The security type is Corporate. The segment is not on the record. The sector is 3674 Semiconductors & Related Devices and the jurisdiction is United States, Delaware. The listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 55 filings in the twelve months to 2026-11-08, on 37 filing days. The median gap between filing days is 6.0 days; the exchange median is 6.0 days and the sector median is 4.0 days. The latest filing is dated 2026-11-05 and is of type results, 3 days before the record date. Filing latency is 3 days; the exchange median is 4.0 days and the sector median is 4.0 days. Filings by type are: 20 directors' dealings, 14 regulatory filings, 9 results, 5 prospectuses, 4 director changes, 2 corporate news, and 1 AGM/EGM.\n\n## Auditor\n\nThe auditor of record is Ernst & Young Han Young, located in Seoul, Republic of Korea. The record shows no auditor changes.\n\n## Events and halts\n\nThe record shows no listing, delisting or name change lines. 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, as the exchanges' tier transfers are not EDGAR filings. 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/us/reasonable-basis-suitability-finra-rule-2111/r1, with the chapter as of 2026-11-04.\n\n## Coverage\n\nNo research houses were found on the issuer's investor-relations pages read; 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.

The live record began on 2026-09-12.\n\n## Sources\n\n9 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://mapping.gleif.org/api/v2/isin-lei/latest (identity.isin)\n- https://data.sec.gov/submissions/CIK0001325702.json (identity.jurisdiction)\n- https://mapping.gleif.org/api/v2/isin-lei/latest/download (identity.lei)\n- https://mcp.us-cm-kg.ai/events/NYSE/MX (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/1325702/000119312526108435/mx-20251231.htm (the auditor)\n- https://mcp.us-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.us-cm-kg.ai/record/NYSE/MX (the record)\n",
