1st Source Corporation is an Indiana-based bank holding company (founded 1971) headquartered in South Bend that operates primarily through 1st Source Bank. The company combines a community/regional banking footprint (78 banking centers across Indiana, Michigan and Sarasota County, Florida) with a nationwide Specialty Finance Group that originates and services equipment, aircraft, and fleet vehicle loans and leases. In addition to traditional deposit and lending products, it provides trust and wealth advisory services and operates an insurance agency subsidiary. The business model is relationship-driven, with revenue largely tied to net interest income from loans/leases and fee income from wealth, insurance, and service activities.
