Been following this one since IPO.
Got out a few year back, before the Germans got excited, but managed to bag a 3-bagger from IPO.
Been following since. Got out because timelines being pushed back got me nervous. DYE's technologies were becoming redundant before they were likely to reach mass-production.
Read this on a flight last night and thought it was worth sharing

Having a technology is one thing, but you need to get it to market quickly and convincingly, in order to carve out market-share. Until DYE perfects its technologies, I fear the market may have already moved on.
Hope this helps holders.
