IPO Period

2/6/20

12/9/20

9/16/20

1. Help me to calculate the amount of money of the existing shareholders before and after an IPO.

2. Please find me which share of the company pre-IPO shareholders had at the end of the IPO day.

3. And find the company's total value at the end of the first day of trading (or a post-money valuation).

4. Did the shareholders of these three companies win or lose right after this lock-up period expired?

Thank you!
