 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# MESA LABORATORIES INC /CO/ (NASDAQ: MLAB) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is MESA LABORATORIES INC /CO/, listed on NASDAQ under ticker MLAB, ISIN US59064R1095, LEI 549300ZCG738WLX8ZW79. Its security type is Corporate, its segment is not on the record, its sector is 3823 Industrial Instruments For Measurement, Display, and Control, and its jurisdiction is United States, Colorado. The issuer is listed, not halted.\n\n## The disclosure read\n\nThe record holds 60 filings across 31 filing days in the window 2025-11-08 to 2026-11-08. The median gap between filing days is 7.5 days, against 6.0 days for NASDAQ and 5.5 days for the sector. The latest filing is dated 2026-10-29, is of type directors_dealings, and is 10 days before the record date of 2026-11-08. The median latency is 5.0 days for NASDAQ and 5.5 days for the sector. The median filings count is 52 for NASDAQ and 80.0 for the sector.\n\n## Auditor\n\nThe auditor of record is Baker Tilly LLP, located in Los Angeles, California. 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 is listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable, because 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\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 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\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://mapping.gleif.org/api/v2/isin-lei/latest (identity.isin)\n- https://data.sec.gov/submissions/CIK0000724004.json (identity.jurisdiction)\n- https://mapping.gleif.org/api/v2/isin-lei/latest/download (identity.lei)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/MLAB (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/724004/000072400426000047/mlab20260331_10k.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/MLAB (the record)\n",
