Don't confuse not-for-profit with not making a profit. NFP only means that the organization complies with specific IRS requirements and gains the benefit of being tax exempt. They need to justify that they are providing a "public good." Much of this is outlined in their public document - the IRS 990 report
NFP organizations can be very profitable. And directors can receive substantial monetary benefits.
However, there are no shareholders and the equity is not owned by individuals.
