First Interstate BancSystem: Co-CBO Lorrie Asker steps down, Chris Shepler named sole CBO

Neutral Impact 3 of 5 leadership Written later

First Interstate BancSystem said Executive Vice President and Co-Chief Banking Officer Lorrie Asker stepped out of that role effective November 14, 2025, moving to an executive advisor role to the CEO through the end of the first quarter of 2026. Chris Shepler, the other Co-CBO, was appointed sole Chief Banking Officer under a new employment agreement with a $480,000 base salary. The change consolidates banking leadership under one executive, and the filing does not discuss financial results.
