 "markdown": "The page is the record's research on the issuer — no analyst, no rating, no view.\n\n# Ero Copper Corp. (NYSE: ERO) — research page\n\nAs of 2026-11-08 · us-cm-kg · record version 1\n\n## Identity and listing\n\nThe issuer is Ero Copper Corp. It is listed on NYSE under ticker ERO, ISIN US2960061099. The record holds no LEI, as no GLEIF record with the exact legal name in jurisdiction US-A1 exists. The security type is non-operating entity type (other). The segment is not on the record. The sector is 1000 Metal Mining. The jurisdiction is British Columbia, Canada. The listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 29 filings in the twelve months to 2026-11-08, across 26 filing days. Of these, 22 are results and 7 are regulatory filings. The median gap between filing days is 10 days. The latest filing is dated 2026-11-02 and is a results filing, 6 days before the record date. The exchange median cadence gap is 6.0 days, the exchange median filings are 64.0, and the exchange median latency is 4.0 days. The sector median cadence gap is 6.5 days, the sector median filings are 46.0, and the sector median latency is 6.0 days.\n\n## Auditor\n\nThe auditor is not on the record, as the latest annual report cover carries no dei:AuditorName tag. 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, 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 issuer is 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. The count is 0.\n\n## Open research\n\nNo openly published research notes were found on the record. The count is 0.\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 sealed years are 2021, 2022, 2023, 2024, 2025 and 2026. The market's earliest sealed date is 2021-01-04.
