Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Business and Significant Accounting Policies	Nature of Business and Significant Accounting Policies Nature of Business The Company, an Iowa corporation formed in 1983, is a bank holding company under the BHCA and a financial holding company under the GLBA. Our principal executive offices are located at 102 South Clinton Street, Iowa City, Iowa 52240. The Company owns all of the outstanding common stock of MidWest One Bank, an Iowa state non-member bank chartered in 1934 with its main office in Iowa City, Iowa. We operate primarily through MidWest One Bank, our bank subsidiary. On January 31, 2024, the Company completed the acquisition of DNVB, a bank holding company whose wholly-owned banking subsidiary was BOD. Immediately following completion of the acquisition, BOD was merged with and into the Bank. As consideration for the merger, the Company paid cash in the amount of $32.6 million. On June 7, 2024, MidWest One Bank completed the sale of its Florida banking operations for a 7.5% deposit premium, which consisted of one MidWest One Bank branch in each of Naples and Ft. Myers, Florida. Basis of Presentation The accompanying interim condensed consolidated financial statements are prepared in accordance with GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, certain disclosures accompanying annual consolidated financial statements are omitted. In the opinion of management, all significant intercompany accounts and transactions have been eliminated and adjustments, consisting solely of normal recurring accruals and considered necessary for the fair presentation of financial statements for the interim periods, have been included. The current period's results of operations are not necessarily indicative of the results that ultimately may be achieved for the year. The interim condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Form 10-K for the year ended December 31, 2023, filed with the SEC on March 8, 2024. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect: (1) the reported amounts of assets and liabilities, (2) the disclosure of contingent assets and liabilities at the date of the financial statements, and (3) the reported amounts of revenues and expenses during the reporting period. These estimates are based on information available to management at the time the estimates are made. Actual results could differ from those estimates. The results for the three and nine months ended September 30, 2024 may not be indicative of results for the year ending December 31, 2024, or for any other period. All significant accounting policies followed in the preparation of the quarterly financial statements are disclosed in the Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 8, 2024. Segment Reporting The Company’s activities are considered to be one reportable segment for financial reporting purposes. The Company is engaged in the business of commercial and retail banking and trust and investment management services with operations throughout central and eastern Iowa, the Minneapolis/St. Paul metropolitan area, southwestern Wisconsin, and Denver, Colorado. Substantially all income is derived from a diverse base of commercial, mortgage and retail lending activities, and investments. Effect of New Financial Accounting Standards Accounting Guidance Pending Adoption at September 30, 2024 On March 12, 2020, the FASB issued ASU 2020-04, Reference Rate Reform (ASC 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . ASC 848 contains optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform. Certain optional expedients and exceptions for contract modifications and hedging relationships were amended in ASU 2021-01, Reference Rate Reform (Topic 848): Scope Refinement , issued on January 7, 2021. In addition, ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 , deferred the sunset date of Topic 848 from December 31, 2022 to December 31, 2024, after which time entities will no longer be permitted to apply the relief in Topic 848. The adoption of ASU 2020-04 is not expected to have a material impact on the Company’s consolidated financial statements. On November 27, 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. Enhanced disclosures about significant segment expenses are included within this ASU. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with an option to early adopt. The amendments should be applied retrospectively to all prior periods presented in the financial statements, with the segment expense categories and amounts disclosed in prior periods being based on the significant segment expense categories identified and disclosed in the period of adoption. The Company is currently evaluating the impact of ASU 2023-07. On December 14, 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures . Additional transparency about income tax information through improvements to income tax disclosures, primarily related to the rate reconciliation and income taxes paid information, will be required. The amendments are effective for annual periods beginning after December 15, 2024, with an option to early adopt. The amendments should be applied on a prospective basis, with retrospective application being permitted. The Company is currently evaluating the impact of ASU 2023-09. Accounting Guidance Adopted in 2024 On March 29, 2023, the FASB issued ASU 2023-02, Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method . Under this ASU, if certain conditions are met, a reporting entity may elect to account for its tax equity investments by using the proportional amortization method regardless of the program from which it receives income tax credits. The amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with an option to early adopt. The amendments must be applied on either a modified retrospective or a retrospective basis, with certain exceptions for low-income-housing tax credit structures that are not accounted for using the proportional amortization method. The adoption of ASU 2023-02 was applied on a modified retrospective basis and did not have a material impact on the Company's consolidated financial statements.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]
Business Combinations and Divestitures	Business Combinations and Divestitures Business Combinations: On January 31, 2024, the Company acquired 100% of the equity of DNVB through a merger and acquired its wholly-owned banking subsidiary, Bank of Denver, for cash consideration of $32.6 million. The primary reason for the acquisition was to increase our presence in Denver, Colorado. Immediately following the completion of the acquisition, BOD was merged with and into the Bank. The assets acquired and liabilities assumed have been accounted for under the acquisition method of accounting. The assets and liabilities, both tangible and intangible, were recorded at their fair values as of the January 31, 2024 acquisition date, net of any applicable tax effects using a methodology similar to the Company's legacy assets and liabilities (refer to Note 14. Fair Value of Financial Instruments and Fair Value Measurements for additional information regarding the fair value methodology). Initial accounting for the assets acquired and liabilities assumed was incomplete at September 30, 2024. Thus, such amounts recognized in the financial statements have been determined to be provisional. The excess of the consideration paid over the fair value of the net assets acquired is recorded as goodwill. This goodwill is not deductible for tax purposes. The revenue and earnings amount specific to DNVB since the acquisition date that are included in the consolidated results for the three and nine months ended September 30, 2024 are not readily determinable. The disclosures of these amounts are impracticable due to the merging of certain processes and systems at the acquisition date. The table below summarizes the amounts recognized as of the acquisition date for each major class of assets acquired and liabilities assumed: (in thousands) January 31, 2024 Merger consideration Cash consideration $ 32,600 Identifiable net assets acquired, at fair value Assets acquired Cash and due from banks $ 462 Interest earning deposits in banks 3,517 Debt securities 52,493 Loans held for investment 207,095 Premises and equipment 13,070 Core deposit intangible 7,100 Other assets 4,987 Total assets acquired 288,724 Liabilities assumed Deposits $ (224,248) Short-term borrowings (37,500) Other liabilities (3,417) Total liabilities assumed (265,165) Identifiable net assets acquired, at fair value 23,559 Goodwill $ 9,041 For illustrative purposes only, the following table presents certain unaudited pro forma information for the three and nine months ended September 30, 2024 and September 30, 2023. This unaudited, estimated pro forma information was calculated as if DNVB had been acquired as of the beginning of the year prior to the date of acquisition. This unaudited pro forma information combines the historical results of DNVB and the Company and includes adjustments for the estimated impact of certain fair value purchase accounting, interest expense, acquisition-related expenses, and income tax expense for the respective periods. The pro forma information is not indicative of what would have occurred had the acquisition occurred as of the beginning of the year prior to the acquisition. Additionally, the Company expects to achieve further operating cost savings and other business synergies, including revenue growth as a result of the acquisition, which are not reflected in the pro forma amounts that follow. As a result, actual amounts would have differed from the unaudited pro forma information presented.

Debt Securities [Abstract]
Debt Securities	Debt Securities Subsequent to quarter end, as part of a balance sheet repositioning, the Company sold $1.0 billion of debt securities, including securities previously classified as HTM. The decision to sell HTM securities necessitated the reclassification, on September 30, 2024, of all HTM securities to AFS. On September 30, 2024, the HTM securities reclassified had an amortized cost basis of $1.04 billion and a fair value of $870.2 million. The Company recognized an unrealized loss of $45.7 million in accumulated other comprehensive income associated with the HTM securities reclassified, and an impairment loss of $140.4 million in pre-tax earnings associated with the securities sold during the fourth quarter of 2024. The following tables summarize the amortized cost, gross unrealized gains and losses and the resulting fair value of debt securities as of the dates indicated: As of September 30, 2024 (in thousands) Amortized Cost (1) Gross Gross Allowance for Credit Loss related to Debt Securities Fair Value Available for Sale State and political subdivisions $ 603,069 $ 3 $ 20,027 $ — $ 583,045 Mortgage-backed securities 68,024 9 2,757 — 65,276 Collateralized loan obligations 50,470 108 56 — 50,522 Collateralized mortgage obligations 573,621 127 42,980 — 530,768 Corporate debt securities 406,267 127 12,901 — 393,493 Total available for sale debt securities $ 1,701,451 $ 374 $ 78,721 $ — $ 1,623,104 (1) Amortized cost reflects impairment recognized in earnings as follows: $45.9 million of state and political subdivisions, $7.4 million of mortgage-backed securities, $70.0 million of collateralized mortgage obligations, and $17.1 million of corporate debt securities.

Investment securities with a fair value of $885.2 million and $1.16 billion at September 30, 2024 and December 31, 2023, respectively, were pledged on public deposits, securities sold under agreements to repurchase and for other purposes, as required or permitted by law. Accrued interest receivable on available for sale debt securities and held to maturity debt securities is recorded within 'Other Assets,' and is excluded from the estimate of credit losses. At September 30, 2024, the accrued interest receivable on available for sale debt securities was $8.6 million. There was no accrued interest on held to maturity debt securities at September 30, 2024, as the entire portfolio was reclassified as available for sale. At December 31, 2023 the accrued interest receivable on available for sale debt securities and held to maturity debt securities totaled $5.5 million and $3.7 million, respectively.

Management evaluated these securities through a process that included consideration of credit agency ratings and payment history. In addition, management evaluated securities by considering the yield spread to treasury securities and the most recent financial information available. Based on this evaluation, management concluded that the decline in fair value was not attributable to credit losses. As of September 30, 2024, 36 mortgage-backed securities and 90 collateralized mortgage obligations with unrealized losses totaling $45.7 million were held by the Company.

Based on this evaluation, management concluded that the decline in fair value was not attributable to credit losses. As of September 30, 2024, 4 collateralized loan obligations with unrealized losses of $56 thousand were held by the Company. Management evaluated these securities through a process that included consideration of credit agency ratings, priority of cash flows and the amount of over-collateralization. In addition, management may evaluate securities by considering the yield spread to treasury securities and the most recent financial information available. Based on this evaluation, management concluded that the decline in fair value was not attributable to credit losses.

Non-accrual and Delinquent Status Loans are placed on non-accrual status when (1) payment in full of principal and interest is no longer expected or (2) principal or interest has been in default for 90 days or more for all loan types, except owner occupied residential real estate, which are moved to non-accrual at 120 days or more past due, unless the loan is both well secured with marketable collateral and in the process of collection. All loans rated doubtful or worse, and certain loans rated substandard, are placed on non-accrual. A non-accrual loan may be restored to accrual status when (1) all past due principal and interest has been paid (excluding renewals and modifications that involve the capitalizing of interest) or (2) the loan becomes well secured with marketable collateral and is in the process of collection. An established track record of performance is also considered when determining accrual status. Loans are considered past due or delinquent when the contractual principal or interest due in accordance with the terms of the loan agreement or any portion thereof remains unpaid after the due date of the scheduled payment.

The interest income recognized on loans that were on nonaccrual status for the nine months ended September 30, 2024 and September 30, 2023 was $960 thousand and $186 thousand, respectively. Credit Quality Information The Company aggregates 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, credit documentation, and other factors. The Company analyzes loans individually to classify the loans as to credit risk. This analysis includes non-homogenous loans, such as agricultural, commercial and industrial, commercial real estate and non-owner occupied residential real estate loans. Loans not meeting the criteria described below that are analyzed individually are considered to be pass-rated. The Company uses the following definitions for risk ratings: Special Mention/Watch - A special mention/watch asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Special mention/watch assets are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification. Substandard - Substandard loans are inadequately protected by the current net worth 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 Company 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, on the basis of currently known facts, conditions and values, highly questionable and improbable. Loss - Loans classified as loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the loan has absolutely no recovery or salvage value but rather it is not practical or desirable to defer writing off this basically worthless asset even though partial recovery may be affected in the future. Homogenous loans, including owner occupied residential real estate and consumer loans, are not individually risk rated. Instead, these loans are categorized based on performance: performing and nonperforming. Nonperforming loans include those loans on nonaccrual and loans greater than 90 days past due and on accrual.

In addition, management utilized qualitative factors to adjust the calculated ACL as appropriate. Qualitative factors are based on management’s judgment of company, market, industry or business specific data, changes in underlying loan composition of specific portfolios, trends relating to credit quality, delinquency, non-performing and adversely rated loans, and reasonable and supportable forecasts of economic conditions. The increase in the ACL between September 30, 2024 and December 31, 2023 reflects $3.1 million of day 1 credit loss expense related to acquired DNVB loans, as well as additional reserve taken to support loan growth. Partially offsetting these identified increases was a $1.9 million reduction to the ACL for allowance allocated to the loans sold with our Florida banking operations. Net loan charge-offs were $1.7 million for the three months ended September 30, 2024 as compared to net loan charge-offs of $0.5 million for the three months ended September 30, 2023. Net loan charge-offs were $2.4 million for the nine months ended September 30, 2024 as compared to net loan charge-offs of $1.7 million for the nine months ended September 30, 2023. We have made a policy election to report interest receivable as a separate line on the balance sheet. Accrued interest receivable, which is recorded within 'Other Assets', totaled $22.0 million at September 30, 2024.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives, Hedging Activities and Balance Sheet Offsetting	Derivatives, Hedging Activities and Balance Sheet Offsetting The following table presents the total notional amounts and gross fair values of the Company’s derivatives as of the dates indicated. The derivative asset and liability balances are presented on a gross basis, prior to the application of master netting agreements, as included in other assets and other liabilities, respectively, on the consolidated balance sheets. The fair values of the Company's derivative instrument assets and liabilities are summarized as follows: As of September 30, 2024 As of December 31, 2023 Notional Amount Fair Value Notional Amount Fair Value (in thousands) Assets Liabilities Assets Liabilities Designated as hedging instruments: Fair value hedges: Interest rate swaps - loans $ 49,804 $ 1,573 $ 1,540 $ 41,101 $ 2,071 $ 902 Interest rate swaps - securities 150,000 — 532 150,000 — 821 Cash flow hedges Interest rate swaps 200,000 74 574 200,000 940 264 Total $ 399,804 $ 1,647 $ 2,646 $ 391,101 $ 3,011 $ 1,987 Not designated as hedging instruments: Interest rate swaps $ 652,740 $ 23,102 $ 23,118 $ 432,648 $ 22,028 $ 22,038 RPAs - protection sold 54,266 8 — 18,778 4 — RPAs - protection purchased 30,175 — 1 31,145 — 9 Interest rate lock commitments 2,704 40 — 1,461 50 — Interest rate forward loan sales contracts 2,750 — 1 2,075 — 23 Total $ 742,635 $ 23,150 $ 23,120 $ 486,107 $ 22,082 $ 22,070 Derivatives Designated as Hedging Instruments The Company uses derivative instruments to hedge its exposure to economic risks. Certain hedging relationships are formally designated and qualify for hedge accounting under GAAP as fair value or cash flow hedges. Fair Value Hedges - Derivatives are designated as fair value hedges to limit the Company's exposure to changes in the fair value of assets or liabilities due to movements in interest rates. The Company entered into pay-fixed receive-floating interest rate swaps to manage its exposure to changes in fair value in certain fixed-rate assets, including AFS debt securities and loans. The gain or loss on the loan fair value hedge derivative, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in interest income. The change in the fair value of the available for sale securities attributable to changes in the hedged risk is recorded in accumulated other comprehensive income and subsequently reclassified into interest income, as applicable, in the same period(s) to offset the changes in the fair value of the swap, which is also recognized in interest income. Cash Flow Hedges - Derivatives are designated as cash flow hedges in order to minimize the variability in cash flows of earning assets or forecasted transactions caused by movement in interest rates. The Company has previously entered into pay-fixed receive-variable interest rate swaps to hedge against adverse fluctuations in interest rates by reducing exposure to variability in cash flows relating to interest payments on the Company's variable rate debt, including brokered deposits. The gain or loss on the derivatives is recorded in accumulated other comprehensive income and subsequently reclassified into interest expense, as applicable, in the same period(s) during which the hedged transaction affects earnings. During the 12 months following September 30, 2024, the Company estimates that an additional $48.0 thousand of income will be reclassified into interest expense. The table below presents the effect of cash flow hedge accounting on AOCI for the three and nine months ended September 30, 2024 and 2023: Amount of Gain (Loss) Recognized in AOCI on Derivative Location of Gain (Loss) Reclassified from AOCI into Income Amount of Gain Reclassified from AOCI into Income Three Months Ended September 30, Three Months Ended September 30, (in thousands) 2024 2023 2024 2023 Interest rate swaps $ (2,388) $ 1,829 Interest Expense $ 763 $ 761 Nine Months Ended September 30, Nine Months Ended September 30, (in thousands) 2024 2023 2024 2023 Interest rate swaps $ 1,162 $ 5,288 Interest Expense $ 2,338 $ 999 The table below presents the effect of the Company’s derivative financial instruments designated as hedging instruments on the consolidated statements of income for the periods indicated: Location and Amount of Gain or Loss Recognized in Income on Hedging Relationships For the Three Months Ended September 30, For the Nine Months Ended September 30, 2024 2023 2024 2023 (in thousands) Interest Income Other Income Interest Income Other Income Interest Income Other Income Interest Income Other Income Income and expense included in the consolidated statements of income related to the effects of fair value or cash flow hedges are recorded $ 446 $ — $ 317 $ — $ 1,336 $ — $ 666 $ — The effects of fair value and cash flow hedging: Gain (loss) on fair value hedging relationships in subtopic 815-20: Interest contracts - loans: Hedged items 2,135 — (747) — 1,139 — (212) — Derivative designated as hedging instruments (1,852) — 964 — (322) — 1,219 — Interest contracts - securities: Hedged items 687 — (454) — (299) — (454) — Derivative designated as hedging instruments (524) — 560 — 819 — 560 — As of September 30, 2024, the following amounts were recorded on the balance sheet related to cumulative basis adjustment for fair value hedges: Line Item in the Balance Sheet in Which the Hedged Item is Included Carrying Amount of the Hedged Assets Cumulative Amount of Fair Value Hedging Adjustment Included in the Carrying Amount of the Hedged Asset (in thousands) Loans $ 49,824 $ (24) Securities $ 150,520 $ 520 Derivatives Not Designated as Hedging Instruments Interest Rate Swaps - The Company periodically enters into commercial loan interest rate swap agreements in order to provide commercial loan customers with the ability to convert from variable to fixed interest rates. These derivative contracts relate to transactions in which the Company enters into an interest rate swap with a customer, while simultaneously entering into an offsetting interest rate swap with an institutional counterparty. Credit Risk Participation Agreements -The Company enters into RPAs to manage the credit exposure on interest rate contracts associated with a syndicated loan or participation agreement. The Company may enter into protection purchased RPAs with institutional counterparties to decrease or increase its exposure to a borrower. Under the RPA, the Company will receive or make payment if a borrower defaults on the related interest rate contract. The notional amount of the RPAs reflects the Company’s pro-rata share of the derivative instrument. Interest Rate Forward Loan Sales Contracts & Interest Rate Lock Commitments - The Company enters into forward delivery contracts to sell residential mortgage loans at specific prices and dates in order to hedge the interest rate risk in its portfolio of mortgage loans held for sale and its residential mortgage interest rate lock commitments. The following table presents the net gains (losses) recognized on the consolidated statements of income related to the derivatives not designated as hedging instruments for the periods indicated: Location in the Consolidated Statements of Income For the Three Months Ended September 30, For the Nine Months Ended September 30, (in thousands) 2024 2023 2024 2023 Interest rate swaps Other income $ (6) $ (27) $ (5) $ (27) RPAs Other income 5 1 12 70 Interest rate lock commitments Loan revenue (10) (51) (10) 11 Interest rate forward loan sales contracts Loan revenue (14) (5) 21 14 Total $ (25) $ (82) $ 18 $ 68 Offsetting of Derivatives The Company has entered into agreements with certain counterparty financial institutions, which include master netting agreements. However, the Company has elected to account for all derivatives with counterparty financial institutions on a gross basis. The Company manages the risk of default by its borrower counterparties through its normal loan underwriting and credit monitoring policies and procedures. The table below presents gross derivatives and the respective collateral received or pledged in the form of other financial instruments as of September 30, 2024 and December 31, 2023, which are generally marketable securities and/or cash. The collateral amounts in the table below are limited to the outstanding balances of the related asset or liability (after netting is applied); thus instances of over-collateralization are not shown. Further, the net amounts of derivative assets or liabilities can be reconciled to the tabular disclosure of fair value. The tabular disclosure of fair value provides the location that derivative assets and liabilities are presented on the consolidated balance sheets.

Each trust’s ability to pay amounts due on the trust preferred securities is solely dependent upon the Company making payment on the related junior subordinated notes. The Company’s obligation under the junior subordinated notes and other relevant trust agreements, in aggregate, constitutes a full and unconditional guarantee by the Company of each trust’s obligations under the trust preferred securities issued by each trust. The Company has the right to defer payment of interest on the junior subordinated notes and, therefore, distributions on the trust preferred securities, for up to five years, but not beyond the stated maturity date in the table above. During any such deferral period the Company may not pay cash dividends on its stock and generally may not repurchase its stock. Subordinated Debentures On July 28, 2020, the Company completed the private placement offering of $65.0 million of its subordinated notes, of which $63.75 million have been exchanged for subordinated notes registered under the Securities Act of 1933. The 5.75% fixed-to-floating rate subordinated notes are due July 30, 2030. On July 30, 2025, the interest rate on the subordinated notes will reset quarterly to a floating rate of three-month term SOFR plus 5.68%. At September 30, 2024, 100% of the subordinated notes qualified as Tier 2 capital. Per applicable Federal Reserve rules and regulations, the amount of the subordinated notes qualifying as Tier 2 regulatory capital will be phased-out by 20% of the amount of the subordinated notes in each of the five years beginning on the fifth anniversary preceding the maturity date of the subordinated notes. At September 30, 2024 and December 31, 2023, the Company had outstanding subordinated debentures of $64.2 million and $64.1 million, respectively.

Principal and interest are payable quarterly, and began on September 30, 2022. Interest accrues at the monthly reset term SOFR plus 1.55%. The credit agreement includes customary covenants requiring the Company to, among other things, maintain minimum levels of both regulatory capital and certain financial ratios; the Company certifies compliance with the covenants on a quarterly basis. On February 12, 2024, the credit agreement, including certain of its covenants, was amended. On September 30, 2024, the credit agreement was again amended to include certain terms and to extend the maturity date of the line of credit to September 30, 2025. As a member of the FHLBDM, the Bank may borrow funds from the FHLB, provided the Bank is able to pledge an adequate amount of qualified assets to secure the borrowings. In addition, the FHLB has established a credit capacity limit to the Bank that is equal to 45% of the Bank’s total assets. This credit capacity limit includes short-term and long-term borrowings, federal funds, letters of credit and other sources of credit exposure to the FHLB. Advances from the FHLB are collateralized primarily by one- to four-family residential, commercial and agricultural real estate first mortgages equal to various percentages of the total outstanding notes.

Broker-Dealer, Net Capital Requirement, SEC Regulation [Abstract]
Regulatory Capital Requirements and Restrictions on Subsidiary Cash	Regulatory Capital Requirements and Restrictions on Subsidiary Cash Regulatory Capital and Reserve Requirement - The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company's consolidated financial statements. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors. As of both September 30, 2024 and December 31, 2023, the Bank was not required to maintain reserve balances in cash on hand or on deposit with Federal Reserve Banks, and therefore no amounts were held in reserve for each of these periods. A comparison of the Company's and the Bank's capital, with the corresponding minimum regulatory requirements in effect at September 30, 2024 and December 31, 2023, is presented below: Actual For Capital Adequacy Purposes With Capital Conservation Buffer (1) To Be Well Capitalized Under Prompt Corrective Action Provisions (dollars in thousands) Amount Ratio Amount Ratio Amount Ratio At September 30, 2024 Consolidated: Total capital/risk weighted assets $696,014 12.96% $564,115 10.50% N/A N/A Tier 1 capital/risk weighted assets 574,673 10.70 456,664 8.50 N/A N/A Common equity tier 1 capital/risk weighted assets 532,247 9.91 376,077 7.00 N/A N/A Tier 1 leverage capital/average assets 574,673 8.78 261,824 4.00 N/A N/A MidWest One Bank: Total capital/risk weighted assets $690,462 12.88% $562,721 10.50% $535,925 10.00% Tier 1 capital/risk weighted assets 634,121 11.83 455,536 8.50 428,740 8.00 Common equity tier 1 capital/risk weighted assets 634,121 11.83 375,147 7.00 348,351 6.50 Tier 1 leverage capital/average assets 634,121 9.69 261,644 4.00 327,055 5.00 At December 31, 2023 Consolidated: Total capital/risk weighted assets $668,748 12.53% $560,596 10.50% N/A N/A Tier 1 capital/risk weighted assets 554,177 10.38 453,816 8.50 N/A N/A Common equity tier 1 capital/risk weighted assets 511,884 9.59 373,731 7.00 N/A N/A Tier 1 leverage capital/average assets 554,177 8.58 258,487 4.00 N/A N/A MidWest One Bank: Total capital/risk weighted assets $656,027 12.49% $551,658 10.50% $525,388 10.00% Tier 1 capital/risk weighted assets 606,456 11.54 446,580 8.50 420,310 8.00 Common equity tier 1 capital/risk weighted assets 606,456 11.54 367,772 7.00 341,502 6.50 Tier 1 leverage capital/average assets 606,456 9.39 258,339 4.00 322,924 5.00 (1)

Commitments and Contingencies

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Credit-related financial instruments - The Bank is a party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, commitments to sell loans, and standby letters of credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the balance sheets. The Bank uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments. The following table summarizes the Bank’s commitments as of the dates indicated: September 30, 2024 December 31, 2023 (in thousands) Commitments to extend credit $ 1,142,569 $ 1,203,001 Commitments to sell loans 3,283 1,045 Standby letters of credit 7,246 7,795 Total $ 1,153,098 $ 1,211,841 The Bank’s exposure to credit loss in the event of nonperformance by the counterparty to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Bank evaluates each customer’s creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Bank upon extension of credit, is based on management’s credit evaluation of the party. Collateral held varies, but may include accounts receivable, crops, livestock, inventory, property and equipment, residential real estate and income-producing commercial properties. Commitments to sell loans are agreements to sell loans held for sale to third parties at an agreed upon price. Standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements and, generally, have terms of one year or less. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Bank holds collateral, which may include accounts receivable, inventory, property, equipment and income-producing properties, that support those commitments, if deemed necessary. In the event the customer does not perform in accordance with the terms of the agreement with the third party, the Bank would be required to fund the commitment. The maximum potential amount of future payments the Bank could be required to make is represented by the contractual amount shown in the summary above. If the commitment is funded, the Bank would be entitled to seek recovery from the customer. Liability for Off-Balance Sheet Credit Losses - The Company records a liability for off-balance sheet credit losses through a charge to credit loss expense (or a reversal of credit loss expense) on the Company's consolidated statements of income and other liabilities on the Company's consolidated balance sheets. At September 30, 2024 and December 31, 2023, the liability for off-balance-sheet credit losses totaled $5.2 million and $4.6 million, respectively. For the nine months ended September 30, 2024, $0.6 million credit loss expense was recorded, with no credit loss expense recorded for the nine months ended September 30, 2023. Litigation - In the normal course of business, the Company and its subsidiaries have been named, from time to time, as defendants in various legal actions. Certain of the actual or threatened legal actions may include claims for substantial compensatory and/or punitive damages or claims for indeterminate amounts of damages. Management, after consulting with legal counsel, is of the opinion that the ultimate liability, if any, resulting from these pending or threatened actions and proceedings will not have a material effect on the financial statements of the Company. Concentrations of credit risk - Substantially all of the Bank’s loans, commitments to extend credit and standby letters of credit have been granted to customers in the Bank’s market areas. Although the loan portfolio of the Bank is diversified, approximately 65% of the loans are real estate loans, excluding farmland, and approximately 7% are agriculturally related. The concentrations of credit by type of loan are set forth in Note 4. Loans Receivable and the Allowance for Credit Losses

Fair Value of Financial Instrum

Fair Value of Financial Instruments and Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value of Financial Instruments and Fair Value Measurements	Fair Value of Financial Instruments and Fair Value Measurements Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: • Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2 – Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. • Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. For additional information regarding the valuation methodologies used to measure the Company's assets recorded at fair value, and for estimating fair value for financial instruments not recorded at fair value, see Note 1. Nature of Business and Significant Accounting Policies and Note 20. Estimated Fair Value of Financial Instruments and Fair Value Measurements to the consolidated financial statements in the Company's 2023 Annual Report on Form 10-K, filed with the SEC on March 8, 2024. The Company uses fair value to measure certain assets and liabilities on a recurring basis, primarily available for sale debt securities, derivatives and mortgage servicing rights. For assets measured at the lower of cost or fair value, the fair value measurement criteria may or may not be met during a reporting period, and such measurements are therefore considered “nonrecurring ” for purposes of disclosing the Company's fair value measurements. Fair value is used on a nonrecurring basis to adjust carrying values for collateral dependent individually analyzed loans and foreclosed assets. Recurring Basis The following tables summarize assets and liabilities measured at fair value on a recurring basis as of September 30, 2024 and December 31, 2023, by level within the fair value hierarchy: Fair Value Measurement at September 30, 2024 Using (in thousands) Total Level 1 Level 2 Level 3 Assets: Available for sale debt securities: State and political subdivisions $ 583,045 $ — $ 583,045 $ — Mortgage-backed securities 65,276 — 65,276 — Collateralized loan obligations 50,522 — 50,522 — Collateralized mortgage obligations 530,768 — 530,768 — Corporate debt securities 393,493 — 393,493 — Derivative assets 24,797 — 24,757 40 Mortgage servicing rights 12,068 — 12,068 — Liabilities: Derivative liabilities $ 25,766 $ — $ 25,766 $ — Fair Value Measurement at December 31, 2023 Using (in thousands) Total Level 1 Level 2 Level 3 Assets: Debt securities available for sale: State and political subdivisions $ 130,139 $ — $ 130,139 $ — Mortgage-backed securities 5,311 — 5,311 — Collateralized loan obligations 50,437 — 50,437 — Collateralized mortgage obligations 169,196 — 169,196 — Corporate debt securities 440,051 — 440,051 — Derivative assets 25,093 — 25,043 50 Mortgage servicing rights 13,333 — 13,333 — Liabilities: Derivative liabilities $ 24,057 $ — $ 24,057 $ — There were no transfers of assets between Level 3 and other levels of the fair value hierarchy during the nine months ended September 30, 2024 or the year ended December 31, 2023.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying interim condensed consolidated financial statements are prepared in accordance with GAAP for interim financial information and pursuant to the requirements for reporting on Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, certain disclosures accompanying annual consolidated financial statements are omitted. In the opinion of management, all significant intercompany accounts and transactions have been eliminated and adjustments, consisting solely of normal recurring accruals and considered necessary for the fair presentation of financial statements for the interim periods, have been included. The current period's results of operations are not necessarily indicative of the results that ultimately may be achieved for the year. The interim condensed consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements and notes thereto included in our Form 10-K for the year ended December 31, 2023, filed with the SEC on March 8, 2024.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect: (1) the reported amounts of assets and liabilities, (2) the disclosure of contingent assets and liabilities at the date of the financial statements, and (3) the reported amounts of revenues and expenses during the reporting period. These estimates are based on information available to management at the time the estimates are made. Actual results could differ from those estimates. The results for the three and nine months ended September 30, 2024 may not be indicative of results for the year ending December 31, 2024, or for any other period.
Segment Reporting	Segment Reporting The Company’s activities are considered to be one reportable segment for financial reporting purposes. The Company is engaged in the business of commercial and retail banking and trust and investment management services with operations throughout central and eastern Iowa, the Minneapolis/St. Paul metropolitan area, southwestern Wisconsin, and Denver, Colorado. Substantially all income is derived from a diverse base of commercial, mortgage and retail lending activities, and investments.
Effect of New Financial Accounting Standards	Effect of New Financial Accounting Standards Accounting Guidance Pending Adoption at September 30, 2024 On March 12, 2020, the FASB issued ASU 2020-04, Reference Rate Reform (ASC 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . ASC 848 contains optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform. Certain optional expedients and exceptions for contract modifications and hedging relationships were amended in ASU 2021-01, Reference Rate Reform (Topic 848): Scope Refinement , issued on January 7, 2021. In addition, ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848 , deferred the sunset date of Topic 848 from December 31, 2022 to December 31, 2024, after which time entities will no longer be permitted to apply the relief in Topic 848. The adoption of ASU 2020-04 is not expected to have a material impact on the Company’s consolidated financial statements. On November 27, 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. Enhanced disclosures about significant segment expenses are included within this ASU. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with an option to early adopt. The amendments should be applied retrospectively to all prior periods presented in the financial statements, with the segment expense categories and amounts disclosed in prior periods being based on the significant segment expense categories identified and disclosed in the period of adoption. The Company is currently evaluating the impact of ASU 2023-07. On December 14, 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures . Additional transparency about income tax information through improvements to income tax disclosures, primarily related to the rate reconciliation and income taxes paid information, will be required. The amendments are effective for annual periods beginning after December 15, 2024, with an option to early adopt. The amendments should be applied on a prospective basis, with retrospective application being permitted. The Company is currently evaluating the impact of ASU 2023-09. Accounting Guidance Adopted in 2024 On March 29, 2023, the FASB issued ASU 2023-02, Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method . Under this ASU, if certain conditions are met, a reporting entity may elect to account for its tax equity investments by using the proportional amortization method regardless of the program from which it receives income tax credits. The amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with an option to early adopt. The amendments must be applied on either a modified retrospective or a retrospective basis, with certain exceptions for low-income-housing tax credit structures that are not accounted for using the proportional amortization method. The adoption of ASU 2023-02 was applied on a modified retrospective basis and did not have a material impact on the Company's consolidated financial statements.
Derivatives Designated as Hedging Instruments	Derivatives Designated as Hedging Instruments The Company uses derivative instruments to hedge its exposure to economic risks. Certain hedging relationships are formally designated and qualify for hedge accounting under GAAP as fair value or cash flow hedges. Fair Value Hedges - Derivatives are designated as fair value hedges to limit the Company's exposure to changes in the fair value of assets or liabilities due to movements in interest rates. The Company entered into pay-fixed receive-floating interest rate swaps to manage its exposure to changes in fair value in certain fixed-rate assets, including AFS debt securities and loans. The gain or loss on the loan fair value hedge derivative, as well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in interest income. The change in the fair value of the available for sale securities attributable to changes in the hedged risk is recorded in accumulated other comprehensive income and subsequently reclassified into interest income, as applicable, in the same period(s) to offset the changes in the fair value of the swap, which is also recognized in interest income. Cash Flow Hedges - Derivatives are designated as cash flow hedges in order to minimize the variability in cash flows of earning assets or forecasted transactions caused by movement in interest rates. The Company has previously entered into pay-fixed receive-variable interest rate swaps to hedge against adverse fluctuations in interest rates by reducing exposure to variability in cash flows relating to interest payments on the Company's variable rate debt, including brokered deposits. The
Fair Value Measurements	Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: • Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2 – Significant other observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. • Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. For additional information regarding the valuation methodologies used to measure the Company's assets recorded at fair value, and for estimating fair value for financial instruments not recorded at fair value, see Note 1. Nature of Business and Significant Accounting Policies and Note 20. Estimated Fair Value of Financial Instruments and Fair Value Measurements to the consolidated financial statements in the Company's 2023 Annual Report on Form 10-K, filed with the SEC on March 8, 2024. The Company uses fair value to measure certain assets and liabilities on a recurring basis, primarily available for sale debt securities, derivatives and mortgage servicing rights. For assets measured at the lower of cost or fair value, the fair value measurement criteria may or may not be met during a reporting period, and such measurements are therefore considered “nonrecurring ” for purposes of disclosing the Company's fair value measurements. Fair value is used on a nonrecurring basis to adjust carrying values for collateral dependent individually analyzed loans and foreclosed assets.
