UNAUDITED PRO FORMA COMBINED CONDENSED

CONSOLIDATED FINANCIAL INFORMATION

The following unaudited pro forma combined condensed financial information and explanatory notes show the impact on the historical financial position and results of operations of MidWestOne Financial Group, Inc. ("MidWestOne") and ATBancorp and have been prepared to illustrate the effects of the merger involving MidWestOne and ATBancorp under the acquisition method of accounting. Under the acquisition method of accounting, the assets and liabilities of ATBancorp, as of the effective date of the merger, will be recorded by MidWestOne at their respective fair values and the excess of the merger consideration over the fair value of ATBancorp’s net assets will be recorded to goodwill.The unaudited pro forma combined condensed balance sheet as of December 31, 2018 gives effect to the merger as if it occurred on that date. The unaudited pro forma combined condensed income statement for the year ended December 31, 2018 gives effect to the merger as if it occurred on January 1, 2018. The effective date of the merger was May 1, 2019.

In connection with the plan to integrate the operations of MidWestOne and ATBancorp following the completion of the merger, MidWestOne anticipates that it will incur nonrecurring charges, such as costs associated with systems implementation, severance and other costs related to exit or disposal activities. Refer to the footnotes to the unaudited pro forma combined condensed financial information below for additional information on merger-related costs. These charges will affect the results of operations of MidWestOne and ATBancorp, as well as those of the combined company following the completion of the merger, in the period in which they are recorded. The unaudited pro forma combined condensed consolidated income statements do not include the effects of the non-recurring costs associated with any restructuring or integration activities resulting from the merger or any anticipated disposition of assets that may result from integration.

The pro forma adjustments reflected in the unaudited pro forma combined condensed financial information are subject to change and may vary materially from the actual values that will be recorded at the time the accounting for the merger is completed. Adjustments may include, but not be limited to:

• capital used or generated in ATBancorp’s operations between the signing of the merger Agreement and completion of the merger;

• changes in the fair values of ATBancorp’s assets and liabilities;

• other changes in ATBancorp's net assets that occurred prior to completion of the merger, which could cause material changes in the information presented below; and

• the actual financial results of the combined company.

The unaudited pro forma combined condensed consolidated financial information is provided for informational purposes only. The unaudited pro forma combined condensed consolidated financial information is not necessarily, and should not be assumed to be, an indication of the results that would have been achieved had the transaction been completed as of the dates indicated or that may be achieved in the future. The preparation of the unaudited pro forma combined condensed consolidated financial information required management to make certain assumptions and estimates. The unaudited pro forma combined condensed consolidated financial information is based on, and should be read together with, the historical consolidated financial statements and related notes of MidWestOne contained in its Annual Report on Form 10-K for the year ended December 31, 2018.

Notes to Unaudited Pro Forma Condensed Combined Financial Information

Note 1—Basis of Presentation

The unaudited pro forma combined condensed consolidated financial information has been prepared using the acquisition method of accounting for business combinations. The unaudited pro forma combined condensed consolidated statement of income for the year ended December 31, 2018 is presented as if the acquisition had occurred on January 1, 2018. This information is not intended to reflect actual results that would have been achieved had the acquisition actually occurred on that date. The pro forma adjustments are preliminary, based on estimates, and are subject to change as more information becomes available and after final analysis of the fair values of both tangible and intangible assets acquired and liabilities assumed are completed. Accordingly, the final fair value adjustments may be materially different from those presented in this document.

Certain historical data of ATBancorp has been reclassified on a pro forma basis to conform to MidWestOne's classifications.    

Note 2—Purchase Price

Each outstanding share of common stock, no par value per share, of ATBancorp was exchanged for (i) 117.55 shares of common stock, $1.00 par value per share, of MidWestOne; and (ii) $992.51 in cash.

Note 3—Allocation of Purchase Price of ATBancorp

Under the acquisition method of accounting, ATBancorp's assets and liabilities and any identifiable intangible assets are required to be adjusted to their estimated fair values. The excess of the purchase price over the fair value of the net assets acquired, net of deferred taxes, is allocated to goodwill. Estimated fair value adjustments included in the pro forma financial information is based upon available information, and certain assumptions considered reasonable, and may be revised as additional information becomes available. The following are the pro forma merger consideration transfered by MidWestOne, the estimated fair value of assets acquired (including identifiable intangible assets) and liabilities assumed from ATBancorp, and the goodwill created by the merger, at the date indicated.
