Colorado · 2025-2026
Comparing the 2025-2026 filings against 2024-2025. A client on the books then and absent now has gone — states publish who is registered, never who left.
The first two tables cover filers registered in both periods, so a number there is business won or lost. Those who arrived or left altogether are counted separately below, because a newcomer with forty clients has not taken them from anyone.
A large loss is sometimes a merger or a renamed firm rather than lost business — worth checking the firm's own page before drawing a conclusion.
Not registered in 2024-2025 at all, and arriving with this many clients.
Registered in 2024-2025 and absent from 2025-2026 entirely — retired, moved state, or wound up.
