Its security type is Corporate, its segment is ASQ1, its sector is Chemicals [552010], and its jurisdiction is Scotland per the Companies House jurisdiction field. Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 66 filings on 59 filing days in the window 2025-11-06 to 2026-11-06. The median gap between filing days is 6.0 days. The latest filing is dated 2026-11-04, is of type agm_record_date, and sits 2 days before the record date of 2026-11-06. The exchange median cadence gap is 7.0 days across 594 AIM issuers, and the exchange median latency is 4 days. The sector median cadence gap is 6.0 days across 17 issuers, and the sector median latency is 3 days.\n\n## Auditor\n\nThe auditor of record is PKF Littlejohn LLP. Its location is not on the record. Auditor changes are not on the record, as the market's record does not carry them.\n\n## Events and halts\n\nListing, delisting, name change, domicile change and segment move are not on the record, as 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 for elective professional client and for eligible counterparty, because the rule states a product scope and the subject's record carries no instrument class to place within it. The rule version is acm-68000/uk/product-governance-fca-prod-sourcebook/r1, with the chapter 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 on the record; 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 vintage is not sealed, and no issuer years are sealed. The market's earliest sealed date is not on the record. The live record began on 2026-09-11. Years 2021 through 2026 are sealed in the store but not served as of a date, and the as-of door answers not_sealed.\n\n## Sources\n\n10 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.londonstockexchange.com/live-markets/market-data-dashboard/price-explorer (identity.exchange)\n- https://api.londonstockexchange.com/api/gw/lse/instruments/alldata/MDH (identity.isin)\n- https://find-and-update.company-information.service.gov.uk/company/SC680788 (identity.jurisdiction)\n- https://mapping.gleif.org/api/v2/isin-lei/latest/download (identity.lei)\n- https://www.londonstockexchange.com/stock/MDH/mendell-helium-plc/company-page (identity.sector)\n- https://mcp.uk-cm-kg.ai/events/AIM/MDH (the disclosure lines)\n- https://marketsecurities.fca.org.uk/officiallist (the halt flag)\n- https://find-and-update.company-information.service.gov.uk/company/SC680788/filing-history/MzQ4Mzc5NjU3MGFkaXF6a2N4/document?format=pdf&download=0 (the auditor)\n- https://mcp.uk-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.uk-cm-kg.ai/record/AIM/MDH (the record)\n",
