(NASDAQ: AURA) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nAura Biosciences, Inc. is listed on NASDAQ under ticker AURA, with ISIN US05153U1079; its LEI is not on the record. Its security type is Corporate, its sector is 2836 Biological Products, (No Diagnostic Substances), its jurisdiction is United States, Delaware, and its segment is not on the record. Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 84 filings across 33 filing days in the window 2025-11-08 to 2026-11-08. The median gap between filing days is 5.0 days, against 6.0 days for the NASDAQ exchange median (4,359 issuers) and 5.5 days for the sector median (176 issuers). The latest filing is a regulatory filing dated 2026-10-27, 12 days before the record date of 2026-11-08, against a latency median of 5.0 days for the exchange and 4.0 days for the sector.\n\n## Auditor\n\nThe auditor is not on the record, because the latest annual report cover carries no dei:AuditorName tag. No auditor changes are on the record.\n\n## Events and halts\n\nThe record holds no listing, delisting or name change lines. The domicile change is not on the record, and the segment move is not on the record because the exchanges' tier transfers are not EDGAR filings. The halt flag is listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable under rule version acm-68000/us/reasonable-basis-suitability-finra-rule-2111/r1, as of 2026-11-04, because the chapter's orderability section carries no client categories and so the outcome cannot name its client category.\n\n## Coverage\n\nNo research houses were found on the issuer's investor-relations page.\n\n## Open research\n\nNo openly published research notes were found on the record.\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, 2022, 2023, 2024, 2025 and 2026. The market's earliest sealed date is 2021-01-04, and the live record began on 2026-09-12.\n\n## Sources\n\n7 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/CIK0001501796.json (identity.jurisdiction)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/AURA (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://mcp.us-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.us-cm-kg.ai/record/NASDAQ/AURA (the record)\n",
