Business Combination, Asset Acquisition, Transaction between Entities under Common Control, and Joint Venture Formation [Abstract]        
Business Combination, Pro Forma Information    
The following unaudited pro forma consolidated financial information reflects the results of operations of the Company for the three and six months ended June 30, 2026 and 2025, as if the Merger had been completed on January 1, 2025. Pro forma adjustments reflect changes in interest income from the accretion of discounts and premiums on acquired loans, changes in interest expense from amortization or accretion of fair value adjustments on interest-bearing deposits, and the amortization of the core deposit intangibles as if the deposits had been acquired on January 1, 2025. These pro forma results have been prepared for illustrative purposes only and are based on estimates and assumptions that have been made solely for purposes of
developing such pro forma information and are not necessarily indicative of what the Company’s operating results would have been, had the Merger actually taken place at the beginning of the previous annual period. The amounts do not reflect anticipated operating cost savings, revenue enhancements, or other synergies expected to result from the Merger. Actual results may differ from the unaudited pro forma information presented.
