3. Projected period and projection expiration date

Synergies

With respect to operational synergies, the projected period comprises the fiscal years of 2019, 2020 and 2021, and the Company expects to achieve 40% of these operational synergies on December 31, 2019, 90% on December 31, 2020 and 100% on December 31, 2021.

Regarding specifically tax synergies, the projected period comprises the fiscal years of 2019, 2020 and 2021. However, the Company estimates that this synergy will continue until the end of the fiscal year of 2029, from the merger of Fibria into Suzano.

The abovementioned projections, whose seizures will occur gradually, are valid until the end of the aforementioned periods, highlighting potential changes in this estimate due to advancements in the integration process between the Company and Fibria and premises will be disclosed to the market under the terms of applicable legislation.

CAPEX

The CAPEX guidance refers to the fiscal year of 2019, as reflected in the CAPEX budget for the period, so that the expiry of such guidance extends until December 31, 2019.

4. Premises and metrics for projection estimation

Synergies

The seizure of expected synergies is based on the premise that the Company will be able to successfully implement the following initiatives, among others:

· Production optimization per factory;

· Cost reduction of industrial, forestry and fuel inputs used in its operations;

· Optimization of the forest base and, hence, the supply of wood for industrial activity;

· Logistic optimization of wood supply and product outflow;

· Equalization of contractual parameters; and

· Adjustments in organizational and administrative structure.

The synergies projections with the aforementioned reduction of costs, expenses and capital investments were based on budgets and studies prepared by the Company internally with the support of external consultants and advisors and whose foundation was the implementation in the Company of the best practices that were identified during the evaluation and integration process of Suzano with Fibria.

CAPEX

For the purposes of the 2019 CAPEX guidance, were assumed as premises both the Company’s and Fibria’s 2018 CAPEX, maintaining the stable trend of the sustaining CAPEX, the remaining investments in projects previously disclosed to the market and potential new investments in lands and forests as natural course of the Company’s business.
