(NASDAQ: BOLD) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is Boundless Bio, Inc., listed on NASDAQ under ticker BOLD, ISIN US10170A1007. The LEI is not on the record, as no GLEIF record carries the exact legal name in jurisdiction US-DE. The security type is Corporate, the sector is 2834 Pharmaceutical Preparations, and the jurisdiction is United States, Delaware. The segment is not on the record. The listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 51 filings in the twelve months to 2026-11-08, across 30 filing days. The filings are 23 directors_dealings, 14 regulatory_filing, 5 results, 3 agm_egm, 3 prospectus, 2 corporate_news and 1 ad_hoc. The median gap between filing days is 6 days. The latest filing is directors_dealings, dated 2026-11-05, 3 days before the record date. The NASDAQ median cadence gap is 6.0 days, and the NASDAQ median latency is 5.0 days, across 4,359 issuers. The NASDAQ median filings count is 52. The 2834 Pharmaceutical Preparations sector median cadence gap is 6.0 days, and its median latency is 4.0 days, across 526 issuers. The sector median filings count is 63.0.\n\n## Auditor\n\nThe auditor of record is KPMG LLP, located in San Diego, CA. The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds no listing, delisting or name change lines. The domicile change is not on the record, as EDGAR states no dated change of state of incorporation on a filing line. The segment move is not on the record, as the exchanges' tier transfers are not EDGAR filings. The halt flag reads listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable. The chapter's orderability section carries no client_categories, so the outcome cannot name its client category. The rule version is acm-68000/us/reasonable-basis-suitability-finra-rule-2111/r1, and the chapter was as of 2026-11-04.\n\n## Coverage\n\nNo research houses were found on the issuer's investor-relations page. The count is 0.\n\n## Open research\n\nNo openly published research notes were found. The count is 0.\n\n## Licensed\n\nLicensed research: none loaded. A licensed row is served only to an agent whose firm holds that licence (licensor, entitlement). No licensed row is loaded.\n\n## As-of depth\n\nThe sealed years that hold the issuer are 2021, 2023, 2024, 2025 and 2026. The market's earliest sealed date is 2021-01-04. The live record began on 2026-09-12.\n\n## Sources\n\n8 source pages are named on this page; every value above carries its own source page and read date in the numbers.\n\n- https://www.sec.gov/files/company_tickers_exchange.json (identity.exchange)\n- https://www.sec.gov/data-research/sec-markets-data/fails-deliver-data (identity.isin)\n- https://data.sec.gov/submissions/CIK0001782303.json (identity.jurisdiction)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/BOLD (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/1782303/000119312526097543/bold-20251231.htm (the auditor)\n- https://mcp.us-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.us-cm-kg.ai/record/NASDAQ/BOLD (the record)\n",
