High Risk (D) — Insolar Honesty Grade

Lumio was formed in 2021 from the consolidation of multiple regional solar installers and rapidly became one of the largest residential solar companies in the U.S. The merger integration has produced significant customer-experience volatility, with documented complaint patterns around dealer-network sales practices inherited from the legacy entities. Lumio filed for Chapter 11 bankruptcy in September 2024.
