Is REI public or private?

Could you please clarify for me whether REI is a publicly traded company or a privately held entity? I'm trying to understand the ownership structure and potential investment opportunities associated with this organization. Additionally, if REI is publicly traded, could you provide some insight into its stock performance and any notable financial milestones it has achieved in recent years? Alternatively, if REI is privately held, could you elaborate on its funding sources and any notable investors that have backed the company? Thank you for your assistance in clarifying this matter.
