State company (1968–1983)
The company was created in 1968 as a Sociedad Minera Mixta between private investors and the State of Chile (Compañía Salitrera Anglo-Lautaro 62.5% and CORFO 37.5%). The new company was made up of the combination of the deposits and assets of the Compañía Salitrera Anglo-Lautaro and the Empresa Salitrera Victoria owned by CORFO.
At the end of 1966, the problem of the expiration of the state enterprise managed by COVENSA July 30, 1968, and how to organize the nitrate industry arose. Negotiations with Anglo-Lautaro to establish a partnership led to the creation of SQM, with the intent to restructure the declining nitrate production, increase investment and improve exploitation. As a result, SQM was given a monopoly in the exploitation and commercialization of nitrate.[4]
In 1971, the State of Chile, through CORFO, acquired 100% of the property and with this, the exploitation of nitrate was nationalized.
Private company (1983–)
Between 1983 and 1988, it was privatized again[4] during the military dictatorship, transferring the Chilean state company to Julio Ponce Lerou, the then son-in-law of Augusto Pinochet, for 20,300 million pesos through the transfer of 93% of the State shares despite the fact that the value was approximately 35,800 million pesos.[5]
In 1993, the operations of the technical grade potassium nitrate plant began.
In 1995, SQM was listed on the New York Stock Exchange and started the production of potassium chloride from the Salar de Atacama. Production of lithium carbonate from the Salar del Carmen started in 1997. In the years that followed, the business was internationalized through acquisitions and joint ventures:[4][6]
In 2015, the largest shareholder with 32% was the Julio Ponce Lerou's Pampa Group.[10]
In 2015, after flood damage to the railway, nitrate transport to the port by rail was replaced by trucking.
In 2018, China's Tianqi Lithium Corp. purchased 23.77% stake in SQM from Canadian mining company Nutrien Ltd.[11] In 2019, Tianqi Lithium came to an agreement over the governance of SQM with key shareholder Julio Ponce Lerou.[12]
In October 2023, SQM acquired a 30% stake in Australia's Pirra Lithium.[13]
