Its security type is Corporate and its sector is 4911 Electric Services. Its jurisdiction is United States, Minnesota. Its segment is not on the record. Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 59 filings in the twelve months to 2026-11-08, across 29 filing days. The median gap between filing days is 5.0 days. The latest filing is dated 2026-11-04 and is of type results, 4 days before the record date.

The record holds no auditor changes.\n\n## Events and halts\n\nThe record holds no listing, delisting, name change or segment move lines.

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. 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, with the chapter as of 2026-11-04.\n\n## Coverage\n\nNo research houses were found on the issuer's own investor-relations page.\n\n## Open research\n\nNo openly published research notes were found.\n\n## Licensed\n\nLicensed research: none loaded.
