Its security type is Corporate, its sector is NAF 70.10Z, and its jurisdiction is France (RCS-registered SA à conseil d'administration (s.a.i.)). Its segment is not on the record. Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 22 filings in the twelve months from 2025-11-06 to 2026-11-06, across 11 filing days. The filings comprise 15 directors' dealings, 2 newswire releases, 1 prospectus and 4 regulatory filings. The median gap between filing days is 18.0 days, against a Euronext Paris median of 8.0 days and an NAF 70.10Z median of 9 days. The latest filing is dated 2026-11-04, a regulatory filing, 2 days before the record date of 2026-11-06, against a Euronext Paris median latency of 3 days and an NAF 70.10Z median latency of 3 days. The median filings per issuer are 15.0 on Euronext Paris and 16.0 on NAF 70.10Z.\n\n## Auditor\n\nThe auditor of record is not on the record. The market's record carries the annual report link only and does not carry the auditor's name or location. Auditor changes are not on the record.\n\n## Events and halts\n\nThe record holds no listing, delisting, name change, domicile change or segment move dated on the record, because no lifecycle type map exists for this register yet. The halt flag is 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/fr/mifid-ii-product-governance/r1, and the chapter is as of 2026-11-04.\n\n## Coverage\n\nThe issuer's investor-relations page names 7 research houses: Berenberg, Exane BNP Paribas, ID Midcaps, Kepler Cheuvreux, Marex, Oddo and Portzamparc.\n\n## Open research\n\nNo openly published research notes are on the record. None was found.\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 market's vintage is not sealed. No issuer years are sealed, the market's earliest sealed date is not on the record, and the live record began date is not on the record.\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://registers.esma.europa.eu/publication/searchRegister?core=esma_registers_firds (identity.exchange)\n- https://recherche-entreprises.api.gouv.fr/search?q=572060333 (identity.jurisdiction)\n- https://mapping.gleif.org/api/v2/isin-lei/latest/download (identity.lei)\n- https://mcp.fr-cm-kg.ai/events/XPAR/FR0000039620 (the disclosure lines)\n- https://live.euronext.com/en/ajax/haltedInstrument/getAjax/current (the halt flag)\n- https://mcp.fr-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://www.mersen.com/en/investors/analyst-coverage (coverage)\n- https://mcp.fr-cm-kg.ai/record/XPAR/FR0000039620 (the record)\n",
