About SQM

SQM is an integrated producer and distributor of lithium, iodine, specialty plant nutrients, potassium-related fertilizers and industrial chemicals. Its products are based on the development of high quality natural resources that allow the Company to be a leader in costs, supported by a specialized international network with sales in over 110 countries.

SQM´s business strategy is to be a mining operator that selectively integrates the production and sales of products to industries essential for human development, such as food, health and technology. The strategy is built on the following six principles:

| • | strengthen internal processes to ensure access to key resources required for the sustainability of the business;

| • | extend lean operations (M1) to the entire organization to strengthen our cost position, increase quality and ensure safety;

| • | invest in the development of a specialty fertilizer market, including product differentiation, sales channel management and price optimization;

| • | recover the iodine market share, seek consolidation and vertical integration opportunities; invest in the development of industrial nitrate applications;

| • | search and invest in lithium and potassium assets outside of Chile to leverage our operational capabilities, take advantage of the current lithium market appeal and ensure access to raw materials for our potassium nitrate production; and

| • | seek diversification opportunities in gold, copper and zinc projects in the region to leverage our mining operating capabilities and provide business continuity to our exploration program.

The business strategy´s principles are based on the following four concepts:

| • | build an organization with strategic clarity, inspirational leaders, responsible personnel and strong values;

| • | develop a strategic planning process that responds to the needs of our customers and market trends, while ensuring coordination between all segments of the business, including sales and operations;

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

| • | improve our stakeholder management to establish links with the community and communicate to Chile and worldwide our contribution to industries essential for human development.
