No separate share-class distribution is modeled.

## Coverage gaps and limitations

- Pre-IPO member-bank interests are not interchangeable with listed Class A common stock. No private cash subscription price is inferred.

- IPO proceeds included restructuring and redemption uses. They do not all represent new operating capital.

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.
