1. Message from the Board São Paulo, March 2021.

Dear Shareholder,

The year 2020 was marked by the crisis triggered by the spread of the new coronavirus (COVID-19), which required quick decisions to ensure the health and safety of everyone. Faced with a series of uncertainties, we believe that the role of the Company was to care for its employees, which is why measures such as home office, intensifying the hygiene of factory areas and reinforcing communication were the first deliberations carried out in the Crisis Committee, created to centralize information and make decisions in an agile, efficient and transparent way. We also prioritize being proactive and collaborating with society to combat the effects of COVID-19. We join with large corporations to gather all possible help and, in parallel, we seek to serve hospitals and institutions in the most critical regions, bringing products and necessary supplies to ensure patient care. In total, these donations totaled more than R$ 10 million. In operations, after the first months of the crisis, when we had to make difficult decisions such as the suspension of operations from almost all units, we lived a period of unexpected demand expansion, which led us to end 2020 with the best result in the history of Duratex. Still, the continuous improvement in cost management in the Wood Division, coupled with Deca's agility to adapt to the scenario, strengthening its commercial actions on different fronts and the important evolution in the process of capturing synergies between Ceusa and Portinari, made it possible anticipate our 2020-2025 growth agenda and end the year with a positive recurring Economic Value Added (EVA) in all Divisions. The speed of our actions also made it possible to maintain all of the Company's growth projects, in particular the construction of the new dissolving wood pulp unit, which is on schedule and within the budget. Thus, in 2020, we were able to overcome the moments of apprehension and transform the difficulties into learning and evolution opportunities, in addition to consolidating the strategic movements made in recent years, with an emphasis on consistent strategic planning, cultural change and the search for sustainable results. In view of these advances, we are optimistic for the coming year, even though the challenges of the pandemic persist, and prepared to overcome adversity and evolve in our journey of growth. Due to the effects of the COVID-19 pandemic on society and in line with the recommendations of the Ministry of Health for the population to avoid events and agglomerations, Duratex will hold the Ordinary and Extraordinary General Meeting on April 29, 2021, at 11 a.m., in exclusively digital form. Sincerely,

Alfredo Egydio Setubal e Salo Davi Seibel Co-Chair of the Board of Directors

c) Establishment of the number of full and alternate members to compose the Board of Directors and election of the members of the Board of Directors: According to the Brazilian Corporation Law, the election of members of the Board of Directors can be carried out by majority vote, multiple voting process or separate vote. As the various voting procedures may have an impact on the fixing of the number of full and alternate members of the Board of Directors, the voting processes were detailed on pages 8 and 9 of this document, for a better understanding of the dynamics of this election. The Company's Bylaws provide that the Board of Directors will be composed of 5 to 9 full members and alternate members, elected by the Meeting. The unified mandate of the directors is 1 year, with reelection permitted. At the Shareholders' Meeting of April 29, 2021, the Controlling Shareholders will propose the provision of 9 full members, two of which 3 will be considered independent, in addition to three (3) alternates on the Company's Board of Directors. Thus, the Controlling Shareholders will propose the election of the persons listed below to be members of the Board of Directors:  As full members: Alfredo Egydio Arruda Villela Filho Alfredo Egydio Setubal Andrea Laserna Seibel Helio Seibel Juliana Rozenbaum Munemori (*) Márcio Fróes Torres (*) Raul Calfat (*) Ricardo Egydio Setubal Rodolfo Villela Marino (*) Independent  As alternate members: Alex Laserna Seibel Alexandre de Barros Paula Lucas Setubal The full members may be replaced by their alternates as follows: full members Andrea Laserna Seibel and Helio Seibel with alternate Alex Laserna Seibel; full members Alfredo Egydio Arruda Villela Filho and Rodolfo Villela Marino by alternate Alexandre de Barros; and, the full members Alfredo Egydio Setubal and Ricardo Egydio Setubal for the alternate Paula Lucas Setubal.

CNPJ No. 97.837.181/0001-47 Publicly-Held Company d) Ratification of the remuneration paid to administrators in 2020 and fixing the global budget for 2021 In defining the general parameters of management compensation, the Company takes into account, pursuant to Article 152 of the Brazilian Corporation Law, the values practiced by large companies in different sectors in the market, in line with the strategy of attracting, retaining and encouraging managers in conducting social businesses in order to keep the remuneration package competitive. These values are consistent with the great experience, the responsibilities, the time dedicated to the functions, the competencies and the high degree of the administrators’ commitment with the Company. The Annual and Extraordinary Shareholders' Meeting of April 30, 2020 approved the annual global amount of up to R$ 38.5 million, including social charges, for management compensation in 2020 (Board of Directors and Board of Officers), the Board of Directors being responsible for distribution of this amount among the members of these bodies. However, in 2020, R$ 42.5 million were actually spent (excluding social charges), of which R$ 5.6 million for the members of the Board of Officers and R$ 36.9 million for the members of the Executive Board. The projected global compensation did not include the results obtained in the year 2020, which exceeded the Management's expectations for the year, which is why the payment of profit sharing to the members of the Board of Officers exceeded the target initially provisioned. In view of this, the administration proposes the ratification of the aforementioned amount. In accordance with the guidance contained in the Annual Circular Letter issued by the Securities and Exchange Commission, the General Meeting must set the global annual amount of management compensation taking into account any and all forms of remuneration (fixed and variable), in addition to benefits of any nature, direct and indirect, and representation fees, as well as the amounts paid to the managers based on the stock option plan or other types of stock-based compensation plans. In turn, Official Letter/CVM/SEP/No. 01/2021 presented the understanding of the CVM Collegiate in CVM Proceeding No. 19957.007457/2018-10, in the sense that the employer's social security charges are not covered by the concept “benefit of any kind” (benefício de qualquer natureza) referred to in article 152 of the Brazilian Corporation Law, therefore, they should not include the amounts of global or individual remuneration subject to approval by shareholders at the General Meeting. Thus, for the period from January to December 2021, it is proposed that the Meeting fix the global annual amount of the administrators (Board of Directors and Board of Officers) of up to R$ 48 million, for total remuneration (fixed and variable, comprising benefits of any nature and excluding the social charges of the Company's responsibility), and the Board of Directors is responsible for distributing this amount among the members of these bodies. For the year 2021, management considers the correction of the compensation made to the members of the Board of Directors at the end of 2020, as well as the correction of the compensation for the members of the Board of Officers, the provision of the variable remuneration portion to the Officers at the maximum amount of short-term incentive program and no longer by the target, as well as updating the values of the long-term share-based incentive program. The Management Compensation proposal, as specified in Item 13 of the Reference Form - Attachment 24 of CVM Instruction 480/09, is contained in Attachment 5 to this Manual. ______

EXECUTIVE OFFICERS' COMMENTS

10.1. Executive officers should comment on: a) financial and equity positions in general The comments of the Board of Officers are presented below, which analyze the financial and equity conditions for the years ended on 12.31.2018, 12.31.2019 and 12.31.2020. The balances presented include the new IFRS accounting standard in accordance with CVM Instruction 485/10. The Company's consolidated gross indebtedness presented the following balances at the end of the years of 12.31.2018, 12.31.2019 and 12.31.2020: R$ 2,862.6 million, R$ 2,948.5 million and R$ 3,205.7 million, respectively. The evolution of gross indebtedness in 2020 is mainly linked to the raising of R$ 1.6 billion in the first half of the year as a way of guaranteeing the Company's financial liquidity in the midst of the COVID- 19 crisis. However, it is worth mentioning that the strong cash generation allowed the Company to make a prepayment of R$ 510.0 million as part of the liability management strategy. As investments for maintenance, efficiency gains and capacity expansion projects, R$ 484.3 million, R$ 455.7 million and R$ 487.4 million were invested in the years 2018, 2019 and 2020, respectively. The increase in 2020 was partly due to the consolidation of the results of Cecrisa, acquired in August 2019. The equity, in turn, in the analysis of the administrators, has shown a slight growth over the years: R$ 4,634.9 million, R$ 4,932.2 million and R$ 5,188.4 million, for the periods of 2018, 2019 and 2020, respectively. The relationship between total indebtedness and equity went from 61.7% in 2018 and from 59.8% in 2019, to 61.8% in 2020, within the appropriate parameters in Duratex's capital structure strategy and reinforcing the commitment with financial deleveraging. In 2020, debts were amortized, and interest was paid in the total amount of R$ 1,512.9 million and R$ 1,640.8 million was contracted in new debts. At the end of the period, there was R$ 1,728.4 million in cash, which is higher than the total amount of short- term loans and financing, which totaled R$ 573.4 million, indicating the liquidity capacity to honor commitments with short-term creditors. At the end of 2020, net debt, calculated as short and long-term loans and financing less available cash, was R$ 1,477.3 million, equivalent to 1.2x the Adjusted and Recurring EBITDA (earnings before interest, taxes, depreciation, amortization and depletion), which represents a reduction in financial leverage compared to previous years, which was 1.9x in 2019 and 2.0x in 2018, explained by the strong cash generation and historical operating results of the current period. Management understands that, in a limit situation, this indicator could be raised to 3.5x, without prejudice to the Company's solvency condition and without impacting existing debt contracts. In addition, current liquidity in 2020, given by the ratio of Current Assets to Current Liabilities, totaled 1.7 and indicates the availability in R$ (Reais) to cover each R$ 1.00 of short-term obligations. Regardless of the possibility of financial leverage, the operational performance of the Company's operating segments (wood panels and finishing materials for civil construction) should provide sufficient liquidity to meet short and medium-term requirements, in addition to being sufficient for the implementation of the Company's long-term business plan.

b) capital structure One of the practices in the operational scope is the contracting of credit lines to finance operations. Since August 2010, the Company has an Indebtedness Policy that establishes limits based on indicators based on net debt, which is the result of total indebtedness less available cash. The limit is defined by one of the three alternatives: (i) net debt divided by equity less than 1.0; (ii) net debt divided by Adjusted and Recurring EBITDA less than 3.0 and (iii) short-term net debt divided by Adjusted and Recurring EBITDA less than 0.5. The table below confirms the balanced capital condition, as discussed in the previous item, and compliance with the conditions established in the Policy. (Consolidated in R$ ‘000) 2020 2019 2018 Cash and equivalent 1,728,413 1,243,223 1,162,241 Short-Term debt 573,384 871,865 704,413 Long-Term debt 2,632,337 2,076,675 2,158,191 Total debt 3,205,721 2,948,540 2,862,604 Net debt 1,477,308 1,705,318 1,700,363 Equity 5,188,364 4,932,168 4,634,867 Adjusted and Recurring EBITDA 1,288,306 908,858 848,549 Net debt / Equity 28,5% 34,6% 36,7% Net debt / Adjusted and Recurring EBITDA 1,2 1,9 2,0 Short-term Net debt / Adjusted and Recurring EBITDA Net Cash Net Cash Net Cash Despite the increase in gross debt in relation to the previous year, in 2020 there was a significant reduction in the Company's net indebtedness, still as an effect of the strong cash generation mentioned above. c) payment capability in relation to the financial commitments assumed Duratex's liquidity indicators, as shown in the table below, indicate that the Company has a solvency capacity to meet short, medium and long-term commitments. These indicators showed a significant improvement, suggesting Duratex's financial strength.

Liquidity Ratios 2020 2019 2018 Current Liquidity Ratio 1.7 1.6 1.8 Dry Liquidity Ratio 1.4 1.2 1.4 Quick Liquidity Ratio 0.7 0.6 0.6 General Liquidity Ratio 0.8 0.7 0.9

Likewise, net working capital, resulting from the difference between current assets and current liabilities, had a surplus of R$ 1,808.2 million in relation to short-term obligations in 2020. In 2019, net working capital was R$ 1,364.1 million and in 2018 it was R$ 1,579.3 million. The use of equity and third parties can be found by the ratio between the equity and the total assets. This indicator, which has been decreasing over the years, was 45.1% at the end of the fiscal year 2020, while in 2019 it was 46.0% and in 2018 it was 48.8%, considered thus in line with the results presented.

INCOME STATEMENT Net sales revenue: Despite the impacts resulting from the interruption of economic activities that occurred in periods of the year 2020, the rapid recovery added to the price adjustments led the Company to end the year with net revenue of R$ 5,879.6 million, 17.3% above the same 2019 period. The volume targeting to the foreign market remains strategic for the Company, given that, since the beginning of the year, it has been conquering new markets such as the United States, which led the export revenue to increase by 26.9% compared to 2019, representing 18.0% of the result. The increase of R$ 867.9 million in net revenue, when compared to 2019, is mainly due to: (i) 8.8% increase in revenue in the Deca Division compared to 2019, mainly due to the resumption of demand in the 4th quarter 2020, showing a consistent improvement in the profitability of its products, through the restructuring process implemented based on the Industrial Efficiency and Logistics pillar of its Strategic Growth Agenda, the increase in the volume sold, especially of the Hydra brand, triggered a greater Deca's exposure in markets with lower added value, which partially offset the price increases implemented; (ii) 10.8% increase in the Wood Division compared to 2019, can be justified by the robust strategy of resuming and positioning the Company's products in the market, which, coupled with the strengthening of customer relations, propelled it to present relevant Market Share gains in all product lines, especially in coated products. In the foreign market, despite the strong impact of COVID-19 in Latin American countries, the Company's main markets, the increase in sales to diversified markets and the strategy of strengthening exports, led to a 30% increase in export volumes; (iii) 82.3% growth in revenue from the Ceramic Tiles Division compared to 2019, mainly due to the significant increase in the volume sold and the full incorporation of Cecrisa's revenues in the full calendar year. Changes in the fair value of biological assets: Negative 7.0% change, impacted both by the change in the discount rate to 7.05% compared to the 5.3% used in 2019 and by the effects of the variation in the volume of wood. Cost of products sold: An increase of 7.8% in relation to 2019, mainly due to the higher expenditure on variable expenses due to the significant increase in sales volume, mitigated by the reduction in costs and the record of industrial use, which offset the negative impacts resulting from the temporary suspension of the factories that occurred at the beginning of the second quarter. Selling expenses: Selling expenses increased by 9.1% in the year 2020, compared to the previous year, mainly due to the higher expenditures resulting from the consolidation of Cecrisa in the Company's results. However, these additional expenses were offset by gains in scale in the second half. It is worth mentioning that, despite the negative impacts of COVID-19 on the provision for doubtful debts, the Company's strong control over credit management in line with the improvement of its commercial relations enabled the rapid recovery, ending the year close to normal levels. General and administrative expenses: Increase of R$ 22.7 million, in the year 2020. Duratex directed its efforts in cost reduction projects with the support of a specialized external consultancy, which justified the 10.6% increase in general and administrative expenses of the year. These projects involved a strict review of the production costs, already noted in the improvement of the unit cash cost of the divisions, and of the negotiation process with suppliers, which contributed, for example, to the 45-day increase in the Company's payment term.

The initial uncertainties led to the temporary suspension of trade and services activities and, consequently, the paralysis of part of the industrial sector. Government measures to mitigate impacts on income (such as emergency aid) and employment of the population, in addition to reducing the level of interest rates, ensured that after the process of easing social distance began, in the middle of the year, the recovery economy to happen faster than previously estimated, especially in the construction and home improvement sectors, which also benefited from the impacts of the pandemic on people's consumption habits and lifestyles.

To mitigate the effects of the crisis, Duratex acted, through the creation of the Crisis Committee, directly on 5 fronts: People and Communication; Technology; Industrial/Supplies; Commercial and Finance, which were fundamental to deal with the moment of low demand and also focus on the Company's agility and assertiveness in the recovery process. The speed of its actions combined with the rapid recovery of demand, mainly in the construction and home improvement sectors, led Duratex to achieve the best result in its history for two consecutive quarters, ending the year with a 41.7% growth in its EBITDA Adjusted and Recurring. In the midst of the COVID-19 scenario, the wood panel sector was strongly impacted in the first half of the year, with a drop in volumes both in the domestic market and in exports. However, as the social distance measures began to become more flexible in June, the effect of pent-up demand in the 2nd quarter and the change in market habits resulted in the strong resumption of the sector, ending the year with a 6.5% growth in compared to 2019. The Wood Division started the year 2020 with a performance above expectations, however, due to the strong reduction in demand in the 2nd quarter, it was necessary to temporarily suspend its operations, which strongly impacted its results in this period. However, efficient cost management coupled with rapid repositioning in the market, high quality customer service and a successful price increase strategy, more than compensated for the aforementioned falls, leading the Division to close 2020 with an increase of 38.3% in its Adjusted and Recurring EBITDA. The sector of civil construction materials, in turn, after the sharp drop presented in the first half, showed continuous improvement according to data released by the Brazilian Association of the Construction Materials Industry (Associação Brasileira da Indústria de Materiais de Construção - ABRAMAT), however, this improvement was insufficient to offset the effects of the COVID-19 crisis, leading to a slight retraction in deflated billing of 0.4% in the accumulated result for the year. The year 2020 was challenging for Deca, in the first quarter impacted by the flooding in the metals unit in São Paulo, the Division still suffered a large retraction in demand with the closing of the economy due to the pandemic, which only started showing signs of improves after the stores reopened. However, the Division's agility in adapting to the scenario with the strengthening of commercial actions on different fronts, such as the food channel through the Hydra brand, and the launch of its marketplace, as well as the differentiated marketing actions carried out with customers and the strong resumption of the retirement sector was sufficient to leverage the Division's Adjusted and Recurring EBITDA growth of 25.1% in the year. The Ceramic Tiles market, as well as in the other sectors mentioned, was strongly impacted in the first half of 2020 with the drop in demand. However, despite presenting a later resumption due to the complexity of restarting the furnaces, it ended the year with a 2.5% growth and with the level of industry use at a level higher than that presented in 2019. The Ceramic Tiles Division started the year with the objective of maximizing the capture of synergies between the Ceusa and Portinari brands. With the remodeled administrative and commercial structure, the enhancement of brands and cost reduction ensured that the annual results exceeded the initial estimates. It is worth noting that this result was not only better due to the pandemic scenario, which in addition to the strong loss of demand, included a government decree in which all factories had to temporarily reduce the number of employees by 50.0%, which impacted production directly. With the reopening of the economy, as well as in Deca, the Division had a strong boost, starting to operate at full capacity in the middle of the third quarter, which led to the end of the year with the growth of 63.2% of the Adjusted and Recurring EBITDA compared to 2019.

This revenue comes mainly from the Wood Division, which has a greater participation in the Company's results, and has approximately 25.0% of its revenue in foreign currency. The Deca Division and the Ceramic Tiles Division have around 5.0% and 10.0% of total revenue linked to export, respectively.  Changes in prices: Considering the pricing strategy, Duratex seeks through assertiveness in pricing and better positioning of its products in the market, to ensure the maintenance of its margins at levels higher than its competitors, mitigating the effects of inflation of its production inputs and exchange rate impact.  Volume: Duratex has been focusing its efforts on getting closer to its customers and launching products that are increasingly aligned with market trends, which allows the Company to improve its volumes sold. It is also worth mentioning the important increase in volume in the Ceramic Tiles Division as of August 2019 as a result of the acquisition of Cecrisa. The Company's growth tends to be impacted by the performance of the real estate market, which influences the level of demand for Duratex products in the late construction cycle, that is, on average, 18 months after the real estate launch.

Duratex's cost is mainly affected by inflation, since it is mostly incurred in Reais, with some exceptions as presented in the course of this item. Part of the Company's raw materials for production are linked to international commodities and fixed in foreign currency (dollar), thus subject to the current exchange variation. In the Wood Division, the main commodities are urea and methanol, essential inputs for the manufacture of resin, which corresponds to approximately 20.0% of the cost of the product sold. As a way of protecting against eventual price

CNPJ No. 97.837.181/0001-47 Publicly-Held Company fluctuations in these commodities, the Company has a resin plant in the industrial unit in Agudos (SP), which makes it possible to purchase inputs strategically, thus mitigating the effects of periods of greater volatility. In the Deca Division, on the other hand, the greatest exposure in commodity is linked to basic items such as copper alloy and plastic polymers. The Ceramic Tiles Division has no relevant costs related to commodity inputs. Due to the effects of commodities, as well as other imported inputs, the Company is exposed to exchange rate variation, especially in the Wood Division, with approximately 25.0% of costs pegged to the dollar. In the Deca Division, this exposure is approximately 15.0% and in the Ceramic Tiles Division, it is 5.0%. 2020 2019 2018 Volume Shipped (‘000 m³/year) 2,826,767 2,504,371 2,748,107 Cash Cost (in '000) 1,939,935 1,810,428 1,905,730 Wood Division Unit Cash Cost (in R$/m³) (686.27) (722.91) (693.47) Gross Margin (%) 30.7% 23.7% 28.6% Volume Shipped (‘000 units/year) 27,315 25,730 26,052 Cash Unit Cost (in '000) 1,074,995 1,045,375 1,015,507 Deca Division Unit Cash Cost (in R$/unit) (39.36) (40.63) (38.98) Gross Margin (%) 32.1% 27.4% 24.9% Volume Shipped (sqm) 24,274,772 13,483,484 5,340,125 Ceramic Tiles Cash Cost (in '000) 517,816,000 318,677,000 111,308,000 Division Unit Cash Cost (in R$/sqm) (23.56) (23.63) (20.84) Gross Margin (%) 33.4% 33.1% 39.3%

The new company (LD Celulose), which will operate the plant and the forest, will be owned by Duratex and Lenzing, with a 49.0% and 51.0% interest, respectively. This project was approved in December 2019. In 2019, Duratex acquired 100.0% of the shareholding Cecrisa Revestimentos Cerâmico, one of the main ceramic tile companies in the country, owners of the Cecrisa and Portinari brands. The total amount of the transaction was composed of (i) R$ 264.0 million in cash; (ii) incorporation of net debt in the amount of R$ 442.0 million; (iii) possible additional price of up to R$ 275.0 million in the event of future verification of certain suspensive conditions. This acquisition is in line with Duratex's purpose of offering “Solutions to better live” and represents an important step in expanding the Company's product portfolio. In 2020, Viva Decora Internet Ltda was fully acquired by the Company, which since November/2017, when the Company acquired 28.6% of its shares, had been receiving additional contributions, thus increasing its participation in the business over time. The platform works as an inspiration for interior decoration and renovation, including a base of more than 120,000 registered architects and designers. In addition, it has digital marketing intelligence and an integrated marketplace channel, being the leader in accesses, with organic traffic of more than 10.0 million sessions per month. The acquisition was an important step in Duratex's long-term strategy, which, together with the launch of Deca's marketplace, seeks to strengthen contact with partners and end consumers, combining technology and innovation through the enhancement of digital channels, in addition to following the trend of intensified online buying amid the COVID-19 pandemic. c) unusual events or operations On January 31, 2018, the Company sold facilities and equipment for the production of thin wood fiber sheets in transaction with the Eucatex Group. The transaction involved exchanging these facilities and equipment for a farm, located in the municipality of Capão Bonito (SP), a strategic region due to the proximity to the Itapetininga wood panel unit, based on the amount of R$ 60.0 million. On February 5, 2018, Duratex sold 30.0 thousand hectares of land and forests in the central region of the State of São Paulo in a transaction with Suzano Papel e Celulose for approximately R$ 1.0 billion. The operation was carried out in two stages, the first being the sale of approximately 9,500 hectares of rural areas and the forest assets in them, in the amount of R$ 308.1 million. And the second, concluded on July 2, 2018, involved the sale of approximately 20.0 thousand hectares of rural areas and the forest assets existing there, totaling R$ 749.4 million. This operation was made possible due to the Company's higher forest productivity over the years, which led the company to have a forest base that exceeded the planned needs of its wood panel factories. On July 23, 2018, the Company announced investments of R$ 94.0 million for the expansion of the ceramic tile unit, increasing the total production capacity to 11.0 million m2 per year, which represented an increase of 83.0%. On November 1, 2018, Duratex announced the end of the industrial operation for the production of electric showers in Tubarão (SC) and the transfer of the production lines to Aracaju (SE), with no impact on installed capacity.

10.5. Executive officers should indicate and comment on the critical accounting policies adopted by the issuer, in particular, the accounting estimates made by management on uncertain and relevant issues for describing the financial position and results that require subjective or complex judgment, such as: provisions, contingencies, revenue recognition, tax assets, long-lived assets, useful lives of non-current assets, pension plans, foreign currency translation adjustments, environmental recovery costs, criteria for asset and financial instrument impairment tests Estimates and critical accounting judgments In the preparation of the financial statements, judgments, estimates and accounting assumptions were used to account for certain assets and liabilities and other transactions. The definition of accounting estimates and judgments adopted by Management was prepared using the information available on the date, involving experience of past events and forecast of future events. The financial statements include various estimates such as: useful lives of property, plant and equipment, realization of deferred tax credits, impairment of accounts receivable from customers, losses on inventories, assessment of the fair value of biological assets and provision for contingencies, impairment test goodwill, pension plan and health benefits, among others. The main estimates and assumptions that may present risk, with a probability of causing adjustments in the book values of assets and liabilities, are contemplated below: a) Risk of fair value variation in biological assets The Group adopted several estimates to assess its forest reserves in accordance with the methodology established by CPC 29 / IAS 41 - “Biological assets and agricultural product". These estimates were based on market references, which are subject to changes in the scenario that may impacting the financial statements in this sense, a 5% drop in market prices for standing timber would cause a reduction in the fair value of biological assets of approximately R$ 33.8 million, net of tax effects. An increase of 0.5% in the discount rate, would cause a reduction in the fair value of biological assets in the order of R $ 6.0 million, net of tax effects. b) Estimated loss (impairment) of goodwill The Company and its subsidiaries test annually or if there is any indication at any time, any losses on goodwill, in accordance with the accounting policy presented in notes 2.10 and 2.12. The balance may be impacted by changes in the economic or market scenario. c) Pension plans and health insurance benefits The current value of assets/liabilities related to pension and health plans depends on a series of factors that are determined based on actuarial calculations, which use a series of assumptions. Among these assumptions used in determining values is the discount rate and current market conditions. Any changes in these assumptions will affect the corresponding book values. d) Contingencies The Group establishes a provision for tax, labor, civil and social security contingencies based on the assessment of the likelihood of loss that is made by its legal advisors. The amounts recorded are updated and the Group's Management believes that the provisions made up to the closing date are sufficient to cover possible losses from legal and administrative proceedings in progress.

CNPJ No. 97.837.181/0001-47 Publicly-Held Company e) Fair value of financial instruments When the fair value of financial assets and liabilities presented in the balance sheet cannot be obtained from active markets, it is determined using valuation techniques, including the discounted cash flow method. The data for these methods are based on those practiced in the market, when possible; however, when this is not feasible, a certain level of judgment is required to establish fair value. The judgment includes considerations on the data used, such as, for example, liquidity risk, credit risk and volatility. Changes in assumptions about these factors could affect the fair value presented for financial instruments. f) Deferred income tax and social contribution The Group records deferred income tax and social contribution assets on tax losses and negative social contribution bases and temporary differences. The recognition of these assets takes into account the expectation of generating future taxable profits. Estimates of future results that will allow the offsetting of these assets are based on Management's projections, which are reviewed and approved by the Board of Directors, taking into account economic scenarios, discount rates, and other variables that may not be realized.

In addition, the collections with localized metal made in digital printing were also responsible for the impact of differentiation of the new products on the market, in addition to the colored monoporous providing new concepts of composition. In the second half of the year, the brand brought a line of 24 products with complementary appeal to Revestir's launches, offering collections of bases with different textures and formats in the same visual pattern, ensuring versatility and functionality to the new portfolio. Portinari already carried out two major product launches. The first at Expo Revestir, where it presented 175 unpublished products, with emphasis on the collection signed by the architect Marília Zimmermann. The collection with a very wide color palette brought a new format to the portfolio with diamond pieces. In the second half, Portinari launched 99 products at Cersaie - Italy. To present the launches to Brazilian customers and specifiers, a preview was made in Brazil, at Galeria Cerâmica Portinari, in São Paulo. Highlight for the porcelain tiles with wood-like finish with the new 20x160 cm format and for the longilinear bricks in the 5x40 cm format. In total, 274 products were launched by the brand in 2019, with the highest technology and sensitivity in details. In 2020, the Ceusa and Portinari brands consolidated the process of synergy and integration of their internal product development and launch processes. At the same time, they reinforced their individual identities through the launch of products capable of promoting the perception of value of each of the brands. Therefore, two distinct processes were developed: from the point of view of internal functioning, the synergies plan was consolidated and, from the external point of view - from the perception of customers - there was a deepening in the distinction and positioning of each brand. The Ceusa and Portinari brands ended 2020 with their portfolios containing 519 and 1,225 stock keeping units (SKU’s) of their own production, respectively, totaling 1,744 products. There was a rationalization process in which 30.0% of the product portfolio was reduced during the year. Of the total of 1,744 products, 234 are products launched in 2020. The launch took place in March at the Revestir fair, where Ceusa launched 87 SKU’s and Portinari 147 SKU’s. The launches focused on large formats (120x120 cm, 100x100 cm, 80x160 cm, 60x120 cm, 90x90 cm) with high added value and a high perception of innovation, with positive consequences both in obtaining results and in positioning the brands. Ceusa translates into its products the lightness of happiness, youthful joy, the intensity of colors and textures. Of the 2020 launches, we highlight the products Confetti, Pétalas, Cascais and Óptico. Portinari with elegant and sophisticated products is linked to sensitivity and art. We highlight the Nuances da

13.1. Describe the remuneration policy or practice of the board of directors, of the statutory and non- statutory board, of the fiscal council, of the statutory and audit committee, of risk, financial and of remuneration, addressing the following aspects: a. objectives of the remuneration policy or practice, informing if the remuneration policy was formally approved, administrative body responsible for the approval, date of the approval and, in case the issuer discloses the policy, places on the worldwide computer network where the document can be found The remuneration practice of the Company aims to attract, retain and engage the better professionals enabling, thus, the Company to reach a higher performance. The remuneration is established and updated according to market researches that consider large companies and various sectors, in order to maintain the remuneration package competitive. In the case of the Company’s Statutory Board, the remuneration package contemplates variable payment besides the monthly wages, what enables its members to share the risks relative to the business management and its results, allowing, therefore, for further alignment of interests between the Company´s management and shareholders, in a joint effort to ensure its continuity. In the Advisory Committees for the Board of Directors only the presidents and specialists are remunerated and the amount spent is taken into consideration in the overall annual budget of the Board of Directors approved in the General Meeting of Shareholders. b. composition of the remuneration, indicating: i. description of the remuneration elements and the purpose of each of them Fixed remuneration: Fixed remuneration is defined by the monthly amount paid as fees to remunerate management of Duratex for the positions held. The amounts paid as fees are usually aligned with the market´s average, allowing thus the Company to direct significant part of the total remuneration to the short- and long-term variable incentives. Eligibility: Members of the Board of Directors and of the Company´s Statutory Board, as well as presidents and specialists of the Advisory Committees for the Board of Directors. Variable remuneration: Consists of Short-Term Incentives and Long-Term Incentives (Stock Option Granting Plan, of August/2009 to December/2019, and the Long-Term Incentive Plan, from 2020 on). The purpose of the Short-Term Incentives is to recognize and reward the members of the Statutory Board for the year’s achievements (twelve (12) month period), encouraging them to achieve and overcome goals and results, according to individual performance, of the respective department, and of the company´s overall performance. According to the Long-Term Incentives Regulation approved in the General Meeting of the Shareholders of 04.26.2019 (new ILP Plan), effective as of 2020, which replaces the Stock Option Granting Plan, approved in the General Meeting of the Shareholders of 08.31.2009, and amended on 04.25.2012 (Option Plan), part of the Short-Term Incentives may be invested by the eligible participant/beneficiary of the “Matching” incentive according to the established terms.

Eligibility: Statutory Board The purpose of the Long-Term Incentives, paid in accordance to the new ILP Plan, is to recognize and reward the members of the Statutory Board for the results obtained in periods of over one (01) year, integrating them in the Company’s development on the medium and long term, and allowing them to participate in the increase in value that their work and dedication brought to the shares issued by Duratex. The variable payment will contemplate, starting from the fiscal year of 2020, the incentives of Performance Shares and Matching provided by the new ILP Plan’s regulation, being that the management’s total remuneration in order to place the eligible in the company’s strategies of P75 of the market, will be able to represent around 25% of the total remuneration package. Since the new ILP Plan’s regulation is effective from the fiscal year of 2020, it’s important to highlight that the Option Plan is still contemplated and referenced as a Long-Term Incentive up to the fiscal year of 2019, as a result of the active grants as we will verify below. Benefits: Duratex’s remuneration package is further composed of a set of benefits that aim to improve the quality of life and provide management and their legal dependents adequate healthcare, supplementary retirement pension and life insurance group plans. Eligibility: members of the Board of Directors (except the independents) and members of the Statutory Board. It’s important to emphasize that Duratex has, within the scope of the Board of Directors, the Persons, Governance and Nomination Committee, that assesses the strategy and remuneration to be adopted for recruiting, retaining, and engaging of new professionals, and which, subsequently, is approved by the Board of Directors. ii. regarding the last three (3) fiscal years, what is the proportion of each element in the total remuneration

Pág. 82

CNPJ No. 97.837.181/0001-47 Publicly-Held Company iii. calculation and adjustment methodology of each of the remuneration elements The remuneration values paid by Duratex to its management are defined according to the importance and relative weight of the position in the corporate structure and the positioning strategy before the market. The adjustment occurs periodically, if applicable, after undertaking remuneration research carried out annually by companies specialized in the subject, through which the practiced values are compared by Duratex to the market and measured the level of competitiveness and necessity of adjustments to the amounts practiced. These researches cover all of the remuneration elements. iv. reasons that justify the composition of the remuneration Duratex seeks through the current composition of the remuneration to provide market attractiveness, retention, and the engagement of professionals relative to continuity and value creation for the Company. It, therefore, adopts a model that links recognition and reward to the achievement of significant results for the business. v. The existence of non-remunerated members by the issuer and the reason to this fact Not applicable. c. main performance indicators that are taken into consideration in determining each element of the remuneration The main performance indicators are linked to the Company’s financial results, EBITDA and Free Cash Flow, in addition to specific projects and goals of each business area, and to a set of individual goals of each administrator, regarding the target agreement model. d. how the remuneration is structured to reflect the development of the performance indicators The fixed remuneration payment may be altered by merit of the administrator and/or by misalignment in relation to the market, demonstrated by researches carried out annually, and performance evaluation of the period. Such modification must be proposed by the Persons, Governance and Nomination Committee and approved by the Board of Directors. In terms of the variable remuneration payment, it is fully associated to the achievement of defined goals for the twelve (12) months period, being bigger or smaller according to the degree of achievement or of the overcoming of these goals. It is worth mentioning that, following the market’s evolution and the Company’s interests, the goals associated to the variable remuneration may be linked to environmental and social issues, and to levels of governance, aligned to the strategy defined by the Company’s management. e. how the policy or practice of remuneration aligns to the interests of the short-, medium-, and long- term issuer The composition of the remuneration defined for the management of Duratex is aligned to the short-, medium-, and long-term interests, being that the fixed remuneration reflects the market’s average remuneration, and the variable payments suffer direct impact from the short-term (period of twelve (12) months) and the long-term (periods over one (01) year) results.

In this manner, a tree was drawn with the price tracks so that the share value could be determined in a future date, based on the volatility defined and on the timeframe on the tree from the moment of pricing up to date of expiry. The pricing process of this model was made through the Backward Induction method, starting from expiry up to the starting point. For the Performance Shares and Matchings plans, the detailed information can be found in item 13.4. b. data and premises used in the pricing model, including average price of the shares, exercise price, expected volatility, timeframe until the expiry of the option, expected dividends, and interest rate free of risk The binomial pricing model used in the Shares Options Granting Plan took under consideration the price of the asset-object, exercise price, volatility, return rate of the dividends, free of risk rate, grace period, timeframe until the expiry of the option, all as premises for pricing. Please find the description of the premises used:  Price of the Asset-Object: the price of the Duratex shares (DTEX3) used in the calculation was the closing price at B3;  Exercise Price: as the exercise price of the option, the previously defined exercise price at the time of the issuance was used, with monetary update made based on the IGP-M variation;  Expected Volatility: calculated based on the standard deviation history of the last 365 daily feedbacks of the DTEX3 share closings, published by B3, with monetary update made based on the IGP-M variation;  Dividends Rate: 2% rate was used;

Up to the end of the grace period, the exercise of the option was not permitted. The grace period was defined at the moment the series of options were issued. Since the end of the grace period, the option could be exercised at any moment until the end of the fixed effective timeframe. The pricing of the options made through the binomial tree took under consideration their grace period. Not applicable to the Performance Shares and Matching plans. d. form of establishing the expected volatility Expected volatility: calculated based on the standard deviation history of the last 365 feedbacks of the daily DTEX3 share closings prices, with monetary update based on the IGP-M.

REGULATION OF THE LONG-TERM INCENTIVES PLAN

I – OBJECTIVE OF THE PLAN 1.1 The present Long-Term Incentives Plan (ILP Plan) of the Duratex Corporation and of its controlled companies (“Duratex” or solely “Company”) aims at: i) Stimulating the commitment of Duratex’s officers in the long-term, in a manner to encourage that they seek success in all their activities and achieving Duratex’s objectives; ii) Attracting and retaining the best professionals by offering incentives that are aligned with the continuous growth of Duratex; and iii) Giving Duratex, in what concerns variable remuneration, a competitive edge in comparison to the rest of the market. 1.2 The plan is structured in a way to incentivize the Participants to contribute to Duratex’s achievements, since they will become Shareholders of the Company and will be directly rewarded by the appreciation in the price of the respective shares. Therefore, the alignment of interests of the Shareholders of Duratex with that of the Participants is a way to reach the main objectives of the Plan, which are: (i) growth; (ii) achievement; (iii) success; and (iv) accomplishment of Duratex’s objectives.

II – MANAGEMENT OF THE PLAN 2.1 The plan will be managed by the Remuneration Department of the Human Resources Office of Duratex, observing the terms and conditions herein established. It will be up to the Board of Directors of the Company to, after hearing the Persons, Governance and Naming Committee (“Committee”), deliberate annually about the application or not of the Plan, defining who will be the Participants, as well as which Participants should be temporarily or permanently suspended from the Plan.

2.2 This Plan will be in effect starting on 2020, in substitution of the granting of stock options plan.

III – CRITERIA OF THE PLAN 3.1 In the application of the ILP Plan the following criteria will be abided by for the incentives: a) Performance shares In the field of the Performance Plan, issuance shares of Duratex will be transferred to the Participants when reaching the performance target, based on Duratex’s strategic planning for a five (5) year period. The Performance target will be defined by the Duratex Committee annually and will be approved by the Board of Directors. To receive the shares, a five (5) year grace period shall be observed and the Participant must continue in Duratex. The amount of shares will have as price reference the average of the last thirty (30) trading floor sessions.

In case of termination without fair cause or of non-reappointment to the position from the 37th month on, the Participant will receive, after the period of five (5) years, shares proportional to the period worked therein. Voluntary termination will result in the loss of right to the shares irrespective of the timeframe passed. The Performance Plan will be applicable only to officers (“Statutory and non-Statutory"). b) Matching Duratex will invite the Beneficiary to invest a percentage of its net ICP (short-term incentive) buying shares of the Company. The Matching of the shares will be done in the following manner: (i) completing four (4) years of investment, Duratex will proceed with the transference of 50% of the shares to the Beneficiary and only the transferred shares will be able to be commercialized by the Beneficiary; and (ii) completing five (5) years of investment, Duratex will complete the pay in of 100% of the Matching through the transference of the remaining 50% of the shares to the Beneficiary. To be entitled to the complete Matching, the Beneficiary cannot commercialize the shares it bought on the moment of the investment until after the five (5) year grace period, that is, in case the Beneficiary sells his/her shares before the five (5) year period he/she will lose the right to Matching. The transference is conditioned to the Beneficiary staying at Duratex and to maintaining the investment made in the purchase of the shares. In case of termination without fair cause or non-reappointment to the position from the 13th month of the granting on, the Participant will have the right to Matching pro rata temporis to be settled at the end of the five (5) year period. Voluntary termination will result in the loss of right to Matching. The Matching Plan will be applicable only to officers (“Statutory and non-Statutory"). c) Restricted Shares Duratex shares will be transferred to its employees, without cost, if the terms and conditions herein established are met. The Board of Directors, after hearing the Chief Executive Officer of Duratex, will grant in a discretionary manner shares to the Participants that in the period of one (1) year had a differentiated performance and generated high impact to Duratex`s business. The referred granting will obey: (i) criteria to create a pool of eligible individuals; (ii) talent database; (iii) consistent achievement of individual targets; and (iv) potential evaluation. The shares will be transferred after the period of three (3) years from the granting. In case of termination without fair cause from the 13th month of the granting on, the Participant will have the right to Matching pro rata temporis to be settled at the end of the 3rd year. The Beneficiary voluntarily leaving the Company, he/she will lose the right to the shares irrespective of the timeframe passed. This Plan category will be applicable to employees (“employees”) hired under the Consolidated Labor Law (“CLT”) regime.

6.6 Occurring termination with fair cause or destitution of the position or non-reelection of the Participant, as foreseen in items “a” and “b”, for a reason that Duratex understands equitable to fair cause for termination, it will result in the loss of the right to the ILP. 6.7 In the case of permanent invalidity, the complete transfer of the Duratex shares will be made to the Beneficiary on the act of the event. 6.8 In the case of death of the Beneficiary, the shares will only be transferred in its entirety when the judicial decision or public deed of the extrajudicial sharing of assets is presented, defining the heirs to the Beneficiary that will have the right to receive the shares. 6.9 In the cases of termination without fair cause where the Beneficiary is retired, the Board of Directors will analyze and decided for the transfer of the shares or not to the Beneficiary, as well as the amount and period in which it will be undertaken.

VII – GENERAL CONDITIONS 7.1 None of the Participants will have any rights or privileges of Duratex shareholders, including in relation to dividends until the granted shares are handed over and the registration in the name of the Participant is duly made. 7.2 In case modification to Duratex`s share structure occurs, involving unfolding, grouping, or bonification of shares, the Human Resources Office, through its Remuneration Department, will make the necessary adjustments in the number of Duratex`s ordinary issuance shares attributed to the Participants that are in the grace period established in the ILP Plan, as well as in the agreements made with them. 7.3 Possible taxes incurring and resulting from the Plan will be the liability of each party determined in the applicable legislation. 7.4 The provisions contained in the present ILP Plan are effective immediately after its approval, however, it will depend on the annual deliberation of the Board of Directors. 7.5 The Board of Directors, in the interest of Duratex and of its shareholders, may, at any time, suspend definitely or indefinitely the application of the present ILP Plan, any legislative modification to the regulation of corporations or of their fiscal effects that significantly affect the present ILP Plan may lead to its partial or complete revision, or even to its suspension or termination. 7.6 No provision of the present ILP Plan shall grant rights to the Participants concerning guarantee of their position or continuance and/or reelection of their position, neither will it interfere in Duratex`s right to terminate/destitute, according to the applicable to each case, the relationship with any Participant at any time. 7.7 Omissions will be regulated by the Board of Directors. ______
