Bank of the Cascades roughly doubled to $2.4 billion in assets when it bought Nampa-based Home Federal in 2014. The acquisition was part of a 13-month consolidation frenzy when nine of the 21 banks operating in the Treasure Valley bought, or were sold to, another bank. Experts at the time expected increasing regulation would spur more consolidation, but merger activity stopped until now.
Cascade Bancorp shareholders will receive about 0.15 shares of First Interstate stock and $1.91 in cash per share.
