The LEI is not on the record, because no GLEIF record with the exact legal name in jurisdiction US-DE exists. The security type is Corporate. The segment is not on the record. The sector is 3350 Rolling Drawing & Extruding of Nonferrous Metals, and the jurisdiction is United States, Delaware. The issuer is listed and not halted.\n\n## The disclosure read\n\nThe record holds 79 filings in the window 2025-11-08 to 2026-11-08, across 46 filing days. The median gap between filing days is 4 days. The latest filing is dated 2026-11-03, 5 days before the record date of 2026-11-08, and is of type directors_dealings. The exchange median is 6.0 days cadence, 52 filings and 5.0 days latency, and the issuer's cadence of 4 days is below that median. The sector median is 4 days cadence, 79 filings and 5 days latency across 5 issuers. The window holds 35 directors_dealings, 26 regulatory_filing, 8 results, 5 corporate_news, 4 director_change and 1 agm_egm filing.\n\n## Auditor\n\nThe auditor of record is Deloitte & Touche LLP, located in Nashville, Tennessee. The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds no listing, delisting, name change or segment move events. The domicile change is not on the record, because EDGAR states no dated change of state of incorporation on a filing line. The segment move is not on the record, because 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\nThe issuer's own investor-relations page names 5 research houses: Barclays, JP Morgan, KeyBanc, UBS and Wells Fargo.\n\n## Open research\n\nThe record holds no openly published research notes for the issuer; none was found.\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 record holds the issuer's sealed years 2021, 2022, 2023, 2024, 2025 and 2026. The market's earliest sealed date is 2021-01-04. 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/CIK0000811596.json (identity.jurisdiction)\n- https://mcp.us-cm-kg.ai/events/NASDAQ/KALU (the disclosure lines)\n- https://www.nasdaqtrader.com/rss.aspx?feed=tradehalts (the halt flag)\n- https://www.sec.gov/Archives/edgar/data/811596/000119312526059575/kalu-20251231.htm (the auditor)\n- https://mcp.us-cm-kg.ai/book/aio.json (the orderability chapter)\n- https://investors.kaiseraluminum.com/stock-data/analyst-coverage (coverage)\n- https://mcp.us-cm-kg.ai/record/NASDAQ/KALU (the record)\n",
