Selected historical funding and listing evidence, not a complete private cap table or live quote. Funding totals, company valuations and per-share prices are different measures. A hypothetical value is not actual sale proceeds; investor access is not established.

## 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

- Early private-round dates, preferred-share terms and a verified conversion chain are not available in the reviewed issuer sources.

- A reported early investor’s check or ownership stake is not sufficient to reconstruct a per-share return.

- The 1984 listing is documented; no unverified IPO price is inserted into the calculator.

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.
