First Interstate Bank celebrates $100 million in giving at local open houses. * Anthony Kutzler First Interstate Bank Communications Specialist * 1 hr ago First Interstate Bank marked a milestone 35 years in the making this week, celebrating $100 million in total philanthropic giving by the bank and the First Interstate BancSystem Foundation at Community Open House events held across every branch on April 21. What began in 1990 with six grants totaling $47,500 has grown into one of the region's most significant community investment platforms, contributing more than $7 million in 2024 alone. Programs span financial literacy, youth development, disaster relief, and nonprofit capacity building. Since 2022, the bank's employee-driven Believe in Local campaign has invested $4 million in grassroots nonprofits. Its Coats & More program has distributed more than 80,400 coats and warm items since 2009, Neighbors Feeding Neighbors has contributed $2.7 million over 15 years, and employees logged more than 60,000 volunteer hours in 2025. "Without strong communities, you can't have a strong bank," said First Interstate President and CEO Jim Reuter. "This milestone is a meaningful moment for us as we lean in to ensure our clients and communities are taken care of."

Net interest margin edged up to 3.38%, whilst criticized loans and non-performing assets declined, though net charge-offs increased to $22.1 million. Management repurchased approximately $118 million of stock in 2025 and added $150 million to its buyback authorisation.
