WM Ticker
Goodwill Industries International is a leading social enterprise nonprofit powered by a network of 150 high-performing local Goodwill organizations across North America. Together, we operate at scale by advancing resale, workforce development, and circular solutions through shared systems and local execution. We are America’s neighbor: 83% of the U.S. population resides within ten miles of their local Goodwill. Donated goods power the Goodwill resale engine, generating revenue that is reinvested into localized workforce development programs — the core of our work. At the same time, our circular resale solutions support sustainability by extending product life, diverting billions of pounds of materials from landfills annually, and building greater transparency and accountability across reuse.
