 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# Arqit Quantum Inc. (NASDAQ: ARQQ) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is Arqit Quantum Inc., listed on NASDAQ under the ticker ARQQ, with ISIN USG0567U1274. The LEI is not on the record, as no GLEIF record carries the exact legal name in jurisdiction US-E9. The security type is Non-operating entity type (other), the segment is not on the record, the sector is 7372 Services-Prepackaged Software, and the jurisdiction is the Cayman Islands. The issuer is listed and not halted.\n\n## The disclosure read\n\nThe record holds 183 filings in the twelve months from 2025-11-08 to 2026-11-08, across 70 filing days, with a median gap of 3 days between filing days. The filings comprise 114 directors' dealings, 1 halt or suspension, 6 prospectuses, 51 regulatory filings and 11 results. The latest filing is dated 2026-11-06, is of type directors' dealings, and is 2 days before the record date. The NASDAQ exchange median is a cadence gap of 6.0 days, 52 filings and a latency of 5.0 days. The sector median for 7372 Services-Prepackaged Software is a cadence gap of 5.0 days, 62.5 filings and a latency of 4.5 days.\n\n## Auditor\n\nThe auditor is not on the record, as the latest annual report cover carries no dei:AuditorName tag. The auditor's location is not on the record. The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds one delisting, dated 2026-09-02. It holds no listing and no name change. The domicile change is not on the record, as 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 reads listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable, as the chapter's orderability section carries no client categories and 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\nOne research house is named on the issuer's own investor-relations page: H.C. Wainwright.\n\n## Open research\n\nOne openly published research note is on the record, published by Equity Development Limited on 2021-07-19.\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 issuer is held in sealed years 2021, 2022, 2023, 2024, 2025 and 2026. The market's earliest sealed date is 2021-01-04. 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/CIK0001859690.json (identity.jurisdiction)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/ARQQ (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://ir.arqit.uk/stock-data/analyst-coverage (coverage)\n- https://www.equitydevelopment.co.uk/research/unbreakable-quantum-encryption-the-holy-grail-1 (open research)\n- https://mcp.us-cm-kg.ai/record/NASDAQ/ARQQ (the record)\n",
