Its security type is Corporate and its sector is 4911 Electric Services. Its jurisdiction is United States, Colorado. Its segment is not on the record. Its listing status is listed, not halted.\n\n## The disclosure read\n\nThe record holds 69 filings in the twelve months to 2026-11-08, across 48 filing days. The median gap between filing days is 4 days. The latest filing is dated 2026-10-08 and is of type corporate_news, 31 days before the record date. The exchange median is 6.0 days of cadence gap, 52 filings and 5.0 days of latency across 4359 issuers on NASDAQ.

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 halt flag reads listed, not halted.\n\n## Orderability\n\nThe outcome is not determinable, because 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.
