Free Translation of the Letter n. 74/2018/CVM/SEP/GEA-2 send by the Brazilian Stock Exchange Commission (CVM). Letter n 74/2018/CVM/SEP/GEA-2 Rio de Janeiro, March 8, 2018 To Mr. GUILHERME PERBOYRE CAVALCANTI Investors Relations Officer of FIBRIA CELULOSE S.A. Rua Fidêncio Ramos, 302, Torre B, 3º e 4º andares - Vila Olímpia 04551-010 São Paulo - SP Tel.: (11) 2138-4565 Fax: (11) 2138-4066 E-mail: ir@fibria.com.br With a copy to: emissores@b3.com.br; ana.pereira@b3.com.br; maiara.madureira@b3.com.br; marcelo.heliodorio@b3.com.br; nelson.ortega@b3.com.br Matter: Request of clarification about news conveyed on media Dear Mr. Officer, 1. We refer to the news conveyed on the Valor Econômico news and Infomoney, a worldwide web portal on March 5, 2018, entitled “Suzano and Fibria are close to announce a merger, sources say” and “Fibria and Suzano jump 5% after news inform that companies are close to a merger; 7 companies react to balance sheets”, in which the following information is stated: Suzano and Fibria are close to announce a merger, sources say By Ivo Ribeiro, Stella Fontes and Francisco Goés SÃO PAULO AND RIO (Updated at 12h11) Suzano Papel e Celulose and Fibria, the two world biggest eucalyptus pulp producers, are close to announce an agreement to combine its assets. The final format of the transaction is yet under discussion, but one of the defined assumptions is the exit of Votorantim of the business and the control of the new entity taken by Suzano, according to sources of the market. Shareholder of both, the Social and Economic Development National Bank (BNDES) shall keep a material shareholding participation on the new entity. Through its shareholding investment arm, the BNDESPar, the bank has 29,08% of Fibria and 6,86% of Suzano. In an interview to Valor, BNDES’ President, Paulo Rabello de Castro, has confirmed the discussions. Suzano speeds us to bind an agreement to by Fibria soon, due to the possibility that others interested parties – foreign competitors – could present aggressively binding proposals, ascertain Valor.

One of the biggest challenge at this moment is to conciliate the interests of buyers and sellers. Suzano looks for to reduce to the minimum possible the disbursement of resources in the transaction. At its turn, Votorantim has the intention to sell all of its shareholding at once. According to Fibria’s by-laws, in case Votorantim sells the 29,42% that holds in the company, the buyer will have to extend the offer to all the shareholders of the company. This will raise the amount of the transaction, considering the market prices, to something around US$ 10 billion, after discounting the net debt. Valor ascertained that an alternative to avoid the public acquisition offer (OPA), required in case of acquisition of 25% or more of Fibria’s shares, is that Votorantim receives a cash payment for up to 24,9% of its shareholding. And change the remaining 4,52% by shared of the new entity, remaining for a certain period as minority or as an investor. Further, Votorantim could sell these shares in the market. For this model prevail, it is also necessary the endorsement of BNDES and contemplate the internal concerns of the bank. BNDES would receive shares of the new entity in exchange of the 29,08% that holds on Fibria and the 6,68% on Suzano. According to sources, inside the public bank there is a group that defends the maintenance of the shareholding on the company resulted of the acquisition of Fibria by Suzano. Another defends that this is the time to monetize the investment made years ago by the bank in this sector and defends the sale of the shares at a good time for prices in the stock exchange. There is a dedicated team inside the bank to work on this matter. BNDES decision involves yet another strategic factor, according to market sources. Besides Suzano, there are others interested in Fibria and at least one of them, Paper Excellence (PE), would be looking into financing to offer 100% of Ermirio de Moraes pulp producer. With this, there is a risk of another company in this sector, and the greatest of them, going to foreign capital hands. The Indonesian PE has not hesitated in offering R$ 15 billion by Eldorado Brasil last September, from J&F Investmentos, removing many interested companies, including Fibria. According to the sources consulted by Valor, the controlling families of Suzano and Fibria understand that the most interesting operation passes by the combination of the two companies’ assets. However, other offers will not be ignored. Votorantim and Suzano were consulted by Valor and have not commented this subject. “In the face” Paulo Rabello de Castro has confirmed to Valor that the bank is discussing with Fibria’s and Suzano Papel e Celulose’s representatives about the possible merger between these two companies. According to BNDES’ President, there is a negotiation in course between these two companies and, in this discussion, the bank has had an active position. “We have discussed and we are integrated in this work that it is joining these two giants [of pulp and paper sector]”, said. Questioned about whether the discussions appoint to the possibility of a merger between Suzano and Fibria, Rabello de Castro answered: “It is in the face [obviously] that a merger is a possibility, but we are in a moment that nothing more can be said.”

Fibria and Suzano jump 5% of news inform that companies are close to a merger; 7 companies react to balance sheets. Lara Rizério Fibria (FIBR3) and Suzano (SUZB3) The shares of Fibria and Suzano soared at this session, after Valor Econômico advertises that the two world biggest eucalyptus pulp producer are close to announce an agreement to combine its assets. According to the news, the final format of the operation is yet in discussion, but one of the assumptions already defined is the exit of Votorantim of this business and the control of the new entity taken by Suzano, according to sources consulted by the news. According to sources consulted by the news, the controlling families of Suzano and Fibria understand that the most interesting operation passes by the combination of the two companies’ assets. However, other offers will not be ignored. Still in the companies’ radar, Fibria announces a new increase of the pulp price, from US$ 20 per ton to Europe and North America, and US$ 10 per ton to Asia, valid from 1st of April. Therefore, the new prices per region will be: US$ 1.050 per ton in Europe, US$ 1.230 per ton in North America and US$ 840 per ton in Asia. 2.
