(NASDAQ: RBBN) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is Ribbon Communications Inc., listed on NASDAQ under ticker RBBN, with ISIN US7625441040 and LEI 549300L1E8Z8RL7CUL52. Its security type is Corporate, its segment is not on the record, its sector is 7373 Services-Computer Integrated Systems Design, and its jurisdiction is United States — Delaware. Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 46 filings from 2025-11-08 to 2026-11-08, across 22 filing days. The median gap between filing days is 10 days. The latest filing is dated 2026-11-03, 5 days before the record date, and is of type directors_dealings. The NASDAQ exchange median is 52 filings, a median cadence gap of 6.0 days, and a median latency of 5.0 days across 4359 issuers. The sector median is 67.0 filings, a median cadence gap of 5.8 days, and a median latency of 5.0 days across 60 issuers.\n\n## Auditor\n\nThe auditor of record is Deloitte & Touche LLP, located in Dallas, Texas. 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, 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.\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 issuer's years sealed are 2021, 2022, 2023, 2024, 2025 and 2026. The market's earliest sealed date is 2021-01-04, and 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/CIK0001708055.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/RBBN (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/1708055/000170805526000012/rbbn-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/RBBN (the record)\n",
