About SQM

SQM´s business strategy is to be a global company, with people committed to excellence, dedicated to the extraction of minerals and selectively integrated in the production and sale of products for the industries essential for human development (e.g. food, health, technology). This strategy was built on the following five principles:

• ensure availability of key resources required to support current goals and medium and long-term growth of the business;

• consolidate a culture of lean operations (M1 excellence) through the entire organization, including operations, sales and support areas;

• significantly increase nitrate sales in all its applications and ensure consistency with iodine commercial strategy;

• maximize the margins of each business line through appropriate pricing strategy;

• successfully develop and implement all lithium expansion projects of the Company, acquire more lithium and potassium assets to generate a competitive portfolio.

These principles are based on the following key concepts:

• strengthen the organizational structure to supports the development of the Company's strategic plan, focusing on the development of critical capabilities and the application of the corporate values of Excellence, Integrity and Safety;

• develop a robust risk control and mitigation process to actively manage business risk;

Cautionary Note Regarding Forward-Looking Statements

This news release contains “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation Reform Act of 1995. Forward-looking statements can be identified by words such as: “anticipate,” “plan,” “believe,” “estimate,” “expect,” “strategy,” “should,” “will” and similar references to future periods. Examples of forward-looking statements include, among others, statements we make concerning the Company’s business outlook, future economic performance, anticipated profitability, revenues, expenses, or other financial items, anticipated cost synergies and product or service line growth.

Forward-looking statements are neither historical facts nor assurances of future performance. Instead, they are estimates that reflect the best judgment of SQM management based on currently available information. Because forward-looking statements relate to the future, they involve a number of risks, uncertainties and other factors that are outside of our control and could cause actual results to differ materially from those stated in such statements. Therefore, you should not rely on any of these forward-looking statements. Readers are referred to the documents filed by SQM with the United States Securities and Exchange Commission, specifically the most recent annual report on Form 20-F, which identifies important risk factors that could cause actual results to differ from those contained in the forward-looking statements.
