R R Evans Foundation Inc

Enterprise Holdings Foundation

Saint Louis, MO

The Enterprise Holdings Foundation supports charitable and educational nonprofits in communities where Enterprise Mobility operates, focusing on health, education, arts, and disaster relief; applicants must be actively supported by an Enterprise Mobility team member, spouse, or domestic partner. Giving varies widely: it reported 9,499 grants in 2024, but its 2025 filing showed one grant of $101.4 million, so that amount is not a typical award. Applications are accepted at any time through eligible Enterprise-affiliated applicants; the Foundation does not limit giving to preselected organizations.
