Reading Astronomer's cap table

Share classes are listed senior-first: in a sale or liquidation, higher-seniority preferred stock is paid its liquidation preference before junior classes and common see proceeds. A participating class takes its preference and shares in the remainder; a non-participating class chooses one or the other.

The original issue price is what investors paid per share in that class’s round — read against current secondary prices, it shows which investors are above or below water.
