My gut feeling is they are in it for the long haul. They are from Switzerland but moved to London recently. I'll try to dig up what I can on them though.
I think they saw something really good inside there and wanted to be a big part of it. NMUS is just so undervalued it just seems like a giant investment but if u compare that investment to some of the higher valued companies it doesn't seem so big.
