Here is a really good analysis. 
“The Q2 report was disappointing compared to our expectations and the market reaction was also strongly negative. The company’s revenue of EUR 1.1 million was modest, especially when considering the large contract that still supported the figures in this quarter. We are lowering our estimates for the short and long term in view of the difficulties in the business and the continuing very low visibility. Despite the fall in the share price, the valuation seems even more challenging than before, as in addition to our estimates, our view on the acceptable multiples for the stock has gone down.”
