Santiago, Chile. October 30, 2018.- Sociedad Química y Minera de Chile S.A. (SQM) (NYSE: SQM; Santiago Stock Exchange: SQM-B, SQM-A) announced a structural reorganization, as a part of the Company’s strategic development.

SQM’s Chief Executive Officer, Patricio de Solminihac, stated, “The challenges SQM faces are dynamic, and as a result we need to make changes to the organization. We are currently facing particularly attractive and complex challenges in the production, sales and marketing of lithium, in the production of lithium in both Chile and Australia, and in the production, sales and marketing of nitrates, potassium and iodine. All of these businesses complement and enhance each other, and strengthening our leadership in our five business lines, will allow us to remain a world leader.”

He continued by saying, “We have designed a new corporate structure that will allow us to more effectively focus our efforts on the priorities of our business. The executives that have been placed in charge of each of these departments all have a proven track record of success with SQM. I am confident that the great team we have will be able to successfully lead SQM into the future, while focusing on our values of excellence, safety and integrity.”

Ricardo Ramos will be appointed as Deputy CEO, reporting to the CEO, until January 7, 2019 when he becomes the CEO of SQM.

These changes become effective as of today.
