(NASDAQ: IPDN) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nProfessional Diversity Network, Inc. is listed on NASDAQ under the ticker IPDN. The LEI is 549300NUI0D0LPHBZ355; the ISIN is not on the record, though the LEI carries the US ISINs US74312Y4008 and US74312Y5096. The security type is Corporate, the sector is 7370 Services-Computer Programming, Data Processing, Etc., and the jurisdiction is United States, Delaware. The segment is not on the record. The issuer is listed and not halted.\n\n## The disclosure read\n\nThe record holds 42 filings in the twelve months to 2026-11-08, on 34 filing days. The median gap between filing days is 6 days. The latest filing is dated 2026-10-28, 11 days before the record date; it is a regulatory filing. The NASDAQ median cadence gap is 6.0 days, and the NASDAQ median latency is 5.0 days. The sector median cadence gap is 5 days, and the sector median latency is 5 days. The issuer's 42 filings are below the NASDAQ median of 52 filings and below the sector median of 63 filings.\n\n## Auditor\n\nThe auditor of record is SR CPA & Co., located in Hong Kong. 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, since EDGAR states no dated change of state of incorporation on a filing line. The segment move is not on the record, since the exchanges' tier transfers are not EDGAR filings. The issuer is listed and 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 page.\n\n## Open research\n\nNo openly published research notes were found on the record.\n\n## Licensed\n\nLicensed research: none loaded.

The sealed years that hold the issuer are 2021, 2022, 2023, 2024, 2025 and 2026. The earliest sealed date of the market 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://data.sec.gov/submissions/CIK0001546296.json (identity.jurisdiction)\n- https://api.gleif.org/api/v1/lei-records/549300NUI0D0LPHBZ355 (identity.lei)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/IPDN (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/1546296/000143774926010515/ipdn20251231_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/IPDN (the record)\n",
