## Documented share calculations

No documented private share-price and conversion model is enabled. Users may enter their own comparable prices; do not infer a per-share entry price from aggregate funding or company valuations.

## Later share adjustments

No separate share-class distribution is modeled.

## Coverage gaps and limitations

- The issuer history does not disclose pre-IPO preferred rounds, investor allocations or a complete historical conversion chain.

- The $10 public offering price is a historical fact, not a verified pre-IPO entry price.

- Subsequent splits and distributions are not reviewed for an automatic IPO-to-current calculation.

Entered prices and later-date share-basis assumptions are unverified. Excludes fees, taxes, dividends, warrants and other distributions; fractional shares are illustrative. Historical investor allocations, minimums and selling rights are not established.
