A press release announcing the completion is attached to the 8-K as Exhibit 99.1.

Key Details

• 138 branches acquired from BMO Bank N.A.
• Transaction effective date: September 4, 2026.
• Branch locations span the Midwest, Great Plains and West regions of the U.S.
• The 8-K includes the press release (Exhibit 99.1); it does not disclose financial terms or the acquisition’s financial impact.

Why It Matters
The filing confirms the transaction is complete and the company has expanded its branch network into new geographic regions. Because the 8-K does not provide deal terms or financial estimates, investors should watch for follow-up filings and company communications for details on financial effects, integration plans, or changes to deposits, loans, and operating results.
