Cap vs Discount Math
NVCA Standard
The investor receives the lower of the Valuation Cap share price ($0.6250) or the Discount share price ($1.5000), resulting in an effective 66.7% discount from the Series A priced price ($1.8750). The new option pool is created post-conversion, proportionately diluting existing holders.
