Sirona said 90 million usd upfront for a reasonAnd now its been years investors have waited for them to deliver this deal. I think that if they dont come through with this number or close to it as their upfront payment then the TSXV will yawn at a deal. How pathetic is it when investors are now lowering their expectations that 20 mill will do or how about no upfront and all backend.If they after all this hype get some lower upfront or no upfront and all back end, then that tells me the partner they did a deal with is not serious. A large upfront payment says their partner is serious and is gonna work fast to get a return on their investment. On a side note how ShiiiTTY is stock house. how about put some money into this site?
