,047,142 were from the Company's treasury shares, 8,971,612 were newly issued shares and the remaining shares in the total of 417,448 have been retained for a period of 18 months (“holdback period”) for future claims. The transaction resulted in a dilution of approximately 14.2% for Arco's Class A shareholders.

F-11

As part of the acquisition, the Company granted to Isaac's employees new share-based awards to replace Isaac’s share-based compensation awards. The replacement awards were divided between a stock option plan – SOP, described as the Arco Share Option Plan and restricted shares units – RSU, under Arco’s regular plan terms as mentioned in Note 13. The Company accounted for the replacement awards as modification of the original granted instruments. The Company recognized R$ 41,743 as part of the consideration transferred, related to the portion of the marked-based measure of the acquiree awards, which refers to pre-combination service, in accordance with IFRS 3.

The acquisition of Isaac significantly expands Arco’s footprint in Brazil’s education ecosystem by increasing the scope of its portfolio of products, making Arco a true one-stop-shop for its partner schools, while establishing closer relationships with families.

The founding shareholders of Isaac are subject to a lock-up period of 3 years from the closing date with respect to their Arco shares, with 1/3 of their shares being released each year.

At the date of acquisition, the carrying amount of the Company’s previously held interest was R$ 87,695 and its fair value was R$ 257,972, resulting in a gain of R$ 170,277, recognized as other income in the statement of income.

The Company has not recognized any 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.

Goodwill

The goodwill recognized on the acquisition was R$ 611,511 and it is not expected to be deductible for tax purposes after the Company merges the acquiree. For the purposes of impairment testing, the goodwill has been allocated to the Financial and Management Solutions operating segment.

The goodwill recognized is primarily attributable to the expected synergies and other benefits from combining the assets and activities of Isaac with those of the Company. The goodwill is based on the Business Plan prepared for purposes of the acquisition, and the principal business assumptions used were considered by management as appropriate.

Transaction costs

Transaction costs of R$ 18,528 were expensed and were included in general and administrative expenses, in the amount of R$ 13,159 in 2022 and R$ 5,369 in 2023.

(b) Measurement of fair value

The valuation techniques used for measuring the fair value of separate identified intangible assets acquired were as follows:

Asset acquired	Valuation technique
Non-compete agreement	With-and-without method The With-and-Without method consists of estimating the fair value of an asset by the difference between the value of this asset in two scenarios: a scenario considering the existence of the asset in question and another, considering its non-existence.
Trademarks	Relief-from-royalty method The relief-from-royalty method considers the discount estimated royalty payments that are expected to be avoided as a result of the educational platform being owned.
Software	Replacement cost The method considers the amount that an entity would have to pay to replace at the present time, according to its current worth.

(c) Revenue and profit contribution

The revenue and net loss included in the consolidated statements of income and comprehensive income from the acquisition date through the period end are presented below:

	June 30, 2023

From the date of acquisition, January 3, 2023, Isaac has contributed R$ 130,953 of revenue and R$ 45,093 of loss to the Company net profit from the continuing operations of Arco. Since the acquisition took place at the beginning of the year, revenue and profit from continuing operations would have been the same as presented in the statement of income.

Advances from customers

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

(b) Share-based compensation plan

Arco Share Option Plan - Stock options

On January 2, 2023, and in connection with the Isaac acquisition, our board of directors approved the Arco Share Option Plan.

The Arco Share Option Plan is administered by our board of directors and a designated committee, and eligible participants include Isaac employees. Pursuant to the Arco Share Option Plan, we have granted options to each participant at no cost to such participant, subject to the participant's continuance as an employee of any Company in Arco and its subsidiaries, including with respect to the dismissal of participants with or without cause or in the event of a change in our control, from the grant date until the end of the vesting period (“Vesting”). Participants in the Arco Share Option Plan are subject to a six-month lock up period from the date of acquisition of the shares.

The following table lists the inputs to the model used for the Arco Share Option Plan estimated on the grant date:

Dividend yield (%)	n/a
Expected volatility (%)	51.50
Risk-free interest rate (%)	3.17 to 3.37
Expected life of share options (years)	4.00
Weighted average share price (R$)	70.21
Model used	Black & Scholes

F-23

The expected life of the stock options is based on contractual terms and current expectations and is not necessarily indicative of exercise patterns that may occur. The expected volatility reflects the assumption that the historical volatility over a period similar to the life of the options is indicative of future trends, which may not necessarily be the actual outcome.

The Company recognized R$ 32,887 related to the pre-combination services portion in the consideration transferred regarding the stock options, due to acquisition of control in Isaac, in accordance with IFRS 3.

The following table illustrates the number and movements of share options during the six-month period ended June 30, 2023:

	Number of restricted stock units
Outstanding at December 31, 2022		-
Granted		782,471
Vested		(218,952	)
Estimated forfeited		(54,999	)
Outstanding at June 30, 2023		508,520

The vesting period is according to the following schedule:

Final vesting date	Quantity of stocks		Unvested shares, net of forfeitures
31/12/2023		175,256		158,151
01/01/2024		102,173		92,201

31/12/2026		24,418		22,035
Total		563,519		508,520

Restricted Shares Grant Plan – Regular Plan

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 Arco and its subsidiaries from the grant date until the end of the vesting period (“Vesting”). If a participant leaves the group, or does not achieve the 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. The total amount will be calculated based on the performance 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 fair value of the restricted shares is equal to the market price of the underlying shares on the date of grant.

The Company recognized R$ 8,856 related to the pre-combination services portion in the consideration transferred regarding the restricted shares granted, due to acquisition of control in Isaac, in accordance with IFRS 3.

Basic earnings per share 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.

Diluted earnings per share reflects the potential dilution that could occur if securities or other contracts to issue shares were exercised into shares. In calculating diluted earnings per share, the numerator is adjusted for the effect of interest expense, exchange variation and changes in the fair value of the embedded conversion feature of the convertible notes disclosed in notes 10 and 11 (only if dilutive) and the denominator is increased to include the number of potentially dilutive Class A common shares factual to be outstanding during the period.

F-28

In addition, the Company has share-based compensation plans (see Note 13) and holdback shares related to Isaac’s acquisition (see Note 3) that are also considered in the calculation of diluted earnings per share if they have a dilutive effect.

(a) Provision for expected losses from Isaac’s operation is accounted for as cost of services in our financial statements as they are accounted under accrual methodology and measured at amortized cost. Expected credit losses (“ECLs”) are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that Isaac expects to receive. Isaac recognizes a loss allowance based on lifetime ECLs, provision matrix and days past due at each reporting date.

(b) Refers to gain with step acquisition from Isaac business combination, as disclosed in Note 3.

(c) Refers to net result from Edupass sale in the second quarter of the year, as disclosed in Note 1.2.

(a) Considering that Arco Platform Ltd, is domiciled in the Cayman Islands and there is no income tax in that jurisdiction, the combined statutory tax rate of 34% demonstrated above is the current rate applied to Arco Brasil S.A. which is the holding Company of all operating entities of Arco Platform, in Brazil.

(b) Refers to the effect of 34% on the share of loss of equity-accounted investees for the period.

(c) Brazilian tax law establishes that companies that generate gross revenues of up to R$ 78,000 in the prior fiscal year may calculate income taxes as a percentage of gross revenue, using the presumed profit income tax regime. The Company’s subsidiaries adopted this tax regime and the effect of the presumed profit of subsidiaries represents the difference between the taxation based on this method and the amount that would be due based on the statutory rate applied to the taxable profit of the subsidiaries.

(d) Permanent differences of non-deductible expenses.

(e) Related to the effect of 34% of Geekie’s share-based compensation plan expenses, that was paid in June 2022, when Arco acquired the remaining interest.

(f) Refers to the effect of 34% of Arco Platform net income, which is not taxable, as mentioned in item a). The net income for the six-month periods ended June 30, 2023 is mainly related to gain from the convertible senior notes foreign exchange, fair value adjustment and interest provisioned (R$ 49,827) and gain from the step acquisition (R$ 170,277).

Derivative assets and liabilities

The Company maintains put options on certain 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.  The Company decided not to designate these foreign currency contracts as hedge accounting relationships. Consequently, all changes in the fair values of such contracts are recognized in the statement of income.

All financial instruments for which fair value is recognized or disclosed are categorized within the fair value hierarchy, based on the lowest level input that is significant to the fair value measurement as a whole, as follows:

Level 1 — Quoted (unadjusted) market prices in active markets for identical assets or liabilities;

Level 2 — Valuation techniques for which the lowest level input that is significant to the fair value measurement is directly or indirectly observable;

Level 3 — Valuation techniques for which the lowest level input that is significant to the fair value measurement is unobservable.

For assets and liabilities that are recognized at fair value on a recurring basis, the Company determines whether transfers have occurred between levels in the hierarchy by re-assessing categorization (based on the lowest level input that is significant to the fair value measurement as a whole) at the end of each reporting period.

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 hires specialists to measure fair value of certain financial assets independently.

Set out below are the significant unobservable inputs to valuation as of June 30, 2023:

	Valuation technique	Significant unobservable inputs	Range (weighted average)	Sensitivity of the input to fair value
Derivative financial liabilities	Black & Scholes	Volatility	%	1% increase/(decrease) in the volatility would result in increase/(decrease) in fair value by R$ 2,803

There were no changes in the Company’s valuation processes, valuation techniques, and types of inputs used in the fair value measurements during the period.

22 Commitments and contingencies

Arbitration process of International School

On September 19, 2019, Mr. Ulisses Borges Cardinot, the non-controlling shareholder in the 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 amount to be calculated in accordance with the decision is under ongoing discussion 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.

Considering the arbitration proceeding and 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 payable to the non-controlling shareholder under the Investment Agreement. 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 six-month period ended June 30, 2023, the Company recognized R$ 25,915 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.

The Founders, who beneficially own all of the Company's Class B common shares, the Rollover Shareholders and the Bidders have agreed to vote all of the Company's common shares they beneficially own, which represent approximately 91% of the voting power of the outstanding common shares as of the date of the Agreement, in favor of the authorization and approval of the Agreement, the Merger and the other transactions contemplated by the Agreement. Accordingly, they own a sufficient number of common shares to assure shareholder approval. Upon completion of the Merger, Arco will become a privately held company and its Shares will no longer be listed on the NASDAQ Global Market.
