Management determines the appropriate classification of debt securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Investment securities classified as available for sale are those securities that the Bank intends to hold for an indefinite period of time but not Investment securities classified as held to maturity are those securities the Bank has both the intent and ability to hold to maturity regardless of changes in market conditions, liquidity needs, or changes in general economic conditions. These securities are carried at cost, adjusted for the amortization of premium and accretion of discount, and computed by a method that approximates the interest method over the terms of the securities. As of June 30, 2023, not Equity securities are measured at fair value with changes in fair value recognized in net income. Allowance for Credit Losses Available for Sale Securities The Bank measures expected credit losses on available-for-sale debt securities when the Bank intends to sell, or when it is more likely than not not not The allowance for credit losses on available-for-sale debt securities is included within investment securities available for sale on the consolidated balance sheet. Changes in the allowance for credit losses are recorded within provision for credit losses on the consolidated statement of income. Losses are charged against the allowance when the Bank believes the collectability of an available-for-sale security is in jeopardy or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on available-for-sale debt securities totaled $1.7 million on June 30, 2023, 90 Credit Losses on Investment Securities Prior to adopting ASU 2016 13 The Bank adopted ASU No. 2016 13 January 1, 2023. December 31, 2022, December 31, 2022, 10 December 31, 2022 Investment securities are classified at the time of purchase, based on management’s intention and ability, as securities held to maturity or securities available for sale. Debt securities acquired with the intent and ability to hold to maturity are stated at cost, adjusted for amortization of premium and accretion of discount, computed using a level yield method, and recognized as interest income adjustments. Certain other debt securities have been classified as available for sale to serve principally as a source of liquidity. Unrealized holding gains and losses for available-for-sale securities are reported as a separate component of stockholders’ equity, net of tax until realized. Realized security gains and losses are computed using the specific identification method. Interest and dividends on investment securities are recognized as income when earned. For 2022, Securities are evaluated quarterly and more frequently when economic or market conditions warrant such an evaluation to determine whether a decline in their value is other-than-temporary. For debt securities, management considers whether the present value of cash flows expected to be collected is less than the security’s amortized cost basis (the difference defined as the credit loss), the magnitude and duration of the decline, the reasons underlying the decline and the Bank’s intent to sell the security or whether it is more likely than not not not not Loans Receivable Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are stated at their outstanding unpaid principal balances, net of an allowance for loan losses, and any deferred fees or costs. Accrued interest receivable totaled $4.7 million on June 30, 2023, The loans receivable portfolio is segmented into commercial and consumer loans. Commercial loans consist of the following classes: commercial construction, commercial and industrial loans, and commercial real estate loans. Consumer loans consist of the following classes: residential real estate loans, home equity loans, and consumer loans. For all classes of loans receivable, the accrual of interest is discontinued when the contractual payment of principal or interest has become 90 may no Purchased Credit Deteriorated (PCD) Loans The Bank has purchased loans, some of which have experienced more than insignificant credit deterioration since origination. The Bank reviews many factors to make the determination, including reviewing whether the loan is performing, delinquency status, and changes in risk rating to determine if the loan exhibits more than insignificant credit deterioration. PCD loans are recorded at the amount paid. An allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The sum of the loan’s purchase price and allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through credit loss expense. Allowance for Credit Losses (ACL) Loans The allowance for credit losses is a valuation reserve established and maintained by charges against income and is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. Loans, or portions thereof, are charged off against the ACL when they are deemed uncollectible. Expected recoveries do not The ACL is an estimate of expected credit losses, measured over the contractual life of a loan, that considers our historical loss experience, current conditions and forecasts of future economic conditions. Determination of an appropriate ACL is inherently subjective and may Management uses a discounted cash flow (DCF) model to calculate the present value of the expected cash flows for pools of loans and leases that share similar risk characteristics and compares the results of this calculation to the amortized cost basis to determine its allowance for credit loss balance. The contractual term used in projecting the cash flows of a loan is based on the maturity date of a loan, and is adjusted for prepayment or curtailment assumptions which may The key inputs to the DCF model are ( 1 2 3 4 5 6 7 Probability of Default (PD) In order to incorporate economic factors into forecasting within the DCF model, management elected to use the Loss Driver method to generate the PD rate inputs. The Loss Driver method analyzes how one Loss Given Default (LGD) Management elected to use the Frye Jacobs parameter for determining the LGD input, which is an estimation technique that derives an LGD input from segment-specific risk curves that correlates LGD with PD. Prepayment and Curtailment rates Prepayment Rates: Loan-level transaction data is used to calculate a semi-annual prepayment rate. Those semi-annual rates are annualized and the average of the annualized rates is used in the DCF calculation for fixed payment or term loans. Rates are calculated for each pool. Curtailment Rates: Loan-level transaction data is used to calculate annual curtailment rates using any available historical loan-level data. The average of the historical rates is used in the DCF model for interest-only payment or line-of-credit type loans. Rates are calculated for each pool. Reasonable and Supportable Forecasts The forecast data used in the DCF model is obtained via a subscription to a widely recognized and relied-upon company that publishes various forecast scenarios. Management evaluates the various scenarios to determine a reasonable and supportable scenario. Forecast Reversion Period Management uses forecasts to predict how economic factors will perform and has determined to use a four eight Expected Recoveries on Charged-off Loans Management performs an analysis to estimate recoveries that could be reasonably expected based on historical experience in order to account for expected recoveries on loans that have already been fully charged off and are not Discount Rate The effective interest rate of the underlying loans and leases of the Corporation serves as the discount rate applied to the expected periodic cash flows. Management adjusts the effective interest rate used to discount expected cash flows to incorporate expected prepayments. Individual Evaluation Management evaluates individual instruments for expected credit losses when those instruments do not not Management considers a financial asset as collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral, based on management's assessment as of the reporting date. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. The Company’s loan portfolio is segmented to a level that allows management to monitor risk and performance. The portfolio is segmented into Commercial Real Estate (“CRE”), which is further segmented into Owner Occupied (“CRE OO”), Non-owner Occupied (“CRE NOO”), and Multifamily Residential, Residential Real Estate (“RRE”), Commercial and Industrial (“C&I”), Home Equity Lines of Credit (“HELOC”), Construction and Other (“Construction”), and Consumer Installment Loans. The commercial real estate loan segments consist of loans made to finance the activities of commercial real estate owners and operators and certain agricultural loans. The residential real estate and HELOC loan segments consist of loans made to finance the activities of residential homeowners. The C&I loan segment consists of loans made to finance the activities of commercial customers and certain agricultural loans. The consumer loan segment consists primarily of installment loans and overdraft lines of credit connected with customer deposit accounts. The increases in the allowance for credit loss for the C&I, RRE, and HELOC portfolios were partially offset by a decrease in the allowance for the CRE, Construction, and Consumer Installment portfolios. Historical credit loss experience is the basis for the estimation of expected credit losses. We apply historical loss rates to pools of loans with similar risk characteristics. After consideration of the historic loss calculation, management applies qualitative adjustments to reflect the current conditions and reasonable and supportable forecasts not The Bank has elected to exclude accrued interest receivable from the measurement of its ACL. When a loan is placed on nonaccrual status, any outstanding accrued interest is reversed against interest income. The ACL for individual loans begins with the use of normal credit review procedures to identify whether a loan no 1 2 3 not three 1 2 3 not Allowance for Loan Losses Prior to adopting ASU 2016 13 Prior to the adoption of ASU 2016 13 326 The allowance for loan and lease losses represents the amount that management estimates are adequate to provide for probable loan losses inherent in the loan portfolio. The allowance method is used in providing for loan losses. Accordingly, all loan losses are charged to the allowance, and all recoveries are credited to it. The allowance for loan and lease losses is established through a provision for loan losses charged to operations. The provision is based on management’s periodic evaluation of the adequacy of the allowance for loan and lease losses, which encompasses the overall risk characteristics of the various portfolio segments, experience with losses, the impact of economic conditions on borrowers, and other relevant factors. The estimates used in determining the adequacy of the allowance for loan and lease losses, including the amounts and timing of future cash flows expected on impaired loans, are particularly susceptible to a significant change in the near term. The allowance consists of specific, general, and unallocated components. The specific component relates to loans that are classified as impaired. For loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers pools of loans by loan class including commercial loans not ● national and local economic trends and conditions; ● levels of and trends in delinquency rates and nonaccrual loans; ● trends in volumes and terms of loans; ● effects of changes in lending policies; ● experience, ability, and depth of lending staff; ● value of underlying collateral; ● and concentrations of credit from a loan type, industry, and/or geographic standpoint. A majority of the Bank’s loan assets are loans to business owners of many types. The Bank makes commercial loans for real estate development and other business purposes required by the customer base. The Bank’s credit policies determine advance rates against the different forms of collateral that can be pledged against commercial loans. Typically, the majority of loans will be limited to a percentage of their underlying collateral values such as real estate values, equipment, eligible accounts receivable, and inventory. Individual loan advance rates may not 80 Residential mortgages and home equity loans are secured by the borrower’s residential real estate in either a first second 30 20 Consumer loans include installment loans, car loans, and overdraft lines of credit. The majority of these loans are unsecured. A loan is considered impaired when it is probable the borrower will not 89 not not first The Bank originates commercial and residential construction loans to developers and builders and, in some cases, to other commercial borrowers for approved construction projects. These loans are typically structured on a non-revolving basis and the draw of funds is dependent on successfully completed and verified progress of the project. These loans are generally secured by the real estate to be developed and may may For commercial loans secured by real estate, estimated fair values are determined primarily through third For commercial and industrial loans secured by non-real estate collateral, such as accounts receivable, inventory, and equipment, estimated fair values are determined based on the borrower’s financial statements, inventory reports, accounts receivable agings, equipment appraisals, or invoices. Indications of value from these sources are generally discounted based on the age of the financial information or the quality of the assets. Mortgage loans secured by one four Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Bank does not Loans whose terms are modified are classified as troubled debt restructurings if the Bank grants such borrowers concessions and it is deemed that those borrowers are experiencing financial difficulty. Concessions granted under a troubled debt restructuring generally involve a temporary reduction in interest rate or an extension of a loan’s stated maturity date. Nonaccrual troubled debt restructurings are restored to accrual status if principal and interest payments, under the modified terms, are current for six The allowance calculation methodology includes further segregation of loan classes into risk rating categories. The borrower’s overall financial condition, repayment sources, guarantors, and value of collateral, if appropriate, are evaluated annually for commercial loans or when credit deficiencies arise, such as delinquent loan payments, for commercial and consumer loans. Credit quality risk ratings include regulatory classifications of special mention, substandard, doubtful, and loss. Loans classified as special mention have potential weaknesses that deserve management’s close attention. If uncorrected, the potential weaknesses may not In addition, federal regulatory agencies, as an integral part of their examination process, periodically review the Bank’s allowance for loan losses and may may not Allowance for Credit Losses on Off-Balance Sheet Credit Exposures The Bank estimates expected credit losses over the contractual period in which the Bank is exposed to credit risk via a contractual obligation to extend credit unless that obligation is unconditionally cancellable by the Bank. The allowance for credit losses on off-balance sheet credit exposures is adjusted through credit loss expense. 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.

Fair Value Disclosures [Text Block]	NOTE 5 Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for an asset or liability in an orderly transaction between market participants at the measurement date. GAAP establishes a fair value hierarchy that prioritizes the use of inputs used in valuation methodologies into the following levels: Level I: Quoted prices are available in active markets for identical assets or liabilities as of the reported date. Level II: Pricing inputs are other than the quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these assets and liabilities includes items for which quoted prices are available but traded less frequently and items that are fair-valued using other financial instruments, the parameters of which can be directly observed. Level III: Assets and liabilities that have little to no not two This hierarchy requires the use of observable market data when available. The following tables present the assets measured on a recurring basis on the Consolidated Balance Sheet at their fair value by level within the fair value hierarchy.

Loans, Notes, Trade and Other Receivables Disclosure [Text Block]	NOTE 8 The Company’s primary business activity is with customers located within its local Northeastern Ohio trade area, eastern Geauga County, and contiguous counties. The Company also serves the central and western Ohio market with offices in Ada, Bellefontaine, Dublin, Kenton, Marysville, Plain City, Powell, Sunbury, and Westerville, Ohio. Commercial, residential, consumer, and agricultural loans are granted. Although the Company has a diversified loan portfolio, loans outstanding to individuals and businesses are dependent upon the local economic conditions in the Company’s immediate trade area. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff generally are reported at their outstanding unpaid principal balances net of the allowance for credit losses. Interest income is recognized on the accrual method. The accrual of interest is discontinued on a loan when management believes, after considering economic and business conditions, the borrower’s financial condition is such that the collection of interest is doubtful. Interest payments received on nonaccrual loans are applied against the unpaid principal balance until accrual status is restored. Loan origination fees and certain direct loan origination costs are deferred with the net amount amortized over the contractual life of the loan as an adjustment of the related loan’s yield. The following tables summarize the primary segments of the loan portfolio (in thousands): June 30, December 31, 2023 2022 Commercial real estate: Owner occupied $ 187,919 $ 191,748 Non-owner occupied 385,846 380,580 Multifamily 58,579 58,251 Residential real estate 312,196 296,308 Commercial and industrial 209,349 195,602 Home equity lines of credit 126,894 128,065 Construction and Other 118,851 94,199 Consumer installment 9,801 8,119 Total loans 1,409,435 1,352,872 Less: Allowance for credit losses (20,591 ) (14,438 ) Net loans $ 1,388,844 $ 1,338,434 The Company’s loan portfolio is segmented to a level that allows management to monitor risk and performance. The portfolio is segmented into CRE, which is further segmented into Owner CRE OO, CRE NOO, and Multifamily Residential, RRE, C&I, HELOC, Construction, and Consumer Installment Loans. The commercial real estate loan segments consist of loans made to finance the activities of commercial real estate owners and operators and certain agricultural loans. The residential real estate and HELOC loan segments consist of loans made to finance the activities of residential homeowners. The C&I loan segment consists of loans made to finance the activities of commercial customers and certain agricultural loans. The consumer loan segment consists primarily of installment loans and overdraft lines of credit connected with customer deposit accounts. The increases in the allowance for credit loss for the C&I, RRE, and HELOC portfolios were partially offset by a decrease in the allowance for the CRE, Construction, and Consumer Installment portfolios. Management evaluates individual loans in all of the commercial segments for possible impairment based on guidelines established by the Board of Directors. Loans are individually analyzed when, based on current information and events, the Company will probably be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in evaluating credit loss include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record, and the amount of the shortfall concerning the principal and interest owed. Once the determination has been made that a loan is going to be individually analyzed, the determination of whether a specific allocation of the allowance is necessary is measured by comparing the recorded investment in the loan to the fair value of the loan using one not Management uses a nine first five not not not To help ensure that risk ratings are accurate and reflect the present and future capacity of borrowers to repay a loan as agreed, the Company has a structured loan rating process with several layers of internal and external oversight. Generally, consumer and residential mortgage loans are included in the Pass categories unless a specific action, such as payment delinquency, bankruptcy, repossession, or death, occurs to raise awareness of a possible credit quality loss. The Company’s Commercial Loan Officers are responsible for the timely and accurate risk rating of the loans in their portfolios at origination and on an ongoing basis. The Credit Department performs an annual review of all commercial relationships with loan balances of $750,000 or greater. Confirmation of the appropriate risk grade is included in the review on an ongoing basis. The Company engages an external consultant to conduct loan reviews on a semiannual basis. Generally, the external consultant reviews a sample of commercial relationships greater than $250,000 and criticized relationships greater than $150,000. Detailed reviews, including plans for resolution, are performed on criticized loans on at least a quarterly basis. Loans in the Special Mention and Substandard categories that are collectively evaluated for impairment are given separate consideration in the determination of the allowance.

Business Combination Disclosure [Text Block]	NOTE 10 BUSINESS COMBINATION As described in Note 1, December 1, 2022, one may one The Company also recorded an identifiable intangible asset representing the core deposit base of Liberty. The discounted cash flow method was used in valuing this intangible. This method is based upon the principle of future benefits; economic value is based on anticipated future benefits as measured by cash flows expected to occur in the future. The estimated future cash flows are converted to a value indicator by determining the present value of the cash flows using a discount rate. The discount rate is based on the nature of the business, the level of risk, and the expected stability of the estimated future cash flows. The higher the risk, the higher the discount rate, and the lower the value indicator. Time deposit fair values were estimated using an income approach. The methodology entailed discounting the contractual cash flows of the instruments over their remaining contractual lives at prevailing market rates. Interest and principal payments were projected for each category of CDs over the period from the valuation date to the maturity date. These payments represent future cash flows to be paid to depositors until maturity. Using appropriate market interest rates for each category of CDs, the future cash flows were discounted to their present value equivalents. Loan fair value, at the time of the merger, used the income approach to estimate the fair value of the loans. The Bank’s loans are valued on an individual basis. As of June 30, 2023, Middlefield recorded goodwill and intangibles associated with the purchase of Liberty totaling $16.7 million. Goodwill is not not June 30, 2023. Identifiable intangibles are amortized to their estimated residual values over the expected useful lives. Such lives are also periodically reassessed to determine if any amortization period adjustments are required.
