Its security type is Corporate, its segment is not on the record, its sector is 8071 Services-Medical Laboratories, and its jurisdiction is United States, Delaware. Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 127 filings in the twelve months to 2026-11-08, across 55 filing days. The median gap between filing days is 3.0 days. The latest filing is dated 2026-11-05, 3 days before the record date, and is of type directors_dealings. The NYSE exchange median is 6.0 days cadence gap, 64.0 filings and 4.0 days latency across 3256 issuers. The sector median is 5.5 days cadence gap, 79 filings and 3 days latency across 29 issuers.\n\n## Auditor\n\nThe auditor of record is PricewaterhouseCoopers LLP, located in Florham Park, New Jersey. The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds no listing, delisting or name change lines. Domicile change is not on the record, as EDGAR states no dated change of state of incorporation on a filing line. 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, as 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\nThe field has no research houses on record; none was found on the pages read.\n\n## Open research\n\nThe record holds no openly published research notes; none was found.\n\n## Licensed\n\nLicensed research: none loaded.

The market's earliest sealed date is 2021-01-04, and 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://www.sec.gov/data-research/sec-markets-data/fails-deliver-data (identity.isin)\n- https://data.sec.gov/submissions/CIK0001022079.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/DGX (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/1022079/000102207926000015/dgx-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/DGX (the record)\n",
