 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# MBX Biosciences, Inc. (NASDAQ: MBX) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nMBX Biosciences, Inc. is listed on NASDAQ under ticker MBX, with ISIN US55287L1017. The LEI is not on the record (no GLEIF record with the exact legal name in jurisdiction US-DE). The security type is Corporate, the sector is 2834 Pharmaceutical Preparations, 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 87 filings across 46 filing days in the window 2025-11-08 to 2026-11-08. Of these, 38 are regulatory filings, 28 are directors' dealings, 7 are results, 6 are corporate news, 4 are director changes, 3 are AGM/EGM filings, and 1 is a prospectus. The median gap between filing days is 4 days. The latest filing is dated 2026-11-05, three days before the record date, and is of type directors_dealings. On NASDAQ the median filings count is 52, the median cadence gap is 6.0 days and the median latency is 5.0 days across 4359 issuers. On the sector 2834 Pharmaceutical Preparations the median filings count is 63.0, the median cadence gap is 6.0 days and the median latency is 4.0 days across 526 issuers. The issuer's filings count of 87 is above the NASDAQ median and above the sector median. Its cadence gap of 4 days is below both medians.

The 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. The domicile change is not on the record (EDGAR states no dated change of state of incorporation on a filing line). The segment move is not on the record (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 investor-relations pages read.

No licensed row is loaded.\n\n## As-of depth\n\nThe sealed years that hold the issuer are 2022, 2024, 2025 and 2026. The market's vintage is sealed, with the earliest sealed date 2021-01-04. The live record began 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/CIK0001776111.json (identity.jurisdiction)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/MBX (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/MBX (the record)\n",
