Coby has made it clear that WBT focus is on the embedded market and discrete NVM will follow.
Here it is in an excellent article comparing FRAM, ReRAM, MRAM

and
" As CEO Coby Hanoch previously told EE Times, the plan was that embedded ReRAM revenue would fund advances on the discrete front, including the selector, while investing opportunities for neuromorphic computing applications was a longer-term opportunity."

So if you want to get a handle on what WBT is worth, look up "market cap based on revenue"
and project what revenue you are expecting for WBT over the next few years for the $1b to be market it has not entered yet.
Then work out the MC compared to what is now and you should be able to determine its value to you now.

The words "ReRam revenue would fund advances on the discrete front, including the selector" from Coby should help motivate you.

IMO. DYOR.
