2026-10-02 is the ex-distribution boundary for the spin-off. Nasdaq and Yahoo use different adjustment methods for the preceding period. The complete adjustment factors have not been independently verified, so neither source can simply be described as unadjusted prices. Nasdaq prices are displayed as supplied, with returns and rebased indexes disabled; the candidate Yahoo series remains quarantined.

The closing-price conflict for 2025-06-30 was resolved using original quarter-end holdings filings with the SEC

The original Yahoo closing value for that day is retained (approximately USD 21.90). The Form 13F market-value/share-count ratios reported independently by Vanguard, Marex and Seven Grand for the same date and common-stock CUSIP support 21.90. SEC instructions require valuation at the close of the last trading day of the quarter, rounded to the nearest dollar. Nasdaq's 21.31 is retained as the rejected candidate. This resolution covers only that day's close; it does not describe OHLC, volume or other dates as SEC-verified.

The security’s first trading day has not been independently confirmed. The source’s earliest record is not automatically the start of listing.

The history starts with the provider’s first actual observation; this starting point is not a verified initial listing date; History cache update pending; the previous observation time is retained.

The current ticker and issuer have been checked across available sources; earlier issuer continuity and the first listing date are not independently confirmed.

Complete dates do not mean every historical price has been independently verified. Each segment uses its stated source definition. Returns are not calculated across corporate actions whose adjustments are unverified. Different issuers, currencies or adjustment versions are not stitched together automatically.

Current-source identity and the complete historical security lineage are verified separately

Available SEC filing indexes, historical entity names, listed tickers and source coverage have been reviewed individually. A shared CIK in the index does not establish continuity across successive share classes and reorganizations; the complete historical security lineage has not been marked as verified.

How to read this table

Extended history retrieved
An extended daily series available from the source has been retrieved. Whether it reaches listing requires separate checks of the verified listing date and security identity.
Valid closes and date records
Conflicting or invalid prices retain their dates with blank values. Valid-close counts exclude these blanks; charts do not fill gaps with zero.
Historical continuity
One ticker may span renaming, restructuring or issuer changes. ADRs, local shares, different currencies and SPAC predecessors are not merged automatically.
Price and operating history
Financial and operating metrics depend on their source documents and disclosure definitions. A longer price history does not justify inventing earlier operating data.
