 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# Septerna, Inc. (NASDAQ: SEPN) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is Septerna, Inc., listed on NASDAQ under ticker SEPN. Its ISIN is US81734D1046 and its LEI is not on the record (no GLEIF record with the exact legal name in jurisdiction US-DE). Its security type is Corporate, its segment is not on the record, its sector is 2834 Pharmaceutical Preparations, and its jurisdiction is United States, Delaware. Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 74 filings across 41 filing days in the window from 2025-11-08 to 2026-11-08. Filings by type are 36 directors' dealings, 20 regulatory filings, 8 results, 6 corporate news, 3 AGM/EGM and 1 prospectus. The median gap between filing days is 5.0 days. The latest filing is dated 2026-11-04, four days before the record date of 2026-11-08, and is of type corporate news. For NASDAQ the record holds 4,359 issuers, a median of 52 filings, a median cadence gap of 6.0 days and a median latency of 5.0 days. For the sector 2834 Pharmaceutical Preparations the record holds 526 issuers, a median of 63.0 filings, a median cadence gap of 6.0 days and a median latency of 4.0 days.\n\n## Auditor\n\nThe auditor of record is not on the record (no dei:AuditorName tag on the latest annual report cover; foreign private issuers and older filings carry none). Its location is not on the record. The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds no listing, delisting or name change lines for the issuer. The domicile change is not on the record (EDGAR states no dated change of state of incorporation on a filing line). The segment move is not on the record (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 is as of 2026-11-04.\n\n## Coverage\n\nNo research houses were found on the issuer's investor-relations page. The record names zero houses.\n\n## Open research\n\nNo openly published research notes were found. The record holds none.\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 issuer's years sealed are 2023, 2024, 2025 and 2026. The market's vintage is sealed, with earliest sealed date 2021-01-04. 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/CIK0001984086.json (identity.jurisdiction)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/SEPN (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/SEPN (the record)\n",
