NovaBridge Biosciences (Nasdaq: NBP), an SEC filer in Pharmaceutical Preparations, closed at $1.89, +1.1%, on 2026-08-27, with a return on equity of -21.4%. Institutional ownership, earnings history and filed financials are on the tabs below.
% of shares outstanding not shown: this line files 20-F annual reports only — a foreign private issuer whose US listing trades as ADSs (depositary receipts), while its cover-page share count is in ORDINARY shares. The depositary ratio is not in our data. The count we hold for this line is 265,377,891 shares (as of 2025-12-31, source dei). Dividing one by the other is wrong by the whole ratio (a 5:1 ADR reads one fifth of the true percentage), so the percentage is withheld rather than served wrong. Holder share counts are shown as filed.
Crowding percentile lands with its cohort — the cohort is size-matched, so it needs a market cap for NBP in the served universe — that lands with the next screener build.
