 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# 908 Devices Inc. (NASDAQ: MASS) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is 908 Devices Inc., listed on NASDAQ under ticker MASS, with ISIN US65443P1021. The LEI is not on the record, as no GLEIF record with the exact legal name in jurisdiction US-DE exists. The security type is Corporate, the sector is 3826 Laboratory Analytical Instruments, and the jurisdiction is United States, Delaware. The segment is not on the record. The listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 99 filings in the twelve months to 2026-11-08, across 61 filing days. The median gap between filing days is 3.0 days. The latest filing is dated 2026-11-06, two days before the record date, and is of type directors_dealings. The NASDAQ peer median is 6.0 days cadence, 52 filings and 5.0 days latency across 4359 issuers. The sector peer median is 5.0 days cadence, 71.0 filings and 4.0 days latency across 24 issuers.\n\n## Auditor\n\nThe auditor of record is PricewaterhouseCoopers, LLP, located in Boston, Massachusetts. 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, 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, 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\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. The count is 0.\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's years sealed on the record are 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\n8 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/CIK0001555279.json (identity.jurisdiction)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/MASS (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/1555279/000110465926024877/mass-20251231x10k.htm (the auditor)\n- https://mcp.us-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://mcp.us-cm-kg.ai/record/NASDAQ/MASS (the record)\n",
