1. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited consolidated financial statements of the Company were prepared in accordance with GAAP for interim financial information, general practices within the financial services industry, and instructions for Form 10-Q and Regulation S-X. Accordingly, these interim financial statements do not include all of the information or footnotes required by GAAP for annual financial statements. However, in the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair presentation of the financial statements have been included. The results of operations for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for the entire fiscal year. These statements should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto for the year ended December 31, 2025, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

Certain prior period amounts have been reclassified to conform to the current period presentation. These changes in presentation did not have a material impact on the Company’s financial condition or results of operations.

Critical Accounting Policies and Estimates

In preparing the financial statements, the Company is required to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. The financial statements reflect all adjustments that are, in the opinion of management, necessary for a fair statement of the Company’s financial condition, results of operations, comprehensive income, changes in stockholders’ equity, and cash flows for the interim period presented. These adjustments are of a normal recurring nature and include appropriate estimated provisions.

Accounting Standards Adopted in 2026

ASU No. 2025-08, Financial Instruments - Credit Losses (Topic 326): Purchased Loans. The guidance issued in this update was designed to improve the decision usefulness of the financial reporting for acquired financial assets. This amendment allows the gross‑up method to apply to certain non‑PCD loans acquired in a business combination that qualify as purchased seasoned loans. These loans are now accounted for the same as PCD loans, with an ACL established at acquisition and recorded through a gross‑up to the loan’s amortized cost basis. This standard is effective for all entities for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. The amendments in this update should be applied prospectively to loans that are acquired on or after the initial application date. Early adoption is permitted in an interim or annual reporting period in which financial statements have not been issued. The Company adopted this standard on January 1, 2026. Adoption of this ASU did not have an impact on the Company’s consolidated financial statements.

Recent Accounting Pronouncements

ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40). The guidance issued in this update was designed to improve financial reporting by requiring entities to disclose additional information about specific expense categories in the notes to financial statements. This standard is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The amendments in this update should be applied either prospectively to financial statements issued for reporting periods after the effective date of this update or retrospectively to any or all prior periods presented in the financial statements. The Company does not expect the adoption of this guidance to have a material impact on the Company’s consolidated financial statements.

2. Securities

Securities are classified as AFS, HTM, and equity securities. Total securities were $720.4 million as of September 30, 2026.

Securities AFS and Securities HTM

Securities AFS and securities HTM are debt securities. Securities AFS are held for indefinite periods of time and are carried at estimated fair value. As of September 30, 2026, the estimated fair value of securities AFS was $601.6 million. The net unrealized loss on securities AFS increased $19.6 million for the nine months ended September 30, 2026, resulting in a net unrealized loss of $62.8 million as of September 30, 2026.

Securities HTM, which the Company has the intent and ability to hold until maturity, are carried at amortized cost. As of September 30, 2026, the amortized cost of securities HTM was $115.9 million.

Investment activity for the nine months ended September 30, 2026, included $93.0 million in maturities, principal repayments, and calls, and $2.0 million in sales, partially offset by $62.1 million of securities purchased. There wereno purchases or sales of securities HTM for the same period.

The amortized cost and estimated fair value of securities AFS and securities HTM are summarized in the following tables:

The amortized cost and estimated fair value of securities AFS and securities HTM as of September 30, 2026, by contractual maturity, are shown below. Expected maturities may differ from contractual maturities because issuers have the right to call or repay obligations with or without call or prepayment penalties.

Accounting for Credit Losses – Securities AFS and Securities HTM

The Company evaluates securities AFS for impairment when there has been a decline in fair value below the amortized cost basis of a security to determine whether there is a credit loss associated with the decline in fair value on at least a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. Due to the zero credit loss assumption and the evaluation of the considerations applied to the securities AFS, there wasno ACL recorded for securities AFS as of September 30, 2026 and December 31, 2025. Also, as part of the Company’s evaluation of its intent and ability to hold investments for a period of time sufficient to allow for any anticipated recovery in the market, the Company considers its investment strategy, cash flow needs, liquidity position, capital adequacy, and interest rate risk position. Management does not intend to sell these securities, and it is more likely than not that the Company will not have to sell these securities before each security has recovered its amortized cost basis.

Due to the zero credit loss assumption on the securities HTM portfolio, there wasno ACL recorded for securities HTM as of September 30, 2026 and December 31, 2025.

For securities AFS and securities HTM, accrued interest receivable totaled $3.0 million and $3.2 million as of September 30, 2026 and December 31, 2025, respectively, and was reported in accrued interest receivable on the accompanying consolidated balance sheets.

Information pertaining to securities AFS with gross unrealized losses as of September 30, 2026 and December 31, 2025, aggregated by investment category and length of time that individual securities have been in a continuous loss position, is described as follows:

As of September 30, 2026, the Company held 539 securities AFS that were in unrealized loss positions. The aggregate unrealized loss of these securities AFS as of September 30, 2026, was 9.50% of the amortized cost basis of securities AFS.

The proceeds from sales and calls of debt securities and their gross gain (loss) for the three and nine months ended September 30, 2026 and 2025, are presented in the table below:

(1)The proceeds include the gross gain and loss.

Equity Securities

Equity securities are an investment in a CRA mutual fund, consisting primarily of bonds. Equity securities are carried at fair value on the consolidated balance sheets with periodic changes in value recorded through the consolidated statements of income. As of September 30, 2026, equity securities had a fair value of $2.9 million with a recognized loss of $144,000 for the nine months ended September 30, 2026. As of December 31, 2025, equity securities had a fair value of $3.0 million with a recognized gain of $94,000 for the year ended December 31, 2025.

Pledged Securities

Securities with carrying values of approximately $208.2 million and $228.0 million were used as collateral as of September 30, 2026 and December 31, 2025, respectively.

3. Loans and Asset Quality

The following table presents the aging analysis of the past due loans and loans 90 days or more past due and still accruing interest by loan category as of December 31, 2025:

Loan Modifications

Modifications are made to a borrower experiencing financial difficulty, and the modified terms are in the form of principal forgiveness, interest rate reduction, other-than-insignificant payment delay, or a term extension in the current reporting period. For the periods ended September 30, 2026 and 2025, modifications were made to certain borrowers by granting term extensions. These term extensions were not significant to the consolidated financial statements.

Credit Quality Indicators

Loans are categorized based on the degree of risk inherent in the credit and the ability of the borrower to service the debt. A description of the general characteristics of the Bank’s risk rating grades follows:

Pass - These loans are of satisfactory quality and do not require a more severe classification.

Special mention - This category includes loans with potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan. However, the loss potential does not warrant substandard classification.

Substandard - Loans in this category have well-defined weaknesses that jeopardize normal repayment of principal and interest. Prompt corrective action is required to reduce exposure and to assure adequate remedial actions are taken by the borrower. If these weaknesses do not improve, loss is possible.

Doubtful - Loans in this category have well-defined weaknesses that make full collection improbable.

Loss - Loans classified in this category are considered uncollectible and charged-off to the ACL.

As of September 30, 2026, the Company hadno loans classified as doubtful or loss. The following table summarizes loans by risk rating and year of origination as of September 30, 2026, and gross charge-offs for the nine months ended September 30, 2026:

As of December 31, 2025, the Company hadno loans classified as doubtful or loss. The following table summarizes loans by risk rating and year of origination as of December 31, 2025, and gross charge-offs for the year ended December 31, 2025:

Commitments to Extend Credit

Commitments to extend credit are agreements to lend to a customer if all conditions of the commitment have been met. Commitments generally have fixed expiration dates or other termination clauses and may require the payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if it is deemed necessary by the Company upon extension of credit, is based on management’s evaluation of the customer’s ability to repay. As of September 30, 2026 and December 31, 2025, unfunded loan commitments totaled approximately $593.2 million and $545.7 million, respectively.

Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing, and similar transactions. As of September 30, 2026 and December 31, 2025, commitments under standby letters of credit totaled approximately $14.7 million and $14.5 million, respectively. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers.

The Company estimates expected credit losses for unfunded commitments over the contractual period in which the Company is exposed to credit risk through a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The reserve for unfunded commitments is recorded within accrued expenses and other liabilities on the consolidated balance sheets, and the related provision is recorded in provision for credit losses on the consolidated statements of income. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. The loss rates computed for each pool and expected pool-level funding rates are applied to the related unfunded commitment balance to obtain the reserve amount. As of September 30, 2026 and December 31, 2025, the reserve on unfunded commitments was $642,000.

The following table summarizes the reserve for unfunded commitments for the periods indicated:

4. Deposits

Deposits were $2.96 billion as of September 30, 2026 and December 31, 2025. The $1.9 million decrease was impacted by the seasonal outflow of funds from public entity customers and customer income tax payments and offset by higher commercial deposit balances. Deposits are summarized below:

Collateral for Deposits

As of September 30, 2026 and December 31, 2025, securities and FHLB letters of credit with values of approximately $213.1 million and $302.4 million, respectively, were pledged as collateral to secure public entity deposits.

5. Other Borrowed Funds

The Company has established borrowing capacity with the FHLB, the Federal Reserve Bank’s Discount Window facility, and other correspondent banks to provide additional sources of operating funds. As of September 30, 2026 and December 31, 2025, the Company hadno outstanding borrowings under these agreements.

6. Contingencies

The Company and the Bank are involved, from time to time, in various legal matters arising in the ordinary course of business. While the outcome of these claims or litigation cannot be determined at this time, in the opinion of management, neither the Company nor the Bank are involved in such legal proceedings that the resolution is expected to have a material adverse effect on the consolidated results of operations, financial condition, or cash flows.

7. Fair Value

The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.

Fair Value Disclosure

Securities AFS, loans HFS, and equity securities are recorded at fair value on a recurring basis. Additionally, the Company may be required to record at fair value other assets on a nonrecurring basis, such as collateral dependent loans, foreclosed assets, and certain other assets. The nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets.

ASC 820, Fair Value Measurements and Disclosures indicates that assets and liabilities are recorded at fair value according to a fair value hierarchy comprised of three levels:

•Level 1 pricing represents quotes on the exact financial instrument that is traded in active markets. Quoted prices on actively traded equities, for example, are in this category.

•Level 2 pricing is derived from observable data including market spreads, current and projected rates, prepayment data, and credit quality. The valuation may be based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.

•Level 3 pricing is derived without the use of observable data. In such cases, mark-to-model strategies are typically employed. Often, these types of instruments have no active market, possess unique characteristics, and are thinly traded.

The Company used the following methods and significant assumptions to estimate fair value:

Securities AFS and Equity Securities: The fair values for securities AFS are determined by quoted market prices, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3).

Loans HFS: Residential mortgage loans originated and held for sale are carried at the lower of cost or estimated fair value on an individual basis. The fair values of mortgage loans HFS are based on commitments on hand from investors within the secondary market for loans with similar characteristics. As such, the fair value adjustments for mortgage loans HFS are recurring Level 2.

Loans HFI: The Company does not record loans HFI at fair value on a recurring basis. Loans for which it was probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are evaluated individually to determine if any credit loss exists. For loans evaluated on an individual basis that are collateral dependent, the fair value is estimated by applying a discount factor to the collateral value then deducting the estimated cost to sell. For loans evaluated on an individual basis that are not collateral dependent, the discounted cash flow method is utilized to determine the fair value. When a loan experiences a credit loss with specific allocated losses determined by the fair value method, the Company considers the collateral dependent loan as nonrecurring Level 3.

Foreclosed Assets: Foreclosed assets, consisting of properties obtained through foreclosure or in satisfaction of loans, are reported at fair value, determined on the basis of current appraisals, comparable sales, and other estimates of value obtained principally from independent sources and adjusted for estimated selling costs (Level 2). However, foreclosed assets are considered Level 3 in the fair value hierarchy because management has qualitatively applied a discount due to the size, supply of inventory, and the incremental discounts applied to the appraisals. Management also considers other factors, including changes in absorption rates, length of time the property has been on the market, and anticipated sales values, which have resulted in adjustments to the collateral value estimates indicated in certain appraisals.

Fair Value of Assets Measured on a Recurring Basis

The table below presents the recorded amount of assets measured at fair value on a recurring basis:

There were no transfers between Level 1, 2, or 3 during the nine months ended September 30, 2026 or the year ended December 31, 2025.

Fair Value of Assets and Liabilities Measured on a Nonrecurring Basis

Financial Assets and Financial Liabilities: Certain financial assets and financial liabilities are measured at fair value on a nonrecurring basis and are subject to fair value adjustments in certain circumstances. Financial assets measured at fair value on a nonrecurring basis include certain individually evaluated collateral dependent loans reported at fair value of the underlying collateral if repayment is expected solely from the collateral. Prior to foreclosure of these loans, fair value of the collateral is estimated using Level 3 inputs based on customized discounting criteria.

The table below presents certain collateral dependent loans that were remeasured and reported at fair value through the ACL based upon the fair value of the underlying collateral as of the dates indicated:

The Company had no financial liabilities measured at fair value on a nonrecurring basis as of September 30, 2026 and December 31, 2025.

Nonfinancial Assets and Liabilities: Certain nonfinancial assets and nonfinancial liabilities are measured at fair value on a nonrecurring basis. These include certain foreclosed assets, which are remeasured and reported at fair value through a charge-off to the ACL upon initial recognition as a foreclosed asset. Subsequent to their initial recognition, certain foreclosed assets are remeasured at fair value through an adjustment included in other noninterest income. The fair value of foreclosed assets is estimated using Level 3 inputs based on customized discounting criteria less estimated selling costs.

The following table presents foreclosed assets that were remeasured and reported at fair value as of the dates indicated:

There were no foreclosed assets that were remeasured subsequent to initial recognition as of September 30, 2026 and December 31, 2025.

The Company had no nonfinancial liabilities measured at fair value on a nonrecurring basis as of September 30, 2026 and December 31, 2025.

The unobservable inputs used for the Level 3 fair value measurements on a nonrecurring basis were as follows:

Fair Value of Financial Instruments

The carrying amounts and estimated fair values of financial instruments as of September 30, 2026 and December 31, 2025, were as follows:

8. Regulatory Capital Requirements

The Company and the Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory, and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s and the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies.

Basel III Capital Requirements

The Company and the Bank are subject to Basel III capital guidelines. Basel III requires the Company and the Bank to maintain certain minimum ratios to meet capital adequacy requirements. It is management’s belief that, as of September 30, 2026, both the Company and the Bank met all capital adequacy requirements under Basel III. Management expects that the capital ratios for the Company and the Bank under Basel III will continue to exceed capital adequacy requirements. Management believes that, as of September 30, 2026, the Bank is well-capitalized under the regulatory framework for prompt corrective action.

Capital amounts and ratios for the Company as of September 30, 2026 and December 31, 2025, are presented in the following table (Basel III Minimum includes the capital conservation buffer):

Capital amounts and ratios for the Bank as of September 30, 2026 and December 31, 2025, are presented in the following table (Basel III Minimum includes the capital conservation buffer):

(1)This column refers to the prompt corrective action requirements applicable to banks.

Community Bank Leverage Ratio Framework

As part of the Economic Growth Act, an optional CBLR framework is available to the Company and the Bank as an alternative to the Basel III risk-based capital framework. The CBLR framework provides for a simple measure of capital adequacy for certain community banking organizations. Specifically, depository institutions and depository institution holding companies that have less than $10.0 billion in total consolidated assets and meet other qualifying criteria, including a Tier 1 leverage ratio of greater than 9.00%, are considered qualifying community banking organizations eligible to opt into the CBLR framework and replace the applicable Basel III risk-based capital requirements. In April 2026, the federal banking agencies issued a final rule that, among other things, lowered the 9.00% leverage ratio requirement to 8.00%.

As of September 30, 2026, the Company and the Bank qualify for the CBLR framework. Management does not intend to utilize the CBLR framework.

9. Equity

Stock Repurchases

On December 18, 2025, the Company’s board of directors approved the renewal and increase of the 2025 stock repurchase program that expired on December 31, 2025. The renewed and increased 2026 stock repurchase program authorizes the Company to purchase up to $10.0 million of its outstanding shares of common stock from January 1, 2026 through December 31, 2026. Repurchases may be made from time to time in the open market at prevailing prices and based on market conditions, or in privately negotiated transactions.

For the three and nine months ended September 30, 2026, the Company didnot repurchase any shares of its common stock under the stock repurchase program. As of September 30, 2026, the Company had $10.0 million available for repurchasing its common stock under the 2026 stock repurchase program.

Effective January 1, 2023, stock repurchases are subject to a nondeductible excise tax under the Inflation Reduction Act of 2022 equal to 1.0% of the fair market value of the shares repurchased, subject to certain limitations.

AOCI - Transfer of Unrealized Gain (Loss) of Securities AFS and HTM

In 2022, the Company reclassified $166.3 million, net of $17.9 million of unrealized loss, from securities AFS to securities HTM. The securities were transferred at fair value, which became the cost basis for the securities HTM. At the date of the transfer, the net unrealized loss of $17.9 million, of which $14.2 million, net of tax, was included in AOCI and is being amortized over the remaining life of the securities as a yield adjustment, in a manner consistent with the amortization or accretion of the original purchase premium or discount on the associated security. There were no gains or losses recognized as a result of the transfer. As of September 30, 2026, the net unamortized, unrealized loss remaining on the transferred securities included in the consolidated balance sheets totaled $10.7 million, of which $8.5 million, net of tax, was included in AOCI.

10. Earnings Per Common Share

Basic EPS is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period, after giving retroactive effect to stock splits. Diluted EPS includes accrued but unissued shares relating to the Director Compensation Program, stock options, and restricted stock determined using the treasury stock method. The dilutive EPS calculation assumes all outstanding stock options to purchase common stock have been exercised at the beginning of the year, and the pro forma proceeds from the exercised options and restricted stock are used to purchase common stock at the average fair market valuation price.

The computations of basic and diluted earnings per common share for the Company were as follows:

11. Segment Reporting

The Company is engaged primarily in providing a fully integrated suite of banking products and services consistently across all of its markets. The CODM assesses performance and decides how to allocate resources based on net income as reported in the accompanying consolidated statements of income. While the CODM monitors the revenue streams of the various banking products, services, and markets, banking operations are managed and financial performance is evaluated on a company-wide basis. Accordingly, all of the Company’s banking operations are considered by management to be aggregated inone reportable operating segment.

Financial results for the banking operations segment are presented in the table below:

Banking operations segment assets were $3.37 billion and $3.35 billion as of September 30, 2026 and December 31, 2025, respectively.
