I think it's related to risk-aversion of investors in EU. While spitting out millions of dollars anything with a slight chance of success is common in the US (and to some degree in UK apparently), EU investors are much more conservative in their spending, which affects the valuation of these companies.

The road map seems promising also, I'll definitely keep an eye on it as well.
