1ST SOURCE CORP

Our headquarters building is located in downtown South Bend, Indiana. The building is part of a larger complex, including a 300-room hotel and a 500-car parking garage. Our lease on this property runs through December 2029 for the 7th floor and September 2027 for all remaining floors. As of December 31, 2025, 1st Source leases approximately 83% of the office space in this complex.

At December 31, 2025, we owned or leased properties where our 78 banking centers were located. Our facilities are located in Allen, DeKalb, Elkhart, Fulton, Hamilton, Huntington, Kosciusko, LaPorte, Marshall, Porter, Pulaski, St. Joseph, Starke, Tippecanoe, Wells, and Whitley Counties in the State of Indiana, Berrien, Cass, and Kalamazoo Counties in the State of Michigan, and Sarasota County in the state of Florida. 1st Source Bank also owns approximately 28 acres in St. Joseph County which were approved by the Board for development and construction of an operations and training facility. During 2024 we sold approximately seven acres of land that was not part of the 28 acres approved by the Board for development and construction. We anticipate moving forward with construction in the coming years subject to receiving appropriate agreements, approvals and authorizations from local city and county building and economic development authorities as well as market conditions including inflation levels and financing costs. Additionally, we utilize an operations center for business operations. The Bank leases additional properties to and from third parties under arms-length agreements.
