[**Table of Contents**](#TOC)

On September 8, 2020, we completed a follow-on public offering, consisting of 2,500,000 Class A common shares issued and sold by us. The public offering price was US$44.80 per Class A common share. We received net proceeds of US$109.8 million, after deducting US$2.2 million in underwriting discounts and commissions.

On January 6, 2021, our 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, we 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, our Board of Directors approved the increase of the share repurchase limit of our Repurchase Program to up to 2.5 million of our outstanding Class A common shares in the open market, based on prevailing market prices, or in privately negotiated transactions, continuing until the earlier of the completion of the repurchase or January 6, 2023, depending upon market conditions. The Repurchase Program expired on January 6, and as of such date, we had purchased an aggregate of 2,031,186 Class A common shares for a total of approximately US$46.8 million under the Repurchase Program. On November 1, 2021, we cancelled 750,000 treasury shares with the approval of our Board of Directors.

On August 1, 2020, we completed a corporate reorganization through the incorporation of Positivo Soluções Didáticas Ltda., or Positivo, and Editora Piá Ltda. On January 1, 2021, we completed a corporate reorganization through the incorporation of Arco Ventures S.A. On July 1, 2021, we completed a corporate reorganization through the incorporation of Barra Américas Editora Ltda., Distribuidora de Material Didático Desterro Ltda., SAS Sistema de Ensino Ltda. and SAS Livrarias Ltda. On October 1, 2021, we completed a corporate reorganization through the incorporation of Nave à Vela Editora e Comercializadora de Materiais Educacionais S.A. On May 1, 2022, we completed a corporate reorganization through the incorporation of P2D Educação Ltda. On October 1, 2022, we completed a corporate reorganization through the incorporation of Geekie Desenvolvimento de Software S.A. All companies were incorporated by Companhia Brasileira de Educação e Sistemas de Ensino S.A. (formerly known as PSD Educação S.A. (until 2021), as EAS Educação S.A. (until 2020) and SAS Educação S.A. (until 2017)), or CBE, and were under our common control and the incorporated assets and liabilities of the respective companies were recorded at their carrying amounts. The incorporations were part of a tax planning strategy to enable us to obtain tax benefits from the amortization of fair value adjustments and goodwill resulting from business combinations. Furthermore, we are currently implementing certain additional changes to the organizational structure of certain of our operating subsidiaries in Brazil. This reorganization will be an internal corporate reorganization and is not expected to affect us on a consolidated basis.

On December 1, 2021, we issued US$150 million in senior notes convertible into our Class A common shares in the amount of: (i) US$100 million to Arcade GF II Holdings, LLC and Arcade OF V Holdings, LLC, entities affiliated with Dragoneer Investment Group, or Dragoneer; and (ii) US$50 million to General Atlantic Partners (Bermuda) H, L.P., an entity affiliated with General Atlantic, L.P., or General Atlantic. The convertibles notes bear interest at 8% per annum in fixed Brazilian reais and mature on November 15, 2028. Each note is convertible at the option of the holder into our 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 a premium of approximately 65% to the trailing 30-day volume-weighted share price at the time of signing the investment agreements for the convertible notes.

[**Table of Contents**](#TOC)

On November 30, 2022, our Board of Directors received a preliminary non-binding proposal from General Atlantic and Dragoneer to acquire all of our outstanding Class A common shares not held by General Atlantic, Dragoneer or our Founding Shareholders, or the Going Private Transaction, at a purchase price payable in cash and equal to US$11.00 per Class A common share (which represented a premium of approximately 22% over the closing price of US$9.04 per Class A common share as of November 30, 2022). Pursuant to the terms of the non-binding proposal, the Founding Shareholders would roll over 100% of their Class A common shares and Class B common shares into the Going Private Transaction, and following closing of the Going Private Transaction, the Founding Shareholders would maintain their current economic and voting interests in the Company. On January 26, 2023, the Company announced that the Board of Directors had formed a special committee consisting of four independent directors to evaluate and consider the non-binding proposal and any potential alternative transactions, and to engage in any other actions to further the interests of the holders of our Class A common shares. As of the date of this annual report, the special committee evaluation of the non-binding proposal and any potential alternative transactions is ongoing. For more information, see "Item 4. Information on the Company—A. History and Development of the Company—Proposed Going Private Transaction."

#### Financial Information in U.S. Dollars
Solely for the convenience of the reader, we have translated some of the real amounts included in this annual report from reais into U.S. dollars. You should not construe these translations as representations by us that the amounts actually represent these U.S. dollar amounts or could be converted into U.S. dollars at the rates indicated. Unless otherwise indicated, we have translated real amounts into U.S. dollars using a rate of R$5.218 to US$1.00, the commercial selling rate for U.S. dollars as of December 31, 2022, as reported by the Central Bank. See "Item 5. Operating and Financial Review and Prospects—A. Operating results—Exchange Rates" for more detailed information regarding translation of reais into U.S. dollars and for historical exchange rates for the Brazilian real.

#### Special Note Regarding Non-GAAP Financial Measures
This annual report presents our Adjusted EBITDA, Adjusted Net Income and Free Cash Flow information for the convenience of investors. Adjusted EBITDA, Adjusted Net Income and Free Cash Flow are the key performance indicators used by us to measure financial operating performance. Our management believes that these Non-GAAP financial measures provide useful information to investors and shareholders as it is a necessary metric to better understand the Company's liquidity or operating ratios. We also use these measures internally to establish budgets and operational goals to manage and monitor our business, evaluate our underlying historical performance and business strategies and to report our results to the board of directors.

We calculate Adjusted EBITDA as profit (loss) for the year 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, restricted stock units and related payroll taxes (restricted stock units), plus M&A expenses (which refers to non-recurring expenses related to the acquisitions of the year), minus other changes to equity accounted investees (which refers to gains related to capital contribution from others on investees leading to an increase in equity of the investee), plus non-recurring expenses (which are related to consulting expenses in respect of the Sarbanes-Oxley Act, or SOX implementation and corporate restructuring), plus effects related to COVID-19 pandemic (only for 2020 and 2021) (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).

We calculate Adjusted Net Income as profit (loss) for the year plus share-based compensation plan, restricted stock units and related payroll taxes (restricted stock units), plus M&A expenses (which refers to non-recurring expenses related to the acquisitions of the year), minus other changes to equity accounted investees (which refers to gains related to capital contribution from others on investees leading to an increase in equity of the investee), plus non-recurring expenses (which are related to legal services (mainly in connection with the International School arbitration) and consulting expenses for SOX implementation), plus effects related to COVID-19 pandemic (only for 2020 and 2021) (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 period), 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 fair value of derivative instruments (which refers to (i) changes in fair value of derivative instruments—finance income, plus (ii) changes in fair value of derivative instruments—finance costs), 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/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).

[**Table of Contents**](#TOC)

For purposes of the calculation of Adjusted Net Income for the year ended December 31, 2022 and December 31, 2021, we have excluded the following adjustments that we applied to the calculation of Adjusted Net Income for December 31, 2020 or prior periods: (i) foreign exchange effects on cash and cash equivalents; (ii) share of loss of equity-accounted investees; and (iii) interest income (expenses) linked to a fixed rate (we will maintain the adjustment for interest income (expenses) that refers to adjustments by fair value). These adjustments will not be applied going forward. We believe that eliminating these adjustments from our calculation 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 Free Cash Flow as net cash flows from operating activities less acquisition of property and equipment less acquisition of intangible assets. 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 and intangible assets required to maintain and grow our business.

We understand that although Adjusted EBITDA, Adjusted Net Income and 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 Net Income and Free Cash Flow may be different from the calculations 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.

For a reconciliation of our non-GAAP measures, see "Item 5. Operating and Financial Review and Prospects—A. Operating results—Reconciliations for Non-GAAP Financial Measures."

#### Special Note Regarding ACV Bookings
This annual report presents our Annual Contract Value bookings, or ACV Bookings, for the convenience of investors. ACV Bookings represents our customers' commitments to pay for our solutions offerings. We believe it is a meaningful indicator of demand for our platform and the market's response to it. We believe ACV Bookings is a helpful metric because it is designed to show amounts that we expect to be recognized as revenue for the 12-month period between October of one fiscal year through September of the following fiscal year. For our B2B2C Core Curriculum and Supplemental Content Solutions, which currently represent most of our results, we deliver our educational materials to our partner schools for their convenience in the last calendar quarter of each year, so that our partner schools can prepare their classes in advance prior to the start of the following school year in January. As a result, our results of operations for the last quarter of a given fiscal year contain revenues relating to the following school year, which reflects the content that has been delivered prior to the start of the new fiscal year. Therefore, ACV Bookings conveys information that has predictive value for subsequent months, and which may not be as clearly conveyed or understood by simply analyzing our revenues in our income (loss), especially in view of our recent growth.

We define ACV Bookings as the revenue we would contractually expect to recognize in each school year pursuant to the terms of our contracts, assuming no further additions or reductions in the number of students that will access our content in such school year. ACV Booking is a non-accounting managerial operating metric and is not prepared in accordance with IFRS. We calculate ACV Bookings by multiplying the number of students that will access our content by the average ticket per student per year; the related number of students and average ticket per student per year are each calculated in accordance with the terms of each contract. For our B2B2C Core Curriculum and Supplemental Content Solutions, although our contracts with our partner schools are typically for three-year terms, we record one year of revenue under such contracts as ACV Bookings. For example, if a school signs a three-year contract with us to provide our Core Curriculum solution to 100 students for a contractual fee of $100 per student per year, we record $10,000 as ACV Bookings, not $30,000.

[**Table of Contents**](#TOC)

For our B2B2C Core Curriculum and Supplemental Content Solutions, we measure our ACV Bookings monthly throughout the school year, starting in November of the preceding fiscal year. Pursuant to the terms of our contracts with our partner schools, they are required, by the end of November of each year, to provide us with an estimate of the number of enrolled students that will access our content in the next school year. Since we allow our partner schools to make small adjustments to their estimates to account for late admissions and early dropouts, this number may fluctuate slightly until the end of March in each year, when it becomes more accurate. Accordingly, we believe this metric is most accurately reflected as of the end of March in each year, and in this annual report, we refer to our ACV Bookings as of March 30, 2023 and as of March 31, 2022, 2021 and 2020 as our ACV Bookings.

Notwithstanding the above, after March 31 in a calendar year, our partner schools may experience additional admissions and/or dropouts up to September 30 of such year, which explains the difference between the ACV Bookings and the revenue recognized for such school year. In years prior to the COVID-19 pandemic, the difference between our ACV Bookings and the revenue recognized for the school year was not material, demonstrating the predictability of our business. However, during 2020 and 2021 and as result of the impacts of the COVID-19 pandemic, our partner schools experienced atypical dropout rates from March 31 to September 30, and the difference between our ACV Bookings and the revenue recognized for each school year was -4% and -9%, respectively. The dynamics mentioned above also impacted the number of enrolled students in our partner schools. In 2022, we resumed our pre-COVID-19 trends and recognized 100% of our ACV Bookings for the school year.

We understand that, although ACV Bookings may be used by investors and securities analysts in their evaluation of companies, it has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results of operations as reported under IFRS.

#### Summary of Risk Factors
An investment in our Class A common shares is subject to a number of risks, including risks relating to our business and industry, risks relating to Brazil and risks relating to our Class A common shares. The following list summarizes some, but not all, of these risks. Please read the information in the section entitled "Risk Factors" for a more thorough description of these and other risks.

[**Table of Contents**](#TOC)

***Certain Risks Relating to Our Business and Industry***

●  ***Our operations and results have been and may be negatively impacted by the coronavirus (COVID-19) outbreak.*** The initial measures of restrictions taken by Brazilian states and local authorities directly impacted the education industry by indefinitely postponing on-site school activities. Nonetheless, in 2021 private schools resumed classes using a hybrid model, with on-site and online classes, and in 2022 private schools resumed in-person classes with no restrictions. In addition, the Company did not suspend its activities at any time and its workforce continued to work remotely throughout 2021, and gradually returned to working on site in 2022 in accordance with health and safety protocols and social distancing guidelines. 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 or to reasonably estimate its impact on Arco's results of operations, cash flows or financial condition.

●  ***We face significant competition in each program we offer and each geographic region in which we operate.*** If we experience increasing consolidation in the K-12 school industry in Brazil or if we fail to compete efficiently, we may lose market share and our profitability may be adversely affected. We compete directly with private education platform providers and indirectly with certain traditional educational content providers. Our competitors may begin to offer educational solutions similar to or better than those offered by us, have access to more funds, be more prestigious or well-regarded within the academic community, or charge lower fees. If we are unable to maintain our competitive position or otherwise respond to competitive pressures effectively, we may lose our market share, our profits may decrease, and we may be adversely affected.

●  ***We may not be able to update, improve or offer the content of our existing educational platform on a cost-effective basis.*** **  Our educational platform is designed to offer a complete suite of turnkey curriculum solutions intended to prepare the primary and secondary education students at our partner schools to sit the ENEM (which is equivalent to the Gaokao in China and loosely comparable to the SAT in the United States), for entry into post-secondary educational institutions and which is also used by the MEC and the market to evaluate Brazilian public and private schools. If we do not adequately modify our educational platform in response to market demand, whether due to financial restrictions, technological changes or otherwise, our ability to attract new schools and retain partner schools may be impaired and we may be materially adversely affected.

● Our business depends on the continued success of our brands, and if we fail to maintain and enhance the recognition of our brands, we may face difficulty increasing our network of partner schools, and our reputation and operating results may be harmed. We believe that market awareness of our brands, SAS Plataforma de Educação, or SAS, SAE Digital, Sistema Positivo de Ensino, or SPE, Sistema COC, or COC, International School, Escola da Inteligência, among others, has contributed significantly to the success of our business. If our marketing initiatives are not successful or become less effective, if we are unable to further enhance our brand recognition, or if we incur excessive marketing and promotion expenses, or if our brand image is negatively impacted by any negative publicity, we may not be able to attract new partner schools successfully or efficiently, and our business and results of operations may be materially and adversely affected. In addition, if any partner school using our educational platforms engages in unlawful activities or uses our educational platforms in an unauthorized manner, the general public may associate such school's behavior with our brand, generating negative publicity that may adversely affect our reputation.

● If we continue to grow, we may not be able to appropriately manage the expansion of our business and staff, the increased complexity of our software and platforms, or grow in our addressable market. **  We are currently experiencing a period of significant expansion and may face, as a result, certain expansion-related issues, such as cash flow management, corporate culture, IT integration and internal controls, among others. These issues and the significant amount of time spent on addressing them may result in the diversion of our management's attention from other business issues and opportunities. We cannot assure you that our current and planned platform and systems, procedures and controls, personnel and third-party relationships will be adequate to support our future operations. In addition, our continuous expansion places a significant strain on management and on our operational and financial resources, which strain is expected to continue. Our failure to manage growth effectively could seriously harm our business, results of operations and financial condition.

[**Table of Contents**](#TOC)

● An increase in delays and/or defaults in the payment of amounts owed to us by partner schools may adversely affect our income and cash flow. **  Because the historical information included elsewhere in this annual report may not be representative of our results as a consolidated company, investors may have limited financial information on which to evaluate us, their investment decision, and our prior performance.

●  ***An increase in delays and/or defaults in the payment of tuition fees may adversely affect our income and cash flows.*** We depend on the full and timely payment of the amounts owed to us by partner schools. Our partner schools may face financial difficulties, and in certain cases, insolvency, or bankruptcy. An increase in payment delinquency or default by partner schools may have a material adverse effect on our cash flows and our business, including our ability to meet our obligations, and in certain circumstances, we may decide to terminate our contracts with such partner schools, increasing our attrition rates.

***Certain Factors Relating to Brazil***

●  ***The Brazilian federal government has exercised, and continues to exercise, significant influence over the Brazilian economy.*** This involvement as well as Brazil's political, regulatory, legal and economic conditions could harm us and the price of our Class A common shares. **  The Brazilian government's actions to control inflation and other policies and regulations have often involved, among other measures, increases or decreases in interest rates, changes in fiscal policies, wage and price controls, foreign exchange rate controls, blocking access to bank accounts, currency devaluations, capital controls and import and export restrictions. Uncertainty over whether the Brazilian federal government will implement reforms or changes in policy or regulation affecting these or other factors in the future may affect economic performance and contribute to economic uncertainty in Brazil, which may have an adverse effect on our activities and consequently our operating results and may also adversely affect the trading price of our Class A common shares.

●  ***Economic uncertainty and political instability in Brazil may harm us and the price of our Class A common shares.*** **  Political crises have affected and continue to affect the confidence of investors and the general public which have historically resulted in economic deceleration and heightened volatility in the securities offered by companies with significant operations in Brazil.

● Inflation and certain measures by the Brazilian government to curb inflation have historically harmed the Brazilian economy and Brazilian capital markets, and high levels of inflation in the future would harm our business and the price of our Class A common shares. **  Inflation, policies adopted to curb inflationary pressures and uncertainties regarding possible future governmental intervention have contributed to economic uncertainty and heightened volatility in the Brazilian capital markets.

●  ***Exchange rate instability may have adverse effects on the Brazilian economy, us and the price of our Class A common shares.*** **  The Brazilian government has implemented various economic plans and used various exchange rate policies, including sudden devaluations, periodic mini-devaluations (during which the frequency of adjustments has ranged from daily to monthly), exchange controls, dual exchange rate markets and a floating exchange rate system. Depending on the circumstances, either devaluation or appreciation of the real relative to the U.S. dollar and other foreign currencies could restrict the growth of the Brazilian economy, as well as our business, results of operations and profitability.

●  ***Infrastructure and workforce deficiency in Brazil may impact economic growth and have a material adverse effect on us.*** Growth is limited by inadequate infrastructure, including potential energy shortages and deficient transportation, logistics and telecommunication sectors, general strikes, the lack of a qualified labor force, and the lack of private and public investments in these areas, which limit productivity and efficiency.

● Developments and the perceptions of risks in other countries, including other emerging markets, the United States and Europe, may harm the Brazilian economy and the price of our Class A common shares. The market for securities offered by companies with significant operations in Brazil is influenced by economic and market conditions in Brazil and, to varying degrees, market conditions in other Latin American and emerging markets, as well as the United States, Europe, and other countries, including as a result of the war between Russia and Ukraine. To the extent the conditions of the global markets or economy deteriorate, the business of companies with significant operations in Brazil may be harmed.

***Certain Factors Relating to Our Class A Common Shares***

● The Founding Shareholders, our largest group of shareholders, own 100% of our outstanding Class B common shares, which represents 90.7% of the voting power of our issued share capital, and will control all matters requiring shareholder approval. **  This concentration of ownership and voting power limits your ability to influence corporate matters. As long as the Founding Shareholders continue to beneficially own a sufficient number of Class B common shares, even if they beneficially own significantly less than 50% of our outstanding share capital, acting together, they will be able to effectively control our decisions. However, if our Class B common shares at any time represent less than 10% of the total number of shares in the capital of the Company outstanding, the Class B common shares then outstanding will automatically convert into Class A common shares.

● There can be no assurance that any definitive offer will be made with respect to the Going Private Transaction, that any agreement will be executed or that this or any other transaction will be approved or consummated. Potential uncertainty involving the proposed Going Private Transaction may adversely affect our business and the market price of our Class A common shares. In addition, if any definitive offer is made by General Atlantic or Dragoneer, we may be subject to various restrictions under those agreements on the conduct of our business prior to the completion of the transaction, which may delay or prevent us from undertaking business opportunities that may arise pending completion of the transaction.

● Our Articles of Association contain anti-takeover provisions that may discourage a third-party from acquiring us and adversely affect the rights of holders of our Class A common shares. Our Articles of Association contain certain provisions that could limit the ability of others to acquire our control, including a provision that grants authority to our board of directors to establish and issue from time to time one or more series of preferred shares without action by our shareholders and to determine, with respect to any series of preferred shares, the terms and rights of that series.

● If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research, about our business, the price of our Class A common shares and our trading volume could decline. The trading market for our Class A common shares depends in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who cover us downgrade our Class A common shares or publish inaccurate or unfavorable research about our business, the price of our Class A common shares would likely decline.

●  ***We do not anticipate paying any cash dividends in the foreseeable future.*** We currently intend to retain our future earnings, if any, for the foreseeable future, to fund the operation of our business and future growth. We do not intend to pay any dividends to holders of our Class A common shares. As a result, capital appreciation in the price of our Class A common shares, if any, will be your only source of gain on an investment in our Class A common shares.

#### Certain Factors Relating to Our Business and Industry

#### Our operations and results have been and may be negatively impacted by the coronavirus (COVID-19) outbreak.
In December 2019, a novel strain of COVID-19 started to spread and reached over 150 countries, including China, Italy, U.S. and Brazil. On March 11, 2020, the World Health Organization, revised the classification of COVID-19 from an epidemic (when a disease spreads through a specific community or region) to a pandemic, which according to World Health Organization's definition is when there is a worldwide spread of a new disease. The classification of the disease as a pandemic was motivated by the rapid increase in the number of cases and the number of affected countries on all continents, triggering measures by governments, companies, and societies to contain the advances of COVID-19. The measures vary from country to country in quantity and degree of severity but in Brazil basically involve: (1) recommendations to adopt voluntary isolation (avoid going out on the streets, avoiding crowds, avoiding physical contact with other people, etc.); (2) internal restrictions regarding the movement of people; (3) closing of schools; (4) closing of public places (parks and leisure centers); (5) closures of shopping malls, bars and restaurants; (6) adoption of remote working practices (home office) by companies, whenever possible and permitted by their activities; (7) restriction and/or suspension of trade in non-essential goods and services in the context of COVID-19 (while supermarkets, drugstores, gas stations and other essential services remain available); (8) purchase restrictions for certain essential items to avoid scarcity; (9) interruption of production activities of

[**Table of Contents**](#TOC)

consumer items not essential to combat the pandemic; (10) restriction on the delivery of products to homes other than essentials; (11) compulsory reduction of working hours; (12) cancellation of public events; and (13) other restrictive measures.

The initial measures of restrictions taken by Brazilian states and local authorities directly impacted the education industry by indefinitely postponing on-site school activities. With increased vaccination rates, including among children aged between five and eleven years, most private schools in Brazil resumed regular on-site classes in 2021, or adopted a hybrid learning method by mixing on-site and online classes, depending on local or statewide restrictions. Nonetheless, despite vaccination efforts, new variants of COVID-19 emerged, including the omicron variant, which impacted the number of hospital admissions and led to the adoption of further restrictive measures in some countries to contain the pandemic.

Nonetheless, in 2021 private schools resumed classes using a hybrid model, with on-site and online classes, and in 2022 private schools resumed in-person classes with no restrictions. In addition, the Company did not suspend its activities at any time and its workforce continued to work remotely throughout 2021, and gradually returned to working on site in 2022 in accordance with health and safety protocols and social distancing guidelines.

As a result, during 2020 and 2021 we made additional investments in IT and network infrastructure; incurred additional expenses for cleaning and disinfecting the installations; purchased alcohol and masks; and 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 to facilitate the diagnosis of COVID-19. The Company also delivered chairs, computers, and work kits to its employees. Additionally, to support schools, since day one, the Company has made available an integrated platform with daily live classes to all students, webinars, broadcast, and remote support to maintain student learning with the social distancing measures. The measures discussed above, including travel restrictions, were put in place in 2020 and 2021 to safeguard the health and safety of our 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.

Our content production continues according to the scheduled curriculum calendar and the current educational material has been delivered to the schools according to the school calendar for the year, enabling us to recognize the revenues on these products. With respect to the distribution and delivery capacity, which relies on third parties, our principal vendors responsible for the printing of educational material did not raise any issues related to their ability to fulfill scheduled shipments or with respect to the incurrence of any significant additional expenses related to the COVID-19 outbreak.

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 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.

● A change in the fair value of financial instruments.

● The renegotiation of loans and lease agreements to ensure the continued strength of the Company's financial position.

In addition, should new variants emerge and result in further hospitalizations and medical conditions, restrictive governmental measures may be reestablished, including the prohibition of non-essential activities and lockdowns, which may adversely affect our financial condition and results of operations.

***We face significant competition in each program we offer and each geographic region in which we operate. If we experience increasing consolidation in the K-12 school industry in Brazil or if we fail to compete efficiently, we may lose market share and our profitability may be adversely affected.***

We compete directly with private education platform providers and indirectly with certain traditional educational content providers. Brazil's antitrust authority, the Administrative Council for Economic Defense (*Conselho Administrativo de Defesa Econômica*), or CADE, has a consolidated decision-making practice to the education industry. For example, in September 2021, it approved a transaction between "CBE" and "Pearson Education do Brasil", in which it reaffirmed the relevant market definition related to information collected from the market test. Accordingly, CADE understands that the (1) relevant market of "educational systems" (which includes several educational services, e.g., teachers training platforms, digital and printed content and technological platforms) is different from the (2) relevant market of "textbooks and other classroom materials" (which is referred to in this annual report as "traditional educational content"). Nonetheless, the authority acknowledged that the providers of "textbooks and other classroom materials" compete, to a certain extent, with "educational systems" providers. Our competitors may begin to offer educational solutions similar to or better than those offered by us, have access to more funds, be more prestigious or well-regarded within the academic community, or charge lower fees. To compete effectively, we may be required to reduce our fees that we charge partner schools or increase our operating expenses to retain partner schools or attract new schools or to pursue new market opportunities. As a result, our revenues and profitability may decrease. We cannot assure you that a migration from traditional education content providers to education platform providers will be successful in the future, or that we will be able to compete successfully against our current or future competitors. Moreover, at present, there have been certain isolated cases of market consolidation in the private primary and secondary, or K-12, industry in Brazil. If such industry consolidation intensifies, a trend that has been and is currently taking place in the post-secondary education industry in the country, we may face increasing levels of competition in the markets in which we operate. If we are unable to maintain our competitive position or otherwise respond to competitive pressures effectively, we may lose our market share, our profits may decrease, and we may be adversely affected.

#### We may not be able to update, improve or offer the content of our existing educational platform on a cost-effective basis.
Our educational platform is designed to offer a complete suite of turnkey curriculum solutions intended to prepare the primary and secondary education students at our partner schools to sit the ENEM (which is equivalent to the Gaokao in China and loosely comparable to the SAT in the United States), for entry into post-secondary educational institutions and which is also used by the MEC and the market to evaluate Brazilian public and private schools. To differentiate ourselves and remain competitive, we must continually update our content and develop new educational solutions, including through the adoption of new technological tools to deliver our content. Updates to our current content and the development of new educational solutions may not be readily accepted by our partner schools, their students or by the market. Also, we may not be able to introduce new educational solutions at the same pace as our competitors or at the pace required by the market or by certain regulatory measures that establishes guidelines to educational content in Brazil, such as National Education Guidelines Law (*Lei de Diretrizes e Bases da Educação Nacional*), or LDB, the National Common Core Curriculum (*Base Nacional Comum Curricular), or BNCC,* or the National Curriculum Guidelines (*Diretrizes Nacionais Curriculares*), or DCN. If we do not adequately modify our educational platform in response to market demand, whether due to financial restrictions, technological changes or otherwise, our ability to attract new schools and retain partner schools may be impaired and we may be materially adversely affected.

***Our business depends on the continued success of our brands, and if we fail to maintain and enhance the recognition of our brands, we may face difficulty increasing our network of partner schools, and our reputation and operating results may be harmed.***

We believe that market awareness of our brands, SAS, SAE Digital, SPE, COC, International School, Escola da Inteligência, among others, has contributed significantly to the success of our business. Maintaining and enhancing our brands is critical to our efforts to increase our network of partner schools, which is in turn critical to our business. We rely heavily on the efforts of our sales force and our marketing channels, including online advertising, search engine marketing, social media, and word-of-mouth. Failure to maintain and enhance the recognition of our brands could have a material and adverse effect on our business, operating results, and financial condition. We have devoted significant resources to our brand promotion efforts and the training of our sales force in recent years, but we cannot assure you that these efforts will be successful.

[**Table of Contents**](#TOC)

Our ability to attract new partner schools depends not only on investment in our brand, our marketing efforts and the success of our sales force, but also on the perceived value of our services versus competing alternatives among our client base. In addition, a failure by our clients to distinguish between our brands and the different content that they provide may result in a reduction in sales volume and revenue, margins, or market share of one of our brands at the expense of the others. If our marketing initiatives are not successful or become less effective, if we are unable to further enhance our brand recognition, or if we incur excessive marketing and promotion expenses, or if our brand image is negatively impacted by any negative publicity, we may not be able to attract new partner schools successfully or efficiently, and our business and results of operations may be materially and adversely affected.

In addition, if any partner school using our educational platforms engages in unlawful activities or uses our educational platforms in an unauthorized manner, the general public may associate such school's behavior with our brand, generating negative publicity that may adversely affect our reputation.

***If we continue to grow, we may not be able to appropriately manage the expansion of our business and staff, the increased complexity of our software and platforms, or grow in our addressable market.***

We are currently experiencing a period of significant expansion and may face, as a result, certain expansion-related issues, such as cash flow management, corporate culture, IT integration and internal controls, among others. These issues and the significant amount of time spent on addressing them may result in the diversion of our management's attention from other business issues and opportunities. In addition, we believe that our corporate culture and values are critical to our success, and we have invested a significant amount of time and resources building them. If we fail to preserve our corporate culture and values, our ability to recruit, retain and develop personnel and to effectively implement our strategic plans may be harmed.

We must constantly update our software and platform, enhance and improve our billing and transaction and other business systems, and add and train new software designers and engineers, as well as other personnel to accommodate the increased use of our platform and the new solutions and features we regularly introduce. This process is time intensive and expensive and may lead to higher costs in the future. Furthermore, we may need to enter into relationships with various strategic partners, other online service providers and other third parties necessary to our business. The increased complexity of managing multiple commercial relationships could lead to execution problems that can affect current and future revenues, and operating margins.

We cannot assure you that our current and planned platform and systems, procedures and controls, personnel and third-party relationships will be adequate to support our future operations. In addition, our continuous expansion places a significant strain on management and on our operational and financial resources, which strain is expected to continue. Our failure to manage growth effectively could seriously harm our business, results of operations and financial condition.

***An increase in delays and/or defaults in the payment of amounts owed to us by partner schools may adversely affect our income and cash flow.***

We depend on the full and timely payment of the amounts owed to us by partner schools. Our partner schools may face financial difficulties, and in certain cases, insolvency or bankruptcy. An increase in payment delinquency or default by partner schools may have a material adverse effect on our cash flows and our business, including our ability to meet our obligations, and in certain circumstances, we may decide to terminate our contracts with such partner schools, increasing our attrition rates. Moreover, these risks may be aggravated during the COVID-19 pandemic, including due to an economic crisis resulting from the COVID-19 pandemic, which may, for example, increase the levels of delinquency or default. Our allowance for doubtful accounts expenses as a percentage of our net revenue was 0.1%, 2.2% and 3.5% for the years ended December 31, 2022, 2021 and 2020, respectively.

***Our business is subject to seasonal fluctuations, which may cause our operating results to fluctuate from quarter-to-quarter and adversely impact our working capital and liquidity throughout the year, negatively affecting our business, financial condition and results of operations.***

Our revenues and operating results normally fluctuate as a result of seasonal variations in our business, principally due to the number of months in a fiscal quarter that our partner schools are fully operational and serving students. Our main deliveries are shipped to partner schools in the last quarter of each year (typically in November and December), and in the first quarter of each

[**Table of Contents**](#TOC)

subsequent year (typically in February and March). Furthermore, the materials we deliver in the fourth quarter are used by our partner schools for the following school year, and as such, our fourth quarter results reflect the growth in the number of our students from one school year to another, leading to generally higher revenues in our fourth quarter compared to the preceding quarters in each fiscal year. Consequently, in aggregate, the seasonality of our revenues has generally produced higher revenues in the first and fourth quarters of our fiscal year. In addition, we bill partner schools and collect the sales we charge them in the first half of each academic collections year, generally resulting in a higher cash position in the first half of each fiscal year relative to the second half of each fiscal year.

A significant portion of our expenses are also seasonal. Due to the nature of our business cycle, we require significant working capital, typically in September or October of each year, to cover costs related to production and accumulation of inventory, selling and marketing expenses, and delivery of our teaching materials at the end of each fiscal year in preparation for the beginning of each school year. Therefore, such operating expenses are generally incurred in the period between September and December of each year.

Accordingly, we expect quarterly fluctuations in our revenues and operating results to continue. These fluctuations could result in volatility and adversely affect our liquidity and cash flows. As our business grows, these seasonal fluctuations may become more pronounced. As a result, we believe that sequential quarterly comparisons of our financial results may not provide an accurate assessment of our financial position.

Our working capital needs have increased and may continue to increase for the near future. We have historically relied on our cash flow generation to satisfy our working capital needs. We expect our working capital needs to increase as our business expands. If at some point in time we do not have sufficient working capital, we may not be able to pursue our growth strategy, respond to competitive pressures or fund key strategic initiatives, which may harm our business, financial condition and results of operations.

***The sales cycle of our business may cause our operating results to fluctuate from quarter-to-quarter and adversely impact our working capital and liquidity from year to year, adversely affecting our business, financial condition, and results of operations.***

Our platform has evolved into a complex solution. The adoption of our platform by partner schools requires us to first build a high level of trust and confidence in our solutions, which can only be achieved by demonstrating a proven track record of success and quality, while constantly monitoring client satisfaction and feedback.

We have a lead time (which we define as the period from the moment of first contact to the execution of a contract) for the acquisition of new partner schools, and we typically enter into contracts with new partner schools within one year from the moment of first contact, which requires a series of interactions and constant contact, including dedicated sessions for experimentation with our platform and testing, events aimed at target partner schools, product journeys and guided visits to our business units, and industry fair exhibits. Accordingly, we expect quarterly fluctuations in our cash flows.

These fluctuations could result in annual volatility and adversely affect our liquidity. As our business grows or if our business stops growing and we lose clients, these fluctuations may become more pronounced.

#### We do not currently control some of our equity investments, which could adversely affect our ability to commercialize our products.
We acquire interests in third parties for the expansion, development or commercialization of our products. As of the date of this annual report, we have a 10.88% interest in Bewater Ventures I GA FIP – Multiestratégia, or Bewater, a fund managed by Paraty Capital, which used the proceeds from our investment to subsequently make a minority investment in Grupo A, a company that provides educational solutions for higher education. Additionally, we have a 23.43% interest in Tera Treinamentos Profissionais S.A., a company that offers tech-related educational services, such as UX design, full stack development and data analytics, among others, for the B2B and B2C markets. We do not currently have a controlling interest in these companies and any disagreements or disputes with these or other companies where we have a minority interest could adversely affect our ability to develop and commercialize our products and in turn, our financial condition, and results of operations. The failure to continue any investment arrangement or to resolve disagreements with current or future companies where we have a minority interest could materially and adversely affect our

[**Table of Contents**](#TOC)

ability to transact the business that is the subject of such investment arrangement, which would in turn negatively affect our financial condition and results of operations.

***We may pursue strategic acquisitions or investments. The failure of an acquisition or investment to produce the anticipated results, or the inability to integrate an acquired company fully, could harm our business.***

We are currently evaluating possible acquisition opportunities, and we may from time to time submit non-binding proposals or acquire or invest in complementary companies or businesses, as part of our strategy to expand our operations, including through acquisitions or investments that may be material in size and/or of strategic relevance. The success of an acquisition or investment will depend on our ability to make accurate assumptions regarding the valuation, operations, growth potential, integration and other factors related to that business. We cannot assure you that our acquisitions or investments will produce the results that we expect at the time we enter, or complete, a given transaction. Furthermore, acquisitions may result in difficulties integrating the acquired companies, and may result in the diversion of our capital and our management's attention from other business issues and opportunities. We may not be able to successfully integrate the operations that we acquire, including their personnel, financial systems, distribution or operating procedures. If we fail to integrate acquisitions successfully, our business could suffer. In addition, the expense of integrating any acquired business and their results of operations may harm our operating results.

In order to conduct certain acquisitions, investments or divestments, we may also require pre-merger control approvals from the Brazilian Administrative Council for Economic Defense (*Conselho Administrativo de Defesa Econômica*), or CADE, or other regulatory authorities.

We may require additional funds to continue our expansion strategy. If we are unable to obtain adequate financing to complete any potential acquisition and implement our expansion plans, our growth strategy may be adversely affected.

For further information about our acquisitions and investments, see "Item 4. Information on the Company—A. History and development of the company—Acquisitions and Investments."

#### If we lose key personnel our business, financial condition and results of operations may be adversely affected.
We are dependent upon the ability and experience of a number of our key personnel who have substantial experience with our operations. Many of our key personnel have worked for us for a significant amount of time or were recruited by us specifically due to their industry experience. It is possible that the loss of the services of one or a combination of our senior executives, certain members of our board of directors or key managers, including Ari de Sá Cavalcante Neto, our chief executive officer, director and founder, and Oto Brasil de Sá Cavalcante, our chairman, could have a material adverse effect on our business, financial condition, and results of operations. We currently do not carry any key man insurance.

#### The ability to attract, recruit, retain and develop qualified employees is critical to our success and growth.
In order for us to successfully compete and grow and increase the number of partner schools, we must attract, recruit, retain and develop the necessary personnel who can provide the required expertise across the entire spectrum of our high-quality educational content needs, including with respect to sales and marketing. While a number of our key personnel have substantial experience with our operations, we must also develop succession plans capable of maintaining continuity in the midst of the inevitable unpredictability of human capital. However, the market for qualified personnel is competitive, and we may not succeed in recruiting additional personnel or may fail to effectively replace current personnel who depart with qualified or effective successors. We must continue to hire additional personnel to execute our strategic plans. Our effort to retain and develop personnel may also result in significant additional expenses, which could adversely affect our profitability. We cannot assure that qualified employees will continue to be employed or that we will be able to attract and retain qualified personnel in the future. In particular, we may not achieve anticipated revenue growth from expanding our sales and marketing teams if we are unable to attract, develop and retain qualified sales and marketing personnel in the future.

Failure to retain or attract key personnel could have a material adverse effect on our business, financial condition and results of operations.

[**Table of Contents**](#TOC)

#### Any increase in the attrition rates of students in our partner schools may adversely affect our results of operations.
We believe that the attrition rates at our partner schools are primarily related to the personal motivation and financial situation of their current and potential students, as well as to socioeconomic conditions in Brazil. Significant changes in projected student attrition rates and/or failure to re-enroll may affect the enrollment numbers of our partner schools, as well as their ability to recruit and enroll new students, each of which may have a material adverse effect on our projected revenues and our results of operations.

#### We may face restrictions and penalties under the Brazilian Consumer Protection Code and the Brazilian Antitrust Law in the future.
Brazil has a series of strict consumer protection laws, referred to collectively as the Consumer Protection Code (*Código de Defesa do Consumidor*). These laws apply to all companies in Brazil that supply products or services to Brazilian consumers. They include protection against misleading and deceptive advertising, protection against coercive or unfair business practices and protection in the formation and interpretation of contracts, usually in the form of civil liabilities and administrative penalties for violations. Although we are a business-to-business-to-consumer, or B2B2C, business, some consumers may allege that we are directly liable for any problems in our solution and try to assess us based upon the Consumer Protection Code.

These penalties are often levied by the Brazilian Consumer Protection Agencies (*Fundação de Proteção e Defesa do Consumidor*, or PROCONs), which oversee consumer issues on a district-by-district basis. Companies that operate across Brazil may face penalties from multiple PROCONs, as well as from the National Secretariat for Consumers (*Secretaria Nacional do Consumidor*, or SENACON). Companies may settle claims made by consumers via PROCONs by paying compensation for violations directly to consumers and through a mechanism that allows them to adjust their conduct, called a conduct adjustment agreement (*Termo de Ajustamento de Conduta*, or TAC).

Brazilian public prosecutors may also commence investigations of alleged violations of consumer rights and require companies to enter into TACs. Companies that violate TACs face potential enforcement proceedings and other potential penalties such as fines, as set forth in the relevant TAC. Brazilian public prosecutors may also file public civil actions against companies who violate consumer rights or competition rules, seeking strict adherence to the consumer protection laws and compensation for any damages to consumers.

As a company operating in Brazil, we are also subject to Brazilian antitrust laws and regulations, which establishes penalties for practices that are deemed violations of the economic order. In certain cases, we may be investigated or sanctioned by the CADE, to the extent our business practices are deemed to (i) limit, restrain or in any way harm free competition or free initiative; (ii) control the relevant market of goods or services; (iii) arbitrarily increase profits, and (iv) abusively exercise a dominant position.

***Our success depends on our ability to monitor and adapt to technological changes in the education sector and maintain a technological infrastructure that works adequately and without interruption.***

Information technology is an essential factor of our growth given that we deliver content through an integrated online educational platform. Our information technology systems and tools may become obsolete or insufficient, or we may have difficulties in following and adapting to technological changes in the education sector. Moreover, our competitors may introduce better products or platforms. Our success depends on our ability to efficiently improve our platform while developing and introducing new features that are accepted by schools (including our partner schools) and their students.

Additionally, a failure to upgrade our technology, features, content, security infrastructure, network infrastructure, or other infrastructure associated with our platform could harm our business. Adverse consequences could include unanticipated disruptions, slower response times, bugs, degradation in levels of customer support, impaired quality of users' experiences of our educational platform and delays in reporting accurate financial information.

In addition, we face risks associated with unauthorized access to our systems, including by hackers and due to failures of our electronic security measures. These unauthorized entries into our systems can result in the theft of proprietary or sensitive information or cause interruptions in the operation of our systems. As a result, we may be forced to incur considerable expenses to protect our systems from electronic security breaches and to mitigate our exposure to technological problems and interruptions.

[**Table of Contents**](#TOC)

Our business depends on our information technology infrastructure functioning properly and without interruptions. Several problems regarding our information technology structure, such as viruses, hackers, system interruptions and other technical difficulties may have a material adverse effect on us and our business.

Regarding the aforementioned risks we implemented some of the best security practices currently used in the market. We used the NIST Cyber Security framework that provides practices, controls and technologies that enable our company to recover, identify, protect, detect, and respond to cybernetic risks.

Some of the best practices that we have today are: (i) assets controls and monitoring; (ii) malware infection risk monitoring; (iii) we developed an access model, and we can manage this access with automatized tools; (iv) event monitoring of our main technologies using a SIEM solution. This solution permits that we correlate events and identify possible threats or security incidents; (v) implemented a scheduled routine with infrastructure intrusion tests; (vi) monthly vulnerability analysis in our systems and fixes if required; (vii) created awareness programs for our employees; (viii) we are currently implementing other recommendations to increase our maturity level, some of them are: (a) implement security in our internal network infrastructure; (b) implement a risk management process and (c) build a disaster recovery plan to all critical environments.

***We derive the majority of our revenues from the contract fees per student that we generate from the sales of our educational content to our partner schools. Any disruption in our relationship with our partner schools may materially adversely affect us.***

Our network of partner schools to which we make available our B2B2C Core Curriculum and Supplemental Content Solutions comprises 8,071 partner schools as of March 30, 2023. Our net revenue was R$1,775.4 million and R$1,232.1 million for the years ended December 31, 2022, and 2021. We typically enter into contracts with our partner schools for one-year terms for our Supplemental solutions and three to five-year terms for our Core solutions, which contemplate penalties ranging between 20% and 100% of the remaining total value of the contract in the event of termination. In addition, we also rely in part on existing partner school referrals to attract new partner schools. Accordingly, maintaining a good relationship with our schools, developing new relationships and expanding our network of partner schools are essential to the success of our business. We may also not be able to renew our contracts with our partner schools, including because of new leadership in our partner schools deciding to discontinue the use or expansion of our educational platform in their curriculum. Any deterioration in our relationship with our partner schools, and any early termination of, or a failure to renew, our contracts with our partner schools may harm our image, impair our ability to pursue our growth strategy, and materially adversely affect our business, our operating and financial results and our cash flows.

To support our growth and to help us retain our clients, we have a dedicated sales support team that provides pedagogical assistance to partner schools and helps them train students and teachers to fully engage with the features of our platform, in order to maximize their results from using our solutions. Our pedagogical support team also makes visits and performs field work for these purposes, building rapport and strengthening our ties with our partner schools. If we fail to provide efficient and effective customer support, or to maintain our customer support standards as our business grows, our ability to maintain and grow our operations may be harmed and we may need to hire additional support personnel, which could harm our results of operations.

***Increases in the price of certain inputs used to produce our printed educational materials and increases in the fees of our third-party printer providers may materially affect us.***

Increases in the price of the inputs used for editing and publishing the materials related to our Core Curriculum and Supplemental Content Solutions particularly the price of paper, the cost of printing services and publishing, as well as increases in the fees of our third-party printer providers, which produce our printed educational materials, could adversely affect our results, if we are not able to fully pass these cost increases onto our partner schools.

Paper and postage prices are difficult to predict and control. Paper is a commodity, and its price may be impacted by fluctuations in foreign exchange rates and commodities prices and can be subject to significant volatility. Our third-party printer providers have adjusted their fees to account for changes in prevailing market prices of their inputs, especially paper. Though we have historically been able to realize favorable pricing through volume discounts, particularly as a result of our significant recent growth, no assurance can be provided that we will be able to continue to realize favorable printing and publishing pricing. We cannot predict with certainty

[**Table of Contents**](#TOC)

the magnitude of future price changes for paper, postage, and printing and publishing in general. Further, we may not be able to pass such increases on to our partner schools.

#### We may not be able to pass on increases in our costs by adjusting the contract fees we charge our partner schools.
Our primary source of income is the payments we receive from our partner schools in connection with the contract fees per student that we charge them to use our Core Curriculum and Supplemental Content Solutions. For the year ended December 31, 2022, operation, sales, and corporate personnel expenses represented 28.5% and third-party services expenses represented 5.2% of our total costs and expenses for the period. Personnel costs are adjusted periodically using indices that reflect changes in inflation levels. Personnel costs are also adjusted annually because of customary annual employee salary adjustments in line with inflation. If we are not able to transfer any increases in our costs to partner schools by increasing the contract fees per student that we charge them, our operating results may be adversely affected.

***Any changes in tax law, tax reforms or review of the tax treatment of our activities, including the loss or reduction in tax benefits on the sale of books (including digital content) may materially adversely affect us.***

We currently benefit from tax Law No. 10,865/04, as amended by Law No. 11,033/04, which establishes a zero-rate for the social integration program tax (*Programa de Integração Social*, or PIS) and the social contribution on revenues tax (*Contribuição para o Financiamento da Seguridade Social*, or COFINS) on the sale of books. The sale of the books is also exempt by the Brazilian constitution from the Brazilian municipal services tax (*Imposto Sobre Serviços*, or ISS) and from the Brazilian tax on the circulation of goods, interstate and intercity transportation and communication services (*Imposto sobre Operações relativas à Circulação de Mercadorias e sobre Prestações de Serviços de Transporte Interestadual e Intermunicipal e de Comunicação*, or ICMS). If the Brazilian government or any Brazilian state, municipality or tax authority decides to change, revoke or review the current tax treatment of our activities, or cancel or reduce the tax benefit applied on the sale of goods, including digital books and e-readers, and/or challenge it, and we are unable to pass any cost increase onto our partner schools, our results may be materially adversely affected.

As of the date of this annual report, there are several bills relating to tax reforms that are under review by the Brazilian Congress. The proposed tax reforms involve a comprehensive overhaul of the consumer tax system. One bill proposes to (i) extinguish three federal taxes, the federal tax on manufactured products (*Imposto sobre Produtos Industrializados*, or IPI), PIS and COFINS; (ii) create and apply ICMS at the state level and ISS at the municipal level; and (iii) create a new tax on transactions for goods and services (*Imposto sobre Operações com Bens e Serviços*, or IBS). Another bill proposes to create a social contribution tax on transactions for goods and services (*Contribuição Social sobre Operações com Bens e Serviços*, or CBS) at a 12% rate, which would substitute PIS and COFINS and revoke our zero-rate tax benefits for PIS and COFINS on the sale of books. Additional bills may be proposed in the context of such wide-ranging tax reforms. Moreover, there are recent discussions concerning the potential imposition of new taxes, including new taxes on compulsory loans, taxes on large fortunes and a contribution on financial transactions, as well as discussions to repeal the income tax exemption applicable to the distribution of dividends.

The extent to which the tax reform will impact our financial results and operations will depend on future developments, which are still uncertain and cannot be predicted due to the early stage of the process. Based on future developments of the tax reform, it is possible that we may, in the future, be required to take actions or steps in relation to our business that could have a disruptive or a material and adverse effect on our business. A tax reform or any change in the laws and regulations that affect the taxes or tax incentives applicable to us may directly or indirectly adversely impact our business and results of operations.

***If we are unable to maintain consistent educational quality throughout our partner schools' network, including the education materials we provide to our partner schools, we may be adversely affected.***

The quality of our academic curricula is a key element of the quality of the Core Curriculum and Supplemental Content Solutions we provide. We cannot assure that we will be able to develop academic curricula for our Core Curriculum and Supplemental Content Solutions with the same levels of excellence as existing curricula and meeting the requirements of the LDB, BNCC and DCN, to which we are currently subject, or meeting the requirements of our partner schools. Deficiencies in the quality of academic curricula for our educational platform and changes in the requirements of the LDB, BNCC and DCN may have a material adverse effect on our

[**Table of Contents**](#TOC)

business. To this date, we have implemented the mandatory requirements, but some modifications must be implemented in the following years to comply with LDB, BNCC and DCN requirements.

In addition, we are required to adapt our education materials to the requirements of the new National Curriculum Guidelines *(Diretrizes Nacionais Curriculares* or DCN) for high school, which are known as the "New High School" (*Novo Ensino Médio*). If we fail to adapt our education materials to the New High School education framework, our business and results of operations could be adversely affected.

Furthermore, our partner schools and their students are regularly evaluated and graded by the State and Municipal Education Secretaries and MEC. If our partner schools' campuses, programs or students receive lower scores from the MEC than in previous years in any of their evaluations, including the IDEB and the ENEM, or if there is a decline in our partner schools students' acceptance rates at prestigious higher education institutions post-secondary schools, we may be adversely affected by perceptions of decreased educational quality of our educational platform, which may negatively affect our reputation and, consequently, our results of operations and financial condition.

***We may become subject to various laws and regulations applicable to educational platform providers, and failure to meet such future laws and regulations could harm our business.***

Currently, we may follow the requirements of the LDB, BNCC and DCN to elaborate our educational content, and we are not regulated by the MEC nor are we subject to any government regulations that are imposed by National Education Board (*Conselho Nacional de Educação*), or the CNE, or by the Primary and Secondary Education Board (*Câmara de Educação Básica*), or CEB. Should we become subject to the supervision and regulation of the MEC or any other authority or any government laws and regulations imposed by the CNE or the CEB or any other authority, we may be required to meet certain legal and regulatory requirements that may be imposed on our operations, including, but not limited to, MEC accreditation or re-accreditation requirements for our educational platform, which may adversely affect us. We may be adversely affected by changes in the laws and regulations applicable to educational platform providers, particularly by changes that impose accreditation and re-accreditation requirements on educational platforms and impose certain academic requirements for educational platform courses and curricula. In addition, we may be materially adversely affected if we are unable to obtain these authorizations and accreditations in a timely manner or if we cannot introduce new features to our educational platform as quickly as our competitors.

#### The quality of the pedagogical content we deliver to our clients is significantly dependent upon the quality of our editors, publishers and purchased content.
The educational materials we provide are a combination of content developed by our internal production team and content purchased from certain publishers in our market. Our editorial team is responsible for producing our materials, working in conjunction with our EdTech team to implement additional features and technology delivery. Our content production process requires significant coordination among different teams as well as qualified personnel with appropriate skill sets to ensure the quality of our pedagogical content is maintained. We may not be able to retain, recruit or train qualified employees or obtain pedagogical content that meets our standards. Delays in the delivery of content purchased from authors may have a severe impact on our annual content creation schedule. Additionally, a shortage of qualified editors, employees, publishers or suitable purchased content or a decrease in the quality of produced or purchased content, whether actual or perceived, or a significant increase in the cost to engage or retain qualified personnel or acquire content, would have a material adverse effect on our business, financial condition, and results of operations.

***We utilize third-party logistics service providers for the shipping of all our collections of printed teaching materials. The successful delivery of our materials to our clients depends upon effective execution by our logistics team and such service providers. Any material failure to execute properly for any reason, including damage or disruption to any service providers' facilities, would have an adverse effect on our business, financial condition, and results of operations.***

The delivery of printed books to schools is a seasonal activity, with a cycle beginning with the creation and revision of content generally from April to July, the purchase of printing services from August to October, and delivery from November to January. We have expanded our operations rapidly since our inception. As our size increases, so does the size and complexity of our logistics operation.

[**Table of Contents**](#TOC)

There is a high volume of deliveries in November and December, requiring significant involvement in inventory/demand management and relationship and planning alongside the printers. In an industry where one of the most valued indicators by the schools is the timely delivery of printed materials, failure to meet deadlines, inadequate logistical planning, disruptions in distribution centers, deficient inventory management, and failure to meet client requirements may damage our reputation, increase returns of our materials or cause inventory losses and negatively impact our gross margins, results of operations and business.

Our inventory for our printed teaching materials is substantially located in warehouse facilities leased and operated by us and then delivered by a third-party shipping company that handles shipping of all physical learning materials. If our logistics service providers fail to meet their obligations to deliver teaching materials to partner schools in a timely manner, or if a material number of such deliveries are incomplete or contain assembly errors, our business and results of operations could be adversely affected. Furthermore, a natural disaster, fire, power interruption, work stoppage or other unanticipated catastrophic event, especially during the period from August through October when we are awaiting receipt of most of the curriculum materials for the school year and have not yet shipped such materials to partner schools, could significantly disrupt our ability to deliver our products and operate our business. If any of our material inventory items, warehouse facilities or distribution centers were to experience any significant damage, we would be unable to meet our contractual obligations and our business would suffer.

#### Failure to protect or enforce our intellectual property and other proprietary rights could adversely affect our business and financial condition and results of operations.
We rely and expect to continue to rely on a combination of trademark, copyright, patent and trade secret protection laws, as well as confidentiality and license agreements with our employees, consultants and third parties with whom we have relationships to protect our intellectual property and proprietary rights.

As of December 31, 2022, we relied on trademark, patent, copyright, and other intellectual property laws to establish and protect its products and services and owns several intellectual property assets in Brazil and abroad, including 617 trademarks registrations in Brazil (563 of which have been granted and 54 of which are under review but that we are entitled to use), 1 industrial design registration in process, and 9 software registrations. In relation to international assets, we have 12 trademarks registrations: 2 in Argentina, 2 in Bolivia, 3 in Chile, 1 in Ecuador, 2 in Paraguay and 1 in Uruguay.

Our intellectual property rights in Brazil extend to 115 registered domain names and content that do not require certification or registration in order to be protected. In addition, we own several registered copyrights, most notably copyrights for text, images, edition, reformulation and book updates, among others.

Any dismissal of our trademarks' applications may impact our business. Third parties may challenge any patents, copyrights, trademarks and other intellectual property and proprietary rights owned or held by us. Third parties may knowingly or unknowingly infringe, misappropriate, or otherwise violate our patents, copyrights, trademarks and other proprietary rights and we may not be able to prevent infringement, misappropriation, or other violation without substantial expense to us.

Furthermore, we cannot guarantee that:

● our intellectual property and proprietary rights will provide competitive advantages to us;

● our competitors or others will not design around our intellectual property or proprietary rights;

● our ability to assert our intellectual property or proprietary rights against potential competitors or to settle current or future disputes will not be limited by our agreements with third parties;

● our intellectual property and proprietary rights will be enforced in jurisdictions where competition may be intense or where legal protection may be weak;

● any of the patents, trademarks, copyrights, trade secrets or other intellectual property or proprietary rights that we presently employ in our business will not lapse or be invalidated, circumvented, challenged or abandoned; or

[**Table of Contents**](#TOC)

● we will not lose the ability to assert our intellectual property or proprietary rights against or to license our intellectual property or proprietary rights to others and collect royalties or other payments.

If we pursue litigation to assert our intellectual property or proprietary rights, an adverse decision in any of these legal actions could limit our ability to assert our intellectual property or proprietary rights, limit the value of our intellectual property or proprietary rights or otherwise negatively impact our business, financial condition and results of operations. If the protection of our intellectual property and proprietary rights is inadequate to prevent use or misappropriation by third parties, the value of our brand and other intangible assets may be diminished, competitors may be able to mimic our service and methods of operations more effectively, the perception of our business and service to customers and potential customers may become confused in the marketplace and our ability to attract customers may be adversely affected.

***We may in the future be subject to intellectual property claims, which are costly to defend and could harm our business, financial condition, and operating results.***

Because of the large number of authors that participate in our publications, from time to time, third parties may allege in the future that we or our business infringes, misappropriates, or otherwise violates their intellectual property or proprietary rights, including with respect to our publications. Many companies, including various "non-practicing entities" or "patent trolls," are devoting significant resources to developing or acquiring patents that could potentially affect many aspects of our business. There are numerous patents that broadly claim means and methods of conducting business on the internet. We have not exhaustively searched patents related to our technology. In addition, the publishing industry has been, and we expect in the future will continue to be, the target of counterfeiting and piracy. We may implement measures to protect against these potential liabilities that could require us to spend substantial resources. Any costs incurred because of liability or asserted liability relating to sales of unauthorized or counterfeit educational materials could harm our business, reputation and financial condition.

Third parties may initiate litigation against us without warning. Others may send us letters or other communications that make allegations without initiating litigation. We have in the past and may in the future receive such communications, which we assess on a case-by-case basis. We may elect not to respond to the communication if we believe it is without merit or we may attempt to resolve disputes out-of-court by electing to pay royalties or other fees for licenses. If we are forced to defend ourselves against intellectual property claims, whether they are with or without merit or are determined in our favor, we may face costly litigation, diversion of technical and management personnel, inability to use our current website or inability to market our service or merchandise our products. As a result of a dispute, we may have to develop non-infringing technology, including partially or fully revise any publication that infringes intellectual property rights, enter into licensing agreements, adjust our merchandising or marketing activities or take other action to resolve the claims. These actions, if required, may be unavailable on terms acceptable to us or may be costly or unavailable. If we are unable to obtain sufficient rights or develop non-infringing intellectual property or otherwise alter our business practices, as appropriate, on a timely basis, our reputation or brand, our business and our competitive position may be affected adversely, and we may be subject to an injunction or be required to pay or incur substantial damages and/or fees and/or royalties.

Certain of our services are provided using proprietary software and our software is mainly developed by our employees, who specifically assign to us their copyrights over the software in their employment agreements. Additionally, the applicable law establishes that employers shall have full title over rights relating to software developed by their employees. Nonetheless, we could be subject to lawsuits by former employees claiming ownership of proprietary software that were not specifically assigned to us in their respective employment agreements. As a result, we may be required to obtain licenses of such software, incurring costs relating to payments of royalties and/or damages and we may be forced to cease the use of such software. If we are unable to use certain of our proprietary software, this could have a material adverse effect on our business, financial condition and results of operations.

In addition, we use open-source software in connection with certain of our products and services. Companies that incorporate open-source software into their products have, from time to time, faced claims challenging the ownership of open-source software and/or compliance with open-source license terms. As a result, we could be subject to suits by parties claiming ownership of what we believe to be open-source software or noncompliance with open-source licensing terms. Some open-source software licenses require users who distribute or use open-source software as part of their software to publicly disclose all or part of the source code to such software and/or make available any derivative works of the open-source code on unfavorable terms or at no cost. Any requirement to

[**Table of Contents**](#TOC)

disclose our proprietary source code or pay damages for breach of contract could have a material adverse effect on our business, financial condition, and results of operations.

***We may be subject to risks related to non-compliance with the Brazilian Data Protection Law and may be adversely affected by the application of penalties, including pecuniary sanctions. Additionally, failure to comply with data privacy regulations could result in reputational damage to our brands an adversely affect our business, financial and condition and results of operations.***

On August 14, 2018, Law No. 13,709 of August 14, 2018, was enacted, as amended, or the Brazilian Personal Data Protection Law ("LGPD"), which came fully into effect in September 2020 and brought major changes to the personal data protection system in Brazil.

The LGPD establishes a new legal framework to be observed by individuals and legal entities, detailing rules for the collection, production, reception, classification, use, access, reproduction, transmission, distribution, processing, filing, storage, elimination, evaluation or information control, modification, communication, transfer, dissemination, or extraction of personal data and provides, among others, for the rights of data subjects, the legal bases applicable to the processing of personal data, the requirements for obtaining consent and others obligations and penalties. The National Data Protection Authority (ANPD) is the body of the federal public administration responsible for ensuring the protection of personal data and for implementing and monitoring compliance with the LGPD in Brazil.

If we do not comply with the LGPD, we could be subject to one, or a combination of, administrative sanctions applicable by the National Data Protection Authority, which came into force on August 1, 2021. Sanctions include (1) warnings, with the imposition of a deadline for the adoption of corrective measures; (2) fines, up to a maximum amount of 2% of company's or group's turnover in Brazil limited to R$50.0 million per violation; (3) disclosure of the violation; (4) the restriction of access to or deletion of the personal data to which the violation relates; (5) in case of repetition of the violation, temporary suspension of the database or of data processing activities, partial or complete prohibition of processing activities.

Additionally, any perceived or actual unauthorized disclosure of personally identifiable information, whether through breach of our network by an unauthorized party, employee theft, misuse, or error or otherwise, could harm our reputation, impair our ability to attract and retain our customers, or subject us to claims or litigation arising from damages suffered by individuals.

Failure to protect the personal data processed by us, as well as failure to comply with the applicable legislation, may result in high fines, disclosure of the incident to the market, cancellation of existing contracts, temporary block and/or deletion of the personal data from our database, without eliminating the possibility of civil and criminal sanctions, which may adversely affect our reputation, financial condition and results of operations. In addition, we could incur significant costs in complying with relevant laws and regulations regarding the unauthorized disclosure of personal information, which may be affected by any changes to data privacy legislation at both the federal and state levels. See "Item 4. Information on the Company—B. Business Overview—Regulatory Overview—Data Protection."

#### Cybersecurity incidents, including attacks on the infrastructure necessary to maintain our IT systems, may result in financial losses and damage to our reputation.<sup>1</sup>
Despite system redundancy and the implementation of security measures, our systems are vulnerable to damages from any number of sources, including energy blackouts, natural disasters, terrorism, war, telecommunication failures and cybersecurity attacks, such as malware, ransomware, or unauthorized access. Across our business we hold large volumes of personally identifiable information including that of employees, schools, customers, students and parents and legal guardians. Individuals may try to gain unauthorized access to our data to misappropriate such information for potentially fraudulent purposes, and our security measures may fail to prevent such unauthorized access. Cybersecurity incidents may result in the misappropriation of our information and/or customer information or in ineffective time on its servers or operations, which may affect us materially and adversely.

[**Table of Contents**](#TOC)

The growing frequency of attempted cybersecurity attacks may lead to increased costs to protect the company and respond to any events, including additional personnel, consultants and protection technologies. For example, we have improved the monitoring of our infrastructure and systems and are seeking to implement the best practices regarding the development of IT systems. Any compromise of our security could result in a violation of applicable privacy and other laws, unauthorized access to information of ours and others, significant legal and financial exposure, damage to our reputation, loss or misuse of the information and a loss of confidence in our security measures, which could harm our business. Additionally, remediation costs for security events may not be covered by our insurance. In addition, if we were unable to prove that our systems are properly designed to detect an intrusion, we could be subject to severe penalties and loss of existing or future business. Any losses of intellectual property, trade secrets or other sensitive business information or the interruption of its operations could adversely affect our financial results. We have been monitoring our systems and made several security tests to identify our potential weakness in advance and implement the applicable security measures.

#### We are susceptible to illegal or improper uses of our educational platform, which could expose us to additional liability and harm our business.
Our educational platform is susceptible to unauthorized use, copyright violations and unauthorized copying and distribution (whether by students, schools or otherwise), theft, employee fraud, and other similar breaches and violations. These occurrences may potentially harm our business and consequently negatively impact our results of operations.

As a result, we may be required to employ a significant amount of resources to combat such occurrences and identify those responsible.

#### Unfavorable decisions in our legal, arbitration or administrative proceedings may adversely affect us.
We are, and may be in the future, party to legal, arbitration and administrative investigations, inspections and proceedings arising in the ordinary course of our business or from extraordinary corporate, tax or regulatory events, involving our controlling shareholders, subsidiaries, controlled or affiliated entities, suppliers, commercial practices, students, faculty members, as well as environmental, competition, government agencies and tax authorities, particularly with respect to civil, tax, antitrust and labor claims. We cannot guarantee that the results of these proceedings will be favorable to us or that we have made sufficient provisions for liabilities that may arise because of these or other proceedings. Even if we adequately address issues raised by any inspection conducted by an agency or successfully defend our case in an administrative proceeding or court action, we may have to set aside significant financial and management resources to settle issues raised by such proceedings or to those lawsuits or claims.

Therefore, failures in our governance, risk management and compliance programs and other internal policies, as well as adverse decisions in material legal, arbitrational or administrative proceedings related to the applicable laws and other legal provisions, in Brazil or overseas, even if such proceedings are without merit, may adversely affect our reputation, businesses, financial conditions, results of operations and the price of our Class A common shares, and may subject our administrators to criminal penalties.

***We depend on dividend distributions by our subsidiaries, and we may be adversely affected if the performance of our subsidiaries is not positive or if Brazil imposes legal restrictions on dividend distributions by subsidiaries.***

We control several subsidiary companies in Brazil that carry out our business activities. Our ability to comply with our financial obligations and to pay future dividends, if any, to our shareholders depends on our ability to receive distributions from the companies we control, which in turn depends on the cash flow and profits of those companies. There is no guarantee that the cash flow and profits of our controlled companies will be sufficient for us to comply with our financial obligations and pay future dividends or interest on shareholders' equity, if any, to our shareholders, or that the Brazilian federal government will not impose legal restrictions or tax payments on dividend distributions by our subsidiaries.

[**Table of Contents**](#TOC)

***We and our subsidiaries may be held directly or indirectly responsible for labor claims resulting from the actions of third parties, including independent contractors and service providers.***

To meet the needs of our partner schools and offer greater comfort and quality in all areas and aspects of our activities, we depend on service providers and suppliers for a variety of services. We may be adversely affected if these third-party service providers and suppliers do not meet their obligations under Brazilian labor laws. According to Brazilian law we may be liable to the employees of these service providers and suppliers for labor obligations of these service providers and suppliers and may also be fined by the relevant authorities. If we are held liable for such claims, we may be adversely affected.

***We operate in markets that are dependent on Information Technology, or IT, systems, and technological change. Failure to maintain and support customer facing services, systems, and platforms, including addressing quality issues and execution on time of new products and enhancements, could negatively impact our revenues and reputation.***

We use complex IT systems and products to support our businesses activities, including customer-facing systems, back-office processing, and infrastructure. We face several technological risks associated with online product service delivery, information technology security (including virus and cyber-attacks), e-commerce and Enterprise Resource Planning, or ERP, system upgrades. Our plans and procedures to reduce risks of attacks on our system by unauthorized parties may not be successful. Thus, our businesses could be adversely affected if our systems and infrastructure experience a failure or interruption in the event of future attacks on our system by unauthorized parties.

***We rely upon a third-party data center service provider to host certain aspects of our platform and content and any disruption to, or interference with, our use of such services, could impair our ability to deliver our platform, resulting in customer dissatisfaction, damaging our reputation, and harming our business.***

We utilize data center hosting facilities from a global third-party service provider to make certain content available in our platform. Our operations depend, in part, on our provider's ability to protect its facilities against damage or interruption from natural disasters, power or telecommunications failures, criminal acts and similar events. The occurrence of spikes in user volume, traffic, natural disasters, acts of terrorism, vandalism or sabotage, or a decision to close a facility without adequate notice, or other unanticipated problems at our provider's facilities could result in lengthy interruptions in the availability of our platform, which would adversely affect our business.

***Failure to prevent or detect a malicious cyber-attack on our systems and databases could result in a misappropriation of confidential information or access to highly sensitive information.***

Cyber-attacks are becoming more sophisticated and pervasive. Across our business we hold large volumes of personally identifiable information including that of employees, schools, customers, students and parents and legal guardians. Individuals may try to gain unauthorized access to our data to misappropriate such information for potentially fraudulent purposes, and our security measures may fail to prevent such unauthorized access. A breach could result in a devastating impact on our reputation, financial condition, or student experience, as well as sanctions provided for by the LGPD. In addition, if we were unable to prove that our systems are properly designed to detect an intrusion, we could be subject to severe penalties and loss of existing or future business. We have been monitoring our systems and made several security tests to identify our potential weakness in advance and implement the applicable security measures.

[**Table of Contents**](#TOC)

***A material weakness in our internal control over financial reporting may be identified, and if we fail to establish and maintain proper and effective internal controls over financial reporting, our results of operations and our ability to operate our business may be harmed.***

In connection with the audit of our consolidated financial statements, we and our independent registered public accounting firm may identify material weaknesses, which is a deficiency, or combination of control deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim consolidated financial statements will not be prevented or detected on a timely basis. Our management has assessed the effectiveness of our internal control over financial reporting and has concluded that the Company maintained effective internal controls as of December 31, 2022.

We are subject to the Sarbanes-Oxley Act, which requires, among other things, that we establish and maintain effective internal controls over financial reporting and disclosure controls and procedures. Testing of our internal controls may reveal deficiencies that are deemed to be material weaknesses or significant deficiencies and render our internal controls over financial reporting ineffective. If we are not able to comply with these requirements in a timely manner, or if we or our management identifies material weaknesses or significant deficiencies in our internal controls over financial reporting that are deemed to be material weaknesses, the market price of our Class A common shares may decline and we may be subject to investigations or sanctions by the SEC, the Financial Industry Regulatory Authority, Inc., or FINRA, or other regulatory authorities.

The effectiveness of such internal controls over financial reporting as of December 31, 2022 was audited by Ernst & Young Auditores Independentes S.S. Ltda., or EY, the independent registered public accounting firm that also audited our consolidated financial statements as of and for the year then ended. EY has issued an unqualified report on our internal control over financial reporting, which is included elsewhere in this annual report.

***Climate change can create transition risks, physical risks and other risks that could adversely affect us.***

Climate risk is a transversal risk that can be an aggravating factor for the types of traditional risks that we manage in the ordinary course of business, including, without limitation, the risks described in this "Risk Factors" section. Based on the classifications used by the Taskforce on Climate-Related Financial Disclosures, we consider that there are two primary sources of climate change-related financial risks: physical and transition.

Physical risks resulting from climate change can be event-driven (acute) or long-term shifts (chronic) in climate patterns:

● Acute physical risks include increased severity of extreme weather events, such as drought, hurricanes, or floods;

● Chronic physical risks include changes in precipitation patterns and extreme variability in weather patterns, rising mean temperatures, chronic heat waves or rising sea levels;

The main physical risks that can impact us are acute physical risks that can disrupt our supply chain and delay the delivery of our printed educational materials to partner schools located in regions impacted by extreme weather events.

Transition risks refer to actions to address mitigation and adaptation requirements related to climate change, and they can fall into various categories such as market and technology changes:

● Market risk may manifest through shifts in supply and demand for certain commodities, products, and services, as climate-related risks and opportunities are increasingly considered. Changes in the price and availability of paper could disrupt paper supply, which would impact our printed educational materials production cycle and consequently, our business.

● Technology risk arises from improvements or innovations to support the transition to a lower-carbon, energy-efficient economic system that can have a significant impact on companies to the extent that new technology displaces old systems and disrupts some parts of the existing economic system. One of our strategies to minimize our carbon footprint

[**Table of Contents**](#TOC)

is to reduce the number of physical pages we print as part our printed educational materials by making those educational materials available to students digitally on our online platform.

Policy actions generally fall into two categories: those that attempt to constrain actions that contribute to the adverse effects of climate change and those that seek to promote adaptation to climate change. The risk associated with, and the financial impact of policy changes depend on the nature and timing of the policy change.

Our partner schools may be adversely affected by increased regulatory requirements going forward as a result of the increasing importance of environmental matters, which may indirectly affect our business. This and other changes in regulations in Brazil and international markets may expose us to increased compliance costs, limit our ability to pursue certain business opportunities and provide certain products and services, each of which could adversely affect our business, financial condition, and results of operations.

#### Certain Factors Relating to Brazil
***The Brazilian federal government has exercised, and continues to exercise, significant influence over the Brazilian economy. This involvement as well as Brazil's political, regulatory, legal and economic conditions could harm us and the price of our Class A common shares.***

The Brazilian federal government frequently exercises significant influence over the Brazilian economy and occasionally makes significant changes in policy and regulations. The Brazilian government's actions to control inflation and other policies and regulations have often involved, among other measures, increases or decreases in interest rates, changes in fiscal policies, wage and price controls, foreign exchange rate controls, blocking access to bank accounts, currency devaluations, capital controls and import and export restrictions. We have no control over and cannot predict what measures or policies the Brazilian government may take in the future, and how these can impact us and our business. We and the market price of our securities may be harmed by changes in Brazilian government policies, as well as general economic factors, including, without limitation:

● growth or downturn of the Brazilian economy;

● interest rates and monetary policies;

● exchange rates and currency fluctuations;

● inflation;

● liquidity of the domestic capital and lending markets;

● import and export controls;

● exchange controls and restrictions on remittances abroad and payments of dividends;

● modifications to laws and regulations according to political, social and economic interests;

● fiscal policy and changes in tax laws and related interpretations by tax authorities;

● economic, political and social instability, including general strikes and mass demonstrations;

● the regulatory framework governing the educational industry;

● labor and social security regulations;

● energy and water shortages and rationing;

[**Table of Contents**](#TOC)

● commodity prices, including prices of paper and ink;

● public health, including as a result of epidemics and pandemics, such as the COVID-19 pandemic;

● changes in demographics, in particular declining birth rates, which will result in a decrease in the number of enrolled students in primary and secondary education in the future; and

● other political, diplomatic, social and economic developments in or affecting Brazil.

Uncertainty over whether the Brazilian federal government will implement reforms or changes in policy or regulation affecting these or other factors in the future may affect economic performance and contribute to economic uncertainty in Brazil, which may have an adverse effect on our activities and consequently our results of operations, and may also adversely affect the trading price of our Class A common shares. In addition, the new federal administration that took office in January 2023 could result in an increase in government interference in the economy, which could negatively impact us and our results of operations.

Further, Brazil's political environment has historically influenced, and continues to influence, the performance of the country's economy. The recent economic instability in Brazil has contributed to a decline in market confidence in the Brazilian economy as well as to a deteriorating political environment. See "—The ongoing economic uncertainty and political instability in Brazil, including as a result of ongoing corruption investigations, may harm us and the price of our Class A common shares."

As has been true in the past, the current political and economic environment in Brazil has and is continuing to affect the confidence of investors and the general public, which has historically resulted in economic deceleration and heightened volatility in the securities offered by companies with significant operations in Brazil, which may adversely affect us and our Class A common shares.

See "Item 5. Operating and Financial Review and Prospects—Brazilian macroeconomic environment" for further information.

#### The ongoing economic uncertainty and political instability in Brazil may harm us and the price of our Class A common shares.
Brazil's political environment has historically influenced, and continues to influence, the performance of the country's economy. Political crises have affected and continue to affect the confidence of investors and the general public, which have historically resulted in economic deceleration and heightened volatility in the securities offered by companies with significant operations in Brazil.

The recent economic instability in Brazil has contributed to a decline in market confidence in the Brazilian economy as well as to a deteriorating political environment. In addition, various ongoing investigations into allegations of money laundering and corruption being conducted by the Brazilian Federal Prosecutor's Office, including the largest such investigation, known as "*Operação Lava Jato*," have negatively impacted the Brazilian economy and political environment. The potential outcome of these investigations is uncertain, but they have already had an adverse impact on the image and reputation of the implicated companies, and on the general market perception of the Brazilian economy.

In March 2021, a Brazilian Federal Supreme Court ruling issued by Justice Edson Fachin annulled the decisions that had convicted former President Luiz Inácio Lula da Silva. As a result of this ruling, President Luiz Inácio Lula da Silva recovered his political rights and ran for office in the 2022 presidential elections in Brazil, with a first round on October 2, 2022. A second round between candidates was necessary as none of the candidates obtained more than 50% of the valid votes. The second round was held on October 30, 2022. President Luiz Inácio Lula da Silva was elected with 50.90% of the votes. Since the results of the presidential election were announced, certain groups formed by extreme supporters of the defeated candidate have been organizing public demonstrations and protests against the electronic ballot boxes and the existence of an alleged conspiracy against their candidate. On January 8, 2023, thousands of supporters of the defeated candidate and now former president invaded Brazil's Congress and presidential offices, among other government buildings in Brasília, Federal District. Any potential threat to the democratic system or ballot counting may result in the deterioration of the political environment and, consequently, affect the confidence of investors and the general public.

In addition, on April 14, 2021, a Parliamentary Committee of Inquiry (*Comissão Parlamentar de Inquérito*), or "CPI," was established to investigate actions and omissions by the Brazilian federal government in facing the pandemic and collapse of health in the State of Amazonas at the beginning of the year and the misuse of funds to combat the effects of COVID-19 in Brazil. With the support and expedition of a precautionary measure by the Brazilian Supreme Court justice, Luís Roberto Barroso, the necessary measures were taken for the creation and installation of the CPI. The CPI investigated, among other things, alleged failures to impose lockdowns or promote social distancing, the successive removals of health ministers to manage the pandemic, and the promotion of unproven drugs in treating COVID-19. Upon completion of the congressional investigation, a final report was approved on October 26, 2021, recommending that the former president be indicted for nine crimes related to his handling of the COVID-19 pandemic, including crimes against humanity. The congressional report could lead to criminal charges or trigger an impeachment proceeding.

Moreover, concerns regarding any potential interventionist stances in the future may have direct or indirect impacts on the market. Any resulting consequences of these investigations could have material adverse effects on the political and economic environment in Brazil, as well as on businesses operating in Brazil, including ours. The potential outcome of these and other investigations is uncertain, but they have already had a negative impact on the general perception of the market on the Brazilian economy and have affected and may continue to adversely affect our business, our financial condition and our operating results, as well as the trading price of our Class A common shares. We cannot predict whether the ongoing investigations will result in further political and economic instability, or if new allegations against government officials and/or executives of private companies will arise in the future or will result in additional investigations.

A failure by the Brazilian government to implement necessary reforms may result in diminished confidence in the Brazilian government's budgetary condition and fiscal stance, which could result in downgrades of Brazil's sovereign foreign credit rating by credit rating agencies, negatively impact Brazil's economy, and lead to further depreciation of the real and an increase in inflation and interest rates, which could adversely affect our business, financial condition and results of operations.

Any of the above factors may create additional political uncertainty, which could harm the Brazilian economy and, consequently, our business and the price of our Class A common shares.

***Inflation and certain measures by the Brazilian government to curb inflation have historically harmed the Brazilian economy and Brazilian capital markets, and high levels of inflation in the future would harm our business and the price of our Class A common shares.***

In the past, Brazil has experienced extremely high rates of inflation. Inflation and some of the measures taken by the Brazilian government to curb inflation have had significant negative effects on the Brazilian economy generally. Inflation, policies adopted to curb inflationary pressures and uncertainties regarding possible future governmental intervention have contributed to economic uncertainty and heightened volatility in the Brazilian capital markets.

[**Table of Contents**](#TOC)

According to the National Consumer Price Index *(Índice Nacional de Preços ao Consumidor Amplo)*, or IPCA, which is published by the IBGE, Brazilian inflation rates were 5.8%, 10.1% and 4.5% in 2022, 2021 and 2020, respectively. Brazil may experience high levels of inflation in the future and inflationary pressures may lead to the Brazilian government's intervening in the economy and introducing policies that could harm our business and the price of our Class A common shares. In the past, the Brazilian government's interventions included the maintenance of a restrictive monetary policy with high interest rates that restricted credit availability and reduced economic growth, causing volatility in interest rates. For example, the official interest rate in Brazil oscillated from 7.00% as of December 31, 2017, to 2.00% as of December 31, 2020, as established by the Monetary Policy Committee *(Comitê de Política Monetária do Banco Central do Brasil*), or COPOM. Beginning in March 2021, COPOM began increasing Brazil's official interest rate, reaching 13.75% as of December 31, 2022. As of the date of this annual report, Brazil's official interest rate was 13.75%. Conversely, more lenient government and Central Bank policies and interest rate decreases have triggered and may continue to trigger increases in inflation, and, consequently, growth volatility and the need for sudden and significant interest rate increases, which could negatively affect us and increase our indebtedness. In 2022, higher inflation directly impacted all our cost lines, in particular paper and printing costs, logistics and transportation costs, and the travelling expenses of our sales teams.

#### Exchange rate instability may have adverse effects on the Brazilian economy, us and the price of our Class A common shares.
The Brazilian currency has been historically volatile and has been devalued frequently over the past three decades. Throughout this period, the Brazilian government has implemented various economic plans and used various exchange rate policies, including sudden devaluations, periodic mini-devaluations (during which the frequency of adjustments has ranged from daily to monthly), exchange controls, dual exchange rate markets and a floating exchange rate system.

Although long-term depreciation of the real is generally linked to the rate of inflation in Brazil, depreciation of the *real* occurring over shorter periods of time has resulted in significant variations in the exchange rate between the *real*, the U.S. dollar and other currencies. The *real*/U.S. dollar exchange rate reported by the Central Bank was R$5.197 per U.S.$1.00 on December 31, 2020, which reflected a 28.9% depreciation in the *real* against the U.S. dollar during 2020. The *real*/U.S. dollar exchange rate reported by the Central Bank was R$5.581 per U.S.$1.00 on December 31, 2021, which reflected a 7.4% depreciation in the real against the U.S. dollar during 2021. The *real*/U.S. dollar exchange rate reported by the Central Bank was R$5.218 per U.S.$1.00 on December 31, 2022, which reflected a 6.5% appreciation in the *real* against the U.S. dollar during 2022. There can be no assurance that the real will not again depreciate against the U.S. dollar or other currencies in the future.

A devaluation of the *real* relative to the U.S. dollar could create inflationary pressures in Brazil and cause the Brazilian government to, among other measures, increase interest rates. Any depreciation of the *real* may generally restrict access to the international capital markets. It would also reduce the U.S. dollar value of our results of operations. Restrictive macroeconomic policies could reduce the stability of the Brazilian economy and harm our results of operations and profitability. In addition, domestic and international reactions to restrictive economic policies could have a negative impact on the Brazilian economy. These policies and any reactions to them may harm us by curtailing access to foreign financial markets and prompting further government intervention. A devaluation of the *real* relative to the U.S. dollar may also, as in the context of the current economic slowdown, decrease consumer spending, increase deflationary pressures, and reduce economic growth.

On the other hand, an appreciation of the *real* relative to the U.S. dollar and other foreign currencies may deteriorate the Brazilian foreign exchange current accounts. We and certain of our suppliers purchase goods and services from countries outside Brazil, and thus changes in the value of the U.S. dollar compared to other currencies may affect the costs of goods and services that we purchase. Depending on the circumstances, either devaluation or appreciation of the *real* relative to the U.S. dollar and other foreign currencies could restrict the growth of the Brazilian economy, as well as our business, results of operations and profitability.

#### Infrastructure and workforce deficiency in Brazil may impact economic growth and have a material adverse effect on us.
Our performance depends on the overall health and growth of the Brazilian economy. Brazilian GDP performance has fluctuated over the past few years, with a contraction of 3.3% in 2020, a growth of 5.0% in 2021 and a growth of 2.9% in 2022. Growth has been structurally limited by inadequate infrastructure, including potential energy shortages and deficient transportation, logistics and telecommunication sectors, general strikes, the lack of a qualified labor force, and the lack of private and public investments in these areas, which limit productivity and efficiency. Any of these factors could lead to labor market volatility and generally impact income, purchasing power and consumption levels, which could limit growth and ultimately have a material adverse effect on us.

***Developments and the perceptions of risks in other countries, including other emerging markets, the United States and Europe, may harm the Brazilian economy and the price of our Class A common shares.***

The market for securities offered by companies with significant operations in Brazil is influenced by economic and market conditions in Brazil and, to varying degrees, market conditions in other Latin American and emerging markets, as well as the United States, Europe and other countries. To the extent the conditions of the global markets or economy deteriorate, the business of companies with significant operations in Brazil may be harmed. The weakness in the global economy has been marked by, among other adverse factors, lower levels of consumer and corporate confidence, decreased business investment and consumer spending, increased unemployment, reduced income and asset values in many areas, reduction of China's growth rate, currency volatility and limited availability of credit and access to capital. Developments or economic conditions in other emerging market countries have at times significantly affected the availability of credit to companies with significant operations in Brazil and resulted in considerable outflows of funds from Brazil, decreasing the amount of foreign investments in Brazil.

Crises and political instability in other emerging market countries, the United States, Europe or other countries could decrease investor demand for securities offered by companies with significant operations in Brazil, such as our Class A common shares. Investors' sentiment in one country may cause capital markets in other countries to fluctuate, affecting the value of our Class A common shares, even if indirectly. The economic, political, and social instability in the United States, the trade war between the United States and China, crises in Europe and other countries, the consequences of United Kingdom's exit from the European Union, and global tensions, as well as economic or political crises in Latin America or other emerging markets including as a result of the COVID-19 pandemic or the ongoing war between Russia and Ukraine, may significantly affect the perception of the risks inherent in investment in Brazil.

Additionally, the U.S. president has considerable influence, which may materially and adversely affect global economy and political stability. We cannot ensure that the U.S. government will adopt policies designed to promote macroeconomic stability, fiscal discipline, as well as domestic and foreign investment, which may materially and adversely impact the trading price of securities of Brazilian issuers, including our Class A common shares. Growing economic uncertainty and news of a potentially recessive economy in the United States may also create uncertainty in the Brazilian economy.

These developments, as well as potential crises and forms of political instability arising therefrom or any other as of yet unforeseen development, may adversely affect the United States and global economies and capital markets, which may, in turn, materially adversely affect the trading price of our Class A common shares.

#### Any further downgrading of Brazil's credit rating could reduce the trading price of our Class A common shares.
Given the current significance of our Brazil operations to our results of operations, we may be harmed by investors' perceptions of risks related to Brazil's sovereign debt credit rating. Rating agencies regularly evaluate Brazil and its sovereign credit ratings, which are based on several factors including macroeconomic trends, fiscal and budgetary conditions, indebtedness metrics and the perspective of changes in any of these factors.

[**Table of Contents**](#TOC)

The rating agencies began to review Brazil's sovereign credit rating in September 2015. Subsequently, the three major rating agencies downgraded Brazil's investment-grade status:

● In 2015, Standard & Poor's initially downgraded Brazil's credit rating from BBB-negative to BB-positive and subsequently downgraded it again from BB-positive to BB, maintaining its negative outlook, citing a worse credit situation since the first downgrade. On January 11, 2018, Standard & Poor's further downgraded Brazil's credit rating from BB to BB-stable, which was reaffirmed on June 15, 2022.

● In December 2015, Moody's placed Brazil's Baa3's issue and bond ratings under review for downgrade and subsequently downgraded the issue and bond ratings to below investment grade, at Ba2 with a negative outlook, citing the prospect of a further deterioration in Brazil's debt indicators, taking into account the low growth environment and the challenging political scenario. On April 12, 2022, Moody's maintained Brazil's credit rating at Ba2-stable.

● In 2016, Fitch downgraded Brazil's sovereign credit rating to BB-positive with a negative outlook, citing the rapid expansion of the country's budget deficit and the worse-than-expected recession. In February 2018, Fitch downgraded Brazil's sovereign credit rating again to BB-negative, citing, among other factors, fiscal deficits, the increasing burden of public debt and an inability to implement reforms that would structurally improve Brazil's public finances. On July 14, 2022, while reaffirming Brazil's credit rating at BB-negative, Fitch changed its outlook on Brazil's credit rating to a positive outlook.

Brazil's sovereign credit rating is currently rated below investment grade by the three main credit rating agencies. Consequently, the prices of securities offered by companies with significant operations in Brazil have been negatively affected.

The full consequences of a credit rating downgrade are inherently uncertain, as they depend upon numerous dynamic, complex, and inter-related factors and assumptions, including market conditions at the time of any downgrade. A prolongation or worsening of the current Brazilian recession and continued political uncertainty, among other factors, could lead to further ratings downgrades. We cannot assure you that the rating agencies will maintain their current ratings or outlooks, and such changes could increase our funding costs and adversely affect our results of operations. Any further downgrade of Brazil's sovereign credit ratings could heighten investors' perception of risk and, as a result, cause the trading price of our Class A common shares to decline.

***The war between Russia and Ukraine may have a material adverse effect on our business, financial condition, liquidity and results of operations.***

Global markets are experiencing volatility and disruption following the escalation of geopolitical tensions and the start of the war between Russia and Ukraine. In February 2022, Russia launched a full-scale military invasion of Ukraine. Although the length and impact of the ongoing military conflict is unpredictable, the conflict in Ukraine has created and could lead to further market disruptions, including significant volatility in commodity prices, credit and capital markets. The war between Russia and Ukraine has led to sanctions and other penalties being levied by the United States, European Union and other countries mainly against Russia, including an agreement to remove certain Russian financial institutions from the Society for Worldwide Interbank Financial Telecommunication payment system. Additional potential sanctions and penalties have also been proposed and/or threatened. The war is expected to have further global economic consequences, including but not limited to the possibility of severely diminished liquidity and credit availability, declines in consumer confidence, scarcity in certain raw materials and products, declines in economic growth, increases in inflation rates and uncertainty about economic and political stability. In addition, there is a risk that Russia and other countries supporting Russia in this conflict may launch cyberattacks against the United States and its allies and other countries, their governments and businesses, including the infrastructure in such countries. Any of the foregoing consequences, including those we cannot yet predict, may have a material adverse effect on our business, financial condition, liquidity and results of operations.

#### Certain Factors Relating to Our Class A Common Shares
***The Founding Shareholders, our largest group of shareholders, own 100% of our outstanding Class B common shares, which represents 90.7% of the voting power of our issued share capital, and will control all matters requiring shareholder approval. This concentration of ownership and voting power limits your ability to influence corporate matters.***

As of December 31, 2022, Oto Brasil de Sá Cavalcante, Margarida Maria Porto Soares de Sá Cavalcante, Ari de Sá Cavalcante Neto, Mariana Magalhães de Sá Cavalcante, Patrícia Soares de Sá Cavalcante, Paula Soares de Sá Cavalcante and Luciana Soares de Sá Cavalcante Moraes, or the Founding Shareholders, control our company and do not hold any of our Class A common shares (except for Ari de Sá Cavalcante Neto, who held as of December 31, 2022, 1.4% of the Class A common shares), but beneficially own 49.0% of our issued share capital through their beneficial ownership of all of our outstanding Class B common shares, and consequently, 90.7% of the combined voting power of our issued share capital. Our Class B common shares are entitled to 10 votes per share and our Class A common shares, which are publicly traded, are entitled to one vote per share. Our 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. As a result, the Founding Shareholders will control the outcome of all decisions at our shareholders' meetings and will be able to elect a majority of the members of our board of directors. In addition, so long as they are appointed and are serving as our directors, they will also be able to influence our actions in areas such as business strategy, financing, distributions, acquisitions and dispositions of assets or businesses. For example, the Founding Shareholders, in their capacity as directors, may influence decisions to make acquisitions that increase the amount of our indebtedness or outstanding Class A common shares, sell revenue-generating assets or inhibit change of control transactions that benefit other shareholders. The Founding Shareholders' decisions on these matters may be contrary to your expectations or preferences, and they may take actions that could be contrary to your interests. They can prevent any other shareholders, including you, from blocking these actions. For further information regarding shareholdings in our company, see "Item 7. Major Shareholders and Related Party Transactions—A. Major shareholders."

As long as the Founding Shareholders continue to beneficially own a sufficient number of Class B common shares, even if they beneficially own significantly less than 50% of our outstanding share capital, acting together, they will be able to effectively control our decisions. For example, if our Class B common shares amounted to 15% of our outstanding common shares, beneficial owners of our Class B common shares (consisting of the Founding Shareholders), would collectively control 63.8% of the voting power of our outstanding common shares. If the Founding Shareholders sell or transfer any of their Class B common shares, they will generally convert automatically into Class A common shares, subject to limited exceptions, such as transfers to affiliates, to trustees for the holder or its affiliates and certain transfers to U.S. tax exempt organizations. The fact that any Class B common shares convert into Class A common shares if the Founding Shareholders sell or transfer them means that the Founding Shareholders will in many situations continue to control a majority of the combined voting power of our outstanding share capital, due to the voting rights of any Class B common shares that they retain. However, if our Class B common shares at any time represent less than 10% of the total number of shares in the capital of the Company outstanding, the Class B common shares then outstanding will automatically convert into Class A common shares. For a description of the dual class structure, see "Item 10. Additional Information—B. Memorandum and articles of association."

***There can be no assurance that any definitive offer will be made with respect to the Going Private Transaction, that any agreement will be executed or that this or any other transaction will be approved or consummated.***

On November 30, 2022, we received a proposal from General Atlantic and Dragoneer with respect to the Going Private Transaction. For additional information, see "Item 4. Information on the Company—A. History and Development of the Company—Proposed Going Private Transaction." There can be no assurance that any definitive offer will be made, that any agreement will be executed or that any proposed going private transaction will be approved or consummated. These uncertainties may increase the volatility of the market price of our Class A common shares and have a material adverse effect on our Class A common shares.

[**Table of Contents**](#TOC)

The proposed going private transaction, whether or not pursued or consummated, presents a risk of diverting our management's focus, our employees' attention and resources from other strategic opportunities and from operational matters. In addition, if we sign any definitive agreement with General Atlantic and Dragoneer, we may be subject to various restrictions under those agreements on the conduct of our business prior to the completion of the transaction, which may delay or prevent us from undertaking business opportunities that may arise pending completion of the transaction. Also, any development of the Going Private Transaction, such as entering into or termination of any definitive agreement, may increase volatility of the trading price of our securities. Potential uncertainty involving the proposed going private transaction may adversely affect our business and the market price of our Class A common shares.

***Our Articles of Association contain anti-takeover provisions that may discourage a third-party from acquiring us and adversely affect the rights of holders of our Class A common shares.***

Our Articles of Association contain certain provisions that could limit the ability of others to acquire our control, including a provision that grants authority to our board of directors to establish and issue from time to time one or more series of preferred shares without action by our shareholders and to determine, with respect to any series of preferred shares, the terms and rights of that series. These provisions could have the effect of depriving our shareholders of the opportunity to sell their shares at a premium over the prevailing market price by discouraging third parties from seeking to obtain our control in a tender offer or similar transactions.

***If securities or industry analysts do not publish research, or publish inaccurate or unfavorable research, about our business, the price of our Class A common shares and our trading volume could decline.***

The trading market for our Class A common shares depends in part on the research and reports that securities or industry analysts publish about us or our business. If one or more of the analysts who cover us downgrade our Class A common shares or publish inaccurate or unfavorable research about our business, the price of our Class A common shares would likely decline. If one or more of these analysts cease coverage of our company or fail to publish reports on us regularly, demand for our Class A common shares could decrease, which might cause the price of our Class A common shares and trading volume to decline.

#### We do not anticipate paying any cash dividends in the foreseeable future.
We currently intend to retain our future earnings, if any, for the foreseeable future, to fund the operation of our business and future growth. We do not intend to pay any dividends to holders of our Class A common shares. As a result, capital appreciation in the price of our Class A common shares, if any, will be your only source of gain on an investment in our Class A common shares.

[**Table of Contents**](#TOC)

***Our dual class capital structure means our shares are not included in certain indices. We cannot predict the impact this may have on our share price.***

In 2017, FTSE Russell, S&P Dow Jones and MSCI announced changes to their eligibility criteria for inclusion of shares of public companies on certain indices to exclude companies with multiple classes of shares of common stock, such as ours, from being added to such indices. FTSE Russell announced plans to require new constituents of its indices to have at least five percent of their voting rights in the hands of public stockholders, whereas S&P Dow Jones announced that companies with multiple share classes, such as ours, will not be eligible for inclusion in the S&P 500, S&P MidCap 400 and S&P SmallCap 600, which together make up the S&P Composite 1500. MSCI also opened public consultations on their treatment of no-vote and multi-class structures and temporarily barred new multi-class listings from its ACWI Investable Market Index and U.S. Investable Market 2500 Index. However, in October 2018, MSCI announced its decision to include equity securities "with unequal voting structures" in its indices and to launch a new index that specifically includes voting rights in tis eligibility criteria. We cannot assure you that other stock indices will not take a similar approach to FTSE Russell, S&P Dow Jones and MSCI in the future. Under the announced policies, our dual class capital structure is not eligible for inclusion in any of these indices and, as a result, mutual funds, exchange-traded funds and other investment vehicles that attempt to passively track these indices will not invest in our stock. It continues to be unclear what effect, if any, these policies will have on the valuations of publicly traded companies excluded from the indices, but in certain situations they may depress these valuations compared to those of other similar companies that are included. Exclusion from indices could make our Class A common shares less attractive to investors and, as a result, the market price of our Class A common shares could be adversely affected.

***The dual class structure of our common stock has the effect of concentrating voting control with the Founding Shareholders; this will limit or preclude your ability to influence corporate matters.***

Each Class A common share entitles its holder to one vote per share, and each Class B common share will entitle its holder to ten votes per share, so long as the total number of the issued and outstanding Class B common shares is at least 10% of the total number of shares outstanding. Due to the ten-to-one voting ratio between our Class B and Class A common shares, the beneficial owners of our Class B common shares (composed of the Founding Shareholders) collectively will continue to control a majority of the combined voting power of our common shares and therefore be able to control all matters submitted to our shareholders requiring the approval of an ordinary resolution so long as the total number of the issued and outstanding Class B common shares is at least 10% of the total number of shares outstanding.

In addition, our Articles of Association provide that at any time when there are Class A common shares in issue, additional Class B common shares may only be issued pursuant to (1) a share split, subdivision of shares or similar transaction or where a dividend or other distribution is paid by the issue of shares or rights to acquire shares or following capitalization of profits, (2) a merger, consolidation, or other business combination involving the issuance of Class B common shares as full or partial consideration, or (3) an issuance of Class A common shares, whereby holders of the Class B common shares are entitled to purchase a number of Class B common shares that would allow them to maintain their proportional ownership interests in Arco (following an offer by us to each holder of Class B common shares to issue to such holder, upon the same economic terms and at the same price, such number of Class B common shares as would ensure that such holder may maintain a proportional ownership interest in Arco pursuant to our Articles of Association).

Future transfers by holders of Class B common shares will generally result in those shares converting to Class A common shares, subject to limited exceptions, such as certain transfers effected to permitted transferees or for estate planning or charitable purposes. The conversion of Class B common shares to Class A common shares will have the effect, over time, of increasing the relative voting power of those holders of Class B common shares who retain their shares in the long term.

In light of the above provisions relating to the issuance of additional Class B common shares, the fact that future transfers by holders of Class B common shares will generally result in those shares converting to Class A common shares, subject to limited exceptions as provided in the Articles of Association; as well as the ten-to-one voting ratio of our Class B common shares and Class A common shares, holders of our Class B common shares will in many situations continue to maintain control of all matters requiring shareholder approval. This concentrated control will limit or preclude your ability to influence corporate matters for the foreseeable future. For a description of our dual class structure, see "Item 10. Additional Information—B. Memorandum and articles of association—Voting Rights."

***We are a Cayman Islands exempted company with limited liability. The rights of our shareholders, including with respect to fiduciary duties and corporate opportunities, may be different from the rights of shareholders governed by the laws of U.S. jurisdictions.***

We are a Cayman Islands exempted company with limited liability. Our corporate affairs are governed by our Articles of Association and by the laws of the Cayman Islands. The rights of shareholders and the responsibilities of members of our board of directors may be different from the rights of shareholders and responsibilities of directors in companies governed by the laws of U.S. jurisdictions. As a matter of Cayman Islands law, directors of a Cayman Islands company owe fiduciary duties to the company and separately a duty of care, diligence and skill to the company. Under Cayman Islands law, directors and officers owe the following fiduciary duties: (i) duty to act in good faith in what the director or officer believes to be in the best interests of the company as a whole; (ii) duty to exercise powers for the purposes for which those powers were conferred and not for a collateral purpose; (iii) directors should not improperly fetter the exercise of future discretion; (iv) duty to exercise powers fairly as between different sections of shareholders; (v) duty to exercise independent judgment; and (vi) duty not to put themselves in a position in which there is a conflict between their duty to the company and their personal interests. Our Articles of Association have varied this last obligation by providing that a director must disclose the nature and extent of his or her interest in any contract or arrangement, and following such disclosure and subject to any separate requirement under applicable law or the listing rules of the Nasdaq, and unless disqualified by the chairman of the relevant meeting, such director may vote in respect of any transaction or arrangement in which he or she is interested and may be counted in the quorum at the meeting. Conversely, under Delaware corporate law, a director has a fiduciary duty to the corporation and its stockholders (made up of two components) and the director's duties prohibits self-dealing by a director and mandates that the best interest of the corporation and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by the shareholders generally. See "Item. 16G Corporate Governance—Principal Differences between Cayman Islands and U.S. Corporate Law."

#### As a foreign private issuer, we will have different disclosure and other requirements than U.S. domestic registrants.
As a foreign private issuer, we may be subject to different disclosure and other requirements than domestic U.S. registrants. For example, as a foreign private issuer, in the United States, we are not subject to the same disclosure requirements as a domestic U.S. registrant under the Exchange Act, including the requirements to prepare and issue quarterly reports on Form 10-Q or to file current reports on Form 8-K upon the occurrence of specified significant events, the proxy rules applicable to domestic U.S. registrants under Section 14 of the Exchange Act or the insider reporting and short-swing profit rules applicable to domestic U.S. registrants under Section 16 of the Exchange Act. In addition, we intend to rely on exemptions from certain U.S. rules which will permit us to follow Cayman Islands legal requirements rather than certain of the requirements that are applicable to U.S. domestic registrants.

We will follow Cayman Islands laws and regulations that are applicable to Cayman Islands companies. However, Cayman Islands laws and regulations applicable to Cayman Islands companies do not contain any provisions comparable to the U.S. proxy rules, the U.S. rules relating to the filing of reports on Form 10-Q or 8-K or the U.S. rules relating to liability for insiders who profit from trades made in a short period of time, as referred to above.

Furthermore, foreign private issuers are required to file their annual report on Form 20-F within 120 days after the end of each fiscal year, while U.S. domestic issuers that are accelerated filers are required to file their annual report on Form 10-K within 75 days after the end of each fiscal year. Foreign private issuers are also exempt from Regulation Fair Disclosure, aimed at preventing issuers from making selective disclosures of material information, although we will be subject to Cayman Islands laws and regulations having substantially the same effect as Regulation Fair Disclosure. As a result of the above, even though we are required to file reports on Form 6-K disclosing the limited information which we have made or are required to make public pursuant to Cayman Islands law, or are required to distribute to shareholders generally, and that is material to us, you may not receive information of the same type or amount that is required to be disclosed to shareholders of a U.S. company.

***As a foreign private issuer, we are permitted to, and we will, rely on exemptions from certain Nasdaq corporate governance standards applicable to U.S. issuers, including the requirement that a majority of an issuer's directors consist of independent directors. This may afford less protection to holders of our Class A common shares.***

Section 5605 of the Nasdaq equity rules requires listed companies to have, among other things, a majority of their board members be independent, and to have independent director oversight of executive compensation, nomination of directors and corporate governance matters. As a foreign private issuer, however, we are permitted to and follow home country practice in lieu of the above requirements. See "Item 16G Corporate Governance—Principal Differences between Cayman Islands and U.S. Corporate Law."

***We may lose our foreign private issuer status which would then require us to comply with the Exchange Act's domestic reporting regime and cause us to incur significant legal, accounting and other expenses.***

To maintain our current status as a foreign private issuer, either (a) more than 50% of our Class A common shares must be either directly or indirectly owned of record by non-residents of the United States or (b)(i) a majority of our executive officers or directors may not be U.S. citizens or residents, (ii) more than 50% of our assets cannot be located in the United States and (iii) our business must be administered principally outside the United States. If we lose this status, we would be required to comply with the Exchange Act reporting and other requirements applicable to U.S. domestic issuers, which are more detailed and extensive than the requirements for foreign private issuers. We may also be required to make changes in our corporate governance practices in accordance with various SEC and Nasdaq rules. The regulatory and compliance costs to us under U.S. securities laws if we are required to comply with the reporting requirements applicable to a U.S. domestic issuer may be significantly higher than the costs we will incur as a foreign private issuer.

#### Our shareholders may face difficulties in protecting their interests because we are a Cayman Islands exempted company.
Our corporate affairs are governed by our Articles of Association, by the Companies Act (As Revised) of the Cayman Islands, or the Companies Act, and the common law of the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under the laws of the Cayman Islands are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. Therefore, you may have more difficulty protecting your interests than would shareholders of a corporation incorporated in a jurisdiction in the United States, due to the comparatively less formal nature of Cayman Islands law in this area.

While Cayman Islands law allows a dissenting shareholder to express the shareholder's view that a court sanctioned reorganization of a Cayman Islands company would not provide fair value for the shareholder's shares, Cayman Islands statutory law does not specifically provide for shareholder appraisal rights in connection with a court sanctioned reorganization (by way of a scheme of arrangement). This may make it more difficult for you to assess the value of any consideration you may receive in a merger or consolidation (by way of a scheme of arrangement) or to require that the acquirer gives you additional consideration if you believe the consideration offered is insufficient. However, Cayman Islands statutory law provides a mechanism for a dissenting shareholder in a merger or consolidation to apply to the Grand Court of the Cayman Islands for a determination of the fair value of the dissenter's shares if it is not possible for the company and the dissenter to agree on a fair price within the time limits prescribed.

Shareholders of Cayman Islands exempted companies (such as us) have no general rights under Cayman Islands law to inspect corporate records and accounts or to obtain copies of lists of shareholders. Our directors have discretion under our Articles of Association to determine whether, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders. This may make it more difficult for you to obtain information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other shareholders in connection with a proxy contest.

#### United States civil liabilities and certain judgments obtained against us by our shareholders may not be enforceable.
We are a Cayman Islands exempted company and substantially all our assets are located outside of the United States. In addition, the majority of our directors and officers are nationals and residents of countries other than the United States. A substantial portion of the assets of these persons is located outside of the United States. As a result, it may be difficult to effect service of process within the United States upon these persons. It may also be difficult to enforce in U.S. courts judgments obtained in U.S. courts based on the civil liability provisions of the U.S. federal securities laws against us and our officers and directors who are not resident in the United States and the substantial majority of whose assets are located outside of the United States. Further, it is unclear if original actions predicated on civil liabilities based solely upon U.S. federal securities laws are enforceable in courts outside the United States, including in the Cayman Islands and Brazil. Courts of the Cayman Islands may not, in an original action in the Cayman Islands, recognize or enforce judgments of U.S. courts predicated upon the civil liability provisions of the securities laws of the United States or any state of the United States on the grounds that such provisions are penal in nature. Although there is no statutory enforcement in the Cayman Islands of judgments obtained in the United States, courts of the Cayman Islands will recognize and enforce a foreign judgment of a court of competent jurisdiction if such judgment is final, for a liquidated sum, provided it is not in respect of taxes or a fine or penalty, is not inconsistent with a Cayman Islands' judgment in respect of the same matters, and was not obtained in a manner which is contrary to the public policy of the Cayman Islands. In addition, a Cayman Islands court may stay proceedings if concurrent proceedings are being brought elsewhere.

#### Judgments of Brazilian courts to enforce our obligations with respect to our Class A common shares may be payable only in reais.
Most of our assets are in Brazil. If proceedings are brought in the courts of Brazil seeking to enforce our obligations in respect of our Class A common shares, we may not be required to discharge our obligations in a currency other than the *real*. Under Brazilian exchange control laws, an obligation in Brazil to pay amounts denominated in a currency other than the *real* may only be satisfied in Brazilian currency at the exchange rate, as determined by the Central Bank, in effect on the date the judgment is obtained, and such amounts are then adjusted to reflect exchange rate variations through the effective payment date. The then-prevailing exchange rate may not afford non-Brazilian investors with full compensation for any claim arising out of or related to our obligations under the Class A common shares.

#### The Economic Substance Act of the Cayman Islands may affect our operations.
The Cayman Islands has recently enacted the International Tax Co-operation (Economic Substance) Act (As Revised), or the Cayman Economic Substance Act. We are required to comply with the Cayman Economic Substance Act. As we are a Cayman Islands company, compliance obligations include filing annual notifications for the Company, which need to state whether we are carrying out any relevant activities and if so, whether we have satisfied economic substance tests to the extent required under the Cayman Economic Substance Act. As it is a new regime, it is anticipated that the Cayman Economic Substance Act will evolve and be subject to further clarification and amendments. We may need to allocate additional resources to keep updated with these developments and may have to make changes to our operations in order to comply with all requirements under the Cayman Economic Substance Act. Failure to satisfy these requirements may subject us to penalties under the Cayman Economic Substance Act.

***Our Class A common shares may not be a suitable investment for all investors, as investment in our Class A common shares presents risks and the possibility of financial losses.***

The investment in our Class A common shares is subject to risks. Investors who wish to invest in our Class A common shares are thus subject to asset losses, including loss of the entire value of their investment, as well as other risks, including those related to our Class A common shares, us, the sector in which we operate, our shareholders and the general macroeconomic environment in Brazil, among other risks.

[**Table of Contents**](#TOC)

Each potential investor in our Class A common shares must therefore determine the suitability of that investment considering its own circumstances. Each potential investor should:

● have sufficient knowledge and experience to make a meaningful evaluation of our Class A common shares, the merits and risks of investing in our Class A common shares and the information contained in this annual report;

● have access to, and knowledge of, appropriate analytical tools to evaluate, in the context of its particular financial situation, an investment in our Class A common shares and the impact our Class A common shares will have on its overall investment portfolio;

● have sufficient financial resources and liquidity to bear all of the risks of an investment in our Class A common shares;

● understand thoroughly the terms of our Class A common shares and be familiar with the behavior of any relevant indices and financial markets; and

● be able to evaluate (either alone or with the help of a financial adviser) possible scenarios for economic, interest rate and other factors that may affect its investment and its ability to bear the applicable risks.

#### ITEM 4. INFORMATION ON THE COMPANY
A. History and Development of the Company

We were founded in 2004. However, our history goes back to 1941, when the grandfather of our CEO and founder, Ari de Sá Cavalcante Neto, acquired a small school in downtown Fortaleza. Over decades, the school grew into a large educational group with several branches providing K-12 education to 6,650 students, becoming recognized for its quality nationally and for successfully preparing students for the most rigorous national and international college admission exams for admission into institutions such as Massachusetts Institute of Technology, Stanford University and Princeton University, and national and international science competitions such as the International Physics Olympiad (IPhO), the International Mathematical Olympiad (IMO) and the International Chemistry Olympiad (IChO).

Colégio Ari de Sá developed a proprietary educational methodology aimed at improving student academic performance. The methodology is based on instilling discipline and a culture of hard work, stimulating students to develop a study routine and to demonstrate a proactive and considerate attitude toward their learning habits.

In 2004, our CEO and founder, Ari de Sá Cavalcante Neto, decided to start an independent company exclusively focused on content and technology for K-12 schools, SAS. The SAS method was created with the aim of offering it as a solution to private schools across Brazil. Our system uses technology as a powerful tool to promote improvements in student performance. This is achieved, in part, by allowing students to prepare for class in advance by using our platform's video lessons, homework tools and daily class reviews, as well as our practical workbooks with class-specific content, homework and performance reports. The SAS method is based on the concept of personalized and adaptive learning, aimed at providing tailored education to each student according to his or her individual needs, with concentration on the main areas in need of improvement, which manifests in higher levels of academic achievement.

Since 2015, we have been investing in technology and our printed methodology has evolved into an educational platform capable of delivering its curriculum content in both printed and digital format. It has also evolved into a robust omni-channel platform, capable of delivering the entire K-12 curriculum in both printed and digital format, with *lecturettes* featuring expert, on-screen teachers and tailored assignments and assessments to engage students and ensure subject-area mastery across all grades.

[**Table of Contents**](#TOC)

With this integrated approach, students can track their progress and performance, teachers have access to real-time data to evaluate students and personalize their teaching, and school administrators have access to their school's performance both on absolute and comparative terms.

![Graphic](arce-20221231x20f004.jpg)

With an asset-light and highly scalable business model that emphasizes operating efficiency and profitability, we were able to grow the number of students served at a 49% compound annual growth rate, or CAGR, since 2006, reaching a total of 2,629,674 students served in 2023, combining organic growth, strategic investments, and acquisitions to grow our K-12 education exposure. These initiatives have helped us identify new business potential to enhance our overall growth prospects, such as education technological features (WPensar, Escola em Movimento, or EEM, Studos and Eduqo), supplemental instruction content (International School, PES, Nave à Vela, or NAV, Escola da Inteligência, or EI, Pleno, PGS, formerly known as Pearson Global School, and Coleção Mentes), digital-native content platform (Geekie), B2C online test prep solution (Me Salva!) and life-long learning platform connecting employees of companies across Brasil to free and discounted courses (Edupass).

On September 25, 2018, the registration statement on Form F-1 (File No 333-7007) relating to our initial public offering of our class A common shares was declared effective by the SEC. On September 25, 2018, we commenced our initial public offering. On September 28, 2018, we closed our initial public offering, pursuant to which we issued and sold 12,777,777 Class A common shares for an aggregate price of U.S.$223,611,098 (R$895.2 million).

On October 29, 2019, we completed a follow-on public offering, consisting of 3,450,656 Class A common shares issued and sold by us, and 4,268,847 Class A common shares sold by certain selling shareholders. The public offering price was US$43.00 per Class A common share. We received net proceeds of US$143.9 million, after deducting US$3.7 million in underwriting discounts and commissions. On November 26, 2019, an additional 661,112 Class A common shares were sold by General Atlantic Arco (Bermuda), L.P. following the exercise by the underwriters of their option to purchase additional shares.

On June 4, 2020, we completed a follow-on public offering, by which General Atlantic Arco (Bermuda), L.P. and Alfaco Holding Inc. sold an aggregate amount of 5,563,203 Class A common shares issued by us, at a public offering price of US$47.70 per Class A common share. We did not receive any proceeds from the sale of Class A common shares by the selling shareholders in connection with this offering.

[**Table of Contents**](#TOC)

On September 8, 2020, we completed a follow-on public offering, consisting of 2,500,000 Class A common shares issued and sold by us. The public offering price was US$44.80 per Class A common share. We received net proceeds of US$109.8 million, after deducting USS$2.2 million in underwriting discounts and commissions.

On January 6, 2021, our Board of Directors approved the Repurchase Program to comply with management long-term incentive plan obligations. Pursuant to the Repurchase Program, we were able to 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, our Board of Directors approved the increase of the share repurchase limit of our Repurchase Program to up to 2.5 million of our outstanding Class A common shares in the open market, based on prevailing market prices, or in privately negotiated transactions, continuing until the earlier of the completion of the repurchase or January 6, 2023, depending upon market conditions. The Repurchase Program expired on January 6, and as of such date, we had purchased an aggregate of 2,031,186 Class A common shares for a total of approximately US$46.8 million under the Repurchase Program.

On November 1, 2021, we cancelled 750,000 treasury shares with the approval of our Board of Directors.

On December 1, 2021, we issued US$150 million in senior notes convertible into our Class A common shares in the amount of: (i) US$100 million to Arcade GF II Holdings, LLC and Arcade OF V Holdings, LLC, entities affiliated with Dragoneer; and (ii) US$50 million to General Atlantic Partners (Bermuda) H, L.P., an entity affiliated with General Atlantic. The convertibles notes bear interest at 8% per annum in fixed Brazilian reais and mature on November 15, 2028. Each note is convertible at the option of the holder into our 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 at the time of signing the investment agreements for the convertible notes.

Following over a decade of growth, and our initial public offering in 2018, we are excited about the future and how technological advances can impact education. We believe that students are increasingly looking for modern, dynamic and client oriented educational platforms and that our tech-enabled approach is positioned to deliver a variety of content and provide a new learning experience that is more effective, personal, engaging, and enjoyable.

**Going Private Transaction**

On November 30, 2022, our Board of Directors received a preliminary non-binding proposal from General Atlantic and Dragoneer to acquire all of our outstanding Class A common shares not held by General Atlantic, Dragoneer or our Founding Shareholders, at a purchase price payable in cash and equal to US$11.00 per Class A common share (which represented a premium of approximately 22% over the closing price of US$9.04 per Class A common share as of November 30, 2022). Pursuant to the terms of the non-binding proposal, the Founding Shareholders would roll over 100% of their Class A common shares and Class B common shares into the Going Private Transaction, and following closing of the Going Private Transaction, the Founding Shareholders would maintain their current economic and voting interests in the Company. On January 26, 2023, the Company announced that the Board of Directors had formed a special committee consisting of four independent directors to evaluate and consider the non-binding proposal and any potential alternative transactions, and to engage in any other actions to further the interests of the holders of our Class A common shares. As of the date of this annual report, the special committee evaluation of the non-binding proposal and any potential alternative transactions is ongoing.

**Acquisitions and Investments**

***Acquisition of isaac***

On January 25, 2021, we entered into a Series B Ordinary Shares Purchase Agreement with INCO Limited, the controlling entity of OISA Tecnologia e Serviços Ltda. ("isaac"). isaac is a vertical platform to address schools' overarching needs with software and financial solutions, including working capital management issues. Pursuant to the purchase agreement, we acquired 8,571,427 series B ordinary shares of isaac, or approximately 30% of its outstanding share capital, for a purchase price equal to R$25.0 million.

On April 22, 2021, we and other investors entered into a Series A and Series A-1 Preferred Shares Purchase Agreement, pursuant to which we acquired 3,653,788 series A preferred shares of isaac for a purchase price equal to R$33.2 million, with the option to acquire an additional 2,935,010 Series A-1 preferred shares, which we exercised on September 17, 2021 for a purchase price equal to R$52.0 million.

On January 2, 2023, and in connection with the isaac acquisition, our board of directors approved the Arco Platform Limited 2022 Share Option Plan, or the "Arco Share Option Plan."

On April 22, 2021, we entered into a purchase agreement for the acquisition of 100% of the equity interest of Eduqo. The transaction closed on July 1, 2021, following CADE's approval.

[**Table of Contents**](#TOC)

***Acquisition of Me Salva!***

On March 10, 2021, we acquired 60% of the equity interest of Me Salva! for a purchase price of R$27.6 million. Me Salva! is an online educational solution that prepares students to be admitted to the Brazilian universities, through recorded and live classes, comprehensive exercises, essay writing tools, assessment tests, 1-on-1 tutoring and personalized study plans. On December 9, 2022, we acquired the remaining 40% stake for a purchase price of R$9.6 million.

***Acquisition of COC and Dom Bosco learning systems and PGS and Coleção Mentes do Amanhã supplemental solutions***

On March 6, 2021, we entered into a definitive agreement with Pearson Education do Brasil Ltda. ("Pearson") to acquire 100 % interest in P2D, the owner of COC and Dom Bosco learning systems, for the total amount of R$920 million, of which (i) 80% was paid on closing, and (ii) the remaining 20% of the purchase price was paid on the first anniversary of the closing date, as adjusted. The transaction also includes an agreement with Pearson to distribute some supplemental educational solutions for K-12 schools in Brazil.

On October 1, 2021, following final approval from CADE for this acquisition, we closed the transaction. The payment terms set forth in the purchase agreement were updated upon closing of the transaction to a total purchase price of R$800.4 million, adjusted for COC's and Dom Bosco's cash and working capital positions as of September 30, 2021, paid in a single installment on the transaction closing date. The merger of COC and Dom Bosco with, and into, CBE, our subsidiary, was concluded in the second quarter of 2022.

In addition to the acquisition of P2D, CBE entered into a Commercial Cooperation and Distribution Agreement with Pearson pursuant to which CBE would be the sole distributor in Brazil of the PGS bilingual courseware and teaching methodology and the supplemental solution focused on 21st century skills Mentes do Amanhã, with the option to acquire these business lines in the long term.

CBE is licensed to use the PGS trademark until 2026, when a new brand is expected to be launched.

***Acquisition of Escola da Inteligência***

On December 2, 2020, we closed the acquisition of Escola da Inteligência, the leading solution in social-emotional learning (SEL) in Brazil, which was approved by CADE, with no restrictions, on the same date. This transaction broadens our supplemental market presence by adding a strong brand to its portfolio. We believe there is a favorable market trend for SEL, pushed forward by the COVID-19 pandemic, and that Escola da Inteligência is well positioned to capture this demand outside and within our school base.

The acquisition involves only the private sector business of Escola da Inteligência and under the terms of transaction, we acquired 60% of Escola da Inteligência's shares for a purchase price of R$288 million, R$200 million of which was paid at closing and R$88 million of which was paid in the second quarter of 2021. We will acquire the remaining 40% stake in the second quarter of 2023, the purchase price for which will be calculated considering 6 times the 2023 ACV plus effective cash generated since the acquisition, multiplied by 40%. The remaining shares will be transferred to us on the day of such payment.

***Acquisition of Studos***

On September 21, 2020, we acquired 100.0% of the outstanding shares and voting rights of Studos, a leading provider of adaptive solutions.

On August 1, 2022, Studos was fully merged with, and into, Atech.

[**Table of Contents**](#TOC)

***Investment in Bewater Ventures I GA***

On July 24, 2020, we acquired a 14.48% interest in Bewater Ventures I GA, a fund legally managed by Paraty Capital, through the purchase of 9,670 Class B quotas for R$9.7 million. As a result of the fund's capital call, we currently own 9,713 Class B Shares, equivalent to an 11% interest, representing a total investment of R$9.8 million. The fund's main goal is the minority investment in Grupo A, a company that provides educational solutions for higher education, which happened subsequently to our investment. For further information, see note 11 to our audited consolidated financial statements.

***Acquisition of Positivo Soluções Didáticas***

On November 1, 2019, we closed the acquisition of Positivo, one of the largest K-12 content providers to private schools in Brazil, and other companies of the Positivo Group (as defined below), or Positivo Acquisition. Positivo is part of a group founded in 1972 in Curitiba by a group of teachers as a preparatory course focused on admission exams to universities in the state of Paraná, or Positivo Group. The preparatory course reached 2,300 enrolled students in the first year of operation and its success led the group to quickly open new schools for all K-12 grades under the brand *Colégio Positivo*. In a short period of time, the proprietary content and methodology developed and used by *Colégio Positivo* schools achieved significant recognition among teachers, parents and students. The high-quality content and its dynamic approach led to the foundation of Positivo in 1979, allowing the Positivo brand to expand far beyond the reach of Colégio Positivo, being adopted by third-party schools in several cities of the state of Paraná and other Brazilian states.

With over 40 years of brand legacy, Positivo evolved to become a leading content providing platform that transforms the lives of many students of private schools across all Brazilian states. This is a vibrant ecosystem with several opportunities to effectively address the needs of parents, students, teachers and school owners. Positivo is focused on building long-term relationships with partner schools and this approach is an important factor to its success, proven by the fact that more than 50% of its client base has over ten years of relationship.

This carve-out acquisition encompassed only the private school learning systems and did not include the other assets of the Positivo Group, such as the public-school learning system, the printing company, the *Universidade Positivo* post- secondary education business, and the *Colégio Positivo* proprietary schools.

The agreed purchase price was R$1,684.8 million (equity value), of which (i) 50% was paid in cash on the transaction closing date, and (ii) the remaining 50% will be paid in four installments as follows: (1) 10% per year to be paid in cash in each of 2021 and 2022, and (2) 15% per year to be paid in cash in each of 2023 and 2024, all as adjusted by the Brazilian average interbank overnight interest rate (*certificado de depósito interbancário*), or the CDI rate.

The Positivo Acquisition allowed us to increase our student base twofold, reaching over 1.2 million students in 2019. In addition, it allowed us to accelerate our growth with the same B2B2C business model, with predictable subscription- based revenue, high operating leverage and cash flow conversion while remaining asset-light. By adding complementary assets, Positivo also enables us to broaden our product offerings and expand our footprint. Positivo comprises two different brands with reciprocal business profiles: (i) *Sistema de Ensino Positivo*, or SPE, an educational solution consisting of content, technology and services provided to private schools serving upper-middle-income students; and (ii) *Conquista Solução Educacional*, or Conquista, which is focused on private schools serving lower-middle income students. Together, SPE and Conquista enhance our Core Curriculum offering, allowing us to reach a larger base of schools at different price points. In addition, Positivo also owns Positivo English Solution, or PES, an affordably priced second language-offering that enhances our Supplemental Solutions.

Positivo has a strong presence in the South and Southeast regions of Brazil, with relatively low geographic overlap with our student base. The acquisition will also allow us to add opportunities through our scale and technology, strengthening our capacity to invest in high quality content and technology and enabling us to enhance our student base experience and academic outcomes through technology improvements and our cross-selling capabilities.

On August 1, 2020, Positivo was fully merged with, and into, CBE.

[**Table of Contents**](#TOC)

***Acquisition of EEM (also known as Atech or ArcoTech)***

On June 4, 2019, we closed the acquisition of EEM, or the EEM Acquisition, an app developer that enhances communication between schools and parents by providing chat-based interactions, location-based identifications, Net Promoter Scores, or NPS, tool to assess parent's satisfaction and pilot project related to payments. The EEM Acquisition provided us with new capabilities that further increases our value proposition to partner schools, parents and students, and also allowed us to access EEM's network of schools. The purchase consideration transferred was R$18.3 million. The amount of R$16.1 million was paid on the closing date, the amount of R$0.3 million was paid on June 29, 2019, and the deferred payment in the amount of R$1.9 million, which was retained for a period of two years as guarantee for the payment of any contingent liabilities, was released in accordance with the provisions of the agreement. Any remaining balance will be transferred to the former owners of the acquired entity.

On June 27, 2022, we changed the name of EEM to Atech (also known as ArcoTech). On August 1, 2022, Eduqo and Studos were fully merged with, and into, Atech.

***Acquisition of NAV***

In May 2019, we acquired a 13.2% interest in the share capital of NAV, a developer of competence-based learning content present in more than 50 schools and reaching 16,000 students, according to NAV's website, for the total subscription price of R$4.2 million, hereinafter referred to as the NAV Acquisition. Pursuant to the investment and share purchase agreement, we have agreed to acquire the remaining 86.8% of the outstanding share capital of NAV in three tranches. We acquired: (i) Tranche 1, corresponding to 37.8% of the outstanding share capital of NAV, on October 29, 2019, for R$21.1 million, and (ii) Tranche 2 and Tranche 3, corresponding to 24% and 25% of the outstanding share capital of NAV, respectively, on February 15, 2021, for the total amount of R$22.6 million. By anticipating the payment of Tranche 3, NAV became our wholly owned subsidiary on February 25, 2021. On October 1, 2021, NAV was fully merged with, and into, CBE.

NAV enhances our Supplemental Solutions offering and the cross-selling capacity of our Core Curriculum offering through a competence-based curriculum to address 21st century skills. The EEM Acquisition and NAV Acquisition provide us with new capabilities that further increases our value proposition to partner schools, parents and students, and also allows us to access each acquisition's network of schools. Through projects, problem solving and technology, NAV helps students develop transferable skills, such as critical and creative thinking, and communication skills.

***Acquisition of Geekie***

In December 2016, we acquired a 6.54% interest in Geekie, an entity that provides technology for adaptive assessment and learning products and engages in the production, development and licensing of software tailored to the specific requirements of education sector customers. On July 3, 2018, we acquired an additional 1.51% interest in the share capital of Geekie, increasing our total interest to 8.05%.

On September 20, 2019, we acquired an additional 0.96% interest in the share capital of Geekie through a capital increase of R$1.2 million.

[**Table of Contents**](#TOC)

On November 27, 2020, we entered into a new shareholders' agreement with the other Geekie's shareholders, by which we acquired control of Geekie and started to consolidate Geekie in our financial statements as our subsidiary. We acquired the remaining 42.58% interest in Geekie's share capital in May 2022, for a purchase price equal to R$239.6 million, which was based on the ACV of Geekie for 2022 for its core solution and the company's debts, and the net revenue of Geekie's additional products as of January 2023. The purchase price is payable in two installments, the first instalment of R$223.9 million was paid in May 2022, and the second installment of R$15.7 million will be paid in January 2023.

On October 1, 2022, Geekie was fully merged with, and into, CBE.

***Acquisition of SAE***

In June 2016, we acquired a 70% interest in the share capital of SAE. In October 2017, we acquired the remaining 30% in the share capital of SAE. We currently hold a 100% interest in the share capital of SAE. The investment in SAE added a new platform for the Company's Core segment with a different pedagogical approach and different pricing point. This acquisition enabled the Company to serve a broader range of schools, allowing us to maximize our market reach and penetration. Thus, with the SAE solution, the Company started to offer a basic subscription solution focused on upper middle income private schools.

***Acquisition of International School***

In December 2015 and January 2017, our subsidiary CBE acquired 40% and 11.48% interests, respectively, in the share capital of International School from Mr. Ulisses Borges Cardinot, pursuant to an investment and other covenants agreement (*Contrato de Investimento e Outras Avenças*) dated December 21, 2015 (as amended on January 28, 2016 and January 23, 2017), or the Investment Agreement. Mr. Cardinot is currently the chief executive officer of International School pursuant to a shareholders' agreement between Mr. Cardinot and CBE.

The Investment Agreement contains certain contractual arrangements for the acquisition by CBE of the remaining 48.52% interest in the share capital of International School held by Mr. Cardinot, or the Remaining Interest, divided in two steps: (1) 25% of the share capital between January 1, 2020 and April 30, 2020 at a purchase price equal to the product of 30% and 10 times the accounting EBITDA of International School for the 2019 school year (twelve-month period between October and September) (subject to certain adjustments); and (2) 23.52% of the share capital between January 1, 2021 and April 30, 2021 at a purchase price equal to the product of 30% and 10 times the accounting EBITDA (as defined in the Investment Agreement) of International School for the 2020 school year (subject to certain adjustments). In addition, Mr. Cardinot may elect to allocate up to 50% of the total purchase price to subscribe for CBE shares (which would be valued at the product of 30% and 10 times the accounting EBITDA of CBE (subject to certain adjustments) for the applicable school year).

Pursuant to the Investment Agreement, upon the approval of an initial public offering of CBE (1) certain contractual arrangements for the acquisition by CBE of the Remaining Interest are accelerated; and (2) Mr. Cardinot's option to allocate up to 50% of the total purchase price to subscribe for CBE shares must be exercised by Mr. Cardinot at the shareholder meeting approving an initial public offering by CBE. We recognized a financial liability as of December 31, 2022 in the amount of R$424.8 million, which represented the present value of the estimated amount payable to Mr. Cardinot. This financial liability may vary in subsequent financial periods and depending on the final basis for calculation of the purchase price of the Remaining Interest and it will be updated accordingly in our financial statements for future financial periods. See "Item 8. Financial Information—A. Consolidated statements and other financial information— Legal Proceedings" for more information on this matter.

B. Business Overview

Our mission is to transform the way students learn by delivering high-quality education at scale through technology to K-12 schools and students.

We provide a complete pedagogical system with technology-enabled features to deliver educational content to private schools and students in Brazil. Our turnkey curriculum solutions provide educational content in both printed and digital formats delivered through our platform to improve the learning process.

We have an asset-light, highly scalable business model that emphasizes operational efficiency and profitability. In our B2B2C Core Curriculum and Supplemental Content Solutions, we operate through long-term service contracts with private schools. These contracts generally have initial terms that average three years, pursuant to which we provide educational content in printed and digital format to private schools. Our revenue is driven by the number of enrolled students at each customer using the solutions and the agreed-upon price per student per year, all in accordance with the terms and conditions set forth in each contract. As a result, we benefit from high visibility in our net revenue and operating margin, which we calculate by dividing our operating profit by net revenue over a given period. Our annual retention rate was 91% in 2022, 93% in 2021 and 93% in 2020, which makes our recurring revenue base highly stable.

Our network in our B2B2C Core Curriculum and Supplemental Content Solutions as of March 30, 2023, consisted of 8,071 partner schools compared to 7,666 schools as of March 31, 2022, 6,119 schools as of March 31, 2021, and 5,414 schools as of March 31, 2020, representing annual growth rates of 6%, 31.7% and 13.0%, respectively.

We had 2,629,674 expected number of enrolled students, or Number of Enrolled Students, across all Brazilian states as of March 30, 2023, compared to 2,279,025 Number of Enrolled Students as of March 31, 2022, 1,785,576 as of March 31, 2021, and 1,362,141 as of March 31, 2020, representing annual growth rates of 15.4%, 27.6% and 31.1%, respectively. During the COVID-19 pandemic, our partner schools experienced atypical dropout rates from March 31 to September 30 resulting in a material difference between our Number of Enrolled Students and the Final Number of Enrolled Students as of September of each year. In 2022 our partner schools did not experience these atypical dropouts, and dropout rates reverted to pre-pandemic trends and there were no material variations to the Number of Enrolled Students.

[**Table of Contents**](#TOC)

Our B2B2C Core Curriculum and Supplemental Content Solutions business model has allowed us to grow and achieve profitability since our founding. Our net revenue totaled R$1,775.4 million, R$1,232.1 million and R$1,001.7 million in 2022, 2021 and 2020, respectively, representing annual growth rates of 44% and 23% in 2022 and 2021, respectively. We generated operating profit of R$295.5 million, R$129.4 million and R$135.5 million in 2022, 2021 and 2020, respectively. We had a profit/ of R$39.5 million in 2022, a loss of R$158.1 million in 2021 and a profit of R$16.8 million in 2020, respectively. Our partner school base is highly diversified, which reduces our dependence on a concentrated number of large clients. Our 10 largest clients represented only 3.1%, 3.4% and 2.6% of our ACV Bookings in 2022, 2021 and 2020, respectively.

ACV Bookings for the Supplemental Solutions (both B2B2C Supplemental Content Solutions and other supplemental solutions) totaled R$409.8 million for the 2023 school year, resulting in a 3% ACV market share of the total addressable market of such segment in Brazil, which includes after-school education, based on Educa Insights' 2021 assessment of the private K-12 market. In addressing the core solutions market, Arco's ACV Bookings for the 2023 school year of R$1,521.2 million results in a 20% core solutions market share, which considers the number of students in the Brazilian K-12 market according to the 2022 INEP Census.

We believe that the quality of our platform, together with the credibility of our client base and the strong reputation of our brand, has driven our significant growth, allowing us to expand our footprint quickly and efficiently in Brazil since our founding. According to the 2023 university admission data published through the Brazilian Unified Selection System (*Sistema de Seleção Unificada*), or SISU, 2,399 students within our partner school base have been accepted in the first place of their respective majors (a 59% increase when compared to the 1,513 students in 2022, considering the same solutions). The number of students within our partner school base that were accepted in top 10 positions increased to 11,114 students (a 53% increase when compared to the 7,242 students in 2021, considering the same solutions).

In March 2021, Arco started serving students directly through the acquisition of Me Salva!, a B2C test prep player. The online solution offers recorded and live video classes, comprehensive exercises, essay writing tools, assessment tests, 1-on-1 tutoring and personalized study plans. Despite currently representing only a small and immaterial part of our business, this vertical allows Arco to tap a large and underserved market of students from public schools that lack quality education at affordable prices. We also plan to reinforce our Supplemental portfolio by offering schools a solution on the test prep and tutoring vertical, developed on top of Me Salva!'s know-how and digital offering, allowing them to better prepare their students for the ENEM.

#### Context
The 21st century has been characterized by rapid and accelerating technological innovation, with students at the forefront of the adoption of new technologies. We believe that we can deliver a more effective, personal, engaging, and enjoyable learning experience for students by combining high quality proprietary content and software applications in our simple, integrated, and personalized educational platform. We aim to move beyond traditional educational models used by schools by empowering educators, school administrators and students to achieve their highest potential through our educational platform.

We founded our company with the aim of creating high quality products that simplify learning and make the education process more efficient. Traditionally, school administrators required a multitude of vendors for developing content, engaging in teacher training, and commercializing and managing K-12 education. Simultaneously, students acquired educational content through textbooks from various publishers across retail channels. Our platform aims to replace this multitude of third- party educational providers with a streamlined, one-stop solution that delivers high quality education at scale.

Our Core Curriculum and Supplemental Solutions enable students, teachers, and school administrators to have access to engaging and easy-to-use resources that propel academic success and meet students' diverse learning needs. Pairing our printed and digital curriculum with real-time data and teacher-led learning allows us to personalize learning at the individual level, improving both individual student and aggregate school performance.

[**Table of Contents**](#TOC)

We develop our educational content using a model based on extensive research and performance-based standards. We combine printed and digital content with online lecturettes featuring expert, on-screen teachers and tailored assignments and assessments to engage students and help them master their subject areas. With this integrated approach, students can track their progress and performance, teachers can access real-time data to evaluate students and personalize their teaching and school administrators can better manage their school's performance both on absolute and comparative terms.

The increase in internet penetration and the rapid increase in the use of mobile devices and cloud-based services is broadening access to educational content and services and expanding the potential reach of educational institutions. Our platform does not require our partner schools to make any significant capital expenditures or setup investments and is compatible with most mainstream computing platforms (including tablets and mobile phones). Our solutions are designed to be highly interactive and enjoyable, which we believe results in enhanced educational outcomes when compared to traditional models.

**Underlying Trends**

We believe that the strength of our business and growth prospects is supported by strong underlying market and industry trends, including:

#### Demand for quality education is driving a shift from public to private K-12 education
A wide gap in the quality of education exists between public and private K-12 institutions in Brazil, and within the private school market itself. Test performance is significantly better in private primary and secondary education, as illustrated by the average quality index differential measured by IDEB, the basic education development index calculated by INEP. As of December 31, 2021 (last data available), private K-12 education schools had an average education quality index score 28% higher than that of public primary and secondary schools across all school years according to the IDEB quality index differential. As a result, over the last ten years, student enrollments in private K-12 institutions have increased/ 8.1%, to 9.0 million in 2022 from 8.3 million in 2012.

#### Technological innovation is driving enhancements in private K-12 education
We believe the digital transition observed in recent years can provide significant benefits, and opportunities for, education service and content providers, such as:

● revenue diversification, by means of technological developments in education platforms, such as new tools or capabilities, may be sold for different purposes and to different consumers;

● customization enabled by technology and tied to a soft adaptation, which allows for distribution to different customers and a scaling by companies that offer different solutions; and

● margin gains, given a lower cost per student and a larger consumer base that is accessible through technological developments.

Technology has created opportunities to make learning more affordable, accessible, flexible, personal and effective.

Classroom instruction and delivery models are changing and are likely to have a substantial impact on the industry.

As a result of the COVID-19 outbreak, which was declared a pandemic by the World Health Organization in March 2020, state and local authorities in Brazil suspended school operations. On-site school activities were postponed, forcing schools to teach classes remotely. Although schools have historically been late adopters of technology and resistant to change, the impacts of the COVID-19 pandemic led them to turn to technology to continue offering their students educational content and pedagogical support. As part of our sales strategy during the COVID-19 outbreak, we unbundled part of our solutions throughout 2020, allowing approximately 400 schools to use the trial versions of our products and therefore creating a large pipeline of leads for the following commercial cycles.

[**Table of Contents**](#TOC)

We believe that as we have rapidly evolved our solutions to meet schools needs during the COVID-19 pandemic, we are now uniquely positioned to benefit from the higher willingness from schools to adopt learning systems that offer quality content combined with technological features that will improve the learning experience.

#### Importance of K-12 performance in university admissions processes
The best higher education institutions in Brazil are public, with a highly competitive admissions process based largely on challenging standardized admissions exams. According to the World University Rankings 2023 published by Times Higher Education (THE), 22 out of the 25 top-ranked universities in Brazil were public as of August 2022.

Competition for admission into public universities in Brazil is historically high, according to 2023 SISU data, there were on average 9 applicants per available seat in public universities. As a result of this competition, parents are increasingly focused on schools that over-perform in the standardized university admissions tests. Our solution is designed to enhance our students' ability to perform on these exams.

***Expansion of school hours and after-school programs including, but not limited to, English as a Second Language, or ESL, bilingual programs and 21<sup>st</sup> century skills programs***

The increased focus on education has led to an increase in the length of the average school day. After-school education, comprising of tutoring, language courses, 21<sup>st</sup> century skills, such as critical thinking, leadership, collaboration and communication skills, and robotics, among other extracurricular activities, is also becoming more popular, offering a variety of training and learning programs in which students can participate according to their personal interests and preferences. Language courses are among the most popular after-school activities and represent an area with significant room for growth, primarily as a result of:

● the increasing relevance of languages, especially English, in a globalized context;

● the low English proficiency level in Brazil; and

● the emphasis in language classes currently offered by K-12 schools on reading and written communication, despite the fact that the labor market relies more heavily on oral communication (which also creates a market for bilingual schools).

For many parents, after-school education is considered a lifeline that helps them work without worry and balance their schedules, given (i) that Brazil has one of the highest average working hours per week in the world, and (ii) the increased participation of women in the workforce. In addition, an increase in disposable income has increased demand for private education and after-school programs, and parent expectations for their children's education are high considering the strong competition to gain admission into top public universities. Accordingly, supplemental education represents a growing opportunity for private institutions, with an addressable market of R$15.4 billion compared to R$5.2 billion of potential market for private K-12 learning systems and textbooks in Brazil, based on Educa Insights' assessment of the private K-12 learning systems market as of December 2021. This is especially the case given the wide variety of supplemental solutions that can be offered to students during regular and after-school hours.

#### Obsolescence of traditional content distribution models
We believe that traditional content distribution models are becoming obsolete. Traditional educational publishers are almost exclusively focused on physical textbooks, which they sell through retailers rather than directly to schools. These traditional suppliers have limited capability to develop and offer integrated digital solutions to schools, teachers, and students, and typically rely on third-party authors, illustrators and graphic designers to develop new content. In contrast, because of our robust technology backbone, use of data and strong relationships with teachers and administrators, we can offer a comprehensive solution and content that is continuously updated and improved.

[**Table of Contents**](#TOC)

#### Limited and unintegrated product offering
Due to the lack of turnkey education solutions, school administrators often rely on a multitude of third-party vendors for K-12 educational content, teacher training, student testing, management, and communication tools.

Traditional education providers have struggled to develop mission critical education platforms for several reasons, including the significant costs associated with the development of content and technologies, as well as the lack of extensive in-house technological expertise. In addition, developing a comprehensive and effective methodology is difficult to achieve since it requires many years of proven educational experience and a successful track record.

We can replace a multitude of third-party educational vendors with a streamlined and consolidated solution, offering a one-stop shop that delivers enhanced learning across the educational spectrum.

#### Our Market Opportunity
According to Educa Insights' assessment of the private K-12 market, the existing addressable market in Brazil for core curriculum solutions and supplemental solutions totals approximately R$20.6 billion in sales revenues as of December 2021 of which we currently capture approximately 9% based on our ACV Bookings as of March 30, 2023. We can address this market by launching new solutions and entering new categories.

Our B2B2C model benefits from structural differences in our market, when compared to the education markets in the United States and Europe. Private schools in Brazil are generally for-profit institutions, and the private education market in Brazil is large and highly fragmented, primarily a result of lower overall levels of government funding for K-12 public education. As of December 31, 2022, approximately 9.0 million students were enrolled in approximately 41,011 private schools (19.0% of the total number of K-12 students in Brazil), according to the INEP and the IBGE. In addition, the national curriculum set by the Ministry of Education requires standardized content across Brazilian schools, which helps create demand for a unified curriculum. Finally, teachers' unions in Brazil are relatively less influential than their counterparts in the United States and Europe, where such unions often serve as obstacles to the adoption of innovations.

We believe that the challenges inherent in the traditional content distribution model, coupled with increasing demand for modern content and integrated value-added services, present a unique market opportunity for our business. By providing an affordable, modern, and efficient platform, we believe that we can continue to disrupt the Brazilian education market and increase our penetration into current and new markets.

As for our B2C model, we benefit from the intense competition for higher education admission driving demand for test prep, as the best universities in Brazil are public (and costs are subsidized by the government) and offer a leap in earnings potential for students. As a result, parents and students demonstrate unmet needs and willingness to pay for access to top quality content, individualized learning, and convenience. The K-12 tutoring, and test prep markets are very fragmented and currently mostly offline, while we observe an increasingly preferred for online due to cost, quality and convenience.

#### The Arco Way
Quality, a key component for the success in the K-12 market, is always at the center of our decisions and it has been the gear of our virtuous cycle over the years. As we continuously invest in quality and customer support, we assist our schools to achieve higher academic results. This is illustrated by the ENEM strong results of our partner schools, one of the main metrics to measure education quality in Brazil.

According to the 2023 SISU data on university admissions, 2,399 students within our partner school base have been accepted in the first place of their respective majors (a 59% increase when compared to the 1,513 students in 2022, considering the same solutions). The number of students within our partner school base that were accepted in top 10 positions increased to 11,114 students (a 53% increase when compared to the 7,242 students in 2021, considering the same solutions). The strong results achieved by our partner schools improve our brand equity, help build our reputation and consequently, tends to contribute to our healthy, sustainable organic growth.

As we grow and add new partner schools, our network becomes a powerful source of leads generation and data. In addition, the increased scale allows us to reinvest in content, quality, and service, contributing to the positive loop.

![Graphic](arce-20221231x20f005.jpg)

#### Our Business Model
*Our B2B2C model is financially aligned with our partner schools.* Our revenues consist of wholesale content fees paid by our partner schools annually on a per-student, per-year basis. On average, partner schools charge students' parents an incremental markup on top of our wholesale fees, ensuring that their incentives are aligned with ours. Accordingly, we provide a supplemental revenue stream to our partner schools through our B2B2C model, which is a feature that the traditional education model does not employ. Once schools adopt our platform for a particular class year, access to, and payment for, our platform becomes mandatory for all enrolled students in each class year, and such payments are charged as a supplement to tuition. Typically, we revise our contract fees annually, in line with our price-setting policies, which are usually above published inflation indices, to account for improvements in our platform and for changes in our costs and expenses structure.

[**Table of Contents**](#TOC)

The following chart illustrates our business-to-business-to-consumer (B2B2C) model:

![Graphic](arce-20221231x20f006.jpg)

*Our B2B2C model has long-term contracts with private schools, high retention rates and high financial predictability.* Our three-year standard contract provides a revenue stream with long-term cash flow visibility. We have a lead time (which we define as the period from the moment of first contact to the execution of a contract) for the acquisition of new partner schools, and we typically enter into contracts with new partner schools within one year from the moment of first contact. Once our content is adopted, switching costs (which are the costs that schools incur as a result of switching to our platform) and time associated with updating the teaching curriculum for each class year work to our advantage. A portion of our historical average 6.0% annual attrition rate is attributable to the early termination or suspension of performance by us, at our option, of contracts with certain partner schools as a result of their failure to timely pay our contract fees.

*Our B2B2C model is asset-light and scalable business model, with high operating leverage and limited capex requirements.* By outsourcing distribution activities to third parties and developing standard solutions, we have an asset-light and scalable business model that enables us to quickly expand our customer base with low associated expenses and capital expenditures, including 100% digital marketing and remote negotiation processes with our customers. This allows us to increasingly expand our margins as we grow the number of students we serve, while generating cash to fund the development of new products and features, as well as identify acquisitions and strategic investments.

*Our platform on the B2B2C model is difficult to replicate.* We have continuously developed our platform since our founding, with the benefit of over 50 years of an evolving educational methodology and a dedicated team of education specialists focused on developing and improving our Core Curriculum and Supplemental Solutions materials. Accordingly, we believe that the depth of our educational content and the technological experience necessary to develop our products makes our platform difficult to replicate.

*Our B2C model is 100% subscription-based and has attractive unit economics.* Our revenues consist of retail content fees paid by students upon subscribing for one of our plans. Despite shorter-term when compared to our B2B2C model, customer acquisition cost is also reduced, leading to profitable unit economics.

#### Our Solutions
In the education sector, we believe that quality is fundamental. Our platform on the B2B2C model was developed with the benefit of over 50 years of an evolving educational methodology and robust track record of academic results. Our track record of high-performing educational outcomes motivated us to create a digital, technology-driven product that could deliver high quality education at scale.

[**Table of Contents**](#TOC)

Additionally, Positivo is the pioneer in the learning system segment in Brazil and has served the K-12 private school market for more than 40 years. The pedagogical methodology developed inside the *Colégio Positivo* schools was transformed into a comprehensive educational solution that quickly expanded to other schools in Brazil. Over time, Positivo expanded its product offering to address different profiles of schools and increase its addressable market.

We provide a complete suite of turnkey curriculum solutions and technology-enabled features to help our students, teachers, partner schools and parents, targeting our students' educational success.

The platform also enables teachers to generate exams based on a given class profile, using a database containing a broad range of questions.

● *Interactive learning*: Leveraging the combined abilities of our pedagogical and EdTech teams, we have created augmented reality and video features throughout our materials, allowing students to point their digital devices at certain sections in our materials to view educational animations or recorded videos that provide further information on the topic in question, contributing to a more interactive and engaging learning experience.

● *Students and teachers web portal*: An online environment aggregating relevant content for students and teachers by grade in the form of digital classes, exam database, assessment templates, teachers' guides and lesson plans, exams and textbooks' problem solving in addition to articles and general educational-related tips.

● *In-app communication*: A responsive, simple and user-friendly communication tool for partner schools, students and parents, giving them access to exam results and problem solving, video classes, student grades, as well as the school calendar and attendance records.

● *Support to partner schools:* Back-office management, educational consulting services, training programs for teachers to assess and improve the quality of their teaching methods and marketing advisory services.

As part of our Core Curriculum, we offer complementary support to partner schools consisting of:

● *Back office management tools:* HR tools with financial, student recruiting and administrative features.

[**Table of Contents**](#TOC)

● *Educational consulting services to partner schools:* Personalized support to ensure complete understanding and appropriate implementation of our learning platform. This includes constant support to partner schools throughout the school year in connection with educational practices, administrative, human resources and financial aspects, development of customized students' assessment models, organization of education congresses and pedagogical meetings, as well as parents and students counselling.

● *Training programs for teachers and school administrators:* A suite of materials to allow partner schools and teachers to assess the quality of their teaching methods and how they can improve them through our learning platform. This includes local, regional and national educational congresses, forums, seminars and lectures, in addition to training sessions.

● *School marketing advisory:* A comprehensive range of marketing and communication materials, events and support through our learning platform, including marketing brochures and recruitment campaigns.

Our Supplemental Solutions comprise of (i) Supplemental Content Solutions, providing additional value-added educational content for which partner schools can opt-in as an addition to our Core Curriculum, and (ii) Other Supplemental solutions to schools and students such as education technological features schools (WPensar, EEM, Studos and Eduqo), B2C online test prep solution (MeSalva!) and life-long learning platform connecting employees of companies across Brasil to free and discounted courses (Edupass).

We have a Supplemental Content solutions market share of 3%, calculated by dividing Arco's Supplementary Solutions ACV Bookings for the 2022 school year by the total addressable market for Supplemental Solutions, which consists of English as a Second Language (ESL) bilingual programs (International School, PES and PGS) and 21st century skills programs (Pleno, Escola da Inteligência, NAV and Mentes), based on Educa Insights' assessment of the private K-12 market.

We started offering Supplemental Solutions through an ESL bilingual program in 2015, following our acquisition of an interest in International School. International School provides students with an internationally oriented education, in a multicultural environment, based on a curriculum like the International Baccalaureate or Cambridge International Examinations. We intend to add non-core supplemental educational modules to our Supplemental Solutions portfolio over time.

Upon the acquisition of Positivo in 2019, our Supplemental Solution also offers the PES, a bilingual program with an approach that promotes integrated learning of content and language, in partnership with Cambridge University Press. The program consists of 2-5 weekly hours of English classes with several tools to develop the skills needed to communicate well. PES also provides teachers' training and pedagogical support to its partner schools. PES was launched in 2015 and has a strong cross-sell potential within our Core Solution partner schools' network and to expand to schools that have not yet adopted our solution.

In 2019, we started investing in the development of a social-emotional supplemental solution called Pleno, developed to meet schools' demand for a product that goes beyond the student's cognitive development. Through the same B2B2C business model and integrated with the K-12 curriculum, Pleno helps students to develop competencies and skills, such as self and social-awareness, design thinking and entrepreneurship.

In February 2021, we concluded the acquisition of NAV, a developer of competence-based learning content, enhancing our Supplemental Solutions offering through a competence-based curriculum to address 21st century skills, which is in our portfolio since May 2019. Through projects, problem solving and technology, NAV helps students develop transferable skills, such as critical and creative thinking, and communication skills.

In December 2020, we concluded the acquisition of Escola da Inteligência, the leading solution in social-emotional learning (SEL) in Brazil, based on a proprietary methodology and great reputation in the K-12 market.

In February 2022, we acquired PGS, a K-12 bilingual courseware and teaching methodology, formerly known as Pearson Global School, complementing our ESL offering with a high-quality solution with a differentiated pricing point; and Mentes do Amanhã ("Mentes"), a K-12 supplemental solution focused on 21st century skills (social-emotional learning, financial literacy, and technology).

[**Table of Contents**](#TOC)

We intend to continue adding supplemental educational modules to our Supplemental Content Solutions portfolio over time, broadening Arco's supplemental market presence by adding high-quality solutions with pricing complementarity to our current offering. Arco believes in the large potential for English as a Second Language and in the favorable market trend for 21st century skills. An even stronger portfolio better positions Arco to capture this demand outside and within Arco's school base. The key attributes of our Supplemental Solutions are:

● *Proprietary applications:* Two complementary applications providing content and English-based games that form part of students' school year collections, including a communications tool for partner schools, students and parents.

● *Robotics:* Pioneering activities that enable students to build and program their own Lego <sup>®</sup> robots as a way to maximize learning beyond the classroom experience.

● *Combination of concrete materials and animations:* Print and digital textbooks combined with interactive animations, educational videos and exercises.

● *Crowdsourced education:* Collaborative and versatile platform for classrooms that allows students to collaborate in project building and problem solving.

Our Supplemental offering also includes other solutions such as technological and managerial features to partner schools, B2C test prep and education as a benefit.

Our tech and managerial features include (i) WPensar (acquired in 2015), a company that develops and licenses school management systems software, (ii) Escola Em Movimento, or EEM (acquired in 2019), an app developer that enhances communication between schools and parents by providing chat-based interactions, location-based identifications, Net Promoter Scores, or NPS, tool to assess parent's satisfaction and pilot project related to payments, (iii) Studos (acquired in 2020) a leading provider of adaptive solutions, and (iv) Eduqo (acquired in 2021), a learning management system (LMS) platform that connects students and professors, and also offers question banks, exams and diagnostics to its clients.

In March 2021, we acquired Me Salva!, a B2C digital test prep solution, allowing Arco to start delivering high quality education to public sector students at affordable prices. Finally, in February 2022, we acquired Pearson Global School, a K-12 bilingual courseware and teaching methodology, and Coleção Mentes, a K-12 supplemental solution focused on 21st century skills (social-emotional learning, financial literacy and technology).

In September 2021, we acquired EduPass, a company that offers education as a benefit to corporate clients and aims to prepare the Brazilian workforce to the future of work through education and upskilling.

In January 2023, we acquired isaac, a vertical platform to address schools' overarching needs with software and financial solutions, including working capital management issues.

#### Our Team and Culture
We have a strong corporate culture, and we encourage our employees to actively adopt it. We believe in:

● customer first focus;

● ethics, respect and humility;

● excellence and a willingness to learn;

● meritocracy, discipline and an execution mindset; and

● cost focus, with a school owner's mindset.

[**Table of Contents**](#TOC)

#### Technology
We believe that the use of technology is fundamental to achieving our goal of placing each student at the center of the educational experience. In our view, technology is a mean to delivering content through several formats and devices, creating a connection between each student and our common curriculum through a unique and comprehensive pedagogical approach.

To implement our vision, we've redesigned our structure, creating ArcoTech, a centralized tech unit responsible for integrating our user experience¸ maximizing the value of our products and reducing the time spent with repeated demands. The revamp of our technological backbone will allow for an easy plug-and-play structure for specifics products to all Arco brands - respecting their individuality and value proposition.

Our application programming interfaces, or APIs, provide a standardized way to provision, manage, engage, and deliver content to students, faculty and administrators. The APIs manage authentication and access for our entire technology stack and is designed to manage and interface with new technologies as they are introduced.

All our APIs, applications, and application components are designed from the ground up to produce significant, readable and interpretable data. Log monitoring allows us to proactively identify and mitigate potential capacity, performance, and security issues, while advanced analytics on student usage data provides the company with powerful insights to evaluate course content, communicate new technology releases, further personalize student's learning, and improve user experience and engagement.

Our products help (i) schools to create and manage their classes more efficiently; (ii) teachers to easily transpose their content into the platform, access thousands of questions, schedule classes and keep up with their student's development; and (iii) families to be closer to their children's performance through the usage of easy-to-use communication tools.

Our team is comprised of software engineers, product managers, user experience and user interface designers, data scientists and digital content developers, who are responsible for envisioning and creating the ideal digital presentation of our materials within our platform, bringing the work of our pedagogical and content teams to life.

Following the best frameworks in digital product development, we offer a buy-and-build solution from the customer standpoint, as users and customers can influence product evolution and participate in early stages of new-product conception.

The main drivers of our technology strategy are:

● Connectivity—connecting content and stakeholders in a seamless way;

● Omni-channel—full access to our content, anywhere, anytime, across devices;

● Empowerment—ability to identify individual needs and build a personalized learning experience;

● User Centered—intuitive design so users can quickly adapt and fully use features to their advantage;

● Management—data and analytics to support educators' decision-making; and

● Data Analytics—monitor and assess student performance, engagement, and the impact of our solutions.

#### What Sets Us Apart
We believe that we have the following business strengths that allow us to disrupt the private K-12 education market:

[**Table of Contents**](#TOC)

#### Disruptive approach to traditional school model
Instead of simply delivering content as a product through textbooks, we provide an education solution through a technology-based platform. We believe that our platform is cutting-edge, modern, dynamic and client oriented. We offer a multi-channel experience, combining proprietary content and software that would otherwise require the purchase of multiple, non-integrated solutions.

According to internal studies, we believe that the parents of students enrolled at our partner schools enjoy significant savings since our content solutions are less expensive than a traditional collection of textbooks, mainly because we can avoid incremental costs associated with a traditional retail distribution chain by primarily selling directly to our partner schools, as well as certain incremental costs relating to content production. In contrast, the sale of traditional textbooks often requires publishers to pay authors' royalties for each book sold, and traditional textbooks are frequently marketed as penned by specific authors, each of which generally entails higher total royalty costs, whereas we generally acquire rights to content from a large pool of available authors, without variable payments relating to royalties. Furthermore, we deliver a supplemental revenue stream for our partner schools.

As of December 31, 2022, partner schools charged parents an incremental markup on our wholesale per student prices.

#### Strong combination of content development team and technology to develop a best-in-class learning experience
As of December 31, 2022, we had a dedicated team of 792 technology and content development employees focused on developing and improving our Core Curriculum and Supplemental Solutions materials. They achieve this by leveraging feedback from our (i) highly qualified base of experienced educational authors in Brazil on the quality of materials we produce, and (ii) network of partner schools and teachers on the impact of our materials on student performance. The advanced state of our platform reflects a process of evolution spanning over a decade, making it difficult to replicate.

#### Widespread positive customer satisfaction and strong academic outcomes
Our customer satisfaction is driven by our ability to meaningfully improve the performance of our partner schools' enrolled students on the ENEM and universities admissions, a prerequisite for entrance into almost all higher education undergraduate institutions in Brazil. According to the 2023 university admission data published through SISU:

● 2,399 students within our partner school base have been accepted in the first place of their respective majors (a 59% increase when compared to 1,513 students in 2022, considering the same solutions);

● 11,114 students within our partner school base were accepted in top 10 positions of their respective majors (a 53% increase when compared to 7,242 students in 2022, considering the same solutions).

#### Strong brand equity and aligned incentives resulting in high retention rates
We prioritize quality by employing a "white glove" service model across our business, with clear financial incentives (in the form of bonuses) to our sales force that drive long-term relationships with our partner schools. Educational performance is one of the main drivers of school growth, and the success of our partner schools is a critical part of our value proposition. Due to the quality of our academic outcomes, we rarely lose clients. In addition, we have historically been highly effective in increasing contract values, achieving an annual retention rate of 91% in 2022, 93% in 2021 and 93% in 2020.

#### Attractive financial model with a high level of visibility and predictability
We have cash flow visibility given our long-term contracts with partner schools. Initial contract terms generally average three years, with high switching costs resulting in a customer churn of approximately 9% in 2022. In addition, we benefit from increasing enrollments across partner schools as our relationships mature and deployments increase, leading to revenue growth and increased operating margins, which contribute to the predictability of our business.

[**Table of Contents**](#TOC)

#### Founder-led and experienced management, innovation-driven culture
Our culture flows from our founder and CEO's family, who have specialized in education for over 50 years. Our founder and CEO, Mr. Ari de Sá Cavalcante Neto, has brought his family's successful school formula to scale by creating a leading educational platform. We strive to innovate and instill in our professionals a passion for serving all our stakeholders and seeking impactful next-generation solutions for private K-12 education.

As of December 31, 2022, the average age of our employees was 32.9 and 58% of our employees were women. Also, we offer a long-term incentive plan for key employees and apply meritocratic methods to engage them, recognize their value and maintain their motivation.

#### Our Growth Strategies
We aim to continue driving rapid, profitable growth and to generate greater shareholder value by implementing the following strategic initiatives:

#### Deepen relationships with our existing customer base
We intend to increase student enrollments within our existing partner schools at a minimum marginal cost as we see major opportunities for increased penetration through:

● increasing the number of class years that adopt our Core Curriculum at each partner school. As of March 30, 2023, our upselling potential would increase our student enrollments by 36%; and

● cross-selling our Supplemental Solutions to currently enrolled class years at our partner schools. As of March 30, 2023, only 18% of our client base used both our Core Curriculum and at least one Supplemental Solution, thus representing a cross-sell opportunity of over 1.4 million students.

#### Expand our partner school base
The private education sector in Brazil is very fragmented, with no relevant concentration in one or few providers. As Arco solutions penetrate this market and the performance of partner schools using our educational platform becomes more widespread and widely known, our sales efforts will benefit from the referrals generated by current school base.

#### Add new Supplemental Solutions
We consistently review potential opportunities to provide additional educational solutions that we may integrate into our Supplemental Solutions. We plan to enforce a disciplined approach to growth by using market validation techniques to assess the likelihood of our partner schools adopting our solutions, as well as their potential spending. We will also aim to ensure that any new vertical fits within our proven business strategy, through a careful assessment of available alternatives, such as the number and size of potential adjacent market opportunities, and their relative risk and return.

#### Continue to innovate and extend our technological leadership
Innovation is a cornerstone of our culture. As such, we employ significant efforts and resources to ensure the constant development and improvement of our portfolio of solutions. We have also invested in a select group of education technology startups to bring new ideas and solutions into our ecosystem. These initiatives have helped us identify new business potential to enhance our overall growth prospects, such as education technological features (WPensar, EEM, Studos and Eduqo), supplemental instruction content (International School, PES, NAV, Pleno, Escola da Inteligência, PGS and Coleção Mentes), digital-native content platform (Geekie), B2C online test prep solution (Me Salva!), and life-long learning platform connecting employees of companies across Brazil to free and discounted courses (Edupass).

[**Table of Contents**](#TOC)

We intend to increase the functionality of our platform and continue our investment in the development and acquisition of new applications that extend our technological leadership. We also intend to continue to improve and update our print and digital content based on the real-time feedback we receive from our partner schools.

#### Continue to pursue M&A opportunities
We plan to continue pursuing acquisitions that are complementary to, or that will help us diversify, our business. We intend to maintain a disciplined approach towards evaluating possible targets and integrating acquisitions into our business model. Our preferred acquisition targets are core or supplemental educational platform providers that engage in delivering high quality K-12 educational content through software-based platforms pursuant to B2B2C and B2C business models. We are currently evaluating possible acquisition opportunities and submit non-binding proposals from time to time.

We believe that we have developed a strong capability and track record of identifying, negotiating, and integrating acquisitions. Moreover, we have developed a systematic model that enables us to integrate our acquired businesses in a timely and efficient manner. Since 2011, we have successfully acquired or invested in 23solutions. Our acquisition strategy is focused on expanding our operations into new regions within Brazil and adding new products and technologies to accelerate our pace of innovation and broaden our footprint.

We have already executed several strategic transactions since our initial public offering. These acquisitions have a strong fit with our business and have been executed based on three main pillars: (i) boost growth, accelerating the expansion of our partner school base; (ii) increase cross-sell opportunities, extending our product offering; and (iii) enhance the client experience, adding value-add tech features. See "Item 4. Information on the Company—A. History and development of the company—Acquisitions and Investments."

#### Marketing and Sales
Our platform has evolved into a complex solution. The adoption of our platform by partner schools requires us to first build trust and confidence in our solutions, which can only be achieved by engaging them with our solutions and demonstrating a proven track record of success and quality, while constantly monitoring client satisfaction and feedback.

We have a non-traditional sales approach, which is structured around a practice we refer to as "Educational Consulting," which reflects both our core value of ensuring that education is our first priority, as well as the unique sales dynamics associated with our industry.

We have a lead time (which we define as the period from the moment of first contact to the execution of a contract) for the acquisition of new partner schools, and we typically enter contracts with new partner schools within one year from the moment of first contact, which requires a series of interactions and constant contact, to build a trust-based relationship with target and partner schools. Our sales strategy is based on creating touch points to highlight the quality of our solutions. We aim to achieve this with dedicated sessions for experimenting and testing with our platform. We also hold several specialized events aimed at target and partner schools, product journeys and guided visits to our units, and participate in industry fairs.

The success of our sales process requires uniquely qualified professionals, who must not only have an academic background, but are also sales oriented. We invest a significant amount of time and resources to recruit and train our sales force, averaging approximately 150 hours of training per year per person. After the initial training and exposure to our Educational Consulting environment, each professional begins working by shadowing an experienced consultant. It takes approximately a year of shadowing before each new professional can work individually on our behalf. In 2022, we had over 5,736 applicants for our consultant positions, and as of December 31, 2022, we employed more than 577 sales and marketing professionals. Our consultants' incentives are also aligned with our long-term goals and are tied to our profitability, as a significant portion of their annual compensation is variable and is paid out to them annually in the form of a bonus provided certain targets are met.

[**Table of Contents**](#TOC)

To improve and optimize our partner school acquisition process, we structured a market intelligence division, which focuses on mapping and segmenting our target markets to support and focus our sales strategies, as well as providing our sales consultants with industry knowledge and high-level market analysis and insights. Our market intelligence division has access to a significant volume of data, is continuously undertaking industry research and analysis and receives regular feedback from, and is in regular contact with, our consultants deployed in the field.

Additionally, we promote specialized events that are aimed to retain current partner schools. The most relevant event is Positivo's Course Program that provides teacher's training, workshops of recent trends in education and lectures from highly specialized and trained pedagogical professionals. In 2022, the Course Program reached 10,704 teachers.

In addition, we work in conjunction with a branding agency, which assists us in developing and strengthening our brands, increasing their national awareness, and building our institutional image. Our brand portfolio is structured to reflect our value proposition and leverage our marketing and sales strategy. A study conducted by *Expertise* as of July 2021 showed that the Positivo brand is the most recognizable among parents, teachers, and school events.

Furthermore, we have a loyalty program aimed at strengthening the relationship with partner schools and increasing the length of the contract. The loyalty program allows SPE to offer more personalized consulting services from our pedagogical experts, literature materials to complement the school's curriculum, cooperative media, and other products or services, to increase a contract's profitability.

#### Our Customer Service and Support
We believe that the best way to ensure the loyalty of our customers is to maintain a healthy, long-term relationship with our partner schools. We aim to achieve this through our customer engagement and support service, which supports partner schools in the implementation and integration of our educational solutions into their systems, as well as help them identify and achieve their pedagogical, business and management objectives, including legal, finance and marketing. Our customer service and support come in a variety of forms such as on-site visits, remote assistance, workshops, and events for partner schools. We assign independent and dedicated client-centric customer support teams to each of our solutions. Customer service and support is comprised of two departments which are focused on developing partner school relationships and are available to address any post-implementation issues that may arise: (1) pedagogical consulting, and (2) customer service:

#### Pedagogical Consulting
Our pedagogical consulting department is responsible for the pedagogical supervision and educational development of our partner schools. It aims to ensure that our educational platform is being used efficiently, and to actively assist our partner schools in improving the learning experience of their students and helping them develop the necessary skills inside and outside the classroom. It also leverages a dedicated management team to train and support our partner schools in maximizing their supplemental revenue streams.

Our pedagogical consulting team activities with partner schools include:

● implementing pedagogical methodologies in connection with our educational platform and associated educational materials, making pedagogical recommendations, understanding school communities, and coordinating lesson planning;

● periodic in-person meetings and coordinated site visits to evaluate the educational process, assisting partner school owners and faculty members to develop learning and interaction projects through the use of educational media content and new technologies, and conducting lectures for parents and students;

● continuous online or on-site training for teachers and school coordinators; and

● developing educational evaluation models tailored to each partner school's profile and needs, and training school owners and managers to use the school owner/manager specific features of our educational platform.

[**Table of Contents**](#TOC)

#### Customer Support
Our customer support department provides day-to-day customer and administrative support to our partner schools in connection with our educational platform by e-mail and/or by telephone. Our customer support department interacts with our pedagogical consulting department when necessary to minimize the risk of miscommunication and ensure a unified approach to customer satisfaction.

#### Our Geographic Presence
We believe our platform can be adopted by virtually any private K-12 school in Brazil. We believe that our product offering addresses Core and Supplemental curriculum needs for all Brazilian schools. As of March 30, 2023, our network consisted of 8,071 unique partner schools and 2,629,674 Number of Enrolled Students across all Brazilian states and in 1,649 cities, comprising students from kindergarten to high school. Our national presence has consistently expanded over the last five years, through both organic and non-organic growth and our largest client accounted for only 0.5% of our ACV Bookings.

#### Our Clients
We provide a complete pedagogical system with technology-enabled features to deliver educational content to K-12 schools in Brazil. Our turnkey curriculum solutions provide educational content in both printed and digital formats delivered through our platform to improve the learning process. Our network as of March 30, 2023, consisted of 8,071 partner schools. Our partner school base is highly diversified, which reduces our dependence on a concentrated number of large clients. Our 10 largest clients represented only 3.1%, 3.4% and 2.6% of our Delivered ACV Bookings in 2022, 2021 and 2020, respectively. Even though our partner schools pay for our solutions, we view students, parents, teachers, school management and teachers as our customers.

#### Our Competition
We compete with traditional publishers and textbook providers, other providers of core curriculum solutions, as well as with online education platforms. Factors influencing competition in this industry may include price, overall education experience and track record, industry experience and reputation, content quality, availability of technology, faculty, facilities, location and program offerings, among others.

Most traditional publishers and textbook providers are typically focused exclusively on physical textbooks. They do not produce their own content, do not update their content frequently, and do not have developed digital platforms. Furthermore, we believe that traditional publishers and textbook providers whose strategy it is to develop education solutions similar to ours do not possess the content development expertise, brand awareness, or the track record to sell such solutions directly to schools.

Other core curriculum solutions providers offer primarily printed content and a limited amount of digital content. Other online platforms that offer education solutions through digital channels face difficulties to efficiently integrate solutions for schools, parents, students, and teachers. We believe our proprietary content is engaging to students, teachers, and parents, as illustrated by our ability to persuade schools to switch from other products to our products.

We seek to differentiate ourselves from our competitors primarily on the basis of our simple, integrated and personalized educational platform. We believe the following factors are critical to success in the private K-12 education in Brazil:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) level of a solution's effectiveness, personalization, engagement and enjoyment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) quality of the user experience and customer service;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) breadth and depth of features and functionalities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) brand recognition and academic outcomes; and

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(5) overall cost of education solutions.

#### Seasonality
Our revenues and operating results normally fluctuate because of seasonal variations in our business. For further information on seasonal variations in our business, please see "Item 5. Operating and Financial Review and Prospects—A. Operating results—Revenue Recognition and Seasonality."

**ESG at Arco**

Arco was born with the mission to transform the way students learn by delivering high quality education at scale. We believe that our mission and the social impact we aim to achieve will only be delivered if we are able to engage our stakeholders and manage properly our Environmental, Social and Governance risks.

During 2021, we conducted an ESG materiality process in consultation with a specialized ESG firm, which identified the material topics for our company and prioritized them through interviews and a survey with over 200 stakeholders, including employees, investors, sell-side analyst, suppliers and Non-Governmental Organizations supported by the Arco Institute. We also established an ESG Advisory Group constituted by Arco's CHRO, COO, CFO and legal department, which supported the establishment of material topics, the prioritization according to the business impact, the engagement of the whole team and communication with different areas of the Company.

As a result, we have established three ESG pillars:

***Promote the Impact on Education***

To guarantee Arco's continuous evolution, we need to keep delivering and improving the quality of our content and technology, be able to grow in scale and increase the accessibility of our products and services.

Our progress in those topics is quantified by our ability to:

● Develop educational tools that engage our students and improve the performance of our partner schools in the main university's admissions exams;

● Build long-lasting and reliable relationships with our customers; and

● Increase the access to our products to different socioeconomic classes. We have progressed in this topic by providing educational solutions with different average tickets to schools, therefore reaching schools with a diverse tuition profile, and also through Arco Institute, our social initiative that supports public schools' students, delivering educational solutions and institutional assistance to different educational organizations.

In our latest ESG report, we have quantified those aspects through different metrics, such as NPS, retention rates and number of ENEM approvals, among others.

***Focus on our people***

Arco is a company built upon the belief that our people is our strength. We are constantly looking for highly talented and diverse people, aligned with our values and engaged on delivering our purpose. We work to maintain a sense of ownership and engagement by investing in the development and continuous evolution of our people, creating a diverse environment in which people belong and can prosper.

[**Table of Contents**](#TOC)

To measure the success of our people-centric culture, our teams' perception regarding Arco and its career opportunities, we track:

● The voluntary turnover of our talents, developing strategies to understand the main reasons and to reduce it;

● The evolution of our *Employees' Net Promoter Score* (eNPS), strengthening our culture by building rituals, moments with the leadership and development opportunities; and

● Metrics on diversity (regarding disability, gender and ethnical aspects), by spreading educational contents, raising awareness about the theme and creating learning trails for the leadership.

***Strong and sustainable structure***

This pillar can be divided in two main parts. The first part, relating to our corporate governance and stakeholders' alignment, is ensured by:

● Maintaining a solid and reliable Code of Ethics, which guides the work of all employees and partners according to the same principles,

● An independent and confidential Ethics Channel, where people feel safe to make their complaints;

● An alignment of our Executives compensation with our main business goals;

● Building up teams with diverse and independent perspectives on our business, both on a Board and Executive level; and

● Guaranteeing the data security of our employees, partner schools and students by using attested security frameworks.

For further information on Corporate Governance, please see Item 16.G of this annual report, as well as the main indicators on our ESG Report.

With respect to the second part, regarding the sustainability of our supply chain, we work constantly to reduce our impact in the environment by:

● Using sustainability criteria to choose our printing suppliers; and

● Following the path of our paper, to make sure it is correctly recycled or covered by take-back programs.

We have also established goals to constantly evolve our ESG practices. For further information, please see our 2022 ESG Report published on our IR website (https://investor.arcoplatform.com/esg/).

#### Regulatory Overview
The Brazilian constitution establishes education as a right of all citizens, the provision of which is a duty of the state and the family. Accordingly, the government is required to provide all Brazilian citizens with access to free primary education that requires compulsory attendance. Private investment in education is permitted so long as entities providing education services comply with the applicable rules and regulations.

[**Table of Contents**](#TOC)

The Brazilian education system is organized as a cooperation regime among federal, state, and municipal governments. The federal government is required to organize and coordinate the federal education system in order to guarantee equal opportunity and quality of education throughout Brazil, as well as regulating higher education activities. Brazilian states and the Brazilian Federal District are required to focus on primary and secondary education, while municipalities are responsible for providing preschool and primary education, and each is responsible for establishing and implementing the relevant rules and regulations for each educational stage the subject of its focus, including monitoring and evaluation, and the issuance of all relevant authorizations, recognitions, and qualifications for each such educational stage.

Law No. 9,394/1996, or National Education Guidelines Law *(Lei de Diretrizes e Bases da Educação Nacional*), or LDB, establishes the guidelines for the provision of education services in Brazil and sets forth the federal government's duty to: (1) coordinate the national education system; (2) prepare the National Education Plan; (3) provide financial assistance to the states, the Federal District and municipalities; and (4) define, in cooperation with other federal entities, the responsibilities and guidelines for primary and secondary education.

In addition, the federal government, through Law No. 13,005 of June 25, 2014, implemented the National Education Plan (*Plano Nacional de Educação*), or PNE, valid for ten years from the date of its enactment. The PNE established objectives for primary and secondary education that must be met by the Brazilian federal system. Some of these objectives are: (1) the universalization of preschool education, with a target to enroll at least 50% of all children up to three years of age in schools by 2024; (2) the universalization of primary education, with a target to enroll at least 95% of children between the ages of six and fourteen in schools by 2024; (3) the universalization of secondary education, with a target to enroll at least 85% of adolescents between the ages of 15 and 17 in schools by 2024; (4) to ensure that all children learn the Portuguese alphabet by the third year of primary education; (5) to make available full-time education in at least 50% of public schools; (6) to improve the quality of primary education as evaluated by the IDEB; (7) to ensure that all students are literate by the time they are 15 years old; (8) to make available at 25% of primary and secondary education to young adults and adults; and (9) to increase enrollment in professional studies to three times the current enrollment rate. Accordingly, each of the federal, state and municipal governments was required to prepare a ten-year education plan and establish policies, guidelines and objectives applicable to the segment of the Brazilian education system over which it is responsible. In addition, these objectives act as guidelines for the private education sector.

#### Primary and Secondary Education
Primary and secondary education in Brazil is equivalent to K-12 education in the United States, and consists of elementary school, junior high and high school, which are regulated by the LDB and the PNE.

The LDB regulates a nationwide, common core curriculum, the number of teaching hours, the minimum classroom attendance and grade advancement. States, municipalities, and educational institutions can pass rules and regulations according to specific regional and local requirements, such as differences in curricula and calendar, grade advancement and issuance of academic documentation for primary and secondary education students.

The PNE establishes ten-year targets for all the levels and stages of education, mandating that states and municipalities create and establish similar plans compatible with such national targets. It is incumbent upon the Primary and Secondary Education Secretariat (Secretaria de Educação Básica), or SEB, under the supervision of the MEC, to monitor compliance with the PNE by states and municipalities. This inspection and monitoring include guidance and rules for assessing the primary and secondary education stages.

Under the federal constitution and the LDB, access to primary and secondary education is a right of all children from the ages of four to 17. Following amendments to Law No. 11,274 on February 6, 2006, the duration of primary and secondary education was extended from a period of eight years to a period of nine years. Among the purposes of primary education are: (1) development of the capacity to learn, including basic abilities in reading, writing and arithmetic; (2) comprehension of the natural and social environment, the political system, technology, arts and social values; (3) development of the capacity to acquire new knowledge and abilities and the formation of attitudes and values; and (4) strengthening family ties, social cohesion and mutual tolerance. Assessment of primary education is coordinated by the state legislation of each individual state, on a case-by-case basis.

[**Table of Contents**](#TOC)

Secondary education is designed to fulfill the government's duty to progressively complete the formation of the citizen, seeking universalization of scope and coverage. Secondary education is conducted for a period of not less than three years and seeks: (1) the consolidation and deepening of the knowledge acquired in primary education; (2) the basic preparation of the person being educated for work and to be able to adapt within the labor market or pursue further education; (3) the improvement of the student as a person, including ethical formation and the development of intellectual autonomy and critical thinking; and (4) the comprehension of the scientific and technological bases of the productive processes, relating theory to practice in each discipline. Assessment of secondary education is conducted on a national scale and coordinated by the MEC.

Law No. 13,415/2017 amended the LDB and changed the structure of secondary education, increasing the academic courses load per year and establishing a new curricular structure that comprises a specific BNCC. Following this normative change, Ruling No. 1,210/2018 approved the new National Curriculum Guidelines (*Diretrizes Nacionais Curriculares* or DCN) for High School, which is known as the "New High School" (*Novo Ensino Médio*).

Gradual implementation of this model began in 2022 (with implementation expected to be concluded by 2024) and one of its main innovations is the establishment of training itineraries (*itinerários formativos*). The structure of training itineraries is established by the DCN for High School, and characterizes them as a set of subjects, projects, workshops, study centers, among other situations, that students will be able to choose according to their areas of interest as well as life and career projects and aspirations. The training itineraries focus on deepening the study of a specific field of knowledge (Mathematics and its Technologies, Languages and its Technologies, Natural Sciences and its Technologies and Applied Human and Social Sciences) or technical and professional training (FTP) chosen by the student and each school must offer at least one itinerary, while each municipality must offer at least two itineraries, in order to ensure options for students.

#### Regulatory Bodies
The main regulatory bodies of the Brazilian education system are:

● the MEC;

● the National Education and Research Institute (Instituto Nacional de Estudos e Pesquisas Educacionais Anísio Teixeira), or INEP;

● the CNE;

● the CEB;

● the Higher Education Board (*Câmara de Educação Superior*), or CES;

● State and Municipal Secretariats (Secretarias Estaduais de Educação and Secretarias Municipais de Educação, respectively); and

● State and Municipal Councils of Education (*Conselhos Estaduais de Educação* and *Conselhos Municipais de Educação*, respectively).

The MEC is Brazil's highest governmental body for education. It formulates and evaluates Brazilian national education policy, ensuring the quality of education and compliance with education regulations. The INEP is an independent related federal entity responsible for evaluating educational institutions in Brazil, as well as conducting research to provide a reliable database for public use.

The MEC is assisted by the CNE, which is the entity with regulatory power and deliberative authority to ensure national education improvement. The CNE is comprised of the CEB, which is the federal agency responsible for the regulation of the K-12 education system, and the CES, which is the federal agency responsible for the post-secondary education system. Both regulatory bodies are composed of 12 members appointed by the President of Brazil.

[**Table of Contents**](#TOC)

States and municipalities are responsible for regulating K-12 education. State Secretaries of Education (*Secretarias Estaduais de Educação*) are assisted by the State Councils of Education (*Conselhos Estaduais de Educação*) and are the main regulatory bodies for primary and secondary school education. The Municipal Secretaries of Education (*Secretarias Municipais de Educação*) are assisted by the Municipal Councils of Education (*Conselhos Municipais de Educação*) and are the main regulatory bodies of preschool education.

The LDB grants power to states and municipalities to authorize, accredit and supervise primary and secondary education institutions. This is achieved through each governmental entity's respective Department of Education.

#### Regulations Applicable to the Company's Activities
The Company is not directly regulated by the MEC nor any other regulatory agency. However, our educational platform and related educational materials seek to comply with the LDB and the guidelines established by the BNCC. In addition, our partner schools are K-12 education providers and are directly regulated by the educational authorities explained above and must comply with their regulations.

The BNCC is a set of guidelines that provides a curriculum specifying the core skills and knowledge required to be taught as part of primary and secondary education in Brazil and each school has the autonomy to elaborate or adapt their curricula and pedagogical projects according to such guidelines. The BNCC guidelines were established following overall poor student performance levels achieved while the predecessor education guidelines were in effect. Several indicators suggest that the predecessor guidelines were failing in many ways, leading the MEC to initiate discussions relating to a new method based upon a comparison between Brazil and other countries' results, which formed the basis for developing the BNCC. The LDB and the BNCC establish what subject matters shall be taught for each level of education (early childhood education, primary education and secondary education), and we are constantly working on our content to ensure that they comply with these guidelines, as well as with our partner schools' demands.

As provided by the LDB and the BNCC, early childhood education should enable children to live in society, to play, to participate, to explore, to express themselves, and to know themselves. Primary education, in turn, shall offer the following subject matters: (i) Portuguese; (ii) Arts; (iii) Mathematics; (iv) Geography; (v) History; (vi) Religious Studies; (vii) English; (viii) Science and (ix) Physical Education. Also, according to the current BNCC, approved by Ruling No. 1,210, 2018, secondary education shall offer curricula covering the following subjects (i) Portuguese; (ii) Arts; (iii) Mathematics; (iv) Geography; (v) History; (vi) Physics; (vii) Chemistry; (viii) Biology; (ix) English, (x) Science, (xi) Sociology; (xii) Philosophy; and (xiii) Physical Education. As our partner schools are private and have the autonomy to establish their pedagogical projects, there are no other guidelines relevant to the materials provided.

While following the BNCC is still required of every school in the country, there are opportunities to provide content solutions and after-school solutions to improve and adapt to the new status quo in Brazil's education market.

#### Syndicates
Under Brazilian labor law, all companies and employees are represented by unions, regardless of whether they are unionized. The unions representing the companies and the employees negotiate the terms of collective bargaining agreements on an annual basis or every two years. Employers are required to grant employees all the rights and working conditions set forth in the collective bargaining agreement, regardless of whether the employee is unionized or not. The employees who choose to be unionized are required to contribute to the workers' syndicate that represents their sector. The syndicate contribution is deducted once a year by the employer directly from such employee's payroll in an amount equal to one working day's salary, subject to the express authorization of such employee.

#### Data Protection
Cybersecurity has become a top priority for regulators around the world, and in Brazil it is no different. Having come into effect in September 2020, the Brazilian Data Protection Law (Law No. 13,709/18, *Lei Geral de Proteção de Dados*), or LGPD, is a comprehensive personal data protection law establishing general principles and obligations that apply across multiple economic sectors and contractual relationships.

The LGPD applies to individuals or legal entities, private or government entities, who processes personal data in Brazil or collects personal data in Brazil or, further, when the processing activities have the purpose of offering or supplying goods or services to data subjects located in Brazil. The LGPD establishes detailed rules for processing personal data, which includes the collection, use, transfer and storage of personal data and will affect all economic sectors, including the relationship between clients and suppliers of goods and services, employees and employers and other relationships in which personal data is collected, whether in a digital or physical environment.

Pursuant to the LGPD, security breaches that may result in significant risk or damage to personal data must be reported to the National Data Protection Authority (*Autoridade Nacional de Proteção de Dados*), or ANPD, the data protection regulatory body, within a reasonable time period. The notice to the ANPD must include: (a) a description of the nature of the personal data affected by the breach; (b) the affected data subjects; (c) the technical and security measures adopted; (d) the risks related to the breach; (e) the reasons for any delays in reporting the breach, if applicable; and (f) the measures adopted to revert or mitigate the effects of the damage caused by the breach. Moreover, the ANPD could establish other obligations related to data protection that are not described above.

LGPD allows private right to petition, so we are subject to individual claims for violations of LGPD. The penalties and fines for non-compliance with the LGPD include: (1) warnings, with the imposition of a deadline for the adoption of corrective measures; (2) fines, up to a maximum amount of 2% of the company or group turnover in Brazil, limited to R$50.0 million per violation; (3) disclosure of the violation; (4) the restriction of access to or deletion of the personal data to which the violation relates (5) in case of repetition of the violation, temporary suspension of the database or of data processing activities.

We started implementing the LGPD requirements in January 2020, adapting our websites, e-commerce platforms and systems and processes to the new legislation and creating new privacy policies and warnings. We are developing our LGPD program taking into account the changes in cultural and consumer attitudes towards the protection of personal data law and to comply with any new regulations, creating more training for our employees and clients to promote conscience and promote conscience and change of data analysis and treatment. In 2021 we mapped and identified the risks involved with our business, as we process data on children and adolescents, in order to monitor and control sensitive points to promote greater safety, law enforcement and risk reduction. This data protection impact report is a report of the controller's documentation that contains the description of the processes of processing personal data that may generate risks to civil liberties and fundamental rights, as well as measures, safeguards and risk mitigation mechanisms. In addition, our Privacy and Cybersecurity Committee is composed of our DPO and other senior leadership members, bringing diverse backgrounds to the establishment of related LGPD and cybersecurity practices and measures, as well as readjustments and quality preservation initiatives.

#### ITEM 4A. UNRESOLVED STAFF COMMENTS
Not applicable.

#### ITEM 5. OPERATING AND FINANCIAL REVIEW AND PROSPECTS
*The following discussion of our financial condition and results of operations should be read in conjunction with our Consolidated Financial Statements and the notes thereto. The following discussion contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those discussed in the forward-looking statements because of various factors, including those set forth in "Item 3. Key Information—D. Risk factors."*

A. Operating Results

We provide a complete pedagogical system with technology-enabled features to deliver educational content to private schools in Brazil.

We founded our company with the aim of creating high quality products that simplify learning and make the education process more efficient. Traditionally, school administrators required a multitude of vendors for content development, training, commercializing, and managing K-12 education. Simultaneously, students acquired educational content through textbooks from various publishers across retail channels. Our platform aims to replace this multitude of third-party educational providers with a streamlined, one-stop solution that delivers high quality education at scale.

We believe the success of our platform, together with the quality of our client base and the popularity of our brand, has driven our significant growth, allowing us to expand our footprint quickly and efficiently in Brazil.

We provide a complete suite of turnkey curriculum solutions and technology-enabled features to help our students, teachers, partner schools and parents, targeting our students' educational success. Our turnkey educational platform solutions consist of core K-12 curricula, as well as supplemental instructional content currently focused on English as a second language.

As of March 30, 2023, our Core Curriculum and Supplemental B2B2C Content Solutions had 8,071 unique partner schools. These schools are spread across 1,649 cities located across all the states of Brazil. Our partner schools base is highly diversified, which reduces our dependence on major accounts.

#### Our Growth
![Graphic](arce-20221231x20f009.jpg)

Our revenue growth has been driven by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·  ***Expansion of our partner school base:*** The increase in the number of partner schools using our educational platform. Through a sophisticated sales process with our highly skilled sales team, we build relationships with partner schools and plant seeds for new features and products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•***  ***Deepening of relationships with our existing customer base:*** The increase in the number of enrolled students we serve in our partner schools, through (i) the increase in the number of class years that adopt our Core Curriculum solutions (upselling), and (ii) cross-selling our Supplemental Solutions and services.

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•***  ***Price increases:*** The annual adjustments of our contract fees, in line with our price-setting policies which are usually above published inflation indices, to account for changes in our cost and expenses' structure and for improvements in our platform.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•***  ***M&A:*** The acquisition of complementary businesses has helped us expand our operations regionally and nationally and add new products and technologies. This allows us to become a one-stop shop platform, which we believe further strengthens our stickiness and improves our value proposition.

The strength of our partner school base and our ability to expand sales are demonstrated in the increasing portion of our ACV Bookings from existing clients and upsell in existing clients prior to the COVID-19 pandemic, represented in the chart below. During the 2020 and 2021 school years, our business was temporarily impacted by the non-recurring dropouts of students in partner schools, which normalized in 2022.

![Graphic](arce-20221231x20f010.jpg)

#### Revenue Recognition and Seasonality
Prior to the adoption of IFRS 15, revenue was recognized when the significant risks and rewards of ownership were transferred to the customer, recovery of the consideration was probable, the associated costs and possible return of educational content could be estimated reliably, there was no continuing management involvement with the educational content and the amount of revenue could be measured reliably. Upon the adoption of IFRS 15, revenue is recognized when the performance obligation is satisfied. We recognize our revenue when we deliver our content to our partner schools in printed format or via access to the content in our digital platform. The technology is provided solely to optimize the use of our educational content. Our printed materials can be used independently of the technology we provide, as the content of both our printed materials and online materials is substantially the same.

We generate substantially all our revenue from contracts that have an average term of three years, pursuant to which we provide educational content in printed and digital format to partner schools. Our revenue is driven by the number of enrolled students at each partner school using our solutions and the agreed price per student per year, all in accordance with the terms and conditions set forth in each contract. Each contract contemplates penalties ranging between 20% and 100% of the remaining total value of the contract in the event of termination, and the content already delivered by us through the termination date is not returned to us by the partner school.

Our partner schools pay us our fees directly and pass that cost on to their enrolled students' parents, who in turn are charged through a mandatory supplement to school tuition, in lieu of paying for textbooks from several vendors. Most of our partner schools charge parents an incremental markup from which we do not earn any additional revenue on top of our wholesale prices.

[**Table of Contents**](#TOC)

Pursuant to the terms of our contracts with our partner schools, they are required, by the end of November of each year, to provide us with an estimate of the number of enrolled students that will access our content in the next school year (which typically starts in February of the following year). Since we allow our partner schools to make small adjustments to their estimates to account for late admissions and dropouts, this number may fluctuate slightly until the end of March, when it becomes more accurate.

We typically deliver our Core Curriculum content four times each year in March, June, August and December and our Supplemental Solutions content twice each year in June and December, typically two to three months prior to the start of each school quarter. This allows our partner schools and their teachers to prepare classes in advance of each school quarter. Because we recognize revenue upon delivery of our educational content, our fourth quarter results reflect the growth in the number of our students from one school year to another. Consequently, we generally produce higher revenues in the fourth quarter of our fiscal year compared to the preceding quarters.

In addition, we bill partner schools and collect the sales we charge them in the first half of each academic collections year, generally resulting in a higher cash position in the first half of each fiscal year relative to the second half of each fiscal year.

Accordingly, we expect quarterly fluctuations in our revenues and operating results to continue. These fluctuations could result in volatility and adversely affect our liquidity and cash flows. As our business grows, these seasonal fluctuations may become more pronounced. As a result, we believe that sequential quarterly comparisons of our financial results may not provide an accurate assessment of our financial position.

A significant portion of our expenses is also seasonal. Due to the nature of our business cycle, we require significant working capital, typically in September and/or October of each year, to cover costs related to production and accumulation of inventory, selling and marketing expenses, and delivery of our teaching materials at the end of each fiscal year in preparation for the beginning of each school year. Therefore, such operating expenses are generally incurred in the period between September and December of each year.

#### Key Business Metrics
We review the following key metrics to evaluate our business, measure our performance, identify trends affecting our business, formulate business plans and make strategic decisions:

**Operating Data**

#### Enrolled Students
The number of enrolled students is the primary operational metric our management reviews for our B2B2C Core Curriculum and Supplemental Content Solutions. It represents the total number of students at our partner schools served by our platform during a given school year. Although our primary customers are the partner schools we attract to our base, our revenues are determined by the number of students enrolled in our partner schools. For purposes of calculating this metric and the total number of students, a student at a partner school that is enrolled in (and pays for) more than one of our solutions is counted as one student for each such solution. For example, a student at a partner school that is enrolled in (and pays for) one Core Solution and two Supplemental Content Solutions is counted as three students for purposes of calculating this metric.

We typically have high visibility of the number of students we will serve before the school year starts, typically by the end of November. Since we allow our partner schools to make small adjustments to their estimates to account for late admissions and early dropouts, this number may fluctuate slightly until the end of March in each year, when it becomes more accurate. Accordingly, we believe this metric is most accurately reflected as of the end of March of each year.

[**Table of Contents**](#TOC)

Following March 31 in a calendar year, our partner schools may experience additional admissions and/or dropouts up to September 30 of such year, which is the date on which the number of students for the year becomes final, or Final Number of Students. In years prior to the COVID-19 pandemic, the difference between the Number of Enrolled Students as of March 31 and the Final Number of Students as of September 30 was not material. However, during 2020 and 2021 and as result of the impacts of the COVID-19 pandemic, our partner schools experienced atypical dropout rates from March 31 to September 30, and our number of students decreased from Number of Enrolled Students of 1,362,141 as of March 31, 2020, to Final Number of Enrolled Students of 1,239,937 as of September 30, 2020, and from Number of Enrolled Students of 1,785,576 as of March 31, 2021, to Final Number of Students of 1,489,707 as of September 30, 2021. In 2022, there were no atypical dropouts, and trends reverted to pre pandemic levels.

#### ACV Bookings
ACV Bookings is an operating metric and represents our customers' commitment to pay for our solutions offerings. We believe they are a meaningful indicator of demand for our platform and the market's response to it. We define ACV Bookings as the revenue we would contractually expect to recognize in each school year pursuant to the terms of our contract, assuming no further additions or reductions in the number of enrolled students that will access our content in such school year. ACV Bookings is a non-accounting managerial operating metric and is not prepared in accordance with IFRS. We calculate ACV Bookings by multiplying the number of enrolled students with the average ticket per student per year, all in accordance with the terms of our contract with such partner school. For our B2B2C Core Curriculum and Supplemental Content Solutions, although our contracts with our partner schools are typically for three- year terms, we record one year of revenue under such contracts as ACV Bookings. For example, if a school enters into a three-year contract with us to provide our Core Curriculum solution to 100 students for a contractual fee of $100 per student per year, we record $10,000 as ACV Bookings, not $30,000.

For our B2B2C Core Curriculum and Supplemental Content Solutions, we measure our ACV Bookings monthly throughout the school year, starting in November of the preceding fiscal year. Pursuant to the terms of our contracts with our partner schools, they are required, by the end of November of each year, to provide us with an estimate of the number of enrolled students that will access our platform in the next school year. Since we allow our partner schools to make small adjustments to their estimates to account for late admissions and early dropouts, this number may fluctuate slightly until the end of March in each year, when it becomes more accurate. Accordingly, we believe this metric is most accurately reflected as of the end of March in each year, and in this annual report, we refer to our ACV Bookings we refer to our ACV Bookings as of March 30, 2023 and as of March 31, 2022, 2021 and 2020 as our ACV Bookings.

[**Table of Contents**](#TOC)

Following March 31 in a calendar year, our partner schools may experience additional admissions and/or dropouts up to September 30 of such year, explaining the difference between the ACV Bookings and the revenue recognized for such school year. In years prior to the COVID-19 pandemic, the difference between our ACV Bookings and the revenue recognized for the school year was not material, demonstrating the predictability of our business. However, during 2020 and 2021 and as result of the impacts of the COVID-19 pandemic, our partner schools experienced atypical dropout rates from March 31 to September 30, and the difference between our ACV Bookings and the revenue recognized for each school year was -4% and -9%, respectively. In the 2022 school year, our partner schools did not experience atypical dropouts and we recognized 100% of our ACV bookings for the year. Consequentially, the dynamics mentioned above also impacted the number of enrolled students in our partner schools.

#### Brazilian Macroeconomic Environment
We believe that our results of operations and financial performance are and will continue to be affected by the following macroeconomic trends and factors:

All our operations are located in Brazil. As a result, our revenues and profitability are affected by political and economic developments in Brazil and the effect that these factors have on the availability of credit, disposable income, employment rates and average wages in Brazil. Our operations, and the industry in general, are particularly sensitive to changes in economic conditions.

[**Table of Contents**](#TOC)

Brazil is the largest economy in Latin America, as measured by gross domestic product, or GDP. The following table shows data for real GDP, inflation and interest rates in Brazil and the U.S. dollar/real exchange rate at the dates and for the periods indicated.

 *Source*: FGV, IBGE, Central Bank and B3.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Inflation (IGP-M) is the general market price index measured by the FGV.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Inflation (IPCA) is a broad consumer price index measured by the IBGE.

&nbsp;&nbsp;&nbsp;&nbsp;(3) TJLP is the Brazilian long-term interest rate (average of monthly rates for the period).

&nbsp;&nbsp;&nbsp;&nbsp;(4) Refers to the average CDI rate during the corresponding period.

&nbsp;&nbsp;&nbsp;&nbsp;(5) Average of the exchange rate on each business day of the year.

&nbsp;&nbsp;&nbsp;&nbsp;(6) Comparing the US$ closing selling exchange rate as reported by the Central Bank at the end of the period's last day with the day immediately prior to the first day of the period discussed.

&nbsp;&nbsp;&nbsp;&nbsp;(7) Average unemployment rate for year as measured by the IBGE.

For the years ended December 31, 2022, 2021 and 2020, we have been able to offset all or most of the inflation effects by adjusting the contractual fees per student that we charge our partner schools above the IPCA rate. Our financial performance is also tied to fluctuations in interest rates, such as the CDI rate, because such fluctuations affect the value of our financial investments.

#### Printer Costs; Raw Materials
We outsource the printing and binding of our educational materials. Printer costs are one of our principal costs; printer fees are impacted by changes in the price of paper, one of the principal raw materials required to produce our educational materials. The cost of paper is generally impacted by fluctuations in the U.S. dollar/real exchange rate, and is also impacted by inflation, but not necessarily linked to a specific inflation index. Such changes in prices are reflected as inflation adjustments in the fees charged by our third-party printers, which produce our printed materials. To the extent we cannot offset the impact of printer costs by adjusting the contractual fees per student that we charge our partner schools, our margins may be negatively affected.

**Recent Accounting Pronouncements**

For a discussion on recent accounting pronouncements, see note 2.4 to our audited consolidated financial statements.

#### Components of Our Results of Operations
The following is a summary of the principal line items comprising our statements of income (loss).

[**Table of Contents**](#TOC)

#### Net revenue
We generate substantially all our revenue from contracts that have a standard term from one to five years, pursuant to which we provide educational content in printed and digital format to partner schools.

Our revenue is driven by the number of enrolled students at each partner school using our solutions and the agreed price per student per year, all in accordance with the terms and conditions set forth in each contract. We recognize our revenue when we make our content available to our partner schools in printed format or via access to our digital platform. Most of our Core Curriculum content is delivered in four times each year in March, June, August and December and most of our Supplemental Solutions content once each year from November to March, and the most representative Supplemental Solution content twice each year in June and December, usually two to three months prior to the start of each school quarter. This allows our partner schools and their teachers to prepare classes in advance of each school quarter.

#### Cost of Sales
Cost of sales primarily consists of expenses related to the production and delivery of our content and technology, which are mainly composed of printing costs, employee-related costs, and the purchase of long-term intellectual property assets such as educational content produced by third-party authors, as well as inventory write-off costs.

We intend to continue to invest additional resources in our content development and technology platform. The timing of these expenses will affect our cost of sales in the affected periods. Also, we may launch new products that require additional resources and can affect our cost of sales.

#### Expenses
We classify our operating expenses as selling expenses, general and administrative expenses, and other expenses. The largest component of our operating expenses is employee and labor-related expenses, which includes salaries and bonuses, employee benefit expenses and contractor costs. We allocate expenses such as information technology infrastructure costs related to our operations and rent and occupancy charges in each expense category based on employee headcount in that category.

● *Selling Expenses.* Selling expenses consist primarily of the personnel expenses of our sales and marketing and customer support employees, including commissions and incentives, travel and travel-related expenses, benefits, marketing programs, including lead generation, costs of our education-related conferences and other miscellaneous expenses, as well as intangible assets amortization expenses. We expect that our selling expenses will increase as we increase the size of our sales and marketing teams and potentially increase the number of conferences and events that we organize.

● *General and Administrative Expenses.* General and administrative expenses consist of personnel expenses and related expenses, including executive, finance, legal, human resources, recruiting, employee-related information technology, administrative personnel, payroll, and benefits. They also consist of expenses in connection with professional fees for external legal, accounting, and other consulting services, intangible assets amortization expenses, as well as other miscellaneous expenses. Going forward, we expect general and administrative expenses to increase on an absolute *real* basis but decrease as a percentage of total revenue as we continue to focus on processes, systems and controls that will enable our internal support functions to grow concurrently with the growth of our business.

We allocate share-based payment expense to general and administrative expenses. These share-based expenses represent granted restricted shares to selected employees we consider to be key executives. We recognize our share-based payments as an expense in the statement of income based on their fair value over the vesting period. These charges have been significant in the past, and we expect that they will increase as we hire more employees and seek to retain existing employees.

#### Other Income (Expenses), Net
Our other income (expenses), net, line item consists mainly of miscellaneous income and/or expense items.

[**Table of Contents**](#TOC)

#### Finance Result
Our finance result includes finance income and finance costs.

Finance income includes mainly income from cash equivalents and financial investments, foreign exchange gains, changes in fair value of derivative instruments and from business combinations. Finance costs consist mainly of interest on loans and financing, interest expense on liabilities related to business combinations and investments in associates, foreign exchange loss and changes in fair value of derivatives instruments, changes in accounts payable to selling shareholders, interest expenses in lease liabilities and other financial discounts.

#### Income Taxes
Income taxes include current and deferred income taxes. Deferred tax expenses are mainly related to tax losses carryforward, provisions for bonuses, inventories reserve, allowance for doubtful accounts, share-based compensation plan, intangible amortization and derivatives from acquisition of interests and business combinations.

*Net Revenue*

Net revenue for the year ended December 31, 2022 was R$1,775.4 million, an increase of R$543.3 million, or 44.1%, from R$1,232.1 million for the year ended December 31, 2021.

This increase was primarily attributable to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the positive impact of our organic growth through the addition of new partner schools and upsell within our solutions, which resulted in a 15% increase in the Number of Enrolled Students for 2023 at our partner schools to 2,629,674 as of March 30, 2023, from the Number of Enrolled Students of 2,279,025 as of March 31, 2022;

This increase was primarily attributable to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) in the fourth quarter of 2021, the positive impact of our organic growth through the addition of new partner schools and upsell within our solutions, which resulted in a 28% increase in the Number of Enrolled Students for 2022 at our partner schools to 2,279,025 as of March 31, 2022, from the Number of Enrolled Students of 1,785,576 as of March 31, 2021; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the addition of new solutions to the portfolio, such as Me Salva!, Eduqo, Edupass, COC and Dom Bosco, all acquired in 2021.

This increase was partially offset by the negative impact of student dropouts in our partner schools in the first three quarters of 2021, which led to a lower than expected revenue recognition for the period.

&nbsp;&nbsp;&nbsp;&nbsp;(11) Adjusted net income reflects the adjusted result of the business, excluding the effects of the special items described above. 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) Foreign exchange effects on cash and cash equivalents; (ii) share of loss of equity - accounted investees and (iii) Interest income (expenses) linked to a fixed rate (we will maintain the adjustment for Interest income (expenses) that refers to adjustments by fair value). 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.

#### Indebtedness
As of December 31, 2022, our total outstanding indebtedness was R$1,936.8 million.

On August 5, 2022, we issued R$1.2 billion in debentures through our wholly owned subsidiary, CBE, in a restricted placement efforts offering to institutional investors. The debentures bear interest at the CDI rate plus 2.3% per annum and mature on August 3, 2027. The principal will be amortized in three equal instalments payable on August 3, 2025, August 3, 2026, and August 3, 2027. The debentures are guaranteed by Arco Brazil.

On December 1, 2021, we issued US$150 million in senior notes convertible into our Class A common shares in the amount of: (i) US$100 million to Arcade GF II Holdings, LLC and Arcade OF V Holdings, LLC, entities affiliated with Dragoneer; and (ii) US$50 million to General Atlantic Partners (Bermuda) H, L.P., an entity affiliated with General Atlantic. The convertibles notes bear interest at 8% per annum in fixed Brazilian reais and mature on November 15, 2028. Each note is convertible at the option of the holder into our 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 a premium of approximately 65% to the trailing 30-day volume-weighted share price at the time of signing the investment agreements for the convertible notes.

On November 11, 2021, Arco Brazil, as guarantor, entered into an international loan agreement with Itaú Unibanco Nassau Branch, as lender, and Geekie, as borrower, in the amount of US$11.0 million. The loan accrues interest at a rate equal to 2.452% per annum and is repayable in equal quarterly installments from February 10, 2022, to October 28, 2024. We contracted swap derivatives financial instruments to protect our exposure to the foreign currency risk, which changes the effective interest rate for this loan to 100% of the CDI rate plus 1.7% per annum.

On August 25, 2021, we issued through our wholly owned subsidiary, CBE, R$900 million in debentures, bearing interest at the CDI rate plus 1.7% per annum and maturing on August 25, 2023. These debentures were prepaid on August 5, 2022.

On January 1, 2021, CBE acting as guarantor, entered into a lease agreement with HP Financial Services Arrendamento Mercantil S.A. and Geekie. In addition, on April 1, 2021, Arco Brazil, as guarantor, entered into a lease agreement with HP Financial Services Arrendamento Mercantil S.A. and Geekie.

On July 1, 2020, we entered into a loan agreement with Banco Santander (Brasil) S.A. in the amount of R$100.0 million. The loan accrues interest at a rate equal to 100% of the CDI rate plus 2.7% per annum. The loan was repaid in December 2021.

On July 1, 2020, we entered into two loan agreements with Itaú Unibanco S.A. in the amount of R$100.0 million each, both loans maturing in January 2022 (single installment). The loans accrue interest at a rate equal to 100% of the CDI rate plus 2.7% per annum, payable in 17 installments, and were repaid in full on January 3, 2022.

As collateral for the payment of the remaining purchase price of Positivo Acquisition, on October 25, 2018, we have entered a bank guarantee with Banco Bradesco S.A. In accordance with the terms of such bank guarantee, 100% of the shares held by Arco Brazil in SAE and 20% of the shares held by Arco Brazil in CBE were assigned in guarantee (*alienação fiduciária*) to Banco Bradesco S.A.

On November 13, 2018, we entered into a fiduciary agreement with Banco Safra S.A., as amended on December 3, 2020, to guarantee the payment due under the lease agreements of our São Paulo offices located at Rua Augusta 2840.

***Off-balance sheet arrangements***

As of December 31, 2022, we did not have any off-balance sheet arrangements.

#### Capital Expenditures
In the years ended December 31, 2022, 2021 and 2020, we made capital expenditures of R$180.2 million, R$211.4 million and R$107.6 million, respectively. These capital expenditures mainly include expenditures related to the acquisition of property and equipment and the acquisition of intangible assets. Our capital expenditures decreased in 2022 as compared to 2021 mainly due to decreased investments in educational technology in the leasing model in 2022.

We expect to increase our capital expenditures to support the growth in our business and operations. We expect to meet our capital expenditure needs for the foreseeable future from our operating cash flow and our existing cash and cash equivalents. Our future capital requirements will depend on several factors, including our growth rate, the expansion of our research and development efforts, employee headcount, marketing and sales activities, the introduction of new features to our existing products and the continued market acceptance of our products. We are monitoring our cash position and if needed acquisition of funds from financial institutions, private debit or public offerings will be timely analyzed.

B. Compensation

Under Cayman Islands law, we are not required to disclose compensation paid to our senior management on an individual basis and we have not otherwise publicly disclosed this information elsewhere.

*Our executive officers, directors and management receive fixed and variable compensation, through our short-term (annual bonus) and Long-Term Incentive Plans (LTIP). They also receive benefits in line with market practice in Brazil.*

***Fixed Compensation***

*The fixed component of our key executive officer compensation is set on market terms and adjusted annually. In general, approximately 32% of our key executive officer compensation is composed of a fixed component as of March 30, 2023.*

***Variable Compensation***

*The variable component of our key executive officer compensation consists of annual cash bonuses and awards of shares (or the cash equivalent) through the LTIP. Cash bonuses are paid to key executive officers based on previously agreed targets for the business. The variable compensation represents approximately 68% of our key executive officer's compensation as of March 30, 2023, 50% of which is linked to corporate key performance indicator (KPI) target achievements for all senior management and the remaining 50% is linked to individual targets related to each corporate function.*

***Share-based Compensation***

*Shares (or the cash equivalent) are awarded under our share options long-term incentive program, as discussed below.*

*We believe that our LTIP enhances the dedication of our executives towards achieving our goals.*

***Long-Term Incentive Plan and Share-based Compensation***

 *Restricted Shares Grant Plan*

On April 30, 2019, our board of directors approved our restricted share long-term incentive program, or the "Restricted Shares Grant Plan." The maximum number of shares that can be issued under the Restricted Shares Grant Plan may not exceed 5% of our share capital at any time. The Restricted Shares Grant Plan is administered by our board of directors and a designated committee (the "Restricted Share Plan Advisory Committee").

Our and our controlled companies' directors, officers, employees and professionals of any nature may participate in the Restricted Shares Grant Plan, which is composed of two underlying programs: (i) the regular program, pursuant to which we will grant restricted shares to the participant at no cost, subject to certain vesting and/or performance conditions (the "Regular Program") and (ii) the matching shares program, pursuant to which we 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 our board of directors to be used as an investment in investment shares, provided certain vesting conditions are satisfied (the "Matching Program").

Under the matching shares program, participants are required to (i) be employed or providing services to us 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 negotiate such shares. Under the regular shares program, the participant's right to receive the restricted shares will be subject to the participant remaining continuously bound as our employee, officer, or director, as applicable, through each vesting, which may not exceed five years.

[**Table of Contents**](#TOC)

If a participant is dismissed by us with cause or voluntarily terminates his or her employment or service relationship with us, the participant will forfeit any right to the unvested shares. If the participant is dismissed by us without cause, 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. In case of the participant's death or permanent disability, the participant (or his or her heirs) will be entitled to receive all the granted shares, whether or not vested, which will be delivered upon termination of the original vesting period.

If our shares cease to be publicly traded, there shall be an acceleration of the vesting period and the shares shall be delivered to the applicable participant as set forth in their award agreement. In each such case, each participant may elect to (i) sell his or her granted shares at a price equal to the price at which the shares were sold in connection with the transaction resulting in the Company becoming privately owned, or (ii) remain a shareholder of the Company subject to the approval of the board of directors.

Awards of restricted shares and matching shares may be settled in shares or cash, as determined by our board of directors. The restricted shares and matching shares may not be pledged, assigned or transferred to third parties, without the prior approval of our board of directors. Participants in the Restricted Share Grant Plan will be subject to a two-year post-termination of employment or service noncompete and prohibition against soliciting our employees, service providers and customers. The Restricted Shares Grant Plan provides that the Company shall withhold a portion of the restricted shares units to comply with all taxes applicable to the delivery of the restricted shares units to the beneficiary.

As of March 30, 2023, we had 1,879,644 restricted shares units outstanding under the Regular Program and Matching Program.

*Regular Programs*

The Restricted Plan Advisory Committee approves the participants of each Regular Program, from time to time. In 2020, we concluded the 1st, 3rd and 6th Regular Programs and delivered 482,733 shares. In 2021, we concluded the 2nd, 7th and 8th Regular Programs and delivered 37,823 shares.

C. Board Practices

#### Committees of the Board of Directors
Our board of directors has two standing committees: Audit Committee and Compensation Committee.

#### Audit Committee
The audit committee, which consists of Edward Ruiz, Beatriz Amary and Carla Schmitzberger, assists our board of directors in overseeing our accounting and financial reporting processes and the audits of our financial statements. In addition, the audit committee is directly responsible for the appointment, compensation, retention and oversight of the work of our independent registered public accounting firm. Edward Ruiz serves as Chairman of the audit committee. The audit committee consists exclusively of members of our board of directors who are financially literate, and Edward Ruiz is considered an "audit committee financial expert" as defined by the SEC. Our board of directors has determined that Edward Ruiz, Beatriz Amary and Carla Schmitzberger dos Santos satisfy the "independence" requirements set forth in Rule 10A-3 under the Exchange Act.

The audit committee is governed by a charter that complies with Nasdaq rules. The audit committee is responsible for, among other matters:

● the appointment, compensation, retention and oversight of any auditor or accounting firm engaged for the purpose of preparing or issuing an audit report or performing other audit, review or attest services;

● pre-approving the audit services and non-audit services to be provided by our independent auditor before the auditor is engaged to render such services;

[**Table of Contents**](#TOC)

● reviewing and discussing with the independent auditor its responsibilities under generally accepted auditing standards, the planned scope and timing of the independent auditor's annual audit plan(s) and significant findings from the audit;

● obtaining and reviewing a report from the independent auditor describing all relationships between the independent auditor and the Company consistent with the applicable PCAOB requirements regarding the independent auditor's communications with the audit committee concerning independence;

● confirming and evaluating the rotation of the audit partners on the audit engagement team as required by law;

● reviewing with management and the independent auditor, in separate meetings whenever the Audit Committee deems appropriate, any analyses or other written communications prepared by the Management and/or the independent auditor setting forth significant financial reporting issues and judgments made in connection with the preparation of the financial statements, including analyses of the effects of alternative IFRS methods on the financial statements; and other critical accounting policies and practices of the Company;

● reviewing, in conjunction with the Chief Executive Officer and Chief Financial Officer of the Company, the Company's disclosure controls and procedures and internal control over financial reporting;

● approving or ratifying any related person transaction in accordance with our internal policies and applicable legislation; and

● review, direct and supervise the actions of the Ethics Committee, which analyzes, investigates and take the proper measures in case of misconduct by any employee and breaches of the Company's Code of Ethics and other internal policies.

The audit committee meets as often as it determines is appropriate to carry out its responsibilities, but in any event, meets at least four times per year.

#### Compensation Committee
Our compensation committee was created on March 12, 2020, by our board of directors, and it is composed of two members, Edward Ruiz and Carla Schmitzberger.

Our compensation committee assists our board of directors in reviewing and approving the compensation structure, including all forms of compensation, relating to our directors and executive officers. The committee reviews the total compensation package for our executive officers and directors and recommends to the board of directors for determination the compensation of each of our directors and executive officers and will periodically review and approve any long-term incentive compensation or equity plans, programs or similar arrangements, annual bonuses, and employee pension and benefits plans. Our board of directors has determined that Edward Ruiz and Carla Schmitzberger satisfy the requirements set forth Nasdaq Listing Rule 5605(d), which requires that a compensation committee consist entirely of independent directors.

#### Restricted Shares Plan Advisory Committee

#### Investment in isaac
On January 25, 2021, we entered into a Series B Ordinary Shares Purchase Agreement with INCO Limited, the controlling entity of OISA Tecnología e Serviços Ltda. ("isaac"). isaac, which was indirectly controlled by David Peixoto dos Santos, Arco's former chief financial officer, is a vertical platform to address schools' overarching needs with software and financial solutions, including working capital management issues. Pursuant to the purchase agreement, we acquired 8,571,427 series B ordinary shares of isaac, or approximately 30% of its outstanding share capital, for a purchase price equal to R$25.0 million.

On April 22, 2021, we and other investors entered into a Series A and Series A-1 Preferred Shares Purchase Agreement, pursuant to which we acquired 3,653,788 series A preferred shares of isaac for a purchase price equal to R$33.2 million, with the option to acquire an additional 2,935,010 Series A-1 preferred shares, which we exercised on September 17, 2021 for a purchase price equal to R$52.0 million.

In January 2023, we subsequently acquired an additional 75.1% interest in isaac, whereupon it became a wholly owned subsidiary of ours. See "Item 4. Information on the Company—A. History and development of the company—Acquisitions and Investments—Acquisition of Isaac."

#### Sale of Escola de Aplicação São José dos Campos Ltda.
On January 2, 2019, we sold the shares we owned in Escola de Aplicação São José dos Campos Ltda. to its minority shareholders. The transaction price of R$3.7 million will be paid in sixteen quarterly installments from January 2022 to October 2025, adjusted by the IGP-M. On October 23, 2020, the buyers anticipated the payment of the installments due in 2022 and the first installment of 2023. On February 26, 2021, the parties executed an amendment to the purchase agreement, which was agreed that the installments to be paid in 2021 will be adjusted by the IPCA. The purchase price was fully paid on August 23, 2021.

#### Indemnification Agreements
We have entered into indemnification agreements with each of our directors and executive officers. Pursuant to these agreements, we have agreed to indemnify and hold harmless each director and officer to the full extent permitted by applicable law in the event of any claim made against him or her in any proceeding due to the fact that he or she is or was a director or officer of our company or served at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise.

In addition, under the terms of these agreements we have agreed to cover all expenses actually and reasonably incurred by each director and officer in connection with any such proceeding, with certain limited exceptions.

The indemnification extends to the beneficiary's services as a director or officer prior to the date of the indemnification agreement as well as afterward. It continues after the beneficiary ceases to be a director or officer.

C. Interests of experts and counsel

Not applicable.

#### ITEM 8. FINANCIAL INFORMATION
A. Consolidated statements and other financial information

#### Financial statements
See "Item 18. Financial Statements," which contains our audited financial statements prepared in accordance with IFRS.

#### Dividends and dividend policy
We have not adopted a dividend policy with respect to future distributions of dividends. The amount of any distributions will depend on many factors such as our results of operations, financial condition, cash requirements, prospects and other factors deemed relevant by our board of directors and, where applicable, our shareholders. We currently intend to retain all available funds and any future earnings, if any, to fund the development and expansion of our business and we do not anticipate paying any cash dividends in the foreseeable future.

Subject to the Companies Act, Arco's shareholders may, by resolution passed by a simple majority of the voting rights entitled to vote at a general meeting, declare dividends (including interim dividends) to be paid to shareholders but no dividend shall be declared in excess of the amount recommended by the board of directors. The board of directors may also declare dividends. Dividends may be declared and paid out of funds lawfully available to Arco. Except as otherwise provided by the rights attached to shares and the Articles of Association of Arco, all dividends shall be paid in proportion to the number of Class A common shares or Class B common shares a shareholder holds at the date the dividend is declared (or such other date as may be set as a record date); but, (i) if any share is issued on terms providing that it shall rank for dividend as from a particular date, share shall rank for dividend accordingly, and (ii) where we have shares in issue which are not fully paid up (as to par value) we may pay dividends in proportion to the amounts paid up on each share.

The holders of Class A common shares and Class B common shares shall be entitled to share equally in any dividends that may be declared in respect of Arco's common shares from time to time. In the event that a dividend is paid in the form of Class A common shares or Class B common shares, or rights to acquire Class A common shares or Class B common shares, (1) the holders of Class A common shares shall receive Class A common shares, or rights to acquire Class A common shares, as the case may be; and (2) the holders of Class B common shares shall receive Class B common shares, or rights to acquire Class B common shares, as the case may be.

We have not declared or paid any dividends to our shareholders since our incorporation in the Cayman Islands on April 12, 2018.

[**Table of Contents**](#TOC)

#### Certain Cayman Islands and Brazilian Legal Requirements Related to Dividends
Under the Companies Act and our Articles of Association, a Cayman Islands company may pay a dividend out of either its profit or share premium account, but a dividend may not be paid if this would result in the company being unable to pay its debts as they fall due in the ordinary course of business. According to our Articles of Association, dividends can be declared and paid out of funds lawfully available to us, which include the share premium account. Dividends, if any, would be paid in proportion to the number of common shares a shareholder holds. For further information, see "Item 10. Additional Information—E. Taxation—Cayman Islands Tax Considerations."

Additionally, please refer to "Item 3. Key Information—D. Risk Factors—Certain Factors Relating to Our Business and Industry—We depend on dividend distributions by our subsidiaries, and we may be adversely affected if the performance of our subsidiaries is not positive or if Brazil imposes legal restrictions on dividend distributions by subsidiaries." Our ability to pay dividends is directly related to positive and distributable net results from our Brazilian subsidiaries. If, for any legal reasons due to new laws or bilateral agreements between countries, they are unable to pay dividends to Cayman Islands companies, or if a Cayman Islands company becomes incapable of receiving them, we may not be able to make any dividend payments in the future.

#### Legal proceedings
We are, and may be from time to time, involved in disputes that arise in the ordinary course of our business. Claims against us can be time-consuming, result in costly litigation, require significant management time and result in the diversion of significant operational resources.

We are subject to a number of judicial and administrative proceedings in the Brazilian court systems, including civil, labor and tax law claims and other proceedings. We recognize provisions for legal proceedings in our financial statements when (i) it is probable that an outflow of resources will be required to settle the obligation, and (ii) a reliable estimate can be made of the amount of the obligation. The assessment by our management of the likelihood of loss includes analysis by outside counsel of available evidence, the hierarchy of laws, available case law, recent court rulings and their relevance in the Brazilian legal system. Our provisions for probable losses arising from these matters are estimated and periodically adjusted by management. In making these adjustments, our management relies on the opinions of our external legal advisors.

As of December 31, 2022, we had a provision for legal proceedings of R$2.3 million recorded in our financial statements in connection with legal proceedings, based on the advice of our external legal counsel that the likelihood of loss in connection with such proceedings is probable. However, legal proceedings are inherently unpredictable and subject to significant uncertainties. If one or more cases were to result in a judgment against us in any reporting period for amounts that exceeded our management's expectations, the impact on our operating results or financial condition for that reporting period could be material. See "Item 3. Key Information—D. Risk Factors—Certain Factors Relating to Our Business and Industry—Unfavorable decisions in our legal, arbitration or administrative proceedings may adversely affect us."

#### Civil Matters
As of December 31, 2022, we were a defendant to approximately 103 judicial and administrative proceedings of a civil nature for which we did not record any provision based on the advice of our external legal counsel that the likelihood of loss in connection with these proceedings was not probable. The civil claims to which we are a party generally relate to consumer claims, including those related to the early termination of certain of our agreements, among others. We believe these proceedings are unlikely to have a material adverse impact, individually, or in the aggregate, on our results of operations or financial condition.

As of December 31, 2022, we were party to two administrative proceedings of a civil nature filed by the prosecutor's offices in the States of Ceará and Maranhão.

[**Table of Contents**](#TOC)

The proceeding in the State of Ceará results from a complaint filed on behalf of some students' parents of one of our partner schools alleging that the students are required to purchase our educational material only from the partner school in which the student is enrolled in at prices higher than those charged by other partner schools in the region, with no option to purchase such educational material at bookstores or other points of sale. In September 2022, a decision was rendered against SAS requiring SAS to pay a fine totaling R$123 thousand. We appealed this decision in December 2022. As of the date of this annual report, our appeal is under review by the 5<sup>th</sup> public treasury court of Fortaleza. The decision requiring SAS to pay the fine is suspended pending the outcome of the appeal, and we have made a judicial deposit of the amount of the fine to the court.

The proceedings filed by the prosecutor's offices in the state of Maranhão, result from the questioning of students' parents of some our partner schools in the region about the impossibility of using used books and acquiring access to our digital content without acquiring the full platform provided by us. We have already filed our responses, which are currently under review.

As of the date of this annual report, both proceedings are still ongoing and at an early stage, and we cannot estimate the amount of any additional eventual fines or any claim for damages, or collective non-material damages that may be imposed on us or confirm the claims that may be asserted against us. However, the applicable prosecutors' offices may file a public civil claim or require the parties to enter into a settlement agreement (*Termo de Ajustamento de Conduta - TAC*), requiring the partner schools to adjust its commercial practices as they relate to the sale of educational material.

***Labor Matters***

As of December 31, 2022, we were party to approximately 12 labor-related judicial and administrative proceedings for which we did not record any provision based on the advice of our external legal counsel that the likelihood of loss in connection with these proceedings was not probable. In general, the labor claims to which we are a party were filed by former employees or third-party employees seeking our joint and/or subsidiary liability for the acts of our suppliers and service providers. The principal claims involved in these labor suits relate to overtime, salary equalization termination fees, and indemnities based on Brazilian labor laws. We believe these proceedings are unlikely to have a material adverse impact, individually or in the aggregate, on our results of operations or financial condition.

***Tax and Social Security Matters***

As of December 31, 2022, we were party to 5 administrative tax and social security proceedings for which we did not record any provision based on the advice of our external legal counsel that the likelihood of loss in connection with this proceeding was not probable.

***Request for Arbitration***

On September 19, 2019, Mr. Ulisses Borges Cardinot, a 48.52% 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, CBE and Arco Brazil.

This request for arbitration purporting to assert Mr. Cardinot's rights under the Investment Agreement (for more information regarding the Investment Agreement, see "Item 4. Information on the Company A. History and development of the company—Acquisitions and Investments—Acquisition of International School") is still ongoing.

Mr. Cardinot has asserted that, among others, he is entitled to receive shares of Arco Platform and the purchase price due pursuant to the Investment Agreement is materially higher. On October 10, 2019, we filed our response to the request for arbitration, denying Mr. Cardinot's claims and affirming that Arco Platform and Arco Educação cannot be parties to the arbitration since they are not parties to the Investment Agreement. On July 6, 2020, Arco Brazil, the Company and CBE filed their statements of defense. On August 10, 2020, Ulisses Cardinot filed his reply to the statements of defense. On September 14, 2020, Arco Brazil, the Company and CBE filed their rejoinders.

[**Table of Contents**](#TOC)

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 CBE and its calculation will be further discussed in the award phase of the arbitration proceeding. However, the arbitration panel decided that (i) Arco Platform and Arco Brazil are not subject to the terms of the Investment Agreement and, therefore, will not be part of the arbitration proceeding; (ii) Mr. Cardinot is not entitled to receive shares of Arco Platform; and (iii) the amount due by CBE will be calculated based on 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.

The submissions had not caused a material impact on our assessment of the applicable liabilities or on the provisions made by us in the financial statements.

We are vigorously defending ourselves on the award phase of the arbitration proceeding. If an unfavorable decision were to occur, it could result in a material adverse impact on our financial position and results of operations in the period in which the decision occurs, or in future periods, and on the price of our Class A common shares.

A.&nbsp;&nbsp;&nbsp;&nbsp;Share capital

Not applicable.

[**Table of Contents**](#TOC)

B.&nbsp;&nbsp;&nbsp;&nbsp; Memorandum and articles of association

Our shareholders adopted the Amended and Restated Memorandum and Articles of Association included as Exhibit 3.1 to the Amendment No. 2 to our registration statement on Form F-1 (File no. 333-227007), filed with the SEC on September 12, 2018.

#### Share Capital
The Memorandum and Articles of Association authorize two classes of common shares: Class A common shares, which are entitled to one vote per share, and Class B common shares, which are entitled to 10 votes per share and to maintain a proportional ownership interest in the event that additional Class A common shares are issued. Any holder of Class B common shares may convert his or her shares at any time into Class A common shares on a share-for-share basis. The rights of the two classes of common shares are otherwise identical, except as described below. The implementation of this dual class structure was required by Oto Brasil de Sá Cavalcante and Ari de Sá Cavalcante Neto, our principal shareholders, as a condition of undertaking the initial public offering of our common shares. See "—Anti-Takeover Provisions in our Articles of Association—Two Classes of Shares."

As of December 31, 2022, Arco we a total issued share capital of U.S.$2,847.75, divided into 56,954,952 common shares of a nominal or par value of U.S.$0.00005. Those common shares are divided into 29,554,104 Class A common shares and 27,400,848 Class B common shares.

**Treasury Shares**

As of December 31, 2022, we had 1,047,142 shares in treasury.

**Issuance of Shares**

Except as expressly provided in Arco's Articles of Association, Arco's board of directors has general and unconditional authority to allot, grant options over, offer or otherwise deal with or dispose of any unissued shares in the company's capital without the approval of our shareholders (whether forming part of the original or any increased share capital), either at a premium or at par, with or without preferred, deferred or other special rights or restrictions, whether in regard to dividend, voting, return of capital or otherwise and to such persons, on such terms and conditions, and at such times as the directors may decide, but so that no share shall be issued at a discount, except in accordance with the provisions of the Companies Act. In accordance with its Articles of Association, Arco shall not issue bearer shares.

Arco's Articles of Association provide that at any time that there are Class A common shares in issue, additional Class B common shares may only be issued pursuant to (1) a share split, subdivision of shares or similar transaction or where a dividend or other distribution is paid by the issue of shares or rights to acquire shares or following capitalization of profits, (2) a merger, consolidation, or other business combination involving the issuance of Class B common shares as full or partial consideration, or (3) an issuance of Class A common shares, whereby holders of the Class B common shares are entitled to purchase a number of Class B common shares that would allow them to maintain their proportional ownership interests in Arco (following an offer by Arco to each holder of Class B common shares to issue to such holder, upon the same economic terms and at the same price, such number of Class B common shares as would ensure such holder may maintain a proportional ownership interest in Arco pursuant to Arco's Articles of Association). In light of: (a) the above provisions; (b) the fact that future transfers by holders of Class B common shares will generally result in those shares converting to Class A common shares, subject to limited exceptions as provided in the Memorandum and Articles of Association; and (c) the ten-to-one voting ratio between our Class B common shares and Class A common shares, means that holders of our Class B common shares will in many situations continue to maintain control of all matters requiring shareholder approval. This concentration of ownership and voting power will limit or preclude your ability to influence corporate matters for the foreseeable future. For more information see "—Preemptive or Similar Rights."

Arco's Articles of Association also provide that the issuance of non-voting common shares requires the affirmative vote of a majority of the of then-outstanding Class A common shares.

[**Table of Contents**](#TOC)

**Fiscal Year**

Arco's fiscal year begins on January 1 of each year and ends on December 31 of the same year.

**Voting Rights**

The holders of the Class A common shares and Class B common shares have identical rights, except that (i) the holder of Class B common shares is entitled to 10 votes per share, whereas holders of Class A common shares are entitled to one vote per share, (ii) Class B common shares have certain conversion rights and (iii) the holder of Class B common shares is entitled to maintain a proportional ownership interest in the event that additional Class A common shares are issued. For more information see "—Preemptive or Similar Rights" and "—Conversion." The holders of Class A common shares and Class B common shares vote together as a single class on all matters (including the election of directors) submitted to a vote of shareholders, except as provided below and as otherwise required by law.

Arco's Articles of Association provide as follows regarding the respective rights of holders of Class A common shares and Class B common shares:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) class consents from the holders of Class A common shares or Class B common shares, as applicable, shall be required for any variation to the rights attached to their respective class of shares, however, the Directors may treat any two or more classes of shares as forming one class if they consider that all such classes would be affected in the same way by the proposal;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the rights conferred on holders of Class A common shares shall not be deemed to be varied by the creation or issue of further Class B common shares and vice versa; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the rights attaching to the Class A common shares and the Class B common shares shall not be deemed to be varied by the creation or issue of shares with preferred or other rights, including, without limitation, shares with enhanced or weighted voting rights.

As set forth in the Articles of Association, the holders of Class A common shares and Class B common shares, respectively, do not have the right to vote separately if the number of authorized shares of such class is increased or decreased. Rather, the number of authorized Class A common shares and Class B common shares may be increased or decreased (but not below the number of shares of such class then outstanding) by the affirmative vote of the holders of a majority of the voting power of the issued and outstanding Class A common shares and Class B common shares, voting together in a general meeting.

#### Preemptive or Similar Rights
The Class A common shares and Class B common shares are not entitled to preemptive rights upon transfer and are not subject to conversion (except as described below under "—Conversion"), redemption or sinking fund provisions.

The Class B common shares are entitled to maintain a proportional ownership interest in the event that additional Class A common shares are issued. As such, except for certain exceptions, if Arco issues Class A common shares, it must first make an offer to each holder of Class B common shares to issue to such holder, upon the same economic terms and at the same price, such number of Class B common shares as would ensure such holder may maintain a proportional ownership interest in Arco. This right to maintain a proportional ownership interest may be waived by the holders of a majority of the Class B common shares.

[**Table of Contents**](#TOC)

#### Conversion
The outstanding Class B common shares are convertible at any time as follows: (1) at the option of the holder, a Class B common share may be converted at any time into one Class A common share or (2) upon the election of the holders of a majority of the then outstanding Class B common shares, all outstanding Class B common shares may be converted into a like number of Class A common shares. In addition, each Class B common share will convert automatically into one Class A common share upon any transfer, whether or not for value, except for certain transfers described in the Articles of Association, including transfers to affiliates, transfers to and between the Founding Shareholders, their family members and their respective heirs and successors, trusts solely for the benefit of the shareholder or their affiliates, and partnerships, corporations and other entities exclusively owned by the shareholder or their affiliates and certain transfers to organizations that are exempt from taxation under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended. Furthermore, each Class B common share will convert automatically into one Class A common share and no Class B common shares will be issued thereafter if, at any time, the total number of the issued and outstanding Class B common shares is less than 10% of the total number of shares outstanding.

No class of Arco's common shares may be subdivided or combined unless the other class of common shares is concurrently subdivided or combined in the same proportion and in the same manner.

#### Equal Status
Except as expressly provided in Arco's Articles of Association, Class A common shares and Class B common shares have the same rights and privileges and rank equally, share ratably and are identical in all respects as to all matters. In the event of any merger, consolidation, scheme, arrangement or other business combination requiring the approval of our shareholders entitled to vote thereon (whether or not Arco is the surviving entity), the holders of Class A common shares shall have the right to receive, or the right to elect to receive, the same form of consideration as the holders of Class B common shares, and the holders of Class A common shares shall have the right to receive, or the right to elect to receive, at least the same amount of consideration on a per share basis as the holders of Class B common shares. In the event of any (1) tender or exchange offer to acquire any Class A common shares or Class B common shares by any third-party pursuant to an agreement to which Arco is a party, or (2) any tender or exchange offer by Arco to acquire any Class A common shares or Class B common shares, the holders of Class A common shares shall have the right to receive, or the right to elect to receive, the same form of consideration as the holders of Class B common shares, and the holders of Class A common shares shall have the right to receive, or the right to elect to receive, at least the same amount of consideration on a per share basis as the holders of Class B common shares.

#### Record Dates
For the purpose of determining shareholders entitled to notice of, or to vote at any general meeting of shareholders or any adjournment thereof, or shareholders entitled to receive dividend or other distribution payments, or in order to make a determination of shareholders for any other purpose, Arco's board of directors may set a record date which shall not exceed forty (40) clear days prior to the date where the determination will be made.

#### General Meetings of Shareholders
As a condition of admission to a shareholders' meeting, a shareholder must be duly registered as a shareholder of Arco at the applicable record date for that meeting and, in order to vote, all calls or installments then payable by such shareholder to Arco in respect of the shares that such shareholder holds must have been paid.

Subject to any special rights or restrictions as to voting then attached to any shares, at any general meeting every shareholder who is present in person or by proxy (or, in the case of a shareholder being a corporation, by its duly authorized representative not being himself or herself a shareholder entitled to vote) shall have one vote per Class A common share and 10 votes per Class B common share.

As a Cayman Islands exempted company, Arco is not obliged by the Companies Act to call annual general meetings; however, the Articles of Association provide that in each year the company will hold an annual general meeting of shareholders, at a time

[**Table of Contents**](#TOC)

determined by the board of directors. For the annual general meeting of shareholders, the agenda will include, among other things, the presentation of the annual accounts and the report of the directors. In addition, the agenda for an annual general meeting of shareholders will only include such items as have been included therein by the board of directors.

Also, Arco may, but is not required to (unless required by the laws of the Cayman Islands), hold extraordinary general meetings during the year. General meetings of shareholders are generally expected to take place in São Paulo, Brazil, but may be held elsewhere if the directors so decide.

The Companies Act provides shareholders a limited right to request a general meeting and does not provide shareholders with any right to put any proposal before a general meeting in default of a company's Articles of Association. However, these rights may be provided in a company's Articles of Association. Arco's Articles of Association provide that upon the requisition of one or more shareholders representing not less than one-third of the voting rights entitled to vote at general meetings, the board will convene an extraordinary general meeting and put the resolutions so requisitioned to a vote at such meeting. The Articles of Association provide no other right to put any proposals before annual general meetings or extraordinary general meetings.

Subject to regulatory requirements, the annual general meeting and any extraordinary general meetings must be called by not less than ten (10) clear days' notice prior to the relevant shareholders meeting and convened by a notice discussed below. Alternatively, upon the prior consent of all holders entitled to receive notice, with regards to the annual general meeting, and the holders of 95% in par value of the shares entitled to attend and vote at an extraordinary general meeting, that meeting may be convened by a shorter notice and in a manner deemed appropriate by those holders.

Arco will give notice of each general meeting of shareholders by publication on its website and in any other manner that it may be required to follow in order to comply with Cayman Islands law, Nasdaq and SEC requirements. The holders of registered shares may be given notice of a shareholders' meeting by means of letters sent to the addresses of those shareholders as registered in our shareholders' register, or, subject to certain statutory requirements, by electronic means.

**Holders whose shares are registered in the name of DTC or its nominee, which we expect will be the case for all holders of Class A common shares, will not be a shareholder or member of the company and must rely on the procedures of DTC regarding notice of shareholders' meetings and the exercise of rights of a holder of the Class A common shares.**

A quorum for a general meeting consists of any one or more persons holding or representing by proxy not less than one-third of the aggregate voting power of all shares in issue and entitled to vote upon the business to be transacted.

A resolution put to a vote at a general meeting shall be decided on a poll. An ordinary resolution to be passed by the shareholders at a general meeting requires the affirmative vote of a simple majority of the votes cast by, or on behalf of, the shareholders entitled to vote, present in person or by proxy and voting at the meeting. A special resolution requires the affirmative vote on a poll of no less than two-thirds of the votes cast by the shareholders entitled to vote who are present in person or by proxy at a general meeting. Both ordinary resolutions and special resolutions may also be passed by a unanimous written resolution signed by all the shareholders of our Company, as permitted by the Companies Act and our Articles of Association.

[**Table of Contents**](#TOC)

Pursuant to Arco's Articles of Association, general meetings of shareholders are to be chaired by the chairman of our board of directors or in his absence the vice-chairman of the board of directors. If the chairman or vice-chairman of our board of directors is absent, the directors present at the meeting shall appoint one of them to be chairman of the general meeting. If neither the chairman nor another director is present at the general meeting within 15 minutes after the time appointed for holding the meeting, the shareholders present in person or by proxy and entitled to vote may elect any one of the shareholders to be chairman. The order of business at each meeting shall be determined by the chairman of the meeting, and he or she shall have the right and authority to prescribe such rules, regulations and procedures and to do all such acts and things as are necessary or desirable for the proper conduct of the meeting, including, without limitation, the establishment of procedures for the maintenance of order and safety, limitations on the time allotted to questions or comments on the affairs of the Company, restrictions on entry to such meeting after the time prescribed for the commencement thereof, and the opening and closing of the polls.

#### Liquidation Rights
If Arco is voluntarily wound up, the liquidator, after taking into account and giving effect to the rights of preferred and secured creditors and to any agreement between Arco and any creditors that the claims of such creditors shall be subordinated or otherwise deferred to the claims of any other creditors and to any contractual rights of set-off or netting of claims between Arco and any person or persons (including without limitation any bilateral or any multi-lateral set-off or netting arrangements between the company and any person or persons) and subject to any agreement between Arco and any person or persons to waive or limit the same, shall apply Arco's property in satisfaction of its liabilities *pari passu* and subject thereto shall, subject to the rights attaching to any share, distribute the property *pari passu* amongst the shareholders in proportion to the capital paid up at the commencement of the winding up on the shares held by them respectively.

#### Changes to Capital
Pursuant to the Articles of Association, Arco may from time to time by ordinary resolution:

● increase its share capital by such sum, to be divided into shares of such amount, as the resolution shall prescribe;

● consolidate and divide all or any of its share capital into shares of a larger amount than its existing shares;

● convert all or any of its paid-up shares into stock and reconvert that stock into paid-up shares of any denomination;

● subdivide its existing shares or any of them into shares of a smaller amount, provided that in the subdivision the proportion between the amount paid and the amount, if any, unpaid on each reduced share shall be the same as it was in the case of the share from which the reduced share is derived; or

● cancel any shares which, at the date of the passing of the resolution, have not been taken or agreed to be taken by any person and diminish the amount of its share capital by the amount of the shares so canceled.

Arco's shareholders may by special resolution, subject to confirmation by the Grand Court of the Cayman Islands on an application by the Company for an order confirming such reduction, reduce its share capital or any capital redemption reserve in any manner permitted by law.

In addition, subject to the provisions of the Companies Act and our Articles of Association, Arco may:

● issue shares on terms that they are to be redeemed or are liable to be redeemed;

● purchase its own shares (including any redeemable shares); and

● make a payment in respect of the redemption or purchase of its own shares in any manner authorized by the Companies Act, including out of its own capital.

#### Transfer of Shares
Subject to any applicable restrictions set forth in the Articles of Association, any shareholder of Arco may transfer all or any of his or her common shares by an instrument of transfer in the usual or common form or in the form prescribed by the Nasdaq or any other form approved by the Company's board of directors.

The Class A common shares are traded on the Nasdaq in book-entry form and may be transferred in accordance with Arco's Articles of Association and Nasdaq's rules and regulations.

However, Arco's board of directors may, in its absolute discretion, decline to register any transfer of any common share which is either not fully paid up to a person of whom it does not approve or is issued under any share incentive scheme for employees which contains a transfer restriction that is still applicable to such common share. The board of directors may also decline to register any transfer of any common share unless:

● a fee of such maximum sum as the Nasdaq may determine to be payable or such lesser sum as the board of directors may from time to time require is paid to Arco in respect thereof;

● the instrument of transfer is lodged with Arco, accompanied by the certificate (if any) for the common shares to which it relates and such other evidence as our board of directors may reasonably require to show the right of the transferor to make the transfer;

● the instrument of transfer is in respect of only one class of shares;

● the instrument of transfer is properly stamped, if required;

● the common shares transferred are free of any lien in favor of Arco; and

● in the case of a transfer to joint holders, the transfer is not to more than four joint holders.

If the directors refuse to register a transfer they are required, within two months after the date on which the instrument of transfer was lodged, to send to the transferee notice of such refusal.

#### Share Repurchase
The Companies Act and the Articles of Association permit Arco to purchase its own shares, subject to certain restrictions. The board of directors may only exercise this power on behalf of Arco, subject to the Companies Act, the Articles of Association and to any applicable requirements imposed from time to time by the SEC, the Nasdaq, or by any recognized stock exchange on which our securities are listed.

#### Dividend Rights
See "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Dividends and Dividend Policy" for further information regarding dividend rights.

#### Appointment, Disqualification and Removal of Directors
Arco is managed by its board of directors. The Articles of Association provide that, unless otherwise determined by a special resolution of shareholders, the board of directors will be composed of four to 11 directors, with the number being determined by a majority of the directors then in office. There are no provisions relating to retirement of directors upon reaching any age limit. The Articles of Association also provide that, while Arco's shares are admitted to trading on Nasdaq, the board of directors must always comply with the residency and citizenship requirements of the U.S. securities laws applicable to foreign private issuers.

[**Table of Contents**](#TOC)

The Articles of Association provide that directors shall be elected by an ordinary resolution of our shareholders, which requires the affirmative vote of a simple majority of the votes cast on the resolution by the shareholders entitled to vote who are present, in person or by proxy, at the meeting. Each director shall be appointed and elected for such term as the resolution appointing him or her may determine or until his or her removal or vacation of office in accordance with the Articles of Association.

Any vacancies on the board of directors that arise other than upon the removal of a director by resolution passed at a general meeting can be filled by the remaining directors (notwithstanding that they may constitute less than a quorum). Any such appointment shall be as an interim director to fill such vacancy until the next annual general meeting of shareholders.

Additions to the existing board (within the limits set pursuant to the Articles of Association) may be made by ordinary resolution of the shareholders.

#### Grounds for Removing a Director
A director may be removed with or without cause by ordinary resolution. The notice of general meeting must contain a statement of the intention to remove the director and must be served on the director not less than ten calendar days before the meeting. The director is entitled to attend the meeting and be heard on the motion for his removal.

The office of a director will be vacated automatically if he or she (1) becomes prohibited by law from being a director, (2) becomes bankrupt or makes an arrangement or composition with his creditors, (3) dies or is in the opinion of all his co-directors, incapable by reason of mental disorder of discharging his duties as director, (4) resigns his office by notice to us or (5) has for more than six months been absent without permission of the directors from meetings of the board of directors held during that period, and the remaining directors resolve that his or her office be vacated.

#### Proceedings of the Board of Directors
The Articles of Association provide that Arco's business is to be managed and conducted by the board of directors. The quorum necessary for the board meeting shall be a simple majority of the directors then in office (subject to there being a minimum of two directors present) and business at any meeting shall be decided by a majority of votes. In the case of an equality of votes, the chairman shall have a casting vote.

Subject to the provisions of the Articles of Association, the board of directors may regulate its proceedings as they determine is appropriate. Board meetings shall be held at least once every calendar quarter and shall take place either in São Paulo, Brazil, or at such other place as the directors may determine.

Subject to the provisions of the Articles of Association, to any directions given by ordinary resolution of the shareholders and the listing rules of the Nasdaq, the board of directors may from time to time at its discretion exercise all powers of Arco, including, subject to the Companies Act, the power to issue debentures, bonds and other securities of the company, whether outright or as collateral security for any debt, liability or obligation of our company or of any third party.

#### Inspection of Books and Records
Holders of Arco shares will have no general right under Cayman Islands law to inspect or obtain copies of the list of shareholders or corporate records of the Company. However, the board of directors may determine from time to time whether and to what extent Arco's accounting records and books shall be open to inspection by shareholders who are not members of the board of directors. Notwithstanding the above, the Articles of Association provide shareholders with the right to receive annual financial statements. Such right to receive annual financial statements may be satisfied by publishing the same on the company's website or filing such annual reports as we are required to file with the SEC.

[**Table of Contents**](#TOC)

#### Register of Shareholders
The Class A common shares are held through DTC, and DTC or Cede & Co., as nominee for DTC, will be recorded in the shareholders' register as the holder of our Class A common shares.

Under Cayman Islands law, Arco must keep a register of shareholders that includes:

● the names and addresses of the shareholders, a statement of the shares held by each member, and of the amount paid or agreed to be considered as paid, on the shares of each member;

● whether voting rights attach to the shares in issue;

● the date on which the name of any person was entered on the register as a member; and

● the date on which any person ceased to be a member.

Under Cayman Islands law, the register of shareholders of Arco is *prima facie* evidence of the matters set out therein (i.e., the register of shareholders will raise a presumption of fact on the matters referred to above unless rebutted) and a shareholder registered in the register of shareholders is deemed as a matter of Cayman Islands law to have *prima facie* legal title to the shares as set against his or her name in the register of shareholders. Once the register of shareholders has been updated, the shareholders recorded in the register of shareholders should be deemed to have legal title to the shares set against their name.

However, there are certain limited circumstances where an application may be made to a Cayman Islands court for a determination on whether the register of members reflects the correct legal position. Further, the Cayman Islands court has the power to order that the register of members maintained by a company should be rectified where it considers that the register of members does not reflect the correct legal position. If an application for an order for rectification of the register of members were made in respect of our common shares, then the validity of such shares may be subject to re-examination by a Cayman Islands court.

#### Exempted Company
Arco is an exempted company with limited liability under the Companies Act. The Companies Act distinguishes between ordinary resident companies and exempted companies. Any company that is registered in the Cayman Islands but conducts business mainly outside of the Cayman Islands may apply to be registered as an exempted company. The requirements for an exempted company are essentially the same as for an ordinary company except for the exemptions and privileges listed below:

● an exempted company does not have to file an annual return of its shareholders with the Registrar of Companies;

● an exempted company's register of shareholders is not open to inspection;

● an exempted company does not have to hold an annual general meeting;

● an exempted company may issue shares with no par value;

● an exempted company may obtain an undertaking against the imposition of any future taxation (such undertakings are usually given for 20 years in the first instance);

● an exempted company may register by way of continuation in another jurisdiction and be deregistered in the Cayman Islands;

● an exempted company may register as a limited duration company; and

● an exempted company may register as a segregated portfolio company.

[**Table of Contents**](#TOC)

"Limited liability" means that the liability of each shareholder is limited to the amount unpaid by the shareholder on the shares of the company (except in exceptional circumstances, such as involving fraud, the establishment of an agency relationship or an illegal or improper purpose or other circumstances in which a court may be prepared to pierce or lift the corporate veil).

Arco is subject to reporting and other informational requirements of the Exchange Act, as applicable to foreign private issuers. Except as otherwise disclosed in this annual report, Arco intends to continue to comply with the Nasdaq rules in lieu of following home country practice.

#### Anti-Takeover Provisions in our Articles of Association
Some provisions of the Articles of Association may discourage, delay or prevent a change in control of Arco or management that shareholders may consider favorable. In particular, the capital structure of Arco concentrates ownership of voting rights in the hands of the Founding Shareholders. These provisions, which are summarized below, are expected to discourage coercive takeover practices and inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of Arco to first negotiate with the board of directors. However, these provisions could also have the effect of discouraging others from attempting hostile takeovers and, as a consequence, they may also inhibit temporary fluctuations in the market price of the Class A common shares that often result from actual or rumored hostile takeover attempts. These provisions may also have the effect of preventing changes in the management of Arco. It is possible that these provisions could make it more difficult to accomplish transactions that shareholders may otherwise deem to be in their best interests.

#### Two Classes of Common Shares
The Class B common shares of Arco are entitled to 10 votes per share, while the Class A common shares are entitled to one vote per share. Since it owns of all of the Class B common shares of Arco, the Founding Shareholders currently have the ability to elect all directors and to determine the outcome of most matters submitted for a vote of shareholders. This concentrated voting control could discourage others from initiating any potential merger, takeover, or other change of control transaction that other shareholders may view as beneficial.

So long as the Founding Shareholders have the ability to determine the outcome of most matters submitted to a vote of shareholders, third parties may be deterred in their willingness to make an unsolicited merger, takeover, or other change of control proposal, or to engage in a proxy contest for the election of directors. As a result, the fact that Arco has two classes of common shares may have the effect of depriving you as a holder of Class A common shares of an opportunity to sell your Class A common shares at a premium over prevailing market prices and make it more difficult to replace the directors and management of Arco.

#### Preferred Shares
Arco's board of directors is given wide powers to issue one or more classes or series of shares with preferred rights. Such preferences may include, for example, dividend rights, conversion rights, redemption privileges, enhanced voting powers and liquidation preferences.

Despite the anti-takeover provisions described above, under Cayman Islands law, Arco's board of directors may only exercise the rights and powers granted to them under the Articles of Association, for what they believe in good faith to be in the best interests of Arco.

#### Protection of Non-Controlling Shareholders
The Grand Court of the Cayman Islands may, on the application of shareholders holding not less than one-fifth of the shares of Arco in issue, appoint an inspector to examine the Company's affairs and report thereon in a manner as the Grand Court shall direct.

Subject to the provisions of the Companies Act, any shareholder may petition the Grand Court of the Cayman Islands which may make a winding-up order, if the court is of the opinion that this winding up is just and equitable.

[**Table of Contents**](#TOC)

Notwithstanding the U.S. securities laws and regulations that are applicable to Arco, general corporate claims against Arco by its shareholders must, as a general rule, be based on the general laws of contract or tort applicable in the Cayman Islands or their individual rights as shareholders as established by Arco's Articles of Association.

The Cayman Islands courts ordinarily would be expected to follow English case law precedents, which permit a minority shareholder to commence a representative action against Arco, or derivative actions in Arco's name, to challenge (1) an act which is *ultra vires* or illegal, (2) an act which constitutes a fraud against the minority and the wrongdoers themselves control Arco, and (3) an irregularity in the passing of a resolution that requires a qualified (or special) majority.

#### Registration Rights and Restricted Shares
Although no shareholders of Arco have formal registration rights, they or entities controlled by them or their permitted transferees will be able to sell their shares in the public market from time to time pursuant to an exemption from registration, subject to certain limitations on the timing, amount and method of those sales imposed by regulations promulgated by the SEC.

C. Material contracts

See "Item 7. Major Shareholders and Related Party Transactions—B. Related party transactions." Except as otherwise disclosed in this annual report on Form 20-F (including the exhibits hereto), we are not currently, and have not been in the last two years, party to any material contract, other than contracts entered into in the ordinary course of business.

D. Exchange controls

The Cayman Islands currently has no exchange control restrictions.

E. Taxation

The following summary contains a description of certain Cayman Islands and U.S. federal income tax consequences of the acquisition, ownership and disposition of our Class A common shares. It does not purport to be a comprehensive description of all the tax considerations that may be relevant to a decision to purchase the Class A common shares, is not applicable to all categories of investors, some of which may be subject to special rules, and does not address all of the Cayman Islands and U.S. federal income tax considerations applicable to any particular holder. The summary is based upon the tax laws of the Cayman Islands and regulations thereunder and on the tax laws of the United States and regulations thereunder as of the date hereof, which are subject to change.

Prospective purchasers of our Class A common shares should consult their own tax advisors about the particular Cayman Islands and U.S. federal, state, local and other tax consequences to them of the acquisition, ownership and disposition of our Class A common shares.

#### Cayman Islands Tax Considerations
The Cayman Islands laws currently levy no taxes on individuals or corporations based upon profits, income, gains or appreciation and there is no taxation in the nature of inheritance tax or estate duty or withholding tax applicable to us or to any holder of Class A common shares. There are no other taxes likely to be material to us levied by the government of the Cayman Islands except for stamp duties which may be applicable on instruments executed in, or after execution brought within the jurisdiction of the Cayman Islands. No stamp duty is payable in the Cayman Islands on transfers of shares of Cayman Islands companies except those which hold interests in land in the Cayman Islands. The Cayman Islands is not party to any double tax treaties which are applicable to any payments made by or to our company. There are no exchange control regulations or currency restrictions in the Cayman Islands.

As a Cayman Islands exempted company with limited liability, we have received an undertaking as to tax concessions pursuant to Section 6 of the Tax Concessions Act (As Revised). This undertaking provides that, for a period of 20 years from the date of issue of the undertaking (April 16, 2018), no law thereafter enacted in the Cayman Islands imposing any taxes to be levied on profits, income, gains or appreciation will apply to us or our operations.

[**Table of Contents**](#TOC)

Payments of dividends and capital in respect of our Class A common shares will not be subject to taxation in the Cayman Islands and no withholding will be required on the payment of a dividend or capital to any holder of our Class A common shares, nor will gains derived from the disposal of our Class A common shares be subject to Cayman Islands income or corporation tax.

There is no income tax treaty or convention currently in effect between the United States and the Cayman Islands.

#### Material U.S. Federal Income Tax Considerations for U.S. Holders
The following summary describes the material U.S. federal income tax consequences of the ownership and disposition of our Class A common shares, but it does not purport to be a comprehensive description of all of the tax considerations that may be relevant to a particular person's decision to hold such securities.

This summary applies only to U.S. Holders (as defined below) that hold our Class A common shares as capital assets for tax purposes. In addition, it does not describe all of the tax consequences that may be relevant in light of a U.S. Holder's particular circumstances, including alternative minimum tax consequences, the potential application of the provisions of the Internal Revenue Code of 1986, as amended (the "Code"), known as the Medicare contribution tax, and tax consequences applicable to U.S. Holders subject to special rules, such as:

● certain financial institutions;

● insurance companies;

● real estate investment trusts or regulated investment companies;

● dealers or traders in securities that use a mark-to-market method of tax accounting;

● persons holding common shares as part of a hedging transaction, straddle, wash sale, conversion transaction or other integrated transaction or persons entering into a constructive sale with respect to the common shares;

● persons whose functional currency for U.S. federal income tax purposes is not the U.S. dollar;

● tax-exempt entities, including an "individual retirement account" or "Roth IRA;"

● persons that own or are deemed to own ten percent or more of our Class A common shares, by vote or value;

● persons holding our Class A common shares in connection with a trade or business conducted outside of the United States; or

● partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes.

If an entity that is classified as a partnership for U.S. federal income tax purposes holds our Class A common shares, the U.S. federal income tax treatment of a partner will generally depend on the status of the partner and the activities of the partnership. Partnerships holding our Class A common shares and partners in such partnerships should consult their tax advisers as to the particular U.S. federal income tax consequences of owning and disposing of the Class A common shares.

This discussion is based on the Code, administrative pronouncements, judicial decisions, final, temporary and proposed Treasury regulations, all as of the date hereof, any of which is subject to change or differing interpretations, possibly with retroactive effect.

A "U.S. Holder" is a holder who, for U.S. federal income tax purposes, is a beneficial owner of our Class A common shares and is:

● an individual that is a citizen or resident of the United States;

[**Table of Contents**](#TOC)

● a corporation, or other entity taxable as a corporation, created or organized in or under the laws of the United States, any state therein or the District of Columbia; or

● an estate or trust the income of which is subject to U.S. federal income taxation regardless of its source.

U.S. Holders should consult their tax advisors concerning the U.S. federal, state, local and non-U.S. tax consequences of owning and disposing of our Class A common shares in their particular circumstances.

This discussion assumes that we are not, and will not become, a passive foreign investment company (a "PFIC"), as described below.

#### Taxation of Distributions
As discussed under "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—Dividends and Dividend Policy", we do not currently intend to pay dividends. In the event that we do pay dividends, and subject to the discussion below under "—Passive Foreign Investment Company Rules," distributions paid on our Class A common shares, other than certain pro rata distributions of common shares, will be treated as dividends to the extent paid out of our current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Because we do not maintain calculations of our earnings and profits under U.S. federal income tax principles, we expect that distributions generally will be reported to U.S. Holders as dividends. Subject to applicable limitations, dividends paid to certain non-corporate U.S. Holders may be eligible for taxation as "qualified dividend income" and therefore may be taxable at rates applicable to long-term capital gains so long as our Class A common shares are listed and trade on Nasdaq or are readily tradable on another established securities market in the United States. U.S. Holders should consult their tax advisors regarding the availability of the reduced tax rate on dividends in their particular circumstances.

The amount of the dividend will generally be treated as foreign-source dividend income to U.S. Holders and will not be eligible for the dividends-received deduction generally available to U.S. corporations under the Code. Dividends will be included in a U.S. Holder's income on the date of the U.S. Holder's receipt of the dividend.

#### Sale or Other Disposition of Common Shares
Subject to the discussion below under "—Passive Foreign Investment Company Rules," for U.S. federal income tax purposes, gain or loss realized on the sale or other disposition of our Class A common shares will be capital gain or loss and will be long-term capital gain or loss if the U.S. Holder held the Class A common shares for more than one year. The amount of the gain or loss will equal the difference between the U.S. Holder's tax basis in the Class A common shares disposed of and the amount realized on the disposition, in each case as determined in U.S. dollars. This gain or loss will generally be U.S.-source gain or loss for foreign tax credit purposes. The deductibility of capital losses is subject to various limitations.

#### Passive Foreign Investment Company Rules
A non-U.S. corporation will be a PFIC for any taxable year in which either (i) 75% or more of its gross income consists of "passive income," or (ii) 50% or more of the average quarterly value of its assets consist of assets that produce, or are held for the production of, "passive income." For this purpose, subject to certain exceptions, passive income includes interest, dividends, rents, and gains from transactions in commodities. A non-U.S. corporation will be treated as owning its proportionate share of the assets and earning its proportionate share of the income of any other corporation in which it owns, directly or indirectly, at least 25% (by value) of the stock.

Based on our current operations, income, assets and certain estimates and projections, including as to the relative values of our assets, we believe that we were not a PFIC for U.S. federal income tax purposes for our taxable year ended December 31, 2022. However, because PFIC status depends on the composition of a company's income and assets and the market value of its assets from time to time, there can be no assurance that we will not be a PFIC for any taxable year. If we were a PFIC for any year during which a U.S. Holder holds our Class A common shares, we generally would continue to be treated as a PFIC with respect to that U.S.

[**Table of Contents**](#TOC)

Holder for all succeeding years during which the U.S. Holder holds the Class A common shares, even if we ceased to meet the threshold requirements for PFIC status.

If we were a PFIC for any taxable year during which a U.S. Holder held our Class A common shares (assuming such U.S. Holder has not made a timely election described below), gain recognized by a U.S. Holder on a sale or other disposition (including certain pledges) of the Class A common shares would be allocated ratably over the U.S. Holder's holding period for the Class A common shares. The amounts allocated to the taxable year of the sale or other disposition and to any year before we became a PFIC would be taxed as ordinary income. The amount allocated to each other taxable year would be subject to tax at the highest rate in effect for individuals or corporations, as appropriate, for that taxable year, and an interest charge would be imposed on the tax on such amount. Further, to the extent that any distribution received by a U.S. Holder on its Class A common shares exceeds 125% of the average of the annual distributions on such common shares received during the preceding three years or the U.S. Holder's holding period, whichever is shorter, that distribution would be subject to taxation in the same manner as gain, described immediately above. If we are a PFIC in any year, certain elections may be available that would result in alternative tax consequences (such as mark-to-market treatment) of owning and disposing the Class A common shares. U.S. Holders should consult their tax advisers to determine whether any of these elections would be available and, if so, what the consequences of the alternative treatments would be in their particular circumstances.

In addition, if we were a PFIC or, with respect to a particular U.S. Holder, were treated as a PFIC for the taxable year in which we paid a dividend or for the prior taxable year, the preferential dividend rates discussed above with respect to dividends paid to certain non-corporate U.S. Holders would not apply.

If a U.S. Holder owns Class A common shares during any year in which we are a PFIC, the holder generally must file an annual report containing such information as the U.S. Treasury may require on IRS Form 8621 (or any successor form) with respect to us, generally with the holder's federal income tax return for that year.

U.S. Holders should consult their tax advisors concerning our potential PFIC status and the potential application of the PFIC rules.

#### Information Reporting and Backup Withholding
Payments of dividends and sales proceeds that are made within the United States or through certain U.S.-related financial intermediaries generally are subject to information reporting, and may be subject to backup withholding, unless (i) the U.S. Holder is a corporation or other exempt recipient or (ii) in the case of backup withholding, the U.S. Holder provides a correct taxpayer identification number and certifies that it is not subject to backup withholding.

Backup withholding is not an additional tax. The amount of any backup withholding from a payment to a U.S. Holder will be allowed as a credit against such holder's U.S. federal income tax liability and may entitle it to a refund, provided that the required information is timely furnished to the IRS. U.S. Holders should consult their tax advisers regarding the application of the U.S. information reporting and backup withholding rules.

#### Information with Respect to Foreign Financial Assets
Certain U.S. Holders who are individuals (and, under Treasury regulations, certain entities) may be required to report information on their U.S. federal income tax returns relating to an interest in our common shares, subject to certain exceptions (including an exception for common shares held in accounts maintained by certain U.S. financial institutions).

U.S. Holders should consult their tax advisors regarding the effect, if any, of this requirement on their ownership and disposition of the common shares.

#### ITEM 11. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
We are exposed to market risks associated with foreign exchange and interest rates. In accordance with our policies, we seek to manage our exposure to these various market-based risks.

We monitor market, credit and operational risks in line with the objectives in capital management, supported by the oversight of our Board of Directors, in decisions related to capital management and to ensure their consistency with our objectives and assessment of risks. Information relating to quantitative and qualitative disclosures about these market risks is described below.

#### Foreign Exchange Risk
The Company's exposure to foreign currency risks of December 31, 2022 consists of cash and cash equivalents and financial investments and borrowings denominated in U.S. dollars in the amount of R$14.1 million and R$654.5 million, respectively. See note 27 to our audited consolidated financial statements for a sensitivity analysis of the impact of a hypothetical 10% change in the exchange rate variation on our cash and cash equivalents and financial investments as of December 31, 2022.

#### Liquidity Risk
We regularly review the liquidity risk and maintain appropriate reserves, including bank credit facilities with first tier financial institutions. We also continuously monitor projected and actual cash flows and the combination of maturity profiles of the financial assets and liabilities.

[**Table of Contents**](#TOC)

The main requirements for financial resources used by us arise from the need to make payments for printing educational content, freight expenses, operating expenses, labor and social obligations and other operating disbursements. The following is a summary of our contractual obligations as of December 31, 2022:

---

| | | | |
|:---|:---|:---|:---|
| <br>**December 31, 2022** | **Less than**<br>**3 months** | **More than**<br>**5 years** | <br>**Total** |

| **Total** | **728.2** | **733.5** | **3701.5** |

---

For more information, see note 27 to our audited consolidated financial statements included elsewhere in this annual report.

#### Financial Counterparty Risk
The financial counterparty risk arises from the possibility that we may incur losses due to the default of our counterparties. We adopt as practice the analysis of the financial and equity situation of our counter parts in order to control this risk.

Counterparty credit limits, which take published credit ratings and other factors into account, are set to cover our total aggregate exposure to a single financial institution. Exposures and limits applicable to each financial institution are approved by our treasury within guidelines approved by the board and are reviewed on a regular basis.

#### Interest Rate Risk
Interest rate risk represents the exposure to changes in the fair value or future cash flows of a financial instrument from fluctuations due to changes in market interest rates. Our exposure to this risk relates primarily to our investments with floating interest rates. We are primarily exposed to the fluctuation of the CDI rate on financial investments. Our exposure to cash, bank deposits and cash equivalents and financial investments indexed to the CDI rate totaled R$2,710.9 million as of December 31, 2022. See note 27 to our audited consolidated financial statements for further information on our market risks, including a sensitivity analysis of the impact of a hypothetical 10% change in the CDI rate on our cash and cash equivalents and financial investments as of December 31, 2022.

We have evaluated, with the participation of our chief executive officer and chief financial officer, the effectiveness of our "disclosure controls and procedures," as such term is defined in Rule 13a-15(e) and 15d-15(e) of the Exchange Act, as of December 31, 2022. There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives. Based upon our evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective as of December 31, 2022 to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

B. Management's annual report on internal control over financial reporting

Management is responsible for establishing and maintaining adequate "internal control over financial reporting," as such term is defined in Rule 13a-15(f) of the Exchange Act. Internal control over financial reporting is a process designed by, or under the supervision of, our chief executive officer and chief financial officer and effected by our Board of Directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatement. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2022. In making its assessment of internal control over financial reporting, management used the criteria described in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

C. Attestation report of the registered public accounting firm

The effectiveness of internal control over financial reporting as of December 31, 2022, has been audited by Ernst & Young Auditores Independentes S.S. Ltda., or EY, an independent registered public accounting firm, as stated in its report which is included under Item 18 in this annual report on Form 20-F on page F-6.

D. Changes in internal control over financial reporting

There has been no change in our internal control over financial reporting during 2022 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

#### ITEM 16G. CORPORATE GOVERNANCE

#### Foreign Private Issuer Status
Nasdaq listing rules include certain accommodations in the corporate governance requirements that allow foreign private issuers, such as us, to follow "home country" corporate governance practices in lieu of the otherwise applicable corporate governance standards of Nasdaq. The application of such exceptions requires that we disclose each noncompliance with Nasdaq listing rules that we do not follow and describe the Cayman Islands corporate governance practices we do follow in lieu of the relevant Nasdaq corporate governance standard. As a foreign private issuer, we currently rely, and will continue to rely, on the foreign private issuer exemption with respect to the following rules:

● Nasdaq Rule 5605(b), which requires that independent directors comprise a majority of a company's board of directors. Laws of the Cayman Islands allow that independent directors do not comprise a majority of our board of directors. As of the date of this annual report, our independent directors comprise the majority of our board of directors;

● Nasdaq Rule 5605I(1), which requires that a company have a nominations committee comprised solely of "independent directors" as defined by Nasdaq. As allowed by the laws of the Cayman Islands, we do not have a nominations committee nor do we have any current intention to establish one;

● Nasdaq Rule 5605(d) & (e), which require that compensation for our executive officers and selection of our director nominees be determined by a majority of independent directors. As allowed by the laws of the Cayman Islands, we do not have (i) a nomination and corporate governance committee; or (ii) a remuneration committee that meets the requirements of Nasdaq Rule 5605(d) & (e), nor do we have any current intention to establish either; and

● Nasdaq Rule 5635, which requires that a listed issuer obtain shareholder approval prior to an issuance of securities in connection with: (i) the acquisition of the stock or assets of another company; (ii) equity-based compensation of officers, directors, employees or consultants; (iii) a change of control; and (iv) transactions other than public offerings. Pursuant to the laws of the Cayman Islands and our Articles of Association, we are not required to obtain any such approval.

[**Table of Contents**](#TOC)

#### Principal Differences between Cayman Islands and U.S. Corporate Law
The Companies Act was modeled originally after similar laws in England and Wales but does not follow subsequent statutory enactments in England and Wales. In addition, the Companies Act differs from laws applicable to U.S. corporations and their shareholders. Set forth below is a summary of the significant differences between the provisions of the Companies Act applicable to Arco and the laws applicable to companies incorporated in the United States and their shareholders.

#### Mergers and Similar Arrangements
The Companies Act permits mergers or consolidations between two Cayman Islands companies and between Cayman Islands companies, or between a Cayman Islands company and a company incorporated in another jurisdiction (provided that is facilitated by the laws of that other jurisdiction).

Where the merger or consolidation is between two Cayman Islands companies, the directors of each constituent company must approve a written plan of merger or consolidation, which must then be authorized by (a) a special resolution of the shareholders of each company; and (b) such other authorization, if any, as may be specified in such constituent company's Articles of Association. No shareholder resolution is required for a merger between a parent company (i.e., a company that owns at least 90% of the issued shares of each class in a subsidiary company) and its subsidiary company. The consent of each holder of a fixed or floating security interest of a constituent company must be obtained, unless the court waives such requirement. If the Cayman Islands Registrar of Companies is satisfied that the requirements of the Companies Act (which includes certain other formalities) have been complied with, the Registrar of Companies will register the plan of merger or consolidation. Where the merger or consolidation involves a foreign company, the procedure is similar, save that with respect to the foreign company, the director of the Cayman Islands company is required to make a declaration to the effect that, having made due enquiry, he is of the opinion that the requirements set out below have been met: (i) that the merger or consolidation is permitted or not prohibited by the constitutional documents of the foreign company and by the laws of the jurisdiction in which the foreign company is incorporated, and that those laws and any requirements of those constitutional documents have been or will be complied with; (ii) that no petition or other similar proceeding has been filed and remains outstanding or order made or resolution adopted to wind up or liquidate the company in any foreign jurisdiction, (iii) that no receiver, trustee, administrator or other similar person has been appointed in any jurisdiction and is acting in respect of the foreign company, its affairs or property or any part thereof, (iv) that no scheme, order, compromise or similar arrangement has been entered into or made in any jurisdiction whereby the rights of creditors of the foreign company are and continue to be suspended or restricted.

Moreover, Cayman Islands law also has separate statutory provisions that facilitate the reconstruction or amalgamation of companies, in certain circumstances, schemes of arrangement will generally be more suited for complex mergers or other transactions involving widely held companies, commonly referred to in the Cayman Islands as a "scheme of arrangement" which may be tantamount to a merger. In the event that a merger was sought pursuant to a scheme of arrangement (the procedure of which are more rigorous and take longer to complete than the procedures typically required to consummate a merger in the United States), the arrangement in question is approved by each class of shareholders with whom the arrangement is to be made who must represent three-fourths in value of each such class of shareholders and a majority in number of each class of creditors with whom the arrangement is to be made, and who must in addition represent three-fourths in value of each such class of creditors, as the case may be, that are present and voting either in person or by proxy at a meeting, or meetings summoned for that purpose. The convening of the meetings and subsequently the terms of the arrangement must be sanctioned by the Grand Court of the Cayman Islands. While a dissenting shareholder would have the right to express to the court the view that the transaction should not be approved, the court can be expected to approve the arrangement if it satisfies itself that:

● Arco is not proposing to act illegally or beyond the scope of its corporate authority and the statutory provisions as to majority vote have been complied with;

● the shareholders have been fairly represented at the meeting in question;

● the arrangement is such as a businessman would reasonably approve; and

● the arrangement is not one that would more properly be sanctioned under some other provision of the Companies Act or that would amount to a "fraud on the minority."

[**Table of Contents**](#TOC)

If a scheme of arrangement or takeover offer (as described below) is approved, any dissenting shareholder would have no rights comparable to appraisal rights, which would otherwise ordinarily be available to dissenting shareholders of United States corporations, providing rights to receive payment in cash for the judicially determined value of the shares.

#### Squeeze-out Provisions
When a takeover offer is made and accepted by holders of 90.0% of the shares to whom the offer is made within four months, the offeror may, within a two-month period, require the holders of the remaining shares to transfer such shares on the terms of the offer. An objection may be made to the Grand Court of the Cayman Islands but is unlikely to succeed unless there is evidence of fraud, bad faith, collusion or inequitable treatment of the shareholders.

Further, transactions similar to a merger, reconstruction and/or an amalgamation may in some circumstances be achieved through other means to these statutory provisions, such as a share capital exchange, asset acquisition or control, through contractual arrangements, of an operating business.

#### Shareholders' Suits
Maples and Calder (Cayman) LLP, our Cayman Islands counsel is not aware of any reported class action having been brought in a Cayman Islands court. Derivative actions have been brought in the Cayman Islands courts, and the Cayman Islands courts have confirmed the availability for such actions. In most cases, we will be the proper plaintiff in any claim based on a breach of duty owed to us, and a claim against (for example) our officers or directors usually may not be brought by a shareholder. However, based on English authorities, which would in all likelihood be of persuasive authority and be applied by a court in the Cayman Islands, exceptions to the foregoing principle apply in circumstances in which:

● a company is acting or proposing to act illegally or beyond the scope of its authority;

● the act complained of, although not beyond the scope of the authority, could be effected if duly authorized by more than the number of votes which have actually been obtained; and

● those who control the company are perpetrating a "fraud on the minority."

A shareholder may have a direct right of action against us where the individual rights of that shareholder have been infringed or are about to be infringed.

#### Corporate Governance
Cayman Islands law restricts transactions between a company and its directors unless there are provisions in the Articles of Association which provide a mechanism to alleviate possible conflicts of interest. Additionally, Cayman Islands law imposes on directors' duties of care and skill and fiduciary duties to the companies which they serve. Under Arco's Articles of Association, a director must disclose the nature and extent of his interest in any contract or arrangement and following such disclosure and subject to any separate requirement under applicable law or the listing rules of the Nasdaq, and unless disqualified by the chairman of the relevant meeting, the interested director may vote in respect of any transaction or arrangement in which he or she is interested. The interested director shall be counted in the quorum at such meeting and the resolution may be passed by a majority of the directors present at the meeting.

Subject to the foregoing and our Articles of Association, our directors may exercise all the powers of Arco to vote compensation to themselves or any member of their body in the absence of an independent quorum. Our Articles of Association provide that, in the event a Compensation Committee is established, it shall be made up of such number of independent directors as is required from time to time by the Nasdaq rules (or as otherwise may be required by law).

As a foreign private issuer, we are permitted to follow home country practice in lieu of certain Nasdaq corporate governance rules, subject to certain requirements. We currently rely, and will continue to rely, on the foreign private issuer exemption with respect to the following rules:

● Nasdaq Rule 5605(b), which requires that independent directors comprise a majority of a company's board of directors. As of the date of this annual report, independent directors do comprise a majority of our board of directors;

[**Table of Contents**](#TOC)

● Nasdaq Rule 5605(e)(1), which requires that a company have a nominations committee comprised solely of "independent directors" as defined by Nasdaq. As allowed by the laws of the Cayman Islands, we do not have a nominations committee nor do we have any current intention to establish one;

● Nasdaq Rule 5605(d) & (e), which require that compensation for our executive officers and selection of our director nominees be determined by a majority of independent directors. As allowed by the laws of the Cayman Islands, we do not have (i) a nomination and corporate governance committee; or (ii) a remuneration committee that meets the requirements of Nasdaq Rule 5605(d) & (e), nor do we have any current intention to establish either; and

● Nasdaq Rule 5635, which requires that a listed issuer obtain shareholder approval prior to an issuance of securities in connection with: (i) the acquisition of the stock or assets of another company; (ii) equity-based compensation of officers, directors, employees or consultants; (iii) a change of control; and (iv) transactions other than public offerings. Pursuant to the laws of the Cayman Islands and our Articles of Association, we are not required to obtain any such approval.

#### Borrowing Powers
Arco's directors may exercise all the powers of Arco to borrow money and to mortgage or charge its undertaking, property and assets (present and future) and uncalled capital or any part thereof and to issue debentures, debenture stock, mortgages, bonds and other such securities whether outright or as security for any debt, liability or obligation of Arco or of any third-party. Such powers may be varied by a special resolution of shareholders (requiring a two-thirds majority vote).

#### Indemnification of Directors and Executive Officers and Limitation of Liability
The Companies Act does not limit the extent to which a company's Articles of Association may provide for indemnification of directors and officers, except to the extent that it may be held by the Cayman Islands courts to be contrary to public policy, such as to provide indemnification against civil fraud or the consequences of committing a crime. Arco's Articles of Association provide that we shall indemnify and hold harmless our directors and officers against all actions, proceedings, costs, charges, expenses, losses, damages, liabilities, judgments, fines, settlements and other amounts incurred or sustained by such directors or officers, other than by reason of such person's dishonesty, willful default or fraud, in or about the conduct of our company's business or affairs (including as a result of any mistake of judgment) or in the execution or discharge of his duties, powers, authorities or discretions, including without prejudice to the generality of the foregoing, any costs, expenses, losses or liabilities incurred by such director or officer in defending (whether successfully or otherwise) any civil, criminal or other proceedings concerning Arco or our affairs in any court whether in the Cayman Islands or elsewhere. This standard of conduct is generally the same as permitted under the Delaware General Corporation Law for a Delaware corporation.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to Arco's directors, officers or persons controlling the Company under the foregoing provisions, we have been informed that, in the opinion of the SEC, this indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

[**Table of Contents**](#TOC)

#### Directors' Fiduciary Duties
As a matter of Cayman Islands law, a director of a Cayman Islands company is in the position of a fiduciary with respect to the company. Accordingly, directors and officers owe the following fiduciary duties (1) duty to act in good faith in what the director or officer believes to be in the best interests of the company as a whole; (2) duty to exercise powers for the purposes for which those powers were conferred and not for a collateral purpose; (3) directors should not improperly fetter the exercise of future discretion; (4) duty to exercise powers fairly as between different sections of shareholders; (5) duty to exercise independent judgment; and (6) duty not to put themselves in a position in which there is a conflict between their duty to the company and their personal interests. However, this obligation may be varied by the company's Articles of Association, which may permit a director to vote on a matter in which he has a personal interest provided that he has disclosed that nature of his interest to the board of directors. With respect to the duty of directors to avoid conflicts of interest, Arco's Articles of Association vary from the applicable provisions of Cayman Islands law mentioned above by providing that a director must disclose the nature and extent of his or her interest in any contract or arrangement, and following such disclosure and subject to any separate requirement under applicable law or the listing rules of the Nasdaq, and unless disqualified by the chairman of the relevant meeting, such director may vote in respect of any transaction or arrangement in which he or she is interested and may be counted in the quorum at the meeting. In addition to the above, under Cayman Islands law, directors also owe a duty of care which is not fiduciary in nature. This duty has been defined as a requirement to act as a reasonably diligent person having both the general knowledge, skill and experience that may reasonably be expected of a person carrying out the same functions as are carried out by that director in relation to the company and the general knowledge skill and experience which that director has. As set out above, directors have a duty not to put themselves in a position of conflict and this includes a duty not to engage in self-dealing, or to otherwise benefit as a result of their position. However, in some instances what would otherwise be a breach of this duty can be forgiven and/or authorized in advance by the shareholders provided that there is full disclosure by the directors. This can be done by way of permission granted in the memorandum and articles of association or alternatively by shareholder approval at general meetings.

A director of a Cayman Islands company also owes to the company duties to exercise independent judgment in carrying out his functions and to exercise reasonable skill, care and diligence, which has both objective and subjective elements. Recent Cayman Islands case law confirmed that directors must exercise the care, skill and diligence that would be exercised by a reasonably diligent person having the general knowledge, skill and experience reasonably to be expected of a person acting as a director. Additionally, a director must exercise the knowledge, skill and experience which he or she actually possesses.

A general notice may be given to the board of directors to the effect that (1) the director is a member or officer of a specified company or firm and is to be regarded as interested in any contract or arrangement which may after the date of the notice be made with that company or firm; or (2) he or she is to be regarded as interested in any contract or arrangement which may after the date of the notice to the board of directors be made with a specified person who is connected with him or her, will be deemed sufficient declaration of interest. This notice shall specify the nature of the interest in question. Following the disclosure being made pursuant to Arco's Articles of Association and subject to any separate requirement under applicable law or the listing rules of the Nasdaq, and unless disqualified by the chairman of the relevant meeting, a director may vote in respect of any transaction or arrangement in which he or she is interested and may be counted in the quorum at the meeting.

In comparison, under Delaware corporate law, a director of a Delaware corporation has a fiduciary duty to the corporation and its shareholders. This duty has two components: the duty of care and the duty of loyalty. The duty of care requires that a director act in good faith, with the care that an ordinarily prudent person would exercise under similar circumstances. Under this duty, a director must inform himself or herself of, and disclose to shareholders, all material information reasonably available regarding a significant transaction. The duty of loyalty requires that a director act in a manner he or she reasonably believes to be in the best interests of the corporation. He or she must not use his or her corporate position for personal gain or advantage. This duty prohibits self-dealing by a director and mandates that the best interest of the corporation and its shareholders take precedence over any interest possessed by a director, officer or controlling shareholder and not shared by the shareholders generally. In general, actions of a director are presumed to have been made on an informed basis, in good faith and in the honest belief that the action taken was in the best interests of the corporation. However, this presumption may be rebutted by evidence of a breach of one of the fiduciary duties. Should such evidence be presented concerning a transaction by a director, a director must prove the procedural fairness of the transaction, and that the transaction was of fair value to the corporation.

[**Table of Contents**](#TOC)

#### Shareholder Proposals
Under the Delaware General Corporation Law, a shareholder has the right to put any proposal before the annual meeting of shareholders, provided it complies with the notice provisions in the governing documents. The Delaware General Corporation Law does not provide shareholders an express right to put any proposal before the annual meeting of shareholders, but Delaware corporations generally afford shareholders an opportunity to make proposals and nominations provided that they comply with the notice provisions in the certificate of incorporation or bylaws. A special meeting may be called by the board of directors or any other person authorized to do so in the governing documents, but shareholders may be precluded from calling special meetings.

The Companies Act provides shareholders with only limited rights to requisition a general meeting and does not provide shareholders with any right to put any proposal before a general meeting. However, these rights may be provided in a company's Articles of Association. Arco's Articles of Association provide that upon the requisition of one or more shareholders representing not less than one-third of the voting rights entitled to vote at general meetings, the board will convene an extraordinary general meeting and put the resolutions so requisitioned to a vote at such meeting. The Articles of Association provide no other right to put any proposals before annual general meetings or extraordinary general meetings.

#### Cumulative Voting
Under the Delaware General Corporation Law, cumulative voting for elections of directors is not permitted unless the corporation's certificate of incorporation specifically provides for it. Cumulative voting potentially facilitates the representation of minority shareholders on a board of directors since it permits the minority shareholder to cast all the votes to which the shareholder is entitled on a single director, which increases the shareholder's voting power with respect to electing such director. As permitted under Cayman Islands law, Arco's Articles of Association do not provide for cumulative voting. As a result, the shareholders of Arco are not afforded any less protections or rights on this issue than shareholders of a Delaware corporation.

#### Removal of Directors
The office of a director shall be vacated automatically if, among other things, he or she (1) becomes prohibited by law from being a director, (2) becomes bankrupt or makes an arrangement or composition with his creditors, (3) dies or is in the opinion of all his co-directors, incapable by reason of mental disorder of discharging his duties as director (4) resigns his office by notice to us or (5) has for more than six months been absent without permission of the directors from meetings of the board of directors held during that period, and the remaining directors resolve that his/her office be vacated.

#### Transaction with Interested Shareholders
The Delaware General Corporation Law provides that; unless the corporation has specifically elected not to be governed by this statute, it is prohibited from engaging in certain business combinations with an "interested shareholder" for three years following the date that this person becomes an interested shareholder. An interested shareholder generally is a person or a group who or which owns or owned 15% or more of the target's outstanding voting shares or who or which is an affiliate or associate of the corporation and owned 15% or more of the corporation's outstanding voting shares within the past three years. This has the effect of limiting the ability of a potential acquirer to make a two-tiered bid for the target in which all shareholders would not be treated equally. The statute does not apply if, among other things, prior to the date on which the shareholder becomes an interested shareholder, the board of directors approves either the business combination or the transaction which resulted in the person becoming an interested shareholder. This encourages any potential acquirer of a Delaware corporation to negotiate the terms of any acquisition transaction with the target's board of directors.

Cayman Islands law has no comparable statute. As a result, Arco cannot avail itself of the types of protections afforded by the Delaware business combination statute. However, although Cayman Islands law does not regulate transactions between a company and its significant shareholders, it does provide that the board of directors owe duties to ensure that these transactions are entered into bona fide in the best interests of the company and for a proper corporate purpose and, as noted above, a transaction may be subject to challenge if it has the effect of constituting a fraud on the minority shareholders.

[**Table of Contents**](#TOC)

#### Dissolution; Winding Up
Under the Delaware General Corporation Law, unless the board of directors approves the proposal to dissolve, dissolution must be approved by shareholders holding 100% of the total voting power of the corporation. If the dissolution is initiated by the board of directors, it may be approved by a simple majority of the corporation's outstanding shares. Delaware law allows a Delaware corporation to include in its certificate of incorporation a supermajority voting requirement in connection with dissolutions initiated by the board. Under Cayman Islands law, a company may be wound up by either an order of the courts of the Cayman Islands or by a special resolution of its members or, if the company resolves by ordinary resolution that it be wound up because it is unable to pay its debts as they fall due. The court has authority to order winding up in a number of specified circumstances including where it is, in the opinion of the court, just and equitable to do so.

Under the Companies Act, Arco may be dissolved, liquidated or wound up by a special resolution of shareholders (requiring a two-thirds majority vote). Arco's Articles of Association also give its board of directors authority to petition the Cayman Islands Court to wind up Arco.

#### Variation of Rights of Shares
Under the Delaware General Corporation Law, a corporation may vary the rights of a class of shares with the approval of a majority of the outstanding shares of that class, unless the certificate of incorporation provides otherwise. Under Arco's Articles of Association, if the share capital is divided into more than one class of shares, the rights attached to any class may only be varied with the written consent of the holders of two-thirds of the shares of that class or the sanction of a special resolution passed at a separate meeting of the holders of the shares of that class.

Also, except with respect to share capital (as described above), alterations to Arco's Articles of Association may only be made by special resolution of shareholders (requiring a two-thirds majority vote).

#### Amendment of Governing Documents
Under the Delaware General Corporation Law, a corporation's certificate of incorporation may be amended only if adopted and declared advisable by the board of directors and approved by a majority of the outstanding shares entitled to vote, and the bylaws may be amended with the approval of a majority of the outstanding shares entitled to vote and may, if so provided in the certificate of incorporation, also be amended by the board of directors. Under Cayman Islands law, Arco's Articles of Association generally (and save for certain amendments to share capital described in this section) may only be amended by special resolution of shareholders (requiring a two-thirds majority vote).

#### Rights of Non-Resident or Foreign Shareholders
There are no limitations imposed by Arco's Articles of Association on the rights of non-resident or foreign shareholders to hold or exercise voting rights on Arco's shares. In addition, there are no provisions in the Articles of Association governing the ownership threshold above which shareholder ownership must be disclosed.

#### Handling of Mail
Mail addressed to us and received at our registered office will be forwarded unopened to the forwarding address, which will be supplied by us. None of us, our directors, officers, advisors or service providers (including the organization which provides registered office services in the Cayman Islands) will bear any responsibility for any delay howsoever caused in mail reaching the forwarding address.

**Management's Report on Internal Control over Financial Reporting**

Our management is responsible for establishing and maintaining adequate internal control over financial reporting and for assessing the effectiveness of internal control over financial reporting.

Our internal control over financial reporting is a process designed by, or under the supervision of, our chief executive officer and chief financial officer and effected by our board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our consolidated financial statements for external purposes in accordance with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB).

Due to its inherent limitations, internal control over financial reporting may not prevent or detect misstatement. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Our management has assessed the effectiveness of our internal control over financial reporting as of December 31, 2022, based upon the criteria described in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

Based on this assessment and criteria, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures were effective as of December 31, 2022 to provide reasonable assurance that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the applicable rules and forms, and that it is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

#### Report of Independent Registered Public Accounting Firm
To the Shareholders and the Board of Directors of

Arco Platform Limited

**Opinion on the Financial Statements**

We have audited the accompanying consolidated statements of financial position of Arco Platform Limited (the "Company") as of December 31, 2022 and 2021, the related consolidated statements of income and comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes (collectively referred to as the ''consolidated financial statements''). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board - IASB.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) and our report dated March 30, 2023 expressed an unqualified opinion thereon.

**Basis for Opinion**

These financial statements are the responsibility of the Company's Management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by Management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matters**

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) related to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgements. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

**Goodwill impairment testing**

---

| | |
|:---|:---|
| *Description of the Matter* | At December 31, 2022, the Company's goodwill was R$1,951 million. As discussed in Note 14 to the consolidated financial statements, goodwill is tested for impairment at least annually at the cash generating unit (CGU) level.<br>Auditing management's annual goodwill impairment test is complex and highly judgmental due to the significant estimation required to determine the fair value of the cash generating units. In particular, the fair value estimate is sensitive to significant assumptions, such as changes in the weighted average cost of capital, revenue growth rate, operating margin, costs, projected expenses and working capital, as well as the carrying amount of goodwill, which are affected by expectations about future economic scenarios, particularly those in emerging markets. |
| *How We Addressed the Matter in our audit* | We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company's accounting process for the goodwill impairment test including controls over management's review of the significant assumptions described above.<br>To test goodwill impairment our audit procedures included, among other, involving our valuation specialists to assist in evaluating the methodologies and key assumptions, including the estimated future gross margins, growth rate and the discount rate used in the valuation model. We also performed sensitivity analyses to understand the impact of reasonable changes in the key assumptions and compared those significant assumptions to the Company's industry and economic trends. Our procedures also consisted of testing the mathematical accuracy of the forecasts in the impairment assessment model and confirm whether Management's estimate of each CGU's recoverable amount considering the value in use calculation was based on a discounted cash flow model. We agreed the forecast cash flows to board-approved budgets and market communications and assessed the accuracy of prior period forecasts. We also evaluated the Company's disclosures in respect to its goodwill impairment assessment in Note 14. |

**Valuation of accounts payable to selling shareholders**

---

| | |
|:---|:---|
| *Description of the Matter* | At December 31, 2022, accounts payable to selling shareholders amounted to R$1,391 million, as disclosed in Note 17. Those amounts arise from certain business combinations and investments in associates. The determination of the recorded amounts includes the use of management assumptions about future business performance and interest rates.<br>Auditing accounts payable to selling shareholders was complex and required significant auditor judgement because of the high degree of subjectivity and judgment applied by management in the process of estimating the significant assumptions underlying the prospective financial information used in the determination of the recorded amounts. Those significant assumptions are forward looking and could be affected by future economic and market conditions. |
| *How We Addressed the Matter in our audit* | We obtained an understanding, evaluated the design and tested the operating effectiveness of management controls over the Company's determination of accounts payable to selling shareholders, including controls over management's review of the significant assumptions used in the prospective financial information.<br>To test the accounts payable to selling shareholders, our audit procedures included, among others, involving our valuation specialists to assist in evaluating the methodologies and key assumptions, including the estimated future revenue, growth rate and the discount rate used to prepare the projected financial information. We independently tested the interest expenses recognized during the year based on the terms and conditions of the agreements. We also performed sensitivity analyses to evaluate the change in the liability amounts resulting from changes in those assumptions. We also compared those significant assumptions to market benchmarks and evaluated them against known general economic trends. We also evaluated the Company's disclosures in Note 17. |

To the Shareholders and the Board of Directors of

#### Arco Platform Limited

#### Opinion on Internal Control over Financial Reporting
We have audited Arco Platform Limited and subsidiaries' internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Arco Platform Limited (the Company and subsidiaries) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on the COSO criteria.

**We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's consolidated statements of financial position as of December 31, 2022 and 2021, and the related consolidated statements of income, comprehensive income, changes in equity and cash flows for each of the three years in the period ended December 31, 2022, and the related notes and our report dated March 30, 2023 expressed an unqualified opinion thereon.**

#### Basis for Opinion
The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

#### Definition and Limitations of Internal Control Over Financial Reporting
A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

#### Notes to the consolidated financial statements

#### Expressed in thousands of Brazilian reais, unless otherwise stated

#### 1&nbsp;&nbsp;&nbsp;&nbsp;Corporate information
Arco Platform Limited ("Arco") is a holding company incorporated under the laws of the Cayman Islands on April 12, 2018, 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 a corporate reorganization and initial public offering 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. OSC Investments Limited is the ultimate parent company of Arco.

Since 2015, the Company has been investing in technology and its printed methodology has evolved to an educational platform capable of delivering the entire K-12 curriculum content. The Company serves private schools in several Brazilian states and cities where it delivers its printed and digital content.

The Company offers a complete pedagogical methodology using technology features to deliver educational content to improve the learning process. The Company's activities comprise the editing, publishing, advertising and sale of educational content for private schools.

The Company has an asset-light, highly scalable business model that emphasizes operational efficiency and profitability. Arco operates through long-term service contracts with private schools. These contracts generally have terms of validity ranging from one to five years, pursuant to which educational content is provided in printed and digital format to private schools. The revenue is driven by the number of enrolled students at each school using the solutions and the agreed upon price per student per year, all in accordance with the terms and conditions set forth in each contract. As a result, the Company benefits from high visibility in its revenue and operating margin, which is calculated by dividing the operating profit by revenue over a given period.

These consolidated financial statements were approved for issue by the Board of Directors on March 30, 2023.

**1.2&nbsp;&nbsp;&nbsp;&nbsp;Significant events during the year**

**For the year ended December 31, 2022**

&nbsp;&nbsp;&nbsp;&nbsp;(a) **Internal restructurings** 

Corporate restructuring

During the year, the Company completed the following incorporations as part of its corporate reorganization:

● On May 1, 2022, the incorporation of P2D Educação Ltda. by Companhia Brasileira de Educação de Sistemas de Ensino S.A.

● On August 1, 2022, the incorporation of Quadrado Mágico Desenvolvimento e Licenciamento de Software S.A. (Eduqo) and Studos Software Ltda. by Atech Soluções Tecnológicas S.A.

● On October 1, 2022, the incorporation of Geekie Desenvolvimento de Software S.A. by Companhia Brasileira de Educação e Sistemas de Ensino S.A.

The incorporations were part of a tax planning strategy to enable the Company to obtain tax benefits from the amortization of fair value adjustments and goodwill resulting from business combinations.

All incorporated companies were wholly owned subsidiaries of Arco and the incorporated assets and liabilities of the respective companies were recorded at their carrying amounts.

[**Table of Contents**](#TOC)

Non-Binding Proposal

On November 30, 2022, the Company's board of directors received a preliminary non-binding proposal (the "Proposal") from General Atlantic L.P. ("GA") and Dragoneer Investment Group, LLC ("Dragoneer") to acquire all of the outstanding Class A common shares of the Company (the "Proposed Transaction") that are not held by GA, Dragoneer, Oto Brasil de Sá Cavalcante ("Oto") or Ari de Sá Cavalcante Neto ("Ari" and together with Oto, the "Founders"), or their respective affiliates.

Pursuant to the terms of the Proposal, the Founders have stated that they support the Proposed Transaction and will agree to roll over 100% of their Class A common shares and Class B common shares. Following the closing of the Proposed Transaction, the Founders will maintain the same economic and voting interests in the Company that they currently own. The purchase price proposed by General Atlantic and Dragoneer for each Class A common share is US$11.00 in cash, which represents a premium of approximately 22% over the closing price of US$9.04 per Class A common share on November 30, 2022.

In January 2023, the Company's Board of Directors formed a special committee to evaluate the Proposal, as described in Note 30. At this time, it is uncertain that any definitive offer will be made, that any definitive agreement relating to the Proposal or any potential alternative transaction will be executed, or that the Proposed Transaction or any other transaction will be approved or consummated.

Shares repurchases

During the year, the Company purchased an aggregate amount of 551,125 Class A common shares for a total of R$53.1 million (equivalent to US$10.2 million) as described in Note 19.

&nbsp;&nbsp;&nbsp;&nbsp;(b) **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.

Issuance of debentures

In August 2022, the Company issued non-convertible debentures through its subsidiary, Companhia Brasileira de Educação e Sistemas de Ensino S.A. ("CBE"), consisting of 1,200,000 debentures with a unitary value of R$1.00, in the total amount of R$1,200,000. The net proceeds of R$1,188,980 are intended to pay the debentures issued by CBE in August 2021, currently totaling R$1,000,000, to strengthen the Company's cash position, and to extend the Company's debt maturity profile. See Note 15 for further information. These transactions were accounted for as a debt extinguishment according to IFRS 9.

&nbsp;&nbsp;&nbsp;&nbsp;(c) **Acquisition of interests in other entities and business combinations** 

Acquisition of additional shares of Geekie

Pursuant to the investment and share purchase agreement (SPA) for the acquisition of Geekie in November 2020, on June 1, 2022, Arco acquired the shares issued to the beneficiaries through the stock option plan, paying the amount of R$75,578, corresponding to 12.56% of the total shares, following the conditions previously negotiated in the SPA. At the same date, Arco paid R$223,939 to acquire the outstanding non-controlling interest of 37.23%.

[**Table of Contents**](#TOC)

Inco Acquisition

On October 6, 2022, the Company announced that it entered into a definitive agreement (the "Purchase Agreement") to acquire the remaining 75.1% of the share capital of INCO Limited ("Isaac"), the provider of an all-in-one platform that offers a suite of financial and software products to K-12 schools. The purchase price for the transaction will be paid in the form of Arco's own shares. Prior to the transaction, Arco already held 24.9% of the issued and outstanding equity interests of Isaac. Thus, the transaction will be treated as a step acquisition according to IFRS 3.

This transaction was approved by the Brazilian Administrative Council for Economic Defense (CADE) on November 16, 2022, and the transaction closing occurred in January 2023. Despite the fact that the transaction was approved by the regulatory body (CADE) in 2022, the acquisition date, however, was determined based on the date when Arco fulfilled all the conditions set by the terms in the Equity Purchase Agreement (EPA). As of December 31, 2022 there were several conditions outstanding to consummate the operation. The final closing of the transaction was on January 2, 2023. Therefore, Isaac only became part of the Company in January, not being included in the consolidation as of December 31, 2022.

*Fair value of the identifiable assets and liabilities*

The Company is evaluating the fair value of identifiable assets and liabilities as of the acquisition date and 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 deadline defined by IFRS.

*Purchase consideration*

In consideration for the purchase of the transaction, the Company delivered shares of its common stock to the selling shareholders.

Isaac shareholders received approximately 10.4 million shares of the Company's stock, equivalent to approximately 15.8% of the issued shares and outstanding equity interest, immediately following the closing of the transaction.

Of the 10,436,201 shares delivered to Isaac shareholders, 1,047,142 are treasury shares of the Company, and 9,389,059 are newly issued shares. The transaction resulted in a dilution of approximately 14.2% for the current shareholders of Arco.

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.

The Company don't 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.

*Goodwill*

The goodwill on the acquisition is being evaluated by experts and it is expected to be deductible for tax purposes after the Company incorporates the acquiree and 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 paid is based on the Business Plan prepared for purposes of the acquisition, and the principal business assumptions used were considered by management as appropriate.

For impairment testing purposes, goodwill will be allocated to the appropriate operating segment in accordance with the activities performed by Isaac and is being evaluated by management for proper allocation to existing segments or to a new segment to be defined.

Transaction costs of R$13,159 were expensed and are included in general and administrative expenses as of December 31, 2022.

As of December 31, 2022, Arco owns 100% of Me Salva! shares.

&nbsp;&nbsp;&nbsp;&nbsp;(d) **Acquisition of intangible assets**

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

The purchase consideration consisted of: (i) R$5,507 paid in February 2022; and (ii) R$8,701 paid in May 2022.

The brands have a strong presence in the Southeast region of Brazil, especially in the state of São Paulo.

Arco expects to accelerate the growth of COC and Dom Bosco by updating their content and technology, improving distribution and customer service capabilities, as well as to cross-sell supplemental solutions within the COC and Dom Bosco partner school base.

&nbsp;&nbsp;&nbsp;&nbsp;(a) During the year, the entity was incorporated by Companhia Brasileira de Educação e Sistemas de Ensino S.A. as described in Note 1.2 (a).

&nbsp;&nbsp;&nbsp;&nbsp;(b) During the year, the entity was incorporated by Atech Soluções Tecnológicas S.A. as described in Note 1.2 (a).

Consolidation of a subsidiary begins when the Company obtains control over the subsidiary and ceases when the Company loses control of the subsidiary. Control is achieved when the Company is exposed to, or has rights, to variable returns from its involvement with the investee and has the ability to affect those returns through its power over the investee. Specifically, the Company controls an investee if, and only if, it has: (i) Power over the investee (i.e., existing rights that give it the current ability to direct the relevant activities of the investee), (ii) Exposure, or rights, to variable returns from its involvement with the investee, and (iii) The ability to use its power over the investee to affect its returns.

Generally, there is a presumption that a majority of voting rights results in control. To support this presumption and when the Company has less than a majority of the voting or similar rights of an investee, the Company considers all relevant facts and circumstances in assessing whether it has power over an investee, including: (i) The contractual arrangements with the other vote holders of the investee, (ii) Rights arising from other contractual arrangements, and (iii) The Company's voting rights and potential voting rights.

Assets, liabilities, income and expenses of a subsidiary acquired or disposed during the year are included in the consolidated financial statements from the date the Company gains control until the date the Company ceases control of the subsidiary.

Where necessary, adjustments are made to the financial statements of subsidiaries to bring their accounting policies in line with the Company's accounting policies. All intra-group assets and liabilities, equity, income, expenses and cash flows relating to transactions, and any unrealized income and expenses arising from intra-group transactions, are eliminated in full on consolidation.

[**Table of Contents**](#TOC)

A change in the ownership interest of a subsidiary, without a loss of control, is accounted for as an equity transaction. If the Company loses control over a subsidiary, it derecognizes the related assets (including goodwill), liabilities, non-controlling interest and other components of equity, and any resulting gain or loss is recognized in profit or loss.

Non-controlling interests in the results and equity of subsidiaries are shown separately in the consolidated statements of income or loss and comprehensive income, changes in equity and financial position, respectively.

2.3&nbsp;&nbsp;&nbsp;&nbsp;Summary of significant accounting policies

This note provides a description of the significant accounting policies adopted in the preparation of these consolidated financial statements in addition to other policies that have been disclosed in other notes to these consolidated financial statements. These policies have been consistently applied to all periods presented, unless otherwise stated.

&nbsp;&nbsp;&nbsp;&nbsp;**a)** **Business combinations and goodwill** 

Business combinations are accounted for using the acquisition method. The cost of an acquisition is measured as the aggregate of the consideration transferred, which is measured at acquisition date fair value, and the amount of any non-controlling interests in the acquiree. For each business combination, the Company elects whether to measure the non-controlling interests in the acquiree at fair value or at the proportionate share of the acquiree's identifiable net assets. Acquisition-related costs are expensed as incurred and included in general and administrative expenses.

The Company determines that it has acquired a business when the acquired set of activities and assets include an input and a substantive process that together significantly contribute to the ability to create outputs. The acquired process is considered substantive if it is critical to the ability to continue producing outputs, and the inputs acquired include an organized workforce with the necessary skills, knowledge, or experience to perform that process or it significantly contributes to the ability to continue producing outputs and is considered unique or scarce or cannot be replaced without significant cost, effort, or delay in the ability to continue producing outputs.

When the Company acquires a business, it assesses the financial assets and liabilities assumed for appropriate classification and designation in accordance with the contractual terms, economic circumstances, and pertinent conditions as of the acquisition date.

Any contingent consideration to be transferred by the acquirer is recognized at fair value at the acquisition date. Contingent consideration classified as an asset or liability that is a financial instrument and within the scope of IFRS 9 Financial Instruments, is measured at fair value with the changes in fair value recognized in the statement of income or loss in accordance with IFRS 9. Other contingent consideration that is not within the scope of IFRS 9 is measured at fair value at each reporting date with changes in fair value recognized in profit or loss.

Goodwill is initially measured at cost (being the excess of the aggregate of the consideration transferred and the amount recognized for non-controlling interests and any previous interest held over the net identifiable assets acquired and liabilities assumed). If the fair value of the net assets acquired is in excess of the aggregate consideration transferred, the Company re-assesses whether it has correctly identified all the assets acquired and all the liabilities assumed and reviews the procedures used to measure the amounts to be recognized at the acquisition date. If the reassessment still results in an excess of the fair value of net assets acquired over the aggregate consideration transferred, then the gain is recognized in the statement of income or loss.

After initial recognition, goodwill is measured at cost less any accumulated impairment losses. For impairment testing, goodwill acquired in a business combination is, from the acquisition date, allocated to each CGU that is expected to benefit from the combination.

Where goodwill has been allocated to a segment and part of the operation within that segment is disposed of, the goodwill associated with the disposed operation is included in the carrying amount of the operation when determining the gain or loss on disposal. Goodwill disposed in these circumstances is measured based on the relative values of the disposed operation and the portion of the segment unit retained.

[**Table of Contents**](#TOC)

The current Brazilian tax law allows the deductibility of the acquisition date goodwill and fair value of net assets acquired when a corporate reorganization occurs after acquisition by the Company (i.e., when the Company merges or spins off the businesses acquired). Until such action occurs, the tax and accounting bases of the net assets acquired are the same as of the acquisition date and no deferred tax effects are recognized.

Certain acquired subsidiaries utilize the presumed profit regime as described in Note 24.a) to calculate income taxes. Under this regime, there is no difference between the carrying amount and related tax basis of assets and liabilities and therefore no deferred income taxes were recorded in these financial statements at acquisition date or any subsequent periods.

&nbsp;&nbsp;&nbsp;&nbsp;**b)** **Investment in associates and joint venture** 

An associate is an entity over which the Company has significant influence. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies.

A joint venture is a type of joint arrangement whereby the parties that have joint control of the arrangement have rights to the net assets of the joint venture. Joint control is the contractually agreed sharing of control of an arrangement, which exists only when decisions about the relevant activities require the unanimous consent of the parties sharing control.

The considerations made in determining significant influence or joint control are similar to those necessary to determine control over subsidiaries. The Company's investments in its associate and joint venture are accounted for using the equity method.

Under the equity method, the investment in an associate or a joint venture is initially recognized at cost. The carrying amount of the investment is adjusted to recognize changes in the Company's share of net assets of the associate or joint venture since the acquisition date. Goodwill relating to the associate or joint ventures is included in the carrying amount of the investment and is not tested for impairment separately.

The statement of income or loss reflects the Company's share of the results of operations of the associate or joint venture. In addition, when there has been a change recognized directly in the equity of the associate or joint venture, the Company recognizes its share of any changes, when applicable, in the statement of changes in equity.

The aggregate of the Company's share of profit or loss of an associate and a joint venture is shown on the face of the statement of income or loss outside operating profit and represents profit or loss after tax of the associate or joint venture.

The financial statements of the associate or joint venture are prepared for the same reporting period as the Company. When necessary, adjustments are made to bring the accounting policies in line with those of the Company.

After application of the equity method, the Company determines whether it is necessary to recognize an impairment loss on its investment in its associate or joint venture. At each reporting date, the Company determines whether there is objective evidence that the investment in the associate or joint venture is impaired. If there is such evidence, the Company calculates the amount of impairment as the difference between the recoverable amount of the associate or joint venture and its carrying value, and then recognizes the loss within share of profit (loss) of equity-accounted investees in the statement of income or loss.

&nbsp;&nbsp;&nbsp;&nbsp;**c)** **Current versus non-current classification** 

The Company presents assets and liabilities in the statement of financial position based on current/non-current classification. An asset is current when it is:

● Expected to be realized or intended to be sold or consumed in the normal operating cycle;

● Held primarily for the purpose of trading;

● Expected to be realized within twelve-months after the reporting period; or

● Cash or cash equivalent unless restricted from being exchanged or used to settle a liability for at least twelve-months after the reporting period.

[**Table of Contents**](#TOC)

All other assets are classified as non-current.

A liability is current when:

● It is expected to be settled in the normal operating cycle;

● It is held primarily for the purpose of trading;

● It is due to be settled within twelve-months after the reporting period; or

● There is no unconditional right to defer the settlement of the liability for at least twelve-months after the reporting period.

The terms of the liability that could, at the option of the counterparty, result in its settlement by the issue of equity instruments do not affect its classification.

The Company classifies all other liabilities as non-current.

Deferred tax assets and liabilities are classified as non-current assets and liabilities.

&nbsp;&nbsp;&nbsp;&nbsp;**d)** **Fair value measurement** 

The Company measures certain financial instruments such as, financial assets, financial investments, derivatives and financial liabilities at fair value at each balance sheet date.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement is based on the presumption that the transaction to sell the asset or transfer the liability takes place either.

● in the principal market for the asset or liability; or

● in the absence of a principal market, in the most advantageous market for the asset or liability.

The principal or the most advantageous market must be accessible by the Company.

The fair value of an asset or a liability is measured using the assumptions that market participants would use when pricing the asset or liability, assuming that market participants act in their economic best interest.

The Company uses valuation techniques that are appropriate in the circumstances and for which sufficient data are available to measure fair value, maximizing the use of relevant observable inputs and minimizing the use of unobservable inputs.

All assets and liabilities for which fair value is measured or disclosed in the financial statements are categorized within the fair value hierarchy, described as follows, based on the lowest level input that is significant to the fair value measurement as a whole:

● 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 in the financial statements 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.

At each reporting date, the Company analyzes the movements in the values of assets and liabilities which are required to be remeasured or re-assessed as per the Company's accounting policies. For this analysis, the Company verifies the major inputs applied in the latest valuation by agreeing the information in the valuation computation to contracts and other relevant documents.

[**Table of Contents**](#TOC)

The Company also compares the change in the fair value of each asset and liability with relevant external sources to determine whether the change is reasonable.

For the purpose of fair value disclosures, the Company has determined classes of assets and liabilities based on the nature, characteristics and risks of the asset or liability and the level of the fair value hierarchy, as explained above. See Note 26 for further information.

&nbsp;&nbsp;&nbsp;&nbsp;**e)** **Financial instruments – initial recognition and measurement** 

A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity.

*i) Financial assets*

#### Initial recognition and measurement
Financial assets are classified, at initial recognition, as subsequently measured at amortized cost, fair value through other comprehensive income (OCI), and fair value through profit or loss.

The classification of financial assets at initial recognition depends on the financial asset's contractual cash flow characteristics and the Company's business model for managing them. Except for trade receivables that do not contain a significant financing component or for which the Company has applied the practical expedient, the Company initially measures a financial asset at its fair value plus, in the case of a financial asset not at fair value through profit or loss, transaction costs. Trade receivables that do not contain a significant financing component or for which the Company has applied the practical expedient are measured at the transaction price under IFRS 15.

For a financial asset to be classified and measured at amortized cost or fair value through other comprehensive income (OCI), it should give rise to cash flows that are 'solely payments of principal and interest (SPPI)' on the principal amount outstanding. This assessment is referred to as the SPPI test and is performed at an instrument level. Financial assets with cash flows that are not SPPI are classified and measured at fair value through profit or loss, irrespective of the business model.

The Company's business model for managing financial assets refers to how it manages its financial assets to generate cash flows. The business model determines whether cash flows will result from collecting contractual cash flows, selling the financial assets, or both. Financial assets classified and measured at amortized cost are held within a business model with the objective to hold financial assets in order to collect contractual cash flows while financial assets classified and measured at fair value through OCI are held within a business model with the objective of both holding to collect contractual cash flows and selling.

#### Subsequent measurement
For purposes of subsequent measurement, financial assets are classified as: amortized cost or fair value through profit or loss. There are no financial assets designated as fair value through OCI.

*Financial assets at amortized cost*

Financial assets at amortized cost are subsequently measured using the effective interest (EIR) method and are subject to impairment. Gains and losses are recognized in profit or loss when the asset is derecognized, modified or impaired.

The Company's financial assets at amortized cost include trade receivables and certain financial investments.

*Financial assets at fair value through profit or loss*

Financial assets at fair value through profit or loss are carried in the statement of financial position at fair value with net changes in fair value recognized in the statement of profit or loss. This category includes derivative financial instruments.

[**Table of Contents**](#TOC)

A derivative embedded in a hybrid contract, with a financial liability or non-financial host, is separated from the host and accounted for as a separate derivative if: the economic characteristics and risks are not closely related to the host; a separate instrument with the same terms as the embedded derivative would meet the definition of a derivative; and the hybrid contract is not measured at fair value through profit or loss. Embedded derivatives are measured at fair value with changes in fair value recognized in profit or loss. Reassessment only occurs if there is either a change in the terms of the contract that significantly modifies the cash flows that would otherwise be required or a reclassification of a financial asset out of the fair value through profit or loss category.

*Derecognition*

A financial asset (or, where applicable, a part of a financial asset or part of a group of similar financial assets) is primarily derecognized (i.e., removed from the Company's consolidated statement of financial position) when:

● The rights to receive cash flows from the asset have expired; or

● The Company has transferred its rights to receive cash flows from the asset or has assumed an obligation to pay the received cash flows in full without material delay to a third party under a 'pass-through' arrangement-and either (a) the Company has transferred substantially all the risks and rewards of the asset, or (b) the Company has neither transferred nor retained substantially all the risks and rewards of the asset but has transferred control of the asset.

When the Company has transferred its rights to receive cash flows from an asset or has entered a pass-through arrangement, it evaluates if, and to what extent, it has retained the risks and rewards of ownership. When it has neither transferred nor retained substantially all the risks and rewards of the asset, nor transferred control of the asset, the Company continues to recognize the transferred asset to the extent of its continuing involvement. In that case, the Company also recognizes an associated liability. The transferred asset and the associated liability are measured on a basis that reflects the rights and obligations that the Company has retained.

Continuing involvement that takes the form of a guarantee over the transferred asset is measured at the lower of the original carrying amount of the asset and the maximum amount of consideration that the Company could be required to repay.

*Impairment*

Further disclosures relating to impairment of financial assets are also provided in the following notes:

● Disclosures for significant assumptions - Note 3

● Trade receivables, including contract assets - Note 7

The Company recognizes an allowance for expected credit losses (ECLs) for all debt instruments not held at fair value through profit or loss. ECLs are based on the difference between the contractual cash flows due in accordance with the contract and all the cash flows that the Company expects to receive, discounted at an approximation of the original effective interest rate. The expected cash flows will include cash flows from the sale of collateral held or other credit enhancements that are integral to the contractual terms.

For trade receivables, the Company applies a simplified approach in calculating ECLs. Therefore, the Company does not track changes in credit risk, but instead recognizes a loss allowance based on lifetime ECLs at each reporting date. The Company has established a provision matrix that is based on its historical credit loss experience, adjusted for forward-looking factors specific to the debtors and the economic environment.

[**Table of Contents**](#TOC)

The Company considers a financial asset in default when contractual payments are 360 days past due. Management considers this period of maturity to be adequate considering the Company's business model and the historical customer's payment since the contracts are signed annually and during this period the Company can negotiate the payment of the security reducing the credit risk. However, in certain cases, the Company may also consider a financial asset to be in default when internal or external information indicates that the Company is unlikely to receive the outstanding contractual amounts in full before considering any credit enhancements held by the Company. A financial asset is written off when there is no reasonable expectation of recovering the contractual cash flows.

#### ii) Financial liabilities

#### Initial recognition and measurement
Financial liabilities are classified, at initial recognition, as financial liabilities at fair value through profit or loss, loans and financing, payables, or as derivative financial instruments, as appropriate.

All financial liabilities are recognized initially at fair value and, in the case of loans and financing and payables, net of directly attributable transaction costs.

The Company's financial liabilities include trade payables, loans and financing, derivative financial instruments from acquisition of interests and accounts payable to selling shareholders.

#### Subsequent measurement
For purposes of subsequent measurement, financial liabilities are classified in two categories:

● Financial liabilities at fair value through profit or *loss* 

● Financial liabilities at amortized cost (loans and financing)

*Financial liabilities at fair value through profit or loss*

Financial liabilities at fair value through profit or loss include financial liabilities held for trading and financial liabilities designated upon initial recognition as at fair value through profit or loss.

Financial liabilities are classified as held for trading if they are incurred for the purpose of repurchasing in the near term. This category also includes derivative financial instruments entered by the Company that are not designated as hedging instruments in hedge relationships as defined by IFRS 9. Separated embedded derivatives are also classified as held for trading unless they are designated as effective hedging instruments.

Gains or losses on liabilities held for trading are recognized in the statement of income or loss.

Financial liabilities designated upon initial recognition at fair value through profit or loss are designated at the initial date of recognition, and only if the criteria in IFRS 9 are satisfied.

*Financial liabilities at amortized cost (loans and financing)*

After initial recognition, interest-bearing loans and financing are subsequently measured at amortized cost using the effective interest rate (EIR) method. Gains and losses are recognized in profit or loss when the liabilities are derecognized as well as through the EIR amortization process.

Amortized cost is calculated by considering any discount or premium on acquisition and fees or costs that are an integral part of the EIR. The EIR amortization is included as finance costs in the statement of income or loss. This category generally applies to interest-bearing loans and financing at Note 15.

[**Table of Contents**](#TOC)

#### Derecognition
A financial liability is derecognized when the obligation under the liability is discharged or cancelled or expires. When an existing financial liability is replaced by another from the same lender on substantially different terms, or the terms of an existing liability are substantially modified, such an exchange or modification is treated as the derecognition of the original liability and the recognition of a new liability. The difference in the respective carrying amounts is recognized in the statement of income or loss.

#### iii) Offsetting of financial instruments
Financial assets and financial liabilities are offset, and the net amount is reported in the consolidated statement of financial position if there is a currently enforceable legal right to offset the recognized amounts and there is an intention to settle on a net basis, to realize the assets and settle the liabilities simultaneously.

&nbsp;&nbsp;&nbsp;&nbsp;**f)** **Derivative financial instruments** 

#### Initial recognition and subsequent measurement
The Company has derivative financial instruments such as put options from investments and forward currency swaps to protect its exposure to foreign currency risks. Such derivative financial instruments are initially recognized at fair value on the date on which a derivative contract is entered into and are subsequently remeasured at fair value. Derivatives are carried as financial assets when the fair value is positive and as financial liabilities when the fair value is negative.

Any gains or losses arising from changes in the fair value of derivatives are recorded directly to finance result in the statements of income or loss.

&nbsp;&nbsp;&nbsp;&nbsp;g) **Cash and cash equivalents** 

Cash and cash equivalents in the statement of financial position comprise cash in banks and on hand and short-term highly liquid financial investments with an original maturity of three months or less, that are readily convertible to a known amount of cash and subject to an insignificant risk of changes in value.

&nbsp;&nbsp;&nbsp;&nbsp;h) **Inventories** 

Inventories are measured at the lower of cost or net realizable value. The costs of inventories are based on the average cost method and include costs incurred on the purchase of inventories, editorial production costs and other costs incurred in bringing them to their current location and condition. Costs of purchased inventory are determined after deducting any discounts and recoverable taxes.

Educational content relates to costs incurred to prepare the educational content. These costs include incurred personnel costs and third parties' services for editing educational content and related activities (graphic design, editing, proofreading and layout, among others).

The inventory reserve for educational content is calculated based on their expected net realizable value. Inventory reserve corresponds to a reserve for inventory obsolescence and is recorded in cost of sales. It is estimated based on the amount of educational content from prior collections which are no longer used for sale and educational content which the Company expects will not be sold based on the actual sales. In determining the inventory reserve, the Company considers management's current assessment of the marketplace, industry trends and projected product demand as compared to the number of units currently in inventory.

&nbsp;&nbsp;&nbsp;&nbsp;**i)** **Property and equipment** 

Property and equipment are stated at cost, net of accumulated depreciation and accumulated impairment losses, if any.

Subsequent expenditure is capitalized only if it is probable that the future economic benefits associated with the expenditure will flow to the Company.

[**Table of Contents**](#TOC)

Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets, as follows:

---

| | |
|:---|:---|
| Machinery and equipment | 10% |
| Vehicles | 20% |
| Furniture and fixtures | 10% |
| IT equipment | 20% to 33% |
| Facilities | 10% |
| Leasehold improvements | 20% to 33% |

---

An item of property and equipment and any significant part initially recognized is derecognized upon disposal or when no future economic benefits are expected from its use or disposal. Any gain or loss arising on derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the statement of income or loss when the asset is derecognized.

The residual values, useful lives and methods of depreciation of property and equipment are reviewed at each financial year end and adjusted prospectively, if appropriate.

&nbsp;&nbsp;&nbsp;&nbsp;j) **Leases** 

The Company assesses at contract inception whether a contract is, or contains, a lease. That is, if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration.

Company as a lessee

The Company applies a single recognition and measurement approach for all leases, except for short-term leases and leases of low-value assets. The Company recognizes lease liabilities to make lease payments and right-of-use assets representing the right to use the underlying assets.

*Right-of-use assets*

The Company recognizes right-of-use assets at the commencement date of the lease (i.e., the date the underlying asset is available for use). Right-of-use assets are measured at cost, less any accumulated depreciation and impairment losses, and adjusted for any remeasurement of lease liabilities. The cost of right-of-use assets includes the amount of lease liabilities recognized, initial direct costs incurred, and lease payments made at or before the commencement date less any lease incentives received. Unless the Company is reasonably certain to obtain ownership of the leased asset at the end of the lease term, the recognized right-of-use assets are depreciated on a straight-line basis over the shorter of its estimated useful life and the lease term, as follows:

Buildings &nbsp;&nbsp;&nbsp;&nbsp; 1 to 4 years <br> Equipment 1 to 4 years

If ownership of the leased asset transfers to the Company at the end of the lease term or the cost reflects the exercise of a purchase option, depreciation is calculated using the estimated useful life of the asset. Right-of use assets are also subject to impairment.

*Lease liabilities*

At the commencement date of the lease, the Company recognizes lease liabilities measured at the present value of lease payments to be made over the lease term. The lease payments include fixed payments (including in-substance fixed payments) less any lease incentives receivable, variable lease payments that depend on an index or a rate, and amounts expected to be paid under residual value guarantees. The lease payments also include the exercise price of a purchase option reasonably certain to be exercised by the Company and payments of penalties for terminating a lease, if the lease term reflects the Company exercising the option to terminate. The variable lease payments that do not depend on an index or a rate are recognized as expense in the period on which the event or condition that triggers the payment occurs.

[**Table of Contents**](#TOC)

In calculating the present value of lease payments, the Company uses the incremental borrowing rate at the lease commencement date if the interest rate implicit in the lease is not readily determinable. After the commencement date, the amount of lease liabilities is increased to reflect the accretion of interest and reduced for the lease payments made. In addition, the carrying amount of lease liabilities is remeasured if there is a modification, a change in the lease term, a change in the in-substance fixed lease payments or a change in the assessment to purchase the underlying asset.

*Short-term leases and leases of low-value assets*

The Company applies the short-term lease recognition exemption to its short-term leases of properties (i.e., those leases that have a lease term of 12 months or less from the commencement date and do not contain a purchase option). It also applies the lease of low-value assets recognition exemption to leases of office equipment that are considered of low value. Lease payments on short-term leases and leases of low-value assets are recognized as expense on a straight-line basis over the lease term.

*Company as a lessor*

The Company does not enter into leasing agreements as a lessor.

&nbsp;&nbsp;&nbsp;&nbsp;k) **Intangible assets** 

Intangible assets acquired separately are measured on initial recognition at cost. The cost of intangible assets acquired in a business combination is their fair value at the date of acquisition. Following initial recognition, intangible assets are carried at cost less any accumulated amortization and accumulated impairment losses. Internally generated intangibles, excluding capitalized development costs, are not capitalized and the related expenditure is reflected in profit or loss in the period in which the expenditure is incurred.

The Company capitalizes the costs directly related with the development of the educational platforms used to deliver content. These costs are substantially comprised of technology related services and payroll expenses, recorded as internally developed software in the educational platform accounting ledger. Development expenditure is capitalized only if the expenditure can be measured reliably, the product or process is technically and commercially feasible, future economic benefits are probable, and the Company intends to and has sufficient resources to complete development and to use or sell the asset. Otherwise, it is recognized in the statement of income or loss as incurred. After initial recognition, development expenditure is measured at cost less accumulated amortization and any accumulated impairment losses.

Costs associated with maintaining internally developed software are recognized as an expense as incurred.

The useful lives of intangible assets are assessed as finite.

Intangible assets with finite lives are amortized over the useful economic life and assessed for impairment whenever there is an indication that the intangible asset may be impaired. The amortization period and the amortization method for an intangible asset with a finite useful life are reviewed at least at the end of each reporting period. Changes in the expected useful life or the expected pattern of consumption of future economic benefits embodied in the asset are considered to modify the amortization period or method, as appropriate, and are treated as changes in accounting estimates. The amortization expense on intangible assets with finite lives is recognized in the statement of income or loss in the expense category that is consistent with the function of the intangible assets.

An intangible asset is derecognized upon disposal (i.e., at the date the recipient obtains control) or when no future economic benefits are expected from its use or disposal. Any gain or loss arising upon derecognition of the asset (calculated as the difference between the net disposal proceeds and the carrying amount of the asset) is included in the statement of income or loss.

&nbsp;&nbsp;&nbsp;&nbsp;l) **Impairment of non-financial asset** 

Further disclosures relating to impairment of non-financial assets are also provided in the following notes:

● Disclosures for significant accounting judgments, estimates and assumptions - Note 3

● Property and equipment – Note 12

[**Table of Contents**](#TOC)

● Intangible assets – Note 14

● Goodwill – Note 14

The Company assesses at each reporting date whether there is an indication that an asset may be impaired. If any indication exists, or when annual impairment testing is required for goodwill and intangibles with indefinite lives, the Company estimates the asset's recoverable amount. The recoverable amount is the higher of an asset's or CGU's fair value less costs of disposal and its value in use. The recoverable amount is determined for an individual asset, unless the asset does not generate cash inflows that are largely independent of those from other assets or groups of assets. When the carrying amount of an asset or CGU exceeds its recoverable amount, the asset is considered impaired and is written down to its recoverable amount.

In assessing value in use, the estimated future cash flows are discounted to their present value using a discount rate, equivalent to the pre-tax discount rate, that reflects current market assessments of the time value of money and the risks specific to the asset. In determining fair value less costs of disposal, recent market transactions are considered. If no such transactions can be identified, an appropriate valuation model is used. These calculations are corroborated by valuation multiples, quoted share prices for publicly traded companies or other available fair value indicators.

The Company bases its impairment calculation on detailed budgets and forecast calculations, which are prepared separately for each of the Company's CGUs to which the individual assets are allocated. These budgets and forecast calculations cover a period of five years. A long-term growth rate is calculated and applied to project future cash flows after the fifth year.

Impairment losses of continuing operations are recognized in the statement of income or loss in expense categories consistent with the function of the impaired asset.

For assets excluding goodwill, an assessment is made at each reporting date to determine whether there is an indication that previously recognized impairment losses no longer exist or have decreased. If such indication exists, the Company estimates the asset's or CGU's recoverable amount. A previously recognized impairment loss is reversed only if there has been a change in the assumptions used to determine the asset's recoverable amount since the last impairment loss was recognized. The reversal is limited so that the carrying amount of the asset does not exceed its recoverable amount, nor exceeds the carrying amount that would have been determined, net of depreciation, had no impairment loss been recognized for the asset in prior years. Such reversal is recognized in the statement of income or loss.

Goodwill is tested for impairment annually and when circumstances indicate that the carrying value may be impaired. An operating segment is the lowest level within the Company at which the goodwill is monitored for internal management purposes and therefore impairment tests of goodwill have been carried out at each operating segment level. Impairment is determined for goodwill by assessing the recoverable amount of each operating segment to which the goodwill relates. When 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.

&nbsp;&nbsp;&nbsp;&nbsp;m) **Provisions** 

Provisions are recognized when the Company has a present obligation (legal or constructive) as a result of past event, it is probable that an outflow of resources embodying economic benefits will be required to settle the obligation and a reliable estimate can be made of the amount of the obligation. The expense relating to a provision is presented in the statement of income or loss net of any reimbursement, when applicable.

If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, when appropriate, the risks specific to the liability. When discounting is used, the increase in the provision due to the passage of time is recognized as a finance cost.

&nbsp;&nbsp;&nbsp;&nbsp;n) **Labor and social obligations** 

Labor and social obligations are expensed as the related service is provided. A liability is recognized for the amount expected to be paid if the Company has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee and the obligation can be estimated reliably.

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;o) **Share-based payments** 

Certain key executives of the Company receive remuneration in the form of share-based compensation, whereby the executives render services as consideration for equity instruments (equity-settled transactions).

*Equity-settled transactions*

The expenses of equity-settled transactions are determined by the fair value at the date when the grant is made using an appropriate valuation model. That expense is recognized in general and administrative expenses, together with a corresponding increase in equity (share-based compensation reserve), over the period in which the service and, where applicable, the performance conditions are fulfilled (the vesting period). The cumulative expense recognized for equity-settled transactions at each reporting date until the vesting date reflects the extent to which the vesting period has expired and the best estimate of the number of equity instruments that will ultimately vest. The expense or credit in the statement of income or loss for a period represents the movement in cumulative expense recognized as at the beginning and end of that period.

Service and non-market performance conditions are not taken into account when determining the grant date fair value of awards, but the likelihood of the conditions being met is assessed as part of the Company's best estimate of the number of equity instruments that will ultimately vest. Market performance conditions are reflected within the grant date fair value. Any other conditions attached to an award, but without an associated service requirement, are considered to be non-vesting conditions. Non-vesting conditions are reflected in the fair value of an award and lead to an immediate expensing of an award unless there are also service and/or performance conditions.

No expense is recognized for awards that do not ultimately vest because non-market performance and/or service conditions have not been met. Where awards include a market or non-vesting condition, the transactions are treated as vested irrespective of whether the market or non-vesting condition is satisfied, provided that all other performance and/or service conditions are satisfied.

When the terms of an equity-settled award are modified, the minimum expense recognized is the grant date fair value of the unmodified award, provided the original vesting terms of the award are met. An additional expense, measured as at the date of modification, is recognized for any modification that increases the total fair value of the share-based payment transaction, or is otherwise beneficial to the employee. Where an award is cancelled by the entity or by the counterparty, any remaining element of the fair value of the award is expensed immediately through profit or loss.

The dilutive effect of outstanding options is considered in the computation of diluted earnings per share (see Note 20).

*Cash-settled transactions*

A liability is recognized for the fair value of cash-settled transactions. The fair value is measured initially and at each reporting date up to and including the settlement date, with changes in fair value recognized in employee benefits expense. The fair value is expensed over the period until the vesting date with recognition of a corresponding liability. The fair value is determined using a Black & Scholes model. The approach used to account for vesting conditions when measuring equity-settled transactions also applies to cash-settled transactions.

&nbsp;&nbsp;&nbsp;&nbsp;p) **Revenue from contracts with customers** 

*Revenue from sale of education content*

The Company sells educational content to private schools, which is delivered through printed and digital formats. Revenue from contracts with customers is recognized when control of the goods or services are transferred to the customer at an amount that reflects the consideration to which the Company expects to be entitled, i.e., at the moment it delivers the content to private schools in printed and digital format when the Company fulfills its performance obligation, and the revenue from these contracts is recognized at a point of time. Each contract contemplates penalties ranging between 20% to 100% of the remaining total value of the contract in the event of termination. However, the content already delivered to the private schools is not returned to the Company unless the contractual return conditions are met.

[**Table of Contents**](#TOC)

The Company has concluded that it is the principal in its revenue arrangements because it typically controls the goods or services before transferring them to the customers.

Revenue is driven by the number of students enrolled in each school and is based on a value negotiated with each contract through the conditions contained in the terms of sales. The technology is provided solely in support of the best use of its content. Both printed and digital content are the same.

The Company provides printed content capable of delivering the entire K-12 curriculum. The Company also provides digital content for the purpose of supporting the printed content, and includes video lessons, online homework and assessments that are not customized and have no stand-alone value if used separately or outside of the main context. In this context, the digital content and related features are an evolution from a totally printed methodology to a broader approach and will continue to evolve and change in the coming years but are currently still deeply entwined with the printed content.

Pursuant to the terms of the contracts, each year by the end of November the schools are required to provide the Company with an estimate of the number of enrolled students that will access the content in the next school year (which typically starts in February of the following year), allowing the Company to start the delivery of its educational content. Since the contracts with the schools allows product returns or increase in the number of enrolled students up to a certain limit, the Company recognizes revenue for the amount that is expected to be received based on past experience, assuming that the other conditions for revenue recognition are met. A right of return asset (and corresponding adjustment to cost of sales) is also recognized for the right to recover the goods from the customer.

The asset is measured at the former carrying amount of the inventory, less any expected costs to recover the goods and any potential decreases in value. The Company updates the measurement of the asset for any revisions to the expected level of returns and any additional decreases in the value of the returned products.

*Revenue from services*

*The Company provides services related to school management for private schools and students, and technological solutions for communicating with students' parents and a learning platform for students and teachers, which are delivered through monthly software licenses. Revenue from contracts with customers is recognized when the control of services is transferred to the customer for an amount that reflects the consideration to which the Company expects to be entitled for the exchange of services, that is, when it releases the license to use services of software for private schools.*

*The Company generates subscription revenue from the sale of user licenses, in which customers can use the services of online school management software. The services are sold directly to schools that bundle the subscription with their own services provided to end customers. The Company fulfills its performance obligation, and the revenue from these services is recognized on a straight-line basis during the subscription period.*

*Subscription revenue is driven by the number of students enrolled in each customer and is based on a value negotiated with each subscriber through the conditions contained in the terms of use.*

*Interest income*

For all financial instruments measured at amortized cost, interest income is recorded using the effective interest rate (EIR) method. The EIR is the rate that exactly discounts the estimated future cash receipts over the expected life of the financial instrument or a shorter period, where appropriate, to the net carrying amount of the financial asset. Interest income includes also gain from financial investments classified as financial assets at fair value through profit or loss. Interest income is included in finance income in the statement of income or loss.

*Costs to obtain a contract*

The Company incurs costs to obtain each sales contract and recognizes as an asset the incremental costs of obtaining a contract with a customer if the entity expects to recover those costs. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained.

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;q) **Taxes** 

*Current income tax*

Current income tax assets and liabilities are measured at the amount expected to be recovered from or paid to the taxation authorities. The tax rates and tax laws used to compute the amount are those that are enacted or substantively enacted at the reporting date.

Management periodically evaluates positions taken in the tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate.

*Deferred income tax*

Deferred income tax is provided using the liability method on temporary differences between the tax bases of assets and liabilities and their carrying amounts for financial reporting purposes at the reporting date.

Deferred income tax liabilities are recognized for all taxable temporary differences, except:

● When the deferred tax liability arises from the initial recognition of goodwill or an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss;

● In respect of taxable temporary differences associated with investments in subsidiaries, associates and interests in joint venture, when the timing of the reversal of the temporary differences can be controlled and it is probable that the temporary differences will not reverse in the foreseeable future.

Deferred income tax assets are recognized for all deductible temporary differences, the carry forward of unused tax credits and any unused tax losses. Deferred tax assets are recognized to the extent that it is probable that taxable profit will be available against which the deductible temporary differences, and the carry forward of unused tax credits and unused tax losses can be utilized, except:

● When the deferred tax asset relating to the deductible temporary difference arises from the initial recognition of an asset or liability in a transaction that is not a business combination and, at the time of the transaction, affects neither the accounting profit nor taxable profit or loss;

● In respect of deductible temporary differences associated with investments in subsidiaries, associates and interests in joint venture, deferred tax assets are recognized only to the extent that it is probable that the temporary differences will reverse in the foreseeable future and taxable profit will be available against which the temporary differences can be utilized.

The current Brazilian legislation allows the amortization of goodwill in at least 5 years, for tax purposes, in cases of merger, spin-off or incorporation. Thus, it is possible to have a tax benefit from goodwill in the incorporation since it has been generated in the acquisition of interests from third parties.

The carrying amount of deferred income tax assets is reviewed at each reporting date and reduced to the extent that it is no longer probable that sufficient taxable profit will be available to allow all or part of the deferred tax asset to be utilized. Unrecognized deferred income tax assets are re-assessed at each reporting date and are recognized to the extent that it has become probable that future taxable profits will allow the deferred income tax asset to be recovered.

Deferred income tax assets and liabilities are measured at the tax rates that are expected to apply in the year when the asset is realized or the liability is settled, based on tax rates (and tax laws) that have been enacted or substantively enacted at the reporting date.

The Company offsets deferred income tax assets and liabilities if the deferred income tax assets and liabilities relate to income taxes levied by the same taxation authority on either the same taxable entity or different taxable entities which intend either to settle current tax liabilities and assets on a net basis, or to realize the assets and settle the liabilities simultaneously, in each future period in which significant amounts of deferred income tax liabilities or assets are expected to be settled or recovered.

[**Table of Contents**](#TOC)

*Sales tax* 

Expenses and assets are recognized net of the amount of sales tax, except:

● When the sales tax incurred on a purchase of assets or services is not recoverable from the taxation authority, in which case, the sales tax is recognized as part of the cost of acquisition of the asset or as part of the expense item, as applicable;

● When receivables and payables are stated with the amount of sales tax included.

The net amount of sales tax recoverable from, or payable to, the taxation authority is included as part of receivables or payables in the statement of financial position

&nbsp;&nbsp;&nbsp;&nbsp;**r)** **Treasury shares** 

Own equity instruments that are reacquired (treasury shares) are recognized at cost and deducted from equity. No gain or loss is recognized in profit or loss on the purchase, sale, issue or cancellation of the Company's own equity instruments.

&nbsp;&nbsp;&nbsp;&nbsp;**s)** **Foreign currencies** 

The consolidated financial statements are presented in Brazilian Reais, which is also the Company and its subsidiaries' functional currency. For each entity, the Company determines the functional currency and items included in the financial statements of each entity are measured using that functional currency.

*Transactions and balances*

Transactions in foreign currencies are initially recorded by the Company's entities at their respective functional currency spot rates at the date the transaction first qualifies for recognition. Monetary assets and liabilities denominated in foreign currencies are translated at the functional currency spot rates of exchange at the reporting date. Differences arising on settlement or translation of monetary items are recognized in profit or loss.

&nbsp;&nbsp;&nbsp;&nbsp;**(d)** **Information related to Covid-19 pandemic** 

The beginning of 2022 was characterized by a significant growth in COVID-19 cases, thus 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.

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.

Notwithstanding the above, despite the gradual release of the restrictions by the authorities, most of its workforce is working on site applying a hybrid model.

The Company continues putting in place to safeguard the health and safety of the Company's employees, customers, and suppliers, and direct and indirect interest principal investment 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 procedure.

As of December 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.

[**Table of Contents**](#TOC)

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.

● 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.

2.4&nbsp;&nbsp;&nbsp;&nbsp;Changes in accounting policies and disclosures

#### New and amended standards and interpretations
The Company applied for the first-time certain standards and amendments, which became effective for annual periods beginning on or after 1 January 2022 (unless otherwise stated). The Company has not early adopted any other standard, interpretation or amendment that has been issued but is not yet effective.

***Onerous Contracts – Costs of Fulfilling a Contract – Amendments to IAS 37***

An onerous contract is a contract under which the unavoidable of meeting the obligations under the contract costs (i.e., the costs that the Company cannot avoid because it has the contract) exceed the economic benefits expected to be received under it.

The amendments specify that when assessing whether a contract is onerous or loss-making, an entity needs to include costs that relate directly to a contract to provide goods or services including both incremental costs (e.g., the costs of direct labor and materials) and an allocation of costs directly related to contract activities (e.g., depreciation of equipment used to fulfil the contract and costs of contract management and supervision). General and administrative costs do not relate directly to a contract and are excluded unless they are explicitly chargeable to the counterparty under the contract.

These amendments had no impact on the consolidated financial statements of the Company. The Company intends to use the practical expedients in future periods if they become applicable.

***Reference to the Conceptual Framework – Amendments to IFRS 3***

The amendments replace a reference to a previous version of the IASB's Conceptual Framework with a reference to the current version issued in March 2018 without significantly changing its requirements.

The amendments add an exception to the recognition principle of IFRS 3 Business Combinations to avoid the issue of potential 'day 2' gains or losses arising for liabilities and contingent liabilities that would be within the scope of IAS 37 Provisions, Contingent Liabilities and Contingent Assets or IFRIC 21 Levies, if incurred separately. The exception requires entities to apply the criteria in IAS 37 or IFRIC 21, respectively, instead of the Conceptual Framework, to determine whether a present obligation exists at the acquisition date.

The amendments also add a new paragraph to IFRS 3 to clarify that contingent assets do not qualify for recognition at the acquisition date.

These amendments had no impact on the consolidated financial statements of the Company as there were no contingent assets, liabilities or contingent liabilities within the scope of these amendments that arose during the period.

[**Table of Contents**](#TOC)

***Property, Plant and Equipment: Proceeds before Intended Use – Amendments to IAS 16 Leases***

The amendment prohibits entities from deducting from the cost of an item of property, plant and equipment, any proceeds of the sale of items produced while bringing that asset to the location and condition necessary for it to be capable of operating in the manner intended by management. Instead, an entity recognizes the proceeds from selling such items, and the costs of producing those items, in profit or loss.

In accordance with the transitional provisions, the Company applies the amendments retrospectively only to items of PP&E made available for use on or after the beginning of the earliest period presented when the entity first applies the amendment (the date of initial application).

These amendments had no impact on the consolidated financial statements of the Company as there were no sales of such items produced by property and equipment made available for use on or after the beginning of the earliest period presented.

***IFRS 1 First-time Adoption of International Financial Reporting Standards – Subsidiary as a first-time adopter***

The amendment permits a subsidiary that elects to apply paragraph D16(a) of IFRS 1 to measure cumulative translation differences using the amounts reported in the parent's consolidated financial statements, based on the parent's date of transition to IFRS, if no adjustments were made for consolidation procedures and for the effects of the business combination in which the parent acquired the subsidiary. This amendment is also applied to an associate or joint venture that elects to apply paragraph D16(a) of IFRS 1.

These amendments had no impact on the consolidated financial statements of the Company as it is not a first-time adopter.

***IFRS 9 Financial Instruments – Fees in the '10 per cent' test for derecognition of financial liabilities***

The amendment clarifies the fees that an entity includes when assessing whether the terms of a new or modified financial liability are substantially different from the terms of the original financial liability. These fees include only those paid or received between the borrower and the lender, including fees paid or received by either the borrower or lender on the other's behalf. There is no similar amendment proposed for IAS 39 Financial Instruments: Recognition and Measurement.

In accordance with the transitional provisions, the Company applies the amendment to financial liabilities that are modified or exchanged on or after the beginning of the annual reporting period in which the entity first applies the amendment (the date of initial application). These amendments had no impact on the consolidated financial statements of the Company.

These amendments had no impact on the consolidated financial statements of the Company as it did not have assets in scope of IAS 41 as at the reporting date.

***Standards issued but not yet effective***

The new and amended standards and interpretations that are issued, but not yet effective, up to the date of issuance of the Company's financial statements are disclosed below. 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:

● Amendments to IAS 1: Classification of Liabilities as Current or Non-current

● Disclosure of Accounting Policies (Amendments to IAS 1 and IFRS Practice Statement 2)

● Definition of Accounting Estimates (Amendments to IAS 8)

● Deferred Tax related to Assets and Liabilities arising from a Single Transaction (Amendments to IAS 12)

[**Table of Contents**](#TOC)

#### 3&nbsp;&nbsp;&nbsp;&nbsp; Significant accounting judgements, estimates and assumptions
The preparation of the Company's consolidated financial statements requires management to make judgments, estimates and assumptions that affect the reported amounts of revenues, expenses, assets and liabilities, and the accompanying disclosures, and the disclosure of contingent liabilities. Uncertainty about these assumptions and estimates could result in outcomes that require a material adjustment to the carrying amount of assets or liabilities affected in future periods. Accounting estimates and judgments are continually evaluated and are based on historical experience and other factors, including expectations of future events that are believed to be reasonable under the circumstances. Revisions to estimates are recognized prospectively.

Other disclosures relating to the Company's exposure to risks and uncertainties includes:

● Capital management – Note 27

● Financial instruments risk management – Notes 26 and 27

● Sensitivity analyses disclosures – Note 27

#### Estimates and assumptions
The key assumptions about the future and other key sources of estimation uncertainty as of the reporting date that include a significant risk of a material adjustment to the carrying amounts of assets and liabilities within the next financial year, are described below. The Company based its assumptions and estimates on parameters available when the consolidated financial statements were prepared. Existing circumstances and assumptions about future developments, however, may change due to market changes or circumstances that arise and that are beyond the Company's control. Such changes are reflected in the assumptions where they occur.

*Impairment of non-financial assets*

Impairment exists when the carrying value of an asset or cash generating unit ("CGU") or group of CGU exceeds its recoverable amount, defined as the higher of its fair value less costs of disposal and its value in use. The fair value less costs of disposal calculation is based on data available from binding sales transactions, conducted at arm's length, for similar assets or observable market prices less incremental costs of disposing of the asset. The value in use calculation is based on a discounted cash flow model ("DCF" model). The cash flows are derived from the budget for the next five years and do not include restructuring activities to which the Company has not yet committed or significant future investments that will enhance the performance of the assets of the CGU being tested. The recoverable amount is sensitive to the discount rate used for the DCF model as well as to expected future cash-inflows and the growth rate used for extrapolation purposes. The Company determined that its operating segments are the cash generating units. These estimates are most relevant to goodwill that are recognized by the Company. The key assumptions used to determine the recoverable amount for the different operating segments, including a sensitivity analysis, are disclosed and further explained in Note 14.

*Inventory allowance*

The Company recognizes a provision for disposal of inventory considering content from previous collections not sold and a prospective model to estimate the forecast of obsolescence of products from current collections. The applied model considers the historical data of non-realization of products to obtain the expected loss percentages. Any significant changes between the observed losses compared to the historical loss pattern impact the expected loss percentages estimated by the Company. See Note 8 for further information.

*Provision for expected credit losses of trade receivables and contract assets*

The Company uses a provision matrix to calculate ECLs for trade receivables and contract assets. The provision rates are based on days past due for customer. The provision matrix is initially based on the Company's historical observed default rates. The Company calibrates the matrix to adjust the historical credit loss experience with forward-looking information.

[**Table of Contents**](#TOC)

The assessment of the correlation between historical observed default rates, forecast economic conditions and ECLs is a significant estimate. The amount of ECLs is sensitive to changes in circumstances and of forecast economic conditions. The Company's historical credit loss experience and forecast of economic conditions may also not be representative of customer's actual default in the future. The information about the ECLs on the Company's trade receivables and contract assets is disclosed in Note 7.

*Share-based payment*

Estimating fair value for share-based payment transactions requires determination of the most appropriate valuation model, which depends on the terms and conditions of the grant. This estimate also requires determination of the most appropriate inputs to the valuation model including the expected life of the share option or appreciation right, volatility and dividend yield and making assumptions about them. For the measurement of the fair value of equity-settled transactions, the Company uses the Black & Scholes model. The assumptions and models used for estimating fair value for share-based payment transactions are disclosed in Note 18. b).

*Taxes*

Deferred income tax assets are recognized for deductible temporary differences and unused tax credits from net operating losses carryforward to the extent that it is probable that taxable profit will be available against which the losses can be utilized. Significant management judgement is required to determine the amount of deferred income tax assets that can be recognized, based upon the likely timing and the level of future taxable profits, together with future tax planning strategies.

The Company has R$157,786 (2021: R$104,329) in deferred income tax on tax loss carryforwards. Additionally, there is R$10,355 (2021: R$12,902) of unrecognized tax loss carryforwards as of December 31, 2022 related to subsidiaries that have a history of losses. Such unused tax loss carryforwards do not expire and may not be used to offset taxable income of other subsidiaries of the Company. See Note 24 for further information.

*Fair value measurement of financial instruments*

When the fair values of financial assets and financial liabilities recorded in the statement of financial position cannot be measured based on quoted prices in active markets, their fair value is measured using valuation techniques including the DCF model. The inputs into these models are taken from observable markets where possible, but where this is not feasible, a degree of judgement is required to estimate fair values. Judgements include considerations of inputs such as liquidity risk, credit risk and volatility. Changes in assumptions relating to these factors could affect the reported fair value of financial instruments. See Note 26 for further disclosures.

Contingent consideration, resulting from business combinations, is valued at fair value as of the acquisition date as part of the business combination. When the contingent consideration meets the definition of a financial liability, it is subsequently remeasured at each reporting date. This determination of fair value is based on discounted cash flows. The key assumptions taken into consideration are the probability of meeting each performance target and the discount factor (see Notes 6 and 26 for additional information).

(a)&nbsp;&nbsp;&nbsp;&nbsp; Goodwill

The carrying amount of goodwill by operating segment was:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  |  | **2022** |  | **2021** |
| Core |  | 1,475,141  |  | 1,474,166  |
| Supplemental |  | 475,735  |  | 475,735  |
|  |  | **1,950,876**  |  | **1,949,901**  |

*Impairment test for goodwill*

The Company tests at least annually the recoverability of the carrying amount of each operating segment. The process of estimating these values involves the use of assumptions, judgments and estimates of future cash flows that represent the Company's best estimate.

[**Table of Contents**](#TOC)

Goodwill is monitored by management at the level of cash generating unit, which is the same of the two operating segments. The Core and Supplemental operating segments had an important cash flow improvement as they have increased their number of students and achieved greater scale that positively impact the gross margin.

The value-in-use calculation is based on cash flow projections and financial budgets approved by management for a period of five years. Cash flows beyond the five-year period were extrapolated using an estimated growth rate. The growth rate does not exceed the average long-term rate for the industry. The value-in-use of the Core operating segment calculated for 2022 was R$3,688,516 (R$3,695,227 in 2021), and the carrying amount was R$3,052,295. The value-in-use of the Supplemental operating segment for 2022 was R$1,491,994 (R$1,758,097 in 2021), and the carrying amount was R$880,409.

The value-in-use calculations were based on the discounted cash flow model and are based on the following assumptions for those segments:

---

| | | | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|:---|:---|
|  |  |  | **Budget period** | **Budget period** | **Growth rate beyond**  | **Growth rate beyond**  |  |  |
|  | **Gross margin** | **Gross margin** | **growth rate** | **growth rate** | **budget period** | **budget period** | **Discount rate** | **Discount rate** |
|  | **2022** | **2021** | **2022** | **2021** | **2022** | **2021** | **2022** | **2021** |
| Core | 78.0% | 79.7% | 10.3% | 13.8% | 3.0% | 3.3% | 13.2% | 11.7% |
| Supplemental | 80.9% | 86.5% | 18.0% | 16.4% | 3.0% | 3.3% | 14.5% | 12.9% |

---

*Significant estimate: impact of possible changes in key assumptions*

A decrease in management estimated gross margin used in the value-in-use calculation for the Core operating segment as of December 31, 2022, to 76.5%, would have not resulted in the recognition of an impairment of goodwill. Also, the Company performed the same analysis for the Supplemental operating segment and concluded that a decrease to 79.4% and concluded it would have not resulted in the recognition of an impairment of goodwill.

In addition, an increase of more than 150 basis points in management's estimated discount rate applied to the cash flow projections of the Core operating segment for the year ended December 31, 2022, would have resulted in the recognition of an impairment of goodwill.

Also, the Company performed the same sensitivity analysis for the Supplemental operating segment (16.0% instead of 14.5%) and concluded it would have not resulted in the recognition of an impairment of goodwill.

There was no goodwill impairment for the years ended December 31, 2022, 2021 and 2020.

(b)&nbsp;&nbsp;&nbsp;&nbsp; Other intangible assets

Intangible assets, other than goodwill, are valued separately for each acquisition and are amortized over their respective useful lives. The useful lives and methods of amortization of other intangibles are reviewed each financial year end and adjusted prospectively, if appropriate.

&nbsp;&nbsp;&nbsp;&nbsp;(a) This amount is related to issuance of debentures in August 2021 to pay the amount due on the COC and Dom Bosco acquisition maturing in a single installment on August 25, 2023. The debentures bear interest of 100% CDI + 1.7% per annum and are guaranteed by Arco Educação S.A. The amount was settled in August 2022 upon issuance of the 2 <sup>nd</sup> emission of debentures mentioned in item (c) below.

&nbsp;&nbsp;&nbsp;&nbsp;(b) 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 (See Note 16 for further information). The loan payments will be paid quarterly in 12 installments, until October 28, 2024. The decrease in the current balance is mainly related to: (i) payment of R$19,593 related to the four installments in February, May, August and November 2022; and (ii) exchange variation of R$4,206 recognized as financial income in statement of income or loss.

&nbsp;&nbsp;&nbsp;&nbsp;(c) The 2 <sup>nd</sup> emission of debentures bear interest of 100% CDI + 2.3% pa, which will accrue and will also be payable every six months , with the first payment on February 3, 2023 and the last payment on August 3, 2027. The amount will be settled in 3 installments on August of each year from 2025 until 2027. The debentures are guaranteed by Arco Educação S.A.

&nbsp;&nbsp;&nbsp;&nbsp;(d) 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.

[**Table of Contents**](#TOC)

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 16 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 not similar. Therefore, the conversion option will be treated separately and classified as a derivative liability, see Note 16 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 initial transaction costs that are directly attributable to the issuance of the convertible notes were measured at fair value together with the financial liability on initial measurement. The transaction cost totaled R$13,032, including legal counsels and advisors.

*Covenants*

The debenture agreement provides for financial covenants, such as: financial covenants, including the achievement of a financial ratio obtained by dividing net debt (excluding the balance of convertible notes) by adjusted EBITDA less than 4x as of December 31, 2022; default on the financial obligations of the contract, bankruptcy or liquidation of the Company, limitation to carry out operations of acquisition, merger, sale or disposal of its assets, disclosure of financial statements.

These restrictive clauses are applicable as from the date the contract is entered into and becomes effective, to the extent that the events foreseen contractually occur.

As of December 31, 2022, the Company met all contractual commitments of its loans and financing operations. All financing arranged by Company is not subject to any financial covenants for the year ended December 31, 2021 and 2020.

**Geekie Plan**

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

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, Geekie 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 was classified as cash settled since all Geekie's employees have signed a mandatory contract to sell all the options 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 beneficiaries had the maximum period for exercising the options up to March 31, 2022, under penalty of forfeiture.

On June 1, 2022, the Company settled the stock option plan in the amount of R$75,578 in cash as described in Note 1.2. c).

The participant's right to effectively receive ownership of the restricted shares will be conditioned on 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, that is defined in each contract. The final vesting date of those contracts is demonstrated below. If a participant leaves the Company 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 the Company. The total amount due 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 bearer of Class A Common shares.

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

**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, vest over four years, on March 31 of each year.

In 2021, the Company transferred 9,841 investment shares under the Matching Program with an average price of R$192.2.

#### 20&nbsp;&nbsp;&nbsp;&nbsp;Earnings (loss) per share (EPS)

#### Basic
Basic earnings (loss) per share excludes the effects of dilution and is computed by dividing profit (loss) attributable to equity holders of the parent by the weighted average number of shares outstanding for the period.

#### Diluted
Diluted earnings (loss) 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 (loss) 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 15 and 16 (only if dilutive) and the denominator is increased to include the number of potentially dilutive Class A common shares assumed to be outstanding during the period.

In addition, the Company has restricted stock units (see Note 18) that are also considered in the calculation of diluted earnings per share if they have a dilutive effect.

The following table reflects the profit (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 of property and equipment and intangible assets. There were no inter-segment revenues in the years ended, 2021 and 2020.

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

There were no adjustments or eliminations in the profit or loss between segments. Segment assets and liabilities are measured in the same way as in the financial statements. These assets and liabilities are allocated based on the operations of the segment.

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

The Company's exposure to certain risks associated with the financial instruments is discussed in Note 27.

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.

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;(a) **Financial instruments at fair value through profit or loss** 

*Financial investments*

The Company designated part of its financial investments as financial assets at fair value through profit or loss, related to investment fund which investments were entered to achieve 124.1% of the CDI. The Company designated these investments at fair value through profit or loss, given the swaps exist solely for the counterparty to deliver a fixed return on CDI. See Note 6 for more details on the financial investments.

*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 and for the years ended December 31, 2022, 2021 and 2020 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 (gain of R$106,379, gain of R$861 and gain of R$562 for the years ended in December 31, 2022, 2021 and 2020, respectively).

&nbsp;&nbsp;&nbsp;&nbsp;(b) **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 are measured and recognized at fair value as follows:

---

| | | | |
|:---|:---|:---|:---|
|  | **Hierarchy** | **2022** | **2021** |
| **Financial assets** |  |  |  |
| Financial investments | Level 2 | 36103  |  |
| Derivative financial assets | Level 2 |  | 861  |
| Investments at fair value | Level 1 | 11214  | 9803  |
| **Financial liabilities** |  |  |  |
| Derivative financial liabilities - Swap | Level 2 | 8192  |  |
| Derivative financial liabilities - Put option | Level 3 | 105654  | 223561  |
| Accounts payable to selling shareholders | Level 3 | 687849  | 867264  |

---

As of December 31, 2022, and 2021, the Company assessed the fair values of its financial instruments. This assessment does not indicate fair values significantly different from the carrying amounts. 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.

[**Table of Contents**](#TOC)

There were no transfers between levels for recurring fair value measurements during the financial statements' periods presented herein.

*(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 level 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.

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 years ended December 31, 2022, 2021 and 2020:

---

| | | | |
|:---|:---|:---|:---|
| <br>**Recurring fair value measurements** | **Financial instruments**<br>**assets** | **Financial instruments**<br>**liabilities** | **Accounts payable to**<br>**selling shareholders** |

---

*(iv) Transfers between levels 2 and 3*

In the years ended December 31, 2022, 2021 and 2020, the Company did not transfer any financial instruments from level 2 into level 3.

[**Table of Contents**](#TOC)

*(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 hires specialists to measure fair value of certain financial assets and liabilities 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.

#### 27&nbsp;&nbsp;&nbsp;&nbsp;Risk
&nbsp;&nbsp;&nbsp;&nbsp;**(a)** **Financial risk management** 

The Company monitors market, credit, and operational risks in line with the objectives in capital management and counts with the support, monitoring, and oversight of the Board of Directors in decisions related to capital management and its alignment with the objectives and risks. The Company monitors the effectiveness of the Company's risk management.

The sensitivity analyses in the following sections relate to the position as of December 31, 2022.

*Capital management*

The Company's objectives when managing capital are to:

● maximize shareholder value;

● safeguard its ability to continue as a going concern, so that it can continue to provide returns for shareholders and benefits for other stakeholders; and

● maintain an optimal capital structure to reduce the cost of capital.

In order to maintain or alter the capital structure, the Company may adjust the amount of dividends paid to shareholders, return capital to shareholders, issue new shares or sell assets to reduce debt.

No changes were made in the objectives, policies, or processes for managing capital during the years ended December 31, 2022, 2021 and 2020.

*(i) Foreign exchange risk*

*Exposure*

The Company's exposure to foreign currency risk as of December 31, 2022 and 2021, was as follows:

---

| | | |
|:---|:---|:---|
|  | **2022** | **2021** |
| Cash and cash equivalents (Note 5) | 14143  | 154  |
| Loans and financing | (654514) | (654864) |

---

[**Table of Contents**](#TOC)

The Company does not operate outside Brazil and does not have exposure to foreign exchange risk on commercial transactions, i.e., revenues or expenses.

Sensitivity analysis

The sensitivity analysis as of December 31, 2022, consider three scenarios of U.S. dollar exchange rate variation, as follows:

● Base scenario - exchange rate as of December 31, 2022 of R$5.2171 per US$1.00;

● Scenario I - a 10% increase in the U.S. dollar exchange rate to R$5.7388 ; and

● Scenario II - a 10% decrease in the U.S. dollar exchange rate to R$4.6954 .

The table below set forth the sensitivity analysis as of December 31, 2022, for cash and cash equivalents and financial investments of US$2,711 thousand and for US$118,079 thousand of convertible notes, both denominated in U.S. dollar:

---

| | | | |
|:---|:---|:---|:---|
|  | **Base scenario** | **Scenario I** | **Scenario II** |
|  | Exchange rate: R$5.2171 | Exchange rate: R$5.7388 | Exchange rate: R$4.6954 |
| Finance income (costs) |  | R$63,016 | R$(63016) |

---

*(ii) Liquidity risk*

Management of the Company has responsibility for mitigating liquidity risk. In order to achieve its goals, management regularly reviews the risk and maintains appropriate reserves, including bank credit facilities with first tier financial institutions. Management also continuously monitors projected and actual cash flows and the combination of the maturity profiles of the financial assets and liabilities.

The main requirements for financial resources used by the Company arise from the need to make payments for printing educational content, freight expenses, operating expenses, labor and social obligations, acquisition of interest in other entities and other operating disbursements.

The table below summarizes the maturity profile of the Company's financial liabilities based on contractual undiscounted amounts:

---

| | | |
|:---|:---|:---|
| <br>**December 31, 2022** | **Less than**<br>**3 months** | <br>**Total** |
| Trade payables | 182748  | 182748  |
| Lease liabilities | 9080  | 76905  |
| Loans and financing | 88144  | 1936830  |
| Derivative financial liabilities | 838 | 113847  |
| Accounts payable to selling shareholders | 447492  | 1391203  |
|  | **728302**  | **3701532**  |

---

*(iii) Financial counterparty risk*

This risk arises from the possibility that the Company may incur losses due to the default of its counterparties. To mitigate these risks, the Company adopts as practice the analysis of the financial and equity situation of its counterparties.

Counterparty credit limits, which take published credit ratings and other factors into account, are set to cover the Company's total aggregate exposure to a single financial institution. Exposures and limits applicable to each financial institution are approved by our treasury within guidelines approved by the board and are reviewed on a regular basis.

[**Table of Contents**](#TOC)

*(iv) Interest rate risk*

Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Company's exposure to the risk of changes in market interest rates relates primarily to the Company's investments with floating interest rates. The Company is mainly exposed to fluctuations in CDI interest rates on financial investments, related parties, accounts payable to selling shareholders and loans and financing.

Sensitivity analysis

The Company has a significant portion of its financial investments indexed to the CDI variation. According to the reference rates obtained from the website of the Brazilian Stock Exchange – B3 S.A. - Brasil, Bolsa, Balcão ("B3") and projected for 12 months, as of December 31, 2022, the CDI rate was 13,65%.

As of December 31, 2022, the Company's management estimated two scenarios of the CDI rates at +10% and -10%, which were used as a basis for the possible and remote scenarios, respectively. The table below shows a summary of the scenarios estimated by Management and the effect on profit before income taxes:

---

| | | | |
|:---|:---|:---|:---|
| **December 31, 2022** | **Exposure** | **+10%**  | **-10%** |
| Cash equivalents | 190445  |  | (19045) |
| Financial investments | 422646  |  | (5769) |
| Accounts payable to selling shareholders | 703354  | 9601  |  |
| Related parties | 3956  | 54  |  |
| Loans and financing | 1551612  | 18035  |  |

---

The Company performed evaluation of their fair value at the end of each year in order to account for any changes to it, as disclosed in Note 26. These derivatives, which are not publicly traded, have specific conditions that do not enable the Company to present a sensitivity analysis in relation to specific interest rates or market indexes.

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

&nbsp;&nbsp;&nbsp;&nbsp;(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 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.

[**Table of Contents**](#TOC)

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 twelve-month period ended December 31, 2022, the Company recognized R$44,863 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.

#### 29&nbsp;&nbsp;&nbsp;&nbsp;Transactions not involving cash
During the years ended December 31, 2021, 2020 and 2019, the Company carried out the following non-cash transactions, which are not reflected in the statement of cash flows:

#### 30 &nbsp;&nbsp;&nbsp;&nbsp;Subsequent events
Acquisition of INCO

On January 3, 2023, the Company announced the completion of the previously announced acquisition of INCO. Under the terms of the Equity Purchase Agreement, Arco Platform Limited completed the acquisition of 75.1% of the share capital of Isaac through an exchange of Arco shares. Isaac's shareholders received 10,436,202 Arco Class A common shares of Arco, of which 1,047,142 shares were Arco treasury shares, and 9,389,060 shares were newly issued Arco shares. Prior to the Transaction, Arco held 24.9% of the share capital of Isaac. The final antitrust approval from Brazil's Administrative Council for Economic Defense – CADE was granted on November 16, 2022, with no restrictions.

Non-binding Proposal

On January 26, 2023, the Company announced the formation of a special committee composed of four independent and disinterested directors to evaluate and consider the Proposal as described in note 1.2.

The board of directors cautions the Company's shareholders and other potential investors considering investing or trading in the Company's securities that the Proposal is under evaluation by the special committee. However, no decisions have been made with respect to the Proposal and whether the Company will accept it. There can be no assurances that any definitive offer will be made, that any definitive agreement relating to the Proposal or any potential alternative transaction will be executed, or that the Proposed Transaction or any other transaction will be approved or consummated.

Federal Supreme Court ("STF") decision on tax matters res judicata

On February 8, 2023, the Plenary of the STF concluded the judgment of Questions 881 and 885, unanimously deciding that a final decision, called "transited in res judicata", on taxes paid continuously, automatically loses the effects of final and unappealable decisions in case of divergent and contrary pronouncement, when it occurs in concentrated control or under the general repercussion regime. The Company assessed the effects of this decision and did not identify any lawsuits impacted by this decision of the Supreme Court, as it does not have any judicial decisions that result in the suppression of its taxes, the matter of which has subsequently been judged in the opposite direction by the Supreme Court, in a concentrated control action or under the general repercussion regime. Additionally, the Company understands that the decision does not have direct or reflex application for the base date of December 31, 2022 and continues to monitor the evolution of the matter.
