(NYSE: CNR) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nCore Natural Resources, Inc. is listed on the NYSE under ticker CNR, with ISIN US2189371006. The LEI is not on the record (no GLEIF record with the exact legal name in jurisdiction US-DC). The security type is Corporate, the segment is not on the record, and the sector is 1220 Silver Ores. The jurisdiction is United States, District of Columbia. The issuer is listed and not halted.\n\n## The disclosure read\n\nThe record holds 71 filings on 33 filing days in the window 2025-11-08 to 2026-11-08. By type, the record holds 38 directors' dealings, 15 regulatory filings, 9 results, 3 ad hoc, 3 AGM/EGM, 2 corporate news and 1 director change. The median gap between filing days is 4.0 days. The latest filing is a results filing dated 2026-11-05, 3 days before the record date of 2026-11-08.

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.

Riley, Jefferies, Texas Capital and UBS.\n\n## Open research\n\nNo openly published research notes were found on the record.\n\n## Licensed\n\nLicensed research: none loaded.
