ABOUT ROBIT
From Robit’s Website:
“Robit is a strongly internationalized growth company servicing global customers and selling drilling consumables for applications in underground and surface mining, construction, geotechnical and well drilling. The company’s offering is divided into three product and application groups: Top Hammer, Down the Hole and Geotechnical.
The foundation of the Robit story is strong and determined internationalization. The acquisitions, Drilling Tools Australia Pty Ltd and Bulroc (UK) Ltd, made in summer 2016 strengthened significantly Robit’s international operations. In addition, Robit purchased manufacturing assets and IPRs from Halco International LLC and Halco America LLC in January 2017 as well as further finalized the Halco acquisition in February 2017 by purchasing a majority of Halco Brighouse Ltd’s shares in England. As a result of the Halco acquisition Robit has further strengthened its Down-the-Hole business as a complement to the acquisitions made in Australia and England in May-July 2016. Robit emphasizes that it is a global company specializing in selling drilling consumables via its comprehensive distribution network in the global market.
Robit has its own sales and service points in seven countries as well as an active dealership network through which it sells to more than 100 countries. Robit’s manufacturing units are located in Finland, South Korea, Australia, and the UK. Robit’s shares are listed on NASDAQ Helsinki Ltd.”
