The registrant’s forward-looking statements are based on the registrant’s current expectations, assumptions, estimates and projections about the registrant and its industry. These forward-looking statements can be identified by words or phrases such as “anticipate,” “believe,” “continue,” “estimate,” “expect,” “intend,” “is/are likely to,” “may,” “plan,” “should,” “would,” or other similar expressions.

The forward-looking statements included in the attached relate to, among others: (i) the registrant’s business prospects and future results of operations; (ii) weather and other natural phenomena; (iii) developments in, or changes to, the laws, regulations and governmental policies governing the registrant’s business, including limitations on ownership of farmland by foreign entities in certain jurisdictions in which the registrant operate, environmental laws and regulations; (iv) the implementation of the registrant’s business strategy, and current projects; (v) the registrant’s plans relating to acquisitions, joint ventures, strategic alliances or divestitures; (vi) the implementation of the registrant’s financing strategy and capital expenditure plan; (vii) the maintenance of the registrant’s relationships with customers; (viii) the competitive nature of the industries in which the registrant operates; (ix) the cost and availability of financing; (x) future demand for the commodities the registrant produces; (xi) international prices for commodities; (xii) the condition of the registrant’s land holdings; (xiii) the development of the logistics and infrastructure for transportation of the registrant’s products in the countries where it operates; (xiv) the performance of the South American and world economies; and (xv) the relative value of the Brazilian Real, the Argentine Peso, and the Uruguayan Peso compared to other currencies; as well as other risks included in the registrant’s other filings and submissions with the United States Securities and Exchange Commission.

These forward-looking statements involve various risks and uncertainties.
