Third Amendment to the Credit Agreement by and

This THIRD AMENDMENT TO CREDIT AGREEMENT (this “Amendment”), made and entered into as of February 12, 2024, is by and between MidWestOne Financial Group, Inc. a corporation organized under the laws of the State of Iowa (the “Borrower”), and U.S. Bank National Association, a national banking association (the “Bank”).

1.    The Bank and the Borrower entered into a Credit Agreement dated as of June 7, 2022, as amended by that certain First Amendment to Credit Agreement dated as of September 30, 2022 and that certain Second Amendment to Credit Agreement dated as of September 19, 2023 (as amended, the “Credit Agreement”); and

2.    The Borrower desires to amend certain provisions of the Credit Agreement, and the Bank has agreed to make such amendments, subject to the terms and conditions set forth in this Amendment.

NOW, THEREFORE, for good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto hereby covenant and agree to be bound as follows:

Section 1.Capitalized Terms. Capitalized terms used and not otherwise defined herein shall have the meanings assigned to them in the Credit Agreement, unless the context otherwise requires.

Section 2.Amendments. The Credit Agreement is hereby amended as follows:

2.1Section 1.1 – Defined Terms. Section 1.1 of the Credit Agreement is amended by inserting the definitions of “Average Total Assets”, “Net Income”, and “Return on Assets” in their respective entireties, to read as follows:

“Net Income” means respect to any Person for the four fiscal quarters most recently ended, the net income of such Person, consolidated with its Subsidiaries, after deductions for all expenses, including, but not limited to, income taxes if any, Interest Expense, and non-cash charges or expenses, including depreciation and amortization, all as determined in accordance with GAAP.

“Return on Assets” means Net Income divided by Average Total Assets.

Section 1.1 of the Credit Agreement is further amended by restating the definitions of “Monthly Reset Term SOFR Rate” and “Term SOFR” to read in their respective entireties as follows:

“Monthly Reset Term SOFR Rate”: Means the greater of (a) zero and (b) the one-month forward-looking term rate based on SOFR quoted by the Bank from the Term SOFR Administrator’s Website (or other commercially available source providing such quotations as may be selected by the Bank from time to time) (“Term SOFR”), which shall be that one-month Term SOFR rate in effect two New York Banking Days prior to the Rate Adjustment Date, adjusted for any reserve requirement and any subsequent costs arising from a change in government regulation; provided that if the Term SOFR rate is not published on such New York Banking Day due to a holiday or other circumstance that the Bank deems in its sole discretion to be temporary, the applicable Term SOFR rate shall be the Term SOFR rate last published prior to such New York Banking Day. If the initial Revolving Loan or the Term Loan Advance under this Agreement occurs other than on the Rate Adjustment Date, the initial one-month Term SOFR rate in effect two New York Banking Days prior to the later of (a) the immediately preceding Rate Adjustment Date and (b) the Closing Date, which rate plus the Applicable Margin shall be in effect until the next Rate Adjustment Date.

“Term SOFR” has the meaning given such term in the definition of “Monthly Reset Term SOFR Rate.”

Section 1.1 of the Credit Agreement is further amended to delete the definition of “Fixed Charge Coverage Ratio” as it appears therein.

2.2Section 2.4(c) – Term SOFR Unavailability. Section 2.4(c) of the Credit Agreement is restated in its entirety to read as follows:

(c)    Term SOFR Unavailability. If the Bank has determined in its sole discretion that (i) the administrator of Term SOFR, or any relevant agency or authority for such administrator, of Term SOFR (or any substitute index which replaces Term SOFR (Term SOFR or such replacement, the “Benchmark”)) has announced that such Benchmark will no longer be provided, (ii) any relevant agency or authority has announced that such Benchmark is no longer representative, or (iii) any similar circumstance exists such that such Benchmark has become permanently unavailable or ceased to exist, the Bank will (x) replace such Benchmark with a replacement rate or (y) if any such circumstance applies to fewer than all tenors of such Benchmark used for determining an interest period hereunder, discontinue the availability of the affected interest periods. In the case of Term SOFR, such replacement rate will be Daily Simple SOFR. In the case of the replacement of a rate other than Term SOFR, the Bank may add a spread adjustment selected by the Bank, taking into consideration any selection or recommendation of a replacement rate by any relevant agency or authority, and evolving or prevailing market practice. In connection with the selection and implementation of any such replacement rate, the Bank may make any technical, administrative or operational changes that the Bank decides may be appropriate to reflect the adoption and implementation of such replacement rate. Without limitation of the foregoing, in the case of a transition to Daily Simple SOFR, the Bank will remove any option to select another rate that may change or is reset on

a daily basis, including, without limitation, the Prime Rate. The Bank does not warrant or accept any responsibility for the administration or submission of, or any other matter related to, Term SOFR or with respect to any alternative or successor rate thereto, or replacement rate thereof, including without limitation whether any such alternative, successor or replacement rate will have the same value as, or be economically equivalent to, Term SOFR.

2.3Section 6.18 – Return on Assets. Section 6.18 of the Credit Agreement is restated in its entirety to read as follows:
