Investors in certrtain rounds (or sizes) tend to have no lockup, whereas later stages have a six month. Alternatively, I've reviewed agreements where the lockup is based on minimum market cap, but I've only seen that a couple of times.
> Holding Period. Before you may sell any restricted securities in the marketplace, you must hold them for a certain period of time. If the company that issued the securities is a “reporting company” in that it is subject to the reporting requirements of the Securities Exchange Act of 1934, then you must hold the securities for at least six months
You might be referring to staff members who have shares ? Their shares are not restricted securities as far as I know, but their internal company policy might affect those, but I'm not 100% certain on that.
It's hard to say that they footed the bill here, but they basically gave SpaceX a number to say "well our stock went IPO and it's at this price, so here's 60B at this price"
A good tactic from SpaceX as after the inital surge of a big IPO, the stock price usually comes down and finds it's correct balance, which is usually always lower. So if they had of waited the 'cooling off' period of a year for example, and the stock price went down to it's 'correct' valuation, then they would have had to issue a higher number of stocks.. At least that's my thinking, but I'm terrible with money.
