Today, Glencore is one of the largest global diversified natural resource commodity companies in the world, producing and trading more than 90 commodities.
How we started
We were founded in 1974 as Marc Rich + Co AG; we initially focused on the physical marketing of ferrous and non-ferrous metals and minerals and crude oil. Shortly afterwards, we expanded into oil products.
In 1981, we acquired an established Dutch grain trading company, which was the basis for our agricultural products business; later that year we added coal to our energy products segment.
Diversifying through the value chain
From 1987, we began to diversify from purely marketing and trading, through key acquisitions in mining, smelting, refining and processing. We made our first equity investment in an industrial asset when we acquired 27% of the Mt. Holly aluminium smelter in the US. This was followed by our first controlling interest in an industrial asset in 1988: a 66.7% interest in a zinc/lead mine in Peru.
We acquired a stake in Xstrata (then Sudelektra AG) in 1990. We were renamed Glencore International in 1994 following a management buyout.
Becoming a listed company
We listed on the London and Hong Kong Stock Exchanges in 2011 and on the Johannesburg Stock Exchange in 2013.
