I believe IPO price was way too low! Should have been at least $1.50 as indicated by listing price. This was due to the uncertainty of Covid19 and I think 4dx were pressured by greedy institutions that saw an opportunity for a bargain and quick instant profit.
Regarding future revenue, it's still hard to know how quickly it can be rolled out to hospitals/doctors, but they already have many of the Top 10 US hospitals on board from years ago during the development of the tech. Basically, there is still a lot of speculation about future earnings, but I understand this market, and I believe it's a no brainers that a multibillion dollar valuation will be justified by multimillion dollar revenue in due time... better to get in early (if you haven't already) pre-announcement, rather than risk buying at a premium waiting for revenue announcements imo.
