Thanks for this excellent analysis! I've been investigating CLIR over the last month, and I agree that there seem to be a lot of factors lining up in their favour, and the biggest risks seem to be dilution or cash burn. Because if they can survive long enough for their bigger projects to completed, and validated to other industry participants / buyers, I can't see how their solution doesn't start flying off the shelves. It has too many advantages to not.
The warranty liabilities over the last quarter were disappointing, but I expect revenues to be lumpy for the next couple of years. I've just opened a position and will be watching closely!
And yes to this:
"**It all boils down to their ability to scale in the next 2 years to avoid dilution."**

Hahah, yes, that is exactly what I thought, and what ChatGPT and Gemini encouraged me to believe as well. I'm glad I asked here before making further trades.
The ticker that I was looking at is CLIR, OCC memos 58534 and 58540.
Although I won't be trading adjusted options again any time soon, it has been a really fun journey delving into some of the mechanics of them.
Thanks again for your input and advice.
