Santiago, Chile, April 23, 2018 – Sociedad Química y Minera de Chile S.A. (SQM) (NYSE: SQM; Santiago Stock Exchange: SQM-A, SQM-B), announced today that in accordance with Articles 9 and 10 of the Chilean Securities Market Law, and General Rule N° 30 of the Commission for the Financial Market (CMF), it informs the following as an essential fact ( hecho esencial) :

On April 2, 2018, Sociedad de Inversiones Pampa Calichera S.A. and Potasios de Chile S.A. (the "Shareholders") sent a letter to request that the Board of Directors of the Company (the "Board") summon an extraordinary shareholders’ meeting to review and resolve various matters. The Board called for an extraordinary shareholders' meeting to be held on April 27, 2018 and informed CMF and the market about it on April 3, 2018.

On April 20, 2018, the Shareholders sent a new letter to the Company stating that their boards of directors had agreed to withdraw their request to summon the extraordinary shareholders’ meeting referred to above. Likewise, in the same letter, the Shareholders informed that in their capacity as shareholders representing more than 10% of SQM´s issued shares with voting rights, they request that the Board of Directors, in accordance with article 58 No. 3 of the Public Companies Law, summon a new extraordinary shareholders’ meeting to review and resolve on the matters referred to in said letter.

The Board at an extraordinary session held today, reviewed the request filed by the Shareholders and agreed, unanimously, to cancel the Extraordinary Shareholders’ Meeting called for April 27, 2018 and confirm that this meeting would not take place. At the same time, the Board agreed, in accordance with the provisions of Article 58 No. 3 of the Public Companies Law, to summon an extraordinary shareholders’ meeting to review and resolve the following amendments to the Company’s By-laws (the “By-laws”):

To modify the articles 27, 28, 29, and 36, replacing the reference to the “Superintendence of Securities and Insurance” ( Superintendencia de Valores y Seguros ) with that of the “Commission for the Financial Market” ( Comisión para el Mercado Financiero ).

To modify the article 36 bis, adding the following last paragraph:

“The obligations indicated above in this article shall be understood as fulfilled at the moment said information is available on the Company’s website.”

To modify the article 41, replacing the reference to the “Superintendent of Securities and Insurance” ( Superintendente de Valores y Seguros ) with that of the “President of the Commission for the Financial Market.”

To modify the title of the “Transitory Article”, changing it to the “First Transitory Article.”

To introduce a new “Second Transitory Article” which reads as follows:

“FOR THE ENTIRE PERIOD BETWEEN THE DATE OF THE EXTRAORDINARY SHAREHOLDERS’ MEETING WHICH APPROVED THE INCORPORATION OF THIS TRANSITORY ARTICLE AND DECEMBER 31, 2030, THE RESTRICTION TO NOT VOTE MORE THAN 37.5% OF ANY SERIES OF COMPANY SHARES, AS ESTABLISHED BY THE THIRTY-FIRST ARTICLE OF THE BYLAWS, RECOGNIZES THE FOLLOWING EXCEPTION, WHICH WILL ONLY BE APPLICABLE TO THE ELECTION OF THE SERIES A BOARD MEMBERS OF THE COMPANY: If two or more people, related to each other or not, with or without an joint action agreement, acquire between now and December 31, 2030 (the “entering shareholders”), a quantity of the company’s A-series shares which allows them to exercise effective voting rights for more than 37.5% of the series, then any shareholder or group of shareholders listed in the respective registry as of this date, that owns a number of the company’s A-series shares corresponding to more than 37.5% of said series, shall have the right to vote a number of the company’s A-series shares in its power equivalent to the lesser of (i) the number of those series’ shares owned by the existing shareholders at the present date, and (ii) the number of those series’ shares for which the entering shareholders could exercise voting rights. Likewise, if, for any reason, one of the company’s shareholders listed in the respective registry to date and owner of a number of the company’s A-series shares corresponding to more than 37.5% of said series, were to acquire, between the present date and December 31, 2030, the capacity to exercise effective voting rights for more than 37.5% of the company’s A-series shares, whether as a result of a joint action agreement with other shareholders, including existing shareholders, or by any other means, then any other company shareholder or group of shareholders not related to them that owns a number of the company’s A-series shares corresponding to more than 37.5% of said series, including both existing and entering shareholders, shall have the right to vote a number of shares of said series in its power equivalent to the lesser of (i) the number of those series’ shares owned by the latter shareholder or shareholders, and (ii) the number of those series’ shares for which the existing shareholder has the capacity to exercise voting rights in excess of the 37.5% restriction.”

To adopt all other agreements necessary to carry out the abovementioned matters.

An Extraordinary Shareholders’ Meeting to review and resolve the abovementioned matters will be held on May 17, 2018 at 10:00am at Hotel NH Collection Plaza Santiago, located on Avenida Vitacura N°2610, Las Condes, Santiago.

Pursuant to subsection 2 of article 59 of the Public Companies Law, the Company informs that the documents sent by the Shareholders, which are the basis for the various options submitted to their vote, are available to shareholders at the SQM’s offices located on El Trovador 4285, 6th floor, Las Condes and on the Company's website (www.sqm.com, the "Website").

Finally, in accordance with the requirements of the CMF in the ordinary office No. 10,078, in which the Board was required to comment on whether the previous amendment proposal of the By-laws requested by the Shareholders, contributed or not to the corporate interest, the Board of Directors believes it is prudent to comment on the new proposal of the Shareholders and will do it with due anticipation before May 17, 2018.
