Complete Filing Data
Boundless Bio, Inc. reported Stockholders Equity Including Portion Attributable To Noncontrolling Interest of $98.65 million for FY2025.
All values from 10-K, 20-F, and 10-Q filings on SEC EDGAR, organized by financial statement. Scroll each table horizontally for the full history. Blank cells mean Boundless Bio, Inc. did not report that metric for that period in XBRL — often because accounting standards changed which tag a company files under (for example, most companies moved revenue to the ASC-606 tag in 2018), so a metric may continue in a different row. Rows marked * merge those successor tags into one continuous series, preferring the audited value from the newest-standard tag where periods overlap.
