2.3. Other relevant information:

Relationship with independent auditors

Pursuant to CVM Instruction No. 381/03, the Company reports that auditors Ernst & Young Auditores Independentes S.S., responsible for \auditing its financial statements, provided services unrelated to independent auditing in amounts exceeding 5% of their total fees, as described below:

Date of % of Service description Period Amount retainer auditing fees

Support to the forest operations department implementing S&OP (monthly harvest planning) and S&OE (weekly harvest planning) processes. We BRL 625 February/2020 9 months 12% tracked the process of continually improving forest thousand productivity analyses and actions proposed by Klabin for their evolution.

Version: 7 Reference Form- 2021- KLABIN S. A.

3.2. Non-accounting metrics:

a) Non-accounting metrics

The Company uses the non-accounting metric EBITDA (earnings before interest taxes, depreciation and amortization), as a means to provide a measure of its operational economic performance, which consists in operational income minus net financial income, equity income, depreciation, depletion and amortization and variation in the fair value of biological assets.

Generally accepted accounting practices in Brazil do not recognize EBITDA, and the metric does not represent the cash flow for the fiscal years presented, and must not be considered as a basis for dividends distribution, an alternative to net earnings, or a liquidity indicator.

The Company abides by the definitions for the disclosure of EBITDA as provided in CVM Instruction 527/12, and provides reconciled balances pursuant to the guidelines provided in said Instruction.

b) Reconciliation of amounts disclosed and amounts as in the audited financial statements

Consolidated 12/31/2020 12/31/2019 12/31/2018 (=) Net earnings (2,389,490) 714,618 186,818 (+) Income tax and social contribution (1,424,875) 149,908 (255,399) (+/-) Net financial income 7,029,131 1,661,848 3,052,186 (+) Amortization, depreciation and depletion on earnings 2,382,911 2,193,414 1,673,347 EBITDA 5,597,677 4,719,788 4,656,952

Adj. pursuant to CVM Inst 527/12 (+/-)Variation in the fair value of biological assets (658,389) (390,053) (628,367) (+/-) Equity income (33,123) (7,237) (5,964) (+/-) EBITDA from jointly held subsidiary - - 1,798 Adjusted EBITDA 4,906,165 4,322,498 4,024,419

(+/-) Ganho de ICMS na base de PIS/COFINS (iii) - (620,833) - (+/-) Ganho de compra vantajosa (iv) (206,061) - - LAJIDA (EBITDA) - ajustado (excluindo efeitos não recorrentes) 4,700,104 3,701,665 4,024,419

Adjustments for the purposes of the definition of adjusted EBITDA: (i) Change in the fair value of biological assets The change in the fair value of biological assets corresponds to gains or losses from the biological transformation of forest assets up until they can be used/sold during the formation cycle. Because this concerns an expected value of assets reflected in the Company’s income/loss, calculated based on assumptions included in the respective discounted cash flow with no cash effect upon booking, the fair-value change is excluded from adjusted EBITDA calculations.

(ii) Equity income and adjusted EBITDA from jointly held subsidiaries The equity income reflected in the Company’s income reflects the subsidiary’s profits/losses as recognized in its individual financial statements, calculated according to the Company’s

Page 13 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

percentage stake therein. In consolidated results, the equity income entry concerns jointly held subsidiaries. The profits/losses of jointly held subsidiaries is under the influence of items not included in EBITDA calculations, such as: net financial income, income tax and social contribution, amortization, depreciation and depletion, and change in the fair value of biological assets. For this reason, equity income is excluded from the calculations. Instead, the Company adds the adjusted EBITDA from jointly held subsidiaries, calculated in the same manner, and corresponding to the Company’s equity stake therein.

(iii) Exclusion of ICMS from the PIS/COFINS taxable base As discussed in the Material Fact announced to the market on August 22, 2019, there has been a final ruling granting the Company’s request to exclude the ICMS from the PIS and Cofins taxable base. This led to the addition of BRL 621 million to the Company’s income. This gain is characterized as non-recurring for its topical nature, and has been excluded from EBITDA calculations for comparative purposes and for the analysis of the Company’s nominal operations.

(iv) Gains from beneficial acquisition AS discussed in the Announcement to the Market released on March 29, 2020, the Company acquired the Brazilian packaging papers and corrugated cardboard business of International Paper do Brasil (“IP”). For this operation, the fiscal year’s income recognized a gain from beneficial acquisition in the amount of BRL 206 million during the measurement of the fair value of the assets and liabilities acquired. Said gain is characterized as non-recurring for its topical nature, and has been excluded from EBITDA calculations for comparative purposes and for analysis of the Company’s nominal operations.

c) Explain why the Company understands that this metric is more appropriate for the proper understanding of its financial standing and of income from its operations The Company’s management uses adjusted EBITDA as a performance metric and understands that disclosure thereof is more appropriate for the proper understanding of the Company’s financial standing, as it is a convenient measure of operational performance and enables comparisons with other companies in the same segment, even if they may calculate the metric differently. Adjusted EBITDA demonstrates the Company’s performance free from the influence of factors associated with the following, among others: (i) its capital structure, including interest expenses on its debt and the effects of foreign exchange rate variations on financial income; (ii) its tax structure, such as income tax and social contribution; (iii) the depreciation, depletion and amortization expense on its high balance of fixed and biological assets; (iv) changes in the fair value of biological assets that do not affect the Company’s cash position; and (v) exclusion of non-recurring items topically affecting income, so that the indicator can be compared evenly across different fiscal years.

Page 14 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

The Company’ understands that these characteristics make adjusted EBITDA a more convenient and appropriated performance metric, recognizing income arising exclusively from the performance of its activities.

4.1. Description of risk factors

Investment in securities issued by Klabin S.A. intrinsically involves exposure to certain risks. Before deciding to invest in any securities issued by the Company, potential investors must meticulously examine the information provided in the present Reference Form, the risks mentioned, the Company’s financial statements, and the respective audit notes.

The Company and its controlled entities are subject to several risks inherent to the segments in which they operate, which stem from possible changes in competitive, economic, political, social and weather-related conditions that may harm their business, operational results, and financial standing. Although the risks listed ahead are not the only ones that the Company and its controlled entities may face, they are, according to the best understanding of Management at the time of the publication of the present Reference Form, those with the highest degrees of relevance and exposure.

Notwithstanding, according to the layout of the present section "4. Risk factors", certain risk factors mentioned in one item may also apply to other items.

a) Concerning operations

Risks affecting the Company and the paper and packaging industry in general

Development of the Covid-19 pandemic declared by the World Health Organization (WHO), its perceived effects, and the manner in which the pandemic shall affect our business shall depend on future developments regarding contingency measures and external factors that may adversely affect the predictability and stability of our business, financial standing, operational results, cash flows, and delivery of expected results.

On December, 2019, the first case of the coronavirus disease (Covid-19) caused by the severe acute respiratory syndrome 2 (SARS-CoV-2) was reported in Wuhan, China. On March 11, 2020, the WHO declared a Covid-19 pandemic due to its rapid dissemination to other continents, including Europe, the Middle East and the Americas. The WHO also stated that its member countries should put in place effective measures to contain the spread and treat the infected population.

In response to the Covid-19 pandemic, government authorities implemented severe restrictive measures, including in areas where we operate. The measures were taken to protect the population, resulting in restrictions against the flow of people, quarantines and blockades, restrictions on travel and public transportation, lengthy shutdown of workplaces, supply chain interruptions, retail shutdowns, and generalized reduction of consumption by the population.

Our business and operations face the risk of material interruptions as a result of, without limitation, quarantines, cyber-attacks, employee absence due to illness or other factors, such as social distancing measures, travel restrictions, or other. If a significant share of our workforce is unable to work, for reasons including, without limitation, disease, travel restrictions, or pandemic-related government restrictions, our operations may be adversely affected. A lengthy period of remote working may also increase our operational risks, including, without limitation, cyber security risks that may jeopardize our ability to manage and operate the business.

Any disease outbreak that affects the population’s behavior or requires public policy placing limitation on circulation flows and/or social contact may adversely affect our business and the

Page 26 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

Brazilian economy. Disease outbreaks may also prevent workers from moving into our facilities (including due to restrictions or the large-scale contamination of our workforce), which would hamper the routine performance of our business. The total extent of the impact of the Covid-=19 pandemic on our business and operational results depends on future developments, including, without limitation, the duration and scope of the pandemic, which are uncertain and unpredictable, particularly in Brazil. These factors include the impact thereof on the capital and financial markets, any new information that may emerge on the severity of the virus, its spread to other regions, and the measures taken to contain it, including the effectiveness of any vaccine, among other factors.

We cannot guarantee that no more regional and/or global outbreaks shall take place, nor that there shall be no more Covid-19 waves. In the presence of any of the foregoing, we cannot guarantee the ability to take the measures needed to prevent negative impact on our business of a similar or even greater magnitude than that of the Covid-19 pandemic.

Finally, the impact of the Covid-19 pandemic may also trigger or aggravate other risks discussed in this section.

The Company may be unable to fully carry out its business strategy and maintain stable operational results and growth rates.

The Company’s ability to implement a business strategy and maintain stable operational results and growth rate depends on several factors, including the ability to:

 keep existing customers and attract new ones;

 establish and maintain partnerships;

 hire and retain skilled workers; and

 increase its ability to operate in existing markets and expand into new ones.

The Company’s loss, even if temporary, of any of the above, be it due to competitive difficulties or cost-related factors, and its potential inability to balance risks, uncertainties and problems, may limit its ability to fully carry out its business strategy and affect its ability to effectively compete in the market, with negative impacts on its operational results.

Successful operations depend on the ability to maintain existing customers and obtain new ones. Any failure to maintain or obtain clients may adversely affect the Company’s business, financial standing and operational results.

As a global producer of paper past, paper packaging materials and pine and eucalyptus logs, the Company’s operational performance depends on its ability to identity. Attract and maintain customer in each of the regions where it operates. This, in turn, depends on (1) research and development to maintain the ability to innovate; (2) sales and marketing efforts to increase market share and expand into new markets; and (3) the quality and reliability of the products made to meet customers’ demand. The ability to carry out these activities requires time and planning, and involves expenses, and the inability to execute any one of them successfully, given the competitiveness of the pulp, paper and packaging industry, may affect the Company in a materially adverse manner.

Page 27 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

The loss of key members of Management or the inability to hire and retain skilled employees, or properly train our personnel may negatively affect the Company.

The Company’s ability to maintain its competitive position largely depends on the experience of key members of Management. The Company does not enter into employment agreements or do- not-compete agreements with any members at the managerial or tactical level. There can be no assurance that the Company will be able to maintain the current members of Management, and the loss of any member, or the inability to attract and maintain experienced executives may materially and negatively affect the Company’s business, financial standing and operational results.

Furthermore, as part of its expansion strategy, the Company hires, trains and retains new employees for its operations. The Company is subject to material competition in its efforts to hire such employees, and there can be no assurance that it will be able to attract and train skilled employees in sufficient numbers to meet existing and upcoming business demands. In addition, the Company may have trouble retaining employees if it is unable to maintain an attractive business culture and competitive compensation levels. The hiring, training and retention of skilled labor is believed to be a critical factor for long-term success and business growth, and dissatisfying or faulty implementation of its strategy may materially and negatively affect the Company’s business, operational results or financial standing.

The loss of any member of management, or the inability to attract and retain experienced executives may adversely affect the Company’s business, financial standing and operational results.

The Company’s business includes relevant operational risks that, upon materialization, may partly stop its activities and adversely impact its results and financial standing.

The Company’s operations are subject to the risks associated with the production, storage and disposal of chemical waste, pressure containers and dams, and may experience situations including explosions, fires, wear and tear over time and due to the exposure to weather and natural disasters, mechanical failure, insufficient time for unscheduled maintenance or repairs, freight interruptions, chemical leaks, and other environmental hazards. The occurrence of any of the foregoing may cause injury or death, severe damages to property, the destruction of machinery and equipment, and environmental damages, leading to partial or full interruption of commercial and/or industrial activities, as well as to liability including damages and indemnity owed to third parties, with a potentially significant effect on financial results.

Among the main operational risks, are included:

i. Pressure vessel equipment: The Company uses equipment that is fundamental to the production process and that contains fluids and is designed to safely withstand internal pressures other than atmospheric pressure, such as: recovery boilers, steam and tanks with chemical products. In the event of a rupture and / or explosion, it may generate interruptions in production and also result in bodily injury or death;

ii. Fire in the manufacturing area: The Company is subject to fires considering the business in which it operates and the products and equipment used in the production process. The occurrence of fire in any of the factories may interrupt production, causing an increase in the costs of the process, generating significant adverse effects on the Page 28 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

business;

iii. Explosion of chemical products: The risk of explosion is located in the Company's plants, mainly in the paper and cellulose units due to the large volume of chemical products used in production. The high amount of flammable products in plants can, if not properly handled, critically impact people and also the environment.

Wood shortages for the manufacturing process

Wood is the main input for the production of paper and cellulose, and any event that may affect the forest base may directly influence the production of paper and cellulose, and / or increase production costs. With the expansion of production forecasted by the Company in the coming years, the planning and acquisition of forest assets are essential to achieve Klabin's strategic objective. Deviations in this prognosis can bring losses and uncertainties to the business. Pests and diseases are also other drivers of loss of forest base, in addition to possible competition with other crops (soy, sugar cane and others) can also lead to a decrease in the processes of expansion of the forest base.

Expansion, investment and acquisition projects may require additional funding that may not be available, or may not offer good cost-benefit ratios.

Expansion projects are capital-intensive and require significant additional funding, which may be obtained by means of the issuance of shares, or debt, or through bank financing, including funding from development banks, multilateral institutions, and/or export credit agencies. We cannot guarantee the availability of additional funding and, even if available, access to additional funding on competitive terms. Lacking access to funding under competitive terms may restrict the future growth and development of the business, as well as any expansion or acquisition projects, which may adversely affect the Company’s business, financial standing and operational results.

Delays expanding existing plants or building new ones may affect costs and operational business performance.

As part of the Company’s strategy to increase its market share and improve its competitiveness through greater economies of scale, it may expand or upgrade its facilities. Plant expansion or construction involves countless risks, including those associated with engineering, construction, regulation, and others arising from material challenges that may delay or prevent a project’s proper functioning, or significantly increase the costs and investments involved. The ability to successfully complete any expansion or new construction project in time is also subject to financing risk and other risks, in particular:

 The Company may be unable to complete any expansion or construction project on schedule or on budget, or may be forced by market circumstances or other factors to delay construction start or extend the completion schedule of new projects or expansions;

 New or modified facilities may not operate at predicted capacity, or may lead to higher than expected operational costs

 The Company may be unable to sell its additional output at attractive prices; and

 The Company may lack the resources or may be unable to secure financing to implement Page 29 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

growth plans.

The materialization of these or other risks may adversely affect the Company’s business, financial standing and operating results.

Indebtedness may negatively affect the Company’s financial health and operational flexibility.

The Company has taken on significant debt (from short- and long-term loans and debentures, aside from other interest-bearing liabilities, or any other liabilities). At yearend 2020, gross debt was BRL 26.7 billion, and we may incur significant additional debt, including: (i) through investment in expansion projects, (ii) in connection with discussions underway with financial institutions with which we are actively involved (consisting mainly in debt-management exercise) or (iii) otherwise. The Company’s debt and other financial obligations increase the potential for us to be unable to generate sufficient cash to make principal, interest and other debt payments as they come due. Debt may also have other significant consequences, such as:

 increasing the Company’s vulnerability to generally adverse economic, competitive and industrial conditions;

 limiting the Company’s ability to secure additional funding under satisfactory terms in the future for its working capital, investments, debt service, service needs, acquisitions, general corporate purposes, and/or other purposes;

 requiring the Company to allocate a significant portion of its operational cash flow to debt service, thereby reducing the funds available for operations, capital expenditures, and any future business opportunities;

 exposing the Company to a risk of higher interest rates, as a portion of the loans and financings are taken at floating interest rates;

 exposing the Company to the risk of accelerating outstanding debt, should we default on the terms of the contracts underlying our debt;

 limiting the Company’s ability to carry out strategic acquisitions, or forcing it to undertake non-strategic divestments;

 limiting the planning flexibility or ability to react to changes in the businesses and industries in which the Company operates;

 limiting the Company’s ability to adapt to evolving market conditions and to react to competitive pressures and adverse regulatory changes;

 limiting the ability to refinance debt or increasing the cost thereof;

 limiting the ability to carry out marketing and risk-coverage operations, reducing the number of counterparties with which such operations may be conducted, as well as the volume thereof, and

 placing the Company at a competitive disadvantage relative to competitors facing lower debt and other obligations, or better access to funding.

Page 30 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

Several other risks may have materially adverse effects on operational and financial results.

Operations are subject to several other risks affecting forests and manufacturing processes, including fires, climate change, disease, strikes, port stoppages, freight stoppages, electric failure, and industrial explosions, any of which may materially and adversely affect operational and financial results.

Failures affecting the Information Technology systems of the Company or its suppliers, including as concerns information security, may compromise operations.

The Company and its suppliers depend on IT systems to serve customers, perform cost analyses and set appropriate prices. IT system problems, security failures, or inadequate maintenance and updates may interrupt the operations of the Company or its suppliers, cause the Company to lose customers, contribute to disputes with customers, lead to breach of applicable regulations, increase administrative expenses, compromise the security of internal or customer data, or cause other adverse consequences. Insofar as technology controls, policies, procedures and safeguards may be insufficient, these and other significant changes in IT systems may adversely affect the Company’s business, financial standing and operating results.

IT systems are used at the administrative and operational business levels and at each operational stage. Insofar as technology controls, policies, procedures and safeguards may be insufficient, the regular operation of IT systems may be compromised by unpredictable circumstances, human and programming error, the infrastructure of the Company and/or of data processing service providers, and force majeure, including fire, explosion, disasters, and any other event or incident beyond the Company’s control.

Furthermore, the security of the IT systems or, as has been the case in the past, of the IT systems of IT service providers may be compromised, exploited or corrupted by experienced programmers or hackers, harming the IT operations of the Company or its IT server providers. In such cases, insofar as technology controls, policies, procedures and safeguards may be insufficient, such third parties may also capture or disclose confidential information of the Company and/or its customers. Any such event may adversely affect the Company’s operations, operating results, and/or reputation.

The Company’s insurance coverage may be insufficient to cover potential losses, or fail to cover certain damages, such as those caused by forest blights.

The Company aims to retain insurance coverage in line with the understanding of best international practices for similar operations and assets.

Factories are covered by fire and general operational liability insurance policies. Coverage also includes damages caused by natural events, such as unexpected events, floors, lightning strikes, and aircraft accidents. In addition, the Company’s insurance covers domestic and international merchandise shipments, including domestic and international general liability. Other risk factors, such as landslides, contamination and cave-ins are regularly analyzed for their technical probability of occurrence before any decision is made in connection with the purchase of insurance against them.

Indemnity from insurers may not be received in a timely manner and/or may be insufficient or Page 31 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

inadequate to cover all damages. In addition, the Company may be unable to maintain or renew its existing insurance policies at terms and prices it deems appropriate.

Furthermore, the Company may endure damages from loss events not covered by the insurance policies purchased, such as forest blights. In the event of loss events not covered by the insurance policies in force, the Company shall be entitled to no indemnity to support the resulting costs.

In any such case, the Company’s financial capacity may be adversely and significantly affected.

The Company may incur losses and spend time and money defending against pending litigation or administrative proceedings, each of which may materially and negatively affect it.

The Company is currently party to several legal and administrative proceedings associated with tax, administrative, environmental, civil and labor disputes, involving a total of approximately BRL 5 billion as at yearend 2020. Out of this, approximately BRL 52 million are provisioned for and deemed probable losses by the Company’s legal counsel. The Company’s financial standing may be partly affected in the event of unfavorable rulings in such court and administrative proceedings.

In addition, the Company is the beneficiary of tax benefits whose suspension, expiration, recall or non-renewal may adversely affect the Company’s income and/or net cash generation.

We are subject to labor risks, including increased labor costs and labor stoppages.

The Company incurs significant payroll expenses (payroll, cost of goods sold, sales expenses and general and administrative expenses), that were among our largest expenses for the fiscal years ending December 31, 2020, 2019, and 2018, in a total of BRL 2.2 billion, 1.7 billion, and BRL 1.6 billion, respectively. Our payroll expenses include total direct compensation paid to employees, severance expenses, and other benefits.

In addition, Klabin’s employees are unionized and covered by collective bargains, or similar arrangements, subject to periodical renegotiation. We have occasionally endured work stoppages. Furthermore, the Company may be unable to satisfactorily conclude labor negotiations, which may lead to a significant increase in labor costs, or to work stoppages or labor mobilizations that may disturb operations and affect returns. For example, in 2018, the Company faced a 21-day labor stoppage at its Puma plant, the economic effects of which have not been quantified.

Due to the competitiveness and to the influence of labor unions, the Company may face pressures to increase employee wages, as well the amount of benefits provided thereto. If the Company’s payroll expenses increase significantly, or if it faces labor mobilizations, its activities, financial standing and operational results may be adversely affected.

The Company is subject to strict environmental requirements and compliance with existing and future regulations may demand significant capital expenses and increase our operational costs.

The Company is subject to strict environmental laws and regulations in Brazil, at the federal, state and local levels. These regulations provide for complex rules governing environmental controls, including the disposal of hazardous materials and toxic waste. Amendments to environmental laws and regulations, or changes in the policy of enforcement of existing environmental laws and regulations may negatively affect it. The Company’s operations are supervised by government agencies that are responsible for enforcing pollution control, laws and regulations. These agencies may act against the Company if it fails to abide by the applicable environmental regulations, or in the event of hazardous accidents. As a consequence, the Company’s ability to operate may be suspended or negatively affected. Furthermore, failure to comply with such laws, regulations and licenses may lead to criminal charges against the Company and its employees, including liability for the related environmental reparation costs, which may be substantial and materially adverse to our financial standing and operational results.

In addition, environmental laws are becoming stricter in Brazil and internationally. As a result, the investments and expenses needed to comply with environmental laws may significantly increase in the future, which may materially and adversely affect the Company’s financial standing and operational results.

Failure to secure the required permits and licenses may negatively affect our operations.

The Company depends on the granting of licenses and permits from government agencies to perform some of its activities. This often requires certain conservation investments to offset probable impacts. In addition, the Company needs licenses to, among other activities, operate its plants and carry out activities that rely on chemicals. Licenses to operate require, among other duties, periodic reporting of compliance with emissions standards as set forth by environmental agencies. Failure to secure, renew, or comply with licenses to operate may delay the implementation of new activities, increase costs, lead to monetary penalties, or even suspend the activity in question, which may materially and adversely affect the Company.

Construction and maintenance costs in excess of those expected may negatively affect our financial standing and the results from our operations.

As part of its strategy to increase its share of the global market and improve competitiveness through economies of scale, Klabin has completed the Puma project, and is building the Puma II Project, and may continue to expand its existing production facilities or build one or more additional facilities. Expansion or construction of a production unit involves several risks. The ability to (i) complete projects on schedule; and (ii) obtain the expected efficiency from the machinery used to produce the Company’s products is subject, among other factors, to changes in the prices of labor and raw materials, changes in the economy at large, the Company’s ability to secure financing as needed, regulatory challenges, unsatisfactory performance on the part of contractors and subcontractors, and situations arising from unpredictable engineering issues.

These factors may significantly increase costs and affect the Company’s business, financial standing, and operational results.

The Company is subject to LIBOR-related risks.

On July 27, 2017, the head of the Financial Conduct Authority – FCA, announced an intent to Page 33 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

discontinue the use of the London Interbank Rate by the end of 2021. Because the statements of the head of the FCA are recent, no definitive information exists on the future use of the LIBOR or any other rate in particular that may replace it. Given this, the potential effect of any such event on the Company’s net financial results cannot yet be determined and, at the present time, it is impossible to predict the effect of the establishment of any alternative reference rates, or any other LIBOR changes that may be enacted in the United Kingdom or elsewhere.

Uncertainty surrounding these potential changes, alternative reference rates, or other reforms may materially affect the Company’s business, financial standing, and operating results.

b) Concerning its shareholder, directly or indirectly controlling shareholder, or controlling group

Some of our shareholders have the ability to determine the outcome of business actions or decisions, which may affect security holders.

Klabin Irmãos SA and Niblak Participações SA hold the majority of the voting capital of Klabin, and their votes, as well as those of their elected representatives on the Company's board of directors, are linked to decisions taken previously at a general meeting or meeting of the board of directors. management of Klabin Irmãos SA, pursuant to the shareholders' agreement of Klabin Irmãos SA As a result, these shareholders have the ability, in addition to electing the majority of the Company's Board of Directors, to determine decisions about the election of the Executive Board and future operations , including decisions regarding acquisitions and other business opportunities, the declaration of dividends that exceed the minimum requirements of the Bylaws and the Brazilian Corporate Law, and the issuance of additional shares and other securities. The decisions made by the controllers may be in conflict with the interests of the other shareholders of the Company.

Trades carried out by the shareholders may affect the market value of the Company’s shares

The Company’s shareholders may freely trade their shares as provided by the applicable law. If these shareholders trade material volumes of their shares, the shares’ market value may be adversely affected, in a manner beyond the Company’s ability to predict.

The Brazilian stock market’s volatility and lacking liquidity may substantially limit investors’ ability to sell their securities issued by the Company at a price and time of their choosing

Investment in securities traded in emerging markets, as is the case of Brazil, often involves a greater risk compared with more mature international securities markets. This is explained by the fact that the Brazilian market is significantly smaller, less liquid, more volatile and more concentrated. This volatility and lacking liquidity substantially limit the ability of the holders of the Company’s securities to sell them at a price and a time of their choosing, and may thereby negatively affect the market prices of securities issued by the Company.

The Company may require additional capital in the future, and raising additional capital by means of securities issues may dilute an investor’s share of total equity.

The Company may require additional funds in the future and may choose to raise such funds by means of public or private issues of securities. Any funds raised by means of the public

Page 34 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

placement of shares or share-convertible securities may affect share price and result in the dilution of an investor’s share of total equity.

The holders of the Company’s shares may not receive dividends, or may receive dividends below the minimum provided in the Bylaws.

Shareholders are entitled to a minimum 25% of the Company’s annual net earnings as calculated and adjusted pursuant to the Company’s Bylaws, to be paid as dividends. However, under certain circumstances, the Company may be unable to pay dividends, or may pay less than the required amount once such a measure has been approved at the Annual General Meeting. Such circumstances may include:

 Where net earnings are capitalized, used to offset losses, or retained as provided in the Corporations law;

 Where the Company’s financial standing is inconsistent with the payment of dividends; and/or

 Where the controlled entities’ cash flow and earnings, as well as distribution of such earnings as dividends, does not occur, causing the required dividends to exceed the realized portion of the fiscal year’s net earnings.

c) Concerning the Company’s subsidiaries and affiliates

The risks associated with subsidiaries and affiliates are the same as discussed in connection with the Company.

d) Concerning suppliers

The Company relies on the supply of inputs, raw materials and services to operate. Higher input prices may increase production cost and reduce the Company’s return

Klabin’s operational units receive supplies from several domestic and international suppliers and services providers. Many factors influence the Company’s competitive standing, including plant efficiency, operating ratios and the availability, quality and cost of certain inputs, such as chemicals, raw materials and services. The availability, quality or cost of such inputs may negatively affect the Company’s operational and financial performance.

Input prices may increase, which may lead to reduced returns for the Company, if it is unable to pass on any cost increases to customers. In addition, any changes in tax laws with higher tax rates may lead to higher input prices. The ability to pass on costs to customers through price increases or other adjustments is uncertain and depends on market conditions and may adversely affect the Company’s operating results and financial standing, where unavailable.

e) Concerning customers

Changes in the Company’s customers’ credit rating may negatively affect operations.

In the markets where the Company operates, it is customary, and sometimes required for competitive participation, for producers to make term sales. When term sales are made to customers, the company becomes exposed to credit risk. Therefore, changes in the Page 35 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

macroeconomic environment, on the conditions of the market in which the customers operate, and problems associated with customers’ management, may significantly affect their ability to pay the Company, affecting it directly and negatively.

The Company may also make advances to suppliers in connection with future expansion projects. Such advances are also subject to the same risks.

Any increase in the credit risk posed by customers may significantly affect the Company’s assets, cash flow and operational results.

The Company’s sales in the liquid packaging board segment are relatively concentrated.

The Company has relevant concentration of revenues in a single customer. In fiscal year 2020, sales to this customer answered for 12% of the Company’s net revenues.

The customer is under no contractual obligation to purchase any portion of the Company’s production. Therefore, should this customer for any reason cease to purchase the Company’s liquid packaging board, the Company’s operational results and financial standing may be negatively affected in a relevant manner.

f) Concerning the industries in which the issuer operates

The Company faces significant domestic and international competition from paper producers with substantial resources, which may adversely affect market share and profitability.

Most of the segments in which Klabin operates are highly competitive. In the packaging paper segment, the main competitors are WestRock, International Paper, Irani and Trombini. In the cardboard segment (except for liquid packaging board, the main domestic competitors are Suzano (who merged with another competitor, Fibria), Ibema and Papirus, with Klabin as the only domestic producer of liquid packaging board. In the corrugated cardboard boxes segment, the main domestic competitors are WestRock, Smurfit, Kappa, Irani and Trombini. In the bag and industrial bag paper segment, the main competitors are Trombini, Tedesco, Cocelpa, Conpel and Iguaçu. In the pulp segment, the main competitors are Suzano (which merged with Fibria), Cenibra, Lwarcel and Eldorado.

The Company’s main competitors in the international paper and cardboard market are: WestRock, Graphic Packaging and International Paper (North America); B. Korsnäs, Stora Enso and Metsä Board (Europe), and Cartulinas CMPC (Latin America). In the kraftliner market, its main international competitors are Smurfit Kappa, SCA and Portucel (Europe); Sappi (Africa), WestRock and International Paper (North America). In the industrial bags chain, the main competitor is Mondi. In the pulp segment (short- and long fiber, and fluff), the main competitors are Arauco and CMPC (Latin America), International Paper and Georgia Pacific (North America). In addition, the Company also faces competition in Brazil from many smaller manufacturers.

There can be no assurance that the Company will be able to maintain its competitive position. Should it be unable to maintain its status among the leaders of the above markets, its financial standing and operating results may be adversely affected.

Page 36 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

Paper and pulp prices are cyclical and subject to factors beyond the Company’s control. Changes in the prices of packaging paper and board may affect revenues and operational results.

The prices that the Company can charge for its pulp and packaging products depend on the going world prices for such products. The world prices of paper and pulp products have been historically cyclic, subject to significant fluctuations over short periods of time, depending on a series of factors beyond the Company’s control, including:

 World demand for pulp and packaging products;

 Customers’ current inventory levels;

 Global production capacity;

 The strategies embraced by the main pulp producers; and

 Availability of substitute products.

Price fluctuations do not take place year on year alone, but also within a certain year as a result of global and regional economic circumstances, capacity restrictions, plant openings and shutdowns, and the supply and demand of and for raw materials and finished products, among other factors.

Producers often grant discounts on listed prices to significant buyers. Market prices for packaging products may drop in the future, or there may be insufficient demand for the products that the Company makes, to enable economically operating production facilities.

There can be no assurance that product prices will stabilize of cease to drop in the future, or that the demand for the products that Klabin makes will not drop in the future. As a result, there can be no assurance that the Company will be able to operate its production facilities profitably in the future. The Company’s business, financial standing and operating results would be adversely and relevantly affected if procut prices dropped significantly.

Competition for land from producers or non-producers of eucalyptus and pine, or the loss of long-term land lease agreements may affect the Company’s expansion capacity and have material adverse effects.

The majority of the wood used in production processes is provided by own forest operations, which include planted forest areas in the vicinity of the production facilities. An increase in global demand for certain raw materials or grazelands may lead to increased competition for the land that the Company requires to maintain or expand its forest operations, which may in turn increase use-of-land costs.

The production of plants or crops other than eucalyptus and pine or the development of land for pasture may be economically superior to forest activities and, therefore, the increased price of land may inhibit expansion of the Company’s forest operations. For the same reason, the Company may face difficulties convincing third parties to lease land or maintain exiting long- term lease agreements to begin or expand eucalyptus cultivation. A reduction in the amount of land available or let in the regions where the Company operates may have materially adverse Page 37 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

effects on it.

The advent of new technologies, competing products and new consumer habits may lead to the substitution of the Company’s products for others of a lower price or with distinctive technology.

The advent of new technologies, as well as consumer habit changes, may cause the Company’s products to become obsolete, leading to the replacement of its products for others that are innovative, efficient, high-quality, or competitively priced. If the Company fails to anticipate the industry’s trends, or is unable to introduce or develop products and services at least at the same time as its competitors, the Company’s customers may cease to use its products, replacing them with competitors’. This may adversely affect the Company’s financial standing and operational results

Competitors’ investments in increased production capacity in the coming years may negatively affect the Company’s business.

The Company’s competitors recently announced several investments to expand production capacity. If some or all of these announcements result in increased competitor ´production capacity, there may be an imbalance of supply and demand that may lead to a decrease in product prices. Therefore, any significant price decreases may adversely affect the Company’s operating margins, profitability, and return on capital.

Furthermore, given an increase in market supply of products, Klabin may be forced to temporarily adjust its production volume to meet reduced demand, incurring the risk of operating with idle capacity and, therefore, with higher production costs.

g) Concerning regulation of the industries in which the issuer operates

The Company may incur higher environmental compliance costs.

The Company is subject to strict environmental laws and regulations at the federal, state and local levels. This set of rules contains complex environmental control standards, including standards governing the storage and disposal of hazardous materials and the emission of liquid, solid and gas pollutants. Noncompliance with these laws or regulations, or the occurrence of accidents affecting the environment may lead to administrative, civil and/or criminal penalties, with the imposition of fines, indemnities and/or financial disbursements on the Company, which may adversely affect its operational results and financial standing.

Note, also, that environmental law is becoming stricter in Brazil and internationally, and the investments and expenses required for compliance may increase significantly in the future, which may adversely affect the Company’s financial standing and operational results.

The Company is subject to anti-corruption, anti-bribery, anti- money laundering, and antitrust laws, regulations, and sanctions. Noncompliance with such laws or regulations may materially and adversely affect the Company’s reputation, operational results and financial standing.

Klabin is bound by applicable Brazilian anti-corruption, anti-bribery, anti-money laundering,

Page 38 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

environmental, and other laws, regulations and sanctions, and may be subject to laws and regulations in other jurisdictions. There can be no assurance that internal policies and procedures will be sufficient to prevent or detect inappropriate practices, fraud, or breaches of such laws and regulations by affiliates, employees, officers, executives, partners, agents and service providers, nor that any such will not act in a manner in breach of our policies and procedures. Any breach of such laws and regulations committed by the Company or any of its subsidiaries, employees, officers, executives, partners, agents and service providers may have a materially adverse effect on the Company’s business, reputation, operational results and financial standing.

h) concerning foreign countries where the issuer operates

The Company’s business and operational results may be partly affected by the performance of certain economies.

In the fiscal year ending December 31, 2020, exports answered for 41% of the period’s net revenues (40% of net revenues in FY 2019), and were shipped to 88 countries. If the economy is negatively affected in these countries, the Company’s operational results may be partly affected.

Furthermore, if such a situation occurs in a certain recipient of exports, the Company may redirect its sales elsewhere.

The Company’s exports are exposed to political and economic risks in foreign nations.

Exports expose the Company to risks not faced by companies whose operations are limited to Brazil or any single given country. For example, exports may be affected by restrictions and import tariffs, other trade protection measures, and import or export licensing requirements.

Future financial performance will depend significantly on the economic, political and social conditions of the main export markets. Other risks associated with international activities include:

 Reduced global demand for pulp, paper and packaging ´products, which may lead to reduced sales, operating results, and cash-flow generation;

 Changes in foreign exchange and inflation rates in the countries where the Company operates;

 Currency controls;

 Changes in the political or economic circumstances of a certain country or region, particularly developing markets;

 Adverse consequences of changes to regulatory requirements, including environmental standards and regulations;

 Difficulties and costs associated with compliance with and enforcement of a wide range of complex international laws, treaties and regulations;

 Adverse consequences of tax law changes; Page 39 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

 Higher distribution costs, marine freight volatility, or reduced availability for merchandise shipment;

 Strike or other events that may affect ports and transportation; and

 Trade blockades.

i) Concerning socio-environmental matters

Expropriation of land and occupation thereof by social movements may impact the use of the Company’s forest and industrial properties.

Several activist groups defend the redistribution of property by means of the trespass and occupation of privately held land, which could interrupt the Company’s operations. In addition, the Company’s lands may be subject to expropriation by the Brazilian Government. According to Brazilian laws, the Federal Government may expropriate land not in conformity with its “social purpose”, including rational and appropriate exploration, proper use of natural resources, preservation of the environment, compliance with labor laws, etc. If the Brazilian Government expropriates any of the Company’s properties, the Company’s operational results may be adversely affected insofar as compensation from the Government prose insufficient.

Operational events that may generate environmental impacts.

As indicated in item 'a', the Company's operations are subject to certain weather conditions, the effects of which, if materialized, may adversely impact the company's equity and financial position. Some of these items, although of operational origin, were classified in the Company's risk map as “socio-environmental”.

i. Breaking of any of the water dams: The Company has 3 water dams (2 located in Paraná and 1 in Santa Catarina), and the breach mainly of the dam located in Telêmaco Borba, in Harmonia lagoon could cause loss of life, property and environmental , in addition to adversely affecting the Company's business and reputation;

ii. Large-scale forest fire: Much of the wood used in the Company's production process is supplied by its own forestry operations, which include planting areas located close to its factories. The occurrence of large-scale fires may reduce the supply of wood to the Company or result in higher prices for the wood that is purchased. In addition to these points, we may have environmental impacts and loss of biodiversity, negatively affecting the Company's reputation and image;

iii. Contamination of the environment with chemicals: In its production process, the Company uses chemicals that can be harmful to the environment. In the event of contamination in the soil and / or rivers, springs or groundwater, expenses that are not expected to remedy the consequences may occur, in addition to negatively impacting the Company's image and reputation, due to losses of biodiversity.

Events associated with water scarcity

The Company’s production process is highly water-dependent. Droughts in some , resulting in water scarcity or rationing, particularly in the areas where the Company has manufacturing units, may adversely impact the Company’s business and results.

Climate-related events may adversely affect forest operations Page 40 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

Forest planting and wood harvesting activities may be influenced by weather-related issues that may adversely affect supply of the wood used in the Company’s production chain.

The weather-related events with the most risk exposure are as follows:

 El Niño: the high rainfall volume hampers withdrawal of wood from the field. To avoid this risk, the Company resorts to interim warehouses to which the wood harvested from the field is transferred during the dry season, providing a stockpile for periods of intense rainfall where withdrawing wood from the field is more difficult;

 La Niña: a dry period that poses a risk of loss of saplings (planting), which creates a future risk of dearth. This risk is mitigated with the use of hydrogel and irrigation systems;

 Fires: the areas face a risk of fires in the dry season. In connection with this, the Company employs surveillance teams with firefighting training. In parallel, the Company is examining implementation of long-range surveillance cameras, which would assist in monitoring; and

 Frost and wind damage: some forest regions are prone to microclimates that may damage crops. The Research and Development team has been carrying out genetic improvements to the quality of the material to be planted, in parallel with a study of each region’s soil.

Page 41 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

4.2 Description of the main market risks

The Company’s ordinary course of business is subject to market risks. Such risks are mainly associated with adverse foreign exchange and interest rate changes, the industry in general, activities and regulation of its area of operations, and the environmental licenses required to perform.

Currency instability may harm the Brazilian economy as well as the Company

Because of several pressures, the Brazilian currency has been enduring recurring oscillation relative to the US Dollar, the Euro, and other strong currencies over the past several years. These changes have affected and will continue to affect the Company’s financial standing and operational results. Over the past three years, the following exchange rate variations were observed (sell rate)

Currency 2020 2019 2018 2020/2019 2019/2018 Pair BRL/USD BRL/USD BRL/USD % % USD Avg. 5.39 3.95 3.66 31% 8% USD yearend 5.20 4.03 3.87 29% 4%

The Company’s export revenues are directly affected by exchange rate variations. The ’s depreciation relative to the US Dollar negatively affects the Company’s foreign currency-denominated debt, but has a positive impact on its export revenues (when denominated in Brazilian Reais in either case), thereby improving operational income. The opposite occurs when the Brazilian Real appreciates, reducing the principal and service of foreign currency- denominated debt, but negatively affecting export revenues and operating results (when denominated in Brazilian Reais, in each case).

In addition, certain operating costs and expenses are also affected by variations in the value of the Brazilian Real versus the US Dollar, including export insurance, freight cost, and the cost of certain chemicals used as raw materials. The Brazilian Real’s depreciation versus the US Dollar will increase these costs, whereas an appreciation of the Brazilian real will reduce them. Furthermore, we do not generally use derivatives to hedge against the exposure to this kind of foreign exchange rate risk.

Sensitivity analysis of the foreign exchange variation as shown below is calculated on the net foreign currency exposure (basically foreign currency-denominated loans and financings, accounts receivable from customers and accounts payable to suppliers). The scenarios disregard the effects of forecast export sales, which will to an extent offset any future foreign currency- related losses when realized.

It is important to emphasize that financing contracts are not set to mature in 2021 in any substantive manner. As such, foreign exchange variations will not affect the cash arising from this analysis. As the Company makes exports in foreign currency, it receives the foreign- currency funds needed to honor outlays from such financings, which protects its cash from such changes. Page 42 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

Furthermore, for fiscal year 2021, the Company embraced hedge accounting based on the cash flow from highly probable expected transactions, designating its revenues in US Dollars as a hedging instrument for its US Dollar-denominated debt. The practice is in line with Management’s risk management and strategy, pursuing equalization of the effects of foreign exchange rate variations on income statements insofar as they are effectively realized with the respective cash effects.

For the purposes of the sensitivity analysis, scenario I assumes the forward market rate as of the period when the financial statements as of December 31, 2020, were prepared; scenario II adjusts the rate up by 25%; and scenario III adjusts it up by 50%. Other variables remaining constant, the figure next illustrates the simulated effects of foreign currency variations on the future 12-month results:

At 12/31/2020 Scenario I Scenario II Scenario III US$ Rat e R$ gain (loss) Rat e R$ gain (loss) Rat e R$ gain (loss) A sset s Cash and cash equivalents 1 9 8,81 3 5 .2 6 1 2 ,9 2 3 6 .5 8 2 7 5 ,01 8 7 .89 5 3 5 ,4 6 3 Trade receiv ables, net of 1 08,3 84 5 .2 6 7 ,04 5 6 .5 8 1 4 9 ,9 2 8 7 .89 2 9 1 ,9 1 1 allowance for doubtful debts Other assets and liabilities (1 1 0,2 6 2 ) 5 .2 6 (7 ,1 6 7 ) 6 .5 8 (1 5 2 ,5 2 6 ) 7 .89 (2 9 6 ,9 6 9 ) Financing (3,660,696) 5 .2 6 (2 3 7 ,9 4 5 ) 6 .5 8 (5,063,840) 7 .89 (9,859,352)

Net effect on finance results (225,144) (4,791,420) (9,328,947) The effect of exchange rate variation from financial instruments designated in hedge accounting (loans and financings) applicable from 2021, is booked under shareholder’s equity, in the “Equity valuation adjustments’ line, net of applicable income taxes. The amounts accumulated in shareholders’ equity are booked in the income statement in the “Net revenues from sales” line, insofar as effective outlay associated with the designated loans and financings has taken place, with the generation of the respective revenue in US Dollars designated under the hedge to offset the US Dollar cash outlay, at which point the hedging instrument’s foreign exchange variation is recognized in income/loss.

Due to inflation pressures, the Brazilian Real depreciated periodically against the US Dollar and other foreign currencies. In the past, the Brazilian Government adopted several economic plans and used a series of exchange rate policies, including sudden devaluations, periodical mini- devaluations whose frequency ranged from daily to monthly, floating exchange rate systems, foreign exchange controls, and exchange rate markets. Occasionally, significant changes take place in the exchange rate between the Brazilian real and the US Dollar and other currencies. In addition, the has occasionally intervened to control unsteady foreign exchange rate moves.

One cannot tell whether or not the Central Bank of Brazil will continue to allow the Brazilian real to freely float. As a consequence, one cannot tell the impact that the Brazilian Government’s foreign exchange policies may have on the Company. There can be no assurance that, in the future, the Brazilian Government will refrain from imposing a range within which the real Brazilian Real-to-US Dollar exchange rate may vary, or from imposing fixed exchange rates, nor can one predict the impact such an event may have on the Company’s business, financial standing, or operating results.

Page 43 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

Some of the Company’s products are deemed to be commodities, that is, there is little control over their effective prices.

At the cellulose business unit, the Company’s prices are at a level with international market prices, which are set mainly by the supply-demand balance, by the global production capacity, and by world economy conditions. That is, by factors exogenous to the Company’s Management that may have significant impact on the Company’s results, affecting operating margins, profitability and return on invested capital. EBITDA, for example, tends to vary up or down approximately US$ 16 million per year, as the average price of cellulose varies 10 US Dollars per ton. In the paper and packaging segment, kraftliner is closest to a commodity, following listed prices in Europe as measured by the FOEX. In this case, the same 10 US Dollars variation in the average price of kraftliner will cause an impact of approximately US$ 4.5 million per year.

Production costs may be partly affected by commodity prices.

Some of the Company’s costs may be affected by exogenous factors such as the price of the commodities that form the production cost of the items that the Company markets. One example is fuel, where the Company is exposed to changes in international oil prices over which it has no control. Another example is surplus energy production, which the Company trades and uses to reduce the production cost of cellulose. The price of energy may be affected by market prices.

A downturn in domestic and world economic activity and consequent stagnation or deceleration of local or world GDP growth may reduce the demand for the Company’s products.

The Company’s operational results are affected by the level of economic activity in Brazil and worldwide. An economic downturn in Brazil and around the world typically results in reduced industrial output, which, by its turn, implies reduced consumption of the Company’s products. Should the Brazilian and world economy experience a downturn, the Company’s operational results may be adversely affected.

High interest rates or interest rates at persistently high levels may have adverse effects for the Brazilian economy and the Company.

The Company is exposed to interest rate risk, as the majority of its financial obligations is pegged to floating rates (long-term interest rate as defined by the Central Bank of Brazil and Interfinancial Rate). The Brazilian short-term interest rate, which derives from the short-term interest rate set by the Central Bank of Brazil, has been at high levels in recent years. The Funds rate is the basic rate payable to holders of certain securities issued by the Brazilian Government and traded on the Sistema Especial de Liquidação e Custódia (SELIC). The funds rate has been occasionally kept at levels deemed incompatible with sustained economic growth.

On December 31, 2020, 2019 and 2018, the SELIC rates were at 2%, 5.97% and 6.43% p.a., respectively.

Should the Federal Government increase the interest rates, including the long-term interest rate, or take other monetary policy steps leading to a significant increase in interest rates, the Company’s financial expense may significantly increase because of its indexation to the

Page 44 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

applicable rates, adversely affecting its economic and financial standing.

Financial investments and financings are pegged to the CDI (Interfinancial) post-fixed interest rate, with the exception of those pegged to the TJLP. For the purposes of the sensitivity analysis below, the Company assumes the rates in force on dates close to the submission of the financial statements as of December 31, 2020, using the same rates in Scenario I for the Selic, IPCA and CDI, due to the proximity of the dates.

The Brazilian Government has exerted and continues to exert significant influence on the local economy. This influence, as well as the Brazilian economic and political situation, may adversely affect the Company.

The Brazilian economy has been characterized by intervention from the Brazilian Government, which has frequently changed monetary, credit, and other policies to influence the domestic economy. The Brazilian Government’s actions to control inflation and affect other policies often involve wages and prices controls, devaluations of the Brazilian real, control on overseas funds transfers, fluctuations of the Central Bank of Brazil’s Funds Rate, among other measures. The Company has no control over the measures or policies that the Brazilian Government may adopt in the future, and no means to predict what they may be. The Company’s business, financial standing, operating results and prospects may be harmed by relevant changes in policies or standards involving or affecting factors such as:

 expansion or contraction of the global or Brazilian economy;

 currency controls and restrictions against foreign transfers;

 economic and social instability;

 political elections;

Page 45 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

 import and export controls;

 relevant foreign exchange changes;

 fiscal and tax regime changes;

 labor law changes;

 liquidity of the domestic financial and capital markets;

 interest rates;

 inflation;

 monetary policy;

 regulatory environment affecting the Company’s activities;

 fiscal policy; and

 other political, diplomatic, social and economic developments that may take place in or affect Brazil.

Uncertainty regarding the Brazilian Government’s adoption of changes to policies or standards affecting these or other factors in the future may contribute to the local economic uncertainty and to increasing the volatility of the Brazilian securities market and of the securities issued abroad by Brazilian companies. Such uncertainties and other future developments in the Brazilian economy may affect the Company.

Brazilian politics has historically affected the performance of the Brazilian economy, and previous political crises have affected the confidence of investors and the public at large, usually leading to deceleration of the economy and volatility of securities issued by Brazilian companies. Political crises have affected and continue to affect the confidence of investors and the public at large, leading to deceleration of the economy and volatility of securities issued by Brazilian companies.

New and amended Brazilian policy and regulations, be it in response to new demonstrations, as a result of the recent elections, or otherwise, may have materially adverse effects on the Company’s business, financial standing and operating results.

Furthermore, uncertainty regarding the incumbent administration’s future political power or will to implement additional and necessary policies or regulations affecting the factors above or others may also contribute to economic uncertainty and to the increase volatility of securities issued abroad by Brazilian companies.

Corruption scandals have adversely affected the Brazilian economy and the Company’s business, operating results and common share trading prices.

Brazilian markets have been more volatile due to uncertainty arising from the corruption scandals currently under Federal Prosecution investigation. These investigations affect the Brazilian economy and the political environment. Countless members of the administration and

Page 46 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

Congress, as well as ranking officials of large public- and private-sector companies have been sentenced for or are facing charges of corruption for allegedly corrupting government officials with bribes linked with contracts granted by the government to several companies in the infrastructure, oil & gas, and construction industries as well as other crimes over the years. Proceeds from these bribes financed political parties’ campaigns remained undeclared or undisclosed, and were misappropriated by recipients of funds in the bribery scheme. As a result, several ranking politicians, including members of Congress, and employees of some of the main state-owned and private-sector companies in Brazil stepped down or were arrested and sentenced, and several public officials (including ranking members of Congress) are under investigation of unethical and illegal behaviors identified during the Lava-Jato probe and other investigations.

The outcome of the investigations is uncertain, but they have already had adverse effect on the image and reputation of the companies involved and on the market’s overall perception of the Brazilian economy, political environment, and capital markets. The ongoing investigations have adversely affected, and continue to affect, the Company’s business, financial standing, operating results and common-share trading prices. One cannot tell whether or not such allegations will cause additional political and economic instability, or whether or not new allegations against government officials and other large companies will emerge.

Newspapers, social and online media, publications and reports allege that certain Brazilian industries and conglomerates were involved in the conducts addressed by some of these investigations. Insofar as such reports and publications, or additional developments of or allegations connected to them or to the investigations mentioned before concern the Company or any of its affiliates, executives, or officers, the Company’s public perception, reputation, and security trading prices may be materially and adversely affected.

The Brazilian Government’s initiatives to control inflation may significantly contribute to economic uncertainty in Brazil and reduce demand for the Company’s products.

The Brazilian Government’s inflation-control efforts have frequently included adoption of a restrictive monetary policy with high interest rates, thereby restricting credit availability and economic growth. Inflation, measure to combat it, and public speculation on potential additional actions have also contributed significantly to economic uncertainty in Brazil in the past, and to increased volatility in Brazilian securities markets.

Potential future steps on the part of the Brazilian Government, including interest rate cuts, intervention in the foreign exchange market, and steps to adjust of set the value of the Brazilian real, may lead to increased inflation. If Brazil experiences increased inflation in the future, the Brazilian Government may choose to raise official interest rates.

An interest rate increase may have an adverse effect on the Company’s activities and payment capacity for the following reasons: (i) periods of higher inflation may decelerate the Brazilian economic growth rate, which may reduce demand for the Company’s products in Brazil and reduced net sales revenues; (ii) the Company may be unable to adjust the prices it charges from its customers and obligors to offset the effects of inflation on its cost structure; (iii) rising inflation rates may lead to higher domestic interest rates, with direct impact on the Company’s cost of funding, as well as its financing cost, increasing the cost of servicing the Company’s

Page 47 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

BRL-denominated debt and thereby leading to lower net profits, and (iv) rising inflation rates and their effect on the domestic interest rate may reduce the Company’s liquidity in domestic capital and credit markets, directly affecting its ability to refinance its debt. Any decrease in net revenues or net earnings, and any deterioration of the Company’s economic and financial standing may affect its payment capacity.

Political, economic and social developments and perceived risks in other countries may harm the market price of Brazilian securities, including the market price of the Company’s securities.

The market for the securities issued by Brazilian companies is influenced by the economic and market conditions in Brazil and, in varying degrees, by market conditions elsewhere, including Latin America and other developing countries. Although economic circumstances are different in each country, investor reactions to events in one country may cause the capital markets of other countries to vary. Events or conditions in other countries, including developing counties, have occasionally and significantly affected the availability of credit in the Brazilian economy and led to sizeable funds flights and reductions in the amount of foreign currency invested in Brazil, as well as to limited access to capital markets, all of which may materially and adversely affect the Company’s ability to secure loans at an acceptable interest rate or to raise capital if and when needed. The volatility of the market prices for Brazilian securities has increased from time to time, and investor perceptions as to increased risk due to crises elsewhere may also lead to a reduction in the market price of notes. The recent investment and entry of speculative capital resulted in the devaluation of the real against the US dollar, affecting the Company's revenue.

Customer credit risk in connection with payment of the Company’s outstanding receivables

The Company’s customers may fail to honor their obligations, creating financial losses arising from the non-realization of the balance of sales made, due to financial hardship. The Company’s portfolio of customers is diversified across the domestic and international markets.

Credit quality as concerns the Company’s operational activities is managed based on specific customer acceptance standards, credit review, and establishment of exposure limits by customer, all of which are periodically revised to ascertain customers’ financial health and payment capacity. Overdue invoices are promptly monitored to pursue payment, and estimated losses from bad credits are recognized for items that may not see payment

The Company has since April 2017 maintained insurance against domestic and international market receivables for all of its business units, except wood customers of the forest unit, in addition to certain customers that fail to meet specific risk requirements, such as continuity and liquidity, which the insurance company analyzes for incorporation under the policy. The Policy currently in force expires in October 2021.

On December 31, 2020, the Company’s maximum exposure to credit risk from customer receivable was BRL 1.9 billion. The amount of bad credit losses relative to the total was BRL 76 million

A possible global economic downturn may negatively affect the demand for and price of cellulose, paper and packaging.

Demand for the Company’s products is directly connected with global economic conditions and the economic conditions of the markets in which its products are traded. Continued economic activity decline, be it domestic or international, may have a negative effect on the demand for

Page 48 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

and price of the Company’s products, with materially adverse effects.

Deterioration of the Brazilian and global economic conditions may, among other results:

 negatively affect global demand for cellulose and paper, or have a negative effect on these markets’ prices;

 make it harder or more expensive for the company to secure funding for operations or investments, or to refinance its debt in the future;

 harm the financial standing of customers, suppliers, or other stakeholders involved with the Company;

 reduce the return on new investments; and

 harm the financial viability of insurance companies.

Outbreaks of highly contagious diseases around the world, such as the ongoing Covid-19 pandemic, may lead to increase volatility in the world capitals market and cause downwards pressure on the world economy and, consequently, the Brazilian economy as well, with impact on the market where the Company’s shares are traded.

Outbreaks and diseases with a global potential (such as the Covid-19 pandemic, for example) may have an adverse effect on the global capital markets and economy, affecting the interests of investors in Brazilian assets, including the Company’s shares.

As discussed in foregoing item 4.1, in March 2020, the World Health Organization – WHO declared that the Covid-19 outbreak had been recategorized as a global pandemic, and government authorities in every country took steps to reduce the spread of the virus.

These measures directly affected the workforce, consumer financial capacity, and global financial markets, in addition to causing supply-chain problems (parts and raw materials). The long-term impacts of the Covid-19 pandemic are yet to be determined.

The extent of the effects of Covid-19 on the global economy and on the Brazilian economy in particular, and on the financial system and the financial and capital markets cannot yet be ascertained, which may lead to a severe crises with the potential to adversely and materially affect the Company’s business and results.

Furthermore, a significant increase in Covid-19 cases in regions of brazil where the Company has factories, and the measures that may be taken to contain the spread of the disease may, among other results, reduce output, with impacts on the Company’s operations.

Changes in Brazilian tax laws, may adversely impact the taxes levied on the Company.

The Brazilian Government frequently adopts tax-regime changes that may adversely affect the Company and its customers. This may include changes to the tax rates in force and, on occasion, the adoption of temporary taxes intended for specified Government purposes. Some such Page 49 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

changes may result in increased tax bills for the Company, which may adversely affect profitability and increase product prices, limit the ability to do business in existing and potential markets, and harm financial results. There can be no assurance that the Company will be able to maintain its predicted cash flow and profitability after any increases in applicable Brazilian taxes.

In addition, the Company enjoys certain tax benefits due to production units and investment projects in underdeveloped regions of Brazil. There are also tax benefits arising from State laws that may be subject to legal challenge based on the argument that benefits granted to the Company require the unanimous approval of the National tax Policy Council (Conselho Nacional de Política Fazendária – CONFAZ) a federal collegiate body made up of each state’s revenue secretaries.

There can be no assurance that the tax benefits that the Company currently enjoys will stand or be renewed, or that new tax benefits may be secured under favorable conditions. In the event of noncompliance with specific obligations to which the Company is subject in connection with the above tax benefits, such benefits may be suspended or reversed, or the Company may be compelled to pay the taxes due in full, with additional fines, which may have adverse results. Furthermore, there can be no assurance that these tax benefits will be renewed upon expiration, or that additional tax benefits will be secured under favorable conditions. The Federal and State governments often adopt tax regime changes, such as tax rate changes, that may adversely affect the Company and its customers. If the existing tax benefits are cancelled or are not renewed, the Company may also suffer adverse effects.

Stricter trade barriers in the Company’s main export markets may adversely affect it.

Brazilian exporters may be affected by measures adopted by importing countries to protect local producers. The Competitiveness of Brazilian companies has been causing certain countries to raise trade barriers to prevent Brazilian companies from accessing their markets or even subsidizing local producers. Trade quotas such as these may adversely affect the Company’s exports. For example, in the first quarter of 2016, the US Trade Department and the International Trade Commission announced decisions on dumping cases against several countries, Brazil included. Among other measures, the US Trade Department and the International Trade Commission applied anti-dumping margins on the sales of uncoated paper from the countries under investigation. The Company may request an annual review of the decision in line with the applicable law. Any of the above restrictions may affect the Company’s export volume and, thereby, its sales in export markets and financial standing. In the case of recently created trade barriers in Klabin’s main export markets, it may become difficult for the Company to sell its products elsewhere under favorable conditions, which may have materially adverse effects.

5.1 Risk-management policy

a) Indicate whether or not the issuer has a formal risk-management policy in place. If affirmative, indicate the body that approved it and its date of approval; if negative, provide the reasons why the issuer has not adopted such a policy;

The Company has a Risk Management Policy approved by the Board of Directors, which has as principle the alignment of strategic objectives and their structure, with the best practices of the market, in order to enable the fulfillment of the objectives established by the Management, since uncertainties and future events cannot be predicted or accurately measured and may impact business activities and perpetuity.

It should be noted that the Risk Management Policy is in the process of being revised and updated due to the recent process of creating the advisory committees of the Board of Directors.

Additionally, in addition to the formal policy for risk management, the Company adopts a series of actions and procedures in order to mitigate any risks to which it is exposed.

b) Where a risk-management policy is in place, its objectives and strategies, including:

i. The risks against which protection is sought

The risks against which the Company seeks to protect are mainly those described in item 4.1 hereof, and mainly include risks associated with:

 business strategy execution  operational activities maintenance  assets’ insurance coverage  court rulings  compliance with environmental laws  new technologies

According to Klabin’s internal methodology, risks are rated into five classes, as follows:

 Strategic: risks affecting strategic objectives and that can be strongly influenced by external factors, but are also subject to internal ones.  Financial: events that may have a negative impact on the Company’s cash flow, Financials, and access to capital.  Operational: associated with the Company’s and controlled entities’ infrastructure (processes, people and technology), affecting their operational efficiency and the effective and efficient use of their resources.  Compliance, Regulatory and Legal: risks associated with compliance with the law, given industry-specific laws and the Law more generally.  Socio-environmental: risks arising from actions or events that may lead to harm to the environment or society, with impacts on native peoples and communities and the protection of human health, of cultural heritage, and of biodiversity.

ii. Instruments used for protective purposes

Risks are assessed according to their criticality, which is defined based on two aspects:

Page 66 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

i. Impact: reflects the consequences associated with the potential materialization of risks, and ii. Vulnerability: reflects the magnitude (whether financial or not) of the exposure of Klabin and its Subsidiaries to risk.

Each risk’s impact level and the Company’s vulnerability to them are defined based on objective criteria that Klabin internally standardizes and validates.

Risk-handling procedures may include: reduce, transfer and/or share, retain, accept, or explore. In addition to aspects under the purview of the Risk Management area, Klabin embraces several actions and procedures that it deems needed to control and mitigate risks, such as:

- Management approval of the Budgeting Plant, with timely tracking; - continued and preventive asset-maintenance procedures, including annual plant stoppages and constant employee development; - valid insurance policies covering assets and lost profits (partial); - formal contingencies updating procedure with legal advisors; - supplier development, with no concentration, according to a formal quoting and decision- making jurisdictions process; - Planning and Development area to track strategies and the market in which Klabin operates; - Internal Audit area to review and track Klabin’s processes; - Controllership area to make sure that operational areas are compliant with internal control standards and ensure accurate and secure financial-statement information, including in terms of the respective controls framework; - Integrity area to act upon and track conduct-related practices and anti-corruption and anti-trust laws - General Meeting-elected Fiscal Council in place to defend shareholders’ interests.

To make sure that the main risks inherent to Klabin’s activities are identified, evaluated, treated, monitored and communicated, both strategically and operationally, Risk Management follows the steps listed next.

Risk identification is the purview of the Risk and Internal Controls Area, together with Business areas. This includes interviews, self-assessments, critical data and action-plan analysis as applicable, strategic scenarios, and the conditions of the markets in which Klabin operates.

Any risks identified are assessed as to their criticality, which depends on the respective impact and vulnerability degree as defined in the internal risk-management procedure.

After each risk’s impact and severity levels are determined based on the respective evaluation criteria, the risk is included in the “heat map” to determine its criticality and prioritize handling thereof. Risks may be rated as low, medium, high, and critical.

According to the methodology Klabin uses, the following decisions may be made about how to handle the criticality of each risk: reduce, transfer and/or share, retain, accept, and explore.

Risk handling will involve action plans from the affected areas, as well as the respective internal controls and/or metrics.

The Company’s most relevant risks are monitored by the Executive Board, Risk Commission, and Board of Directors.

Page 67 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

iii. Organizational structure of risk management

Klabin has in place the following risk-management structures and responsibilities:

Board of Directors:

 approve the Risk Management Policy;  define, support and disseminate the risk-management culture;  Approve the risks prioritized for monitoring the Company; and  resolve on any matter submitted thereto or, as it deems needed, on risks and any action plans.

Audit Committee and Related Parties:

 Evaluate the mechanisms for controlling the company's risk exposures, and may require information on policies and procedures related to the topic.

Executive Board:

 disseminate and promote the risk-management culture;  monitor the Company’s and its subsidiaries’ Risk Management based on information periodically reported by the Risk Commission, maintaining the proper functioning thereof and taking steps eventually needed to improve it;  validate the risks reported to the Risk and Internal Controls Area by the relevant Business areas;  make sure that material and human resources are available at appropriate levels to enable effective compliance with the Policy and risk-management procedures in general in the relevant Business Areas;  support the Risk Commission’s risk handling; and  support the relevant Business Areas as they carry out action plans, as well as in the implementation of any risk management-related recommendations or measures.

Risk Commission:

 recommend the Risk Management Policy to the Board of Directors and, in this context, establish the internal procedures to be used by the Company and its controlled entities for risk-management purposes;  evaluate and monitor the more relevant risks reported by the Risk and Internal Controls Area, as well as its action plans;  validate the action plans proposed by Business Areas and Executive Board once validated by the Risk and Internal Controls Area; and  report to the Executive Board and to the Board of Directors, periodically or as it deems needed, relevant information associated with risk management at the Company and its controlled entities.

Page 68 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

Risk and Internal Controls Area:

 propose the a Risk Management Policy and updates thereto;  periodically identify, monitor and control risks, including as concerns deployment of action plans;  report Risks and the respective Action Plans to the Risk Commission;  support the Business Areas and the Executive Board in designing and implementing internal controls or risk-management indicators;  perform a critical analysis of the action plans drawn by business areas for risk-mitigation purposes;  provide training programs and a communication plan in connection with Risk Management.

Business Areas:

 monitor risks associated with the respective activities and inform the Risk and Internal Controls Area, through the manager in charge, of any change in their business processes that may give rise to new risks, or change the status of risks already identified;  support the Risk and Internal Controls Area in risk identification,  support the Risk Committee (or Commission) in risk handling;  carry out action plans;  establish appropriate risk-management controls and/or indicators; and  make sure that the recommendations from the Risk and Internal Controls Area, the Risk Committee (or Commission) and the Executive Board are effectively followed and that deviations from the Risk-management policy and internal procedures applicable to risk management are readily identified and reported.

c) Adequacy of the operational and internal controls structure while determining the selected policy’s effectiveness.

The effectiveness of the Company’s selected procedures lies in the verification, oversight and critical observation of how those procedures are carried out, involving preparation of monitoring reports and risk-checking by the Risk Management area and processes review by the Internal Controls area. In addition, it is the purview of Internal Audit to independently report the results of its own analyses to the Business areas by means of specific reports to include evaluation of the Company’s Risk Management process.

5.2. Market Risk Management Policy

a) Indicate whether or not the issuer has a formal market risk management policy in place. If affirmative, indicate the body that approved it and its date of approval; if negative, provide the reasons why the issuer has not adopted such a policy.

As indicated in item 5.1 hereof, the Company has a Management-approved risk-management policy in place that lists risk rating types, including market risks.

It should be noted that the Risk Management Policy is in the process of being revised and updated due to the recent process of creating the advisory committees of the Board of Directors, which took place in November 2020, and the process validation and risk prioritization in December 2020 by the Board of Directors Management.

b) The market risk management policy’s objectives and strategies, where applicable, including:

i. market risks against which the Company seeks protection

The Company and its Subsidiaries are parties to operations that involve financial instruments, all of which are booked in equity accounts, and are intended to meet their operational needs, as well as to reduce exposure to financial risks, in particular credit, currency and interest rate risks.

Management does not expect to increase or reduce risks but simply seeks alternatives to control and mitigate risks.

The main market risks capable of affecting the Company’s operations are:

Credit risk and funds allocation risk

These risks are managed based on specific customer acceptance standards, credit review, and establishment of exposure limits by customer. Overdue invoices are promptly monitored. In addition, Management-approved analyses and standards apply to financial investments with financial institutions and the investment types available from the financial market, pursuing conservative and safe investing.

The Company has since April 2017 maintained insurance against domestic and international market receivables for all of its business units, except wood customers of the forest unit, in addition to certain customers that fail to meet specific risk requirements, such as continuity and liquidity, which the insurance company analyzes for incorporation under the policy. The Policy currently in force expires in August 2021.

Exposure to foreign exchange variations

The Company has foreign currency-denominated operations (substantially US Dollars) that are exposed to market risks arising from changes in the foreign exchange rates for the respective currencies.

The Company maintains no derivatives as hedging instruments against the long-term foreign exchange rate exposure. To address this net exposure, the Company maintains a sales plan whose projected export revenues flow is an approximate USD 1 billion annually and receipts from it, if realized, exceed or approximate the payments flow associated with the respective Page 70 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

liabilities, offsetting the cash effect of this future foreign exchange exposure.

The Company’s only derivatives are currency and interest rate swaps pegged to issues of certain letters of export credit and the 12th debentures issue.

For sensitivity-analysis purposes, Scenario I assumes the market forward rate in force during preparation of the financial statements as of December 31, 2020; Scenario II adjusts the rate by 25% and Scenario III adjusts it by 50%.

All other variables remaining constant, the table below shows the simulated effect of foreign exchange variations on the balance sheet:

Net effect on finance results (225,144) (4,791,420) (9,328,947) Interest rate risk

The Company has loans from BNDES that are indexed to the TJLP, loans with other financial institutions that are indexed to the Libor, and working capital and financial investments indexed to the CDI, exposing the respective assets and liabilities to interest-rate variations. The Company has not executed derivatives to hedge/swap against this risk, but consistently monitors market rates to determine an eventual need for derivatives to protect against the risk of interest rate volatility. Furthermore, the Company believes that the high cost associated with securing pre-fixed rates under the Brazilian macroeconomic scenario justifies its choice of floating rates.

For sensitivity analysis purposes, the Company assumes for Scenario I the rates in force on dates close to the release of its financial statements for December 31, 2020, using the same rate for SELIC, IPCA and CDI, as the rates are very similar; Scenario II adjusts these rates by 25%, and Scenario III adjusts them by em 50%.

All other variables remaining constant, the table below shows the simulated effects of interest rate changes on income 12 months into the future:

Net effect on finance results (117,696) (29,424) (58,849)

Liquidity risk

The Company tracks the risk of a scarcity of funds, managing its capital by means of a recurring liquidity planning tool so that there will be funds available to duly meet its obligations, which are largely concentrated in financing agreements with financial institutions.

The table below shows the maturity schedule of the Company’s financial liabilities according to the consolidated balance sheet, including principal and upcoming interest owed on the transactions, calculated using the interest rates and indices in force as of December 31, 2020 (amounts in BRL thousands):

2027 And 2021 2022 2023 2024 2025 2026 Total subsequent Suppliers (2,003,029) (2,003,029) Financing/Debentures (1,435,979) (2,335,344) (2,095,154) (2,832,020) (2,930,750) (3,530,121) (23,751,961) (38,911,329) Total (3,439,008) (2,335,344) (2,095,154) (2,832,020) (2,930,750) (3,530,121) (23,751,961) (40,914,358) Budget forecasts for the coming fiscal years as approved by the Board of Directors show the Company’s ability to honor its obligations, if realized.

ii. Hedging strategy The Company undertakes no operations involving financial instruments for speculative purposes, nor specific long-term cash flow hedges. The Company only has two swaps in place, pegged to specific operations (two export credit notes and the 12th debentures issue) originally issued in Brazilian Reais and with swaps being used for conversion into US Dollars as a means to optimize the banking costs involved in the operation.

These risks are managed by means of strategies drawn by the Financial Area and approved by the Company’s Management, together with the establishment of control systems and position limits. To face this net liability exposure, the Company has in place a sales plan with export revenues of approximately USD 1 billion per year, the proceeds of which, if realized, are greater than or close to the payments flow of the respective liabilities, offsetting this exchange-rate exposure’s cash effect in the future.

iii. Hedging instruments In December 2018 the Company raised a new export credit note with Banco Bradesco in the amount of BRL 1,879 million, maturing in 2026 and paying 114% of CDI, without collateral or covenants, pegged to two FX-interest rate swaps in the same amount, but denominated in USD Page 72 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

and paying interest at 5.6%, with the same maturity as the credit note. None of the instruments may be separately redeemed. In May 2020 the Company raised another BRL 1,125 million in the same manner and under the same terms and conditions.

In March 2019, the Company executed a swap with Banco Itaú with an asset position of 114.65% of CDI and a liability position in USD at .40% p.a. The operation is pegged to the 12th debentures issue, in the amount of BRL 1 billion, and executed in April 2019.

Gains and losses from derivatives are market to market and correspond to the respective fair value as recognized in financial results.

The operations were executed to optimize banking costs and are not for hedging purposes.

Furthermore, starting on January 04, 2021, the Company adopted the cash flow hedge accounting policy, deeming its highly probable revenues in US Dollars as hedge subjects and outstanding loans and financings denominated in US Dollars as hedge instruments. The purpose of the policy is to mitigate the effects of exchange rate variations on the Company’s results, with the effects of exchange rate variations on loans and financings involved in the hedge allocated to shareholders’ equity until the effective liquidation thereof, as export revenues occur.

iv. Parameters in place for managing these risks Information concerning setting limits for market risk exposures are dynamic and depend on the Company’s chosen strategy.

As concerns credit risk, the Company relies on its Credit Policy, which sets parameters for credit to be extended to each customer. The risk associated with the use of funds is addressed by the Financial Investments Risk, which determines the Company’s allowed banks and operation types. Liquidity risks are addressed by the Company’s Financial Debt Policy. Public policies are available on the website: https://ri.klabin.com.br/governanca-corporativa/estatuto-codigos-e- politicas/.

Exchange rate and interest rate variation risks are under continued monitoring by the Financial area and reported to the CFO for decisions regarding the need to set exposure limits not provided under a specific policy as a means to protect the Company and its cash flow against any such risks.

v. Whether or not the issuer operates financial instruments for purposes other than hedging, and what these purposes are The Company undertakes no operations involving speculative financial instruments or specific equity-hedging instruments.

vi. Organizational structure for market risk management control The Company manages its risks in an ongoing manner, requiring compliance with formal, Management-approved policies that drive risk-related transactions. It relies on a Risk Commission made up of members of the Executive Board and responsible for risk assessment and management, together with the Risk and Internal Controls Area, the Internal Audit department and an Integrity area. This structure manages and verifies policies, procedures and Page 73 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

practices applicable to risk management.

In addition, monthly indicators are drawn to consolidate all of the Company’s financial transactions and operational data, so that Management can monitor risk exposure and verify the effectiveness of risk-monitoring actions and policies

5.3. Description of internal controls

a) Principal internal control practices and their effectiveness, indicating any imperfections and the steps taken for correction;

The Company operates at BM&FBovespa’s level 2 corporate governance and is a component of the Business Sustainability Index (Índice de Sustentabilidade Empresarial – ISE) portfolio, a tool for comparative analysis of the corporate sustainability performance of BM&FBOVESPA- listed companies, based on economic efficiency, environmental balance, social justice and corporate governance for companies that meet the index’s acceptance criteria.

The Company’s principal internal control practices involve its entire framework of procedures, formal policies, Management-approved purviews, audit reviews, process mapping based on key area controls, integrity assessments, analysis of access security against virtual attacks, analysis of access to SAP system operational transactions, and analysis of function segregation conflicts. The areas that carry out these activities are: Information Security, which is managed by the Information Technology department; the Internal Audit department; the Integrity area; and the Risk Management and Internal Controls area.

b) Organizational structures involved;

The organizational structure involved in the assessment of the internal controls environment includes: (i) the Risk Management and Internal Controls area; (ii) the Integrity area; (iii) the Information Security area; (iv) Internal Audit; (v) Audit Committee; and (vi) Controllership, materializing the concept of three lines of defense from the business areas to the evaluation areas.

Evaluation of the internal controls environment is primarily the responsibility of the Risk Management and Internal Controls area.

The area maintains a tracking schedule with the independent auditors to discuss and present measures to address points raised in the Letter of Recommendations, as well as to carry out walkthroughs in connection with processes that the Independent Auditors deem relevant. Therefore, together with the independent auditors, the Company monitors the presence of any control deficiencies identified in audit exams during the fiscal year, and remains vigilant to act preemptively and correct deficiencies.

The Integrity area prevents detects and remedies breaches of the Code of Conduct and other policies where noncompliance may go against Klabin’s integrity principles and values. The area is also in charge of managing the Company’s Integrity Program, structured as several pillars that contribute to strengthening ethical conduct within the Company. The pillars are: Senior Management commitment and support; integrity training; third-party reputation assessment; integrity risks assessment; communication; Code of Conduct, Policies and Integrity Procedures, Integrity Channel and Ombudsmanship; Integrity Commission; and continued monitoring.

Information security is monitored by the Information Technology area, including dissemination of the policy to all of the Company's employees, maintaining system adherence, including operational continuity plans, incident management, and information security crisis management.

Internal Audit is a supporting department that reports to the Chairperson of the Board of Directors. It has the autonomy and independence to define and carry out evaluation and process Page 76 of 348

d) Internal controls deficiencies and recommendations present in the substantiated report prepared and submitted to the issuer by the independent auditors pursuant to CVM regulations on independent audit registration and exercise;

The internal controls report prepared by the independent auditors for the year ended December 31, 2020 only presents a significant deficiency related to the weakness in the review control and timeliness of recording specific unusual transactions.

e) Comments of the Executive Officers on deficiencies indicated in the substantiated report prepared by the independent auditors and on corrective steps taken;

Management has worked intensively over the past few years to review the controls implemented and their effectiveness in the face of new scenarios resulting from the Company's growth. In 2020, the Company identified an event that resulted in the lack of proper accounting treatment, correcting it within the year. The latter demonstrated that internal controls have evolved, being capable of correcting and adapting the Company's accounting records.

During fiscal year 2021, the Company will carry out a review of practices and the mapping of its accounting processes using the experience of market specialists. Although the event identified and corrected in 2020 was classified as immaterial for the Company, the review works aim to certify that all processes have been duly reviewed together with their respective operating areas, that the flow of accounting information is effective, and that any complex transactions or unusual ones without proper accounting records are identified and corrected.

5.5. Material changes

In the fiscal years 2020, 2019 and 2018 the main market risk affecting the Company’s results were BRL-USD foreign exchange rate fluctuations, creating significant negative and positive effects on the periods’ income because of the foreign currency-denominated liability exposure made up significantly of foreign currency financing, as the Figure next shows:

Amounts in BRL thousand Fiscal Year ending 12/31/2020 12/31/2019 12/31/2018

FX variation – assets 582,031 318,800 156,759 FX Variation - liabilities (4,202,765) (729,071) (2,155,558) Net effect on financial income (3,620,734) (410,271) (1,998,799)

In fiscal year 2020, the exchange rate varied up, reaching yearend at BRL 5.20/USD (BRL 4.03 as of December 31, 2019). This change had a BRL 3.620,7 million negative impact on net foreign exchange variations.

In fiscal year 2019 the exchange rate varied up, reaching yearend at BRL 4.03/USD (BRL 3.87 on December 31, 2018). This change had a BRL 410.3 million negative impact on net foreign exchange variations.

In fiscal year de 2018 the exchange rate varied up, reaching yearend at BRL 3.87/USD (BRL 3.31 on December 31, 2017). This had a BRL 1,998.8 million negative impact on net foreign exchange variations.

Furthermore, the Company has a natural hedge from operations that enables honoring foreign currency obligations through cash flows from exports, which, when made, eliminated the cash effect of foreign exchange variations, so that the change in the balance of debt owed corresponds to the variation in receivables from exports. The Company purchases no derivatives for this specific purpose.

The only derivative purchased by the Company concerns currency and interest swaps pegged to the issue of a certain export credit note and a certain debenture that converts debt from BRL into USD.

For fiscal year 2021, the Company adopted cash flow hedge accounting for highly probable expected transactions, designating its revenues in US dollars as hedge object for debt (hedge instrument) also denominated in US Dollars|. The purpose of the practice is to equalize the effects of foreign exchange variations on the income statement as they are effectively recognized along with their cash effects.

Despite the foregoing, the Company is not aware of any material changes to its risk exposure, and adopts a practice of constantly monitoring business risks capable of adversely impacting its operations and results, including macro-economic and sectoral scenario changes capable of affecting its activities, analyzing price and economic activity indices, as well as the supply of and demand for the Company’s products.

6.3. Brief history of the issuer:

Klabin Irmãos S.A.’s history of more than a century begins in 1899, when it was founded by the Klabin-Lafer family in São Paulo to sell paper, office supplies and printing materials. Three years later with business prospering, the Company leased a small printer’s paper plant and made its debut in the segment in which it operates to this day: the production of paper. Companhia Fabricadora de Papel was incorporated in 1909. By the 1920s, it had become one of the three largest paper manufacturers in Brazil. The strategy adopted by the entrepreneurs was one of innovation, requiring regular trips to Europe in search of new production techniques. With this end in view, the company took a great leap forward in 1934, acquiring Fazenda Monte Alegre in the state of Paraná to build Brazil’s first integrated pulp and paper mill, called Indústrias Klabin do Paraná de Celulose (IKPC). The company’s first planted forest plan had its beginnings in 1943, initially using araucaria and eucalyptus, followed by pine in the 1950s, with the inauguration of large pine wood plantations. Parallel to this, in 1946, manufacturing activities began with the production of newsprint and packaging paper. This was a landmark event in the history of the sector in Brazil. For the first time, part of domestic market demand was to be supplied by an indigenous manufacturer. Currently, the Company is the largest producer and exporter of packaging paper in Brazil. It is leader in the segments for paper and paper boards for packaging, corrugated paper and industrial bags as well as producing short fiber, long fiber and fluff pulps in one of the most modern and sustainable industrial plants in the world, unveiled in 2016. Klabin’s annual pulp and paper production is 3.7 million tons. The Company has 23 industrial units in Brazil and one in Argentina as well as commercial offices in ten Brazilian states and in North America and Europe. Klabin directly and indirectly employs approximately 25 thousand. The Puma II Project was approved in April 2019, and consists in the construction of two packaging paper machines with integrated cellulose production in the city of Ortigueira – PR, where the Puma Unit is also located. The machines’ total capacity will be 910 thousand annual tons of paper, with BRL 12.9 billion in gross investment. The project is divided into two phases, with the first machine set to start up in July 2021 and the second in the second quarter of 2023. The first stage consists in the construction of a main fiber line to produce 100% eucalyptus non- bleached cellulose integrated with a kraftliner machine with the capacity for 450 thousand annual tons. The second contemplates the construction of a complementary fiber line integrated with another paperboard machine, with capacity of 460 thousand tons per year and expansion of some support structures. As the leader of the Brazilian corrugated board and sack kraftboard markets, the company offers exclusive products tailored to the need of the client and is equipped to meet the most demanding requirements. In line with world standards, Klabin’s paper board product is manufactured from a mix of pine and eucalyptus which is transformed into high value-added paper board with greater rigidity, tear resistance and printing quality. Klabin is a global benchmark for forestry management and productivity due to the care taken since inception to ensure that its pine and eucalyptus plantations are interspersed with preserved native forest in a mosaic format. The formation of this ecological corridor protects the fauna and flora, as well as preserving the river headwaters. Klabin has 266 thousand hectares of planted forests and 243 thousand hectares of preserved forests. That is, more than 40% of its total area comprises indigenous forest. In 1998, the company was the first in the Southern Hemisphere in the pulp and paper sector to receive FSC® (Forest Stewardship Council) certification for its Forestry Unit in the state of Paraná. Today, the Company’s forests and all its productive

Page 86 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

processes are certified by the entity – confirmation that it conducts its activities according to the highest social and environmental standards. The strategy and actions in Klabin’s business plan include climate change mitigation and adaptation. To this end, Klabin has signed up to the United Nations “Business Ambition for 1.5°C” global initiative, under which it commits to a science-based target for reducing emissions, contributing to the collective efforts of containing temperature increases to 1.5°C. In addition, in relation to emissions from its productive processes, the Company successfully reduced specific emissions by 60% (kgC02eq/ton product) between 2003 and 2019. Furthermore, Klabin has a carbon balance of 4.7 million, that is, its planted and native forest stands remove and store more carbon (11.1 kgC02eq/ton product) than its industrial processes emit (6.4 kgC02eq/ton product). In 2016, Klabin voluntarily joined the United Nations’ Sustainable Development Goals (SDG). This initiative gathers governments, civil society and the private sector around a global agenda for people, the planet, peace and prosperity, setting global priorities and aspirations for 2030. Since then, Klabin has been working not only to demonstrate the initiatives it already has in place supporting this agenda, but also to identify new opportunities for action and foster incresing integration of the SDGs into the Company’s strategic plan. In 2020, the Company made progress in its commitment to the UN Sustainable Development Goals. To ensure and catalyze their implementation at the Company, Klabin launched the Klabin Sustainable Development Goals (“Objetivos Klabin para o Desenvolvimento Sustentável” – KODS), with short-, medium- and long-term targets organizing environmental, social and governance milestones by priority and adherence to the strategic growth plan and the Company’s long-term vision. All of these initiatives by Klabin are public and reinforce the Company’s commitment to transparency before the market, as well as its egalitarian treatment of shareholders. As a result, it has since 2014 been a component of corporate governance level 2 of B3, the São Paulo stock exchange. This segment lists the shares of companies that embrace distinctive governance practices. The company has also been a component of B3’s Corporate Sustainability Index for eight consecutive years. The IS undertakes a comparative analysis of the corporate sustainability performance of B3 listed companies, based on economic efficiency, environmental balance, social justice and corporate governance. Klabin was selected as a component of the 2020/2021 edition of the Dow Jones Sustainability Index (DJSI) portfolio. The Company thus enters the index in two categories, World Index and Emerging Markets Index, and is the only Brazilian company listed in the global category. This recognition is a milestone for Klabin, the fruit of 120 years of commitment to the environment, care for people, and management driven by climate science, with bold targets for greenhouse gas emissions reduction and efficient use of natural resources. Another important 2020 milestone was the approval, at the General Meeting of November 26, of the takeover of Sociedade Geral de Marcas Ltda. (Sogemar), thereby ceasing the payment of royalties for the Klabin brands. In addition to creating shareholder value, the operation was an important step towards improved corporate governance practices because of the cessation of a relevant transaction with related parties. The process was conducted in line with the recommendations of a task force made up exclusively of independent Directors with no direct or indirect stakes in Sogemar, relying on independent valuations and informational disclosure for due consideration of minority shareholders. Subsequently, in December, the Company approved the creation of three advisory committees to the Board of Directors: the Audit and Related Parties Committee, the Sustainability Committee and the Compensation Committee with the election of the respective members. Also on the corporate governance front, two financial Page 87 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

policies were approved and released, to govern debt and dividends, adding even more transparency before the Company’s relevant publics. At 122 years, Company is proud to remain under the control of its founders’ family and to be a Brazilian company with international recognition for the high quality of its products and the commitment to sustainability that is a part of its DNA.

6.6. Other relevant information

Projeto de expansão - Puma II

As announced to the market in a Material Fact notice of April 16, 2019 and May 5, 2021, approval was given for work to start on a capacity expansion project in the packaging papers segment known as the “Puma II Project", covering the building of two paper machines with integrated pulp production, located at Klabin’s industrial unit in Ortigueira (PR) (Puma Unit).

The installation of the Puma II Project will be divided into two phases:

(i) Phase One – consists of the construction of the main fiber line to produce unbleached pulp integrated with a kraftliner paper and white kraftliner paper machine. The products will be sold under the eukaliner brand, with an annual capacity of 450 thousand tons. This phase also includes complementary supporting facilities for the recovery and utilities areas’ new lines and plants.

(ii) Phase Two – covers the construction of a complementary fiber line integrated to a kraftliner paper machine with an annual capacity of 460 thousand tons and the expansion of certain support facilities.

According to the construction schedule, works on each stage will last for 24 months, and works on the second phase will begin as soon as the first is completed. Consequently, startup of the first machine is slated for the second quarter of 2021, and the second machine is expected to begin operations in the second quarter of 2023.

Gross investment has been budgeted for the construction of the Puma II Project at BRL 12.9 billion, subject to exchange rate oscillations and inflation restatements, to be disbursed between 2019 and 2023. Of this total, approximately BRL 1.2 billion concern recoverable taxes. Since the bulk of the equipment is to be installed during the first phase of the project, approximately two thirds of the disbursements will take place between 2019 and 2021. The project will be financed from the Company’s cash position and cash flow from existing business. Additional funding may come from financing as long as the conditions are attractive in terms of cost and duration.

7.2. Operational segments which have been disclosed in the last three financial statements for the close of the fiscal year or when the case, in the consolidated financial statements:

a) Products and services sold

In 2003, the Company underwent a financial restructuring process and focused on its current core businesses of manufacturing packaging papers and paperboard and paper packaging. Today, the Company’s products are: kraftliner papers (virgin fiber paper), testliner (recycled paper) and coated paperboard, corrugated cardboard packaging and industrial bags, together with long fiber pulp, fluff and short fiber pulp. The Company also operates in the forestry sector with the sale of wood logs.

The Company is a pioneer and leader in the production of kraftliner paper in Latin America in addition to being the largest producer and exporter of packaging papers, accounting for more than half of Brazilian exports of these products in 2019. Kraftliner paper manufactured by the Company exported to more than 60 countries and, together with recycled paper, provides integrated supplies to Klabin’s corrugated board packaging plants.

The Company’s paperboard is produced from a mix of short (eucalyptus) and long (pine) fibers, lending packaging excellent resistance and printing quality. All the Company’s plants have Chain of Custody certification from the FSC (Forest Stewardship Council).

The Company is also a leader in the corrugated board sector in Brazil and has the largest installed capacity in the domestic market. The Company’s packaging products serve various segments of the economy, providing total protection to transported products.

The Company is also a leader in the manufacture of industrial bags of recognized quality, offering customized service to clients in several market segments, notably civil construction, food, chemical products and agribusiness.

In addition to paper segments, the Company’s Forestry Unit sells logs harvested from the planted forests to the laminates industry and saw mills. These processes ensure the reliability and low cost of products, always in line with the Company’s sustainability policy. The Company’s forests are certified by the FSC (Forest Stewardship Council), and Klabin was the first company in the pulp and paper sector in the Southern Hemisphere to receive FSC certification for its forests in the state of Paraná in 1998.

In 2016, the Company began operations at its new pulp plant (Puma Unit), located in Ortigueira, state of Paraná. The Puma Unit has a production capacity of 1.5 million tons of pulp, of which 1.1 million tons are bleached short fiber pulp (eucalyptus) and 400 thousand tons are bleached long fiber pulp (pine), part of which is converted into fluff pulp. The industrial unit is the only one in the world designed to produce all three fiber types. Output at Klabin contributes to the substitution of fluff pulp imports, an important raw material used in diapers and sanitary pads, representing hard currency savings for the country.

b) Revenue from the segment and its participation in the Company’s net revenue

The table below shows the amounts arising from each of the Company’s activities, as well as the respective percentage of such amounts on net operating revenue in the years ended

Gross revenue (including wood) in 2020 was BRL 13.7 billion. Net revenue was BRL 11.9 billion, up 16% from 2019. Export revenues were 41% of total net revenues.

Gross revenue (including wood) in 2019 was BRL 11.9 billion. Net revenue was BRL 10.3 billion, up 3% from 2018. Export revenues were 40% of total net revenues.

Gross revenue (including wood) in 2018 was BRL 11.5 billion. Net revenue was BRL 10.0 billion, up 20% from 2017. Export revenues were 45% of total net revenues.

c) Profit and loss resulting from the segment and its participation in the Company’s net income

The Company does not calculate the profit or loss for each one of the segments separately since the functions of its operational structure are shared across all segments. It is therefore not possible to allocate the expenses associated with these activities for each business. Additionally, the Company’s cash is concentrated at its corporate unit and not segregated among the business units.

However, Klabin does disclose operating results before the financial result by operational segment as shown below.

7.3. Products and services corresponding to the operational segments disclosed in item

a) Characteristics of the production process

The Company is a vertically integrated producer. Its requirements for wood are satisfied principally from its own planted forests which are planted and managed by the Company and certified by the FSC (Forest Stewardship Council). It produces pulp and subsequently integrates it in paper machines. Some of the paper is converted in own conversion units into corrugated board packaging and industrial bags, the remainder being sold to the domestic and export markets. In addition, the Company produces bleached short and long fiber pulp, which is partly converted into fluff pulp and partly sold on the domestic and export markets.

The processes employed are those customarily used by the sector and fine-tuned to the conditions of each plant in relation to the type of wood and the end use of the fiber. Technology employed is largely from the Northern Hemisphere, notably countries such as Germany, Sweden, Finland and the USA. Since Brazil is an important pulp and paper producer, all the leading world producers of equipment for the sector have manufacturing plants in the country.

FORESTRY

Klabin produces wood from eucalyptus and pine planted forests. The production process begins with seedlings raised from vegetative propagation (cloning) or seeding, which takes place in own or outsourced forestry nurseries. The production of seedlings normally takes between 3 and 5 months.

Seedlings are planted following the preparation of the soil and the first fertilizing. During the initial phase of planted forest installation, the areas must be fertilized and undergo weed and pest control. The initial plantation phase takes about one year for eucalyptus and three years for pine. Following this period, the forest is consolidated and surveillance is necessary as a precaution against events which may prejudice productivity.

At felling age (between six and seven years for eucalyptus and 14-15 years for pine), the forest is harvested using a mechanized process that relies on machinery for cutting, dragging and processing of the wood. The logs produced are loaded onto and transported on trucks to the wood yards located at the manufacturing plants.

The forestry area also produces wood in logs that are sold to regional industries (sawmills and laminators). In this case, the forest is harvested after about fifteen years (eucalyptus) and twenty years (pine).

Throughout this process, rigorous environmental and social criteria are adopted so that production in the forest plantations takes place sustainably. These operations involve care with the soil, water and biodiversity, as well as the communities with which the managed relate. Forestry management at Klabin is FSC (Forest Stewardship Council) certified.

Principal equipment

In forest formation, the principal equipment used involves soil preparation machinery (tractors and towed implements). In the harvesting process, by its turn, the equipment is grouped into modules comprising a directional feller, a skidder, a shovel and two processors.

Reference Form- 2021- KLABIN S. A. Version: 7

PULP

In the market pulp and fluff pulp production process, the fibers from the bleaching process are transferred to the drying machine, where low-consistency fiber suspension is placed on a screen to drain excess water and form sheets. The sheets are roll-pressed to remove excess water prior to entering the drier. Having passed through the drier, the sheet already has water content in line with market standards. Eucalyptus pulp sheet is cut into smaller sizes and sheet bales are packed prior to shipment. Pine pulp sheets may be baled (the same process as eucalyptus) or transformed into fluff pulp reels.

Principal equipment

In the production process, the most important pieces of equipment are the digestors (pulp production), the recovery boiler (chemicals recovery and steam generation), the turbine generators (electric energy production) and the drying machines.

PAPER

The Company uses eucalyptus and pine fibers to produce packaging papers. Pulp production consists in the separation of the fibers from other components of the wood, more especially lignin, a substance which binds the cells together and lends wood its rigid structure. Wood chips are treated with lye and other chemicals in pressure vessels known as digestors. This is the chemical, or kraft, process and the one most used in the pulp industry.

Following the digestor stage, the cellulose fibers are separated from the dissolved wood components. Still with a brown color, the fiber is delivered to the following stage, directly to the paper mill or for bleaching. The dissolved components form the so-called black liquor which is sent for the recovery of chemicals and burning off of organic content (lignin and other wood components), generating steam and energy.

Bleaching is a process used to continue the de-lignification that began with cooking and lend cellulose its white color. It relies in oxidizing agents such as oxygen, ozone and peroxides to remove the residual lignin from the fibers and whiten the cellulose paste. The Company uses a process of elementary chlorine-free bleaching (ECF) at its Monte Alegre Plant. This process ensures that highly polluting dioxins are formed and are released as plant effluents.

The transformation of the pulp into a flat, thin and cohesive structure – paper – takes place using equipment and operations collectively referred to as paper mills. The process begins with the treatment of the fibers, a phase called paste preparation where fibers are run through equipment that develops the physical properties of the fibers, separating out impurities and blending in other types of fibers and additives used in paper manufacture such as mineral fillers, starches, glues, dyes. Each paper type has a distinct formula in accordance with its end-use requirements. This phase takes place in an aqueous medium and, after this treatment, the fiber suspension is sent to the paper mill for final characteristics, such as grammage (fiber mass per unit of area), drying and surface finishing.

Recycled papers

Used in the production of corrugated board packaging and also sold to other packaging companies. About 15% of the raw material is supplied from the corrugated board packaging conversion units and the remainder is acquired from OCC suppliers. Products:

EkoFlute – Fluting paper is made with 100% recycled fibers and receives during the manufacturing process, chemical additives which increase water resistance. Recommended for manufacture of fluting for corrugated board packaging. Not recommended for direct contact with foodstuffs.

Ekoliner – Made from corrugated board shavings as well as fibers from trims and scraps from the manufacture of the Company’s virgin fiber papers. Recommended for internal use in corrugated board packaging as fluting support.

Principal equipment

The most important pieces of equipment in the production process are the digestors (pulp production), the recovery boiler (recovery of chemicals and steam generation), the turbo- generators (power production) and the paper production machines.

The production units undergo annual 7-10-day stoppages for major maintenance and inspections of equipment, especially those working under conditions of pressure and temperature such as digestors and boilers. During these stoppages, worn down equipment is replaced and technological upgrades are introduced to improve performance, ensure operational safety and increase productivity. Preventive and corrective maintenance is also carried out on a monthly basis on specific equipment and on the paper mills.

The main pieces of equipment at the Company’s paper and pulp production units are as follows.

CONVERSION

(i) Corrugated Paperboard Boxes and Sheets

The manufacture of corrugated paperboard packaging involves a chemical, thermo-mechanical process. The paperboard is processed through various stages before producing the end packaging product. During this process, the paperboard is pressed in layers, mechanically fluted, cut, creased, printed with water-based ink and folded.

The process begins with the combining of various layers of paperboard to form a rigid sheet. In this phase, one or two layers are joined alternately to the rest only after they have undergone a process of fluting. For this purpose, the paperboard receives an application of starch-based glue and then heat treatment. This fluting provides rigidity to the paperboard sheet. The flutes can be of various sizes giving the corrugated paperboard different thicknesses (approximate measures, depending on the thickness of the paperboard):

 Flute "E": 1.3 mm thick  Flute "B": 2.8 mm thick  Flute "C": 3.8 mm thick  Flute "A": 4.5 mm thick Paperboard can also be dual-fluted, which provides additional rigidity. Normally, "C" and "B" (most frequent) and "A" and "C" fluting combine. The corrugated paperboard sheets are then processed into packaging. During the process, the sheets are printed with flexographic (water- based) ink. The paper types used to manufacture corrugated paperboard are specially made for conversion into packaging and may be virgin-fiber (kraft) type, or recycled-fiber. Different grammages are used from 100 to 420 g/m², according to the resistance requirements of the product to be packaged.

Principal equipment

Flute laminating machine: transforms paper reels into corrugated paperboard sheets and normally producing paperboard sheets with B, C, E, AC and CB flutes.

Printers: transform corrugated paperboard sheets into packaging. The Company has a modern

printing press park comprising printing presses of the "rotary cutting-creasing" type (using forms for cutting and creasing the paperboard, supplying as a finished product, unfolded packages) and "folder-gluer machines" (machines, which can be repositioned, producing cuts and creases), dispensing the need for forms, supplying as the end product, folded packaging with glued ears). The Company is able to print in up to five reticulated polychromatic colors.

Other equipment

 Stapling machines, gluer, machines for accessories and palletization;  Utilities (boilers, starch glue kitchens, baling presses, scrap shredders, etc.)  Effluent treatment plants

(ii) Industrial Bags

Industrial bags are processed through a range of different equipment to produce the finished packaging. The paper is printed flexographically with water-based ink, cut, glued with vegetable starch or PVA glue, layered, folded, closed for filling-valve insertion, counted and bundled for shipment to the end customers.

Printing or pre-printing process

Reels of sack paper are placed on reel unwinders, run through rollers and the printing apparatus, where application of ink takes place. This may be up to eight colors, depending on the design and layout provided by the client. The paper is then run through a drying and re-spooling system. The spools are tagged and returned to inventory, where they await processing at the tuber, in line with the production schedule.

Printing or pre-printing process

Reels of paper for bags are placed on a reel unwinding machine, passed through rollers and then on to printing which may be in as many as eight colors in accordance with customized design and layout. Subsequently, the paper is introduced into a drying and rewinding system. The reels are then identified and returned to stock to await processing in the tuber in line with the production program.

Tuber process

The tuber process begins by placing the reels on the reel unwinding machine. The first sheet may pre-printed or printed directly during this process. Then the paper is processed through rollers for correcting reel positioning for application of glue between the sheets, cut (perforated) and the edge glue applied for forming the tubes. The next step in the manufacturing process is the tube forming table and subsequently the perforating knife to separate the individual tubes. The tubes then proceed along a moving conveyer belt exit table where they are counted and bundled. The tube bundles are then dispatched along automated conveyor belts to the gluer feeder table.

Gluer process

The individual tubes are fed automatically through the creasing and opener stations and tube bottomer unit. The upper and lower bottoms are glued and a filling valve applied in the upper

Page 101 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

bottom layer. The bottoms are then sealed and the product then proceeds for drying and pressing. The bags are counted and stacked in bundles and then go for palletization, which may be manual or automated.

Process of lashing the pallets

In this process, the pallets released for shipment are baled with plastic or according to customer requirements, lashed and send for shipment in accordance with established dates.

b) Characteristics of the distribution process

The Company’s products are exported to more than 50 countries through local representatives, trading companies specialized in paper products and also through direct sales coordinated by an in-house sales team established at the head office in São Paulo. Sales to the domestic market are nationwide. Exports go to Europe, South America, North America, the Middle East, Africa and the Far East. Supply logistics largely involve road transportation to the domestic market and Latin America and by sea to other regions.

FORESTRY

The logistics for delivery of wood to the yards of the Company’s own pulp and paper plants as well as the sale of logs is entirely via road haulage.

PULP

Klabin’s short and long fiber pulp is sold on the domestic and export markets to clients in several segments such as: tissue (toilet paper, paper handkerchiefs, napkins), printing and writing paper (books, newsprint, catalogs), among others. The Company’s fluff pulp is sold both on the domestic as well as the export markets to clients making infant and geriatric diapers, sanitary pads and nonwovens.

The Company currently exports to more than 40 countries, mainly through its São Paulo-based sales team, as well as representative firms and agents, and directly to some clients under global distribution agreements. The logistics of supply is largely via road to the domestic market and Latin America and by sea for other world markets.

PAPER

in the domestic market, Klabin sells to clients in several segments such as: corrugated paperboard, manufacturers of tubettes, makers of abrasives (3M, Saint Gobain) and manufacturers of non-extensive bags. Sales are made through a domestic sales team at the Company’s head office in São Paulo. The Company offers a complete line of papers for corrugated paperboard boxes whether made from virgin fiber such as kraftliner paper and white top liner or papers from recycled fibers used as inner layers or recycled face paper, known as testliner.

Sales to the European market are made on a delivered duty unpaid basis and have the logistical support of an office in Vienna. Shipments are coordinated on a just-in-time basis for all European clients out of this office with the exception of the markets of Greece and ,

Page 102 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

where sales are made CIF port of destination. Sales to the international market are made through local agents, exclusively dedicated to the Company’s products in the leading markets. Some markets are directly served by the commercial team headquartered in Brazil. International clients are basically corrugated paperboard manufacturers.

Coated board sales (reels and sheets) are centered at head office in São Paulo (SP). Global sales are made through the intermediary of proprietary salespersons, sales representatives and trading companies and cover several segments of the coated board packaging industry for consumer products. The competition, also worldwide, involves local producers (from the respective regions covered) as well as international producers (inter-regional). Sales in the domestic market are covered out of the Monte Alegre (in Telêmaco Borba, PR), Angatuba (in Angatuba, SP) plants or to form buffer stocks which can be at different locations according to strategic interest. In the event of need for additional manufacturing (some special finishing), the material in question will be dispatched by the final manufacturer to the end client or to inventory and thereafter to the end client.

Transportation may be via road or rail (for closer destinations and South America) or multi- modal. In 2009, Klabin opened a commercial office in the United States with a view to improving service to clients in that region and to support sales growth.

CONVERSION

(i) Corrugated paperboard boxes and sheets

The sale of the Company’s products both to the domestic and export markets are the responsibility of a proprietary team of salespersons. Commercial offices are located in São Paulo (SP) and in Lages (SC).

The sales of paper packaging (boxes, sheets, corrugated paperboard accessories) take place at the head office in the city of São Paulo (SP). The latter enjoys the support of regional sales offices with nationwide coverage, its own salespersons and commercial representatives. This structure allows Klabin to operate in this highly competitive segment.

Sales almost in their entirety go to the domestic market throughout Brazil and distributed from eight packaging plants in seven states: São Leopoldo (RS), Itajaí (SC), Piracicaba, Jundiaí - Distrito Industrial e Jundiaí - Tijuco Preto (SP), Rio de Janeiro (RJ), Betim (MG), Feira de Santana (BA) and Goiana (PE).

Logistics for supplying the domestic market is largely in the form of overland transportation (road).

(ii) Industrial bags

The distribution of industrial bags is conducted out of the two industrial plants located in Brazil in the cities of Lages (SC) and Goiana (PE), via road throughout Brazil and to some neighboring countries. The Company uses sea transportation to export to other countries in Latin America, Central America, Caribbean and the United States out of the ports of Itajaí and São Francisco,

Page 103 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

both located in the state of Santa Catarina.

The Company serves the Argentine market out of its industrial unit in Pilar, close to Buenos Aires.

c) Characteristics of the chosen market: i) participation in each one of the markets; ii) competitive conditions in the markets

FORESTRY

Klabin sells logs to be made into products for several segments, such as: frames, furniture, packaging, panels and plywood, among others. Products are largely sold to the American, European and Brazilian markets.

Sales are the responsibility of a proprietary sales team based in the states of Paraná and Santa Catarina.

PULP

As the sole producer of long fiber and fluff pulp in Brazil, the Company’s principal aim is the sale of these products to the domestic market, the focus being on infant and geriatric diapers, sanitary pads and producers of nonwovens. The long fiber and fluff market in Brazil is estimated at approximately 400,000 tons. However, long fiber and fluff pulps are also exported to more than 20 countries, in this way leveraging global growth in the market for infant and geriatric diapers.

The world market for short fiber pulp is about 33 million tons and the product is notably sustainable for sanitary requirements (toilet paper, paper towels, napkins), newsprint and writing papers (books, commercial printing, catalogs) and special papers.

PAPER

Kraftliner and white top liner customers both in the domestic and export markets are largely manufacturers of corrugated paperboard boxes. The Company’s clients are suppliers of boxes to several segments, most notably: food products, chemicals and derivatives, fruit and flower growing, poultry farming, beverages, tobacco, metallurgy, fragrances and cosmetics among others.

A large share of Latin-American overseas clients concentrates in the fruit market, notably in Argentina, Chile and Ecuador, the latter being one of the largest banana exporters in the world. The Company’s strategy to focus on these markets reflects that food products, notably fruit, are packaged in papers with no heavy metals, permitting direct contact with food stuffs – a great competitive advantage Klabin enjoys.

The Company has been increasing its exposure to the domestic market using as its main competitive advantage, the offer of products certified for direct contact with food as well as FSC

Page 104 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

certified products.

The Company’s coated board output provides the raw material for carton board packaging for consumer goods of the most varied segments such as food (in natura or processed: dried, fatty, frozen and chilled); electronic and electrical products; utensils in general; personal care and cleansing products; footwear; canned and bottled beverages, parts and equipment; articles of apparel etc.

According to the Brazilian Tree Industry (IBÁ- formerly BRACELPA), the Brazilian coated board market, excluding liquid packaging board, was 586 thousand tons 2020, 542 thousand tons in 2019 and 545 thousand tons in 2018.

CONVERSION

(i) Corrugated Paperboard Boxes and Sheets

Customers for corrugated paperboard operate in all kinds of industrial segments, some of which include: food products, chemicals and derivatives, fruits, flowers, poultry, beverages, tobacco, metallurgy, fragrances and cosmetics, and other. Domestic sales of corrugated paperboard are also driven by meat, poultry, fruit, tobacco and other exporters.

According to information released by the Brazilian Paper Packaging Association (Empapel), formerly the Brazilian Corrugated Paperboard Association (ABPO), shipments of corrugated paperboard boxes and sheets in 2020 were 3.815 million tons, up 5.5% from 2019’s 3.616 million tons. In 2018, shipments of boxes and accessories were 3.546 million tons, up 1.1% from 2017’s 3.507 million tons.

(ii) Industrial bags

The Company operates in several segments, out of which civil construction (cement, lye and caulk) represents approximately 70% of sales by volume. Other segments served include seeds, chemicals, food products, animal feed and minerals.

d) Seasonal effects

FORESTRY

Sales in the forestry segment are subject to no significant seasonality.

PULP

Demand for the pulp output usually trends up as the summer vacations end in the Northern Hemisphere, as well as during the Holidays season.

PAPER

Kraftliner and white top liner exports to meet the demand from customers in South America is Page 105 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

greatest during the fruit harvest period, beginning around August and lasting through March of the following year. There are basically no seasonal fluctuations for banana exporters. In both markets the third quarter is most active, with a decrease in December and January, with the exception of clients in the fruit growing business. In Europe, the market drops sharply in the summer, beginning in June and proceeding through until August.

Coated board sales are associated with consumer goods of various types, tending to mitigate demand variations over the course of the year, but remain subject to a degree of seasonality. A typical year (ex- economic events and disasters) sees brisker demand in the second half, when consumption is driven by the Holidays seasons

CONVERSION

(i) Corrugated paperboard boxes and sheets

Corrugated paperboard sales are related to consumer goods production, the segment reporting stronger movement in the second half of the year in the run-up to the year-end holiday period. The packaging market is also influenced indirectly by exports of tobacco, fruits, meats and poultry, etc.

(ii) Industrial bags

Cement consumption decreases in the rainy season. In Brazil, the Company’s sales of industrial bags are weakest in January and February. On the other hand, the seed segment shows strongest demand in the months of March and April when seed harvest is at its peak.

e) Principal inputs and raw materials

i) description of the relations with suppliers, including whether they are subject to governmental control or regulations, indicating authorities bodies and the respective applicable law;

Klabin’s relationship with its suppliers is based on a policy of respect and trust. In order to make the process more transparent, the commercial relations are undertaken by the procurement areas focused on: developing new sources of national and international supplies; coordinating the process for electronic purchasing with qualified suppliers; encouraging small and middle market companies to take a greater participation in the mix of suppliers; and to capture synergies with the production sales and logistics areas, among others.

In 2011, the Company set up a Supply Chain Division in the light of its territorial coverage and large number of agreements with suppliers in different locations, the structure responsible for the management and negotiation of the acquisition of products and services necessary for the operations at each unit.

All contracts executed with suppliers are established through a process of ratification in which aspects such as occupational safety, health, legal, commercial, technical, environmental responsibility and financial are assessed. The agreements also carry specific work protection clauses. Among these are aspects such as the prohibition of child and forced labor, child prostitution on the highways and protection of the environment.

Page 106 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

Suppliers are required to substantiate their technical expertise in meeting the Company’s demands in terms of deadlines and volume; supplying when so requested a sample/lot of their products for evaluation; adopting socially responsible practices- such as guaranteeing basic benefits to their employees, providing a safe productive and participative work environment and not using child labor – and demonstrating standards of environmental responsibility. Suppliers should also collaborate in the strengthening of the supply chain, incentivizing free competition and technical visits and permitting technical visits for evaluating the installations, equipment, production processes, etc.

There is no policy to give special preference to purchases from local suppliers. However, the Company endeavors to stimulate greater participation on the part of small and middle market companies. The area also focuses on aspects such as: adopting a process of electronic purchases with qualified suppliers; negotiating corporate agreements and contracts for the supply of raw materials and services, and coordinating and executing the import processes, among others.

The relationship between the Company and its suppliers is generally of a medium and long-term nature. The majority of inputs acquired by the Company carry variable pricing, reflecting the equilibrium between supply and demand in the sectors. Significant increases in demand or sudden restrictions on supply can drive up international prices or vice versa.

Service providers are subject to inspection and audit procedures for substantiating their strict compliance with labor laws and payment of social contributions and labor charges. The inspections include viewing labor documentation and inspecting operations to ensure that working conditions are decent and that there is no evidence of child labor. These procedures guarantee the conditions established for parties contracted by the Company, with employees physically present in the units of the company or any other site which Klabin may determine.

Monitoring of all documentation with respect to the labor relations area may take place at the supplier’s premises with a view to more detailed analysis. Should eventual irregularities be found, the contracting area and the supplies sector are responsible for adopting measures, which include communicating in writing to the supplier on the suspension of payments until the aspects deemed as faults are remedied; and acknowledgment that any reoccurrence shall result in the disqualification as a supplier to the Company. The disqualified company may only be re- contracted with the elapse of two years from the date of contractual rescission. In the event of further irregularities during the period of a new agreement, the supplier will be definitively disqualified.

The relationship with the electric energy concession holders and distributors, and suppliers of gas and fuel oil is subject to the regulations of government authorities (ANEEL, ANP) which set prices and contracted requirements.

ii) any dependence on a few suppliers

Electric energy distribution and transmission through the Brazilian Electricity System is restricted to the companies with a Federal concession in the states where they operate – an example being COPEL (Companhia Paranaense de Energia) in the state of Paraná – and must be used by all consumers nationwide. However, since all Klabin’s productive units are part of the Free Energy Market, they are free to negotiate and purchase all of their electric energy requirements directly with and from generators or traders. This is managed on a matrix basis at the Company. Some dependence on a few suppliers or a concentrated number of suppliers may Page 107 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

also be found in the case of fuel oil or the manufacturers of some products.

iii) any price volatility

Services provided to the Company are covered by medium term agreements and are subject to limited oscillation in values. Price readjustments are made through the medium of periodic negotiations based on agreement and inflation. However, the prices of inputs are subject to greater volatility and determined by the equilibrium between supply and demand in the markets. As a rule, price formation for these products are influenced by GDP, inflation, level of economic activity in Brazil and the world, variation in interest rates, tax burden and the floating of the Real relative to other currencies, as well as natural phenomena which may impact the supply side. The costs of electric power are readjusted periodically following a tariff revision by the concessionaires and eventual charges approved by the government.

7.4 Important clients (responsible for more than 10% of the Company’s total net revenue): a) Total amount of revenue from the client; and b) Operational segments affected by revenues from the client

On December 31, 2020 one client in the paper segment was responsible for approximately 12% of net revenues, equivalent to BRL 1.4 billion.

On December 31, 2019, one client in the paper segment was responsible for approximately 13% of the net revenue, corresponding to BRL 1.3 billion.

On December 31, 2018, two clients were responsible for approximately 33% of the net revenue, corresponding to BRL 3.3 billion, being 11% (BRL I .08 billion) in the paper segment and 22% (BRL 2.18 billion) in the pulp segment.

The remainder of the Company’s customer base is dispersed such that none of the remaining clients, individually, have a significant share (more than 10%) of the net income from the Company’s sales.

Certification

Klabin was the first Brazilian company to be recognized by the Rainforest Alliance as "Creator of Sustainable Development Tendencies", in the light of the way it manages its forests. The Company’s sustainable management was also instrumental in it becoming the first in the Americas in the pulp and paper sector to receive FSC (Forest Stewardship Council) certification in 1998 for its forests in the state of Paraná. In 2004, the forest plantations in Santa Catarina were also awarded the green seal.

The FSC seal recognizes that the entire packaging production chain from forestry management to paper manufacture and conversion take place in an environmentally correct, social fair and economically viable manner. Certification also guarantees traceability of the raw material along the entire production chain.

Focusing on the multiple and rational use of its forests, Klabin also encourages activities for the sustainable use of their rich natural resources. In 1999, Klabin was the first company in the world to have non-wood forest products certified in the light of its management of medicinal plants and chain of custody phytotherapeutic and phytocosmetic products produced as part of its Phytotherapy Program.

At all units, environmental performance indicators show advances year after year with the implementation of standardized procedures, as in the case of selective trash collection,

Page 111 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

separation of waste, company organization, among others. All employees involved are trained to act preventively and in the control and attendance of environmental emergencies.

The company also has certifications for ISO 22.000, ISO 9001, OHSAS 18.000 norms and from the Isega Institute of Germany.

Biodiversity

The conservation of the biodiversity is one of Klabin’s environmentally responsible practices enshrined in its Sustainability Policy. The results achieved in this field reflect the adoption of the forestry management system in a mosaic formation, interspersing indigenous vegetation with pine and eucalyptus plantations to form ecological corridors. This allows suitable habitats to be maintained for fauna and flora and ensure the maintenance of water-quality and the equilibrium of the ecosystem.

It is thanks to these practices that Klabin was selected for inclusion in the book Exemplary Case Studies in Sustainable Forest Management in Latin America and the Caribbean, published by the United Nations Organization for the Food and Agriculture Organization (FAO). The document contains 35 case studies in 14 different countries from these regions. Klabin is the only Brazilian company highlighted due to the multiuse of wood and non-wood forestry resources. Correct environmental practices together with suitable procedures in the management of the landscape ensures the exploitation of the productive potential of the Company’s forests with the protection of their natural resources.

Monitoring

Since the beginning of its activities, Klabin has been working to identify and monitor the biodiversity of its forests, based on the identification of species either rare or threatened with extinction on lists such as those of the International Union for the Conservation of Nature (IUCN) and the Brazilian Institute of the Environment and Renewable Natural Resources (IBAMA). The work of mapping and preserving the ecosystems is based on the regulations of environmental bodies and is executed in partnership with research institutes. It covers different species of animals (mammals, birds, reptiles, amphibians, insects, among others) and studied for understanding the dynamic and relations with their habitats. The results of these analyses permit the use of sustainable management models.

In parallel with these monitoring activities, different procedures and programs are adopted to protect these areas, such as:

 Non-performance of activities in adjacent production areas that would impact the preserved areas (e.g.: avoiding erosion and silting of preserved areas, not using river banks and not felling planted trees).  Controlled use of chemicals preventing risks to protected areas.

In December 2020, the Company had 564 thousand hectares of land, of which 266 thousand hectares were planted forests of pine and eucalyptus, 243 thousand hectares of preserved native forests, 17 thousand hectares of unplanted areas, and 37 thousand hectares divided into roads, dividers, structures among others.

Page 112 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

All planted wood is subject to a process of mechanized harvesting, thus ensuring better productivity, reliability and safety, with lower losses and reduced cost.

With the operational startup at the Puma Unit in 2016, Klabin handled 14 million tons that year, between wood logs which are sold to saw mills, pine and eucalyptus chips for the manufacture of pulp and paper, as well as waste for the production of energy at Klabin’s factories.

The Company is aware of the importance of maintaining the biodiversity for preservation of natural life, and adopts strategic policies to monitor and preserve the various species of plants and animals in its indigenous forests. In this context, a Natural Heritage Private Reserve (RPPN) is installed at Fazenda Monte Alegre in Telêmaco Borba (PR) with an area of 3,852 hectares and in the state of Santa Catarina, the Serra da Farofa Complex with an area of 4,920 hectares.

Through continual monitoring, diagnoses are undertaken for verifying the quantity and quality of populations, threatened species and habitats as well as tracking of emissions and corrective actions in the event of any divergence. An annual management plan is prepared for the forestry units to include biodiversity data based on the surveys and aimed at reducing the negative impacts and expanding the positive ones, as well as the restoration of areas for improving environmental conditions of the indigenous forest reserves, enhancing resources for the fauna and flora. Among the procedures adopted for example is the avoidance of any activity of impact in productive areas adjacent to preserved areas.

c) Dependence on patents, trademarks, licenses, concessions, franchises, significant royalty agreements for the development of its activities.

The Company is not dependent on its trademarks, patents, licenses, concessions, franchises and royalty agreements.

For additional information on the Company’s trademarks and patents, see item 9.l(b).

The Company exports to more than 80 countries and is subject to regulations in these jurisdictions. The authorities responsible for the countries to which the Company exports its products may revise the prevailing rules and regulations and alter the terms and conditions of the licenses awarded to the Company and/or its subsidiaries to which the Company must adhere. The adherence to these regulations may require that the Company incur operational expenses and additional capital which may be significant. To ensure compliance with the existing laws, rules and regulations, the Company should periodically replace, repair or update the installations, existing equipment or material, which may mean the Company incurring additional capital.

In addition, Brazilian exporters are being increasingly affected by measures on the part of importing countries to protect local producers. The competitive nature of Brazilian companies has meant some countries introducing commercial barriers to limit market access of Brazilian companies to their markets or even to subsidize local producers. Some countries impose import quotas on products from Brazil and delays in allocating such quotas or changes in the legislation or policies related to these quotas may adversely affect the Company’s exports.

Klabin’s industrial bags factory in Argentina is registered and regulated by organs covering the environment, labor laws, tax regime and labor unions and has been complying with all legal requirements, there being no barriers preventing normal operations.

7.9. Other relevant information:

Management of sustainability

Klabin maintains a structure dedicated to sustainability management led by a Corporate Unit made up of four areas: Sustainability Governance, Environmental Responsibility, Ecological Park and Social Responsibility.

In addition, there is a Sustainability Management Committee made up of five managers of strategic areas covering ESG themes. Its mission is the pre-analysis of sustainability-related themes for subsequent submission and validation by the Permanent Sustainability Commission. The latter is made up of officers from five areas and a responsible technician all with the role of establishing guidelines and assessing the need for investments and prioritizing initiatives, submitting topics for analysis and final approval by the Executive Board.

Recognition in Sustainability

In 2020, Klabin’s sustainability practices were once again recognized domestically and internationally. A highlight has been the Company’s Dow Jones Sustainability Index’s Global and Emerging Market listings. Klabin is the only Brazilian company on the global portfolio. The index evaluates and recognizes world-leaders in ESG (environmental, social and governance) performance.

In addition, our sustainability-oriented practices are recognized by the Company’s long-standing presence in indices and rankings such as B3’s Corporate Sustainability Index – ISE (since 2014), which lists the shares of companies that stand out for their high level of commitment to business and national sustainability, and its 90.3% environmental performance score according to the 2019 Environmental Paper Company Index (EPCI) – held biannually by the WWF, for the fourth consecutive year.

Klabin is a component of the CDP’s A-List for water and forest management programs, with leading performance in the climate change program. This achievement places Klabin among the companies that the institution highlights as leaders of the transition to the new sustainable economy. The initiative analyzes and recognizes efforts of companies around the world to manage the environmental impacts of their activities. In 2020, the evaluation methodology involved 515 with more than US$ 106 trillion in total assets.

The Company also placed high for the third consecutive time in the Spott Timber & Pulp rankings, which evaluate the soundness and transparency of sustainability management on the part of 50 wood and pulp producers worldwide. The Company placed first in the global ranking of paper and pulp companies.

Also in 2020, Klabin maintained its status as a Best Emerging Markets Performer according to Vigeo Eiris, a global provider of environmental, social and governance research and services, which evaluates the performance of emerging market companies on several criteria broken down into six areas: environment, human rights, human resources, community outreach, business behavior, and corporate governance.

platform, which focuses on local development, education and culture, and aims to create a positive socio-environmental impact and leverage the economy of the communities in which it operates.

In 2020, the Company invested more than BRL 24.9 million i socio-environmental and cultural programs such as:

• community projects and actions in the areas of education management, public management, regional planning, and sustainable development agenda preparation;

• skills-building and income generation actions on behalf of small farmers and communities;

• environmental monitoring, conservation and education projects;

• cultural support and popularization initiatives.

KLABIN EDUCAÇÃO

Klabin’s actions on the education front include initiatives to foster education, sports and citizenship. The projects focus on training for teachers and students at all levels (children’s, basic, middle, trade, and off-shift) and improving school infrastructure. Some illustrative projects include Semeando Educação and the actions of Terra Viva Associação de Voluntários da Klabin, which stimulate volunteering among Klabin’s employees.

Klabin Semeando Educação Project

The program provides consulting services for principals, educators and teachers in 31 public state schools, sharing methods, best practices and tools to improve school management indicators, including leadership training and increased participation of the school community. It takes place in the municipalities of Telêmaco Borba, Ortigueira and Imbaú, in the state of Paraná, and has the support of consultancy firm Falconi and Klabin employees acting as facilitators. The program was created in 2017 and has since provided training to more than 140 school managers, benefitting over 11 thousand students.

After producing good results in the state public education network, the program was extended to municipal schools as well. In its new phase, the initiative is expected to serve 11 thousand students aged zero to 10 years old, and a thousand teachers from 65 schools in the urban and rural areas of the three municipalities.

Terra Viva

Terra Viva Associação de Voluntários da Klabin is a non-profit organization formed in 2003 that has since organized and promoted citizenship and solidary actions supported by employees and their family members. Projects may be one-off, such as rallies for winter clothing, food, milk, blood donations, associated with celebratory dates, or educational, as illustrated by guidance on first-job seeking, technical and creativity lessons such as guitar, languages, information technology and more. The publics served go from socially vulnerable or special- needs children and youths to the elderly.

KLABIN FOR LOCAL DEVELOPMENT

Klabin believes in the economic, social and cultural empowerment of communities as a means towards the development of the locations where it operates. Its social investment initiatives strengthen each region’s skills, knowledge and potential. Highlights include the Community Development Forums and the Legal Forests and Planning Sustainable Properties (Social Forests) as well as Meliponiculture and Bee Keeping.

Community Forums

The Community Development Forum project began in 2015 in the cities of Correia Pinto and Otacílio Costa, state of Santa Catarina. Since then, the Forum Program has been expanded to new areas where Klabin has operations.

In 2019, we set up the Local Development Forum of Angatuba (SP), continued our activities in Goiana (PE) as well as holding meetings in Otacílio Costa and Correia Pinto (SC). The proposal is to involve a range of different actors from organized civil society, among them Klabin, so that all can work together for designing a new land management model by discussing solutions for local issues. The initiative has been fined tuned using the Social Progress Index (SPI), a methodology for measuring quality of life in a given region, independently of economic development. See more on the indicators in the website www.progressosocial.org.br.

Legal Forests

This initiative is a partnership with the Association for Preservation of the Environment and Life (Apremavi) and involves planning of rural property, conservation, environmental education and forest development in the states of Paraná and Santa Catarina. Small and midsized property owners receive guidance on the most efficient, profitable and environmentally-friendly ways to operate. Producers take courses, conduct community support actions, make visits to exchange knowledge and receive free native seedlings. The program also encourages silviculture with forest plantations, both pine and eucalyptus as well as indigenous species; the enriching of secondary forests; the restoration of riparian forests, supporting the conservation of water resources; organic farming and ecotourism.

Social Forests - Planning Sustainable Properties

The Social Forests project helps small rural producers in 10 municipalities in the state of Paraná to obtain Rural Environmental Registration and in the sustainable planning of the use of their properties. The initiative also encourages family farming, prevents rural depopulation, the development of the regional production and consumption chain and fosters entrepreneurship. The project is run in partnership with the Micro and Small Company Support Service (Sebrae), the international The Nature Conservancy (TNC) organization and Aprernavi. The Social Forest project has already helped more than 500 rural property owners over its five-year existence.

Bee Keeping and Meliponiculture

Through this program, which began in 2005, Klabin grants use of its forests to the families of small and medium sized farmers for beekeeping. In addition to increasing household income,

Page 120 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

the program benefits biodiversity and ecosystem conservation as the bees pollinate the plants, improving the productivity of other cultures. Since the outset of the Program, a total of 178.7 tons of honey has been produced and sold.

Regional Development Guidelines

Supported on the economic, social, environmental and educational pillars, the Regional Development Guidelines (DDR) are designed as guidance of the 12 municipalities affected by the Puma Unit’s operations in Paraná for the improvement of indicators and to instruct the best use of resources.

Strategic government plans and other initiatives supporting municipal government management, particularly in education –still at a development stage – are some of the products aimed at sustainable regional development being proposed by Klabin. The initiative began in 2017.

Guidelines include appreciation of family farming and regional tourism, water and sanitation provision actions, health, construction of housing and road improvements as well as education. Management of the DDRs is conducted on a collegiate basis through the combined efforts of the municipalities, optimizing demands on the basis of an overview of the entire territory.

KLABIN AMBIENTAL

On the Environmental Education front, Klabin runs projects for teachers and students in local communities for raising ecological awareness, promoting respect for the environment and for the conservation of the biodiversity. Notable are the Caiubi, Environmental Protectors, Growing Up, Ecological Park projects and the Conservation of the Private Natural Heritage Reserves Program (RPPN).

Caiubi Program

The program trains municipal education teachers in the states of Paraná and Santa Catarina, with the support of municipal governments, institutions and professional partners, to raise ecological awareness and contribute to the formation of citizens aware of their responsibilities to the environment. A total of 442 schools and more than 1,200 teachers and nearly 160 thousand students have all benefited from this program since 2007.

Environmental Protectors

Theoretical and practical training provided to elementary school students on nature preservation, environmental law, aspects of the local wildlife and plant life, first aid, civics, morals and ethics as a means to train environmental education multipliers. Held by the Santa Catarina State Environmental Policy, the program has had Klabin’s support since 2005. It has since benefitted more than 600 teenagers 11-14 years old in several municipalities where the company operates in Santa Catarina.

Força Verde Mirim

Page 121 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

The project began in 2014 in Telêrnaco Borba (PR) and fosters environmental education and initiatives for raising the awareness on the environment and on the importance of conserving the natural riches. Since its inception, the program has been used to train 346 fourth and fifth elementary grade students in municipal schools.

Growing Up Project

We provide continued education for direct and indirect employees on matters related to the environment, health, household management, quality of life and professional growth, among others. The Project is being run in Santa Catarina and Paraná, and serves 4 thousand and 6,304 people respectively, including own and third-party employees in various positions.

Ecological Park

Established in the 1980s in Fazenda Monte Alegre (PR), the Klabin Ecological Park has an area of 11 thousand hectares, 71% of which are natural forests. Activities include biodiversity conservation, wildlife rehabilitation, protection of threatened species, scientific research and support to environmental education projects.

CULTURAL KLABIN

Klabin’s initiatives to foster cultural development through artistic expression include those of the Vera Lafer Cultural Center, such as the Singing Girls, the Right Step, Our Digital Language and the Decolar Project, together with the projects under the auspices of the Ema and Eva Klabin foundations.

Klabin’s Singing Girls

Created in 2004 at the Monte Alegre Unit and extended to the Puma Unit in 2017, both in the state of Paraná, Klabin’s Singing Girls is a group made up of the daughters of employees and young girls from the Telêmaco Borba and Ortigueira community aged 7 and upwards. The project offers choral singing and teaches the basic principles of musical theory, rhythm and vocal techniques.

Right Step

Formed in August 2008 at the Monte Alegre Unit in partnership with Studio 3 Cia. de Dança and later extended to the Puma Unit in 2017, the program offers a program of contemporary dance and capoeira for six-year old’s and upwards - children and adolescents of the Company’s employees as well as siblings of residents in the Telêmaco Borba and Ortigueira communities.

Our Digital Language

In partnership with the Jaborandi Institute, the project seeks to improve the oral and written communication skills of youngsters between 13 and 18, children of employees and residents of Page 122 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

the Telêmaco Borba (PR) community. It employs new information and communication technology and uses technology for introducing themes such as identity, sexuality, the environment, citizenship, narcotics, among others.

Initiatives in combat of COVID- 19

Since the beginning of the pandemic, the Company has actively worked on prevention measures to control the spread of Coronavirus (COVID-19) among its employees and the community. Besides the reinforcement of the hygiene protocol and the propagation of pertinent information in its official communication channels, Klabin remains aligned with the guidelines of the World Health Organization (WHO), adopting several measures, including the cancellation of travels, implementation of medical and monitoring committees in all of its units, flexibilization of the routine and management of remote work, adoption of alternate shift system and individualized food service.

Additionally, and aiming to extend these prevention measures, on March 23 the Company announced the temporary demobilization process of professionals involved in the civil construction and assembly works of Project Puma II which had, by the time, approximately 4,500 professionals on site. In mid-April, the Company began the gradual reintegration of some of these professionals, most of them residents of the state of Paraná. By reinforcing sanitary protocols and implementing several measures to tighten up hygiene conditions, the full reestablishment of the works and their professionals is still subject to evaluation in the coming weeks of COVID-19's epidemiological scenario, especially in the regions near the site.

All these initiatives, which aim to ensure the safety of its employees and prioritize the health and well-being of all, ensure also the maintenance of the operational activities of Klabin, the largest producer and exporter of packaging paper in the country, to ensure the production of containers that fill, protect, store and transport items of prime necessity, important for the population, especially in the segments of industrialized and fresh food (milk, protein, wheat flour, fruit, frozen and other kinds); of personal and medical hygiene (baby and geriatric diapers, sanitary pads for hospital beds, paper towels and toilet paper); and cleansing products (detergents, sanitizers, alcohol, among others). It is worth noting that Klabin has approximately 80% of its total production directed to the food, hygiene and cleansing segments, considered of prime necessity. It is also the only producer of fluff pulp in Brazil, a primary material for the production of disposable diapers.

From March to December 2020, we donated over BRL 15 million to mitigate the impacts of Covid-19. The funds were allocated to relief for more than 30 municipalities in 10 states where Klabin is present, showing, as goes the campaign’s motto, that “every attitude counts”. Actions took place on three fronts: health, social work, and income generation for workers in vulnerable industries.

Some noteworthy initiatives include:

 an innovation developed at our technology center, where we produced hand sanitizing gel with micro fibrillated cellulose (MFC), a wood derivative that replaces carbo-mer, a fossil input that is not produced in Brazil. Four tons of hand sanitizer were produced and packaged in exclusive containers made from Klabin kraft paper for delivery to healthcare institutions;  In partnership with the Government of the State of Paraná and the City Hall of Telêmaco Borba, Klabin began the civil construction retrofitting for the installation of ICU beds and infirmary beds for a Campaign Hospital in Paraná, which will provide exclusive are to Coronavirus patients from seven municipalities in the region;  Participation of the Saving Lives Campaign, together with the Brazilian Development Bank Page 123 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

(BNDES), for delivery of supplies and equipment such as masks, gloves and lung ventilators to philanthropic hospitals and charitable hospitals.  Klabin is part of the Federal Government consortium together with other companies to manufacture 6.5 thousand Magnamed ventilators, which will significantly increase domestic availability of the device;  Donation of approximately 100,000 hospital and hygiene items and more than 400,000 corrugated packages for shipment of food and hygiene products to hospitals, entities, institutions and communities throughout Brazil.  Donations to the 'Pimp My Carroça' organization, which will generate minimum income for recyclables scavengers nationwide;  Donation of 4 tons of paper to produce disposable cups for major hospitals.

Through measures to prevent and fight the effects of the COVID-19 pandemic, Klabin reinforces its commitment to the well-being of its teams, their families and society at large. Finally, the Company emphasizes the commitment of its employees, especially those who are in forestry and manufacturing operations, spearheading production of key items for the country’s basic supply chain

9.2. Additional information that the Company may deem relevant: Permanent Preservation Areas The Company maintains and works to improve the quality of the environment in its permanent preservation areas. Private areas with their boundaries provided by force of law help maintain biodiversity, and the quality of the air, water and soil in a global manner. Preserved forests contribute to environmental balance and the sustainability of the forest business. As of December 31, 2020 the Company had 243 thousand hectares of permanent preservation areas.

Insurance To protect its operational risks, assets and responsibilities, the Company maintains insurance coverage for a variety of events capable of affecting its equity and operations.

According to best market practices, the Company maintains insurance policies for operational risk, including lost profits and other forms of coverage for property damage, involving all manufacturing, administrative and storage facilities.

The Company has other insurance policies in place, with coverage including general liability, D&O liability, environmental liability, domestic and international freight, and forests, as well as engineering risks, liability and construction works insurance to support expansions and//or new sites built to join the Company’s operations. The sum of all maximum insurance indemnities was BRL 6.1 billion as of December 31, 2020.

Management therefore understands that its insurance framework provides appropriate coverage for the Company’s operational continuity.

10.1. Overall financial and equity conditions a) Overall financial and equity conditions Management understands that the Company has the financial and equity conditions to maintain and develop its operations. Revenues come from domestic and foreign market sales of packaging paper and board, short- fiber cellulose, long-fiber cellulose, fluff pulp, cardboard boxes, paper bags, and timber for sawmills. The Executive Board’s financial strategy maintains a high cash position and a lengthy debt profile.

Ratios 12/31/2020 12/31/2019 12/31/2018 Current liquidity 2.98 4.40 2.93

General liquidity 0.41 0.57 0.54

Net debt-to-adjusted EBITDA 4.21 3.30 3.10

Adjusted EBITDA-to-Total assets 13.33% 12.46% 13.58%

Net Earnings-to-Shareholders’ Equity -62.71% 11.82% 2.97%

In the three fiscal years shown above, current assets exceeded current liabilities by BRL 7.2 billion, BRL 10.6 billion and BRL 7.2 billion in 2020, 2019 and 2018 respectively, corresponding to current liquidity ratios of 2.98 as at yearend 2020, 4.40 as at yearend 2019 and 2.93 as at yearend 2018. General liquidity, too, was positive in the three fiscal years at hand, at 0.41, 0.57 and 0.54, respectively. In fiscal year 2019, the Company began a new expansion project (Puma II) for the construction of two new paper mills. Expected investment is BRL 9.1 billion, with effective outlays of BRL 1.3 billion in 2019 and BRL 4.0 billion in 2020, which affected the Company’s net debt. In addition, indebtedness in fiscal year 2020 was sharply affected by the 29% depreciation of the Brazilian real versus the US Dollar, as the Company had foreign currency-denominated debt of approximately USD 4.0 billion as at yearend 2020. Adjusted EBITDA-to-Total assets trends up in the fiscal years shown, due to the stabilization of operations at the pulp mill (Puma I) commissioned in 2016, to increased demand for staple products, and to currency depreciation effects due to the pandemic. On the other hand, the ratio was down in 2019 due to the beginning of work on Puma II, with the outlay of BRL 1.3 to purchase assets without offsetting cash generation. In 2020 the outlay was BRL 4.0 billion, for a total outlay of BRL 5.3 billion as at yearend 2020. The two paper mills are slated for commissioning in July 2021 and July 2023, respectively. The Company chooses Adjusted EBITDA over Net Earnings because the latter excludes exchange-rate effects on financial liabilities and the change in the fair value of biological assets, as well as of depreciation and amortization, all of which have a relevant presence in the income statement, with impact on net income. b) Capital structure The Company’s third-party capital includes financing secured with the financial and capital markets, largely to maintain fixed assets, make new investments, and lengthen its debt profile. Own capital is made up of the Company’s shares, representing shareholders’ equity.

Page 164 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

Based on the consolidated financial statements of December 31, 2020, the Company has 12% own capital over total assets and 88% third-party capital over total assets. There are no cases of redemption of the Company’s shares except as provided in the Corporations Law.

c) Payment capacity vis-à-vis financial obligations Given the Company’s debt profile, cash flow and liquidity position it has sufficient liquidity and capital to cover its investments, expenses, debt and other amounts payable over the coming years, with a cash position sufficient to amortize 59 months of its debt. In 2020, the Company undertook liability management, reducing its short-term debt from 5% as at yearend 2019 to 3% as at yearend 2020, in addition to increasing the average debt maturity from 96 months as at yearend 2019 to 116 months as at yearend 2020. If a need arises to secure financing for investment in new projects and acquisitions, the Company believes that it has the capacity to do so. The Company’s cash as of December 31, 2020 was sufficient to amortize approximately 81 months of its upcoming financial debt. As indicated in the announcement to the market of March 19, 2020, although Klabin faces highly volatile financial markets, it has a robust cash position, a lengthy debt profile, and 100%¨financing for the Puma II Project. d) Sources of financing used for working capital and investment in non-current assets In addition to cash from its own operations and those of its subsidiaries, the Company raises funds in a variety of ways in the domestic and international markets, including bilateral, syndicated operations, with financing agencies and the capital markets to finance its working capital and investment in non-current assets. For major projects, the Company relies on financing facilities with BNDES and multinational import agencies, or the issue of shares and convertible or non-convertible securities.

e) Sources of financing for working capital and investment in non-current assets that the Company intends to use to cover liquidity shortfalls The Company has not faced a situation of liquidity deficiency. In addition to the current cash position, Klabin's liquidity position comprises a revolving credit facility of US $ 500 million, with a five-year term of availability and a financial cost of 0.4% per year. If the line is withdrawn, the cost of this financing would be Libor + 1.35% per year.

Page 165 of 348

In addition, the Company also has financing lines linked to the execution of the Puma II Project and not yet withdrawn: (i) BID Invest, IFC and JICA, totaling US $ 700 million; (ii) Finnvera, totaling US $ 178 million and (iii) BNDES, totaling BRL 2 billion. With the worsening of the Covid-19 pandemic and the unfolding of this crisis, the Company points out that there may be liquidity difficulties in international markets, disadvantaging new funding at this time. f) Debt levels and debt characteristics

certain ratios in association with income, liquidity or leverage compared to the contracted operations, or that make repayment of the debt immediately due. As the COVID-19 pandemic deepens, the Company underscores that liquidity issues may arise in the international credit markets, hampering access to new debt and financing. However, despite the financial markets’ increased volatility, Klabin’s cash position is robust, its debt profile is extended and funding for the Puma II Project is 100% contracted. Therefore, we see no evidence of liquidity risk for the Company at this point. g) Limits of financing agreements and percentages withdrawn As disclosed in announcements to the market of October 31 and November 6, 2019, the Company has the following financing agreements in place on which it has not yet drawn, associated with execution of the Puma II Project.

Net Revenue from Sales

Net operating revenue from sales in FY 2020 was BRL 11.9 billion, up 16% from 2019. Sales volume (ex- wood) was 3,554 thousand tons, up 7% YoY.

The main impacts on net sales revenues in 2020 compared with 2019 were:

(i) 15% increase in sales revenues in the Paper segment, from BRL 3.5 billion in 2019 to BRL 4.2 billion in 2020, and 21% increase in sales revenues in the Conversion segment, from BRL 3 billion in 2019 to BRL 3.6 billion in 2020, influenced by the strong presence in essential goods markets and e-commerce, which experienced strong demand during the pandemic, and the excellent operational performance of its units.

(ii) 11% increase in sales revenues in the Pulp Segment, from BRL 3.5 billion in 2019 to BRL 3.9 billion in 2020, with significant influence from the recovering demand in late 2020 in certain regions, and the US Dollar’s depreciation comparted to other global currencies, adding to product prices.

(iii) In October 2020, the Company completed acquisition of the assets of International Paper, which were responsible for generating BRL 271 million in additional Revenues in FY 2020.

Page 173 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

(iv) Approximately 45% of the Company’s sales volume is allocated to the international market, where the exchange rate affects prices. In 2020, the average exchange rate was BRL 5.15 to the US Dollar, up 28% from 2019, boosting revenues from sales of export goods.

Variation in the fair value of biological assets

The 2020 variation in the fair value of biological assets is equivalent to a BRL 648 million gain arising from increased productivity and extension of the forestry, in addition lower discount rates in terms of discounted cash flow.

The effects of the change in the fair value of biological assets in 2019 correspond to a BRL 390 million gain, arising from forest expansions and the revised discount rate used in calculations. In addition, the balance experienced a negative impact from the lower market prices of wood, from an average BRL 67/m3 at yearend 2018 to BRL 66/m3 at yearend 2019.

Cost of goods sold

The cost of goods sold in 2020 was BRL 7.9 billion, exceeding the 2019 amount due mainly to the 7% increase in sales volume (ex- wood). I addition, the amount was largely affected by the costs of the scheduled stop of the pulp unit, and lower generation and sale of electric energy. Another contributing factor to the increase is a product mix with a larger share of paper and packaging materials, with higher cost value-added.

The best indicator for cost determination when volumes are not comparable is the analysis of the unit cash cost in BRL/t, which covers sales of all of the Company’s products and includes sales, general and administrative expenses. This indicator was BRL 2.037/t in 2020, up 3% from 2019, ex- the one-time tax credit gain arising from the res judicata court ruling in favor of the Company’s claim to remove the ICMS tax bill from the PIS and Cofins taxable base, which added BRL 620 million in FY 2019, and the gain from the advantageous purchase of International Paper’s assets in Brazil, in the amount of BRL 206 million in 2020.

The minor 3% increase in the unit cash cost BRL /t was feasible due to the dilution of costs arising from the increased sales volume, as well as to increased efficiency at the Tall Oil plant, reducing the fuel and energy consumption over the year. On the other hand in addition to inflation impacts in 2020, the Company experienced an increase in the cost of wood due to the greater average felling radius and increased volume of wood purchased from third parties.

Operating expenses/revenues

(i) Sales

Sales expenses in 2020 were BRL 1.139 billion, up 25% from 2019 and representing 10% of the net sales revenues (versus 9% in 2019). At yearend 2018, Klabin put an early end to the supply arrangement it had with Fibria/Suzano for sales of short-fiber cellulose outside of South America, which Klabin took over in full from August 2019. The agreement was a free on board – Port of Paranaguá operation and the costs, which were previously deducted from the applicable price, have since then been booked in Klabin’s sales expenses line.

(ii) General and administrative

Page 174 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

General and administrative expenses were BRL 718 million in 2020, up 19% from 2019. The increase is due mainly to greater investment in information technology and engineering and design advisory services, in addition to COVID-19-related expenses including donations and services to reinforce the Company’s healthcare protocols.

(iii) Other, net

Other net operating revenues/expenses amounted to BRL 317 million in revenues in 2020, influenced mainly by the BRL 206 million gains in goodwill from the acquisition of International Paper’s assets, and BRL 63 million in connection with an insurance event payment.

Concerning FY 2019, particular notice is due on the effects of the non-recurring gain from the res judicata ruling regarding exclusion of the ICMS tax bill from the PIS and Cofins taxable base, in the amount of BRL 621 million.

Financial results

Financial income in FY 2020 was BRL 383 million, down 63% form 2019’s BRL 1 billion. The decrease was mainly due to the monetary restatement of tax credits associated with the res judicata ruling in favor of the Company’s plea to exclude the ICMS tax bill from the PIS and Cofins taxable base, adding BRL 384 million in 2019. Another effect was the lower income from financial investments because of the reduced cash position and lower market interest rates.

Financial expense 2020 was BRL 3.8 billion, up 67% from 2019’s BRL 2.3 billion. The increase is due to the greater gross debt in the wake of the Company’s liability management process, with costs incurred from the early liquidation of loans and financings, in addition to increased indebtedness and costs from financial instruments (Swaps).

Net foreign exchange variation increased to BRL 3.6 billion in expenses from BRL 410 million in 2019. The increase is due to the 28% depreciation of the US Dollar relative to the Brazilian Real in 2020. The change affects the balance sheet’s foreign currency entries, in particular loans and financings of approximately USD 4 billion, and has no net impact on cash as US Dollar- denominated export transactions exceed US Dollar-denominated obligations.

Because of the foregoing, the financial result was BRL 7 billion in expenses in 2020, compared to BRL 1.7 billion in 2019.

Current and deferred income tax and social contribution

In 2020, the Company recognized BRL 1.4 billion in income tax and social contribution, with a positive impact on Net Income arising largely from the BRL 1.8 billion in deferred taxes due to the adoption of the cash regime for foreign exchange rate variations.

In 2019, the Company’s income tax and social contribution bill was BRL 149 million, due to higher taxable income arising from improved operational results.

Net income/loss

The Company’s posted a net loss in FY 2020 of BRL 2.389 billion, due mainly to high financial expenses, influenced by foreign exchange variations given the Brazilian Real’s depreciation Page 175 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

versus the US Dollar.

In addition, concerning net income/loss, the Company underscores BRL 7 million recognized in separate because they concern the Nova Campina (SP) unit, which was listed in the discontinued operations line because of its divestment, planned to take place in the first quarter of 2021.

The Company’s operational cash generation (Adjusted EBITDA ex- non-recurring effects) in 2020 was BRL 4.7 billion, from BRL 3.7 billion in 2019, up 27% YoY.

COMPARISON OF OPERATIONAL RESULTS IN THE FISCAL YEARS ENDING DECEMBER 31, 2019, and 2018

Net revenue from sales

Net operating revenue from sales in FY 2019 was BRL 10.3 billion, up 3% from 2018. Sales volume (ex- wood) was 3,327 thousand tons, up 4% YOY.

The main impacts on net sales revenues in 2019 compared with 2018 were:

(i) 11% increase in sales revenues in the Paper segment, up from BRL 3.2 billion in 2018 to BRL 3.5 billion in 2019, boosted by a 15% increase in revenues from paper exports, up from BRL 1.4 billion to BRL 1.6 billion in 2019, a 12% increase in board exports, taking advantage of its privileged sales position and distinctive product technology, enabling new markets to develop. In addition, with the drop in international kraftliner markets, the Company used its flexibility to allocate sale to the domestic market, increasing net revenues from the domestic market by 7%.

(ii) 5% increase in sales revenues in the Conversion segment, from BRL 2.9 billion in 2018 to BRL 3 billion in 2019, allocating a greater volume of paper to packaging

Page 176 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

production in pursuit of improved returns, taking advantage of the Brazilian economy’s growing demand.

(iii) 5% decrease in sales revenues in the Pulp segment, from BRL 3.7 billion in 2018 to BRL 3.5 billion in 2019, with significant impact from an approximately 26% price retraction over the course of 2019. Operationally, despite the drop in prices, the company increased its production volume in 2019 beyond nominal production capacity, as reflected in the 6% increase in pulp sales by volume compared with FY 2018.

(iv) An approximate 50% of the Company’s sales by volume are allocated to the international market, where the foreign exchange rate affects prices. In 2019 the average BRL-to-USD exchange rate was 3.95, up 8% from 2018, boosting sales revenues in the international market.

Variation in the fair value of biological assets

The 2019 change in the fair value of biological assets corresponds to a BRL 390 million gain from forest growth and the revised discount rate used in calculations. In addition, the balance had negative impact from the lower prices used for valuation purposes, from an average BRL 67/m3 at yearend 2018 to BRL 66/m3 at yearend 2019.

The effect of the change in the fair value of biological assets in 2018 corresponds to a BRL 628 million gain, with positive impact from the higher prices used for valuation, from an average BRL 63/m3 at yearend 2017 to BRL 67/m3 at yearend 2018, in addition to normal forest growth.

Cost of goods sold

The cost of goods sold in 2019 was BRL 7.2 billion, up from 2018 due mainly to the 4% increase in sales volume (ex- wood).

The best indicator for cost determination when volumes are not comparable is the analysis of the unit cash cost in BRL/t, which covers sales of all of the Company’s products and includes sales, general and administrative expenses. This indicator was BRL 1,975/t in 2019, up 5% from 2018, ex- the one-time tax credit gain associated with a court decision that became res judicata in favor of the Company’s claim to exclude ICMS from the PIS and COFINS taxable base, amounting to BRL 620 million. The 5% increase is largely due to inflation on the Company’s costs.

Operating expenses/revenues:

(i) Sales

Sales expenses in 2019 were BRL 910 million, up 19% from 2018, and answering for 9% of the period’s net sales revenue, up 1% from 2018. In addition to the 4% increase in sales volume in 2019, the gain concerns costs incorporated after the expiration of the supply agreement with Fibria/Suzano. Sales were previously made under the free-on-board regime, where the customer is responsible for costs.

Page 177 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

(ii) General and administrative

General and administrative expenses were BRL 601 million in 2019, up 8% from 2018. In addition to the period’s inflation, the increase is explained by topical spending on consultancy and on administrative restructuring, which helped optimize the Company’s corporate structure.

(iii) Other operating, net

In 2019 the company had a non-recurring tax credit gain from a sentence that became res judicata, supporting the Company’s claim to exclude ICMS from the PIS and COFINS taxable base. The BRL 1 billion was recognized as follows BRL 384 million to financial income, and BRL 631 million to Other operating expenses, net.

Financial income

Financial revenue in 2019 was BRL 1 billion, up from 2018’s BRL 495 million. The increase is mainly due to the restatement of tax credits in the light of the sentence that became res judicata, recognizing the Company’s claim to exclude ICMS from the PIS and COFINS taxable base, retroactive to April 2002, resulting in an effect of BRL 384 million.

Financial expenses were BRL 2.3 billion in 2019, up 47% from 2018’s BRL 1.5 billion. The increase is due to the increase in net debt after the Company’s liability management process, with costs involving early settlement of loans and financings, i addition to increased debt and costs arising from financial instruments (swaps).

Net foreign exchange variation was down to an expense of BRL 410 million, vis-à-vis BRL 2 billion in 2018. This was due to the 8% appreciation of the US dollar versus the Brazilian real, whereas in 2018 the US currency appreciated 15% against the domestic one in 2017. This change affects the balance sheet’s foreign-currency balances, mainly loans and financings, and has no net impact on cash, as US Dollar-denominated export transactions exceed US Dollar- denominated obligation payments.

Because of the foregoing, financial income decreased to expenses of BRL 1.7 billion in 2019 versus BRL 3 billion in expenses in 2018.

Current and deferred income tax and social contribution

In 2019 the Company recognized a BRL 149 million Income tax and social contribution expense due to increased taxable income arising from improved operational results.

In 2018, the balance of income tax and social contribution was up BRL 255 million, under sharp impact the deferred foreign exchange variation expense because of the endorsement of the cash regime for FX effects for tax purposes. The decision was reversed in 2019, when the company returned to accrual basis.

Net income

The Company had BRL 715 million in net income in 2019, due to its strong cash operational cash generation.

COMPARISON OF THE MAIN BALANCE SHEET ACCOUNTS ON DECEMBER 31, 2020, AND 2019

CURRENT ASSETS

Cash and cash equivalents and securities

The Company had a balance of BRL 6.6 billion in cash and cash equivalents and securities at yearend 2020, answering for 19% of total assets. The BRL 3.1 billion decrease from yearend 2019 (BRL 9.7 billion) is mainly due to disbursements for the Puma II Project, of approximately BRL 4 billion over the course of 2020, and the early liquidations of Finnvera prepaid exports and export credit notes, in the respective amounts of BRL 6.2 billion and BRL 22 million.

Customer accounts receivable

The balance of customer accounts receivable was BRL 1.8 billion on December 31, 2020, down 3% from December 31, 2019’s BRL 1.9 billion. The decrease is due to the reduced average days’ payment and the effects of drawee risk operations.

Non-recourse receivables discount operations were conducted with specific customers in 2020 in the amount of BRL 2.7 billion, versus BRL 2.4 billion in 2019.

Average days’ payment was 82 days for domestic market sales in 2020, and approximately 112 days for foreign market sales.

Page 179 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

Inventories

On December 31, 2020, the Company had BRL 1.4 billion in inventories, up 6% from yearend 2019, due to the purchase of inputs to meet the high demand for the Company’s products.

ASSETS (LIABILITIES) FROM ASSETS RETAINED FOR DIVESTMENT

Due to the divestment process of the Nova Campina (SP) unit, acquired together with the International Paper assets, assets in the amount of BRL 175 million and liabilities in the amount of BRL 36 million from that unit are recognized separately in the balance sheet, pursuant to the specifically applicable accounting standards.

NON-CURRENT ASSETS

Taxes recoverable

The balance of taxes recoverable in current and non-current assets at yearend 2020 was BRL 1.5 billion, down from the BRL 1.9 billion booked on December 31, 2019. The decrease is mainly due to the use of approximately BRL 500 million in tax credits recognized in 2019 in connection with the res judicata court ruling in favor of the Company’s plea to exclude the ICMS tax bill from the PIS and Cofins taxable base, in the amount of BRL 1 billion.

Deferred income tax and social contribution

The balance of deferred taxes emerges from temporary differences in the netting of assets and liabilities. In 2020, the balance of deferred of income tax and social security shifted from a BRL 1.1 billion liability into a BRL 770 million asset.

Of particular relevance in the variation are the effects of foreign exchange fluctuations arising from the adoption of the cash regime for income tax purposes. Temporary losses from foreign exchange variations of book income were excluded from the taxable base for income tax purposes, resulting in a deferred asset of BRL 888 million in addition to BRL 637 million in losses from financial instruments (swaps), which FY 2020’s foreign exchange variation also affected.

Fixed Assets

The balance of fixed assets on December 31, 2020, was BRL 16,7 billion, equivalent to 47% of total assets, from BRL 13.2 billion on December 31, 2019, equal to 38% of total assets. As concerns the variation in the line, particular emphasis is due on the disbursement of BRL 4 billion in 2020 associated with the Puma II Project and the acquisition of International Paper do Brasil Ltda assets in the amount of BRL 410 million, considering the historic cost of the acquisition and the goodwill gains made in the operation.

Right-of-use assets

On December 31, 2020, the balance of right-of-use assets was BRL 808 million, up 64% from Page 180 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

2019 because of new land lease operations executed in FY 2020. Right-of-use assets concern the rental/lease of land, machinery, equipment and buildings for which the company has asset- side agreements.

Biological assets

The Company’s biological assets valued at fair value were BRL 4.7 billion on December 31, 2020, equivalent to 13% of total assets, in line with 2019 amounts.

CURRENT LIABILITIES

Suppliers

On December 31, 2020 the balance of supplier accounts payable was BRL 2 billion, up 98% from 2019’s BRL 1 billion. The increase is significantly due to procurement for the Puma II Project, which amounted to BRL 4 billion in 2020, to the increase in average days’ payment from 51 days in 2019 to 67 days in 2020, and to drawee risk operations that the Company offers to suppliers, from BRL 137 million at yearend 2019 to BRL 249 million at yearend 2020.

NON-CURRENT LIABILITIES

Loans and financings

The balance of loans and financings was BRL 653 million in current liabilities and BRL 28.9 billion in non-current liabilities on December 31, 2020, from BRL 702 million in current liabilities and BRL 21.5 billion in non-current liabilities on December 31, 2019, for a 4% YoY increase in the total balance. The balance of loans and financings, considering both current and non-current liabilities, corresponds to 70% of total liabilities and shareholders’ equity on December 31, 2020, versus 64% on December 31, 2019.

Of particular relevance is the 28% appreciation of the US Dollar against the Brazilian Real in 2020, raising the outstanding balance in Brazilian Reais of the foreign currency=-denominated debt to 78% of the balance of Loans and Financings at yearend 2020.

Debentures

The balance of debentures as current and non-current liabilities was BRL 1.8 billion, equivalent to 5% of total liabilities, on December 31, 2020, steady from FY 2019. In FY 2020 the Company amortized the 7th issue (1st series), capitalizing the converted debentures as equity stock in the amount of BRL 399 million, partly offset by the restatement of financial instruments (swaps) in the amount of BRL 526 million due to the effects of foreign exchange variations.

CURRENT ASSETS Page 181 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

Cash and cash equivalents and securities

The Company had a balance of BRL 9.7 billion in Cash and cash equivalents and securities at yearend 2019, representing 28% of total assets, up BRL 2.7 billion from yearend 2018 (BRL 7 billion). This is mainly due to new funds raised and operational cash generation in the period.

Customer accounts receivable

The balance of customer accounts receivable was BRL 1.9 billion in December 31, 2019, down 9% from December 31, 2018’s BRL 2 billion. The decrease is due to lower selling prices, particularly in the pulp segment.

Average days’ payment was approximately 86 days for domestic sales and 117 days for foreign sales.

Inventories

On December 31, 2019, the Company had BRL 1.3 billion in inventories, up 10% from yearend 2018. The increase is due to increased pulp production volume.

NON-CURRENT ASSETS

Taxes recoverable

The balance of taxes recoverable in non-current assets as of December 31, 2019, was BRL 1.9 billion, up from the BRL 1.3 billion recognized on December 31, 2018. The increase is mainly due to the tax credits gain arising from the court sentence that passed into res judicata, recognizing the Company’s claim to remove ICMS from the PIS and COFINS taxable base, retroactive to April 2002, in the amount of BRL 1 billion.

Fixed assets

The balance of fixed assets on December 31, 2019, was BRL 13.2 billion, equivalent to 38% of total assets, versus BRL 12.3 billion on December 31, 2018. Concerning the change, we underscore disbursements for the Puma II Project for the construction of two paper mills with integrated pulp production, in the amount of BRL 1.3 billion.

Right-of-use assets

On January 1st, 2019, the Company adopted the new technical accounting standard CPC 06 (R2)/IFRS 16 – Lease Operations, which requires balance-sheet recognition of asset leases, rent, and land leases.

Because of IFRS 16, on December 31, 2019, the Company recognized BRL 494 million in connection with rights to use land, machinery, equipment and buildings for which it maintains rent/lease agreements.

Biological assets Page 182 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

The Company’s biological assets valued at fair value were BRL 4.7 billion on December 31, 2019, equivalent to 14% of total assets, and BRL 4.6 billion on December 31, 2018, for 13% of total assets. The main element in the increase balance corresponds to standing trees purchase agreements entered into over the course of 2019.

CURRENT LIABILITIES

Suppliers

As of December 31, 2019, the balance of suppliers was BRL 1 billion, up 13% from 2018’s BRL 904 million. The increase is due to the greater average days’ payment, from 50 in 2018 to 51 in 2019, due to drawee risk operations that the company offers to suppliers, in addition to investment in fixed assets acquisitions associated with Puma II.

NON-CURRENT LIABILITIES

Loans and financings

The balance of loans and financings was BRL 702 million in current liabilities and BRL 21.5 billion in non-current liabilities on December 31, 2019, from BRL 1.9 billion in current liabilities and BRL 16.9 billion in non-current liabilities on December 31, 2018, up 18% YoY. The balance of loans and financings, considering current and non-current liabilities, was 64% of total liabilities and shareholders’ equity as of December 31, 2019, from 55% on December 31, 2018.

The increase in gross debt arises from funds raised in connection with the Company’s liability management process, lengthening average maturity from 48 to 96 months at yearend 2019, and the investments associated with the Puma II Project. Over the course of 2019 the Company secured new financing, such as the issue of Agribusiness Receivables Certificates (CRA) in the amount of BRL 2 billion, and the issue of bonds for a total USD 750 million.

Also noteworthy is the 4% gain of the US Dollar versus the Brazilian Real in 2019, increasing the outstanding foreign currency-denominated debt, which corresponded to 76% of the balance as of December 31, 2019.

Debentures

The balance of debentures, considering both current and no-current obligations, was BRL 1.8 billion, or 6% of total liabilities, on December 31, 2019, versus BRL 663 million at yearend 2018. The increase is due to the 12th issue, in the amount of BRL I billion, which the Company carried out in 2019.

Deferred income tax and social contribution

As of December 31, 2019, the balance of deferred Income tax and social contribution constituted on temporary differences and recognized in the balance sheets as assets and

Page 183 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

liabilities correspond to BRL 1.1 billion in liabilities, from BRL 960 million on December 31, 2018. The change seen in 2019 corresponds to the amount won in the legal proceedings to exclude ICMS from the PIS and COFINS taxable base.

The Company’s main temporary differences concern the fair-value valuation of biological assets, the cost assigned to fixed assets (land), which will have no cash effect when realized, and the deferred foreign exchange rate variation and credits on losses and accumulated negative bases.

10.2. Operational and financial income a) Operational income i. description of all relevant components of revenues The Company positions itself the domestic market with emphasis on the packaging paper and packaging paper for food, liquids (refrigerated and dairies), beverages (sodas and beers), hygiene and cleaning, personal care, and pharmaceuticals, in addition to paper bags (cement, mortar, flour, seed and other) and fluff pulp. As for the international market, growth is based on the markets for pulp, liquid packaging board as global supplier to Tetra Pak, folding boxboard (frozen products, hygiene and cleaning – Europe, USA and Mercosur) and kraftliner. The Company sold 53% of its sales volume in the domestic market in 2020. The domestic/international sales mix is an important element in net revenues formation. The table next shows the volume of sales and net revenues from sales for the past three fiscal years.

The sales mix across regions is also a very important element in the Company’s sales breakdown, as prices, freight and delivery terms vary between locations.

ii. Factors materially affecting operational results Page 185 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

In 2020, the Company acquired the Brazilian packaging papers and corrugated cardboard business of International Paper do Brasil. Under the operation, the fiscal year’s results recognized goodwill in the amount of BRL 206 million in the process of measuring the fair value of the assets and liabilities acquired. In 2019, Klabin recognized a one-time tax credit in connection with a res judicata court ruling in favor of the Company’s claim to exclude the ICMS tax bill from the PIS and Cofins taxable base, with a positive effect on the Company’s EBITDA in the amount of BRL 620 million. b) Change in revenues associated with changes in prices, foreign exchange rates, inflation, volume, and the introduction of new products and services The prices of the Company’s products vary depending on the balance of supply and demand in the domestic and international markets. Products are priced differently in the various segments in which the Company operates, and are under heavy influence of GDP. Inflation, economic activity level in Brazil and around the world, interest rate changes, tax burden, variation of the Brazilian Real against foreign currencies, the market price of pulp, paper shavings price, and natural phenomena affecting wood supply. Prices are usually cyclic and subject to factors beyond Klabin’s control. The international prices of paper and pulp are, in most cases, denominated in US Dollars. The Company exported 45% of its sales volume in 2020. Therefore, the foreign exchange rate is an important element for the company’s net revenues. In the past three years, the exchange rate (selling rate) varied as follows:

2020 2019 2018 2020/2019 2019/2018 Foreign exchange BRL/US$ BRL/US$ BRL/US$ % % Average US Dollar 5.16 4,03 3,87 28% 4% Closing US Dollar 5.20 3,95 3,66 32% 8%

Net sales revenue in the foreign market was BRL 4.9 billion in 2020, up 19% from the previous year, when export revenues were BRL 4.2 billion. In 2018, net export revenues were BRL 4.5 billion. The Company’s revenues and costs are affected by inflation. The domestic market prices of paper products, as well as the cost of production inputs and labor, tend to vary with Brazilian inflation indices. c) The impact of inflation, of price changes for the main inputs and outputs, of foreign exchange rates, and of the interest rate on the issuer’s operational and financial results For materials, in addition to the IPCA, the variation of certain commodities – such as fuels – applies to determine freight price adjustments. The Company’s operational results are influenced by inflation and foreign exchange rate variations, as, in 2020, 41% of net revenues came from foreign sales. Financial results are affected by changes in the Funds Rate and other rates affecting financial investments; in the TJLP, which applies to domestic currency-denominated debt, and the foreign exchange rate, which applies to foreign currency-denominated financing.

10.4. Significant changes in account practices – auditors’’ reservations and emphasis a) Significant changes in accounting practices

No material accounting practice changes worth emphasizing took place between fiscal years 2020 and 2018. In FY 2019, the IASB and CPC approved and issued new standards, which went into force and were effectively adopted from January 1, 2019.

(i) IFRS 16- Lease Operations (CPC 06 (R2) - Operações de Arrendamento Mercantil) The new standard replaces IAS 17 - "Lease Operations” and constructions thereof, providing that lessees must now recognize the liability from future payments of “lease liabilities” and the right to use the leased asset “right-of-use assets” in connection with virtually all lease agreements.

(ii) IFRIC 23 – Uncertainty Surrounding the treatment of Taxes on Earnings (CPC 22 - Incerteza sobre Tratamento de Tributos sobre o Lucro)

The new interpretation provides requirements for recognition and measurement in situations where the Company has defined, during the process of ascertaining taxes on earnings (Income tax and social contribution), the use of uncertain tax treatments that may come into question before tax authorities. The Company’s Management now considers aspects of IFRIC 23 (ICPC 22) and has revised judgments made while ascertaining Income tax and social contribution, concluding that no uncertain treatments have been used in its financial statements, as all procedures associated with payment of taxes on earnings are backed by the applicable law and legal precedent.

b) material effects of accounting practice changes The table below shows the balance-sheet effects in BRL thousands of the adoption of the new CPC 06 (R2)/ IFRS 16 standard on July 1st and December 31, 2019:

10.5. Critical accounting policies The Company’s consolidated financial statements are prepared according to the International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB), in line with accounting practices embraced in Brazil, under the standards published by the Comitê de Pronunciamentos Contábeis - CPC. The Company understands that the items next are critical, requiring estimates and subjective judgment on an uncertain future, and are needed to determine the amounts provided in its financial statements, as they depend on the definition of assumptions like discount rates, customer analyses, the definition of the useful life of assets, forecasting results based on the budget, estimated losses, productivity, forecast of future events, market prices, and more. The assumptions made are based on the Management’s knowledge and experience, on the best benchmarks available from the market, on predicted future events, and on expert support as needed. Provision for bad credits

The Company provisions for bad credits based on individual analyses of amounts receivable and estimated probably losses realizing receivables. The credit risk of the Company’s operational activities is managed by means of specific rules governing customer acceptance, credit analysis and establishment of exposure limits by customers, all of which are periodically revised, in addition to constant monitoring of customers’ financial health as a means to make sure that amounts owed the Company are in fact collected.

The Company’s policy is to provision for bad credits based on an individual analysis of amounts receivable, considering: (i) the concepts of effective losses and expected losses, taking account of the probability of default events occurring in the following 12 months, (ii) financial instruments experiencing significant credit risk increase, but no objective evidence of impairment; and (iii) financial assets showing objective evidence of impairment.

The procedure requires a certain degree of discretion from Management because of the uncertain assumptions involved in the process, such as the financial standings of customers and the market’s economic trends.

Provision for losses realizing inventories

The Company provisions for probable losses from (i) inventories of products that have been discontinued or we intend to discontinue; (ii) surplus inventories of raw materials relative to projected sales of the products for which they are used in the coming twenty-four months; (iii) inventories of finished products that will expire before they can be sold; and (iv) unused maintenance inventories. These provisions are updated as of each balance-sheet closing date.

The activity’s critical process lies in evaluating the obsolescence of inventories, considering individual analysis of the items according to the judgment of the professionals involved, leaving to Management the definition of standards and internal procedures for periodical evaluation of inventories.

Although this is a critical process because of the necessary judgment, the Company’s main products (paper, packaging, bags and wood) are not perishable, and, even if not used for sales, Page 190 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

they may be re-processed and used in new production processes.

Deferred income tax and social contribution

The Company recognizes deferred tax assets and liabilities based on the difference between book values and the taxable base of assets and liabilities. The Company regularly reviews the realization of deferred tax assets.

The critical nexus for deferred taxes relates with Management’s judgment of the realization of the net deferred tax asset, keeping it on the books as long as probable, as supported by results forecasts, but the amount thereof is subject to uncertainty as it depends on the materialization of forecast taxable income in future periods.

The Company chose early adoption in 2014 of Law 12.973/14, which enable neutralizing the current tax effect on income accounts, which receive different treatments under the tax law and the new Corporations Law.

Fixed and intangible assets

The Company uses the linear depreciation method set based on the assessment of each asset’s useful life, based on the expected generation of future economic benefits, with the exception of land, which does not depreciate. Assessment of assets’ useful life is reviewed annually and adjusted as needed, and may vary based on each unit’s technological currentness.

Financial charges are capitalized on fixed assets when they are incurred on ongoing fixed assets formed, where applicable.

Expenses on new products and techniques research are recognized in each fiscal year as expenses, as they are incurred.

Useful-life determination is a critical process and demands subjective judgment. It is inherently uncertain due to technological change or other factors that may cause early obsolescence of fixed assets. If a need arises to make relevant changes to the original assumptions, depreciation expenses, obsolescence write-offs and the book value of fixed assets may diverge materially from the originally adopted assumptions.

Asset impairment

The balance of fixed and other assets is revised annually to identify evidence of non-recoverable losses or events and chances indicating that the book value may not be recoverable.

In the estimates used to define an asset’s recovery value, estimated cash flows are discounted to their present value using a discount rate that reflects the current market valuation of the time- value of money and asset-specific risks. This discount rate is set individually for each asset, unless an asset generates no cash inflows. When a loss is identified, it is recognized in a period’s results at the amount by which an asset’s book value exceeds its recovery value.

Page 191 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

Impairment valuation is critical because it can be influenced by different internal and external factors, such as economic and industrial trends, interest rates, strategic business changes, and changes in the types of products offered to the market.

Biological assets

Fair-value valuation of biological assets, which the Company does quarterly, takes account of certain estimates such as: price of wood, discount rate, forest harvest plans, and productivity volume, all of which are subject to uncertainty and whose variations may affect future results. A fair-value increase or decrease is determined as the difference between the fair value of biological assets at the beginning and end of the relevant period.

Tax, social security, labor and civil provisions

These provisions arise from administrative and/or court proceedings inherent to the Company’s regular activities. Tax, social security, labor and civil provisions are reviewed by in-house counsel, and lawyers and experts retained by the Company, and are quantified based on criteria that enable proper measurement. They are restated to the as-of date of each balance sheet.

Provisions are made for court proceedings deemed to be probable losses. For those where a loss is deemed possible, the Company merely discloses the cases and amounts involved, with no provisioning; and for those where a loss is deemed remote, the Company neither discloses risks nor forms provisions, as required by the accounting practices in force in Brazil.

In court cases where the Company is the plaintiff, no amounts are recognized in financial statements, according to the accounting principle of prudence. The practice in place is to only recognize such assets after the sentences thereunder pass into res judicata.

Combined businesses

A business acquisition takes place when the set of activities and assets acquired includes at least one input and one substantive process that, taken together, contribute significantly to the ability to generate output. Combined businesses are recognized by means of the application of the acquisition method. The cost of an acquisition is measured as the sum total of the assets transferred, valued at fair value on the date of acquisition, in the light of the Purchase Price Allocation (PPA) to the acquired assets and liabilities. A combined business produces a premium when the acquisition price exceeds the value of the net assets acquired (net identifiable assets acquired and liabilities accepted). If the acquisition price is lower than the fair value of the net assets acquired, the difference will be recognized as a beneficial acquisition in the fiscal year’s bottom line. PPA effects are allocated to intangible assets when they emerge from a premium for future returns, or allocated to assets and liabilities when valuation indicates a market premium.

Acquisition of brands involved in royalties and takeover of Sogemar

On November 26, 2020 an Extraordinary General Meeting approved the takeover of SOGEMAR – Sociedade Geral de Marcas (Sogemar), the owner of the brands involved in the royalties agreement.

With the takeover, Klabin becomes the owner of Sogemar’s brands, and Sogemar ceases to exist on the date, thereby extinguishing the respective license agreement and payment of royalties in connection with such brands.

The takeover involved substitution of the shares of Sogemar through the issue of sixty-nine million, three hundred and ninety-four thousand, six hundred and ninety six (69,394,696) new common shares of the Company, all nominative and without par value, for Sogemar’s partners, with a BRL 144 increase in the Company’s shareholders’ equity.

c) new products and services (including description of disclosed research underway, total amount spent in research for new products or services development, disclosed projects underway, and total amount spend by the Company on new products or service development) Klabin’s competitive evolution, from the performance of its forests and production processes to management of its products’ impacts, is intrinsically connected with constant investment in Research, Development and Innovation. As the paper and packaging markets become more and more challenging, and with entry into the world pulp market with the operational startup of the Ortigueira (PR) plant and the motto of Sustainability and renewable materials, the Company has been increasing its R&D&I investments.

In 2020, Klabin was devoted to standing as a global benchmark for responsible solutions in response to constant societal changes, offering renewable, recyclable and biodegradable multipurpose forestry products. To contribute to a sustainable economy and inspire consumer choices, the Company prioritizes the planet’s prosperity, which principles are aligned with the KODS (Klabin Sustainable Development Goals), creating value for its investors, employees, business partners and communities.

With a more comprehensive view and a more strategic action, the R&D&I area acts on several links along the production chain:

 Perfecting processes for improving species, planting and handling of pine and eucalyptus to achieve increasing productivity;  Developing new products and improving existing processes to adapt them to customers’ needs or to better economic and environmental performance;  Solutions for the issues of the physical and mechanical properties of papers and packaging, such as barriers (water, steam, fat, oxygen), porosity, permeability and roughness, and of conversion (cutting, folding, pasting, closing and printing);  Review of product performance in terms of the environment, quality, productivity, health and safety.

Klabin’s Forest Research, Development and Innovation is devoted to projects included in different research tracks:

 Genetic Improvement of Eucalyptus;  Genetic Improvement of Pine; Page 197 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

 Cloning;  Forest Biotechnology;  Plant Health;  Nutrition and Forestry;  Ecophysiology.

2020 Highlights:

 Forming genetic improvement populations of pine and eucalyptus in PR and SC, in pursuit of medium- and long-term genetic gains for the purposes of recommending new hybrids with greater fiber production potential;  Expansion of the Eucalyptus and Corymbia genetic base by means of the introduction of new genetic material in an attempt to secure new alleles for adverse conditions, such as climate change and expansion into new production sites;  Development of genetic improvement strategies for the Corymbia genus from the selection of hybrid clones with high productive potential, for the purposes of producing new clones appropriate for hydric stress conditions, as well as to increase basic wood density;  Protecting 6 cultivars of high-productivity hybrid eucalyptus clones to ensure Klabin’s genetic assets;  Increasing the production capacity for genetically improved seeds by means of orchards of Pinus taeda, Pinus maximinoi and Pinus tecunumanii;  Enabling operational-scale production of saplings of the elite Pinus taeda family through vegetative propagation;  Development of 250 new clones of Pinus taeda via somatic embryogenesis to expand the clonal selection program’s experimental network;  Continuation of the internal technical committee called FIP (Forest, Industry and Research), with a focus on understanding the quality characteristics of wood and the solution of deviations that may impact the quality of the end product;  Installation of 32 weather forecasting and climate monitoring stations in Klabin’s area of activities in PR;  Major advance in the Forest Biotechnology area, with the development and implementation of biotechnology techniques such as somatic embryogenesis and molecular markets applied to the selection of superior clones;  Development of a computerized research management and information security system (Labware/Lims) for the forestry research base.

Klabin’s Industrial Research, Development and Innovation area addresses five research tracks:

 Development of forest raw materials for pulp, paper and new materials;  Paper optimization and new applications, with a focus on functional barriers;  Bio-refinery (multiple uses of the first base, in particular lignin);  Optimization of environmental processes, re-use of process byproducts, reduced water, energy and steam consumption;  Nanotechnology – cellulose fractions at the micro- or nanoscale and application to new products.

Industrial Research achieved several accomplishments in 2020, which was a promising year despite the great challenges faced. Progress continued in quality assessments of wood from new genetic materials planted at Klabin, with the following highlights:

 Pinus maximinoi, as a source of long fibers, with increased forest production potential and distinctive end-product quality. The fruits of these studies were recognized by international awards such as best Technical Paper presented in 2019, in the Tappi Peers

event in the USA, in addition to one more doctorate earned in 2020.

 Evaluation of the wood quality of more than 1,123 Eucalyptus spp. trees by application of the Near Infrared technology for quick prediction of the wood’s chemical, physical and pulping properties. For added efficiency, the R&D&I area maintains partnerships with providers of equipment and inputs, in addition to relying on support from research institutes and universities in Brazil and abroad.

It is also worth mentioning actions intended to add properties to paper as a means to improve its effectiveness as a sustainable packaging material in functional barrier form, meeting the increasing needs of the market and society, as well as continued progress in terms of intrinsic properties, such as mechanical resistance and surface quality. Gains were made in the development of barriers against various substances (water, steam, fat, oxygen), achieving more effective results in line with stakeholders’ expectations.

In addition to the BRL 70 million invested in 2015-2017, Klabin will inject approximately BRL 180 million in Industrial and Forest Research in 2019-2021, including a new Pilot Plants park whose operations began in November 2019 for the purposes of new products development. In line with the investment in the Pilot Plant, the company’s first lignin extraction plant developed a product that is unique in Brazil: kraft lignin from pine. More than 4 tons of the material have been produced, materializing over 20 partnerships for R&D projects and future clients. The microfibrillated cellulose plant enabled holding five industrial tests focusing on the development of new papers and cardboards with distinctive features compared with the competition. At the same time, several generations of cellulose-base products were developed for application in other markets, culminating in the success case “Hand Sanitizing Gel Production with Cellulose-Based Thickener”. The application enabled developing a new, fully renewable and sustainable, ingredient for cosmetics from MFC (microfibrillated cellulose).

Given the replacement of non-renewable materials with biodegradable ones based on cellulose fibers, nanotechnology projects using cellulose fractions on the micro- (microfibrillated cellulose – MFC) and nano- (nanocrystalline cellulose) scales progressed to pilot applications to paper and packaging materials.

Another focal point in the application of lignocellulosic materials (MFC, cellulose and wood fines) pursued production of plastic-substitute composites. This are may provide a new market for more sustainable materials. In a partnership with Senai, the Company developed a faceshield with 10% cellulose as a replacement for polyethylene that was distributed at all Klabin healthcare units to support the combat against Covid-19.

Sustainability is an ever-present beacon for the Company’s research and, in pursuit of zero waste-to-landfill, an initiative at the Rio Negro (PR) unit enables using sludge from the Effluents Treatment Station for local brick manufacture.

Advances in research on the use of wood extracts and forestry waste, leading green fuels – Crude Tall Oil and BioOleo – to make use of 100% of the forest potential, playing a key role in the world’s main groups and intellectual institutions as concerns inputs.

With the Puma II Project, Klabin will have available a line with the capacity to produce 450 Page 199 of 348

13.1. Description of the compensation policy or practice, including as concerns the non- Statutory Executive Board. a) Purposes of the compensation policy or practice, informing whether or not a compensation policy has been formally approved, the corporate body responsible for approval, and, where the issuer discloses such policies, the Web locations where they may be viewed. The purposes of our compensation practices are as follows:

- to align the interests of employees with the Company’s and the shareholders’ strategy;

- to enable employee compensation to be competitive and attractive compared to the market at large;

- to recognize the efforts of Klabin’s high-performing employees, fostering a culture of meritocracy and attracting and maintaining talent;

- to make sure that executive compensation does reflect our short- and long-term results, in addition to individual performance.

Our compensation plan and the overall compensation of Management are approved by the Board of Directors and the General Meeting. Approval-related information may be viewed in full at https://ri.klabin.com.br/governanca-corporativa/assembleias-e-reunioes/.

b) Compensation breakdown, indicating: (i) Description of the components of compensation and the purposes of each Board of Directors and Fiscal Council

Our Board of Directors and Fiscal Council earn fixed monthly fees, as well as life insurance and healthcare as benefits.

Additional compensation is offered for committee membership.

Statutory Executive Board (CEO and other Statutory Officers)

Compensation of the Statutory Executive Board breaks down into monthly fees, short- and long-term incentives, benefits (life insurance, healthcare plan, grocery vouchers, meal vouchers, private pension plan, and medical checkup) and FGTS (Time-in-Employment Fund).

As concerns fixed compensation, that is, monthly fees, we aim to align with the relevant market’s median, as well as with the practices applicable to the benefits package.

As concerns variable compensation, that is, short- and long-term incentives, we aim for a position in the 3rd quartile of the market, strengthening the connection between compensation Page 244 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

and healthy and sustainable growth for Klabin, establishing indicators pegged to the business strategy and cycle, which enable closer alignment with the shareholders.

Furthermore, a large portion of long-term incentives arises from a matching program, where beneficiaries invest a portion of their short-term incentives to join. This enables aligning short- and long-term incentives, instilling a deeper sense of ownership in participants. The other portion of the long-term incentive is pegged to share-performance indicators, further reinforcing this alignment.

Non-Statutory Officers

Compensation of our Non-Statutory Officers is made up of monthly fees, short- and long-term incentives, and benefits (life insurance, healthcare plan, medication expenses support, meal vouchers, private pension, and medical checkup). It also includes labor rights as per the Law (paid vacation, 13th salary, and FGTS).

Our strategy for fixed compensation and short- and long-term incentives is the same as for the Statutory Executive Board.

(ii) Breakdown of total compensation

(iii) Calculation and adjustment method for each component of compensation

Page 246 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

The annual amount to be used for the overall compensation of management (Directors and Statutory Officers) is set at the Company’s Annual General Meeting.

Our annual compensation survey is supported by consultants Korn Ferry do Brasil. The survey covers companies whose characteristics are similar to Klabin’s and recognized by the market.

We use the information obtained to analyze our compensation practices for competitiveness, as well as to determine the need for any adjustments to our executive compensation.

Compared with the relevant market, we keep a market-median position for fixed compensation and in the 3rd quartile for variable compensation, strengthening be connection between compensation and the Company’s healthy and sustainable growth.

(iv) Reasons justifying the compensation breakdown

Fees/fixed compensation: it is our policy to position our reference compensation at the market median (P50) to maintain competitiveness. We thus strengthen the connection between compensation and Klabin’s healthy and sustainable growth.

Short-term variable compensation: helps make the compensation package more competitive compared with the market at large and provides the basis for participation in the LTI Marching plan. Because it also depends on the Company’s performance, it has even greater impact on aligning interests with shareholders. Our strategy for this component is to maintain a position in the market’s 3rd quartile (P75).

Long-term variable compensation: the long-term variable component is most relevant for aligning the interests of shareholders with the employees’ and as concerns talent retention and attraction, as it depends on the participants’ remaining with the Company for periods from three to five years, as well as on good performance on the part of Klabin’s shares. It has the potential to significantly increase participants’ compensation, and our strategy for this component is to maintain a position in the 3rd market quartile (P75).

Benefits: We believe that benefits are important to leverage the competitiveness of Klabin’s compensation package, as well as to ensure better living standards for our employees and their dependents. Our strategy for this component is to maintain a position in line with best market practices.

v) presence of members without compensation from the issuer and the reason for this

There are no members without compensation

Page 247 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

c) main performance indicators considered to determine each compensation component

For our short-term incentives program, parameters include financial indicators and individual goals measuring the performance of each employee. Corporate goals make up 75-80% of the total weight, and individual ones make up the remaining 20-25%. Indicators are financial operational, market-related, and ESG-related.

Individual goals are agreed at the beginning of each year and attainment is determined at the end of the year.

Since the 2020 hiring cycle, individual goals have been pegged to the KODS (Klabin Sustainable Development Goals), that is, they relate with each of the four theme axes proposed (renewable future, sustainable economy, prosperity for people, and technology & innovation). This reinforces the importance of managing the ESG culture and our commitment to long-term goals set for 2030, adopting the required short-term measures and rallying employees around this purpose.

¹KODS = Klabin Sustainable Development Goals. We organize in the light of the UN’s 17 sustainable development goals and prioritize 14 of them, which our sustainability programs and initiatives affect directly. They have been devised with short- (2021), medium- (2025) and long- term (2030) goals in mind, embracing our company’s values and needs, while maintaining a dialogue with the four theme axes that we prize: building a renewable future, contributing to a sustainable economy, prosperity for the people, and technology & innovation.

Concerning long-term incentives, we established two share-based programs to stimulate attainment of results and alignment of the interests of participants with those of the Company’s shareholders:

- LTI Matching: under this program, performance indicators apply indirectly, as the number of shares awarded to a participant depends on the amount invested thereby upon joining the program, such an amount to be a portion (up to 35%) of their short-term incentive. After the awarding, participants must await a three-year vesting period to receive the matching. See item 13.4 for additional information on the program.

Since 2016, Managers have become eligible for the program, and eligibility for Coordinators and Specialists came in 2018.

- LTI Performance: The purpose of the Program is to strengthen alignment with the Company’s strategy and the interests of Shareholders, conditioning receipt to the attainment of a performance goal, that is, TSR (Total Shareholder Returns) X Cost of Shareholders’ Equity

(Ke).

The target value is 25% of each executive’s short-term variable compensation target, based on the fees/salaries in force in January of the year when the program begins. This target value is converted into “virtual units”, considering the average share price in the final 30 trading days of the year preceding the plan in force. The plan has a duration of 5 years, and is contingent upon attainment of performance targets after this five-year period (vesting period), in addition to permanence with Klabin.

Once a performance target has been reached, in addition to the “virtual units”, executives shall be entitled, as additional LTI Performance yield, to an amount equivalent to the dividends and/or interest on shareholders’ equity paid by KLABIN S/A to shareholders during the vesting period. These amounts are converted into “virtual units” over the course of the five-year vesting period, and accumulated in a graphic account.

After the 5-year vesting period, in addition to determination of performance indicator attainment, the Board of Directors conducts a discretionary review that may modulate the final result by 10% more or less to mitigate exogenous impacts.

For the purposes of payment of the LTI Performance, as long as the performance target has been met, the total number of “virtual units” in each Plan shall be converted into monetary amounts at the unit’s price (KLBN11), considering the average of the last 30 trading days prior to plan close. Payment to the executive shall be made in cash.

Only Statutory and Non-Statutory Officers shall be eligible for LTI Performance.

¹TSR = [(Final share price – Initial share price) + Dividends]/Initial share price

²Ke = Risk-free interest rate + Business risk factor * (Market index yield – Risk-free interest rate)

d) how the Company structures compensation to reflect the evolution of performance indicators

The short-term incentive paid may vary between 0% and 150%, depending on the annual targets attained. We thereby also guarantee that the LTI Matching plan will reflect this evolution, as the number of assets awarded to participants depends on the percentage of the STI invested in the plan.

The LTI Performance plan, by its turn, is directly aligned with the indicators, as the amount participants will receive depends on TSR and Ke performance of the Company’s shares as

Page 249 of 348

Reference Form- 2021- KLABIN S. A. Version: 7

described before.

e) how the compensation policy aligns with the Company’s short-, medium- and long-term interests

In the short term, the Company pursues alignment by means of competitive salaries and a benefits package compatible with the market, enabling the attraction of skilled and high- performance workers. In addition, our short-term incentives are pegged to financial performance indicators (such as EBITDA, Net revenues, Working Capital) and individual targets that measure each employee’s performance.

For the long term, we achieve alignment by means of the LTI Matching plan, which is based on units and requires participants to make an initial investment. Also in the long term, we have the LTI Performance plan, which aligns Officer compensation with the units’ market performance by means of the TSR and Ke indicators, as discussed before.

f) presence of compensation supported by subsidiaries, controlled entities or directly or indirectly controlling shareholders

No form of compensation exists that meets these criteria.

g) presence of any compensation or benefits pegged to the passing of certain corporate events, such as divestment of the Company’s controlling stake

No compensation or benefits are pegged to the passing of corporate events. However, in the event of a control change, the vesting period of the LTI plants will be anticipated, releasing participants from giving Klabin preemptive rights over the shares acquired and anticipating the conveyance of title over the shares.

h. Board of Directors practices and procedures in place to define individual compensation of the Board of Directors and the Executive Board, indicating

i. The issuer’s bodies and committees involved in the decision-making process, identifying the manner of their involvement

Our compensation plan and the overall compensation of the Management require the approval of the Board of Directors and General Meeting. Information on approval thereof can be viewed

in full at https://ri.klabin.com.br/governanca-corporativa/assembleias-e-reunioes/.

In addition, the Board of Directors counts on the advice of the Compensation Committee, which is responsible for examining and discussing the compensation guidelines for the members of the Executive Board, including the compensation criteria (fixed and variable) and benefits, ensuring that these guidelines are compatible with the risk management policy, with the goals and the financial situation of the Company. In addition, the Compensation Committee advises the Board of Directors regarding the overall compensation of the managers.

ii. Criteria and methods used to set individual compensation amounts, indicating whether or not surveys are used to determine market practices and, if so, the studies’ comparison criteria and scope

Our annual compensation surveys have the support of consultants Korn Ferry do Brasil. The survey covers companies with similar characteristics to Klabin’s and recognized by the market.

The information is used to analyze our compensation practices’ competitiveness, as well as to establish the need for any compensation adjustments as concerns our employees.

Compared with the relevant market, we maintain a median position for fixed compensation and a position in the 23rd quartile for variable compensation, strengthening the link between compensation and the Company’s healthy and sustainable growth.

iii. how often and in what manner does the Board of Directors review the adequacy of the issuer’s compensation policy

Annually.

13.16 Other relevant information The amounts shown in items 13.2 and 13.3 are book amounts, that is, they concern Klabin’s expenses provisioned for the variable compensation plans and, since the last fiscal year, awards under the LTI Performance plan are no longer treated as bonuses, but rather as share-based compensation.

INSS at the Company’s expenses

According to CVM Proceeding No. 19957.007457/2018-10 and the meeting of 12/08/2020, the amount corresponding to INSS at the Company’s expenses is no longer treated as a “benefit of any type”, and is therefore not declared in item 13.2. For the sake of transparency, however, Klabin lists the respective amounts for fiscal years 2018, 2019 and 2020, and the forecast 2021 amount:

INSS at the Company’s expense, 2021: BRL 8,292,894.57

INSS at the Company’s expense, 2020: BRL 7,521,958.87

INSS at the Company’s expense, 2019: BRL 5,795,107.82

INSS at the Company’s expense, 2018: BRL 6,287,353.05

The calculations in items 13.3, 13.11 and 13.13 were also entirely reprocessed, disregarding the INSS at the Company’s expenses.

Share-based compensation plan

Given the nature of the compensation plants based in share of the Company, none of which include options, all items concerning options are not applicable.

Management and Fiscal Council Compensation

The compensation earned by Management and the Fiscal Council in fiscal year 2021, as provided in items 13.2 and 13.3 hereof, represents the proposal to be submitted to the shareholders at the Annual General Meeting to be held on March 24, 2021.

14.2. Relevant changes in the numbers disclosed in foregoing item 14.1: Concerning the behavior of the headcount in 2020, no significant differences emerge from 2019. As for the number of outsourced workers, the increase is due to activities associated with the Puma II Project, outsourcing of silviculture teams, wood transportation from Klabin operations, particularly in the South, and increased demand for packaging in the last quarter, which required increasing the number of temporary workers, a seasonal effect. Impact on all Brazilian regions at corrugated paperboard units.

Concerning the behavior of the headcount in 2019, no significant differences emerge from 2018. As for the number of outsourced workers, the increase is due to higher production, outsourcing of forestry teams, and wood transportation from Klabin operations, particularly in the South. Concerning the behavior of the headcount in 2018, no significant differences emerge from 2017. The largest difference occurred in the Southeast due to a redistribution of production in Brazil. As for the number of outsourced workers, the main difference occurred in the Northeast because of increased workforce to meet the operation’s demand. In the other regions, the changes seen arise from ordinary needs stemming from the activity’s maintenance and production processes.

14.3 Employee compensation policies, informing: a) Wages and variable compensation policy

The purposes of our compensation practices are as follows:

- to align the interests of employees with the Company’s and the shareholders’ strategy;

- to enable employee compensation to be competitive and attractive compared to the market at large;

- to recognize the efforts of Klabin’s high-performing employees, fostering a culture of meritocracy and attracting and maintaining talent;

- to make sure that executive compensation does reflect our short- and long-term results, in addition to individual performance.

Our annual compensation survey is supported by consultants Korn Ferry do Brasil. The survey covers companies whose characteristics are similar to Klabin’s and recognized by the market.

We use the information obtained to analyze our compensation practices for competitiveness, as well as to determine the need for any adjustments to our executive compensation.

Compared with the relevant market, we keep a market-median position for fixed compensation and in the 3rd quartile for variable compensation of the Manager level and up. At the Coordination level and below, we adopt the market median for all compensation components, strengthening be connection between compensation and the Company’s healthy and sustainable growth.

b) Benefits policy

The Company offers a competitive benefits package, in line with market practices.

The benefits package includes health care, supplementary retirement, dental care, life insurance for employees and their dependents including handicap coverage, grocery vouchers, meal vouchers, transport vouchers, discount agreement with drugstores, paycheck loans, support (day-care and special needs), support program for employees and dependents facing financial problems, legal, psychological and social advice, and supplementary sick pay.

Temporary workers hired through labor agencies receive life insurance and meal and transport vouchers.

In 2019 the Company joined the Citizen Company Program, extending 6-month maternity leave and 20-day paternity leave to all employees.

c) features of share-based compensation plans for non-management employees, indicating: (i) the beneficiary group; (ii) exercise terms; (iii) strike price; (iv) exercise period; and (v) Page 282 of 348

number of shares committed to the plan

The Company has in place an incentive plan based on shares (converted into Units) for its executives that has been duly approved by the CVM, and is discussed in detail in item 13 hereof.

LTI Matching was initially exclusive for Statutory and Non-Statutory Officers. Since 2016, Managers became eligible, and Coordinators and Specialists gained eligibility in 2018.

LTI Performance remains exclusive for Officers, whether Statutory or not.

Because the share-based compensation plans include no options, no exercise conditions, exercise periods, or strike prices apply.

Under LTI Matching, participants must invest a portion of their short-term incentives to join the program and await a three-year vesting period. Under LTI Performance, participants must meet the performance conditions, as described in items 13.1 and 13.4, and await a five-year vesting period.

Similarly, to enable proper management and maintain a cooperative atmosphere, employees and their unions are informed of any significant operational changes. The Company values collective bargaining with union representatives, as it does freedom of association. All employees are covered by collective bargaining agreements.
