NOTES TO INTERIM CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
(Dollars in thousands except per share amounts)
Note 1 – Significant Accounting Policies
BASIS OF PRESENTATION AND CONSOLIDATION: As used in these notes, as well as in Management's Discussion and Analysis of Financial Condition and Results of Operations, references to “we,” “our,” “us,” and “the Corporation” refer to Isabella Bank Corporation, a Michigan corporation and registered financial holding company, our wholly-owned banking subsidiary, Isabella Bank, and our other consolidated subsidiaries. References to the “Bank” refer to Isabella Bank.
The accompanying unaudited interim condensed consolidated financial statements in this Quarterly Report on Form 10-Q for the three and six-month periods ended June 30, 2025 (this “Form 10-Q”) have been prepared in accordance with GAAP for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. In our opinion, all adjustments considered necessary for a fair presentation have been included. Operating results for the three and six-month periods ended June 30, 2025 are not necessarily indicative of the results that may be expected for the year ending December 31, 2025. For further information, refer to our Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the SEC on March 12, 2025 (the “2024 Annual Report on Form 10-K”).
OPERATING SEGMENTS: Segment information is prepared on the same basis that our CEO, who is our Chief Operating Decision Maker (“CODM”), manages our segments, evaluates financial results, and makes key operating decisions. While the CODM monitors the revenue streams of our various products and services, operations are managed, and financial performance is evaluated on a corporate-wide basis. Operating segments are aggregated into one as operating results for all segments are similar. Accordingly, all of the banking-related operations are considered by management to be aggregated in one reportable operating segment.
The segment is also distinguished by the level of information provided to the CODM, who uses such information to review performance of various components of the business, which are then aggregated if operating performance, products and services, and geographical regions are similar. The CODM will evaluate the financial performance of our business components by evaluating revenue streams, significant expenses, and budget to actual results in assessing our reportable segment and in the determination of allocating resources. Further, the CODM uses revenue streams to evaluate product pricing and significant expenses to assess performance and evaluate return on assets.
Consolidated net income is used to benchmark results against our competitors. Benchmarking and monitoring of budget to actual results are used in assessment performance and in establishing compensation. Revenue from banking operations consists primarily of loan and investment interest, deposit related fees, and wealth fees. Interest expense, provision for credit losses, compensation, and occupancy and equipment costs provide the significant expenses in our banking operations. All operations are domestic.
RECLASSIFICATIONS: Certain amounts reported in the interim 2024 consolidated financial statements have been reclassified to conform with the 2025 presentation. Additionally, certain amounts reported as commercial and industrial loans have been reclassified as commercial real estate loans to conform to the June 30, 2025 presentation. Our accounting policies are materially the same as those discussed in Note 1 to the Consolidated Financial Statements included in our 2024 Annual Report on Form 10-K.

Expected maturities for government sponsored enterprises and states and political subdivisions may differ from contractual maturities as issuers may have the right to call or prepay obligations.
As the auction rate money market preferred investments have continual call dates, they are not reported by a specific maturity group. Because of their variable monthly payments, mortgage-backed securities and collateralized mortgage obligations are not reported by a specific maturity group.

Number of securities in an unrealized loss position:175 178 353 
As of June 30, 2025, no ACL has been recognized on AFS securities in an unrealized loss position, as management does not believe any of the securities are impaired due to reasons of credit quality. This is based on our analysis of the underlying risk characteristics, including credit ratings, and other qualitative factors related to our AFS securities and consideration of our historical credit loss experience and internal forecasts. The issuers of these securities continue to make timely principal and interest payments under the contractual terms of the securities. Management does not currently intend to sell any of the securities classified as AFS in the table above, and believes it is more likely than not that we will not have to sell any such securities before a recovery of cost. The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the securities approach their respective maturity date or repricing date, or if the market yields for such investments decline.

We grant commercial, agricultural, residential real estate, and consumer loans to customers primarily in Bay, Clare, Gratiot, Isabella, Mecosta, Midland, Montcalm, and Saginaw counties in Michigan. The ability of borrowers to honor their repayment obligations is often dependent upon the real estate, agricultural, manufacturing, retail, gaming, tourism, health care, higher education, and general economic conditions of this region. Substantially all of our consumer and residential real estate loans are secured by various items of property, while commercial loans are secured primarily by real estate, business assets, and personal guarantees. A small portion of loans are unsecured.
Loans that we have the intent and ability to hold in our portfolio are reported at their outstanding principal balance adjusted for any charge-offs, the ACL, and deferred fees or costs. Unless a loan has a nonaccrual status, interest income is accrued over the term of the loan based on the principal amount outstanding. Loan origination fees and certain direct loan origination costs are capitalized and recognized as a component of interest income over the term of the loan using the appropriate amortization method. Net unamortized deferred loan costs were $3,268 and $3,330 at June 30, 2025 and December 31, 2024, respectively.
Commercial and agricultural loans include loans for commercial real estate, commercial operating loans, advances to mortgage brokers, farmland and agricultural production, and loans to states and political subdivisions. Repayment of these loans is dependent upon the successful operation and management of a business. We minimize our risk by limiting the amount of direct credit exposure to any one borrower to $18,000. Borrowers with direct credit needs of more than $18,000 may be serviced through the use of loan participations with other commercial banks. Commercial and agricultural real estate loans commonly require loan-to-value limits of 80% or less. Depending upon the type of loan, past credit history, and current operating results,
13
we may require the borrower to pledge accounts receivable, inventory, property, or equipment. Government agency guarantee may be required. Personal guarantees and/or life insurance beneficiary assignments are generally required from the owners of closely held corporations, partnerships, and sole proprietorships. In addition, we may require annual financial statements, prepare cash flow analyses, and review credit reports.
We offer adjustable-rate mortgages, construction loans, and fixed rate residential real estate loans which have amortization periods up to a maximum of 30 years. We consider the anticipated direction of interest rates, balance sheet duration, the sensitivity of our balance sheet to changes in interest rates, our liquidity needs, and overall loan demand to determine whether or not to sell fixed rate loans to Freddie Mac.
Our lending policies generally limit the maximum loan-to-value ratio on residential real estate loans to 100% of the lower of the appraised value of the property or the purchase price. Private mortgage insurance is typically required on loans with loan-to-value ratios in excess of 80% unless the loan qualifies for government guarantees.
Underwriting criteria for originated residential real estate loans generally include:
•Evaluation of the borrower’s ability to make monthly payments.
•Evaluation of the value of the property securing the loan.
•Ensuring the payment of principal, interest, taxes, and hazard insurance generally does not exceed 28% of a borrower’s gross income.
•Ensuring all debt servicing does not exceed 40% of income.
•Verification of acceptable credit reports.
•Verification of employment, income, and financial information.
Appraisals are performed by independent appraisers and are reviewed for appropriateness. Generally, mortgage loan requests are reviewed by our mortgage loan committee or through a secondary market underwriting system; loans in excess of $1,000 require the approval of one or more of the following committees: Internal Loan Committee, the Executive Loan Committee, or the Board of Directors.
Consumer loans include secured and unsecured personal loans. Loans are amortized for a period of up to 15 years based on the age and value of the underlying collateral. The underwriting emphasis is on a borrower’s perceived intent and ability to pay rather than collateral value. No consumer loans are sold to the secondary market.
Nonaccrual and Past Due Loans
The accrual of interest on commercial and agricultural loans, as well as residential real estate loans, is discontinued at the time a loan is 90 days or more past due unless the credit is well-secured and in the process of short-term collection. Upon transferring a loan to nonaccrual status, we perform an evaluation to determine the net realizable value of the underlying collateral. This evaluation is used to help determine if a charge-off is necessary. Consumer loans are typically charged off no later than 180 days past due. Past due status is based on the contractual term of the loan. In all cases, a loan is placed in nonaccrual status at an earlier date if collection of principal or interest is considered doubtful.
When a loan is placed in nonaccrual status, all interest accrued in the current calendar year, but not collected, is reversed against interest income while interest accrued in prior calendar years, but not collected, is charged against the ACL. Loans may be returned to accrual status after six months of continuous performance and achievement of current payment status. Accrued interest receivable on loans was $5,858 and $6,384 at June 30, 2025 and December 31, 2024, respectively, which is included in other assets on the consolidated balance sheets.

We have certain lending policies and procedures in place designed to maximize loan income within an acceptable level of risk. The Board of Directors reviews and approves these policies and procedures on a regular basis. A reporting system supplements the review process by providing management and the Board of Directors with frequent reports related to loan production, loan quality, and concentration of credit, loan delinquencies, nonperforming loans and potential problem loans. We seek to diversify the loan portfolio as a means of managing risk associated with fluctuations in economic conditions.
Internally assigned credit risk ratings are reviewed, at a minimum, when loans are renewed or when management has knowledge of improvements or deterioration of the credit quality of individual credits. Descriptions of the internally assigned credit risk ratings for commercial and agricultural loans are as follows:
1. EXCELLENT – Substantially Risk Free
Credit has strong financial condition and solid earnings history, characterized by:
•High liquidity, strong cash flow, low leverage.
•Unquestioned ability to meet all obligations when due.
•Experienced management, with management succession in place.
•Secured by cash.
2. HIGH QUALITY – Limited Risk
Credit with sound financial condition and a positive trend in earnings supplemented by:
•Favorable liquidity and leverage ratios.
•Ability to meet all obligations when due.
•Management with successful track record.
•Steady and satisfactory earnings history.
•If loan is secured, collateral is of high quality and readily marketable.
•Access to alternative financing.
•Well defined primary and secondary source of repayment.
•If supported by guaranty, the financial strength and liquidity of the guarantor(s) are clearly evident.
3. HIGH SATISFACTORY – Reasonable Risk
Credit with satisfactory financial condition and further characterized by:
•Working capital adequate to support operations.
•Cash flow sufficient to pay debts as scheduled.
•Management experience and depth appear favorable.
•Loan performing according to terms.
•If loan is secured, collateral is acceptable, and loan is fully protected.
4. SATISFACTORY – Acceptable Risk
Credit with bankable risks, although some signs of weaknesses are shown:
•Would include most start-up businesses.
•Occasional instances of trade slowness or repayment delinquency – may have been 10-30 days slow within the past year.
•Management’s abilities are apparent yet unproven.
•Weakness in primary source of repayment with adequate secondary source of repayment.
•Loan structure generally in accordance with policy.
•If secured, loan collateral coverage is marginal.
21
To be classified as less than satisfactory, only one of the following criteria must be met.
5. SPECIAL MENTION – Criticized
Credit constitutes an undue and unwarranted credit risk but not to the point of justifying a classification of substandard. The credit risk may be relatively minor yet constitutes an unwarranted risk in light of the circumstances surrounding a specific loan:
•Downward trend in sales, profit levels, and margins.
•Impaired working capital position.
•Cash flow is strained in order to meet debt repayment.
•Loan delinquency (30-60 days) and overdrafts may occur.
•Shrinking equity cushion.
•Diminishing primary source of repayment and questionable secondary source.
•Management abilities are questionable.
•Weak industry conditions.
•Litigation pending against the borrower.
•Loan may need to be restructured to improve collateral position or reduce payments.
•Collateral or guaranty offers limited protection.
•Negative debt service coverage, however, the credit is well collateralized, and payments are current.
6. SUBSTANDARD – Classified
Credit is inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged. There is a distinct possibility we will implement collection procedures if the loan deficiencies are not corrected. Any commercial loan placed in nonaccrual status will be rated “7” or worse. In addition, the following characteristics may apply:
•Sustained losses have severely eroded the equity and cash flow.
•Deteriorating liquidity.
•Serious management problems or internal fraud.
•Original repayment terms liberalized.
•Likelihood of bankruptcy.
•Inability to access other funding sources.
•Reliance on secondary source of repayment.
•Litigation filed against borrower.
•Interest non-accrual may be warranted.
•Collateral provides little or no value.
•Requires excessive attention of the loan officer.
•Borrower is uncooperative with loan officer.
7. VULNERABLE – Classified
Credit is considered “Substandard” and warrants placing in nonaccrual status. Risk of loss is being evaluated and exit strategy options are under review. Other characteristics that may apply:
•Insufficient cash flow to service debt.
•Minimal or no payments being received.
•Limited options available to avoid the collection process.
•Transition status, expect action will take place to collect loan without immediate progress being made.

22
8. DOUBTFUL – Workout
Credit has all the weaknesses inherent in a “Substandard” loan with the added characteristic that collection and/or liquidation is pending. The possibility of a loss is extremely high, but its classification as a loss is deferred until liquidation procedures are completed, or reasonably estimable. Other characteristics that may apply:
•Normal operations are severely diminished or have ceased.
•Seriously impaired cash flow.
•Original repayment terms materially altered.
•Secondary source of repayment is inadequate.
•Survivability as a “going concern” is impossible.
•Collection process has begun.
•Bankruptcy petition has been filed.
•Judgments have been filed.
•Portion of the loan balance has been charged off.
9. LOSS – Charge-off
Credit is considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification is for charged-off loans but does not mean that the asset has absolutely no recovery or salvage value. These loans are further characterized by:
•Liquidation or reorganization under bankruptcy, with poor prospects of collection.
•Fraudulently overstated assets and/or earnings.
•Collateral has marginal or no value.
•Debtor cannot be located.
•Over 120 days delinquent.

Loan Modifications
A loan modification includes terms outside of normal lending practices to a borrower experiencing financial difficulty.
Typical modifications granted include, but are not limited to:
•Agreeing to interest rates below prevailing market rates for debt with similar risk characteristics.
•Extending the maturity date or amortization period beyond typical lending guidelines for loans with similar risk characteristics.
•Agreeing to an interest-only payment structure, delaying principal payments, or delaying payments.
•Forgiving principal.
To determine if a borrower is experiencing financial difficulty, factors we consider include:
•The borrower is currently in default on any debt.
•The borrower would likely default on any debt if the concession is not granted.
•The borrower’s cash flow is insufficient to service all debt if the concession is not granted.
•The borrower has declared, or is in the process of declaring, bankruptcy.
•The borrower is unlikely to continue as a going concern (if the entity is a business).

ACL - Loans
The credit quality of our loan portfolio is continuously monitored and is reflected within the ACL for loans. The ACL is an estimate of expected losses inherent within our loan portfolio. The ACL is adjusted by a credit loss expense, which is reported in earnings, and reduced by the charge-off of loan amounts, net of recoveries.
The ACL is evaluated on a regular basis for appropriateness. Our periodic review of the collectability of a loan considers historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available.
The primary factors behind the determination of the level of the ACL are specific allocations for loans individually evaluated, historical loss percentages, delinquency status, and other credit trends and risk characteristics, including current conditions and reasonable and supportable forecasts about the future. Determining the appropriateness of the allowance is complex and requires judgment by management about the effect of matters that are inherently uncertain. In future periods evaluations of the overall loan portfolio, in light of the factors and forecasts then prevailing, may result in significant changes in the allowance and credit loss expense in those future periods.
The methodology for estimating the amount of expected credit losses reported in the ACL has two basic components: a component of individual loans that do not share risk characteristics with other loans; and a pooled component for estimated expected credit losses for pools of loans that share similar risk characteristics.
For a loan that does not share risk characteristics with other loans, an individual analysis is performed to measure an allowance. Loans in nonaccrual status are individually evaluated for specific allocation of the allowance using the fair value of collateral, less costs to sell if foreclosure is probable, or the discounted cash flow method. We do not recognize interest income on loans
29
in nonaccrual status. For loans not classified as nonaccrual, interest income is recognized daily, as earned, according to the terms of the loan agreement and the principal amount outstanding.
In determining the allowance for credit losses, we derive an estimated credit loss assumption from a model that categorizes loan pools based on loan type and credit risk ratings or delinquency bucket. This model calculates an expected loss percentage for each loan class by considering the probability of default, based on the migration of loans from performing to loss by credit risk ratings or delinquency buckets using life-of-loan analysis, and the historical severity of loss, based on the aggregate net lifetime losses incurred per loan class.
The default and severity factors used to calculate the allowance for credit losses for loans that share similar risk characteristics with other loans are adjusted for differences between the historical period used to calculate historical default and loss severity rates and expected conditions over the remaining lives of the loans in the portfolio. These qualitative factors are used to adjust the historical probabilities of default and severity of loss so that they reflect management's expectation of future conditions based on a reasonable and supportable forecast. To the extent the lives of the loans in the portfolio extend beyond the period for which a reasonable and supportable forecast can be made, the model reverts back to the historical rates of default and severity of loss. Qualitative factors include:
•Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, recovery practices not considered elsewhere in estimating credit losses;
•Changes in the experience, ability, and depth of lending management and other relevant staff;
•Changes in interest rates;
•Changes in international, national, regional, and local economic factors;
•Changes in the nature and volume of the portfolio and in the terms of loans;
•Changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans;
•Lack of current financial information;
•Competition, legal, and regulatory; and
•Changes in the value of underlying collateral.

We have designated loans classified as collateral dependent for which we apply the practical expedient to measure the ACL based on the fair value of the collateral less cost to sell when the repayment is expected to be provided substantially by the sale or operation of the collateral and the borrower is experiencing financial difficulty. The fair value of the collateral is based on appraisals, which may be adjusted due to their age, and the type, location, and condition of the property or area or general market conditions to reflect the expected change in value between the effective date of the appraisal and the measurement date. Appraisals are updated every one to two years depending on the type of loan and the total exposure of the borrower. Loans evaluated for expected credit losses on an individual basis as of June 30, 2025 include $1,087 in collateral dependent loans secured by commercial real estate and residential real estate of $533 and $554, respectively.

Note 6 – Capital Ratios and Shareholders' Equity
As of June 30, 2025 and December 31, 2024, the most recent notifications from the FRB and the FDIC categorized us as “well capitalized” under the FDIC's regulatory framework for prompt corrective action and the Basel III capital guidelines. To be categorized as “well capitalized,” an institution must maintain minimum total risk-based, Tier 1 risk-based, common equity Tier 1, and Tier 1 leverage ratios as set forth in the following tables. The minimum requirements presented below include the minimum required capital levels based on the Basel III capital guidelines. Capital requirements to be considered “well capitalized” are based upon the FDIC's prompt corrective action regulations, as amended to reflect the changes under the Basel III capital guidelines. There were no conditions or events since the notifications that we believe have changed our categories. The following tables set forth these requirements and our ratios, both on a bank-only and on a consolidated basis, as of:

Note 7 – Fair Value
Under fair value measurement and disclosure authoritative guidance, we group assets and liabilities measured at fair value into three levels, based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine fair value, based on the prioritization of inputs in the valuation techniques. These levels are:
Level 1:Valuation is based upon quoted prices for identical instruments traded in active markets.
Level 2:Valuation is based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market.
Level 3:Valuation is generated from model-based techniques that use at least one significant assumption not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in pricing the asset or liability.
The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. Valuation techniques maximize the use of observable inputs and minimize the use of unobservable inputs. Transfers between measurement levels are recognized at the end of reporting periods.
Fair value measurement requires the use of an exit price notion which may differ from entrance pricing. Generally, we believe our assets and liabilities classified as Level 1 or Level 2 approximate an exit price notion.
Following is a description of the valuation methodologies, key inputs, and an indication of the level of the fair value hierarchy in which the assets or liabilities are classified.
AFS securities: AFS securities are recorded at fair value on a recurring basis. Level 1 fair value measurement is based upon quoted prices for identical instruments. Level 2 fair value measurement is based upon quoted prices for similar instruments. If quoted prices are not available, fair values are measured using independent pricing models or other model-based valuation techniques such as the present value of future cash flows, adjusted for the security’s credit rating, prepayment assumptions and other factors such as credit loss and liquidity assumptions. The values for Level 1 and Level 2 investment securities are generally obtained from an independent third party. On a quarterly basis, we compare the values provided to alternative pricing sources.
Loans: We do not record loans at fair value on a recurring basis. However, some loans are individually evaluated for ACL purposes, and a specific ACL may be established. To measure reserve, the fair value of the loan is estimated using the fair value of the collateral, less costs to sell if foreclosure is probable, or the present value of expected future cash flows discounted at the loan’s effective interest rate. Loans not requiring an allowance represent loans for which the fair value of the expected repayments or collateral exceed the recorded investments in such loans.
We review the net realizable values of the underlying collateral for collateral dependent loans on at least a quarterly basis for all loan types. To determine the collateral value, we utilize independent appraisals, broker price opinions, or internal evaluations. We review these valuations to determine whether an additional discount should be applied given the age of market information that may have been considered as well as other factors such as costs to sell an asset if it is determined that the collateral will be liquidated in connection with the ultimate settlement of the loan. We use these valuations to determine if any specific reserves or charge-offs are necessary. We may obtain new valuations in certain circumstances, including when there has been significant deterioration in the condition of the collateral, if the foreclosure process has begun, or if the existing valuation is deemed to be outdated.

Collateral discount rates may have ranges to accommodate differences in the age of the independent appraisal, broker price opinion, or internal evaluation.
OMSR: OMSR (which are included in other assets) are subject to impairment testing. To test for impairment, we utilize a discounted cash flow analysis using interest rates and prepayment speed assumptions currently quoted for comparable instruments and discount rates. If the valuation model reflects a value less than the carrying value, OMSR are adjusted to fair value through a valuation allowance as determined by the model. As such, we classify OMSR subject to nonrecurring fair value adjustments as Level 3.

The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Although we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement.
Estimated Fair Values of Financial Instruments Not Recorded at Fair Value in their Entirety on a Recurring Basis
Disclosure of the estimated fair values of financial instruments, which differ from carrying values, often requires the use of estimates. In cases where quoted market values in an active market are not available, we use present value techniques and other valuation methods to estimate the fair values of our financial instruments. These valuation methods require considerable judgment and the resulting estimates of fair value can be significantly affected by the assumptions made and methods used.

This analysis should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the SEC on March 12, 2025 (the “2024 Annual Report on Form 10-K”) and with the unaudited interim condensed consolidated financial statements and notes, beginning on page 4 of this Form 10-Q. Unless we state otherwise or the context otherwise requires, references in this Form 10-Q to “we,” “our,” “us,” and “the Corporation” refer to Isabella Bank Corporation, a Michigan corporation and registered financial holding company, our wholly-owned banking subsidiary, Isabella Bank, and our other consolidated subsidiaries. References to the “Bank” refer to Isabella Bank.

Cautionary Notice Regarding Forward-Looking Statements
This Form 10-Q contains statements that we believe are “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). These forward-looking statements reflect our current views with respect to, among other things, future events and our financial performance.

Non-GAAP Financial Measures
Our accounting and reporting policies conform to GAAP and the prevailing practices in the financial services industry. However, we also evaluate our performance by reference to certain additional financial measures discussed in this Quarterly Report on Form 10-Q that we identify as being “non-GAAP financial measures.” In accordance with SEC rules, we classify a financial measure as being a non-GAAP financial measure if that financial measure excludes or includes amounts, or is subject to adjustments that have the effect of excluding or including amounts, as the case may be, in the most directly comparable measure calculated and presented in accordance with GAAP as in effect from time to time in the United States in our statements of income, balance sheets or statements of cash flows. Non-GAAP financial measures do not include operating and other statistical measures or ratios, or statistical measures calculated using exclusively either financial measures calculated in accordance with GAAP, operating measures or other measures that are not non-GAAP financial measures or both.
The non-GAAP financial measures that we discuss in this Quarterly Report on Form 10-Q should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Moreover, the manner in which we calculate the non-GAAP financial measures that we discuss in this report may differ from that of other companies reporting measures with similar names.

Executive Summary
Comparison of Operating Results for the three and six months ended June 30, 2025, and 2024, unless otherwise noted
Net income in the second quarter of 2025 was $5,031, or $0.68 per diluted share, compared with $3,481, or $0.46 per diluted share, in the same quarter 2024. The non-GAAP measure of adjusted net income in the second quarter 2025 totaled $4,096, or $0.55 per diluted share, compared to $3,476 or $0.46 per diluted share, in the same quarter of 2024.
Net income for the year-to-date period of 2025 was $8,980, or $1.21 per diluted share, compared with $6,612, or $0.88 per diluted share, in the same period of 2024. Adjusted net income was $8,350, or $1.13 per diluted share, compared with $6,553, or $0.87 per diluted share, for the respective periods.
Net interest income was $15,129 in the second quarter of 2025 and $13,550 in the same quarter of 2024, representing 3.14% and 2.82% of earning assets, or NIM on an FTE basis, respectively. The book yield from securities was 2.38% and 2.17% during the second quarters of 2025 and 2024, respectively. Our yield on loans expanded to 5.71% in the second quarter 2025, up from 5.50% in the same quarter of 2024. The expansion in loan yields was a result of higher rates on new loans and variable rate commercial loans that continue to reprice. At the end of the second quarter 2025, approximately 38% of commercial loans were fixed at rates that are lower than current market. Most of those fixed rate loans will contractually reprice to variable rates over the next four years. Our cost of interest-bearing liabilities in the second quarter 2025 decreased to 2.24% from 2.38% in the second quarter 2024 due to reductions to rates in the money market and certificate of deposit products. NIM is expected to continue to expand as loans reprice and the cost of interest-bearing liabilities stabilizes.
For the first six months of 2025, net interest income was $29,654 compared with $26,792 in the same period of 2024. The comparison of NIM and yield on interest earning assets for the six months ending June 30, 2025 were 3.10% and 4.78%, respectively, compared to 2.81% and 4.54%, respectively, for the same period in 2024. The yield on loans expanded to 5.72%, from 5.45%, and our cost of interest bearing liabilities decreased to 2.25% from 2.33% for the first six months of 2025 and 2024, respectively. The explanations for the improvement in NIM are consistent with those provided in the year-over-year three month comparison above.
The provision for credit losses was a credit of $1,099 in the second quarter of 2025, which reflects net recoveries totaling $1,432, partially offset by a $242 increase in the ACL on loans and an increase in the reserve for unfunded commitments. Recoveries totaled $1,822, of which $1,556 were related to overdrawn deposit accounts from a single customer charged off during the third quarter of 2024. The provision for loan losses in the same period of 2024 was $170 due to growth in core loans, which excludes advances to mortgage brokers (non-GAAP), and unfunded commitments.
For the first half of 2025, provision for credit losses was a credit of $1,206 compared to a provision of $562 in the same period of 2024. The drivers of the credit and provision for the six month comparison are consistent with those provided in the three month comparison above. Credit quality remains strong with low levels of past due and nonaccrual loans and net charge offs. The Corporation continues to closely monitor credit quality in light of the continued economic uncertainty caused by, among other factors, the interest rate environment, employment data in recent periods, continued uncertainty regarding U.S. trade and tariff policy and the lingering inflationary pressures, and the risk of the resurgence of elevated levels of inflation, in the United States and our market areas. Accordingly, additional provisions for credit losses may be necessary in future periods.
Noninterest income for the three months ended June 30, 2025 and 2024 was $3,686 and $3,608, respectively. Service charges and fees increased $48 as a result of profitability initiatives designed to increase fee income. Wealth management fees grew $36 due to growth in assets under management as compared to the second quarter of 2024. AUM totaled $678,959, $656,617, and $647,850 as of June 30, 2025, March 31, 2025, and June 30, 2024, respectively. Earnings on BOLI policies increased $47 over the prior year quarter due to new investments in a separate account BOLI, which was offset in part by a one-time expense of $120 due to restructuring charges. For the first six months of 2025, noninterest income was $7,214, compared to $7,076 in the same period of 2024. Service charges and fees, wealth management fees, and earnings on BOLI policies increased $89, $76, and $176, respectively. The reasons for the increase in noninterest income for the six month comparison are the same as the three month comparison.
Noninterest expenses for the three-month period ended June 30, 2025 increased $850 in comparison to the same period in 2024. Compensation and benefit expenses increased $526 reflecting annual merit increases in 2025, incentives, and higher medical insurance claims compared to the second quarter of 2024. Other professional services increased $336 primarily due to $173 in fees related to profitability initiative costs and $47 in legal fees related to our Nasdaq uplisting. For the first six months of 2025, noninterest expenses were $27,044, compared to $25,571 in the same period of 2024. Compensation and benefits increased $894 for the same reasons as the three month comparison. Other professional service fees increased $534 principally due to the second quarter profitability initiative costs and $168 in legal fees related to our Nasdaq uplisting.
43
Income tax expense for the three months ended June 30, 2025 and 2024 was $1,138 and $612 and the ETR was 18% and 15%, respectively. The increase in the ETR was primarily due to a higher annual forecast of pretax income. Income tax expense for the first six months of 2025 was $2,050, compared to $1,123 in the same period of 2024 and the ETR was 19% and 15%, respectively. The ETR in the first six months of 2025 included a one-time expense totaling $166 due to the taxes owed from the lifetime earnings on BOLI policies that were surrendered during the first quarter. Excluding the one-time charge, the ETR was 17%, which is higher than the prior year due to a higher annual forecast of pretax income.
Financial Condition (June 30, 2025 to December 31, 2024 comparison)
Total assets increased $69,927 to $2,156,168 as of June 30, 2025, primarily due to an increase of $72,596 in interest bearing cash, $11,531 increase in AFS securities, and a $10,892 increase in BOLI policies, offset by a $26,058 decrease in gross loans.
Our AFS securities portfolio totaled $500,560 at June 30, 2025, increasing $11,531 at the end of second quarter 2025. The increase was driven by $51,000 in purchases with a weighted-average yield of 4.63%. Amortization and maturities of $47,819 offset the increase from purchases. Net unrealized losses at June 30, 2025 totaled $17,594, or 3.40%, of the portfolio and improved during the quarter due to the treasury portfolio rapidly approaching maturity and a decrease in market yields. The par value and corresponding book yields that are estimated to mature or payoff by year include: $28,200 in principal with a weighted-average book yield of 2.36% over the remainder of 2025; $217,400 at 1.17% in 2026; and $63,000 at 1.87% in 2027. Some of these securities amortize so the actual principal paydown may differ from these estimates.
Gross loans decreased $26,058 to $1,397,513 as of June 30, 2025 totaled $1,397,513. While core loans (non-GAAP) grew $34,017, advances to mortgage brokers decreased $60,075 due to lower participation demand from our counterparty. However, the decline in advances to mortgage brokers has provided liquidity to refocus on loans that can be recorded on our balance sheet for longer terms and help to mitigate interest rate risk.
Core loans (non-GAAP) grew $34,017, led by growth in the commercial and industrial and commercial real estate portfolios of $7,096 and $22,665, respectively. Commercial loan growth during the year was in the real estate, construction, and hospitality industries. While our commercial pipeline is strong at the beginning of the third quarter, our ability to grow the loan portfolio is subject to uncertainties around timing and funding, customer demand, and overall economic conditions. Residential mortgages increased $17,796 since year-end 2024 with $11,320 of growth in the second quarter as construction drawdowns and seasonal patterns occurred. Most residential originations were adjustable rate products, which are put on the balance sheet rather than sold in the secondary market. The consumer loan portfolio continues to roll off amid decreasing demand, competition and our adherence to credit quality standards.
The ACL was $12,977 at June 30, 2025, an increase of $82 from $12,895 at December 31, 2024. The increase is due to core loan growth (non-GAAP), offset by improvement in historical loss experience driven by the recovery of previously charged-off loans during the year. Nonaccrual loans were $1,164 as of June 30, 2025 compared to $282 at December 31, 2024. Past due and accruing accounts between 30 to 89 days as a percentage of total loans was 0.08% at June 30, 2025, compared to 0.40% at year-end 2024. Overall, credit quality remains strong, and there are no negative trends.
BOLI assets were $45,774 at June 30, 2025, an increase of $10,892 from December 31, 2024. The growth was mostly driven by a $10,583 investment of new policies in a separate account product at the beginning of January. In the first half of 2025, we also surrendered and/or exchanged $13,721 of existing general account policies and redeployed the funds into a separate account BOLI. As part of BOLI restructuring, another $914 of general account policies will be exchanged for separate account BOLI, which is expected to be completed by the end of the third quarter of 2025. The separate account BOLI currently yields 5.4%, compared to a weighted-average yield of 2.9% from existing general account policies.
Total deposits increased $102,316 from December 31, 2024, to $1,849,376 at June 30, 2025. The growth was driven by demand and money market deposits. The $77,104 increase in demand deposits was primarily driven by one customer with large deposits during the second quarter that are expected to be withdrawn by the customer by the end of the year. Consumer demand for retail certificates of deposit accounts continues based on the rate environment, resulting in a $8,341 increase in the balance during the first six months of 2025.
Total equity was $220,500, or $29.95 per share, at June 30, 2025 compared to $210,276, or $28.32 per share, at year-end 2024. Our tangible book value per share (non-GAAP) was $23.39 as of June 30, 2025, compared to $21.82 on December 31, 2024. Net unrealized losses on AFS securities reduced tangible book value per share by $1.90 and $2.82 for the respective periods. Share repurchases totaled 103,406 during the first six months of 2025 for a value of $2,650 at an average price of $25.63.
We continue to have robust liquidity levels and capital. As of June 30, 2025, we had $925,528 of unencumbered sources of liquidity and strong capital ratios; the Tier 1 Leverage Ratio was 9.04%, Tier 1 risk-based capital was 12.46%, and Total risk-based capital was 15.34%.

Recent Events
On July 4, 2025, the One Big Beautiful Bill Act (the “OBBBA”) was signed into law by President Trump, which includes a broad range of tax reform provisions affecting businesses, including extending and modifying certain key provisions from the Tax Cuts and Jobs Act of 2017 and expanding certain incentives from the Inflation Reduction Act of 2022 while accelerating the phase-out of others. The Corporation continues to evaluate the OBBBA but does not anticipate that the OBBBA will have a material impact on the Corporation’s Consolidated Financial Statements. As the legislation was signed into law after the close of the second quarter of 2025, the impacts are not included in the Corporation’s operating results for the three and six months ended June 30, 2025.

Commercial real estate loans are subject to a varying degree of risk from changes in interest rates and economic conditions. To control these risks, we maintain strict underwriting standards, lending limits to a single borrower, loan to collateral value limits, and a defined market area. We also monitor and limit loan concentrations to specific industries. Our practices also include appropriate loan reviews, and monitoring of past due levels, concentrations, industry trends, and other qualitative factors.

Capital
Capital consists solely of common stock, retained earnings, and accumulated other comprehensive income (loss). We are authorized to raise capital through dividend reinvestment, employee and director stock purchases, and shareholder stock purchases. Pursuant to these authorizations, we issued 28,830 shares or $759 of common stock during the first six months of 2025, as compared to 43,980 shares or $840 of common stock during the same period in 2024. We offer the Directors Plan in which participants purchase stock units through deferred fees, in lieu of cash payments. Pursuant to this plan, we increased shareholders’ equity by $201 and $279 during the six-month periods ended June 30, 2025 and 2024, respectively. We also grant restricted stock awards pursuant to the RSP. Pursuant to this plan, we increased shareholders’ equity by $21 during the first six months of 2025, as compared to $45 during the same period in 2024.
We have publicly announced a common stock repurchase program. Pursuant to this repurchase program, we repurchased 103,406 shares or $2,650 of common stock during the first six months of 2025 and 72,093 shares or $1,402 of common stock during the first six months of 2024. As of June 30, 2025, we were authorized to repurchase up to an additional 514,823 shares of common stock under the repurchae program.
The FRB has established minimum risk-based capital guidelines. Pursuant to these guidelines, a framework has been established that assigns risk weights to each category of on and off-balance-sheet items to arrive at risk adjusted total assets. Regulatory capital is divided by the risk adjusted assets with the resulting ratio compared to the minimum standard to determine whether a corporation has adequate capital. At June 30, 2025, we and the Bank were “well capitalized” under the regulatory framework for prompt corrective action. Management believes that no conditions or events have occurred since June 30, 2025 that would materially adversely change such capital classifications. From time to time, we may need to raise additional capital to support our and the Bank’s further growth and to maintain our “well capitalized” status.
The following table sets forth our consolidated capital ratios as of:

Community Bank Leverage Ratio
On September 17, 2019, the federal banking agencies jointly finalized a rule to be effective January 1, 2020 and intended to simplify the regulatory capital requirements described above for qualifying community banking organizations that opt into the Community Bank Leverage Ratio (“CBLR”) framework, as required by Section 201 of the EGRRCPA. The final rule became effective on January 1, 2020, and the CBLR framework became available for banks to use beginning with their March 31, 2020 Call Reports. Under the final rule, if a qualifying community banking organization opts into the CBLR framework and meets all requirements under the framework, it will be considered to have met the well-capitalized ratio requirements under the “prompt corrective action” regulations described above and will not be required to report or calculate risk-based capital. In order to qualify for the CBLR framework, a community banking organization must have a tier 1 leverage ratio of greater than 9%, less than $10 billion in total consolidated assets, and limited amounts of off-balance sheet exposures and trading assets and liabilities. Although the Corporation and the Bank are qualifying community banking organizations, the Corporation and the Bank have elected not to opt in to the CBLR framework at this time and will continue to follow the Basel III capital requirements as described in “Note 6 – Capital Ratios and Shareholders' Equity” of our interim condensed consolidated financial statements included with this Form 10-Q.
Liquidity
Liquidity is monitored regularly by our ALCO, which consists of members of senior management. The committee reviews projected cash flows, key ratios, and liquidity available from both primary and secondary sources.
Our primary sources of liquidity are retail deposits, cash and cash equivalents, and unencumbered AFS securities. Cash, cash equivalents and unencumbered AFS securities totaled $453,330, or 21.02% of assets, as of June 30, 2025, compared to $330,876, or 15.86%, as of December 31, 2024. The increase in the amount and percentage of primary liquidity is a direct result of an increase in cash, driven by deposit growth. Liquidity is important for financial institutions because of their need to meet loan funding commitments, depositor withdrawal requests, and various other commitments including expansion of operations, investment opportunities, and payment of cash dividends. Based on these same factors, daily liquidity could vary significantly.
51
Our secondary sources include the ability to borrow from the FHLB, from the FRB, and through various correspondent banks in the form of federal funds purchased and lines of credit. These funding methods typically carry a higher interest rate than traditional market deposit accounts. Some borrowed funds, including FHLB advances, FRB Discount Window advances, and repurchase agreements, require us to pledge assets, typically in the form of AFS securities or loans, as collateral. As of June 30, 2025, we had available lines of credit of $376,974.
We monitor our daily liquidity position to meet our cash flow needs. We also forecast anticipated funding needs for changes in interest rates and economic conditions, the scheduled maturity and interest rate sensitivity of the investment and loan portfolios and deposits, and regulatory capital requirements. Our liquidity stress testing is designed with consideration of these and other factors that could pose undue risk to liquidity.
Our liquidity position remained strong at June 30, 2025, which is illustrated in the following table:

Fair Value
We utilize fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. AFS securities, cash flow hedge derivative instruments and certain liabilities are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record at fair value other assets on a nonrecurring basis, such as mortgage loans AFS, collateral dependent loans, goodwill, foreclosed assets, OMSR, and certain other assets and liabilities. These nonrecurring fair value adjustments typically involve the application of lower of cost or market accounting or write downs of individual assets.
For further information regarding fair value measurements see “Note 7 – Fair Value” of our interim condensed consolidated financial statements included with this Form 10-Q.
Interest Rate Sensitivity and Market Risk
As a financial institution, our primary market risks are interest rate risk and liquidity risk. IRR is the exposure of our net interest income to changes in interest rates. IRR results from the difference in the maturity or repricing frequency of a financial institution's interest earning assets and its interest-bearing liabilities. Managing IRR is the fundamental method by which financial institutions earn income and create shareholder value. Excessive exposure to IRR could pose a significant risk to our earnings and capital.
The FRB has adopted a policy requiring banks to effectively manage the various risks that can have a material impact on safety and soundness. The risks include credit, interest rate, liquidity, operational, and reputational. We have policies, procedures, and internal controls for measuring and managing these risks. Specifically, our ALCO policy and procedures include defining acceptable types and terms of investments and funding sources, liquidity requirements, limits on investments in long-term assets, limiting the mismatch in repricing opportunities of assets and liabilities, and the frequency of measuring and reporting to our Board of Directors.
52
The primary technique to measure IRR is simulation analysis. Simulation analysis forecasts the effects on the balance sheet structure and net interest income under a variety of scenarios that incorporate changes in interest rates, the shape of yield curves, interest rate relationships, loan prepayments, and funding sources. These forecasts are compared against net interest income projected in a stable interest rate environment. While many assets and liabilities reprice either at maturity or in accordance with their contractual terms, several balance sheet components demonstrate characteristics that require an evaluation to more accurately reflect their repricing behavior. Key assumptions in the simulation analysis include prepayments on loans, probable calls of investment securities, changes in market conditions, loan volumes and loan pricing, deposit sensitivity, and customer preferences. These assumptions are inherently uncertain as they are subject to fluctuation and revision in a dynamic rate environment. As a result, the simulation analysis cannot precisely forecast the impact of rising and falling interest rates on net interest income. Actual results will differ from simulated results due to many other factors, including changes in balance sheet components, interest rate changes, changes in market conditions, and management strategies. We regularly monitor our projected net interest income sensitivity to ensure that it remains within established limits.
The following tables summarize our interest rate sensitivity for 12 and 24 months as of June 30, 2025 and December 31, 2024. The results displayed in the tables reflect the modeling of immediate shifts in the yield curve and a flat balance sheet and do not reflect actual or expected changes.

Gap analysis, the secondary method to measure IRR, measures the cash flows and/or the earliest repricing of our interest-bearing assets and liabilities. This analysis is useful for measuring trends in the repricing characteristics of the balance sheet. Significant assumptions are required in this process because of the embedded repricing options contained in assets and liabilities. Residential real estate and consumer loans allow the borrower to repay the balance prior to maturity without penalty, while commercial and agricultural loans may have prepayment penalties. The amount of prepayments is dependent upon many factors, including the interest rate of a given loan in comparison to the current offering rates, the level of home sales, and the overall availability of credit in the marketplace. Generally, a decrease in interest rates will result in an increase in cash flows from these assets. Savings and demand accounts may generally be withdrawn on request without prior notice. The timing of cash flows from these deposits is estimated based on historical experience. Certificates of deposit have penalties that discourage early withdrawals.
We do not believe there has been a material change in the nature or categories of our primary market risk exposure, or the particular markets that present the primary risk of loss. We do not know of or expect there to be any material change in the general nature of our primary market risk exposure in the near term, and we do not expect to make material changes to our market risk methods in the near term. We may change those methods in the future to adapt to changes in circumstances or to implement new techniques.
Gap analysis is also utilized as a method to measure interest rate sensitivity. Interest rate sensitivity is determined by the amount of earning assets and interest-bearing liabilities repricing within a specific time period, and their relative sensitivity to a change in interest rates. We strive to achieve reasonable stability in the net interest margin through periods of changing interest rates.
Contractual Obligations and Loan Commitments
We have various financial obligations, including contractual obligations and commitments related to deposits and borrowings, which may require future cash payments. We also have loan related commitments that may impact liquidity. The commitments include unused lines of credit, commercial and standby letters of credit, and commitments to grant loans. These commitments to grant loans include residential mortgage loans with the majority committed to be sold to the secondary market. Many of these commitments historically have expired without being drawn upon and do not necessarily represent our future cash requirements.
53
We are party to credit related financial instruments with off-balance-sheet risk. These financial instruments are entered into in the normal course of business to meet the financing needs of our customers. These financial instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated balance sheets. The contractual or notional amounts of these instruments reflect the extent of involvement we have in a particular class of financial instrument.
Our exposure to credit-related loss in the event of nonperformance by the counterparties to the financial instruments for commitments to extend credit and standby letters of credit could be up to the contractual notional amount of those instruments. We use the same credit policies when analyzing the creditworthiness of counterparties as we do for extending loans to customers. No significant losses are anticipated as a result of these commitments.
Impact of Inflation
Our consolidated financial statements and related notes included elsewhere in this Form 10-Q have been prepared in accordance with GAAP. GAAP requires the measurement of financial position and operating results in terms of historical dollars, without considering changes in the relative value of money over time due to inflation or recession.
The Corporation’s asset and liability structure is substantially different from that of an industrial company in that virtually all assets and liabilities of the Corporation are monetary in nature. Management believes the impact of inflation on financial results depends upon the Corporation’s ability to react to changes in interest rates and by such reaction, reduce the inflationary impact on performance. Interest rates do not necessarily move in the same direction, or at the same magnitude, as the prices of other goods and services. However, other operating expenses do reflect general levels of inflation. Management seeks to manage the relationship between interest rate-sensitive assets and liabilities in order to protect against wide net interest income fluctuations, including those resulting from inflation.
Various information shown elsewhere in this Form 10-Q will assist in the understanding of how well the Corporation is positioned to react to changing interest rates and inflationary trends. In particular, additional information related to the Corporation’s interest rate-sensitive assets and liabilities is contained in this Item 2, “Management's Discussion and Analysis of Financial Condition and Results of Operations” of this Form 10-Q under the heading “Interest Rate Sensitivity and Market Risk.”
