Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Accounting	In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly the financial results for the periods presented, and all such adjustments are of a normal recurring nature. All material intercompany transactions are eliminated. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the entire year. These interim consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission and, therefore, certain information and footnote disclosures normally presented in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) have been omitted or abbreviated. These interim financial statements should be read in conjunction with the audited consolidated financial statements and footnote disclosures for the Company’s previously filed Form 10-K for the year ended December 31, 2025.
Use of Estimates	Preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future. Critical accounting estimates that are particularly susceptible to significant change for the Company include the determination of the acquired loans, allowance for credit losses and purchase accounting adjustments (other than loans). Other estimates include goodwill, fair value of financial instruments, investment securities and the assessment of income taxes. Management does not anticipate any material changes to estimates in the near term. Factors that may cause sensitivity to the aforementioned estimates include but are not limited to: external market factors such as market interest rates and employment rates, changes to operating policies and procedures, economic conditions in the Company’s markets, and changes in applicable banking regulations. Actual results may ultimately differ from estimates.
Accounting Standards Adopted in Current Period and Accounting Standards Not Yet Adopted	Accounting Standards Adopted in Current Period ASU 2025-08, "Financial Instruments – Credit Losses (Topic 326), Purchased Loans.” The updates in ASU 2025-08 amend the guidance in ASC 326 on the accounting for certain purchased loans. Under the ASU, entities must account for acquired loans (excluding credit cards) that meet certain criteria at acquisition (“purchased seasoned loans”) by recognizing them at their purchase price plus an allowance for expected credit losses (i.e., the gross-up approach). All non-purchased credit deteriorated (“non-PCD”) loans (excluding credit cards) that are acquired in a business combination are deemed seasoned. Other non-PCD loans (excluding credit cards) are seasoned if they were purchased at least 90 days after origination and the acquirer was not involved in the origination of the loans. The ASU’s amendments align the accounting for purchased seasoned loans with the treatment of financial assets purchased with more-than-insignificant credit deterioration since origination (“PCD assets”). The Company early adopted the amendments effective January 1, 2026, on a prospective basis. The Progressive acquisition disclosures contained in Note 2, as well as the allowance measurements reflected in Note 5 incorporate the updated guidance. Accounting Standards Not Yet Adopted None

Fair Value Measurement	Fair Value Disclosures The Company groups its financial assets and liabilities measured at fair value in three levels. Fair value should be based on the assumptions market participants would use when pricing the asset or liability and establishes a fair value hierarchy that prioritizes the inputs used to develop those assumptions and measure fair value. The hierarchy requires companies to maximize the use of observable inputs and minimize the use of unobservable inputs. The three levels of inputs used to measure fair value are as follows: •Level 1 – Includes the most reliable sources and includes quoted prices in active markets for identical assets or liabilities. •Level 2 – Includes observable inputs. Observable inputs include inputs other than quoted prices that are observable for the asset or liability (for example, interest rates and yield curves at commonly quoted intervals, volatilities, prepayment speeds, loss severities, credit risks, and default rates) as well as inputs that are derived principally from or corroborated by observable market data by correlation or other means (market-corroborated inputs). •Level 3 – Includes unobservable inputs and should be used only when observable inputs are unavailable. Recurring Basis Fair values of investment securities available for sale were primarily measured using information from a third-party pricing service. This pricing service provides information by utilizing evaluated pricing models supported with market data information. Standard inputs include benchmark yields, reported trades, broker/dealer quotes, issuer spreads, benchmark securities, bids, offers, and reference data from market research publications. The fair values of mortgage loans held for sale are based on commitments on hand from investors within the secondary market for loans with similar characteristics. Nonrecurring Basis The Company has segregated all financial assets and liabilities that are measured at fair value on a nonrecurring basis into the most appropriate level within the fair value hierarchy based on the inputs used to determine the fair value at the measurement date in the table below. The Company did not record any liabilities at fair value for which measurement of the fair value was made on a nonrecurring basis. The fair value of the individually evaluated loans is measured at the fair value of the collateral for collateral-dependent loans. Individually evaluated loans are Level 3 assets measured using appraisals from external parties of the collateral less any prior liens and adjusted for estimated selling costs. Adjustments may be made by management based on a customized internally developed discounting matrix. Repossessed assets are initially recorded at fair value less estimated cost to sell, which is generally 10%. The fair value of repossessed assets is based on property appraisals and an analysis of similar properties available. As such, the Bank records repossessed assets as Level 3. Fair Value of Financial Instruments The fair value of a financial instrument is the current amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. In accordance with GAAP, certain financial instruments and all non-financial instruments are excluded from these disclosure requirements. Accordingly, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company. The following methods and assumptions were used to estimate the fair value of each class of financial instruments for which it is practicable to estimate that value: Cash and Short-Term Investments – For those short-term instruments, the carrying amount is a reasonable estimate of fair value. Securities Purchased Under Agreements to Resell - The carrying amount approximates its fair value. Securities – Fair value of securities is based on quoted market prices. If a quoted market price is not available, fair value is estimated using quoted market prices for similar securities. Loans – The fair value for loans is estimated using discounted cash flow analyses, with interest rates currently being offered for similar loans to borrowers with similar credit rates. Loans with similar classifications are aggregated for purposes of the calculations. The allowance for loan losses, which was used to measure the credit risk, is subtracted from loans. Cash Value of Bank-Owned Life Insurance (“BOLI”) – The carrying amount approximates its fair value. Other Equity Securities – The carrying amount approximates its fair value. Interest Rate Swaps - Market values are obtained from market pricing data sources available for comparable transactions in the over-the-counter derivative market. Deposits – The fair value of demand deposits and certain money market deposits is the amount payable at the reporting date. The fair value of fixed-maturity certificates of deposit is estimated using discounted cash flow analyses, with interest rates currently offered for deposits of similar remaining maturities. Borrowings – The fair value of FHLB advances and other long-term borrowings is estimated using the rates currently offered for advances of similar maturities. The carrying amount of short-term borrowings maturing within ninety days approximates the fair value. Commitments to Extend Credit and Standby and Commercial Letters of Credit – The fair values of commitments to extend credit and standby and commercial letters of credit do not differ significantly from the commitment amount and are therefore omitted from this disclosure.
