This presentation contains statements that may constitute “forward-looking statements”, based on current

opinions, expectations and projections about future events. Such statements are also based on

assumptions and analysis made by Wilson Sons and are subject to market conditions which are beyond the

Company’s control.

Important factors which may lead to significant differences between real results and these forward-looking

statements are: national and international economic conditions; technology; financial market conditions;

uncertainties regarding results in the Company’s future operations, its plans, objectives, expectations,

intentions; and other factors described in the section entitled "Risk Factors“, available in the Company’s

Prospectus, filed with the Brazilian Securities and Exchange Commission (CVM).

The Company’s operating and financial results, as presented on the following slides, were prepared in

conformity with International Financial Reporting Standards (IFRS), except as otherwise expressly

indicated. An independent auditors’ review report is an integral part of the Company’s condensed

consolidated financial statements.
