Organization Consolidation And Presentation Of Financial Statements [Abstract]
Basis of Accounting and Consolidation	Note 1 -- Basis of Accou nting and Consolidation The unaudited condensed consolidated financial statements include the accounts of First Mid Bancshares, Inc. (“Company”) and its wholly owned subsidiaries: First Mid Bank & Trust, N.A. (“First Mid Bank”), First Mid Wealth Management Company, First Mid Insurance Group, Inc. (“First Mid Insurance”), and First Mid Captive, Inc. All significant intercompany balances and transactions have been eliminated in consolidation. The financial information reflects all adjustments which, in the opinion of management, are necessary for a fair presentation of the results of the interim periods ended March 31, 2023 and 2022, and all such adjustments are of a normal recurring nature. Certain amounts in the prior year’s consolidated financial statements may have been reclassified to conform to the March 31, 2023 presentation and there was no impact on net income or stockholders’ equity. The results of the interim period ended March 31, 2023 are not necessarily indicative of the results expected for the year ending December 31, 2023. The Company operates as a one-segment entity for financial reporting purposes. The 2022 year-end consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. The unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and do not include all the information required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements and related footnote disclosures although the Company believes that the disclosures made are adequate to make the information not misleading. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2022 Annual Report on Form 10-K. Blackhawk Bancorp, Inc On March 21, 2023, First Mid Bancshares, Inc. (“First Mid”) and Eagle Sub LLC, a newly formed Wisconsin limited liability company and wholly-owned subsidiary of First Mid (“Merger Sub”), entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Blackhawk Bancorp, Inc., a Wisconsin corporation (“Blackhawk”), pursuant to which, among other things, First Mid agreed to acquire 100 % of the issued and outstanding shares of Blackhawk pursuant to a business combination whereby Blackhawk will merge with and into Merger Sub, whereupon the separate corporate existence of Blackhawk will cease and Merger Sub will continue as the surviving company and a wholly-owned subsidiary of First Mid (the “Merger”). Subject to the terms and conditions of the Merger Agreement, at the effective time of the Merger, each share of common stock, par value $ 0.01 per share, of Blackhawk issued and outstanding immediately prior to the effective time of the Merger (other than shares held in treasury by Blackhawk and dissenting shares) will be converted into and become the right to receive 1.15 shares of common stock, par value $ 4.00 per share, of First Mid and cash in lieu of fractional shares, less any applicable taxes required to be withheld, and subject to certain potential adjustments. On an aggregate basis, the total consideration payable by First Mid at the closing of the Merger to Blackhawk’s shareholders and equity award holders is approximately 3,330,176 shares of First Mid common stock. Blackhawk’s outstanding stock equity awards will fully vest upon consummation of the Merger. It is anticipated that Blackhawk’s wholly-owned bank subsidiary, Blackhawk Bank (“Blackhawk Bank”), will be merged with and into First Mid’s wholly-owned bank subsidiary, First Mid Bank & Trust, N.A. (“First Mid Bank”), at a date following completion of the Merger. At the time of the bank merger, Blackhawk Bank’s banking offices will become branches of First Mid Bank. The Merger is anticipated to be completed in the third quarter of 2023 and is subject to the satisfaction of customary closing conditions in the Merger Agreement and the approval of the appropriate regulatory authorities. Delta Bancshares Company On July 28, 2021, the Company and Brock Sub LLC, a newly formed Delaware limited liability company and wholly-owned subsidiary of the Company (“Delta Merger Sub”), entered into an Agreement and Plan of Merger (the “Delta Merger Agreement”) with Delta Bancshares Company, a Missouri corporation (“Delta”), pursuant to which, among other things, the Company agreed to acquire 100 % of the issued and outstanding shares of Delta pursuant to a business combination whereby Delta merged with and into Merger Sub, whereupon the separate corporate existence of Delta ceased and Merger Sub continued as the surviving company and a wholly-owned subsidiary of First Mid (the “Delta Merger”). The Delta Merger was completed on February 14, 2022. Subject to the terms and conditions of the Merger Agreement, at the effective time of the Delta Merger, each share of common stock, par value $ 10.00 per share, of Delta issued and outstanding immediately prior to the effective time of the Delta Merger (other than shares held in treasury by Delta) converted into and became the right to receive cash and shares of common stock, par value $ 4.00 per share, of the Company and cash in lieu of fractional shares, less any applicable taxes required to be withheld, and subject to certain potential adjustments. On an aggregate basis, the total consideration paid by the Company at the closing of the Delta Merger to Delta’s shareholders and option holders was approximately $ 15.15 million in cash and 2,292,270 shares of Company common stock. Delta’s outstanding stock options vested upon consummation of the Delta Merger, and all outstanding Delta options that were unexercised prior to the effective time of the Delta Merger were cashed out. Delta’s wholly owned bank subsidiary, Jefferson Bank, was merged with and into First Mid Bank during the second quarter of 2022. At the time of the bank merger, Jefferson Bank’s banking offices became branches of First Mid Bank. Website The Company maintains a website at www.firstmid.com . All periodic and current reports of the Company and amendments to these reports filed with the Securities and Exchange Commission (“SEC”) can be accessed, free of charge, through this website as soon as reasonably practicable after these materials are filed with the SEC. General Litigation The Company is subject to claims and lawsuits that arise primarily in the ordinary course of business. It is the opinion of management that the disposition or ultimate resolution of such claims and lawsuits will not have a material adverse effect on the consolidated financial position, results of operations and cash flows of the Company. Stock Plans At the Annual Meeting of Stockholders held April 26, 2017, the stockholders approved the First Mid-Illinois Bancshares, Inc. 2017 Stock Incentive Plan (“SI Plan”). The SI Plan was implemented to succeed the Company’s 2007 Stock Incentive Plan, which had a ten-year term. The SI Plan is intended to provide a means whereby directors, employees, consultants and advisors of the Company and its subsidiaries may sustain a sense of proprietorship and personal involvement in the continued development and financial success of the Company and its subsidiaries, thereby advancing the interests of the Company and its stockholders. Accordingly, directors and selected employees, consultants and advisors may be provided the opportunity to acquire shares of common stock of the Company on the terms and conditions established in the SI Plan. Following the stockholders’ approval at the 2021 annual meeting of the Company, a maximum of 399,983 shares of common stock may be issued under the SI Plan. There have been no stock options awarded under any Company plan since 2008. The Company has awarded 60,550 and 26,000 shares of restricted stock during the three months ended March 31, 2023 and 2022, respectively, and 37,900 and 37,150 restricted stock units during the three months ended March 31, 2023 and 2022 , respectively. Employee Stock Purchase Plan At the Annual Meeting of Stockholders held April 25, 2018, the stockholders approved the First Mid-Illinois Bancshares, Inc. Employee Stock Purchase Plan (“ESPP”). The ESPP is intended to promote the interests of the Company by providing eligible employees with the opportunity to purchase shares of common stock of the Company at a 15 % discount through payroll deductions. The ESPP is also intended to qualify as an employee stock purchase plan under Section 423 of the Internal Revenue Code. A maximum of 600,000 shares of common stock may be issued under the ESPP. During the three months ended March 31, 2023 and 2022, 7,963 shares and 3,149 shares, respectively, were issued pursuant to the ESPP. Captive Insurance Company First Mid Captive, Inc. (the “Captive"), a wholly owned subsidiary of the Company which was formed and began operations in December 2019, is a Nevada-based captive insurance company. The Captive insures against certain risks unique to operations of the Company and its subsidiaries for which insurance may not be currently available or economically feasible in today's insurance marketplace. The Captive pools resources with several other similar insurance company subsidiaries of financial institutions to spread a limited amount of risk among themselves. The Captive is subject to regulations of the State of Nevada and undergoes periodic examinations by the Nevada Division of Insurance. It has elected to be taxed under Section 831(b) of the Internal Revenue Code. Pursuant to Section 831(b), if gross premiums do not exceed $ 2,650,000 , then the Captive is taxable solely on its investment income. The Captive is included in the Company's consolidated financial statements and its federal income return. Bank Owned Life Insurance First Mid Bank has purchased life insurance policies on certain senior management. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts that are probable at settlement. Revenue Recognition Accounting Standards Codification 606, Revenue from Contracts with Customers (“ASC 606”), establishes a revenue recognition model for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity's contracts to provide goods or services to customers. Most of the Company’s revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as loans and investment securities, and revenue related to mortgage servicing activities, which are subject to other accounting standards. A description of the revenue-generating activities that are within the scope of ASC 606, and included in other income in the Company’s condensed consolidated statements of income are as follows: Trust revenues. The Company generates fee income from providing fiduciary services through its subsidiary, First Mid Wealth Management Company. Fees are billed in arrears based upon the preceding period account balance. Revenue from farm management services is recorded when the service is complete, for example when crops are sold. Brokerage commissions. Revenue is recorded at the beginning of each quarter through billing to customers based on the account asset size on the last day of the previous quarter. If a withdrawal of funds takes place, a prorated refund may occur; this is reflected within the same quarter as the original billing occurred. All performance obligations are met within the same quarter that the revenue is recorded. Insurance commissions. The Company’s insurance agency subsidiary, First Mid Insurance, receives commissions on premiums of new and renewed business policies. First Mid Insurance records commission revenue on direct bill policies as the cash is received. For agency bill policies, First Mid Insurance retains its commission portion of the customer premium payment and remits the balance to the carrier. In both cases, the entire performance obligation is held by the carriers. Service charges on deposits. The Company generates revenue from fees charged for deposit account maintenance, overdrafts, wire transfers, and check fees. The revenue related to deposit fees is recognized at the time the performance obligation is satisfied. ATM/debit card revenue. The Company generates revenue through service charges on the use of its ATM machines and interchange income from the use of Company issued credit and debit cards. The revenue is recognized at the time the service is used and the performance obligation is satisfied. Other income. Treasury management fees and lock box fees are received and recorded after the service performance obligation is completed. Merchant bank card fees are received from various vendors; however, the performance obligation is with the vendors. The Company records gains on the sale of loans and the sale of OREO properties after the transactions are complete and transfer of ownership has occurred. As each of the Company’s facilities is in markets with similar economies, no disaggregation of revenue is necessary. Accumulated Other Comprehensive Loss The components of accumulated other comprehensive loss included in stockholders’ equity as of March 31, 2023 and December 31, 2022 are as follows (in thousands): Unrealized Losses on Securities March 31, 2023 Net unrealized losses on securities available-for-sale $ ( 194,225 ) Tax benefit 56,324 Balance at March 31, 2023 $ ( 137,901 ) December 31, 2022 Net unrealized losses on securities available-for-sale $ ( 213,387 ) Tax benefit 61,880 Balance at December 31, 2022 $ ( 151,507 ) Amounts reclassified from accumulated other comprehensive loss and the affected line items in the statements of income during the three months ended March 31, 2023 and 2022, were as follows (in thousands): Amounts Reclassified from Three months ended March 31, 2023 2022 Affected Line Item in the Statements of Income Realized losses on available-for-sale securities $ ( 46 ) $ — Securities (loss) gains, net Tax effect 13 — Income taxes Total reclassifications out of accumulated other comprehensive income (loss) $ ( 33 ) $ — Net reclassified amount See “Note 3 – Investment Securities” for more detailed information regarding unrealized losses on available-for-sale securities. Adoption of New Accounting Guidance Accounting Standards Update 2022-02, Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”). In March 2022, FASB issued ASU 2022-02. The amendments in this update eliminate the accounting guidance and related disclosures for TDRs by creditors in Subtopic 310-40, Receivables—Troubled Debt Restructurings by Creditors , while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty and requiring an entity to disclose current-period gross writeoffs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost . The amendments in this update were effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years and are applied prospectively, except with respect to the recognition and measurement of TDRs, where an entity has the option to apply a modified retrospective transition method. The adoption of this accounting guidance resulted in updated disclosures within the Company's consolidated financial statements.

Receivables [Abstract]
Loans and Allowance for Credit Losses	Note 4 – Loans and Allowance for Credit Losses Loans are stated at amortized cost net of an allowance for credit losses. Amortized cost is the unpaid principal net of unearned premiums and discounts, and net deferred origination fees and costs. Deferred loan origination fees are reduced by loan origination costs and are amortized to interest income over the life of the related loan using methods that approximated the effective interest rate method. Interest on substantially all loans is credited to income based on the principal amount outstanding. A summary of loans at March 31, 2023 and December 31, 2022 follows (in thousands): March 31, 2023 December 31, 2022 Construction and land development $ 159,266 $ 144,387 Agricultural real estate 402,283 410,790 1-4 family residential properties 424,373 440,018 Multifamily residential properties 302,506 295,073 Commercial real estate 2,009,524 2,036,243 Loans secured by real estate 3,297,952 3,326,511 Agricultural loans 146,679 166,695 Commercial and industrial loans 1,080,004 1,085,004 Consumer loans 88,404 97,730 All other loans 156,210 159,499 Total gross loans 4,769,249 4,835,439 Less: loans held for sale 999 338 4,768,250 4,835,101 Less: Net deferred loan fees, premiums and discounts 8,618 9,227 Allowance for credit losses 58,223 59,093 Net loans $ 4,701,409 $ 4,766,781 Loans expected to be sold are classified as held for sale in the consolidated financial statements and are recorded at fair value, taking into consideration future commitments to sell the loans. These loans are primarily for 1-4 family residential properties. Accrued interest on loans, which is excluded from the amortized cost of the balances above, totaled $ 22.6 million and $ 23.0 million at March 31, 2023 and December 31, 2022, respectively. Most of the Company’s business activities are with customers located near the Company's branch locations in Illinois, Missouri, and Texas. At March 31, 2023, the Company’s loan portfolio included $ 548.8 million of loans to borrowers whose businesses are directly related to agriculture. Of this amount, $ 422.4 million was concentrated in corn and other grain farming. Total loans to borrowers whose businesses are directly related to agriculture decreased $ 28.4 million from $ 577.2 million at December 31, 2022 due to seasonal timing of cash flow requirements. Loans concentrated in corn and other grain farming decreased $ 22.8 million from $ 445.2 million at December 31, 2022. The Company's underwriting practices include collateralization of loans. Any extended period of low commodity prices, drought conditions, significantly reduced yields on crops and/or reduced levels of government assistance to the agricultural industry could result in an increase in the level of problem agriculture loans and potentially result in loan losses within the agricultural portfolio. In addition, the Company has $ 211.4 million of loans to motels and hotels. The performance of these loans is dependent on borrower specific issues as well as the general level of business and personal travel within the region. While the Company adheres to sound underwriting standards, a prolonged period of reduced business or personal travel could result in an increase in nonperforming loans to this business segment and potentially in loan losses. The Company also has $ 945.7 million of loans to lessors of non-residential buildings, and $ 462.8 million of loans to lessors of residential buildings and dwellings. The structure of the Company’s loan approval process is based on progressively larger lending authorities granted to individual loan officers, loan committees, and ultimately the board of directors. Outstanding balances to one borrower or affiliated borrowers are limited by federal regulation and most borrowers are below regulatory thresholds. The Company can occasionally have outstanding balances to one borrower up to but not exceeding the regulatory threshold should underwriting guidelines warrant. Most of the Company’s loans are to businesses located in the geographic market areas served by the Company’s branch bank system. Additionally, a significant portion of the collateral securing the loans in the portfolio is located within the Company’s primary geographic footprint. In general, the Company adheres to loan underwriting standards consistent with industry guidelines for all loan segments. The Company’s lending can be summarized into the following primary areas: Commercial Real Estate Loans. Commercial real estate loans are generally comprised of loans to small business entities to purchase or expand structures in which the business operations are housed, loans to owners of real estate who lease space to non-related commercial entities, loans for construction and land development, loans to hotel operators, and loans to owners of multi-family residential structures, such as apartment buildings. Commercial real estate loans are underwritten based on historical and projected cash flows of the borrower and secondarily on the underlying real estate pledged as collateral on the debt. For the various types of commercial real estate loans, minimum criteria have been established within the Company’s loan policy regarding debt service coverage while maximum limits on loan-to-value and amortization periods have been defined. Maximum loan-to-value ratios range from 65 % to 80 % depending upon the type of real estate collateral, while the desired minimum debt coverage ratio is 1.20x . Amortization periods for commercial real estate loans are generally limited to twenty or twenty five years , depending on the loan-to-value. The Company’s commercial real estate portfolio is below the thresholds that would designate a concentration in commercial real estate lending, as established by the federal banking regulators. Commercial and Industrial Loans. Commercial and industrial loans are primarily comprised of working capital loans used to purchase inventory and fund accounts receivable that are secured by business assets other than real estate. These loans are generally written for one year or less. Also, equipment financing is provided to businesses with these loans generally limited to 80 % of the value of the collateral and amortization periods limited to seven years . Commercial loans are often accompanied by a personal guaranty of the principal owners of a business. Like commercial real estate loans, the underlying cash flow of the business is the primary consideration in the underwriting process. The financial condition of commercial borrowers is monitored at least annually with the type of financial information required determined by the size of the relationship. Measures employed by the Company for businesses with higher risk profiles include the use of government- assisted lending programs through the Small Business Administration and U.S. Department of Agriculture. Agricultural and Agricultural Real Estate Loans. Agricultural loans are generally comprised of seasonal operating lines to cash grain farmers to plant and harvest corn and soybeans and term loans to fund the purchase of equipment. Agricultural real estate loans are primarily comprised of loans for the purchase of farmland. Specific underwriting standards have been established for agricultural-related loans including the establishment of projections for each operating year based on industry developed estimates of farm input costs and expected commodity yields and prices. Operating lines are typically written for one year and secured by the crop. Loan-to-value ratios on loans secured by farmland generally do not exceed 65 % and have amortization periods limited to twenty-five years . Federal government-assistance lending programs through the Farm Service Agency are used to mitigate the level of credit risk when deemed appropriate. Residential Real Estate Loans. Residential real estate loans generally include loans for the purchase or refinance of residential real estate properties consisting of one-to-four units and home equity loans and lines of credit. The Company sells most of its long-term fixed rate residential real estate loans to secondary market investors. The Company also releases the servicing of these loans upon sale. Residential real estate loans are typically underwritten to conform to industry standards including criteria for maximum debt-to-income and loan-to-value ratios as well as minimum credit scores. Loans secured by first liens on residential real estate held in the portfolio typically do not exceed 80 % of the value of the collateral and have amortization periods of twenty-five years or less. The Company does not originate subprime mortgage loans. Consumer Loans. Consumer loans are primarily comprised of loans to individuals for personal and household purposes such as the purchase of an automobile or other living expenses. Minimum underwriting criteria have been established that consider credit score, debt-to-income ratio, employment history, and collateral coverage. Typically, consumer loans are set up on monthly payments with amortization periods based on the type and age of the collateral. Other Loans. Other loans consist primarily of loans to municipalities to support community projects such as infrastructure improvements or equipment purchases. Underwriting guidelines for these loans are consistent with those established for commercial loans with the additional repayment source of the taxing authority of the municipality. Allowance for Credit Losses The allowance for credit losses represents the Company’s best estimate of the reserve necessary to adequately account for probable losses expected over the remaining contractual life of the assets. The provision for credit losses is the charge against current earnings that is determined by the Company as the amount needed to maintain an adequate allowance for credit losses. In determining the adequacy of the allowance for credit losses, and therefore the provision to be charged to current earnings, the Company relies predominantly on a disciplined credit review and approval process that extends to the full range of the Company’s credit exposure. The review process is directed by the overall lending policy and is intended to identify, at the earliest possible stage, borrowers who might be facing financial difficulty. Factors considered by the Company in evaluating the overall adequacy of the allowance include historical net loan losses, the level and composition of nonaccrual, past due and modified loans, trends in volumes and terms of loans, effects of changes in risk selection and underwriting standards or lending practices, lending staff changes, concentrations of credit, industry conditions and the current economic conditions in the region where the Company operates. The Company estimates the appropriate level of allowance for credit losses by evaluating large individually evaluated loans separately from non-individually evaluated loans. Individually Evaluated Loans The Company individually evaluates certain loans for impairment. In general, these loans have been internally identified via the Company’s loan grading system as credits requiring management’s attention due to underlying problems in the borrower’s business or collateral concerns. This evaluation considers expected future cash flows, the value of collateral and other factors that may impact the borrower’s ability to make payments when due. For loans greater than $ 250,000 , impairment is individually measured each quarter using one of three alternatives: (1) the present value of expected future cash flows discounted at the loan’s effective interest rate; (2) the loan’s observable market price, if available; or (3) the fair value of the collateral less costs to sell for collateral dependent loans and loans for which foreclosure is deemed to be probable. A specific allowance is assigned when expected cash flows or collateral are less than the carrying amount of the loan. The carrying value of the loan reflects reductions from prior charge-offs. Non-Individually Evaluated Loans Non-individually evaluated loans comprise the vast majority of the Company’s total loan portfolio and include loans in accrual status and those credits not identified as modified loans. A small portion of these loans are considered “criticized” due to the risk rating assigned reflecting elevated credit risk due to characteristics, such as a strained cash flow position, associated with the individual borrowers. Criticized loans are those assigned risk ratings of Special Mention, Substandard, or Doubtful. To determine the allowance, the loan portfolio is segmented based on similar risk characteristics. The allowance for credit losses is estimated using a discounted cash flow (DCF) methodology. The DCF projects future cash flows over the life of the loan portfolio. Probability of default (PD) and loss given default (LGD) are key components in calculating expected losses in this model. The PD is forecasted using a regression model that determines the likelihood of default with a forward-looking forecast of unemployment rates. The LGD is the percentage of defaulted loans that is ultimately charged off. The allowance is calculated as the net present value of the expected cash flows less the amortized cost basis of the loans. Prior to 2022, the allowance for credit losses was measured on a collective (pool) basis for non-individually evaluated loans with similar risk characteristics. Historical credit loss experience provided the basis for the estimate of expected credit losses. Adjustments to expected losses are made using qualitative factors for relevant to each loan segment including merger & acquisition activity, economic conditions, changes in policies, procedures & underwriting, and concentrations. In addition, a forecast, using reasonable and supportable future conditions, is prepared that is used to estimate expected changes to existing and historical conditions in the current period. The Company also considers specific current economic events occurring globally, in the U.S. and in its local markets. Events considered include the status of trade agreements with China, scheduled increases in minimum wage and changes to the minimum salary threshold for overtime provisions, current and projected unemployment rates, current and projected grain and oil prices and economies of local markets where customers work and operate. Within each pool, risk elements are evaluated that have specific impacts to the borrowers within the pool. These, along with the general risks and events, and the specific lending policies and procedures by loan type described above, are analyzed to estimate the qualitative factors used to adjust the historical loss rates. During the current period, the following assumptions and factors were considered when determining the historical loss rate and any potential adjustments by loan pool. Construction and Land Development Loans. Historical losses in this segment remain very low. While staffing shortages and supply chain disruptions cause risk in this segment, most projects are associated with financially strong borrowers. The qualitative factors for this segment were not changed. Agricultural Real Estate Loans. Historical losses in the segment remain very low. Farmland values have increased over an extended period of time and there are no indications that this will change in the next year. There was no change to the qualitative factors for this segment. 1- 4 Family Residential Properties Loans. The loan segment has remained stable throughout the last several years. Both adversely classified and past dues have been consistent. There was no change to the qualitative factors for this segment. Commercial Real Estate Loans. This segment includes the Company's largest balances and the largest allowance for credit losses. The qualitative factors on both non-owner occupied and owner-occupied loans for this segment were increased due to actual and expected changes in economic and business conditions. Agricultural Loans. Losses in this segment are very low. Commodity prices have been elevated and yields have been strong. The qualitative factors of this segment was not changed. Commercial and Industrial Loans. This segment includes the second largest balance of allowance for credit losses. The qualitative factors for this segment was increased due to actual and expected changes in economic and business conditions. Consumer Loans. This segment is the smallest portion of the Company's loan portfolio. There was no significant change to the qualitative factors. Acquired Loans. Prior to January 1, 2020 loans acquired with evidence of credit deterioration since origination and for which it was probable that all contractually required payments would not be collected were considered purchased credit impaired at the time of acquisition. Purchase credit-impaired ("PCI") loans were accounted for under ASC 310-30, Receivables--Loans and Debt Securities Acquired with Deteriorated Credit Quality ("ASC 310-30"), and were initially measured at fair value, which included the estimated future credit losses expected to be incurred over the life of the loan. Accordingly, an allowance for credit losses related to these loans was not carried over and recorded at the acquisition date. The cash flows expected to be collected were estimated using current key assumptions, such as default rates, value of underlying collateral, severity and prepayment speeds. Subsequent to January 1, 2020, loans acquired in a business combination that have experienced more-than-insignificant deterioration in credit quality since origination are considered purchased credit deteriorated (“PCD”) loans. At the acquisition date, an estimate of expected credit losses is made for groups of PCD loans with similar risk characteristics and individual PCD loans without similar risk characteristics. This initial allowance for credit losses is allocated to individual PCD loans and added to the purchase price or acquisition date fair values to establish the initial amortized cost basis of the PCD loans. As the initial allowance for credit losses is added to the purchase price, there is no credit loss expense recognized upon acquisition of a PCD loan. Any difference between the unpaid principal balance of PCD loans and the amortized cost basis is considered to relate to noncredit factors and results in a discount or premium. Discounts and premiums are recognized through interest income on a level-yield method over the life of the loans. For acquired loans not deemed purchased credit deteriorated at acquisition, the differences between the initial fair value and the unpaid principal balance are recognized as interest income on a level-yield basis over the lives of the related loans. At the acquisition date, an initial allowance for expected credit losses is estimated and recorded as credit loss expense. The subsequent measurement of expected credit losses for all acquired loans is the same as the subsequent measurement of expected credit losses for originated loans.

The Company’s policy is to promptly charge these loans off in the period the uncollectible loss is reasonably determined. For all loan portfolio segments except 1-4 family residential properties and consumer, the Company promptly charges-off loans, or portions thereof, when available information confirms that specific loans are uncollectible based on information that includes, but is not limited to, (1) the deteriorating financial condition of the borrower, (2) declining collateral values, and/or (3) legal action, including bankruptcy, that impairs the borrower’s ability to adequately meet its obligations. For individually evaluated loans that are considered solely collateral dependent, a partial charge-off is recorded when a loss has been confirmed by an updated appraisal or other appropriate valuation of the collateral. The Company charges-off 1-4 family residential and consumer loans, or portions thereof, when the Company reasonably determines the amount of the loss. The Company adheres to time frames established by applicable regulatory guidance which provides for the charge-down of 1-4 family first and junior lien mortgages to the net realizable value less costs to sell when the loan is 180 days past due, charge-off of unsecured open-end loans when the loan is 180 days past due, and charge down to the net realizable value when other secured loans are 120 days past due. Loans at these respective delinquency thresholds for which the Company can clearly document that the loan is both well-secured and in the process of collection, such that collection will occur regardless of delinquency status, need not be charged off. The following table presents the amortized cost basis of collateral-dependent loans by class of loans that were individually evaluated to determine expected credit losses, and the related allowance for credit losses, as of March 31, 2023 (in thousands): Collateral Allowance Real Estate Business Other Total for Credit Construction and land development $ 440 $ — $ — $ 440 $ 211 Agricultural real estate — — 16 16 — 1-4 family residential properties 84 — — 84 — Multifamily residential properties 1,151 — — 1,151 — Commercial real estate 5,674 — — 5,674 — Loans secured by real estate 7,349 — 16 7,365 211 Agricultural loans — — — — — Commercial and industrial loans 320 156 — 476 53 Consumer loans — — — 0 — Total loans $ 7,669 $ 156 $ 16 $ 7,841 $ 264 Credit Quality The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, collateral support, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis is performed on a continuous basis. The Company uses the following definitions for risk ratings which are commensurate with a loan considered “criticized”: Special Mention. Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution’s credit position at some future date. Substandard. Loans classified as substandard are inadequately protected by the current sound-worthiness and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful. Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, based on currently existing factors, conditions and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered pass rated loans.

Goodwill And Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets	Note 5 -- Goodwill and Intangible Assets The Company has goodwill from business combinations, intangible assets from branch acquisitions, identifiable intangible assets assigned to core deposit relationships and customer lists of First Mid Wealth Management Company and First Mid Insurance. The following table presents gross carrying value and accumulated amortization by major intangible asset class as of March 31, 2023 and December 31, 2022 (in thousands): March 31, 2023 December 31, 2022 Gross Carrying Accumulated Gross Carrying Accumulated Goodwill not subject to amortization (effective 1/1/02) $ 144,172 $ 3,760 $ 144,172 $ 3,760 Intangibles from branch acquisition 3,015 3,015 3,015 3,015 Core deposit intangibles 45,355 29,481 45,355 28,432 Other intangibles 20,782 9,007 20,782 8,551 $ 213,324 $ 45,263 $ 213,324 $ 43,758 During the first quarter of 2022, goodwill of $ 28.6 million was provisionally recorded for the acquisition and merger of Delta Bancshares Company.

Repurchase Agreements And Other Borrowings [Abstract]
Repurchase Agreements and Other Borrowings	Note 6 -- Repurchase Agreements and Other Borrowings Securities sold under agreements to repurchase were $ 228.7 million at March 31, 2023, an increase of $ 7.3 million from $ 221.4 million at December 31, 2022. The increase during the first three months of 2023 was primarily due to changes in business cash flow needs. All the transactions have overnight maturities with a weighted average rate of 2.83 % . The right of setoff for a repurchase agreement resembles a secured borrowing, whereby the collateral pledged by the Company would be used to settle the fair value of the repurchase agreement should the Company be in default (e.g., declare bankruptcy), the Company could cancel the repurchase agreement (i.e., cease payment of principal and interest), and attempt collection on the amount of collateral value in excess of the repurchase agreement fair value. The collateral is held by a third-party financial institution in the counterparty's custodial account. The counterparty has the right to sell or repledge the investment securities. For government entity repurchase agreements, the collateral is held by the Company in a segregated custodial account under a tri-party agreement. The Company is required by the counterparty to maintain adequate collateral levels. In the event the collateral fair value falls below stipulated levels, the Company will pledge additional securities. The Company closely monitors collateral levels to ensure adequate levels are maintained, while mitigating the potential of over-collateralization in the event of counterparty default. Collateral pledged by class for repurchase agreements are as follows (in thousands): March 31, 2023 December 31, 2022 US Treasury securities and obligations of U.S. government corporations and agencies $ 57,723 $ 47,775 Mortgage-backed securities: GSE: residential 170,941 173,639 Total $ 228,664 $ 221,414 FHLB borrowings, were $ 594.7 million and $ 464.7 million at March 31, 2023 and December 31, 2022, respectively.

Fair Value Disclosures [Abstract]
Fair Value of Assets and Liabilities	Note 7 -- Fair Value of Assets and Liabilities Fair value 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 measurements must maximize the use of observable inputs and minimize the use of unobservable inputs. There is a hierarchy of three levels of inputs that may be used to measure fair value: Level 1 Valuations for assets and liabilities traded in active exchange markets, such as the New York Stock Exchange. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 Valuations for assets and liabilities traded in less active dealer or broker markets. Valuations are obtained from third party pricing services for identical or comparable assets or liabilities which use observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in active markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Following is a description of the inputs and valuation methodologies used for assets measured at fair value on a recurring basis and recognized in the accompanying balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy. Available-for-Sale Securities. The fair value of available-for-sale securities is determined by various valuation methodologies. Where quoted market prices are available in an active market, securities are classified within Level 1. If quoted market prices are not available, then fair values are estimated by using quoted prices of securities with similar characteristics or independent asset pricing services and pricing models, the inputs of which are market-based or independent sources of market parameters, including but not limited to, yield curves, interest rates, volatilities, prepayments, defaults, cumulative loss projections and cash flows. Such securities are classified in Level 2 of the valuation hierarchy. In certain cases where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. Fair value determinations for Level 3 measurements of securities are the responsibility of the Treasury function of the Company. The Company contracts with a pricing specialist to generate fair value estimates on a monthly basis. The Treasury function of the Company challenges the reasonableness of the assumptions used and reviews the methodology to ensure the estimated fair value complies with accounting standards generally accepted in the United States, analyzes the changes in fair value and compares these changes to internally developed expectations and monitors these changes for appropriateness. Derivatives. The fair value of derivatives is based on models using observable market data as of the measurement date and are therefore classified in Level 2 of the valuation hierarchy. The following table presents the Company’s assets and liabilities that are measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fall as of March 31, 2023 and December 31, 2022 (in thousands): Fair Value Measurements Using Quoted Prices in Significant Significant Fair Value (Level 1) (Level 2) (Level 3) March 31, 2023 Available-for-sale securities: U.S. Treasury securities and obligations of U.S. government corporations and agencies $ 223,545 $ — $ 223,545 $ — Obligations of states and political subdivisions 284,997 — 284,997 — Mortgage-backed securities 624,272 — 624,272 — Other securities 79,884 — 69,874 10,010 Total available-for-sale securities 1,212,698 — 1,202,688 10,010 Equity securities 362 362 — — Derivative assets: interest rate swaps 3,353 — 3,353 — Total assets $ 1,216,413 $ 362 $ 1,206,041 $ 10,010 Derivative liabilities: interest rate swaps $ 2,525 $ — $ 2,525 $ — December 31, 2022 Available-for-sale securities: U.S. Treasury securities and obligations of U.S. government corporations and agencies $ 220,527 $ — $ 220,527 $ — Obligations of states and political subdivisions 287,698 — 287,698 — Mortgage-backed securities 627,880 — 627,880 — Other securities 82,880 — 73,630 9,250 Total available-for-sale securities 1,218,985 — 1,209,735 9,250 Equity securities 311 311 — — Derivative assets: interest rate swaps 4,253 — 4,253 — Total assets $ 1,223,549 $ 311 $ 1,213,988 $ 9,250 Derivative liabilities: interest rate swaps $ 3,100 $ — $ 3,100 $ — The change in fair value of assets measured on a recurring basis using significant unobservable inputs (Level 3) for the three months ended March 31, 2023 and 2022 is summarized as follows (in thousands): Three months ended March 31, 2023 Obligation of State and Political Subdivisions Other Total Beginning balance $ — $ 10,000 $ 10,000 Transfers into Level 3 — 10 10 Transfers out of Level 3 — — — Total gains or losses: Included in net income — — — Included in other comprehensive income (loss) — — — Purchases, issuances, sales and settlements: Purchases — — — Issuances — — — Sales — — — Settlements — — — Ending balance $ — $ 10,010 $ 10,010 Total gains or losses for the period included in net income attributable to the change in unrealized gains or losses related to assets and liabilities still held at the reporting date $ — $ — $ — Three months ended March 31, 2022 Obligation of State and Political Subdivisions Other Total Beginning balance $ 99 $ — $ 99 Transfers into Level 3 — — — Transfers out of Level 3 — — — Total gains or losses: Included in net income — — — Included in other comprehensive income (loss) — — — Purchases, issuances, sales and settlements: Purchases — — — Issuances — — — Sales — — — Settlements ( 99 ) — ( 99 ) Ending balance $ — $ — $ — Total gains or losses for the period included in net income attributable to the change in unrealized gains or losses related to assets and liabilities still held at the reporting date $ — $ — $ — Following is a description of the valuation methodologies used for assets measured at fair value on a nonrecurring basis and recognized in the accompanying balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy. Collateral Dependent Loans. Loans for which it is probable that the Company will not collect all principal and interest due according to contractual terms are measured for impairment. Allowable methods for determining the amount of impairment and estimating fair value include using the fair value of the collateral for collateral dependent loans. If the impaired loan is identified as collateral dependent, then the fair value method of measuring the amount of impairment is utilized. This method requires obtaining a current independent appraisal of the collateral and applying a discount factor to the value. Individually evaluated loans that are collateral dependent are classified within Level 3 of the fair value hierarchy when impairment is determined using the fair value method. Management establishes a specific allowance for individually evaluated loans that have an estimated fair value that is below the carrying value. The total carrying amount of loans for which a change in specific allowance has occurred as of March 31, 2023 was $ 1.4 million and a fair value of $ 1.2 million resulting in specific loss exposures of $ 0.3 million . When there is little prospect of collecting principal or interest, loans, or portions of loans, may be charged-off to the allowance for credit losses. Losses are recognized in the period an obligation becomes uncollectible. The recognition of a loss does not mean that the loan has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off the loan even though partial recovery may be affected in the future. Foreclosed Assets Held For Sale. Other real estate owned acquired through loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. The adjustment at the time of foreclosure is recorded through the allowance for credit losses. Due to the subjective nature of establishing the fair value when the asset is acquired, the actual fair value of the other real estate owned, or foreclosed asset could differ from the original estimate. If it is determined that fair value declines subsequent to foreclosure, a valuation allowance is recorded through noninterest expense. Operating costs associated with the assets after acquisition are also recorded as noninterest expense. Gains and losses on the disposition of other real estate owned and foreclosed assets are netted and posted to other noninterest expense. The total carrying amount of other real estate owned as of March 31, 2023 was $ 4.0 million . Other real estate owned included in the total carrying amount and measured at fair value on a nonrecurring basis during the period amounted to $ 0.2 million . Mortgage Servicing Rights. As of March 31, 2023, mortgage servicing rights had a carrying value of $ 0.3 million and a fair value of $ 0.5 million resulting in a valuation reserve of $ 0 . The fair value used to determine the valuation reserve for mortgage servicing rights was estimated using the discounted cash flow models. Due to the nature of the valuation inputs, mortgage servicing rights are classified within Level 3 of the fair value hierarchy. The following table presents the fair value measurement of assets measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the fair value measurements fall at March 31, 2023 and December 31, 2022 (in thousands): Fair Value Measurements Using Quoted Prices in Significant Significant Fair Value (Level 1) (Level 2) (Level 3) March 31, 2023 Collateral dependent loans $ 1,158 $ — $ — $ 1,158 Foreclosed assets held for sale 151 — — 151 December 31, 2022 Collateral dependent loans $ 2,548 $ — $ — $ 2,548 Foreclosed assets held for sale — — — — Sensitivity of Significant Unobservable Inputs The following table presents quantitative information about unobservable inputs used in Level 3 fair value measurements other than goodwill at March 31, 2023 and December 31, 2022.

Business Combinations [Abstract]
Business Combinations	Note 8 – Business Combinations On July 28, 2021, the Company and Brock Sub LLC, a newly formed Delaware limited liability company and wholly-owned subsidiary of the Company (“Delta Merger Sub”), entered into an Agreement and Plan of Merger (the “Delta Merger Agreement”) with Delta Bancshares Company, a Missouri corporation (“Delta”), pursuant to which, among other things, the Company agreed to acquire 100 % of the issued and outstanding shares of Delta pursuant to a business combination whereby Delta merged with and into Delta Merger Sub, whereupon the separate corporate existence of Delta ceased and Delta Merger Sub continued as the surviving company and a wholly-owned subsidiary of First Mid (the “Delta Merger”). The Delta Merger was completed on February 14, 2022. Subject to the terms and conditions of the Delta Merger Agreement, at the effective time of the Delta Merger, each share of common stock, par value $ 10.00 per share, of Delta issued and outstanding immediately prior to the effective time of the Delta Merger (other than shares held in treasury by Delta) converted into and became the right to receive cash and shares of common stock, par value $ 4.00 per share, of the Company and cash in lieu of fractional shares, less any applicable taxes required to be withheld, and subject to certain potential adjustments. On an aggregate basis, the total consideration paid by the Company at the closing of the Delta Merger to Delta’s shareholders and option holders was approximately $ 15.15 million in cash and 2,292,270 shares of Company common stock. Delta’s outstanding stock options vested upon consummation of the Delta Merger, and all outstanding Delta options that were unexercised prior to the effective time of the Delta Merger were cashed out. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805, “Business Combinations ("ASC 805"),” and accordingly the assets and liabilities were recorded at their estimated fair values as of the date of acquisition. Fair values are subject to refinement for up to one year after the closing date of February 14, 2022 as additional information regarding the closing date fair values become available. The total consideration paid was used to determine the amount of goodwill resulting from the transaction. As the total consideration paid exceeded the net assets acquired, goodwill of $ 28.2 million was recorded for the acquisition. Goodwill recorded in the transaction, which reflects the synergies and economies of scale expected from combining operations and the enhanced revenue opportunities from the Company’s service capabilities, is not tax deductible, and was all assigned to the banking segment of the Company.

Of this amount, $ 2.1 million was recognized during 2022. These costs are included in salaries and benefits, legal and professional and other expense. Of the $ 7.9 million adjustment to loans, $ 8.2 million is being accreted to interest income over the remaining term of the loans. The remaining $ 300,000 was the elimination of deferred fees and unearned discounts previously recorded by Jefferson Bank. The Company also recorded approximately $ 863,000 directly to the allowance for credit losses for loans identified as PCD. Of the $ 426 million of loans acquired, approximately $ 18.8 million was identified as PCD. The differences between fair value and acquired value of the assumed time deposits of $ 1.8 million and the assumed FHLB advances of $ 75,000 , are being amortized to interest expense over the remaining life of the liabilities. The core deposit intangible asset, with a fair value of $ 5.9 million, is being amortized on an accelerated basis over its estimated life of 10 years.

Leases [Abstract]
Leases	Note 9 -- Leases Effective January 1, 2019, the Company adopted ASU 2016-02, Leases (Topic 842). As of March 31, 2023, substantially all the Company's leases are operating leases for real estate property for bank branches, ATM locations, and office space. These leases are generally for periods of 1 to 25 years with various renewal options. The Company elected the optional transition method permitted by Topic 842. Under this method, the Company recognizes and measures leases that exist at the application date and prior comparative periods are not adjusted. In addition, the Company elected the package of practical expedients: 1. An entity need not reassess whether any expired or existing contracts contain leases. 2. An entity need not reassess the lease classification for any expired or existing leases. 3. An entity need not reassess initial direct costs for any existing leases. The Company has also elected the practical expedient, which may be elected separately or in conjunction with the package noted above, to use hindsight in determining the lease term and in assessing the right-of-use assets. This expedient must be applied consistently to all leases. Lastly, the Company has elected to use the practical expedient to include both lease and non-lease components as a single component and account for it as a lease. In addition, the Company has elected to not include short-term leases (i.e. leases with terms of twelve months or less) or equipment leases (primarily copiers) deemed immaterial, on the consolidated balance sheets. For leases in effect at January 1, 2019 and for leases commencing thereafter, the Company recognizes a lease liability and a right-of-use asset, based on the present value of lease payments over the lease term. The discount rate used in determining present value was the Company's incremental borrowing rate which is the FHLB fixed advance rate based on the remaining lease term as of January 1, 2019, or the commencement date for leases subsequently entered into. The following table contains supplemental balance sheet information related to leases (dollars in thousands): March 31, 2023 March 31, 2022 December 31, 2022 Operating lease right-of-use assets $ 15,092 $ 15,242 $ 15,774 Operating lease liabilities 15,353 15,458 16,035 Weighted-average remaining lease term (in years) 5.6 6.9 5.8 Weighted-average discount rate 2.68 % 2.67 % 2.67 % Certain of the Company's leases contain options to renew the lease; however, not all renewal options are included in the calculation of lease liabilities as they are not reasonably certain to be exercised.

Basis of Accounting and Consolidation	The unaudited condensed consolidated financial statements include the accounts of First Mid Bancshares, Inc. (“Company”) and its wholly owned subsidiaries: First Mid Bank & Trust, N.A. (“First Mid Bank”), First Mid Wealth Management Company, First Mid Insurance Group, Inc. (“First Mid Insurance”), and First Mid Captive, Inc. All significant intercompany balances and transactions have been eliminated in consolidation. The financial information reflects all adjustments which, in the opinion of management, are necessary for a fair presentation of the results of the interim periods ended March 31, 2023 and 2022, and all such adjustments are of a normal recurring nature. Certain amounts in the prior year’s consolidated financial statements may have been reclassified to conform to the March 31, 2023 presentation and there was no impact on net income or stockholders’ equity. The results of the interim period ended March 31, 2023 are not necessarily indicative of the results expected for the year ending December 31, 2023. The Company operates as a one-segment entity for financial reporting purposes. The 2022 year-end consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. The unaudited condensed consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X and do not include all the information required by U.S. generally accepted accounting principles (“GAAP”) for complete financial statements and related footnote disclosures although the Company believes that the disclosures made are adequate to make the information not misleading.

On an aggregate basis, the total consideration payable by First Mid at the closing of the Merger to Blackhawk’s shareholders and equity award holders is approximately 3,330,176 shares of First Mid common stock. Blackhawk’s outstanding stock equity awards will fully vest upon consummation of the Merger.

(the “Captive"), a wholly owned subsidiary of the Company which was formed and began operations in December 2019, is a Nevada-based captive insurance company. The Captive insures against certain risks unique to operations of the Company and its subsidiaries for which insurance may not be currently available or economically feasible in today's insurance marketplace. The Captive pools resources with several other similar insurance company subsidiaries of financial institutions to spread a limited amount of risk among themselves. The Captive is subject to regulations of the State of Nevada and undergoes periodic examinations by the Nevada Division of Insurance. It has elected to be taxed under Section 831(b) of the Internal Revenue Code. Pursuant to Section 831(b), if gross premiums do not exceed $ 2,650,000 , then the Captive is taxable solely on its investment income. The Captive is included in the Company's consolidated financial statements and its federal income return.

Revenue Recognition	Revenue Recognition Accounting Standards Codification 606, Revenue from Contracts with Customers (“ASC 606”), establishes a revenue recognition model for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity's contracts to provide goods or services to customers. Most of the Company’s revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as loans and investment securities, and revenue related to mortgage servicing activities, which are subject to other accounting standards. A description of the revenue-generating activities that are within the scope of ASC 606, and included in other income in the Company’s condensed consolidated statements of income are as follows: Trust revenues. The Company generates fee income from providing fiduciary services through its subsidiary, First Mid Wealth Management Company. Fees are billed in arrears based upon the preceding period account balance. Revenue from farm management services is recorded when the service is complete, for example when crops are sold. Brokerage commissions. Revenue is recorded at the beginning of each quarter through billing to customers based on the account asset size on the last day of the previous quarter. If a withdrawal of funds takes place, a prorated refund may occur; this is reflected within the same quarter as the original billing occurred. All performance obligations are met within the same quarter that the revenue is recorded. Insurance commissions. The Company’s insurance agency subsidiary, First Mid Insurance, receives commissions on premiums of new and renewed business policies. First Mid Insurance records commission revenue on direct bill policies as the cash is received. For agency bill policies, First Mid Insurance retains its commission portion of the customer premium payment and remits the balance to the carrier. In both cases, the entire performance obligation is held by the carriers. Service charges on deposits. The Company generates revenue from fees charged for deposit account maintenance, overdrafts, wire transfers, and check fees. The revenue related to deposit fees is recognized at the time the performance obligation is satisfied. ATM/debit card revenue. The Company generates revenue through service charges on the use of its ATM machines and interchange income from the use of Company issued credit and debit cards. The revenue is recognized at the time the service is used and the performance obligation is satisfied. Other income. Treasury management fees and lock box fees are received and recorded after the service performance obligation is completed. Merchant bank card fees are received from various vendors; however, the performance obligation is with the vendors. The Company records gains on the sale of loans and the sale of OREO properties after the transactions are complete and transfer of ownership has occurred. As each of the Company’s facilities is in markets with similar economies, no disaggregation of revenue is necessary.

Adoption of New Accounting Guidance	Adoption of New Accounting Guidance Accounting Standards Update 2022-02, Financial Instruments-Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”). In March 2022, FASB issued ASU 2022-02. The amendments in this update eliminate the accounting guidance and related disclosures for TDRs by creditors in Subtopic 310-40, Receivables—Troubled Debt Restructurings by Creditors , while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty and requiring an entity to disclose current-period gross writeoffs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments—Credit Losses—Measured at Amortized Cost . The amendments in this update were effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years and are applied prospectively, except with respect to the recognition and measurement of TDRs, where an entity has the option to apply a modified retrospective transition method. The adoption of this accounting guidance resulted in updated disclosures within the Company's consolidated financial statements.
