Grupo Pampa carried out a corporate simplification process that reorganized its structure, reducing the number of companies from six to two investment vehicles: Pampa Investments and Potasios Investments.

In the first stage, the process involved the absorption of Pampa Calichera by Oro Blanco and the reverse merger of Nitratos into Potasios.

Subsequently, Potasios sold its stake in Pampa Calichera to Norte Grande, as part of the reorganization needed to move toward the new structure.

Subsequently, Oro Blanco absorbed its subsidiary Global Mining and incorporated Norte Grande through a reverse merger. As a result, Oro Blanco remained as the surviving company and was subsequently renamed Pampa Investments.

At Potasios’ Extraordinary Shareholders’ Meeting, the consolidation of the Class A and Class B shares was approved, terminating their respective preferences and limitations. As a result, the capital remains divided into the same number of shares, all of which are common, registered, without par value, and of a single class.

As a result, Grupo Pampa now consists of Pampa Investments, which consolidates the group’s entire stake in SQM S.A., and Potasios Investments. Both companies operate as long-term investment vehicles, more directly linked to the underlying asset.

This process enabled the Company to move toward a structure that is simpler, more efficient, and easier for the market to understand, with greater agility in decision-making and a clearer relationship between shareholders and the underlying asset, SQM S.A.
