Products and brands

Norilsk Nickel had bought a 51% stake in Stillwater in 2003, but in November 2010 Norilsk Nickel announced plans to sell this stake. The South African mining company Sibanye Gold Limited proposed in December 2016 to acquire Stillwater for $2.2 billion ($18/share, a 61-percent premium over its average share price during the previous 52 weeks). The merger was approved by the Committee on Foreign Investments in April 2017 and was completed in May. The new owners pledged to honor Stillwater's Good Neighbor Agreement, which requires notification of surrounding communities about anything which might affect them.

In December 2010, the Company acquired Marathon PGM Corporation. It was renamed Stillwater Canada.
