4Q22 and 2022 Highlights

¹ Recent M&A activities refer to businesses acquired in 2021 (Me Salva, Eduqo, Edupass, COC, Dom Bosco) and 2022 (PGS, Mentes).

² As part of the acquisition, Arco acquired Geekie’s management future stake in Geekie, resulting from the exercise of their existing SOP. The fair value of the SOP was calculated using the same valuation method as the accounts payable to selling shareholders for the acquisition of the remaining interest at the time, resulting in the final transaction price, which were updated quarterly for Geekie’s most recent fair value, until its effective settlement in 2022. As a result of Geekie’s strong commercial performance in 2021, its updated fair value impacted both the SOP (registered in the “Share-based compensation plan expenses” line) and accounts payable to selling shareholders. In 2021, such impact was R$37 million in the “Share-based compensation plan expenses” line.

Key Business Metrics

ACV Bookings: we define ACV Bookings as the revenue we would contractually expect to recognize from a partner school in each school year pursuant to the terms of our contract with such partner school, assuming no further additions or reductions in the number of enrolled students that will access our content at such partner school in such school year (we define “school year” for purposes of calculation of ACV Bookings as the twelve-month period starting in October of the previous year to September of the mentioned current year). We calculate ACV Bookings by multiplying the number of enrolled students at each partner school with the average ticket per student per year; the related number of enrolled students and average ticket per student per year are each calculated in accordance with the terms of each contract with the related partner school.

Non-GAAP Financial Measures

To supplement the Company's condensed consolidated financial statements, which are prepared and presented in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board—IASB, we use Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Net Income Margin and Managerial Free Cash Flow and which are non-GAAP financial measures.

We calculate Adjusted EBITDA as profit (loss) for the year (or period) plus/minus income taxes, plus/minus finance result, plus depreciation and amortization, plus/minus share of (profit) loss of equity-accounted investees, plus share-based compensation plan and restricted stock units, plus provision for payroll taxes (restricted stock units), plus/minus M&A related (gains) losses and expenses, plus non-recurring expenses and plus effects related to COVID-19 pandemic. We calculate Adjusted EBITDA Margin as Adjusted EBITDA divided by Net Revenue.

We calculate Adjusted Net Income as profit (loss) for the year, plus amortization of intangible assets from business combinations (which refers to the amortization of the following intangible assets from business combinations: (i) rights on contracts, (ii) customer relationships, (iii) educational system, (iv) trademarks, (v) non-compete agreement and (vi) software resulting from acquisitions), plus/minus changes in accounts payable to selling shareholders (which refers to changes in fair value of contingent consideration and accounts payable to selling shareholders—finance costs), plus interest income (expenses), net (which refers to interest expenses related to accounts payable to selling shareholders from business combinations adjusted by fair value), plus share-based compensation plan, restricted stock units and related payroll taxes (restricted stock units), plus/minus non-cash adjustments related to Derivatives and Convertible Notes, plus M&A expenses (expenses related to acquisitions, and legal services mainly due to International School arbitration), minus other changes to equity accounted on investees, plus non-recurring expenses, which are related to

consulting expenses for Sarbanes-Oxley implementation, plus effects related to COVID-19 pandemic, which includes the revision of the Company’s estimated credit losses from its trade receivables based on expected increases in financial default and in unemployment rates in Brazil for the year and plus/minus changes in current and deferred tax recognized in statements of income applied to all adjustments to net income (which refers to tax effects of changes in deferred tax assets and liabilities recognized in profit or loss corresponding to financial instruments from acquisition of interests, tax benefit from tax deductible goodwill, share-based compensation and amortization of intangible assets).

For purposes of the calculation of Adjusted Net Income for the year ended December 31, 2021, we have excluded the following adjustments that we applied to the calculation of Adjusted Net Income for prior periods: (i) Interest income (expenses) linked to a fixed rate (we will maintain the adjustment for Interest income (expenses) that refers to adjustments by fair value); (ii) Foreign exchange effects on cash and cash equivalents and (iii) share of loss of equity accounted investees and. These adjustments will not be applied to the calculation of Adjusted Net Income going forward. We believe that eliminating these adjustments from our calculation of Adjusted Net Income for the year ended December 31, 2021 and going forward does not impact our investors’ ability to assess our results of operations. We have not retroactively restated Net Adjusted Income for the periods prior to 2021.

We calculate Managerial Free Cash Flow as Net Cash Flows from Operating activities, less acquisition of property and equipment, less acquisition of intangible assets, less M&A-related payments. We consider Free Cash Flow to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by operating activities and cash used for investments in property and equipment required to maintain and grow our business.

We understand that, although Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Net Income Margin and Managerial Free Cash Flow are used by investors and securities analysts in their evaluation of companies, these measures have limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results of operations as reported under IFRS. Additionally, our calculations of Adjusted EBITDA, Adjusted EBITDA Margin, Adjusted Net Income, Adjusted Net Income Margin and Managerial Free Cash Flow may be different from the calculation used by other companies, including our competitors in the education services industry, and therefore, our measures may not be comparable to those of other companies.
