 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# MERCANTILE BANK CORP (NASDAQ: MBWM) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is MERCANTILE BANK CORP, listed on NASDAQ under ticker MBWM, with ISIN US5873761044 and LEI P16VZZCKTJ5IONL6XE37. Its security type is Corporate, its segment is not on the record, its sector is 6022 State Commercial Banks, and its jurisdiction is United States, Michigan. The issuer is listed and not halted.\n\n## The disclosure read\n\nThe record holds 47 filings in the twelve months to 2026-11-08, across 27 filing days. The median gap between filing days is 9.0 days. The latest filing is dated 2026-10-30, is a results filing, and is 9 days before the record date. The NASDAQ median cadence gap is 6.0 days across 4,359 issuers, and the NASDAQ median filings count is 52. The NASDAQ median latency is 5.0 days. The 6022 State Commercial Banks median cadence gap is 5.0 days across 214 issuers, the sector median filings count is 87.5, and the sector median latency is 3.0 days.\n\n## Auditor\n\nThe auditor of record is PLANTE & MORAN, PLLC, located in GRAND RAPIDS, MICHIGAN. 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. 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 own 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 vintage is sealed for the issuer 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/CIK0001042729.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/MBWM (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/1042729/000143774926005997/mbwm20251231_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/MBWM (the record)\n",
