Santiago, Chile. June 6, 2018.- Sociedad Química y Minera de Chile S.A. (SQM) (NYSE: SQM; Santiago Stock Exchange: SQM-B, SQM-A) informs that in relation to the diverse information circulating in the media, SQM considers it necessary to clarify the following:

The agreements reached between SQM and CORFO are significantly more demanding than the agreements that CORFO previously reached with the other lithium producer in Chile: Albemarle. SQM did not have, and has not had, privileges of any kind in its negotiations with CORFO.

The payments that SQM makes to CORFO, as a consequence of the agreements, are based on the prices and sales volumes of the different products. The costs and expenses of SQM do not affect payments to CORFO.

If we consider the prices of the first quarter of 2018, the payments that SQM must make, as a consequence of the agreement with CORFO, for the production and sale of the various lithium products during the second quarter of this year, more than quadruple the previous payments and will represent more than 50% of the gross profit that SQM expects to obtain for these products. The foregoing without considering the taxes that both SQM and its employees and contractors must pay to the State of Chile.

All lithium chemical products produced in Chile are, in percentage terms, one of the natural resources (taking into consideration all natural resources) that provides the most taxes and royalties to the State worldwide.

As a result of the new agreements, SQM has announced investments in Chile for more than US$500 million that will increase sales volumes of chemical products derived from lithium, adding value to the extraction of brines from the Salar de Atacama. Consequently, the foregoing will result in significant increases in payments to the State of Chile, for leases and taxes. At the same time, this investment will involve an increase in the number of highly qualified personnel, both for the construction and subsequent operation of the new processing plants.

SQM has been developing this industry since 1994, with significant investments in infrastructure, production plants and technology. The efforts in research and development, supported by a qualified team of employees, have allowed us to occupy a leading position worldwide, producing chemical products with high added value, and to look with optimism towards the development in the coming years.
