 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# ProQR Therapeutics N.V. (NASDAQ: PRQR) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nProQR Therapeutics N.V. is listed on NASDAQ under ticker PRQR, with ISIN USN715421095. The LEI is not on the record, because no GLEIF record carries the exact legal name in jurisdiction US-P7. The security type is Non-operating entity type (other), the sector is 2834 Pharmaceutical Preparations, and the jurisdiction is Netherlands. The segment is not on the record. The issuer is listed and not halted.\n\n## The disclosure read\n\nThe record holds 50 filings in the window 2025-11-08 to 2026-11-08, across 29 filing days. The filings are 18 directors' dealings, 3 prospectus, 9 regulatory filings and 20 results. The median gap between filing days is 6.0 days. The latest filing is a results filing dated 2026-10-30, which is 9 days before the record date of 2026-11-08. On NASDAQ the median cadence gap is 6.0 days across 4359 issuers, the median filings count is 52 and the median latency is 5.0 days. In sector 2834 Pharmaceutical Preparations the median cadence gap is 6.0 days across 526 issuers, the median filings count is 63.0 and the median latency is 4.0 days. The issuer's filings count of 50 is below both medians. Its latency of 9 days is above both medians.\n\n## Auditor\n\nThe auditor is not on the record, because 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, because EDGAR states no dated change of state of incorporation on a filing line. The segment move is not on the record, because the exchanges' tier transfers are not EDGAR filings. The halt flag reads listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable under the rule version acm-68000/us/reasonable-basis-suitability-finra-rule-2111/r1. The chapter's orderability section carries no client categories, so the outcome cannot name its client category. The chapter was as of 2026-11-04.\n\n## Coverage\n\nNo research houses were found on the issuer's investor-relations page.\n\n## Open research\n\nNo openly published research notes were found on the record.\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 sealed years that hold the issuer are 2021, 2022, 2023, 2024, 2025 and 2026. The earliest sealed date of the market is 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/CIK0001612940.json (identity.jurisdiction)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/PRQR (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/PRQR (the record)\n",
