 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# Abivax S.A. (NASDAQ: ABVX) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is Abivax S.A., listed on NASDAQ under ticker ABVX, with ISIN US00370M1036. The LEI is not on the record, as no GLEIF record carries the exact legal name in jurisdiction US-I0. The security type is non-operating entity type (other), the segment is not on the record, the sector is 2834 Pharmaceutical Preparations, and the jurisdiction is France. The issuer is listed and not halted.\n\n## The disclosure read\n\nThe record holds 29 filings in the twelve months from 2025-11-08 to 2026-11-08, across 21 filing days. Of these, 3 are prospectuses, 14 are regulatory filings and 12 are results. The median gap between filing days is 10.5 days. The latest filing is dated 2026-09-21 and is of type results, 48 days before the record date of 2026-11-08. The NASDAQ exchange median is 52 filings, a median cadence gap of 6.0 days and a median latency of 5.0 days across 4359 issuers. The sector median for 2834 Pharmaceutical Preparations is 63.0 filings, a median cadence gap of 6.0 days and a median latency of 4.0 days across 526 issuers.\n\n## Auditor\n\nThe auditor is not on the record, as the latest annual report cover carries no dei:AuditorName tag, and foreign private issuers and older filings carry none. The auditor's 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. 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 issuer is listed and 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 own 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 issuer's years sealed are 2022, 2023, 2024, 2025 and 2026. The market's vintage is sealed, with an earliest sealed date of 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/CIK0001956827.json (identity.jurisdiction)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/ABVX (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/ABVX (the record)\n",
