Standing is from the Colorado Secretary of State as of August 3, 2026: In good standing and “Exists” are both current statuses; Delinquent most commonly follows a missed Periodic Report (other causes exist — see the delinquency guide), usually fixable in one sitting; means the company has no row in the current Secretary of State pull.
