Earlier quoted context omitted.
Almost certainly an amount that wipes out common stock holders. People they want to keep will get a retention offer, but with the acknowledgment that their stock in Chariot is now worth $0.
First of all, the story doesn't mention anything about the size of the deal. Second of all, the company is selling after ~2 years. The average employee has probably been there for less than 1 year. Excluding the common stock of the founders (since they are the ones who made the decision to sell), employee common stock grants and common stock options are all about ensuring employees get a share of blockbuster company…
The reason I mention it is because it's easy to get sucked into the trap of "hey they exited for $30m, and the person who gave up $40k/year salary for 2% ownership just got a check for $600k!" when that simply isn't realistic. Unless everything goes exactly right, common stock isn't really worth the risk. I think it's an important distinction to make.
Again, not saying anyone got "screwed", just that even in this case, an 8-figure exit could very well mean no common stock holders got a dime. I'm very curious about the terms of the Cruise deal as well -- a 10 figure exit (!), but I'm interested to find out how much the common stock there was actually worth.
