 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# Quantumsphere Acquisition Corp (NASDAQ: QUMS) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is Quantumsphere Acquisition Corp, listed on NASDAQ under ticker QUMS. ISIN USG7387B1064; LEI not on the record (no GLEIF record with the exact legal name in jurisdiction US-E9). Security type is SPAC (by SIC 6770); segment not on the record; sector 6770 Blank Checks; jurisdiction Cayman Islands. Listing status: listed, not halted.\n\n## The disclosure read\n\nThe record holds 16 filings in the twelve months to 2026-11-08, across 13 filing days, of which 1 is ad hoc, 3 corporate news, 7 regulatory filing and 5 results. The median gap between filing days is 19.0 days. The latest filing is dated 2026-10-13 and is a regulatory filing, 26 days before the record date. The NASDAQ peer median is 52 filings, a median cadence gap of 6.0 days and a median latency of 5.0 days across 4359 issuers. The 6770 Blank Checks peer median is 26 filings, a median cadence gap of 6.5 days and a median latency of 44 days across 819 issuers.\n\n## Auditor\n\nThe auditor is not on the record (no dei:AuditorName tag on the latest annual report cover; foreign private issuers and older filings carry none). Auditor 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. Domicile change is not on the record (EDGAR states no dated change of state of incorporation on a filing line). Segment move is not on the record (the exchanges' tier transfers are not EDGAR filings). Halt flag: 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. Signal code and rule version: acm-68000/us/reasonable-basis-suitability-finra-rule-2111/r1, chapter as of 2026-11-04.\n\n## Coverage\n\nNone found: the issuer's investor-relations page names no research houses, and the record holds a count of 0.\n\n## Open research\n\nNone found: the record holds no openly published research notes for the issuer.\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 record holds the issuer's sealed years 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\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/CIK0002070900.json (identity.jurisdiction)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/QUMS (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/QUMS (the record)\n",
