GHH is a European leading that produces wheels, axles, and wheel sets for world-wide use (32% of sales for export i.e. outside Germany, France, and Belgum) in rail vehicles, at its plants in Germany, France, and Belgium. Products are used both in locomotives, multiple units and locomotive-hauled rolling stock, for both freight and passenger trains, in tram and underground rail systems.

Upon disposal of the main subsidiary of GHH to its main competitor, the Altercap funds were fully repaid at par of their investment into the senior debt issued by GHH.
