NOT SELLING TILL KSS is US$200m market cap, page-8

I agree. Only a small chance of launch failing. Most nano satellite missions that go wrong are not to do with launch failure. There is a high mission failure rate for small sats.
Kleos have 4 satellites that need to succeed for a successful mission. So the probability of success would be lower than for a single satellite.
We might not know the result for some months after launch.
If they are successful, it will take some time before any revenue comes in.
The loan is due in Feb I believe.
The company has not announced any contracts with detail on revenue that I am aware of.
The $50m revenue figure is entirely made up on this forum.
